DETAILED DESCRIPTION
(28) FIG. 1 shows a first embodiment in the storage state with a sealed cartridge 1 with two containers 2. The cartridge 1 is shown here in a storage state and is sealingly closed by a closure element 3, here a closure plug. The closure element 3 comprises a connecting element 4, which is already attached to the closure element 3 in the delivery state and has a positioning tongue 5, the function of which is explained in greater detail in WO 2013/026 717 A1 and is referenced in this connection. Furthermore, the closure element 3 has a circumferential ring 3a provided with a corrugated surface, which facilitates a manual twisting of the closure element 3 relative to the cartridge 1.
(29) Several predetermined breaking points 6 are provided on the connecting element 4, by means of which the connecting element 4 is connected with the cartridge 1 in such a way that it cannot be removed without being destroyed. Stated more precisely, the connecting element 4 is connected with the front surface of a collar-shaped connecting part 7 of the cartridge 1 by way of the predetermined breaking points 6. The connecting part 7 serves for the accommodation of a closure element 3 or of a corresponding accessory 11 and has, furthermore, the symbols 8a, 8b and 8c, which indicate the direction of rotation (arrow 8c) for the opening (opened lock 8b) and for the closing (closed lock 8a).
(30) In one preferred configuration, the connecting element 4 and the positioning tongue 5 have the same coding, such as the same color, for example. A specific symbol on the connecting element 4 and the positioning tongue 5 is also conceivable.
(31) FIG. 2 shows how the closure element 3 is detached from the cartridge 1. While the bulk of the connecting element 4 remains on the closure element 3, connecting points 4a were detached at the predetermined breaking points 6, which [connecting points] remain on the cartridge 1 or the front surface of a collar-shaped connecting part 7, respectively. These connecting points 4a preferably have a coding in the form of a color, which preferably stands out in clear contrast to the cartridge color.
(32) If the connecting points 4a and the connecting element 4 have the same coding, then a user can, even after the detachment of the closure element 3 from the cartridge 1, determine, both rapidly and free of doubt, which closure element 3 sealingly closes the cartridge 1. A user can thus be prevented from placing a non-fitting closure element 3 on the cartridge 1, which would impair the tightness of the closure. Through the sealing of the cartridge 1 with another closure element 3, a contamination of the components stored in the cartridge 1 is additionally prevented.
(33) FIG. 3 shows the cartridge 1 in accordance with FIG. 2 without a closure element 3. The precise configuration of the collar-shaped connecting part 7, which encloses the outlets 9 of the container 2 and has an internal thread 10, can be seen in this figure.
(34) FIG. 4 shows the cartridge 1 as described above with the corresponding accessory 11, here a mixer, in its placed-on position. The mixer 11 comprises, like the closure element 3, a positioning tongue 5, which has the same coding, particularly the same color, as the connecting element 4 and the connecting points 4a. By that means, it is particularly simple for a user to place the fitting mixer 11 on the cartridge 1, so that errors in application are avoided. The coding can also, additionally or alternatively, be applied to the accessory housing 12 or to the mixing element (not depicted), to the mixer connecting part, and/or to a union nut, and even bear a symbol that permits a coordination of the fitting parts of the application system instead of a color.
(35) FIG. 5 shows a second configuration of an application system in the storage state with a sealed cartridge 1. The closure element 3 here comprises a connecting element 3 configured as a band that can be torn off with a flexible tab 13, which increases the engagement surface for a manual removal of the connecting element 4 configured as a band from the closure element 3 and thus represents a particularly user-friendly configuration. It is preferred if the connecting element 4 and the positioning tongue 5 configured as a band have the same coding, particularly the same color. The coding can also be applied, additionally or alternatively, to the accessory housing 12 or to the mixing element (not depicted), to the mixer connecting part, and/or to a union nut, and even bear a symbol that permits a coordination of the fitting parts of the application system instead of a color. In the variant depicted here, it is necessary to remove the connecting element 4 configured as a band from the cartridge 1 before the detachment of the closure element 3.
