Patent Application

This disclosure relates generally to a device for supporting inverted containers to facilitate the removal of liquids from the containers. More specifically, the disclosed device is conformable to accommodate a variety of different sized and shaped containers and collapsible to be easily and conveniently stored when not in use. It is particularly well suited to facilitate draining the viscous remnants of common consumer products that are slow or difficult to dispense as the container is depleted.
The most relevant prior art to the disclosed device includes U.S. Publication No. 2011/028457 to McElligott et al. which describes a collapsible cup having a base and a series of cylindrical body segments that together form a rigid cup body. In its embodiment most relevant to the instantly disclosed device, the McElligott et al. collapsible cup is threaded for its support and adjustability and thus bears no structural resemblance to the device disclosed herein. U.S. Pat. No. 3,434,589, which issued to Valtri et al. on Mar. 25, 1969, describes a compressible-expandable cup having an annular wall, alternately increasing and decreasing diametrically, forming accordion-like folds and means for retaining the cup in a fully compressed form until removed, whereupon the cup springs to an uncompressed predetermined height. Clearly, the relevant prior art is clever and interesting but unrelated to the device disclosed herein.
Specifically, and with deliberate particularity, the device set forth and described herein is an aid in draining the contents, typically viscous remnants, from a container. More specifically, the described device supports and permits the suspension of an inverted container for the purpose of allowing the container to drain or empty as completely as desired. Essentially, the device comprises a top member, at the upper end of the device, having a centrally positioned flexible orifice to accommodate variously-sized inverted containers and a flexible wall member. Preferably, in addition to the top and flexible wall members, the device employs an annular base member, at the lower end of the device, to lend structural support and stability to the device.
So, between and attached to both the base member and the top member is a flexible wall member having a plurality of annular segments, each segment increasing in circumference from said upper-end to said lower-end and each segment defined by a plurality of annular creases allowing inward folds and each segment having a plurality of annular creases allowing inward and outward folds within said segments, said creases and folds thus permitting each segment to fold and collapse within the circumference of the adjacent larger segment or unfold and extend from the adjacent larger segment.
Also described for the edification of all is the method of using the instantly disclosed device to effect the removal of remnants, dregs and diminished contents from an inverted container safely and securely suspended over a receptacle sized for the receipt of drained contents.
A complete appreciation of the disclosed device is facilitated by referring to the accompanying drawing. Referring initially to
Referring again to
To continue with the description of the disclosed device 10, return to
Positioned between the top member 14 and the base member 12 of the device 10 is flexible wall member 18. The wall member comprises a plurality of segments X, Y and Z. Each segment is defined by at least one major collapsing crease: A, B and C. As currently configured, segment X is defined by major collapsing creases A and B, segment Y is defined by major collapsing creases B and C and segment Z is defined by major collapsing crease C and the bottom of the wall member 18. In other words, the terminus of segment Z is the bottom of the device. The major collapsing creases fold inward toward the center of the device and, appropriately enough, allow the top member 14 and segments X and Y of the device to collapse within the circumference or confines of the larger adjacent segment of the device.
Within each segment are a plurality of folding creases. Within segment X are folding creases m, n and o. Within segment Y are folding creases p, q and r. And, within segment Z are folding creases s, t and u. The folding creases permit the segments to fold approximately in half and allow for the collapse of the segments along the collapsing creases.
In
The device 10 can be further reduced in height by urging major collapsing crease B to fold inward which permits folding creases p, q, and r to enable crease q to fold and extend outward, thus allowing segment X and top member 14 to collapse within segment Y. For purposes of clarity, it is not mandatory that top member 14 accompany the collapse of segment X into segment Y, but if there is justification for denying the collapse of the top member, or any other smaller segment during height reduction of the device 10, the top member and any smaller segments can be easily re-extended.
And, finally, if complete reduction of the height of the device is desired as for purposes of storage, the combination of the top member 14, segment X and segment Y can be collapsed within the circumference or confines of segment Z by urging major collapsing fold C to fold inward which permits creases s, t and u to enable crease t to fold and extend out, thus permitting the complete collapse of the device. Total collapse of device 10 is clearly depicted in
It is also apparent from
Preferred embodiments of the disclosed device 10 are currently fabricated from a variety of plastic materials. The device is manufactured by injection molding. The flexible wall member 18 and top member 14 are molded from elastomeric silicones specifically blended to provide the ideal flexibility, integrity and durability. Clearly the wall member, when fully or partially extended, needs to demonstrate sufficient structural integrity to support a partially filled container of meaningful size and be flexible enough to fold and collapse into smaller sizes, as appropriate for use, and/or ultimately collapse completely for storage. Also, the elastomeric nature of the top member and its orifice enables the device to adapt to a wide range of container designs so that a variety of container shoulders and necks can be accommodated. The base member 12 is currently not perceived as needing the flexibility of the top and wall members, so it is preferably molded from a plastic such as PVC, polypropylene or polyethylene. And, clearly, all elements of the device need to demonstrate sufficient durability to withstand repeated cleanings and use.
While the foregoing is a detailed and complete description of the preferred embodiments of the disclosed device and its use for supporting and suspending inverted containers to facilitate the removal of contents from the container, it should be apparent that numerous variations and modifications can be made and employed to implement the overall purpose of the disclosed device without deviating or departing from the spirit of the invention, which is fairly defined by the appended claims.
