Abstract: 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.

Abstract: Apparatuses using gel ink to create images, particularly, generally pen shaped stampers and markers, wherein gel ink of various types are used.

All three components are made of a porous material that will absorb the gel ink. The apparatus using gel ink for creating images can then be used to stamp or to draw on a surface.

Abstract: One feature of the present invention is to provide a capillary hole through a storage container that is holding the liquid so that as the underpressure within the container increases, atmospheric air may enter through the capillary hole to hold the underpressure at a predetermined level. One of the advantages with the present invention is that air enters through the container wall and not through the conveying line. That is, the diameter of the capillary hole formed in the container may be more precisely controlled than trying to control the largest pore size in the conveying line. This means that the performance of the writing instrument may be held to a tighter tolerance because the underpressure in the container may be more accurately controlled.

Each ink feeder includes a center core for feeding ink to the writing point. Air is inhibited from flowing into the ink tank through the ink collector air/liquid exchanger located at one end while the pen is being used for writing at the opposite end.
