Claims
- 1. A liquid or solid composition in a pouch, the pouch comprising one or more compartments and the composition one or more components, the compartment being formed from a stretchable water-disintegrating, water-soluble or water-dispersible material of non-uniform thickness.
- 2. A composition as in claim 1 which is solid, preferably particulate.
- 3. A composition in a pouch according to claim 1 or 2 obtainable by a process comprising the steps of:
a) stretching a stretchable material, preferably a film, forming an open compartment, preferably by introducing the material in a mould and stretching the material into the mould to form the open compartment in the shape of the mould; b) introducing the component in the open compartment, such that at least 95% of the volume of the open compartment is filled with the component; c) subsequently closing the open compartment.
- 4. A composition according to claim 3 whereby the component is particulate and the process comprises the step of increasing the bulk density of the component with 5% to 45%, preferably 5% to 35% or even 20%, or even 10% to 25%.
- 5. A composition according to claim 3 or 4 whereby step a) or b) and c) are performed under reduced pressure which is lower than atmospheric pressure, preferably by applying a vacuum.
- 6. A composition according to claim 3 or 4 whereby in step b) the component is particulate and introduced in the open compartment such that at least 100%, preferably at least 110%, of the volume of the open compartment is occupied by the component.
- 7. A composition in a pouch according to any preceding claim whereby the compartment is formed from an elastic material, preferably a film.
- 8. A composition according to any of claims 3 to 6 whereby the compartment is formed from a stretchable, shrinkable material and in step c) the surface area of the compartment is reduced during or subsequent to closing the open compartment by shrinking the open compartment and/or compartment, preferably by heat-shrinking.
- 9. A composition according to any preceding claim whereby the compartment is formed from a material of non-uniform thickness having a variation in thickness of at least 40%, preferably up to 500%.
- 10. A composition in a pouch according to any preceding claim whereby the stretchable material has a maximum stretching degree of at least 200% and preferably an elastic recovery of from 50% to 100%.
- 11. A composition in a pouch according to any preceding claim whereby the compartment and the pouch are water-soluble.
- 12. A composition in a pouch according to any preceding claim whereby the compartment is formed from a film comprising polyvinyl alcohol polymer.
- 13. A composition in a pouch according to any preceding claim which is a cleaning composition in a pouch, preferably a laundry or dish washing detergent in a pouch.
- 14. A process as in claim 3 for making the pouched product as in any of claims 1 to 13.
