Embodiment I

[0088] Use a cylindrical mold with a diameter of 10 mm and a depth of 8 mm. There is a rubber layer 0.5 mm thick on the peripheral edge of the mould. There are holes in the mold material which allow a vacuum to be applied to the mold. A piece of Chris-Craft M-8630 or CXP4087 film was placed on top of the mold and secured. Applying vacuum draws the film inside the mold and pulls the film flush with the inner surface of the mold. Composition B or D (see below) is poured into the mold, preferably in such an amount as to nearly or completely fill the mold. Then, another sheet of the same film substance was placed over the mold and sealed to the first by applying a flat ring piece heated at medium pressure over a rubber ring at the edge of the mold to seal the two sheets together. Heat seal together to form a second pouch.

[0089] Use another cylindrical mold with a diameter of 45 mm and a depth of 25 mm. There is a 1.0 mm thick layer of rubber around the peripheral edge of t...

Abstract

The present invention relates to an article comprising a first capsule made of a water-reactive substance, comprising: a) a first solid or liquid composition; and b) a second capsule made of a water-reactive substance, in which The interior includes a second solid or liquid composition. The present invention also provides methods of making such articles. Preferably the article comprises a fabric cleaning composition, a dishwashing or hard surface cleaning composition or a fabric care composition for laundry use.

Description

field of invention [0001] The present invention relates to an article comprising a first bladder made of a water-soluble film. The invention also relates to articles capable of sequential release of at least two different compositions. Background of the invention [0002] In the market we can find cleaning products and fabric care products in various forms such as granular compositions, liquid compositions and tablets. It is also known that cleaning products can be placed in water soluble or water permeable unit dose pouches which release said product when added to water. Such bags, such as laundry bags, may have two compartments, each containing a different, usually mutually incompatible, component. These compartments are usually connected to one another. [0003] We have found an improved method which enables bags containing two or more compartments to have, for example, different compositions in each compartment. This novel bag or article of the present invention comp...
