Abstract

A chalk port for retaining chalk within a chalk reservoir of a chalk box may include an interface portion configured to interface with a housing of the chalk box to retain the chalk port in contact with the chalk box, a tapered portion extending away from the interface portion in an axial direction, and a slit assembly disposed at the tapered portion. The tapered portion may have a diameter that reduces as distance from the interface portion increases. The tapered portion may include a plurality of projections separated from each other by slits of the slit assembly. The projections may have a rest position configured to bias the slit assembly closed. Ribs may be formed to extend between the interface portion and the projections to bias the projections to the rest position.
