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 polymer vial with a tubular body having a geometric shape including (i) a neck having an opening orifice, and (ii) a closed base formed by flattening and sealing a bottom edge of the tubular body. The vial will also include a snap off cap integrally formed on the neck and a liquid content contained in the tubular body. A plurality of dosage lines are printed on the tubular body, the dosage lines having a non-uniform spacing corresponding to the variable volume per unit length of the vial geometric shape. Each line corresponds to a dosage volume of the liquid content when the opening orifice is oriented in the vertically upward position.

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 wearable fluid metering device for delivering medication subcutaneously, intramuscularly or intravenously to a patient, includes a polymer actuator pump. The polymer actuator pump is flexible so it will conform to shape and yet can be used to rapidly displace a volume within a confined area. The actuator is much faster than prior art polymer actuator designs and can be actuated in multiple ways including introduction and hydration of the polymer matrix by a solution or the actuator can be actuated via pH change while it is in solution. The pH change can be made via electrical current such as that used in electro chemistry or the pH change can be made via a chemical change introduced to the actuator hydrating solution.

A liquid dosing device for a container includes a dosing chamber having a front end and a back end. An outlet passage is located at the front end. A plunger is located in the dosing chamber, divides it in a front and a back space, and is moveable between a forward position in which the plunger closes off the outlet passage, and a backward position, in which the front space has a maximal volume. An inlet passage provides fluid communication between the front space and the container. A timer passage provides fluid communication between the container and the back space. A release passage, being greater than the timer passage, provides fluid communication between the back space and the container. A valve assembly at the release passage includes a valve seat located at the back end of the dosing chamber.

A fluid device with a fluid chamber, the fluid device including a fluid chamber which is designed for receiving a fluid and which is commonly delimited by a device housing and a bending-elastic membrane element. The membrane element is fixed with a peripheral edge region to the device housing, wherein a membrane working section of the membrane element which is framed by the peripheral edge region can be deflected by a piezoactuator whilst carrying out a stroke movement, in order to change the volume of the fluid chamber. The membrane element is a functional constituent of the piezoactuator by way of it directly forming an electrically conductive electrode of the electrode arrangement of the piezoactuator.

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.

Disclosed is a pump head with a specially configured elastic valve which enables secure closure of the pump head. It is ensured by the valve that complete emptying and, at the same time, secure closing of the pump head is ensured so that no residues of fluid to be metered remain in the storage state of the pump head. In addition, the present invention relates to a metering device which can be configured for example as squeeze bottle, as non-airless system or as airless system, the metering device comprising a pump head according to the invention.

In one embodiment, a delivery device for administering liquid includes a bottle body having a bottle neck, a bottle cap configured to attach to the bottle neck, a nozzle associated with the bottle cap, and a valve assembly associated within the nozzle, the valve assembly comprising a liquid metering valve configured to ensure a precise, predetermined volume of liquid exits the nozzle each time a user actuates the delivery device.

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.
