In particular comes as a dispensed material Ortschaum for sealing, insulation and bonding in the construction sector for use. It is also conceivable the issue of silicone or acrylate from a container.

Such donors have long been known. So Ortschaumdosen be offered, which after removal of a protective cap with an adapter having dispensing tube, which is attached to the container is provided. The dispensing tube is placed by means of the adapter on a tilting valve of the can, wherein in the region of the adapter at the same time a handling possibility in the form of a, a tilting movement of the valve performing lever is formed.

Next discloses the DE102004012470A1 an operating handle for a Ortschaumdose with an actuating lever for acting on a dispensing valve of the can and a dispensing tube, wherein for handling improvement of the operating handle is designed with such a size that it at least partially offers a gripping hand grip. The problem with the actuating handle shown is the poor dosability of the foam to be dispensed.

Further, the DE102009018528A1 a dispenser for dispensing material from a container via a dispensing valve with a lever which can be pivoted to actuate the dispensing valve, the container being provided with an adapter attachment for pivotally mounting the lever, having a support portion for mounting to the container; the lever is displaceable relative to the adapter attachment. The dispenser disclosed here is more suitable for ergonomic use compared to the above. However, for example, due to the design, in particular, disadvantages may result in the storage.

The object of the present invention is therefore to provide an improved dispenser which overcomes the above disadvantages.

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 the use of a dispenser for dispensing a material from a container via a dispensing valve and an dispensing extension, in particular an dispensing tube, a nozzle or a nozzle, wherein a cap is connected to the container, which has a cap top and which at least the dispensing valve partially surrounded with the cap, a lever for actuating the dispensing valve is pivotally connected about a pivot axis, wherein the cap has a first recess in which at least partially the lever is provided, so that parts of the outer surface of the cap are formed by the lever wherein the lever in turn in the region of the first recess of the cap, a second recess wherein, upon dispensing of the material, a projecting dispensing portion of the dispensing valve or a dispensing spike mountable on the dispensing valve extends through the second recess of the lever and thus also through the first recess of the cap.

Preferably, a pressure vessel is used as the container. The container may be designed substantially cylindrical and consist of a metallic material. In particular, tinplate or aluminum are suitable as materials. Preferably, a substantially metallic pressure cell is used as the container, wherein the two end faces are connected to the lateral surface via a fold.

Preferably, the container has the dispensing valve on its front side. In particular, known tilt or push valves can be used. Such valves permit dispensing of the material in the container, for example by tilting or displacement of a hollow central spindle, which is resiliently held by a rubber grommet on an assembly tray. The spindle is closed at its lower end by a sealing plate. When the spindle is tilted or displaced, the seal between the spout and the sealing plate is broken and the product in the container can reach passages in the central spindle and then flow along the hollow spindle.

The material to be dispensed is in particular a topping foam, in particular a polyurethane topping foam. Of course, the output of another material from the container is conceivable. In particular, silicone or acrylic materials are suitable. It is also conceivable, however, an output of coating materials such as paints or varnishes. In addition, a dispenser according to the invention can also be used in other technical fields, for example in cosmetics for dispensing body or hair care products or in the washing and cleaning agent industry for dispensing, for example, detergents.

On one end side of the container, where the dispensing valve is provided for dispensing the material in the container, the cap is attached. The attachment of the cap to the container can be carried out, for example, via the connection means known to the person skilled in the art. For example, in the case of a cylindrical pressure vessel having a protruding fold, on the end face provided with the dispensing valve, the cap can be rebound onto the protruding fold. Preferably, this compound is chosen such that it is not easy to solve, especially for children. For the connection, the cap may have a receiving area for receiving the protruding fold and / or provide connection means, such as snap-connection means, to allow a connection between the adapter cap and the container via the projecting fold.

For actuating the dispensing valve, a pivotable lever is provided. This is preferably pivotable relative to the container and relative to the cap about a pivot axis. The attachment of the lever is done on the cap. The lever is in operative connection with the dispensing valve. In this case, an indirect active connection can be provided by further components are provided between the lever and the valve. By pivoting the lever while the dispensing valve can be actuated to allow an output of the material in the container. When using a tilting or pushing valve as described above, the same can be tilted or displaced by means of a pivoting of the lever such that the material can flow and be dispensed along the hollow spindle of the dispensing valve.

