  • Patent number: 5323897
    Abstract: A portable enclosure for the placement of wet articles for storage and at least partial drying. The enclosure includes a rigid plastic frame including an article hanger enclosed by a housing with a top, bottom and sides. At least three of the sides and the top are at least partially formed of a mesh material and at least the bottom is impervious. An exteriorly extending adjustable length strap with Velcro type closure means attached to the frame can be looped over an external support to support the enclosure and contents. A container is located in the bottom of the housing to catch any liquid dripping from the wet articles to contain the dripping within the housing. A zippered opening in one wall is provided for selected entry into the interior of the housing.
