Abstract

Two congruent surface portions (28) of a flexible laminated material, of which at least one main surface is provided with a heat-sealable and sealingly closing lamination, are laid one on top of the other in such a way that the laminated surfaces lie one on the other. Under the effect of heat, sealingly closing edge zones (34) are formed on these surface portions on the lower parts of the container. These zones delimit a filling space (31) with the exception of a filling orifice (30). The container lower parts which are formed in this way and which can be stacked in a sheet-like manner are deformed by widening means in such a way that the filling space is brought to the desired volume from the cut-out filling orifice. The filling space is thereupon provided with filling material and the filling orifice is subsequently closed by means of a headpiece (33) which can be welded in and which contains an outlet connection for extracting the filling material. <IMAGE>

Description

Tube-like container and method of filling and closing. Her-

present a tube-like container The invention relates to a Tube-like container for liquid or paste-like filling goods or the like with a consisting of flexible material, the filling space of the container forming the container base and with one with the upper, preferably frontal end of the container lower part tightly flowing head part with a product dispensing and closing device, which are preferably designed as an outlet connection with an external thread for screwing on a cap is trained. The invention also relates to a method for filling such a Tube and a method of making such a tube.

Such containers, in particular tubes, are known and are in As a rule, from the tube manufacturer, preferably in a waste-ready form Bottling plant or generally supplied to the tube consumer. This then fills the tube with dome to be packaged and closes it after completion of the filling process, This approach involves a number of difficulties and disadvantages can have adverse effects to varying degrees depending on the case. Exemplary the following should be noted: a) The volume from the tube manufacturer to the tube consumer to be transported empty tubes is practically the same size as the volume of the filled tubes. The same applies to the storage of empty tubes. In principle, will completely uneconomical filling volume transported and stored. It must be precautionary be taken so that the empty tubes are not inadvertently deformed, which is the case Insertion in filling equipment can lead to difficulties.

b) It can hardly be ruled out that most of them are in the delivery condition open tubes at least in the opening area during transport or as a result of manipulation through dust or the like.

to be polluted. This requires that it be sterile before filling holding goods certain parts of the tubes in cleaning and sterilizing facilities need to be treated.

c) The printing of tube preforms after their manufacture is Expensive because the work processes required for this can only be insufficiently automated and must therefore be carried out on relatively slow running machines.

d) The area available for printing is through the Tube size fixed and usually insufficient for small tubes. Often enough but even with larger tubes the available space does not run out of space to use the necessary text to be appropriately attached to the tube surface so that the a separate leaflet must be enclosed with filled tubes. This can be easy get lost if not z. B. comes with additional packaging for the tube will.

e) The type of tube production customary today leaves little room for maneuver in terms of design. There are only possible variations in the area of the tube closure or

of the upper part of the tube. The tube skirt itself can usually only be cylindrical or be slightly conical. For this reason it is often tried through an additional Cardboard packaging to create differentiators.

The object of the invention is thus to create a container in the manner of a tube for liquid or paste-like filling goods, in which the above mentioned disadvantages do not exist.

In particular, a container of the type mentioned is to be created which is only a fraction of the Volume of the filled container owns. If imprints are necessary or are desired, these should be able to be applied using the planographic printing process and if possible be visible throughout the life of the container. And finally supposed to a container in the manner of a tube can be created by varying the shape of the container to meet both purely practical and aesthetic wishes.

To solve this problem, the invention proposes a container of type mentioned above, which is mainly characterized in that the Lower part of the container made up of two lying one on top of the other and running along one circumferential The edge area is composed of flat parts that are tightly connected to one another is, wherein said edge area is the filling space with the exception of a section limited at the upper end, preferably the end face, of the container base, and that the lower part of the container in the region of said section at its upper End with the peripheral surface or the like. Of the head part is connected. Such a tube-like one The container has the advantage of initially being sent separately in the lower part and the head part to be able to, with the layers forming the lower part flat on top of each other can lie. After the one adapted to these circumstances and in the following even closer explained filling of the lower part, the head part z. B. fixed in the AbfUllbetrieb will.

