Abstract
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).
