Multiple barrel dispensing device

摘要

A multiple barrel device for separate storage of viscous materials and for dispensing and intermixing same through a common static mixing element when pressure is applied. The device includes a multiple barrel syringe and a removable nozzle which is coupled to the syringe to form an interlock and a simultaneous pressure seal. The head of the syringe has a plurality of lugs which form bayonet grooves for engaging a complementary number of tong-like projections extending from the head of the nozzle. The head of the nozzle contains an annular bead which simultaneouly seals the interface at the intercoupling between the head of the syringe and the head of the nozzle.
