Abstract
A foil cartridge is disclosed. The foil cartridge has a foil tube enclosing at least one chamber in the circumferential direction and a cover separate from the foil tube. The cover closes an axial end of the foil tube. At least one first opening is configured in the cover for each chamber, through which opening the chamber may be filled with a filling material. A closure is provided, which seals the first opening. To produce the foil cartridge, the chamber is established by connecting the cover with the foil tube. Then the chamber is filled with a filling material through the first opening in the cover and the first opening is sealed.
Description
- This application claims the priority of German Patent Document No. 10 2011 007 475.9, filed Apr. 15, 2011, the disclosure of which is expressly incorporated by reference herein.
- The invention relates to a foil cartridge as well as a method for producing a foil cartridge.
- Foil cartridges having one or more chambers containing chemical compounds such as putty compounds, sealants or adhesive compounds are known. This type of foil cartridge is used in a cartridge holder of a dispensing device which is used to apply the chemical compounds to the desired location.
- The use of foil cartridges in which the chamber is essentially formed by a foil tube is beneficial because empty cartridges may be disposed of without great expense and without requiring a lot of space. For example, it is known from German Patent Document No. DE 295 01 255 U1 that the chamber may be created by combining the two ends of the foil bag into a “ponytail,” which is then sealed by a metal clip. However, the disadvantage of this is, for one, that the axial ends of the chamber are not hermetically sealed so that there is always a certain amount of leakage especially of the mobile liquid content to some extent from the capillary forces in the “ponytail.” Secondly, there is the problem of reproducibly opening the foil pouch. To this end, a piercing device is used in DE 295 01 255 U1, which has two piercing spars that are supposed to create a defined opening in the foil pouch. Nevertheless, the actual shape of the opening depends upon how the foil material tears in individual cases.
- The object of the invention is creating a foil cartridge that is simple and cost-effective to produce, which can be opened reliably and reproducibly.
- This is achieved with a foil cartridge having a foil tube enclosing at least one chamber in the circumferential direction and a cover that is separate from the foil tube, the cover closing an axial end of the foil tube, wherein at least one first opening is configured in the cover for each chamber, through which opening the chamber may be filled with a filling material, and a closure, which seals the first opening. The advantages of the foil tube are retained, specifically quick and cost-effective production as well as space-saving storage after it is empty. However, the use of the separate cover permits defined and, if applicable, dimensionally stable openings to be provided, which may be uncovered by removing or destroying the closure in a targeted manner in a defined diameter. Opening is preferably accomplished when the foil cartridge is inserted into the dispensing device. In addition, because of this design, it is possible to first manufacture the foil cartridge and then fill it, because the first opening is also simple to seal even after a separate filling process. In the case of previous foil cartridges, manufacturing and filling were carried out in one production step, because the foil pouch was firmly sealed on both ends and thus did not have an opening through which a filling process could take place.
- The second axial end of the foil tube may be sealed by a base that is separate from the foil tube but connected thereto. In this way, it is possible to configure a cylindrical chamber with a defined volume in a simple manner. The base may be made, for example, of the same material as the cover or that of the foil tube and may correspond in terms of size and dimensions to at least approximately that of the cover.
- The cover is preferably formed of a more rigid material than the foil tube, e.g., polyethylene, polypropylene, polybutylene terephthalate or acrylnitrile butadiene styrene.
- The foil cartridge may be configured as a multi-chamber cartridge, wherein the different chambers are able to accommodate different filling materials, which are not mixed with one another until the material is dispensed.
- If several chambers are provided, they may be filled with different filling materials. The filling materials may form, for example, components of sealants, mortars, coating compounds, paints, foam intermediate products, adhesives or lubricants. But it is also possible for at least two chambers to be filled with the same filling material in order realize high mixing ratios. Several chambers may be formed, for example, in that the foil tube is subdivided in the axial direction into several chambers, which extend parallel to one another in the axial direction. For this purpose, one or more foil sections extending in the axial direction parallel to the foil tube are introduced into the foil tube and are glued or welded to the walls of the foil tube as well as among each other. The individual chambers are completely separate from one another as long as the foil cartridge is sealed.
- Several chambers may also be formed in that an additional foil tube is provided, which is arranged in the first foil tube so that the first foil tube extends parallel to the second foil tube. This design makes it possible to achieve in particular a larger volume difference between the chambers. A second foil tube lying inside the first foil tube is able to accommodate a component that is required in a much lower volume fraction in the finished mixture than the component in the large outerlying chamber. The chambers may be arranged coaxially, but the inner foil tube may also be offset from the axis. The use of foil tubes and partitions may also be combined so that, depending upon the intended use, it is possible to achieve any design of the chambers.
- All chambers preferably extend up to the cover, where each chamber is assigned its own first opening. All the chambers also preferably extend to the base.
