  • the present invention relates to a detergent portion unit according to claim 1 with at least one receiving chamber filled with a solid detergent or cleaning agent, which is formed by a water-soluble casing that comprises a water-soluble nonwoven fabric.
  • the application also relates to a method for producing this detergent portion unit and washing methods for textiles using such a detergent portion unit.
  • detergents and cleaning agents are subject to constantly changing requirements. For some time now, the main focus has been on the convenient dosing of detergents and cleaning agents by the consumer and the simplification of the work steps required to carry out a washing or cleaning process.
  • Pre-portioned detergents or cleaning agents offer a technical solution, for example water-soluble containers with one or more receiving chambers for solid or liquid detergents or cleaning agents.
  • EN 60301823T2 discloses a water-soluble bag containing a detergent composition having adequate dissolution properties and allowing migration of gaseous substances from the bag without the need for puncturing the bag.
  • water-soluble polymers are usually formed into receiving chambers, which are then filled with a washing or cleaning agent and finally sealed.
  • the receiving chambers can be made from water-soluble polymer films (foils) using a deep-drawing process, for example.
  • a water-soluble polymer is formed into a receiving container using injection molding.
  • Both solid and liquid detergents or cleaning agents are suitable for filling the water-soluble containers. If solid detergents or cleaning agents are used and these contain gas-releasing components such as bleach, the sealed water-soluble container has perforations to prevent excessive pressure build-up, which enable gas exchange between the interior of the receiving chamber and the environment.
  • the implementation of corresponding perforations requires an additional process step in the manufacture of the water-soluble packaging materials or in the manufacture of the filled detergent dosing units.
  • the filled detergent portion units are generally hygroscopic due to the water-soluble packaging material used to manufacture them.
  • the tendency and ability of the packaging to absorb water can, during manufacture, packaging, storage and subsequent use by the consumer, lead to portion units sticking to the surfaces of machines or packaging and not being able to be conveyed optimally, or to adjacent portion units sticking together, for example in a common outer packaging.
  • To avoid this tendency of the water-soluble portion units to stick it is possible to To modify surface properties by applying a powdering agent.
  • the powdering of the water-soluble detergent portion units requires an additional process step.
  • the washing performance provided by the detergent portion unit is directly related to the dissolution properties of the portion unit.
  • reducing the thickness of the surrounding film material simultaneously results in reduced mechanical stability of the portion units.
  • the application was based on the object of providing water-soluble detergent portion units which can be produced by means of simplified processes, have a high product and storage stability, can be easily assembled using minimal amounts of additional packaging material such as stand-up pouches or cardboard boxes and delight the consumer with an appealing olfactory, visual and haptic quality.

  • the side walls of the receiving chambers are preferably planar. Spatially opposite side walls can be arranged both parallel and not parallel to one another.
  • the base area of the receiving chambers can be convex, concave or planar, whereby planar base areas are preferred in view of the later filling of the space(s) between the receiving chambers.
  • the base area itself can be designed as a circle, but can also have corners.
  • Base areas with one corner two, three, four, five, six, seven, eight, nine, ten, eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen, twenty or more corners are preferred within the scope of the present application.

  • Foams can also be used as granulation agents.

  • Melt solidification is generally particularly suitable for shaping low-melting substances that are stable in the melting temperature range (e.g. urea, ammonium nitrate and various formulations such as enzyme concentrates, pharmaceuticals, etc.); the corresponding granules are also known as prills.
  • Spray drying is used in particular for the production of detergents or detergent components.

For this reason, the execution of such a seam increases the disintegration speed of the detergent portion unit and ensures residue-free dissolution even at low washing temperatures.
  • a group of preferred detergent portion units has at least one receiving chamber.
