A laundry or machine dishwashing dosage element, the laundry or machine dishwashing dosage element comprising first and second joined parts,
- wherein the first part comprises a water-soluble polymeric film substrate carrying one or more solid laundry or machine dishwashing substances,
- wherein the second part comprises a water-soluble polymeric film substrate carrying one or more further solid laundry or machine dishwashing substances,
- wherein the first part is joined to the second part in peripheral areas thereof so as to form a closed receptacle enclosing said solid laundry or machine dishwashing substances within it and so as to form at least one collapsed space between the solid laundry or machine dishwashing substances, and wherein the water-soluble polymeric film substrate of the first part comprises a plurality of mutually separated solid laundry or machine dishwashing substances arranged in side by side relation such that the plurality of substances carried by the first water-soluble polymeric film substrate and the further solid laundry or machine dishwashing substance or substances carried by the second water-soluble polymeric film substrate mesh or interdigitate within the receptacle.
A method of manufacturing a laundry or machine dishwashing dosage element, the method comprising:
- (a) forming a first part into a substrate comprising a water-soluble polymeric film carrying one or more solid laundry or machine dishwashing substances;
- (b) forming a second part into a substrate comprising a water-soluble polymeric film carrying one or more further solid laundry or machine dishwashing substances;
- wherein at least one of the substrate of the first part and the substrate of the second part carries more than one of the solid laundry or machine dishwashing substances and has at least one space between the solid laundry or machine dishwashing substances;
- and
- (c) joining the first part to the second part in peripheral areas thereof so as to form a closed receptacle enclosing the solid laundry or machine dishwashing substances within it and so as to collapse the at least one space between said substances.
