Abstract: A double-acting pump for ejecting a product from a container includes a piston which is axially slideable in a housing and is sealed by the housing. A hollow piston rod extends the axial bore of the piston and is slideable in a closing cap and has an actuating head, wherein, when the actuating head is actuated, the piston builds up a pressure in a pressure chamber against a restoring force of a spring. An outlet duct extends through the actuating head to an outlet opening. When subjected to the restoring force of the spring, the piston releases a passage between the pressure chamber and openings of a second housing portion. A medium which kills germs and bacteria is arranged in an expansion chamber. The dispensing stroke volume of the piston corresponds to the volume of a drop of the liquid.

Abstract: With the subject invention, a pump is formed that generally includes a reservoir formed to accommodate at least one fluid dose, and a fluid-collecting chamber in fluid communication with the reservoir. The fluid-collecting chamber includes a dose-control portion which encompasses a volume defined by two dimensions. A first piston is disposed to urge fluid from the reservoir and at least into the dose-control portion. A second piston is disposed to reversibly slide within at least the dose-control portion of the fluid-collecting chamber. A nozzle is also provided which is located such that fluid displaced by the second piston from the dose-control portion is generally urged towards the nozzle. A check valve may be placed in the fluid path between the dose-control portion and the nozzle.

Abstract: An apparatus is used to apply medicament to an eye and stores the medicament in a medicament chamber. A nozzle is coupled in fluid communication with the medicament chamber and is formed by an outer nozzle portion and an inner nozzle portion received within the outer nozzle portion. A seam is formed by the interface of the inner nozzle portion and the outer nozzle portion and is normally in a closed position to prevent the passage of medicament through the nozzle. The seam opens in response to the flow of medicament of sufficient pressure into the seam to permit the passage of medicament through the nozzle for release into the eye.

Abstract: The invention is an atomizing pump for dispensing a quantity of liquid in a fine spray. The pump mechanism is constructed entirely of plastic, including the inlet and outlet valves, the piston, pump housing, and spring. This construction allows the pump to be easily recycled. The pump can also be constructed using two biasing springs. The first spring is used only to return the pump piston; the second spring is used only to bias the outlet valve. In this manner, the person operating the pump only presses downwardly against the force of the first spring, and not the second. As a result of this biasing arrangement, less actuation force is required.

Abstract: An apparatus for applying medicament to an eye has an inner casing and an outer casing coupled to the inner casing and moveable relative thereto. An eyecup is supported on one end of the inner casing. The eyecup defines a surface shaped to conformably engage the facial tissue surrounding an eye. An ocular vial supported with the inner casing. The ocular vial holds medicament for release into an eye. An eyelid displacing member is coupled to the outer casing and slideably mounted through the inner casing. The eyelid displacing member includes a depresser tab adapted to engage the facial tissue below an eye. The depresser tab engages the facial tissue upon moving the outer casing toward the inner casing, thus displacing the lower eyelid to expose the ocular cul-de-sac. A dispensing member is supported by the outer casing. The dispensing member is adapted to actuate the ocular vial upon moving the outer casing toward the inner casing, to release medicament onto the exposed ocular cul-de-sac of the eye.
