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 pre-spotter to the detergent user at the time of laundering. The invention also concerns methods of use of such products during laundering.

Claims

1. In the method of laundering fabric, the steps that include:

(a) providing a first volume of detergent a portion of which is to be added to fabric laundry wash water,

(b) providing a second and smaller volume of a prespotter composition in close transported association with said first volume of detergent for presentation at the time of laundering,

(c) and separating some of said prespotter composition from said close association with the detergent volume and applying same to a soiled portion or portions of fabric that is thereafter laundered in said wash water containing said added portion of detergent,

(d) said first volume of detergent being provided in a relatively large container, provided with a neck,

(e) said prespotter composition being provided in a fitment substantially smaller than said relatively large container,

(f) said (b) step including locating the fitment in the relatively large container, via said neck,

(g) and gaining access to the fitment in the large container and via said neck so that prespotter composition may be dispensed, and at the time of also gaining access to the detergent in the large container, via said neck prior to said step (c) application.

2. The method of claim 1 including:

(i) providing said neck at the top of said relatively large container containing said first volume of detergent,

(ii) providing a sub-container containing said smaller volume of prespotter composition, and

(iii) mounting said sub-container on said neck in close transported association with said container.

3. The method of claim 2 wherein said (iii) step includes mounting the sub-container in transported relation to the container as defined in claim 1, for presentation to the user of the detergent at the time of laundering.

4. The method of claim 1 including incorporating beads admixed with the detergent and 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, each bead comprising

(a) a porous substrate,

(b) and substance absorbed into said substrate to produce at least one of said (i) and (ii) properties in the fabric.

5. The method of claim 4 including a barrier layer formed about said bead substrate and absorbed substance and characterized as dispensing in laundry wash water, and allowing said barrier layer to so disperse in the wash water.

6. The method of claim 5 wherein the bead substrate is selected from the group that consists of puffed borax, dendritic salt, and clay.

7. The method of claim 5 including a solubilizing or dispersion aid mixed with said substance and also absorbed into the the bead substrate.

8. The method of claim 5 including a hardener mixed with said substance and also absorbed into the bead substrate.

9. The method of claim 7 including a hardener mixed with said substance and aid, and also absorbed into the bead substrate.

10. The method of claim 6 wherein said substance is cationic.

11. The method of claim 6 wherein said substance comprises a material selected from the group consisting of quaternary ammonium compounds and imidazolinimum compounds.

12. The method of claim 7 wherein said solubilizing or dispersion aid is selected from the group consisting of

(x₁) ampholytic surfactants which contain both anionic and cationic moieties,

(x₂) Zwitterionic surfactants which also contain both anionic and cationic moieties,

(x₃) fatty acid soap.

13. The method of claim 5 wherein said barrier layer is water soluble and is selected from the group that includes amorphous silica, inorganic salts, starch and powdered dyes.

14. The method of claim 4 wherein between about 1% and 90% of the bead weight is defined by the substrate and between about 5.0% and 75% of the bead weight is defined by said substance.

15. The method of claim 9 wherein between 1% and 90% of the bead weight is defined by the substrate and between about 0.5% and 75% of the bead weight is defined by said substance, and said mix consists of from about 1% to 100% by weight of said substance, from about 1% to 100% by weight of said solubilizing or dispersion aid, and from about 0.1% to 100% by weight of said hardener.

16. The method of claim 14 including from about 1% to about 30% by weight of a barrier layer in finely divided solid form extending about said substrate and absorbed substance and characterized as dispersing in laundry wash water.

17. The method of claim 15 including from about 1% to about 30% by weight of a barrier layer in finely divided solid form extending about said substrate and absorbed substance and characterized as dispersing in laundry wash water.

18. The method of any one of claims 4-17 wherein multiple beads as defined are admixed with dry laundry detergent.

19. The method of claim 1 including providing said container with a transparent wall via which said fitment can be seen in the container neck from the exterior.

20. The method of claim 1 including (d) adding said detergent portion and fabric to the wash water in a washing machine and initiating operation of said machine to launder the fabric, said (c) step carried out just prior to said addition of the fabric to the wash water.
