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 valve assembly and the complex Assembling- and filling processes 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.

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 dispensers for dispensing adhesives and sealants from a container reservoir with a valve for metered product delivery, a lever for actuating the valve, wherein the lever is provided on one side of the valve with an attack area and on the other Side of the valve to use a bearing area for supporting the lever on a counter-bearing, wherein the valve is actuated by a force on the lever in the direction of reservoir reservoir and wherein the lever is pivotally mounted about a pivot axis about the valve and wherein the anvil is designed to be adjustable, to change the effective lever travel of the lever for actuating the valve via the lever.

In a first basic variant, the lever is preferably tiltable or pivotable about the valve so that the attack area of the lever for the application by the user is located on one side of the valve. On the other side of the valve, the lever has a bearing portion with which the lever can be supported in use on the adjustable counter-bearing in order to change the effective lever travel of the lever. The location of the attack area and abutment is explained by the valve position with respect to the longitudinal axis of a cylindrical vessel. The valve is preferably arranged coaxially with the longitudinal axis of the cylindrical container reservoir on this. The one side of the valve, on which the attack region of the lever is arranged, extends from the valve radially outward with respect to the longitudinal axis of the container reservoir. The other side of the valve having the adjustable abutment extends radially outwardly from the valve with respect to the longitudinal axis of the reservoir reservoir. The lever is designed in such a way that the bearing area of the lever is pressed against the counter bearing when the user applies force to the area of engagement of the lever in the direction of the reservoir reservoir. By this support of the lever on the abutment is exerted by the force of the user, a force on the valve in the direction of the reservoir reservoir. The force pushes the valve towards the reservoir reservoir until it opens so that product mass can be dispensed from the reservoir reservoir. 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 reservoir is discharged. The lever used is preferably designed angled. In this case, the attack region of the lever in the idle state, in which no product output via the valve, preferably extend substantially parallel to the container reservoir axis. In this case, the lever and / or the attack area are preferably on the outer wall of the container reservoir. 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 reservoir, the lever extends substantially orthogonal to the tank reservoir axis angled to the attack area.

Preferably, the adjustable counter-bearing used is designed such that it has a first rest position, which corresponds to the above-described rest position of the lever. The storage area of the lever is preferably already in this position on the counter bearing. Due to the adjustment of the anvil, this can be displaced from a rest position such that it is offset substantially axially with respect to the axis of the container reservoir in the direction of the latter. The preferably already in the rest position of the thrust bearing bearing area of the lever is pressed by this adjustment and the associated offset of the thrust bearing towards the container. This depression of the bearing area of the lever causes the lever to tilt or pivot about the valve. Due to the preferably angled design of the lever, the angle between the attack area of the lever and container reservoir outer wall is increased in this tilting of the lever. Thus, the angle between the attack area and container reservoir outer wall can be changed by the adjustable counter bearing. Once the attack area is no longer applied, the user can apply force to it, which leads to a movement of the attack area in the direction of the outer wall of the container. Due to the above-described angled design of the lever, this results in a force acting on the valve and a pressure of the valve in the direction of the reservoir reservoir. In this case, the effective lever travel of the lever is the way that the lever is able to push the valve in the direction of the container reservoir. This is the larger in the preferred design, the greater the angle between the attack area and the outer wall of the container reservoir.

Accordingly, a variation of the effective lever travel of the lever is possible by the adjustment of the anvil. From a certain effective lever travel, the valve can be moved sufficiently to open and release product mass. Consequently, an activation of the system can be made, among other things, by means of the adjustment of the anvil, from which there is sufficient effective lever travel available to open the valve. By further varying the anvil, the lever travel can be further increased, resulting in a possibility of pushing the valve beyond the point of activation. In this case, the valve is preferably designed such that, in order to provide an increased product flow, a larger opening geometry is provided for dispensing the product located in the container reservoir. Thus, the adjustment of the anvil makes it possible to regulate the possible product flow. Preferably, the counter-bearing can be designed so that at least as much effective lever travel is available when a force is applied to the engagement region of the lever that the valve can be triggered.

