Description

The invention relates to cartridges, in particular a film cartridge, as well as a method for manufacturing a film cartridge.

Known film cartridges with one or more chambers containing chemical masses, such as putties, sealants or adhesive masses. Such a film cartridge is inserted into the holder of the extrusion device intended for the cartridges, by means of which chemical masses are applied in a desired place.

The use of cartridges, in which the chamber is essentially formed by a film sleeve, is advantageous since empty cartridges can be disposed of without great expense and without wasting a lot of space. For example, the formation of a chamber is known from German Patent DE 295 01 255 U1 by means of collecting both ends of a film bag into a bundle, which in each case is closed with a metal clip. However, it is disadvantageous in this case that, firstly, the axial ends of the chambers are not hermetically sealed, so that a certain leak of especially volatile liquid components occurs all the time, partly under the influence of capillary forces in the bundle. Secondly, the problem arises of the reproducible opening of the film bag. For this purpose, in German Patent DE 295 01 255 U1, a piercing device with two piercing tabs is used, which must form a predetermined hole in the film bag. The actual shape of the hole, however, depends on how the film material is torn in a particular case.

The objective of the invention is to create a simple and cheaply made film cartridge, which can be opened reliably and reproducibly.

This is achieved using a film cartridge having a film sleeve covering at least one chamber forming, and a cover separate from the film sleeve that covers one axial end of the film sleeve, with at least one first opening being made in the cover for each camera through which the chamber can be filled with filler material, and a plug covering the first hole. The advantages of the film sleeve, namely the speed and cheapness of manufacturing, as well as saving space during storage after emptying, are preserved. Using a separate cover, however, allows you to provide holes of a given configuration, preserving the shape if necessary, which, after removing or destroying the plug, can be purposefully opened (released) by a given diameter. It is preferable to open when the film cartridge is inserted into the extrusion device. In addition, thanks to this design, you can first make a film cartridge, and then fill it, since the first hole is simply closed after a separate filling process. For previous film cartridges, manufacturing and filling was carried out in one working step, since the film bag was clogged at both ends and thus did not have openings through which filling could be done.

The second axial end of the film sleeve may be closed separately from the film sleeve and associated bottom. Thus, it is possible to simply form a cylindrical chamber with a given volume. The bottom may consist, for example, of a cover material or a film sleeve material, and at least approximately correspond to the size of the cover in size.

The cover is preferably made of a more rigid material than the film sleeve, for example, polyethylene, polypropylene, polybutylene terephthalate or acrylonitrile butadiene styrene.

The film cartridge can be implemented as a multi-chamber cartridge, and various chambers can be filled with various filler materials that mix with each other only when the material is dispensed.

If several chambers are provided, they can be filled with various filler materials. Filler materials can form, for example, components of sealants, cement mortars, coating materials, paints, semi-finished foams, adhesives or lubricants. However, it is also possible to fill at least two chambers with the same material in order to provide a higher mixing ratio. Several chambers can be formed, for example, by dividing the film sleeve in the axial direction into several chambers extending in the axial direction parallel to each other. To do this, one or more segments of the film, which in the axial direction extend parallel to the film sleeve, can be inserted into it (sleeve) and glued or welded to the walls of the film sleeve, as well as to each other. While the film cartridge is closed, the cameras are completely separated from each other.

Several chambers can also be formed by providing another film sleeve located in the first film sleeve so that the first film sleeve extends parallel to the second film sleeve. Such a system allows, in particular, to achieve a large difference in the volume of cameras. A thin second film sleeve placed inside the first film sleeve may comprise a component that is required in the finished mixture in a much smaller volume fraction than the component in a large, external chamber. The cameras can be located coaxially, but the inner film sleeve can also be offset away from the axis. The use of film sleeves and units can also be combined so that, depending on the purpose of the application, an arbitrary combination of cameras could be achieved.

All chambers preferably extend to the lid, where each chamber has its own corresponding first opening. It is also preferred that all chambers extend to the bottom.

Preferably, a head is provided that is rigidly connected to the lid and has an outlet at the receiving element for the mixer tube provided for dispensing the filler material. It is advisable that the head (end part) be made of a relatively rigid material, so that during the delivery of the filler material, the outlet opening is not deformed.

The outlet (before applying the film cartridge) can be covered with a lid.

