Definitions

  • the invention relates to a cartridge for holding and processing building materials such as sealants, silicones or adhesives.
  • this cartridge is usually made as a disposable product consisting of a plastic tube with an integral, closed cartridge head, into which the mass to be processed is filled and then the end of this cartridge is tightly closed with a cartridge base.
  • the cartridge In order to remove the building material mass from the cartridge, the cartridge is inserted into a squeezing tool in the form of a cartridge gun or similar and is acted upon by, for example, a manually mechanically operated pressure stamp, which rests on the movable cartridge base inside the cartridge and removes the viscous mass of the building material pressed out of the cartridge for processing.
  • a manually mechanically operated pressure stamp which rests on the movable cartridge base inside the cartridge and removes the viscous mass of the building material pressed out of the cartridge for processing.
  • the rest of the mass that is still in the cartridge can be pushed back to the rear end of the cartridge using the outlet connection and removed from the rear of the cartridge.
  • the outlet connection inserted as an insert part into the cartridge cylinder as well as the piston for squeezing the building material out of the cartridge can thus be detached from the cartridge cylinder, which can then be used again. Only the outlet connection and the piston are not reusable, as these are contaminated with the pressed building material mass.
  • tubular bag guns have been created as special pickup and discharge devices that enable the mass to be removed from these transport tubes. This is an improvement over disposable cartridges in that the volume of waste after squeezing out the cartridges is reduced The remaining hoses contained in the building material mass are significantly lower than is the case with disposable cartridges.
  • the disclosed invention of the EP 3 936 454 A1 relates to a cartridge cap mountable to a distal end of a cartridge body for use with an extrusion gun.
  • a plurality of rods extend longitudinally from an inner surface of the cap body, at least one rod of which is adapted to pierce a flexible bag.
  • a paper-based cartridge cylinder is also disclosed.
  • two aspects are disadvantageous here, on the one hand, the cartridge cap inserted into the cartridge, which offers no space for the compressed tubular bag, and on the other hand, the cartridge base, which, precisely because of its rounded transition area to the inner wall of the cartridge body, does not ensure secure guidance of the tubular bag to be compressed can.
  • the task of the cartridge according to the invention is, on the one hand, to create a cartridge for building material masses that is suitable for both professional and amateur use, which advantageously combines the advantages of disposable cartridges with the advantages of tube storage of the building material masses to be processed.
  • the environmental compatibility of these products should be significantly improved by increasing the proportion of usable and processed building material mass on the one hand and a lower volume of waste when using the present cartridge on the other hand, at least through better separation of the constructive components of the cartridge.
  • this should also be achieved while fully maintaining the functionality and clean emptying of the tubular bag.
  • the cartridge base is therefore not designed as a simple flat pushing base, but rather has a circumferential jacket which is arranged parallel and tightly fitting to the cartridge cylinder itself in alignment with the cartridge head.
  • this jacket is designed as a cup, that is, it includes, on the one hand, the jacket that rests on the inner wall of the cartridge cylinder as well as a base area, which either lies flat on the cartridge base and is formed over the entire surface thereof or already forms the cartridge base itself.
  • the cartridge base is not designed as a flat disk but rather as a kind of cup with a jacket area raised on the inner wall of the cartridge cylinder.
  • this special design of the cartridge base or the combination with a cup insert can ensure that the tubular bag to be compressed lies within the jacket area of this specially cup-shaped cartridge base or cup insert, which lies closely against the cartridge cylinder wall, especially at the beginning of the compression process fits in and the first folded layers of the compressed tubular bag rest inside this cup.
  • tubular bag folds up from below due to the compression so that the compression first takes place into the cup-shaped cartridge base.
  • This also has the effect that this cartridge base or cup insert is filled with respect to its jacket area, which runs parallel to the cartridge cylinder wall, and thus an even better fit on the inner wall of the cartridge cylinder is achieved.
  • the collapsing tubular bag presses the casing of the cartridge base against the cartridge cylinder and thus additionally prevents the emptied tubular bag from getting into the gap here.
