Benefits of technology

[0004] A principal object of the present invention is to provide a collapsible container which presents or forms a substantially rigid receptacle in its open or expanded position and which, with an appropriate lid or seal snap-fit thereto, provides a practical watertight storage container for, as an example, an appropriate foodstuff or the like. The container is very convenient and provides a particularly desirable portable solution for food “on-the-go”, such as at picnics, lu

Embodiment Construction

[0025] In the drawings, the features of the embodiment of FIGS. 1-11 are referred to by two digit numbers. Similar features in the embodiment of FIGS. 12-22 are referred to by the same numbers with the number 1 as a prefix.

[0026] Referring now more specifically to the drawings, the collapsible container 10 comprises a base 12, a top ring 14 and a folding wall 16 extending therebetween. The base 12 is a substantially rigid member including a bottom 18 with a peripheral upstanding base wall 20. The base, which may be flat, preferably includes a central slightly upwardly extending pressure area or bump 24 of any appropriate configuration, such as a dome, to assist in expanding the container as shall be described subsequently. The base will also preferably have a series of small foot defining knobs 26 or a continuous foot rib, not shown, depending from the base bottom 18.

[0027] The top ring 14 includes a continuous or annular ring wall 28 with a peripheral horizontally outwardly direc...

Abstract

A collapsible container with angularly related multiple folding sections, each section extending at an angle to the vertical, and flexure zones between adjacent sections for flexibly moving the sections between a first open position in the expanded container and a second position folded upon itself in the collapsed container, the flexure zones resisting movement of the sections in both the fully expanded container and the collapsed container, as well as any intermediate position wherein only selected flexure zones are in an open position.

Description

[0001] This is a continuation-in-part of application Ser. No. 10 / 735,724, David Kusuma, filed Dec. 16, 2003.BACKGROUND OF THE INVENTION [0002] The present invention generally relates to molded plastic containers of the type commonly used for a variety of purposes including storage of both food items and non-food items, such containers preferably being adapted to receive an appropriate seal or lid. More specifically, the invention is concerned with containers of this type which, rather than being of a rigid construction as with a conventional bowl, are collapsible or foldable to a compact position when empty to facilitate convenient storage. [0003] Such containers, in the form of cups, bowls, and the like, are generally known in the art and take many forms. These include collapsible cups or glasses wherein the glass is formed of telescopically stacked annular wall elements which slide relative to each other between a fully extended position and a collapsed position. As the wall eleme...