At least one channel can be formed between the cap and the inner wall of the head to guide the filler material to the outlet. In the case of several chambers, it is preferable to form one channel per chamber, it is preferable that these channels pass separately up to the outlet to prevent mixing of the filler materials of the individual chambers inside the film cartridge. Thanks to the channels, the individual components and filler materials, even when the film cartridge is opened, are completely separated from each other before leaving the outlet.

The connection between the film sleeve and the lid or the bottom, as well as between the lid and the head can be glued or welded, in particular, ultrasonic, laser or thermal welding.

The head and cover can also be snapped-in or snapped in. Of course, you can also apply a combination of these activities. Preferably, all connections are made so that the chambers are closed tightly.

In a preferred embodiment of the invention, an evacuation hole separate from the first opening is provided for each chamber. When filling film cartouches, it provides various advantages. For example, you can fill the chambers through the first hole to such an extent that the channel is filled with filler material to the outlet. This minimizes the preliminary phase, since the mixing ratio of multicomponent cartouches directly from the very beginning corresponds to the desired ratio.

It is possible to close adjacent first openings, emptying openings or openings for filling with common plugs.

Preferably, one or more films, for example, a composite or single-layer film, are provided as plugs (plugs) for both the first openings, the drainage openings, and the discharge opening. Films can consist, for example, of one or more layers of polypropylene, polyethylene, polyethylene terephthalate, ethylene-vinyl copolymer and / or aluminum.

The film is preferably welded or glued to the edge of the hole. To facilitate removal, a pull tab may be provided on the film.

As a plug, it is also possible to provide a metal plate and a part made by injection molding, in particular for filling holes located in the head. These covers are also preferably connected (closed) to the edge of the hole by gluing or welding.

The plug may be fitted directly to this particular hole.

Several options are available for opening or removing a stub. For example, the film can be made so that it can be removed as a whole, and after removing the film, the hole for emptying or the outlet would be completely free. However, it is possible that there is one or more weakened zones on the film along which the film (due to the excess pressure exerted by the extrusion device) tears in a controlled manner and, in a predetermined manner, releases the outlet or drain hole. Attenuation zones can, for example, be created with high reproducibility by laser removal.

The plug, especially for the first holes, can be provided, for example, with data on the components of the filler material, on the batch number or also on the expiration date. If necessary, marking of the film cartridge can also be applied to it.

To improve the filling procedure, the edge of the first hole and / or outlet may be provided with a tapered narrowing. The narrowing is intended to center the filling tube and thus provide a more tight fit of the tube to the edge of the hole.

Preferably, at least one protrusion is formed at the edge of the first hole and / or outlet. The protrusion, preferably extending along the generatrix, or the corresponding ridge, is intended for scraping the filler material from the filling tube when the tube is removed, so that the material does not enter the filling device. It is also possible to axially align several protrusions or ridges one after the other in order to scrape off the maximum possible fraction of the aggregate material.

It is also possible to use coarse or relatively large solid filler materials in the individual components of the filler materials, since the first opening can be made so large without any difficulties that it can be introduced without difficulty. The size of the channels can also be simply selected so that coarser solid filler materials can be used in filler materials.

Since the chambers are hermetically sealed and separated from each other, and the leakage rate due to the design of the chambers is practically zero, a long shelf life can be achieved.

The external geometric characteristics of the film cartridge can be the same regardless of the number of components used. Thus, the applicability of a single extrusion device to various types of filler materials can be ensured.

The outlet may also remain open. In this case, it is preferable to close the emptying hole with a plug equipped with a weakening zone, and when an additional extrusion force is applied to the extrusion device when the new film cartridge is still closed, the internal pressure exceeds the force required to open the weakening zone. This option allows you to automatically and in a controlled manner open the newly installed film cartridge.

By attaching a certain configuration to the cross-section of the channels and / or the cross-section of the first holes or the drain holes, it is possible to throttle individual filling materials from different chambers, which makes it possible to very precisely control the amount of filler materials dispensed in each case. It also allows you to compensate for differences in fluidity at different rheological indicators of individual filler materials.

When implementing the method for manufacturing a film cartridge, for example, as described above, the following steps are carried out:

- the manufacture of at least one chamber by connecting the cover with a film sleeve,

- filling the chamber with filler material through the first hole in the lid and

- closing the first hole.

The film cartridge is completely made before filling. They also install, possibly, the bottom, so that the chambers are completely closed, with the exception of the first hole and, possibly, another drain hole. As a second step, filler material is introduced into the chamber, which may occur in a different machine than the manufacture of an empty film cartridge. After filling, the first hole is closed, and the film cartridge, thus, is hermetically sealed.

