The actuator (20) is configured such that it can be rotated relative to the attachment (30), and the supporting region (22) is therefore variable, in order to change the effective lever path for the actuation of the valve (2), for activating or deactivating the dispenser (1) or for varying the volume flow as product is dispensed.

Description

Pressure packing for viscous materials

The invention relates to a dispenser for dispensing a product from a container reservoir, in particular from a pressure vessel. With such dispensers, for example, viscous masses, in particular sealants and building materials such as silicone or acrylic-containing compounds are issued. In many cases, the output of these masses from a propellant contained and therefore pressurized container via the actuation of a Ventilmechanismusses.

Many such dispensers are known in the art. DE 600 15 798 T2 discloses such a dispenser with a pressurized product chamber in which the viscous material is contained. At the product chamber, a tilting valve is provided, to which a rotatable nozzle arrangement with a nozzle connects. A lever pivotally attached to the product chamber acts on the nozzle assembly upon application of force by the user to open the tilt valve to dispense the viscous material. The nozzle assembly can be rotated relative to its longitudinal axis and to the lever. In this case, a change of the bearing surface of the lever is achieved. This change optionally results in an open position of the dispenser where the force applied to the lever allows material to be dispensed through the valve. Or to a closed position, where no material issue is possible.

This system has many disadvantages. For example, only a choice between an open and a closed position of the nozzle assembly is possible. An adjustability of the product flow through the nozzle assembly is not provided. Another disadvantage is the complicated structure of the system and the associated high production costs. In addition, activation and deactivation of the system via a rotation of the nozzle assembly by 90 ° relative to the lever and the product chamber are possible. This is not easy to understand by a user, especially in a first-time application. Another major disadvantage is the lack of the possibility for one-handed operation of such a donor. The user must always guide the product chamber with one hand and rotate the nozzle assembly to activate the dispenser with the other hand so that full one-handed operation is excluded. Another disadvantage is that the nozzle belongs to the nozzle arrangement and thus to the triggering mechanism. Replacement of the nozzle or a cleaning is not provided. In addition, the user may injure himself by pinching the components such as the lever and the nozzle assembly, which are engaged with each other at work. Safe work can not be guaranteed with such a system.

The object of the invention is therefore to provide an improved dispenser, which eliminates the above-mentioned disadvantages and in particular ensures an improved adjustability of the product flow. This object is solved by the features of claim 1.

The advantageous embodiments of the invention are specified by the subclaims.

The basic idea of the invention is to use a dispenser for dispensing a product, comprising a container with a container axis, a valve, a nozzle connected to the valve via connecting means, an attachment, a lever with an engaging area for the user and an actuator a support portion providing an engagement point for the lever, the lever being pivotable about a fixed axis with respect to the attachment for actuation of the valve over the point of engagement, the actuator being rotatable relative to the lever, attachment and nozzle about the container axis in that the point of engagement for the lever is axially displaceable with respect to the container axis in order to change the effective lever travel for actuating the valve.