  • this cartridge base is also a cup insert, in which, starting from a cardboard disk, for example, the radius of which exceeds the inner radius of the cartridge cylinder by an amount that later forms the jacket height, this disk is formed into a cup by deformation, the bottom surface of which is then forms the piston surface required for compression of the tubular bag.
  • the cartridge cylinder has a radius of 2.5 cm, with a radius of approximately 4.0 cm a cup insert with a simultaneous piston function would be formed by forming with a cup wall height of approximately 1.5 cm, with which the piston is secure is guided in a sliding manner on the inner wall of the cartridge cylinder and the tubular bag is also received in a compressed manner.
  • the cup wall height is advantageously matched to the material of the emptied, compressed tubular bag.
  • the cartridge base it is also possible for the cartridge base to be supplemented with a ring-shaped cup jacket or a cup-like attachment, so that this does not have to be designed in the same way as the stable cartridge base on Because it is inserted into the cartridge cylinder, it must be designed to be stable and resilient, since this is where the pressure is exerted.
  • cup-like insert or annular cup jacket attached to this cartridge base can also be made significantly less stable, since, as explained, it receives additional stabilization from the emptied tubular bag folded into this cup. It has been found that even very thin paper as cup-like inserts or attached annular cup jacket already have the desired effect, namely to prevent the tubular bag from penetrating into the annular gap space between the displaceable cartridge base and the cartridge cylinder.
  • a design is also provided in which the cup-shaped attachment or attachment on or on the cartridge base is so thin that it folds up when it reaches the cartridge head of the cartridge cylinder and thus the tubular bag is completely compressed and emptied and therefore does not represent an obstacle Completely empty the tubular bag.
  • the jacket of this cup-like attachment or attachment on the cartridge base can also be pulled higher, since it does not represent an obstacle to the final compression of the tubular bag in the cartridge cylinder, provided it is so thin that it can also be used like the tubular bag itself At the end of emptying the tubular bag is folded into the cartridge head.
  • the cartridge head is provided in a special design according to the invention so that it has a height into which the compressed tubular bag can be completely pressed.
  • the flat face of the head does not lie flat against the front edge of the cartridge cylinder, but special spacers are provided that hold the cartridge head lift from the upper edge of the front end of the cartridge cylinder and create a higher receiving space so that the emptied, folded tubular bag is completely accommodated in the cartridge head.
  • the cartridge according to the invention therefore has, on the one hand, a cartridge cylinder which is made of environmentally friendly material.
  • the aim here is in particular to use a cardboard tube, although other materials, such as compostable recycled plastics, are also considered suitable.
  • This central structural element of the cartridge cylinder is connected at the end to a cartridge base as a sealing, movable piston element and at the front or end to a detachably attachable cartridge head with an outlet connection.
  • the building material mass is arranged in a movable tubular bag in the cartridge.
  • the cartridge according to the invention namely the tubular bag in which the building material mass to be processed, for example a silicone or sealing compound, is contained, a cartridge cylinder that encloses this tubular bag as tightly as possible, the cartridge base which can be moved in the cartridge cylinder as a sealing, displaceable piston element and the cartridge head attached to the front with outlet connection and outlet opening, which usually has an attached thread for attaching a nozzle.
  • the cartridge according to the invention namely the tubular bag in which the building material mass to be processed, for example a silicone or sealing compound, is contained, a cartridge cylinder that encloses this tubular bag as tightly as possible, the cartridge base which can be moved in the cartridge cylinder as a sealing, displaceable piston element and the cartridge head attached to the front with outlet connection and outlet opening, which usually has an attached thread for attaching a nozzle.
  • These four elements are designed to be separable from each other, since the tubular bag is
  • a cartridge is formed that resembles conventional disposable cartridges in its exterior, since it has a closed, stable base body in a cylindrical design, which makes it possible to insert this cartridge, for example, into a conventional cartridge gun.
