Description

  The present invention relates to thin film cartridges and methods for making thin film cartridges.

  For example, thin film cartridges having one or more chambers containing pasty chemicals such as fillers, sealants or adhesives are known. Such a thin film cartridge is inserted into a cartridge holder of a dispenser, and the chemical substance is applied to a desired location by the dispenser.

  It is convenient to use a thin film cartridge in which the chamber is substantially formed by a thin film tube, because it can be discarded without taking up much space and without much effort. For example, it is known from German utility model No. 2951255 to form a chamber by combining two ends of a thin film bag into one braid and closing each with a metal clip. However, this has the disadvantage that on the one hand the axial end of the chamber is not hermetically closed, so that in particular the movable fluid part is always leaked to some extent due to the capillary effect of the braid. Became clear. On the other hand, reproducibility when opening the thin film bag is a problem. For this purpose, German Patent Utility Model No. 2951255 uses a puncture device having two puncture spades to open a thin film bag in a predetermined shape. However, the actual shape of the opening depends on how the thin film material breaks in each case.

German utility model 2951255

  An object of the present invention is to form a thin film cartridge which can be opened reliably and reproducibly and which can be manufactured easily and inexpensively.

  The object is to provide a membrane tube that circumferentially surrounds at least one chamber and a cover that is separate from the membrane tube and that closes the axial end of the membrane tube, filling the chamber for each chamber. This is solved by a thin film cartridge having a cover formed with at least one first opening capable of being filled with a material and a lid for closing the first opening. The use of a thin-film tube retains its advantages, that is, quick and inexpensive production and storage that does not take up space after ejection. Moreover, the use of a cover separate from the thin-film tube makes it possible to provide predetermined shape-stable openings as required, and these openings are intentionally made with a predetermined diameter by removing or breaking the lid. Can be opened. This opening is preferably performed when the thin film cartridge is inserted into the dispenser. In particular, with such a configuration, a thin film cartridge can first be made and then filled. This is because the first opening can also be easily closed after a filling process separate from the creation. In conventional thin film cartridges, fabrication and filling have been performed in one work process. This is because the membrane bag was tightly closed at both ends and therefore did not have an opening that could be filled.

  The second axial end of the membrane tube may be closed by a bottom coupled to the membrane tube, separate from the membrane tube. In this way, a cylindrical chamber having a predetermined volume can be easily formed. The bottom is made of, for example, a cover or thin-film tube material and may at least approximately correspond to the cover in terms of dimensions.

  The cover is preferably made of a material that is more rigid than the thin-film tube, such as polyethylene, polypropylene, polybutylene terephthalate or acrylonitrile-butadiene-styrene.

  The thin film cartridge may be formed as a multi-chamber cartridge. In this case, different chambers can contain different fillers, and these fillers may be mixed with each other only when the material is discharged.

  When a plurality of chambers are provided, these chambers may be filled with different fillers. The filler may consist of a composite component of, for example, a sealant, mortar, coating, pigment, foamable semi-finished product, adhesive or colorant. However, it is also possible to fill at least two chambers with the same filler to achieve a high mixing ratio. The plurality of chambers may be formed, for example, by dividing the thin film tube into a plurality of chambers extending in parallel with each other in the axial direction by a partition. For this purpose, one or more thin film portions extending in parallel in the axial direction with respect to the thin film tube may be inserted into the thin film tube and bonded or welded to the wall of the thin film tube and to each other. The individual chambers are completely separated from one another when the thin film cartridge is closed.

  The plurality of chambers may be formed by disposing the second thin film tube in the first thin film tube such that the first thin film tube extends in parallel with the second thin film tube. With such a configuration, a large volume difference can be provided between the chambers. The thinner second membrane tube, located inside the first membrane tube, can also contain components that occupy a very small percentage of the volume in the finished mixture. The chambers may be arranged coaxially, but the inner membrane tube may be offset from the axis. A thin film tube and a partition can also be combined, thereby achieving an appropriate configuration of the chamber depending on the application.

  All the chambers preferably extend to a cover provided with a first opening corresponding one-to-one with each chamber. All chambers preferably extend to the bottom.

  Preferably, a head portion is provided that is firmly coupled to the cover and includes a discharge opening provided in a storage portion that stores a mixing tube for discharging the filler. The head part is advantageously made of a relatively rigid material so that the discharge opening is not deformed when the material is discharged.

  The discharge opening may be closed by a lid before using the thin film cartridge.

