This application claims priority to U.S. Patent Application No. 62/547,948, entitled “Closure For A Container”, and filed Aug. 21, 2017, which is incorporated by reference herein in its entirety.
TECHNICAL FIELDThe present invention relates generally to a closure for a container of a fluent substance.
BACKGROUND OF THE INVENTION AND TECHNICAL PROBLEMS POSED BY THE PRIOR ARTClosures are employed to selectively prevent or permit communication between the exterior and interior of a container (e.g., bottle, flexible pouch, machine, vessel, etc.) through an opening in the container. A typical closure includes at least (1) a receiving structure (e.g., a body, base, fitment, etc.) arranged at an opening to the container interior, and (2) a closing element (e.g., a lid, cover, cap, etc.) that is cooperatively received by the receiving structure.
The receiving structure of the closure can typically be either (1) a separate structure that can be attached at the container opening, and that defines a passage through the structure for communicating with the container opening and the container interior, or (2) an integral structure that is a unitary portion of the container, and which defines a passage through the structure such that the passage functions as the opening, per se, to the container.
The closing element typically is movable relative to the receiving structure passage between (1) a fully closed position occluding the passage, and (2) an open position at least partially exposing the passage. Some closures may include additional elements (e.g., tamper-evident features, locking elements, etc.).
A closure specifically designed for dispensing a fluent substance may be described as a dispensing closure. Various fluent materials or substances (including oils, lotions, creams, gels, liquids, food items, granules, powders, etc.) may be packaged in a rigid, flexible, or collapsible container having a dispensing closure that can be opened and closed. A flexible container may be pressurized by a user to force the fluent substance from the container and through the closure body to dispense the fluent substance at a target region or onto a target surface area. The container with the closure mounted thereon, and the contents stored therein, may be characterized as a “package.”
One type of closure is typically provided with a closing element in the form of a lid that is hingedly connected with a closure body. A user of such a closure would typically encounter the lid in a closed position. The lid may be provided with a region for being lifted by a user of the closure to rotate the lid with respect to a stationary portion of the closure (e.g., closure body), thus moving the lid from the closed position into an open position such that a fluent substance may be dispensed through the closure.
The inventors of the present invention have noted that such closures, when installed on a container of a fluent substance, may be susceptible to inadvertent opening during shipping or handling, which can result in premature or messy leaking of the fluent substance stored within the container. For example, the closed lid may be accidentally bumped open, or the lid may accidentally open if the inside of the lid is subjected to a sudden impact from the fluent substance or if the internal pressure of the container increases significantly during shipping or storage in high temperature environments. The inventors have found that such premature leakage through a conventional closure may be especially pronounced in an e-commerce scenario, whereby an individual package is shipped and handled in an unconstrained manner and may be subjected to a variety of forces, orientations, and temperatures.
The inadvertent opening of such a closure may be prevented, or at least minimized, by applying an adhesive seal or a film wrap around at least a portion of the closure to mechanically prevent movement of the lid until the seal or wrap has been removed by a user of the closure. However, such additional adhesive seals and film wraps are typically designed and provided for only a “one-time” use (non-reusable) application to withstand lid opening forces during shipping. Moreover, such additional seals or wraps may increase the cost of the closure, require additional manufacturing steps, or present a nuisance to the user who must remove and discard such a seal.
Furthermore, the inventors have found that the inadvertent opening of such a closure may be prevented, or at least minimized, by modifying the existing latching or snap-fit connections of conventional closures to increase the force required to open such latches or connections. However, such modifications may present a nuisance to the user of the closure, who must generate a sufficient force to open such a strengthened latch or connection, and may be injured in the attempt, or may even be unable to open such a strengthened latch or connection altogether.
The inventors of the present invention have determined that it would be desirable to provide a component of the closure that may be separately formed from the closure lid and body, but which is assembled with the lid and the body for preventing inadvertent opening of the closure during shipping or handling. The inventors of the present invention have further found that it would be desirable to provide indicia on such a separately formed component of the closure in a manner that would be amenable to mass production and customization for multiple applications or customers.
The inventors of the present invention have further determined that it would be beneficial to provide a component that is separately formed from the closure lid and body, but which is assembled with the lid and the body in only a single orientation to facilitate repeatable and easy operation thereof by a user.
The inventors of the present invention have also determined that, in many applications, it may be desirable to provide an improved closure as part of a package wherein the closure structure facilitates or accommodates the cleaning of the closure and/or minimizes the potential for accumulation of residue, dirt, grime, etc. during the useful life of the package.
The inventors of the present invention have also determined that it would be desirable to provide an improved closure that cart be configured for use with a container of a fluent substance so as to have one or more of the following advantages: (1) an improved ease of manufacture and/or assembly, and (ii) a reduced cost of manufacture and/or assembly.
The inventors of the present invention have invented a novel structure for a closure for use with a container wherein the closure includes various advantageous features not heretofore taught or contemplated by the prior art.

