A self-sealing container, used for transferring one or more air sensitive samples between vacuum systems, includes a housing with a cavity that holds the sample(s), and a lid disposed on top of the housing. The lid is configured to interface with the housing to form a seal over the cavity when the lid is closed. At least two flexure systems, each coupled to the housing and the lid, are disposed on opposing sides of the housing. The flexure systems apply forces to the lid that move the lid horizontally and vertically above the housing, into an open position. A pneumatic actuator, movably coupled to the housing and the lid, that is actuated by a change in ambient pressure. When actuated, it applies forces that move the lid horizontally and vertically to the closed position, in opposition to and in excess of the forces applied by the flexure systems.

Systems, methods, and devices for sealing a container are described and disclosed. A system includes a lid assembly configured to seal an opening of a container and a coupler assembly configured to be disposed within a recessed portion of the lid assembly. The lid assembly includes a recessed portion configured to facilitate coupling the lid assembly with an external vacuum source. The lid assembly includes a hole disposed within the recessed portion and a ball seal disposed in the hole, wherein the ball seal is configured to seal the hole in a closed position when a vacuum pressure is created within the container. The lid assembly includes a gasket cavity disposed within the lid assembly, wherein the gasket cavity is configured to align a gasket for creating a seal between the lid assembly and the container. The coupler assembly includes a coupler body, a coupler seal, and a vacuum port.

A seal bottle assembly includes a bottle and a cap is removably mounted to the top opening of the bottle to seal the first room. The cap includes a radial hole defined radially therethrough. A switch unit includes a seal part located in the cap, and a control part located outside of the cap. When the control part is pushed toward the seal part, the pressure in the cap and the bottle is the same as that of outside of the bottle assembly so that the cap is removable relative to the bottle. When the control part is pulled away from the seal part and the seal part is moved to seal a communication between the first and second rooms. The pressure in the cap and the bottle is different from that of outside of the bottle assembly so that the cap is not removable relative to the bottle.

The present invention relates to and provides a glassware lid and a glassware with same. After food is heated, the lid is covered; a first end of the air hole sliding lid is turned so that the air hole is communicated with outside atmosphere to avoid forming a vacuum state inside; when the lid needs to be taken out, the first sliding parts and the second sliding parts continue to slide to separate the hoop from the glassware body, which is convenient to operate. The structure is compact and the arrangement is reasonable.

A closure (1) for a container comprising a connecting element (2) for connection of the closure to a container, a sealing device (3) for sealing the access to a container content and an interface (4) to an adapter having a coupling receptacle (5). The closure (1) has a delivery position and a use position. In the use position, the sealing device (3) is open. In the delivery position, the sealing device (3) is sealed in a gas and liquid fight manner.

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.

Aspects and techniques of the present disclosure relate to an internal cover/vent handle arrangement, in association with a container, such as a 5 gallon bucket with a slanted sidewall for evacuating air volume above stored material. The disclosure relates to a squeeze-actuated vent valve arrangement arranged and configured to be easily operated even while deeply recessed in the bucket. The disclosure also relates to a deflectable outer seal arrangement configured to seal against a slanted sidewall of a bucket.

A can for containing a liquid has a top end having a dispense area defined by a first score line and a pull tab coupled to the top end by a rivet. The pull tab has a puncturing end for breaking the first score line and pushing into the interior of the can without detaching the dispense area to open a dispense aperture. A vent area is defined by a second score line and positioned on the opposite side of the rivet. The first and second score lines are separated by at least one torsion stripe of the can top material for acting as a hinge by torsion upon lifting the actuating end of the pull tab. As the dispense aperture is opened by pushing the dispense area into the interior of the can, a vent aperture is opened by pulling the vent area outwards.

A dispensing closure for dispensing fluid product from a squeeze container consists of an outer cap element (3) and an inner element or valve disc (4) fitting inside the cap element. Each is moulded from thermoplastics; no elastomer is used. The cap element includes an outwardly-deflectable diaphragm wall (35) around a central outlet opening (361). The inner element (4) has a peripheral mounting ring (41), a central blocking portion (48) and a set of support spokes (46) providing flow clearance between them. In a closed position the blocking portion closes the outlet opening. In an outflow condition the diaphragm wall (35) deflects outwardly to allow flow. In a recovery mode the blocking portion (48) deflects inwardly for compensation air or residual liquid product to enter the container.

An insulating container can be configured to retain a volume of liquid, and include a first inner wall having a first end having an opening extending into an internal reservoir, and a second outer wall forming an outer shell. The opening can be sealed by a closure, the closure having 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.
