AEROSOL DISPENSING DEVICES
A multidirectional aerosol dispensing device and methods of utilizing the device in a variety of positions, including an inverted position, to dispense an aerosol product. The device may include an aerosol container, an undercap, and an actuator. An aerosol valve may be located at a bottom portion of the aerosol container. The aerosol valve may have a valve stem for displacing the aerosol valve from a biased closed position to an open position upon a movement of the valve stem to discharge the aerosol product from the valve stem. The undercap may be mounted to the aerosol container with the top portion of the undercap being adjacent to the bottom portion of the aerosol container. The bottom portion of the undercap may terminate in a base surface for supporting the device on a supporting surface to store the aerosol dispensing device in an inverted position.
This application claims the benefit, under 35 U.S.C. § 119 (e), to U.S. Provisional Application No. 63/519,384, filed Aug. 14, 2023, the entire disclosure of which is fully incorporated by reference herein.
FIELD OF THE INVENTIONThe present disclosure relates generally to aerosol dispensers and more specifically to multi-directional aerosol dispensers.
BACKGROUNDConsumers desire to spray some aerosol products in a multitude of orientations (e.g., at the floor, eye level, overhead etc.) while the container is upright or inverted. Traditional aerosol actuators, however, tend to be designed for either upright or inverted dispensing.
Upright dispensing is most common and includes triggers and button actuators. These actuators are difficult or impossible for a consumer to dispense when the container is inverted. Additionally, the presence of a dip tube may mean only the aerosol gas is dispensed rather than product.
Inverted dispensing is less common (e.g., spray paint for lines on a field, or shaving cream). The lack of a dip tube in inverted dispensing apparatuses may mean that only aerosol gas is dispensed when product is actuated upright. Additionally, inverted dispensing may be unintuitive for a consumer product if the product is stored with the valve upright (e.g., suggesting product should be stored and dispensed upright)
A need, therefore, exists for an aerosol package that may dispense in an upright and an inverted position. Additionally, a need exists for an aerosol package that may be stored on a shelf or resting plane in an inverted position without dripping, leaking or accidently dispensing. In particular, a need exists for an aerosol package that may dispense a pest control composition, such as an herbicide or an insecticide, in an upright and an inverted position.
The discussion of shortcomings and needs existing in the field prior to the present disclosure is in no way an admission that such shortcomings and needs were recognized by those skilled in the art prior to the present disclosure.
SUMMARYVarious configurations solve the above-mentioned problems and provide methods and devices useful for dispensing an aerosol product from a variety of positions, including in an upright and an inverted position to provide a better ergonomic experience for a user as well as to help the user hit a targeted area, object, or pest with the aerosol product. The device may be conveniently stored on a shelf or resting plane in an inverted position without dripping, leaking or accidently dispensing.
Various configurations relate to a multidirectional aerosol dispensing device. The device may comprise an aerosol container extending between a top portion and a bottom portion for containing an aerosol product and an aerosol propellant therein. The multidirectional aerosol dispensing device may comprise an aerosol valve located at the bottom portion of the aerosol container. The aerosol valve may have a valve stem for displacing the aerosol valve from a biased closed position to an open position upon a movement of the valve stem to discharge the aerosol product from the valve stem. The multidirectional aerosol dispensing device may comprise an undercap having a sidewall extending between a top portion and a bottom portion. The undercap may be mounted to the aerosol container with the top portion of the undercap being adjacent to the bottom portion of the aerosol container. The bottom portion of the undercap may terminate in a base surface for supporting the aerosol dispensing device on a supporting surface to store the aerosol dispensing device in an inverted position. The multidirectional aerosol dispensing device may comprise an actuator lever located adjacent and outboard of the sidewall of said undercap, being movably mounted relative to the undercap and configured to move the valve stem when the actuator lever is moved.
According to various configurations, when the actuator lever is depressed, the bottom surface of the actuator lever may be at an actuator pivot angle of about 3 degrees to about 10 degrees, or from about 4 degrees to about 9 degrees, or from about 5 degrees to about 8 degrees, or from about 5.5 degrees to about 7.5 degrees, out of plane with respect to the base surface of the bottom portion of the undercap. When the actuator lever is depressed, it may displace the valve stem, the valve stem may displace the aerosol valve to the open position, and the spray axis of the valve stem may be at an angle, the dispensing angle, relative to a longitudinal axis 101 of the device. The dispensing angle 103 may be about 0.5 degrees to about 5 degrees, or from about 0.5 degrees to about 4 degrees, or from about 0.5 degrees to about 3 degrees, or from about 1 degree to about 3 degrees.
