FIELD OF THE INVENTIONThe present invention is directed to a refillable container to be used with a laundry cleaner mix. More specifically, the present invention is directed to a refillable container for use with a laundry cleaner bottle closure (cap) containing a laundry cleaner mix to be diluted within the refillable container.
BACKGROUND OF THE INVENTIONOver the past 50 years, laundry cleaner packaging and formulations have changed significantly, with predominately powdered cleaners in cardboard boxes replaced by liquid formulations in plastic containers. While the liquid formulations work well in cold water, and solve prior issues with powder clumping and inadequate dissolution in cold water, liquids pose their own problems. With the liquid formulations comprising significant amounts of water, the packages are large and heavy, necessitating high transportation costs. Further, the liquid detergent packages require relatively large volumes of display space at stores, and commensurate storage after purchase by consumers. Additionally, the move from paper to predominantly plastic containers has resulted in recycling issues; whereas paper recycling, including cardboard, is widely available, plastic recycling remains limited, with plastic often ending up in landfills.
A recent move to more concentrated liquid laundry cleaners addresses plastic container volume, weight, and shelf space. The more concentrated liquids require relatively small amounts of laundry cleaner per wash load, allowing consumers to make smaller volume and weight purchases. Smaller containers allow transportation of a larger number of units of laundry cleaner, with less store display and storage space required per container. However, the move to concentrates has not solved the issue around plastic container recycling; concentrated cleaners remain in plastic containers, with only limited recycling available in the US.
In addition, the move to concentrates has led to a new problem—overuse of laundry cleaner, with fabrics that retain residual soap even after rinsing. This is a logical outcome from the use of concentrates; their measurement becomes more critical as the water content in the concentrate is reduced. Laundry cleaner measurement caps may not be designed to permit accurate cleaner measurement; if one simply fills the cap with cleaner, one may be using two or more times the required amount of detergent/cleaner product in the laundry. This results in overuse of laundry cleaner, more cost per load of laundry, and residual detergent/cleaner product remaining in the laundered items. Removal of the residual detergent/cleaner product through the addition of a secondary rinse cycle adds cost to the load of laundry. Retention of the laundry cleaner in the washed articles can impact human comfort and health through increased cases of skin rashes, allergies due to the cleaning product, and general discomfort from contact with the chemicals retained in the fabrics.
Laundry cleaner containers that may be reused through introduction of a concentrated liquid laundry detergent formulation that is diluted through the addition of water have been described in the literature.
U.S. Pat. No. 4,024,952, “SCREW CAP FOR A CONTAINER,” filed Oct. 3, 1975, discloses a container with a screw cap having a separate compartment for holding a liquid or powdery composition. “The compartment comprises a wall which engages with the inner side of the screwed sleeve of the container and a bottom section which is connected to the cap in such a manner that in opening the container the bottom section releases the contents of the compartment. The bottom section may be a disc which abuts against the lower edge of the wall of the compartment and which is connected to the cap.” The embodiments of the invention detail the compartment with its bottom section, wherein the bottom section of the compartment is released through a mechanical interaction with the cap and neck of the container. The bottom section falls into the bottle while releasing the mix into one or more diluents in the bottle. The cap and compartment embodiments comprise at least 3 separate parts including threaded portions that mate as well as other portions that are press-fit to hold the compartment and its bottom section in place so to retain the laundry cleaner concentrate. With portions of the compartment retained in the cap after release of the concentrate, the cap is not useful for subsequent measurement of the mixed laundry cleaner. In addition, the bottom of the compartment is retained in the laundry cleaner container and may be released into the wash load during pouring.
U.S. Pat. No. 4,088,246, “CAPSULE AND CONTAINER THEREFOR,” discloses a capsule that contains a concentrate substance where the capsule has “a ring or doughnut shaped cross sectional configuration with an annular concentrate storage compartment and a central passageway. The bottom wall of the capsule is of a frangible material and thickness adapted to be pierced or ruptured by puncturing means in or on the container in response to a downward force applied to the capsule while it is in place on the cradle and resting on the puncturing means.” The capsule is separate from other portions of the container in which it is placed and is not a part of the closure of the container. The capsule is required to be pierced so to release the contents into a container. The invention does not disclose how shredded portions of the capsule are retained so not to fall into the larger container. The capsule is separate from any cap or other closure used on the container and is not housed in the cap.