This first basic variant has the following advantages. The adjustable counter bearing allows the entire system to be disabled by not providing enough effective lever travel to open the valve. An unintentional output of the product, for example, is avoided. The above-described arrangement of the anvil on the opposite side of the attack area allows the user an ergonomic handling. As a rule, such a dispenser is operated with one hand. For this purpose, the user encloses the dispenser by hand in the power grip, so that the container reservoir is enclosed by the thumb and fingers. This handle ensures safe guidance of the dispenser during application of the product. The product is released by the force of the fingers on the attack area of the lever. The adjustable abutment on the opposite side of the attack area can be adjusted in this donor guide, for example, via suitable means by the thumb of the user. In this position, the user can adjust the opposing bearing located opposite the attack area by means of the thumb and at the same time leave the fingers on the attack area. 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 counter bearing. For example, it is conceivable that the user grips the system as described above, activates the system via the anvil, exerts force on the attack area of the lever and thus applies the material. If the user requires an increased or reduced volume flow during the material application, he can regulate this by adjusting the anvil during the application process. An interruption of the job and an associated demolition of the product bead on the substrate is 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. Of course, the design described above is just one of many solutions to provide an adjustable thrust bearing for adjusting and varying the effective lever travel. It is also conceivable a second basic solution for the realization of an adjustable counter bearing. For example, a generic dispenser having a lever for actuating the valve, wherein the valve is actuated by a force on the lever opposite to the container reservoir and wherein the lever is equipped on one side of the valve with an attack area and between the attack area and the valve a Has storage area for supporting the lever on an adjustable abutment. The lever is pivotally mounted about the anvil. Again, you can change the effective lever travel of the lever for actuating the valve via the lever and achieve activation, deactivation and / or variation of the volume flow of the product to be dispensed by the adjustable counter bearing. In this solution, preferably no pressure or tilt valve is used, in which the opening of the valve this has to be pressed or tilted in the direction of the container reservoir. Preference is given here to the drafting valves known to the person skilled in the art, which are pulled away from the container reservoir for opening. In this design of the dispenser, the lever is arranged tiltable or pivotable about the anvil. By applying pressure to the attack area, the valve is pulled away from the reservoir reservoir. By way of the adjustable counter bearing, in turn, the effective lever travel for pulling the valve can be varied, so that activation, deactivation and / or variation of the volume flow is made possible. Again, a one-hand operation is possible. Preference is given to suitable means for ergonomic operation of the anvil are used.

It has proven particularly advantageous to use an adjustable counter bearing which has a plurality of bearing stages. These bearing stages correspond to predetermined effective lever travel of the lever for actuating the valve via the lever. It is conceivable here, for example, the use of an abutment with different, preferably predetermined and adapted to the product and / or the nozzle geometry bearing stages. For example, the use of an abutment would be possible, with only two bearing stages are provided 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. The other variant for advanced and professionals, such as crafts, additionally includes an adjustment of the anvil such or additional predetermined storage levels of the anvil that the flow can be adapted to the specific needs. These bearing stages could for example be provided with the locking mechanisms known to the person skilled in the art or have suitable receptacles for the bearing area of the lever. Conceivable, in particular, would be an equipment with counter bearings such that the Dispenser is disabled in rest position and not sufficiently effective lever travel is available to trigger the valve. The subsequent adjustment of the anvil could provide activation of the system where the user can apply a small amount of material by applying force to the attack area. Further adjustment of the anvil would result in a predefined increase in the volume flow and thus in the application of material when force is applied by the user. The user would thus be provided with a tool which is easy to operate and in which a safe dosage is possible. This equipment variant of the donor is a useful option, especially for first-time users.

Another advantage is the equipment of the dispenser with a continuously adjustable counter bearing. This stepless adjustability of the counter bearing provides a continuous change of the effective lever travel of the lever for actuating the valve via the lever. This is particularly useful for reducing or increasing the volume flow and thus the material application during use. If, for example, the user notices during the job that he suddenly requires a higher volume flow, he can set the desired flow rate by means of the stepless adjustment of the anvil and thereby a continuous adjustment of the effective lever travel according to the required amount. This is particularly useful when grouting in the sanitary area. The joints do not always have the same width everywhere, so it may seem appropriate to regulate the volume flow and thus the material order.

