Claim Text:
1. A method of producing a dosage form detergent product, comprising the sequence of: (i) producing an open-mouthed pouch by forming a water-soluble, synthetic plastics film into a mould cavity defining said pouch, (ii) introducing a particulate first detergent composition into the pouch, (iii) forming a recess in the upper surface of the particulate first detergent composition, said forming being effected by a punch tool having a protuberance and a surrounding area for compacting the first detergent composition, (iv) introducing into said recess an insert consisting of a pre-formed, shape-retaining second compressed particulate detergent component with an at least substantially planar face positioned to be exposed from the particulate first detergent component, said second, pre-formed detergent component being in contact with the first detergent component, and (v) positioning a water-soluble film over the insert and sealing the water-soluble film over the mouth of the pouch and against said exposed face of the pre-formed detergent product, wherein any compaction pressure used in production of the product is insufficiently high so that the particulate first detergent composition is compacted to a mass which would not be shape-retaining if the water soluble film of the product were to be removed, and wherein the at least substantially planar surface is urged relatively into contact with the sealing film.