Various configurations relate to a multidirectional aerosol dispensing device. The multidirectional aerosol dispensing device may comprise an aerosol container extending between a top portion and a bottom portion for containing an aerosol product and an aerosol propellant therein, an aerosol valve located at the bottom portion of the aerosol container, a check valve located adjacent the aerosol valve, a dip tube with a first end extending to and in fluid communication with the top portion of the aerosol container and a second end extending to the bottom portion of the aerosol container, an undercap having a sidewall extending between a top portion and a bottom portion, and an actuator located adjacent (and, optionally, outboard of) the sidewall of said undercap, being movably mounted relative to the undercap and configured to move the valve stem when the actuator is moved.
The check valve may have a first inlet in fluid communication with the second end of the dip tube, a second inlet in fluid communication with aerosol container, and an outlet in fluid communication with the aerosol valve. The aerosol valve may have a valve stem for displacing the aerosol valve from a biased closed position to an open position upon a movement of the valve stem to discharge the aerosol product from the valve stem. The check valve may have a first position when the aerosol container is spatially oriented such that the top portion of the aerosol container is above the bottom portion of the aerosol container and a second position when the aerosol container is spatially oriented such that the top portion of the aerosol container is below the bottom portion of the aerosol container. When the check valve is in the first position the check valve may close the first inlet preventing liquid communication between the first inlet and the dip tube. When the check valve is in the second position the check valve may close the second inlet preventing liquid communication between the second inlet and the aerosol container. The undercap may be mounted to the aerosol container with the top portion of the undercap being adjacent to the bottom portion of the aerosol container. The bottom portion of the undercap may terminate in a base surface for supporting the aerosol dispensing device on a supporting surface to store the aerosol dispensing device in an inverted position.
Various configurations relate to a multidirectional aerosol dispensing device. The multidirectional aerosol dispensing device may comprise an aerosol container extending between a top portion and a bottom portion for containing an aerosol product and an aerosol propellant therein. The multidirectional aerosol dispensing device may comprise an aerosol valve located at the bottom portion of the aerosol container. The aerosol valve may have a valve stem for displacing the aerosol valve from a biased closed position to an open position upon a movement of the valve stem to discharge the aerosol product from the valve stem. The multidirectional aerosol dispensing device may comprise an undercap having a sidewall extending between a top portion and a bottom portion. The undercap may be mounted to the aerosol container with the top portion of the undercap being adjacent to the bottom portion of the aerosol container. The bottom portion of the undercap may terminate in a base surface for supporting the aerosol dispensing device on a supporting surface to store the aerosol dispensing device in an inverted position. The multidirectional aerosol dispensing device may comprise an actuator located adjacent the sidewall of said undercap, being movably mounted relative to the undercap and configured to move the valve stem when the actuator is moved.
Various configurations relate to a method of controlling a pest comprising providing a multidirectional aerosol dispensing device according to any of the configurations described herein and dispensing the aerosol product from the device.
These and other features, aspects, and advantages of various configurations will become better understood with reference to the following description, figures, and claims.
Many aspects of this disclosure can be better understood with reference to the following figures, which provide non-limiting examples of various embodiments.
It should be understood that the various embodiments are not limited to the examples illustrated in the figures.
DETAILED DESCRIPTION Introduction and DefinitionsThis disclosure is written to describe the invention to a person having ordinary skill in the art, who will understand that this disclosure is not limited to the specific examples or embodiments described. The examples and embodiments are single instances of the invention which will make a much larger scope apparent to the person having ordinary skill in the art. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by the person having ordinary skill in the art. It is also to be understood that the terminology used herein is for the purpose of describing examples and embodiments only, and is not intended to be limiting, since the scope of the present disclosure will be limited only by the appended claims.
All the features disclosed in this specification (including any accompanying claims, abstract, and drawings) may be replaced by alternative features serving the same, equivalent, or similar purpose, unless expressly stated otherwise. Thus, unless expressly stated otherwise, each feature disclosed is one example only of a generic series of equivalent or similar features. The examples and embodiments described herein are for illustrative purposes only and that various modifications or changes in light thereof will be suggested to the person having ordinary skill in the art and are to be included within the spirit and purview of this application. Many variations and modifications may be made to the embodiments of the disclosure without departing substantially from the spirit and principles of the disclosure. All such modifications and variations are intended to be included herein within the scope of this disclosure. For example, unless otherwise indicated, the present disclosure is not limited to particular materials, reagents, reaction materials, manufacturing processes, or the like, as such can vary. It is also to be understood that the terminology used herein is for purposes of describing particular embodiments only and is not intended to be limiting. It is also possible in the present disclosure that steps can be executed in different sequence where this is logically possible.
All numeric values are herein assumed to be modified by the term “about,” whether or not explicitly indicated. The term “about” generally refers to a range of numbers that one of skill in the art would consider equivalent to the recited value (for example, having the same function or result). In many instances, the term “about” may include numbers that are rounded to the nearest significant figure.
In everyday usage, indefinite articles (like “a” or “an”) precede countable nouns and noncountable nouns almost never take indefinite articles. It must be noted, therefore, that, as used in this specification and in the claims that follow, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a support” includes a plurality of supports. Particularly when a single countable noun is listed as an element in a claim, this specification will generally use a phrase such as “a single.” For example, “a single support.”
