International Classification:

G01F 1136

US Classification:

222321

Abstract:

A manually-operated pump dispenser for dispensing liquids from a container. The dispenser includes a one-piece housing coupled to the container, a dip tube extending from the housing into the container, a one-piece pump member which is slidably supported in the housing and which has a trigger extending therefrom and a nozzle member at the end, a pair of one-way valves supported by the housing and pump member, a one-piece, plastic tubular member which engages the housing and pump member and forms a part of at least one of the one-way valves in the dispenser, and a spring engaging a portion of the pump member and the tubular member for biasing the pump member away from the housing. In a first embodiment, the tubular member forms a part of each of the one-way valves, and in a second embodiment, it forms a part of the inboard one-way valve. In this second embodiment, the outboard valve is formed by the nozzle member and the pump member, both being formed of plastic. In another embodiment, the tubular member is eliminated, the inboard valve is formed by the housing and the pump member, and the outboard valve is formed by the pump member and the nozzle member.

Abstract:

A manually-operated pump dispenser for dispensing liquids from a container. The dispenser includes a one-piece housing coupled to the container, a dip tube extending from the housing into the container, a one-piece pump member which is slidably supported in the housing and which has a trigger extending therefrom and a nozzle member at the end, a pair of one-way valves supported by the housing and pump member, and a resilient, annular biasing member which engages the housing and pump member, has a stretchable portion providing a restoring force to the pump member and forms a part of at least one of the one-way valves in the dispenser. In a first embodiment, the biasing member forms a part of each of the one-way valves, and in a second embodiment, it forms a part of the inboard one-way valve. In this second embodiment, the outboard valve is formed by the nozzle member and the pump member.

International Classification:

B05B 9043

US Classification:

239333

Abstract:

A spring (304) biases a movable housing part (12, 16) away from a fixed housing part (10, 306, 156). The fixed housing part (10, 306, 156) is composed only a main housing (10), a draw tube (306) and an inlet valve housing (156). The inlet valve housing (156) is inserted into the main housing (10). The movable housing part (12, 16) is composed of a forward housing (12), which includes a trigger (14), and a nozzle (16). The main housing (10), the inlet valve housing (156) and the forward housing (12) together form a variable volume pump chamber (318). The inlet valve (184, 268) includes , a valve plug (184) which is initially connected to a sidewall portion (168) of the inlet valve housing (156) by a frangible section (196). During assembly, an axial push is imposed on the valve plug (184), to sever the frangible section (196), and then move the valve plug (184) rearwardly past stop lugs (198, 200), into a position axially between the stop lugs (198, 200) and an inlet valve seat (268). The nozzle (16) is rotatable between an "open" position in which two sections (64, 97) of an outlet passageway are in alignment, to permit liquid flow from the pump chamber (318) to an outlet opening (46) and a "closed" position in which the two passageway sections (64, 97) are out of alignment, and flow out from the pump chamber (318) is blocked.

International Classification:

B67D 540

US Classification:

222321

Abstract:

A manually-operated pump dispenser (10) for dispensing liquids from a container (28). The dispenser comprises a housing (20), a closure (22) for coupling the housing to a container (28), a pump member (14) having a trigger (84) rigidly extending therefrom and being slidably received in the housing, a coiled spring (16) for biasing the pump member away from the housing, and an adjustable nozzle (12) coupled to the end of the pump member. The pump member and the housing include cooperating slots (86, 89, 90) and flanges (120, 121) and cooperating square portions (71, 115) for resisting the tendency of the pump member to distort about an axis transverse to the housing upon engagement of the trigger (84), thereby maintaining the pump member and the housing in longitudinal alignment. The dispenser includes an inboard valve member (18) received in the housing and an outboard valve (26) formed by the adjustable nozzle (12) and the pump member (14), without the need of an addditional part. The adjustable nozzle (12), pump member (14), inboard valve member (18), housing (20) and closure (22) are each integrally molded as one-piece.

International Classification:

US Classification:

9310AA

Abstract:

An adjustable heel assembly for a water ski binder in which the component parts of the heel assembly are united in functional relationship relative to one another without the aid of additional mechanical fasteners. An elastomeric heel member is cooperatively interlocked to a base member which is slidably and adjustably disposed between a pair of side rails. The base member is adjustably connected to the side rails by a selectively operated lock mechanism carried by the base member. The heel assembly and the side rails are spaced from the ski so as to allow fluid to flow between the components of the heel assembly and the surface of the ski and thereby prevent the buildup of debris therein.

International Classification:

B67D 542

US Classification:

222135

Abstract:

A dispenser for simultaneously dispensing and mixing a pair of fluid products such as chemically reactive resins, from a pair of axial adjacent front and rear chambers. A piston is mounted within each of the chambers and is moveable with respect to the hollow interior of the respective chamber for dispensing the fluid product therefrom. Telescopic movement of the rear chamber within the front chamber moves the pistons synchronously through the chambers to provide for controlled discharge of the products through a front discharge nozzle. A fixed hollow delivery tube extends through the interior of the front chamber and telescopically receives therein a post which is mounted on a rear wall of the rear chamber. The rear chamber has a relatively tight sliding fit within the front chamber so that a partial vacuum is formed within an annular space which forms between the two pistons as they move apart upon discharge of the two products to produce a "suck back" effect on product remaining in the discharge nozzle.

Abstract:

A trigger sprayer for generating a spray of liquid from a container comprising five parts including a housing having a tubular piston with an open ended liquid flow passageway therein; a tubular actuator member slidably received over the piston, having a trigger rigidly extending therefrom and defining a chamber therein with a spray orifice at one end; a rod disposed in the actuator member and including a frustoconical skirt forming a valve in the chamber across the spray orifice; an inlet valve carried by the tubular piston and including an extended valve portion slidably seated on the rod, and a biasing spring disposed between the valves. The inlet valve may include a shipping seal member formed integrally therewith and disposed on the inlet passage to seal it until the sprayer is ready for use whereupon the rod will displace or break the seal upon actuation of the sprayer.
