Definitions

  • the invention relates to a metering bag, with which a pourable product, in particular a liquid can be metered by a user as needed.
  • the present invention is concretely of a Dosierhuntnitrosine extracting from the EP 2 315 703 B1 out.
  • the generic Dosierhuntnitrosine therefore comprises a front wall and a rear wall, which are connected to a first side edge, a second side edge, a lower edge of the bag and an upper edge of the bag together.
  • the dosing chamber bag further has a partition wall, which is attached to an inner side of the bag on the front wall and the rear wall and extending in a bag transverse direction sealingly to the two side edges, to a bag interior in the direction of the lower edge of the bag into a Reservoirsch and to separate in the direction of the upper edge of the bag in a metering chamber, wherein the partition has a crease line, two wings extending away from the crease line and a passage opening as a single connection between the reservoir chamber and the metering chamber and wherein the metering chamber is adapted for a Browntddling.
  • the lower edge of the bag may also be referred to as a bag bottom and the upper edge of the bag as a bag head.
  • the two front walls can either adjoin one another directly at the lower edge of the bag and can preferably be connected by a sealed seam or by a separate bottom section, which also forms a floor.
  • the according to the EP 2 315 703 B1 V-shaped separating tape forms a kind of receiving trough or a basin for the product to be dosed.
  • the filling material in particular a liquid
  • the passage opening arranged in a wing into the reservoir chamber. If the Dosierhunt bass is then turned back so that the metering chamber is located above the reservoir chamber or if the pressure on the metering falls away, the filling level in the metering chamber, ie the amount of liquid to be metered, determined by the position of the passage opening. If the dosing chamber bag is being held or set up, excess contents present in the reservoir chamber, which is located above the passage opening, are directed back into the reservoir chamber. The storage height up to the passage then determines the volume provided for the dosage.
  • the volume to be dispensed can also be varied. For example, by tilting the bag contents from the Dosing chamber passed to the passage opening and thus transferred into the reservoir chamber. Even by a slight compression of the reservoir chamber, the volume to be dosed can be selectively reduced by a user.
  • the known configuration of the dosing chamber bag is still in need of improvement. Especially with a rotation through 180 °, the back pressure of the filling material can lead to an unwanted folding of the partition. There is then the danger that the passage opening is closed or at least the transfer from the reservoir chamber into the dosing chamber is made more difficult. Furthermore, even with a transparent embodiment of the front wall and the rear wall, the exact filling height in the region of the V-shaped partition is not always easy to recognize.
  • the present invention has the object to improve the handling of a generic Dosierhunt files.
  • the crease line is facing the upper edge of the bag such that the wings wegersharen from the bending line in the direction of the lower edge of the bag.
  • the crease line faces the upper edge of the bag and the wings extend away from the crease line in the direction of the lower edge of the bag, two receiving spaces are formed for metering the contents within the metering chamber, which adjoin the front wall and the rear wall, respectively.
  • the filling level within the metering chamber can thus be very well recognized by a user, even if the front wall or rear wall usually formed from a bag film has a certain turbidity or coloration.
  • the front wall and the rear wall are at least partially - for example, by an imprint - opaque and a transparent window in the region of the partition on the front wall and / or the rear wall is provided. Since, in the context of the invention, the front wall and the rear wall can be formed at least partially opaque, overall a better appearance can also be achieved.
  • the front wall and the rear wall may be provided, for example, with a decor, manufacturer information and product information.
  • the reservoir chamber and the metering chamber are separated from the partition wall as a membrane in such a way that the passage opening as the only connection between the reservoir chamber and the metering chamber is provided.
  • the partition wall is then sealingly brought up to the two side edges.
  • the front wall and the rear wall are connected to each other at the side edges by longitudinal sealing seams, wherein the ends of the partition are also integrated into the longitudinal sealing seams to achieve a tight seal there.
  • the partition expediently ends in the longitudinal sealing seam. This means that the front wall and the rear wall have a slightly greater width in the transverse direction of the bag than the dividing wall. This ensures that the longitudinal sealing seams on the one hand tightly integrate the partition and on the other hand securely close the bag at its edge.
  • the front wall and the rear wall may be formed from a known, preferably multi-layered bag film.
  • bag films which have a sealing layer on one side and an outer or cover layer on the other side are suitable.
  • a sealing layer of polyethylene can be arranged on the inside of the bag, while a cover layer of polyethylene terephthalate forms the outside of the metering chamber bag.
  • a bag film is a standard material, which on the one hand is inexpensive and on the other hand ensures sufficient stability.
  • the thickness of the sealing layer may be, for example, between 40 .mu.m and 200 .mu.m, while a significantly smaller thickness of, for example, between 5 .mu.m and 20 .mu.m is provided especially in the case of an outer layer of polyethylene terephthalate.
  • a typical construction which is also suitable within the scope of the invention is, for example, 100 ⁇ m PE / 12 ⁇ m PET.
  • the dividing wall is usually initially placed on the front wall or the rear wall or a foil section of the bag foil forming the front wall or the rear wall, the sealing sealing of the dividing wall subsequently taking place.
  • a multilayer film is also provided for the partition according to a preferred embodiment of the invention, which is attached to the wings with a sealing layer by sealing seams on the front wall or the rear wall, wherein the sealing layer in comparison to an opposite outer layer of the multilayer film has a smaller Has melting temperature.
  • a construction PE / PET is also suitable for the partition.
  • the partition can thus also be formed from the same bag film, which is also provided for the front wall and the rear wall.
  • an overall thinner sheet material is used, which indeed ensures the membrane function, but has a better mobility.
  • the stability of the partition without or of secondary importance for the handling and leakage protection of Dosierhunt files.
  • some stability of the partition wall is necessary in view of handling during the manufacturing process and avoidance of uncontrolled buckling during use. Accordingly, a thinnest but still stiff design is preferred.

  • the passage opening is then in the context of such a configuration expediently offset from the middle of the upper edge of the bag in the direction of the second side edge, in particular immediately adjacent to the second side edge.
  • the wings are designed rectangular. Accurate metering is then made more difficult than the previously described embodiment, but with regard to manufacture, the arrangement and sealing of a partition with rectangular blades may be easier.
  • the rectangular wings may be connected via at least a part of their transverse width in the bag transverse direction by a connecting seam with the respective adjacent front wall or rear wall, wherein the connecting seam in a plan view of the front wall in the direction of the second margin increases.
  • the metering chamber bag according to the invention can be produced in various ways, wherein the dividing wall is expediently placed on a section during the production process, which subsequently forms the front wall or rear wall.
