Embodiment 1

[0172] The phosphate-containing powder composition (first substance) and assembly or "pellet" are provided in a complete compartment (Table 1 below) for use in an automatic dishwasher. The components are disc-shaped. The adhesive surface is flat. The ratio of the covered area (in this embodiment also the contact area) to the free area of ​​the lidding film is 12.5%. Set the vent as above.

Embodiment 2

[0177] The phosphate-containing powder composition (first substance) and assembly or "pellet" were provided in a complete compartment (Table 2 below) for use in an automatic dishwasher. Components are hemispherical. The adhesive surface is flat. The proportion of the covered area (in this embodiment also the contact area) relative to the free area of ​​the lidding film is 24%. Set the vent as above.

Embodiment 3

[0182] The citrate-containing powder composition (first substance) and assembly or "pellet" were provided in a complete compartment (Table 3 below) for use in an automatic dishwasher. The components are disc-shaped. The adhesive surface has a flat annular contact area around its circumference and a recessed area in which the component is not in contact with the lidding film. The ratio of the footprint of the module to the free area of ​​the lidding film is 25%. The ratio of the area of ​​the contact area of ​​the component, through which the adhesion is established, to the free area of ​​the lidding film was 14%. Set the vent as above.

Abstract

Dosage elements to be consumed in use in a ware washing machine are made by (a) forming a main container part within a cavity of a mould; (b) providing the main container part with a first substance; (c) adhering a second substance to the underside of a part which is to form a lid of the dosage element; and (d) sealing the lid-forming part to the main container part so as to close the main container part and enclose the first and second substances within it; wherein the second substance covers at least 5% of the free area of the lid-forming part.

Description

technical field [0001] The present invention relates to a dosage unit for an item washer and a method for its manufacture. Background technique [0002] Washing machines such as automatic washing machines and dishwashers typically utilize detergents and other additives in solid, liquid or powder form. These substances are either applied directly into the machine or dispensed via a system of trays or dedicated compartments to be added to the wash area at the start of the wash cycle or during the wash cycle. [0003] Typically, the desired detergent / additive is applied as a tablet comprising a mixture of active ingredients. These active ingredients may remain separate due to incompatibility. Alternatively or in addition, these active ingredients can be kept separate, whereby they are activated at different points in the wash cycle or rinse cycle. Activation at a specific point in time can be achieved by including a time- and / or temperature-dependent release unit in the subs...
