  • Patent number: 4776972
    Abstract: The invention relates to products useful for home laundering, and more particularly to adjustable strength bleaching compositions, highly advantageous packaging of such compositions, and a method of bleaching involving the combination of the two. More specifically, the invention concerns a highly practical and saleable laundry aid which can be used both on sensitive fabrics/dyes as an all-fabric safe oxygen bleach, and on less vulnerable fabrics/dyes as a much more effective hypohalite bleach of potency similar to that of liquid chlorine bleach. The invention is concerned with the use of an alkali metal halide activator with an oxygen bleach which is packaged in a two compartment package to keep the components separate before use.

  • Patent number: 4720351
    Abstract: The invention relates generally to products useful for home laundering, and more particularly to a product which incorporates a prespotter with a detergent and having one or more of the following separate functions: detergency, fabric softening, stain removal, bleaching, and bluing; with the advantage being that both the detergent and the prespotter are uniquely packaged together as one product, negating the need to purchase and store separate products for each end use function, and also, unavoidably providing presentation of the prespotter to the detergent user at the time of laundering. The invention also concerns methods of use of such products during laundering.

  • Patent number: 4615814
    Abstract: A bead, useful in a fabric aqueous laundering process to impart to the fabric, when dried, at least one of the properties (i) softness, and (ii) antistatic effect, comprises a porous substrate, and substance absorbed onto said substrate to produce at least one of said (i) and (ii) properties in the fabric. A barrier layer may be formed about said substrate and characterized as dispersing in laundry wash water; a solubilizing or dispersion aid such as a nonionic surfactant may be mixed with said substance and also absorbed onto the substrate; and a hardener may be mixed with said substance and also absorbed onto the substrate.

  • Patent number: 4583681
    Abstract: A carton has upright side walls, end walls, multiple inner flaps at the top of the carton, and an outermost flap at the carton top to cover the folded inner flaps. An elongated opening is provided through the outer flap, and a substantially flat strip handle extends at least partly in that opening and has opposite end portions retained to the outer flap and extending beneath same.A substantially flat closure means closes the opening beneath said handle and isolates said handle from said inner flaps, the closure means including a first closure sheet underlying the opening and flatly attached to said outermost flap and supporting the handle end portions at the side of said first sheet furthest from the outermost flap. There are windows in the first closure sheet through which the handle passes.
