Systems and methods for storing a liquid include a container including a body portion defining an internal chamber and at least one opening in communication with the internal chamber, and an insertable plug including a plug body with two rings attached to the plug body via hinges, the insertable plug configured to be inserted into the opening so that a portion of the plug body covers a lip of the opening to restrict access through the opening to the liquid contained in the internal chamber, wherein the hinges can be deformed to raise the two rings away from the plug body. An insertable plug for a container can include a cylindrical plug body, and two rings attached to the plug body by hinges, wherein the hinges can bend to orient the rings towards or away from the plug body.

The stopper is equipped with a stopper main body having a guiding path extending in an axial direction. A stopper member has a flow path extending in the axial direction and is inserted in the guiding path of the stopper main body. A sealing member inserts into the flow path of the stopper member in such a manner as to block the flow path. The stopper member is equipped with, at a position where the sealing member is inserted, a first peripheral wall section fixed in a manner as to extend in the axial direction and a second peripheral wall section separated from the first peripheral wall section in a circumferential direction and extending radially outward along the axial direction.

A system and method for automatic closure of sample vessels such as vessels with medical laboratory samples, having a plurality of identically shaped, stackable closure caps with a convex outer face and concave inner face that are stacked in a closure cap stack such that an upper closure cap in the stack bears with its convex outer face on the concave inner face of a lower closure cap lying immediately below in the stack. The system includes a closure gripper for gripping an uppermost closure cap from the stack, for transferring the gripped closure cap to the sample vessel to be closed, and for introducing the gripped closure cap into an opening of the sample vessel in order to tightly close the opening. The closure gripper has a centering piece insertable into a closure cap such that it bears on the concave inner face of the closure cap.

A hermetically sealable container for liquids has a container body and a cap for closing a mouth of the container body. The cap has a main gripping body and a coupling appendage for insertion in the container body. An inner surface of a tubular container wall has a conical guide surface and an intermediate surface connecting the conical guide surface to a shoulder and defining a first annular prominence. The coupling appendage may be in contact with a head end against the shoulder to create a first sealing zone. When the head end abuts against the shoulder, the head end interferes with the first annular prominence, creating a second sealing zone. The coupling appendage has a second annular prominence protruding from a lateral coupling surface near a base of the coupling appendage. When the head end abuts against the shoulder, the second annular prominence interferes with the conical guide surface, creating a third sealing zone.

A beverage container that includes a main body portion having an open top, a closed bottom and an interior that defines a first volume, and a removable cover that includes a bottom and a generally cylindrical side wall extending upwardly from the bottom. The bottom and the generally cylindrical side wall cooperate to define a cover cavity, the removable cover is removably engaged with the main body portion, and the bottom includes a plug opening defined therethrough. A breathable plug is received in the plug opening. The plug allows a liquid disposed within the first volume to breathe with respect to an exterior of the beverage container.

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 that are formed after a threaded closure is inserted at least partially into the opening. The container opening may be selectively sealed and reclosed with the threaded closure which releasably engages the container threads.
