Collapsible multi-purpose containers
Collapsible indoor and outdoor containers having a collapsible wall section with shape-retaining characteristics are disclosed. In particular, collapsible coolers, fish bins, and wheeled vertical bins are provided. The collapsible wall section may include foldable tiers of a flexible material, each tier having at least one stable, relatively expanded position and at least one stable, relatively collapsed position; and an intervening, non-folding tier composed of a different, relatively stiff or rigid material. The coolers, fish bins, and wheeled vertical bins are each advantageously provided with a collapsible insert container that nests within and collapses together with a shell of the respective container, the respective wall folds of the shell and insert meshing together to result in a combined collapsed vertical dimension as small or nearly as small as that of the collapsed shell alone.
1. A collapsible mobile container comprising
a collapsible shell having a top opening, a closed bottom, and a closed periphery defining a shell volume disposed below the top opening, the collapsible shell comprising
a generally annular top shell tier;
a bottom shell tier including a generally horizontal support surface; and
a collapsible wall section connecting the top shell tier to the bottom shell tier, the collapsible wall section including at least three stacked, generally annular tiers;
at least one of the collapsible shell wall section tiers being a stiff middle shell wall section tier; and
at least two of the collapsible shell wall section tiers being flexible and configured to fold between relatively expanded and relatively collapsed positions, including at least one flexible shell wall section tier disposed above the middle shell wall section tier and at least one flexible shell wall section tier disposed below the middle shell wall section tier;
wherein the size of the shell volume can be increased by folding at least one of the flexible shell wall section tiers from a relatively collapsed to a relatively expanded position and can be decreased by folding at least one of the flexible shell wall section tiers from a relatively expanded to a relatively collapsed position;
at least two wheels connected to the shell bottom tier for rolling movement of the container along a generally horizontal supporting surface;
an elongate bracing member movably connected to the top shell tier for movement between a generally horizontal stowed position and a bracing position extending generally vertically alongside the periphery of the collapsible shell in a relatively expanded position, the bracing member configured to brace in compression between the shell top tier and the shell bottom tier to inhibit collapsing movement of the shell top tier towards the shell bottom tier; and
a handle pivotally connected to the shell top tier proximate to the location of the connection of the bracing member to the shell top tier, the handle being lockable so that the container can be tipped onto the wheels for rolling the container on the wheels wherein said handle and said end of the bracing member being pivotally connected to the shell top tier about a common horizontal axis.
2. The container of claim 1 , wherein the bracing member in the bracing position has a connector removably mated to a corresponding connector in fixed relation to the shell bottom tier.
3. The container of claim 1 further comprising a lid for closing the container, the lid having a depression, wherein the handle and the bracing member can be being pivoted around the common axis into the depression.
