Abstract
A semi-rigid container, has a semi-rigid folding portion consisting of the plurality of diamond shaped panels forming a frustoconical shape. The panels are arced relative to the interconnecting frustoconical substrate in the transverse and longitudinal directions so that while the panels provide rigidity against a longitudinal collapsing force, they are able to expand transversely to enable folding of the folding portion under the longitudinal collapsing force and to resist expansion from the collapsed state. Other shapes of the panels are also described.
