Abstract
A marking instrument, such as a pen, is disclosed. The marking instrument includes a marking tip carried at the end of a tubular member for conducting marking fluid to the marking tip. The marking tip includes a tubular rear end section of circular cross-section. The tubular member is elliptical in cross-section and is attached to the tubular rear end section of the marking tip at an angle to the longitudinal axis of the tubular member. The elliptical shape of the tubular member allows for a circular profile opening when the tubular member is cut at an angle to join the tubular rear end section of the marking tip. Because the complementary profiles are circular in shape at the connection plane, it is not necessary to rotationally orient the components when bringing them together to be joined. The tubular rear end section of the marking tip may also be elliptical in shape, thereby requiring both the tubular rear end section and the tubular member to be cut at similar angles to produce the circular profile opening.
