Abstract: An inlet valve (10) of a dispenser (1) or thrust piston pump, for highly reliable and speedy valve function in all vertical or inclined positions of the dispenser (1) includes, nearer to the pump chamber (20), a valve ball (35) operating in response to pressure and, further away from the pump chamber (20), a valve ball (36) subject to the force of gravity. Ball (36) pushes ball (35) out of its seat (33) in the event that it is firmly seated in the seat (33) due to a vacuum in the reservoir (9) when the dispenser (1) is turned upside down. The seats (33, 34) for the two valve balls (35, 36) are formed by a radially deformable wall (54), which can be tightly and sealingly supported against balls (35, 36).

Abstract: A discharge apparatus for media with a medium reservoir and a discharge opening for the medium is at least partly made from a plastic containing at least one substance active against microorganisms. This substance can be an antibiotic, e.g. an antibiotic with bactericidal action from the penicillin group. It is appropriate for the parts of the discharge apparatus coming into contact with the medium to be made from the plastic with additive. Preferably the discharge apparatus is substantially completely made from the plastic with additive. The discharge apparatus according to the invention is preferably used for dosing, feeding, atomizing and/or dispensing pharmaceuticals or cosmetics.

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 dispenser head (2) includes a pivotable discharge stud (17). The outlet duct (15) thereof is bounded by an inner body (22) and is located laterally adjacent to the stud axis (11). Thereby the medium may be discharged in atomized form while being multiply deflected.

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 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 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 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.

Abstract: A dispenser (1,1a) provides for filling a dosing chamber (15,15a) by gravity and then emptying it by closing an inlet valve (39,39a), by opening an outlet valve (40,40a) and by shortening the dosing chamber (15,15a) with the assistance of air flow through a discharge port (7,7a) and into a cup (80) which in one embodiment is assembled as part of the dispenser (1a) and which is removable so that its medium contents can be dispensed. Such a dispenser (1,1a) achieves a highly accurate dosing with simple handling and construction.

Abstract: For a medium pump (3) a mountable air pump (4) is provided. The stationary pump body (49) of pump (4) is fixedly connected to a member (8) provided for fixing the medium pump (3) to a reservoir (2). During the operating stroke a pressure chamber (50) of the air pump (4) permanently communicates with the reservoir (2) via the pump casing (15). Thereby pressure equalization is achieved. One and the same medium pump (3) can be provided with or without the air pump (4). When equipped with the air pump (4) the discharge of highly viscous media is significantly facilitated.

Abstract: A spiral spring (30) for a discharge device (1) is made of a plastic material with polygonal cross sections (50), and is made integral with at least one dimensionally rigid connecting body (45, 46), such that the spring (30) may also be integrated with further functional parts of the discharge device (1), thereby reducing a number of components in a discharge pump to as few as two components. The components can be produced in integral form in an injection mold before being translated into a working position with respect to each other prior to final removal from the mold.

Abstract: A dispenser (1) including a reservoir (4), a pump (6) and an atomizing nozzle (17) has on the nozzle (17) a germ barrier (22) in the form of a valve that opens and closes dependent on pressure. A further germ barrier (23) with a filter (54) acting as a seal in the connecting area between reservoir (4) and pump (6) is provided in a venting channel (21). Both units (2, 3) of the device (1), which are actuated against each other, are prevented from being pulled apart by a snap device (50). Germ penetration into the entire dispenser (1) can be effectively prevented.