Unless otherwise specified, all percentages indicating the amount of a component in a composition represent a percent by weight of the component based on the total weight of the composition. The term “mol percent” or “mole percent” generally refers to the percentage that the moles of a particular component are of the total moles that are in a mixture. The sum of the mole fractions for each component in a solution is equal to 1.
Where a range of values is provided, it is understood that each intervening value, to the tenth of the unit of the lower limit (unless the context clearly dictates otherwise), between the upper and lower limit of that range, and any other stated or intervening value in that stated range, is encompassed within the disclosure. The upper and lower limits of these smaller ranges may independently be included in the smaller ranges and are also encompassed within the disclosure, subject to any specifically excluded limit in the stated range. Where the stated range includes one or both of the limits, ranges excluding either or both of those included limits are also included in the disclosure.
In this specification and in the claims that follow, reference will be made to a number of terms that shall be defined to have the following meanings unless a contrary intention is apparent.
“Standard temperature and pressure” generally refers to 25° C. and 1 atmosphere. Standard temperature and pressure may also be referred to as “ambient conditions.” Unless indicated otherwise, parts are by weight, temperature is in ° C., and pressure is at or near atmospheric.
“Disposed on” refers to a positional state indicating that one object or material is arranged in a position adjacent to the position of another object or material. The term does not require or exclude the presence of intervening objects, materials, or layers.
“Disposed within” refers to a positional state indicating that one object or material is arranged in a position partially or completely surrounded by another object or material. The term does not require or exclude the presence of intervening objects, materials, or layers.
“Align” or “aligned” or “aligning” means to place or to arrange in a straight line. Aligning edges of substrates, therefore, means arranging the substrates so that the edges in question extend along approximately the same line. It is to be appreciated that aligning edges of substrates can be accomplished in a variety of ways, including placing the substrates one on top of the other or side by side.
“Longitudinal axis” refers to an imaginary line running down the center of a body along its longest dimension.
“Direction of gravity” refers to the orientation or path along which gravity acts on an object or in a given space.
“Downward direction” refers to a direction that is substantially in or aligned with the direction of gravity.
“Upward direction” refers to a direction that is substantially opposed to the direction of gravity.
“Upright orientation” refers to a position or an alignment of an aerosol dispensing device in which the device dispenses an aerosol spray in an upward direction.
“Inverted orientation” refers to a position or an alignment of an aerosol dispensing device in which the device dispenses an aerosol spray in a downward direction.
“Multidirectional” refers to the ability of the can to dispense its contents effectively in various orientations. This includes not only an upright position, an inverted position but also sideways, or at any other angle, without noticeable loss of performance or function. This feature ensures consistent spray output regardless of the device's alignment, providing greater flexibility, targeting accuracy, and convenience to the user.
“Above” refers to a relative position of a first object or a first portion of an object in reference to a second object or a second portion of an object, in which a line extending from the first object toward the second object or from the first portion toward the second portion extends in a downward direction. In such an orientation, the first object is above the second object.
“Below” refers to a relative position of a first object or a first portion of an object in reference to a second object or a second portion of an object, in which a line extending from the first object toward the second object or from the first portion toward the second portion extends in an upward direction. In such an orientation, the first object is below the second object.
“Distal” is used to describe a location or position that is situated farther away from a point of reference or origin.
“Proximal” is used to describe a location or position that is situated closer to a point of reference or origin.
“Top” refers to a portion of an aerosol dispensing device or a component thereof that is distal to a point at which the aerosol spray exists the device. The term “top” is, therefore, most clear when the aerosol dispensing device is in an inverted orientation. Thus, the term “top” as used herein may be replaced with the term “distal” as helpful to improve clarity.
“Bottom” refers to a portion of an aerosol dispensing device or a component thereof that is proximal to a point at which the aerosol spray exists the device. The term “bottom” is, therefore, most clear when the aerosol dispensing device is in an inverted orientation. Thus, the term “bottom” as used herein may be replaced with the term “proximal” as helpful to improve clarity.
The bottom portion 202 of the aerosol container 200 may be adjacent to and may cooperatively engage the top portion 301 of the undercap 300. An aerosol product 210 and an aerosol propellant 212 may be disposed within the aerosol container 200. The aerosol dispensing device 100 is in an inverted orientation 110, such that it is positioned to dispense an aerosol spray comprising the aerosol product 210 in a generally downward direction 111 that substantially aligns with a direction of gravity 112. The aerosol container 200 comprises a wall 203. The wall 203 may comprise a plastic material, such as polyethylene terephthalate (PET), or a metal. PET may be preferred, as it is generally lighter than metal and may make the aerosol device 100 easier to use. The aerosol container 200, preferably at least a portion of the wall 203 of the aerosol container 200, may be transparent or translucent.