Preferably, a substantially cylindrical container is used. In this case, the valve is preferably arranged coaxially with the longitudinal axis of the cylindrical container on this and communicates with the cavity of the container. In this case, the attachment is provided on the same side of the container as the valve and so firmly connected to the container, that an axial displacement of the attachment with respect to the longitudinal axis of the container is impossible. The article has a storage possibility with a pivot axis about which the lever can be pivoted. Preferably, the lever is designed such that it has on one side of the attack area for the user and is pivotally mounted on the other side of the essay. The valve between the bearing of the lever and the attack area is arranged on the container. Through the actuator, the user can exercise by pivoting the lever force on the valve and open this for dispensing the product from the container. For this purpose, a support region is provided on the actuator, which provides points of attack for the lever for transmitting the force applied by the user. The valve preferably has a radially projecting collar or similar transmission means so that the force applied by the user via the lever and the actuator can be transmitted to the valve. The force applied by the user pushes the valve towards the container until it opens. In this way product mass can be dispensed from the container. The effective lever travel is the way by which the lever moves the valve. If the lever travel is sufficient, the valve opens and the material in the container is exhausted. Due to the rotatable mounting of the actuator preferably with respect to the container axis and a correspondingly shaped support region, the lever is provided with a rotation of the actuator modified attack points available. The support region is designed in such a way that the points of attack provided by the support region for the lever are displaced axially with respect to the container axis during a rotation of the actuator. Thus, by the twistability the actuator provided variable attack points over the heel area. Due to the fixed pivotal mounting of the lever on the attachment causes axial displacement of the attack points on the rotation of the actuator pivoting of the lever, whereby the effective lever travel for actuating the valve via the lever can be varied. The lever used is preferably designed angled. In this case, the range of attack of the lever in the resting state, in which no product output via the valve, preferably extend substantially parallel to the container axis. In this case, the lever and / or the attack area are preferably against the outer wall of the container. A force on the valve is preferably not exerted in this rest position. This design has the advantage that the user is provided a good leverage to be able to operate the donor with little effort. At the same time, little space is needed for the dispenser, which not only brings advantages in storage at the user, but also in the production and storage in the sales room. At the level of the valve above the container, the lever extends substantially orthogonal to the container axis angled to the attack area.

Preferably, the used for supporting area of the actuator is designed such that for the lever, a first rest position is provided, which corresponds to the above-described rest position of the lever. By the rotation of the actuator relative to the attachment and thus connected to the attachment lever, depending on the design of the support region of the actuator, the attack points of the lever can be axially offset with respect to the axis of the container in the direction of the latter. This offset of the point of attack of the lever causes a tilting or pivoting of the lever about the pivotable mounting on the attachment. Due to the preferably angled design of the lever, the angle between the attack region of the lever and container outer wall is increased in this pivoting of the lever. So can be changed by rotation of the actuator relative to the essay of the angle between attack area and container outer wall. Once the attack area is no longer applied, the user can exert force on it, which leads to a movement of the attack area in the direction of the outer wall of the container. Due to the angled design of the lever described above, this results in a force of the lever on the attack points of the actuator on the valve and to press the valve towards the container. The effective lever travel of the lever is the way the lever is able to push the valve towards the container. This is greater in the preferred design, the greater the angle between the attack area and the outer wall of the container.

This type of dispenser has the following advantages. The lever's adjustable attack points can disable the entire system by not providing enough effective lever travel to open the valve. An unintentional output of the product is avoided, for example. The above-described arrangement of Abstützmöglichkeit on the opposite side of the attack area allows the user ergonomic handling. As a rule, such a dispenser is operated with one hand. This encloses the Use the dispenser by hand in the force grip so that the container is enclosed by the thumb and fingers. This handle ensures safe guidance of the dispenser during application of the product. The output of the product is made either by the force of the fingers or the thumb on the attack area of the lever. The rotation of the actuator relative to the attachment, the user can very easily perform by means of one or more fingers of the same hand. This reveals a significant advantage of the device, the one-handed operation. The user is not only allowed to activate or deactivate the dispenser while guiding the dispenser in the power grip. Rather, it is also possible, for example, to regulate the volume flow during the dispensing of material via the adjustable points of attack via the actuator. Thus, for example, it is conceivable that the user grips the system as described above, activates the system via the actuator, exerts force on the attack area of the lever and thus applies the material. If the user needs an increased or reduced volume flow during the material application, he can regulate this by turning the actuator during the application process. An interruption of the job and an associated demolition of the product bead on the substrate are not necessary. Nevertheless, the possibility of one-hand operation ensures that the user can use his second hand for correction work or additional tools. It is also ensured that the user with his free hand, for example, on a ladder or scaffolding, as they are often found on construction sites, ensures that accidents at work can be avoided.

In order to simplify the rotation of the actuator when working with a dispenser according to the invention, it has proven to be advantageous to provide an adjusting means for rotating the actuator. This is preferably apparent from the overall arrangement and provides the user with a good attack opportunity. Thus, a secure rotatability of the actuator is guaranteed. For this purpose, supportive suitable recessed grips or anti-slip elements can be provided on the adjusting means.