U.S. Pat. No. 4,793,475, “CLOSURE CAPS FOR TWO-COMPONENT PACKAGING SYSTEMS,” discloses a means to contain and introduce a component into a diluent using a “closure cap” with an “inner container”. The inner container may include a base that is severed mechanically so to introduce the component into the diluent. Otherwise, the inner container may have means to be disengaged from the closure cap so that the container and its component fall into the diluent. The patent is silent on use of the closure cap alone to house the component that is intended to be introduced into the diluent. Further, because the closure cap incorporates all, or parts of, the inner container, it is not useful as a measuring means to measure the mixture of the component and diluents for use. The necessity of some portion or all of the inner container to fall into the diluent is not remedied by this art.
U.S. Pat. No. 5,836,479, “RECHARGEABLE CONTAINERS AND DISPENSERS” describes the use of a chemical reservoir that contains a concentrated liquid solution that is introduced to a diluent in a container. The concentrated solution is released from the chemical reservoir by puncturing a sealing membrane after the reservoir is attached to the container. A bottom wall portion of the chemical reservoir may also break away and drop into the container. The chemical reservoir is not disclosed to be useful as a measuring apparatus; it is most frequently used to contain multiple doses of the chemical concentrate so that the container can be recharged multiple times from a single reservoir assembly. The invention does not address means to introduce the chemical concentrate from a reservoir beyond puncturing or breaking portions of the reservoir.
U.S. Pat. No. 6,375,041, “RECHARGEABLE DISPENSING DEVICE,” describes a “rechargeable dispenser including a cap removably connected to a bottle having an upwardly extending flange. The cap is provided with at least one reservoir to be compromised by the spout of the bottle to release chemical concentrate in the bottle for charging the rechargeable dispenser when mixed with a diluent such as water within the bottle. A preferred method of marketing the rechargeable dispenser would be to shrinkwrap or blister pack caps containing chemical concentrate for use with the rechargeable dispenser”. In this invention, the chemical concentrate is enclosed within the cap using plastic materials that are torn and breached through a puncturing and ripping by a spout of the rechargeable bottle. This ripping and puncturing of the plastic material has several disadvantages. The ripped and punctured plastic material is retained in place between the rechargeable dispenser and the cap so that the opening to the cap would be at least partially obstructed by the retained ripped and punctured plastic material. The retention of the ripped and punctured plastic material at the opening of the cap makes it impossible to readily use the cap as a measuring apparatus to measure the amount of diluted solution to be dispensed. Further, the ripped and punctured plastic materials may fall into the rechargeable dispenser during use, and be introduced into the laundry during washing. The ripped and punctured plastic materials, when introduced into the laundry could adhere to laundry items, may enter the plumbing system of the laundry machine where they could impede water flow, or may otherwise negatively impact the washing of the laundry. U.S. Pat. No. 6,375,041 is silent with respect to means to solve these problems.
U.S. Pat. No. 7,854,104, “MULTI-CHAMBER CONTAINER AND CAP THEREFOR,” discloses “a device and means to add a selected component to a main package or chamber. It forms a two-chamber container that keeps the first component separated from the main component, in an air tight sealed manner until a selected time before use. If the first component is moisture sensitive, means are provided to include desiccant granules in the housing that contains the first component.” In specific, the device comprises a cap or delivery package that is mounted on a threaded neck of a container (bottle) main body that contains the main component, preferably a liquid. The cap or delivery package includes a means to push a plunger through the cap or delivery package so to mechanically unseal a bottom surface of the delivery package, releasing a chemical component into the main package (bottle). This invention removes the need to cut, puncture, rip or otherwise dislodge a bottom surface of the cap or delivery package; it does not provide a means to use the cap or delivery package as a measuring apparatus. The cap or delivery package retains the bottom surface after the component has been released into the container (bottle) and would, accordingly, make the cap or delivery package unable to be used as a means to measure the mixed product for use.
The articles and methods disclosed above provide means to introduce one or more components into a diluent housed in a container or bottle. In all cases, the component to be introduced is housed in a delivery package, reservoir, or other holder that includes an integrated membrane or bottom portion that needs to be mechanically cut, ripped, mechanically removed or opened so to introduce the component into the bottle or container. This cutting, ripping, mechanical removal, or opening is done with the delivery package, reservoir, or other holder attached to or housed within the bottle or container. The bottle caps, closures, reservoirs, and delivery packages include mechanical features that preclude their use as a measuring apparatus for determining an amount of mixed solution to be dispensed. The ripped portions remain mechanically attached to one or more portions of the cap or bottle and container. In some examples, the mechanically ripped portions may fall into the bottle or container where they mix with the laundry cleaning solution. The mechanically ripped portions may, therefore, be incorporated into the laundry when the laundry cleaning solution is added to a wash load.
