Abstract
A method of packaging liquid detergent or fabric softener for single load use comprising forming a container from a thermoplastic material such as polypropylene, polyethylene, polystyrene and the like, to a size sufficient to contain a 3-4 ounce amount of a liquid bleach or liquid bleaching agent containing detergent in a well thereof. The container comprises an open well with a peripheral lip an open end thereof. A printed foil strip, sized to cover the opening and at least a full circumferential portion of the container lip is heat or adhesive sealed to the plastic after the detergent is disposed therein. The foil and seal are of sufficient strength to retain the 3-4 ounces of liquid bleach or bleaching agent containing detergent even in an obverted position with jostling such as during transport. Because of the nature of the seal, the container is not readily fully reclosable, and the full contents must, as a practical matter, be used once the container is opened, i.e., single use.