It should be appreciated that the invention may include any or all of the above-described features, include only one of the above features, more than one of the above features, and any combination of the above features. Furthermore, other objects, features and advantages of the invention will become apparent from a review of the entire specification including the appended claims and drawings.
In the accompanying drawings forming part of the specification, in which like numerals are employed to designate like parts throughout the same,
While this invention is susceptible of embodiment in many different forms, this specification and the accompanying drawings disclose only specific forms as examples of the invention. The invention is not intended to be limited to the embodiments so described, and the scope of the invention will be pointed out in the appended claims.
For ease of description, many figures illustrating the invention show embodiments of a closure in the typical orientation that the closure would have at the opening of a container in the form of an upright bottle, and terms such as “inward”, “outward”, “upper”, “lower”, “axial”, “radial”, “lateral”, etc., are used with reference to this orientation. It will be understood, however, that the closures of this invention may be manufactured, stored, transported, used, and sold in an orientation other than the orientation described and illustrated.
The closures of this invention are especially suitable for use with a variety of conventional or special containers, the details of which, although not fully illustrated or described, would be apparent to those having skill in the art and an understanding of such containers. The particular containers illustrated are not intended to limit the present invention. It will also be understood by those of ordinary skill that novel and non-obvious inventive aspects are embodied in the described closures alone.
The closures described herein are especially suitable for use on a container that contains a fluent material or substance in the form of a lotion or cream that can be dispensed, or otherwise discharged, from the container through the opened closure. Such fluent substances may be, for example, a personal care product, a food product, an industrial product, a household product, or other types of products. Such substances may be for internal or external use by humans or animals, or for other uses (e.g., activities involving medicine, commercial or household maintenance, agriculture, manufacturing, etc.).
A first embodiment of a closure of the present invention, and the components thereof, are illustrated in
It will be understood that the container may be any conventional type, such as a collapsible, flexible pouch, or may be a generally rigid bottle that has somewhat flexible, resilient walls.
The container, or a portion thereof, may be made from a material suitable for the intended application. For example, the container may be a pouch made from a thin, flexible material (wherein such a material could be a polyethylene terephthalate (PET) film or a polyethylene film and/or an aluminum foil). Alternatively, a more rigid container (e.g., a bottle) could be made from a thicker less flexible material such as molded polyethylene, polypropylene, polyethylene terephthalate, polyvinylchloride, glass, or other materials.
In applications wherein the closure is mounted to a container such as a bottle, it is contemplated that typically, after the closure manufacturer would make the closure (e.g., by molding parts of the closure from a thermoplastic polymer and assembling them), the closure manufacturer will then ship the closure to a container filler facility at another location where the container is either manufactured or otherwise provided, and where the container is filled with a product prior to installation of the closure. If the container is a collapsible pouch, then the closure may include a suitable fitment portion that can be attached to the pouch as the pouch is being made and filled, or as the pouch is being made but before the pouch is subsequently filled through the open closure or through open regions of the pouch walls that are later sealed closed.
In the first illustrated embodiment of the closure 40 in
The container 44, per se, does not form a part of the broadest aspects of the present invention. The container may have any suitable configuration.