The head described above, with the exception of the mixer tube for dispensing filling material, can be rigidly connected to the cap before or after filling.

If the filling is carried out after the installation of the head, it is preferably filled with filler material and the channels between the head and the cover.

If the head is installed after filling, then filling is done through the first hole, which is closed after filling and before fixing the head.

If the filling is carried out after the installation of the head, the first hole and / or the drain hole may remain open, and only the holes (filling hole and dispensing hole) in the head are closed.

If there is an additional drain hole for each chamber in the lid, then another fill hole is provided in the head, preferably coaxial with the first hole.

It is advisable to carry out the filling using a filling tube, which is introduced into the chamber through the first hole, and the filling is carried out below the surface level. As the filling level increases during the filling process, the tube is pushed further and further back. This allows you to fill the chambers without air bubbles. The filling process can be supported by vacuum or back pressure. This is especially useful when it is necessary to fill the channels up to the outlet.

Air may leave the chambers, for example through emptying openings (if provided). When filling with the installed head, it is also possible to give the filling hole in the head a smaller cross section than the first hole, so that although the filling tube is sealed tightly to the filling hole, due to the larger size of the first hole, air can exit the chamber when filling.

Opening the film cartridge is simple, since the film that is used for capping can simply be removed without the use of tools, or this film is torn in a predetermined way when a certain force is applied to the film cartridge from the outside with the extrusion tool. Since a predetermined hole is always formed, the forces necessary for the application process are unchanged when opening and extruding the filler material.

FIGURE 20 is a schematic detailed view of Figure 19.

The figure 1 shows the film cartridge 100 in accordance with the first form of execution. The film cartridge 100 includes in this case two film containers 102, as well as a head 104 (see figure 3). The head 104 at the upper axial end is connected to both, adjacent to each other, film containers 102.

In figure 2, one of the film containers 102 is presented in more detail. The first, outer film sleeve 106 is divided by a separator 108 (see figures 6 and 7) into two axially separated from each other in parallel axes 110, 112. As can be seen in figures 6 and 7, both cameras 110, 112 can be made one or different sizes, which is achieved by the location of the separator 108. Instead of a single separator 108, you can also provide several separators 108, which can extend over the cross section of the film sleeve 106 in an arbitrary way.

In figures 6 and 7, the film sleeve 106 and the separator 108 are made of a single film fragment. However, it is also possible to use a film sleeve with a closed loop (closed generatrix), for example, made by extrusion, and the separator 108 to enter inside. The spacer 108 is mounted on the film sleeve 106 in this case by gluing or welding in any suitable manner.

The axial end of the film sleeve 106 facing away from the head 104 is closed by a bottom 114 not shown in more detail. The bottom 114 in this case is a piece of film that is connected to the axial end of the film sleeve 106 and a spacer 108 by gluing or welding, so that chambers 110, 112 at this end hermetically isolated from the environment.

At the upper axial end of the chamber 110, 112 are closed by a cover 116, which, like the bottom 114, is firmly connected to the film sleeve 106 and the separator 108, welding or gluing. A film sleeve 106, a separator 108, a bottom 114 and a cover 116 delimit the chambers 110, 112 and completely cover them.

However, several openings are made in the lid 116, in this case, for each of the chambers 110, 112, one first hole 118 and one separate drain hole 120. The lid 116 consists in this case of a relatively hard film material. It can be stronger than the material used for the film sleeve 106. In this case, the head 104 is made of a harder material than the cap 116, and provides stability to the shape of the entire upper axial end of the film cartridge 100. In particular, the head 104 ensures a constant diameter holes, including when using a film cartridge 100 in an extrusion device (not shown).

Holes are also made in the head 104, namely, the central outlet 122, and for each of the chambers 110, 112, one filling hole 124 separate from the outlet 122, which, respectively, are aligned with the first holes 118 in the cover 116. In FIG. 3 the situation is presented, respectively, for only one camera 112, respectively, for one film container 102. The head 104, however, has only one common outlet 122 for all cameras 110, 112 and all film containers 102.

Between the inner wall of the head 104 and the upper side of the lid 116 are made channels 126, which, respectively, lead from one of the drainage holes 120 to the outlet 122.

An outlet 122 is located at the end of the nozzle-shaped receiving element 128, which forms the space for the mixer tube, designed to dispense the filler material placed in the chambers 110, 112.