Another advantage is the use of a bearing portion of the lever, which corresponds to the shape of the anvil. Thus, a secure hold of the storage area can be ensured at the abutment in order to avoid unintentional activation, deactivation and / or change of the flow rate. Preferably, the bearing portion is formed as a substantially round protruding shape of the lever, which fits into a corresponding recess of the anvil. It is also conceivable embodiment such that the abutment includes multiple scenes for receiving the storage area of the lever. By this example, depressions are to be understood, in which engages the storage area of the lever which is supported on the abutment. Of course, other forms are conceivable that ensure a secure engagement for the lever. For example, predetermined settings for the activation and / or deactivation of the system are provided at which the storage area engages in the provided for the respective position backdrop of the thrust bearing. Another possibility would be, for example, the provision of an abutment, which provides several levels as the attack surface, wherein one level each provides a step of the adjustable abutment on which the lever is supported over a larger area. In this way, the user over The force applied to the attack area distributed over a larger area and the counter bearing is not punctually loaded, which, for example, material fatigue can be excluded.

Another advantage is the use of a return spring, which exerts a force on the lever. Preferably, the return spring is connected to the container reservoir and acts on the lever such that the attack region of the lever is urged toward the rest position. Preferably, the return spring is biased and already acts force on the lever when the lever is already in the rest position. Preferably, a plastic component is used as the return spring, which is fixedly connected to the container reservoir, i. is not axially displaceable with respect to the container reservoir. The plastic component is bent by the lever. The plastic component is preferably elastic, so that it pushes back into its original position and thus exerts a force on the lever. Of course, other return springs, all springs known in the art, such as elastic, helical or spiral curved, stretched or sheet-shaped machine elements are conceivable.

In the first basic variant described above, the return spring preferably acts on the bearing area such that it is pressed against the counter bearing. This has the advantage that the lever is held in position on the anvil and does not wobble when the dispenser is not in use. In addition, the return spring facilitates in this way the operation. It presses the bearing area against the counter bearing so that the force exerted by the user is transmitted directly to the valve. There is no game must be overcome because, for example, the storage area is not applied to the anvil. Further, the attack area of the lever is urged when not in use and deactivation of the system towards the container outer wall, so that the dispenser requires a small footprint.

Also in the second basic variant described above, the use of such a return spring is advantageous. Again, the return spring is preferably arranged such that it urges the attack area in the direction of the container outer wall. This ensures play-free working with the lever and enables storage in the tightest of spaces.

Another advantage is the use of an actuating means on which the abutment is provided. On the basis of this actuating means, the counter bearing can be adjusted to support the lever and thus the effective lever travel of the lever can be varied. As adjusting any desired configurations are conceivable. The adjusting means may in particular be mounted rotatably or displaceably on the dispenser in order to adjust the abutment. Particularly advantageous is an adjusting agent has been found, which gives the user a sufficiently large attack opportunity for a provides secure adjustment. The use of means in the operating range of the user for the safe guidance of the actuating means is advantageous. These agents give the user good grip on the actuating range of the actuating means. In this case, the adjusting means may in particular be equipped with a non-slip contour, such as recesses or elevations directed transversely to the movement direction. Also conceivable are rubber or silicone inserts, which provide the user with a secure and / or comfortable grip on the adjusting means. Furthermore, the adjusting means may have an ergonomic shape in the region of the gripping surface of the user, which, for example, the thumb, which is particularly suitable for an adjustment of the anvil at work as described above, provides a good gripping surface. The latter design has proven to be particularly advantageous. With a recess in the adjusting means as an ergonomic grip surface for the thumb, it can be additionally equipped with a tamper-evident closure before the first use. Thus, for example, a plastic flag is conceivable, which is for example connected to the nozzle or another component which is designed such that it protrudes into the recess of the actuating means. The user can only use the actuator and thus activate the dispenser when he removes this plastic flag. This makes it immediately obvious to every user whether a dispenser was already in use or still in its original packaging and unused. Be particularly advantageous in a dispenser of the first variant, the following design of the donor has been found. The dispenser has a cover above the container reservoir, which protects the transmission mechanism between lever and valve against external influences. In addition to the product dispensing nozzle protrude only the attack area of the lever and the actuating means above the container reservoir out of the cover. In this case, the adjusting means preferably has a recess which provides a secure possibility of attack for the thumb of the user. In order to adjust the counter bearing the adjusting means is rotatably mounted about an axis. This design allows a good one-handed guidance of the donor and easy adjustability of the anvil by means of the thumb.

