Definitions

  • the invention relates to a method according to the preamble of patent claim 1.
  • the aforementioned method naturally also does not ensure separate disposal of the material of the fuselage part and the lid, which is not necessary in the known method either because the same material is used for both container parts.
  • a container is known from a one-piece cardboard blank and a sealable sealing lid, the closure lid to facilitate the tearing of the container before its assembly is formed containing a predetermined breaking line.
  • the document DE-OS 40 33 170 discloses a container made essentially of cardboard material, the body part of which is produced in such a way that both on it A tear thread which can be grasped by means of a flap is provided at the top edge and at the bottom edge thereof. After the cardboard parts forming a container have been glued, the tear threads serve at least to partially open the container and thus also make it easier to disassemble it.
  • the two publications DE-PS 16 07 925 and DE-PS 17 82 176 deal with sealing covers, each of which is provided along a part to be opened with a predetermined breaking line in the form of a circumferential cross-sectional weakening line and can be placed on the corresponding body part to close a container.
  • the invention has for its object to develop the method of the generic type in such a way that separable containers consisting of at least two different materials can be formed so that the individual materials can be easily separated and recycled.
  • the invention is based on the surprising finding that the closing of two materials to form a container and the creation of at least one line of weakness in at least one of the two materials for later Separation of the two materials can be carried out in one work step in a cost-effective and time-saving manner and without the occurrence of residual stresses and their disadvantageous consequences for the weakening line, even when closing using mechanical forces.
  • the container 10 to be closed in the filled state and to be dismantled in the emptied state consists of a body part 12, a bottom integrally formed with the body part 12 at the lower edge 12b of the same and a cover 14 which extends along the upper edge 12a of the body part 12 for closing the container 10, as shown in Fig. 2, can be placed.
  • the fuselage part 12 and the base essentially consist of cardboard material and the cover 14 consists of sheet metal.
  • Fig. 2 is a closed flange 16 forming connection between the sheet metal lid 14 and the fuselage part 12 made of cardboard material in Partial cross-section shown in the form of a double seam closure, the re-roller 20 of a seam sealing machine used for the closure can also be seen.
  • a circular knife 30 producing a weakening line 12c in the fuselage part 12 is shown in FIG. 2.
  • the container closed according to the invention can be closed at any time by gripping the flange 16 on the one hand and the body part 12 on the other open, whereby at the same time there is a separation between the cardboard material and the sheet metal, except for the area of the flange 16 itself.
  • sheet metal and cardboard material can essentially be disposed of separately and sent to a recycling cycle.
  • the separable container 10 is produced according to the invention as follows:
  • the parts punched out of cardboard material namely the body part 12 and the bottom, are formed into an open container without a cover and firmly glued in this position.
  • a material to be stored is then filled into this open container.
  • the cover 14 formed from sheet metal is placed on the fuselage part 12 along the upper edge 12a thereof.
  • the pre-roll (not shown) of the seam sealing machine thus ensures that the cover 14 rolls up by applying a mechanical force. that the outer edge thereof encompasses the upper edge 12a of the fuselage part 12.
  • the double fold connection shown in FIG. 2 is produced by means of the re-roller 20, again under the action of mechanical force.
  • the circular knife 30, which is connected to the fold sealing machine and is arranged directly below the re-roller 20, causes the formation of the weakening line 12c, which represents a predetermined depression in the body part 12.
  • the weakening line 12c forming a predetermined breaking line is essentially stabilized in the preferred exemplary embodiment of the invention by the formation of the first fold, the formation of the double fold with simultaneous cutting of the cardboard material is possible without any problems.
  • a further circular knife can be connected to the re-roller 20 in such a way that a further weakening line is generated which forms a predetermined breaking line in the lid 14 adjacent to the flange 16. Then the container can be disassembled along the two lines of weakness thus present in sheet metal of the cover 14, in cardboard material of the fuselage part 12 and the bottom, and in a combination of sheet metal and cardboard material of the flanging 16 comprising the double fold connection without the use of further aids. This ensures an optimal separation of the recyclable components of the container 10 in the sense of the dual system.
