US 6,684,440 B1 · Three dimensional fabric care bag that resists collapsing during use

Abstract

A vapor-venting containment bag having at least three flexible side walls and a VVE rating of at least about 40 and less than about 90, as measured in the Vapor Venting Evaluation Test. When the bag is in its closed configuration a three dimensional interior void space is formed whereby the bag resists collapsing. Also, a fabric cleaning and refreshment process that is conducted in a hot air clothes dryer using the vapor-releasing containment bag. The bag is constructed using heat resistant polymers, such as nylon. The bag retains its integrity and can be re-used in subsequent dry cleaning operations. Vapor is vented from the bag during use, thereby minimizing wrinkling in the clothes being cleaned and removing malodors therefrom.

Dependent claims

A vapor-venting containment bag comprising a bag material having one or more fold lines inscribed thereon, an opening and a fastening means for closing the bag, wherein the bag comprises:

i) a folded configuration when the bag material is folded along one or more of the fold lines;
ii) a closed configuration when the bag material is in its folded configuration and the fastening means substantially closes the opening, thereby the bag defines a three dimensional interior void space;
and
iii) a VVE rating of from about 40 to about 90, as measured in the Vapor Venting Evaluation Test.
