Definitions

  • the invention relates to a method according to the preamble of claim 1.
  • Known tubes with a closable outlet have a generally cylindrical aluminum container, which is provided at one end with a slightly conical end wall and an outlet nozzle. The latter has a thread and can be closed with a screw cap. When the tubes are manufactured, their end facing away from the outlet is left open. When filling the tubes, the contents are filled through the open end and closed after filling.
  • the empty tubes Since the aluminum tubes and the contents filled into them are normally manufactured in different manufacturing plants, the empty tubes have to be transported from the tube manufacturing plant to the manufacturing plant where they are filled.
  • the transport and storage of the empty, essentially cylindrical tubes therefore require large transport or storage spaces, which adversely affects the economy.
  • the empty tubes that are open at one end, it is practically impossible to prevent contaminants such as dust from getting into the empty tubes. In many cases, this makes complex cleaning and sterilization processes necessary.
  • the tubes are usually with one Another disadvantage of these tubes is that the print has to be applied to a cylindrical surface, which is relatively expensive.
  • plastic tubes are also known, the generally cylindrical tube shell of which is so elastic that it resumes its original shape after the filling material has been pressed out. This ensures that the print on a tube remains legible even when the tube is largely empty.
  • the mentioned elasticity and dimensional stability of this tube has the consequence, however, that air is sucked into the tube during the re-expansion of the tube following the pressing out of the filling material. In many cases, this is disadvantageous for the remaining filling material still contained in the tube.
  • the plastic tubes have disadvantages that are similar to those described above for the aluminum tubes.
  • tubes which have a tube body and a head part connected to it.
  • the tube body has two walls made of cardboard, which is coated on the inside with weldable plastic.
  • the two walls are connected by a folded edge at one side edge and are welded together at their two side edges and the edge facing away from the head part.
  • the head part has an outlet connector provided with an external thread, at the end of the tube body side adjoining a shoulder section consisting of a conical and a radial section.
  • a flange is formed on the periphery of the shoulder section and has a section that runs cylindrical and coaxial with the outlet connection piece from the shoulder section and from the tube interior.
  • a radially outwardly projecting collar then adjoins this.
  • the head part can be made of plastic and welded to the tube body.
  • the tube bodies and head parts are produced separately, the tube bodies remaining open at their end on the head part side and being welded at their other edges. After completion, the tube body and head parts are stored separately and transported to the tube filling station. The walls of the tube body lie flat on top of one another during storage and transport and are only spread apart from one another when the contents are filled. When a tube body is filled, a head part is then inserted into its open end and welded to the tube body.
  • the tubes known from the Swiss patent specification 610 259 have the disadvantage that the head parts, which are preferably made of weldable plastic, must extend over the entire cross section of the end of the tube body on the head part side. So that the head parts can be welded to it when the tube body is full, they must also have the flange mentioned. Since the head parts are made of a relatively expensive plastic, the production of the tubes by the head parts is considerably more expensive. This increase is particularly noticeable in the case of tube-like containers with large cross-sectional dimensions weight. Furthermore, the complicated shape of the head parts also increases the manufacturing costs.
  • the flanges of the head parts must also fit exactly into the open ends of the tube body, which also increases the manufacturing costs. Furthermore, welding the head parts to the tube bodies requires complicated and costly facilities and work operations. So that the contact pressure required for welding can be generated, the annular flange and the edge of the tube body must be pressed against one another from both sides with tool parts.
  • tubes with an essentially rectangular outline are now known, for their manufacture on a soft, planar workpiece which subsequently forms the tube body afterwards, an outlet is welded on to the end face of the tube.
  • the flat workpiece is folded before or after the outlet is welded on in such a way that the two walls of the tube are connected at the front and are separated from each other by a folding edge.
  • This fold edge, or more precisely, the sections thereof on both sides of the outlet runs along a straight line which intersects the tube axis running through the outlet.
  • the planar workpiece is welded at those edges which subsequently form the side edges and the edge of the tube body facing away from the outlet.
  • the zones are welded to one another, which are located on different sides of the outlet at the fold edge mentioned, in which the two walls are connected.
