Claims
- 1. A process for the production of water-soluble pouches comprising the steps:
(a) drawing a first film into a mould to form a first compartment; (b) adding a composition to said first compartment; (c) forming a second compartment by drawing a second film into said mould; wherein the second compartment comprises a composition and the second film is drawn in to the mould by means of suction applied through at least one perforation in the first film.
- 2. A process according to claim 1 wherein at least one of the compositions is a cleaning composition.
- 3. A process according to claim 1 wherein the composition in the first compartment is a particulate.
- 4. A process according to claim 1 wherein the perforation has a diameter of less than about 2 mm.
- 5. A process according to claim 1 wherein the suction is from about 950 to about 30 mbar.
- 6. A process according to claim 1 wherein the film material is selected from the group consisting of: polyacrylates and water-soluble acrylate copolymers; methylcellulose; carboxymethylcellulose sodium; dextrin; ethylcellulose; hydroxyethyl cellulose; hydroxypropyl methylcellulose; maltodextrin; polymethacrylates; and mixtures thererof.
- 7. A process according to claim 1 wherein the film material is selected from the group consisting of: polyvinyl alcohols; polyvinyl alcohol copolymers; hydroxypropyl methyl cellulose; and mixtures thereof.
- 8. A process according to claim 1 wherein the perforations are pre-formed.
- 9. A water-soluble pouch obtained by a process according to claim 1.
- 10. A process for the production of water-soluble pouches comprising the steps:
(a) drawing a first film into a mould to form a first compartment; (b) adding a composition to the first compartment; (c) forming a second compartment by drawing a second film into the mould by means of suction applied through at least one perforation in the first film; (d) compacting the composition in the first compartment; (e) adding a composition to the second compartment; (f) covering the second compartment with a third film; and (g) sealing the pouch.
- 11. A process according to claim 10 wherein at least one of the compositions is a cleaning composition.
- 12. A process according to claim 10 wherein the composition in the first compartment is a particulate.
- 13. A process according to claim 10 wherein the perforation has a diameter of less than about 2 mm.
- 14. A process according to claim 10 wherein the suction is from about 950 to about 30 mbar.
- 15. A process according to claim 10 wherein the film material is selected from the group consisting of: polyacrylates and water-soluble acrylate copolymers; methylcellulose; carboxymethylcellulose sodium; dextrin; ethylcellulose; hydroxyethyl cellulose; hydroxypropyl methylcellulose; maltodextrin; polymethacrylates; and mixtures thererof.
- 16. A process according to claim 10 wherein the film material is selected from the group consisting of: polyvinyl alcohols; polyvinyl alcohol copolymers; hydroxypropyl methyl cellulose; and mixtures thereof.
- 17. A process according to claim 10 wherein the perforations are pre-formed.
- 18. A water-soluble pouch obtainable by a process according to claim 10.
- 19. A water-soluble pouch obtained by a process according to claim 15.
- 20. A water-soluble pouch obtained by a process according to claim 6.
