An improved marker for applying a writing material to
- a surface comprising;
- a barrel having a reservoir for containing a writing material;
- a marker body connected to said barrel member, said barrel having at least one open end, said marker body being generically cylindrical and having an inside wall, and an outside wall, said inside wall having a a conical projection extending from said inside wall of said marker body, said conical projection having an inner surface and an outer surface;
- a stem member having a plug portion and a stem projection, said plug portion having an open end and a closed end with a generally cylindrical side wall between said ends, said open end of said stem having an outer circumferential surface and an inner circumferential surface at said open end, said inner circumferential surface being in a sealing engagement with said outer surface of said conical projection when said plug portion contacts said conical projection of said marker body and an open position when said plug portion is away from said conical projection;
- a resilient member for biasing said stem member into sealing engagement with said conical projection of said marker body for the purposes of controlling the flow of said writing material from said barrel into said marker body.
