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.

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.

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 container assembly includes a container body enclosing a cavity, and first and second openings in the body that communicate with the cavity. A compartment is dimensioned for receipt through the first opening into the body cavity and partially fills the body cavity. The compartment housing is formed of a pliable, fluid sealable material open at a first end, and the housing receives a closure member also formed of a pliable, fluid sealable material to form a fluid-tight connection with the first end of the housing. The compartment includes an external shoulder dimensioned that limits further advancement of the compartment through the first opening and into the body cavity. A cap is dimensioned for receipt over the first opening of the body to selectively open and close access to the body cavity, and access to the compartment. A plug member is dimensioned for operative engagement with the second opening of the body for selectively opening and closing access to the body cavity.

A closure assembly (20) that includes a cap or overcap (28) and a fitment (24) for a container is provided wherein the fitment (24) has a laterally projecting shear member (40), and the overcap (28) has an aperture (74) for initially receiving the shear member (40) when the overcap (28) and fitment (24) are in an initially assembled orientation or condition. The aperture (74) and the shear member (40) cooperate in the initially assembled orientation such that when subjected to a flow of a sterilizing gas, turbulence is created in the sterilizing gas flow to enhance sterilization of the combination. The closure assembly (20) may, instead, or additionally, be provided wherein the overcap (28) has an elongate, hollow plug (58) for establishing a first seal between the fitment (24) and the overcap (28) in the initially assembled orientation, and the wherein overcap (28) has a skirt (50) for establishing a second seal between the fitment (24) and the overcap (28) in the initially assembled orientation.

A container comprising: a container body that includes a wall portion separating inside and outside and is formed of a long-fiber-reinforced silicon-carbide composite material obtained by combining monofilaments of silicon carbide with a silicon carbide matrix, the wall portion having a thickness equal to a specific dimension; and a lid configured to close an opening of the container body, formed of a material containing at least silicon carbide, and equipped with such a wall portion separating inside and outside that thickness is within a range of 1 to 3 times the specific dimension.

Embodiments of a device for protecting and sealing the opening of a container. This device is a one-piece made plug for a flask or container, comprising at least one passing channel, and at least one structural flow regulator barrier, allowing the passing of solid elements. The structural regulator barrier comprises at least a gate to regulate the passing and connection between the inside space and the outside space of the container in a unidirectional and/or bidirectional way. An embodiment includes a method and a mold for manufacturing such a device.

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.
