Abstract
A marking instrument includes a barrel, a marking tip and a marking fluid reservoir disposed in the barrel, a retraction mechanism to move the marking tip from an operable position to a retracted position through an opening in the barrel, and a seal to close off the marking tip from the barrel opening when the marking tip is retracted. The seal is toroidal in shape, which allows the seal to close upon itself, thereby eliminating any need for additional manipulation or outside forces to close the seal. The marking tip, marking fluid reservoir and seal are replaceable so that each can be replaced when they become worn or inoperable.
