  • Patent number: 7637679
    Abstract: A dispenser for dispensing a flowable material has a container having a side wall and further having a closed end and an open end. A membrane defines a chamber within the container between the membrane and the closed end of the container. The membrane has a weld seam rupturable upon the application of a force to a side wall of the container proximate the membrane. A swab assembly is operably connected to the open end of the container such that the swab assembly is in flow communication with the open end.

  • Publication number: 20090255953
    Abstract: A dispenser (10) for dispensing a mixture (6) of a first flowable material (4) and a second flowable material (5) has a container (12) having a first chamber (20) and a second chamber (30). The first chamber (20) is adapted to contain the first material (4) and the second chamber (30) is adapted to contain the second material (5). The dispenser (10) further comprises a first membrane (50a) separating the first and second chambers (20,30), and a second membrane (50b) connected to the container (12) proximate the second chamber (30). Pressure applied to the first membrane (50a) fractures the first membrane (50a) wherein the first flowable material (4) and the second flowable material (5) mix to form a mixture (6). Pressure applied to the second membrane (50b) fractures the second membrane (50b) to dispense the mixture (6).