It is particularly useful and advantageous if the head part a substantially axially oriented edge flange with an inner one, the outlet port Od. Like. Opposite support surface and with a substantially parallel to Behäl ter-longitudinal axis-oriented circumferential surface has. Such a headboard leaves well into the lower part of the container, which has been appropriately expanded beforehand insert, after which then between the edge flange of the head part and in particular the inside of the upper end of the container base made a tight connection can be. This arrangement makes it possible to initially remove the container base from the Front side closed and then insert the headboard. Of the The lower part of the container can therefore already be closed at its edges up to the front side which simplifies shipping as the lower parts all lie flat on top of each other can. It is only necessary to spread or unfold the front side for filling, after which the closure can then be attached to the head part immediately.

At least the side facing the filling space of the container can thereby the flat parts forming the lower part of the container or the like.

have a sealable thermoplastic surface. Then can The lower part of the tube and the head part are connected to one another by heat sealing.

A particularly advantageous and expedient embodiment of the invention can consist in that the flat parts forming the lower container part consist of a layer material which consists of at least one carrier material layer and consists of a sealable thermoplastic cover layer.

It is particularly useful if the parts forming the lower part of the container flat parts at least partially consist of cardboard. This is the manufacture and in particular printing is also particularly favored. First of all, cardboard is a inexpensive material and the loss of material when throwing away the squeezed tube is correspondingly low.

The head part can be made of one with the thermoplastic surface of the The lower part of the container is made of weldable or bondable plastic material. If the lower part of the container is glued to the head part, can be on an inner layer the lower part of the container made of thermoplastic material is optionally omitted will.

The simplest embodiment of the container base can through formed two blanks placed one on top of the other and connected to one another in the edge area be. Another possibility However, there is * that the Container base forming first material od a tubular layer material. like

which consists of at least one carrier material layer, and that one end of the lower part of the container by flattening the hose material and Welding of the thermoplastic surface layer delimiting the filling space is tightly closed. The aforementioned welding of two flat blanks However, in the edge area it has the advantage of being simpler and faster Manufacture and the ability to ship the lower part of the tube in a flat position. In addition, a wide variety of Vmrißformen can be provided.

The edge areas can also be of different widths and, for example equal to printing instructions for use or for advertising imprints or the like Are available so that additional boxes with inserted instructions for use or the like can be avoided. Also, such can be widened and glued together Edge areas next to the actual container area as suspension or for recording or the like.

It is particularly advantageous in particular for the connection between the head part and the lower part of the container, if between the preferably of inside outwardly tapering outlet connection of the head part and its partially inwardly drawn-in circumferential surface a channel-shaped circumferential groove or the like. Depression is provided, the cross section of which is in the plane of the edge region of the The lower part is larger than in the case of a somewhat flat tube, in particular which is approximately at right angles to the plane. In this way a sealing device can then Only attack the face of such a tube and apply pressure and counter pressure do not have to be partially applied from the inside of the tube. Accordingly is the sealing of the head part with the container base after filling the Tube easily possible. In the previously known tubes, the filling takes place in usually after inserting the headboard from the lower opposite end the tube, which end is then still closed will. It is now part of the present invention, a simplified one and the possibility of transport the tube lower parts in a flat position aligned method for filling a to create such a tube-like container.

This method exists according to the invention - as already indicated above - In that first the lower part is filled from the front and then his Front side is closed with the head part. They can initially be flat on top of each other lying tube walls by upsetting or the like. Two opposite one another Edges in the area of the front side of the lower part are arched away from each other, then the filling can be carried out from the front and finally the Headboard can be used. The lower parts of the tube can therefore practically completely be prefabricated and do not have to be after filling on their opposite to the head part Be closed at the end.

It also belongs to the present invention, a method for To create a container of the type described above and mentioned at the outset. This method consists in that the lower part of the container is placed on top of each other before filling two flat layer materials, of which the opposite Surface parts can be welded to one another under the action of heat, and through Heating a certain portion of these layer materials to produce a an edge area delimiting the filling space is produced, the heated Surface parts are tightly connected to one another, in particular welded, and that the edge areas formed in this way, which are preferably in one plane, especially before filling are moved against each other to the initially flat Filling space to be spread apartf If a hose material is used for this purpose, there are already two edge areas connected to one another from the outset; another possibility is that for the production of the container base one of two with respect to a longitudinal axis mirror-inverted halves existing blank from the Layer material od. The like. The later tube forming material produced is that this blank with a notch or fold line lying on the longitudinal axis is provided and that the blank is folded along this line such that the preferably thermoplastic-coated sides of the Zusclmitthälften face each other. In such a case, there is an edge area already connected from the start, namely the folding point.

