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.

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.

Abstract: A dispenser (11) with an atomizing nozzle (15) contains a medium chamber (20) with the medium (24) to be discharged. The pump plunger (21) delivering the medium (24) is hydraulically operated by the pressure of a pressure fluid (25), which is manually applied by pressure on a pressure chamber (28) constructed as a squeezing bottle or bag. Several dispensers can be jointly manufactured and sold in chain form.

Abstract: The invention relates to a device for detecting the operation of a dispenser, particularly for solid or liquid media, preferably containing at least one pharmaceutical substance, as well as to a device for discharging such media.

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.

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.

Abstract: The problem of the invention is to provide an easily manipulatable and long term-usable discharge apparatus.

Abstract: The problem of the invention is to provide a locking cap for discharge apparatuses for media, which cannot be unintentionally opened or opened by children.

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.

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).

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.

Abstract: A medium dispenser (2) includes an electric drive (30) and a mechanical lock (23) which is operated by the electrical drive (30) in response to a timed schedule stored in a memory device (36). The electric drive (30) and associated parts may be removably inserted into the medium storage portion of the unit (1). An indicator (40) is provided to signal the user through a visible or audible signal, or both, when the dispenser (1) is available for dispensing operations.

Abstract: A dispenser (1) includes a traveling member (50) extending integrally from the pump piston (17) up to the nozzle body (49) of the medium outlet (20). The traveling member (50) is enveloped by a separate runner body (60) which has handles (62). A core body (30) is located within runner body (60) and extends over the entire length of the dispenser (1). The base body (4) to be secured to the reservoir (29) is composed from two interconnected components (8,9) which commonly bound a free space (80) for stress reliefing the piston lip (17) in the operational end position.

Abstract: A dispenser (1) comprises two actuating units (2, 3) and within these actuating units (2, 3) an intermediate unit (4) which is axially shiftable relative to the actuating units (2, 3). The intermediate unit (4) receives the premeasured does of powder in a blister (5) and includes setting means (30) for forwarding the blister (5). The intermediate unit (4) further has a cylinder (51) of a pump (51), control means (79) for an outlet valve (9) of said pump (51) and means (75) for preventing withdrawal from the first unit (2). On discharge the medium is under precompression and directed into powder chamber (14) which previously was torn open by opening means (20). For replacing the blister (5) a lid (6) is tilted sidewards.

Abstract: A discharge apparatus (1) comprises within the pump housing (2) an integral full-length working member (10) having spring sections (28, 29, 30) and sections located between these which form a valve housing (18), fastening members for connecting to a piston (12) and the like. The spring section in each case may be configured as a helical or torsion spring having a closed spring jacket, thus resulting in simple manufacture and simple assembly with high functional reliability.

Abstract: For upside-down operation a metering pump (8) is provided with a displaceable cylinder (16) and a valve (19) located directly at a droplet delivery orifice (15). Vent (70) for a reservoir (6) comprise a germ filter (71). For venting the medium spaces (12, 13) actuator (20) are provided which on the return stroke of the outlet valve (19) briefly crack open. For operation in the upright normal position a suction tube may be applied to the inlet (45) of the dispenser (1).

Abstract: A dispensing container, comprising: a vessel body container and at least one reception container, the containers defining a container space sub-divided into substantially separated first and second space sections; the vessel body container defining a first container shape in the vicinity of the first space section, the first space section being adapted for receiving a first volume of a first medium; the second space section being adapted for receiving a second volume of a second medium, said first and second volumes being operationally variable; said second space section including a reception space, and being bounded by a section wall expandable to a full-size shape substantially corresponding to the first container shape, and, a pump for expelling at least one of the media with manually exerted pressure, wherein the section wall, when expanded, includes a region substantially free of tension.

Abstract: A positioning mechanism (10) with positioning members (42, 42) is located entirely within a discharge stud (7). The positioning members (42, 43) are intermeshed together through fine threads formed on the members (42, 43). An actuator (20) operates on a return stroke to open an outlet valve (19) for a short time to vent medium spaces (12, 13). The positioning mechanism (10) is adjusted to control the metered discharge of the media. A suction tube (24), a reservior seal (25) and a reservoir fastener (26) are also included within the positioning mechanism (10) in a preassembled unit (30).

Abstract: A valve (10) such as an outlet valve of a dispenser comprises a valve body (30) movable from the closing rest position in opposite directions to effect two open positions, namely e.g. one for venting a pumping chamber (8) and the other for discharging the liquid medium from this pressure chamber (8). Thereby the valve (10) opening as a function of pressure may also be automatically opened when a relative low pressure is predominant.

Abstract: A dosing device (17) for the medical administration of powder (16) through the nose or mouth has a valve body (27) which is movable in a discharge channel (22) between two valve seats (25, 26). During suction, the spherical valve body (27) is raised from the lower, container-sealing valve seat (26) and moved by a flow drag to the upper valve seat (25), so that it closes the discharge channel (22) and terminates dosing. The formation of the air/powder dispersion can be assisted in that the air subsequently sucked into the container is directed onto or into a powder supply or to a powder receiver in a pre-chamber fillable by tilting the device for pre-dosing.
