Ergonomic Receptacle Having Viscoelastic Skin

FIELD OF THE INVENTION

This invention is drawn to the field of receptacles; more particularly, to receptacles of compound wall construction, and still more particularly, to novel ergonomic receptacles having viscoelastic skins.

BACKGROUND OF THE INVENTION

The prior art is replete with a variety of compound wall cups, cupholders, beverage holders, food dispensing containers and other vessels of diverse construction and purpose. Some employ an insulative outer skin, and/or an internal coolant or heating chamber, to insulate the hand, and/or to chill or to warm a beverage or other aliment. Reference in this connection may be made to United States patent documents D509996, 20050226965, 20070051736, U.S. Pat. Nos. 4,163,374, 4,183,226, 4,299,100, 4,324,111, 4,768,354, 5,361,604, and 7,458,504, each incorporated herein by reference. U.S. Pat. Nos. 5,753,289, 6,641,854, and 7,063,229, each incorporated herein by reference, are exemplary of another type of compound wall cup or other vessel used for dispensing together a liquid such as milk with a solid, such as cereal, or another two types of aliment. Other heretofore known compound wall cups or other receptacles include those that have a transparent outer layer and a patterned inner wall visible through the transparent outer layer, as is exemplified by U.S. Pat. No. 5,894,948, incorporated herein by reference.

The hand typically conformed to the shape and profile of the cup, container or other vessel of compound wall construction with more or less comfort, in dependence on the shape and profile of the cup or other receptacle. For any given profile and construction, because of the differing hand sizes among adults, and between adults and children, the heretofore known receptacles of compound wall construction were maximally comfortable and useful primarily to those of average or other target size hands but their comfort and utility was limited for those having other than average or targeted hand sizes, often resulting in discomfort and sometimes in lack of use. Moreover, the sureness of grip depended on the size and shape of the hand and the shape and profile of the cup, cupholder or container receiving the hand. The greater the mismatch therebetween the more the heretofore known cups, containers or other receptacles of compound wall construction were subject to damage or spillage from undesired droppage or slippage.

SUMMARY OF THE INVENTION

It accordingly is the principal object of the present invention to disclose an ergonomic receptacle having a viscoelastic skin not subject to the disadvantages of the heretofore known receptacles of compound wall construction.

A related object of the present invention is to disclose such an ergonomic receptacle having a viscoelastic skin that locally deforms when grasped in such a way as to comfortably conform to a wide variety of hand sizes and shapes of both adults and children.

A related object of the present invention is to disclose such an ergonomic receptacle having a viscoelastic skin that forms a contour grip that is comfortable and that does not easily slip out of hand.

In accord with these and other objects, the ergonomic receptacle having a viscoelastic skin of the present invention includes a vessel having walls defining a receiving void. The vessel may, for example, be a cup and the receiving void, may, for example, serve to contain a drink.

A viscoelastic skin is provided about the vessel to cover at least a major portion of its peripheral surface. The viscoelastic skin exhibits no flow when in steady-state, is soft to the touch and viscoelastically flows to take a negative imprint of a hand gripping the receptacle displacing the viscoelastic skin between the hand and confronting surface of the vessel to allow the hand to comfortably and securely grasp the confronting wall of the vessel, and returns towards its condition of undeformed equilibrium when released. The viscoelastic skin provided about at least a major portion of the peripheral surface of the vessel may in alternate disclosed embodiments be monolithic or may be composite. In alternate disclosed embodiments, the viscoelastic skin may be a bag that captures the peripheral sidewalls and included bottom wall of the vessel and may be sleevelike so as to surround at least the major portion of the peripheral surface of the vessel.

Flat, dimpled and apertured bottom caps are disclosed in alternate exemplary ergonomic receptacles having sleevelike viscoelastic skin embodiments.

The viscoelastic skin and vessel are permanently attached in alternate presently preferred and exemplary embodiments by adhesive and laser bonding, by molding and by means of mechanical capture although other attachment or joining techniques could be employed without departing from the inventive concepts.

The viscoelastic skin may be translucent or transparent and the walls defining the peripheral surface of the vessel may be patterned with structural or decorative features and/or imprinted with company logo's or other indicia or information.

In any of the monolithic viscoelastic skin embodiments of the ergonomic receptacle having a viscoelastic skin in accord with the present invention, the monolithic viscoelastic skin may be a thermoplastic elastomer, silicone, polyurethane, rubber or other similar material. In any of the composite viscoelastic skin embodiments thereof, the skin material may be of cellophane or thermoplastic elastomer, silicone, polyurethane, rubber or other flexible material; the viscoelastic material may be a gel or gel-like material of glycol or silicone or other composition or a mixture of materials and may be solid or semi-solid regular or granular or other material with such properties to assimilate flow-like movement. The vessels may be made of polypropylene or other material, such as other plastics or metals, including, but not limited to, polyethylene, polycarbonate, nylon, or stainless steel, and the joining, retaining and sealing rings may be made of polypropylene or other material, other plastics or metals, including, but not limited to, polyethylene, polycarbonate, nylon, or stainless steel.

Although a viscoelastic skin is presently preferred, another monolithic or composite flexible skin that exhibits no flow when in steady-state, is soft to the touch and conforms to take a negative imprint of a hand gripping the receptacle displacing the skin between the hand and confronting surface of the vessel to allow the hand to comfortably and securely grasp the confronting wall of the vessel, and returns towards its condition of undeformed equilibrium when released may be employed in accord with the present invention.

It should be noted that the different disclosed attachments of the skins and vessels are exemplary and that different attachments and/or different arrangements of the various disclosed attachments at the top and/or bottom interfaces of the baglike and/or sleevelike skins and vessels are contemplated including molded attachments, attachments bonded adhesively, by laser weld or otherwise and mechanically attached.

Many modifications of the presently disclosed invention will become apparent to those of skill in the art having benefitted from the instant disclosure.
