초록

Collapsible household containers having a foldable wall section with shape-retaining characteristics are disclosed. In particular, collapsible laundry baskets, buckets, colanders, dish drainers, cups, and bottles are provided. The folding region 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 rigid material.

1. A collapsible bottle comprising a generally annular, rigid top tier;a bottom tier including an imperforate bottom surface; anda collapsible wall section connecting the top tier to the bottom tier, the collapsible wall section including at least three stacked, generally annular tiers;the collapsible wall section, top tier, and bottom tier collectively defining a watertight container body having a fluid outlet and a container volume disposed in an interior of the container body below the fluid outlet;at least one of collapsible wall section tiers being a rigid middle tier; andat least two of the collapsible wall section tiers being flexible and configured to fold between relatively expanded and relatively collapsed positions, including at least one flexible tier disposed above the middle tier and at least one flexible tier disposed below the middle tier, the flexible tiers being composed of a flexible material and the middle tier being composed of a rigid material different from the flexible material, the middle tier comprising an exposed exterior surface of the rigid material facing away from the container volume;wherein the size of the container volume can be increased by folding at least one of the flexible tiers from a relatively collapsed to a relatively expanded position and can be decreased by folding at least one of the flexible tiers from a relatively expanded to a relatively collapsed position, each successively lower tier of the bottle having an interior perimeter larger than an exterior perimeter of each higher tier, the top tier being at least partially inserted into the middle tier when collapsed, and the middle tier being at least partially inserted into the bottom tier when collapsed. 2. The bottle of claim 1, the fluid outlet being disposed in the top tier, the fluid outlet configured to be opened and closed to selectively allow and restrict the flow of fluid out of the container body through the fluid outlet. 3. The bottle of claim 2, further comprising a cap removably covering the fluid outlet. 4. The bottle of claim 2, further comprising a valve connected to the top tier to open and close the fluid outlet. 5. The bottle of claim 2, further comprising a cap retention member permanently connected to the cap and to the container body to permit the cap to be removed from the fluid outlet while remaining connected to the container body. 6. A method of making a collapsible bottle, comprising forming a rigid, generally annular top tier;forming a rigid bottom tier including an imperforate bottom surface and having an interior perimeter larger than an exterior perimeter of the top tier;forming a collapsible wall section connected to the top tier and the bottom tier, forming the collapsible wall section comprising forming at least a first rigid middle tier having an exterior perimeter smaller than the interior perimeter of the bottom tier and an interior perimeter larger than the exterior perimeter of the top tier, a first flexible tier disposed between the middle tier and the top tier, and a second flexible tier disposed between the middle tier and the bottom tier, the flexible tiers being composed of a flexible material and the top, bottom, and middle tiers being composed of a rigid material different from the flexible material, the middle tier comprising an exposed exterior surface of the rigid material facing away from the container volume, each flexible tier being adapted to fold between at least one relatively expanded position and at least one relatively collapsed position;joining the first flexible tier to the middle tier and the top tier, to provide watertight connections between the first flexible tier and the respective middle and top tiers, and the second flexible tier to the middle tier and the bottom tier, to provide watertight connections between the second flexible tier and the respective middle and bottom tiers, so that the collapsible wall section, top tier, and bottom tier collectively define a watertight container body; andproviding a fluid outlet comprised in the container body, for pouring fluid from the container body through the fluid outlet. 7. The method of claim 6, wherein said providing a fluid outlet comprises forming the top tier to define a fluid outlet. 8. The method of claim 7, further comprising forming a cap to configured to removably cover the fluid outlet. 9. The method of claim 7, further comprising forming a valve connected to the top tier to open and close the fluid outlet. 10. The method of claim 8, further comprising forming a cap retention member and permanently connecting the cap retention member to the cap and the container body to permit the cap to be removed from the fluid outlet while remaining connected to the container body.
