Exemplarily, the additional instrument 8 is mounted, in particular removably mounted, on the drive instrument 26. The stabilizing handle 5 is subordinate to the additional instrument 8. The additional instrument 8 is preferably implemented as a scroll device extruder additional instrument. The additional instrument 8 can also be implemented as a tubular bag extruder additional instrument.

[0043] The driving instrument 26, in particular the screwing and / or drilling instrument 7, comprises a drive interface 27 for providing a drive rotational movement, which is generated in particular by means of the electric drive 16. The additional instrument 8 comprises a driven interface 28 for receiving the drive rotational movement provided at the drive interface 27. The additional instrument 8 is connected or can be connected to the drive interface 27 of the driving instrument 26 by means of the driven interface 28.

[0044] Preferably, the additional instrument 8 is rotatable relative to the screwing and / or drilling instrument 7 about a rotation axis 9 oriented parallel to the longitudinal direction of the liquid container press 10, 20. Exemplarily, the liquid container press 10, 20 comprises a rotary bearing, by which the additional instrument 8 is rotatably supported about the rotation axis 9 or can be supported on the screwing and / or drilling instrument 7. Expediently, the additional instrument 8 can be rotated relative to the screwing and / or drilling instrument 7 by means of the rotary bearing in an angular range of at least 100 degrees, in particular at least 140 degrees.

[0045] The receiving portion 1 is configured to receive a liquid container 2. The receiving portion bottom 29 of the receiving portion 1 is shaped in particular corresponding to the shape of the liquid container 2. Exemplarily, the liquid container 2 has a cylindrical, in particular cylindrical shape. The receiving portion bottom 29 defines a cylindrical segment-shaped receiving recess, which corresponds to the cylindrical shape of the liquid container 2 and into which the cylindrical liquid container 2 can be inserted. The receiving recess is in particular groove-shaped. Exemplarily, the receiving portion 1 is implemented as a bearing shell, in particular as a bearing shell that is open toward the top. The receiving portion 1 can also be referred to as an open receiving portion 1.

[0046] The receiving portion 1 comprises a front stop structure 31, which is arranged in particular at the front end 11 of the receiving portion 1. The front end 11 of the receiving portion is the end of the horizontal section 23 facing away from the drive device 26 in the (negative) x direction. The front end 11 is in particular at the front end side of the rod section 25. Suitably, at the front end 11, liquid flows out of the liquid container 2. The stop structure 31 is used for the contact of the liquid container 2 and in particular for supporting the liquid container 2 in the (negative) x direction and / or in the radial direction. The stop structure 31 is exemplarily implemented in an annular or annular segment shape, wherein the annular axis is suitably oriented parallel to the x direction. The stop structure 31 suitably has a recess into which the liquid container 2 can be placed with the end side of its cylindrical container body 32. The recess is in particular annular or annular segment shape. The stop structure 31 further comprises a central through-hole 33 through which an outflow element 34 of the liquid container 2 , in particular an outflow nozzle, projects when the liquid container 2 is inserted into the receptacle 1 . The stop structure 31 expediently occupies less than 10% of the x extension of the receptacle 1 .

[0047] Exemplarily, the receptacle 1 is open (except for the stop structure 31 at the front end 11) to the top (that is, in the z direction) and to the sides (that is, in the positive and / or negative y direction), in particular completely open. Preferably, the receptacle 1 is limited in the x region (which starts from the stop structure 31 in the positive x direction and extends to the rear end of the receptacle 1 (in the positive x direction)) only by the receptacle bottom 29 (that is, in particular only to the bottom) and is otherwise suitably not restricted, in particular not to the top and / or to the sides. Suitably, the receptacle 1 is completely open in the entire x region starting from the stop structure 31 over an angular range of at least 140 degrees or at least 180 degrees around the longitudinal axis of the receptacle 1. Suitably, the x extension of the receptacle 1 is at least 20% or at least 30% of the x extension of the liquid container extruder 10, 20.

