发明名称 STACKABLE CHALK HOLDER
摘要 A support for writing material comprising a hollow casing having open upper and lower ends. A plurality of holders for writing material, such as sidewalk chalk, are releasably, frictionally and moveably disposed in a stack in the hollow casing, wherein each holder is adapted to removeably and securely hold a piece of writing material in a first partition of each holder. Each holder also has a second partition separated from the first partition, said second partition providing a hollow volume adapted to receive the writing material held by a lower adjacent holder. Each holder may hold writing material of the same color, or of varying colors. By applying finger pressure to the hollow lower partition of the lowermost holder in the casing, the writing material in the uppermost holder is frictionally advanced beyond the upper open end of the casing, and the writing material is applied by the user to a sidewalk or other selected surface.