A further advantage is the use of an attachment connected to the container, which surrounds the portion of the valve projecting from the container in regions with a side wall, wherein openings in the side wall for the lever and / or for actuating the actuator are provided. This side wall protects the valve and the moving parts and in particular the power transmission mechanism of the dispenser from external influences. In addition, the user is prevented from being injured as a result of pinching, as the force-transmitting component areas that communicate with each other during work, such as the lever and the actuator as well as the valve, are covered by the side wall of the attachment. The advantage here is the use of a cap, which can be connected to the essay. The cap provides further protection by covering the valve and transfer mechanism in addition to the side wall of the attachment. In this case, the cap preferably has an opening through which, for example, a nozzle for dispensing the material with can be connected to the valve, can be passed through. Preferably, the side wall surrounds the valve such that only one opening is provided, through which the lever protrudes. Thus, the user can exert force on the valve for dispensing the product from the container via the attack area of the lever protruding from the space enclosed by the side wall of the cap. Another embodiment provides an additional opening in the side wall for actuating the actuator. It is also conceivable a similar opening through which only one actuator provided on the actuating means to support the rotation protrudes. In this case, the opening is preferably provided in such a slot-shaped in the direction of rotation of the actuator in the side wall that a rotation is possible without any problem.

In order to facilitate the rotation of the actuator for the user, it is considered advantageous to provide one or more stops on the attachment, which limit the rotatability of the actuator. For example, the user can be provided with a starting point and an end point from which one or up to which a rotation of the actuator is possible. Another advantage is the use of locking points on the essay, which represent single rotary sections for the actuator. Here, for the user for predetermined and, for example, the material to be dispensed adapted attack points on the support region, which are achieved at a certain angle of rotation of the actuator relative to the essay, are provided. The user thus receives a dispenser that is easy to use since presets are provided by the detent points for possible product output quantities.

To ensure safe storage of the lever, it is considered advantageous to equip the article with supports on which the lever is pivotally mounted. The supports on the attachment are preferably substantially parallel to the container axis away from the container. Preferably, two opposing supports are provided, wherein the lever is mounted between the supports. In this case, the supports may have openings in which engage corresponding projections of the lever in order to ensure a pivotable mounting. Of course, a reverse design is possible in which the supports have the lever facing projections which engage in openings on the lever. Also, the use of a separate axis, which runs through holes through the supports and the lever conceivable.

Another advantage is the use of a lever which surrounds the valve, wherein pressure areas are integrally formed on the lever to support the lever at the points of attack on the support area. The molded and preferably projecting pressure areas allow a secure engagement of the lever at the points of attack and ensure a safe power transmission in the operation of the dispenser and in the output of the product. Preferably, the lever has an opening through which the valve is guided. The pressure ranges can be on both sides of the valve be formed opposite. This ensures good power transmission of the lever to the valve.

Another advantage of using a lever with molded pressure areas is such a structure of the dispenser that the attack line, which extends through the points of attack of the pressure ranges of the lever at the support area, substantially parallel to the axis of rotation of the lever. Such a structure prevents torsion of the lever upon application of force by the user in product dispensing. A dispenser with higher strength and thus for safer and more reliable work is thus provided. When the force is applied to actuate the valve, the part of the lever opposite the engagement area is supported via the rotatable mounting, for example on the supports of the attachment. The force essentially acts away from the container. Due to the parallel course of the attack line to the axis of rotation both bearing points, for example, both supports of the essay with the same force applied. If the Angrifflinie deviate, a bearing point of the lever would be more heavily loaded and destroyed, for example, due to material fatigue. This would result in irreparable damage and the donor's failure.

Another advantage is the use of an actuator having an opening through which the valve passes. The actuator is designed such that it surrounds the valve. In many cases, valves are used which have a hollow-cylindrical outlet channel. In this case, a circumferential collar protruding from the lateral surface is usually provided, via which force can be exerted on the valve for dispensing the product. By using an actuator with an opening through which the valve passes, good force transmission can be applied to a large area of the protruding collar.