  • An essential aspect of the present invention is that, on the one hand, there is an environmentally friendly product that can be recycled separately, but at the same time the advantageous aspects of the disposable cartridges currently used in terms of trade and handling are retained. It is therefore a product that can be stored, transported and used like a disposable cartridge; the presentation at the point of sale, for example a hardware store, as well as the product design, the application of product information and advertising material on the packaging are not included more possible as for a disposable cartridge.
  • the cartridge according to the invention can be purchased in the usual way, for example in a hardware store.
  • the tubular bag containing a building material mass, for example a sealing compound, is located in the cartridge cylinder.
  • the container is closed by the cartridge base inserted at the end and the cartridge head attached at the front.
  • a feed rod with a pressure stamp is pressed against the cartridge base serving as a piston and thus the piston-like cartridge base is moved into the interior of the cartridge and, in the case according to the invention, pressed onto the tubular bag. This is pushed onto the cartridge head and pressed, with the cartridge head being supported by a holder that is an integral part of the cartridge gun.
  • the cartridge according to the invention is clamped between this receptacle for the head of the cartridge and the pressure stamp for engagement into the interior of the cartridge cylinder.
  • the tubular bag is inserted into the cartridge head and at the same time the removable cartridge head is pressed against the cartridge cylinder when the building material mass is pressed out of an outlet opening in the cartridge head.
  • the cartridge head is not firmly connected to the cartridge cylinder as a detachable component and can be removed from the cartridge cylinder.
  • the cartridge according to the invention has the advantage that by pulling off the cartridge head, the hardened building material mass, which usually hardens in the upper section of the tubular bag into the spout of the cartridge head, can also be removed. This means that when the cartridge head with nozzle is removed, the hardened building material mass, for example a sealing compound such as silicone, is located in this upper frontal section of the cartridge according to the invention.
  • the hardened building material mass for example a sealing compound such as silicone
  • the cartridge base which serves as a piston, can be moved back into the cartridge towards the cartridge head by pushing the pressure stamp rod into the cartridge cylinder accordingly so that the building material mass can be pressed out of the cartridge head again.
  • this pressure stamp is retracted and the emptied cartridge can be removed from the cartridge gun and dismantled into individual modules.
  • the cartridge head is removed and the hardened remaining building material mass is removed from this cartridge head with the compressed tubular bag attached to it.
  • This tubular bag with the remains of the hardened building material remaining in the cartridge head can be disposed of separately.
  • the cartridge base as a piston element and the cartridge head. Both elements can, for example, be made from a recyclable plastic.
  • the cartridge cylinder which can be made as a cardboard tube, for example. This is then, in particular, a structural element of the present cartridge that can be easily reused, since such a cardboard tube can easily be recycled.
  • the cartridge cylinder 2 shown is ideally made of paper or cardboard, but can also be made of plastic or another material.
  • a piston-like cartridge base 4 and a cup insert 19 are inserted into this cartridge cylinder 2, both of which are also ideally made of paper/cardboard, but can also be made of plastic or another material.
  • Cartridge base 4 and cup insert 19 can also consist of one part, or can be assembled or glued together, that is, in this case the cup insert 19 is an integral part of the cartridge base 4, with the jacket forming the cup extending from the cartridge base 4 into the cartridge cylinder 2 extends and rests against its inner wall.
  • the cup insert 19 is crucial for the error-free functioning of the combination cartridge.
  • the cup insert 19 is designed so that its open side faces the inner wall of the cartridge cylinder 2 and lies very close to it. As a result, when the tubular bag 5 is pressed out, it brushes close to the sleeve wall, prevents the tubular bag film from pushing past the cartridge base 4 and accommodates the folding tubular bag film in its cavity.
  • the tubular bag 5 is located inside the cartridge cylinder 2, which is closed with the cartridge head 3.
  • the cartridge head 3 is removable because the end user can use the cartridge head 3 in the design according to the Figures 1 and 2 must be removed before use, then cut open the foil bag and then put the nozzle attachment back on.
  • the cartridge head 3 should also be freely removable after emptying, for example in order to be able to dispose of the cartridge separately according to individual components.