A refillable laundry cleaner container, laundry cleaner mix, refilling method, and laundry cleaner closure (cap) that holds the mix are presented here that address the problems noted above. The formulations of the laundry cleaner mix span all-natural compositions as well as those incorporating manmade cleaning agents, stabilizers, and other constituents. Laundry cleaner bottle closures (caps) that house the laundry cleaner mix are designed to protect the mix from humidity, crushing, and leakage prior to use with the refillable laundry cleaner container.
Problem to be SolvedThere remains an unmet need for a laundry cleaner formulation that is available to consumers, has good cleaning power in cold water, and has a container that can be reused and/or recycled. In addition, there remains a need for a lightweight refillable laundry cleaner container that is easy to shake and to use for pouring, especially for individuals who experience pain and stiffness in their hands. There also remains a need for a refillable laundry cleaner container to be used with a laundry cleaner mix wherein introduction of the mix into the laundry cleaner container does not require mechanical puncturing, ripping, tearing, or shredding of one or more portions of the laundry cleaner container or cap.
In addition, there is an unmet need for a laundry cleaner mix that is packaged in such a way that the user does not contact the mix prior to or during introduction of the mix into one or more diluents. There also remains a need for a laundry cleaner mix that is provided in a tamper-proof and child-proof container.
Yet further, there remains a need for a refillable container that includes a means to promote the mixture of the laundry cleaner mix into the one or more diluents held within the bottle of the refillable container.
Additionally, there remains a need for a refillable container that includes a means to break up clumps or gels of the liquid laundry cleaner that result from the introduction of the laundry cleaner mix into the one or more diluents.
SUMMARY OF THE INVENTIONThe current invention relates to a refillable container including a bottle, and a cap, where the cap has at least one internal cavity to contain a laundry cleaner mix, with the cap including an inner seal comprising a water dissolvable material.
The invention also relates to a cap that has at least one internal cavity to contain a laundry cleaner mix, with the cap including an inner seal comprising a water dissolvable material. The cap may further include an external seal that protects the inner seal and laundry cleaner mix from moisture. One or more caps that house laundry cleaner mix may be packaged as a single unit for sale. Caps may be used with any bottle or container of the desired size, where the bottle or container includes threads or other connection means by which a cap may be attached to the bottle or container.
The invention further relates to a refillable container including a bottle, and a cap, where the cap has at least one internal cavity to contain a laundry cleaner mix, with the cap including an inner seal comprising a water dissolvable material, and an external seal that protects the inner seal and laundry cleaner mix from moisture.
The invention further includes a cap, wherein the cap has at least one internal cavity to contain a laundry cleaner mix, with the cap including an inner seal comprising a water dissolvable material, and an external seal that provides a child-proof and tamper-proof layer.
The invention also relates to a refillable container including a bottle, and a cap, where the cap includes an inner seal of a water dissolvable material that is comprised of paper-making fibers, where the water dissolvable material dissolves or disintegrates when in direct contact with watery fluids.
Further, the invention relates to a refillable container including a bottle, and a cap, where the bottle comprises a base, a mid-section or grasping-section, and a neck portion.
Yet further, the invention relates to a refillable container including a bottle, and a cap, where the diameter at the mid-section or grasping-section is sized to allow grasping by encircling the bottle with one hand. In an exemplary embodiment, the refillable container includes a bottle having a taper in the bottle diameter that provides a narrower region in the mid-section of the bottle that is especially convenient for grasping.
In an exemplary embodiment, the laundry cleaner mix that is used with the refillable container and cap is comprised of powdered ingredients that, when introduced to one or more diluents in the refillable container, dissolve upon shaking. However, liquid mixes can also be used.
Yet further, the invention relates to a method of use of a refillable container including a cap that holds a laundry cleaner mix and includes an inner seal of water dissolvable material, wherein one or more diluents are poured into the bottle of the refillable container, the cap is attached to the bottle, and the bottle is shaken, with the laundry cleaner mix released into the one or more diluents when the one or more diluents contact the inner seal, dissolving the inner seal.