[0048] Figure 2 An exemplary design of a liquid container 2 is shown. The liquid container 2 comprises a container body 32, which is particularly cylindrical, preferably cylindrically shaped. Exemplarily, the container body 32 is implemented in a hollow cylindrical shape. The longitudinal axis of the container body 32 is oriented parallel to the x-direction. The container body 32 has a front end side 38 and a rear end side 39, which are suitably oriented perpendicular to the x-direction. The rear end side 39 is suitably designed to be open in the x-direction, so that the receiving space 37 (for receiving the extrusion element 12) can be approached through the rear end side 39. The receiving space 37 is limited in the radial direction by the hollow cylindrical body section 41 at the rear of the container body 32. In addition, the receiving space 37 is limited in the negative x-direction by the pressing section 36, which is particularly disc-shaped. The receiving space 37 is open in the positive x-direction. The receiving space 37 is particularly cylindrical.

[0049] The liquid container 2 is preferably implemented as a scroll device, in particular as a seam sealing material scroll device, for example as a silicone scroll device or an acrylic resin scroll device. The liquid container 2 comprises a liquid space 35 arranged in a container body 32, in which there is a liquid to be discharged. The liquid is in particular a seam sealing material, such as silicone or acrylic resin.

[0050] The liquid container 2 comprises an outflow element 34, which is in particular designed as an outflow nozzle and is expediently oriented with its longitudinal axis parallel to the x-direction. The outflow element 34 is arranged at the front end side 38. The liquid container 2 further comprises a pressing section 36, which, when pressed, reduces the liquid space 35 so that the liquid flows out of the liquid container 2 through the outflow element 34. The pressing section 36 is arranged at the rear end side 39 and / or can be approached through the rear end side 39.

[0051] The pressing section 36 can be moved in particular along the (negative) x direction in order to promote the outflow of liquid. The negative x direction should also be referred to as the forward direction and the positive x direction as the backward direction. Exemplarily, the pressing section 36 is disc-shaped. The pressing section 36 is placed in the hollow cylindrical container body 32 and can be moved relative to the hollow cylindrical container body 32 along the x direction in order to reduce the liquid space 35. The pressing section 36 can also be referred to as a piston element or as a bottom, in particular as a vortex device bottom. There is a receiving space 37 on the side of the pressing section 36 facing away from the liquid space 35 for accommodating the extrusion element 12 of the extrusion mechanism 3.

[0052] The pressing mechanism 3 comprises a pressing element 12, by means of which the pressing section 36 can be pressed (in the negative x direction) in order to cause the liquid to flow out of the liquid space 35. The pressing element 12 is also used to support the liquid container 2 (which is inserted into the receptacle 1 and rests against the front stop structure 31) in the (positive) x direction and / or radial direction (in particular the z direction and / or the y direction) and thus to lock the liquid container 2 in the receptacle 1; that is, in particular to fix it in the receptacle 1 in such a way that the liquid container 2 cannot be removed from the receptacle 1.

[0053] Extrusion element 12 comprises, by way of example, an extrusion head 42 which can be inserted into receiving space 37 and / or can be placed directly against pressing section 36. Extrusion head 42 is exemplarily implemented as an extrusion die and has, in particular, a disk-shaped end section. A rod section 43 is connected to extrusion head 42 along the (positive) x-direction. Rod section 43 is, in particular, implemented as spindle 18 and expediently has a thread, in particular an external thread. Rod section 43 is oriented with its longitudinal axis parallel to the x-direction.

[0054] The additional instrument 8 comprises the rod section 25 explained above. The additional instrument 8 also comprises a rear longitudinal section 44 connected to the rod section in the (positive) x direction. Exemplarily, the rear longitudinal section 44 extends behind the drive instrument 26 in the (positive) x direction, in particular behind the carrying handle 4 (in the following state, in which the additional instrument 8 is placed on the drive instrument 26). The rear longitudinal section 44 is used in particular to accommodate the rod section 43 of the extrusion element 12.

[0055] The extrusion mechanism 3 further comprises a drive device 51 for driving the extrusion element 12. The drive device 51 is used to drive the extrusion element 12 in the forward direction, so as to cause the liquid to flow out of the liquid container 2. The drive device 51 is particularly designed to convert the driving rotational movement provided by the drive device 26, in particular the electric drive 16, into a linear movement of the extrusion element 12. The linear movement is particularly a forward movement, preferably a forward movement in the (negative) x direction.

