Definitions

  • the invention relates to a novel method for producing packaging elements and packaging.
  • packaging elements are regularly produced from blanks of a packaging element material.
  • One example is the production of finished shells, which are made from cuts of flat raw materials.
  • the processing of blanks in the production of packaging elements has the disadvantage that a transport system is required to transport the individual blanks.
  • Such transport systems are often quite complex.
  • the endless material itself offers a very good opportunity to be conveyed from one station to the next station in a processing device by running the endless material through the various stations.
  • certain materials cannot be provided as continuous material on a roll or this type of provision involves other disadvantages.
  • the object of the present invention is to at least partially solve the problems described with reference to the prior art. This object is achieved with the invention according to the features of the independent claims. Further advantageous refinements are specified in the dependently formulated claims as well as in the description and in particular in the description of the figures. It should be noted that the person skilled in the art combines the individual features with one another in a technologically sensible manner and thus arrives at further refinements of the invention.
  • a method for producing a packaging element from a prefabricated flat material and a carrier material comprising the following steps: a) providing the prefabricated flat material; b) connecting the assembled flat material to the carrier material, which is provided as an endless material; so that a first composite is created from the assembled sheet material and the carrier material; c) Carrying out at least one transport of the assembled sheet material with the carrier material; and d) carrying out at least one processing step in which the first composite is processed so that a second composite forming the packaging element is produced from the assembled flat material and the carrier material.
  • the assembled flat material is flat and therefore particularly flat. When we talk about the “fabricated material” below, this always means the “fabricated flat material”.
  • the assembled flat material preferably has no elevations and depressions or indentations and bulges (that go beyond manufacturing tolerances).
  • the thickness of the assembled flat material is uniform (within manufacturing tolerances).
  • the manufactured material forms, for example, a surface section.
  • it is a material that would in principle also be suitable for processing as a continuous material - for example, it is a material that can be provided on a roll or a coil and which, however, is assembled or divided.
  • the carrier material is preferably a deep-drawable material which can be processed in the processing steps according to step d) together with the manufactured material and does not hinder the intended processing steps. or even favored.

  • the assembled flat material is in particular a fiber material, in particular a paper or a cardboard.
  • the term “assembled” in this context means that the material is prepared, in particular cut, for the packaging element to be produced. If the packaging element to be produced is, for example, a bowl or a lid, then the manufactured material is preferably a blank that has (preferably exactly) the dimensions required to produce this bowl or lid. If necessary, individual prefabricated materials can also be connected to one another by a strand of the material of the prefabricated materials.
  • the manufactured materials may not be completely separated from the starting material, but only sections are cut out or perforations or weakenings are introduced into the starting material of the finished material, which prevent further processing of the starting material of the made-up material as endless material, because The mechanical stability necessary for processing as a continuous material is missing.
  • cardboard refers to a flat material that essentially consists of fibers (in particular fibers of plant origin). In particular, it is a material made from cellulose fibers. Such a material is preferably formed by dewatering a fiber suspension.
  • a “cardboard” has, in particular, increased mechanical strength compared to paper.
  • the "cardboard” preferably has a minimum weight per square meter of cardboard area of 130 g/m 2 [grams/square meter]; materials with a lower weight per area are often referred to as paper.

  • the connection between the manufactured material is preferably intensified or a different (possibly more permanent) connection technique is also developed for connecting the carrier material and the manufactured fiber material.
  • the composite created in subsequent processing steps is referred to here as the “second composite”.
  • the first composite and the second composite do not differ in that they consist of different materials.
  • the carrier material and the manufactured material are the same in the first composite and the second composite. Or in other words: the first group becomes the second group.

  • the result is a band consisting of the carrier material provided as an endless material and assembled materials, which are arranged one behind the other (preferably at uniform distances).
  • the method therefore preferably forms a continuous processing process in which the individual process steps for each individual packaging element to be produced are carried out one after the other but parallel to one another for packaging elements processed one behind the other/sequentially.

  • a provisional connection in the first composite can, for example, be designed as an adhesive bond.
  • the method described has advantages over other methods in relation to the transport system of the manufactured material, because certain materials cannot be processed from the roll as endless material, for example due to their properties. This applies, for example, to manufactured materials that have a relatively high rigidity and therefore cannot be provided on a roll. This can also apply, for example, because the assembled materials may already be formed with ribs and/or stiffening structures before step a) that prevent them from rolling up.
