Abstract: Unique dental floss article comprising islands attached to the underlying surface of dental floss for dislodging plaque and oral debris during use. These unique structures exhibit superior retention of the drag resistance during flossing.

Abstract: The present invention is a simulated stone structure having a base with an upfacing planar surface and a continuous groove formed in the surface. A plurality of mutually interlocking wall sections are engaged with the groove to form a continuous wall extending upwardly from the planar surface. The wall sections may be U-shaped with one leg in the groove and the other in contact with the periphery of the base. The wall sections partially overlap each other. s an abutting one of the wall sections. Additional wall sections may be placed atop the first set and interlocked with them. A topper piece may be placed on the additional wall sections for securement thereof.

Abstract: In a preferred embodiment, the invention is a non-deflatable tire assembly having a hollow toroid-shaped flanged insert, a flexible body molded around the insert to form a tire, and at least one rim onto which is mounted the tire. The flange of the insert extends toward the central axis of the insert, and is used to attach the tire to the rim(s) via bolts through matching holes within the flange and rim(s). The flexible body may be made of a foam polyurethane matrix formed of a combination of polyol and polyisocyanate, while the flanged insert may be made of a high density polyethylene. A tough, flexible, and abrasive-resistant layer of polyurethane elastomer is preferably formed around the flexible body to define sidewalls and treads of the tire.

Abstract: A lockable zipper closure includes at least one slider with a pulling tab that has an opening therein, and means such as a T-shaped column for locking the zipper in the closed position, that is movable from a position in which the column may pass through the opening to a position in which the column will not pass through the opening, and means for locking the column in the position where the column cannot pass through the opening.

Abstract: A pair of molded plastic covers are connected along one side by a hinge, and a plurality of cards are removably mounted in an overlapping relationship on the interior surface of each of said covers. The hinge comprises a post secured in a spaced relationship from an edge of each of the covers, and a double barrel member journalled on and hingedly connecting the respective posts. The surfaces on which the cards are mounted are molded with a concave configuration to allow the overlapping cards to lie flat. The cards are mounted on wire hangers which project into spaced grooves on the mounting surface.