Particularly advantageous is the use of an eccentrically mounted actuating means has proven. In this case, the adjusting means is arranged, for example, above the container reservoir in the vicinity of the valve. The use of the following design has proved to be particularly advantageous. In an axial position of the valve with respect to a substantially cylindrical container reservoir, the adjusting means in the height of the valve can be arranged radially outwardly with respect to the axis of the cylindrical container reservoir. The adjusting means is rotatably mounted, wherein the axis of rotation of the actuating means is arranged substantially orthogonal but radially offset from the longitudinal axis of the container reservoir, as well as parallel and spaced from the pivot axis of the lever. The lever is arranged in this case pivotable about the valve, that the pivot axis of the lever is substantially orthogonal to the longitudinal axis of the container reservoir. The Adjusting means provides the counter bearing for the lever ready. Due to the eccentric bearing, that is, the bearing deviating from the center or the symmetry of the actuating means, different positions of the thrust bearing or different bearing stages of the thrust bearing can be provided for the bearing area of the lever by rotation of the actuating means. By the arrangement described above, the different positions of the thrust bearing cause a pivoting of the lever about its pivot axis, whereby the effective lever travel of the lever can be varied.

Another advantage when using an adjusting means for adjusting the counter-bearing is the use of an actuating means holder for the stationary storage of the actuating means in relation to the container reservoir. This means at least one fixation of the anvil in the axial direction with respect to the container reservoir. This actuating means holder can preferably be integrated into an attachment for the container reservoir. This attachment may also include a cover for areas of the valve, the side cheeks of the attack area of the lever and / or the power transmission mechanism between lever and valve. This cover has the advantage that on the one hand, the components are protected from external influences such as dirt and dust. On the other hand injuries are avoided, for example, by pinching the user to moving parts, which increases the safety. In addition, it is possible to make the attachment rotatable relative to the container reservoir around the valve with actuator holder. This is particularly useful when the outer surface of the container reservoir is provided with instructions on the use of the dispenser and, for example, parts of the lever obscure parts of the instructions. In this case, the user could turn the adjusting means holder relative to the container reservoir to the desired position. As described above, as a result of the rotation of the actuating means holder, the components arranged there are also lever, adjusting means holder and adjusting means rotated, so that the user can immediately start with the application of material in the position set by him. The stationary mounting of the actuating means in relation to the container reservoir would in this case be understood as meaning a lack of axial displaceability of the actuating means holder in relation to the axis of the container reservoir.

Another advantage is the use of a valve which has a collar, again with the lever having an effective area which can be engaged with the collar of the valve to activate the valve. The collar is preferably arranged substantially around the outer periphery of the valve above the container reservoir. The corresponding counterpart, the effective range of the lever, may have a corresponding shape to the collar of the valve. In this way, a secure engagement of effective range and collar can be ensured. For example, the lever is pivotally mounted around the valve as described above. It is advantageous to design the effective range such that in each Position of the pivoting range of the lever around the valve ensures a secure engagement with the collar. This is conceivable, in particular, by means of an outer contour of the collar of the valve which tapers in the direction of the discharge end of the valve and in the direction of the lever, the effective area of the lever having an oppositely corresponding outer contour. This shape allows even when changing position of the components to each other by pivoting the lever effective engagement. Of course, other shapes, in particular rounded, chamfered contours in the effective range and / or the collar are conceivable.

Another advantage is the use of a lever, which has an opening through which the valve passes. In this case, the opening of the lever is preferably oval or elliptical, wherein in this embodiment, the shortest diameter preferably extends transversely to the lever. This size is selected according to the valve used. Preferably, the shortest diameter of the opening, which is transverse to the lever, is just large enough to allow the lever to be mounted on the valve and that the lever has sufficient clearance to pivot about the valve. The longest diameter of the opening extends in the direction of the lever. This ensures that the edges of the opening do not collide with the outer wall of the valve when the lever is pivoted about the valve when the effective lever travel is changed. Of course, other forms are conceivable. The main advantage of an arbitrarily shaped opening through which the valve runs is the increased stability of the lever when used in contrast to levers, which are guided past the valve on one side.

