Abstract:

A compressible cartridge includes a first flexible bag, a second flexible bag, and a rigid face plate. The first and second flexible bags include a multilayer film having at least three layers formed from different materials. The first and second flexible bags have a front end and a sealed back end opposite the front end. The first flexible bag defines a first volume to receive a first flowable material. The second flexible bag defines a second volume to receive a second flowable material that is different from the first flowable material. The rigid face plate has a first collar, a second collar, and a nosepiece. The first collar is bonded to the front end of the first flexible bag, and the second collar is bonded to the front end of the second flexible bag. The nosepiece defines 1) a first opening that is in fluid communication with the first volume of the first flexible bag, 2) a second opening that is in fluid communication with the second volume of the second flexible bag, and 3) a discharge opening.