The attachment of the lever to the cap can be designed such that a displacement of the lever relative to the cap is possible. Preferably, the lever has a first mounting area on which the connection with the cap can be provided and / or on which the operative connection with the dispensing valve can be provided as well as a second attack area, which provides a possibility of attack for the user. Here mounting area and attack area can be arranged angled to each other so that, for example, the mounting area on the top of the cap, in particular substantially flush with a cap top is arranged, the attack area of the lever in turn, for example, in the vicinity of the container outer surface, preferably at least partially along or extending in the direction of the container outer surface, is arranged. A pivoting of the lever for actuating the valve can be carried out in this design by a movement of the Angrifffläche towards the container outer wall. The pivoting of the lever can thus be limited by the container outer wall or upstream stop elements.

With such a lever, a displacement of the lever relative to the cap would result in a change in the distance between the engaging surface and the container outer wall. When using a substantially cylindrical container with a container axis, the engagement surface can be offset by a displacement of the lever relative to the cap radially with respect to the container axis. It is provided that by the displacement of the lever relative to the cap, the distance between the Angrifffläche and container outer wall is so small that a material output by an actuation of the Angrifefläche for pivoting the lever in the direction of dispensing valve for actuating the dispensing valve is not possible. The distance between the engaging surface and the container outer wall in this case is so small that insufficient lever travel would be provided for actuation of the dispensing valve by the lever. The dispenser is in this shift position of the lever relative to the adapter attachment in a rest position, in which no material issue is possible. This rest position is particularly suitable for storage or transport of the donor. The same can of course be achieved by a position of the lever relative to the cap, wherein the angled Angrifffläche rests against the outer wall of the container, so that a pivoting of the lever is impossible.

By displacing the lever relative to the cap, the distance between the angled engaging surface and the container outer wall may be increased so that the lever is then pivotable about the pivot axis for actuation of the dispensing valve. The limit of the lever travel can provide, for example, the container outer wall or upstream stops, which abuts the Angrifffläche during the pivoting of the lever. With the displacement of the lever relative to the adapter cap a variation of the distance between the engaging surface and the container outer wall can be achieved, with which a variation of the effective lever travel for actuating the dispensing valve via the lever is associated. The user can thus set by the displacement of the lever relative to the adapter attachment the maximum effective lever travel of the lever for actuating the valve. For example, a dispenser according to the invention can be designed and used in such a way that, to dispense the material, the gripping surface of the lever is always pivoted to a stop. The metering could in this case be effected solely by the displacement of the lever relative to the cap, in which the distance between the engagement surface and the stop and thus the effective lever travel can be varied.

In particular, the dispensing extension used may be a protruding portion of the dispensing valve itself or an adjunct member connectable to the valve and cooperating with said channel of the valve, such as a nozzle, spout, hose or similar, in particular, extension-type dispensing aid.

Particularly advantageous is the design according to the invention by the connection of the cap to the container, wherein the cap surrounds the dispensing valve at least partially. So, for example a protection of the dispensing valve are provided, so that the same is not inadvertently actuated during storage or during transport. In particular, for this purpose, the cap on a cap top, so that, for example, a force acting from above on the donor force does not act directly on the dispensing valve and the same possibly would operate unintentionally, but rather acts on the cap top. The top of the cap can be designed preferably flat, in particular to allow a stackability of several donors. It can also be prevented by suitable design that the dispensing valve and other moving parts are contaminated and could possibly no longer be operated due to the contamination. For this purpose, the cap is preferably closed except for said first recess. This can be done for example by the use of said cap top, which is followed by a coat-like cap side surface which open at the front of the dispenser, for example, both sides in a cap front side, which in turn may have said first recess. In an advantageous embodiment, the cap is designed in particular in the region of the transition to the container corresponding to the container and may in particular have the same or a similar shape. The first recess is used according to the invention, the recording of the lever, wherein the recess is preferably only slightly larger than the lever itself, so that the lever on the one hand is still free to move and can be pivoted about the pivot axis, on the other hand, however, the gap between the lever and the Recess limiting edge is as small as possible in order to provide the greatest possible protection for example, the dispensing valve.

