A box cover for a portable airtight box, comprising an upper cover, a lower cover, a sliding plate, a reset spring, a pinching member, a lower cover plate, and a sealing ring, wherein the upper cover is fixedly connected to the lower cover, an accommodating space is formed between the upper cover and the lower cover, and the sliding plate is movably arranged within the accommodating space, wherein the reset spring is disposed between the sliding plate and the lower cover, wherein the sliding plate is capable of moving upward relative to the lower cover, wherein the pinching member is movably arranged on the upper cover, and the pinching member abuts against the sliding plate, wherein the lower cover plate is movably arranged at outer bottom of the lower cover, and the lower cover plate is fixedly connected with the sliding plate.

A press type sealable container includes a housing including an open-top wall structure defining a receptacle for receiving material to be stored; a cover designed to fit over the opening of the container and have a movable push-push type button. According to the disclosure, a toggle mechanism is used instead of a self-locking push switch in the press type sealable container, thereby enhancing the resistance to pressure of the press type sealable container and improving the durability of the overall structure. Accordingly, the technical problems of unsatisfactory holding strength, easy damage under excessive pressure exerted by the push-push type button and short service life are solved. Moreover, the toggle mechanism is simple to implement, good in reliability, and long in service life.

A sealing cover with a two-way embedding buckle mechanism includes an upper cover member, a lower cover member, a fastener, an elastic element and a handle member. The fastener has two embedded buckle channels corresponding to each other, each includes a sliding path, a first embedding port and a second embedding port. The first and second embedding ports are formed on two ends of the sliding path respectively. The elastic element is elastically clamped between the upper and lower cover members. The handle member includes a knob handle and two support arms, and each support arm has a shaft, and each shaft selectively enters one of the first and second embedding ports and is capable of moving in each sliding path. This arrangement may improve the convenience of assembling and disassembling.

A cap closing structure for a sealed container includes an upper cover, a lower cover, an elastic element and a handle member. The upper cover includes a top plate having a through hole and a circumferential bracket having a retaining slanted surface. The lower cover underneath the upper cover includes a base plate having a latch member penetrating into the through hole and a sealing ring. The latch member includes a guiding structure. One end of the sealing ring is at outer side of the retaining slanted surface. The elastic element is mounted onto the latch member and clamped between the top and base plates. The handle member includes a dial lever and an arm with a shaft operably moving inside the guiding structure for the sealing ring to be sealed between the retaining slanted surface and container.

A drink container and plug lid for use therewith. The lid has an upper member and a lower member with a ring seal positioned therebetween and radially outwardly stretchable from an initial diameter to a larger sealing diameter in response to an actuator moving the upper and lower members together to place the ring seal in fluid-tight sealing engagement with the container body. Moving the upper and lower members apart allows the radially outward stretched ring seal to move from the sealing diameter to the initial diameter whereat it is out of fluid-tight sealing engagement with the container body.

A storage container assembly includes a container having an opening and a lid for covering the opening. The lid includes a top lid, a button, a cam, a base, a lower plate and a gasket. The button is moveable in a first axial direction with respect to the top lid between a projected position and a depressed position. The cam is configured to cooperate with the button such that the button maintains the depressed position when moved from the projected position to the depressed position, and the button remains in the depressed position until pressed again while in the depressed position. The lower plate is connected with the top lid. The gasket is moveable between a contracted state and an expanded state in response to alternate actuations of the button, and the gasket is interposed between the lower plate and the top lid.

A storage container assembly includes a container and a lid. The lid includes a top lid, a button, a gasket, a gasket pusher, and an arm. The button is moveable in a first axial direction between a projected position in which a top surface of the button is offset from an upper surface of the lid and a depressed position in which the top surface of the button is nearer to the upper surface. The gasket is moveable between a contracted state and an expanded state. The gasket pusher is moveable in a second axial direction, which is transverse to the first axial direction, and pushes the gasket. The arm operatively connects the button with the gasket pusher. Movement of the button from the projected position toward the depressed position results in pivotal movement of the arm and moves the gasket pusher in the second axial direction.

A storage container or storage vessel is provided that includes an opening at its bottom or base. A lid element is provided at the bottom or base of the container/vessel that is movably mounted relative to an opening into the enclosed volume of the container/vessel. A clamping mechanism is associated with the body and lid of the container/vessel so as to releasably lock/secure the lid relative to the body. The body of the container/vessel features an aesthetically and/or artistically desirable shape or design that enhances the appeal and uniqueness of the container/vessel. The lid element of the container/vessel functions as the base of the container/vessel, thereby allowing the entirety of the body of the container/vessel (or such percentage as may be selected in a specific embodiment) to be incorporated into the aesthetically/artistically pleasing body design. A child-proof securement mechanism may be provided between the container and the lid element.

A storage container assembly includes a container and a lid. The lid includes a top lid, a button, a gasket, a gasket pusher, and an arm. The button is moveable in a first axial direction between a projected position in which a top surface of the button is offset from an upper surface of the lid and a depressed position in which the top surface of the button is nearer to the upper surface. The gasket is moveable between a contracted state and an expanded state. The gasket pusher is moveable in a second axial direction, which is transverse to the first axial direction, and pushes the gasket. The arm operatively connects the button with the gasket pusher. Movement of the button from the projected position toward the depressed position results in pivotal movement of the arm and moves the gasket pusher in the second axial direction.