[0056] exist Figures 6 to 9 An exemplary design of the drive device 51 can be seen in . The drive device comprises a drive element 17, which is coupled to the extrusion element 12 and is used to drive the extrusion element 12. The drive element 17 can be placed in a driven rotational movement based on the driving rotational movement (provided by the drive device 26) and is configured to place the extrusion element 12 in a linear movement based on the driven rotational movement. Exemplarily, the drive element 17 has teeth at its outer periphery. In addition, the drive element 17 has a central through hole, at which there is an internal thread. The drive element 17 can also be called a spindle nut 19, a gear, or a spindle nut gear. The spindle 18 of the extrusion element 12 runs through the central through hole. The spindle 18 is in engagement with the internal thread of the drive element 17 with its external thread, so that the spindle 18 is placed in a linear movement when the drive element 17 rotates.

[0057] The drive device 51 further comprises a coupling gear 45, through which the drive element 17 is coupled to the drive instrument 26. The coupling gear 45 is in engagement with the teeth of the drive element 17. Exemplarily, the coupling gear 45 has a smaller diameter than the drive element 17. Exemplarily, the coupling gear 45 is arranged below the drive element 17 along the z direction. The coupling gear 45 is coupled to the driven shaft 46 of the driven interface 27 in a rotationally fixed manner. Exemplarily, the coupling gear 45 is arranged coaxially with the driven shaft 46. The driven shaft 46 is oriented parallel to the x direction. The driven shaft 46 is coupled or can be coupled to the drive instrument 26, in particular to the drive interface 27 via the driven interface 28 and can be placed in the driven rotational movement by the driving rotational movement provided by the driving instrument 26. The driven rotational movement is transmitted to the drive element 17 via the coupling gear 45.

[0058] The liquid container squeezing machine 10, 20 comprises an operating element 47, by which the drive of the squeezing element 12 can be controlled, and thus the outflow of liquid from the liquid container 2 can be controlled. The operating element 47 is in particular implemented as a button, preferably as a trigger button or a pistol trigger. The operating element 47 is arranged at the carrying handle 4, in particular at the upper end of the carrying handle 4. The operating element 47 can be operated with the first hand of the user, that is, in the following state, in which the user grasps the carrying handle 4 with the first hand. The operating element 47 is communicatively coupled to the electric drive 16, for example, by the control unit 48, so that the operation of the operating element 47 causes the squeezing element 12 to be driven by the electric drive 16.

[0059] The liquid container pressing machine 10, 20, in particular the additional device 8, is configured to selectively place the pressing element 12 in a locked position and a released position. In the locked position, the pressing element 12 is located farther in the (negative) x direction than in the released position. In the locked position, the pressing element 12 is in particular in the x region of the receiving portion 1 and / or in the receiving space 37 of the liquid container 2. In the released position, the pressing element 12 is preferably not in the x region of the receiving portion 1 and / or in the receiving space 37.

[0060] The liquid container pressing machine 10, 20, in particular the additional device 8, has a drive device 51 to place the pressing element 12 in the locked position. To place the pressing element 12 in the locked position, the pressing element 12 is moved in the forward direction (that is, the negative x direction). In addition, the liquid container pressing machine 10, 20, in particular the additional device 8, has a reset mechanism 14 to place the pressing element 12 in the released position. To place the pressing element 12 in the released position, the pressing element 12 is moved in the backward direction (that is, in the positive x direction).

[0061] The restoring mechanism 14 can be disengaged by actuating the actuating element 6 . Figures 11 to 13 Different possibilities are shown of how the restoring mechanism 14 can be coupled to the actuating element 6 and / or how the restoring mechanism 14 can be implemented.

[0062] Fig.11 A first design is shown, in which the reset mechanism 14 is coupled to the operating element 6. Preferably, the reset mechanism 14 is mechanically coupled to the operating element 6, so that the reset mechanism 14 is mechanically disengaged by the operating element 6. The reset mechanism 14 can also be referred to as a reset device. Alternatively, the operating element 6 and the reset mechanism 14 can also be communicatively coupled. The operating element 6 is, for example, configured to send a control signal and the reset mechanism 14 is configured to receive a control signal and disengage based on the control signal in order to cause the pressing element 12 to be placed in the release position.

[0063] By way of example, the reset mechanism 14 (when it is released) causes the coupling between the drive element 17 and the pressing element 12 to be released and the pressing element 12 to be placed in the release position, in particular by means of the spring element 15. Here, the reset mechanism 14 acts (in particular mechanically) on the drive device 51 in order to release the coupling between the drive element 17 and the pressing element 12.

