Abstract
A chalk line device that includes a housing, a reel mounted for rotation within the housing, a liquid container disposed within the housing, and a handle connected with the reel and extending outside the housing is provided. The reel is constructed and arranged to carry a chalk line wound thereon. The reel is positioned in the liquid container such that the chalk line wound therein is at least partially submerged in the liquid chalk received in the liquid container. The liquid container has a sealed configuration and an unsealed configuration. In the unsealed configuration, the liquid container is configured to receive liquid chalk therein. In the sealed configuration, the liquid container substantially seals the liquid chalk received therein. The handle is operable to wind up the chalk line onto the reel.
