Abstract: A container includes a lid base and a compressible portion. The lid base has a channel and configured to receive a lid. The compressible portion is connected to the lid base. The compressible portion includes a one-way valve in air communication with the channel. Another container includes a compressible portion and a container base. The compressible portion includes a bellow body, which includes at least two convolutions, each including a first living hinge and a first sidewall, at least one second living hinge positioned between the at least two convolutions and connected to the first sidewalls, and a movable bump structure positioned between the at least two convolutions to space the first living hinges apart and being movable between an outer position and an inner position relative to a container interior.

Abstract: A storage container includes an elastomeric base having a plurality of side walls forming an interior and an opening at an upper edge of the base. The base has an annular channel positioned proximate the opening at the upper edge of the base. An inner insert is removably positionable in the opening of the base, the inner insert having an outward facing annular protrusion configured for insertion in the annular channel of the base, and a spout with a channel formed therethrough. At least a portion of the spout has external threading. An outer cap is positionable over the inner insert and has an opening for receiving the spout. A screw cap includes internal threading configured for rotational engagement with the external threading of the spout, wherein rotation of screw cap compresses at least a portion of the base between the inner insert and the outer cap.

Abstract: A container, includes a collapsible portion and a container base. The collapsible portion has a first step structure; a second step structure; and a hinge assembly coupled between the first step structure and the second step structure. The container base is coupled to the collapsible portion. Another container includes a container base; a collapsible portion, coupled to the container base; a lid base, coupled to the collapsible portion; a ring, coupled to the lid base and sandwiching a periphery of the collapsible portion with the lid base; and a lid assembly, coupled to the ring when the container is in a closed status.