Another advantage of using an actuator having an opening through which the valve passes is the equipment of the valve with connecting means for attaching, for example, a nozzle or other accessory to the valve for dispensing the product in the container, the opening of the valve Actuator is dimensioned such that the actuator is not engaged with the nozzle or the other auxiliary component. This has the advantage that a rotation of the actuator does not result in a rotation of the nozzle. Angled nozzles are used in many applications. If the user twisted the actuator engaged with the nozzle, the nozzle would twist to an unfavorable position for the user and the product application. By avoiding the engagement of the actuator and the nozzle, this is prevented. In addition, it is avoided that the actuator and the nozzle tilt, so that a rotation of the actuator or a replacement of the nozzle is impossible.

Another advantage is the use of an actuator with an opening, wherein with respect to the opening at least two opposite support areas are provided for the lever, which in Substantially part-circular arranged around the axis of rotation of the actuator. These support areas are preferably arranged in the vicinity of the opening through which the valve passes. This provides the lever with two opposing points of attack relative to the opening. A one-sided load of the actuator and consequently a unilateral force on the valve and a possible tilting or blocking of the components is prevented.

In the following the invention will be explained in more detail with reference to an embodiment shown in the drawings:

FIG. 5 shows a sectional side view of an assembly of the dispenser of FIG. 1 in the activation position for a normal product dispensing operation.

FIG. 6 shows a sectional side view of an assembly of the dispenser of FIG. 1 in the activation position for an increased product output.

Figures 1 -6 show a dispenser 1 according to the invention for dispensing a product from a cylindrical container 3 with a container axis 4. The container 3 is designed in the present case as a pressure vessel. As a material for this design, for example, metals, such as aluminum or tinplate are. Of course, other suitable materials can be used. With the container 3 is a valve 2 for dispensing the product located in the container 3 via a nozzle

7 provided. For this purpose, the nozzle 7 can be connected via connecting means 6 with the side facing away from the container 3 of the valve 2. The discharge opening of the nozzle 7 can by means of a cap

8 are covered, so that the nozzle 7 and the valve 2 is secured against contamination.

In the present embodiment, a tilting valve known from the prior art is used as the valve 2. Such a valve 2 is generally known in dispensers 1 and functions by tilting a hollow central spindle, which is elastically held by a rubber grommet on a mounting cup. The spindle is closed at its lower end by a sealing plate. When the spindle is tilted, the seal between the spout and the sealing plate is broken and the product in the container 3 can reach passages in the central spindle and then flow along the hollow spindle.

The valve 2 used here has proved particularly advantageous, which is not connected directly to the nozzle 7 used. The latter can be attached as an additional component via said connecting means 6, such as a screw or snap connection at the valve outlet, where the product is discharged. This division into two components has the advantage that different, the application case corresponding nozzles 7 can be used. Also, after use, the nozzle 7 can be removed for cleaning, so that the dispenser 1 can be used several times and not disposed of after a single use after curing of the product in the nozzle 7.

When the valve 2 is pressed or tilted in the direction of the container 3 when using the dispenser 1, it opens and the product in the container 3 can be dispensed. For this purpose, the dispenser 1 shown in Figure 1 on a lever 10, which communicates with the valve, not shown. The valve is covered by a cap 30 and protected from external influences. The attachment 30 is firmly connected to the container 3. The connection can be made, for example, by means of a snap connection or other types of connection known to those skilled in the art. Also conceivable is a connection via a bracket 9, which engages in a corresponding receptacle on the container 3. This would have the advantage that a spent container 3 is replaced with a new one, wherein the assembly for metering and dispensing of the product can be used. On top of 30 also not shown means, for example, protruding pins or spring elements can be provided which fix the lever 10 in its respective position to the container 3 or secure to a unwanted movement or slipping of the lever, for example, during transport, to avoid. This can be realized by applying, for example, a spring force. The cap 30 encloses the valve except for an opening from which the lever 10 protrudes and another, the first opposite opening completely. The latter is used to rotate an actuator 20. To facilitate the operation, a projecting actuating means 23 is provided on the actuator, which offers the user a good possibility of attack. The actuator 20 may be rotated about an axis, which corresponds to the longitudinal axis of the cylindrical container 3 in the present embodiment. About the rotation of the actuator 20, a change in the effective lever travel of the lever 10 is achieved for actuating the valve. In this way, via the actuator 20, a possibility is provided to activate the dispenser 1 via the variation of the effective lever travel of the lever 10, to deactivate or to vary the possible volume flow during the product dispensing. In order to facilitate the user's work with the dispenser 1, the part of the lever 10 protruding from the opening of the attachment 30 runs essentially parallel to the outer wall of the container 3. In this way, little space is required. The dispenser 1 shown is in rest position, so it has been deactivated via the actuator 20. In this position, the lever 10 is preferably against the outer wall of the container 3. In order not to be injured at work by trapping, the attachment 30 has a cover 33 which partially surrounds the region of the lever 10 projecting from the outer wall of the container 3. The lever 10 also has an engagement area 13 for the user, on which the user preferably exerts force on the lever 10 for product dispensing. This can also be equipped with recessed grips or slip-resistant inserts. To further protect the valve and the power transmission mechanism, the dispenser 1 is provided in addition to the attachment 30 with a cap 5, which is connected to the attachment 30.

