Definitions

  • the present invention relates to a recyclable tube, in particular a packaging tube made of predominantly recyclable material according to the preamble of claim 1.
  • Packaging tubes are known from the prior art, in which a tube body or tube jacket made of a laminate formed into a tube with several laminate layers made of different plastics or made of several co-extruded plastics is known and widely used. These packaging tubes are often not or only partially suitable for recycling due to the different materials that are firmly and inseparably connected to one another or to one another.
  • Packaging tubes with a tube jacket or tube body which consists mainly of aluminum are also known from the prior art. Such tubes are regularly coated on the inside of the tube body with plastics and/or paints. This means that the recyclability of such tubes is only slightly limited, but recycling does require a lot of energy. Furthermore, metal or aluminum tubes are not suitable for all areas of application for packaging tubes, for example because they are insufficiently printable or their inelasticity is undesirable.
  • the EP 3 730 420 B1 also relates to a packaging tube with an outer tube and an inner tube. However, the reuse or recycling of the tube is not discussed.
  • the object of the present invention is to propose a packaging tube which overcomes the disadvantages in the prior art and, in particular, can be fed to a high degree into a recycling process or reuse process after intended use.
  • the packaging tube according to the invention comprises a receptacle for the immediate storage of a substance to be packaged or stored. Furthermore, the packaging tube according to the invention comprises at least one shaped body to provide mechanical, static and/or dynamic stability of the tube. According to the invention it is provided that the shaped body consists of one recyclable material and the receptacle consists of a material that is adapted to the material to be packaged, with at least one separable connection being formed between the shaped body and the receptacle or a component of the packaging tube connected to the receptacle, which is designed in such a way that the connection remains valid when the tube is used as intended and that, in particular after use or before disposal, a manual and/or tool-free irreversible separation between the molded body and the receptacle at the separable connection or through the separation of the separable connection, in particular through the formation of cracks, is possible .
  • the separable connection therefore represents a type of predetermined separation connection.
  • This separable connection is designed in such a way that normal actions of using the tube have no influence on the existence of the connection produced, with an intentional and / or targeted application of force on the separable connection, preferably manually and/or without tools, can cause a disconnection.
  • the packaging tube according to the invention is accordingly based on the basic idea that the connection between fundamentally different materials or groups of materials, namely the shaped body made of a recyclable material on the one hand and the receptacle and/or the other components of the packaging tube connected to the receptacle on the other side, Regardless of whether this connection is continuous or over the entire surface or only runs along a connecting line or only includes individual connection points, it is designed in such a way that the intended use of the tube does not lead to a loosening of the separable connection and equally a provoked and accordingly preferably not typical use or Use-specific handling of the tube means that the separation of different material groups, namely the at least one molded body on the one hand and the receptacle on the other, can be achieved manually and / or without tools, so that at least one material group is separated and introduced into known and widespread recycling cycles and reused accordingly and/or can be spread.
  • the separable connection is formed along a predetermined separation contour that runs essentially around a longitudinal central axis in the circumferential direction. Furthermore, the separable connection is advantageously realized in the form of a strip or a line. On the one hand, this creates a uniform fastening and connection over the circumference, while at the same time making irreversible separation easier.
  • This separable connection is not limited to a single line or strip. Depending on the shape and intended use of the packaging tube, several lines or strips, which are preferably not connected to one another or merge into one another, can form the entire separable connection.
  • the most advantageous effect of this is that, even if the materials involved in the separable connection are not completely separated or separated, there are still only small or minimal residues of the other material or the other material group or class on the partner of the sol separation -Connection remains after the irreversible separation. Furthermore, the receptacle can be made particularly thin-walled, which has a particularly resource-saving effect.
  • the tube according to the invention enables, on the one hand, a familiar and familiar operation or use by the user and at the same time integrate or return a large part of the packaging tubes into known and efficient recycling cycles after use without sacrificing function and functionality, both in terms of use and in terms of the areas of application and materials to be packaged or stored.
  • Receptacles adapted for storing the material to be packaged can be made, for example, from a thermoplastic, an elastomer, or a thermoplastic elastomer.
  • Polypropylene or polyethylene can be used as the material.
  • the materials can advantageously consist of recycled materials, in particular of reused plastics and/or of biodegradable polymers and/or bio-based plastic.
  • Multilayer structures that can be produced, for example, by lamination or coextrusion are also particularly suitable for the receptacle.
