Abstract (en)
[origin: WO2022219176A1] The invention relates to a can containing a solid, liquid and/or gaseous medium that can have an overpressure or that can develop an overpressure during transport or storage, wherein the cylindrical can sleeve (101) of the can consists mainly of paper or cardboard material and comprises at least two wound layers and is closed at the bottom with a base element (4) and at the top with a cover element (5), wherein the innermost layer of the can sleeve (101) consists of a straight-wound barrier layer (102) which has with it a longitudinal seam running in the longitudinal direction of the can (1), wherein the longitudinal seam is sealed off on the inside by a film sheet of the barrier layer (102), which film sheet once overlaps the barrier layer (102) in the region of the longitudinal seam, or the longitudinal seam is sealed off by a sealing strip (110) extending straight in the longitudinal direction of the can, or the longitudinal seam forms a thickness increase, and the inner or outer longitudinal edge of a further layer (103, 104) of the can sleeve (101) in the form of a wound layer of paper or cardboard material lies facing the flank of the thickness increase.