The lever thus provides, at least in regions, in particular in the region of the first recess, the outer surface of the cap, wherein the lever in turn has its own second recess in this region. This second recess, when the dispenser is in use, serves to dispense the material by extending a projecting dispensing area of the dispensing valve or dispensing valve mountable on the dispensing valve through said second recess of the lever and thus also through the first recess of the cap, particularly at the dispensing of the material.

Another advantage is the use of a lever which projects beyond the cap in the direction of the underside of the dispenser and is at least partially adjacent to the container outer wall. By means of such a lever, for example, in the case of one-handed operation of the dispenser, the user can grasp, for example, said gripping surface of the lever with his fingers, whereby further regions of the hand rest on the container. Then the lever can be swiveled with your fingers towards the container. As a counter bearing thus the container itself can be used, which can lead to material savings in the cap. In addition, by a suitable design of this preferred lever leverage can be exploited, so that the effort of the user to operate the dispensing valve can be reduced.

Another advantage is the use of a lever having a lever front side, in particular having said Angrifffläche, which extends at least partially from the top of the dispenser in the direction of the bottom, wherein the lever in a first rest position in the region of the lever front side abuts the container outer wall, and wherein the lever is slidably mounted relative to the cap so as to be spaced apart from the container outer wall in a second activation position in the region of the lever front side, wherein the lever for actuating the dispensing valve for dispensing the material can be pivoted about the pivot axis. The above-described advantageous function of a displaceable lever is also applicable in this preferred embodiment and complements the extent in this section.

Another advantage is the use of a support member which is connected via a hinge connection with the cap, wherein the lever is so connected to the support member, that he together can be pivoted with the carrier element as a unit by means of the hinge connection for actuating the dispensing valve for dispensing the material with respect to the cap about the pivot axis. Such a configuration may prove useful, for example, in manufacturing. In particular, it is conceivable to manufacture the carrier element and the cap in one operation from a plastic material, in particular by means of an injection molding process and to provide a molding of the carrier element to the cap, wherein in particular a film hinge can be provided between the carrier element on the cap. The lever can be made in this case, for example, as a separate component, in particular of a different material and connected in a further process step with the carrier element.

When using a carrier element, it has also proven to be advantageous to arrange the lever slidably on the carrier element in order to change between the first rest position to the second activation position. The above-described advantageous function of a displaceable lever is also applicable in this preferred embodiment and complements the extent in this section.

In an advantageous development when using one of the embodiments described above having a displaceable lever, the second recess of the lever is dimensioned and designed such that the protruding through the second recess projecting output portion of the dispensing valve or the output extension neither in the activation position of the dispenser nor during a pivoting of the Levers about the pivot axis is influenced by a recess limiting edge region of the lever. In an advantageous development, said dispensing region or said dispensing extension is also not influenced in the rest position of the dispenser by an edge region of the lever delimiting the recess. Thus, activation and deactivation of the dispenser without affecting the position or position of the above dispensing area of the dispensing valve or dispensing extension may be enabled. Even with the output of the material by a pivoting of the lever, the projecting output range of the dispensing valve or the delivery extension is merely displaced by the displacement of the dispensing valve, but not directly influenced by the lever, in particular not bent by the lever.

In an advantageous development when using one of the above-described embodiments having a displaceable lever limiting means are provided which limit the displacement of lever to the cap and / or the support member. This is particularly advantageous to ensure a backup of the lever on the cap or the support element. The limiting means serves in particular as a captive of the lever, which limits the user in the displacement of the lever.

Another advantage is the equipment of the lever or the cap with at least one projection and the other with at least one recess, wherein a relative displacement of the lever to the cap, a locking of the at least one projection of the lever or cap in the at least one recess of the cap or levers leads. The same may prove to be useful for the use of a support element, in which case the corresponding components are formed according to lever and carrier element. This latching connection can in particular serve to provide predetermined positions of the lever relative to the cap, in which predetermined effective lever paths are provided upon pivoting of the lever for actuating the dispensing valve. When using a carrier element described above with which the lever is pivoted about the pivot axis, these locking connection means are preferably provided in each case on the lever and directly on the carrier element.

