Collapsible
spiral container
Abstract
A collapsible container has a sidewall comprised of a plurality of adjacent
raised spirals defining grooves therebetween. Each spiral is comprised of a top
side of a first vertical cross section plane length (width) and a shorter
bottom side meeting at a fold line. When sufficient force is applied, the
bottom side folds inwardly under the upper side, thus collapsing the sidewall
and the container.

Collapsible
faceted container
Abstract
A multi-faceted collapsible container has a sidewall of joined-together rings
comprised of pyramidal segments having peaks extending outwardly. Each segment
is comprised of four polygonal facets; the upper pair of facets is longer than
the lower pair. Sufficient vertical force causes the smaller lower facets to
fold under the longer upper facets, collapsing the rings and the sidewall of
the container.

Collapsible-stackable
plastic container
Abstract
A stackable collapsible container has a sidewall comprised of opposing conical
sections. The upper conical section has a greater length and slighter angle
than the lower conical section. Upon application of vertical force the lower
section folds under the upper section, so the container assumes a stable
collapsed state; and likewise, the necked conical top collapses to further
reduce the overall length. The top of a collapsed container has a groove, so
that when the top is mated to a ringed recess in a like second container, the
containers resiliently lock to each other and thus may be readily stacked.
