Definitions

  • the invention relates to a package for flowable filling goods with a tube formed by at least one longitudinal sealing seam, at the ends of which the bottom and lid are attached, of which the lid consists of thermoplastic material without carrier material, is injection-molded onto the tube along its upper edge and has a pouring device, wherein the tube made of at least one side coated with thermoplastic material, z. B. cardboard exists, the bottom is square and is formed from the folded tube of the pack as a folding closure, a part of the tube wall adjoining the upper edge of the tube folded onto itself and connected to a double-walled, triangular base strip and where the molded cover is extended with a web over the top edge of the double-walled base strip.
  • packs e.g. B. liquid packs for milk, juices and the like, known, of which one embodiment is designed for a pack volume of about two liters of liquid.
  • this known package similar features are specified as mentioned above.
  • the triangular, double-walled base strip mentioned is itself provided with a gripping opening, so that in other words the handle for this pack, which is heavier in weight (2 liters of liquid), is made from the material of the tube.
  • the lid of the package In the meantime, one had already considered designing the lid of the package to be quadrangular in plan view or halving it so that the flat lid surface takes on a triangular shape, with a handle being provided in the cut-off half of the lid.
  • the lid of the package In the meantime, one had already considered designing the lid of the package to be quadrangular in plan view or halving it so that the flat lid surface takes on a triangular shape, with a handle being provided in the cut-off half of the lid.
  • sealing and manufacturing problems have arisen, so that the optimal solution has not yet been found.
  • the invention is therefore based on the object of improving the package of the type described in the introduction in such a way that, by simplifying the cutting or the cutting work on a material web, the tightness and strength of the package can be increased, preferably also using as little plastic material as possible.
  • the lid has at least three corners and at least a first and a second plane having a handle, which enclose an angle and of which the first plane is parallel to the plane of the floor, the second plane at least partially is formed from the tube material and that the handle is connected to the lid and is injection molded together with it within the cuboid outer contour of the pack on the double-walled base strip, the rear edge of which is facing the handle is closed.
  • the double-walled base strip was formed into a V-shape by cutting a tube wall from the top edge, and after the two walls of the base strip had been laid one on top of the other, the base strip had an open edge at the rear facing the handle. Tools had been developed to allow the two walls to be aligned and fastened to form the base strip, but the folding work was relatively difficult and the strength of the packing in the area of the handle was also not the best solution.
  • the double-walled base strip should, on the one hand, preferably be connected to itself by heat sealing, and on the other hand, efforts are made to inject the lid and, if possible, the handle as well. This is achieved according to the invention in a single operation, because when the tools for injecting the cover are closed, the folding of the double-walled base strip is automatically taken care of and at the same time towards the others Machine functions performed.
  • a tube for such a pack is known, for example, in the case of a liquid pack.
  • a tube is formed from the rectangular, flat cardboard blank by embossing lines and folding in that a longitudinal sealing seam is created on one edge of the tube.
  • this is preferably placed in an edge which runs towards one of the four corners of the cover.
  • this can be the edge which is arranged under the pouring opening or the pouring edge, it is particularly preferred to use one of the two adjacent tube edges, which are thus arranged between the front and rear of the pack.
  • the front of the pack here is the side with the pouring opening; while the back is the one with the handle.
  • the tube initially has no welded connections. It is understood by the person skilled in the art that the sealing problems with liquids as filling material are thereby considerably and advantageously reduced.
  • the bottom as a folding closure and also when the cover is molded on, further welding processes are of course carried out and weld seams are made, but overall the package according to the invention has a minimal number of weld seams with a corresponding tightness guarantee of the package.
  • the handle has an upper horizontal and a rear, the pouring edge diametrically opposite vertical web, which comprise the gripping opening, which has a size for the passage of at least three fingers of an adult's hand.
  • the handle now has, inter alia, an upper, horizontal web lying in the plane of the lid, which extends the diametrical line from the pouring device over the middle of the lid to the opposite rear corner. This creates a support line, whereby the stacking possibility of several packs according to the invention is improved.
  • the load-bearing capacity of the lower pack is improved because the vertical forces can now be guided by the weights of the upper packs into the very load-bearing edges of the pack below.
  • the gripping opening should not be smaller.
  • a much larger gripping opening, on the other hand, requires more manufacturing material and dead volume for transport.
  • the double-walled, side view triangular base strip next to the handle has a right angle in side view and its hypotenuse with the longitudinal center axis of the tube includes an angle that has a size of 20 ° to 40 °, preferably from 25 ° to 35 °.
