Collapsible container
摘要:
A collapsible container formed from a cut and scored blank of paperboard or similar foldable sheet material which, when set up, provides a tubular body having an open top with a circular cross section and a bottom wall structure which comprises panels integrally hinged along straight lines to the bottom edge of the tubular body, which panels are connected in pairs and are automatically foldable inwardly between the body side wall forming panels when the latter are collapsed and which, when the container is opened up, have interlocking portions adapted to hold the bottom wall panels in an upwardly directed cone-shaped formation, thereby providing a support for the container contents which has a degree of resiliency.
