Disclosed is the invention of a pump dispenser wherein a deformation prevention locking part induces a chaplet to move in the axial direction in a housing at the time of rotation of a head part, thereby allowing or restricting an operation of pressing a head part while preventing the deforming of an elastic member. The disclosed pump dispenser comprises: a cap part fastened to a container; a housing which is provided at the cap part and in which a content stored in the container remains in a dischargeable state; a shaft received in the housing so as to be movable in the axial direction, the shaft including a head part for discharging the content remaining in the housing to the outside through a pressing operation by an external force; a chaplet provided in the housing such that the shaft is inserted so as to be able to extend therethrough, the chaplet allowing or blocking the movement of the shaft on the basis of the angle of rotation of the head part; an elastic member provided on the circumference surface of the shaft and elastically supporting the chaplet and the head part; and a deformation prevention locking part for inducing the chaplet to move in the axial direction in the housing at the time of rotation of the head part, thereby allowing or restricting an operation of pressing the head part while preventing the deformation of the elastic member.

The present invention is an improved nozzle for spraying viscous substances which includes the following key elements: (1) the nozzle includes a round hole at the nozzle middle-center location; and (2) the center round hole is surrounded by five circumferential modified trapezoid shaped hole openings, with each of the modified trapezoid shaped hole openings having a pair of divergent sidewalls with an arcuate top wall and a smaller acuate bottom wall and set at a distance separated from each other at seventy-two degrees in a circle around the center opening. The distance from the center of each circumferential opening to the middle center opening is also the same. The present invention will enable the spraying of heavy viscous substances and gels.

A micro pump vessel has an outer vessel on one side of which a button is formed and an outer vessel lid which is hinge-coupled to one side of the outer vessel to be opened and closed. In the vessel, a first and a second pistons are installed on an upper surface of cosmetic contents, and thus, when the cosmetic contents are pumped and used by the operation of a micro pump, the first and the second pistons lower to exhaust all the cosmetic contents so as not to discard the remaining cosmetic contents.

The invention relates generally to a device for actuating a pump mechanism capable of expelling a flowable composition from a container reservoir. In particular, the actuation capability is derived from a living hinge which is constituted by an elastomeric region of the actuator. More specifically, the invention relates to a molded actuator having a button portion for pressing, a collar portion for securing to a container, and a living hinge portion formed of a material that is sufficiently pliable to allow movement of the button portion relative to the collar in a resilient manner.

[Object] To provide a trigger-type pump dispenser A which is configured such that a trigger section 13 is depressed by a thumb with a handle gripped, which is good in grippability, which allows efficient transmission of finger pressure to the trigger section 13 during spraying, and which is excellent in operation. [Solution] The present invention is directed to a trigger-type pump dispenser including: a cylinder section; a handle section 12; a trigger section 13 located above the handle section 12; and a nozzle section 4 from which liquid is sprayed out of the cylinder section by depressing the trigger section 13 with the handle section 12 gripped, wherein the handle section 12 has a finger contact portion S located posterior to a point of force of the trigger section 13.

In a pump dispenser having a form where a user grasps a grip to push down a finger putting portion with the user's thumb, the present invention provides a push-type pump dispenser that has a good transmission property of a finger force and is excellent in operability.

The present invention is a push-type pump dispenser A that injects liquid within a cylinder portion 11 from a nozzle portion 32 by pushing down the finger putting portion 31 located above a grip portion 12 in a state where the grip portion 12 has been grasped by a user, wherein a finger abutting portion S of the grip portion 12 is located behind a power point P1 of the finger putting portion 31.

A metering dispenser for simultaneously or selectively discharging two media, including an outlet opening, a first reservoir for a first medium, a first metering-conveyor device for conveying the first medium from the first reservoir, a second reservoir for a second medium, a second metering-conveyor device for conveying the second medium from the second reservoir, a mixing chamber arranged upstream of the outlet opening and in which the first medium, conveyed by the first metering-conveyor device, and/or second medium, conveyed by the second metering-conveyor device, is stored temporarily, and an output-conveyor device for conveying the medium or media from the mixing chamber to the outlet opening. The first metering-conveyor device has the form of a metering-pump device with a variable-volume metering chamber, an inlet fluidically connected to the first reservoir and having an inlet valve, and an outlet fluidically connected to the mixing chamber and having an outlet valve.

A pre-push miniaturized atomizing device has blank cap fixed to the outer diameter of pump nozzle underneath L-shaped water inlet of body. The blank cap and elastic body are fastened to the hole on the side of a large ring of body, the elastic body water outlet hole has a fastened and fixed valve needle, the thru-hole is connected to piston cavity in body, the outer diameter of the elastic body water outlet hole is set against the inner wall underneath the piston cavity at the L-shaped water inlet hole of the body to form a spray hole clearance. As the valve needle floats up and down in the water outlet hole, the clearance passage between the valve needle and elastic body opens or closes, while the spray hole clearance between the elastic body and the piston cavity closes or opens as corresponding to the deformation of the elastic body.

A hand-held integral airbrush comprising a shell provided with a grab handle, wherein an upper accommodating cavity and a lower accommodating cavity are formed in the shell, wherein an airbrush assembly is arranged in the upper accommodating cavity of the shell, and wherein an air pump assembly is arranged in the lower accommodating cavity of the shell and is used for pumping compressed air into the airbrush assembly, wherein the hand-held integral airbrush further comprising a switch part, an operating button which comprises a first control part and a second control part, wherein an air pump and an airbrush are integrated in a the ergonomically designed grab handle, and wherein the air pump and the airbrush are controlled by the trigger-type operating button.

In exemplary embodiments of the present invention, various novel dispensing devices can be provided. Such devices can involve a range of sprayer heads and sprayer/foamer systems incorporating such heads. Novel sprayer/foamer heads can include buffers of various types. By using a buffer, a user need not continually be pumping the device in order for the device to be spraying or foaming. In exemplary embodiments of the present invention, such a buffer can be spring loaded, spring loaded combination, elastomeric or gas. In exemplary embodiments of the present invention, the buffer can be in line or adjacent to a piston chamber. If adjacent, it can be connected to the piston chamber with a one way valve, to provide for spray after a downstroke of the piston has been completed, or without, to allow spraying to cease once a user releases the trigger or other actuator. In exemplary embodiments of the present invention, such novel sprayers and foamers can be mounted upside down, in various “Flairomop” devices, used to clean floors or the like. When using a buffer, a piston chamber can be designed to deliver greater amount of liquid per unit time than can be possibly dispensed through the nozzle or nozzles. The fraction of liquid that cannot be sent through the nozzle(s), due to their inherent restriction, can thus be sent to the buffer for dispensing after the piston downstroke has been completed. A volume of the piston chamber, a volume of the buffer, a pressure response of the buffer, the throughput of the nozzle, and the minimum opening pressure of the outlet valve can be arranged to restrict the outlet pressures of liquid droplets exiting the nozzle within a defined range.
