Fabric bag for use in fabric care processes
View Patent ↗The present invention relates to improved bag-type containers for use in a non-immersion fabric care process for dry clean only fabrics. The outer shell of the bags are made from fabric such that the bags resist melting at higher temperatures than conventional non-fabric plastic bags and/or the bags are more pliable and/or supple than conventional non-fabric plastic bags and/or the bags retain more of their pliability and/or suppleness than conventional non-fabric plastic bags after being subjected to heat and/or the bags produce less noise during use than the conventional non-fabric plastic bags and/or the bags retain their shape and/or resist wrinkling during use better than the conventional non-fabric plastic bags. The bags of this invention are used in fabric care or “refreshment” processes are conducted in a hot air environment, preferably dryers, in the presence of a cleaning/refreshment composition.
1. A vapor-venting fabric containment bag comprising:
i) an open configuration and a closed configuration;
ii) a VVE rating of at least about 40 and less than about 90, as measured in the Vapor Venting Evaluation Test; and
wherein when the bag is in its closed configuration the bag comprises at least three flexible side walls and a three dimensional interior void space is formed whereby the bag resists collapsing.
2. The bag according to claim 1 which has a VVE rating of at least about 60 and less than about 90.
3. The bag according to claim 1 which has a VVE rating of at least about 60 and no greater than about 80.
4. The bag according to claim 1 which is formed from fabric which is heat resistant up to at least about 260° C.
5. The bag according to claim 1 which is formed from polyethylene terephthalate or nylon.
6. The bag according to claim 1 further comprising a first fastening device and a second fastening device, which together form a mechanical fastener.
7. The bag according to claim 1 further comprising a first fastening device and a second fastening device, which together form an adhesive fastener.
8. The bag according to claim 1 which comprises at least four side walls configured in the form of a tetrahedron.
9. The bag according to claim 1 which comprises at least six side walls configured in the form of a cube.
10. A process for cleaning or refreshing a fabric article by adding to a vapor-venting fabric containment bag according to claim 1 a fabric cleaning/refreshment composition comprising water and the fabric article to be cleaned or refreshed.
11. The process according to claim 10 which is carried out in a hot air clothes dryer at a temperature from about 40° C. to about 150° C., whereby malodors present on the fabric article are vented from the bag by means of a vapor-venting closure.
12. A kit for cleaning or refreshing a fabric article, comprising a package containing:
(a) one or more absorbent articles comprising a carrier which releasably contains water and optional non-water fabric cleaning/refreshment ingredients; and
(b) a vapor-venting fabric containment bag according to claim 1 .
13. The kit according to claim 12 further comprising from one to about ten of the absorbent articles which are disposable after a single use.
14. A process for cleaning or refreshing a fabric article by adding to the fabric bag of claim 1 a fabric cleaning/refreshment composition comprising water and the fabric article to be cleaned or refreshed.
15. The process according to claim 14 which is carried out in a hot air clothes dryer at a temperature from about 40° C. to about 150° C., whereby malodors present on the fabric article are vented from the bag by means of a vapor-venting closure.
16. A kit for cleaning or refreshing a fabric article, comprising a package containing:
(a) one or more absorbent articles comprising a carrier which releasably contains water and optional non-water fabric cleaning/refreshment ingredients; and
(b) the fabric containment bag of claim 1 .
17. The kit according to claim 16 further comprising from one to about ten of the absorbent articles which are disposable after a single use.
18. The kit according to claim 16 further comprising instructions for using the fabric bag and one or more absorbent articles to clean and/or refresh a fabric article, the instructions comprising the following steps:
(a) place the fabric article to be cleaned and/or refreshed into the fabric bag;
(b) place one or more absorbent articles into the fabric bag;
(c) place the fabric bag containing the fabric article and one or more absorbent articles into an automatic clothes dryer; and
(d) operating the automatic clothes dryer such that the fabric article is cleaned and/or refreshed.