The partition walls 130 that define the channels 126 in the interior between the walls of the head 104 and the cap 116 extend directly to the outlet 122, so that this hole is actually divided into as many channels 126 as there are chambers.

Prior to the use of the film cartridge 100, the outlet 122 is hermetically sealed with a plug 132. In the case shown here, the plug 132 is a film in which for each chamber 110, 112 there is an attenuation zone 134, in each case located in the middle above one of the channels 126 in the outlet region holes 122 (see figure 5).

All chambers 110, 112, prior to use of the film cartridge 100, are hermetically isolated from the surroundings. Mixing of various filler materials in separate chambers 110, 112 does not occur in this state.

The filling openings 124 are also hermetically sealed with a plug 136. The plug 136 is also a film on which the product name, the names of the filler materials contained in the individual chambers 110, 112, the batch number, and the expiration date of the film cartridge are printed, and this film thus serves to mark the film cartridge 100.

As a plug 136, you can also use a metal plate or part made by injection molding. In all cases, the plug 136 completely seals the openings for filling 124, so that the filler material cannot protrude from the chambers 110,112.

In the head 104, in this case, the filling channel 138 extends from the edge of the filling hole 124 directly to the first hole 118 in the cover 116. The filling channel in the area where it forms the edge of the filling hole 124 has a tapered narrowing 140 ending in a protrusion 142 that extends along the generatrix. The protrusion 142 defines a section with a minimum cross-section of the filling channel 138.

In the manufacture of the film cartridge 100, a film container 102 is first manufactured. For this, a film sleeve 106 is made from a flat film segment or as a film sleeve with a closed loop. Possible separators 108 are fixed in the film sleeve 106. A bottom 114 is mounted on the lower axial end and glued or secured by ultrasonic, laser or thermal welding. A cover 116 is also fixed on the opposite axial end. The spacers 108 are also fixed on the bottom 114 and the cover 116, so that closed chambers 110, 112 are formed. The first openings 118 and the drainage openings 120 are still open.

In the next step, the head 104 is rigidly connected to the cap 116, for example, by gluing or welding.

Channels 126 are now also formed between the cap 116 and the head 104. The outlet 122 is also still open, as well as the filling holes 124. The film cartridge 100 is now ready for filling as a prefabricated product. Filling can be done in a different machine than manufacturing.

Through the filling holes 124 and the first holes 118, a filling tube (not shown) is now introduced into the respective chambers 110, 112 and a specific filler material is provided for the chambers 110, 112. Moreover, starting from the bottom of the chambers 110, 112, as the tube fills, the tube is pushed further and further back, so that filling is carried out with the tube below the level and without bubbles. The tapered constriction 140 provides centering of the fill tube in the fill hole 124, and also substantially seals the fill hole 124 with the fill tube. The air leaving the chambers 110, 112 exits through the drainage hole 120 and the outlet 122. During the filling process, the filling tube is drawn further and further back, and the protrusion 142 scrapes excess filler material from the filling tube so that it does not enter the device for filling in. In the filling channel 138, it is possible to provide several protrusions 142 arranged axially one after another, and only one is represented in this case.

Filling is carried out until the filler material protrudes from the drainage holes 120, and also fills the channels 126 to the outlet 122.

Filling can be maintained by creating a vacuum at outlet 122 or by creating back pressure.

After filling is completed, the outlet 122 is hermetically sealed with a plug 132. The individual channels 126 are also completely separated from each other.

The filling openings 124 are also hermetically sealed with caps 136. The first openings 118 and the drainage openings 120 in this example remain open.

In this form, the finished film cartridge 100 can be inserted into an extrusion device, wherein the initially created pressure provides a break in the weakening zone 134 in the plug 132 of the outlet 122. Already from this moment, the filler material leaves all chambers 110, 112 in the desired mixing ratio.

The plug 132 can also be made so that the user removes it before installing it in the extrusion device.

The shape of the channels 126 and the size of the drainage holes 120 are selected depending on the material used in the chambers 110, 112 so that either the holes and channels 126 are large enough for unhindered flow of materials with large fillers, or that throttling is ensured for those required only in a small amount and / or fluid filling materials. In this sense, each of the channels 126 may be different from the others. Changes can be achieved by varying the shape of the head 104 and the design of the separation walls 130.

In the presented embodiment, a cartouche for four components was created, in which each of the chambers 110, 112 of both film containers 102 contains a different filler material. The filler materials come into contact with each other only after leaving the outlet 122 and are mixed in the mixing tube mounted on it.

