<p>A method of packaging liquid detergent or fabric softener for single load use comprising thermoforming a container (1) from a thermoplastic material such as polypropylene, polyethylene, polystyrene and the like, to a size sufficient to contain a 3-4 ounce amount of liquid detergent (20) in a well thereof. The container comprises an open well with a peripheral lip (2) an open end thereof. A printed foil strip (10), sized to cover the opening and at least a full circumferential portion of the container lip is heat sealed to the thermoplastic after the detergent is disposed therein. The foil and heat seal are of sufficient strength to retain the 3-4 ounces of liquid detergent even in an obverted position with jostling such as drug transport. Because of the heat seal, the container is not reclosable and storable and the full contents must be used once the container is opened, i.e., for a single use.</p> |
