A blood collection container is coated on its inside wall with a unitarily immobilized clotting activator. The activator may be applied to the surface by an adhesive or by rendering the inside wall surface sticky with a solvent and partially absorbing the activator into the sticky surface.

The foot smoothing pad has a polyurethane foamed core which is coated with particulate abrasive material. The pad is water resistant and completely washable and may be used either wet or dry. It is used to remove buildup of rough, dry skin, especially on the feet and hands. The soft and resilient texture of the pad insures comfort and ease in smoothing the skin. The large inside curved surfaces are used to smooth the heels, and the rounded sides may be used for smaller areas, such as the toes.

A sanding block includes a compressible core having at least one pair of sides characterized such that an abrasive material is adhered to said sides substantially along the surface thereof and having a juncture area defined between said two sides which does not have said abrasive material adhered thereto such that the abrasive material does not run continuously about the sides of the core thereby providing the two sides to be readily compressed toward one another. A method of forming the same is also provided.

A sanding block comprising slideably interrelated parts for accommodating an endless sanding belt and having a dual action means for selectively moving the parts into bearing relation with the sanding belt for maintaining tension thereon or moving the parts out of such bearing relation with the sanding belt for facilitating removal or adjustment of the sanding belt relative to the sanding block, while also providing the sanding block with a novel convexly curved surface for improved tool versatility.

A disposable sanding device is fabricated as a continuous rope-like article which is adapted for selective segmentation and application as a plurality of serially arranged disposable hand sanding devices or ropes. Each hand sanding device is formed as a generally elongated rod shaped base portion formed of lightweight material such as closed cell foam having a relatively constant cross-section along its line of elongation. An abrasive surface is permanently applied to the external surface of the base portion via an intermediate adhesive layer. As constructed, the sanding device is operable to conform to curvilinear contours of a work piece to be sanded upon application of user induced loading against the work piece. A dispenser holds a rolled length of sanding rope and includes a cutter feature for severing pieces of sanding rope from the coil as required as well as a retainer for the free end of the coil. A tensioning hand tool holds a severed length of sanding rope for precise applications.
