ABSTRACT:
The end closure for the nozzle orifice of a dispensing cartridge for a two-component or multi-component system has at least two parallel stoppers which project from a common base and fit into the adjacent dispensing canals in the nozzle tube of the cartridge. For securing the closure to the cartridge in an axial direction, anchoring devices are provided to engage in the cartridge, such as lugs that permit elastic deformation, fitted with hooks or holding cams. At the junction with the base, each stopper has a continuous peripheral fillet. This acts conjointly with the edge of the orifice of the corresponding dispensing channel. The closure forms a secure seal for long-term storage and transport of the cartridge, is easy to use and inexpensive to make.