  • the two tube walls therefore lie flat against one another not only at the two side edges and the edge facing away from the outlet, but also on part of the end face.
  • the two walls are only separated from each other by the outlet just in the middle of the front. Since the walls are also made of a soft and limp material, they lie on top of each other almost everywhere when the tube is empty. Before the filling material is filled in, there is practically no free cavity between the two walls. The two walls are then pushed apart from each other by the filling material.
  • the tube therefore has no defined volume, which is disadvantageous for many applications. If the tube contains a pasty filling material with low viscosity, the filling material can also run out of the tube in a short time when the tube is lying open on a table or the like, without the tube being compressed manually.
  • the invention has now set itself the task of a Ver drive to manufacture a deformable container, which makes it possible to avoid the disadvantages of the known manufacturing methods and the disadvantages of the containers manufactured by these previously known methods.
  • the container should in particular be compressible for pressing out the filling material, but still have a certain dimensional stability, so that its walls form an open cavity even before the filling material is filled in and do not collapse on their own.
  • the invention further relates to a deformable container according to the preamble of claim 4.
  • the container is characterized by the features of claim 4.
  • the invention further relates to a flat workpiece according to the preamble of claim 9.
  • the workpiece is characterized according to the invention by the features of claim 9.
  • the tube-like, deformable container 1 shown in FIGS. 1 to 3 has a tube body 3 and an end face 5 with an outlet 7.
  • the longitudinal axis of the outlet 7 is designated 9.
  • the tube body 3 has two walls 3a, which are generally rectangular Have an outline, are located on different sides of a plane of symmetry 11 running through the longitudinal axis 9, are symmetrical with respect to this plane of symmetry 11 and are also individually symmetrical with respect to a plane of symmetry 13 which runs through the axis 9 at right angles to the plane 11.
  • the central parts of the two walls 3a are convexly curved in a cross section to the axis 9.
  • the two walls 3a each have a flat, strip-shaped edge section 3b on opposite sides of the symmetry plane 13 and a flat, strip-shaped edge section 3c at the end facing away from the outlet 7.
  • the three strip-shaped edge sections 3b, 3c are connected without interruption in each of the two walls 3a. Otherwise, the edge sections of the two walls 3a lie on top of one another in pairs and are tightly welded to one another.
  • the two walls 3a, together with a middle section 3d connecting them consist of a one-piece, first workpiece.
  • the end face 5 with the outlet 7 is formed by the mentioned middle section 3d and a second workpiece which is welded to the middle section.
  • the central section 3d essentially has the shape of a convex lens, the edge sections 3b projecting like wings on the acute-angled corners of the lens on both sides of the plane 13 .
  • the central section 3d is indented such that it approaches the peripheral section 3c from the peripheral sections 3b to its center.
  • the middle section 3d is thus connected on both sides from the plane of symmetry 11 via a folded edge 3e to one of the two walls 3a. In the areas of the edges 3b, the two folded edges 3e unite on both sides of the Plane of symmetry 13 for a single fold edge lying in plane of symmetry 11.
  • the outlet 7 is formed by the already mentioned second workpiece and has a cylindrical connection piece 7a with an external thread and a collar 7b.
  • the collar 7b bears against the surface of the middle section 3d facing the interior of the container and is tightly welded to it.
  • the diameter of the collar 7b is smaller than the smallest corresponding dimension of the middle section 3d, so that around the collar 7b there is still a strip of the middle section not covered by this and the outlet 7 in that in the figure 3 shown crack overlaps only part of the area of the middle section.
  • a closure cover 15 can be screwed onto the connecting piece 7a, with which the cavity 17 present in the container 1 and containing a filling material (not shown in FIG. 2) can be sealed off from the outside.
  • the tube body 3 consists of a two-dimensional composite material which has a layer of cardboard as the main component, which is coated on the inside with a weldable, thermoplastic plastic. An imprint with a description of the filling material and / or other information can be applied to the outside of the walls 3a.
  • the outlet 7 consists of a thermoplastic material which can be welded to the plastic layer of the tube body 3.
