Definitions

  • My present invention relates to a collapsible drinking and/or storage receptacle and, more particularly, to a drinking cup or like vessel which can be collapsed to a substantially flat configuration.
  • Collapsible drinking cups utilizing telescoping structures and conical cups with circular segments which seal relative to one another as the cup is extended are known in the art.
  • Other collapsible receptacle configurations are known as well.
  • the bottle is made from plastic.
  • collapsible containers which is stable, reliably sealable, compact in its collapsed or contracted position and capable of extension or expansion into a conveniently usable receptacle for beverages and the like as well as for storage and other receptacles capable of being collapsed and effectively stored in the flattened state.
  • the principal object of the present invention to provide a collapsible receptacle which is free from the drawbacks of earlier receptacles and containers, which can be manufactured at low cost, can be collapsed to an especially thin and flat structure, is of light weight and has an aesthetically pleasing appearance.
  • Another object is to provide an improved collapsible drinking cup which can be utilized repeatedly and over long periods of time without a tendency to leak, is convenient to use and can be collapsed and erected in a simple way.
  • a collapsible container which has a wide mouth and a small bottom and a plastic continuous membrane wall connecting the bottom with a rim of the mouth and which is collapsible so that, in the collapsed position, the mouth rim is coplanar or substantially in the same plane as the bottom.
  • a resilient cup-shaped body of a silicone rubber or other shape-memory synthetic resin is provided between the rim and the bottom and can fold between the cover and the bottom disks so that it automatically can spring from its compacted position into its extended position while the membrane of the wall maintains a perfect seal between the ring defining the mouth and the bottom.
  • the cup-shaped body is formed with a helical corrugation to enable the membrane wall to collapse between the cover and bottom disk in an ordered manner.
  • the bottom of the cup is formed by or is bonded to a disk-shaped member which is engaged with another annular disk shaped member formed by or at the rim of the mouth, the two disk shaped members being interconnectable by a releasable catch which can retain the cup in its compact or contracted position.
  • a removable lid may span across the mouth of the cap to seal the latter in its closed position when, for example, the cup contains a beverage and the user wants to transport that beverage from one location to another.
  • the lid itself can be connected to the upper disk by a hinge or catch system as may be convenient. All of the parts of the cup may be composed of a synthetic resin material and can be injection molded or extruded so that the overall cost of the collapsible cup is at a minimum.
  • the lid and bottom of the cap may be formed with a logo, design or legible matter by embossing or in the molding process or by a printing process, representing a distributor of the cup as a promotional item or otherwise.
  • the resilient membrane body may have a generally circular cross section
  • the membrane body may have a rectangular cross section or a spiral, an oval, or other cross section as may be desired.
  • the lid or cover of the container should be capable of sealing to the top rim of the body.
  • the lid can be removed or a straw-receiving hole in the lid can be provided to allow a beverage to be sipped through the hole.
  • the collapsible cup whose principal elements are shown in FIGS. 1-3, comprises an upwardly round injection-molded disk-shaped bottom or base member 10, an elastic, collapsible, downwardly tapering cup-shaped member 11 of a food-compatible material such as a silicone rubber or other elastomeric, a mouth ring 12 of injection-molded synthetic resin and a disk-shaped cover 13 which is likewise injection-molded.
  • a food-compatible material such as a silicone rubber or other elastomeric
  • a mouth ring 12 of injection-molded synthetic resin and a disk-shaped cover 13 which is likewise injection-molded.
  • FIG. 1 The expanded position of the cup is shown in FIG. 1 and its collapsed position has been illustrated in 19.
  • the internal cup-shaped member 11 has a relatively thick base 15 with lugs 16 spaced therearound and shaped to enable those lugs to be press-fitted into corresponding grooves 17 of an equal number of ribs 18 molded unitarily with the bottom 10 (see FIGS. 15-18), the ribs 15 being spaced apart by gaps 19 equal in circumferential length or arc length to the rib.
  • the base 15 and the bottom 10 can be relatively rotated to bring the lugs 16 snugly into the grooves 17 and thereby lock the bottom 10 onto the internal cap 11.
