Definitions

  • the present invention relates to a container and a lid of thin-walled plastic, which are provided with screw threads.
  • the invention also relates to a method of being able to produce such a container and such a lid cheaply.
  • Plastic is often a preferred material in connection with packagings, above all thanks to plastic's good barrier properties, i.e. the fact that it is impermeable.
  • Liquid-tight plastic packagings of this kind are however relatively expensive if they are provided with threads. It is not possible to manufacture threaded plastic containers cheaply using the prior art. The reason for this is that according to the prior art, injection moulding is used to manufacture such containers. The tools for injection moulding are expensive and complicated to produce, since spark machining is necessary. As a consequence of this, it is attempted to avoid too much machining, which means that the material thickness is often permitted to be greater than the strength actually demands.
  • a major advantage of a container according to the invention is that, thanks to the method of manufacture, the sealing face is completely smooth, in contrast to containers which are produced by means of other methods, for example mould blowing, die casting, in which a discontinuity is always formed in the parting line between the mould parts. Thanks to the invention, a smooth sealing face is thus ensured without edges/burrs.
  • the container is, except for on the threads 5, rotationally symmetrical (which is not however necessary) around the axis of symmetry 9.
  • the closure part 3 also has an annular sealing face 7, which is continuously smooth or devoid of discontinuities.
  • the sealing face 7 is arranged rotationally symmetrically around the axis of symmetry 9 and has a normal which is essentially parallel to the axis of symmetry.
  • the sealing face 7 is also disposed between the wall section 4 of the container part 1 and an upper wall section 14, which upper wall section 14 has a greater diameter than the wall section 4.
  • the free end 13 of the collar 10 has the largest diametrical dimension of the container and thereby providing that the sealing face 7 is arranged inside of said free end 13.
  • Fig. 2 shows the lid 20 for the container in Fig. 1.
  • the material in the lid is preferably the same as in the related container.
  • the lid 20 comprises a closure part 22, which is provided in a collar-like section with internal threads 26, corresponding to the threads 5 in Fig. 1, and an essentially level lid part 24 with an underside 24A and an upper side 24B.
  • the closure part 22 also comprises an annular section/a sealing face 28 which is continuously smooth or devoid of discontinuities and is arranged in a transition zone 30 between the lid part 24 and the closure part 22.
  • Both the lid part 24 and the sealing face 28 are disposed rotationally symmetrically around an axis of symmetry 9.
  • the sealing face 28 consists of an annular section which projects, i.e. forms a sealing ridge, below the underside 24A of the lid part. This construction provides rigidity at the same time as it leads to effective sealing between the sealing face 28 of the lid and the corresponding sealing face 7 of the container.
  • the wall section 32 of the lid has a longer vertical extension than the corresponding upper wall section 14 of the container, due to which the lid can be screwed so far down onto the container that the sealing face 28 of the lid is pressed together with the sealing face 7 of the container, without any risk that the upper edge 12 of the container shall come into contact with the corresponding part 34 of the lid 20.
  • the sheet with the formed articles is ejected from the forming tool to be moved to the subsequent punching operation.
  • Ejection from the forming tool is normally effected by means of so-called ejectors, which are separate units interacting with the forming tool.
  • said ejector tools can be eliminated by using the threads to eject the sheet. This is carried out by rotating the threaded part of each form in the forming tool. This can be achieved either by rotating the entire form area or by only rotating the threaded part.
  • the advantage of only rotating the threaded part is that the container part 1 can then be allowed to assume shapes which are not rotationally symmetrical, for example a hexagonal shape, which results in a certain stiffening.
  • the invention is not restricted to the embodiments shown, but can be varied within the scope of the following claims. It is perceived for example that the number of thread ridges can be varied within wide limits, all the way from one to a multiplicity. Furthermore, it is perceived that many conceivable shapes other than hexagonal containers 1 can be manufactured according to the method according to the invention, for example triangular, star-shaped etc. In addition, it is perceived that the collar can be arranged to extend a substantial distance, it being possible in an extreme case, with a downwardly directed collar, that the threads would be able to be arranged around the lower part of the container.
