Such a discharge device 11 has a media container 12. The media container 12 is in or on the housing 13 Discharge device attached. It is both possible that the Housing 13 completely encloses the media container 12 and this so that it is not visible to the outside. But it is also possible that how shown the housing only partially the surface of the Discharge device forms and in another area of Media container 12 forms the outer surface of the discharge device 11. The housing 13 is divided into two parts. For one, it consists of the main body 14 and the other part 15 Discharge opening 16 of the discharge device is formed in part 15. A riser pipe 17 leads from the discharge opening 16 to the pump element 18. The pump element 18 shown is a Piston pump. With this piston pump, there is a discharge produces that the pump chamber is reduced in volume. This happens in that the part 15 of the housing about the pivot axis 19 relative to the main body 14 of the housing 13 is pivoted. The pivot axis 19 extends in the right Angle to the line of movement of the piston in the pump element 18 the part 15 of the housing 13 in a direction transverse to The direction of actuation of the pump element 18 is pivotable. At the Swiveling the part 15 about the pivot axis 19 is too this purpose not completely rigid riser 17 in Area of the pivot axis 19 slightly bent. The actuation of the Pump element 18, here the displacement of the pump piston in Housing in the direction of the container 12, is done in that during a driver acts on the deflection means 20 of the pivoting movement. A force in the direction of the Operating direction of the pump element 18 to generate a Discharge stroke generated and thereby actuated the pump element 18. On complete stroke of the pump element 18 is generated when the Part 15 by a predetermined angle alpha to that Main body 14 is pivoted. The angle alpha is in one Range between 35 °, here is shown an angle of alpha = 15 °. The discharge stroke removes the medium from the pump element conveyed via the riser pipe to the discharge opening 16 and discharged there.

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

The media container 12 can in particular be a Trade glass containers. The glass container usually has one Opening through which it is filled with medium. This opening will mostly closed by the pump element 18, so that no further Closure for the glass container is necessary. Furthermore, it is therefore also not necessary, a special passage point for the Intake of a pump element or an attachment point of a Provide pumping element separately.

Fig. 2 shows an alternative discharge device in a partially sectioned Representation, the area of the discharge device 11 Media container 12 is not shown completely.

The media container 12 forms part of the surface of the Discharge device 11. The media container 12 has on its upper End, before it tapers towards the filling opening, a circumferential groove 20 on, 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 that is attached to it Outside, for example, a thread or a detent has a fastening means 22, here a corresponding one Sleeve, can be fixed at the fill opening. By the Fastening means 22 becomes the pump element 18, again for example a piston pump, arranged in the housing 13 the media container 12 is attached such that the intended Seal and the pump element close the filling opening 21. In the housing interior extends from the pump element to Discharge opening 16 the riser pipe 17. This riser pipe 17 is dimensionally stable educated. There is a fixed distance between the discharge opening 16, which is formed on the housing 13 and movable parts of the Pump elements 18, which are used to generate a discharge stroke, that is especially the piston.

The section of the housing 13 which has the discharge opening 16 is used, for example for aesthetic or hygienic reasons closed by a cover 24, which on the housing 13th can be snapped on. The lid covers the discharge opening 16 and is to be removed before using the discharge device.

