1. A method of using a dosing apparatus to dose a liquid product for use in a washing machine or dishwasher, comprising:
- calculating a maximum filled weight of a vessel when it is filled to a maximum filling volume with the liquid product optionally together with one or more other substances;
optionally feeding a preset amount of the one or more other substances into the vessel;
feeding the liquid product into the vessel during a dosing cycle;
continuously determining a weight of the vessel during the dosing cycle;
monitoring the determined weight of the vessel to determine when the maximum filled weight of the vessel corresponding to the maximum filling volume of the vessel has been reached and thereupon halting the feeding of the liquid product;
determining a feeding time required to feed the liquid product into the vessel until the maximum filled weight of the vessel is reached;
discharging the liquid product and the optional one or more other substances from the vessel to the washing machine or dishwasher; and
if the desired amount of liquid product exceeds the maximum filled weight of the vessel such that desired amount of liquid product corresponds to a larger volume than is made available by the maximum filling volume of the vessel, feeding a remaining amount of liquid product into the vessel based on the feeding time until the desired amount of the liquid product is reached.

Abstract
The present invention provides methods for the multiple dosage of one or more liquid products or both liquid and solid products wherein the dosing amount of at least one liquid product is measured by a weight cell. Moreover, dosing apparatus and dosing systems for applying those methods are provided. Additionally, the present invention refers to a method for washing textiles comprising a dosing step in which at least one of the inventive dosing methods, and/or at least one of the inventive dosing apparatus or dosing systems, respectively, are used.

11. A method for dosing a liquid product for use in a washing machine or dishwasher, the method comprising:
-
transmitting a starting signal from the washing machine or dishwasher to a programmable logic control so as to start a dosing; feeding the liquid product into a vessel during a first step of the dosing cycle; continuously determining a weight of the vessel during the first step of the dosing cycle using a weighing device; continuously transmitting the determined weight to the programmable logic control; halting the feeding of the liquid product into the vessel when the weight of the vessel reaches a maximum filled weight of the vessel corresponding to the maximum filling volume of the vessel; measuring a feeding time required to feed the liquid product into the vessel until the weight of the vessel reaches the maximum filled weight of the vessel; discharging the liquid product from the vessel directly or indirectly into the washing machine or dishwasher; and if a desired amount of liquid product exceeds the maximum filled weight of the vessel such that desired amount of liquid product corresponds to a larger volume than is made available by the maximum filling volume of the vessel, feeding a remaining amount of liquid product into the vessel during one or more subsequent steps of the dosing cycle based on the feeding time until the desired amount of the liquid product is reached. - View Dependent Claims (12, 13, 14, 15)

16. A method of using a dosing apparatus for dosing a liquid product for use in a washing machine or dishwasher, the method comprising:
-
starting a dosing cycle; feeding the liquid product into a vessel during a dosing cycle; determining a weight of the vessel during the dosing cycle using a weighing device; monitoring the weight of the vessel to determine when a maximum filled weight of the vessel corresponding to the maximum filling volume of the vessel has been reached, and halting the feeding of the liquid product into the vessel when the weight of the vessel corresponds to the maximum filled weight; measuring a feeding time required to feed the liquid product until the maximum filled weight is reached; discharging the liquid product from the vessel to the washing machine or dishwasher; and if the desired amount of the liquid product exceeds the maximum filled weight of the vessel such that desired amount of liquid product corresponds to a larger volume than is made available by the maximum filling volume of the vessel, feeding a remaining amount of the liquid product into the vessel based on the feeding time until the desired amount of the liquid product is reached. - View Dependent Claims (17, 18, 19)