  • the blank is rectangular, so that the outer edges of the blank each form right angles with one another, after the tube is folded, the triangular base strip creates a kinked line on the upper edge of the tube, to which the lid must be molded. This is created by using part of the wall material for the triangular base strip.
  • this latter angle between the longitudinal central axis of the tube and the hypotenuse or second plane has a size of 29 ° or 30 °. Then you can create a sufficiently large gripping opening for the three fingers of the hand.
  • the size of the gripping opening is related to this angle, the cross-sectional dimension of the package, which is preferably a square, also being an essential factor for determining the size of this angle.
  • the thickness of the handle in a way determines the angle, which the manufacturer generally strives for as much as possible, but is subject to clear restrictions due to the aforementioned factors.
  • At least the upper horizontal web of the handle in the plane of the cover has a lateral width of 2 to 20 mm preferably from 6 mm to 12 mm. This gives the handle a resistance to bending in the direction perpendicular to its main surface, so that it protrudes from the inclined, so-called second plane essentially at 90 ° and remains essentially rigid in this position.
  • the strength can be further increased according to the invention if reinforcing ribs are injection molded onto both sides of the double-walled base strip. In this way, one can avoid the full encapsulation of the base strip and still obtain the same structural advantages. So plastic material is saved and the strength is not sacrificed.
  • both webs of the handle are provided with reinforcing ribs and preferably there is a free space without material between the lower end of the vertical web and the intersection of the second plane with the tube edge.
  • the embodiment of the invention is also very advantageous, according to which the pouring opening is provided with a pouring opening handle of oval shape in plan view and the ring flange formed on the pouring opening cover is arranged in the region of its outer edge and follows this oval shape.
  • the oval design of the pouring opening, and thus the pouring opening cover and thus its ring flange formed on the edge of it at the bottom improves the tightness when the package is reclosed, because the oval shape results in higher side tensions of the material, which improve the clamping forces and thus of tightness.
  • the tube 1 of the pack shown forms the four side walls thereof, of which only the front two walls, one of which can be seen in FIG. 1 and is designated by 1a, is rectangular.
  • the other side walls, labeled 1b and 1c in FIG. 3 have a trapezoidal shape. They are connected via the rear edge 2, which represents a folded edge. It ends at the top at point P, which represents a section of the so-called second plane 3 with the rear edge 2. More precisely, this second level 3 is formed by the two triangular surfaces 3a and 3b, which are connected to one another via the double-walled, triangular base strips 4.
  • the bottom of the pack is formed by the fold lines and wall panels shown in FIG. 1 below.
  • the cover bears the reference number 6.
  • the shape of the cover 6 is triangular, as can clearly be seen in FIG. 2. It forms the so-called first level, which is identical to the level of the cover 6 and horizontal, i. H. is parallel to the surface of the finished bottom 5, not shown.
  • the lid 6 has the pouring opening 7 with pouring opening lid 8 of oval shape in plan view (FIG. 2), outer edge 9, opening tab 10, pouring edge 11 and ring flange 12 on. It can be seen from the partial sectional view in FIG. 1 that the ring flange 12 extends in the region of the outer edge 9 of the pouring opening cover 8 and thus follows its oval shape.
  • the handle 14 is integrally molded on the cover 6, is made of plastic and is therefore also directly connected to the two small triangular wall panels 3c and 3e, which together with the triangular wall panels 3a and 3b form the so-called second level, which is denoted overall by 3.
  • 2 shows the length of the horizontal web 13, which extends from the center of the package, where the longitudinal central axis 15 intersects with the lid, to the rear corner 16. Below this is the vertical web 17, which is molded onto the double-walled base strip 4 via a plastic molding 18.
  • FIG. 1 In the side view of FIG. 1, one can also see the reinforcing ribs 19 molded on both sides of the double-walled base strip 4 together with the handle 14 and, in the area of the vertical web 17, also broken off, also the reinforcing ribs 20, which extend between the outer walls of the web, from FIGS and 3 also sees the width B of the webs 13 and 17 extending in the first plane of the cover 6.
  • the gripping opening 23 is designed in such a way that a good three fingers of an adult's hand can pass through it, so that the pack can be handled well even when filled with a capacity of up to 2 1/2 liters.
  • the upper edge of the tube 1, designated 26 in FIGS. 1 and 3, is straight and horizontal in the region of the two front side surfaces (the one front side surface 1a can be seen in FIG. 1), while it is like over the two triangular wall panels 3a and 3b a wide, open V runs over which the two plastic wall panels 3c and 3e are connected.
  • the rear edge of the double-walled base strip 4, designated 27, is closed.
  • the upper edge of the double-walled base strip 4 is designated 28 ( Figure 1).
