Problems solved by technology

Current footwear covers introduce additional hazards to the wearer such as slipping and tripping as a result of excess material contacting the floor.
During use, current footwear covers can sag allowing material to drag on the floor creating a tripping hazard.
Typical areas in which such material commonly contacts the floor and creates a hazard include the ankle area and metatarsal area.
The patent does not teach the reduction of slipping and tripping hazards associated with the use of a shoe cover.

Embodiment Construction

[0018] This invention relates to a disposable footwear cover for use in sterile environments, medical facilities, industrial clean rooms and the like that employs elastic gathers and a non-slip coating to provide the wearer additional protection against slips, trips, and falls.

[0019] The disposable footwear cover of this invention is prepared from flexible sheet materials, having an inner surface toward the wearer's foot or footwear and an outer surface away from the wearer's foot or footwear, formed into the general shape of a shoe, boot, or foot. The flexible sheet materials can be woven or nonwoven. Preferably, the flexible sheet materials are nonwoven. The flexible sheet materials can optionally include a coating over part or all of the surface to provide additional functionality, such as providing barrier properties. Further, the flexible sheet materials can optionally include bicomponent fibers to provide additional functionality, such as stability to gamma radiation for ster...

Abstract

The present invention relates to disposable protective footwear covers suitable for use in sterile environments, critically controlled environments, medical facilities, and industrial clean rooms.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to disposable protective footwear covers suitable for use in sterile environments, critically controlled environments, medical facilities, and industrial clean rooms. [0003] 2. Description of Related Art [0004] Workers entering critically controlled areas need to don apparel to prevent substances released from the wearer's body from contaminating the environment. The apparel should not shed particles or fibers from the fabric. The apparel can further offer the worker protection from light liquid splash or dry particulates. [0005] Boot and shoe covers are important to prevent tracking particles throughout critically controlled areas. Disposable footwear covers are used in the semiconductor and life science industries to prevent product contamination and exposure of the wearer to hazardous pathogens or materials. [0006] Current footwear covers introduce additional hazards to the wearer su...