Finally, a preferred method may be * that two Sheets made of sheet material especially for several tube-like containers with their connectable, preferably sealable surfaces placed one on top of the other and leaving them free the filling spaces are interconnected and that preferably immediately after connecting the individual sub-parts by punching completely or partially from one another be separated.

Especially when combining one or more of the above Process and process steps ultimately result in a process for production a tube provided with filling material in the following way: a) production of a container head part, b) Manufacture of the lower part of the container by placing two on top of each other Layers of material, of which the opposing surface parts can be welded to one another in particular by the action of heat, and heating a certain section of these layer materials to create the filling space delimiting edge area, the heated surface areas close together be welded, c) expanding the filling space to form an opening edge part on the front side of the lower part of the container and filling in the filling material in the lower part of the container, d) placing the head part on the opening edge part of the Lower container part and inserting the edge flange on the head part into the opening edge area of the container base and finally e) making an air or liquid-tight connection between the edge flange on the head part and the Opening edge of the container base. In this case, those concerned with the production Steps a) and b) may also be carried out in a manufacturing plant, while steps c) to e) can be carried out later in the bottling plant. Overall, this results in a tube that is simple and inexpensive to manufacture and is easy to handle and when thrown away after emptying there is no major loss of material means. Nevertheless, the advantages are particularly important when transporting the still unfilled Tube parts considerably, since the lower parts of the container can be flat and so little space take away. In addition, there is no risk of crushing the lower part of the container, so that this may later no longer fit into the filling device.

Finally, loading a filling station is also easier, since on the one hand more container parts fit into a corresponding magazine, so that the magazine does not have to be refilled as often, and on the other hand again the supply from the magazine to the actual filling station can be made more problem-free can.

Further features and refinements of the invention are essential Significance are the subject of further claims.

The following is the invention and its essential pertaining to it Details are described in more detail with reference to the drawing. It shows in partly schematic Representation: Fig. 1 a shows a container designed according to the invention in the form of a Tube in a longitudinal section transversely to the connecting plane of the two the container base forming layer materials, Fig. 1b a longitudinal section through a tube-like Container through the connection level and through the edge area of the lower part forming layer materials, Fig. 2 shows a head piece with at the top Edge of its edge flange attached, again running downward clamping flange to include the upper edge of the lower part it, Fig. 3 is a head piece without additional Clamping flange before being placed on the lower part of the container, FIG. 4 schematically shows the successive steps for the production of individual sub-parts into containers or tubes according to FIG. 1 made of layers which can be folded around a central fold line, 5 schematically shows the successive steps for filling and sealing from from container lower parts resp.

Tube bodies according to FIG. 4 and head pieces according to FIG. 3 existing Containers or tubes, FIG. 6 schematically shows the printing of items supplied on rolls Web material for the manufacture of the lower parts of the container or

Tube body, Fig. 7 schematically shows the successive steps for the production of finished containers from unfolded, delivered on a roll, optionally printed web material, Fig. 8 schematically the successive Steps for making sheet container base material wound on rolls of unfolded and unprinted continuous web material, Fig. 9, 10, 11, 12 and 13 examples of containers or tubes produced according to the invention Method, FIGS. 14 a to d schematically show the successive manufacturing steps from Tube bases from the blanks to be laid on top of one another, each of which has several filling spaces at the same time and are cut apart after joining, Fig. 15 shows a longitudinal section corresponding to FIG. 1 a through one of two initially separated Tube according to the invention formed from blanks, FIG. 16 shows a longitudinal section accordingly the illustration of FIG. 1 b through the tube shown in FIG. 15 and FIG. 17 a plan view of the tube according to FIG. 16 and in particular of its head piece.

In the case of the one in Fig. 1 a, b in two perpendicular longitudinal sections The tube shown denotes 1 the lower part of the tube or tube body, and 2 the upper part of the tube or tube head, which are inextricably connected to one another along a connecting area 3 are. As explained in detail with reference to FIG. 4, the tube body 1 consists of a Laminate structure in which, for example, two opposing plastic-laminated Cardboard blanks to form a pocket, which in the assembled state of the tube defines a filling space 4, and over a tightly closing edge area 5 with one another are firmly connected. The tube head 2 can be a plastic or metal part, which is manufactured separately and in a known manner an outlet and closure section 6 and a shoulder section 7 contains. There is a connection flange on its periphery 8 integrally formed, on the outside of which is preferably parallel to the longitudinal axis of the tube extending connecting area 3 between tube head 2 and tube body 1 lies. Of the Bonding area 3 is expediently created by heat sealing, with the plastic lamination of the laminate structure is welded to the outer surface of the connection flange 8 will.

