Abstract
A water-soluble container (1) has at least one discrete chamber (30, 31; 130, 131) for containing product. At least part (20, 27) of the entirety (125a, 125b) of a container wall (11, 25; 125a, 125b) of the at least one chamber dissolves before the remainder of the chamber dissolves to allow product to escape.
Claims17
1:
- A water-soluble container (1) comprising at least one discrete chamber (30, 31;
- 130, 131) for containing product, at least a part (20, 27) of a first wall (11, 25;
- 125a, 125b) of said at least one chamber 30, 31;
- 130, 131) will dissolve before a remainder wall of the chamber dissolves to allow product to escape, the at least part (20, 27) of the first wall (11, 25) which dissolves before the remainder wall dissolves defines a releasable part (19, 26), and when the at least part (20, 27) of the first wall (11, 25) dissolves the releasable part (19, 26) is released undissolved.
1 more element
2:
- The container (1) as defined in claim 1, wherein the releasable part (19, 26) is a panel (19, 26) and the at least part (20, 27) of the first wall (11, 25) at least partly surrounds the panel (19, 26) whereby the panel (19, 26) is released when the at least part (20, 27) of the first wall (11, 25) has dissolved.
3:
- The container (201) as defined in claim 1, wherein the at least part of the first wall (225) includes at least one clip element (220) which retains the releasable part (225) until dissolved.
4:
- The container (1) as defined in claim 1, wherein the at least part (20, 27) of the first wall (11, 25) is thinner than the remainder wall of the container.
5:
- The container (1) as defined in claim 4, wherein the material thinning (20, 27) is arranged on the interior surface of the chamber wall.
6:
- The container (1) as defined in claim 1, wherein the container is formed by injection moulding.
7:
- The container (1) as defined in claim 1, wherein at least part of the material from which the container is formed is polyvinyl alcohol.
8:
- The container (1) as defined in claim 1, wherein at least part of the material from which the container is formed is a polylactic acid.
The container (1) as defined in claim 1, wherein at least part of the material from which the container is formed is starch-based.
10:
- The container (1) as defined in claim 1, wherein the whole of the container is formed from the same material.
11:
- The container (1) as defined in claim 1, wherein the container is flexible.
12:
- (canceled)
13:
- The container (1) as defined in claim 1 including a second discrete chamber (130, 131) for containing product, at least a part of a first wall (125a, 125b) of said second chamber (130, 131) will dissolve before a remainder wall of the second chamber dissolves to allow product to escape, and the at least part of the first wall (125a, 125b) of the second chamber which dissolves before the remainder wall thereof dissolves at a different dissolution rate than the dissolution rate of the at least part (20, 27) of the first wall (11, 25) whereby products in the chambers escape sequentially therefrom.
14:
- The container (1) as defined in claim 13, wherein the container is formed by injection moulding.
15:
- The container (1) as defined in claim 13, wherein at least part of the material from which the container is formed is polyvinyl alcohol.
16:
- The container (1) defined in claim 13, wherein at least part of the material from which the container is formed is a polylactic acid.
The container (1) as defined in claim 13, wherein at least part of the material from which the container is formed is starch-based.
