S-shaped detergent laminate

Claim 2

An article for delivering a cleaning composition to a wash water comprising; (i) a flexible substrate folded into a unitary S-shaped construction, said construction including three substrate areas each lying in substantially parallel planes one above another; (ii) a detergent composition comprising an effective amount for cleaning fabrics of a surfactant and a builder, said composition being spread in a region between a first and second of said substrate areas and having an adhesive strength sufficient to bind said first and second areas together, and at least one edge length of said first area not being bonded, other than through said detergent composition, to an adjacent edge length of said second area thereby allowing egress of said composition into said wash water, and said substrate separating into but a single sheet upon exhaustion of detergent composition therefrom; and (iii) a further composition for cleaning fabrics which is spread in a region between said second area and a third adjacent one of said substrate areas and having an adhesive strength sufficient to bind said second and third area together, and at least one edge length of said second area not being bonded, other than through said further composition, to an adjacent edge length of said third area and thereby allowing egress of said further composition into said wash water, said further composition comprising a component selected from the group consisting of bleaches, bleach precursors, enzymes, fabric softeners and mixtures thereof.

Claim 3

An article according to claim 1 wherein said detergent comprises a surfactant selected from the group consisting of nonionic, anionic, cationic, zwitterionic, amphoteric surfactants and mixtures thereof.

Claim 4

An article according to claim 1 wherein the weight ratio of detergent composition to the total folded substrate ranges from 20:1 to 1:20.

Claim 5

An article according to claim 1 wherein the weight ratio of detergent composition to the total folded substrate ranges from 8:1 to 1:8.

Claim 6

An article according to claim 1 wherein said substrate is formed from a natural or synthetic fiber selected from the group consisting of paper, woven cloth and non-woven cloth.

Claim 7

An article according to claim 1 wherein said substrate is a non-woven material selected from the group consisting of rayon, polyester, polypropylene, polyethylene and mixtures thereof.

Claim 8

An article according to claim 1 wherein said builder is a polycarboxylate material selected from the group consisting of polyacrylate, acrylic/maleic acid derived copolymer, and mixtures thereof.

Claim 9

An article according to claim 1 wherein said further composition comprises a bleach.

Claim 10

An article according to claim 8 wherein said bleach is an inorganic peroxygen compound selected from the group consisting of sodium perborate monohydrate, sodium perborate tetrahydrate, sodium percarbonate and potassium monopersulfate.

Claim 11

An article according to claim 8 wherein said bleach is an organic peroxygen acid selected from the group consisting of 1,12-diperoxydodecanedioic acid and peroxy succinic acid.

Claim 12

An article according to claim 1 wherein the bleach precursor is selected from the group consisting of tetraacetyl ethylenediamine, sodium benzoyloxybenzene sulfonate, sodium nonoyloxybenzene sulfonate and 2-(N,N,N-trialkylammonium)alkyl sulfophenyl carbonate salt.

Claim 13

An article according to claim 1 wherein said enzyme is selected from the group consisting of proteases, amylases, lipases, cellulases and mixtures thereof.

Claim 14

An article according to claim 1 wherein said fabric softener is a quaternary ammonium salt.

Claim 15

An article according to claim 13 wherein said quaternary ammonium salt is a ditallowdimethyl ammonium salt.

Claim 16

An article for delivering a cleaning composition to a wash water comprising; (i) a flexible substrate folded into a unitary S-shaped construction, said construction including three substrate areas each lying in substantially parallel planes one above another; (ii) a detergent composition comprising an effective amount for cleaning fabrics of a surfactant and a builder, said composition being spread in a region between a first and second of said substrate areas and having an adhesive strength sufficient to bind said first and second areas together, and at least one edge length of said first area not being bonded, other than through said detergent composition, to an adjacent edge length of said second area thereby allowing egress of said composition into said wash water, and said substrate separating into but a single sheet upon exhaustion of detergent composition therefrom; and (iii) a further composition for cleaning fabrics which is spread in a region between said second area and a third adjacent one of said substrate areas and having an adhesive strength sufficient to bind said second and third area together, and at least one edge length of said second area not being bonded, other than through said further composition, to an adjacent edge length of said third area and thereby allowing egress of said further composition into said wash water, said further composition comprising a component selected from the group consisting of sodium perborate monohydrate, sodium perborate tetrahydrate, sodium percarbonate, sodium monopersulphate, 1,12-diperoxydodecanedioic acid, peroxysuccinic acid, sodium dichloroisocyanurate, tetraacetyl ethylenediamine, sodium benzoyloxybenzene sulfonate, sodium nonoyloxybenzene sulfonate and 2-(N,N,N-trialkylammonium)alkyl sulfophenyl carbonate salt.

Claim 17

An article for delivering a cleaning composition to a wash water comprising; (i) a flexible substrate folded into a unitary S-shaped construction, said construction including three substrate areas each lying in substantially parallel planes one above another; (ii) a detergent composition comprising an effective amount for cleaning fabrics of a surfactant and a builder, said composition being spread in a region between a first and second of said substrate areas and having an adhesive strength sufficient to bind said first and second areas together, and at least one edge length of said first area not being bonded, other than through said detergent composition, to an adjacent edge length of said second area thereby allowing egress of said composition into said wash water, and said substrate separating into but a single sheet upon exhaustion of detergent composition therefrom; and (iii) a further composition for cleaning fabrics which is spread in a region between said second area and a third adjacent one of said substrate areas and having an adhesive strength sufficient to bind said second and third area together, and at least one edge length of said second area not being bonded, other than through said further composition, to an adjacent edge length of said third area and thereby allowing egress of said further composition into said wash water, said further composition comprising a component selected from the group consisting of sodium perborate monohydrate, sodium perborate tetrahydrate, sodium percarbonate, sodium monopersulphate, 1,12-diperoxydodecanedioic acid, peroxysuccinic acid, sodium dichloroisocyanurate, tetraacetyl ethylenediamine, sodium benzoyloxybenzene sulfonate, sodium nonoyloxybenzene sulfonate and 2-(N,N,N-trialkylammonium)alkyl sulfophenyl carbonate salt.
