Squirt cartridge for mixing and dispensing a two-component mass

Squirt cartridge for mixing and dispensing a fluid mass of two components, including a mixing tube having an axis and an open end, a cylindrical casing coaxial with said mixing tube for containing a first component of said mass in which a dispensing piston is held, when said casing is filled, adjacent to a first end of said casing, said piston having, on its face directed away from said first casing end, means for sealing the open end of said mixing tube, said open end of said mixing tube and said means for having corresponding mating surfaces for fitting tightly against one another, said mixing tube having an interior chamber for containing a second component of said mass, and further comprising:

• a flat mixing plate mounted on said mixing tube at right angles thereto and adjacent to but axially spaced from the open end of said tube said mixing plate having a fitting against said piston, when said open end is sealed by said means for sealing, said mixing plate comprising arms extending away from said mixing tube to which mixing vanes are attached at one side of said arms in a position offset from said mixing tube by attachment means permitting a flapping movement of said vanes a predetermined maximum angular magnitude of deflection said arms and said mixing vanes having stop means at said attachment means for limiting the flapping movement of said mixing vanes to about axes of swing defined by said attachment means.