  Between the cover and the inner wall of the head portion, at least one passage for guiding the filler to the discharge opening may be formed. In the case of multiple chambers, preferably one passage is formed per chamber, which advantageously extends separately to the discharge opening, whereby the filling material of the individual chambers is mixed in the thin film cartridge. It is prevented. Through the passage, the individual components and fillers are completely separated from each other before discharge from the discharge opening even when the thin film cartridge is broken.

  The connection between the thin film tube and the cover or the bottom and between the cover and the head may be made by gluing or welding, in particular ultrasonic, laser or hot welding.

  The head part and the cover may be coupled by locking or caulking. Of course, a combination of these means may be used. All connections are advantageously configured such that the chamber is hermetically closed.

  In a preferred embodiment of the present invention, one discharge opening separate from the first opening is provided for each chamber. Thereby, various advantages are obtained when the thin film cartridge is filled. For example, it is possible to inject filler through the first opening and fill the chamber until the passage is completely filled with filler to the discharge opening. Thereby, since the mixing ratio in the multi-component cartridge corresponds to the desired mixing ratio from the beginning, it is possible to minimize the trouble of setting the mixing ratio.

  Adjacent first openings, discharge openings or filling openings can be closed by a common lid.

  As a lid for the first opening, the discharge opening and the discharge opening, one or more thin films, for example a composite thin film or a single thin film, are preferably provided. The thin film may be made of, for example, one or more layers of polypropylene, polyethylene, polyethylene terephthalate, ethylene vinyl copolymer and / or aluminum.

  The lid membrane is advantageously welded or glued to the edge of the opening. In order to easily remove the lid, the membrane may be provided with a tab that can be peeled off.

  In particular, a small metal plate or an injection molded member may be provided as a lid for the filling opening of the head portion. These lids are also preferably glued or welded to the edge of the opening.

  The lid may be attached directly to each opening.

  There are several possibilities for opening or removing the lid. For example, the thin film may be pulled away from the entire thin film, and the discharge opening or discharge opening may be completely released after the thin film is removed. However, the membrane may comprise one or more fragile zones, along which the membrane is ruptured in a controlled manner by the pressure applied to the dispenser and in a predetermined manner the discharge opening or discharge. Release the opening. The fragile zone can be created reproducibly by laser ablation, for example.

  The lid, in particular the lid for the first opening, may be provided with a material designation such as, for example, a filler component, batch number or expiration date. In some cases, it can also be used for labeling thin film cartridges.

  In order to improve the filling process, a conical taper may be provided at the edge of the first opening and / or the discharge opening. The taper serves to center the injection lance and thereby more tightly close between the injection lance and the edge of the opening.

  Advantageously, at least one lip is formed at the edge of the first opening and / or the discharge opening. A circumferentially annular lip or a corresponding ridge preferably serves to wipe off the filling material from the filling lance when the filling lance is pulled back and to prevent the filling material from entering the filling device. A plurality of lips or ridges can also be arranged continuously in the axial direction, so that as much of the filler as possible is wiped off.

  Coarse or relatively large filler particles can also be used for the individual components of the filler. This is because the first opening can be formed in such a size that can fill such a component without any problem. It is also possible to simply select the size of the passage so that coarser filler particles can be inserted into the filler.

  The chambers are hermetically closed and separated from one another, and the leak rate can be substantially zero with such a chamber configuration, so that a long storage period can be achieved.

  The outer shape of the thin film cartridge can also be formed equally regardless of the number of components used. In this way, one dispenser can be used for different types of fillers.

  The discharge opening may not be closed. In this case, the discharge opening is advantageously closed by a lid with a fragile zone, and when a new thin film cartridge that is still closed is inserted into the dispenser and pressure is applied, the internal pressure opens the fragile zone. It can be made to exceed the force necessary to do. In this way, the newly inserted thin film cartridge is automatically controlled and released.

  The shape of the cross-section of the passage and / or the cross-section of the first opening or the discharge opening can cause the squeezing action of the individual fillers from different chambers, thereby greatly reducing the amount of filler discharged respectively. Can be adjusted accurately. In this way, flow differences can be provided when the rheology of the individual fillers is different.

For example, in a method for making a thin film cartridge as described above, the following steps are performed:
Creating at least one chamber by bonding the cover and the membrane tube;
Filling the chamber with a filler through the first opening of the cover and closing the first opening is performed.

  The thin film cartridge is filled after completion. The optional bottom is also inserted and the chamber is completely closed except for the first opening and possibly other discharge openings. As a second step, the filler is then filled into the chamber and the filling is performed on a machine other than making an empty thin film cartridge. After filling, the first opening is closed, whereby the thin film cartridge is hermetically closed.

  The head part having a receiving part for the mixing tube for discharging the filler can be firmly connected to the cover before or after filling.