In other applications, it may be desirable to employ a generally rigid container, and to pressurize the container interior at selected times with a piston or other pressurizing system (not illustrated), or to reduce the exterior ambient pressure so as to suck the material out through the open closure.
In some other applications, the closure 40 may be used with a product containment system or other type of system (not illustrated), where the closure 40 can function to permit or prevent the egress or ingress of substances relative to the system in which the closure 40 is installed.
For example, in some applications it may be desirable to also accommodate filling or refilling of the container 44 with the fluent contents through the opened closure 40 into the container 44.

The inventors have found that this advantageous assembly of the closure body 54, lid 56, and the retainer 60 is especially suited for preventing inadvertent leaks of a fluent substance during the shipping and handling of the closure 40 attached to a container 44 of a fluent substance in the form of a package, such as in e-commerce, whereby the package may be packed in a number of orientations and shipped in a wide variety of parcels that may be subjected to a wide range of impulse forces, vibrations, pressures, temperatures, and changes in orientation.
One method of assembling the components of the closure 40 is next discussed. It will be understood that the method of assembly described herein is illustrative only, and there may be other methods of assembling the components of the closure 40. The closure body 54 and the lid 56 are preferably integrally molded in the configuration shown in
With the lid 56 oriented in the closed position, the bottom end 126 of the retainer 60 is subsequently brought within the recess 88 of the closure body 54 and oriented such that the hook 138 is inserted through the aperture 90 in an unlocked position illustrated in
The detailed operation and function of the closure 40 will next be described with initial reference to

The user may then lift the lid 56, such as by gripping the container 44 while pulling upward on the lid 56, to rotate the lid 56 about the hinge 62 into the open, dispensing position with the dispensing orifice 84 exposed (as illustrated in
The user may grasp and squeeze the flexible, resilient container 44 to partially collapse, or otherwise reduce the internal volume of the container 44, to pressurize the fluent substance contained therein, In some situations, the user may also invert the container 44. In any event, during dispensing of the fluent substance, the fluent substance initially enters into the interior volume of the closure body 54 and exits the closure 40 from the exposed orifice 84.
When the user ceases to squeeze (i.e., pressurize) the container 44, the outward flow of the fluent substance terminates, and the substance may even be sucked back toward the container 44 by a temporary lower pressure within the container 44 (e.g.. if the container has resilient walls that return from a “squeezed in” configuration to the normal, nondeformed configuration). This allows sonic or all of the residual fluent substance within the spout 80 to be forced by the greater ambient air pressure back through the closure 40 and toward the container 44 to help maintain the overall cleanliness of the package.

A second embodiment of a closure according to the present invention is illustrated in
The second embodiment of the closure 40A differs from the first embodiment of the closure 40 in that the second embodiment of the closure 40A is not snap fit onto the container 44A. Rather, a screw thread attachment is used. In particular, and with reference to
The closure body 56A is provided with an exterior wall 71A, a portion of which defines external, concave surfaces or recesses 88A located on either side of an aperture 90A within the exterior wall 71A. The wall 71A defines a lip or internal surface 94A proximate the aperture 90A for engagement with a mating feature on the retainer 60A to maintain the retainer 60A in a locked position, as further discussed below. The recesses 88A are located on either side of an aperture 90A to accommodate a user's finger tips and to assist a user in grasping and rotating the retainer 60A outwardly and upwardly to separate it from the closure body 54A and the lid 56A.
As illustrated in
With reference to
Assembly of the retainer 60A with the closure body 54A and the lid 56A is generally functionally similar to, but substantially reversed with respect to, the assembly of the components of the first illustrated embodiment of the closure 40. Specifically, the retainer 60A is assembled initially with the lid 56A, and then the retainer 60A is assembled with the closure body 54A. The user may insert the top end hook 138A of the retainer 60A into the channel 112A, and then subsequently press the bottom end snap-fit projection 130A through the aperture 90A into the position shown in
Disassembly of the retainer 60A from the closure body 54A and the lid 56A is generally accomplished in an opposite manner as describe immediately above, whereby the user would grasp the retainer 60A by placing a thumb in one of the recesses 88A and a finger in the other of the recesses 88A to grasp the sides of the retainer 60A. The user may then pull outwardly and upwardly on the retainer 60A in a direction away from the closure body 54A. With a sufficient removal force, bottom end the snap-fit bead 134A is urged past the internal closure body surface 94A, moving the snap-fit projection 130A outwardly through the aperture 90A. The retainer 60A may then be rotated away from the closure body 54A and into the unlocked position illustrated in
A third embodiment of a closure according to the present invention is illustrated in
With reference to
The inventors have found that it may be desirable to provide the retainer 60B and the recess 88B within the closure body 54B and the lid 56B with similar shapes that restrict the assembly of the components of the closure 40B to assist a user of the closure 40B to more easily and quickly assemble and/or re-assemble such components. This restriction on assembly of such components may be especially desirable where the retainer 60B is separately formed from the closure body 54B and the lid 56B.
It will be appreciated that in some embodiments, not illustrated, the retainer 60B and the recess 88B may have a variety of shapes and need not be limited to only tapered shapes. Furthermore, the recess 88B may be limited to only one of the closure body 54B or the lid 56B depending on the application and the size and shape of the retainer 60B.
With reference to
The closure manufacturer may thus utilize a greater cavity mold for the closure body 54B and the lid 56B to make the components of the closure 40B that can be shared amongst a variety of customers, bottlers, or fillers, while the closure manufacturer may utilize a lesser cavity mold for each individual customer, bottler, or filler.
A fourth embodiment of a closure according to the present invention is illustrated in

