Water soluble containers comprising at least two compartments

Abstract

A process for producing a water-soluble article comprising a first compartment containing a first composition and a second compartment comprising a second composition, which process comprises: a. producing a first compartment; b. filling the first compartment with the first composition; and either c. providing a sealing film comprising the second composition and sealing the first compartment with the sealing film; or d. sealing the first compartment with a sealing film; producing a second compartment from the of sealing film of the first compartment; filing the second compartment with the second composition; and sealing the second compartment with a second sealing film. (same again)

1 . A process for producing a water-soluble article comprising a first compartment containing a first composition and a second compartment comprising a second composition, which process comprises: 
 a. producing a first compartment;    b. filling the first compartment with the first composition; and    either    c. providing a sealing film comprising the second composition and sealing the first compartment with the sealing film;    or    d. sealing the first compartment with a sealing film; producing a second compartment from the first compartment and/or the sealing film of the first compartment; filling the second compartment with the second composition; and sealing the second compartment with a second sealing film.    
     
     
         2 . A process as claimed in  claim 1  wherein the first compartment is made from a film and the second compartment is formed from the sealing film and the film of the first compartment.  
     
     
         3 . A process as claimed in  claim 2  wherein the second compartment is formed from the sealing film or from the film of the first container.  
     
     
         4 . A process as claimed in any claim from  2  to  3  wherein the sealing film of the first compartment is part of a continuous web.  
     
     
         5 . A process for producing a water-soluble article comprising a first compartment containing a first composition, said compartment being sealed with a sealing film, wherein said sealing film comprises a second composition, which process comprises: 
 a. producing a first compartment;    b. filling the first compartment with the first composition; and    c. providing a sealing film comprising the second composition and sealing the first compartment with the sealing film.    
     
     
         6 . A process according to any claim from  1  to  5  wherein the first compartment and the sealing film comprise a poly(vinyl alcohol).  
     
     
         7 . A process according to any one of the preceding claims wherein the first compartment has been formed by thermoforming.  
     
     
         8 . A process according to  claim 5  wherein the first compartment has been made by injection moulding.  
     
     
         9 . A process according to any one of the preceding claims wherein the first composition is a particulate solid, a gel or a liquid.  
     
     
         10 . A process according to  claim 5  wherein one of the compartments has been formed by a vertical form fill sealing method.  
     
     
         11 . A process according to any one of  claims 1  to  9  wherein at least one compartment has been formed by thermoforming.  
     
     
         12 . A process according to any one of the preceding claims wherein the second composition is a particulate solid, a gel, a liquid or a compressed solid.  
     
     
         13 . A process according to any one of the preceding claims wherein the first composition and the second composition are each a fabric care, surface care or dishwashing composition.  
     
     
         14 . A process according to  claim 13  wherein each composition is a dishwashing, water-softening, laundry or detergent composition or a rinse aid.  
     
     
         15 . A process according to  claim 13  wherein each composition is a disinfectant, antibacterial or antiseptic composition or a refill composition for a trigger-type spray.  
     
     
         16 . A process according to any one of  claims 1  to  12  wherein the first composition and the second composition are each compositions which are intended to be released into an aqueous environment for example, a pharmaceutical or neutraceutical composition, an agricultural or pesticidal composition or a hazardous compound potentially toxic or damaging to health or to the environment.  
     
     
         17 . A water-soluble article obtainable by a process as defined in any one of the preceding claims.