In an advantageous development, the lever has on its side facing the pivot axis and said lever front side and in particular the attack area opposite side a receptacle for a Ausgabefortsatz, in particular a spout, a nozzle or other above-mentioned and connectable to the dispensing valve output extension. The same receptacle can be formed on the lever: for example, it is conceivable to manufacture the lever from a plastic material and to manufacture the lever and receptacle by means of an injection molding process in a production step.

In this case, it has also been found to be particularly advantageous to mount the lever relative to the cap or to the carrier element slidably, wherein a displacement of the lever associated with a displacement of said receptacle for the output extension, wherein the receptacle in the rest position of the lever, in which he Area of the lever front side abuts against the container outer wall, projecting from the cap, that a receiving possibility for the output extension is provided, wherein the output extension in the received state at least partially extends such an angle through the sliding plane of the lever that the output extension in the recorded state, a shift of the Lever stops, and that the output extension of the lever for preferably first-time use of the dispenser is removable to a displacement of the lever in the activation position in which the lever in the region of the lever front side spaced from the container outer wall to the A to allow the material to be dispensed. The output extension located in the receptacle prior to the use of the dispenser and in the resting position of the dispenser thus acts as a safety device or lock and in particular can prevent unwanted or undesired displacement of the lever from the rest position to the activation position. This embodiment can be used in particular as a child safety. Only after the removal of the delivery extension, in particular for mounting the delivery extension on the discharge valve, a displacement of the lever from the rest position to the activation position is possible.

In an advantageous development of the invention, retaining means are provided on the receptacle and / or on the delivery extension in order to ensure attachment of the delivery extension to the dispenser, which are preferably deformed or destroyed during the separation of the delivery extension from the receptacle. In this way, on the one hand a backup of the donor can be made possible, on the other hand, a first opening assurance can be provided, which can indicate to the user the condition of the donor and can show, especially in the showroom, that it is a new and unused donor.

FIGS. 1 to 4 show a dispenser 1 according to the invention for dispensing a product or material from a substantially cylindrical container 2 with a container outer wall 5 and with a container axis 14. The container 2 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. In the present case, the dispenser 1 is used to dispense a local foam. This is a filling and / or insulating foam, in particular a ready-to-use, one-component and moisture-curing polyurethane foam.

On an upper side, the container 1 may have a dispensing valve for dispensing the material. In particular, known tilt or push valves can be used. Such valves permit dispensing of the material contained in the container 1, for example, by the displacement of 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 or displaced, the seal between the spout and the sealing plate is broken and the product in the container can reach passages in the central spindle and then flow along the hollow spindle. Such valves are well known in the art.

FIG. 1 shows a perspective view of the dispenser 1 with the container 2, which has a container outer wall 5. For dispensing of the material located in the container 1, a dispensing valve concealed in the present exemplary embodiment is provided on the upper side. The dispensing valve includes a substantially cylindrical channel for dispensing the material, wherein the axis of the channel in the present embodiment corresponds to the container axis 14. The dispensing valve is in the FIG. 1 covered by a cap 3, which is mounted on the top of the container 2. The cap 3 has a cap side surface 4, which is at least partially aligned with the container outer wall 5. At the top of the dispenser 1, the cap 3 also has a flat cap top 6, which is interrupted centrally by a first recess 7, wherein the recess 7 extends over the cap top 6 in a cap front 8, which forms the front part of the cap side surface 5 , Within the recess 7, a lever 9 is provided, which is connected to the cap front 8 opposite rear side of the cap 3 about a pivot axis 20 pivotally connected to the cap 3.

The lever 9 has at the top of the dispenser 1 on a lever top 10, which is substantially flush with the cap top 6. In the illustrated embodiment, both cap top 6 and lever top 10 are arranged approximately orthogonal to the container axis. In the direction of the cap front side 8, the shape of the lever 9 essentially follows the shape of the recess 7 extending from the cap top 6 over the cap front side 8, the lever 9 projecting beyond the recess 7 with an engagement region approximately parallel to and at a distance from the latter Container axis 14, in the example shown, partially along the container outer wall 5, extending in the direction of the underside of the dispenser 1. In approximately in the region of the transition from cap top 6 to cap front 8, the lever 9 further has an opening 12 as a second recess of the dispenser 1.