Variants of the tube shown in Fig. 1 are from the Partial representations in Figures 2 and 3 can be seen.

Using the tube body 9, which is a fully printed flat or web material can be withdrawn from supply rolls are from the ones shown Components 9, 10 or 9, 17 constructed tubes according to the invention can be produced. Of the Tube head 10 according to FIG. 2 has an outlet and closure section 11 and a Shoulder part 12 as shown with reference to FIG. 1. Closes to the shoulder area 12 in this case an inverted U-shaped clamping flange 13 radially outwards.

After creating a transverse seal on the lower (not shown) End of the tube body, the spreading open of the filling opening or rounding the upper one Edge 14 of the tube body 9 and filling the same becomes the edge 14 of the tube body 9 inserted in the direction of arrow A into the opening 15 of the clamping flange 13. By pressing the outer leg 16 radially inward on the clamping flange 13, the tubular tube body 9 is firmly connected to the tube head 10. The resulting Connection can also be glued or welded by the action of heat. It is through the circumferential annular groove between the shoulder 12 and the flange area the pressure and counter-pressure forces can be applied outside the tube itself.

The tube head 17 according to FIG. 3 can be the same as that shown in FIG be designed and have a substantially axially parallel connecting area 18. In this the tube body 9 after transverse sealing of its lower (not shown) At the end, the spreading of the filling opening or rounding of the upper edge 19, filling of the tube body 9 and pushing its rim of the 19 onto the connecting flange 20 connected to the tube head 17.

The tubes produced according to FIGS. 1, 2 and 3 thus exist from two separate to the tube consumer or tube filler to be delivered separately Parts 4, namely: 1. the tube head 2, 10, 17, which is preferably complete with a mounted, not shown tube closure is provided, and 2. the tube body 1, 9, in the form of a flat blank (Fig. 1), or one flattened tubular sheet material, both the blank and the tubular web material with all the desired, which can be created using the flat printing process Imprint is provided.

As will be explained later, the cut can be largely arbitrary be designed. It goes without saying that the blank material also, as based on the Fig. 6, 7 and 8 shown, pretreated as sheet material and continuously attached to tube filling and closing devices can be delivered. Tubular sheet material can for example be printed in the manner described with reference to FIG. 6 and for pre-assembled for use on a tube manufacturing machine (not shown) will. Production that is practically possible without operator intervention and handling of the tube body material allows largely sterile processing the same including the filling area, so that often only in extreme cases additional cleaning or sterilization of the filling area or the filling area becomes necessary on the tube body. Likewise, the tube heads can practically without Interventions made by operating personnel, provided with locking elements and are delivered to the tube filling and closing stations, so that even with the Tube heads can usually be dispensed with additional sterilization processes.

Fig. 4 shows one way of producing a tube body of Type used in Fig. 1: Blanks 21 made of a layer material on the one side with an airtight and liquid-tight sealable thermoplastic Plastic is covered and the carrier material is cardboard and metal-coated paper Od. The like. Are in their length center with a fold or score line 22 provided. The size and shape of the blank 21 is preferably selected so that that subsequent reworking, in particular cutting operations, is omitted if possible can. In a further work step, the blank is drawn along the fold line 23 so folded (arrow B) that the sheet side provided with the thermoplastic layer 23 after comes to lie on the inside and the leaf halves lie congruently on top of each other come.

The folded pieces 24 formed in this way then become one (not shown) heat sealing point fed into which the two superimposed Leaf halves in area 23 of the right-hand partial illustration in FIG. 4 Heating the thermoplastic layer mentioned, welded to one another tightly will. A filling area 26 from the opening side remains unwelded 27 is accessible. Unless already the blanks 21 with an imprint are provided, imprints can practically in all other of those shown in FIG Manufacturing stages are attached. In cases where a highly sterile filling area is desired is, the pressure is appropriate either before the blank is coated 21 or after completion of the welding process in the last stage according to FIG. 4.

