Abstract: A first reservoir body (13) includes two necks (19, 20). One neck (19) carries a thrust piston pump (11) including a medium outlet (37). The other neck (20) carries a closed second reservoir body (14) including a second medium. When the closure (9) is opened, the second medium is transferred into the first reservoir body (13) where it is mixed with or dissolved in the first medium. Thereafter, the mixed media can be discharged by the dosing pump (11) from the first reservoir body (13) in discrete doses in sequence. Thus, the media are stored separately and are not merged until being discharged.

Abstract: Such dispensers must be easy to grasp or operate by a user, e.g. a user suffering from rheumatoid arthritis and whose capacity to manipulate objects is under certain circumstances limited. In addition, the dispenser must have a simple, inexpensive construction from a minimum number of components. The dispenser is used for the discharge of media, particularly fluids, e.g. a liquid, which preferably contain a pharmaceutical substance, as described in exemplified manner hereinbefore. In the case of the dispenser, the medium is discharged in at least two proportioned partial charges by actuating an actuating means. As a result of the actuation of the actuating means, a relative movement is produced between the actuating means and a housing having a dispenser discharge opening. According to the invention an elastically deformable material bridge is provided. The actuating means is held on the housing by means of the elastically deformable material bridge.

Abstract: The discharge head of the dispenser (1) comprises a supporting body (9) and a head body (3) pivotable relative to the latter by a pliant connection (40), namely an elastomeric passage section (47), including the delivery orifice (53). The bending of the passage section (47) is guided by a single-axis joint (50) and due to the pivoting movement an actuating finger rest (55) becomes accessible for manually actuating a discharge stroke of a pump (20).

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 two-way valve, especially for liquid dispensers. The inventive valve comprises connections (1,2,3) for a liquid reservoir (1a), for a pump and for a liquid consumer. A membrane disk (4) is clamped between a valve housing (5) and a cover housing (6) and lies flat against a surface of a ring seat (10) in whose range (7) an axial opening (8) is located. Said membrane disk (4), at the cover end, lies flat against the surface of a counter ring seat (6a) that has the same diameter. The aim of the invention is to provide, based on a two-way valve, a system with a spring-loaded piston that deviates from the steel ball compression spring system. To this end, an additional two-side gripping (9) of the membrane disk (4) is used that consists of the surface of the counter ring seat (6a) and the surface of a ring seat (2a). In addition to this supplementary clamping (9) a first ring channel (11) is configured which opens into the third connection.

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: Disclosed is a dispenser for liquids or for viscous or sprayable products to which a disposable container is tightly attached and to which a dosage device is attachable. The inventive dispenser is provided with a cylinder-housing (3), suction or compression cylinders which can be moved back and forth (1) and a valve between the suction and pressure cylinders. For the purpose of producing a dispenser suitable for liquids of differing consistencies which avoids contact between the liquid and metal parts and the invasion of bacteria in the air, the invention proposes that the cylinder housing at one end accommodates the cylinder (1) which has a pressure spring (2) located in a recess and that at the other end a valve seat (5) is provided with a membrane disk (4) which is stretched at the periphery thereof in order to close off the container or open the through-flow from said container.

Abstract: The invention relates to a discharge apparatus for media. In the case of such discharge apparatuses the medium to be discharged is stored in a container, which has chambers separated from one another. Into each of the chambers is introduced at least one media component and the media components together form the medium to be discharged. The container is placed in a casing having a discharge opening for discharging the medium. An actuating means movable relative to the casing is provided. Through the actuation of the actuating means firstly a connection between the chambers of the container is produced.

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: 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 device for detecting the operation of a dispenser (11) includes a medium container (12) for storing a dischargeable medium, a discharge mechanism (13) operated by a relative movement between an operating element (14) and the medium container, the operating element (14) containing a detecting device (20) for detecting operations which have taken place and for generating an electric counting signal in response thereto, the operating element (14) also containing a display element (22) for displaying a numerical value determined in the counting mechanism (21) as a function of the number of counting signals which have occurred and the display element (22) only being activated for a period of time.

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 smart fragrance dispensing device (1) has an airless fragrance reservoir (1a) containing a principal medium (8), a flow channel (3) for receiving the principal medium (8), a liquid spray dispenser (2) connected to the reservoir (1a) for dispensing the principal medium (8) as a spray into the flow channel (3), a programmable driving circuit (5) for operating the liquid spray device so as to create the spray consisting of monodispersive droplets, a memory device (4) carrying and communicating identification information about at least the principal medium (8), its dispensing and diffusing characteristics, the liquid spray dispenser (2) and the reservoir (1a), and a programmable control and communication micro-controller unit (7) linked to the reservoir (1a), the information being used to adapt to the individual perception of a user by adjusting to a desired level and memorizing the level.

Abstract: The problem of the invention is to so develop known dispensers, that it is possible to very precisely determine the actual discharged medium volume.

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.
