## Abstract

A water-soluble pouch suitable for use in machine dishwashing and which comprises a plurality of compartments in generally superposed or superposable relationship, each containing one or more detergent active or auxiliary components, and wherein the pouch has a volume of from about 5 to about 70 ml and a longitudinal/transverse aspect ratio in the range from about 2:1 to about 1:8, preferably from about 1:1 to about 1:4. The water-soluble pouch allows for optimum delivery of dishwashing detergent. A process for the manufacture of multi-compartment pouches and a pack to contain the pouches are also disclosed.

## Claims

### Claim 1

A unit dose machine dishwashing article comprising a water-soluble pouch containing a detergent composition, wherein the water-soluble pouch comprises upper and lower generally opposing outer walls and one or more internal partitioning walls, each of the walls comprising a water-soluble material, the walls forming first and second compartments, wherein the first and second compartments each comprise a portion of the detergent composition, wherein the detergent composition disposed in the first compartment is in the form of a liquid, paste, or gel, wherein the detergent composition disposed in the second compartment is in the form of a powder, wherein the detergent composition comprises a nonionic surfactant at a level of from about 0.2% to about 10% by weight of the detergent composition.

### Claim 2 (depends on 1)

The unit dose machine dishwashing article of claim 1, wherein the first and second compartments are arranged in a generally superposed relationship.

### Claim 3 (depends on 1)

The unit dose machine dishwashing article of claim 1, wherein the nonionic surfactant comprises a low cloud point nonionic surfactant.

### Claim 4 (depends on 1)

The unit dose machine dishwashing article of claim 1, wherein the nonionic surfactant comprises a high cloud point nonionic surfactant.

### Claim 5 (depends on 1)

The unit dose machine dishwashing article of claim 1, wherein the nonionic surfactant is selected from the group consisting of: an alkoxylated surfactant, ethoxylated-propoxylated alcohols, epoxy-capped poly(oxyalkylated) alcohol, ether-capped poly(oxyalkylated) alcohol surfactant, block polyoxyethylene-polyoxypropylene polymeric compound, and mixtures thereof.

### Claim 6

A unit dose machine dishwashing article comprising a water-soluble pouch containing a detergent composition, wherein the water-soluble pouch comprises a plurality of compartments in a generally superposed relationship, each compartment containing one or more detergent active or auxiliary components that form the detergent composition, wherein the detergent composition comprises a nonionic surfactant at a level of from about 0.2% to about 10% by weight of the detergent composition.

### Claim 7 (depends on 6)

The unit dose machine dishwashing article of claim 6, wherein the one or more detergent active or auxiliary components in a first compartment is in the form of a liquid, paste, or gel.

### Claim 8 (depends on 7)

The unit dose machine dishwashing article of claim 7, wherein the nonionic surfactant of the detergent composition is disposed in the first compartment.

### Claim 9 (depends on 6)

The unit dose machine dishwashing article of claim 6, wherein the one or more detergent active or auxiliary components in a second compartment is in the form of a powder or densified powder.

### Claim 10 (depends on 6)

The unit dose machine dishwashing article of claim 6, wherein the nonionic surfactant comprises a low cloud point nonionic surfactant.

### Claim 11 (depends on 6)

The unit dose machine dishwashing article of claim 6, wherein the nonionic surfactant comprises a high cloud point nonionic surfactant.

### Claim 12

A unit dose machine dishwashing article comprising a water-soluble pouch containing a detergent composition, wherein the water-soluble pouch comprises at least one compartment, wherein the at least one compartment comprises at least a portion of the detergent composition, wherein the detergent composition in the at least one compartment is in the form of a liquid, paste, or gel, wherein the detergent composition comprises a nonionic surfactant at a level of from about 0.2% to about 10% by weight of the detergent composition.

### Claim 13 (depends on 12)

The unit dose machine dishwashing article of claim 12, wherein the at least one compartment is a first compartment, the water-soluble pouch comprising a second compartment, wherein the second compartment comprises at least a portion of the detergent composition.

### Claim 14 (depends on 13)

The unit dose machine dishwashing article of claim 13, wherein the detergent composition in the second compartment is in the form of a powder.

### Claim 15 (depends on 12)

The unit dose machine dishwashing article of claim 12, wherein the first and second compartments are arranged in a generally superposed relationship.

### Claim 16 (depends on 12)

The unit dose machine dishwashing article of claim 12, wherein the nonionic surfactant comprises a low cloud point nonionic surfactant.

### Claim 17 (depends on 12)

The unit dose machine dishwashing article of claim 12, wherein the nonionic surfactant comprises a high cloud point nonionic surfactant.

### Claim 18 (depends on 12)

The unit dose machine dishwashing article of claim 12, wherein the nonionic surfactant is selected from the group consisting of: an alkoxylated surfactant, ethoxylated-propoxylated alcohols, epoxy-capped poly(oxyalkylated) alcohol, ether-capped poly(oxyalkylated) alcohol surfactant, block polyoxyethylene-polyoxypropylene polymeric compound, and mixtures thereof.