In some configurations, wall 203 of aerosol container 200 may comprise one or more design elements including insignia, letters, words, graphics, logos, colors, fonts, shapes, or combinations thereof. In some configurations, the design element(s) may be oriented perpendicular to the longitudinal axis 101 of the device 100 or the design element(s) may run parallel to the longitudinal axis 101 of the device 100. The latter may suggest to a user that the device is intended to be disposed in a downward direction.
In some configurations, a nozzle insert assembly may be disposed within through-hole 350. The nozzle insert assembly may comprise a post and a swirl chamber in fluid communication with one or more tangential inlet ports in fluid communication with exit orifice 224 of the valve stem 223 and an exit orifice of the nozzle insert assembly. The shape, dimensions and number of tangential inlet ports, size and dimensions of the swirl chamber and size of the exit orifice of the insert assembly may be chosen to create spray droplets as described herein.
In some configurations, the aerosol valve may be chosen from a check valve, a bag-on-valve, a vertical standard valve, a female valve, a tilt valve, a slotted valve, or the like.
In some configurations, the aerosol container may comprise a bag-on-valve system and may be devoid of a check valve 240 and/or a dip tube 230 (not shown). Bag-on-valve systems are known in the art.

Various configurations relate to an inverted aerosol dispensing device 100, comprising an aerosol container 200 extending between a top portion 201 and a bottom portion 202 for containing an aerosol product 210 and an aerosol propellant 212 therein. The device 100 may also comprise an aerosol valve 220 located at the bottom portion 202 of the aerosol container 200, wherein the aerosol valve is a check valve 240, and a dip tube 230 with a first end 231 extending to and in fluid communication with the top portion of the aerosol container and a second end 232 extending to the bottom portion 202 of the aerosol container 200. The check valve 240 may have a first inlet 241 in fluid communication with the second end 232 of the dip tube 230, a second inlet 242 in fluid communication with aerosol container 200, and an outlet 243 in fluid communication with the aerosol valve 220. The aerosol valve 220 may have a valve stem 223 for displacing the aerosol valve 220 from a biased closed position 221 to an open position 222 upon a movement of the valve stem 223 to discharge the aerosol product 210 from the valve stem 223. The check valve 240 may have a first position 244 when the aerosol container 200 is spatially oriented such that the top portion 201 of the aerosol container 200 is above the bottom portion 202 of the aerosol container 200 and a second position 245 when the aerosol container 200 is spatially oriented such that the top portion 201 of the aerosol container 200 is below the bottom portion 202 of the aerosol container 200. According to various configurations, when the check valve 240 is in the first position 244 the check valve 240 closes the first inlet 241 preventing liquid communication between the first inlet 241 and the dip tube 230 and when the check valve 240 is in the second position 245 the check valve 240 closes the second inlet 242 preventing liquid communication between the second inlet 242 and the aerosol container 200. The device 100 may also comprise an undercap 300 having a sidewall 310 extending between a top portion 301 and a bottom portion 302. The undercap 300 may be mounted to the aerosol container 100 with the top portion 301 of the undercap 300 being adjacent to the bottom portion 202 of the aerosol container 200. The bottom portion 302 of the undercap 300 may terminate in a base surface 320 for supporting the aerosol dispensing device 100 on a supporting surface 400 to store the aerosol dispensing device 100 in an inverted position 110. The device 100 may also comprise an actuator lever 330 located adjacent and outboard of the sidewall 310 of said undercap 300, being movably mounted relative to the undercap 300 and configured to move the valve stem 223 when the actuator lever 330 is moved. According to various configurations, a rotatable portion 340 of the undercap 300 may be rotatable into a first rotational position 341 relative to the aerosol container 200 for enabling the actuator to move the valve stem 223 upon movement of the actuator lever 330 for discharging the aerosol product 210 from the valve stem 223 in a generally downwardly direction 111. The undercap 300 may be rotatable into a second rotational position 342 relative to the aerosol container 200 for inhibiting the actuator from moving the valve stem 223.
The device 100, according to various configurations, allows the aerosol product 210 to be dispensed when the device 100 is in an upright orientation 109 or in an inverted orientation 110. The device 100 may provide better ergonomics, imparting little strain to a consumer's hand or wrist when dispensing. The actuator lever 330 may be paddle-shaped and may allow a consumer to use a finger or a thumb to actuate. The actuator pivots on a hinge such that the dispensing surface is at about a 6 degree angle (actuator pivot angle 226) relative to the resting plane and biased towards the paddle. This small angle helps consumer aim product. It's small enough to not be noticed by consumer but over a throw distance of about 0.3 m to about 1.5 m, preferably about 0.3 m to about 1 m, helps the consumer aim. More specifically, the device 100, according to various configurations, helps to direct the aerosol product 210 to a desired location, because the valve stem 223 and the exit orifice 224 of the valve stem tilt slightly towards the actuator lever 330, when the device 100 is actuated, thereby creating a substantially unnoticeable but useful bias to better spray a target surface. The device 100 may produce a spray that travels an appropriate distance (about 0.3 m to about 1.5 m, preferably about 0.3 m to about 1 m) so that a consumer can apply the aerosol product 210 to surfaces without bending down or reaching high.