[0064] Fig.11Furthermore, the electric drive 16 and the control unit 48 are shown, which are components of the liquid container extruder 10, 20 and are arranged in particular on the drive device 26. The control unit 48 controls the electric drive 16 so that the electric drive 16 drives the drive device 51 and thus causes the extrusion element 12 to perform an advance movement. Figure 1 In the embodiment shown in , the resetting mechanism 14 is expediently independent of the control unit 48 and / or the electric drive 16. In order to bring the pressing element 12 into the release position, the control unit 48 and / or the electric drive 16 are preferably unnecessary.

[0065] Fig.12 A second design is shown, in which the reset mechanism 14 is communicatively connected to the operating element 6. Here, the reset mechanism 14 is formed by an electric drive 16, a drive device 51 and a control unit 48. The operating element 6 is connected to the control unit 48 by wire or wirelessly and when the operating element 6 is operated (by sending a control signal), the control unit 48 controls the electric drive 16 as follows, so that the electric drive 16 drives the drive device 51 as follows, so that the pressing element 12 is placed in the release position by the drive device 51. In other words, the reset mechanism 14 includes an electric drive 16, which is configured to place the pressing element 12 in the release position.

[0066] Fig.13 A third embodiment is shown, which corresponds to the second embodiment in that the pressing element 12 is moved into the release position by the electric drive 16. In the third embodiment, the battery section 49 of the drive device 26, for example an AC battery module, is designed as a communication device and is configured to provide wireless communication, for example Bluetooth communication, to the operating element 6. When the operating element 6 is actuated, a wireless communication (of a control signal) takes place from the operating element 6 to the battery section 49, which in response communicates with the control unit 48 in order to cause (by means of a control command) the pressing element 12 to be moved into the release position by the electric drive 16 and the drive device 51.

[0067] Suitably, the drive device 26, in particular the electric drive 16, provides a driving rotational movement in a first rotational direction to place the extrusion element 12 in an advancing movement. In addition, the drive device 26, in particular the electric drive 16, provides a driving rotational movement in a second rotational direction opposite to the first rotational direction to move the extrusion element 12 in a backward direction.

[0068] The carrying handle 4 and the stabilizing handle 5 will be discussed in more detail below. The carrying handle 4 and the stabilizing handle 5 are two different handles. The stabilizing handle 5 is present in addition to the carrying handle 4. The stabilizing handle 5 is arranged at a distance from the carrying handle 4. The stabilizing handle 5 is not the carrying handle 4.

[0069] The carrying handle 4 is exemplarily a part of the vertical section 24, in particular the drive device 26. The carrying handle 4 is exemplarily designed as a pistol grip. The longitudinal axis of the carrying handle 4 is oriented vertically, in particular in the z direction or in the xz direction. The carrying handle 4 can be grasped around its longitudinal axis. The carrying handle 4 is arranged in the rear area of ​​the liquid container extruder 10, 20. The carrying handle 4 is preferably at least 8 cm long (in the direction of its longitudinal axis).

[0070] Exemplarily, the stabilizing handle 5 is arranged farther in the front (that is, farther in the negative x-direction) than the carrying handle 4. Exemplarily, the stabilizing handle 5 is arranged in the longitudinal direction of the liquid container press 10, 20, in particular the auxiliary device 8 (that is, in the x-direction) between the carrying handle 4 and the front end 11 of the receiving part 1, in particular the front end of the liquid container press 10, 20. The stabilizing handle 5 is arranged in particular in the area in front of the liquid container press 10, 20, in particular the auxiliary device 8.

[0071] By way of example, the stabilizing handle 5 is arranged in the longitudinal direction of the liquid container press 10, 20, in particular the additional device 8, that is to say in the x-direction, in the same longitudinal region as the receptacle 1. The stabilizing handle 5 occupies in particular the same x-region as the receptacle 1 and / or the liquid container 2. Preferably, the stabilizing handle 5 is only in the same x-region as the receptacle 1 and / or the liquid container 2.

[0072] The stabilizing handle 5 is arranged at the horizontal section 23, in particular the rod section 25. The stabilizing handle 5 is arranged at the bottom of the rod section 25 by way of example. The stabilizing handle 5 at least partially surrounds the rod section 25. The stabilizing handle 5 is exemplarily designed as a front rod handle. The stabilizing handle 5 is expediently designed in an elongated manner and is oriented with its longitudinal axis parallel to the x-direction. The stabilizing handle 5 can be grasped around its longitudinal axis. The stabilizing handle 5 has, by way of example, the basic shape of a hollow cylindrical section (that is to say, in particular a hollow cylinder), in which part of the periphery is omitted. The stabilizing handle 5 is expediently at least 8 cm long (in the x-direction).