Advantageous Effect of the InventionThe present invention includes several advantages, not all of which are incorporated in a single embodiment. The invention provides a refillable container, and a cap, with the refillable container including a bottle and mixer, wherein the cap contains a laundry cleaner mix that is readily introduced to one or more liquid diluents in the bottle. The packaging used to retain the laundry cleaner mix in the cap allows the mix to be introduced to the diluent(s) in the bottle simply by shaking the refillable container holding the diluent(s) with the cap screwed in place. The user does not contact the laundry cleaner mix, does not measure the mix, and does not have to pour the mix into the bottle.
Further, the one or more sealing layers that are incorporated into the cap serve to protect the laundry cleaner mix from moisture and also provide both tamper-proof and child-proof packaging.
Yet further, the invention provides a bottle that is designed to afford ease of handling, with a tapered shape that includes a region of the bottle that may be grasped readily and may afford ease of shaking and pouring. Additionally, the invention provides a refillable container that is sufficiently compact that it may be readily transported in pouches, holders, and other pocket-features found in bags and back-packs. This provides ease of transport to and from laundry cleaning facilities and rooms.
Further, the invention provides a refillable container and cap that are lighter in weight than laundry cleaner packaging currently known in the art. The incorporation of a laundry cleaner mix, in place of a pre-mixed liquid laundry cleaner, makes the packaging lighter in weight, as it eliminates the water and other diluents commonly found in liquid laundry cleaners today. This leads to reduced shipping costs.
Yet further, the cap with laundry cleaner mix provides a means for a user to refill their refillable container with liquid laundry cleaner through purchase of a relatively small volume package comprising the cap with laundry cleaner mix. As the refillable container is reused, the user purchases only the caps with the laundry cleaner mix incorporated in the volume of the cap. This reduces packaging purchased by the user, reduces shipping costs for the laundry cleaner, and also allows for much more efficient use of store shelf space, where the laundry cleaner mix is sold. In addition, the inventive compact packaging provided herein can be reused and/or recycled, with little waste.
In the following detailed description, for purposes of explanation and not limitation, exemplary embodiments disclosing specific details are set forth in order to provide a thorough understanding of the claimed invention. However, it will be apparent to one having ordinary skill in the art having had the benefit of the present disclosure, that the claimed invention may be practiced in other embodiments that depart from the specific details disclosed herein. Moreover, descriptions of well-known devices, methods and materials may be omitted so as to not obscure the description of the claimed invention.
The present invention relates to a laundry cleaner product, including a ready-to-mix laundry cleaner mix, a cap (closure) that contains the laundry cleaner mix, and a refillable container that mates with the cap (closure). Throughout the description of the present invention, the words “cap” and “closure” are used interchangeably. The cap serves to seal the bottle as well as to hold a mix that is used to make the liquid laundry cleaner. In addition, the cap may be used to measure liquid laundry cleaner for use, following the incorporation of the mix into one or more liquid diluents introduced into the refillable container. The refillable container is used to hold the one or more diluents that interact with features of the cap so that the laundry cleaner mix is introduced into the refillable container. The diluent(s) and mix are shaken to dissolve the mix into the diluents(s), yielding a volume of liquid laundry cleaner that is housed within the refillable container. When the liquid laundry cleaner is exhausted from the refillable container, the refillable container can be reused with a new cap of laundry cleaner mix. Further disclosed is a laundry cleaner mix, comprising premeasured constituents packaged in the cap (closure). The laundry cleaner mix is further described in the co-pending US 20120031804, filed Jul. 29, 2011, entitled “Laundry cleaning product” and incorporated herein by reference.

The water dissolvable material used to make inner seal 133 is preferably in the form of a film. Suitable materials for the film include polyvinyl alcohol and partially hydrolyzed polyvinyl acetate and alginates that dissolve when in direct contact with watery fluids. Such materials are disclosed in U.S. Pat. No. 6,037,319, and incorporated herein by reference. Alternative polymer films that are known to dissolve in water and may be used for the inner seal 133 are disclosed in U.S. Pat. No. 3,277,009, incorporated herein by reference.