  • Such multilayer structures can particularly preferably have a barrier layer or barrier layer. Such barriers and their implementation or formation in a multilayer composite are well known from the prior art.
  • Such a barrier layer or layer can also be created by coating and/or vapor deposition of a single-layer or multi-layer material with metallic or ceramic layers.
  • the metallic layers are preferably based on aluminum.
  • the ceramic layers are based, for example, on a silicon oxide compound.
  • the material of the receptacle is advantageously selected or influenced so that the receptacle itself or at least one surface is designed to be waterproof. If necessary, this can also be achieved by a coating on the surface(s) of the receptacle.
  • the wall thickness or material thickness of the receptacle can advantageously be less than 0.1mm, particularly advantageously less than 0.05mm, in particular less than 0.035mm.
  • the materials for forming the receptacle are particularly advantageously stretched in order, on the one hand, to make particularly thin walls possible and, on the other hand, to give the receptacle increased stability.
  • the at least one shaped body which in the tube state, i.e. in particular before the irreversible separation of the separable connection, preferably at least partially encloses the receptacle, gives the packaging the mechanical static and / or dynamic stability, which is to be understood as meaning that both during the actual handling of the tube , i.e. in particular when pressing out the packaged or stored material, but also apart from active use, namely during storage, the at least one shaped body essentially influences and / or provides the mechanical stability of the tube.
  • the separation or separability from the receptacle advantageously ensures that the shape, cross section and others
  • Design features of the molded body can be chosen and designed much more freely than with other known tubes. This not only creates advantages from a visual and aesthetic point of view.
  • Technical aspects can also be advantageously influenced by this design freedom.
  • the free choice of the shape of the shaped body enables, for example, a greater packing density of unfilled or filled tubes, which in turn leads to better use of the transport volume when shipping and transporting them.
  • the design freedom with regard to the molded bodies can also be used advantageously in terms of use and many other aspects.
  • the at least one shaped body can result in a pleasant grip or feel.
  • the recyclable material of the at least one shaped body can contain fibers or have fiber-containing components; particularly advantageously, the at least one shaped body can contain paper, cardboard, cardboard, wood fibers, cotton fibers, papier-mâché and comparable materials, such as pulp compression molding materials (“pulp compression molded -Materials").
  • the material of the at least one shaped body can also comprise metal or metal foils.
  • the at least one molded part is designed to be plastically and/or elastically deformable. The deformability can result from both the material itself and the type of processing, in particular forming of the material to produce or form the shaped body. The deformability can also be created indirectly or directly by the way in which the connection is formed with the other tube components, in particular the separable connection.
  • the at least one molded part can be designed to be waterproof or at least splash-proof. This can be done with a part of the surface or the entire surface of the molded part has an impregnation or a thin coating. These impregnations or coatings are advantageously designed in such a way that their presence does not impair the recyclability of the molded part. Accordingly, impregnations or coatings with latex or waxes, which can be removed or reused in an appropriate recycling process, come into question.
  • the molded part consists of a multi-layer material or has sections made of multi-layer material. This means that the properties of the molded part can be better adapted to use and environmental influences. Multi-layer molded parts can preferably also be created by winding individual layers that are not connected to one another or only connected to one another along one side or edge.
  • the at least one molded part is biodegradable as a whole.
  • the entire molded part, including the coating or impregnation can be degraded with high sustainability and returned to the raw material cycle, especially if the starting materials come from renewable or renewable resources.
  • the at least one molded part is printed on a surface, preferably an outer surface, or that a label is attached, in particular glued, to said surface.
  • a label is attached, in particular glued, to said surface.
  • labels they can be connected to the molded part in such a way that they can be detached from the molded part as easily and as completely or over the entire surface as possible in order to enable the molded part to be recycled according to type.
  • the receptacle is not printed or otherwise provided or mixed with paint or pigments, so that the receptacle particularly preferably remains free of dyes, varnishes or pigments.
  • the shaped body has perforations in the area of the separable connection, preferably for forming tear strips.
  • This can particularly advantageously enable an irreversible separation between the at least one shaped body and the receptacle.
  • the embodiment is particularly desirable because the user is accustomed to such perforations and/or tear strips from different areas or different types of packaging.