  • the filling material present in the cavity 17 and intended for consumption is preferably a liquid or pasty product. However, a powdery product could also be provided as the filling material.
  • the closure cover 15 removed and then the tube body 3, preferably starting from the edge section 3c, pressed together. Since the tube body can be compressed much more easily at right angles to the plane of symmetry 11 than at right angles to the plane of symmetry 13, the container has to be deformed almost inevitably when the filling material is removed in such a way that the compressed sections of each of the two walls 3a assume an approximately flat shape. If, for example, a text is printed on the outside of each wall 3a, this text remains effortlessly legible even when the walls 3a are pressed together.
  • the material forming the tube body 3 is otherwise so elastically and in particular plastically deformable that the tube body essentially retains its compressed shape after a part of the filling material has been pressed out when a person pressing the tube body releases it again. When the tube body is released, practically no air is sucked into the cavity 17, which could damage the filling material remaining in it.
  • first and second workpieces are first produced separately.
  • the first workpiece 21 is formed by a planar, flat blank with a rectangular outline.
  • cardboard is coated on one side with thermoplastic material and printed on the other side, and then cut into the shape shown in FIG. 4.
  • a hole 21a is made in the center of each workpiece 1, for example punched out.
  • notches can be made in the dash-dotted lines are embossed, but these notches can be partially or completely omitted.
  • the dash-dotted lines delimit different zones, in particular the lines 21b delimit a middle section 21c containing the hole 21a.
  • the second workpieces form the outlet 7 of the finished container and accordingly have a socket 23a with an external thread and a collar 23b.
  • the workpiece 23 is made of a thermoplastic and is rotationally symmetrical with respect to the axis 9.
  • the collar 29b of the workpiece 29 runs exactly radially to the axis 9.
  • the collar 23b is elastically deformable, so that it can bend after being fastened to the central section of a first workpiece during the folding process to be described and then assumes the curved shape of the collar 7b which can be seen in FIG.
  • the first workpieces 21 are expediently stacked in their flat shape and transported to the location at which the system for filling the filling material is located. Accordingly, the second workpieces 23 and the sealing caps are also transported to the filling location. The first and second workpieces and the sealing caps are then expediently processed into tube-like containers only immediately before the filling material is filled. This can be done with the same clock frequency as the filling and also with the same machine as the filling. The transport and storage of the first and second workpieces and the sealing cap requires little space in such a workflow.
  • one of the first workpieces is removed mechanically from a stack of first workpieces 21, ie, flat blanks, designated 31 in FIG.
  • a second workpiece is also removed from a storage container containing second workpieces, for example by means of a vibrating conveyor.
  • a second workpiece 23 is inserted into the hole 21a of the first workpiece 21, specifically from the side of the latter coated with plastic.
  • the collar of the second workpiece is pressed with a welding tool 33 indicated in FIG. 8 to the first workpiece lying flat on a support (not shown), the two workpieces being heated at the pressure point and welded to one another.
  • a closure cover 15 is screwed onto the socket of the second workpiece.
  • the first workpiece which is now provided with the second workpiece, is deformed with a tool to form a U-shaped intermediate product 35. As shown in FIG. 9, this deformation can take place in such a way that the two U-legs follow lines that are parallel to one another associated with the U-web containing the middle section 21c.
  • the deformation can be carried out in such a way that there are no permanent kinks in the two parallel lines mentioned.
  • the deformation can, however, also be carried out in such a way that the U-legs are connected to the U-web along the lines 21b and are therefore already convexly curved.
  • the side edges of the U-legs provided with a cross-hatch for identification purposes are pressed against one another with an appropriate tool and welded to one another. This creates an intermediate product 37, which already largely has the shape of the finished container, but is still open at the end facing away from the outlet. So that the U-legs get their convex shape shown in FIG.
  • a core can be inserted between the two U-legs before the side edges are welded.
  • filling material is now filled into the intermediate product 37 from above via a filling line 39 indicated in FIG.
  • the filling line could be connected to the previously mentioned core and the contents could be filled through it, the core being successively moved out of the intermediate product during filling.
