Patent number: 6572297Abstract: A liquid marker system utilizes three primary components to permit marking of lines of various widths from a single nib. The three components are a porous nib, a transfer wick and a squeezable container. Operation relies on different squeeze pressures applied to the housing to produce different line widths from the single nib as the nib is moved across a marked surface. The porous wick provides a resistance to flow until the bottle is squeezed and then supplies a minimum of capillary flow to the nib. The user squeezes the container to overcome the resistance of the wick. No venting of the container interior is required because the wick and nib system allows the passage of air into the container when the container is returned to its unstressed (i.e., un-squeezed) condition.Type: GrantFiled: May 2, 2002Date of Patent: June 3, 2003Inventor: George W.
