The invention concerns a plastic closure for fitting on to the neck of a liquid container in positively locking and sealed relationship comprising a head plate (1) provided for covering a container opening and an outer seal (7) which is circumferential along the edge of the head plate (1) and is provided for engagement with the outside of a container neck (20) defining the container opening, and an inner seal (5) which is circumferential within the outer seal (7) and parallel thereto and which is provided for engagement with the inside of the container neck, wherein the outer and the inner seals (7, 5) respectively extend approximately perpendicularly or slightly inclined from an inside (11) of the head plate (1). To provide a closure and also a container having a closure which generally prevent the closure being blown off under a high positive pressure it is proposed according to the invention that the outer seal (7) has a weakened region (6, 6, 6) in at least one circumferential portion so that the outer seal (7) becomes unsealed at a lower internal positive pressure than when the outer seal is of a configuration without the weakened region.

A beverage container includes a vessel and a stopper. The vessel includes a body with a neck portion. The body has an outer wall and an inner wall, and the neck portion defines an open end of the vessel body. The stopper selectively seals the open end of the vessel body in a closed, sealed position and selectively unseals of the open end of the vessel body in an open position. The stopper includes a body having an outer sidewall and a bottom wall. A seal is releasably connected to the body. The seal has a seal sidewall and a rim extending inwardly from the seal sidewall. The seal sidewall sealingly engages the outer sidewall and the rim sealingly overlaps the bottom wall. The outer sidewall together with the seal define an air pathway for the flow of ambient air into an interior of the vessel.

Disclosed are caps for closing an opening in a lid for a container, such as a paint can or bucket, wherein the caps comprises top walls comprising on their top surfaces centrally disposed recesses configured to receive a tool to rotate the caps; and threaded cylindrical projections on their bottom surfaces.

The present invention relates generally to a container that may be sealed and reclosed with a threaded closure. More specifically, the present invention relates to methods of manufacturing a metallic container having an opening with inwardly facing threads. The threads are formed on the metallic container by pressing a neck portion of the metallic container against closure threads of a threaded closure which is inserted at least partially into the opening. The container threads may optionally be formed while the threaded closure is in tension. In this manner, after the container threads are formed, the closure threads can apply a force to the container threads such that the threaded closure is in tension. The container opening may be selectively sealed and reclosed with the threaded closure which releasably engages the container threads. Novel apparatus and methods of sealing metallic containers and forming threads on the metallic containers are also disclosed.

A tank for containing e-liquid in an electronic cigarette assembly is disclosed. The tank comprises a cap and a body. The cap is connectable to the body through a screw thread with a specified handedness, and the body is connected to a battery assembly through a second screw thread with an opposite handedness to the screw thread of the cap. A construction of the tank ensures than when opening the cap, the body is not inadvertently unscrewed from the battery, and likewise when removing the body from the battery the cap is not inadvertently unscrewed from the body, thus preventing unintended e-liquid spillage and improving ease of removal of the cap and the body.