  If the filling is carried out after the head part has been installed, the passage between the cover and the head part is advantageously filled with a filler.

  If the head part is attached after filling, the filling takes place via the first opening, which is closed after filling and before fixing the head part.

  When filling is performed after the head portion is attached, the first opening and / or the discharge opening may remain open, and only the opening (filling opening and discharge opening) of the head portion is closed.

  If the cover is provided with an additional discharge opening corresponding to each chamber, another filling opening is advantageously provided which is aligned with the first opening of the head part.

  The filling is advantageously performed via an injection lance that is inserted into the chamber through the first opening to effect subsurface filling. As the filling level increases, the injection lance is gradually pulled back during filling. This makes it possible to fill the chamber without bubbles. The filling process can also be assisted by vacuum or counter pressure. This is particularly effective when the passage to the discharge opening should be filled.

  The air in the chamber can escape through these discharge openings, for example, if discharge openings are provided. When the head part is attached during filling, the filling opening of the head part can also be formed with a smaller cross-section than the first opening, so that the injection lance is in intimate contact with the filling opening. Even air can escape from the chamber during filling through the gap in the first opening.

  The thin film cartridge can be easily opened. This is because a thin film used as a lid can be easily torn without a tool, or when a predetermined force is applied to the thin film cartridge, the thin film is ruptured from the outside in a predetermined manner. Since the predetermined opening always occurs, the forces essential for the application process are kept uniformly during opening and discharging of the filler.

FIG. 20 is a schematic detailed view of FIG. 19.

  FIG. 1 shows a thin film cartridge 100 according to the first embodiment. In this case, the thin film cartridge 100 includes two thin film containers 102 and a head unit 104 (FIG. 3). The head unit 104 is coupled to each of two thin film containers 102 arranged adjacent to each other at the upper end in the axial direction.

  FIG. 2 shows the thin film container 102 in more detail. The first outer thin-film tube 106 is divided into two parallel chambers 110 and 112 separated from each other along the axial direction A by a partition 108 (see FIGS. 6 and 7). As shown in FIGS. 6 and 7, the two chambers 110, 112 may be formed of the same size or different sizes, which is achieved by the arrangement of the partitions 108. Instead of the single partition 108, a plurality of partitions 108 may be provided and appropriately extended on the cross section of the thin film tube 106.

  6 and 7, the thin film tube 106 and the partition 108 are made of a single thin film member. However, it is also possible to insert the partition 108 into the interior using, for example, a closed thin film tube made by extrusion. The partition 108 is fixed to the thin-film tube 106 here by adhesion or welding, but an appropriate method is appropriately selected.

  The axial end of the thin-film tube 106 opposite to the head portion 104 is closed by a bottom portion 114 that will not be further described here. The bottom 114 is here a thin film member that is bonded or welded to the axial ends of the thin film tube 106 and the partition 108 so that the chambers 110, 112 are hermetically sealed to the surroundings at this end. Is closed.

  At the upper axial end, the chambers 110, 112 are closed by a cover 116, which, like the bottom 114, is rigidly connected to the membrane tube 106 and the partition 108 by gluing or welding. The membrane tube 106, the partition 108, the bottom 114 and the cover 116 define the chambers 110, 112 and completely enclose these chambers.

  However, a plurality of openings are formed in the cover 116, and in this case, a first opening 118 and a separate discharge opening 120 are formed for the chambers 110 and 112, respectively. The cover 116 is here made of a relatively rigid thin film material. This thin film material may be more rigid than the material used for the thin film tube 106. The head portion 104 is made of a material stronger than the cover 116 here, and provides shape stability to the entire upper end in the axial direction of the thin film cartridge 100. In particular, the head portion 104 serves to keep the diameter of the opening constant even when the thin film cartridge 100 is used in a dispenser (not shown).

  Similarly, an opening, that is, one central discharge opening 122, and a filling opening 124 that is separate from the discharge opening 122 are formed in each of the chambers 110 and 112. And the first opening 118 of the cover 116 are aligned with each other. FIG. 3 shows a state where only one chamber 112 of each thin film container 102 is visible. However, the head 104 includes a single common discharge opening 122 for the entire chamber 110, 112 and for all thin film containers 102.

  Between the inner wall of the head part 104 and the upper surface of the cover 116, passages 126 are formed, each leading from the discharge opening 120 to the discharge opening 122.

  The discharge opening 122 is disposed at the end of a tubular storage portion 128 that stores a mixing tube for discharging the filler stored in the chambers 110 and 112.

