SNAP-FOLD CONTAINERS

摘要

The invention disclosed includes various durable containers constructed from sheet materials including a plurality of living hinges. The containers are configured to snap into an assembled position from a relatively flat position by the application of pressure to one or more sidewalls wherein that pressure deforms the one or more sidewalls into a concave position, thereby holding the container into place until the contain is collapsed once again for storage or cleaning.

主权项

1. A collapsible container constructed from a single sheet of material comprising:
first, second, third, and fourth sidewalls defined on the sheet of material, wherein the first sidewall is provided opposite the third sidewall and the second sidewall is provided opposite the fourth sidewall; a substantially planar bottom surface defined on the sheet of material; an interior compartment surrounded on four sides by said first, second, third, and fourth sidewalls and on the bottom by said substantially planar bottom surface; an upper rim projecting inwardly from each of the sidewalls; and at least three living hinges integrally formed in each of said first, second, third, and fourth sidewalls, wherein said living hinges are positioned in a manner permitting the container to be easily snapped into an assembled position, and further wherein a first top living hinge at the juncture of the upper rim and the first sidewall follows a curved path, and a second top living hinge at the juncture of the upper rim and the third sidewall follows a curved path.
