Dual separable dispenser

A dual separable dispenser for simultaneously dispensing two materials comprising a pair of single piece barrels of substantially equal length, each barrel having an outflow orifice at one end and an opening at the opposite end, there being a separable connection between the barrels along adjacent sides holding the barrels in fixed laterally separated parallel relationship forming a space therebetween with outflow orifices adjacent each other, a single piece plunger for each barrel, and a separable attachment between said plungers holding said plungers together in fixed laterally spaced relationship at one end of each while respective opposite ends are in sliding position in the corresponding barrels, said barrels being parallel to each other with said barrels and said plungers being separable allow each barrel and the respective plunger to be operated individuallv, the separable connection between the barrels being in said space and comprising a pair of complementary sliding members, each member being integrally formed with the respective barrel extending radially outwardly from the respective barrel and providing a stiffening means between the barrels throughout the length of said barrels.
