1. A cartridge for a dispensing device, having:
at least one first non-rigid, elongate film pouch, which has a chamber for receiving a first composition,
at least one second non-rigid, elongate film pouch, which has a chamber for receiving a second composition,
a head part for interacting with the at least one first non-rigid, elongate film pouch and the at least one second non-rigid, elongate film pouch and having a first rigid insert, the first rigid insert being connected to the at least one first non-rigid, clongate film pouch on a side facing the head part, the head part further having a second rigid insert, the second rigid insert being connected to the at least one second non-rigid, elongate film pouch on a side facing the head part,
a first connecting device which can connect the first rigid insert to the head part in a form-fitting and/or force-fitting manner, and
a second connecting device which can connect the second rigid insert to the head part in a form-fitting and/or force-fitting manner,
wherein the first rigid insert and the second rigid insert each have at least one first connecting element of the connecting device and the head part has at least one second connecting element of the connecting device,
wherein the at least one first non-rigid, elongate film pouch and the at least one second non-rigid, elongate film pouch are each formed by a cylindrical film tube which is closed at a bottom by a base part,
wherein the first connecting device comprises a completely surrounding latching lug which connects with a corresponding counter element of the first connecting device, such that a sealing connection can be achieved,
wherein the head part further comprises a first expansion space and a first outlet channel having a first diameter for outflow of the first composition from the first non-rigid, elongate film pouch at a first flow rate, and
wherein the head part further comprises a second expansion space and a second outlet channel having a second diameter different from the first diameter for outflow of the second composition from the second non-rigid, elongate film pouch at a second flow rate different from the first flow rate.