  A partition wall 130 defining a passage 126 provided in an inner chamber between the wall portion of the head portion 104 and the cover 116 extends straight to the discharge opening 122, whereby the passage 126 is provided with a chamber. Is effectively divided into as many as

  Prior to using the thin film cartridge 100, the discharge opening 122 is tightly closed by a lid 132. In the illustrated embodiment, the lid 132 is a thin film, and the thin film comprises a weak zone 134 corresponding to each chamber 110, 112, which is a zone of the single passage 126 in the region of the discharge opening 122. It is arranged at the center (see FIG. 5).

  The chambers 110 and 112 are all sealed with respect to the surroundings before the thin film cartridge 100 is used. The mixing of the different filling materials in the individual chambers 110, 112 is not performed in this state.

  The filling opening 124 is similarly sealed by a lid 136. The lid 136 is here also a thin film, which is printed with the product name, the filling material contained in the individual chambers 110, 112, the batch number and the expiration date of the thin film cartridge. It plays the role of labeling the cartridge 100.

  It is also possible to use a metal small plate or an injection molded member as the lid 136. In either case, the lid 136 completely seals the filling opening 124 so that no filling material can flow out of the chambers 110, 112.

  In the head portion 104, a filling passage 138 extends straight from the edge of the filling opening 124 to the first opening 118 of the cover 116. The filling passage has a conical taper 140 in the region forming the edge of the filling opening 124, which tapers 140 terminate in a circumferential lip 142. Lip 142 defines the area of the smallest diameter cross section of fill passage 138.

  When the thin film cartridge 100 is manufactured, the thin film container 102 is first manufactured. For this purpose, the thin-film tube 106 is manufactured as a flat thin-film portion or a thin-film tube whose periphery is closed. An appropriately provided partition 108 is fixed inside the thin film tube 106. At the lower end in the axial direction, a bottom 114 is inserted and bonded, or fixed by ultrasonic, laser or hot welding. A cover 116 is similarly fixed to the end portion on the opposite side in the axial direction. In this case, the partition 108 is also fixed by the bottom 114 and the cover 116, thereby forming closed chambers 110 and 112. The first opening 118 and the discharge opening 120 are still open.

  Next, the head portion 104 is firmly coupled to the cover 116 by, for example, bonding or welding.

  Next, a passage 126 is also formed between the cover 116 and the head portion 104. The discharge opening 122 is still open like the filling opening 124. At this point, the thin film cartridge 100 is ready for filling as a prefabricated product. The filling may be performed by a machine different from the manufacturing.

  An injection lance now (not shown) is inserted into the respective chambers 110 and 112 through the filling opening 124 and the first opening 118, and a predetermined filling material is injected into each chamber 110 and 112. The injection lance in this case starts gradually from the bottom of the chambers 110, 112 and gradually withdraws as the filling progresses, thereby achieving a subsurface filling without bubbles (Unterspiegelbefuellung). The conical taper 140 provides centering of the injection lance at the fill opening 124 and serves to cause the fill opening 124 to be substantially sealed by the injection lance. Air to be exhausted from the chambers 110, 112 escapes through the exhaust opening 120 and the discharge opening 122. The filling lance is gradually pulled back in the filling process and the lip 142 wipes away any excess filling material from the filling lance so that it does not reach the filling device. Although a plurality of lips 142 arranged continuously in the axial direction may be provided in the filling passage 138, only one lip is shown here.

  The filling is performed until the filler flows out from the discharge opening 120 and the passage 126 is also filled up to the discharge opening 122.

  Filling can be facilitated by placing the discharge opening 122 in a vacuum state or applying pressure by adding a back pressure.

  After filling, the discharge opening 122 is sealed with a lid 132, whereby the individual passages 126 are also completely separated from one another.

  The filling opening 124 is also sealed by the lid 136. The first opening 118 and the discharge opening 120 are not closed in this embodiment.

  The produced thin film cartridge 100 can be inserted into the dispenser in this form, and the initially applied pressure serves to tear the fragile zone 134 provided in the lid 13 of the discharge opening 122. From this point of time, the filler is already discharged from all the chambers 110 and 112 at a desired mixing ratio.

  The lid 132 may be configured to be pulled away by the user prior to insertion into the dispenser.

  The shape of the passage 126 and the size of the discharge opening 120 is related to the filler used in the chambers 110, 112 so that the opening and passage 126 will flow out without obstructing the filler with larger filler particles. Or a volume of filler is low and / or a free-flowing filler is selected to be sufficient for the squeezing action to be performed. Each passage 126 may be configured differently in this sense. Variations can be obtained depending on the form of the head portion 104 and the partition wall 130.

  In the illustrated embodiment, a four component cartridge is implemented, and each of the chambers 110, 112 of the two thin film containers 102 contains a different filler. The fillers are first brought into contact with each other at the time of discharge from the discharge opening 122 and mixed in a mixing tube attached to the discharge opening 122.