- A head section is preferably provided, which is firmly connected to the cover and which has an outlet opening provided on a receptacle for a mixing tube for dispensing the filling material. The head section is preferably fabricated of a relatively rigid material so that the outlet opening does not get deformed when the filling material is dispensed.
- The outlet opening may be sealed (prior to use of the foil cartridge) by a closure.
- At least one channel for guiding the filling material to the outlet opening is formed between the cover and an inner wall of the head section. In the case of several chambers, a channel is preferably formed for each chamber, which advantageously runs separately up to the outlet opening in order to prevent mixing of the filling materials in the individual chambers within the foil cartridge. Because of the channels, the individual components and filling materials are also completely separated from one another even when the foil cartridge has been opened before exiting from the outlet opening.
- The connection between the foil tube and cover or base as well as between the cover and head section may be accomplished by adhesion or welding, in particular ultrasonic, laser or thermal welding.
- The head section and cover may also be connected by locking into place or by caulking. Naturally, a combination of these measures may also be utilized. All connections are preferably executed so that the chambers are tightly hermetically sealed.
- In a preferred embodiment of the invention, a discharge opening separate from the first opening is provided for each chamber. This offers various advantages for the filling process of the foil cartridges. For example, it is possible to fill the chamber via the first opening enough so that the channel up to the outlet opening is completely filled with the filling material. This makes it possible to minimize the first runnings, because the mixing ratio for multi-component cartridges corresponds to the desired mixing ratio at the very beginning.
- It is possible to seal adjacent first openings, discharge openings or filling openings with common closures.
- One or more foils, for instance a composite foil or monofoil, are preferably provided as the closure for both the first openings, the discharge openings and the outlet opening. The foils may be made, for example, of one or more layers of polyethylene, polypropylene, polybutylene terephthalate or ethylene vinyl copolymer and/or aluminum.
- The foil is preferably welded or adhered to the edge of the opening. A tear-off tab may be provided for ease of removal.
- A metal plate or an injection molded part may also be provided as a closure, in particular for the filling openings in the head section. These closures may also be sealed with the edge of the opening preferably by adhesion or welding.
- The closure may be placed directly on the respective opening.
- Several possibilities are conceivable for opening or removing the closure. For example, a foil may be designed in such a way that it may be pulled off as a whole and the discharge opening or the outlet opening is completely exposed after the foil is removed. However, a foil may also have one or more weakened zones along which the foil tears in a controlled manner due to the excess pressure applied by the dispensing device and which define the outlet opening or uncover the discharge opening. It is possible to produce the weakened zone in a very reproducible manner, for example, by laser removal.
- The closure, in particular the closure for the first openings, may be provided, for example, with the material information about the components of the filling material, a lot number or even the expiration date. It may also be used as the case may be to label the foil cartridge.
- In order to improve the filling process, the edge of the first opening and/or the filling opening may have a conical taper. The taper is used to center a filling lance and thereby produce a tighter closure between the filling lance and the edge of the opening.
- At least one lip is preferably configured on the edge of the first opening and/or the filling opening. The advantageously circumferential lip, or even a corresponding ridge, is used to strip off the filling material from the filling lance when retracting the filling lance. Several lips or ridges may also be arranged axially in succession in order to strip off the greatest possible portion of the filling material.
- Coarse or relatively large fillers may be used in the individual components of the filling materials, because the first opening may be designed to be large enough that it is possible to fill in such components without a problem. The size of the channels may also be simply selected so that coarser fillers may be used in the filling materials.
- It is possible to achieve long storage periods because the chambers are hermetically sealed and separated from one another and the leakage rate is virtually zero due to the design of the chambers.
- Independent of the number of components used, the outer geometry of the foil cartridge may be designed to be the same. This makes it possible to use one dispensing device for different types of filling materials.
- The outlet opening may also remain unsealed. In this case, the discharge opening is preferably sealed by a closure provided with a weakened zone, and when the dispensing pressure is applied when inserting a still sealed new foil cartridge into the dispensing device, the internal pressure exceeds the force required to open the weakened zone. In this way, it is possible to automatically open the newly inserted foil cartridge in a controlled manner.
- Because of the design of the cross-section of the channel and/or the cross-section of the first openings or discharge openings, it is possible to produce a throttling effect on individual filling materials from different chambers thereby allowing the quantity of the respective dispensed filling material to be adjusted very precisely. Flow differences in the case of different rheologies of the individual filling materials may also be equalized in this way.
- The following steps are executed in a method for producing a foil cartridge, such as described above: establishing at least one chamber by connecting the cover with the foil tube;
- filling the chamber with a filling material through the first opening in the cover; and sealing the first opening.
