Definitions
- the present invention relates to a detergent portion unit, comprising a gel body and a rigid enveloping substance at least partially covering the gel body.
- the application also relates to a method for producing this detergent portion unit and a washing method for textiles or crockery using such a detergent portion unit.
- water-soluble polymers are generally formed into receiving chambers, which are then filled with a detergent or cleaning agent and finally sealed.
- the receiving chambers can be made, for example, from water-soluble polymer films by deep-drawing processes.
- a water-soluble polymer is injection molded into a receptacle.
- the water-soluble packaging material used to package the filled detergent portion units is generally hygroscopic.
- the tendency and ability of the packaging to absorb water can result in portion units adhering to the surfaces of machines or packaging materials and being unable to be optimally conveyed, or in adjacent portion units, for example in a common outer packaging, glue together.
- the powdering of the water-soluble detergent portion units in turn requires an additional process step.
- the washing performance provided by the detergent portion unit is directly related to the dissolving properties of the portion unit.
- the reduction in the thickness of the surrounding film material results in reduced mechanical stability of the portion units.
- Detergent tablets offer an alternative to the sachets described above, in which however adequate mechanical stability and high dissolution rate are incompatible in a similar way as in the case of sachets.
- the application was based on the object of providing detergent portion units that can be produced using simplified processes, have high product and storage stability, can be made up easily using very small amounts of packaging materials and are an appealing olfactory, visual and/or haptic appeal.
- the detergent portion units should have a high product performance and be easy and safe to handle for the consumer.

- the detergent portion unit according to the invention comprises a dimensionally stable gel and a specific coating substance which at least partially covers this gel.
- Gel bodies are bodies that exhibit elastic deformation behavior under the action of force.

- a “molding” is a single body that is self-stabilizing in its imposed shape.
