Abstract

A detergent multi-compartment pouch having a plurality of water-soluble films forming a plurality of compartments the pouch comprising two side-by-side compartments superposed onto another compartment wherein at least two different compartments contain two different compositions.

Claims

1. A detergent multi-compartment pouch having a plurality of water-soluble films forming a plurality of compartments the pouch comprising two side-by-side compartments superposed onto another compartment wherein at least two different compartments contain two different compositions.

2. A detergent pouch according to claim 1 wherein one of the compartments contains a composition in liquid form and another compartment contains a composition in solid form wherein the solid and liquid compositions are in a weight ratio of from about 20:

1 to about 1;

20.

3. A detergent pouch according to claim 1 wherein the two side-by-side compartments contain liquid compositions and another compartment contains a solid composition.

4. A detergent pouch according to claim 1 wherein one of the compartments contains a composition in liquid form and another compartment contains a composition in solid form and wherein the pouch has a volume of from about 10 ml to about 30 ml and preferably the weight of the solid composition is from about 10 to about 26 grams and the weight of the liquid composition is from about 0.5 to about 4 grams.

5. A detergent pouch according to claim 1 wherein at least two of the films have different solubility.

6. A detergent pouch according to claim 1 wherein one of the compartments contains a composition in liquid form and another compartment contains a composition in solid form said solid and liquid compositions are in a weight ratio of from about 20:

1 to about 1;

20 and wherein at least one composition comprises an enzyme and another composition comprises a bleach and preferably one of the films that form the compartment containing the enzyme-containing composition has a solubility such as it releases its contents prior to the films that form the compartment containing the bleach-containing composition in the main-wash cycle of an automatic dishwashing machine.

7. A detergent pouch according to claim 1 wherein one of the compartments contains a composition in liquid form and another compartment contains a composition in solid form said solid and liquid compositions are in a weight ratio of from about 20:

1 to about 1;

20 and wherein at least one liquid composition comprises a non-ionic surfactant, preferably having a cloud point above 60°

.

8. A detergent pouch according to claim 1 wherein one of the compartments contains a composition in liquid form and another compartment contains a composition in solid form said solid and liquid compositions are in a weight ratio of from about 20:

1 to about 1;

20 and wherein at least one of the liquid compositions is a rinse aid composition and the films that form the compartment containing the rinse aid is insoluble during the main wash and has a solubility such as it releases its contents in the rinse cycle of an automatic dishwashing machine.

9. A method of dishwashing in an automatic dishwashing machine using a detergent pouch according to claim 6 comprising the steps of:

a) placing the pouch into the dispenser and releasing it during the main-wash cycle; and

b) releasing at least one enzyme-containing composition into the wash liquor prior to the delivery of the bleach-containing composition.

10. A method of dishwashing in an automatic dishwashing machine using a detergent pouch according to claim 8 comprising the steps of:

c) placing the pouch into the dispenser and releasing it during the main-wash cycle; and

d) releasing a composition into the wash liquor during the main-wash cycle and at least one liquid compositions into the rinse liquor during the rinse cycle.
