FIGS. 1 a and 1 b show a discharge device in a sectional view, in which the actuation of the discharge device by kinking a part of the housing opposite the main part. 1a is the unactuated starting position and in Fig. 1 b the actuated end position at the end of generating a discharge stroke.

Such a discharge device 11 has a media container 12. The Media container 12 is in or on the housing 13 of the discharge device attached. It is both possible that the housing 13 the media container 12 completely encloses and therefore not to the outside is visible. But it is also possible that, as shown, the housing only forms part of the surface of the discharge device and part forms the other Area of the media container 12, the outer surface of the discharge device 11 forms. The housing 13 is divided into two parts. For one, there is it from the main body 14 and the other part 15 Discharge opening 16 of the discharge device is formed in part 15. Of the discharge opening 16 leads a riser pipe 17 to the pump element 18 Pump element 18 shown is a piston pump. at a discharge is generated by this piston pump in that the pump chamber is reduced in volume. This happens because the Part 15 of the housing about the pivot axis 19 relative to the main body 14 of the housing 13 is pivoted. The swivel axis runs 19 at right angles to the line of movement of the piston in the pump element 18. Thus, part 15 of housing 13 is in a direction transverse to the direction of actuation of the pump element 18 runs, pivotable. When swiveling of the part 15 about the pivot axis 19 that becomes this Purposes not completely rigid riser 17 in the area of Swivel axis 19 slightly bent. The actuation of the pump element 18 here the displacement of the pump piston in the housing towards the Container 12, takes place in that a driver during the pivoting movement acts on the deflecting means 20. Through the deflecting means 20 a force in the direction of the actuation direction of the pump element 18 for generation generated a discharge stroke and thereby actuated the pump element 18. A complete stroke of the pump element 18 is generated when the part 15 by a predetermined angle alpha to the main body 14 is pivoted. The angle alpha lies in a range between 35 °, here is shown an angle of alpha = 15 °. Through the discharge stroke is the medium from the pump element beyond the riser conveyed to the discharge opening 16 and discharged there.

Is either by suitable restoring means, e.g. Return springs, the part 15 automatically or by manual actuation back into its in Fig. 1a Returned starting position shown, so is medium from the media container 12 sucked into the pump element 18. The medium sucked in is now available for the next discharge stroke. The for this in the Rule provided, at least approximately to the lowest point of the media container leading suction line is omitted in the schematic representation.

The media container 12 can in particular be a glass container act. The glass container usually has an opening, through which it is filled with medium. This opening is mostly through the Pump element 18 closed, so that no further closure for the glass container necessary is. Furthermore, it is also not necessary a special passage for the intake of a pump element or to provide an attachment point of a pump element separately.

2 shows an alternative discharge device in a partially sectioned illustration, the area of the media container from the discharge device 11 12 is not shown in full.

The media container 12 forms part of the surface of the discharge device 11. The media container 12 has at its upper end before it tapers towards the filling opening, a circumferential groove 20 in which the housing 13 is held by locking.

The filling opening 21 of the media container, which is preferably a glass container is in the form of a nozzle, for example on the outside has a thread or a detent, via which a fastener 22, here a corresponding sleeve, at the filling opening can be set. Through the fastener 22, the pump element 18, again for example a piston pump, in the housing 13 arranged on the media container 12 is attached such that the intended Seal and the pump element close the filling opening 21. In the interior of the housing extends from the pump element to the discharge opening 16 the riser pipe 17. This riser pipe 17 is dimensionally stable. It gives a fixed distance between the discharge opening 16, which on the housing 13 is formed and movable parts of the pump element 18, which the generation serve a discharge stroke, in particular the piston.

The portion of the housing 13 that has the discharge opening 16 becomes here, for example for aesthetic or hygienic reasons Cover 24 closed, which can be snapped onto the housing 13. The lid covers the discharge opening 16 and is before the discharge device is used to decrease.

