Definitions

  • the frame is so strongly compressed in the region of one or both of the segment edges of the overlapping region that the cavity still present on the segment edge prior to the pressing is completely filled with sealing material.
  • the edge portion of the overlap region is subjected to increased pressing pressure, in which the inner segment edge, which is also accessible from the interior of the container, rests on the outer side of the closure element.
  • the frame is thereby also completely liquid-tight in the overlap area.
  • the protruding projection in the radial direction is usually provided on a circular cross-section in the form of a press surface, over which the projection then protrudes in the radial direction.
  • the height of the pressing surface usually corresponds to the height of the frame.
  • the pressing surface may also be divided into a plurality of circular section-shaped strips, which then either all or only a few have a projection which projects in the radial direction.
  • the recess then produced by such a ram on the inside of the frame is grooved and over the height of the frame, a plurality of grooves can be embossed. In such groove-shaped impressions is then essential that in the region of the embossed grooves no cavity is present at the inner edge of the segment. If cavities are still present between the groove-shaped indentations, this no longer plays any role for the tightness of the frame.
  • the arrangement of the press ram with the at least one projection on a radially inner side of the frame has proven to be advantageous.
  • the convex curvature can be adapted to a curvature of the inside of the frame, so that the curvature of the protrusion corresponds substantially to the radius of curvature of the frame. As a result, over the width of the projection seen a uniform pressing pressure can be generated.
  • the projection projects in the radial direction by a height over the remaining surface of the press ram, which is between 0.5 times and 1.5 times, in particular 1 times, the thickness of the flat segment for the Coat is.
  • the projection in the circumferential direction is arranged relative to the overlapping region such that only one of the segment edges of the jacket is subjected to an increased pressing pressure in the overlapping region.
  • the projection is arranged symmetrically to an edge of the overlapping region.
  • a width of the recess in the circumferential direction is 0.5 times to 1.5 times the width of the overlapping area.
  • the recess may have rounded side edges in order to avoid pressure points and damage to the material in the region of the frame.
  • the recess is less than 1 times the width of the overlapping area, the recess is not usually placed opposite the projection.
  • a method for producing a container from paper material or paper-like material with the following steps: winding a planar segment into a jacket, so that the segment edges arranged on the longitudinal sides overlap and thereby form an overlapping region, connecting a cup-like closing element, namely a cup-like bottom and / or a cup-like lid, with the jacket by means of a frame, so that the jacket and the closing element are substantially liquid-tightly interconnected, pressing and sealing the shell and the closing element in the frame with at least one press ram, wherein the frame is acted upon by substantially radially directed pressing pressure, and loading at least one edge portion of the overlapping region of the jacket in the region of the frame with an increased compared to the rest of the frame pressing force.
  • the projection protrudes from the remaining pressing surface of the punch.
  • the pressing surface may also be formed by means of a plurality of strip-shaped projections which then all or only partially have a projecting in the radial direction projection.
  • the pressing surface can, for example, be circular-section-shaped in cross-section, with the projection then protruding out of this circular-segment-shaped pressing surface.
  • the application of a region on the inside of the frame is provided with the increased pressing pressure, which lies opposite the inner segment edge of the jacket, which rests on the outer side of the closing element.
  • This inner segment edge which rests on the outer side of the closing element, extends in its further course into the interior of the container and thus comes into contact with any liquid present in the container. If, according to the invention, this inner segment edge is subjected to the increased pressing pressure, voids and hence leaks in this region can be reliably avoided.
  • the region which is acted upon by increased pressing pressure is arranged symmetrically to the edge of the overlapping region, on which the inner segment edge of the jacket, which rests on the outer side of the closing element, is arranged.
  • a secure pressing can be achieved and in particular can be achieved that a cavity which is formed in front of the inner segment edge of the shell is completely filled with sealing material during pressing.
  • the application of a region of the frame with the increased pressing pressure is provided, the width of which amounts to 0.25 times to 0.75 times, in particular 0.5 times, the width of the overlapping area.
  • the presentation of the Fig. 1 shows a side view of a container according to the invention, which is designed here as a cup 10.
  • the cup 10 has a frusto-conical shell 12, which is provided at its upper edge with a so-called mouth roll 14.
  • the jacket 12 is wound from a flat segment, as for example in Fig. 2 and Fig. 3 is shown. The longitudinal edges of this segment are superimposed during winding, so that an overlap region 16 is formed.
  • the jacket 12 has a frustoconical shape after winding.
  • the lower end of the shell 12 is turned over by 180 °.
  • the folded around the bottom collar 24 shell 12 and the bottom collar 24 are then first heated by means of hot air and then pressed together.
  • the paper material of the bottom 18 and the shell 12 is provided on at least one side with a plastic coating, such as polyethylene.
  • the thermoplastic plastic coating is heated and when pressing jacket 12 and bottom 18 shell 12 and bottom 18 are then sealed together in the so-called frame 20. This happens because the heated polyethylene coatings or coatings of otherwise a suitable thermoplastic material merge together and thereby connect the shell 12 and the bottom 18 in the region of the bottom edge 24 or better in the region of the frame 20 substantially liquid-tight.
  • the upper end of the shell 12 can also be turned over a cover collar of a lid. This is done in containers according to the invention which are designed as cans. A lid would then just the reverse of the bottom 18 inserted into the jacket, so that the lid collar protrudes from a top plate up and the top of the shell would then 180 ° wrapped around this cover collar and the cover collar and the upper turned end of Mantels would then be pressed into a frame and sealed.
