Abstract

Portable stain removal kit ( 1 ) for locally removing a stained area on a fabric comprising a container ( 4 ) for containing a stain removing material ( 5 ) in a solid form, the container ( 4 ) being intended to be in direct contact with the stained area when the portable stain removal kit ( 1 ) is in use, whereby said portable stain removal kit ( 1 ) also comprises a base holder ( 3 ) for holding the container ( 4 ), and a cover ( 2 ) cooperating with the base holder ( 3 ) for enclosing the container ( 4 ) when the portable stain removal kit ( 1 ) is not in use.

First claim

The invention claimed is:

1. A portable stain removal kit for locally removing a stained area on a fabric, comprising:
a container containing a stain removing material, the stain removing material being in a solid form, the container having an upper surface for being in direct contact with an underside fabric surface of the stained area when the portable stain removal kit is in use,
a base holder having a liquid receiving portion, wherein the base holder supports and holds the container within the liquid receiving portion via a lower surface of the liquid receiving portion, wherein a top surface of lateral edges of the liquid receiving portion and a portion of the upper surface of the container are aligned with one another, and
a cover that cooperates with the base holder for enclosing the container within the liquid receiving portion of the base holder when the portable stain removal kit is not in use, and for uncovering the container within the liquid receiving portion of the base holder when the portable stain removal kit is in use,
wherein the container is fluid-permeable, so to allow steam and/or water to enter/penetrate the container to react with the stain removing material in the container in order to produce a chemical solution, and
wherein the liquid receiving portion supports and holds the container from underneath, via the lower surface of the liquid receiving portion, when the stain removing material of the container is in use for locally removing the stained area on the fabric.

2. The portable stain removal kit according to claim 1 , wherein the stain removing material comprises an active oxygen source.

3. The portable stain removal kit according to claim 2 , wherein the active oxygen source comprises any one of hydrogen peroxides with formula H 2 O 2 ; sodium percarbonate with formula Na 2 CO 3 .1.5H 2 O 2 , and sodium perborate with formula NaBO 3 .H 2 O or NaBO 3 .4H 2 O.

4. The portable stain removal kit according to claim 1 , wherein the stain removal material further comprises a bleach activator.

5. The portable stain removal kit according to claim 4 , wherein the bleach activator comprises any one of:
tetraacetylethylenediamine (TAED),
4-decanoyloxybenzoic acid (DOBA),
sodium salt of nonanoyloxybenzenesulphonic acid (NOBS),
sodium salt of 3,5,5-trimethylhexanoyloxyphenylsulfonic acid (iso-NOBS),
sodium salt of acetoxyphenylsulfonate,
sodium decanoyloxybenzene sulfonic acid (DOBS),
sodium octanoyloxybenzene sulfonic acid (OOBS),
sodium nonanoyloxybenzoic acid (NOBA),
N,N-Diacetylethylenediamine,
N-[4-(triethylammoniomethyl) benzoyl]butyrolactamchloride (TBBC),
sodium trimethylhexanoyloxybenzenesulfonate (STHOBS),
sodium-4-benzoyloxybenzenesulfonate (SBOBS),
glucose pentaacetate (GPA),
tetraacetylglucoluril (TAGU),
nitrilotriacetate (NTA),
transition metal bleach catalyst.

6. The portable stain removal kit according to claim 1 , wherein the container takes any of the forms defined by a bag, a pad, a cartridge, a sachet, and a capsule.

7. The portable stain removal kit according to claim 1 , wherein the container is made of a material taken from any one of high density paper, fabric, non-woven fabric, and porous plastic.

8. The portable stain removal kit according to claim 1 , wherein the container further comprises fragrance and/or perfume agents.

9. The stain removal kit according to claim 1 , wherein the container is divided into at least two compartments for storing different stain removing materials.

10. The portable stain removal kit according to claim 1 , wherein the base holder and/or the cover are fluid-impermeable.

11. The portable stain removal kit according to claim 1 , further comprising:
a liquid tank for containing water and/or a chemical neutralizer, and
a dispensing mechanism for dispensing said water and/or chemical neutralizer from the liquid tank to the stained area.

12. The portable stain removal kit according to claim 11 , wherein the dispensing mechanism corresponds to any one of a pressure based nozzle, a velocity based nozzle, a spray, and dripping by gravity.

13. A method of removing a stained area using a portable stain removal kit according to claim 1 comprising:
removing the cover for exposing the container,
locating the portable stain removal kit under the fabric to allow direct contact between the container and the underside fabric surface of the stained area, and
applying water and/or steam and/or heat to the stained area.

14. The method as claimed in claim 13 , wherein the portable stain removal kit further comprises:
a liquid tank for containing water and/or a chemical neutralizer, and
a dispensing mechanism for dispensing said water and/or chemical neutralizer from the liquid tank to the stained area;

the method further comprising the step of:
using the dispensing mechanism for dispensing water and/or chemical neutralizer from the liquid tank onto the stained area.
