This application claims priority from Swiss Patent Application No. 1999 2315/99, which was filed on December 17, 1999, the entire disclosure of which is hereby incorporated by reference.

Technical field

The present invention relates to an adapter, an arrangement and a method for removing substances from multi-chamber tubular bags, a tubular bag packaging and a use of the adapter according to the preambles of the independent claims.

State of the art In general, tubular bag packaging is used with advantage wherever liquid, pasty substances are to be packed in small quantities and with a minimum of packaging material. The removal takes place after a deliberate destruction of the outer skin of the tubular bag packaging.

The advantages of this packaging technology have led to the fact that the components of multicomponent systems, in particular multicomponent adhesive systems, are now also packaged in tubular bag packaging, preferably in such a way that when mixing the packaged and coordinated amounts of the individual components, the correct mixing ratio is inevitable results.

Systems are known in this context in which two single-chamber tubular bags with the components of a two-component adhesive system via a connecting part, which at the same time acts as a removal adapter serves and brings the components together, are interconnected. The Hilti HIT HY-150 system and the adapters shown in documents EP 0665063A1 and BE 1008472A3, which are intended for removing substances from several single-chamber tubular bags, may be mentioned here as an example. All of these systems have the disadvantage that the coordinated amounts of substance are not captively connected to one another by packaging in individual single-chamber tubular bags and / or the packaging has disadvantageous dimensions, and the processing of the same special discharge devices with separate pressing cylinders per tubular bag, the pressing pistons of which are also synchronized with one another need, need. Such discharge devices are usually expensive to obtain, heavy and unwieldy.

US 3,323,682 shows two versions of a disposable cartridge packaging with several chambers, e.g. for the components of two-component adhesive systems, which has two foldable containers in its interior that form the chambers for the components. Although this cartridge contains the individual components in the desired proportions and in a captive form and can also be processed in commercially available hand presses, it does, however, cause a multiple of the packaging waste of tubular bag packs of the same content.

EP 0754633A2 discloses multi-chamber tubular bag packaging in which the components of a two-component adhesive, in contrast to the previously mentioned designs, are compactly and captively accommodated in separate chambers within a multi-chamber tubular bag. For processing, an end of the same formed by the chambers of the multi-chamber tubular bag is pulled through a central outlet opening of a removal device and then opened so that the components conveyed out of the chambers of the multi-chamber tubular bag exit gather in these chambers. An at least initially separate removal of components or the formation of a material flow with a certain distribution geometry from the removed components, for example for feeding it to a downstream static mixer, is not possible in this way.

Presentation of the invention

It is therefore an object to provide devices and methods for removing substances from multi-chamber tubular bags and tubular bag packaging which do not have the disadvantages mentioned above.

This object is achieved by the adapter, the arrangement and the method for removing substances from multi-chamber tubular bags and the tubular bag packaging according to the independent claims.

In one aspect of the invention, the adapter is designed to remove substances from multi-chamber tubular bags, in particular from

Double-chamber tubular bags, in such a way that the components removed from the chambers are guided separately in the adapter. For this purpose, the adapter has at least two passage channels for conveying the substances contained in the bag chambers through it and is designed such that the inner walls of the passage channels come into direct contact with these substances at least when the substances contained in the bag chambers are being discharged. This has the advantage that a controlled removal of the substances in the individual chambers without inevitable mixing of the same, as well as unmixed provision at different, precisely defined positions on the adapter for possibly downstream systems or elements such as delivery lines, discharge nozzles and / or mixer elements is made possible. Especially with certain static mixing elements, one is geometric precise introduction of the components to be mixed often of great importance for the mixing result. Various mechanisms are conceivable for conveying the components from the pouch chambers; in particular, the conveyance can take place as a result of gravity, due to the air pressure during suction and by generating an overpressure in the pouch chambers. A simple way to generate excess pressure is to press the tubular bag by hand or to pressurize it with a simple squeezing device, such as a commercially available hand press for sealant cartridges.

The substances removed from the chambers are preferably guided in the adapter in an essentially axial direction, based on the axis of the multi-chamber tubular bag to be connected to the adapter, and brought out in the axial direction.

The outlet openings of the passage channels are preferably arranged on the side of the adapter facing away from the multi-chamber tubular bag, such that the components removed from the bag chambers can emerge from the adapter on this side essentially in the axial direction with respect to the axis of the tubular bag. It is also advantageous if the outlet openings are also arranged essentially in a central area of the adapter. Particularly in applications in which application nozzles connected downstream of the adapter are used, a slim arrangement is thus created with an essentially axial extension, which simplifies application of the material to be discharged even in confined spaces.

