Definitions

  • the inner surface of the cap base is covered radially inside the annular circumferential seal with an oxygen-absorbing compound which consists of a material which is chemically related to the material of the closure.
  • an oxygen-absorbing compound which consists of a material which is chemically related to the material of the closure.
  • Preferred materials for corresponding one-piece closures are, for example, polyethylene and polypropylene. Accordingly, the corresponding compound should predominantly consist of polyethylene or polypropylene, but which is additionally mixed or compounded with an oxygen-absorbing substance, it being understood that the material which directly absorbs oxygen and the main constituent or matrix constituent of the compound (i.e., e.g. Polyethylene or polypropylene) must be compatible.
  • FIG 2 is shown roughly schematically how the compound 4 is introduced and distributed in the closure.
  • a drop with a sufficient mass of the compound material in the hot, plastic state is generally applied in the center of the cap base and then the stamp 20, the outer contour of which is the inner contour of the Completely molded compounds corresponds, retracted into the cap and thereby pushes the hot, plastic compound material apart and distributes it in the space remaining between the stamp and the cap, which corresponds exactly to the shape of the compound 4 in Figure 1.

Abstract

L'invention concerne un capuchon (1) pour contenants, qui comprend une jupe (2) cylindrique et un fond (3), ainsi qu'un joint (5, 6) circonférentiel annulaire qui s'étend à partir de la surface intérieure du capuchon et est destiné à venir en contact, pour créer l'étanchéité, avec le corps du contenant, ce joint circonférentiel annulaire ne formant qu'une seule pièce avec le capuchon. L'objectif de l'invention est d'offrir une fermeture du type susmentionné qui, comme les fermetures en une seule pièce connues, soit facile à produire et à manipuler, et présente des caractéristiques d'absorption d'oxygène. A cet effet, la surface intérieure du fond (3) est revêtue d'une composition absorbant l'oxygène, à savoir d'une matière apparentée à celle constituant la fermeture.