On the opposite side with respect to the cap front 8, an output spout 13 is provided, which is fixed by means of releasable connection means on a tab-shaped receptacle 19 of the lever 9. The receptacle 19 is integrally formed on the rear region of the lever 9 and is in the rest position of the donor 1 shown from the cap 3 from. The dispensing spout 13 can be removed by the user from the location shown for dispensing the material from the dispenser 1 and through the opening 12 of the lever 9 and thus also through the recess 7 of the cap 3 with the inside the cap 3 arranged dispensing valve are connected. For this purpose, the discharge spout 13 is designed as a hollow cylinder or tubular and has on one side not shown mounting means for mounting on the dispensing valve. When mounted, the dispensing spout 13 extends substantially parallel and thereby radially spaced from the container axis 14 along the cap side surface 4 and the container outer wall 5.

In the illustrated embodiment, the dispenser 1 is seen in the rest position. In this case, the lever 9 is located with its lever front side 11 on the container outer wall 5, so that no pivoting about the pivot axis 20 is possible. To use the dispenser 1, the lever 9 is slidably mounted with respect to the dispenser 3. The displacement follows approximately orthogonal to the container axis 14. Here, the lever 9 is moved so that the lever top 10 is moved within the recess 7 in the region of the cap top 6 relative to the latter, so that the lever front side 11, both from the cap front 8 and removed from the container outer wall 5.

However, since the receptacle 19 is provided at the rear portion of the lever 9, only the discharge spout 13 must be removed from said receptacle 19. As mentioned above, the discharge spout 13 extends substantially parallel and thereby radially spaced from the container axis 14 along the cap side surface 4 and the container outer wall 5, thus at an angle by the displacement plane of the lever 9, that the discharge spout 13 prevents a displacement of the lever in the received state , The dispensing extension located in the receptacle 19 prior to the use of the dispenser 1 and in the rest position of the dispenser 1 thus acts as a safety device or lock and can in particular prevent unwanted or undesired displacement of the lever 9 from the rest position to the activation position. This embodiment can be used in particular as a child safety. Only after the removal of the discharge nozzle 13, in particular for mounting the discharge nozzle 13 on the dispensing valve through the opening 12 of the lever 9 and thus also through the recess 7 of the cap 3, a shift of the lever 9 described above from the rest position to the activation position is possible ,

FIG. 2 shows a sectional side view of the dispenser 1 FIG. 1 , At the upper end side of the cylindrical container 2, on which also the dispensing valve 22 shown here for dispensing of the material located in the container 2 is provided, the cap 3 is attached. The container 2 has at said upper end face on a projecting fold on which the cap 3 is aufgeprellt. The cap 3 is substantially closed and encloses a cavity 28, in which the dispensing valve 22 is located. On the dispensing valve 22 is mounted or mounted a valve cap 25 which has a communicating with the hollow spindle of the dispensing valve 22 channel which opens in the direction of the top of the dispenser 1 in an angled channel extension to allow a simpler output of the material. At the unwound channel extension, the valve cap 25 has an external thread 26 to mount the output spout 13 with a corresponding internal thread 25 on the valve cap 25 for dispensing the material. In the exemplary embodiment shown, a delivery valve 22 is a push valve, wherein actuation of the hollow central spindle is displaced in the direction of the container axis 14. For safe guidance of the dispensing valve 22 during actuation, the cap 3 has a guide sleeve 29, in which the valve cap 25 and thus also the dispensing valve 22 is guided.

It can also be seen that the cap 3 comprises a carrier element 15 which is articulated to the rear, the recess 7 opposite cap side surface 4 via a film hinge 16. In this case, the lever 9 is connected to the carrier element 15 such that it can be pivoted together with the carrier element 15 as a unit by means of the film hinge 16 for actuating the dispensing valve 22 for dispensing the material with respect to the cap 3 about the pivot axis 20 extending through the film hinge 16 , In this case, the lever 9 is also displaceable on the carrier element 15 arranged to switch between the shown rest position of the dispenser 1 to the activation position. The displacement takes place in a guide, not shown, which is provided by the carrier element 15. For this purpose, the carrier element 15 has a corresponding guide groove in which corresponding guide means of the lever 9 engage. To limit the displaceability of the lever 9 selbiger has a protruding toward the cavity 28 projection 18 which allows a stop means a displacement of the lever 9 with respect to the support member 15 from a rear shoulder 30 of the support member 15 to a front shoulder 17 of the support member 15. In order to actuate the dispensing valve 22 by pivoting the lever 9 and the carrier element 15, the carrier element 15 has a protruding into the cavity 28 projecting pressure region 27 which is designed such that upon pivoting of the lever, a force approximately in the direction of the container axis 14 acts on the valve cap 25. For this purpose, the pressure region 27 is designed cam-shaped or rounded on its side facing in the direction of the valve cap 25 side.