- The foil cartridge is fabricated completely prior to being filled. Even any base that may be present is already used so that the chambers are completely sealed with the exception of the first opening and possibly an additional discharge opening. The filling material is filled into the chamber as a second step, which may be carried out in another machine other than that used for the fabrication of the empty foil cartridge. After the filling process, the first opening is sealed and thus the foil cartridge is hermetically sealed.
- A head section described above with the receptacle for the mixing tube for dispensing the filling material may be firmly connected to the cover before the filling process or after the filling process.
- If the filling process is carried out after placement of the head section, the channels between the cover and head section are also preferably filled with the filling material.
- If the head section is positioned after the filling process, the filling process is carried out via the first opening, and the first opening is sealed after the filling process and before the head section is fastened.
- If the filling process is carried out after placement of the head section, the first opening and/or the discharge opening may remain open, and only the openings (filling opening and outlet opening) in the head section are sealed.
- If the cover has an additional discharge opening for each chamber, an additional filling opening is preferably provided flush with the first opening in the head section.
- The filling process takes place advantageously via a filling lance, which is inserted into the first opening in the chamber, wherein an immersed filling process is carried out. As the fill level increases, the filling lance is retracted little by little during the filling process. Therefore, it is possible to fill the chambers so they are free of air bubbles. The filling process may be supported by a vacuum or counter pressure. This is particularly useful if the channels are also supposed to be filled up to the outlet opening.
- The air in the chambers may escape through the discharge openings for example (if present). In the case of the filling process with a placed head section, it is also possible to design the filling opening in the head section with a smaller cross-section than the first opening so that even though the filling lance fits tight at the filling opening, the air is able to escape from the chamber during the filling process due to the excess size of the first opening.
- The foil cartridge is simple to open because it is possible to simply pull off the foil that is used as the closure without tools or it may be torn off in a defined manner with exertion of a certain force on the foil cartridge from outside from the dispensing tool. Because a defined opening always occurs, the forces required for the application process during opening and during dispensing of the filling material are always constant.

FIG. 1 shows afoil cartridge 100 in accordance with a first embodiment. Thefoil cartridge 100 in this case includes twofoil reservoirs 102 as well as a head section 104 (seeFIG. 3 ). Thehead section 104 is connected on an upper axial end to each of the twofoil reservoirs 102 that are arranged next to each other. - One of the
foil reservoirs 102 is depicted in greater detail inFIG. 2 . A first,outer foil tube 106 is subdivided by a partition 108 (seeFIGS. 6 and 7 ) into twoparallel chambers FIGS. 6 and 7 show, the twochambers partition 108. Instead of asingle partition 108,several partitions 108 could also be provided, which may extend in any desired manner through the cross-section of thefoil tube 106. - The
foil tube 106 and thepartition 108 inFIGS. 6 and 7 are fabricated of a single piece of foil. However, it would also be possible to use a foil tube with a closed circumference, for example produced by extrusion, and to introduce apartition 108 into the interior. Fastening thepartition 108 on thefoil tube 106 is carried out in this case by adhesion or welding using any suitable method. - The axial end of the
foil tube 106 facing away from thehead section 104 is sealed in this case by a base 114 (not shown). Thebase 114 here is a piece of foil, which is connected to the axial end of thefoil tube 106 and of thepartition 108 by adhesion or welding so that thechambers - On the axial upper end, the
chambers cover 116, which, like the base 114, is firmly connected to thefoil tube 106 and thepartition 108 by welding or adhesion. Thefoil tube 106,partition 108,base 114 and cover 116 delimit thechambers - However, several openings are configured in the
cover 116, in this case, afirst opening 118 for eachchamber discharge opening 120 that is separate from the first openings. Thecover 116 in this case is made of a relatively firm foil material. It may be more firm than the material that is used for thefoil tube 106. Thehead section 104 in this case is fabricated of a more firm material than thecover 116 and produces a dimensional stability for the entire axial upper end of thefoil cartridge 100. In particular, thehead section 104 makes sure that the diameter of the openings remains constant even when thefoil cartridge 100 is used in a dispensing device (not shown). - Openings are also configured in the
head section 104, specifically a central outlet opening 122 as well as a fillingopening 124 for everychamber outlet opening 122, the filling openings being respectively flush with thefirst openings 118 in thecover 116.FIG. 3 depicts the respective situation only for onechamber 112 of afoil reservoir 102. However, thehead section 104 has only onecommon outlet opening 122 for allchambers foil reservoirs 102. -
Channels 126 are configured between the inner wall of thehead section 104 and the upper side of thecover 116 and respectively guide from one of thedischarge openings 120 to theoutlet opening 122. - The
