A pump 1 for dispensing a cosmetic product, having a pump body 10 and a diaphragm 20. The pump body 10 and the diaphragm 20 are rigidly interconnected and together define an interior space 19 in the pump 1. The pump 1 is equipped with an intake valve 222, which is designed to regulate the intake of the cosmetic product into said interior space 19. The pump 115 is equipped with an outlet valve 201, which is designed to regulate the expulsion of the cosmetic product from said interior space 19. The dispensing pump 1 is designed such that the diaphragm 20 being pushed down causes the intake valve 222 to close and the outlet valve 201 to open, and such that the diaphragm 20 being released causes the outlet valve 201 to close and the intake valve 222 to open.

A device for dispensing a fluid includes a pocket whose interior volume is delimited by a deformable wall; a pressing surface; a dispensing part including a dispensing cavity, an outlet; a dispensing orifice connecting the pocket to the dispensing cavity, and a dispensing valve located in the dispensing cavity.

A dispenser that includes a nozzle that is configured to dispense a fluid. The dispenser also includes a pump in fluid communication with the nozzle and a pulsation dampener in fluid communication with the nozzle. The pulsation dampener has a spring biased movable piston. The dispenser is configured to, when the pump is activated, emit a substantially constant stream of the fluid from the nozzle for at least one second.

The disclosure relates to systems and methods for metering a dose volume of fluid that may be used to treat microelectronic substrates. The system enables precision dispensing of relatively small amounts of a liquid chemical into a chemical bath or processing chamber for microelectronic substrates. The dispensing device may include a fluid conduit with a plurality of actuation devices that may limit fluid communication between the actuation devices and store a portion of the fluid in expandable membrane. The actuation devices may push or pull the fluid within the fluid conduit when the expandable membrane expands or contracts. The configuration and operation of the actuation devices may enable the collection, isolation, and dispensing of the dose volume.

The invention relates to a device for dispensing a fluid including: a tank arranged so as to contain the fluid; a dispensing pipe arranged so as to guide the fluid in a dispensing direction; a dispensing opening connecting the tank to the dispensing pipe; a dispensing valve which, in an open state, allows fluid to pass from the inside of the tank to the dispensing pipe via the dispensing opening and, in a closed state, does not allow fluid to pass from the inside of the tank to the dispensing pipe; and a return means arranged so as to exert a force on the dispensing valve. Said force moves the dispensing valve from the open state thereof to the closed state thereof. The return means includes a pouch forming a cavity. Said pouch is located in the dispensing pipe. The shape of the pouch is changed via compression when the dispensing valve is in the open state.

An applicator head for a dispenser for cosmetic or pharmaceutical liquids and foodstuffs, having a pump device with a pump chamber, an inlet valve arranged between a suction intake and the pump chamber, an outlet valve arranged between the pump chamber and an applicator opening, and an actuating arrangement with the aid of which an inner volume of the pump chamber is changed. At least two of the three components from the group including the outlet valve, the inlet valve, and the actuating arrangement each include at least one elastic section formed from an elastically deformable material, the elastic sections of the at least two components are integral parts of an interlinked elastic component section of a uniform elastic material having a connection area between the at least two components, and the connection area, in the installed state of the application head, is in an elastically deformed state.

The present invention provides a cosmetic container for powder having a pumping structure, the cosmetic container including: an accommodation portion (100) configured to accommodate a powder material; a lower support portion (200) disposed over the accommodation portion (100), and configured to allow air to be introduced such that the powder material accommodated in the accommodation portion (100) is discharged together with the introduced air; an air pumping portion (300) disposed over the lower support portion (200), and configured to pump air so that the air is introduced into the lower support portion (200); an intermediate support portion (400) disposed over the air pumping portion (300), and configured to discharge a powder material together with air and to collect the remaining powder material; and a powder discharge portion (500) spaced apart upward from the intermediate support portion (400), and configured to allow the discharged powder material to be collected.

An eye cream packaging container that includes an outer bottle wherein a material accommodating assembly is arranged in the outer bottle, and a material dispensing assembly is connected to a bottleneck of the outer bottle; the material accommodating assembly has an inner container and a flexible material bag arranged, and the inner container has multiple through openings; the material dispensing assembly has a middle seat, a middle seat inner cover and a flexible manual press cap; the middle seat inner cover is arranged in the middle seat, the middle seat inner cover is connected to outside of the bottleneck, and a one-way valve plug is arranged in the middle seat inner cover; and the flexible manual press cap is arranged at the top of the middle seat inner cover, and the middle of the flexible manual press cap is provided with a pressing region and a discharging region.

A pumping device, comprising an actuator and a closure, the actuator being connected to the actuator. The pumping device further comprises a collapsible bladder, the collapsible bladder being formed by connecting a plurality of segments, and an included angle being formed between two adjacent segments, wherein at least two adjacent segments are connected to each other by means of a weakened portion.

A droplet dispenser for dispensing cosmetic or pharmaceutical liquids in the form of individual droplets, having a medium reservoir with a first and second medium chambers, which are isolated from one another for separately storing two media. The medium chambers are connectable to produce a combined liquid. The droplet dispenser has a discharging opening and, downstream of the discharging opening, a droplet forming contour in order to create droplets which detach from the droplet forming contour as soon as the droplets have reached a defined volume. The droplet dispenser has a pump device between the medium reservoir and the discharging opening, wherein the pump device has a variable-volume pump chamber for delivering combined liquid. The pump device has an inlet valve on the entry side and an outlet valve on the exit side.
