An auto-lock sealing valve structure of a rubber jointing ring using the lid attached to the rubber jointing ring includes a lid, a rubber jointing ring, and a bottle body. The rubber jointing ring connects the lid and the bottle body. The designation of the vapor escaping groove in the lid body helps the air inside the rubber jointing ring escape out, simultaneously the raised edge on the bottle lid prevents the rubber jointing ring part from coming out off. The gaps on the body part of the rubber jointing rings help the air inside the bottle body to entirely escape but still ensure that the liquid inside the devices cannot escape.

Vacuum stopper and assembly of stopper and container. There is disclosed a vacuum stopper (1) configured to be positioned into a neck (9) the neck of the bottle, the stopper comprising: a resilient shoulder (4) provided at an upper end of the elongated body (2), wherein the resilient shoulder is arranged for resting onto an upper side of the neck of the bottle; a stop ring (5) provided at an upper end of the elongated body above the resilient shoulder; a valve arranged (6) inside of the elongated body for allowing, in use, air to be sucked out of the 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.

An article for performing a reaction includes a reagent well having a side wall, a bottom wall and an open upper end. A lyophilized reagent is retained within the well by a non-integral retention feature that is inserted into the open upper end of the well and fixed to a side wall above the reagent. An opening in the retention feature is smaller than the diameter of the reagent, but is sized to permit a pipette tip to be inserted into the well. The retention feature may be a collar fixed to the side wall and may include fingers extending axially into the well. The well and the retention feature may be correspondingly tapered. A method for reconstituting a lyophilized reagent includes the steps of drawing into a pipette tip attached to an automated pipettor an amount of a diluent and dispensing the diluent into the reagent well to thereby reconstitute the lyophilized reagent.

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.

The disclosure relates to a synthetic closure for a product-retaining container constructed for being inserted and securely retained in a portal-forming neck of said container, said closure comprising at least a core member comprising at least one thermoplastic polymer, and at least one peripheral layer at least partially surrounding and intimately bonded to at least one surface of the core member, said peripheral layer comprising at least one thermoplastic polymer, wherein the synthetic closure is formed by extrusion, and at least one of the core member and the peripheral layer comprises a plurality of cells, and wherein the synthetic closure comprises cork powder.

A stopper has a head part and a stopper part. The stopper part extends from the head part to a lower end and has flanges, between the head part and the lower end, that have different diameters that increase from the head part to the lower end of the stopper part. A container has a mouth and neck and shoulder inner surfaces. The stopper part is inserted into the container through the mouth, the head part remains outside the mouth, at least one of the flanges proximate neck sealingly engages the neck inner surface, and at least one of the flanges proximate to the shoulder sealing engages the shoulder inner surface. A fluid tube is retained by the stopper. The fluid tube extends from an inlet within the container outwardly through the mouth to an outlet outside the container.

Apparatuses and methods of operating the same are described. A container lid adapter including a gasket, an adapter lid, and a container band. The gasket may be shaped to attach to a rim of a container to form a seal between the rim and the gasket. The adapter lid may include an opening shaped to receive an adapter. The container band may be shaped to attach the gasket and the adapter lid to the rim of the container.

A receptacle includes an upper portion having a cylindrical portion and an open end and a lower portion depending from the upper portion, where the lower portion is tapered and has a closed bottom end. The receptacle may include a radially-extending annular ring with a flat or sloped bottom surface and disposed on an outer surface of the receptacle at a transition between the upper portion and the lower portion and/or a radially-projecting lip circumscribing the open end, which may be configured for inter-locking engagement with a mated cap inserted into the open end of the upper portion. Embodiments may include one or more longitudinally-oriented grooves formed in an inner surface of the upper portion. The receptacle may be a unitary plastic structure.
