DETAILED DESCRIPTION
[0015] An elastic dispensing closure and a related elastic dispensing package are described below with reference to applications for dispensing food condiments, but the presently disclosed closure and package are suitable for dispensing any fluent material, including liquids, fluent solids, semi-solid/semi-liquid materials, and/or the like. The presently disclosed elastic dispensing closure generally includes an inner elastic dispensing element establishing a reservoir configured to hold fluent material supplied from a glass container and an outer closure stand at least partially circumferentially surrounding the dispensing element and configured to support the glass container in an inverted position. The dispensing element is manually squeezable by a user to dispense the fluent material out of the glass container, without having to squeeze the glass container, which, of course, is not elastic because it is rigid. Accordingly, the presently disclosed dispensing closure facilitates provision of dispensing packages including glass containers, or even metal or plastic containers with thick-walled bodies that are configured to be rigid and not elastic upon manual squeezing thereof. Likewise, the container is illustrated and disclosed as a bottle, but the container may be a jar, jug, or any other suitable type of container.
[0016] With specific reference now to the drawing figures,
[0017] The container 12 includes a closed end 16, a sidewall 18 extending away from the closed end 16, and an open end 20 terminating the sidewall. The sidewall 18 may include a neck 22 that may include one or more closure engagement elements 24, for example, one or more threads, lugs, or the like. The container 12 may be composed of glass, ceramic, metal, plastic, or any other material configured as a rigid container, but not as an elastic dispensing container.
[0018] The dispensing closure 14 is configured to be coupled to the open end 20 of the container 12, and includes an inner elastic dispensing element 26, a closure coupling ring 28 coupled to the container 12 to couple the dispensing element 26 to the container 12, and an outer closure stand 30 that may at least partially circumferentially surround the dispensing element 26 and at least a portion of the coupling ring 28. The container 12, the dispensing element 26, and the coupling ring 28 may constitute a dispensing package subassembly apart from the closure stand 30, which may be a component separate from the subassembly. The dispensing element 26 may be composed of rubber, an elastomeric polymer or any other polymeric material, or any other material suitable for use as an elastic dispensing component that, upon manual squeezing, flexes from a rest state an amount sufficient to dispense fluent product out of the 10 package of which such a component is a part and, upon release of the manual squeezing, elastically returns to the rest state. In one example, the dispensing element 26 may be composed of a silicone polymer, or any other elastomeric or polymeric material, or any other material suitable for use as an elastic dispensing component. The coupling ring 28 may be composed of glass, ceramic, plastic or any other polymeric material, metal, or any other material suitable for use in coupling an elastic element to a rigid container. In one example, the coupling ring 28 may be composed of polypropylene. The closure stand 30 may be composed of plastic or any other polymeric material, glass, ceramic, metal, or any other material suitable for use as a package-supporting component that, upon resting of the package 10 in the inverted position of the container 12 as shown, is capable of maintaining the package 10 in such an inverted rest position. In fact, the closure stand 30 even may be composed of an elastomeric material so long as the wall thickness and/or other parameters of the closure stand 30 are configured to maintain the package 10 in the inverted rest position without buckling, collapse, or other such failure of the closure stand 30.
[0019] The dispensing element 26 is illustrated in the form of a bulb, but may take the form of a bellows, or any other configuration suitable for use as an elastic dispensing element. As used herein, the terminology elastic dispensing element includes a product having one or more walls or portions that may be distorted from a rest position to a distorted position by application of a user's manual force to expel fluent material therefrom and that return to the rest position when the force is removed. Notably, the resilience of the element may be internal or inherent to material composition and/or configuration of the element, or may be external or imposed to the element by a spring or any other biasing element (not shown) suitable for use in dispensing any particular fluent material. The dispensing element 26 or at least portions thereof may be formed of an resiliently flexible or elastic material, or the dispensing element 26 may include rigid members connected together by pliant material. The dispensing element 26 has an internal volume that is varied by manually distorting all or a portion of the dispensing element 26, whereby a resulting increase in pressure within the internal volume is used to move the fluent material to be dispensed.