In figures 8-12 presents a second form of execution of the film cartridge 200.

For components that coincide with the first form of execution, the symbols that have already been entered are retained.

In this case, the divided chambers 110, 112 and 113 are created by pulling the second film sleeve 206 into the first film sleeve 106. Additionally, a separator 108 is provided here, as in the first embodiment, which is located between the wall of the first film sleeve 106 and the wall of the second film sleeve 206 so that a total of three cameras are formed. You can also provide several second film sleeves 206 or additionally subdivide them with dividers.

As in the first embodiment, each of the chambers 110, 112, 113 in the cover 216 corresponds to a first opening 118.

This arrangement is valid for both film containers 202 (see figure 8).

Unlike the first embodiment, there are no separate emptying openings. Accordingly, the channels 226 in the head 204 are designed so that they lead from the first hole 118 to the outlet 122. Otherwise, the head 204 is made similar to the head 104 of the first embodiment. The filling holes 124 in the head 204 are equipped with a conical narrowing 140 and a protrusion 142 extending along the generatrix. In this case, however, the diameter of the first hole 118 is larger than the diameter of the filling channel 138 in the region of the protrusion 142, so that during filling the air can leave the filling just now the camera.

Since three chambers 110, 112, 113 are provided for each film container 202 in this case, six weakening zones are distributed along the plug 132 of the outlet opening 122, and the outlet opening 122 is divided into six channels 226.

As in the first embodiment, for the manufacture of the film cartridge 200, film containers 202 are first manufactured and connected to the head 204. The individual chambers 110, 112, 113 are filled through filling holes 124 in the head 204 and first holes 118 in the cover 216. Here, the filling can also be carried out until the material also fills the channels 126 up to the outlet 122. After filling, a plug 132 is installed on the outlet 122 and plugs 136 on the filling hole 124.

In separate chambers 110, 112, 113, in each case, a different filler material can be placed, so that a mixture of six components is formed. You can, however, also fill several chambers with the same material in order to obtain a higher mixing ratio. You can get the mixing ratio from 1: 1 to 1:50 without the need to change the external geometric parameters of the film containers 202.

In figures 13-16 presents a third form of execution of the film cartridge 300.

In contrast to the embodiments described so far, in this case, the film container 302 is first filled and then the head 304 is fixed to the lid 316.

The formation and division of both film containers 302 mainly corresponds to the first form of execution.

In the head 304, there are no holes other than the outlet 122. In the manufacture of the film cartridge 300, a film container 302 is first made. It is filled through the first holes 118, the edge of the holes 118, like the edge of the hole 124 described above, can be provided with a tapered narrowing and a sealing lip (see figure 20). After the chambers 110, 112 are completely filled, the first openings 118 are closed with plugs 340. The plugs 340 in this case are made in the form of a film with a weakening zone 342, as shown schematically in FIG. 15. Then, the head 304 is rigidly connected to film containers 302, for example by gluing or welding. The plug 132 of the outlet 122 can be implemented before or after installing the head 304 on the film container 302.

In figures 17-20 shows a fourth form of execution of the film cartridge 400.

Here, as in the second embodiment, the chambers 110, 112, 113 are formed by placing the second film sleeve 206 inside the first film sleeve 106. On the contrary, the design of the head 404 and the first holes 118 are the same as in the third embodiment that has just been described.

In this case, also after manufacturing the film containers 402, the individual chambers 110, 112, 113 are first filled and the first holes 118 are closed with caps 440. Then, the head 404 is rigidly connected to the cover 416.

In the last two forms of execution, the channels 326, 426 are not filled with filler material prior to the use of film cartridges 300, 400.

Therefore, in these embodiments, it is also possible to leave the outlet 122 open.

In this embodiment, it is also shown that the first hole 118, which is used to fill the chambers 110, 112, 113, has a tapered narrowing 140 in the region of its edge and a protrusion 142 extending along the contour for scraping the filler material from the filling tube.

In all forms of execution, the channels 126 - 426 in the intermediate part of the head and the cover are made so that the filler material emerging from the individual chambers is mixed only when leaving the outlet 122.

The holes 118, 120, 122 and 124 in each case may be round or elliptical.

Weakening zones can be realized in the form of lines, circles, crosses or ellipses, broken lines or solid lines.

All signs of individual forms of execution can be arbitrarily combined with each other or replaced with each other, which remains at the discretion of a specialist.
