Abstract: A metering device is provided for metering at least one medium. The metering device includes a medium storage unit and a pumping system connected to the medium storage unit. The medium storage unit or the pumping system has a venting valve which is elastically held in the closed position. The metering device also includes a control member associated with the venting valve in such a way that the control member opens the venting valve as a result of a pumping movement of the pumping system.

Abstract: A metering device for at least one medium, with a medium storage unit and a pumping system connected to the medium storage unit, and in which the medium storage unit or the pumping system comprises a venting valve (44) which is elastically held in the closed position, is known. According to the invention, a control member (41) is associated with the venting valve (44) in such a way that the control member opens the venting valve as a result of a pumping movement of the pumping system. The device is used for metering a medium.

Abstract: The invention relates to a dosing device for at least one medium comprising a pump device, which is actively connected to a medium reservoir for discharging a medium, and comprising a venting device assigned to said medium reservoir. According to the invention, the venting device comprises a capillary channel, which forms a venting path between the medium reservoir and the surrounding area and whose channel length is larger by a multiple than its effective channel diameter. The inventive dosing device is provided for pharmaceutical or cosmetic purposes.

Abstract: The invention relates to a known metering device (1) for at least one medium. Said device comprises a pump unit (2), which co-operates with a medium reservoir for the delivery of said medium and an aeration device that is allocated to the medium reservoir and/or the pump unit. The aeration device comprises an aeration channel (16, 18, 26, 27), to which a filter membrane (20) is allocated. According to the invention, the filter membrane is configured for a reduced diffusion rate. The device can be used for metering pharmaceutical products.

Abstract: A discharge device for at least one medium having a medium reservoir, a medium pump and an applicator in which a filler is provided for medium guidance and which has an outlet area for a medium discharge fitted to a slender end area remote from the medium reservoir is known. According to the invention at least two outlets are provided at the outlet area. Use for medium dosing.

Abstract: In a dispenser for liquid media, applicator of the dispenser is fixed to a medium reservoir. A finger rest for actuating the dispenser is configured such that it is axially displaceable relative to this subassembly. As advantageous refinements, a dispenser is proposed whose pump is realized as a user-independent pump, a variety of mechanical realizations being considered advantageous.

Abstract: 1. Discharge device.

Abstract: A piston plunger (1) is injection molded from two longitudinal sections (2, 3) in parallel axial position. The shorter component (3) is then pivoted around a hinge joint (4) into position having the same axis as the other component (2) and tightly connected to the latter using locking means (20). The shorter component (3) then forms a nozzle core (67) and the longer component (2) forms a piercing tip (68) for opening a piston membrane (75).

Abstract: The invention relates to a dispenser for dischargeable media, preferably containing at least one active pharmaceutical substance and packed in portioned manner in storage chambers of a storage means, as well as a conveying device for the supply of the storage means. The problem of the invention is to provide a dispenser operable with one hand and able to reliably discharge the medium made available in the storage chambers. The dispenser has a punch, which can be introduced into the storage chambers. An actuating means is provided according to the invention for the dispenser. An actuation of the actuating means in the sense of performing a discharge process brings about both the positioning of a storage chamber relative to the punch and the discharge of the medium from the storage chamber.

Abstract: The invention relates to a dispenser, especially a disposable atomizer (25), with a dispenser unit (11). Said unit contains a media container (12) which also forms the pump chamber and which is sealed by a piston-type stopper (14). When activated, said piston-type stopper is punctured by a hollow needle (16). The outlet nozzle (20) surrounds the dispenser unit to a large extent. The dispenser unit (11) can be introduced into an activating unit (26). According to one configuration, this activating unit is pin-shaped with a loading chamber (29). The dispenser unit is held in place by an activating push rod (30) which can be longitudinally displaced when activated by turning (33) and is prestressed by a spring (36). The dispenser is activated by a trigger device (39). The dispenser unit (11) can also be changed after use.

Abstract: A dispenser (1) comprises a reservoir (7) and a plunger pump (8), the medium inlet (3) of which pierces a closure (45) of the reservoir (7), after which the medium can be discharged metered from the reservoir (7) by repeated strokes with the pump (8). Until used the medium thus remains hermetically sealed.

Abstract: A dispenser (1) is provided for unlocking the stroke with two first and second handles (44, 45) configured separate from the actuator handle (5) for actuating the pump stroke. For unlocking, the first handle (44) firstly needs to be actuated in a first release direction (46). Thereafter only an actuation in a second release direction (47) is possible with the second handle (45). It is not until after this second actuation that an unlocked position is attained, which permits implementation of the pump stroke. For the second motion (47) a restrain drag (43) is furthermore provided which can only be defeated by increasing the associated actuating force.

Abstract: In order to enable application of a dry i.e. powdery or granulated active substance, said substance is kept apart from a liquid supply in a dispenser. The powder is discharged with the help of said liquid during application. The liquid serves as a carrier for the active substance and is mixed with the liquid to varying degrees prior to discharge. The dispenser (11) has a liquid chamber (21) in an ampoule (19) which is provided with a closure stopper (26) which can be pierced. The liquid flow which is released upon actuation penetrates into a medium storage chamber (43), is mixed with the medium (51) therein and exits via an opened discharge outlet (44) in the form of a spray mist, jet or drop.

Abstract: In a dispenser, particularly an atomizer, which is used for flowable substances, particularly pharmaceuticals, use is made of a pump, which must be actuated one or more times for priming purposes. Its discharge nozzle (14) is covered by a protective cap (38), which is suitable to collect and store the medium, which is discharged during the priming strokes and before the start of the useful strokes. During the priming strokes the protective cap (38) is secured on the dispenser (11). This is brought about in that a locking (40) for the protective cap is only released when the priming strokes have been performed. This can take place by electrical actuation or by material change under the influence of the medium to be discharged. According to a variant the protective cap is not itself locked, but an actuation locking takes place if the protective cap has not been fitted for the priming strokes.

Abstract: The invention relates to a discharge apparatus for media. Corresponding media discharge apparatuses are e.g. generally known in the form of pump atomizers. The problem of the invention is to create a greater freedom of design for the actuation of such discharge apparatuses. This problem is solved in that the actuation direction of the actuating element of the discharge apparatus differs from the stroke direction of the pump element of the discharge apparatus.