  • the edges of the two walls facing away from the outlet and highlighted by cross hatching are welded together. This produces an end product 4l which corresponds to the filled container explained with reference to FIGS. 1 to 3.
  • the sealing caps are only attached to the second workpieces screws when they are welded to the first workpieces. If the holes 21a are made so large that the closure covers can be pushed through them, the second workpieces can be stored with the closure covers already screwed on and then welded to the first workpieces.
  • the tube bodies 3 are produced from first workpieces 21 which are already in the form of separate blanks before the insertion and fastening of the second workpieces 23, which subsequently form the outlet.
  • the tube bodies can also be produced from a strip material forming the first workpiece or, depending on the view, the first workpieces, pieces being separated from the strip material only in a relatively advanced process phase.
  • This manufacturing method is illustrated in simplified form in FIG. 13.
  • 51 denotes a rotatably mounted supply roll of a belt 53. This consists of the same composite layer material as the workpieces 21 and is printed on one side, with equidistantly successive transverse strips 55 being printed identically.
  • the belt 53 is gradually unwound from the supply roll 51 by a transport device, in each case by the width of a transverse strip 55, and transported further.
  • a hole is punched in each transverse strip 55 using a punching device 57.
  • a second workpiece 59 is inserted into this in a subsequent station and then welded on and provided with a closure cover 61.
  • the belt is then deformed, so that a belt section 63 is formed which is U-shaped in a section transverse to the transport direction.
  • the edges of two successive sections forming the cross-hatched sections of two successive transverse strips 55 are welded.
  • 67 filling material is filled in with a filling line.
  • the edge sections facing away from the outlet are welded to one another, the edge section visible from the two edge sections again being highlighted by cross hatching. Only after this phase are pieces cut from the tape with a cutting device, each of which then forms a filled, tube-like container 71.
  • the container 81 shown in FIG. 14 differs from the container 1 in that the edge section 83c of the tube body 83 facing away from the outlet is wider than the edge section 3c and is provided with a hole 83f. This makes it possible to hang the container 81 on a hook or the like.
  • At least one wall of the tube body 93 is widened on the one long side of the cavity of the container, so that there is a wing 93g which is substantially wider than the opposite edge section 93b and one with a Printable additional area forms.
  • a double container 101 is shown in FIG which the tube body 103 delimits two cavities 117, each connected to a closable outlet 107.
  • the two cavities 117 can, for example, contain the different components of a two-component adhesive.
  • an accessory 121 for example a spatula for mixing and applying the adhesive, can be accommodated.
  • the tube body 103 is formed analogously to the embodiment variants described above by two walls connected on the outlet side via central sections.
  • the two cavities 117 are not delimited on their mutually facing sides by welded edge sections, but by strip-shaped, welded intermediate sections.
  • the containers can also have a different outline shape instead of a rectangular one.
  • the tube body 133 of the container 131 shown in FIG. 17 has an approximately horseshoe-shaped outline.
  • the welded edges 133b of the walls 133a can be delimited on the inside by lines which also run in a horseshoe shape.
  • the edges could also be delimited on the inside by lines which, as in FIG. 1, form three sides of a rectangle.
  • containers containing a beverage can be produced with a relatively large volume.
  • the middle sections can then have dimensions which are substantially larger than the outlet, as can be seen from FIG. 3.
  • the middle section 3d is delimited by fold edges 3e which, apart from the places where the edges 3b begin to be continuously curved.
  • fold edges 3e which, apart from the places where the edges 3b begin to be continuously curved.
  • the outlet nozzles normally have round through openings for the filling material in cross section.
  • the outlet ports can also be provided with through openings with a different cross-sectional or mouth shape.
  • paste strips with corresponding shapes can be formed when pressing out a pasty filling material, which may be desirable in certain applications, for example when garnishing cakes.
  • the tube body could also be formed from an arrowhead-shaped blank instead of from a rectangular blank, as shown in FIG. A tube body could then be formed from this, in which the mutually parallel side edges of the walls are of different lengths.
  • first workpieces or blanks could also consist entirely of thermoplastic, weldable plastic instead of plastic coated with cardboard.
