A device for precise dispensing of liquids utilizing pressure-operated valves to control fluid travel. Use of a flexible bulb within a fluid vessel provides manual actuation of the valves through application of pressure to the exterior of the fluid vessel.

A system for a soap container including a container assembly and a drawer assembly is disclosed. The container assembly includes a container. The container houses and maintains a sponge member and a soap solution readily available to a user for cleaning of a desired surface. The container includes a reservoir at a top portion. The reservoir has an open top face and is refilled through the top face once the soap solution is depleted. The reservoir is selectively sealed with a tray. A nozzle is attached to the reservoir to dispense the soap solution within. The drawer is removably secured to a slot at a lower portion of the container. The sponge member is removably secured within the drawer, such that when the drawer is opened, the sponge member is underneath of the nozzle, which is actuated to dispense the soap solution onto the sponge member.

What is disclosed in the present invention is to provide a quantitative transfer pipette structure, wherein an anti-backflow compartment is configured in the first bulb. The dimensions and locations of the first bulb, the second bulb and the third bulb are specifically configured to aspirate and transfer a specific volume of the liquid to a container, mix the liquid with the substance in the container by pressing and releasing the specific bulbs, so as to achieve the effects of precise quantification and sufficient mixing.

A device for providing a droplet of a liquid stored in an interior of a vial is disclosed that includes a support body and a resilient dome portion mounted to the support body to form a chamber having air, with the dome portion being configured to create an air flow when activated by compression. The support body includes a vial seat, a nozzle, and air flow and transfer conduits. The support body is arranged, when the vial is received by the vial seat, such that the air flow conduit establishes an air connection between the vial interior and the chamber, the transfer conduit establishes a fluid connection between the vial and the nozzle, and, upon activation of the dome portion, the air flow delivers air into the vial that causes liquid to be transferred from the vial to the nozzle through the transfer conduit.

A method and device for conveying tracking and communicating information concerning a dispensed fluid, the device including a measured dispensing device attached to a flexible collapsible container, the device including a sensor for measuring a physical property relating to the dispensing operation, and a communication device configured to communicate information determined by the sensor to a remote device.

A device for transferring liquids and liquid samples in certain quantities includes a housing, a pressing unit, a liquid extraction assembly, and a connecting member. The pressing unit includes an extrusion portion. The housing includes a first sidewall and a second top wall. The first sidewall and the second top wall cooperatively define a receiving cavity. The pressing unit is received in the receiving cavity. The liquid extraction assembly includes a liquid extraction pipe. The liquid extraction assembly is detachably connected to the housing through the connecting member. The pressing unit can move back and forth along the central axis of the receiving cavity, so as to move the extrusion portion back and forth relative to the liquid extraction pipe. The liquid extraction pipe is deformed by the extrusion portion to take up or release liquid in precise quantities.

A fluid dispensing device having a flexible fluid pouch and a dispensing assembly, the dispensing assembly having a top piece and a bottom piece, the top piece having a flexible actuator including a flexible dome and a flexible flange extension, the bottom piece having a bottom portion of a pump chamber, a pump chamber inlet, a chamber inlet valve, and a bottom portion of an outlet valve, the top piece and the bottom piece mated together to form a pump chamber and an outlet valve, the device configured to allow bidirectional fluid flow through either or both inlet and outlet valves, and to dispense a volume of fluid that is less than the volume of the pump chamber. The flexible pouch may have a single opening or two openings. In the case of a single opening, the entire dispensing assembly is in the interior of the pouch. In the case of two openings, only the flexible dome extends to the exterior of the pouch. The outlet valve is configured so that the more pressure that is applied to the flexible fluid pouch, the more tightly the outlet valve seals.
