摘要:
A device mountable on a material container for dispensing fluid or pasty material therefrom is disclosed. The device comprises a first pump (10) for selectively dispensing the material from the container through an outlet (31), said first pump being mountable on the container by means of an attachment member (11), and a manual actuation member (30) movable between an inoperative position and an actuated position. The device further comprises a second pump (20) for dispensing compressed air at the same time as the material is dispensed. The second pump comprises two elements (21, 22), i.e. a plunger (21) and a pump cylinder (22) slidably housing the plunger (21), and is designed to feed a flow of compressed air to the outlet (31) in order to spray the material. One of said two elements (21, 22) of said second pump (20) is secured to said attachment member (11) of the first pump (10), whereas the other of said two elements (21, 22) is secured to the actuation member (30).

The present invention relates to liquid dispensers, more specifically to a multi-port dispensing system that allows the user to either receive a spray of liquid for cooling or a stream of water for drinking. The preferred embodiment of the present invention consists of an ejector (or spray head) that attaches to a body. The body in turn attaches to a container. Once fully assembled, the user may drink liquid from the container by sucking on the straw protruding from the body. Simultaneously or sequentially with drinking from the straw, the user may receive a refreshing spray from the ejector.

An atomizer device for liquids pressurized by a manually operated pump, without pressurizers, comprises a nozzle with an obturator to which a plunger member is connected, The liquid pressurized by the pump acts on this plunger and moves the obturator against a spring, opening the nozzle. Interceptors, which allow the liquid to pass and consequently to be sprayed outwards only when the obturator has moved by a given amount, moving away from the nozzle and forming a predetermined chamber about the nozzle, are provided in the passage for the liquid to the nozzle. The uniformity of the fan of the jet of liquid within the course of each operating cycle of the pump and its constancy in the different cycles is thus ensured.

A low cost trigger sprayer has a housing with a first liquid passage containing a spinner assembly. An elastomeric pump element is positioned generally horizontally such that pulling the trigger retracts the element and releasing the trigger allows the element to extend. The sprayer includes a low cost spinner assembly and low cost valving to control the flow of liquid within the sprayer. In one aspect of the invention, the housing has front and rear sections with the rear section having a saddle portion and being hinged to the front section for pivotal movement from an open position for molding the housing to a closed position for operating the sprayer. In another aspect of the invention, the container has a rear portion which extends upwardly past the neck and defining a saddle recess, with the housing connected to the neck of the container and positioned forwardly of the upwardly extending container portion. The sprayer may include an elastomeric spring for biasing the pump element in the extended position.

A hygienic spray bottle dispenses liquid through a discharge tube. The spray bottle includes an electrically powered pump for pressurizing the liquid; a discharge tube having a nozzle; a valve for dispensing the pressurized liquid; and a pickup tube extending to the bottom of the bottle. A rechargeable battery powers the pump. The discharge tube is configured to cooperate with a toilet bowl wall to allow the spray bottle to function as a portable bidet. The discharge tube has a sliding sleeve for selectively covering and uncovering liquid spray holes to vary the spray pattern or location. Alternatively, the discharge tube includes a flexible section to vary the orientation of the nozzle for douching. The hygienic spray bottle is capable of being used in the absence of an external plumbing system.

A fluid-dispensing device which selectively draws fluid out from at least two containers or fluid chambers, mixes the fluids in a desired concentration or ratio and expels the mixture of fluids out a nozzle. The dispensing device may be equipped with a mechanism for variably controlling the ratio of the fluids being mixed. The containers may be bottles connectable to the fluid-dispensing device and selectively detachable for refilling with fluid or exchanging one of the containers with another container having an alternate fluid. The bottles include mating elements to permit interconnection of the bottles as well as venting and spill prevention mechanisms.

A portable spray apparatus including a bottle reservoir for holding fluid, a manually actuatable pump secured to the bottle reservoir, and an elongated fluid conveying tube having one end connected to the output of the pump and being in the form of a flexible loop section and an elongated output section, wherein the loop section is between the pump output and the output section. The output section of the tube is supported by an arm assembly that is pivotally supported by a support rack which allows the support arm to be positioned at different angular positions.

A hand-operated pump for dispensing a fluid from a container includes a body containing a pumping chamber having an inlet and an outlet. A piston is reciprocably mounted in the pumping chamber, the piston having a convexly contoured outer end surface. A trigger pivotally mounted to the body has a plurality of triangular supports co-joined to form a tapered socket receiving the outer end surface of the piston. A channel-defining insert is received in the outlet, the insert having a centrally situated, forwardly facing, fixed protuberance. An elastic, cup-shaped member secured at its periphery to the body has a central aperture situated in contact with and closed by the fixed protuberance. The central aperture of the cup-shaped member is a cavity in the center of the interior surface of the member extending only partway through the member, at least two depressions on the exterior surface of the member spaced from each other yet each intersecting the cavity, and a swirl chamber situated between and connected to the depressions.
