The device comprises several layers 1-6, where an impermeable front layer (1) and an impermeable utility layer (6) together with a contact layer (2) will form the outer surfaces of the device (D), between which contact layer (2) and utility layer (6) are arranged a valve layer (3), a top layer (4) and a bottom layer (5). The top layer (4) and bottom layer (5) are connected to each other through a weld (11) in order to form a storage chamber (8) to accommodate a product. Furthermore, the valve layer (3) and top layer (4) are provided with a plurality of incisions or indentations (9a, 9b), where the incisions or indentations (9a) of the valve layer are welded to corresponding incisions or indentations (9b) of the top layer to form an opening mechanism in the device (D), where the device (D) is opened when the valve layer (3) is moved relatively to the top layer (4). ## Claims ### Claim 1 A device (D) containing a product, which device (D) comprises a front layer (1) and a utility layer (6) being welded over a part of their outer periphery to form an outer protective surface of the device (D), a contact layer (2) also being welded between the front layer (1) and utility layer (6), characterized in that a valve layer (3), a top layer (4) and a bottom layer (5) are arranged between the contact layer (2) and utility layer (6), the top layer (4) and bottom layer (5) being welded together by a weld (11) to form a closed storage chamber (8) in the device (D), each of the valve layer (3) and top layer (4) being provided with a plurality of incisions or indentations (9a, 9b), the incisions or indentations (9a) of the valve layer (3) being connected to the incisions or indentations (9b) of the top layer (4) by a weld (13) to form an opening mechanism in the device (D) and the bottom layer (5) being connected to contact layer (2) and/or to the utility layer (6), where the movement of the valve layer (3) relative to the top layer (4) will provide an opening of the incisions or indentations (9a, 9b) in the valve layer (3) and top layer (4). ### Claim 2 (depends on 1) Device according to claim 1, characterized in that a pocket layer (7) over a part of its outer edges is connected to the other layers (1, 2, 6), the pocket layer (7) together with the utility layer (6) thereby forming an opening for a user's hand or finger(s). ### Claim 3 (depends on 2) Device according to claim 2, characterized in that the pocket layer (7) is manufactured from an elastic material. ### Claim 4 (depends on 1) Device according to claim 1, characterized in that the incisions or indentations (9a, 9b) have a drop-shaped form. ### Claim 5 (depends on 4) Device according to claim 4, characterized in that the incisions or indentations (9a) of the valve layer (3) have a greater extend than the incisions or indentations (9b) of the top layer (4). ### Claim 6 (depends on 1) Device according to claim 1, characterized in that the valve layer (3) and the top layer (4) are provided with an equal numbers of incisions or indentations (9a, 9b). ### Claim 7 (depends on 1, 6) Device according to claim 1 or 6, characterized in that the weld (13) is comprised of a closed weld seam (13a) and a spot weld (13b). ### Claim 8 (depends on 1, 4, 6) Device according to claim 1, 4 or 6, characterized in that the incisions or indentations (9a, 9b) are only partly cut through the thickness of the valve layer (3) and top layer (4), thereby being connected or joined to the respective valve layer (3) and top layer (4) through a contact area (20). ### Claim 9 (depends on 1) Device according to claim 1, characterized in that the contact layer (2) has a surface with a degree of roughness. ### Claim 10 (depends on 1) Device according to claim 1, characterized in that the bottom layer (5) is joined or connected to the contact layer (2) through a weld (12). ### Claim 11 (depends on 1) Device according to claim 1, characterized in that the front layer (1), the contact layer (2) and the utility layer (6) are welded around their outer peripheries. ### Claim 12 (depends on 1) Device according to claim 1, characterized in that the storage chamber (8) is provided as a multi-chambered chamber.
