Description

The invention relates to a device for dispensing a product from a container. Such devices are particularly useful for squeezing viscous masses, e.g. Jointing compounds used from containers such as cartridges or tubular bags. Known devices consist of a receiving unit for the container containing the material to be dispensed, a dosing unit and a permanently connected to receiving unit handle. Various applications are known for dispensing the material in the container. In many cases, a dosing unit is used, which has a displaceably mounted piston rod with a piston which presses against the inserted container, so that the contents of the container can be dispensed dosed. Another possibility is the use of a pneumatically acting metering unit, wherein by means of a pressure medium, a piston for dispensing the material can be moved within the container.

Known devices for dispensing a product from a container, for example, with the US2005 / 0023301A1 , of the EP1762507A , of the US4273270A , of the GB1589381A , of the US2692706A and the US3319839A disclosed.

Another example of such a device shows the DE 8620379 U1 , The disclosed apparatus for strand-like discharge of pasty masses contained in deformable tubular bags has a cylinder which serves to receive the tubular bag. The cylinder has a central opening which is aligned with a Tüllenanschluss the tubular bag. To output the mass located in the tubular bag, an axially displaceable against the tubular bag, substantially piston-shaped pressure piece and means for axial displacement of the pressure piece are provided in the cylinder. The displacement of the pressure piece is pneumatic. For this purpose, a compressed air connection is provided on the handle of the device. The pressure acting on the pressure piece air pressure and thus the axial propulsion of the pressure element within the cylinder can be adjusted via a lever-actuated pressure valve. A major disadvantage of this device is the fixed volume of the cylinder for receiving the tubular bag. This is fixed, so that the size of the tubular bag is not arbitrary.

Other tube bag guns are also known in the prior art. These tubular bag guns usually have a cylindrical receiving unit made of aluminum or similar materials for the tubular bag. The receiving unit includes a discharge end for dispensing the material contained in the tubular bag and on the opposite side a connection area with which the device with the handle and the dosing unit can be screwed in the rule. In this type of tubular bag guns, although it is provided to use recording units of different lengths, which tube bags can be pressed different lengths longer, but this leads to further disadvantages. Especially in the construction sector Tubular bag with a large content of advantage, since the time required for the replacement of an empty tubular bag can be reduced due to the short replacement intervals. Since the diameter of the cylindrical receiving unit is fixed by the screw, the receiving unit for a tubular bag would have to be longer, the larger the volume of the container, or the greater the amount of material to be dispensed. However, particularly long recording units can not be used throughout the construction sector. Especially in confined spaces, under stairs or in the grouting of corner areas, the work is significantly hampered by a long recording unit. Another disadvantage is the resulting torque, which acts on the handle of the device and thus on the user. The longer the receiving unit, the greater the torque acting on the handle. Ergonomic working with such a device is no longer possible.

The object of the present invention is therefore to provide an improved device for dispensing a material contained in a container, which ensures ergonomic working with containers of different sizes.

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 provide a device for dispensing a product from a container, comprising an assembly comprising a cavity-containing receiving unit for the container and a propelling element for dispensing the product within the receiving unit, with a handle connected to the receiving unit a metering unit, wherein the connection between the handle and receiving unit is releasable to ensure interchangeability of the assembly, wherein for mounting or dismounting between the handle and receiving unit in a first embodiment, a means for linear mounting is provided which translational relative movement between the receiving unit and handle allows, or in a second embodiment, a joint is provided and wherein a coupling part of the handle and a coupling part of the receiving unit in the mounted state of the receiving unit on the handle a Kup Plung provide to enable an operative connection between the metering unit of the handle and the drive element in the receiving unit wherein the coupling part of the handle is fixedly fixed to the handle such that a displacement of the receiving unit via the means for linear mounting relative to the handle in the first embodiment or a pivoting of the receiving unit relative to the handle via the joint in the second embodiment leads to a production of said active connection ...