  • such perforations have the advantage that without corresponding tearing movements and the corresponding forces and impulses, the connection is very stable and, especially in normal use of the packaging tube, i.e. for removing the packaged or stored material in portions or completely, there is little or no fatigue or wear experienced, so that an almost unrestricted, intended use of the tube is possible.
  • a first shaped body forms an outer shell of a tube jacket.
  • This configuration is particularly advantageous because the tube jacket makes up a large part of the area of the packaging tube and a significant part of the weight or volume of the packaging tube. If this corresponding part or proportion is largely realized by a recyclable molded body, the design according to the invention of the separable connection to the receptacle or associated components of the packaging tube means that a correspondingly large part or proportion of the entire packaging tube can be separated after intended use and transferred to a recycling cycle become.
  • the shaped body as the outer shell of the tube casing can enclose and/or limit the receptacle or a part of the receptacle on the inside.
  • the outer shell of the tube casing can be formed by forming a flat or flat material, for example in the form of a thin plate or a sheet of a recyclable material. It can advantageously be provided that the outer shell is closed or completed as a whole. This means that the receptacle is not visible or recognizable in the area of the tube jacket before the separable connection is separated.
  • advantageous embodiments are also possible in which the outer shell or the tube jacket is only closed in certain areas or sections and is unlocked or open in other areas or sections.
  • this can enable simple and effective production, in particular forming, of the molded body and at the same time achieve corresponding advantages in use, for example by providing a view of the interior in non-closed or opened sections or areas arranged receptacle is made possible, so that the non-closed areas can serve, for example, as a viewing window in order to recognize or record the fill level of the receptacle and thus the packaging tube.
  • a simplified separation of the separable connection after the tube has been emptied can also be achieved by using open areas or sections as points of attack or engagement in order to irreversibly release the separable connection.
  • the separable connection is formed between a tube head and the molded body forming the tube jacket, the receptacle being connected, in particular welded, to the tube head.
  • This configuration enables, for example, the use of plastic tube heads, which are widely used and very well known in the prior art.
  • a particular advantage of using plastic tube heads is that when they are used, known and existing production machines are used both for the production and at least partially for the further processing of the tube heads, so that the total proportion of the packaging tube may be can be fed into a recycling process after use, decreases somewhat, but existing manufacturing and processing techniques and systems can be used, so that, especially for the tube manufacturer, the additional or further effort required to produce a largely recyclable packaging tube decreases accordingly.
  • a tube head in particular a tube head made of plastic
  • the receptacle especially if it is also made of plastic, for example co-extruded plastic or from multi-layer laminate
  • a wide range of experience and known processes and machines are used because in this case, apart from potentially degradable plastics or plastics of biological origin, the essential difference between the connection of a tube head with a tube jacket or Tube tube is that the receptacle according to the invention is significantly thinner or has a significantly thinner wall thickness than classic tube tubes or tube jackets.
  • a packaging tube can be realized in a particularly advantageous manner by forming the separable connection with a molded body, which preferably forms or provides the outer shell of the tube jacket, which is recyclable to a considerable extent, if not to a large extent, since after use irreversible separation of the separable connection takes place and at least one shaped body can be recycled.
  • a second separable connection is formed between the receptacle and the tube head.
  • This can particularly advantageously result in even more pure separation and improved recyclability of the tube, especially if the tube head or the receptacle alone or by itself is made of a recyclable plastic, in particular a monomaterial.
  • a shaped body forms at least part of a tube head, preferably a shoulder of a tube head.
  • a first shaped body, preferably for forming an outer shell of a tube casing, and the second shaped body can preferably be made from identical or different materials.
  • the shaped body, which forms part of the tube head can be made from a correspondingly hard material, for example hard cardboard, whereas the shaped body for forming the outer shell of the tube casing can be made from relatively deformable or less hard materials, for example paper or cardboard.
  • both molded parts are made from the same material or at least from materials that are compatible for recycling, this results in both potentially very effective production and relatively few problems in connecting the molded parts to one another or to one another.
  • uniform, in particular joint recycling can be carried out.
  • the molded parts are made from different materials, the production and connection may be more demanding or complex, but the packaging tube can then be better adapted and improved with regard to the mechanical properties and requirements.
  • the separable connection is formed between a tube head and the receptacle, the receptacle being connected to the tube head, in particular being welded.
  • part of the tube head preferably even the entirety of it Tube head, consist of a recyclable molded body, so that after the separable connection has been separated, the tube head and the molded body forming the outer shell of the tube jacket are recycled, whereas the receptacle is disposed of separately.
