Definitions

  • the invention relates to a double-walled container with two pot-shaped containers arranged at a distance from one another and adapted to one another, at least one of which is polygonal and has approximately rectangular wall sections.
  • the invention has for its object to show such a container that is easy to manufacture.
  • At least the peripheral wall of the polygonal container consists of a one-piece blank, is formed without a longitudinal seam and has radially projecting approximately triangular gusset surfaces which are bent along fold lines relative to the rectangular wall sections by approximately 90 ° and are located on the wall support the other container.
  • both container walls are supported against one another by simple means, whereby a relatively stiff double-walled container is formed, the spacers of which inevitably arise when one container is erected.
  • the triangular gusset surfaces can protrude radially inwards and are supported with their inner edge on the wall of the further container.
  • the triangular gusset surfaces protrude radially outward and to have their outer edge supported on the inside of the wall of the further container.
  • one or the other embodiment will bring advantages.
  • the inner container is to be made liquid-tight, it will preferably be thermoformed from plastic and the outer container will be folded and provided with the gusset surfaces.
  • the inner container - for example as a package for ice cream - should be able to be folded out into a flat shape after removal from the outer container, the inner container will be equipped with the gusset surfaces projecting outwards.
  • the diameters of the two conical containers to be inserted into one another and the dimensions of the gusset surfaces are matched to one another such that the bottoms of the two containers are also spaced apart.
  • the container part equipped with the gusset surfaces can be produced in a simple manner, for example by simply pushing the flat blank through a folding shaft.
  • scoring lines are expediently arranged on the outside of the respective folding line, as a result of which folding is made even easier.
  • the container 1 shown in FIG. 1, which is open at the top and polygonal in cross-section, has wall surface sections 2, between which two triangular gusset surfaces 4 which are articulated via a folding line 3 are arranged.
  • the folded gusset surfaces 4 protrude radially outward from the container 1.
  • the container 1 consists of a one-piece blank. However, it is also possible to form the peripheral wall in one piece and without longitudinal seams and to insert the bottom of the container.
  • Fig. 2 shows the container 1 with the wall surface sections 2 and the triangular gusset surfaces 4, which are glued together in this embodiment.
  • the container 1 is inserted in a further, larger container 5. Due to the radially outwardly protruding gusset surfaces 4, 5 insulating spaces 6 are divided between the wall surface sections 2 of the container 1 and the inner wall of the container.
  • FIG. 3 shows a container 10 in which triangular gusset surfaces 40 are arranged between rectangular wall surface sections 20. These gusset surfaces 40 are folded onto one another and project radially inwards from the wall of the container 10. Another, smaller container 50 is inserted into the container 10. Between the outer wall of this smaller container 50 and the inner sides of the wall sections 20 of the container 10, insulation spaces 60 are partitioned off by its gusset surfaces projecting radially inwards.
  • FIG. 4 shows a cardboard blank 101 which is designed as a circular disk.
  • a disk-shaped section is provided, which is provided as the bottom 102 for a container to be folded from the cardboard blank.
  • the bottom 102 is separated from the rest of the cardboard blank 101 by a perforation line 104, via which essentially rectangular side walls 105 are hinged to the bottom 102.
  • Two gusset surfaces 106, 107 are arranged between each two of these side walls 105 and are connected to one another via a perforation line 108 and to the adjacent side walls 105 via further perforation lines 109 and 110.
  • the gusset surfaces may protrude inwards or protrude outwards.
  • scoring lines 118, 119, 120 via which the gusset surfaces 106, 107 are connected to one another or to the adjacent side walls 105.
  • scoring lines have the advantage over the perforation lines that the cup is still largely sealed. It is also possible to provide a scoring line between the bottom 102 and the side walls 105 instead of the perforation line 104.