Such a construction of a device for dispensing a product from a container brings many advantages. In particular, the interchangeability of the assembly, i. the receiving unit with the propulsion device and the use of a coupling part on the handle and a corresponding coupling part on the receptacle, a use of receiving units of different dimensions conceivable. Preferably, substantially cylindrical receiving units with different diameters are used. This has the advantage that containers of any diameter can be used without the device has too long a design that could hinder the user at work. In this case, cartridges, tubular bags as well as all other containers used in the construction, artisan or industrial sector, which are suitable for pressing out by means of such a device, can be used as containers. The clutch used can be both a pneumatic and a mechanical clutch. Pneumatic couplings are particularly suitable when using a device in which the drive element is displaced by means of a pressure medium within the receiving unit. Mechanical couplings are used in particular in devices in which the propulsion element is displaced, for example via a displaceable piston rod within the receiving unit.

Another advantage is the use of a bearing on the handle, which fixes the receiving unit relative to the handle at least counter to the direction of displacement of the output of the product within the receiving unit slidably disposed driving element. This bearing serves in particular as an abutment for the propulsion of the displaceably arranged driving element used for coming force. The receiving unit preferably has a dispensing opening for dispensing the product in the container. To output the product, the propulsion element is displaced within the receiving unit in the direction of the opening of the receiving unit and thus presses out the product located in the container through the dispensing opening of the receiving unit. The force required for propulsion of the propulsion element depends, in particular, on the friction of the propulsion element on the receiving unit, on the density of the product to be dispensed, on the friction of the container on the receiving unit and on the size of the dispensing opening of the receiving unit. In particular, in order to prevent that the acting force solves the connection of the handle and the recording or the operative connection between the dosing unit and the driving element, the bearing is provided to intercept the forces acting on the receiving unit and, for example, on the handle or to transfer other components of the device. In this way, it is ensured that a secure hold of the receiving unit on the handle and thus a reliable function of the device are ensured even with a large force.

Another advantage is the use of a locking option to fix the receiving unit in the mounted state on the handle and a release of the connection between the receiving unit and to prevent handgrip. Such a lock is particularly advantageous when working, in which the device is guided in different positions and angular positions. By locking the receiving unit on the handle unintentional release of the receiving unit is avoided by the handle, so that lost work can be excluded. According to the invention in a first embodiment, the use of a means for linear storage between the handle and receiving unit is provided, which allows a translational relative movement between the receiving unit and handle to provide the detachable connection between the receiving unit and handle. Such storage has proved to be particularly advantageous. The receiving unit can be moved for replacement via the means for linear storage relative to the handle and assembled or disassembled in this way. Flat or prismatic guides between the receiving unit and the handle are particularly suitable for a means for linear storage. These allow in particular the absorption of forces perpendicular to the guideway. A lifting of the guide and / or pivoting within the guide track plane can be avoided. In order to prevent unintentional lifting of the receiving unit from the guideway also known to those skilled guide or Umgriffleisten can be provided.

In the use of said first embodiment, the use of a coupling part of the handle is further provided according to the invention, which is fixedly fixed to the handle. With such a coupling part, a particularly simple operative connection between the dosing unit and the driving element is provided. The user only has to make the connection between the receiving unit and the handle, for example via an o.g. Produce means for linear storage, which leads to a production of the active connection between the dosing unit and the driving element. A maloperation and a resulting faulty operative connection between the dosing unit and the drive element is precluded by such a fixedly fixed to the handle coupling part. In addition, it is prevented by the stationary fixation that the coupling between handle and receiving unit can be solved automatically while working with the device and so the operative connection is unintentionally separated.

Another advantage is the use of a handle having an elongated guide groove, the receiving unit having a guide slide which can be engaged with the guide groove of the handle to provide a means for positioning the receiving unit on the handle. Such a design of the handle and the receiving unit, a particularly simple assembly and disassembly of both components can be ensured. To change the receiving unit, the user only has to insert the guide carriage of the receiving unit into the guide groove of the handle and can thus displace both components against one another in order to achieve assembly or disassembly. A malfunction is almost impossible with such a design.

