Abstract: This invention relates to a dosage element of cleaning composition and an associated chamber for use in a ware washing machine, for example a dishwashing machine or a laundry washing machine. The dosage element and chamber are particularly useful in the context of forming part of a multi-dosing detergent delivery device and/or a refill for such a device. The element supports various different configurations of ingress and egress holes for an efficient dissolution of cleaning composition.

Abstract: A liquid detergent composition has a thickening system which comprises; (a) a carboxylic acid/carboxylate polymer, and (b) a polymer comprising an ammonium group.

Abstract: A method of forming an essentially tubular blowable plastics parison comprises injection moulding an essentially tubular parison around a mould surface. Means for injecting flowable plastics material to said injection mould at an injection station to form a parison within said mould surface are used. These comprise a plurality of individual injectors, with at least a secondary injector being capable of injecting a different composition from the remaining primary injectors.

Abstract: An article comprises a rack of solid sticks (12) of dishwasher detergent, retained on a backing material (16) and being formable into a nested, preferably cylindrical, form. The nested article is inserted into a holder, which is a plastics body, rigid and substantial. The holder is a permanent article located in use in a dishwasher but the article is a refill. Wastage of material when it is exhausted is minimal.

Abstract: The invention relates to a multi-dosing detergent delivery device. In embodiments of the present invention, the device comprises a housing (2) for receiving a cartridge (200). The cartridge (200) has a plurality X of chambers, each accommodating a detergent composition. The device has a lid (3,1100) for receiving water/wash liquor and directing it selectively into a chamber of the cartridge (200) to contact the detergent composition therein and an outlet to allow the detergent loaded wash liquor to exit the device. The device has automatic indexing means (100) for automatic movement of said cartridge (200) relative to said lid (3,1100) so as to cause a neighboring chamber to be in an exposed, ready to be used, position prior to a next washing cycle and features an end stop mechanism (A,B) for preventing actuation of said automatic indexing mechanism (100) subsequent to an Xth washing cycle.

Abstract: A container adapted to contain and dispense a product. Said container comprises a hollow body, a filling opening, a dispensing opening, a valve and a flexible and resilient support means for said valve. Said flexible and resilient support means urges said valve against said dispensing opening, achieving a leak-tight engagement between said valve and said dispensing opening. Said flexible and resilient support means can be resiliently deformed by an external force acting on said valve whereby said leak-tight engagement between said valve and said dispensing opening is disengaged, allowing said contained product to be spread by said valve. Said flexible and resilient support means comprises a housing which fits the container and defines said dispensing opening at one extremity. Said housing comprising a resiliently deformable means urging said valve against said dispensing opening to achieve said leak-tight engagement.

Abstract: The use of an emanator blister, comprising a nonwater soluble membrane, for the release of a surfactant. Also an emanator blister, the emanator comprises a non-water soluble membrane which is suitable for the dispense of a surfactant.

Abstract: A liquid hard surface detergent composition comprising a liquid mixed alkoxylate fatty alcohol non-ionic surfactant comprising a greater number of the lower higher alkoxylate group than the higher alkoxylate group in the molecule and a builder. The compositions provide good shine/anti-spotting characteristics on hard surfaces and are especially suitable for use as automatic dishwashing compositions.

Abstract: A process for producing a container comprising at least one aperture, the process comprising the steps of: a) thermoforming a material to produce an intermediate container in a mould, b) supporting at least a portion of the intermediate container with a supporting means, c) securing the intermediate container to hold it in a fixed locus in contact with the supporting means, d) forming at least one aperture in a surface of the intermediate container in an area of the intermediate container adjacent to the portion of the intermediate container supported by the supporting means to produce the container, and wherein the supporting means provides sufficient support to the intermediate container to prevent substantial deformation thereof during at step (d). A container produced by the method is also provided.

Abstract: The invention relates to a multi-dosing detergent delivery device.

Abstract: A particulate material comprising a crystalline polycarboxylate wherein the particles of the material have a coating. A solid detergent composition comprising a crystalline polycarboxylate containing particulate material of the invention is also provided. The particulate material of the invention exhibits good building/chelancy properties and is especially suitable for use in detergent tablets.

Abstract: A detergent dispensing device for an automatic washing machine has a cartridge, a selecting mechanism, an operating mechanism, and a thermal element. The cartridge includes a plurality of chambers to accommodate a detergent composition. The selecting mechanism selectively exposes each chamber to wash liquor allowing the detergent, in use, to be washed out of the chamber. The operating mechanism is movable from a first position to a second position for loading mechanical energy into the device which provides a restoring force for the operating mechanism. The thermal element retains the operating means in the second position and is arranged to move when subjected to an elevated temperature prevailing in an interior of the washing machine during a wash cycle, thereby the thermal element moves or releases the operating mechanism. The operating mechanism is arranged to advance the selecting mechanism to an adjacent chamber as the cartridge remains stationary.

Abstract: A process for the manufacture of a detergent tablet comprises filling a recess in a first pre-formed body with a gel; adding a second body to the gel; and allowing/causing the gel to solidify.

Abstract: A detergent composition comprising; a subtilisin variant having the amino acid sequence set forth in SEQ ID NO 1, and at least one additional ingredient selected from; i) bleaches selected from percarbonates, persulphates and organic peracids, ii) aminocarboxylates, or iii) sulphonated polymers, or iv) organophosphoric acids or salts thereof and mixtures thereof is provided. Also provided is a detergent composition comprising a subtilisin variant having the amino acid sequence set forth in SEQ ID NO 1, wherein, the detergent composition is at least partially enveloped in a water soluble or water dispersible package. The compositions exhibit good performance on proteinaceous stains, even when formulated at alkaline pHs. A method of removing proteinaceous stains from surfaces comprising such stains is also provided.
