By providing a synthetic closure which comprises at least one thermoplastic polymer and, as an additive, at least one fatty acid derivative, in particular a fatty acid ester or a fatty acid amide such as a stearamide, a synthetic closure is attained which achieved substantially enhanced properties. In particular, it has been found that the oxygen transfer rate of the closure is reduced substantially, thus reducing unwanted oxidation of wine. Furthermore, the use of a fatty acid derivative additive improves the performance characteristics of synthetic corks, such as extraction force, ovality control, diameter control and length control.

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 a 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.

A method of preparing a closure for a product retaining container is disclosed along with the closure that is obtainable by the method. The present disclosure also relates to a use, in the manufacture of a closure, of a knife blade comprising a cutting edge region having a discontinuous cutting edge.

A closure assembly for a package with a flexible thin-walled bag which has a spout unit having a spout and at least one spout cam portion, and a closure applicable to the spout unit and having a cap that extends along a cap axis is provided. The cap has cap wall having a lower edge in which at least one cap cam portion is formed. The at least one cap cam portion is at least partly complementary to the at least one spout cam portion. In a disengagement configuration, by rotating the cap with respect to the spout about the cap axis, an interaction between the at least one cap cam portion and the at least one spout cam portion causes the cap to lift axially with respect to the spout.

A reclosable container for fluid products is provided. The reclosable container has a containment body provided with a neck ending in a dispensing mouth, and a closure member having a gripping element beneath which lies a stopper tip for closing the dispensing mouth and a removable collar associated with the gripping element along a preestablished break area and rigidly attachable to the neck. In a closed configuration, the dispensing mouth is completely covered by the closure member so that it is not possible for a user's fingers to come into contact with the dispensing mouth when opening the container, avoiding contamination of calibrated drops of the fluid products.
