Definitions

  • the invention relates to a stand-up pouch made of a heat-sealable or weldable plastic film for receiving liquid and / or pasty media with a removal opening, which has two side walls which form essentially rectangular surface parts which are sealed to one another on their longitudinal edges, with between a foldable film element, which is inserted between the side walls and serves as a standing base, and in the area of the upper end of the side walls a foldable film element which is inserted between the side walls and forms a ceiling part.
  • Stand-up pouches made of plastic films are known in particular as disposable packaging for beverages, usually they are tapered packagings with a filling volume of 0.2 l.
  • the used foils of such beverage packaging have a thin alurainium film layer, which stabilizes the packaging, among other things.
  • a base is incorporated into the underside, so that the bag can be placed on a base even after it has been opened, without the contents of the bag running out of the removal opening or the bag tipping over.
  • the removal opening can be predetermined by a target puncture opening through which a straw tapering to the end can be pierced.
  • foil bags In addition to beverages, liquid or pasty media, for example liquid detergents, are filled into foil bags. Such foil bags are primarily used as tachy-fill packs.
  • stand-up pouches In order to achieve increased stability of such stand-up pouches with a lower base part which is inserted between the side walls, such stand-up pouches preferably consisting of two Vand parts welded to one another, an additional cover part is built in, which is constructed similarly to the stand base .
  • a fundamental advantage of the film bags can be seen in the fact that they can be folded up very flat in the unfilled state and thus take up little space.
  • Stand-up pouches with a larger volume, ie with a volume of up to two liters are practically not used for fillings which are removed in portions, since an opened pouch, for example by cutting off an upper corner edge, does not sufficiently guarantee that when Penetration of air into the interior and sufficient stability remains after a partial removal of the contents.
  • the object of the invention is to provide a stand-up pouch which has sufficient stability even when the contents are partially removed, the contents of which can be removed in portions, which is easy to handle and transport, which is easy to manufacture and in the unfilled state can be stored in a space-saving manner.
  • the removal opening is formed by a closable removal nozzle which has a flange at one end with which it is fastened in the upper region of one of the side walls.
  • the contents of the stand-up pouch can be removed in portions through the closable removal nozzle.
  • the removal nozzle is located in the upper region of the side walls, so that the stand-up pouch can also be set up on its stand base without the contents of the stand-up pouch being able to escape from the opened removal stub. It is essential here that the stand-up pouch has a stable shape, which is given in particular by the fact that the stand-up pouch has an additional cover part which corresponds approximately to the bottom part.
