Title:
DRIP PREVENTION DEVICE IN A SEALER GUN
Document Type and Number:
WIPO Patent Application WO/2011/111644
Kind Code:
A1
Abstract:
When discharge of a liquid material has been stopped, the disclosed drip prevention device prevents dripping from the nozzle tip. A pump (P) comprising a cylinder (50) and a piston (51) is built into a sealer gun discharge tube (1). The pump (P) and the nozzle (10) are connected by means of a suction / discharge tube (5a). A grip member (4) and an actuating rod (61), which is connected to the piston (51) of the pump (P), are linked via a linking mechanism (6) such that the piston (51) slides in the cylinder (50) by means of the rotational action of the grip member (4), performing a suction / discharge pump action. When the grip member (4) is released and discharge of the liquid material is stopped, a negative or positive pressure is introduced inside of the nozzle by means of the pump action resulting from the grip member (4) rotating back to the original position.