  • the receptacle can of course also be recycled if it is made of appropriately recyclable material.
  • the tube head consists partly of a molded body made of recyclable material, it can advantageously be provided that a part of the molded body is designed in such a way that a closure or a closure mechanism can be attached to it.
  • the shaped body can be provided with an external thread for a screw cap with an internal thread or alternatively can be provided with a snap ring to which a push-on cap with a flip-top lid can be attached.
  • the receptacle itself forms a part of the tube head, in particular a part of a closure mechanism of the tube head.
  • a tube head can be realized which is formed partly from a molded body and partly from the receptacle, so that after the corresponding separation of the separable connection, the tube head is divided into two and the two parts of the tube head can be disposed of separately and, if necessary, recycled.
  • the receptacle has an outlet section in the area of an outlet opening that is monolithically connected to the remaining receptacle.
  • This monolithically connected outlet section can be particularly advantageous by compacting and/or heating the material of the receptacle, optionally supported by a Shaping process.
  • an overall tubular receptacle undergoes compression in an outlet section with a correspondingly reduced diameter, which is then formed or formed in a shaping process into an outlet section of the receptacle, which is then formed monolithically with the remaining receptacle, but at the same time has correspondingly greater wall thickness and stability, so that said outlet section of the receptacle is well suited to forming or at least co-forming parts of a tube head and/or parts of a closure mechanism of a tube head.
  • the outlet section of the receptacle can also be led out of the interior of the outlet hole and arranged to be turned inside out or over a part of the tube head; particularly preferably, the outlet section can be turned inside out on the outside up to a shoulder of the tube head. This can ensure that the tube contents only come into contact with the inside of the receptacle and, if necessary, a lid until they leave the tube.
  • the receptacle extends at one end into an outlet hole of a tube head or beyond.
  • the receptacle can be filled with the material to be stored both from the back and through an outlet hole. It can therefore be provided that the receptacle is initially designed to be open at the back and has a closure, in particular a closure seam, which closes the initially open end after filling. Conversely, when filling through a later outlet hole, the Receptacle can also be designed as a, preferably seamless, bladder.
  • a closure of the packaging tube can be attached to or connected to a tube head in a conventional manner, regardless of this, or the tube head can be designed as a shaped body or part of a shaped body. It is possible, for example, for a tube head that has a shaped body or is formed from a shaped body to have an external thread for screwing on a screw cap. Alternatively, the tube head can have a snap ring, even if it is partially or completely formed by a molded body, in order to be able to accommodate and/or attach a pressure closure (“push-on cap”).
  • the Figs. 1a and 1b show two perspective views of a tube 02 according to the invention.
  • a closure 15 is formed on the tube body 01, which closes an outlet hole, which is not shown for reasons of clarity.
  • the tube body 01 includes an outer shell 19 of a tube jacket 05.
  • the Tube casing 05 is formed from a molded body 20 and partially encloses a receptacle 09.
  • the outer shell 19 of the tube casing 05 has uncovered sections 21, which accordingly generate spaced-apart edges 13 of the tube casing 05, between which the receptacle 09 is freely accessible or visible.
  • the tube jacket 05 is closed in the area of the tube end 07 and has a kink 08 there, so that both sides 05.1, 05.2 of the tube jacket 05 can be made from a common, preferably from a flat or arcuate material, as with reference to Fig. 2 will be described in more detail.
  • the shaped body can also have several parts, preferably made of the same material, which are connected to one another or to one another, at least in sections. So instead of the kink 08, a connection, for example an adhesive connection, could also be provided, which then connects two individual parts in the form of the two sides 05.1 and 05.2 to form the molded part 20 and / or the tube jacket 05 in sections.

  • the separable connection 22 can preferably be designed as a line connection that extends over the entire circumference and particularly preferably only to a small fraction of the length of the tube 06.

Also in the embodiment of Fig. 3 It can be provided that a separable connection 22 running over the circumference is formed at a transition (not shown) between the molded part 20 and a tube head 06. In this case, after the tube 02 according to the invention has been used as intended, the first shaped body 20 can be separated from the rest of the packaging tube 02 along the separable connection 22.

It can also preferably be provided that a total of two separable connections 22, 22.1 are formed, on the one hand between the shaped body 20 and the tube head 06.1 and the receptacle 09 and on the other hand between the receptacle 09 and the tube head 06.1.
