Disclosed are a container cover and a vacuum preservation container. The container cover comprises a cover body and an air extraction assembly, wherein a first through hole is provided in the cover body, the air extraction assembly comprises an outer cover and an inner cover, the inner cover is arranged on an upper end of the first through hole in a sealing manner, a second through hole and a third through hole are provided in the inner cover, the second through hole is in communication with the first through hole, a first one-way valve is arranged in the second through hole, and a second one-way valve is arranged in the third through hole.

The invention relates to a fluid delivery assembly (1) for a spray gun, the assembly comprising a container (20) for holding paint. The container is self-supporting and configured to collapse as fluid is dispensed via the spray gun, wherein the container comprises at least one vent (26). The invention further relates to a spray gun including such fluid delivery assembly, a method of forming the container and a thermo/vacuum forming tool to be used in such method.

A drinking vessel has a cup with a removable lid having at least one inlet-outlet opening which receives an elastic straw-vent assembly having a flexible tubular straw or spout and a ventilation member that defines an air passageway and a vent opening. A vent actuator is operably coupled to the ventilation member and configured to change a state of the ventilation member between a ventilation state and a closed state. A cover movably mounted on top of the lid, shiftable between a closed and an open position, comprises a cam on an inward surface of the cover which is configured to contact the vent actuator during movement of the cover member to change the state of the ventilation member. In the closed position the cover engages the straw, folding the straw against the lid, and in the open position, the straw fluid passageway and the vent opening are unobstructed.

A container latching system has an open container with a container lid with extended lip sections. Two slide lock latches are located over the lip sections on opposite sides of the lid. With the lid covering the container, the lip sections overlay the top edges of the container, the slide lock latches overlay a portion of the lip sections, and track slider members in each slide lock latch move along the lip sections to lock and seal the lid to the container.

An insulating container may include an opening, which can be sealed by a closure. The closure may have an upper portion with a handle that has a circular curvature equal to the cylindrical portion of the closure. The closure may also have a lower portion that is joined to the upper portion by an injection molded polymer element. The closure may also be in the form of flip type of closure such that the lid can be selectably opened or closed by the user by rotating a flip closure into either the opened or closed position. The closure may also be a two-part lid having a lower cap that may be configured to be removably-coupled to the container and an upper cap that may be configured to be removably-coupled to the lower cap

The present invention has the advantage of allowing a user to establish or release a seal between a container and a container lid with a single touch through a seal packing made of an elastic material and having a simple structure.

A food container with vents on handles includes a box and a cover. The box includes a box wall and a receiving room. Two opposite sides of the box wall are provided with a pair of handle portions. Each handle portion is extended with a bent section from the box wall toward a direction which is bent away from the receiving room. An upper portion of each bent section is formed with a venting space communicating with the receiving room. The cover is removably fastened to the box to cloak the receiving room and includes a cover plate, a pair of handle lids and sliding seals. The handle lids can be fixed to the handle portions to cover the venting space. Each handle lid is provided with vents. The sliding seals are separately disposed in the handle lids to be capable of selectively cloaking the vents.

A pickling device may include a housing having a first open end and a second closed end opposite the first open end. The housing may define a pickling cavity extending between the first open end and the second closed end, and the pickling cavity may be to receive food to be pickled. The pickling device may have a disc-shaped insert to be positioned in the pickling cavity and over the food to be pickled, a lid to be coupled to the first open end of the housing, and a positive pressure source to be removably coupled to the lid and configured to pressurize the pickling cavity during a pickling process without application of heat.

A drinking cup having a receptacle with an open end and a lid assembly configured for releasable engagement with the receptacle over the open end. A lid assembly wall has an inner surface and an inner ring extending radially inward therefrom. The inner ring defines a plurality of fluid passages. A seal assembly is configured to be retained by the inner ring, with the seal assembly being resiliently deformable between a sealed configuration and an unsealed configuration. In the sealed configuration, the upper lip sealingly engages the inner surface and fluid is prevented from flowing through a lid assembly volume defined between the lid assembly and the seal assembly. In the open configuration fluid is permitted to flow from the receptacle, through the plurality of fluid passages, and between a gap defined by a portion of the seal lip and a corresponding portion of the sealing surface.