(36) A band 13 detached from the closure element 3 is depicted in FIG. 6. In this state, the closure element 3 is detachable from the cartridge 1 through the relative rotation of the closure element 3 relative to the cartridge 1. The corrugated ring 3a is released through the detachment of the band 13, and a user can remove the closure element 3 through rotation relative to the cartridge 1. A marking 3b is preferably provided on the ring 3a which, in the interaction with the symbols 8a and 8b, indicates a sealed cartridge 1 (symbol 8a) or an opened cartridge 1 (symbol 8b).
(37) FIG. 7 shows an additional configuration of a coding over a portion of the connecting element 4, which remains on the cartridge 1 upon the detachment of the closure element 3. The connecting element 4 is constructed in the embodiment depicted in FIG. 7 as a circumferential ring on the internal edge of the collar-shaped connecting part 7. The coding is preferably achieved by a corresponding color of the connecting element 4 and of the positioning tongue 5. Since the connecting element 4 is, in the second configuration, positioned on the side of the closure element 3 facing the cartridge 1, this cannot be seen in FIGS. 5 and 6. On the other hand, the coding can also be applied, either additionally or alternatively, to the accessory housing 12 or to the mixing element (not depicted), to the mixer connecting part, and/or a union nut and even bear a symbol that permits a coordination of the fitting parts of the application system instead of a color.
(38) FIG. 8 illustrates the system in accordance with FIG. 7 with the mixer 11 placed on. The connecting element 4 can also be seen in this state, so that the coding can be seen, even after the placement of a corresponding accessory 11 on the cartridge 1. By that means, it can be checked, even when the corresponding accessory 11 has already been placed on, whether the codings of the cartridge 1 and the accessory 11 are in agreement, which can, in this case, particularly involve the corresponding color of the connecting element 4 and of the positioning tongue 5.
(39) FIG. 9 shows a third configuration of a storage state of the application system. In this case, the connecting element 4 is connected with the ring 3a of the closure element 3 by way of predetermined breaking points 6. The symbols 8a, 8b and 8c previously attached to the cartridge 1 are now implemented as recesses in the connecting element 4. The symbols 8a, 8b and 8c, the surface of the cartridge 1 or of its connecting part 7, respectively, can be seen through the recesses forming. The connecting element 4 is, furthermore, attached to the connecting part 7 of the cartridge 1, such as by fusing, for example.
(40) FIG. 10 shows the configuration in accordance with FIG. 9 after the detachment of the closure element 3 from the cartridge 1. The connecting element 4 remains with one part on the cartridge 1 and is sheared off from the closure element 3 at the predetermined breaking points 6. In particular, the connecting element 4 and the positioning tongue 5 have this color, which permits a coding and thereby an assignment of fitting parts of the application system. On the other hand, the coding can also be applied, additionally or alternatively, to the accessory housing 12 or to the mixing element (not depicted), to the mixer connecting part, and/or to a union nut, and even bear a symbol that permits a coordination of the fitting parts of the application system instead of a color.
(41) FIG. 11 illustrates a connecting or placement of a corresponding accessory 11 with the cartridge 1 and connecting element 4 attached to it. A coding is achieved through an agreement in the color of the positioning tongue 5 and the connecting element 4.
(42) FIG. 12 shows the embodiment in accordance with FIG. 11 with the corresponding accessory 11 completely placed on. Since both the positioning tongue 5 as well as the connecting element 4 can be seen in a corresponding accessory 11 connected with the cartridge, a check can be performed in order to determine whether a fitting corresponding accessory 11 has been placed on, whereby application errors are avoided.