Another advantage of using a lever with an opening for the valve is the equipment of the opening at least with a one-sided chamfer. In this case, the edges of the opening portion of the lever, which is applied in the application force on the valve or on the above-mentioned collar of the valve, bevelled. Preferably, the chamfer has an angle of 45 °. Of course, other appropriate angles are possible. Of course, bevels are also conceivable. Preferably, however, chamfers are used whose shape corresponds to the bearing surface of the valve, such as the above-mentioned collar. With such a solution in conjunction with a matching contact surface of the valve, the force transmission unit is provided with the largest possible area for the actuation of the valve from the contact edge of the opening of the lever and the bearing surface of the valve. Thus, one can provide a stable and durable dispenser that is safe to handle even with a lot of power.

Particularly advantageous in the use of an opening in the lever through which the valve extends is a design of the opening such that the edges of the opening at least partially provide the above-mentioned effective range of the lever for the collar of the valve. It can this effective range can be designed as desired. Of course, the already treated bevel or rounding of the edge is possible. Preferably, a rounded, protruding contour of the edges of the opening is such that the lever on this protruding contour along the curve around the valve is pivotable. Thus, in any position of the lever, that is guaranteed at any desired setting of the effective lever travel a safe power transmission from the lever to the valve. At the same time, the protruding curve ensures that the lever is easy to pivot around the valve.

In the following the invention will be explained in more detail with reference to two exemplary embodiments illustrated in the drawings:

FIG. 1 shows a sectional side view of a first variant in the rest position.

FIG. 2 shows a sectional side view of the dispenser according to the invention from FIG. 1 in the activation position.

FIG. 3 shows a sectional side view of the dispenser according to the invention from FIG. 1 in position for an increased product output.

FIG. 4 shows a sectional side view of the dispenser according to the invention from FIG. 1 during product dispensing.

FIG. 4 shows a sectioned side view of a second variant in the rest position.

Figures 1-4 show a first embodiment of a dispenser 1 according to the invention for dispensing a product outside a cylindrical container reservoir 18 with a container reservoir axis 19. The container reservoir 18 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 reservoir 18, a valve 4 for dispensing the product via a nozzle 23 is provided. For this purpose, the nozzle 23 can be connected via latching means 24 to the side of the valve 4 facing away from the reservoir 18. The discharge opening of the nozzle 23 can be covered by a closure 26, so that the nozzle 23 is secured against contamination.

In the present embodiment, a tilting valve known from the prior art is used as the valve 4. Such a valve 4 is generally known in dispensers 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 material in the reservoir reservoir 18 can reach passages in the central spindle and then flow along the hollow spindle.

Particularly advantageous is the valve 4 used here, which is not directly connected to the nozzle 23 used for use. This is as an additional component via said locking means 24 or other suitable connection techniques, such as screw or snap connections at the valve outlet, where the product is discharged, are attached. This division into two components has the advantage that different, the application case corresponding nozzles 23 can be used. Also, after use, the nozzle 23 may be removed for cleaning so that the dispenser 1 may be used several times and not disposed of after a single use after curing of the product in the nozzle 23.