Aerosol Product—CompositionThe aerosol product 210 may comprise a composition, preferably a liquid composition, which may be housed within the aerosol container 200. The container may store from about 50 g to about 500 g, or from about 150 g to about 400 g, or from about 200 g to about 350 g, of the composition. The weight of the aerosol product 210, including the composition, is preferably selected to enable a user to comfortably manipulate and actuate the product with one hand, while providing enough composition to treat one or multiple target areas/surfaces of varying sizes, once or multiple times, e.g., multi-use product (e.g., a multi-use product). The aerosol product 210 may be a consumer use product intended to be sprayed onto a target surface. Non-limiting examples of consumer use products include home care products, such as hard floor cleaners and conditioners, carpet cleaners and conditioners, carpet deodorizers, carpet spot cleaners, window cleaners, fabric refreshing sprays (e.g., for clothing or furniture), hard surface cleaners (e.g., for dishware, sinks, countertops), and air fresheners; car care products, such as upholstery cleaners and conditioners, hard surface cleaners, leather cleaners, carpet cleaners, wheel cleaners, tire cleaners, and automotive glass cleaners; personal care products, such as deodorants, body sprays, foot sprays, and hair sprays; pest control products, such as herbicides, insecticides, insect barrier products, garden insecticides, and animal deterrent sprays. The aerosol products may also be suitable for commercial and/or institutional use.
The composition may have a Brookfield viscosity from about 1 cps to about 300 cps, or from about 1 cps to about 200 cps, or from about 2 cps to about 100 cps, or from about 3 cps to about 50 cps. The Brookfield viscosity may enable the aerosol dispensing device to dispense the composition as droplets. For some products, such as pesticide products, droplets may be preferred, particularly versus a mist, a stream, or a foam. The composition may have a surface tension from about 10 mN/m to about 60 mN/m, or from about 15 mN/m to about 50 mN/m, or from about 18 mN/m to about 40 mN/m, or from about 20 mN/m to about 30 mN/m, or from about 22 mN/m to about 28 mN/m, as measured according to the method described herein. It is believed that droplets may be preferred for delivering a targeted spray (particularly for non-selective herbicide compositions), while also sufficiently covering a target area.
The composition may comprise particles having an intensity mean particle size of from about 2 nm to about 500 nm, or from about 3 nm to about 400 nm, or from about 4 nm to about 100 nm. The composition may comprise particles having an intensity mean particle size of less than about 1 micron, preferably less than about 500 nm. Mean intensity particle size can be measured according to the Particle Size Test Method described hereafter.
The composition may comprise particles having a volume mean particle size ranging from about 1 nm to about 100 nm, or from about 2 nm to about 50 nm, or from about 2 nm to about 25 nm, or from about 2 nm to about 10 nm. The composition may comprise particles having a volume mean particle size of less than about 1 micron, preferably less than about 500 nm. Mean volume particle size can be measured according to the Particle Size Test Method described hereafter. Volume mean particle size may be selected to provide a transparent or translucent composition, as well as to efficiently deliver an active agent to the target surface or area.
As detailed below, in the Spray Droplet Size Test Method, spray droplet volume size distribution measurements comprising Spray D(50) Normalized, Spray D(90) Normalized, and Spray D(2,3) Normalized values are determined using a Malvern Spraytec 2000 laser diffraction spray droplet sizing instrument (supplied by Malvern Instruments, Worcestershire, UK). The composition, when dispensed through the aerosol dispensing device 100, may have a Spray D(90) ranging from about 100 microns to about 900 microns, or from about 125 microns to about 800 microns, or from about 150 microns to about 700 microns. Spray D(90) may be selected to efficiently deliver an active agent to the target surface or area. Also, a Spray D(90) in the disclosed ranges may be perceived as capable of traveling a distance of one or more meters and depositing on a target surface. Particles having a Spray D(90) less than 100 microns may create a spray that is too misty or a spray that does not have sufficient velocity to travel to a target surface. The composition, when dispensed through the aerosol dispensing device 100, may have a Spray D(50) ranging from about 100 microns to about 500 microns, or from about 150 microns to about 400 microns.
The composition, when dispensed through the aerosol dispensing device 100, may have a spray diameter of from about 2 inches (5.08 cm) to about 6 inches (15.24 cm), or from about 3inches (7.62 cm) to about 4.5 inches (11.43 cm), as measured according to the Spray Method described herein.
The composition, when dispensed through the aerosol dispensing device 100, may have a spray force of from about 2 gf to about 16 gf, or from about 4 gf to about 12 gf, or from about 6 gf to about 10 gf, as measured according to the Spray Force Method as described herein.