The adapter advantageously has means for opening the tubular bag chambers, as a result of which a targeted opening as a result of puncturing or cutting through the outer skin of the tubular bag can be ensured. In a preferred embodiment these means are fixedly arranged in the adapter and are preferably designed such that the bag chambers of the tubular bag open to the passage channels of the adapter when the tubular bag provided with the adapter is first pressurized or when the adapter is placed and pressed onto the tubular bag. In another embodiment, these means for opening are movably arranged in the adapter, preferably in such a way that they can be inserted into the adapter from the outside. For this purpose, needle-shaped or dagger-shaped piercing or cutting tools or those with other shapes are suitable. Embodiments are particularly preferred in which an essentially simultaneous opening of at least two pouch chambers to at least two passage channels can be ensured. This is advantageously done by mechanically coupling movable opening means. It is of the greatest size, especially when used in connection with multi-component adhesive systems and mixing elements connected to the adapter

It is important that all components are provided in the correct proportions from the first moment, since only a precisely defined mixture of components leads to the desired adhesive properties.

If means for further processing of the removed materials are to be connected downstream of the adapter, it is advantageous if the adapter has connecting means for connecting downstream elements or system components, in particular mixers and / or nozzles. Advantageously, these connecting means include spoilage, but all other known fastening methods are also conceivable, such as bayonet locks, snap locks, force-fit plug-in connections or adhesives. In addition, the connection means can also include other functional elements, such as seals. In yet another preferred embodiment of the invention, the adapter is designed such that at least two of the components removed from the bag chambers are brought together in the adapter in the region of its outlet, and in particular that these components are mixed in this region.

The adapter is preferably produced from a plastic, in particular from a plastic with a low adhesive force compared to multi-component adhesives. This has the advantage that mechanical removal of hardened adhesive residues at the outlet of the adapter is simplified. It is also preferred if the adapter is produced by injection molding, since this results in particularly low production costs for large quantities.

In another aspect of the invention, an arrangement for removing substances from tubular bags comprises an adapter as described above and at least one means for bringing together the components removed from the bag chambers. These means can be, for example, dispensing nozzles or mixing elements, in particular static mixers.

In a preferred embodiment, the arrangement further comprises a squeezing device for the multi-chamber tubular bag. All devices are conceivable that are able to generate an overpressure in the chambers of the tubular bag, such as e.g. axially acting cylinder presses with a pressure ram and a receiving tube, radial pressing devices or pressurized containers into which the tubular bag can be inserted.

In another aspect of the invention, a tubular bag packaging comprises an adapter or an arrangement as described above and a multi-chamber tubular bag, in particular a double-chamber tubular bag. This tubular bag can be firmly connected to the adapter, for example by gluing or welding. Among other things, this has the advantage that there is no need to manually put the adapter on the tubular bag, the adapter is captively attached to the tubular bag, and the user can rule out possible incorrect positioning of the bag chambers in relation to the passage channels. The seal between the adapter and the tubular bag outer skin, and thus also the seal between the passage channels, can also be ensured in this way. In a preferred embodiment, the passage channels in the adapter are connected to the bag chambers in the unopened state of the tubular bag packaging, ie the bag chambers are open towards the passage channels and the outlet openings of the passage channels are closed.

This is advantageously carried out by means of closures, it being preferred that these closures be reclosable and in particular that they include screw closures so that, in the event of an interruption in removal or a change in production, the used tubular bag packaging can be closed again for temporary storage. In particular, it is desirable that the reclosable closure means are connected captively to the adapter.

It is also preferred if the outlet openings of the passage channels of the adapter are closed by one or more removable or destructible foils, in particular peelable metal foils. Combinations of foils and reclosable closure means are also conceivable, such as a metal foil as a seal for the outlet openings of the unused packaging and a screw cap for closing the packaging after use. In a further aspect of the invention, the adapter described above for filling multiple chamber tubular bags, in particular double chamber tubular bags, used.

A last aspect of the invention relates to a method for removing substances from multi-chamber tubular bags, in particular for removing substances from double-chamber tubular bags, the substances removed from the bag chambers being passed through the adapter in an adapter through at least two passage channels arranged in the adapter, essentially separated from one another be brought into direct contact with the inner walls of the passage channels.