  • the internal cup 11 is unitarily injection-molded with an upstanding thin wall 20 of frustoconical configuration which diverges upwardly to a mouth 21 or converges downwardly to the base 15, but is formed with a slight helical corrugation 22 which functions as a formation in this wall facilitating its ordered collapse as the mouth 21 is pressed toward the base 15.
  • the wall 20, however, is sufficiently resilient so as to have an intrinsic spring action and in effect be an internal spring which jumps upwardly to the erect position shown in FIGS. 1 and 14 when the cover is released from the bottom.
  • the rim 23, molded unitarily with the wall 20, is press-fitted, on assembly over an annular shoulder 25 of the ring 12 and into an outwardly open groove 26 in this ring.
  • the ring 12 is referred to as a mouth ring, is injection-molded with an apron 27 tapering in thickness downwardly around the outer portion of the cup 22 and serves to maintain the stability of the mouth during the collapse of that cup and for sealing with the cover.
  • the bottom 10, the mouth ring 12 and the cover 13 are all injection-molded from the same relatively rigid, food-approved and food-compatible material.
  • the mouth ring is dimensioned to fit snugly around a downwardly-extending rib 30 on the underside of the cover surface 31 of the member 13 whose outer wall 32 diverges downwardly, can be provided with external formations 33 to facilitate gripping and has three angularly equispaced internal formations or bumps 34 which, as will be described in greater detail hereinafter, form part of a bayonet fastener with the bottom member.
  • the space 35 between the rib 30 and the wall 32 thus accommodate the mouth of the internal cup formed by the ring 12 and the rim 23.
  • the cover wall 30, whose external surface may be embossed or imprinted with promotional material, a corporate logo, or other legible, decorative or aesthetic material or information, can have a hole 36 which may be covered by a shutter 37 which can have an opening 38 pressed over a pin 39 (compare FIGS. 2 and 8).
  • the shutter 37 within the cover 13 closes the bore 36 but can be deflected by a straw upon its insertion through the hole 36.
  • the base 10 is provided with three angularly-spaced bayonet formations at 40 to receive the bumps 34.
  • These bayonet formations comprise downwardly-extending recesses 41 opening into circumferential recesses 42, below a ridge 43 formed by the downwardly and outwardly diverging flanks 44 of the side wall 45 of the bottom 10. Since the flank 44 diverges outwardly when the cover is pressed over the bottom 10, the bumps 34 slide along the flank 44 until they jump into the grooves 42 of respective bayonet formations. The result is a collapsed position seen in FIG. 19. To open the cup, the bottom 10 and the cover 13 are rotated relatively until the bumps pass into the grooves 41.
  • the bottom wall 50 of the cup can be formed with a pair of recesses 51, 52 with steep flanks 53 and 54 enabling gripping by the fingers of the user to facilitate relative rotation of the bottom and the cover.
  • the rim 23 forms a gasket which can be sealed by the cover 123 when the cover is replaced on the cup in its extended position for storage of the contents.
  • the cup In the compact position the cup can have a total height about an inch or less as compared with a height of almost four inches when expanded and an overall diameter of slightly more than four inches.
  • FIG. 20 I have shown the same principle applied to a food container 60 in which the wall 61 has a helical corrugation 62 molded therein between an upper rim 63 and a base member 64 which is received in the apron 65 of the rim and in which similar catches 66, 67 can be provided as were used in the embodiments of FIGS. 1 - 9 to hold the container in the closed position. Only a very slight relative twist is required to engage or disengage the catches.
  • Other shapes are of course also possible for the food container and a variety of lids can be provided, either permanently secured to member 63 or adapted to fit over the rim 63 as, for example, with certain lids for containers marketed under the trademark "TUPPERWARE".
  • the bottom member 10 or 65, the wall 11 or 61, the rim member 23 or 63 and any lid can be embossed or otherwise provided with promotional indicia.
  • the rim member 23 or the bottom member 10 although generally flat, is designed to fit within the other member in the collapsed state of the receptacle.
