The present disclosure provides a container sealing plug. The container sealing plug including a plug body. The plug body is configured to seal a receiving opening of a container. The plug body includes a sealing part. The sealing part is configured to seal the receiving opening of the container. The sealing part is provided with a flexible sealing ring. The sealing ring is configured to press an inner wall that seals the receiving opening of the sealed container. A user can place food, liquid, or other objects into the container through the receiving opening of the container, and then seal the receiving opening of the container through the plug body. When the flexible sealing ring of the plug body is inserted into the receiving opening of the container, the inner wall of the receiving opening presses the flexible sealing ring.

System, apparatuses, and methods for performing automated reagent-based analysis are provided. Also provided are methods for automated attachment of a cap to a reaction receptacle, and automated removal of a cap from a capped reaction receptacle.

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.

System, apparatuses, and methods for performing automated reagent-based analysis are provided. Also provided are methods for automated attachment of a cap to a reaction receptacle, and automated removal of a cap from a capped reaction receptacle.

The present disclosure relates to the field of bottle stopper devices, and in particular, to a quick opening and closing container stopper, which includes a fixed shell and a movable stopper body. The fixed shell is provided with a dodging opening. The movable stopper body is provided with a limiting plate. An elastic sealing sleeve abuts against and between the limiting plate and the fixed shell. A knob is rotatably connected to the movable stopper body. The knob includes a side lug. When the container stopper is in a locked state, the side lug extends beyond a contour range of the dodging opening, and the fixed shell and the limiting plate are close to each other and drive the elastic sealing sleeve to bulge outward. When the container stopper is in an unlocked state, the side lug is accommodated in the dodging opening.

A closure device for a container to provide a combined protection of inert gas and oxygen scavenger methods. The closure device comprises a body, a fastening member, one or more plurality of protrusions, a blister, a hollow shaft, and a seal member. The closure device is removably coupled to an open end of the container through a fastening assembly. The fastening assembly includes at least one of friction fit, a snap fit, a screw fit, or any of a variety of fastening mechanisms. The closure device provides a combined protection of inert gas and oxygen scavenger methods. This is beneficial because it prevents nutritional and organoleptic degradation processes of wine through oxidation while aids to preserve the fruitier and fresher aromas and flavors of the wine. The closure device is designed to fit snugly over the neck of the bottle and create an airtight seal.

The present disclosure provides a container sealing plug, which includes a plug body and a first flexible member connected. The plug body configured to seal a receiving opening of a container body. The first flexible member connected to the plug body and having a first sleeving opening formed thereon, the first sleeving opening being configured to connect to the container body. A user can place food, liquid or other objects into the container body through the receiving opening of the container body, and then seal the receiving opening of the container body with the plug body, whereby air or water is effectively prevented from entering or leaking out the container body through the receiving opening of the container body and thus the long-term storage and freshness preservation of the content is guaranteed.

A cap having a lower portion, an upper portion with an opening formed therein, and a plurality of longitudinally oriented ribs disposed on an inner surface of the cap. The inner surface of the cap is defined by the opening formed in the upper portion of the cap, and each rib is associated with a concave recess disposed directly opposite the rib on an outer surface of the upper portion of the cap. The recess extends along at least part of the length of the rib.

A tube seal cap assembly for use with a product tube having a top wall and a nozzle comprises a primary cap and a gripper ring. The primary cap includes a top end and a bottom end. The gripper ring is operatively connected to the primary cap proximate the bottom end, and the gripper ring and the primary cap include mating features configured and arranged to prevent rotation of the gripper ring relative to the primary cap. The gripper ring includes at least one inwardly extending protrusion. In use, when the tube seal cap assembly is operatively connected to the product tube, the primary cap is configured and arranged to receive the nozzle and the at least one inwardly extending protrusion is configured and arranged to carve into the nozzle.

A sealed pharmaceutical container comprises a flange comprising an underside surface, an outer surface extending from the underside surface, the outer surface defining an outer radius r.sub.o of the flange; and an upper surface extending between the outer surface and an inner surface defining an opening in the sealed pharmaceutical container. The upper surface comprises a sealing region extending between the opening and the outer surface and comprising a radius r.sub.sr that is less than r.sub.o. The sealed pharmaceutical container also comprises a sealing assembly comprising sealing portion in contact with the upper surface at a lower surface of the sealing portion and a cap compressing the stopper against the upper surface. After compression, the sealing portion of the stopper comprises a compressed radius r.sub.sc that is less than r.sub.sr adjacent the upper surface.