WAYS OF CARRYING OUT THE INVENTION A preferred embodiment of the invention is shown in FIG. 1. As can be seen from this sectional view, the adapter 1 has two separate through-channels Ha and 11b, which extend axially through them and are provided for the separate transport of the substances contained in the chambers of a double-chamber tubular bag. As can be seen, the adapter shown has a flange-like configuration on the inlet side, which forms an axial shoulder 6. This shoulder can be used as an axial stop surface when fastening the adapter 1 in front of the cylinder of a pressing device with the aid of an axial pressing device, e.g. a union nut with screw thread or bayonet lock. On the outlet side, the adapter 1 has an external thread 7 as a fastening means for downstream elements such as Mixer and / or discharge nozzles. In addition, the thread runout is designed here in such a way that it forms a socket on the outlet side of the adapter 1, which provides both axial 8 and radial sealing surfaces 9.

As can also be seen, the adapter 1 has an edge 12 on the entry side, which on the one hand is the centering when using a

Squeezing device can serve, on the other hand includes the end of the tubular bag and when the tubular bag is open this end stabilized radially. This edge also serves the purpose of sealing the open end to the outside. Depending on the viscosity of the materials to be processed, this sealing can take place by means of the radial contact pressure as a result of pressurization and / or, for example, by gluing or welding. Certain sealing elements such as, for example, radially encircling rigid or elastic sealing edges or grooves 20 can also be used, as a result of which the sealing effect is improved. As can be seen from FIG. 2, the space enclosed by the edge 12 opens into the depressions 13a and 13b, which in turn open into the passage channels Ha and 11b. The depressions 13a and 13b are separated from one another by a web 14, which has a further depression 15 in its center for receiving the closure clip of a tubular bag packaging. The depression 15 ensures that the tubular bag outer skin can rest against the web 14 and thus the depressions 13a and 13b are sealed against one another. Here too, depending on the viscosity of the materials to be processed, sealing takes place by means of the axial contact pressure as a result of pressurization and / or, for example, by gluing or welding. Here too, certain sealing elements such as rigid or elastic sealing edges or lugs can be used, which improves the sealing effect. In addition, designs are also conceivable in which the depressions 13a, 13b are formed by the passage channels Ha, 11b.

As shown in FIGS. 1 and 2, the adapter 1 has two through-channels Ha and 11b with different cross-sections which extend axially therethrough and on the exit side in a central region form outlet openings 16a, 16b which prevent the through-passage the passage channels Ha, 11b cause substances guided in the axial direction. The targeted formation of the passage channel cross sections gives the possibility, depending on the viscosity and the desired quantity ratios of the substances contained in the bag chambers to influence the pressure losses through each passage channel in such a way that with the same overpressure in the bag chambers, e.g. by using a commercially available hand press, there is a discharge with essentially constant quantity ratios over the entire discharge time results. However, there are also designs with through-channels Ha, 11b with cross sections of the same size. The exit from the

Outlet openings 16a and 16b in the axial direction and their arrangement in the center of the adapter 1 is particularly advantageous when it comes to assembling a slim arrangement of discharge device, adapter and downstream elements such as dispensing nozzle and / or mixer, since this results in an arrangement with the essential axial extent can be realized. If, on the other hand, the substances contained in the bag chambers are only to be removed and / or passed on separately, it may also be advantageous to provide the outlet openings 16a, 16b at a greater distance from one another on the adapter 1, both in the axial and in the radial position , It is also conceivable to provide the adapter 1, optionally with additional further elements such as mixers and / or discharge nozzles, as an individual part or also as a tubular bag packaging with a multi-chamber tubular bag. In this case, the tubular bag and adapter 1 can be firmly connected to one another by gluing or welding and form an inseparable unit. This has the advantage, among other things, that there is no need to manually place the adapter 1 on the tubular bag and the adapter 1 is captively connected to the tubular bag. An otherwise possible manual incorrect positioning of the bag chambers to the passage channels is prevented and the desired sealing between the adapter and tubular bag outer skin, and thus between the passage channels and to the outside.

FIGS. 3 and 4 show designs of the adapter from FIGS. 1 and 2, which have means for opening the tubular bag chambers. The adapter 1 in FIG. 3 has opening elements 17 which are arranged in the adapter and which, when the adapter is pressed onto a bulging tubular bag or when a tubular bag arranged with the adapter is pressurized, pierce or cut through the outer wall of the tubular bag. The adapter 1 in FIG. 4 has lancing elements 18 which are movably arranged in the adapter and which are introduced axially from the outside into the adapter 1, as a result of which the outer skin is pierced by one with the

Adapter arranged tubular bag can be effected. In the example shown here, the lancing elements 18 are fastened on a common support ring 19, as a result of which the axial insertion of the lancing elements 18 into the adapter 1 for piercing the outer skin of the multi-chamber tubular bag and the opening of the chambers of the same takes place simultaneously. This is particularly important if the substances to be removed from the bag compartments are the components of a multi-component adhesive system, since if the opening is delayed, incorrect gluing can occur temporarily due to incorrect mixing ratios of the components. After the piercing, the piercing elements 18 remain in the adapter until the tubular bag chambers have been completely emptied, in order to prevent substances from escaping and / or air from entering through the insertion openings for the piercing elements.