  • any standard spray nozzle is screwed on, the cartridge 1 is inserted into a commercially available cartridge gun and processed like a commercially available cartridge.
  • spacers 18 integrated in the cartridge head.
  • the nozzle attachment sits on the sleeve up to these spacers.
  • an enclosed cavity 20 is formed above the front edge of the cartridge cylinder 2, in which the compressed tubular bag 5 collects and can thus be easily removed together with the head part of the cartridge head 3 for waste separation.
  • a dome 21 in the cartridge head 3 is another smaller cavity above the first cavity 20, which the spacers form. This dome 21 allows the edge of the tubular bag film to spread out at its opening without blocking the passage of the threaded piece.
  • this cartridge has particular advantages of this cartridge are that the individual parts are very easy to separate after use, thus enabling the best possible waste separation. The proportion of residual waste is minimized as much as possible.
  • the squeezed one As described, the tubular bag 5 has collected in the cartridge head 3 after it has been completely emptied and can be removed together with it and disposed of with residual waste. Then all that remains is the sleeve, piston or piston disk and cup, which ideally consist of paper/cardboard and are not contaminated with product residue.
  • FIG 3 the basic structural components of the invention are shown next to each other in an alternative design.
  • the basic element of the cartridge cylinder 2 is shown, this cartridge cylinder 2 being shown as an open design with an upper and lower cartridge cylinder opening 15 and 16 in this design.
  • the tubular bag 5 to be accommodated is shown, which also has an upper and lower tubular bag end and its dimensions are adapted to the shape of the cartridge cylinder 2, or the cartridge cylinder 2 is adapted to the shape of the tubular bag 5.
  • the cartridge base 4 is to be inserted into the lower cartridge cylinder opening 16 to close the cartridge cylinder 2 after the tubular bag 5 has been inserted here, which is explained in more detail in the further figures.
  • the cup insert 19 according to the invention is not shown here.
  • cartridge head 3 according to the invention is shown, which in this alternative design has perforation mandrels 6 on the underside, which perforate the tubular membrane when the tubular bag 5 is appropriately compressed in the cartridge cylinder 2 and thus allow the building material 17 to escape into the cartridge head 3.
  • the cartridge head 3 is characterized by structural elements that enable it to be placed on the upper cartridge cylinder opening 15.
  • the cartridge head jacket 12 can be seen, which engages on the inside in the upper cartridge cylinder opening 15 and here leads to the cartridge head jacket resting against the inner surface of the cartridge cylinder.
  • the cartridge head 3 is held in the cartridge cylinder 2 by a circumferential cartridge head flange 14 which rests on the upper edge of the upper cartridge cylinder opening 15.
  • the building material 17 entering the cartridge head 3 is transferred into an outlet connection 7, at the upper end of which a grommet thread 13 is attached, onto which a grommet (not shown) can then be screwed.
  • this grommet thread will have to be cut open so that the building material 17 can emerge and then allow the building material to exit from the cartridge head 3 through the attached grommet.
  • FIG. 4 shows an exploded view of the structural elements as just described. It can be seen here that the tubular bag 5 is already largely inserted into the cartridge cylinder 2 and only protrudes from the cartridge cylinder 2 with its lower tubular bag end 11. This makes it clear that By placing the cartridge base 4, this lower tubular bag end 11 is completely inserted into the cartridge cylinder 2. Further loading of this cartridge base 4 with a pressure stamp 8 in the pushing direction 9 results in a further displacement of the tubular bag in the cartridge cylinder, with the tubular bag basically being freely movable in the cartridge cylinder 2.
  • the tubular skin of the tubular bag 5 is perforated in the area of the upper end of the tubular bag 10 when it is inserted into the cartridge head jacket 12.
  • the building material 17 can be inserted into the cartridge head 3 are pressed in and transferred via the outlet connection 7 into a nozzle (not shown).
