Definitions

  • the present invention relates to a method for producing an active substance sachet with at least one chamber, wherein at least one active substance preparation can be accommodated in each chamber.
  • the invention also relates to an active ingredient sachet produced in such a method and to the use of such an active ingredient sachet.
  • Products made from several layers of a nonwoven fabric are known from filter technology.
  • these products are bag-like, examples of which are vacuum cleaner bags or pocket filters. These are produced by connecting two or more layers of nonwoven fabric to one another over the entire surface or only in an edge area.
  • closed bags made of a nonwoven material are known in which an active ingredient preparation is contained, for example nonwoven bags which are filled with granules for dehumidifying or also tea bags.
  • the invention comprises a method for producing an active ingredient sachet with at least one chamber, wherein at least one active ingredient preparation can be accommodated in each chamber, comprising the following steps:
  • an active ingredient sachet comprising at least one chamber is produced according to the invention by initially providing a first material layer of a first material, for example a nonwoven or a nonwoven-like material, along a continuous production line, to which at least one active ingredient preparation is applied in a subsequent process step .
  • a second material layer made of a second material is applied to the first material layer, the previously applied at least one active ingredient preparation coming to lie between the first and the second material layer.
  • the second material of the second material layer can be identical to the first material of the first material layer, in particular the first and the second material layer can consist of a nonwoven or a nonwoven-like material.
  • the first material of the first material layer and the second material of the second material layer can also differ from one another.
  • the first material layer and the second material layer are connected to one another in sections, in such a way that an active ingredient sachet is formed with at least one chamber, with at least one active ingredient preparation being able to be accommodated in each chamber.
  • at least one active ingredient preparation can accordingly be accommodated in all of the designed chambers, but at least one active ingredient preparation can also be accommodated in only one or in individual chambers.
  • connecting seams are formed between the first and the second material layer, through which the active ingredient preparation cannot pass.
