ABSTRACT:
Disclosed is an indicator (15, 35) for determining the level of contents in an opaque, plastic container (10, 30, 40). The container (10, 30, 40) is filled with a solid chemical (11), such as a detergent. A spray of warm or hot water (19) impinges upon the eroding surface (16) of the solid chemical (11) to produce a chemical solution. The container (10, 30, 40) is provided with a thermo-chromatic strip (15, 35) or thermo-chromatic surface (41) for detecting the level of solid chemical (11) within the plastic capsule (10). A method of manufacturing the dispensing container (10, 30, 40) is also disclosed.