The water dissolvable material used to make inner seal 133 may preferentially be comprised of a papery material including paper making fibers wherein the papery material dissolves or disintegrates when in direct contact with watery fluids. Such papery materials include those made by the method described in U.S. Pat. No. 3,431,166, incorporated herein by reference. A water dissolvable paper with adhesive is further described in US 2009/0226116, incorporated herein by reference. Such materials have been shown to dissolve very rapidly and completely when exposed to water, making them the preferred candidate materials for the inner seal 133 of the cap 130. Other water dissolvable materials are contemplated that may include food grade films.
While the cap 130 is illustrated with one inner seal 133, it is within the scope of this invention that more than one inner cavity (or chamber) 131 may be incorporated into the cap 130, whereby more than one inner seal 133 would be incorporated to seal each of the inner cavities. Multiple chambers or cavities for powder may be achieved through the incorporation of several different inner rims and inner seals, with each inner seal being made from a material that dissolves when it encounters a liquid diluents.
The cap 130 further may include an external seal 135 that is adhesively attached to the outer rim 136 of the cap. The external seal 135 comprises a film material that protects the inner seal(s) 133 and laundry cleaner mix from moisture. The external seal 135 may include a pull tab or other mechanical feature that facilitates removal of the external seal from the cap 130. The external seal 135 illustrated in
The cap 130 includes threads used to mate the cap 130 with the refillable container. Preferentially the threads are external threads 134; internal threads are not preferred as they might hinder attachment of the inner seal 133 to the inner rim 132 of the cap 130.

The cap 230 is shown in further detail in
The water dissolvable material used to make inner seal 233 may preferentially be comprised of a papery material comprising paper-making fibers wherein the papery material dissolves or disintegrates when in direct contact with watery fluids. Such papery materials include those made by the method described in U.S. Pat. No. 3,431,166, incorporated herein by reference. A water dissolvable paper with adhesive is further described in US 2009/0226116, incorporated herein by reference. Such materials have been shown to dissolve very rapidly and completely when exposed to water, making them the preferred candidate materials for the inner seal 233 of the cap 230.
The cap 230 further includes an external seal 235 that is adhesively attached to the outer rim 236 of the cap. The external seal 235 comprises a film material that protects the inner seal 233 and laundry cleaner mix 240 from moisture. The external seal 235 may include a pull tab or other mechanical feature that facilitates removal of the external seal 235 from the cap. The external seal 235 may be formed from plastic, paper, and/or metallic films. Preferentially, the external seal 235 includes a thin metal film layer to provide a moisture resistant and protective layer. Further, the external seal 235 may include a heat seal layer that affixes the external seal 235 to the cap 230. The attachment of the external seal 235 to the cap 230 may be done using induction heating, although other methods know in the art may be employed. Both the external seal 235 and inner seal 233 provide tamper resistant and child proof packaging of the laundry cleaner mix 240, housed within the inner cavity 231 of the cap 230.
The mixer 220 is depicted in several views in
The perforations 223 in the mixer 220 have a small dimension that may be smaller than ½ inch, and more preferably smaller than ¼ inch. Most preferably, the perforations 223 in the mixer 220 have a small dimension that is about ⅛ inch. The perforations 223 in the mixer 220 are provided to assist in mixing the diluents(s) and laundry cleaner mix by shaking or otherwise agitating the refillable container 200. The perforations 223 assist in breaking up clumps of mix as the diluent(s) and mix are shaken. Additionally, the perforations 223 are provided to break up gels that may form in the liquid laundry cleaner mixture; again, shaking of the refillable container will assist in breaking up any gels or lumps via interaction of these with the perforations in the shaker. The mixer provides a means to break up clumps or gels of the liquid laundry cleaner that result from the introduction of the laundry cleaner mix into the one or more diluents. The perforations may be made using a variety of shapes including, but not limited to, circles, squares, stars, teardrops, ovals, and mixtures of such shapes. Shapes with sharp corners such as stars, squares, rectangles, and other angular geometric shapes may be preferred for use with mixing the laundry cleaner mix and one or more diluents by shaking. Interior surfaces of the refillable container may be textured so to facilitate mixing, with surface roughness imparted by molding and/or by inclusions in the surface of the refillable container.

Alternatively, the bottle 210 may comprise commercially available bottles such as milk jugs, soda bottles, other beverage containers, containers designed to house prepared sauces, dressings, and other pourable liquid and solid materials, so long as the bottle 210 includes a means by which it may be attached to the cap 230.