The actuating element 24 serves to actuate the media container. The actuating element 24 is in the Abutment 26 formed on the housing side is pivotally held. to On the outside, the actuating element 24 has a particular ergonomically shaped handling surface 27. From which the An active element 28 protrudes from the surface forming the handling surface 27 aligned towards the inside of the fastening means 22. The Actuator 24, consisting of swivel arm 25, handling surface 27 and active element 28 forms a pivot lever. Will this Swivel lever by applying force in the direction of the arrow specified direction of force of the force vector F by the user actuated, the actuating element 24 around the abutment 26 panned around. One arrives in the course of the swiveling movement front, correspondingly bevelled engagement edge 29 in contact with the Attack surface 30 of the fastener 22. Will the actuation movement now continued, the slope results in the Areas that a force is applied to the media container 12, the this with the pump element fastened in it in the direction of the Discharge opening 16 pushes upwards. To generate this movement of the media container in the direction of the discharge opening 16 it is not absolutely necessary that the active element 28 with its Engagement edge 29 engages the fastener 22. The media container 12 could also be designed differently so that it has a bead has, which is engaged by the active element and during Behind the corresponding lifting movement of the media container 12 generated. In this sense, the fastening means 22 is also Bead of the media container 12 to look at. 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 alignment 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 generated as follows: By means of the actuating element 24 on the Media container 12 initiated thrust this "up" in Pushed towards the discharge opening 16. Since the riser pipe 17th is dimensionally stable, the distance between the movable parts of the pump element 18 on which the riser pipe 17th is supported and not reduce the discharge opening 16. The corresponding Support force is applied to the moving parts of the pump element 18 initiated and thereby a media release, in particular by the Immersion of a plunger in a pump chamber. As soon as the actuating element 24 is released, that is Actuating force no longer acts on it, for example, by im Pump element 18 arranged return spring of the media container 12 returned to its original position. Here, the Weight strength support. For example, by a Return spring, the actuator 24 is back in its Starting position pushed back as shown.

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

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

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

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 is placed on a flat surface can be, a receptacle 31 is provided, which the Discharge device 11 can accommodate and from which the discharge device 11 is removable. The receptacle 31 can for example Similar to a spherical cap with a recess for receiving the Discharge device 11 may be formed.

The media container 12 has a cavity into which the medium 32 is filled. The medium can - and this also applies to the other designs shown in the drawing in the same way applies - act as a liquid, as shown here. The Liquid can be either pharmaceutical or cosmetic Serve purposes or for both purposes at the same time. This can the medium contain in particular pharmaceutical active ingredients. It it is also possible that the medium 32 is only one 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 The filling opening is closed by the pump element 18. The Pump element 18 is arranged in a fastening means 22, which also a seal 23 for hermetically sealing the Has filler opening 21. The pump element 18 is held therein Fastening means 22 is on the locking means, for example Media container 12 held. Introduces from the pump element 18 Riser pipe 17 to the discharge opening 16 on the housing 13. At the Housing 13 or alternatively to the media container 12 around the The actuating element 22 is pivotably mounted on the pivot axis 19. It is a toggle switch Actuator. When the toggle switch is operated with a Operating force according to the force arrow F is about Active element 28 an actuating force in the sense of generating a Discharge strokes generated. This discharge stroke is caused by a force that is in Direction of the force arrow H is generated. The power for the 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 is a slide track 33, in which the sliding block 34 is guided. The Sliding block 34 is either directly on the pump element 18 molded or formed on the riser 17, the indirect can act on the pump element 18 and its moving parts. By pivoting the actuating element 24 around the Pivot axis 19, the sliding block is guided in the guideway so that a force is generated in the direction of force H. The other power components, that act on the sliding block 34 must by the Construction of the pump element 18 can be collected. The discharge stroke can be generated in particular in that the Sliding block is connected to the piston of the piston pump and this down, pushing towards the pump chamber so that its Volume is reduced and thus a discharge takes place. The medium 34 then passes through the riser pipe 17 to the discharge opening 16.

So that medium is safely into the pump chamber of the pump element 18 is sucked in, a suction line 35 leads from the pump element 18 to Bottom of the media container 12. This ensures that as possible all medium 32, which is stored in the media container 12, by the pump element 18 can be discharged. Even with such a donor it is possible to integrally, for example, by the actuating element To use appropriate multi-component injection molding processes. The actuating element can be an elastically deformable molded part 24 cover or fit against it in a form-fitting manner. It is also possible that the entire assembly of housing 13, Molding and actuator 24 are made together and are coherent.

