The cartridge also contains a head part for interacting with the film pouch. The film pouch has an opening on a side facing the head part which is closed by a cover. The insert is conical on a side facing the head part. A method can be used for producing such a cartridge. ## Claims ### Claim 1 A cartridge for a dispensing device, having: at least one non-rigid, elongate film pouch, which has a chamber for receiving a composition, a head part for interacting with the at least one non-rigid, elongate film pouch, and a rigid insert which is a different part from the head part, wherein the rigid insert is connected to the at least one non-rigid, elongate film pouch on a side facing the head part and has a passage closed by a cover, wherein the rigid insert is conical on the side facing the head part. ### Claim 2 (depends on 1) The cartridge according to claim 1, wherein a surface of the rigid insert facing the head part encloses an angle (ε) between 10° and 50° with a horizontal (H) perpendicular to the dispensing direction. ### Claim 3 (depends on 2) The cartridge according to claim 2, wherein the angle (ε) has a value between 15° and 35°. ### Claim 4 (depends on 3) The cartridge according to claim 3, wherein the angle (ε) has a value of 25°. ### Claim 5 (depends on 3) The cartridge according to claim 3, wherein the rigid insert has at least one ventilation opening that is independent of the passage and/or at least one ventilation slot that is independent of the passage, and/or wherein the passage of the rigid insert has at least one ventilation notch in a region facing a central axis of the at least one non-rigid, elongate film pouch. ### Claim 6 (depends on 2) The cartridge according to claim 2, wherein the rigid insert has at least one ventilation opening that is independent of the passage and/or at least one ventilation slot that is independent of the passage, and/or wherein the passage of the rigid insert has at least one ventilation notch in a region facing a central axis of the at least one non-rigid, elongate film pouch. ### Claim 7 (depends on 1) The cartridge according to claim 1, wherein the cover has a predetermined breaking region. ### Claim 8 (depends on 7) The cartridge according to claim 7, wherein the rigid insert has at least one ventilation opening that is independent of the passage and/or at least one ventilation slot that is independent of the passage, and/or wherein the passage of the rigid insert has at least one ventilation notch in a region facing a central axis of the at least one non-rigid, elongate film pouch. ### Claim 9 A cartridge for a dispensing device, having: at least one non-rigid, elongate film pouch, which has a chamber fir receiving a composition, and a head part for interacting with the at least one non-rigid, elongate film pouch and having a rigid insert, wherein the rigid insert is connected to the at least one non-rigid, elongate film pouch on a side facing the head part and has a passage closed by a cover, wherein the rigid insert is conical on the side facing the head part, wherein the rigid insert has at least one ventilation opening that is independent of the passage and/or at least one ventilation slot that is independent of the passage, and/or wherein the passage of the rigid insert has at least one ventilation notch in a region facing a central axis of the at least one non-rigid, elongate film pouch. ### Claim 10 (depends on 9) The cartridge according to claim 9, wherein the rigid insert has at least one ventilation opening that is independent of the passage and/or at least one ventilation slot that is independent of the passage, and/or wherein the passage of the rigid insert has at least one ventilation notch in a region facing a central axis of the at least one non-rigid, elongate film pouch. ### Claim 11 (depends on 1) The cartridge according to claim 1, wherein the rigid insert and the head part each have, in a mutually facing region, an interacting and substantially diametrically opposed contour, wherein the cover that is arranged in a region of the contours is weldable. ### Claim 12 (depends on 11) The cartridge according to claim 11, wherein the rigid insert has at least one ventilation opening that is independent of the passage and/or at least one ventilation slot that is independent of the passage, and/or wherein the passage of the rigid insert has at least one ventilation notch in a region facing a central axis of the at least one non-rigid, elongate film pouch. ### Claim 13 (depends on 1) The cartridge according to claim 1, wherein the at least one non-rigid, elongate film pouch is formed by a cylindrical film tube which is closed at a bottom by a base part. ### Claim 14 (depends on 13) The cartridge according to claim 13, wherein the base part is glued and/or welded to the cylindrical film tube. ### Claim 15 (depends on 1) The cartridge according to claim 1, which comprises at least two of the covers, at least two of the inserts, and at least two of the film pouches. ### Claim 16 A method for producing a cartridge for a dispensing device, having: at least one non-rigid, elongate film pouch, which has a chamber for receiving a composition, and a head part for interacting with the at least one non-rigid, elongate film pouch and having a rigid insert, wherein the rigid insert is connected to the at least one non-rigid, elongate film pouch on a side facing the head part and has a passage closed by a cover, wherein the rigid insert is conical on the side facing the head part, the method comprising: providing the at least one non-rigid, elongate film pouch having the chamber, wherein the at least one non-rigid, elongate film pouch is connected to the rigid insert and the base part, the rigid insert having an opening, filling the chamber with the composition through the opening, and closing the opening with the cover. ### Claim 17 (depends on 16) The method according to claim 16, wherein a predetermined breaking region is produced in a region of the cover. ### Claim 18 (depends on 17) The method according to claim 17, wherein the predetermined breaking region of the cover is produced by a laser, by weakening by hot stamping, by scoring, or by welding the cover to the insert. ### Claim 19 (depends on 16) The method according to claim 16, wherein the insert has at least one material extension. ### Claim 20 (depends on 19) The method according to claim 19, wherein the at least one material extension surrounds the opening, and wherein the at least one material extension melts during the closing of the opening.
