Cartridge for an extrudable mass

摘要

A cartridge dispenser for viscous material, e.g. sealant, has a shaped head (21) with sockets (25, 26) to take one or more packs (12, 16) of components which arte presses into a mixing head (231) and out of a dispensing port (23). The sockets are of different sizes and/or are shaped to fit correspondingly shaped/sized packs to prevent incorrect fitting. The components are dispensed in a preset mixture as determined by the shape and size of the packs.
