ABSTRACT:
A writing instrument having a closure cap assembly (1, 2, 3, 4 and 5) which can be placed in a sealing manner on the writing tip (20), whereby a positive engagement with an indentation in the writing tip is established via an elastically deformable finger (8), when the closure cap is in place on the writing tip. On the inner face of the arm (8), oriented toward the writing tip (20), at least one cam face (13) is located in a chord plane of the circle forming the closure cap opening. Whereupon a twisting of the entire mounted closure cap assembly (1, 2, 3, 4 and 5) brings the cam face (13) into engagement with a correspondingly formed wedge face (27) of the writing tip (20), so that the arm (8) is pivoted radially outward, and the closure cap can be removed.