  A second embodiment of the thin film cartridge 200 is shown in FIGS.

  The same elements as those in the first embodiment are retained.

  In this case, chambers 110, 112, and 113 separated by inserting the second thin film tube 206 into the first thin film tube 106 are realized. In addition, as in the first embodiment, another partition 108 located between the wall portion of the first thin film tube 106 and the wall portion of the second thin film tube 206 is provided. Thus, a total of three chambers are formed. It is also possible to provide a plurality of second thin film tubes 206 or to further partition these second thin film tubes by partitions.

  As in the first embodiment, the first opening 118 is provided in the cover 216 in each of the chambers 110, 112, and 113.

  This arrangement applies to the two thin film containers 202 (see FIG. 8).

  Contrary to the first embodiment, no independent discharge opening is provided here. Instead, a passage 226 is formed in the head portion 204 so as to communicate from the first opening 118 to the discharge opening 122. In other respects, the head unit 204 is configured similarly to the head unit 104 of the first embodiment. A conical tapered portion 140 and an annular lip 142 are provided in the filling opening 124 of the head portion 204. In this case, however, the diameter of the first opening 118 is larger than the diameter of the filling passage 138 in the region of the lip 142, so that when filling, air can escape from the chamber being filled.

  Since three chambers 110, 112, and 113 are provided for the thin film container 202, six weak zones are distributed to the lid 132 of the discharge opening 122, and the discharge opening 122 is divided into six passages 226. It is partitioned.

  In order to manufacture the thin film cartridge 200, the thin film container 202 is first manufactured and coupled to the head unit 204 as in the first embodiment. The individual chambers 110, 112, and 113 are filled through the filling opening 124 of the head unit 204 and the first opening 118 of the cover 216. Again, filling is performed until the filler fills the passage 126 to the discharge opening 122. After filling, the lid 132 is attached to the discharge opening 122 and the lid 136 is attached to the filling opening 124.

  Each chamber 110, 112, 113 may contain different fillers so that a six-component mixture is produced. However, it is also possible to fill several chambers with the same filler in order to obtain a higher mixing ratio. It is possible to implement a mixing ratio from 1: 1 to 1:50 without having to change the outer shape of the thin film container 202.

  A third embodiment of the thin film cartridge 300 is shown in FIGS.

  Unlike the embodiments described so far, the thin film container 302 is first filled before the head portion 304 is fixed to the cover 316. The configuration and compartments of the two thin film containers 302 substantially correspond to the first embodiment.

  The head unit 304 has no opening other than the discharge opening 122. When manufacturing the thin film cartridge 300, the thin film container 302 is first completed. The thin film container 302 is filled through the first opening 118, and a conical taper portion and a sealing lip may be formed at the edge of the opening 118 in the same manner as the edge of the opening 124 described above (see FIG. 20). ). After the chambers 110 and 112 are completely filled, the first opening 118 is closed by the lid 340. The lid 340 is here formed in the form of a thin film having a fragile zone 342 as schematically shown in FIG. The head portion 304 is then firmly coupled to the thin film container 302, for example by gluing or welding. The lid 132 of the discharge opening 122 can be closed before and after the head unit 304 is attached to the thin film container 302.

  17 to 22 show a fourth embodiment of the thin film cartridge 400.

  Here, as in the second embodiment, the chambers 110, 112, and 113 are formed by disposing the second thin film tube 206 inside the first thin film tube 106. On the other hand, the configuration of the head portion 404 and the first opening 118 is the same as that of the third embodiment described above.

  Also in this case, the individual chambers 110, 112, and 113 are first filled after the thin film container 402 is manufactured, and the first opening 118 is closed by the lid 440. The head portion 404 is then firmly coupled to the cover 416.

  In the last two embodiments, the passages 326, 426 are not filled with filler prior to using the thin film cartridges 300,400.

  Therefore, in these embodiments, it is possible to keep the discharge opening 122 closed.

  In these embodiments, the first opening 118 used to fill the chambers 110, 112, 113 has a conical taper 140 at the edge as well as an annular lip 142 for wiping the filler from the injection lance. I have.

  In all embodiments, passages 126-426 are formed in the intermediate head and cover so that filler material discharged from the individual chambers is only mixed when leaving discharge opening 122.

  The openings 118, 120, 122, and 124 may each be configured in a circular or elliptical shape.

  The fragile zone may be configured in a linear, circular, cruciform or oval shape with a dashed or solid line.

  All the features of the individual embodiments can be combined with each other or exchanged as appropriate at the discretion of the expert.
