Abstract:
A dispenser head (10) of a trigger dispenser device includes a self-bearing pre-compression valve (80), made of polypropylene, capable of per se retaining in a stable manner to the head frame (14″).
Abstract:
A trigger dispenser device (1) is for dispensing a liquid comprises a container (C) and a dispenser head (20). The head includes a frame (22) having a pressure chamber (24) and a secondary liquid aspiration duct (50), and an auxiliary body (2) attached to the frame (22). The auxiliary body is provided with a primary liquid aspiration duct (8) and an air aspiration chamber (4b). Between the frame (22) and the auxiliary body (2) a merger compartment (64) is formed and the air aspiration chamber (4b) surrounds the merger compartment (64) so as to seal it.
Abstract:
A trigger dispenser (1) for liquids comprises a suction valve (30) and a delivery valve (60), separate from the suction valve (30). The dispenser (1) has a detachable stop (100), comprising a bottom (104) positioned rearwards of the delivery valve (60) to form an end stop abutment with this during the dispensing step.
Abstract:
A portable, manually operable, trigger-activated pump spray applicator can be used to apply paints and coating fluids in commercial and military end use applications, especially chemical agent resistant coating (CARC) fluids. The applicator includes an impermeable, preferably rigid-walled, container capped by a manually operable spray pump with a single fluid nozzle. The assembly has capability of producing an atomized spray of viscous coating fluids. The applicator includes internal agitators suitable to redisperse solid components of the coating fluid that settle after long-term storage. The agitators include a plurality of small, heavy spheres and a single large, heavy, striker. The inside bottom wall and side wall meet with a concave radius of curvature that matches the radius of the small spheres. The striker has a characteristic dimension of about 10-500% greater than the diameter of the small spheres.
Abstract:
A trigger type sprayer capable of easily performing air vent in a space between a second valve and a first valve, and preventing leakage of liquid in use is provided.The present invention includes a body 11 having a first flow channel 11a through which liquid can flow, a second flow channel 11d communicating with the first flow channel 11a, and a cylindrical cylinder chamber 11b communicating with the second flow channel 11d; a hollow piston 13 slidably incorporated into the cylinder chamber 11b, having a valve seat 13b and a hollow portion 13d of a second valve 14, and sliding back and forth according to operation of a trigger 12; the second valve 14 incorporated into the hollow portion 13d of the hollow piston 13 and positioned at a downstream side; and a first valve 15 incorporated into the cylinder chamber 11b and positioned at an upstream side, wherein the first valve 15 is pressed by the second valve 14 so that the first valve 15 is opened.
Abstract:
A bottle and refill pack assembly comprising an outer carton, a bag assembly and a bottle. The outer carton defines a cavity. The cavity includes a separator member which divides the cavity into a first chamber and a second chamber. The bag assembly is positioned within the first chamber. The bag assembly has a spout and a dispenser. At least one of the spout and dispenser is extendable through an opening in the outer carton to allow the dispenser to be actuatable outside of the cavity. The bottle is positioned within the second chamber. The bottle may comprise a spray bottle.
Abstract:
A trigger head for a dispensing device for at least two substances comprises pumping means suitable to compress the substances separately and simultaneously before dispensing.
Abstract:
A trigger pump dispenser has a dispensing passage, an outlet nozzle movable between an “on” position and an “off” position, and a shroud. First and second indicator tabs project from the outlet nozzle and correspond with first and second indicator windows in the shroud. When the outlet nozzle is in the “on” position, the first indicator tab resides in the first indicator window and the second indicator tab is hidden by the shroud, and when the outlet nozzle is in the “off” position, the second indicator tab resides in the second indicator window and the first indicator tab is hidden by the shroud.
Abstract:
Trigger dispensers for liquids which include a dispenser head having a sliding valve dispenser element are provided. Also provided are dispenser heads suitable for use with trigger dispensers for liquids.
Abstract:
