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.

A thermoplastic elastomer composition including: 100 parts by mass of a hydrogenated block copolymer (a); from 10 to 50 parts by mass of a polypropylene resin (b); from 5 to 100 parts by mass of a polyphenylene ether resin (c); and from 75 to 200 parts by mass of a non-aromatic softener (d), wherein the hydrogenated block copolymer (a) contains a hydrogenated block copolymer (a-1) obtained by hydrogenation, the hydrogenated block copolymer (a-1) comprising at least one polymer block A1 including mainly a vinyl aromatic hydrocarbon compound monomer unit, and at least one polymer block B1 including mainly a conjugated diene compound monomer unit, a weight-average molecular weight of the hydrogenated block copolymer (a-1) is from 100,000 to 550,000, and a content of all vinyl aromatic hydrocarbon compound monomer units in the hydrogenated block copolymer (a-1) is more than 20% by mass and 50% by mass or less.

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.

A closing assembly for a bottle, the assembly including a cage, a closing stopper, and a ring nut. The cage includes a side wall with an inner surface including a bead and a lip spaced to form a seat for a collar of the bottle. Retaining teeth are provided for keeping a head of the closing stopper in position. An outer surface of the side wall of the cage includes an annular cavity and a side wall of the ring nut includes an inner lower projection configured to engage the annular cavity in a preassembly configuration. The cage further includes a plurality of windows. Each window includes a tongue connected to a lower edge of the window along a hinge line. The lip is formed at an upper end of each tongue and each tongue is rotatable elastically about the hinge line.

A method for manufacturing a closure constructed to be inserted and securely retained in a neck of a product-retaining container includes intimately combining a plurality of coated particles (each comprising a cork material core and a first plastic material) with a second plastic material, and other optional constituents; heating the composition to form a melt; extruding or molding a closure precursor from the melt; and optionally cutting and/or finishing the closure precursor. A composition for use in manufacturing a closure includes a plurality of coated particles (each comprising a cork material core and a first plastic material) with a second plastic material, and one or more blowing agents. Methods for producing particulate material, cork composite material, and additional method for producing closures are also provided.

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.

An apparatus for separating an interlocked cap and receptacle comprises a top wall and a cap removal station. The cap removal station comprises an opening, a raised collar for engaging and releasing interlocking elements of the cap and receptacle, and tabs on a side of the top wall opposite the raised collar for retaining the receptacle within the opening when the cap is separated from the receptacle. A method for separating an interlocked cap and receptacle comprises moving the cap and receptacle in a first direction into a cap removal station, contacting interlocking elements of the cap and receptacle with a raised collar to thereby release the interlocking elements, retaining the receptacle within the cap removal station; and with the interlocking elements released and the receptacle retained within the cap removal station, moving the cap in a second direction opposite the first direction to separate the cap from the receptacle.

A plastic body including a generally cylindrical upper portion having an open end configured for engagement with an automated pipettor. The plastic body further includes a plurality of longitudinally oriented ribs disposed on an inner surface of the open end of the upper portion and a plurality of concave recesses disposed on an outer surface of the upper portion. Each of the recesses is disposed directly opposite an associated one of the ribs, and each of the recesses extends along at least part of the length of the associated rib.
