Temperature release containers.

摘要

Temperature Release Containers for dispensing a liquid or powder fabric conditioner wherein the container (20, 40) is caused to break or detach in response to temperature change, either by constriction or expansion of a thermo-responsive element (24, 44) or by use of a two-part container (50, 60) wherein the degree of contraction of a first part (51, 61) in cold rinse water of a washing machine is substantially greater than the second part (54, 62), whereby the latter detaches from the first part. Thus, when a container of this type is placed in a clothes washer, the washing cycle is set to a warm or hot temperature and the final rinsing cycle is set to cold. The cold water causes the container to break or to separate, so that the conditioner is released into the rinse water.
