ABSTRACT:
The pack is adapted to store separately and allow mixing of a plurality of components and subsequent dispensing of the mixture. It comprises an outer container (1) and a preferentially rupturable inner container (2) having its outer surface sealed to the inner surfaces of said outer container walls at a median point of the outer container and adjacent an end of said inner container. The wall of said inner container (2) between seals (3) defines a first compartment (9) within said inner container (2) to one side of said seal (3) and a second compartment (7) within said outer container (1) to the other side of said seal (3). A recloseable inlet and outlet means (4,5) communicates with said second compartment (7). One way of making the pack is to place the inner container (2) within one open end of the open ended outer container (1), inserting a spatula into the inner container (2) to separate its two sides, and sealing line an outer surface of said inner container means to an inner surface of said outer container. Other methods are also disclosed. The pack is useful for storing, mixing and dispensing agriculturally useful two or component compositions, such as seed coating compositions containing micro-organisms.
