A variable volume evacuable container has a closed bottom, an open top, and a spirally threaded inner wall extending therebetween. A lid configured to threadably engage the inner wall has a top surface, a perimeter, a bottom surface, and a funneling volume within the perimeter and below the bottom surface. A duct is defined through the top and bottom surfaces at the apex of the funneling volume, and a moveable baffle is coupled to the top surface to cover or uncover the duct. The bottom surface slopes continuously upward to the apex so that downward rotation of the lid against contained liquid forces air out of the duct until the liquid fills the funneling volume, allowing the baffle to seal the liquid from air by covering the duct.

Collapsible reusable watertight carrying cases are provided in sizes varying from small containers without wheels to large sealable container bins on wheels, to provide large quantities of water or other supplies and cargo. The cases are assembled or disassembled from a joined flat space-saving configuration to a functioning case and vice-versa. The sides of the cases are erected progressively by hand by interlocking self sealing reciprocating channel and channel engaging members elements at the corners. The panels also disassemble progressively by being manually pulled apart. Optional foldable locking latches provide stability and aesthetics to the carrying case. When folded into a flat storage or shipping configuration, the panels stay together, resisting unfolding by virtue of snaps which are either molded into the panels or bonded to them. The carrying cases are resistant to water, dirt, bacteria, molds, allergens, and inclement weather.

An easily detachable airtight container includes a container body, a first upper cover, a second upper cover and a handle. The second upper cover is disposed between the container body and the first upper cover. The first upper cover has an opening, while the second upper cover has a convex block which passes through the opening. The handle includes a body. The body has a first coupling portion, while the convex block has a second coupling portion. The first coupling portion and the second coupling portion may are detachably connected. When the first coupling portion is coupled with the second coupling portion, the first upper cover is sandwiched between the second upper cover and the handle. In the present disclosure, the handle forms a detachable connection with the convex block by means of the coupling portions.

Collapsible reusable watertight carrying cases are provided in sizes varying from small containers to large sealable container bins on wheels, to provide large quantities of water to remote areas not served by public water supplies, or where water supplies are unavailable because of weather disasters. The cases are assembled or disassembled from a joined flat space-saving configuration to a functioning case and vice-versa. The sides of the cases are erected progressively by hand by interlocking elements at the corners. The panels also disassemble progressively by being manually pulled apart. When folded into a flat storage or shipping configuration, the panels stay together, resisting unfolding by virtue of snaps which are either molded into the panels or bonded to them. The carrying cases are resistant to water, dirt, bacteria, molds, allergens, and inclement weather.

A locking cooler assembly includes a cooler that can store perishable items. The cooler is comprised of a thermally insulating material to retain the perishable items at a preferred temperature. A divider is hingedly coupled to the cooler and the divider opens and closes the cooler. A lid is hingedly coupled to the divider and the lid and the divider define a storage space when the lid is closed for storing non-perishable items. A locking unit is coupled to the divider and the locking unit engages the lid when the locking unit is engaged to secure the objects stored in the storage space defined by the divider and the lid. A remote control is in remote communication with the locking unit to facilitate the user to remotely disengage the locking unit.

A storage container is disclosed, which includes: a container body; a folding line enabling folding and unfolding; a cover comprising a first and a second cover provided on the left and right sides of the folding line; a rotary pressing member rotatably provided on or near the folding line; and an elastic element coupled to the outer edge or inner side of the cover, wherein the cover can be inserted into the container body while folded, the cover is unfolded by a rotation of the rotary pressing member in one direction, the rotary pressing member is coupled to the cover so that the elastic element comes tightly contacts the inner wall surface of the container body and the cover maintains an unfolded state, and the cover is folded by a rotation of the rotary pressing member in the other direction so as to be separable from the container body.

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.

A case for a flag that opens to form a base for the flag. The case is for an indoor/outdoor lighted stand in a box-like configuration that when opened provides a surface to securely hold poles that are two inches in diameter or smaller and twelve feet or less in overall height.

An alignment positioning structure for a container lid handle and a holding part includes: a body formed by surrounding a side to form an accommodating space, and a longitudinal lengthwise columnar body with an open end communicating with the accommodating space; a gripping protuberance being a convex surface protruded from a side of the body and each opposite end of the convex surface having an inwardly bent force applying surface; a lid having a combining section extended from a side of the lid for combining with the open end of the body and having two opposite first combining portions; a handle having two opposite end portions with a second combining portion for combining the two first combining portions; and a compensation portion having a gap formed between the lid and the open end of the body to define a relative position between the handle and the gripping protuberance.