  • a separation of the shaped body 20 from the tube head 06.1 and the receptacle 09 and a further separation of the tube head 06.1 from the receptacle 09 could be achieved by appropriate force, in particular by appropriate manual and tool-free force on the separable connections 22, 22.1, so that tube head 06.1 , receptacle 09 and shaped body 20 can each be disposed of separately and, at best, recycled.
  • FIG. 5 Another embodiment is shown in the Fig. 5 sketched. This merely serves as a schematic illustration of a principle. Because the tube or tube head 06.1 shown shows very schematically a receptacle 09 compressed in the area of the outlet hole 04 and in the area of the outlet section 29, the compression of the receptacle 09 being achieved, for example, by reducing a diameter of the receptacle 09 in the outlet section 29 and in the area of the outlet hole 04 is caused. In the embodiment of Fig. 5 It can advantageously be provided that the receptacle is guided up to the outlet hole 04 and/or forms this. In contrast to other embodiments according to the invention, such as in Fig. 4a, 4b , this prevents the substance to be stored from coming into contact with the tube head.
  • the receptacle 09 is not only arranged loosely in the compressed state, as shown in the schematic diagram Fig. 5 could be suggested, but rather that the compression is accompanied by a deformation and/or thermal exposure, so that a section of the receptacle 09 is formed as a compacted and/or monolithic continuation, which has a correspondingly greater wall thickness and thereby either forms parts of the tube head 06.1 or only other parts of the tube head 06.1 are reinforced, for example in mechanical terms.
  • the compaction of the material of the receptacle in the area of the outlet section 29 can be done, for example, with a heated male die.
  • the separable connection 22 can be formed at different locations or in different areas, for example the separable connection 22 can be in the area of Be formed outlet hole 04. But it is also fundamentally possible to form the separable connection 22 in the lower section of the outlet section 04 or even in the area of the shoulder 03, possibly even in the area of the tube jacket 05.
  • the receptacle 09 is led out of the outlet hole 04, folded over or turned inside out over the outlet section 29 and guided backwards in the outer area or on the outer surface of the head and/or the tube.
  • a separable connection can then be formed on the outer surface of the head 06.1 or the shaped body 20.
  • the receptacle 09 can preferably merge into itself or form a self-connected double-walled tube, in the interior of which the shaped body 20 and/or the tube head 06.1 is then enclosed.
  • the receptacle can serve as a coating outside.
  • the receptacle 09 can also be separated from the at least one shaped body in the outside area of the tube by a separable connection without leaving any significant residue.
  • the Fig. 6 shows a cross section through a further embodiment of a tube according to the invention along a longitudinal axis. This also differs from the embodiments with regard to the shaped body 20 1a to 3 .
  • the Fig. 6 shows that the receptacle 09 is enclosed by a molded body 20 formed by rolling up a strip of recyclable material, which provides the tube jacket 05 or the outer shell of the tube jacket 05 of the tube.
  • a wound design of the shaped body 20 to provide an outer shell of a tube jacket can, for example, enable an advantageous attachment in which the tube head 06.1 and the receptacle already attached to it rotates about a longitudinal axis become.
  • the winding can have one or more layers. If there are several layers, these can advantageously be unconnected to one another or only connected to one another on one long side.
  • the Fig. 7 shows an embodiment of the packaging tube according to the invention, in which the shoulder 03 is flat.
  • the shoulder 03 and the jacket 05 can, for example, be formed from one or two separate molded parts 20.
  • the remaining tube head 06.1 includes a thread 31 for attaching a closure.
  • This outlet section 29 of the tube can, for example, be formed overall by a compressing and/or reshaped section of a receptacle 09, which is then guided through a corresponding opening in the second molded part 30 or in the common molded part 20 to form the shoulder 03 and jacket 05.
  • a separable connection 22 can be formed in the area of the shoulder 03.
  • the separable connection 22 can also be formed in the area of the tube jacket 05.
  • the opening or the edge of the opening could also be used to form the separable connection 22.
  • the Fig. 8 shows an example of a label with disposal instructions that can be attached to the tube according to the invention.
  • the tube jacket 05 can also be printed with such a note.
  • the receptacle 09 is designed to be free of dyes or pigments in order to also enable or improve the reuse or recycling of the receptacle 09.