Within the Housing 13 is the media container 12 with the contained therein Medium arranged. On the housing 13 is also a Discharge opening 16 formed. The discharge opening is in a Housing 13 molded application area arranged. The Application area 36 serves to apply the medium to the to facilitate the desired application site. This is then, for example the case when the medium is to be applied intranasally, such as this is the case, for example, for media containing pharmaceutical active ingredients may be the case. Media that are applied intranasally are for example migraine drugs, headache and other pain relievers, which quickly and effectively enters the bloodstream through the nasal mucosa can enter and for which therefore the nasal cavity preferred place of delivery.

The riser pipe 17 leads from the discharge opening 16 to the latter Drawing not visible pump element 18. To actuate the Discharge device 11 serves the actuating element 24. This is over the pivot axis 19 is pivotally arranged in the housing 13. The Actuating element 24 consists of a handling surface 27 and a retaining ring 38.

The media container 12 is fixed in the housing 13 in that it Retaining ring 38 of the actuating element 24 is held.

To actuate the discharge device 11, the user must Direction of the force arrow F force acting on the handling surface 27 to bring the actuator 24. By pivoting of the actuator 24 about its pivot axis 19 with a force of the media container acting in the direction of the force arrow H. 12 via the holding means 37 in the direction of the discharge opening applied. Since the riser pipe 17 is dimensionally stable and on movable relative to the media container 12 against the direction of force H. Parts of the pump element 18 is supported, there is a relative movement of the media container to the riser pipe 17. By moving the A discharge stroke is generated for moving parts of the pump element 18.

With respect to the Swivel axis 19 of the actuating element 24, which is on the housing side is held in appropriate abutments, forms the handling area 27 a lever arm for generating a pivoting movement, that is an actuation of the actuating element. At an angle to that Handling surface 27 protrudes retaining ring 38 from pivot axis 19 from. The retaining ring is an open ring in which the Holding means 37, which are shown in Fig. 4c, insertable into the retaining ring are and can be held securely in the retaining ring 38. To do this the ring segments 38a and 38b spread apart after the The holding means 37 are introduced in an angular range of encompassed the ring segments 38a and 38b, which is greater than 180 °. So that the flanged ring 40 of the holding means 37 is securely engaged a corresponding, tapered, bevelled rear grip Inclined surface formed on the retaining ring.

4c, the holding means 37 is shown. It is about a modified crimp sleeve 39. The crimp sleeve 39 attached in the usual Way the pump element 18 and possibly additional sealant, such as a Rubber stopper, in the fill opening 21 of the media container 12. Die Free ends of the crimp sleeve 39 are corresponding to this trained, not shown in the drawing bead in the area of Opening 21 of the media container 12 is bent so that a firm attached attachment for the pump element 18 and under certain circumstances the sealant is achieved. With this type of attachment, a media-tight attachment of the pump element 18 in the fill opening can be achieved. About the usual design of a crimp ring In addition, the holding means 37 has a stand-up collar 41 on which the Media container 12 protrudes away from the side of the crimp sleeve. The Standing collar 41 is delimited by the flange ring 40. Alternatively to that Crimp ring could also have another diameter extension, such as a bead, be formed. The crimp ring 40 can well from the Inclined surface 42 of the retaining ring 38 can be engaged. A Power transmission in the axial direction, ie in the orientation of the Standing collar 41 is easily possible.

4d, the discharge device 11 of FIG. 4a is in one Side view shown. The housing 13 of the discharge device 11 is in the area of the actuator 24 and Application area 36 covered by the cover 43. The cover 43 is in particular by a snap connection on the housing 13 recorded. In that the cover 43 also the actuator 24 covered with its handling surface 27 is an effective one Protection against unintentional actuation of the discharge device 11 created.

