  • Marking instruments
    Patent number: 6328496
    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.

  • Marking instruments
    Patent number: 5676481
    Abstract: A marking instrument, e.g. a fiber tip pen, roller ball pen, or highlighter pen, has a feed device which conducts marking liquid from the reservoir chamber (17) to the marking tip supported by an elastomeric diaphragm (6) which partly confines the reservoir chamber and forms a valve with the feed device so that when tip is applied against a surface the feed device retracts causing the diaphragm (6) to pressurize the liquid in the reservoir and open the valve whereby liquid is pumped to the tip.