In FIG. 5, the manufacturing steps of a filled tube are those according to the invention Kind shown. At the left end of the figure there is a stack 28 of tube bodies, such as they are present from the last stage of FIG. From this pile are individual Tube body 29 is lifted and then the filling opening of the filling space is easy pre-expanded, as indicated by 30. The filling room is in a subsequent station 31 widened so much that the intended amount of filling material can comfortably be accommodated in it finds. The filling station or the filling process is designated by 32. The following Operation consists in bringing a tube head 33 up and putting it on on the filled tube body 34. Finally, the connecting flange of the in Fig. 1, 3 detailed tube head welded to the upper end of the tube body * as in the last stage of the in Fig. 5 by the arrows in the upper end of the Tubenkdrpers 34 and on the edge of the tube head 33 are shown.

FIG. 6 shows one possibility of printing items delivered on rolls 35 plastic-laminated web material, namely both in shape of flattened sheet-like tubing material for the production of tubes of the in the type shown in Figures 2 and 3, as well as in the form of sheet material from which Blanks 21 of the type shown in Fig. 4 can be separated. The two reels 36, 37 schematically represent a printing unit with which both one and two sides can be printed. At 38 is a supply roll with printed laminated web material denotes that depending on the chosen type of packaging for delivery to the manufacturers of tubes according to Figures 2 and 3, or the manufacturers of blanks 21 according to FIG. 4 is suitable.

Web material of the last-mentioned type can also be in an arrangement according to FIG Fig. 7 are used where printed from a supply roll 39 and with a center fold line 40 provided web material is withdrawn and initially fed to a folding station 41 will. A continuous double web material 42 is produced in this folding station, in which thermoplastic-laminated surfaces face each other. This web material then arrives at a sealing or welding station 43, in which by welding jaws 44, 45 successively contiguous tube bodies 46 of the in Fig. 5 with 28 designated type. In an expanding or opening station 47 the tube body 46 is opened by an expansion device 48 and in a subsequent one Filling station 49 filled.

A feed device 50 guides tube heads 51 to a closing station 52, in which the filled tube bodies are closed and sealed. In the end the closed tubes 53 are separated by knives 55 in a separating station 54.

In such a system, printed and (possibly) pre-creased laminated web material can be transferred into individual tubes in 6 steps.

One way of producing on a continuous belt ready to be filled available to the tube consumer or tube filler Tube bodies is shown in FIG. 8 shown. Located on a supply roll 56 unprinted and unfolded thermoplastic laminated web material z. B.

of the type described earlier, which is a printing unit 57 for attaching is fed to the tube labeling. After printing, the web material passes a scoring or folding device 58 for making a score line or a fold groove.

The web material is then folded in a folding station 59 in such a way that that the sheet material side provided with the thermoplastic lamination faces inwards come to lie. The now doubled sheet material then arrives in a continuous ch working heat sealing station 60, in which the lamination with the exception of the Füliraumstellen 61 is welded. The web material leaving station 60 with tube body moldings continuously arranged thereon, then on wound up a second supply roll 62, which is supplied by the tube body maker is delivered to the tube consumer or tube filler. This then still needs a system which in principle corresponds to that section of the arrangement shown in FIG. 7, which is an expanding or opening station 47, a filling station 49, a feed device 50 for tube heads 51, a closing station 52 and a separating station 54 contains to To be able to manufacture filled individual tubes ready for dispatch.

While with reference to Figures 1, 4, 5, 6, 7 and 8, the production of Tubes or tube bodies are shown in which the one that delimits the filling space is welded Edge zone limited to what is necessary to achieve the desired seal is shown, it is understood that when using doubled sheet or Tape material, for example according to FIG. 14, tube bodies of different shapes can also be easily produced are. Examples of this emerge from FIGS. 9, 10, 11, 12 and 13. Fig. 9 shows an embodiment of the tube in the form of a card, in which in addition to the Filling space 63 a relatively wide section 64 is present, which on both sides with a Text can be printed so that the submission of a separate brochure is avoided can be. FIG. 10 shows a tube 65 with a hanging loop 66, and FIG. 11 shows a tube with a bubble-shaped filling space 67 and one hexagonal in elevation Tube body 68. This embodiment clearly shows that designed according to the invention Tubes have a relatively large scope for design needs to be offered. In Fig. 12 an application form of the inventive concept is shown, wherein several, In the exemplary embodiment, two tubes 69, 70 of the ones described, for example, with reference to FIG. 1 Art are arranged in a reed body 71 containing both tubes side by side, which also contains a receptacle 72 for accommodating a tool 73. Such arrangements are, for example, for the provision of multi-component adhesives or used by goods of different strength classes and the like. In the end 13 shows an erectable tube 74 with a rectangular tube body 75 which side a triangular inactive leaf 76, 77, z. B. along a folding or score line 78, 79 is pivotably articulated.