The inventors have found for some applications that it may be desirable to provide the retainer 60D that is unitarily formed with the remaining the components of the closure 40D to prevent the retainer 60B from being lost or discarded by a user of the closure 40D. As with the second embodiment of the closure 40A, in the locked position, the retainer 60D creates a tensile force between the lid 56D and the closure body 54D, which is sufficient to prevent, or at least minimize, the likelihood of inadvertent opening of the lid 56D during shipping or handling of the package or due to pressurization of the package.

The sixth illustrated embodiment of the closure 40E operates in somewhat of a similar manner as discussed above with respect to the fourth illustrated embodiment of the closure 40C, once it is fully assembled, with the exception that in the sixth embodiment of the closure 40E, the retainer 60E has a spring clip and integral hinge features that permit the retainer 60E to be advantageously, separately formed from the lid 56E and the closure body 54E, and then subsequently assembled into the orientation shown in
With reference to
Still referring to
It will be understood that the retainer 60E need not be limited to having a living hinge 126E, and that in other embodiments (not illustrated) other types of hinges or tethers could be used (not illustrated) such that the projections 138E. are generally rotatable or movable relative to the top end 124E of the retainer 60E.
While not presently preferred, it will be understood that the clip feature of the retainer 60E need not be permanently affixed to the closure body 54E when it is assembled therewith, and instead it may be removed by a user or manufacturer.
The inventors have found for sonic applications that it may be desirable to provide a retainer 60E that (i) is separately formed from the remaining the components of the closure 40E (e.g., the closure body 54E and the lid 56E), and (i) is flexible by way of an integral hinge 126E. For example, a closure manufacturer may advantageously utilize a unitarily molded closure body 54E and lid 56E for a variety of customers, bottlers, or fillers—each of which may rewire a different or customized retainer 60E (e.g., customized colors, texture, and/or indicia on the retainer 60E). The closure manufacturer may separately mold the retainer 60E in a different mold, especially one having fewer cavities than that of the common or shared mold for the body 54E and the lid 56E, in order to efficiently and cost-effectively manufacture the inventive closure 40E for a variety of customers.
As with the first embodiment of the closure 40, the retainer 60E of the sixth embodiment of the closure 40E, in the locked position, creates a tensile force between the lid 56E and the closure body 54E, which is sufficient to prevent, or at least minimize, the likelihood of inadvertent opening of the lid 56E during shipping or handling of the package or due to pressurization of the package.
Various modifications and alterations to this invention will become apparent to those skilled in the art without departing from the scope and spirit of this invention. Illustrative embodiments and examples are provided as examples only and are not intended to limit the scope of the present invention.
