A collapsible receptacle, such as a beverage cup, that is reconfigurable between expanded and collapsed configurations with an inner sleeve with first and second opposed major walls divided by opposed fold lines, an outer sleeve with first and second opposed major walls divided by opposed fold lines, and a liner retained by the inner and outer sleeves. The receptacle is retained in an expanded configuration when the opposed fold lines of the inner and outer sleeves are not aligned, and the receptacle can be collapsed when the opposed fold lines are aligned. A lid can be removably retained by a retaining ring. The opposed fold lines of the inner and outer sleeves can be disposed in groups, such as groups of two fold lines, so that the sleeves have opposed minor walls. The major walls can taper in thickness from their mid-portions to the opposed fold lines.

Embodiments of the present invention provide a cover of a collapsible cup. According to one embodiment, a device comprises a cover for a cup, the cover comprising a lid having a periphery, a peripheral wall extending from the periphery of the lid generally oblique or perpendicular to the general orientation of the lid, and a compartment attached to or formed within the lid, the compartment forming a unitary structure of the lid and the compartment, wherein the compartment extends beyond the periphery to create an overhang portion of the compartment beyond the lid.

A container 401 comprising: a base 402; and a sidewall 404 extending from the base 402; wherein the base 402 and the sidewall 404 define a cavity for containing a consumable; the sidewall 404 comprising at least in part a sidewall element 406 deformable between a compressed state in which the cavity has a first volume and an uncompressed state in which the cavity has a second volume; the sidewall element 406 configured to be bistable such that the sidewall element 406 will remain at rest in equilibrium in both the compressed state and the uncompressed state; wherein the sidewall element 406 is movable between the compressed and uncompressed states by input of an activation energy to the container 401.

A foodware storage system includes a storage rack, a hook assembly, and a foodware item. The storage rack includes a rod having an adjustable length coupled between a first support and a second support to maintain the rod in an elevated position above a surface upon which the storage rack is placed. The rod is disconnectably connected to at least one of the supports. The hook assembly includes a hanger and a hook. The hook is suspended from the hanger and the hanger is configured to slidably move along the adjustable length of the rod. The foodware item has an aperture dimensioned to receive the hook such that the foodware item can be hung from the hook to dry when wet.

The present invention relates to a foldable cup, includes a front side having at least one supporting axis, broken in a circumference direction of a cup, for vertically sustaining load; a back side having at least one supporting axis, connected with both side ends thereof to be faced with the front side and broken in the circumference direction of the cup, for vertically sustaining the load; and a foldable bottom surface having 6 variable structures connecting each of ends to lower ends of the front side and back side, wherein the bottom surface includes a foldable line for two dividing it to be folded between the front side and back side; a main axis, crossing the foldable line diagonally, bent toward the inside and outside, and for sustaining the load of the bottom; and a plurality of sustaining lines, disposed at both ends of the bottom surface, respectively, connected between two apexes meeting with the foldable line and another apexes adjacent to them wherein the main axis is connected to at least one of the sustaining lines of each apex meeting with the foldable line to disperse the load, thereby to maintain the original form of the cup more longer by easily dispersing load of the contents.

A portable collapsible container for transporting fluids. The container is formed of flexible walls that can be folded to collapse the container. A specialized rim is connected to the container walls through a transition collar which enables a hard rim to be joined to relatively soft and pliable walls. A metallic ring is embedded in an upper aspect of the container to maintain the container in cylindrical form and prevent denting of the rim which could cause separation of the lid from the rim.
