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: A correction fluid that prevents clogging of the delivery nib of a correction fluid marker separates into liquid and solid phases while not in use, thereby allowing the liquid phase to transport lubricants and anti-oxidants into the nib between uses to restore and preserve the nib. The correction fluid includes a thixotropic gel that soft settles and creates a gelatinized long lasting network of hydrogen bonded fibers in the formulation which are rejuvenated by shaking of the applicator and which do not appreciably agglomerate over time. The correction fluid further includes weak solvents and mild resins which advantageously do not swell the nib fibers or destroy the adhesives in the nib over time. A correction fluid marker 10 for applying the correction fluid includes a hollow barrel 12 having an interior reservoir 18 for holding the correction fluid, and a porous nib 20 held in a sleeve 22 at one end of the barrel in communication with the reservoir.

Abstract: A fountain brush includes a reservoir serving as a handle. A one-piece valve body fixed in the neck of the reservoir contains a gravity-activated applicator brush holder which is shiftable within the valve body between liquid applying and non-applying positions. Valve elements on the opposite ends of the brush holder engage cooperative seats of the one-piece valve body in the liquid applying and non-applying positions of the brush holder.