When the valve 4 is pressed or tilted in the direction of the container reservoir 18 when using the dispenser 1, it opens and the product located in the container reservoir 18 can be dispensed. For this purpose, the dispenser 1 has a lever 2 with an opening 9, through which the valve 4 extends. The lever 2 is pivotally mounted about the rotation axis 8 and the valve. The lever 2 has on one side an attack area 3, on which the user can exert force on the lever 2 for actuating the valve 4. On the other side, the lever 2 has a bearing area 5, with which the lever 2 can be supported on an abutment 6. The abutment 6 is provided on an adjusting means 13 and includes a plurality of bearing stages 7, 7 ', 7 ". Of course, an eccentrically designed adjusting means 13 is also conceivable, for example. which provides a stepless adjustability of the anvil 6 for the storage area 5. The adjusting means 13 is provided on a actuating means holder 15 which is fixedly connected via a carrier plate 20 with the container reservoir 18. The adjusting means 13 is rotatably mounted about an actuating means rotational axis 14 in such a manner that a plurality of bearing stages 7, 7 ', 7 "can be provided to the bearing area 5 of the lever 2. The bearing area 5 of the lever 2 is shaped in such a way that it can move into the bearing area 5 of the lever 2 Bearing levels 7, 7 ', 7 "of the thrust bearing 6 inserts and finds secure hold. In the present exemplary embodiment, the bearing area 5 of the lever 2 is formed as an outwardly curved curve, wherein the bearing stages 7, 7 ', 7 "of the counter bearing 6 have a corresponding shape The lever 2 presses in the direction of the abutment 6 in the region of the bearing area 5. The valve 4 projecting above the carrier plate 20 has a peripheral collar 11 on which a bearing ring 12 is arranged above the carrier plate 20. This bearing ring 12 is loosely connected to the valve 4 In the area of the opening 9, the lever 2 has an effective area 10 on the side of the side cheeks facing the container reservoir 18. This effective area 10 is designed as a protruding curvature that engages with the bearing ring 12 of the valve 4. By applying force to the area of attack 3 of the lever 2 is by supporting the bearing portion 5 on the thrust bearing 6 a force applied over the active region 10 of the lever 2 on the bearing ring 12 of the valve 4, whereby the valve 4 is pushed towards the container or reservoir 18 is tilted.

The present embodiment shows the dispenser 1 is rest position, that is, the abutment 6 is designed such that the lever 2 can not be pivoted about the axis of rotation 8, since the attack area 3 abuts against the outer wall of the container reservoir 18. There is thus no force on the valve 4 and thus no product issue possible. To protect against external influences, the dispenser 1 has a diaphragm 22, and a cap 21. The aperture 22 serves as a recording of the attack area 3 of the lever 2 directly on the container reservoir 18, so that the attack area 3 of the lever 2 is not directly on the outer wall of the Container reservoir 18 is present. This has the advantage that no unintentional opening of the valve 4 by exerting force on the attack area 3 of the lever 2 is possible. The adjusting means 13 has a recess 16 which provides a secure point of attack for the user. In addition, a fuse 25 is provided as a proof of originality, which is connected to the nozzle 23 and engages in the recess 16 of the actuating means 13. Only after removal of the fuse 25 from the recess 16, a user can rotate the adjusting means 13 about the actuating means rotational axis 14, so that the abutment 6 can be adjusted for the bearing portion 5 of the lever 2 such that the lever 2 is pivoted about the axis of rotation 8 in order to be able to dispense product mass from the container reservoir 18. FIG. 2 shows the dispenser 1 from FIG. 1 ready for use. In this case, the adjusting means 13 is rotated about the actuating means rotational axis 14 such that the counter bearing 6 has been changed for the bearing region 5 of the lever 2. As a new counter-bearing 6 for the storage area 5, a second storage stage T has been provided by which the storage area 5 is pressed in the direction of container reservoir 18, so that the lever 2 is pivoted about the pivot axis 8, which increases the angle between the attack area 3 of the lever 2 and outer wall of the container reservoir 18 has resulted. In this position of the attack area 3 of the lever 2, the user has the opportunity to press the attack area 3 in the direction of the reservoir reservoir 18. As a result, 2 force would be exerted on the bearing ring 12 and thus on the valve 4 by the storage of the storage area 5 and the storage stage T of the abutment 6 on the effective range 10 of the lever. As a result, the valve 4 would be tilted or pivoted in the direction of the container reservoir 18. This leads to an output of the product via the valve 4 from the container reservoir 18th

By adjusting the abutment or by providing a second storage level T for the storage area 2 can thus change the effective lever travel of the lever 2. The effective lever travel of the lever 2 in the present invention is the way that the lever 2 is able to move the valve 4 in the direction of the reservoir reservoir 18.

3 shows the previously described dispenser 1, wherein a further storage stage 7 "of the abutment 6 for the storage area 5 of the lever 2 is provided by rotation of the setting means 13 about the rotation axis 14. This results in a further enlargement of the angle between the attack area 3 and outer wall of the Container reservoir 18. The user is thus provided with a larger lever travel when actuating the engagement region 3 of the lever 2. The bearing of the bearing region 5 at the bearing stage 7 exerts a force on the valve 4, resulting in a displacement of the valve 4 in the direction of reservoir reservoir 18 and to an output of the product via the valve 4 from the reservoir reservoir 18 with increased volume flow.

