Definitions

  • the invention relates to a method for the liquid-tight sealing of a container formed from one or more blanks with at least one axially extending longitudinal seam, which is formed by overlapping gluing, sealing or the like of the two edge sections of the blank and which is closed by a thin-walled cap-shaped part on at least one end face is.
  • the invention has for its object to show a method and a container in which the closure can be carried out inexpensively and still reliably.
  • peripheral wall of the cap-shaped part is pressed onto the wall of the container during sealing or the like into the recess that exists alongside the longitudinal seam and corresponds at least to the wall thickness of the container.
  • the formation of the container with an axial longitudinal seam inevitably creates a recess directly next to this longitudinal seam on the inside of the container. It would be difficult to adapt the cap-shaped part of this container shape from the outset and, especially for bringing the two parts together - the container wall and the cap-shaped part - would be very complex.
  • the solution according to the invention enables the container to be sealed in a manner which is simple to carry out but nevertheless acts reliably.
  • the peripheral wall of the cap-shaped part is pressed into the recess of the container by means of a material strip which is inserted into or molded onto the sealing tool or the like and corresponds to the wall thickness of the container.
  • the wall of the cap-shaped part inserted into the container can be pressed into the recess of the container by means of an attachment molded onto the container wall and folded over the wall of the cap-shaped part.
  • any sealing tool or the like can be used to press in the cap-shaped part.
  • An adaptation of the tool to the return or a coordinated control of the return and tool could then be omitted.
  • a particularly advantageous embodiment of the container according to the invention is that the cardboard disc is slightly larger in diameter than the inside diameter of the container and surrounds it in a circumferential groove of the container.
  • the section of the container wall which projects beyond the cardboard disc can be rolled inwards.
  • the cardboard disc can be supported against this rolled-up section of the container wall.
  • the cardboard disc can thus optionally be fixed via the circumferential groove or the rolled section of the container wall. A combination of these two fasteners is also possible.
  • An advantageous embodiment of the container according to the invention is that an extension is formed on the blank forming the container wall next to the longitudinal container seam, the protruding length of which corresponds at least to the axial length of the wall of the cap-shaped part and is applied to the inside thereof.
  • attachment has a perforation in the connection line with the container blank.
  • the opening of the container can be made even easier according to the invention if the protruding length of the extension is greater than the axial length of the wall of the cap-shaped part and the extension with its section facing away from the container wall lies against the radial section of the cap-shaped part.
  • this section can be gripped and the container opened.
  • FIG. 1 in FIG. 1 denotes a container which has a circular cross section and whose container wall 2 is formed from a rectangular blank.
  • the container wall is closed along an axially running longitudinal seam 3.
  • this longitudinal seam 3 the two facing edge strips of the blank are arranged to overlap one another. This overlap creates a recess 4 on the inside of the container immediately next to the longitudinal seam 3.
  • a cap-shaped part 5 is provided with a peripheral wall 6 which bears against the container wall.
  • an extension 7 is formed on the container wall 2, which is folded inwards and bears against the free side of the peripheral wall 6.
  • peripheral wall 6 and the container wall 2 are pressed against one another for mutual sealing, the peripheral wall is pressed into the recess by the interposition of the extension 7 between the peripheral wall 6 and a sealing tool or the like (not shown). This is shown in FIG. 3, where the peripheral wall 6 is pressed into the recess 4, however, by an appropriately trained one the sealing tool 8 molded material strips.
  • This strip of material could also only be inserted between the sealing tool or the like and the peripheral wall 6.
  • the end piece of this projection 7' can - as shown in Fig. 2 - on the radial portion of the cap-shaped part 5 can be created.
  • the end of the extension 7 ' can then be grasped to open the container and the container can be torn open.
  • a perforation 9 is provided in FIG. 1 at the bending point of the extension 7 in order to facilitate tearing open the container along the longitudinal seam 3, for example.
  • an impressed bending line (not shown) can also be provided.
  • FIG 4 shows an exemplary embodiment in which a cardboard disc 10 is provided to reinforce the cap-shaped part.
