Foil cartridge and method for producing a foil cartridge

Abstract

A foil cartridge is disclosed. The foil cartridge has a foil tube enclosing at least one chamber in the circumferential direction and a cover separate from the foil tube. The cover closes an axial end of the foil tube. At least one first opening is configured in the cover for each chamber, through which opening the chamber may be filled with a filling material. A closure is provided, which seals the first opening. To produce the foil cartridge, the chamber is established by connecting the cover with the foil tube. Then the chamber is filled with a filling material through the first opening in the cover and the first opening is sealed.

What is claimed is: 
     
         1 . A foil cartridge, comprising:
 a foil tube defining a chamber in a circumferential direction;   a cover connected to the foil tube, wherein the cover closes a first axial end of the foil tube, wherein the cover includes an opening associated with the chamber, and wherein the chamber is fillable through the opening with a filling material;   a closure, wherein the opening is sealable by the closure; and   a base connected to the foil tube, wherein the base closes a second axial end of the foil tube.   
     
     
         2 . The foil cartridge according to  claim 1 , wherein the foil tube encloses a plurality of chambers and wherein the plurality of chambers are separated from each other by a partition of the foil tube in an axial direction. 
     
     
         3 . The foil cartridge according to  claim 1 , further comprising a second foil tube disposed within the foil tube, wherein the second foil tube defines a second chamber and wherein the second foil tube extends substantially parallel to the foil tube. 
     
     
         4 . The foil cartridge according to  claim 1 , further comprising a head section connected to the cover, wherein the head section has an outlet opening provided on a receptacle for a mixing tube for dispensing the filling material. 
     
     
         5 . The foil cartridge according to  claim 4 , wherein a channel for guiding the filling material to the outlet opening is disposed between the cover and an inner wall of the head section. 
     
     
         6 . The foil cartridge according to  claim 1 , wherein the cover further includes a discharge opening associated with the chamber. 
     
     
         7 . The foil cartridge according to  claim 1 , wherein the closure is a foil. 
     
     
         8 . The foil cartridge according to  claim 4 , wherein an edge of the opening in the cover and/or a filling opening in the head section have a conical taper. 
     
     
         9 . The foil cartridge according to  claim 4 , wherein a lip is provided on an edge of the opening in the cover and/or a filling opening in the head section. 
     
     
         10 . A method for producing a foil cartridge with a foil tube, a cover having an opening, and a base comprising the steps of:
 forming a chamber by connecting the cover and the base to the foil tube;   filling the chamber with a filling material through the opening in the cover; and   sealing the opening.   
     
     
         11 . The method according to  claim 10 , further comprising the step of connecting a head section to the cover before the filling step, wherein the head section has a receptacle for a mixing tube for dispensing the filling material. 
     
     
         12 . The method according to  claim 10 , further comprising the step of connecting a head section to the cover after the filling step, wherein the head section has a receptacle for a mixing tube for dispensing the filling material. 
     
     
         13 . The method according to  claim 10 , wherein the opening is sealed by a closure. 
     
     
         14 . The method according to  claim 10 , further comprising the step of inserting a filling lance through the opening into the chamber, wherein the filling step is performed via the filling lance in an immersed filling process.
