A can end including a central panel with an expandable bubble disposed thereon is provided. The use of an expandable bubble allows for an expandable rivet button and thereafter an expandable rivet that has an enhanced overlap of a tab body. Such an expandable rivet allows for the use of a metal sheet with a thinner base thickness.

Provided is an airtight container for positive pressure beverage that has a cap which is able to improve airtightness. The airtight container for beverage is provided with a beverage container and a cap. The beverage container has a body portion and a flange. The flange is continuous with an upper portion of the body portion and defines an orifice. The cap is attached to the beverage container so as to seal the orifice. The cap has a liner and an exterior body. The liner has a thin liner portion for sealing a lower side portion of the flange and a thick liner portion for sealing an upper side portion of the flange. The exterior body is fixed to the flange so as to cover the liner from an outer side, in order to seal the orifice together with the liner. The exterior body presses the thin liner portion against the lower side portion of the flange and brings the thin liner portion in close contact therewith.

Various apparatuses are disclosed. An apparatus may include a vessel configured to hold liquid, a cap detachably connected to an end of the vessel, and a mount connected to an opposite end of the vessel, wherein the liquid drains from the vessel only when the cap is detached. An apparatus may include a vessel configured to hold a liquid, a cap detachably connected to the vessel, and a mount connected to an exterior portion of the cap, wherein the liquid drains from the vessel only when the cap is detached. The liquid may include some alcohol. The vessel may be translucent and/or may include alcohol-tolerant material. Food substance may be mounted on the mount. The vessel may have the shape of a cylinder or polygonal prism. The cap may be a twist cap, a push-down-and-turn cap, a snap-top cap, a pull-tab cap, a push-on cap, or a tear-tab cap.

An easy-open metal end and a method for making same, in which a pre-score coining operation is performed, followed by an operation to form a score line. The coining step uses gentle-radius tooling designed not to crack or cut a protective coating on the metal end. Between the coining step and the score line-forming step, a paneling step is performed to pull out the loose metal generated in the coining step, such that end tension can be controlled more easily than in a conventional process. The coining operation thins the metal, so the score line can have less penetration than, and therefore can be narrower than, a conventional score line. Consequently, even if the score line does rust, it will be very small in width and thus relatively unnoticeable.

Various embodiments of a sealing member disposed between a container body and an endpiece attached thereto are disclosed, as well as a method for disposing a sealing member between an endpiece and a container body. In one embodiment, a sealing member is disposed within a space between a container body flange and a corresponding portion of the sidewall of the container body, is disposed between a space between an endpiece flange and a corresponding portion of an endpiece wall, and is further disposed between the endpiece flange and container body flange. As such, the sealing member has a generally S-shaped configuration in cross-section. At least one and preferably two scores are incorporated on the sealing member to facilitate at least a partial removal of the endpiece from the container body so as to be able to access the contents of the container. In another embodiment, a sealing member is removed from between the endpiece and container body, and at least one mechanical purchase exists between the endpiece and container body to provide a "reclosability" feature.

A plastic closure cap, especially for glass containers, includes a lid part to be pulled off exposing a seal or an opening. A sleeve part surrounds a bottle neck of the container. Grippers are secured on the sleeve part and are pivotal at material weak points at the sleeve part. The grippers abut one another in flush fashion in a closing position and are joined to make a closed surface encompassing the bottle neck. The grippers have sides pointing toward one another. The grippers are rectangular as seen in a plan view and curved as seen in cross section. Tabs are associated with the grippers. The sides of the grippers and the tabs face one another and have alternating profiling mutually complementing one another in the closing position. The sides of the grippers are beveled toward the inside and overlap one another in the closing position.

A cap blank for a bottle or jar comprising a disc formed with at least one depression. The depression provides a line of weakness when a cap formed from the blank is installed on a bottle or jar. A cap is also described. The cap can be removed from a bottle or jar by hand and is installed on conventional equipment for crimped tops, in the case of a bottle, or by hand or by conventional equipment for a jar.

A tamper-evident closure for a container comprises a center portion for overlying an open portion of a container, a seal portion, and a circumferential line of weakness surrounding the seal portion and defining a circumferential tear-strip. At least the tear-strip comprises deformable material. The tear-strip comprises a portion which creates a separation therein upon deformation when the closure is secured to a container. A method for applying the closure to containers is also disclosed.