The actuating element 24 is used to actuate the media container Actuating element 24 is on the swivel arm 25 in the housing side trained abutment 26 pivotally held. Points to the outside the actuating element 24 has a particularly ergonomically shaped handling surface 27 on. From the surface forming the handling surface 27 an active element 28 projects inwards towards the fastening means 22 aligned from. The actuating element 24, consisting of Swivel arm 25, handling surface 27 and active element 28 forms one Pivoting lever. If this lever is applied by force in the direction of force direction of the force vector F indicated by the arrow through the The user actuates the actuating element 24 around the abutment 26 panned around. A front, correspondingly bevelled engagement edge 29 in contact with the contact surface 30 of the fastener 22. If the actuation movement is now continued, because of the bevels of the surfaces there is a force is exercised on the media container 12, which together with the attached therein Pump element in the direction of the discharge opening 16 - upwards - pushes. To generate this movement of the media container in the direction on the discharge opening 16, it is not absolutely necessary that the Active element 28 with its engaging edge 29 on the fastening means 22 attacks. The media container 12 could also be designed differently that it has a bead which is engaged by the active element and during the corresponding lifting movement of the media container 12 generated. In this sense, the fastening means 22 is also a bead to view the media container 12. In principle, it is only necessary that between the active element 28 and the media container an axial Thrust can be generated in the direction of the orientation of the riser 17 acts.

Thus, the direction of actuation of the actuator 24 is different from the stroke direction of the pump element 18. The discharge stroke is as follows generated: by means of the actuating element 24 on the media container 12 initiated thrust, this "up" towards the Discharge opening 16 pushed. Since the riser pipe 17 is dimensionally stable, can be the distance between the moving parts of the pump element 18, on which the riser pipe 17 is supported and the discharge opening 16 is not reduce. The corresponding support force is applied to the moving parts of the pump element 18 and thereby a media discharge, in particular by immersing a plunger in a pump chamber. As soon as the actuating element 24 is released, that is to say the actuating force no longer acts on it, for example, in the pump element 18 arranged return spring of the media container 12 back in its Starting position returned. The weight can also support this Act. For example, by a return spring, the actuator 24 pushed back into its starting position, as shown.

In addition, it is possible that between the actuating element 24 and an elastic molded part is arranged in the housing 13. This elastic Molded part ensures that the inside of the housing 13 on all sides is completely enclosed. The tight closure by the molded part, which in 2 is not shown, prevents contamination and damage in the Interior of the housing.

A further embodiment of the invention is shown in FIGS. 3a to 3c.

The discharge device 11 is shown in FIG. 3a, FIGS. 3b and 3c each show a side view of the pump element and a top view 18 and the actuating element 24 with its active element 28.

The discharge device 11 is formed from a media container 12 which partially forms the outer surface of the discharge device 11 and the housing 13, which connects flush to the media container 12. So that the discharge device 11 can be parked on a flat surface is one Provided receptacle 31 that the discharge device 11 can accommodate and from which the discharge device 11 can be removed. The recording 31 can, for example, similar to a spherical cap with a recess for receiving of the discharge device 11.

The media container 12 has a cavity into which the medium 32 is filled is. The medium can - and this also applies to the others in of the drawings shown in the same way applies - by one Act liquid as shown here. The liquid can either for pharmaceutical or cosmetic purposes, or both Serve purposes at the same time. For this purpose, the medium can in particular be pharmaceutical Contain active ingredients. But it is also possible that it is the medium 32 only around a liquid with cosmetic purposes, for example a perfume or eau de toilette.