Alternatively, it may be advantageous to provide the receiving unit with an elongated guide groove, wherein the handle has a guide carriage, which can be brought into engagement with the guide groove of the receiving unit to provide a means for positioning the receiving unit on the handle. Even with such a solution, a particularly simple assembly and disassembly of both components is possible. Here only the guide carriage of the handle must be inserted into the elongated guide groove of the receiving unit to allow assembly or disassembly.

Another advantage of using a connection via an elongated guide groove or a guide carriage is the design of the guide carriage with guide or Umgriffsleisten that prevent lifting of the standing in engagement with the guide slot carriage. By this dovetail-like guide a special secure connection can be ensured as a lifting of the receiving unit is avoided by the handle. Also conceivable is the use of a known to those skilled obliquely arranged wedge bar, which allows for adjustability of the dovetail-like guide.

Another advantage is the use of a handle, wherein a connection for a pressure medium is provided which is in communication with the dosing unit and the operative connection between the dosing unit and the drive element is provided via a sealed plug-in coupling between receiving unit and handle. Devices of this type are particularly suitable in construction sites, since here are usually suitable print media available. To regulate the pressure medium, the dosing unit can have a valve which can be actuated by a lever, as well as a pressure gauge and an additional pressure regulator.

Another advantage of using a pressure medium is equipment of the handle with a protruding coupling part, wherein a corresponding opening is provided on the receiving unit and wherein the protruding coupling part and the corresponding opening form the plug-in coupling in the mounted state of the receiving unit on the handle. This design of the coupling has proven to be particularly advantageous because with such a design, the components used for the receiving unit, which provide the coupling part are reduced to a minimum. Thus, an exchanged receiving unit can be safely stored in a toolbox, in a building container or between building materials, without the coupling part is damaged, since this is only an opening into which engages the protruding coupling part of the handle during assembly. Since it is provided in the present device to use the handle when replacing the receiving unit with a new or larger, a cost can be reduced by the equipment of the receiving unit with an opening as a coupling part. The more complex coupling part of the handle remains, whereas the interchangeable receiving units have only the corresponding and inexpensive to be realized openings as coupling parts.

Another advantage of equipping the receiving unit with an opening is the use of a circumferential sealing ring to provide a seal of the plug-in coupling in the assembled state of the receiving unit on the handle. Such a sealing ring can in particular compensate for manufacturing tolerances or take over a seal when areas of the protruding coupling part of the handle or the corresponding opening are provided with dust, dirt or moisture.

As an alternative to operating the device via a pressure medium, it may be advantageous to displace the propulsion element for dispensing the product via a mechanical propulsion means, which is in operative connection with the metering unit and which can be coupled to the propulsion element for receiving unit for dispensing the product. Preferably, the metering unit has a displaceably mounted piston rod, wherein on the handle a movable, generally pivotable actuating lever is provided, which cooperates with the piston rod. By manually pressing the actuating lever, the piston rod is moved and can thus move the propulsion element within the receiving unit. As a possibility for coupling between the driving element and the propulsion means, all suitable mechanical coupling possibilities known to the person skilled in the art can be used. In particular, snap, screw or clamp connections are suitable.

Another advantage is the use of a substantially cylindrical receiving unit and a tubular bag as a container for the product to be dispensed. Such tubular bags or film cartridges called, are particularly suitable for viscous or pasty masses, however, in contrast to known cartridges or similar solid-walled containers very little material is required for the shell of the tubular bag. Tubular bags are usually made from a film tube. After the filling process, the ends of the tube are closed like a lint. Mostly clamps, clips or adhesive or welding seams are used.

