A dispenser () for dispensing flowable materials has a container assembly () having a dividing wall (). A first chamber () and a second chamber () are defined in the container assembly (). The first chamber () is configured to contain a first flowable material (M1) () and the second chamber () is configured to contain a second flowable material (M2) (). A membrane () is positioned in the container and cooperates with the dividing wall () to enclose the first and second chambers (). The membrane () has a first section () having a first weld seam () and a second section () having a second weld seam (). The first section () is separated from the second section () by a non-rupturable member (). Rupture of the membrane () allows the flowable materials into a third chamber () in which the flowable materials mix to form a mixture, and from which the mixture is dispensed. 1. A dispenser for dispensing flowable materials , the dispenser comprising:a container having an outer wall, a dividing wall and a membrane operably connected to define a first chamber and a second chamber, the dividing wall connected to the membrane at an interface, the first chamber configured to contain a first flowable material and the second chamber configured to contain a second flowable material,the membrane having a first section having a first, rupturable member and a second section having a second rupturable member, the first section separated from the second section by the interface.2. The dispenser of wherein the first rupturable member is a first weld seam.3. The dispenser of wherein membrane has a thickness and the first weld seam has a thickness less than the thickness of the membrane.4. The dispenser of wherein the first weld seam comprises a plurality of weld seams.5. The dispenser of wherein the weld seams extend radially from proximate a midpoint of the interface.6. The dispenser of wherein the second rupturable member is a second weld seam.7. The dispenser of wherein the membrane has a ...