The composition may have a NTU value less than about 200, or less than about 100, or from about 0.5 to about 50, or from about 1 to about 25. A composition having a NTU value in the disclosed ranges may be perceived by a consumer as being clear, transparent, or translucent, which may connote purity, quality, and/or that the composition is not likely to stain surfaces.
The composition may have a b* value from about 0 to about 15, or from about 0.01 to about 10, or from about 0.05 to about 5, or from about 0.1 to about 3. A composition with a b* value according to the disclosed ranges may be perceived by a consumer as having a colorless appearance, while b* values outside the disclosed ranges, especially b* values greater than 5, may appear yellow to a consumer, which may connote that the composition contains impurities, has degraded, and/or is unsuitable for use.
As noted above, at least a portion of the wall 203 of the aerosol container 200 or the entire wall 203 may be transparent or translucent. A transparent or translucent wall 203 or a transparent or translucent portion thereof (e.g., a window) may allow a user to view the composition inside the container 200, without having to dispense the composition. This may be particularly desirable for compositions having NTU values less than about 200 and/or having b* values from about 0 to about 5.
The aerosol dispensing device may have a spray rate ranging from about 0.5 g/s to about 5 g/s, or from about 0.75 g/s to about 4 g/s, or from about 1.25 g/s to about 3.5 g/s, or from about 1.5 g/s to about 3 g/s. The spray rate may be selected to enable targeted dispensing and delivery of the composition from the aerosol dispensing device, without over-spraying or spraying composition outside the target area. Spray rate can be measured according to ASTM D3069 (2013).
The aerosol container 200 may comprise a propellant 212. Examples of suitable propellants include compressed gasses, such as nitrogen, carbon dioxide, and air; liquidized hydrocarbons, such as butane, isobutate, and propane; hydrofluoro-olefins, and mixtures thereof. The propellant may be selected from the group consisting of nitrogen, carbon dioxide, and mixtures thereof. The aerosol container 200 may have an internal gage pressure of from about 414 kPa to about 1,100 kPa, or from about 600 kPa to about 1,000 kPa, or from about 700 kPa to about 900 kPa.
Preferably, the aerosol product 210 is a pest control product comprising a pest control composition. As used herein, “pest control” means the management of a pest species, including any animal, such as insects and other arthropods, plant, or fungus that adversely impacts human activities or the environment, where management includes controlling, killing, eliminating, repelling, or attracting the pest species. The terms “pest control” and “pesticide” are used interchangeably and it is understood that a composition or an ingredient that has “cidal” activity, e.g., pesticide, insecticide, herbicide, fungicide, may or may not kill and/or eliminate the target pest, e.g., arthropod, insect, weed, or fungus. As used herein, “cide” and “cidal” includes compositions, compounds, components, ingredients, materials, etc., which are effective to kill, remove, destroy, defoliate, exterminate, eradicate, eliminate, etc., a target pest, as well as to retard, regulate, inhibit, prevent, etc., the survival, growth, and/or proliferation of such pest.
Pest control products and compositions may include products and compositions for managing a pest species inside and outside of a building, such as a dwelling or a business, including, but not limited to, areas such as garages, patios, balconies, screened porches, lawns, and/or gardens. Pest control products and compositions may include products and compositions for use in and/or on yards, lawns, bushes, trees, and/or outdoor plants, as well as for use on or around indoor plants. Pest control products and compositions may include selective and non-selective products and compositions, such as selective and non-selective herbicides, fungicides, and insecticides. Pest control products and compositions may also include products and compositions for topical application to humans to control or repel pest species, such as insects and other arthropods.
In particular, the market for weed control products and arthropod pest control products is growing, due to factors such as an increase in urban housing, changes in weather patterns, and an increase in home food gardening and the desire to keep lawns, flower beds, etc. looking neat and attractive. At the same time, there is increasing consumer demand for insecticide and herbicide products that are natural and non-toxic. Consumers also prefer herbicide and insecticide products that contain a limited number of ingredients and/or recognizable ingredients, as communicated by simpler ingredient statements. However, these products are still expected to be efficacious and efficiently control weeds and arthropods, comparable to traditional chemical pesticide products. Also, there are existing herbicide and insecticide products that contain natural ingredients, such as plant essential oils. However, these existing products have a number of disadvantages: some products are messy or difficult to use and some products have limited efficacy.

A sprayed drop of a pesticidal composition comprising an active agent is preferably able to wet a target surface and spread out or cover a target area to perform its intended function. A surfactant generally reduces the surface tension of the water on the surface of the spray drop by reducing the interfacial tension between the spray drop and target surface, e.g., exoskeleton of an arthropod. Surfactants also wet and disperse particles of active ingredient(s) in the composition prior to spraying, thereby enabling more uniform coverage and wetting of the target upon spraying. Surfactants may also function to emulsify active agents that are not easily solubilized in water, such as oils. Surfactants thus include various agents known to function as emulsifiers or wetting agents. Suitable surfactants include anionic surfactants, amphoteric surfactants, zwitterionic surfactants, nonionic surfactants, cationic surfactants, or mixtures thereof.