The receiving unit 200 is detachably connected to the handle 100. The receiving unit 200 has a hollow cylindrical shape and serves to receive a container, not shown, filled with the product to be dispensed. The product is dispensed at a delivery end 204 of the receiving unit 200. For this purpose, a metering device 101 is provided on the handle 100, by means of which the user can regulate the output of the product contained in the container. In the present embodiment, it is a pneumatically acting device, wherein the output of the product is made possible by the use of compressed air. For this purpose, a compressed air connection 105 is provided on the handle 100. At this compressed air connection 105, the user can connect a pressure medium, such as a compressor. To regulate the pressure, a pressure regulator 104 is attached to the handle 100. By means of a manometer 103 provided on the handle 100, the user can read the pressure applied to the device and adjusted via the pressure regulator 104. To regulate the pressure for the output of the product, the metering unit 101 can be operated via an actuating lever 102, which is attached to the handle 100 and can be pivoted in the direction of the handle 100. On the degree of pivoting of the operating lever 102 and the set air pressure on the pressure regulator 104, the output of the product in the container can be regulated. In the receiving unit 200, the propellant element, not shown, is provided for dispensing the product, which can be displaced within the receiving unit 200. By applying pressure to the drive element selbiges is moved and pushes the container arranged in the receiving unit with the material to be dispensed in the direction of discharge end 204 of the receiving unit 200. The receiving unit 200 has at the discharge end 204 on a cap 205. This cap 205 is connected in the present embodiment via a screw thread with the cylindrical receiving unit 200 and has a concentric with the hollow cylindrical shape of the receiving unit 200 opening. The product can be dispensed from the container located in the receiving unit 200 via this opening. When mounting the cap 205 on the receiving unit 200, a nozzle, not shown, may be mounted between the cap 205 and the receiving unit 200 to facilitate product dispensing and dispensing fine beads or beads to product. At the end of the receiving unit 200 opposite the delivery end 204 of the receiving unit 200, the same has an abutment side 206. With the stop side 206, the receiving unit 200 bears against a stop region 123 of the handle 100. The stop region 123 is provided on the connection region 122 of the handle 100, with which an operative connection between the dosing unit 101 of the handle 100 and the receiving unit 200 for dispensing the product can be produced. To secure the position of the mounting unit 200 mounted on the handle 100, a locking means 115 is provided on the handle 100.

FIG. 2 shows a partially sectioned side view of the device according to the invention FIG. 1 with a handle 100 and a replaced assembly with a receiving unit 200, which opposite to the FIG. 1 shown receiving unit 200 has a larger diameter. Due to the larger size of the receiving unit 200 larger container can be used with a larger product content, so that you can work longer with the device without a deflated container must be replaced with a new one. The receiving unit 200 has a cavity 201 which serves to receive the product-filled container. In addition, a drive element 209 is arranged in the cavity, which can be moved to output the product within the cavity 201. The propulsion element 209 is substantially cylindrical. In this case, the diameter is dimensioned such that the drive elements 209 with the inner wall of the cavity 201 seals tightly. For this purpose, mechanical sealing means can additionally be provided on the driving element 209 and / or fats or oils can be used as a sealant between the driving element 209 and the cavity wall. For working with the device, a container is inserted into the space between discharge end 204 and drive element 209 and fixed by means of the closure cap 205 and / or a nozzle, not shown.

