Abstract: The invention relates to a method for producing a vessel closure for vessels comprising an opening that is to be closed by the vessel closure, an inner diameter of more than two cm and surrounds a polymer-based sealing element that is arranged in the vessel closure in such a manner that is sealingly rests on the opening of the vessel in the closed state. A polymer material becomes sufficiently free-flowing by warming and is applied to the vessel closure in the region of the sealing element that is to be produced, and optionally, is mechanically formed into the desired shape which it maintains after cooling. The invention also relates to a metal or plastic vessel closures for vessels for receiving drinks or food, and comprises a sealing insert, the material thereof being selected so that the migration of material components into the drink or food, that are a health risk, is prevented.

Abstract: The invention relates to a polymer compound for a sealing insert for a container closure, in particular for fat-containing filling materials, which has a composition such that the migration of constituents of the compound into the filling material is reduced, characterized in that the Shore A hardness of the polymer compound is between 45 and 95 and in the compressive deformation test analogous to ASTM D395-97 Method B at 70 DEG C the polymer compound exhibits a compression set of 30-90%.

Abstract: Potable liquid containers including a container, container closure and a closure liner, where the closure liner is formed from a polymeric heterogeneous blend of unvulcanized and uncrosslinked butyl rubber and a thermoplastic polymer are described. The closure liners are used for containers with closures such as a twist crown, a crown cork or a screw cap, for bottles, jars and the like, and more specifically for beer, juice and soft-drink bottles with closures made of metal or plastics.

Abstract: The invention relates to a polymer compound for the production of sealing elements for vessel or container closures, which sealing elements when closed have a barrier effect preventing the penetration of gaseous or vaporous substances such as oxygen or aromatic compounds, in particular benzenes, phenyl ethers and suchlike into the vessel and/or show an excess pressure valve effect at interior vessel pressures of between approx. 3 and 10 bar and may be produced by mechanical forming of the unshaped thermally plastified polymer compound and its subsequent hardening directly on or in the vessel closure ("in shell" moulding), comprising a mixture of butyl and/or acrylate rubber and a polymer of an .alpha.-oleflnic unsaturated monomer as well as, if appropriate, one or several further polymer components and common additives such as glide enhancers, pigment, talcum and stabilizers. The invention further relates to a sealing element of this kind and a corresponding vessel or container closure.
