Definitions

  • This application has a method for producing coated laundry or cleaning agent portions and washing or cleaning agent sachets, comprising a plurality of washing or cleaning agent portions, the subject of the subject.
  • Detergent or detergent portions include, for example, detergent tablets for washing textiles, automatic dishwashing detergent tablets or hard surface cleaning agents, bleach tablets for use in dishwashers or dishwashers, water softening tablets or patch salt tablets.
  • Detergent tablets or detergent tablets are widely described in the prior art and are becoming increasingly popular with consumers because of their simple dosage. Tableted detergents or cleaners have a number of advantages over powdered ones: they are easier to dose and to handle and, due to their compact structure, have advantages in storage and transport. Also in the patent literature washing detergent or detergent tablets are thus described comprehensively. A problem which occurs again and again in the application of washing or cleaning active moldings is the too low disintegration and dissolution rate of the moldings under conditions of use.
  • washing or cleaning tablets on the market are that they still have to be provided with an outer packaging which protects the ingredients from environmental influences (in particular moisture).
  • These "flow packs" of water-insoluble materials must be removed by the consumer before dosing, which can be troublesome for the consumer and cause waste.
  • Possible solutions to this problem are the coating of the molding with water-soluble polymers or the use of water-soluble packaging.
  • a coating provides visually appealing tablets with a smooth, glossy surface and advantageous haptic properties.
  • the coating of tablets is technically complicated and expensive.
  • the use of water-soluble packaging is described in the form of bags of water-soluble film in the prior art.
  • tablets packaged in this way can no longer be metered in via the dispensing chamber, since the water-soluble material prevents the access of water to the tablet and thus the disintegration of the shaped body too long, so that the dispensing process is ended and the tablet remains unresolved in the dispensing chamber or at least larger Caused residues.
  • European Patent EP 888 448 B1 discloses a detergent concentrate for the preparation of ready-to-use aqueous detergent solutions in detergent storage tanks of cleaning machines, in particular high-pressure cleaners, spray extraction devices or the like, comprising a gas-releasing component in contact with water, the detergent concentrate being packaged in portions in a water-soluble wrapper, such that the wrapper is in close contact with the detergent concentrate, but the wrapper is different from a coating applied to the detergent concentrate.
  • the gas-splitting effervescent system causes, as soon as the cleaning concentrate located inside the enclosure comes into contact with water, ie when the first leak in the enclosure is formed, gas is released, which inflates the enclosure and eventually blows it up, while the cleaning agent concentrate completely surrounding water.