  • the cartridge head jacket 12 has an essential function in guiding the tubular bag 5 into the cartridge head 3 and also has a sealing function relative to the inner wall of the cartridge cylinder 2, so that building material only flows from the tubular bag 5 into the cartridge head 3 and here into the Outlet connection 7 and the grommet, not shown, is pressed.
  • FIG. 5 in turn now shows a further step in the use of the cartridge according to the invention.
  • the pressure stamp 8, which is structurally part of a cartridge gun, which is not shown here, has been further inserted into the cartridge cylinder 2 and has thereby moved the cartridge base 4 from the lower cartridge cylinder opening 16 towards the upper cartridge cylinder opening 15.
  • This movement causes the tubular bag 5 to compress in the cartridge cylinder 2, whereby the tubular bag 5 is pressed upwards towards the cartridge head 3 and into the cartridge head jacket 12.
  • the building material 17 is discharged from the cartridge head 3, which also means that when residual building material 17 hardens in this cartridge head 3, the use of the cartridge 1 is not yet finished.
  • the cartridge head 3 is lifted out of the cartridge cylinder 2 again, the hardened building material 17 in the cartridge head 3 is also lifted out of the tubular bag 5 and, for example, the remaining building material 17 in the tubular bag 5 is thereby exposed again. Since the freely removable cartridge head 3 allows access to the building material 17 hardened in the cartridge head 3, it is therefore easily possible to free the cartridge head 3 from the hardened building material 17, since this is usually present as a hardened piece of building material and can be easily removed can be.
  • both the cartridge head 3 and the tubular bag 5 are freed from the rest of the hardened building material 17, which acts as a stopper, it is easily possible to place the cartridge head 3 back on the cartridge cylinder 2 and by further inserting the pressure stamp 8 over the The toothed rack of the cartridge gun in turn compresses the tubular bag 5 to such an extent that the building material 17 can emerge from the outlet port 7 on the top side as before.
  • This procedure can in principle be carried out until the building material 17 has been completely consumed, with a significant positive aspect being that the hardened building material 17 can be easily removed from the cartridge head 3 and also from the tubular bag 5 in this way and separately can be disposed of. Nevertheless, the cartridge 1 can be completely emptied, whereby after the last remnants of building material 17 have been removed, only the cartridge head 3 with the fully compressed tubular bag 5 can be removed and the parts can be disposed of in different ways.
  • the cartridge head 3 can, for example, be recycled from a plastic, whereas the compressed tubular bag 5 and the rest of the building material 17 are disposed of separately.
  • the cartridge base 4 can also be completely pushed out of the cartridge cylinder 2 and, if it is a plastic body, can also be recycled. Ultimately, all that remains is a completely free and uncontaminated cartridge cylinder 2, which in turn can be recycled, for example in waste paper, or can be used for other purposes.
  • the crucial improvement here is that the cartridge 1 behaves in the same way after use Figure 1 and 3 can be disassembled into all individual parts and disposed of separately without causing any disadvantages in use.
  • the presentation and storage as well as the application are basically analogous to a disposable cartridge.
  • the positive aspects of disposal are not included in any form with a disposable cartridge.
  • the complete consumption of the contents of the tubular bag 5 is also a significant advantageous aspect, since this is often a nuisance, as a cartridge is no longer possible despite the remaining half filling due to the hardening of the cartridge material in the upper third of the cartridge 1.
  • tubular bag can be removed after it has been opened and tied off using wire or something similar and thus sealed tightly again.
  • the tubular bag sealed in this way can then be stored for significantly longer than would be possible with an opened standard cartridge and is therefore reusable.
  • the nozzle attachment can be cleaned with a paper towel or similar can be easily cleaned and is therefore reusable.
  • the end customer can save money with the combination cartridge because they can store and reuse partial cartridges for longer and save a large amount of waste that would have been generated if standard cartridges were used.
  • Standard cartridges have the major disadvantage that they dry out on the headboard after being opened and this plug cannot be removed without destroying the cartridge. Even if there is still usable material in the cartridges after a long period of storage, it cannot be processed and the cartridge must be completely disposed of as residual waste.
