Tumble dryer dispenser
View Patent ↗A device for treating fabrics in a tumble dryer comprising a reservoir for storing a fabric treatment composition and transfer device to expose fabric treatment composition from the reservoir to airflow generated inside the tumble drier and/or to directly contact fabrics in the dryer, thereby transferring a portion of the fabric treatment composition into contact with fabrics in the tumble dryer during a tumble drying cycle; characterised in that the transfer device comprises compressed foam.
1. A device for treating fabrics in a tumble dryer comprising a reservoir for storing a fabric treatment composition and transfer means to expose fabric treatment composition from the reservoir to airflow generated inside the tumble drier and/or to directly contact fabrics in the dryer, thereby transferring a portion of the fabric treatment composition into contact with fabrics in the tumble dryer during a tumble drying cycle; characterised in that the transfer means comprises compressed foam having a compression ratio of 8 or more and an inner flow control member comprising a membrane, the compressed foam being downstream from the inner flow control member and functioning to reduce staining when contacting fabrics.
2. A device according to claim 1 wherein the compressed foam is in the form of one or more layers.
3. A device according to claim 1 wherein the foam is compressed prior to fitting in the device.
4. A device according to claim 1 wherein the compressed foam is a polyurethane foam.
5. A device according to claim 1 the compressed foam is a polyester foam.
6. A device according to claim 1 where the compression ratio is 10 or more.
7. A device according to claim 1 wherein the compression ratio is 12.
8. A device according to claim 1 wherein the compression ration is 14.
9. A device according to claim 1 wherein the initial (pre-compression) pore size of the foam is 120 or less.
10. A device according to claim 1 wherein the initial (pre-compression) pore size of the foam is 100 or less.
11. A device according to claim 1 wherein the initial (pre-compression) pore size of the foam is 80 or less.
12. A device according to claim 1 wherein the initial (pre-compression) pore size of the foam is 60 or less.
13. A method of treating fabrics in a tumble dryer during multiple tumble drying cycles comprising attaching a device according claim 1 to the inside of a tumble dryer door and carrying out a tumble drying process with fabrics inside the tumble dryer.
14. A method according to claim 13 in which the tumble drier is operated to achieve an elevated temperature of up to 100° C.
15. A kit comprising a device according to claim 1 in combination with a fabric treatment composition optionally provided in a reservoir for use with said device.
16. A device according to claim 1 wherein the inner flow control member is a polypropylene membrane.