The housing 13 with the discharge opening 16 encloses the area of the media container 12, which has its fill opening 21. The filling opening is closed by the pump element 18. The pump element 18 is there arranged in a fastening means 22, which also has a seal 23 for hermetically sealing the filling opening 21. Held in there is the pump element 18. The fastening means 22 is, for example held on the media container 12 via locking means. From the pump element 18 leads a riser pipe 17 to the discharge opening 16 on the housing 13. On the housing 13 or alternatively on the media container 12 around the The actuating element 22 is pivotably mounted on the pivot axis 19 it is a toggle switch-like actuator. When actuating the toggle switch with an actuating force accordingly the force arrow F becomes an actuating force via the active element 28 generated in the sense of generating a discharge stroke. This discharge stroke is generated by a force directed in the direction of the force arrow H. The force for the discharge stroke runs in the alignment of the axis of the pump element 18 and in the axis of the riser pipe 17th

From Fig. 3b it can be seen that the active element 28 is a Slide path 33 is in which the sliding block 34 is guided. The sliding block 34 is either formed directly on the pump element 18 or on the riser pipe 17, which is indirectly connected to the pump element 18 and can act on its moving parts. By pivoting the actuating element 24 about the pivot axis 19, the sliding block in the guideway guided so that a force is generated in the direction of force H. The other force components that act on the sliding block 34 must be caught by the construction of the pump element 18. The discharge stroke can be generated in particular by the fact that the sliding block is connected to the piston of the piston pump and this down, in Pushes towards the pump chamber so that its volume is reduced will be carried out. The medium 34 then passes through the Riser pipe 17 to discharge opening 16.

So that medium is safely sucked into the pump chamber of the pump element 18 a suction line 35 leads from the pump element 18 to the bottom of the Media container 12. This ensures that as much media as possible 32, which is stored in the media container 12, by the pump element 18 is portable. With such a dispenser it is also possible to use the actuating element in one piece, for example by using appropriate Multi-component injection molding process. An elastically deformable Molding can cover the actuating element 24 or positively concern him. It is also possible that the injection molding Whole unit of housing 13, molded part and actuating unit 24 together are produced and are coherent.

FIGS. 4a to 4d each show an alternative in a schematic representation Embodiment of the invention shown. 4a shows one Sectional view through the discharge device, Figures 4b and 4c Actuator and the holding means and Fig. 4d in a schematic partially sectioned representation of an embodiment of the discharge device with actuation protection.

4a shows the discharge device 11 in a partially sectioned illustration. In this discharge device, a housing 13 is provided which the outer Surface of the discharge device forms. Inside the housing 13 is the media container 12 is arranged with the medium contained therein. On a discharge opening 16 is also formed in the housing 13. The The discharge opening is in an application area formed on the housing 13 arranged. The application area 36 serves the application to facilitate the medium at the desired application location. For example, this is the case when the medium is applied intranasally should, as is the case for example with pharmaceutical active ingredients Media may be the case. Media that are applied intranasally include migraine, headache and other pain relievers, which enter the bloodstream quickly and effectively through the nasal mucous membranes can and for which therefore the nasal cavity is a preferred location is.

The riser pipe 17 leads from the discharge opening 16 to in this drawing Pump element 18, not visible. For actuating the discharge device 11 serves the actuating element 24 designed as a lever the pivot axis 19 received between the two housing halves arranged pivotally in the housing 13. The actuator 24 is made a handling surface 27 and a retaining ring 38.

The media container 12, which is preferably a glass container, has a filling opening. This fill opening is by means of the Pump element 18 closed. Sealing around the pump element on the filling opening the pump element is to be fastened by means of a crimp sleeve 39 if necessary, using a stopper or other sealant, permanently and tightly attached to the medium. The media container 12 is thereby fixed in the housing 13 that he in the retaining ring 38 of the actuator 24 is held.

To actuate the discharge device 11 is one in the direction of the user the force arrow F acting force on the handling surface 27 bring the actuator 24. By pivoting the actuating element 24 about its pivot axis 19 with one in the Direction of the force arrow H force of the media container 12 over the Holding means 37 acted towards the discharge opening. Because the riser 17 is dimensionally stable and opposite to the media container 12 the force direction H movable parts of the pump element 18 are supported there is a relative movement of the media container to the riser pipe 17. By moving the moving parts of the pump element 18 a discharge stroke is generated.

