Definitions

  • the invention relates to a packaging for liquids, consisting of side walls connected to one another via at least one longitudinal sealing seam and attached to the ends of the tube, a cover with a round cross section and a square bottom end walls, the side walls being formed from cardboard coated at least on one side with plastic , while the lid is made of thermoplastic material without a carrier material and is attached along its outer edge to the side walls.
  • packaging has also been developed which has a round lid at one end of the tube and a quadrangular base at the other end (DE-OS 32 17 156.0).
  • the present invention has for its object, a simple means without additional material. to create more stable, stable and easier to grasp j pack, even if one end wall is round and the opposite is square.
  • This object is achieved in that in opposite areas in the tube, extending over the entire height of the tube and parallel to its central axis long folding lines are provided and that starting from the four corners of the bottom, F ormübergangs folding lines are arranged in the tube, the Bottom over 1/3 to 2/3 of the height of the tube in the direction of the lid are arranged.
  • the so-called long fold lines facilitate the formation of the tube, because the mandrel using the measures according to the invention does not necessarily have to have a circular cross-section but can also be oval or at least quite flat at the edges, so that there are manufacturing advantages, but still the shape of the all-round closed tube (via the longitudinal sealing seam) can be reached because the long fold lines on the areas of the mandrel come to lie with great curvature and allow perfect folding.
  • the spontaneous crease lines resulting from the folding can even run in the direction transverse to the general longitudinal axis of the packaging; if necessary, even with longitudinal components. In each Trap then results in an uncontrollable shape of the package with a correspondingly high risk of leaks.
  • the shape transition folding lines also have the advantage that they produce a rounding of the material in cross-section during manufacture by means of an embossing stamp, with the result that the material can be pulled apart transversely to such a rounded embossing (straight line), the material like a spring works. Material is accumulated in the region of the embossed shape transition fold line which is rounded in cross section, as a result of which the material is shortened in the direction transverse to this embossed fold line, which allows an extension without damage to the material in the sense of the spring mentioned above.
  • the two long fold lines are diametrically opposite one another and are preferably arranged between two shape transition fold lines.
  • This symmetrical arrangement facilitates production, and an almost flat sheet can then be used as a mandrel when forming the tube. Due to the even spacing of the fold lines, the material is distributed evenly or the design can be changed in a uniform manner.
  • the two long folding lines run through the tips of two triangular flaps arranged opposite one another, which result from the block bottom folding of the bottom with a transverse sealing seam.
  • the elasticity which starts from the long fold line on both sides, has an effect over the entire material range up to the tips of the triangular lobes.
  • the longitudinal sealing seam is arranged between two shape transition folding lines and at a distance from the long folding lines.
  • the longitudinal sealing seam can be arranged approximately in the middle between the pair of shape transition folding lines in such a way that the pair of long folding lines is arranged further out at a distance.
  • the finished pack for flowable filling goods shown in FIGS. 1 and 2 consists of a total of 1 side walls, a distinction being made between field 1b and side field 1a in FIG. 3 on the right and in FIGS. 4 and 5 at the front.
  • the pack In the area of the lid 2, the pack has a round cross section, because the lid 2 is also circular in plan view. On the end wall side forming the bottom 3, one cannot distinguish between the four side walls because the cross section is round there.
  • the side walls 1 are formed into a tube and connected along the longitudinal sealing seam 4 for the final formation of the closed tube. From Figures 2, 4 and 5 it can be seen that the longitudinal sealing seam 4 in the bottom 3 he stretches. This also results from the blank shown in FIG. 3.
  • the tube has the height H in the shape of FIG. 2, which, taking into account the shaping before the completion of the base 3, is of course smaller than the total height of the blank of FIG. 3, measured from bottom to top.
  • the height H of the tube is measured from the top edge 6 of the lid 2 to the fold line 7, i.e. to the level of the fully folded block base 3.
  • the height between lines 5 and 7 according to FIG. 3 disappears.
  • the double cardboard strip 8 (FIGS. 3 to 5) is formed in the block bottom forms known per se, in which the barely visible in FIG. 2 and in FIGS. 3 to 5 are shown there is a dashed short line indicated cross seal 9.
  • the triangular lobes 10 are also formed here.
  • the bottom-side end wall (the bottom 3) to the state of Figure 4, after which the triangular flaps 10 to the outermost tips 21 on the base 3 (shown in FIG 2) or the side walls (according to FIG. 5) folded over there, for example: can be attached by spot heating.
  • the lid 2 is already sealed liquid-tight before filling. It can either be prefabricated, pulled from the warehouse and sealed to the round tube, or it can be molded directly onto the round end of the tube.
  • the cover 2 is constructed only from thermoplastic and without a carrier material. The cover is molded on in the form of the form of use in which the opening device is folded outwards as shown in FIG. 1. This facilitates the opening process when in use.
  • the pouring device is generally designated 13 and, after injection or sealing, is folded in before the package is turned over to the state of FIG. 2 so that no individual parts of the pouring device 13 protrude beyond the outer edge 6. This guarantees perfect stability and good packaging (using shrink wrap or the like).
  • the longitudinal sealing seam 4 - if one considers FIGS. 4 and 5, for example - lies between the two adjacent shape transition folding lines 20, of which only the “short” line shown in FIGS. 4 and 5 is shown in the same, and in the same Distance from the long fold lines 18, of which only the line arranged at the front right is shown in FIGS. 4 and 5.
  • the right edge 4 'of FIG. 3 lies in the course of the longitudinal sealing seam 4, so that the specified positional relationships of the short shape transition folding lines 20 to the long folding line 18 or to the longitudinal sealing seam 4 can also be seen.
  • the long fold lines 18 alone and in connection with the shape transition fold lines 20 have the essential advantage that they represent a stiffening of the handle for the user. If one takes into account the direction of flow of the pouring jet after opening the opening device, then these folding lines, in particular the long folding lines 18, lie at the top in the grip area of the user perpendicular to the direction of flow of the pouring jet. As a result, the new pack can be held much better, and the user has the feeling of greater security and therefore has better control over the movements with the new pack.