While the bottles and caps of the present invention may be packaged in a container allowing them to be sold together, it is envisioned that one or more caps with laundry cleaner mix and one or more seals may be packaged into a container allowing them to be sold singly or in a multi-cap purchase. A cap may be colored or otherwise labeled to indicate the type of formulation that is contained within the cap.
EXAMPLESThe following examples are provided to illustrate the invention. In the following, embodiments of the refillable container and cap are provided. In addition, example laundry cleaner mixes are detailed that may be used with the refillable containers and caps. Further, methods of use of the refillable containers and caps with the example laundry cleaners are detailed. The examples are not exhaustive; they may be modified to allow for refillable containers of other sizes, alternative dilutions of the laundry cleaner mix, various water dissolvable materials to be used in the cap, and other means to provide an external seal to the cap. Alternative formulations for the concentrated laundry cleaner mix, known to those skilled in the art, may also be used with the inventive refillable container and cap.
Example 1An example refillable container with cap was designed and models constructed according to the refillable container and cap descriptions of
The refillable container includes the mixer, which is snap fit into the bottle. The mixer includes perforations through which the diluent(s), laundry cleaner mix, and the resulting laundry cleaner may flow. The perforations in the mixer have a small dimension that is about ⅛ inch.
The cap (closure) of the bottle of this example is sized to hold about ½ cup of liquid laundry cleaner. The cap of this example is approximately cylindrical in shape, having a nominally 2.5 inch diameter circular opening and a height of about 1.5 inches. The cap size is sufficient for the laundry cleaner mix to fit into the internal cavity. The cap includes an inner rim to which a water dissolvable film is applied after the laundry cleaner mix is loaded into the cap. The cap also includes an external rim to which a water impermeable external seal may be applied.
The cap includes external threads that are designed to mate with the internal threads of the mixer. When the cap is screwed into the mixer portion, the height of the refillable container from the base of the bottle, to the top of the cap, is about 9 inches. This size of refillable container with cap is especially convenient for carrying or otherwise transporting the refillable container of laundry cleaner to a laundry room or other location suitable for cleaning laundry. The height and diameter of the bottle allow it to be carried in a pouch or other type of pocket that may be incorporated into a back-pack or bag. This makes the refillable container of this example to be especially convenient for students and other people who might use a common laundry facility at a site of some distance from their living quarters.
Example 2A second example refillable container with cap was designed and models constructed according to the refillable container and cap descriptions of
The refillable container of this example includes the mixer, which is snap fit into the bottle. The mixer of this example, as illustrated in
The cap (closure) of the bottle is sized to hold about ½ cup of liquid laundry cleaner. The cap of this example is approximately cylindrical in shape, having a nominally 2.5 inch diameter circular opening and a height of about 1.5 inches. The cap size is sufficient for the laundry cleaner mix to fit into the internal cavity. The cap includes an inner rim to which a water dissolvable film is applied after the laundry cleaner mix is loaded into the cap. The cap also includes an external rim to which a water impermeable external seal may be applied.
The cap includes external threads that are designed to mate with the internal threads of the mixer. When the cap is screwed into the mixer portion, the height of the refillable container from the base of the bottle, to the top of the cap, is about 10-11 inches.
Example 3 Laundry Cleaner MixIn order to practically implement the refillable container and cap according to the present invention, it is important that the laundry cleaner mix be of the proper volume to fit inside the cap, and be readily mixed upon shaking with one or more diluents in the refillable container. In this example, a laundry cleaner mix is disclosed, comprised of powdered ingredients that, when introduced to one or more diluents in the refillable container, dissolve upon shaking. The quantities of ingredients provided in this example are sufficient to be used with a half-gallon of diluent. If a quart of final product is desired, the quantity of each of the ingredients should be divided by 2. Other volumes of diluent can be used, so long as the quantity of each of the ingredients is appropriately scaled.
Ingredients:
⅛ cup powdered soap (preferably unscented)
⅛ cup washing soda
⅛ cup of Borax
These dry ingredients are introduced into the cavity of the cap (closure), and may be leveled prior to sealing of the cap. Following introduction of the dry ingredients into the cap, the cap is sealed with a water dissolvable layer adhesively attached to an inner rim of the cap.
Having thus described several embodiments of the claimed invention, it will be apparent to those skilled in the art that the foregoing detailed disclosure is intended to be presented by way of example only, and is not limiting.
