    Abstract: The dispenser outlet (13) is microbiologically sealingly closeable by a valve stopple (25) which closes counter flow direction (11). Outlet 13 is manually reversely opened prior to the pump stroke against a spring (34). The medium reaches outlet (13) via throttles (22, 21, 49). Thus the medium creeps practically non-pressurized to an adhering face (51) of a droplet former (50). There the medium accumulates to a droplet suspending in the upside-down position. The medium contained in the dispenser (1) is effectively protected from germ contamination and the droplet may be simply administered to an eye or the like.

    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 is supported within 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 actuated 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.

    Abstract: A thrust piston pump for an active substance dispenser has two equiaxial, position-rigid, interconnected pistons running in the same direction, namely a pump piston passing in and out of an otherwise closed pump chamber and a larger presuction pistion located downstream thereof, in whose associated pressure chamber is located the pump chamber end opened by the passing out of the pump piston. This leads to a very accurate dosing of the discharged active substance quantity, accompanied by a simple construction and high operational reliability.

    Abstract: A liquid dispensing pump includes a one-piece piston capable of not only effecting a pumping operation but also an outlet valve opening and closing function upon limited relative axial movement. In one embodiment, the piston reciprocates and forms a valve seat for a container vent opening extending through a closure cap provided on the pump body, and in another embodiment, the pump cylinder reciprocates and forms a valve seat for opening and closing the container vent opening. The pump chamber defined by the cylinder has a valved inlet which may be formed by a sleeve depending from the piston and an upstanding conduit in the cylinder or may be formed by a ball check valve in the cylinder.

    Abstract: A vented pump and pre-loaded spring for dispensing liquid at a controlled rate from a container upon depression of a plunger or stem. A pump body extends within the container and houses the stem and piston. The lower end of the stem functions as an inlet valve. The piston is slidable on the stem between upper and lower stop limits and seals the outlet passage in the stem when the plunger is in a raised position. An initial downward movement of the plunger closes the inlet valve and then, after a slight build up of pressure within the pump chamber, moves the outlet passage downwardly of the piston into communication with the pump chamber below the piston. Continued downward motion of the stem moves the piston downwardly and expels the liquid through the outlet passage while maintaining a constant seal at the inlet valve. A sealing disc cooperates with the plunger or stem to prevent air from entering the container when the stem is in the raised position and to allow air to enter the container through a fluid vent passage formed between cooperating surfaces of the container, stem, disc and pump body when the stem is moved toward the down position. A variety of types of fluid vent passages are provided, such as, a plurality of rounded knurls on the outside surface of the pump body to assure an open fluid vent passage after the pump body is crimped to the container and provision is also made for use of a flange adaptor, with or without knurls, for non-crimping modes of constructing the pump assembly.
