Self-opening closure for composite packagings or for container or bottle nozzles for sealing with film material
First Claim
1. A self-opener closure for composite packagings or for container spouts to be closed with film material, comprising:
- a pour-out spout capable of being sealingly assembled onto a composite packaging, a container spout or bottle spout closed with a film material;
rotary cap for said pour-out spout; and
,a self-opener sleeve within said pour-out spout, said self-opener sleeve being rotatable via said rotary cap, and having at a lower edge and projecting from said lower edge of self-opener sleeve, least one combined piercing and cutting member, said self-opener sleeve, said pour-out spout and said rotary cap being equipped with guide and transmission means cooperating with one another, so that upon rotating said rotary cap for an initial time in a direction for opening, said self-opener sleeve is pushable axially downwards in said pour-out spout, the initial time, being without rotation, and for subsequent times, following the initial time, being rotatable about a rotary axis of said self-opener sleeve without axial movement.

Abstract
The self-opener closure consists of a pour-out spout (2) which may be sealingly assembled onto a composite packaging or onto a container spout or bottle spout to be closed with film material, of an associated rotary cap (1) as well as a self-opener sleeve (3) arranged within the pour-out spout (2) which may be set into rotation by the rotary cap (1). Force transmission means and guide means are formed on these three elements. These cooperate with one another such that on rotating the rotary cap (1) in the opening direction for the first time the self-opener sleeve (3) firstly in the pour-out spout (2) may be pushed vertically downwards and subsequently may be rotated by approximately 360° in the horizontal. Because the self-opener sleeve (3) at its lower edge and projecting from this comprises a single, combined piercing and cutting member (9) the film or the composite packaging is first reliably pierced and afterwards a disk is cut cleanly out of it and pivoted downwards.
