Abstract
A slip resistant, disposable shoe cover with a body formed of a flexible, foldable, sheet material, the shoe cover comprising a bottom rib formed of a strip of flexible, stretchable, resilient, and slip resistant material. The bottom rib extends along and through a bottom seam of the shoe cover, and is at last partly exposed on the outside of the shoe cover. The bottom rib provides slip resistance, and it also serves to hold the shoe cover snugly over the wearer's shoe.

A slip-resistant disposable shoe cover comprising:
- (a) a foot-shaped body formed of flexible foldable sheet material, the body comprising an inside surface and an outside surface, the outside surface including a bottom having a bottom seam which runs longitudinally along the length of the bottom;
- (b) a bottom rib formed of a strip of flexible, stretchable, resilient, and slip-resistant material, the bottom rib having a stretched length and a relaxed length, the relaxed length being shorter than the length of the bottom seam, the bottom rib extending along and through the bottom seam, and being affixed to the bottom seam such that the bottom rib yieldably gathers the material of the bottom along the bottom seam, with the bottom rib being at least partly exposed on the outside of the cover along the bottom seam, and at least partly exposed on the inside of the body along the bottom seam.
A slip-resistant disposable shoe cover comprising:
- (a) a foot-shaped body formed of flexible foldable sheet material, the body comprising an inside surface and an outside surface, the outside surface including a bottom having a bottom seam which runs longitudinally along the length of the bottom;
- (b) a bottom rib formed of a strip of flexible, stretchable, resilient, and slip-resistant material, the bottom rib having a stretched length and a relaxed length, the relaxed length being shorter than the length of the bottom seam, the bottom rib extending along and through the bottom seam, and being affixed to the bottom seam such that the bottom rib yieldably gathers the material of the bottom along the bottom seam, with the bottom rib being at least partly exposed on the outside of the cover along the bottom seam.
A slip resistant disposable shoe cover comprising:
- (a) a body formed of flexible foldable sheet material, the body comprising an inside surface and an outside surface, the outside surface including a bottom having a bottom seam which runs longitudinally along the length of the bottom;
- (b) a bottom rib formed of rubber, the bottom rib being flexible, stretchable, resilient, and slip resistant, and having a stretched length and a relaxed length, the relaxed length being shorter than the length of the bottom seam, the bottom rib being between about 1/64 to about 1/4 inch in thickness, and between about 1/4 to about 11/2 inch in width, the bottom rib extending along and through the bottom seam, and being affixed to the bottom seam such that the bottom rib yieldably gathers the material of the bottom along the bottom seam, with the bottom rib being at least partly exposed on the outside of the cover along the bottom seam.
A method for forming a slip-resistant disposable shoe cover, the method comprising the steps of:
- (a) selecting a flexible foldable sheet material;
- (b) cutting a blank out of the sheet material, the blank being suitable for forming a shoe cover with a bottom having a bottom seam which runs longitudinally along the length of the bottom;
- (c) selecting a bottom rib comprising a strip of flexible, stretchable, resilient and slip-resistant material, the bottom rib having a stretched length and a relaxed length, the relaxed length being shorter than the length of the bottom seam to be formed out of the blank;
- (d) forming a shoe cover out of the blank, the shoe cover having an inside surface and an outside surface, the outside surface including a bottom with a bottom seam which runs longitudinally along the length of the bottom;
- with the bottom rib extending along and through the bottom seam, and being affixed to the bottom seam such that the bottom rib yieldably gathers the material of the bottom along the bottom seam, with the bottom rib being at least partly exposed on the outside of the cover along the bottom seam.
