Document Type and Number:
WIPO Patent Application WO2001034410
Kind Code:
A8
Abstract:
A chalk box for producing a chalk line without leakage of chalk dust from within. The chalk box has a chalk-filled chamber that houses a spool (42) and a flexible chalk line (60). The chalk line (60) extends outwardly around a guidepost and through a tube (54). The tube (54) snugly hugs the flexible line (60), preventing chalk dust from leaking through the tube (54). The chalk dust impregnating the flexible line (60) provides lubrication for its passage through the tube (54). The present invention also includes a built-in pencil sharpener (48) isolated from the chalk dust, for the convenience of the user.
