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.
• the arrangement of a second container is particularly advantageous if in the separate containers preparations are stored, which are usually not stable to each other, such as bleaching agents and enzymes.
• a second Dosing provided with a Dosierhunteinlauf and a Dosierhuntauslauf, wherein the Dosierhunteinlauf and the Dosierhuntauslauf the second metering chamber are arranged such that a gravitational product supply from the second container into the metering chamber and a gravitational product release is effected from the metering chamber in the use position of the dispensing system.

• more than two containers are provided in the dispensing and metering system.
• metering chambers may also be advantageous to mold the metering chambers in one piece with the container, whereby a cost-effective production of container and metering chamber is achieved by an integral manufacturing step.
• a simple and variable setting of different metering ratios between the different preparations is desired.
• one or more containers each have a liquid-tight sealable container opening. Through this container opening, it is possible, for example, to refill stored in this container product.
• control unit may also be releasably connected to one or more of the containers.