In the rear area of the dispenser 1 is in FIG. 2 again provided the tab-shaped receptacle 19 for the discharge spout 13. The dispensing spout 13 includes a long dispensing tube 23 for precise placement of the material upon dispensing. In addition, the dispensing spout 13 includes a connector having an internal thread 24 for mounting the dispensing spout 13 on the valve cap 25 after insertion of the dispensing spout 13 through the dispensing spout 13 Opening 12 of the lever 9 with the external thread 26 of the valve cap 25 can be brought into engagement. In the region of the internal thread 24, the connecting element of the dispensing spout 13 also has a radially projecting collar which serves to secure the position of the dispensing spout 13 in the receptacle 19. In addition, retaining means, not shown, are provided on the receptacle 19 and on the dispensing spout 13 to ensure attachment of the dispensing spout 13 to the dispenser 1, which are destroyed in the separation of the dispensing spout 13 from the receptacle 19 to provide a Erstöffnungssicherung. As mentioned above, the dispenser 1 is in FIG. 2 in the rest position, wherein the lever 9 rests with its lever front side 11 on the container outer wall 5, so that no pivoting of the lever 9 about the pivot axis 20 is possible. In order to change from the rest position to the activation position, the lever 9 is displaceably mounted, wherein - as mentioned above - the discharge spout 13 is provided as a displacement safeguard and is therefore to be removed from a possible displacement of the lever 9 from the receptacle 13.

FIG. 3 shows a sectional side view of the dispenser 1 FIG. 1 in activation position. In the present embodiment, the lever 9 in contrast to in the FIGS. 1 and 2 shown variants in the direction of the front of the dispenser 1 relative to the support member 15 and the cap 3 has been moved. The lever 9 is now located with its angled attack area spaced from the container outer wall 5 of the container 2. To enable a shift, the discharge spout 13 was removed from the receptacle 19, through the opening 12 of the lever 9 and the recess 7 of the cap 3 in the Cavity 28 introduced and connected there by means of the internal thread 24 and the corresponding external thread 26 with the valve cap 25. The displacement of the lever 9 was carried out until the abutment of the projection 18. At the front stop 17 of the support element 15th

FIG. 4 shows a sectional side view of the dispenser 1 FIG. 1 with actuated lever 9, wherein the lever 9 has been pivoted about the pivot axis 20 relative to the cap 3, that said angled attack region of the lever 3 rests against the container outer wall 5. The pivoting of the lever 9 was carried out as a unit together with the support member 15 is provided about the hinge 16. During the pivoting of the lever 9, the cam-shaped or rounded pressure region 27 of the carrier element 15 is moved in such a way that it experiences a rolling contact with its cam-shaped or rounded shape on the upper side of the valve cap 25 and at the same time in this area exerts pressure on the valve cap 25 such that the same is displaced along the container axis 14 in the direction of the container 2. The displacement of the valve cap 25 in the direction of the container 2 is accompanied by a displacement of the dispensing valve 22 so that the same is opened and a material dispensing through the hollow spindle of the dispensing valve 22, the valve cap 25 and finally the dispensing spout 13 is possible. As can be seen, the opening 12 of the lever 9 and, of course, the recess 7 are dimensioned such that the protruding discharge spout 13 neither in the in FIG. 3 shown activation position of the dispenser 1, still during the in FIG. 4 shown pivoting of the lever 9 about the pivot axis 20 of the opening 12 and the recess 7 bounding edge region of the lever (9) and the cap 3 is influenced. The same is also conceivable for a in FIG. 2 shown rest position of the dispenser 1 to mount the dispensing spout 13 in the rest position of the dispenser 1 on the valve cap 25.