By the in FIG. 3 shown perspective sectional view of the device FIG. 1 along the section line AA, the connection between the handle 100 and the receiving unit 200 can be seen. The receiving unit 200 has a guide carriage 202 with guide rails 203. The handle 100 in turn has a corresponding guide groove 121 into which the guide carriage 202 can be inserted with the guide rails 203. For mounting the receiving unit 200 on the handle 100 of the guide carriage 202 is brought into engagement with the guide rails 203 with the guide groove 121 and the receiving unit 200 is moved relative to the handle 100 in the direction of connection portion 122 of the handle 100 that the abutment side 206 of the receiving unit 200 at abuts the stopper portion 123 of the handle 100. By the guide groove 121 and the guide carriage 202, a means for linear mounting is provided, which allow a translational relative movement between the receiving unit 200 and the handle 100 for mounting or dismounting of both components. The guide rails 203 prevent loosening of the connection between the handle 100 and receiving unit 200 by avoiding lifting of the receiving unit 200 of the handle 100. To ensure after mounting the receiving unit 200 on the handle 100 to secure the position of the components to each other, the locking means is used 115 as a locking option to fix the receiving unit 200 in the mounted state on the handle 100 and to prevent loosening of the connection between the receiving unit 200 and handle 100. At the same time, the locking means 115 assumes the function of a bearing which fixes the receiving unit 200 counter to the direction of displacement 210 of the driving element 209 displaceably mounted within the receiving unit 200 in order to dispense the product. The handle 100 has substantially parallel to the guide groove 121 extending end edges 119 with chamfers 120, which are aligned in the mounted state of the receiving unit 200 on the handle 100 with the lateral surface of the receiving unit 200. In this way, the means for linear storage between handle 100 and receiving unit 200, the guide groove 121, the guide carriage 202 and the Guide rails 203 are protected from contamination. Alternatively, the receiving unit 200 may be equipped with a guide groove, not shown, and the handle 100 with a corresponding, in the guide groove of the receiving unit 200 can be introduced, not shown guide carriage. This guide carriage of the handle 100 can also be equipped with guide rails, not shown.

FIG. 4 shows a partially cutaway rear perspective view of the device FIG. 1 , which discloses the coupling between the handle 100 and the receiving unit 200, which provides an operative connection between the metering unit 101 of the handle 100 and the driving element 209 of the receiving unit. The metering unit 101 includes a pressure line 106 extending inside the handle 100, which opens into a manifold neck 107 in the connection area 122. The manifold neck 107 is designed T-shaped and is attached to fix the position in the connection area 122 on a protruding from this fixing member 124. Further, the manifold neck 107 has a coupling member 108, which faces towards receiving unit 200 and tapers in this direction. The receiving unit 200 has an opening 207, into which when mounting the receiving unit 200 on the handle 100, the tapered coupling member 108 can be introduced. Thus, the opening 207 of the receiving unit 200 provides the corresponding coupling counterpart to the coupling member 108 of the handle. In the mounted state of the receiving unit 200 on the handle 100, the opening 207 and the coupling member 108 form a coupling to provide an operative connection between the metering unit 101 of the handle 100 and the driving element 209 of the receiving unit 200. For sealing a circumferential sealing ring 208 is provided at the opening 207. Through this sealing ring 208 and manufacturing tolerances on one of the two coupling parts, the coupling member 108 or the opening 207 can be compensated. The released via the actuating lever 102 pressure medium passes through the pressure line 106 and the manifold 107 via the provided through the opening 207 and the coupling member 108 clutch in the receiving unit 200 and acts on the driving element 209 that this is moved within the receiving unit 200.

FIG. 5 shows a sectional view of the device FIG. 1 along the section line BB by the locking means 115. The locking means 115 has a bore with which selbiges in the interior of the handle 100 on a transverse to the handle 100 arranged pin-shaped extensions 117 of the handle 100 is slidably mounted. Between the inner wall of the handle 100 and the locking means 115, a prestressed spring 118 is provided on the pin-shaped extension 117, which presses the locking means 115 in the direction of the opposite wall side of the handle 100. The locking means 115 has on its side facing the receiving unit 200 side projections 116, which engage in the assembled state of the receiving unit 200 in the guide groove of the handle 100 and in a not shown interruption of the guide rails 203 of. The projections 116 are arranged such that they are in Resting state of the locking means 115 engage in the guide groove. To mount a receiving unit 200, the user must therefore press the outside of the handle 100 projecting portion of the locking means 115 in the direction of the handle 10 against the tension of the spring 118, so that the projections 116 release the guide groove for the guide rails 203. Subsequently, the receiving unit 200 can be pushed onto the handle 100. The interruption of the guide rails 203 is provided such that the locking means 115 engages automatically by the tension of the spring 117 upon reaching the final assembly position of the receiving unit 200 on the handle 100 in the guide groove and the interruption and thus fixes the receiving unit 200 on the handle 100. Before disassembly, the user must again push the outside of the handle 100 protruding portion of the locking means 115 in the direction of the handle 10 against the tension of the spring 118, so that the projections 116 release the guide groove and the guide rails 203 no longer block.

