Open the CIPO recordAbstract From the Canadian patent
A spray pump comprising a main cylinder and a secondary cylinder with a main piston and a secondary piston, there being spring means urging the pistons to particular positions; there is a fixed attachment between the main piston and the secondary cylinder and the latter forms a space with a closed bottom and an open upper end through which the interior of the main cylinder and the space are in communication. The spring means may be exchanged freely and independently with the consequent greater versatility of the pump, the precompression of which prevents dripping and also a premature communication of the main cylinder with the outer air.