4b shows the actuating element 24. With respect to the pivot axis 19 of the actuating element 24, which on the housing side in corresponding Is held abutment, the handling surface 27 forms a lever arm to generate a pivoting movement, that is, an actuation of the actuating element. The retaining ring projects at an angle to the handling surface 27 38 from the pivot axis 19. The retaining ring is around an open ring in which the holding means 37 shown in Fig. 4c are insertable into the retaining ring and securely held in the retaining ring 38 can be. For this purpose, the ring segments 38a and 38b are spread apart, after insertion of the holding means 37, these are in one Angular range encompassed by the ring segments 38a and 38b, the larger than 180 °. So that the flanged ring 40 of the holding means 37 is securely gripped is, is a corresponding, tapered, bevelled behind Inclined surface formed on the retaining ring.

4c, the holding means 37 is shown. It is a modified crimp sleeve 39. The crimp sleeve 39 fastened in the usual manner the pump element 18 and possibly additional sealing means, such as a rubber stopper, in the filling opening 21 of the media container 12. The free ends of the For this purpose, crimp sleeve 39 is formed by an appropriately trained, in the Drawing not shown bead in the region of the opening 21 of the media container 12 bent so that a tight fitting for the Pump element 18 and possibly the sealant is achieved. By this type of attachment can be a media-tight attachment of the pump element 18 can be reached in the filling opening. About the usual design of a crimp ring, the holding means 37 has a standing collar 41 on the side of the crimp sleeve facing away from the media container 12 protrudes. The standing collar 41 is delimited by the flange ring 40. alternative a different diameter extension could also be added to the flare ring, like a bead. The crimp ring 40 can easily from the inclined surface 42 of the retaining ring 38 can be engaged. A power transmission in Axial direction, that is, in the orientation of the standing collar 41 is easily possible.

4d shows the discharge device 11 of FIG. 4a in a side view shown. The housing 13 of the discharge device 11 is in the area of the actuating element 24 and in the application area 36 of the cover 43 covered. The cover 43 is in particular by a snap connection held on the housing 13. The fact that the cover 43 Actuating element 24 covered with its handling surface 27 is a effective protection against unintentional actuation of the discharge device 11 created.

Figures 5a and 5b show a further embodiment of the invention. 5a shows the starting position secured against actuation, while in the partial view 5b of the device the position ready for actuation of the actuator is shown.

The discharge device 11 has a housing which is in a main body 15 and divided into a part 15 of the housing 13. The division of the Housing is done in two parts so that the media container 12 in easier Way can be exchanged. The part 15 is by a snap connection 44 connected to the main part 14. Also in this embodiment the media container 12 is completely hidden in the housing 13. The main part of the housing has the discharge opening 16, from which leads to the pump element 18, a rigidly formed riser pipe 17 by means of the crimp sleeve 39 on the filling opening 20 of the media container 12 is attached in a fluid-tight manner.

The media container 12 is guided in the main body 14 of the housing 13 held. It is axially displaceable in the direction of the discharge opening 16. When moving is indirectly via the riser 17 on the movable Parts of the pump element 18 acted so that a discharge stroke is generated. The actuating element 24 serves to actuate the discharge device 11, which is arranged pivotable about the pivot axis 19. 5a is the actuating element 24 in a position, for example by latching held in which a direct actuation of the discharge device is not possible is. So it is a storage or transport position, at which prevents unintentional actuation of the discharge device he follows.

By pivoting the actuator 24 into the position as in 5b is shown, the operational readiness of the discharge device 11 given. The actuating element 24 has a handling surface 27 in which the user initiates the actuating force. The distance between Place of force and pivot axis 19 results in a lever arm. At the side of the actuating element 24 facing away from the handling surface 27 a contour line 45 is formed, which is the contact of the actuating element specifies on the deflection means 46. Due to the curvature of the contour line 45 there is a different distance between the contact point and the actuating element 24 on the deflection means 46 to the pivot axis 19 of the actuating element and the distance of this contact point to the pivot axis 47 of the Deflection means 46 changed. This makes the leverage ratio variable designed. The contour line 48 of the deflection means 46 is also corresponding to this shaped. By changing the leverage ratio it is possible a different gear ratio that can be changed depending on the actuation path between the actuating force of the actuating element and to generate the force acting on the media container.

