  • Dishwashing detergents are often used today in the form of dishwashing tablets. Although the application and dosage for the user is relatively simple and convenient, the drug release from the tablets is not optimized in terms of rinsing and drying cycles of the respective dishwasher.
  • Dosing devices for dispensing cleaning agents during the washing cycles of a dishwasher are known, for example, from WO2006 / 021764.
  • the dispensing of cleaning agents is controlled by a bimetal that triggers a spring mechanism upon reaching a predetermined temperature, which causes the release of cleaning agents in the dishwasher.
  • a major disadvantage of this metering device is its complex mechanical structure, whereby the cost of their production are high. Furthermore, the release mechanism can only be triggered by exceeding or falling below defined temperatures in the dishwasher. One way to use other parameters to trigger the release of detergent does not exist here.
  • the device known from WO2006 / 021764 is not suitable for liberating liquid or gelatinous preparations. However, this would be particularly advantageous, since higher concentrations of active compound than in solid dosage forms such as powders or tablets can usually be realized in liquids or gels.
  • detergents are usually metered into the laundry-filled drum via a metering drawer of the washing machine.
  • the dosing is done by rinsing the dosing drawer with water, whereby the detergent is dissolved or entrained and fed into the laundry drum.

  • metering balls are known for metering detergents which can be filled with a defined amount of detergent and are added directly into the washing drum with the laundry to be cleaned. Again, there is the disadvantage that a controlled release of detergent does not occur.

  • the flow conditions may vary greatly depending on the type of toilet and the positioning of the toilet bowl in or on the toilet bowl. So it may happen, for example, that in some types of toilet no drug release from the toilet rinse takes place because the toilet bowl is not or not sufficiently covered with water during flushing and thus the dosing of the toilet rinser is not triggered.
  • Toilet manufacturer provided water supply, whereby the flushing power of a toilet can be significantly reduced.
  • the dosing devices described in some cases have large volumes, which is often perceived as disadvantageous for aesthetic reasons and also often presents problems from a functional point of view since, for example, the usable space in a dishwasher or in a toilet bowl is reduced.