FIG. 2 shows a sectional side view of the dispenser 1 from FIG. 1. The attachment 30 fixedly connected to the container 3 has supports 31 on which the lever 10 is pivotably mounted about an axis 11. The actuator 20 for varying the effective lever travel of the lever 10 can be rotated about the longitudinal axis 4 of the container, the axis of rotation 24. The actuator 20 has an opening through which the valve 2 extends. The opening is dimensioned such that the actuator 20 rests on a radially outwardly projecting collar of the valve 2 and can transmit power thereto. Of course, other power transmission options are conceivable instead of the collar. Like the actuator 20, the lever 10 has an opening through which the valve 2 extends. The lever 10 is arranged such that the actuator 20 is located between the lever 10 and the collar of the valve 2. To actuate the valve 2, the user exerts force on the attack area 13 of the lever 10 lying outside of the attachment 30 and pivots it about the axis 11. The lever 10 then presses on the actuator 20, which in turn acts on the collar of the valve 2 transfers to the latter. This force presses the valve 2 in the direction of the container 3 until the valve 2 opens and product can be dispensed from the container 3 via the valve 2. For finer dosage of the product, a nozzle 7 is provided, which over Connecting means 6 is connected to the valve 2 and protrudes from an opening of the cap 5 from the enclosed by the cap 5 and the cap 30 and protected from external influences space. The pivoting of the lever 10 about the axis 11 for actuating the valve 2 is limited by means of a stop. In the present embodiment, the outer wall of the container 3 is the stop for the angled portion of the lever 10 with the attack area 13. Of course, other stops for the lever 10 are conceivable. The lever can be pivoted so far around the axis 11 until the lever 10 rests against the outer wall of the container 3. In the present embodiment, the lever 10 is already on the outer wall of the container 3, so that a pivoting of the lever 10 for actuating the valve 2 is not possible. The dispenser 1 is thus in rest position and can not be triggered. To activate the dispenser 1, the lever 10 must be pivoted about the pivot axis 1 1, so that the distance between the lever 10 and the stop, the outer wall of the container 3 increases. For this purpose, the actuator 20 is provided. By rotation of the actuator 20 about the axis 24, the size of the force transmitting portion of the actuator 20 between lever 10 and collar of the valve 2 can be varied. By enlargement of this part by rotation of the actuator 20, the lever 10 is displaced in the region of the support on the actuator 20 in the opposite direction with respect to the container 3. This leads to a pivoting of the lever 10 about the pivot axis 11, wherein the angle between the angled portion of the lever 10 with the engagement portion 13 and the outer wall of the container 3 increases and thus the distance between the lever 10 and the stop, the outer wall of the container 3, enlarged. As a result, the user can exert force on the engagement area 13, thereby pivoting the lever 10 about the pivot axis 11 and thus exerting force on the valve 2 via the actuator 20 for dispensing the product. Accordingly, a change of the effective lever travel for actuating the valve 2 via the lever 10 is possible via the actuator 20. The user can by turning the actuator and an associated increase or decrease of the force transmitting portion of the actuator 20 between the lever 10 and collar of the valve 2, the system enable or disable or vary the possible flow rate in the product output.