The deflection means 46 is itself a lever in the embodiment shown (Cam), which is pivotable about the pivot axis 47, is formed. In addition to establishing a suitable gear ratio between Actuating element 24 and media container 12 serves the deflecting means 46 mainly to redirect the direction of force so that the main component the force in the direction of the force vector H of the drawing, that is, in the direction is introduced into the discharge opening 16 in the media container 12. Due to the force acting, the container 12 is in the direction when actuated pushed onto the discharge opening and with as possible a transverse force component free force application. Nevertheless, it is possible to use the media container to lead axially in the housing 13. It also ensures Deflection means 46 the media container 12 in the housing against slipping or falling out. This is necessary because the media container 12 is not fixed in the housing 13, but relatively movable to this is so that a discharge stroke of the pump element by axial displacement possible in the direction of the direction vector H of the media container 12 is.

6 shows a discharge device, which is also operated of actuators 24 produces a discharge of medium. In the housing 13 closed with the cover 43 is the media container 12 arranged. Whose filling opening 21 is closed by the pump element 18. The pump element is used to generate a discharge stroke actuated the actuators 24. Each of these actuators works on a toothed washer 50 which extends over at least part of its outer radius has a tooth segment. Both actuator 24 and Toothed washer 50 are each pivotable about an axis. there are arranged in the housing 13 two actuators, each of which a toothed pulley 50 is assigned. The two actuators are symmetrical to each other with respect to the central axis of the discharge device arranged.

A coupling between the two tooth lock washers and thus also one Coupling between the two actuators is achieved that this is on a movable pump element, which by an axial stroke a media issue can intervene, that against both Toothed washers is designed as a rack 49. This embodiment enables that the media container as a whole is stationary in the housing 13 is arranged. The power transmission between actuators 24 and Pump element takes place via the interlocking teeth of Rack 49 and toothed washers 50. The deflection also takes place here the direction of force. The toothed disks 50 and the rack 49 form one Toothed gear.

The embodiments of Figures 7a and 7b and Figures 8a and 8b in contrast to the previous figures show discharge devices 11, in which the actuating element 24 is axially guided and not pivotable is.

Figures 7a and 7b show one in the unactuated or actuated position Discharge device 11 with an actuating element 24 on the for actuation of the pump element 18 a slide 51 is formed. The slide 51 has a bevelled engagement edge 52 which corresponds to a trained flank 53 of the movable part of the pump element acts. Engagement edge 52 and flank 53 slide when the actuating element is actuated 24 to each other. Characterized in that the actuating element 24 is guided axially is and this in the transverse direction of the direction of extension or stroke of the Pump element 18 is a directional deflection of the force effect on the generated on both sides. A discharge hub and thus a media discharge via the riser pipe 17 to the discharge opening 16 can be generated. At least there is one of the active elements engaging edge 52 and flank 53 as an inclined surface designed to redirect the operating force. The slopes the flanks to each other determine a translation and thus the Relationship between actuation path and required actuation force.

The actuating element 24 is in the housing 13 of the discharge device 11 arranged. The media container 12 forms in the illustrated embodiment again part of the outer surface of the discharge device. The discharge opening 16 is arranged in an application area 36 of the housing 13. A is used to generate the linear guidance of the slide 51 Support beam 54, which also supports the slide accordingly 51 ensures that the operating force without loss in an operation of the Pump element is implemented.