In the embodiments shown in the figures, the passage channels are arranged exclusively in such a way that the individual substances emerge unmixed and separately from the adapter, so that they can then be transported separately or subsequently to be brought together and / or mixed. However, adapter designs are also conceivable for special applications in which the substances removed from the bag chambers are brought together and / or mixed in the region of the outlet of the adapter. In this case, however, care must be taken to ensure that the merging or mixing zone is easily accessible from the outside in order to enable simple mechanical cleaning thereof. This is particularly important when the components of curing multicomponent adhesives are brought together or mixed in this area.

FIG. 5 shows a tubular bag packaging consisting of a double-chamber tubular bag 10 and an arrangement consisting of the adapter 1 according to FIG. 3 and a downstream static mixer 21 with an integrated dispensing nozzle 22, which is arranged in a pressing device 23. As can be clearly seen, the tubular bag 10 is located in the receiving tube 24 of the pressing device 23 and is pressurized by the stamp 25 of the pressing device 23. The adapter 1 enters the receiving tube 24 and is centered in it by the edge 12. The adapter 1 is pressed axially with a union nut 26 against the receiving tube 24, against which it rests with the shoulder 6. The closure clip 27 of the end of the tubular bag 10 on the adapter side lies in the recess 15 of the separating web 14 and thereby centers the end of the tubular bag 10 in the adapter inlet. As a result of the pressurization, the tubular bag is pressed axially against the separating web 14 and radially against the radial inner surface of the edge 12 and the radial sealing groove 20 arranged thereon, thereby sealing the depressions 13a and 13b against one another and against the interior of the receiving tube 24. At the same time, the

The outer skin of the tubular bag is pressed into the recesses 13a and 13b and thereby pierce elements 17 so that the connection between the two chambers 28a and 28b of the tubular bag 10 and the passage channels Ha and 11b is established. Downstream of the adapter is the static mixer 21, which is placed on a connecting piece from which the through-channels Ha, 11b emerge from the adapter and is fastened to it by means of a union nut 29. The seal between the connection piece and the mixer, as well as the exact positioning thereof, is ensured by axial 8 and radial contact surfaces 9 at the threaded outlet of the connection piece. If the punch 25 of the squeezing device 23 continues to be pressed in the direction of the adapter 1 when the bag chambers are open, an overpressure arises in the chambers 28a, 28b of the tubular bag 10, which corresponds to the pressure in the

Bag chamber 28a located substance in the recess 13a and then in the passage channel Ha. The substance in the bag chamber 28b is conveyed into the recess 13b and then into the passage 11b. If the pressurization continues, both substances are conveyed separately through the passage channels Ha and 11b and exit the adapter 1 at a precisely defined radial and axial position and enter the mixer 21. There they are mixed with each other and then via the am

Mixing nozzle 22 is applied at the desired location. If the removed and mixed substances are the components of a two-component adhesive system, a longer interruption in work leads to the adhesive in the mixer 21 curing, but not in the adapter 1. It is then only necessary to restart the discharge operation, to replace the mixer 21 downstream of the adapter 1 and to remove any hardening at the adapter outlet. Until then, the old mixer can be used as a sealing cap for the temporary storage of the opened tubular bag packaging. Even if I'm here In the example described, a mixer 21 with an integrated dispensing nozzle 22 is described as an element downstream of the adapter 1, the illustration given above can also be transferred to the sole use of a merging dispensing nozzle. If adapters 1 are used in which the components are still brought together and possibly mixed in their outlet area, they are designed in such a way that, after the removal of a possibly downstream element, the joining or mixing zone is easily accessible for mechanical cleaning , In this case, a stopper formed from hardened adhesive could serve as a stopper for the used tubular bag packaging until it is mechanically removed.