It goes without saying that the design examples described with reference to the drawing of the container according to the invention can still be expanded. In particular, exist regarding the choice of materials for both the tube body and the tube head in itself only restrictions that affect the compatibility with the filling material and the possibility of a permanent and tight connection.

A particularly important and advantageous manufacturing process is shown on the basis of FIG. Some of them are marked with A and B and are large Lay blanks 21 with mutually facing weldable thermoplastic layers on top of one another and to divide it up so that the total area after the welding of the corresponding areas in individual blanks after the last process stage in FIG. 2 or also in FIG. 14 can be separated. Since the large-area blanks 21 a corresponding shaped welding device easily fed and practically simultaneously by punching can be separated, such a method according to FIG. 14 can be carried out quickly and beneficial. By changing the dividing lines you can do this even Desirably, several tubes remain within an edge area in order to z. B. the embodiment according to Fig.

12 to form.

By means of separate, stackable and connectable blanks tubes 101 result according to FIGS. 15 to 17. In these FIGS. 15 to 17 shows a slightly modified head piece 102 at the same time. In this case the edge flange 8 gives way to the edge of the circumference directed into the interior of the container surface 3 obliquely radially inward and forms a conical insertion area 103, which means that the head part 102 is inserted into the front part spread open Container lower part 101 facilitates and can thus accelerate.

The outlet nozzle 11 on the head part 102 runs at least on its interior End 11 a conically from the inside to the outside, so that even when the upper, the head part 102 having area of the entire tube of the rest Contents can still be squeezed out of the tube. The relatively large end area 11 a of the outlet connection 11 then also allows compression.

The plan of the head part 102, which is also used for the other gopfteile can be used in the other embodiments is good in FIG recognizable. He is according to this embodiment at least on its outer, with the The end face of the lower part 101 terminating edge is approximately diamond-shaped. The corners 104 of the diamond-shaped cross-section are each with the larger angle rounded off. One can clearly see that the more pointed corners are in the edge areas 5 of the entire tube-like container pass over, while the flatter sides of the rounded corners 104 are formed whereby the from his the head part 102 end facing away from FIG. 15 towards the head part h-in widening cross-section of the container lower part 101 can adapt well to this head part 102. The one with it Selected and intended somewhat flat shape later favors the squeezing out and also the filling of this container beforehand.

Instead of the embodiment according to FIG. 17, it is also possible that the plan of the head part 102 at least in its the end face of the container lower part 101 corresponding edge area of two flat arcs, in particular circular arcs preferably the same length, is formed, which is at an acute angle in the edge region of the container base 101 hit.

Also in this embodiment it is provided that between the outlet port 11 of the preferably conically tapering from the inside to the outside Head part 102 and its partially inwardly drawn circumferential surface 3 a Groove-shaped circumferential groove 105 or the like. Depression is provided, the cross section of which in the plane of the edge region 5 of the lower part 101 due to the imple mentation The geometric relationships provided in this example are expediently greater than those in which is approximately at right angles to the plane. This circumferential groove 105 allows the attack of a sealing device after the tube has been filled, i.e. when a counter pressure no longer received in the edge area of the tube by a mandrel pushed into the tube can be.

It should also be mentioned that the outlet connection 11 in a known manner at least in the area of its external thread, preferably also in the area of the deeper, conical zone 11 a can have a circular cross-section.

In particular when applying the method according to FIG. 14 and using it 15, a tube-like container can be created overall and fill without taking up unnecessary space during the transport of the unfilled parts is consumed and there is a risk of damage. In addition, there is a printing simplified. At the same time, a cheaper material than the usual metal can be used are used for such tubes and compared to a plastic tube is the Advantage of easier handling, especially when emptying, since after resetting no or at least lower restoring forces than with a plastic tube are expected to suck the filling back from the area of the outlet connection could. Another relief is that at least in many cases a special one Packaging box with additional instructions for use can be saved, as the instructions for use can be applied to the edge area.

All in the description, the following claims and the drawing The features and construction details shown can be used individually or in any combination with one another are of essential importance.
