  • Patent number: 6484715
    Abstract: A dispenser (1) has two remote pressure handles (29, 35) and lateral gripping recesses (58) for mutually displacing two units (2, 3) axially and rotationally. A tear-off web (52) prevents the two units (2, 3) from being actuated accidentally. A discharge stud (34) protrudes beyond the handles (29, 35, 58). The dispenser (1) is so small that it may be fully enveloped and covered by one user's hand. Nevertheless reliable actuation for nasal application is assured.

  • Patent number: 6478196
    Abstract: Radial actuation of a handle (15) axially retracts the dispensers shaft (6) inclusive an exit head (9) relative to a base body (5) and a reservoir (7). The shaft (6) is prevented from rotating. The medium thus flows from a pressure chamber (26) via an outlet valve (32) through the entire shaft (6) to a medium exit (20) while being swirled. For facilitated handling the base body (5) and the reservoir (7) form a rod-shaped grip with the handle (15) on one side and a finger scallop (72) on the other.

  • Patent number: 6454185
    Abstract: The problem of the invention is to provide an easily manipulatable and long term-usable discharge apparatus. A discharge apparatus for media, particularly for spraying a fluid preferably containing a pharmaceutical substance according to the invention has a casing. On said casing is located an actuator, which is movable relative to the casing by a path corresponding to an actuating stroke path. The discharge apparatus has a control unit, which determines at least the time which has elapsed since the last actuation of the actuator. An actuating stop, operable by the control unit in a controlled manner, in its blocking position blocks the performance of an actuating stroke and allows an actuating stroke to take place in its release position. Such an actuating stop has a blocking member, which can be brought by means of an electromagnet from the release position. into the blocking position and/or from the blocking position into the release position.

  • Patent number: 6427684
    Abstract: The problem of the invention is to so further develop a discharge apparatus according to the preamble that it is possible during each individual actuating stroke to reliably discharge a predetermined volume of medium. A discharge apparatus for media according to the invention has a casing, on which is located an actuator. During each actuator actuation an actuating stroke takes place and consequently a given volume of the medium stored in the casing is discharged. According to the invention the gravity dependently operating blocking means are constructed in such a way that they can block the performance of an actuating stroke as a function of the spatial position of the discharge apparatus.

  • Patent number: 6427876
    Abstract: A dispenser includes a nozzle body (3) which is mounted to an actuating head (2) parallel to a center axis (10) of the dispenser. Within the head (2) the despenser includes an air pump (33) which ports into the nozzle body (3) additionally to ducts for the liquid medium. Head (2) may be preassembled with the associated pump piston (41) to provide a unit which is axially mounted on a thrust piston pump (32) for the liquid medium. Thereby piston (41) snaps into a flanged rim (42) of a crimp ring (39) which thus positively connects piston (41) to the pump base.

  • Patent number: 6367473
    Abstract: For discharging a medium, such as a powder, a film/foil seal (16) of a reservoir chamber (24) is pierced by a tool (40) in a first axial movement, after which the medium is suctioned via an orifice (9) in feeding a delivery flow via passageways (55) from the chamber (24). On completion of a return stroke and twisting the tool (40) relative to the reservoir body (6) a further chamber (24) may be emptied in the same way, thus enabling e.g. a pharmaceutical active substance to be administered in two individual doses as expedient for nasal treatment.

  • Patent number: 6364166
    Abstract: For the discharge, particularly atomization of media, particularly liquid medicaments, a dispenser (11) is provided, which discharges a charge of the medicament in only one or optionally a few strokes. Actuation takes place between three fingers of the user, the thumb pressing an actuating pusher (80) in the actuating and discharge direction. In order to prevent an unintentional actuation and simultaneously protect the discharge opening (44) against dirtying and contamination, a protective cap (90) is provided, which covers the entire discharge section (13) and the holding surfaces (14) for actuation. It also has web-like projections (93) extending up to the actuating pusher (80) and securing the latter, which prevents an actuation when the protective cap is fitted. However, actuation is possible after removing the protective cap, which is secured by a snap connection.

  • Patent number: 6321942
    Abstract: A disposable atomizer for discharging successive partial discharge amounts as a spray has a base body (12), a projecting nose adapter (13) with a nozzle (14), actuating shoulders (35) where two fingers can rest, and an actuating part, containing an actuating sleeve (25) and a medium store (20), which can be pressed into the base body (12). A hollow needle (17) can penetrate the closure piston-stopper (21) of said medium store (20). A ring (28) is mounted on the actuating sleeve (25) by spokes (29) and predetermined breaking points (30), the ring (28) separating in response to typical actuating pressure when the actuator is used the first time. The spokes (29) strike a stop which thus limits the first partial discharge stroke. By rotating the actuating sleeve (25), the actuating part is moved into a starting position for a second partial discharge stroke, and when intermediate webs in the form of material bridges are broken out, the second partial discharge stroke can be executed.

  • Patent number: 6308867
    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.

  • Patent number: 6257454
    Abstract: The outlet (12) of a dispenser reservoir (8) is sealingly closed by a transverse catch member (21) which also positively prevents the dispenser (1) from being actuated. Pulling out the catch member (21) opens the reservoir (8) and releases the discharge actuator (37). Thus the piston (14) opposing the reservoir outlet (12) can enter. The materials of the reservoir (8) and reservoir seal (30) are paired in glass, tetrafluoroethylene or the like. Thus even sensitive media may be stored in the dispenser (1) over lengthy periods without risking any change in the substances.

  • Patent number: 6257461
    Abstract: Two components (2, 3) of a medium dispenser are initially injection molded from a plastics material in one part so as to form a stamp die (6) and a punching ram (7) while being interconnected only by ultra-fine joints (4, 30). The component (3) forming the ram (7) is then linearly displaced in direction (12) into the other component (2) by pressure loading. Thus the joint (4, 30) is severed analogous to shear cutting. This results in very simple production with precisely the same material quality of both components (2, 3).

  • Patent number: 6250509
    Abstract: The dispenser orifice (13) may be closed off microbiologically tight by a valve plug (25) closing contrary to the direction of flow (11) and is opened against a spring (34) in the direction of flow (11). The medium gains access to the orifice (13) via throttling elements (22, 21, 49) so that it creeps practically non-pressurized to the attaching surface area (51) of a droplet former (50) where it accumulates into a droplet suspending in the upside-down position, as a result of which the medium contained in the dispenser (1) may be protected from germ contamination and the droplet may be simply administered to an eye or the like. Instead of being formed by a plunger pump (9) the delivery and compression chamber (15) may also be formed by a tube.
