Definitions

  • the invention relates to a mobile dispensing and dosing system for the temperature-related release of flowable or spreadable preparations, in particular preparations containing detergents or cleaning agents, in dishwashers, washing machines, dryers or the like.
  • the precise and appropriate dosage of active substances is relevant for a variety of applications.
  • the dosage of active substances is of increasing importance, which is primarily based on the exact and demand-controlled dosage of the corresponding active ingredients, which on the one hand protects the environment by conserving resources and avoidance of over- and overdoses, on the other hand, the efficiency of the drugs so dosed is optimized.
  • Detergents for dishwashers are often used today in the form of detergent 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. It is therefore regularly desirable to provide a metering device with the simplest possible mechanical configuration.
  • 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.
  • the object of the invention is therefore to overcome the disadvantages known from the prior art and to provide a dispensing and metering device which realizes the release of a defined metered amount of a flowable or spreadable product at a predefined temperature in a simple, purely mechanical manner.
  • Movable in the sense of this application means that the dispensing and dosing system is not permanently connected to a device such as a dishwasher, washing machine, laundry dryer or the like, but can be removed, for example, from a dishwasher or positioned in a dishwasher.
  • At least one second container is provided for receiving at least one second flowable product, the second container having at least one outlet opening arranged to effect gravity release of product from the second container in the dispensing system use position is.
