A container for a drink comprised of a bag of flexible plastic material for drink compacting sheets (1,2) welded upon each other by means of spaced longitudinal and transverse seams (3,4,5 and 6) which bag by means of a strip (7) or sheet (23) has been provided with a space for the insertion of a straw (13) such that the welding seams of said strip (7) or sheet (23) are either at a distance from the seams of the bag or coincide with said seams, an opening being provided for the insertion of the straw. The straw is movable within the space for puncturing the inside wall of the space which is elastically deformable and elastically surrounds the outer perimeter of the straw after it has punctured the wall. The straw may be removed if the contents of the bag are only partially consumed, thereby forming a seal by the punctured wall pushing against the outside wall of the space under pressure from the contents therein. The invention also deals with a method for manufacturing the bag by guiding a third sheet (23) into the path of the bag forming sheets (1,2).

Container for drink and method of manufacturing the container

Some chemical products are so toxic that they must not come into contact with parts of the human body. A package of such a construction that during filling and transport thereof and during the release of product therefrom, the risk of anyone coming into contact with the product is restricted to a minimum, is characterized in that the product is situated in a closed inner container (1) consisting of a water-soluble flexible material, and that the filled inner container is placed inside a closed outer container (2) consisting of a flexible material which is resistant to water, both the inner container (1) and the outer container (2) consisting of a flexible tube which is closed near the two ends by a transverse joint (4 or 5 respectively) and the end strips (6) of the inner container are connected to the joining strips (5) of the outer container in a manner such that between the contents of the inner container and the said joining strips there is a certain distance, and that a tear line (7) is made in an exposed part of one of the end strips (6) of the inner container (1).