[0073] Preferably, the stabilizing handle 5 has an operating element 6. Exemplarily, the stabilizing handle 5 is displaceable for actuation in the longitudinal direction of the liquid container extruder 10, in particular the auxiliary device 8, that is, in the x direction. The stabilizing handle 5 is mounted on the shaft section 25 in a linearly movable manner in particular. The liquid container extruder 10, in particular the auxiliary device 8, comprises a linear bearing, which provides a linearly movable bearing of the stabilizing handle 5 on the shaft section 25.

[0074] The stabilizing handle 5 can be selectively placed in an actuated position or an un-actuated position by manipulation by the user. In the actuated position, the stabilizing handle 5 is preferably located farther in the positive x-direction than in the un-actuated position. In the actuated position, the stabilizing handle 5 is in particular closer to the carrying handle 4 and / or closer to the driven interface 28 than in the un-actuated position. In order to place the stabilizing handle 5 in the actuated position, the stabilizing handle 5 is pulled backwards (that is, in the backward direction) with the second hand of the user, in particular while the user is grasping the carrying handle 4 with the first hand. Exemplarily, the stabilizing handle 5 is pre-tensioned, in particular in the negative x-direction, so that the stabilizing handle 5 itself is pressed into the un-actuated position (when the user, for example, releases the stabilizing handle 5). In response to the actuated position of the stabilizing handle 5, the reset mechanism 14 causes the pressing element 12 to be placed in the release position.

[0075] Preferably, in response to the unactuated position of the stabilizing handle 5 , the drive element 17 is coupled to the pressing element 12 , so that the pressing element 12 can be driven by the drive element 17 in order to perform a forward movement.

[0076] As already mentioned above, in the second embodiment of the operating element 6 (see Figure 5 ) can be arranged in the region of the stabilizing handle 5. In this case, the stabilizing handle 5 is preferably not an operating element 6. Figure 5 , the operating element 6 can be arranged, for example, next to the stabilizing handle 5. The operating element 6 is arranged close enough to the stabilizing handle 5 so that it can be operated by the user's hand, in particular the second hand, while the user is holding the stabilizing handle 5 with his hand, in particular the second hand. The operating element 6 is exemplarily implemented as a button. According to a possible embodiment, the operating element 6 (in particular implemented as a button) can be arranged on the stabilizing handle 5. In this case, the operating element 6 is also arranged in the area of ​​the stabilizing handle 5.

[0077] The following should be referenced Figures 6 to 10 An exemplary mechanical design of the restoring mechanism 14 is discussed in more detail.

[0078] As mentioned above, the squeezing mechanism 3 includes a squeezing element 12 for squeezing and locking the liquid container 2. The reset mechanism 14 is configured to automatically place the squeezing element 12 in a release position in response to the operation of the operating element 6, in which the locking of the liquid container 2 is disengaged. The reset mechanism 14 is particularly configured to provide the reset force necessary for placing the squeezing element 12 in the release position. In other words, the reset force does not need to be provided by the user. In particular, the user does not need to manually move the squeezing element 12 to the release position.

[0079] As in Figure 6As shown in , the reset mechanism 14 exemplarily comprises a spring element 15, whose spring force is used to place the pressing element 12 in the release position. The spring force of the spring element 15 serves as a reset force, which is necessary for placing the pressing element 12 in the release position. Exemplarily, the spring element 15 is a helical spring. The spring element 15 is especially implemented as a compression spring. The spring element 15 is oriented with its longitudinal axis parallel to the x-direction. Exemplarily, the spring element 15 is arranged parallel to the rod section 43, in particular vertically on the rod section 43. The spring element 15 is especially arranged in the longitudinal section 44 behind the auxiliary instrument 8.

[0080] Exemplarily, the pressing element 12 has a spring support element 52, on which the spring element 15 is supported (especially when the pressing element 12 is in the locked position). The spring support element 52 is exemplarily arranged at the rod section 43, especially at its rear end (that is, the end furthest to the rear in the positive x-direction). The spring support element 52 extends radially from the rod section 43, especially vertically upwards. The rod section 43 is especially the spindle 18.

