Abstract
Abstract A collapsible, disposable food container includes a main body which is selectively adjustable between an operative, open position and a collapsed, flat position thereof. The container is constructed from a unitary piece of flat stock material folded to define front, back, side, and bottom walls. The container includes a main body having a bottom portion which is shaped substantially as a truncated cone, when the container is in its operative position, such that the bottom portion may be inserted in and stably engage the walls of a circular opening, such as a vehicle cup holder. Most preferably, the lower portion of the main body fits within a circular area 2.75 inches in diameter. In a preferred embodiment of the invention, each side wall includes an indentable gripping brace region, intermediate of upper and lower portions of the side wall, which can be flexed inwardly of the upper and lower portions of the side wall, when inwardly directed pressure is applied thereto. It is preferable that the indentable gripping brace regions be substantially football shaped. In an optional embodiment of the invention, the container further includes a secondary, body integrally formed with the main body, for holding auxiliary foodstuffs such as condiments. Where used, the secondary body defines a pocket connected to one of the front, back or side walls of the main body.

Claim 4
Dependent Claim
44 words
A collapsible food container as recited in claim 1 , wherein each of said side walls includes a support leg which extends below said bottom wall when said main body is in its open position, for stably supporting said container on a flat surface.
Claim 5
Dependent Claim

A collapsible food container as recited in claim 3 , wherein said container further includes overlapping panels extending from said side walls, respectively, and connected to portions of at least one of said front and back walls in an overlapping manner; said overlapping panels also having support legs extending below said bottom wall to provide additional support for said container on a flat surface.
Claim 6
Dependent Claim
52 words
A collapsible food container as recited in claim 1 , wherein said bottom wall includes: a front section; and a rear section separated from said front section by a score line along which said bottom wall is collapsible; said front and rear sections of the bottom wall being non-symmetric to each other.
Claim 7
Dependent Claim
49 words
A collapsible food container as recited in claim 5 , wherein the distance between said back wall and said score line along said bottom wall is greater than the distance between said front wall and said score line along said bottom wall for further increasing stability of the container.
Claim 8
Dependent Claim
101 words
A collapsible, disposable food container, comprising: a main body; said main body being selectively adjustable between an operative, open position and a collapsed, flat position; said main body being constructed of a unitary piece of flat stock material folded to define a front wall, a back wall, a pair of opposed side walls, and a bottom wall; wherein each side wall includes an indentable gripping brace region, intermediate of upper and lower portions of the side wall; said indentable gripping brace region flexing inwardly of the upper and lower portions of the side wall when inwardly directed pressure is applied thereto.
