Patent attributes
A chalk box includes a housing with an opening and a rotatable reel disposed within the housing. An elongated line is arranged to be wound on the reel. A reel winder is arranged to rotate the reel to wind the line on the reel. A movable cover is mounted to the housing and is movable between an open position and a closed position, the cover when open permits a powder or a fluid marker material to be placed into the housing through the opening in the housing. The movable cover includes an elastomeric material enabling the cover to seal with the housing when the cover is closed to prevent leakage of the marker material at an interface between the movable cover and the housing. A releasable lock is arranged to releasably lock the cover in the closed position, the releasable lock being manually manipulable by a user's fingers to release the lock to permit access into the housing through the opening. The elastomeric material is overmolded onto and thus permanently connected to the relatively rigid material of the movable cover.
