Abstract
The present invention is directed to a novel single, unit-dose drycleaning article in which at least a portion thereof dissolves in a drycleaning solvent during the drycleaning cycle for releasing a premeasured amount of a drycleaning additive contained within the article. The single, unit-dose drycleaning article is generally in the form of a sealed tub formed of a polystyrene. The unit-dose tub preferably dissolves within about one minute after being in contact with the drycleaning solvent to ensure release and adequate mixing of the drycleaning additive with the drycleaning solvent to effect maximum drycleaning results. In an alternative form, the single, unit-dose drycleaning article may be partially formed with a material that dissolves in a drycleaning solvent. In that form, it is preferred to locate the single, unit-dose drycleaning article in a sealable enclosure, such as a sealable bag, net or basket, which is formed of a material that is drycleaning solvent-insoluble, drycleaning solvent-permeable, such as a polyethylene, polypropylene, nylon, polyester, cotton, metal, etc., so that the remaining or non-dissolved portion of the single, unit-dose drycleaning article can be retrieved at the end of the drycleaning cycle.