The illustrated in Figure 3 perspective view of an assembly of the dispenser of Figure 1 shows the top 30 with the two supports 31. The supports 31 project from the base of the cap 30 in the opposite direction with respect to the container, not shown, substantially parallel to the valve 2 , Between the two supports one side of the lever 10 is arranged. The supports 31 have the lever 10 facing bearing points 32, which are designed as a bore, engage in the corresponding, substantially cylindrical projections 12 of the lever 10. Via the connection, which is formed by the bearing points 32 and the projections 12, the lever 10 can be pivoted about the axis 11 relative to the attachment 30. The lever 10 encloses the valve 2 and has at the storage of the attachment 30 opposite side of the angled portion with the attack area 13. This page protrudes out of an opening 36 from the top 30 and is thus easily accessible to the user. The attachment 30 has a side wall 34, which the valve 2 and the Power transmission mechanism for activating the valve 2 substantially encloses and thus protects against destruction and contamination. In addition to the opening 36 for the lever 10, the attachment 30 in the region of the side wall 34 has a further opening 38 for the actuator 20. Through this opening 38, the user can rotate the actuator 20 about the axis 24 to vary the effective lever travel. For this purpose, the actuator 23 is provided to the user, which offers a good possibility of attack. In order to limit the Verdrehweg of the actuator 20, 30 stops 35 are provided on the top 30 and on the side wall 34 of the essay. These stops 35 communicate with areas of the actuator 20 or the actuating means 23 and thus prevent a rotation of the actuator 20 beyond a preset angle. The actuator 20 has a valve opening 26 through which the valve 2 is guided. The valve 2 can be equipped via connecting means 6 with a nozzle, not shown. In this case, the opening 26 of the actuator 20 is dimensioned such that the nozzle is not in engagement with the actuator 20. Thus, it can be prevented that with a rotation of the actuator 20 about the axis 24, the nozzle is rotated with. The actuator 20 has in the region of the opening 26 two opposite support regions 22 for the lever 10. These support regions 22 are arranged substantially in the form of a partial circle around the axis of rotation 24 of the actuator 20 at this. The support portions 22 provide, depending on the rotation of the actuator 20, various points of attack 25 for the lever 10 for applying force via the actuator 20 to the valve 2 ready. The support areas 22 are provided on parking ramps 21. This has the consequence that the possible points of attack 25 for the lever 10 on the part-circular support portions 22 during the rotation of the actuator 20 depending on the height profile of the adjusting ramp 21 change. The change is a variation of the position of the points of attack 25 with respect to the longitudinal axis of the container. In other words, by a rotation of the actuator 20, the strength of the actuator 20 between the valve 2 and the effective range of the lever 10 along the control ramp 21 is changed. This change results in a pivoting of the lever 10 about the pivot axis 11 and thus to activate a variation of the effective lever travel of the lever 10 about the valve 2. In order to transmit the force introduced by the user via the lever 10 to the actuator 20 and thus to the valve 2, the lever 10 in the region of the opening through which the valve 2 extends, molded pressure areas 14 on. About these pressure ranges 14, the lever 10 is supported at the points of attack 25 at the support areas 22. In this case, the pressure regions 14 are designed such that the engagement line 15, which extends through the respective contact points 25 of the support region communicating with the pressure regions 14, runs essentially parallel to the axis of rotation 11 of the lever 10. Of course, other embodiments are conceivable in addition to the design shown. In particular, it is conceivable to divide the actuator 20 in several components. Thus, in another embodiment, for example, an assembly as an actuator 20 is conceivable, wherein a component of the assembly includes the support portion 22 and another, communicating with the first component provides a possibility of twisting the first for the user. This separation would in particular have the advantage that when the actuator 20 is offset due to the action of force by the user the valve 2 would not move the possibility of rotation of the actuator 20 in the direction of the container.

