3 Claims. (01. 150-10) The present invention relates to dispensers The pouch is made of any suitable material, adapted for use on various containers, and while but for the purposes herein disclosed it may be it may be employed for many purposes it is parmade wholly of vulcanized rubber.

For this reason the metal clips ll extend over the extremities of the mouth, as shown in Figure 5, thus forcibly closing the mouth at these points and avoiding the objectionable gap which would otherwise be present. The outer edge of the mouth portion may be provided with a bead l4 which covers the clips I I.

The essential distinction of the pouch here shown is that the mouth is distorted from normal open position to bring it to closed or distorted position. In the other forms of devices for this urpose, the mouth is in normal condition when closed. The advantage of the present device is that when the expansive force of the spring is relaxed by pressing the ends of the mouth together, the rubber will return to normal position. This makes a certain and positive opening of the pouch, eliminating all tendency of the mouth merely to buckle when the ends are pressed together.

What is claimed is:

1. A pouch formed of rubber or like elastic material having a mouth molded therein and normally standing in spread or open condition, and a spring stretching the mouth to bring the sides thereof together.

2. A pouch having a mouth formed of vulcanized rubber, which normally stands in open or spread position, and a tension device acting on the ends of the mouth and distorting it by bringing the sides together.

3. A pouch comprising a mouth portion of resilient material which in normal condition stands open, and a spring element tending to distort the mouth toward closed position with the sides in contact.
