The present invention relates to a pump head that enables a metered dispensing of fluids. The present invention also relates to a metering apparatus that can, for example, be configured as a squeeze bottle, wherein the metering apparatus comprises a pump head in accordance with the invention.

The present invention relates to a dispensing head (1) for a dispensing device, and to a dispensing device (100) for the metered dispensing of liquid preparations, which dispensing device is provided with the dispensing head. The dispensing head comprises a special valve (6), which comprises at least one sealing lip (7a, 7b), by means of which a passage channel (3) for dispensing the liquid preparation, which passage channel is formed in the dispensing head, can be closed. The present invention is characterized by the simplicity of the dispensing head (1) and the economic advantages in the manufacturing which are linked to this simplicity.

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.

A dispensing system including a cap configured to secure the dispensing system to a bottle filled with a formula, wherein the cap is configured to retain a metered dose of the formula, a shaft in fluid communication with the cap, a bladder inside the cap, wherein the bladder comprises one or more openings, and wherein the bladder is configured to lift to cover the shaft, a distributor nozzle in fluid communication with the shaft, and an outer nozzle covering the distributor nozzle and configured to dispense the formula.

A liquid direct injection assembly includes a direct injection supply kit to mix liquid components into a mixture and deliver the mixture to a treatment device. The supply kit includes one or more liquid component containers that each include an elongated flexible bladder and a discharge nozzle to discharge a corresponding liquid component from the bladder. The supply kit also includes one or more metering bodies each defining a metering orifice to control a flow rate of the corresponding liquid component from the bladder. The liquid direct injection assembly also includes a container tray configured to removably support a liquid component container.

A selectable volume precision liquid dispenser apparatus and method of use. The dispenser apparatus includes a graduated, segmented elastic body with an interior space having different regions corresponding to different volumes where different liquid containing chambers are separated by one-way valves. Pressure applied by a user to one of the different chambers causes the dispensing of a precise amount of liquid through an inner conducting tube having openings to receive liquid in each of the different regions, and an outlet for dispensed the liquid. Release of the pressure allows the elastic body to return towards its original (resting) shape and draw liquid from a reservoir into the previously dispensed region in preparation for the next dispensing operation.

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.

A flexible container, bottle or bag with a one-way valve adjacent to a pressure close tight or bubble valve, operating as a dispensing valve, in order provides a metered dosing element. The dispensing valve for flexible packaging, using an extruded profile as a valve which requires internal pressure to overcome the seal effect or bias of the profile alows for metering of the contents of a flexible package.

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.