Anionic surfactants are surfactant compounds that contain a long chain hydrocarbon hydrophobic group in their molecular structure and a hydrophilic group, including salts such as carboxylate, sulfonate, sulfate or phosphate groups. The salts may be sodium, potassium, calcium, magnesium, barium, iron, ammonium, and amine salts of such surfactants. Anionic surfactants include the alkali metal, ammonium and alkanol ammonium salts of organic sulfuric reaction products having in their molecular structure an alkyl or alkaryl group containing from about 8 to about 22 carbon atoms and a sulfonic or sulfuric acid ester group. Examples of such anionic surfactants include water soluble salts and mixtures of salts of alkyl benzene sulfonates having from about 8 to about 22 carbon atoms in the alkyl group (e.g., linear alkyl benzene sulfonates, such as dodecylbenzene sulfonate and salts thereof), alkyl sulfates and alkali metal salts thereof (preferably those having from about 8 to about 22 carbon atoms in the alkyl group, e.g., sodium dodecyl/lauryl sulfate), alkyl ether sulfates having from about 8 to about 22 carbon atoms in the alkyl group and about 2 to about 9 moles of ethylene oxide (e.g., sodium laureth sulfate). Aryl groups generally include one or two rings, alkyl groups generally include from about 8 to about 22 carbon atoms, and ether groups generally comprise from about 1 to about 9 moles of ethylene oxide (EO) and/or propylene oxide (PO), preferably EO. A preferred anionic surfactant is sodium lauryl sulfate or SLS (also known as sodium dodecyl sulfate). The pest control composition may comprise from about 1% to about 10%, preferably from about 2% to about 8.5%, or from about 4% to about 8%, by weight of the composition of sodium lauryl sulfate.

Fatty acids and salts thereof are organic molecules comprising a single carboxylic acid moiety (carboxylate anion in salts) and at least 7 carbon atoms, or from about 11 to about 22 carbon atoms, or from about 12 to about 16 carbon atoms. The salts may be sodium, potassium, calcium, magnesium, barium, iron, ammonium, and amine salts of fatty acids. The salts of fatty acids are also known as soaps. Fatty acid and the salts thereof may be linear, branched, saturated, unsaturated, cyclic, or mixtures thereof.

Some of these compounds are aliphatic derivatives of heterocyclic secondary and tertiary amines, in which the aliphatic substituent(s) may be straight or branched, at least one of the aliphatic substituents contains from about 6 to about 20, or from about 8 to about 18, carbon atoms, and at least one of the aliphatic substituents contains an anionic water-solubilizing group, e.g., carboxy, phosphonate, phosphate, sulfonate, sulfate.
Zwitterionic surfactants are surface active agents having a positive and negative charge in the same molecule, where the molecule is zwitterionic at all pHs. Zwitterionic surfactants include betaines, sultaines, and lecithins. The zwitterionic surfactants generally contain a quaternary ammonium, quaternary phosphonium, or a tertiary sulfonium moiety.

Spray droplet volume size distribution measurements comprising Spray D(50) Normalized, Spray D(90) Normalized, and Spray D(2,3) Normalized values are determined using a Malvern Spraytec 2000 laser diffraction spray droplet sizing instrument (supplied by Malvern Instruments, Worcestershire, UK), equipped with a 300 mm lens possessing a focal length of the 150 mm, and an Air Purge System (not greater than 14.5 psi). The system is controlled with a computer and software accompanying the instrument, such as the Spraytec software version 3.20 or equivalent, utilizing Mie Theory and Fraunhofer Approximation optical theory. The system is placed in a fume hood for atmospheric control with care taken to place it directly opposite the actuation spray plume trajectory to prevent saturation, with an air flow rate of between 50-70 L/min (60 L/min was the target rate). The distance from the dispensing nozzle orifice to the laser during measurements is 30 cm. A new spray bottle is used for each sample replicate analyzed. Lighting conditions are not changed during or between the background control and test sample data collection periods. Light obscuration values below 95% are considered suitable to provide accurate results.
Samples analyzed included “example” samples, which are samples according to this disclosure, and comparative samples. All newly created example samples are tested within three hours of preparation and are measured at temperatures between 20-22° C.

Spray measurements are conducted using the following Spray Procedure: The sample is first test sprayed from the spray bottle for 1-2 seconds, to ensure that the nozzle is free flowing and not clogged; the sample is loaded into the holding device in the front of the Spraytec 2000 system. The actuator is fully depressed. The spray droplet size data are viewed and saved as “Average Scatter Data”.
a. The value obtained from each sample measurement is normalized to the control sample value in accordance with the following calculations:
The value of Spray D(50) Normalized=D(50)Example/D(50) Control;
The value of Spray D(90) Normalized=D(90)Example/D(90) Control;
The value of Spray D(3,2) Normalized=D(3,2)Example/D(3,2) Control;
wherein:
Spray D(50), Spray D(90), and Spray D(3,2) are values obtained from the instrument software for both the example samples and control samples separately.
