Embodiment Construction

[0070] The various cases of packaging are represented in FIG. 1 in the form of structures and configurations obtained by dipping from a melt or solution of the packaging material. In Figures 1a to 1g, a capsule comprising a water-dispersible or soluble multilayer and / or multipart material in the form of an outer shell (11) and a connecting part (12, 13) is represented.

[0071] Figure 1a shows a capsule having a central single layer of fast dissolving wrapper and peripheral double layers of fast-slow and slow-fast dissolving wrapper, respectively, adapted to provide an aforesaid weakened connection or weak point. As an alternative to Fig. 1, in Fig. 1b, a capsule is shown with a central and peripheral single layer of fast-dissolving and slow-dissolving packaging material and an outer layer of fast-slow dissolving packaging material, respectively. Variations of these structures can be envisaged and determined according to the desired ease of manufacture and desired release char...

Abstract

The invention is concerned with controlled release packaging comprising packaging material which is at least partially or substantially completely dispersible or dissolvable in an effective amount of a water-containing substance and which is adapted to comprise, contain or enclose one or more substances wherein the packaging is adapted for release of comprised, contained or enclosed substances in response to a predetermined stimulus in predetermined manner to a desired locus with substantially simultaneous or subsequent partial or complete dispersal or dissolving thereof.

Description

technical field [0001] The present invention relates to an improved package which is at least partially or substantially completely soluble in water for the controlled release of a substance, a method for controlled release using the package, a method for manufacturing the same, which releases a wide range of The use of the substance and the novel product containing the packaging. Background technique [0002] Water soluble packages are known in the literature for dispensing substances which dissolve partially or completely leaving little or no residue. Such packaging materials are used by themselves in self-contained packs, or for use in conjunction with non-dissolvable dispensers. These packaging materials release the contained substances, such as hazardous substances, fungicides, etc., by dissolving concentrates, such as detergents, etc. in water. [0003] The advantages of this type of packaging are due to the reduced risk of splashing and spilling of hazardous substan...
