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.

1. A method for packaging single use amounts of any of a liquid detergent or liquid fabric softener in a non-closable, non-reusable, non-storable container, comprising the steps of: a) forming a self-standing container with an open well, of a size sufficient to contain enough liquid detergent or fabric softener sufficient for a single average wash load, with said well having an opening, completely peripherally bounded with a peripheral outwardly extending short ledge; b) filling the container with an amount of the liquid detergent or fabric softener, sufficient only for about a single average wash load; c) placing a cover sheet of a sealable material on the ledge around the opening of the well and enclosingly across the opening of the well and fully sealing the cover sheet to sealingly enclose the liquid within said container, wherein said cover sheet is congruently sized to the surface having the area dimension comprising the opening of the well and the ledge therearound, and wherein a portion of the cover sheet is manually accessible for gripping in peeling off the cover sheet from the container when the detergent or fabric softener is to be used; wherein the seal is of sufficient tensile strength to resist accidental opening of the container but wherein the seal has a low peel strength for facilitated peeling removal of the cover sheet without jerking or the leaving of a remaining residue. 2. The method of claim 1, wherein said cover sheet comprises a printed metal foil sheet with product indicia thereon.3. The method of claim 1, wherein said amount of liquid detergent or fabric softener is a single wash load quantity of up to about 4 ounces, and said container is adapted for the containment thereof.4. The method of claim 1, wherein said container comprises a frusto-conical configuration.5. The method of claim 1, said sealing comprises polymeric adhesive sealing.6. The method of claim 1, wherein said ledge is formed with a flat upper surface adapted for sealing to said cover sheet, and a channeled lower surface to impart rigidity to said ledge.7. A container, with one of liquid detergent and liquid fabric softener sealingly contained therein, for single use with an average wash load, said container being self-standing and, formed from a leak resistant self supporting material and having an open well of a size sufficient to contain enough liquid detergent or fabric softener sufficient for a single average wash load, with said well having an opening, completely peripherally bounded with a peripheral outwardly extending short ledge; said container further comprising a cover sheet on the ledge around the opening of the well and enclosingly across the opening of the well and fully sealed to said ledge to sealingly enclose the liquid within said container, wherein said cover sheet is congruently sized to the surface having the area dimensions comprising the opening of the well and the ledge therearound, and wherein a portion of the cover sheet is manually accessible for gripping in peeling off the cover sheet from the container when the detergent or fabric softener is to be used; wherein the seal is of sufficient tensile strength to resist accidental opening of the container but wherein the seal has a low peel strength for facilitated peeling removal of the cover sheet without jerking or the leaving of a remaining residue. 8. The container of claim 7, further comprising an adhesive seal disposed between the cover sheet and the ledge.9. The container of claim 8, said adhesive seal comprising a peelable heat seal.10. The container of claim 7, said detergent comprising a bleaching agent.11. A container, with a liquid comprising a bleach or bleaching agent sealingly contained therein, for single use with an average wash load, said container being self-standing and, formed from a leak resistant self supporting material and having an open well of a size sufficient to contain enough liquid detergent or fabric softener suf ficient for a single average wash load, with said well having an opening, completely peripherally bounded with a peripheral outwardly extending short ledge; said container further comprising a cover sheet on the ledge around the opening of the well and enclosingly across the opening of the well and fully sealed to said ledge to sealingly enclose the liquid within said container, wherein said cover sheet is congruently sized to the surface having the area dimensions comprising the opening of the well and the ledge therearound, and wherein a portion of the cover sheet is manually accessible for gripping in peeling off the cover sheet from the container when the detergent or fabric softener is to be used; wherein the seal is of sufficient tensile strength to resist accidental opening of the container but wherein the seal has a low peel strength for facilitated peeling removal of the cover sheet without jerking or the leaving of a remaining residue. 12. The container of claim 11, further comprising an adhesive seal disposed between the cover sheet and the ledge.13. The container of claim 12, said adhesive seal comprising a peelable heat seal.14. The container of claim 13, said adhesive seal comprising a olymeric adhesive seal.