Figure 4 shows the dispenser 1 of Figure 3 at the moment of force by the user on the attack area 3 of the lever 2. The attack area 3 is in the present case again on the outer wall of the container reservoir 18 at. Due to the change in angle between the attack area 3 and the outer wall of the container reservoir 18 and the supporting of the storage area 5 of the lever 2 at the storage stage 7 "of the abutment 6, the valve 4 was pressed in the direction of the reservoir 18, so that product mass from an opening communicating with the container reservoir 18 27th of the valve 4 can be output. FIG. 5 shows a further embodiment of a dispenser 101 for dispensing a product outside a cylindrical container reservoir 118. In the present case, the container reservoir 118 is likewise configured as a pressure container. The container reservoir 118 is provided with a valve 104 for dispensing the product via a nozzle 123. For this purpose, the nozzle 123 is connected via suitable latching means with the container reservoir 118 facing away from the side of the valve 104. In particular, snap or screw connections can be used here. The dispensing opening of the nozzle 123 is covered by a closure 126 when the dispenser 101 is not in use, so that the nozzle 123 is protected from contamination. The valve 104 is designed in the present case as a pull valve. When valve 104 is pulled away from reservoir reservoir 118, it opens and the product in reservoir reservoir 118 is exhausted via valve 104 and via nozzle 123. For this purpose, the dispenser 101 has a lever 102 with an opening 109 through which the valve 104 extends. The lever 102 is pivotally mounted in the dispenser 101. Of course, suitable biasing or restoring elements may be provided which urge the lever 102 to a rest position. The rest position is that position of the lever 102 in which no force is exerted on the valve 104 and / or in which the engagement region 103 of the lever 102 rests against the outer wall of the container reservoir 1 18. The lever 102 has on one side an engagement portion 103, on which the user can exert force on the lever 102 for actuating the valve 104. Between the engagement region 103 and the valve 104, the lever 102 has a bearing region 105 with which the lever 102 is supported on an abutment 106. The counter-bearing 106 is provided on an adjusting means 113. The adjusting means 1 13 is designed as an eccentrically shaped element which is rotatable about a rotation axis 114. For rotation of the actuating means 113 are appropriate, not shown means, such as a lever or a thumbwheel provided, which are arranged such that the user can turn the adjusting means 113 during operation of the dispenser 101 easily. The adjusting means 1 13 is further provided on a Stellmittelhalter 115 which is fixedly connected via a carrier plate 120 with the container reservoir 118. By the rotation of the adjusting means 113 about the actuating means rotational axis 114, the counter bearing 106 is adjusted for the bearing area 105 of the lever 102. Of course, predefined bearing stages for a predefined volume flow for material dispensing can also be provided on the adjusting means 113 as an abutment 106. However, the present embodiment shows a stepless adjustability of the anvil 106. Of course, storage area 105 and abutment and / or the storage stages may have corresponding shapes, so that a secure hold of the storage area 105 on the anvil 106 and / or at the storage levels of the storage area 106 are ensured can.

The protruding from the support plate 120 valve 104, which extends through the opening 109 of the lever 102, above the opening 109 has a circumferential collar 111. Of the Lever 102 has in the region of the opening 109 on the collar 111 of the valve 1 18 facing side of the side cheeks of the opening 109 an effective area 110. This effective range 1 10 is designed as a protruding curvature, which is in engagement with the collar 11 1 of the valve 104. By applying force to the engagement portion 103 of the lever 102, a force is exerted on the collar 11 of the valve 104 by supporting the bearing portion 105 on the abutment 106, whereby the valve 104 is pulled away from the container reservoir 1 18. Optionally, the use of a bearing ring or a similar component is conceivable, which is inserted between the collar 111 of the valve 104 and the effective portion 110 of the lever 102. This serves to better power transmission between lever 102 and valve 104th

The present embodiment shows the dispenser 101 is at rest position, that is, the abutment 106 is configured such that, as the engagement portion 103 abuts against the outer wall of the reservoir reservoir 118, so that no pressure can be exerted on the lever 102 around the valve 104 to activate. For protection against external influences, the dispenser 101 has an aperture 122 and a cap 121.