So that the best possible power transmission takes place and possible lateral force components can be balanced, it is possible on both sides of the pump-pump element and thus also one on both sides of the riser tube 17 Provide slider 51, which then also each on an edge 53 of the Pump element 18 acts. It is also in such an embodiment possible that between the actuator 24 and the housing 13 an elastic Molded part ensures a hermetic connection and an external one flat closed contour generated.

A discharge device 11 is shown in FIGS. 8a and 8b, in which the actuating element 24 can be actuated linearly, the actuation of the Pump element takes place by means of a guide link. 8a a sectional view through the discharge device 11, Fig. 8b is a view the guide link and its action on the pump element 18.

The discharge device 11 has a media container 12 which is in the the housing 13 enclosing the media container 12 is arranged. The Container 12 is in the region of its filling opening 21 by the pump element 18 closed. For this purpose, the pump element 18 is inserted into the filling opening 21 and is held therein by the fastener 22. It is also possible that a seal for good sealing of the fill opening 21 23 is provided. The pump element 18 is a piston pump. The rigid riser tube 17 acts as the connection between the pump element 18 and the discharge opening 16 in the housing 13 forms, on which the pump chamber of the pump element 18 is immersed Pump piston and can be used to generate a discharge stroke transfer the required force to it. The riser pipe 17 is coaxial arranged to extend the piston pump. So as complete as possible The medium 32 is sucked in by the pump element 18 can, the suction line 35 is provided, which is at least almost up to Bottom of the media container 12 leads. This can be conveniently Housing 13 accommodate all elements except the container 12 to be filled and are prefabricated as a unit. The housing 13 is then on placed the media container 12, the connection between the pump element 18 and fill opening 21 serves as an attachment. The connection can for example, be designed as a snap or screw connection.

The actuation of the actuating element 24 takes place essentially in the direction whose surface normal, corresponding to that shown in the drawing Force arrow F. For this purpose, the actuator is mounted so that it is linearly movable in the housing. The actuating element 24 in the type of a button that is operated by pressing. So that one good completion of the through opening required for the actuating element 24 55 is given, it is possible to provide a material layer 56 which is an elastically deformable connection between the actuating element 24 and the housing 13 forms. The handling surface 27 the actuating element 24 can also be made of this material layer be formed, which can also serve a pleasant grip to generate when actuating the actuating element 24.

The active element 28 of the actuating element 24 is a guide link 33 educated. A slide block 34 formed on the riser pipe 17 is in the Leading link 33 out. For good linear guidance and support of the forces in the housing 13, the support body 58 is provided, which has a guideway 57 in which the sliding block 34 also is led. The support body 58 can either directly with be connected to the housing 13 or to the fastening means 22 be formed or integrally formed, the fastening means 22 at least is indirectly supported on the housing 13.

If the actuating element 24 is actuated in the direction of the force vector F, so it is shifted straight, linear. A possible layer of material 56 would then have to deform elastically. The active element 28 would also be linear be moved. The linearity of the movement is at least partly via the support of the sliding block 34 in the guideway 57 generated. The sliding block 34 guided in the guide link 33 is due to the shape of the slide track 33, e.g. designed approximately in the shape of a segment of a circle is, in the direction of the pump element 18 down, along the through the stroke vector H given direction. The on the active element 28 also transferred lateral force component acting on the sliding block 34 is supported in the guideway 57. So that is through a Actuation of the actuator 24, the volume of the pump chamber 59 of the pump element is reduced in that the piston 60 from the riser 17 is pushed down. About the volume reduction of the Pump chamber 59 is therefore a media discharge generated. At the end of the operation the actuator is released. Due to the on the actuator 24 at least indirectly acting restoring forces, for example generated by a return spring, this is back in its Starting position moved back, as shown in Figs. 8a and 8b. For this purpose, corresponding actuation can also be carried out in the pump chamber 59 counteracting return springs may be provided. Alternatively it would also be possible to place the energy accumulator in another way on the pump element 18 provided. During the return movement, the volume of the pump chamber 59 enlarged again and thereby 35 medium via the suction line sucked.
