ABSTRACT:
A hermetically sealed container formed of a pliable material and which contains therein a substance capable of being ejected from within the container by application of a pressure force on the walls of the container. A band formed of a suitable material is mounted on the container at the discharge or exit end of the container, the band having a sharpened prong which is normally out of contact with one wall of the container, but which will engage with the wall of the container when pressure is applied on the walls of the container to thus cause container walls to expand and to force one of the walls into engagement with the sharpened prong to thus effect a puncturing of the wall to form an opening through which the contents of the container may be expelled.