FIGS. 5a and 5b show a further embodiment of the Invention. 5a is the starting position secured before actuation shown, while in the partial view 5b of the device position ready for actuation of the actuating element 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 The housing is divided into two parts so that the Media container 12 can be replaced in a simple manner. there is part 15 through a snap-in connection 44 with main part 14 connected. The media container 12 is also in this embodiment completely hidden in the housing 13. The main part of the Housing has the discharge opening 16, of which a dimensionally stable Riser pipe 17 leads to the pump element 18, which by means of 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 in the direction of the discharge opening 16 displaceable. When moving is on indirectly via the riser 17 the movable parts of the pump element 18 acted so that a Discharge stroke is generated. Serves to actuate the discharge device 11 the actuating element 24, which is pivotable about the pivot axis 19 is arranged. 5a, the actuating element 24 is in one Position held for example by locking, in which a direct Operation of the discharge device is not possible. So it's about around a storage or transport position in which is prevented that the discharge device is actuated unintentionally. By pivoting the actuator 24 in the position as it is shown in Fig. 5b, the operational readiness of the Discharge device 11 given. The actuating element 24 has one Handling surface 27 in which the user the operating force initiates. The distance between the place of application and the swivel axis 19 results in a lever arm. On the handling surface 27 opposite side of the actuating element 24 is a contour line 45 trained who the system of the actuator on the Deflection means 46 specifies. Due to the curvature of the contour line 45 a different distance of the contact point from the actuator 24 on the deflection means 46 to the pivot axis 19 of the Actuator and the distance of this contact point Pivot axis 47 of the deflection means 46 changed. This will make the Leverage ratios variable. This is also the contour line 48 of the deflecting means 46 shaped accordingly. By changing the Leverage ratios make it possible to have a different, depending on the actuation path changeable transmission ratio between the actuating force of the actuator and that on the media container generate acting force.

The deflection means 46 is itself in the embodiment shown Lever (cam) which can be pivoted about the pivot axis 47, educated. In addition to establishing a suitable gear ratio between actuator 24 and media container 12 serves the deflecting means 46 above all, so the direction of force to redirect that the main component of the force towards the Force vector H of the drawing, i.e. in the direction of the discharge opening 16 is introduced into the media container 12.

Nevertheless, it is possible to Guide media container axially in the housing 13. Furthermore the deflecting means 46 secures 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 is attached, but is relatively movable to this one Discharge stroke of the pump element due to axial displacement in the direction the direction vector H of the media container 12 is possible.

In Fig. 6, a discharge device is shown, which also by Actuation of actuators 24 a discharge of medium generated. In the closed with the cover 43 housing 13 is the Media container 12 arranged. Whose filling opening 21 is through the Pump element 18 closed. The pump element is used for generation a discharge stroke actuated via the actuating elements 24. each of these actuating elements acts on a toothed disc 50 which a tooth segment at least over part of its outer radius having. Both actuating element 24 and toothed disc 50 are each pivotable about an axis. Here are in the Housing 13 two actuators, each one Toothed washer 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 therefore also one Coupling between the two actuators is thereby achieved that this on a movable pump element, which by a axial stroke can cause a media discharge, intervene that is designed as a rack 49 with respect to both toothed disks. This embodiment allows the media container as The whole is fixed in the housing 13. The Power transmission between actuating means 24 and pump element takes place via the interlocking teeth of rack 49 and toothed discs 50. The deflection of 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 show in contrast to the previous figures Discharge devices 11, in which the actuating element 24 axially guided and is not pivotable.

Figures 7a and 7b show in the unactuated or actuated position a discharge device 11 with an actuating element 24 on the a slide 51 is designed to actuate the pump element 18. The slider 51 has a bevelled engagement edge 52 which a correspondingly formed flank 53 of the movable part of the Pump element acts. Engagement edge 52 and flank 53 slide in Actuation of the actuating element 24 to one another. Because that Actuating element 24 is guided axially 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 generated over the two flanks. A discharge stroke and thus a media discharge via the riser pipe 17 Discharge opening 16 can be created. At least one of them is Active elements engaging edge 52 and flank 53 as an inclined surface designed to redirect the operating force. The Slopes of the flanks to each other determine a translation and thus the connection between the actuation path and the required Operating 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 in turn part of the outer surface of the Discharge. The discharge opening 16 is in an application area 36 of the housing 13 arranged. To generate the linear Guiding the slide 51 serves a support beam 54, which is also for a Appropriate support of the slide 51 ensures that the Operating force without losses in an actuation of the pump element is implemented.