  • the presentation of the Fig. 4 shows a section-wise view of the cutting plane AA in Fig. 1 before the pressing of the frame 20. Shown is the sectional plane AA in the overlapping area 16.
  • the jacket 12 is, see also Fig. 1a , with its lower end wrapped around the end of the Bodenkragens 24.
  • the second segment edge 30 rests on an outer side of the bottom ridge 24 and then passes through the bevel 32, not visible in the Fig. 4 , in the circumferential direction to the right. On the inside, the second segment edge 30 is due to the slope 32 then in the circumferential direction spaced from the second segment edge 30 on the inside of the Bodenkragens 24 at.
  • the first segment edge 28 is located on the outside of the bottom edge 24 in the radial direction spaced from the bottom collar 24 and also on the inside of the bottom edge 24, the first segment edge 28 is spaced from the bottom collar 24.
  • the region of the segment which adjoins the first segment edge 28 has a step-shaped region 46, 48. This region 46 on the outer side of the bottom ridge 24 and also the region 48 on the inside of the bottom ridge 24 are each arranged in the region of the second segment edge 30 and still belong to the overlapping region.
  • the overlapping area 16 ends in Fig.
  • a cavity 50 lies in the stepped area 46 in front of the second segment edge 30.
  • This cavity 50 has an approximately triangular cross-section and is formed by the step-shaped region 46.
  • Fig. 4 shows on the radially inner side of the frame 20 a conventional ram 54.
  • This conventional ram 54 is radially outward, in Fig. 4 so moved down to press the frame 20 and seal.
  • a plurality of circular segment-shaped ram 54 are provided, which are then arranged on the inside of the frame 20 are moved radially outward. Nevertheless, the liquid-tight design of the frame 20 is problematic.
  • Fig. 5 shows a in the region of the frame 20 of the representation of Fig. 4 corresponding representation of the shell 12 and the Bodenkragens 24. The jacket 12 and the bottom collar 24 are therefore not explained again.
  • the state after pressing the frame shows the representation of Fig. 6 ,
  • the frame 20 in the not yet compressed state of Fig. 5 heated, for example, applied from the bottom with hot air.
  • a radially outwardly directed pressing pressure is then exerted on the frame 20, which in Fig. 6 is symbolized by the arrow 62.
  • a radially outwardly directed pressing pressure is exerted by means of the press ram 56 or a plurality of ram 56.
  • Fig. 6 shows the already finished pressed and sealed state of the frame 20. It is good to see that the cavity 50 in front of the inner segment edge 30 on the outside the Bodenkragens 24 is completely filled with sealing material, the in Fig. 6 is shown in black.
  • the cavity 52 on the inside of the Bodenkragens 24 in front of the segment edge 30 in the region of the chamfer 32 is not completely filled with sealing material, since only the lower pressure in the radial direction was exerted outward. As already mentioned, however, this cavity 52 is not critical for the tightness of the cup.
  • Fig. 7 shows the cup in the region of the frame 20 with the ram 56 in the already compressed state of the Fig. 6 , Press punches 56 and frame 20 are therefore not explained again.
  • a counterpart 70 is arranged opposite the press ram 56.
  • the counterpart 70 has a concave shape, wherein the radius of this concave shape corresponds approximately to the outer radius of the frame 20.
  • the presentation of the Fig. 8 shows the arrangement of Fig. 7 , wherein instead of the counterpart 70, a counterpart 72 is shown, which has on its, the frame 20 side facing a recess 74.
  • the recess 74 is about as wide as the overlap area 16 on the outside of the frame 20, which in Fig. 8 is below. Through the recess 74, the overlap region 16 can be received in the counterpart 72 and the increased pressing pressure in the region of the arrow 62 can be concentrated on the region of the cavity 50.
  • the recess 74 has rounded side edges, so that damage to the outside of the frame 20 can be avoided.
  • the recess 74 has a depth which corresponds approximately to the material thickness of the segment 26 for producing the outer jacket 12. Thereby a secure pressing and sealing in the region of the cavity 50 can be achieved without the risk that the material of the jacket 12 in the region of the overlap 16 will be damaged by excessive pressing pressure.
  • the coat 74 of the Fig. 9 formed from a segment whose second segment edge 30 is provided with a sealing strip 76.
  • the sealing strip 76 consists of a sealable thermoplastic plastic, for example polyethylene.
  • the sealing strip 76 is wrapped around the second segment edge 30, so that the sealing strip thus extends on both sides of the segment edge 30 a distance along the overlapping region 16.
  • additional thermoplastic material is still available when the frame 20 is pressed in order to completely fill the cavity 50 with sealing material, in this case polyethylene, in front of the inner segment edge 30, which rests on the outside of the floor collar 24.
  • the provision of the sealing strip 76 thereby enables an even more reliable sealing of the frame 20 relative to the interior of the container according to the invention.
  • the sealing strip 76 is therefore preferably used in cans of paper material or paper-like material to be filled over a longer period of time as a cup with liquid.
  • a can of the jacket 74 would not only be connected to the bottom collar 24 by means of the frame 20, but, as already explained, also be liquid-tightly connected to a cup-shaped lid by means of another frame.
  • the inner segment edge 30 is then provided with the sealing strip 76 in order to achieve a particularly liquid-tight design of the frame in the region of the lid.
