A container closure includes an outer cap, an inner cap, and a seal. The outer cap includes a top wall and an outer sidewall extending downward from the top wall. The inner cap is secured within the outer cap and includes a bottom wall and an inner sidewall extending upwardly from the bottom wall. The seal is secured to the inner cap and includes a seal sidewall and a rim extending inwardly from the seal sidewall. The seal sidewall sealingly engages the inner sidewall and the rim sealingly overlaps the bottom wall. The inner cap together with the seal define an air pathway in fluid communication between a space between the outer and inner caps and an air opening formed on the bottom wall of the inner cap and selectively covered by the rim.

The present invention relates to a container assembly for accommodating a beverage. The container assembly comprises a collapsible beverage container having a body part for accommodating the beverage and a cylindrical neck part defining a gas-filled headspace. The container assembly further comprises a closure sealing off an opening of the cylindrical neck part. The closure comprises a closure disc, an inner cylindrical part and an outer cylindrical part. The closure disc comprises a beverage outlet for extracting the beverage. The closure further comprises a pressure-relief device located at the closure disc or the inner cylindrical part. The pressure-relief device is capable of establishing a permanent or reclosable opening through the closure or between the closure and the neck part for allowing a flow of fluid from the headspace to an external space when a pressure difference exceeds a predetermined pressure value being lower than the burst pressure of the container.

A package is disclosed that includes a container and a closure. The container includes a container neck finish having a radially inner surface, a radially outer surface, and an axial outward end surface extending between the radially inner and outer surfaces. The radially outer surface includes a straight cylindrical upper portion and a threaded cylindrical lower portion. The closure includes a base wall engaging the axial outward end surface of the container neck finish, an external skirt extending away from the base wall and having a threaded section with internal threads engaging the container neck finish, and a pleated section between the threaded section and the base wall.

Provided is a lid of a fermented beverage container which has a gas discharge space part into which a transformation member transformed depending on a change in internal pressure of the fermented beverage container and has a through-hole so as to transfer the internal pressure of the fermented beverage container to the gas discharge space part to maintain airtightness while discharging carbonic-acid gas continuously generated from fermented beverage included in the fermented beverage container to the outside of the container.

A plastic closure embodying the principles of the present invention comprises a closure cap having a top wall portion, and an annular skirt portion depending from the top wall portion. The skirt portion includes an internal thread formation for threaded engagement with the external thread formation of an associated container. In order to facilitate high-speed application, and minimize the use of polymeric material, the closure is configured to exhibit a variation in retention force which decreases in a direction away from the top wall portion of the closure cap.

Container assemblies (100) that transition between a sealing state and a retained venting state are described. The container assemblies each include a body portion (110) having an open end (113), and a lid portion (120) adapted to cover the open end of the body portion to create an enclosed volume, e.g. reservoir, and additionally comprise a venting feature (140). When the fluid pressure within the enclosed volume is less than a threshold pressure, the lid portion is in a sealing state such that the lid portion and the body portion cooperate to maintain a substantially fluid-tight seal against fluid leaving the enclosed volume. When the fluid pressure is greater than or equal to the threshold pressure, the lid portion is in a retained venting state such that the excess fluid pressure from the enclosed volume vents through the venting feature while retaining the lid portion on the body portion.

A container system includes an outer container including a hollow interior, and a container insert positionable in the hollow interior of the container body. In one aspect, the container insert extends between a first end and an opposite second end and includes a generally cylindrical portion and an out-of-round portion positioned adjacent to the generally cylindrical portion. The out-of-round portion is enlarged relative to the generally cylindrical portion and configured to engage with a portion of the container body when the container insert is positioned in the hollow interior of the container body to provide a press fit between the container body and the container insert. In this or another aspect, the outer container includes a lateral opening and the container insert includes a flange which extends across at least a portion of the at lateral opening when the container insert is positioned in the hollow interior.

Described is one or more embodiments of closures that include a pressure-relieving feature in a third plug. In one embodiment, the pressure-relieving feature is a gap within the third plug. In another embodiment, the pressure-relieving feature includes one or more recesses within inner surface of the third plug, thereby providing fluid communication between an outer surface of the second plug and the ambient air outside the closure.

The invention relates to a cap for closing containers comprising at least one mesh, one foamed polymer and at least one further polymer, and to containers equipped with the cap of the invention.

A closure having a liner is provided. The liner forms one or more venting recesses that facilitate relieving pressure from a container to which the closure is affixed. In embodiments the liner extends from an outer surface of an annular wall through an outer disc of the liner.