So that the best possible power transmission takes place and if possible Shear force components are balanced, it is possible, on both sides of the pump element and thus also on both sides of the riser tube 17 in each case to provide a slide 51, which then also on one edge 53 of the pump element 18 acts. Even with one In the embodiment, it is possible that between the actuating element 24 and housing 13 is an elastic molded part for a hermetic Connection ensures and a flat closed contour to the outside generated.

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

The discharge device 11 has a media container 12 which is in the housing 13 enclosing the media container 12 is arranged. The container 12 is in the region of its fill opening 21 closed by the pump element 18. This is the pump element 18 inserted into the fill opening 21 and is therein by the Fasteners 22 held. It is also possible that a good seal of the fill opening 21, a seal 23 is provided. The pump element 18 is a piston pump. there acts the rigidly formed riser tube 17, 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. It is Riser pipe 17 arranged coaxially to extend the piston pump. This ensures that the medium 32 is sucked in as completely as possible the pump element 18 can take place, the suction line 35 is provided, which leads at least almost to the bottom of the media container 12. The housing 13 can expediently all the elements except take up the container 12 to be filled and as a structural unit be prefabricated. The housing 13 is then on the media container 12 placed, the connection between the pump element 18 and Filling 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 Direction of its surface normal, corresponding to that in the drawing force arrow shown F. For this purpose, the actuating element is so stored that it is linearly movable in the housing. It will Actuator 24 formed in the manner of a button by Press is pressed. So that a good conclusion for the Actuator 24 required through opening 55 given , it is possible to provide a material layer 56 that is elastic deformable connection between the actuating element 24 and the housing 13 forms. The handling surface 27 of the actuating element 24 can also be made from this material layer be educated, which can also serve to be a pleasant one To produce a feeling of grip when actuating the actuating element 24.

The active element 28 of the actuating element 24 is a guide link 33 trained. A trained on the riser 17 Sliding block 34 is guided in the guide link 33. To be a good one Linear guide and a support of the forces in the housing 13 too enable, the support body 58 is provided, which is a guideway 57, in which the sliding block 34 is also guided. there the support body 58 can either directly with the housing 13 be connected or formed on the fastening means 22 or be integrally formed, the fastening means 22 at least is indirectly supported on the housing 13.

If the actuating element 24 in the direction of the force vector F actuated, it is shifted in a straight line, linearly. A possible one Material layer 56 would then have to deform elastically. The Active element 28 would also be shifted linearly. The linearity the movement is at least partially supported by the Sliding block 34 generated in the guideway 57. The one in the leadership setting 33 guided sliding block 34 is due to the shape of the backdrop track 33, e.g. is approximately circular segment shaped, in Direction down to the pump element 18, along the through the Stroke vector H given given direction. The on the active element 28 also transmitted and acting on the sliding block 34 Shear force component is supported in the guideway 57. In order to becomes the volume by actuating the actuating element 24 the pump chamber 59 of the pump element is reduced in that the Piston 60 is pushed down from the riser pipe 17. About the Volume reduction of the pump chamber 59 thus becomes a Media release generated. At the end of the actuation, the actuating element 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 Fig. 8a and 8b is. For this purpose, corresponding ones can also be found in the pump chamber 59 Operation counteracting return springs may be provided. alternative for this purpose, it would also be possible to use the energy store elsewhere To provide pump element 18. During the return movement the volume of the pump chamber 59 is increased again and thereby the suction line 35 medium sucked.