[0081] The liquid container extruder 10, 20, in particular the additional instrument 8, has a support structure 53, relative to which the extrusion element 12 can move. Exemplarily, the support structure 53 presents the housing of the additional instrument 8. The support structure 53 includes a support section 54, on which a spring element 15 is supported. The spring element 15 is exemplarily arranged between the support element 52 and the support section 54. When the extrusion element 12 moves in the forward direction (that is, in the negative x direction), the support element 52 moves together with the extrusion element 12 in the direction toward the support section 54, so that the spring element 15 is compressed between the support section 54 and the support element 52. When the extrusion element 12 is decoupled from the drive element 17 (by disengaging the reset mechanism 14), the spring force acting on the support element 52 causes the extrusion element 12 to move in the backward direction (that is, in the positive x direction) to the release position.

[0082] As mentioned above, the liquid container extruder 10, 20, in particular the auxiliary device 8, comprises a drive element 17 coupled to the extrusion element 12 for driving the extrusion element 12. The reset mechanism 14 is designed to release the coupling between the drive element 17 and the extrusion element 12 in response to the actuation of the actuation element 6.

[0083] The drive element 17 is for example Fig.10. As already mentioned above, the drive element 17 is exemplarily implemented as a spindle nut 19. Exemplarily, the spindle nut 19 comprises at least one coupling element 21. In response to the actuation of the actuating element 6, the at least one coupling element 21 can be moved from a coupling position into an uncoupling position, in which the coupling element 21 is engaged with the external thread of the spindle 18, and in which the coupling element 21 is not engaged with the external thread of the spindle 18.

[0084] Fig.10 An exemplary embodiment is shown, in which the spindle nut 19 comprises a plurality of coupling elements 21 (here, three coupling elements 21 are exemplarily shown). Each coupling element 21 is exemplarily implemented as a clip. The spindle nut 19 has a gear body 55, on which each coupling element 21 is arranged. Each coupling element 21 is fixed to the gear body 55 in such a way that each coupling element 21 rotates together with the spindle nut 19 when the spindle nut is set into a rotational motion for driving the extrusion element 12.

[0085] Each coupling element 21 has an internal thread section 56. The internal thread sections 56 together form the internal thread of the spindle nut 19. Each internal thread section 56 is in engagement with the external thread of the spindle 18 in the coupled position. In addition, each internal thread section 56 is not in engagement with the external thread of the spindle 18 in the decoupled position.

[0086] Each coupling element 21 is mounted on the gear body 55 so as to be pivotable about a respective pivot axis 57. By pivoting about a respective pivot axis 57, each coupling element 21 can be selectively placed in a coupled position or an uncoupled position.

[0087] Each coupling element 21 has a guide section 58, which is exemplarily implemented as a guide slot. Exemplarily, a corresponding engagement element 59 is grasped in each guide section 58, which is suitably implemented as a pin. The movement of the corresponding engagement element 59 results in a swing of each coupling element 21. Suitably, the engagement element 59 is a component of a decoupling element 61. The decoupling element 61 is implemented as a gear and can also be referred to as a decoupling gear. The decoupling element 61 is exemplarily arranged coaxially with the spindle nut 19. Exemplarily, the decoupling element 61 is arranged directly next to the spindle nut 19 in the x direction. The decoupling element 61 has a through hole, for example a central bore, through which the spindle 18 runs.

[0088] The decoupling element 61 can be moved into an unlocking rotational movement relative to the spindle nut 19 in order to move the engagement element 59 so that the coupling element 21 is pivoted into the decoupling position.

[0089] By way of example, each coupling element 21 is prestressed by a spring, so that each coupling element 21 itself is pressed into the coupled position.

[0090] The operating element 6 is coupled to the coupling element 21 as follows, so that placing the operating element 6 in the operated position causes the coupling element 21 to be placed in the uncoupled position. In addition, placing the operating element 6 in the unoperated position causes the coupling element 21 to be placed in the coupled position.

[0091] Exemplarily, the operating element 6 and the decoupling element 61 are mechanically coupled via a coupling assembly as follows, so that the movement of the operating element 6 to the operated position, in particular the linear movement, is mechanically converted into a rotational movement of the decoupling element 61 relative to the spindle nut 19, so that the coupling element 21 is placed in the decoupling position.

[0092] According to an alternative design, the operating element 6 is not mechanically connected to the reset mechanism 14 but is communicatively coupled. For example, the operation of the operating element 6 is converted into an electrical signal by an electrical switch and / or a button, and the actuator at the spindle nut 19 and / or the spindle 18 is controlled by the electrical signal, in particular to promote the decoupling between the spindle nut 19 and the spindle 18.