(43) FIG. 13 shows a fourth embodiment of an application system in the storage state with a sealed cartridge 1. The connecting element 4 is configured hexagonally here and is connected with the closure element 3 by way of predetermined breaking points 6. On the other hand, both the positioning tongue 5 as well as the connecting element 4 can be of the same color, which permits a coordination of the fitting elements of the application system. On the other hand, the coding can also be applied, additionally or alternatively, to the accessory housing 12 or to the mixing element (not depicted), to the mixer connecting part, and/or to a union nut, and even bear a symbol that permits a coordination of the fitting parts of the application system instead of a color.
(44) In the fourth embodiment, if the closure element 3 is detached from the cartridge 1, the connecting element 4 breaks off from the closure element 3 at the predetermined breaking points 6 and remains on the cartridge 1, as can be seen in FIG. 14.
(45) FIG. 15 and FIG. 16 show the connecting of a corresponding accessory 11 and, on the other hand, a mixer, with the cartridge 1 (FIG. 15), as well as the placed-on state (FIG. 16). For that purpose, the closure element 3 is detached from the cartridge, so that it can be used in a state of use, such as to dispense the components stored in it, for example. In order for a user to be able to assign the fitting accessory 11 to the cartridge 1, the positioning tongue 5 and the connecting element 4 are configured with the same coding, particularly of the same color.
(46) FIG. 17 shows an exploded diagram of an application system in accordance with a fifth embodiment.
(47) In this embodiment, the closure element 3 is configured in a three-part manner and comprises a union element 14, here a cap, a fastening ring 15, and a closure insert 16. The fastening ring 15 comprises an external thread 10a, which can engage with the internal thread of the connecting part 7 of the cartridge 1 and can create a connection between the closure element 3 and the cartridge 1. Bearing pins 3c, which can be plugged into the outlets 9 of the container 2 of the cartridge 1 and thus sealingly close the same, are provided on the closure insert 16.
(48) While the closure elements 3 of the first four embodiments of the application system similarly have a fastening ring 15 and a closure insert 16, the closure plugs, particularly those shown in FIG. 17, additionally have a union element 14.
(49) The union element 14 here is connected with the connecting element 4 by way of predetermined breaking points 6 and can be pulled over a fastening ring 15 of the closure element 3, as indicated in FIG. 17 and as occurs in FIGS. 18 and 19. By that means, the closure elements 3, which are present and known per se, can be used and supplemented in order to produce a separately producible union element 14 and to thus form parts of the application system in accordance with the disclosure. In other words, through the provision of the union element 14, an existing application system can be easily configured in accordance with the disclosure and improved.
(50) The connecting element 4 of the fifth embodiment is, similarly to the case in the third embodiment in accordance with FIGS. 9 to 12, provided with recesses, which form the symbols 8a, 8b and 8c (FIG. 18). The assembly in accordance with FIG. 18 represents a possible storage state.
(51) The application system in accordance with FIG. 17 therefore shows one possible delivery state of an application system in accordance with the disclosure before the joining of the union element 14, closure element 3 and cartridge 1.
(52) FIG. 19 shows the detachment of the closure element 3 from the cartridge 1, whereby the connecting element 4 breaks off from the closure element 3 at the predetermined breaking points 6 and remains on the cartridge 1.
(53) FIG. 20 and FIG. 21 show the placement and the connecting of a corresponding accessory 11 on or with the cartridge 1 (FIG. 20) and the placed-on state (FIG. 21), respectively. The positioning tongue 5 and the connecting element 4 are preferably designed with the same coding, particularly the same color. On the other hand, the coding can also be applied, additionally or alternatively, to the accessory housing 12 or to the mixing element (not depicted), to the mixer connecting part, and/or to a union nut, and even bear a symbol that permits a coordination of the fitting parts of the application system instead of a color.
(54) FIGS. 22 and 23 each show a variant of the application system in accordance with the disclosure in accordance with the fifth embodiment, in which a depression 17 is provided in the union element 14.
(55) The depression 17 can, in the variant depicted in FIG. 22, be sealed by a pull tab 18, whereby the pull tab 18 is preferably adhered to the union element 14 on its edges.
