Abstract

A process for preparing a water-soluble article comprising a water-soluble primary thermoformed component and a water-soluble secondary component attached thereto, which comprises placing the secondary component in the cavity of a thermoforming mould, thereafter placing a primary component in or over the thermoforming mould, forming the primary thermoformed component by thermoforming the primary component in the mould, and removing the article from the mould.

Claims

exact text as granted — not AI-modified

1 . A process for preparing a water-soluble article comprising a water-soluble primary thermoformed component and a water-soluble secondary component attached to the outside thereof, which comprises placing the secondary component in the cavity of a thermoforming mould, thereafter placing a primary component in or over the thermoforming mould, forming the primary thermoformed component by thermoforming the primary component in the mould, and removing the article from the mould.

2 . A process according to claim 1 wherein the primary component is a film.

3 . A process according to claim 1 wherein the primary thermoformed component comprises a film.

4 . A process according to any claim from 1 to 3 wherein the primary component is thermoformed into a pocket surrounded by a sealing portion and wherein the process additionally comprises the steps of filling the pocket with a primary composition and closing the pocket, for example by placing a film on top of the filled pocket and across the sealing portion and sealing the polymeric films together at the sealing portion.

5 . A process according to claim 1 or 3 wherein the primary component is a sealed container containing a primary composition.

6 . A process according to claim 5 wherein the sealed container is prepared by thermoforming a film into a pocket surrounded by a sealing portion, filling the pocket with a primary composition and closing the pocket, for example by placing a film on top of the filled pocket and across the sealing portion and sealing the films together at the sealing portion.

7 . A process according to any claim from 4 to 6 wherein the composition is a solid, a gel or a liquid.

8 . A process according to any one of the preceding claims wherein the secondary component is a compressed solid or a container containing a secondary composition.

9 . A process according to claim 8 wherein the secondary component is a container comprising a polymeric film containing a solid, a gel or a liquid.

10 . A process according to any one of the preceding claims wherein the primary component and/or the secondary component comprises a poly(vinyl alcohol).

11 . A process according to any one of the preceding claims wherein the article is for use in dishwashing, fabric care or surface care.

12 . A process according to claim 11 wherein the primary component comprises a dishwashing, water-softening, laundry or detergent composition.

13 . A process according to claim 11 or 12 wherein the secondary component comprises a dishwashing, water-softening, laundry or detergent composition or a rinse-aid.

14 . A process according to any one of claims 1 to 10 wherein the primary component and/or secondary component comprises a disinfectant, antibacterial or antiseptic composition.

15 . A process according to any one of claims 1 to 10 or 14 wherein the article comprises a refill composition for a trigger-type spray.

16 . A process according to any one of claims 1 to 10 wherein the article comprises an agricultural composition.

17 . A water-soluble article comprising a water-soluble primary component which is a thermoformed container containing a primary composition, and a water-soluble secondary component attached to the outside thereof.

18 . An article according to claim 17 wherein the primary composition is a solid, a gel or a liquid.

19 . An article according to claim 17 or 18 wherein the secondary component is a compressed solid or a container containing a secondary composition.

20 . An article according to claim 19 wherein the secondary component is a container comprising a polymeric film containing a solid, a gel or a liquid.

21 . An article according to any one of claims 17 to 20 wherein the primary component and/or the secondary component comprises a poly(vinyl alcohol).

22 . An article according to any one of claims 17 to 21 wherein the article is for use in dishwashing, fabric care or surface care.

23 . An article according to claim 22 wherein the primary composition is a dishwashing, water-softening, laundry or detergent composition.

24 . An article according to claim 22 or 23 wherein the secondary component comprises a dishwashing, water-softening, laundry or detergent composition or a rinse-aid.

25 . An article according to any one of claims 18 to 21 wherein the primary composition and/or secondary component comprises a disinfectant, antibacterial or antiseptic composition.

26 . An article according to any one of claims 18 to 21 or 25 wherein the article comprises a refill composition for a trigger-type spray.

27 . An article according to any one of claims 17 to 21 wherein the article comprises an agricultural composition.