The combination of a multi-chamber tubular bag 10 and an adapter 1 with fixed opening elements 17 used in FIG. 5 is suitable both for loose adapters and loose tubular bags and for tubular bag packaging with adapters firmly attached to the tubular bag. It can also be used on an adapter

1 with movable means for opening 18 the bag chambers

28a, 28b transmitted. It is also conceivable to design a tubular bag packaging with a multi-chamber tubular bag 10 and an adapter 1 according to FIG. 1 in such a way that the depressions 13a, 13b and the passage channels Ha, 11b are already connected to the bag chambers 28a, 28b in the unopened state of the tubular bag packaging stand and the packaging is opened by exposing the outlet openings 16a, 16b of the through-channels Ha, 11b on the adapter 1. However, this presupposes that tubular bag 10 and adapter 1 are firmly connected to one another and that the spaces connected to the bag chambers 28a, 28b are sealed both from one another and from the outside. This can advantageously be achieved by gluing or welding, which in particular then It is particularly simple if both adapter 1 and tubular bag 10 are made of a similar material. The outlet openings 16a, 16b on the adapter 1 of such a tubular bag packaging can be closed in a variety of ways. Since the adapter 1 advantageously has fastening means 7 for fastening downstream elements, it makes sense to design the closure elements in such a way that they use these fastening means 7. Screw closures, for example, are particularly advantageous as closure means, since they are reclosable and therefore also make it possible to close used packaging. It is also conceivable to close the outlet openings 16a, 16b with one or more foils which can be pierced or removed to open them. These have the advantage that a used packaging can be clearly distinguished from a new packaging and that a hermetic seal of the unused packaging is ensured. Furthermore, it is possible that when the tubular bag packaging is closed, the through-channels Ha, 11b end as blind holes in the outlet-side nozzle of the adapter 1 and are opened by cutting off the outermost part thereof. This would also ensure a hermetic seal. A particularly advantageous solution, however, is a combination of reusable and destructible closure means, because this ensures good storage of the goods stored in the tubular bag packaging by hermetic sealing and, on the other hand, a used packaging can be closed again for the intermediate storage. If, for example, a removable metal foil is used in combination with a screw cap, there is also the advantage that the foil during the

Transport and storage of the new packaging by the Screw cap is protected against accidental damage.

If the tubular bag packaging is designed in such a way that tubular bag 10 and adapter 1 are firmly connected to one another and the passage channels are connected to the bag chambers, it is also possible to produce unfilled tubular bag packaging and then or later by connecting a filling device to the passage channels of the Fill the adapter and then close it on the adapter. In this way, universal packaging could be produced which can be filled with simple filling devices and which enables economical packaging even in small quantities. Figures 6a-6e show different embodiments of double-chamber tubular bags, the structure of which can also be transferred to tubular bags with more than two chambers. The multi-chamber tubular bags shown in FIGS. 6a and 6b have bag chambers lying next to one another, which have a common single or double connecting wall. The tubular bags shown in FIGS. 6c and 6d are designed in such a way that the tubular bag chamber with the smaller volume is essentially arranged in the chamber with the larger volume and the walls of which touch at least one point. It is also possible that part of the outer wall of the larger bag chamber also forms part of the outer wall of the smaller bag chamber or parts of its outer walls jointly form a double-walled section of the outer wall of the tubular bag. The tubular bag in FIG. 6e, on the other hand, shows two bag chambers with their own bag chamber walls, which are connected to one another by a common tubular bag envelope. In addition to the configurations shown are of course also

Combinations of the same with two or more bag compartments are possible. All multi-chamber tubular bags is on the other hand, in common that the pouch chambers are connected to one another by their adjoining walls, which inevitably leads to a substantially uniform pressurization of all pouch chambers when pressurized, that all chambers of a pouch have essentially the same longitudinal extent and that at least one end of the pouch is closed essentially centrally, for example by a metal clip, which serves as a common closure element for all bag compartments. The centrally closed end preferably forms the adapter-side end of the tubular bag. As can be seen from the examples, the quantities of substance packaged in multi-chamber tubular bag packaging are practically not subject to any restrictions in terms of their quantity ratios, which makes them suitable for a wide variety of applications. Even if an application for multicomponent adhesive systems was discussed as the preferred field of application of the invention in the description of the exemplary embodiments, it can also be used for all other liquid to pasty substances, and preferably for combinations of substances which are to be provided in certain quantitative ratios and in particular for reactive systems. Examples include food formulations, single-component adhesives with curing accelerators, coatings or sealing compounds.

While preferred embodiments of the invention are described in the present application, it should be clearly pointed out that the invention is not restricted to these and can also be carried out in other ways within the scope of the following claims.
