摘要

The spray cartridge distributes a mixture of two ingredients, e.g. resin and hardener or cement and binder, having a cylindrical housing divided by a partition into two chambers for the ingredients, while one or more pistons expel the ingredients from a nozzle. The partition (2) runs in the axial direction of the housing (1), and the piston is in two parts, each part (5,6) sliding in one chamber (3,4). The chamber outlets (9,12) lead to a common spray nozzle. The partition can be in the form of a tube, the interior of which (4) forms one of the chambers.
