Abstract

A process for preparing a water-soluble container comprising at least two compartments which comprises: a. forming a first pocket in a first water-soluble film by thermoforming or vacuum forming the first water-soluble film in a mould; b. filling the first pocket with a first composition; c. closing the first pocket with a second water-soluble film to produce an intermediate container; d. moving the intermediate container by deforming the mould to provide a second pocket; e. filling the second pocket with a second composition; and f. closing the second pocket with a third water-soluble film.

Claims

exact text as granted — not AI-modified
1 . A process for preparing a water-soluble container comprising at least two compartments which comprises the steps of: 
 a. forming a first pocket in a first water-soluble film by thermoforming or vacuum forming the first water-soluble film in a mould;    b. filling the first pocket with a first composition;    c. closing the first pocket with a second water-soluble film to produce an intermediate container;    d. moving the intermediate container by deforming the mould to provide a second pocket;    e. filling the second pocket with a second composition; and    f. closing the second pocket with a third water-soluble film.    
   
   
       2 . A process according to  claim 1  wherein the second pocket is bounded by the second water-soluble film.  
   
   
       3 . A process according to  claim 1  wherein the mould is deformed by moving at least part of the bottom of the mould to move the intermediate container and to form the second pocket having a bottom formed from the second water-soluble film and sides formed from the first water-soluble film and optionally the second water-soluble film.  
   
   
       4 . A process according to  claim 1  wherein at least one of the first water-soluble film, second water-soluble film and third water-soluble film is a poly(vinyl alcohol) film.  
   
   
       5 . A process according to  claim 1  wherein the first composition and second composition are each selected from: fabric care, surface care or dishwashing compositions.  
   
   
       6 . A process according to  claim 5  wherein the first composition and second composition are each selected from dishwashing, water-softening, laundry, detergent and rinse-aid compositions.  
   
   
       7 . A water-soluble container comprising: 
 a first closed pocket of a thermoformed or vacuum-formed first water-soluble film containing a first composition, said first pocket closed with a second water-soluble film;    an adjacent second closed pocket containing a second composition, said second pocket closed with a third water-soluble film.    
   
   
       8 . A water-soluble container according to  claim 7  wherein at least one of the first water-soluble film, second water-soluble film and third water-soluble film is a poly(vinyl alcohol) film.  
   
   
       9 . A water-soluble container according to  claim 7  wherein the first composition and second composition are each selected from fabric care, surface care or dishwashing compositions.  
   
   
       10 . A water-soluble container according to  claim 7  wherein the first composition and second composition are each selected from dishwashing, water-softening, laundry, detergent and rinse-aid compositions.