[0093] The coupling assembly exemplarily comprises a first coupling section 62 and a second coupling section 63. The first coupling section 62 is placed at the stabilizing handle 5, in particular in the x-direction. The first coupling section 62 moves with the stabilizing handle 5 in the x-direction when the stabilizing handle 5 moves linearly. The first coupling section 62 has an inclined surface 64, on which the second coupling section 63 is abutted. The inclined surface 64 is exemplarily oriented perpendicular to the xz direction. By abutting at the inclined surface 64, the second coupling section 63 is placed in a movement with an upward z component, in particular a vertical movement, when the first coupling section 62 (along the positive x-direction) moves backward. The second coupling section 63 is in engagement with the teeth of the decoupling element 61, so that the movement of the second coupling section 63 is converted into a rotational movement of the decoupling element 61, and the rotational movement causes the coupling element 21 to be placed in the decoupling position. The second coupling section 63 is particularly implemented as a stop pawl.

[0094] The liquid container press 10, 20, in particular the auxiliary device 8, advantageously has an actuating element return spring 65, which presses the actuating element 6, in particular the stabilizing handle 5, into the unactuated position. The actuating element return spring 65 acts, for example, on the first coupling section 62, i.e. in the forward direction, i.e. in the negative x direction.

[0095] In addition, the liquid container extruder 10, in particular the additional device 8, preferably comprises a coupling section return spring 66, which acts on the second coupling section 63 and expediently presses the second coupling section 63 in the downward direction. The coupling section return spring 66 in particular presses the second coupling section 63 into a coupling section release position, in which the second coupling section 63 is not in engagement with the decoupling element 61.

[0096] When the user no longer actuates the stabilizing handle 5 with his hand, in particular the second hand, that is, in particular no longer exerts force on the stabilizing handle 5 in the negative x direction, the stabilizing handle 5 is moved from the actuated position to the non-actuated position by the actuating element return spring 65. When the stabilizing handle 5 is in the non-actuated position, the inclined surface 64 no longer presses the second coupling section 63 upward, so that the second coupling section 63 is moved downward into the coupling section release position by the coupling section return spring 66. In the coupling section release position, the second coupling section 63 does not exert any force on the decoupling element 61, so that the coupling element 21 is placed in the coupling position due to its spring prestressing.

[0097] Optionally, in the following state, in which the locking of the liquid container 2 is disengaged, the operating element 6 can be operated by the user in order to establish the locking of the liquid container 2. For example, when the operating element 6 is operated (by means of a control signal), the control unit 48 controls the electric drive 16 as follows, so that the electric drive 16 drives the drive device 51 as follows, so that the pressing element 12 is placed in the locked position by the drive device 51. For example, the control unit 48 recognizes that the pressing element 12 is in the release position and based on the recognition, causes the pressing element 12 to be placed in the locked position when the operating element 6 is operated. Exemplarily, the pressing element 12 can be placed alternately in the release position and the locked position by the operation of the operating element 6.

[0098] Furthermore, it is possible that by actuating the actuating element 6 in the forward direction (that is, in the negative x direction), a movement of the pressing element 12 in the forward direction is initiated until the pressing element 12 locks the liquid container 2. For example, after the partially emptied scroll is inserted, the spindle 18 is moved forward after actuation of the stabilizing handle 5 (for example, by moving forward) until the pressing head 42 is in force engagement with the scroll.

[0099] Then, you should refer to Fig.14 and 15 An alternative design is discussed, in which the liquid container pressing machine 10, 20, in particular the auxiliary device 8, comprises a resting device 22. The resting device 22 can preferably be released by actuating the actuating element 6. The resting device 22 is configured to rest the liquid container 2 relative to the receiving portion 1, so as to facilitate the removal of the liquid container 2 from the receiving portion 1.

[0100] Exemplarily, the resting device 22 comprises a resting element 67, which is arranged in particular in or on the receiving portion bottom 29, so that the resting element 67 is located below the inserted liquid container 2. The resting element 67 is expediently configured to apply a resting force acting upward to the liquid container 2, in particular to the rear body section 41. Exemplarily, the resting element 67 is implemented as a spring element or is loaded on the receiving portion 1 by a spring element in order to provide the resting force as a spring force.