FIG. 6 shows a partially sectioned side view of a device not according to the invention with a handle 100 and a mounted receiving unit 200. In this device, the displacement of the driving element 209 within the receiving unit 200 by means of a mechanical propulsion means, a displaceable cylindrical piston rod 109. This may be both a rigid , as well as a flexible Kolbestange 109 act. For a displacement of the piston rod 109 propulsion systems are suitable, which are also used in commercial cartridge or Schlauchbeutelpistolen used. An appropriate such propulsion system by the metering unit 101 is for example in the DE 102006037623 described. The mounting of the receiving unit 200 on the handle 100 is synchronous to the in FIG. 1 described device via a guide and a guide carriage with guide rails. For a fixation of the receiving unit 200 on the handle 100, a locking means 115 is provided. The receiving unit has an opening 207, in which during assembly of the receiving unit 200 on the handle 100, the piston rod 109 is inserted. The drive element 209 arranged in the receiving unit is subsequently connected via a coupling to the piston rod 109 in order to provide an operative connection between the dosing unit 101 and the drive element 209. In the present exemplary embodiment, the drive element 109 has a sleeve pointing in the direction of the piston rod 109 into which the piston rod 109 is inserted. The piston rod 109 has in a recess a shape of a ball 111 formed coupling member which is biased by a spring member 110 such that it is radially pressed with respect to the piston rod 109 to the outside, so that it protrudes partially from the surface of the piston rod 109 , Upon insertion of the piston rod 109 into the sleeve of the drive element 209, the ball 111 passes into a circumferential coupling groove 112 of the drive element 209 so that a positive connection between the piston rod 109 and the drive element 209 and an operative connection between the metering unit 101 and the drive element 209 is formed. To dispense the product, the piston rod 109 is moved by means of the metering unit 101 in the direction of the dispensing opening of the receiving unit 200 and thus displaces the locking member 115 within the receiving unit 200. The locking means 115 serves not only as a locking means to fix the receiving unit 200 in the mounted state on the handle 100 but also takes over the task of a bearing, which the receiving unit 200 against the direction of displacement of the output of the Product within the receiving unit 200 slidably mounted driving element 209 fixed.

FIG. 7 shows a partially sectioned side view of an alternative embodiment of the invention with the handle 100 with a metering unit 101 and the mounted receiving unit 200 with the drive element 209. The device has a hinge, which consists of a first hinge portion 125 of the handle 100 and a corresponding second hinge portion 211 of Receiving unit 200 is formed, which are connected via a snap connection. Around the hinge, the receiving unit 200 can be pivoted relative to the handle 100. The hinge is configured to allow separation of the receiving unit 200 and handle 100 via the hinge. To produce an operative connection between the drive element 209 and the dosing unit 101, the receiving unit 200 has an opening 207 into which a coupling member 108 of the handle can be introduced. For fixing the position of the mounted receiving unit 200 on the handle 100, a displaceable locking means 115 is provided, which prevents unintentional pivoting of the receiving unit 200 relative to the handle 100. The bearing which fixes the receiving unit 200 relative to the handle 100 against the direction of displacement 210 of the drive element 209 is realized by the joint.

FIG. 8 shows the device FIG. 8 with pivoted receiving unit 200 relative to the handle 100 about the joint. For this purpose, the locking means 115 has been solved.