Figures 4, 5 and 6 show sectional side views of the dispenser 1, wherein has been omitted to increase clarity on the representation of some components, such as the essay. Here the dispenser 1 is shown in rest position, in the activation position and in the activation position for increased product output.

FIG. 4 shows the dispenser 1 in the rest position. The region of the lever 10 with the engagement region 13 abuts in this position on the outer wall of the container 3, so that the lever 10 is not pivoted about the axis 11 and thus no force can be exerted on the valve 2 via the lever 10. There is no effective lever travel for operating the valve 2 in this position. For this purpose, the actuator 20 has been rotated about the adjusting means 23 about the axis 24 so that the support portion 22 is on the Stellrampe 21 in such a position that the pressure range 14 of the lever 10 no attack point is provided.

FIG. 5 shows the dispenser 1 in the activation position. For this purpose, the actuator 20 has been rotated by means of the adjusting means 23 about the axis 24 such that the lever 10, an attack point 25 is provided on the support portion 22 on the Stellrampe 21. Due to the setting ramp 21, the lever 10 has been displaced in the direction of the product output side of the valve 2 during the rotation of the actuator 20 along the support region 22. This results in a pivotal movement of the lever 10 about the axis 11, thereby increasing the angle between the region of the lever 10 with the engagement region 13 and the outer wall of the container 3. The user can now exert force on the attack area 13 in the direction of the container 3 and pivot the lever 10 about the axis 11. As a result, the force introduced by the user would be transmitted via the pressure region 14 of the lever 10 to the point of application 25 and thus to the valve 2, which would result in an offset of the valve 2 in the direction of the container 3. In the activation position of the dispenser 1, sufficiently effective lever travel is provided for actuating the product delivery valve 2.

Figure 6 shows the dispenser 1 in the activation position for increased product output. For this purpose, the actuator 20 has been further rotated by means of the adjusting means 23 about the axis 24 in comparison to the position of the actuator 20 of the dispenser 1 in Figure 5. The lever 10 has been further displaced during the rotation of the actuator 20 along the support region 22 in the direction of the product output side of the valve 2. This re-pivotal movement of the lever 10 about the axis 11 leads to a larger angle between the region of the lever 10 with the attack area 13 and the outer wall of the container 3. The user can exercise in this case force on the attack area 13 in the direction of container 3 and pivot the lever 10 about the axis 11. As a result, the force introduced by the user via the pressure region 14 of the lever 10 on the point of attack 25 and thus on the Valve 2 are transmitted, which would have an offset of the valve 2 in the direction of container 3 result. In the activating position of the dispenser 1, not only is sufficiently effective lever travel provided for operating the product delivery valve 2. Rather, the valve 2 can be pressed in the direction of the container, that the output of the product with an increased volume flow is possible.

In addition to the examples shown, of course, intermediate steps in the rotation of the actuator 20 are possible, so that the user can vary the effective lever travel continuously. In addition, the use of a Stellrampe 21 is possible, which divides the support portion 22 in different stages. The user would thus be provided with a dispenser 1 which has predefined, preferably predetermined, product and / or nozzle geometry adjusted flow rates for product dispensing. These stages are available for certain effective lever paths of the lever 10 for actuating the valve 2 via the lever 10. It is conceivable here, for example, the use of two stages for a rest position and an activation position. This is particularly useful for laymen and beginners who would be overwhelmed with a regulation of the flow rate of the product. By incorporating additional levels for advanced and professionals, such as craftsmen, additional effective lever paths can be provided so that the flow rate can be adapted to specific needs. Also, the adjustment ramps 21 can be designed asymmetrically. This may mean, for example, that the support regions 22 of both adjustment ramps 21 are divided into steps, but the steps of the support region 22 of an adjustment ramp 21 are phased, the steps of the support region 22 of the second adjustment ramp 21 having sharp edges. By using an actuator 20 with such adjustment ramps 21, a good sliding of the lever 10 over the individual phased stages of a support region 22 can be made possible. The sharp-edged steps of the other support area 22 allow a secure fit of the lever 10 for a safe application of force via the lever 10 to the valve. 2