[0101] Exemplarily, the resting device 22 further has a restraining element 68, which is coupled to the operating element 6, in particular the stabilizing handle 5, and prevents the resting element 67 from exerting a resting force on the liquid container 2 as long as the operating element 6 is in the unoperated position. The restraining element 68 is exemplarily implemented as a hook, which is coupled to the operating element 6 via the first coupling section 62 and is thus guided along the x direction together with the operating element 6. In the unoperated position of the operating element 6, the restraining element 68 is in engagement with the resting element 67, so that the resting element 67 cannot move upward. In the operated position of the operating element 6, the restraining element 68 is not in engagement with the resting element 67, so that the restraining element 68 does not prevent the resting element 67 from moving upward.

[0102] You should then refer to Fig.16 The following will describe a method for operating a liquid container press 10 , 20 , in particular an auxiliary device 8 . At the beginning of the method, a liquid container 2 is already placed in the receptacle 1 .

[0103] Expediently, before the first step S1 , the auxiliary device 8 is attached to the drive device 26 in order to form the liquid container extruder 10 , 20 .

[0104] The method comprises a first step S1, in which the squeezing mechanism 3 is actuated to cause the liquid to flow out of the liquid container 2. Exemplarily, in step S1, the operating element 47 is actuated to cause the electric drive 16 to provide a driving rotational movement, based on which the drive element 17 is set in a rotational movement, thereby setting the spindle 18 in a linear forward movement, so that the squeezing element 12 moves the pressing section 36 in the forward direction (that is, in the negative x direction) in order to cause the liquid to flow out of the liquid container 2. Expediently, in the first step S1, the user grasps the liquid container squeezing machine 10, 20 with both hands, that is, grasps the carrying handle 4 with the first hand and grasps the stabilizing handle 5 with the second hand. The squeezing element 12, in particular the squeezing head 42, is located in the receiving space 37, so that the liquid container 2 is locked in the receiving portion 1 and cannot be removed.

[0105] The method then continues with a second step S2, in which the actuating element 6 is actuated to cause the liquid container 2 to be released by the locking of the pressing element 12. Exemplarily, the user moves his hand, in particular the second hand with which the user grasps the stabilizing handle 5, in the retreat direction (that is, in the positive x direction) in order to bring the stabilizing handle 5 from the unactuated position into the actuated position. This causes the restoring mechanism 14 to move the pressing element 12 backward in the retreat direction, so that the pressing element 12 is no longer in the receiving space 37 and the liquid container 2 is no longer locked in the receiving portion by the pressing element 12. Expediently, the actuation of the actuating element 6 causes an automatic (and in particular complete) process of bringing the pressing element 12 into the release position.

[0106] The method continues with step S3, in which the unlocked liquid container 2 is manually removed from the receptacle 1 by the user. The user preferably does not perform any further actions between the actuation of the actuating element 6 and the manual removal of the liquid container 2. In particular, the user does not have to manually move the pressing element 12 into the release position.

[0107] The method continues with an optional step S4, in which the user inserts a further liquid container 2 into the receptacle. By means of actuation of the operating element 47 (or, if the liquid container pressing machine 10, 20, in particular the additional device 8, is configured accordingly, by means of actuation of the operating element 6), the pressing element 12 is moved in the forward direction based on the drive rotational movement provided by the electric drive 16, so that the pressing element 12 is moved into the receiving space 37, in order to lock the further liquid container 2 in the receptacle 1 and to press the pressing section 36 in the forward direction, in order to cause the liquid to flow out of the further liquid container 2.

[0108] The user can, for example, complete the desired seam by the outflow of liquid with the help of the described liquid container squeezer 10, 20. If the liquid container 2 is exhausted or the color is desired to be changed, the user pulls the stabilizing handle 5 (also known as the ejection handle) toward himself (zu sich) and backward. Here, the spindle nut 19 (also known as the spindle coupling) is opened by mechanical coupling. As long as the spindle coupling is opened, the spindle 18 is reset to the release position by means of the spring force of the spring element 15 and the liquid container 2 is released for removal. Now, the user can take it out by gripping the liquid container 2. Preferably, when gripping the stabilizing handle 5, it is reset to the unoperated position by means of the spring force (of the operating element return spring) and the spindle coupling is closed. Now, the user can place a new liquid container 2 into the liquid container squeezer 10, 20 and continue its working process.
