ABSTRACT:
A dispensing device for a soluble or dispersible material is disclosed, which device comprises a tube formed of a liquid-impermeable material and of unitary construction, the tube being closed at both ends and having perforations along a portion of its length at or close to one end, and containing a soluble granular material. Preferably the lower end of the tube has a flattened, paddle-like portion, and the perforations are arranged linearly along opposite sides of the tube aligned with the edges of the flattened portion. The tube is advantageously divided into two compartments by a temporary seal; in this way, the material can be kept in one compartment which is free from perforations until the device is to be used.