[0020] The dispensing element 26 includes an open end 32 establishing an inlet through which a longitudinal axis A extends, an elastic sidewall 34 extending axially away from the open end 32, circumferentially surrounding the axis A, and establishing a reservoir, and a normally-closed end 36 terminating the sidewall 34 and establishing an outlet. At the open end 32, the dispensing element 26 may include a radially outwardly extending flange 38 that may be trapped between the coupling ring 28 and the container 12. The flange 38 may serve as part of a means for coupling the dispensing element 26 to the container 12 via the coupling element 28, and/or may serve as a means for sealing the dispensing element 26 to the container 12 via the coupling element 28. Although not separately shown, a separate seal, for example, an O-ring, may be used between the dispensing element 26 and the container 12 and/or between the coupling ring 28 and the container 12. At least the sidewall 34 of the dispensing element 26 may have a wall thickness that is less than a wall thickness of the coupling ring 28. The dispensing element 26 may have a major outer diameter, for example, the major outer diameter of the sidewall 34, that may be larger than a minor inner diameter of the open end 20 of the container 12, for instance, a mouth opening of the neck 22. The dispensing element 26 is configured to hold a volume of fluent product therein, and is configured dispense at least a portion of the volume of fluent product through the outlet upon manual compression of the dispensing element 26. The normally-closed end 36 of the element may include a collection well 40 that is stepped down from the sidewall 34, and the outlet may be an aperture, a slit, an intersection of slits, or any other outlet configuration suitable for use in dispensing fluent product therefrom. In any case, the outlet may be openable and closeable, such that when the dispensing element 26 is manually squeezed, the sidewall 34 moves from a relaxed state to a deformed state, for instance, radially inwardly, and the outlet opens to permit fluent material to be actively pumped out of the reservoir of the dispensing element 26. Conversely, when the dispensing element 26 is manually released, the sidewall 34 moves back from the deformed state to the relaxed state. Accordingly, when the dispensing element 26 is manually released, the outlet may close to prevent flow of fluent material out of the reservoir of the dispensing element 26. The dispensing element 26 may constitute one example of a manual pumping means for manually pumping a fluent product flowing from the open end 32 of the dispensing element 26 toward the normally-closed end 36 of the dispensing element 26 and out of the outlet of the normally-closed end 36 of the dispensing element 26.
[0021] The coupling ring 28 includes a base wall 42 engaged with the open end 32 of the container 12, for instance, the flange 38, of the dispensing element 26, and a skirt 44 extending away from the base wall 42. The base wall 42 has a central aperture 46 through which a portion of the dispensing element 26 extends. The skirt 44 has a radially inner surface 48 carrying a container coupling element 50 (or multiple such elements), and a radially outer surface 52 releasably received in the closure stand 30. The radially outer surface 52 may be cylindrical or, as illustrated, may be tapered for easy insertion and removal from the closure stand 30. The container coupling element 50 may include one or more threads, lugs, or the like that cooperate with the one or more closure engagement elements 24 of the container 12.
[0022] The closure stand 30 includes a container support annulus 54, and a radially outer shroud or skirt 56 extending away from the container support annulus 54 and terminating in a package rest surface 58 establishing a rest or support open end 60 of the closure stand 30 on which the dispensing closure 14 is restable in an inverted orientation. The support open end 60 may have a circumference greater than that of the container support annulus 54. The package 10 is restable on the package rest surface 58 of the closure stand 30 in an inverted position of the container 12. The package rest surface 58 extends axially beyond the outlet of the normally-closed end 36 of the dispensing element 26. The container support annulus 54 may include a radially inner surface 62 that may be cylindrical or, as illustrated, may be tapered inwardly for easy receipt and removal of the dispensing subassembly from the closure stand 30. The container support annulus 54 may have a container coupling open end 64, and the open end 32 of the dispensing element 26 is spaced axially away from the container coupling open end 64 of the closure stand 30. The skirt 56 may be cylindrical or, as illustrated, may be tapered outwardly for good stability. The closure stand 30 also may include a radially inner dispensing element container 66, for example, to collect any drips of the fluent material from the dispensing element 26.

The outer skirt 276 may circumscribe a corresponding outer surface of a skirt 256 of the stand 230, for example, in an interference or snap fit arrangement, or may be coupled to the closure stand 230 in any other suitable manner. The cover 272 may be unitary with the rest of the closure, for example, connected via an integral living hinge, or, as illustrated, may be a separate component that may be snap-fit or coupled in any other suitable manner to the rest of the dispensing closure 270. The base wall 274 of the cover 272 may establish a planar rest surface on which the dispensing closure 270 is restable in an inverted orientation, or a rest surface 258 of the skirt 256 may establish the rest surface and a support open end 260 when a cover is not used. The other embodiments disclosed herein also may include a cover.
[0030] Additionally, the elastic dispensing closure 270 may include a valve 271 that may be coupled to the dispensing element 226 to establish the normally-closed end 236. The valve 271 may include an elastic component which may be interference fit to the dispensing element 226, molded thereto or therewith, or coupled thereto in any other suitable manner. In any case, the valve 271 may include elastic petals that flex outwardly upon a desired pressure to open the normally-closed end 236 to allow fluent product to flow outwardly and, upon release of the desired pressure, flex inwardly to close and block flow of fluent product.
