Abstract

A fabric stain treatment device for treating a stain on a fabric with a fabric stain treatment composition during a fabric washing process, the fabric stain treatment device comprising: (a) a storage chamber for storing the fabric stain treatment composition, said storage chamber comprising two adjacent convex walls in a stacked arrangement with an upper wall and an lower wall; and a waist portion; (b) a filling and dispensing aperture defined by one or more upper edge portions of the storage chamber, said edge portion/s comprising a pour spout; and (c) a base the periphery of which is contiguous with the lower wall; said base and lower wall interconnecting at a base edge portion at least one annular scrubbing portion on a base edge portion.

First claim

The invention claimed is:

1. A fabric stain treatment device for treating a stain on a fabric with a fabric stain treatment composition during a fabric washing process, the fabric stain treatment device comprising:
a storage chamber for storing the fabric stain treatment composition, the storage chamber comprising:
two adjacent convex walls in a stacked arrangement with an upper wall and a lower wall;
a waist portion;
a top surface; and
an upper edge portion protruding from the top surface;

a filling and dispensing aperture disposed on the top surface and circumscribed by the upper edge portion;
a pour spout defined by the upper edge portion and configured to receive the fabric stain treatment composition from the filling and dispensing aperture;
a base comprising a periphery which is contiguous with the lower wall, the base and lower wall interconnecting at a base edge portion; and
an annular scrubbing portion contiguous with the base edge portion;
wherein the upper edge portion and the top surface are configured to cooperate to collect the fabric stain treatment composition from the filling and dispensing aperture and direct the fabric stain treatment composition to the pour spout.

2. The device of claim 1 , wherein the upper and lower walls have a substantially common convex curvature.

3. The device of claim 1 , wherein the adjacent walls converge to co-join each other thereby defining a curved cleft indentation in at least the outer surface of the storage chamber thereby providing the waist portion.

4. The device of claim 1 , wherein the storage chamber comprises an inner surface of the fabric stain treatment device which mirrors the outer surface and there is at least one internally projecting edge portion provided by the cleft.

5. The device of claim 1 , wherein the base comprises a central concave portion.

6. The device of claim 1 , further comprising a unit dose of the fabric stain treatment composition.

7. The device of claim 1 , wherein the fabric stain treatment composition comprises one or more enzymes.

8. The device of claim 7 , wherein the one or more enzymes comprises a pectate lyase enzyme.

9. The device of claim 7 , wherein the one or more enzymes further comprises one or more enzymes selected from: protease, lipase, phospholipase, amylase, cutinase, cellulose, mannanase, peroxidise, and oxidase.

10. A process for treating fabric stains with a fabric stain treatment composition during a fabric washing process comprising the steps of:
(a) charging with the fabric stain treatment composition, the stain treatment device according to claim 1 ;
(b) pouring at least a portion of the fabric stain treatment composition from the stain treatment device on to a fabric stain via the pour spout;
(c) holding the stain treatment device at the waist portion and scrubbing the fabric with the annular scrubbing portion and then optionally,
(d) placing the device and the remaining composition and the fabric into a washing machine to undergo a washing process therein.

11. A process according to claim 10 comprising the step of tilting the stain treatment device prior to and/or during the step (c) of scrubbing the fabric.

12. A fabric stain treatment kit comprising:
(a) a fabric stain treatment composition comprising one or more enzymes;
(b) a fabric stain treatment deice comprising:
a storage chamber for storing the fabric stain treatment composition, the storage chamber comprising:
two adjacent convex walls in a stacked arrangement with an upper wall and a lower wall;
a waist portion;
a top surface; and
an upper edge portion protruding from the top surface;

a filling and dispensing aperture disposed on the top surface and circumscribed by the upper edge portion;
a pour spout defined by the upper edge portion and configured to receive the fabric stain treatment composition from the filling and dispensing aperture;
a base comprising a periphery which is contiguous with the lower wall, the base and lower wall interconnecting at a base edge portion; and
an annular scrubbing portion contiguous with the base edge portion;
wherein the upper edge portion and the top surface are configured to cooperate to collect the fabric stain treatment composition from the filling and dispensing aperture and direct the fabric stain treatment composition to the pour spout; and
(c) instructions to treat a fabric stain using the device and the composition, the instructions including the steps of:
charging the device with the composition;
pouring at least a portion of the composition from the device on to a fabric stain via the pour spout;
holding the device at the waist portion and scrubbing the fabric with the annular scrubbing portion and then optionally,
placing the device and the remaining composition and the fabric into a washing machine to undergo a washing process therein.
