Packaging

Abstract

The invention relates to packaging having an essentially dimensionally stable, elastically deformable external container in which an easily deformable inner bag receiving the filling goods is arranged, and a valve. Said packaging is characterised in the fact that the valve comprises: a base body which extends over the opening of the external container, said base body comprising at least one through opening for the filling goods and a valve maintaining element in which a valve body, which comprises an elastically deformable separating wall and which tightly seals the valve maintaining element, is fixed, and a valve journal pointing away from the external container.; Said separating wall together with the valve maintaining element delimits an air chamber, also comprising a cap covering the base body and the valve body secured to the neck of the external container, said cap delimiting a receiving chamber for the filling goods between the cap and the base body and has an outlet for the filling goods. When the packing is in the unpressurised state, said outlet is closed by the valve journal which is applied, by pre-stress of the elastically deformable separating wall on which the area of the cap contains the outlet. When pressure is applied to the external container, the valve journal is separated from the cap by the pressurised filling goods in the receiving chamber so that the filling goods can exit.; The packaging is characterised in that the cap comprises an air chamber separated by the receiving chamber for the filling goods, and sealed with respect to the receiving chamber and the external container, said air chamber is connected to the intermediate chamber between the external container and the inner container by means of at least one hole through the wall of the external container and to the exterior atmosphere by means of at least one aeration valve.

Description

technical field [0001] The invention relates to a package having a substantially dimensionally stable, at the same time elastically deformable outer container, an easily deformable filling-receiving inner bag arranged in the outer container and having a valve, which when pressure is applied to the outer container When on, the filling is released through the opening of the valve. This is a so-called airless system, in which no air enters the inner bag after the filling has been released, but air enters the space between the outer container and the inner bag from the outside atmosphere , the inner bag is squeezed progressively and remains in this state until the entire filling is expelled from the package, also known as a squeeze bottle. Background technique [0002] A large number of such packages are known. For example DE 102 17 655 A1 discloses a package in which a valve has a membrane with a sleeve-like projection surrounding a plug of a base body extending over the open...

AI Technical Summary

Problems solved by technology

When such a package is applied to a liquid filling, the following situation may occur: when the filling is discharged, the sleeve-shaped section of the membrane locally adheres to the stopper of the base body, which leads to The jet of liquid is not discharged in the longitudinal direction of the outer container, but in an oblique direction, so that the packaging is only suitable for the discharge of liquid fillings to a limited extent