outlet opening 122 is arranged on a pipe-shapedreceptacle 128, which forms a receptacle for a mixing tube for dispensing the filling material accommodated in thechambers - The dividing
walls 130, which delimit thechannels 126 in the interior between the walls of thehead section 104 and thecover 116, extend directly to theoutlet opening 122 so that it is effectively partitioned into asmany channels 126 as chambers that are provided. - Before the
foil cartridge 100 is used, theoutlet opening 122 is tightly sealed by aclosure 132. In the case depicted here, theclosure 132 is a foil that has a weakenedzone 134 for everychamber channels 126 in the region of the outlet opening 122 (seeFIG. 5 ). - All the
chambers foil cartridge 100. Intermixing of the different filling materials in theindividual chambers - The filling
openings 124 are likewise tightly sealed by aclosure 136. Theclosure 136 in this case is also a foil, which is printed with the product name, the filling materials contained in theindividual chambers foil cartridge 100. - It is also possible to use a metal plate or an injection molded part as the
closure 136. In all cases, theclosure 136 seals the fillingopenings 124 completely tight so that filling material is not able to exit from thechambers - In the
head section 104, a fillingchannel 138 extends in this case from the edge of the fillingopening 124 directly to thefirst opening 118 in thecover 116. In the region in which the filling channel forms the edge of the fillingopening 124, the filling channel has aconical taper 140, which ends in acircumferential lip 142. Thelip 142 defines the region with the smallest cross-section of the fillingchannel 138. - When the
foil cartridge 100 is manufactured, first thefoil reservoir 102 is produced. To do so, afoil tube 106 made of a flat foil section or as a foil tube with a closed circumference is produced. Anypartitions 108 are fastened in thefoil tube 106. Thebase 114 is inserted at the lower axial end and adhered or fastened by ultrasonic, laser or thermal welding. Thecover 116 is also fastened on the opposing axial end. In the process, thepartitions 108 are also fastened on thebase 114 and cover 116 so that individually self-containedchambers first openings 118 and thedischarge openings 120 are still open. - Next the
head section 104 is firmly connected to thecover 116, for example, by adhesion or welding. - Now the
channels 126 between thecover 116 andhead section 104 are also configured. Theoutlet opening 122 is also still open, just like the fillingopenings 124. Thefoil cartridge 100 is now ready for filling as a prefabricated product. This may be carried out in a different machine than the manufacturing. - Now a filling lance (not shown) is inserted into the
respective chamber openings 124 and thefirst openings 118, and the specific filling material intended for thechamber chamber conical taper 140 causes the filling lance to be centered in the fillingopening 124 and makes sure that the fillingopening 124 is essentially sealed by the filling lance. The air escaping from thechamber discharge opening 120 and theoutlet opening 122. The filling lance is retracted little by little in the course of the filling process, wherein thelip 142 strips off excess filling material from the filling lance.Several lips 142 arranged axially in succession could be provided in the fillingchannel 138, wherein in this case only one is depicted. - The filling process is carried out until the filling material exits from the
discharge openings 120 and thechannels 126 are filled up to theoutlet opening 122. - The filling process may be supported by applying a vacuum to the
outlet opening 122 or establishing a counter pressure. - After the filling process is concluded, the
outlet opening 122 is tightly sealed with theclosure 132. In doing so, theindividual channels 126 are completely separated from one another. - The filling
openings 124 are also tightly sealed with theclosures 136. Thefirst openings 118 and thedischarge openings 120 remain unsealed in this example. - The
finished foil cartridge 100 may be inserted in this form into a dispensing unit, wherein the pressure that is initially applied makes sure that the weakenedzone 134 in theclosure 132 of the outlet opening 122 tears. Already at this point time, the filling material exits from allchambers - The
closure 132 could also be designed so that it is pulled off by the user before insertion into the dispensing device. - The shape of the
channels 126 and the size of thedischarge openings 120 depends upon the filling material used in thechambers openings 120 andchannels 126 are large enough for filling materials with larger fillers to flow out without being impeded or a throttling effect is realized for low-viscosity filling materials and/or those that are only required in small volumes. Each of thechannels 126 may be configured differently with this in mind. The variation may be achieved by the shape of thehead section 104 and the dividingwalls 130. - In the depicted case, a four-component cartridge is realized in which each of the
chambers foil reservoirs 102 contains a different filling material. The filling materials first come into contact with one another when exitingoutlet opening 122 and are mixed in the mixing tube placed there. - A second embodiment of a
foil cartridge 200 is depicted inFIGS. 8 to 12 . - The reference numbers already used are retained for components that are identical to those of the first embodiment.
- In this case, the
separate chambers second foil tube 206 being inserted into thefirst foil tube 106. In addition, as in the first embodiment, anotherpartition 108 is provided here, which is located between the wall of thefirst foil tube 106 and that of thesecond foil tube 206 so that three chambers are formed overall. It would also be possible to provide severalsecond foil tubes 206 or to further subdivide these with partitions. - As in the first embodiment, each of the
chambers first opening 118 in thecover 216. - This arrangement applies to both foil reservoirs 202 (see