(56) A foldable package insert 19, an RFID chip, a transponder, and/or a bonus or payback token or the like can be accommodated in the depression 17, for example. The accommodation of a foldable package insert 19, as depicted here, has the advantage, in particular, that the package insert 19 can contain information on the use of the cartridge 1 in accordance with regulations and/or the contents. But the package insert 19 here is not enclosed in the packaging (not depicted) of the cartridge 1, as is usually the case, but is instead connected with the application system, so that a user can, in the event of unclarity about use, inform himself quickly and without complication. Furthermore, the package insert 19 is readily available, even after the unpacking of the application system and the disposal of the packaging material. A package insert 19 accommodated in the depression 17 is also of importance for a manufacturer of the application system and/or of the components stored therein, in order for the same to comply with the requirements for the provision of verifiable legal information on the application system and/or the components stored therein.
(57) FIG. 23 shows an alternative to FIG. 22, in which, instead of a package insert 19, the recess 17 is used to present production-specific information 20 and/or test seal 21.
(58) FIG. 24 shows a sixth embodiment of the application system in accordance with the disclosure. The connecting element 4 here is designed in a single piece with the cartridge 1 as a bar protruding over the connecting part 7. This bar can be accommodated on the closure element 3 by means of a latching recess 22 provided on the ring 3a, if the closure element 3 is connected with the cartridge 3 (FIG. 25). The latching recess 22 is designed here through the omission of a groove on the external edge of the ring 3a.
(59) FIG. 25 shows the sixth embodiment of the application system in accordance with the disclosure, whereby the closure element 3 is connected with the cartridge 1. In particular, it can be seen in the detailed view that the connecting element 4 constructed as a bar is accommodated in the recess 22. If the closure element 3 detaches from this through rotation relative to the cartridge 1, then a shearing off of the connecting element 4 constructed as a bar comes about, so that a first-time opening of the cartridge 1 can be seen. Since the part of the connecting element 4 positioned higher than the connecting part 7 remains on the cartridge 1, however, a coordination of fitting accessories 11 is possible, even after the detachment of the closure element 3.
(60) FIG. 26 shows a closure element 3 of a seventh embodiment of an application system in accordance with the disclosure. In comparison with the above-described configurations of the closure element 3, the connecting element 4 is configured as a guide element and is connected with the positioning tongue 5 by way of a predetermined breaking point 6.
(61) FIG. 27 shows a cartridge 1 of a seventh embodiment of an application system in accordance with the disclosure. A guide channel 23, which can accommodate the connecting element 4 configured as a guide element (FIG. 28) and is, in particular, axially secured by engagement in the guide channel 23, is provided between the containers 2.
(62) In FIG. 28, the closure element 3 in accordance with FIG. 26 is connected with the cartridge 1 in accordance with FIG. 27, so that an application system in accordance with the seventh embodiment is obtained. In particular, it can be seen in the detailed view that the guide channel 23 and the connecting element 4 configured as a guide element are thus adjusted to one another, so that the guide channel 23 accommodates the connecting element 4 and the predetermined breaking point 6 is positioned with the end of the guide channel 23 lying in the direction of the connecting part 7 at an axial level.
(63) If the closure element 3 is detached from the cartridge 1 by relative twisting, then a breaking of the predetermined breaking point 6 comes about due to the forces acting axially on it. The connecting element 4 is thereby detached from the closure element 3, through which a first-time opening of the cartridge 1 becomes visible.
(64) The connecting element 4 remains in the guide channel 23 of the cartridge 1, as shown in FIG. 29 and, because of a coding, particularly a color coding, this can indicate a fitting accessory 11. The coding can be applied to the positioning tongue 5 and, additionally or alternatively, to the accessory housing 12 or to the mixing element (not depicted), to the mixer connecting part, and/or to a union nut, and even bear a symbol that permits a coordination of the fitting parts of the application system instead of a color.