Each of the Spray D(90) Normalized and Spray D(3,2) Normalized values reported for each of the samples is the average value calculated from five replicate spray plumes per sample.
Determination of the Hunter L.a.b. (CIE) b* ValueThe formation of yellow color is measured using the Hunter L.a.b. (CIE) method. The b* value is determined using a HunterLab ColorFlex EZ® spectrophotometer (HunterLab, 11491 Sunset Hills Road, Reston, Virginia 20190). The methodology that is used is described in detail in the “User's Manual for ColorFlex EZ Version 2.2.”
The HunterLab ColorFlex EZ® spectrophotometer uses a xenon flash lamp to illuminate a sample. The light reflected from the sample is then separated into its component wavelengths through a dispersion grating. The relative intensities of the light at different wavelengths along the visible spectrum (400-700 nm) are then analyzed to produce a number result indicative of the color of the sample.
Turbidity MethodA turbidimeter is used to measure the turbidity of the compositions. This instrument measures the turbidity of liquids in Nephelometric Turbidity Units (NTU). The method of measuring turbidity is described in detail in the following reference: Hach 2100Q and 2100Q is User Manual, Edition 6, August 2021, from the Hach Company. If a sample is not homogenous prior to analysis, the sample is inverted until it appears homogenous and is then poured into an analyte vile for measurement.
This method of measurement determines quantitative values of turbidity by evaluating the ratio of a primary nephelometric light scatter signal to a transmitted light scatter signal. This particular method of evaluation provides values between 0-1000 NTU, where increasing NTU values indicate more turbid compositions. In between each test sample, water controls may be measured to ensure proper equipment operation. For example, water may have a turbidity of about 1.11 NTU and isopropyl alcohol may have a turbidity of about 0.15 NTU. It is believed that improved emulsification of active ingredients, particularly hydrophobic active ingredients, yields lower NTU values.
Surface Tension MethodSurface tension is measured according to ASTM 1331-14 (Published January 2015) using an EZ-Pi tensiometer (Kibron, Parrish, Fla.), or equivalent. The instrument is calibrated according to the manufacturer instructions using DI water. Measurements are taken and values are reported in mN/m.
Temperature Stability MethodSamples are prepared by combining all composition ingredients in a 4-ounce glass vial at ambient conditions (25 deg. C). The sample is mixed and, five minutes after mixing is completed, the sample is observed for initial stability.
Cold temperature cycle stability is measured by filling a 4-ounce glass vial with a sample composition. The vial is sealed and stored at 5° C. for 12 to 14 hours. The vial is then moved to a 25° C. environment and stored for 10 to 12 hours, thereby completing one cold temperature cycle. This is repeated two more times, for a total of three cold temperature cycles. After the final incubation at 25° C., the vials are visually observed for stability (and may be assessed for turbidity and b* value using the Turbidity and Hunter L.a.b. (CIE) method described above).
Spray Force MethodSpray force is measured using a digital force gauge with a 2.5N capacity load cell, for example, an Advanced Force Gauge available from Mecmesin, or equivalent. A plate mounted to a probe with a minimum 6 inch diameter is assembled to the force gauge and is positioned perpendicular to the exit nozzle of the actuator flow path. The sample is placed in a water bath to 22° C. for 5 minutes to normalize the sample to the test environment prior to testing. The sample is then placed at a distance of 12 inches from the probe. The sample is sprayed for three, one second sprays (with a delay between sprays of approximately two seconds). Click the “Start” icon with the start of the first spray. Click the “Stop” icon after the third spray. Take the three peak force measurements and record the average to the nearest 0.01 gf. In like fashion, the procedure is repeated for three replicate test specimens. The average peak among the three replicates is calculated and reported as Spray Force to the nearest gf.
Spray Diameter MethodThe spray pattern may be important as it impacts how easy it is for consumers to spray a pest and how much of the pest control composition is applied to a pest during a spray event. A smaller spray diameter, or more localized spray, may make it difficult for a user to accurately spray the pest. A larger spray diameter, or mistier spray, can result in too much of the composition landing on surface adjacent to the pest rather than the pest. This can lead to a larger mess the consumer may need to clean up. Given the general size of a pest and the distance one can comfortably hold the container away from the pest, a spray diameter of about 2 inches to about 6 inches may be desirable.
Spray diameter is measured using thermal sensitive paper mounted on a rigid test stand. Test samples are equilibrated to 20 to 24° C. The test can is placed perpendicular +/−10° to the paper at a distance of 12 inches. After spray is completed, the test paper is scanned and analyzed with imaging software. The outside diameter of the spray is calculated by:
Where “area” is the cell location in the imaging software containing the outside diameter area