(65) FIG. 30 shows the seventh embodiment, whereby a corresponding accessory 11, here a mixer, is connected with the cartridge 1. It can be seen, in particular, that the guide channel 23 is positioned on the cartridge 1 in such a way that a placement of the corresponding accessory 11 on the cartridge 1 is not prevented. Furthermore, the guide channel 23 and the connecting element 4 accommodated therein, which is detached from the closure element 3, lie with the positioning tongue 5 in a plane between the containers 2. By that means, the codings on the connecting element 4 and on the positioning tongue 5 can easily be checked, even after the placement of the corresponding accessory 11 on the cartridge 1, so that this error can be seen and corrected, even upon the placement of a non-fitting accessory 11.
(66) FIG. 31 shows a view of the front view of the seventh embodiment shown in FIG. 30. The above-described assembly of detached connecting element 4 and positioning tongue 5 of the corresponding accessory 11 is once again made clear by this.
(67) FIG. 32 depicts an additional closure element 3 with a union element 14, a fastening ring 15, and a closure insert 16, which [closure element] thereby corresponds to the extent of a closure element 3 as depicted in FIG. 17. Thus, reference is made, in this respect, to the above description and the differences will be explained in the following.
(68) In the embodiment shown in FIG. 32, the union element 14 has several projections 24, which are provided on the inside and are evenly spaced at an interval of 120°, considered radially.
(69) The fastening ring 15 here comprises several grooves 25, which are provided on the exterior of the fastening ring 15 and are, like the projections 24, evenly spaced at an interval of 120°, considered radially. Furthermore, an opening 26 that can accommodate the closure insert 16 is provided. The fastening ring 15 also comprises a circumferential annular projection 28, which is visible in FIGS. 40 and 41.
(70) Furthermore, at least one locking tab 27 is provided on the closure insert 16, which [locking tab] firmly fastens the closure insert 16 to the fastening ring 15 in an axially secured but rotatable manner through the fact that the locking tab 27 engages behind or over the annular projection 28.
(71) Upon the assembly of the closure element 3, the closure insert 16 can first of all be inserted forward with the bearing pin 3c and the positioning tongue 5 into the opening 26 of the fastening ring 15. The positioning of the closure insert 16 with the closure element 3 is ensured by the locking tab 27, the circumferential annular projection 28, and the radial contour 29. By that means, an unintended and excessively deep insertion or even pressing through of the closure insert 16 is also prevented. The union element 14 is subsequently pushed over the fastening ring 15, whereby the projections 24 engage in the grooves 25 provided for that purpose and thus fix the union element 14 to the fastening ring 15 in a rotationally secure manner. By that means, a rotational movement of the union element 14 can be transferred to the external thread 10a.
(72) The position of the projections 24 and of the grooves 25 are arranged at 120 degrees in relation to the threading position, by which means it is ensured that, upon the insertion of the union elements 14, the connecting element 4 comes to lie in a precise position on the threaded collar 7 and can be fixed there if the closure element 3 is attached to the cartridge 1.
(73) FIGS. 33 to 38 show, in serial sequence, a perspective view, a first lateral view, a view from above, a view from below, a frontal view, and a second lateral view of the closure element 3 of FIG. 32 in assembled form.
(74) FIG. 39 corresponds to the view from above of FIG. 35, but shows, however, the sectional planes A-A and B-B, the sectional view of which are shown in FIGS. 40 and 41.
(75) The sectional view of FIG. 40 shows the operating principle of the axial securing of the closure insert 16 in the fastening ring 15. Both locking tabs 27, which are positioned diametrically opposite to one another, engage behind the annular projection 28 encircling the internal contour of the opening 26, and thus prevent a further axial movement of the closure insert 16 in the direction of the positioning tongue 5, so that the closure insert 16 is held in a loss-secure manner. At the same time, an unscrewing of the closure element 3 permits an extraction of the bearing pins 3c out of the corresponding outlets 9 of a cartridge (not depicted).
