Abstract: A writing utensil has a container for receiving temporarily a writing liquid oversupplied from a reservoir. A plurality of liquid staying pieces are formed on the outer periphery of the container in layers at a regular distance. A liquid supplying passage is formed along the central axis of the container. A through-hole is formed at a wall of the container for communicating a space formed by the staying pieces with the supplying passage. Upward guiding slits are formed vertically in a straight line at the staying pieces. A tension generating space is formed on the outer periphery of the container diametrically opposite to the upward guiding slits. A pair of downward guiding protrusions are formed longitudinally in the tension generating space and provide a downward guiding groove therebetween. A downward guiding slit is formed at the uppermost staying piece while being aligned with the downward guiding groove.

Abstract: The writing instrument having an excellent cap-off performance is characterized, as shown in, for example, FIG. 3, by that in a writing instrument 10 having a pen tip 13 comprising a fibrous feed or a plastic feed, the pen tip 13 described above is coated with a substance which is solid at room temperature and in which a solubility in an ink solvent is 10% or less at room temperature among substances providing the pen tip with a cap-off property. This writing instrument 10 is such excellent in a cap-off performance that the good writing performance is obtained even after the pen tip is left standing in the air over a long period of time.

Abstract: The present provides a porous plug between a reservoir and a feeder having an open space therein to store the excess liquid as the underpressure within the reservoir subsides, i.e., higher absolute pressure. That is, as excess liquid conveys through the porous plug and then to the feeder, liquid take the path of least resistance, which in this case is the open space within the feeder. As liquid enters the open space, air within the open space is displaced through larger capillaries in the feeder. The displacement of air creates an slight vacuum or underpressure within the open space itself to hold the liquid inside the open space until the underpressure within the open space rises, i.e., lower absolute pressure.

Abstract: An optical fiber cleaner includes a base having a well supported within an annular section. An absorbent material, such as a sponge or cotton ball, may be located within the well of the base. A cover mates with the base and holds a wipe in a preferred position over the well.

The cover may also include a hinged element, or lid, that closes over the aperture within the cover when the cleaner is not in use. The base may itself be an element of the lid of a push-pump mechanism. In such case, the well within the base is operationally connected to receive solvents from the pumping mechanism and the pumping mechanism, including the base, forms a cover for a solvent reservoir, such as a non-reactive bottle.

A closure cap for the pen is formed with large openings in the region surrounding the color coded nib, to provide visual access to the colored nib when the cap is mounted on the pen body. An air passage, necessary for the reservoir of the pen to “breath”, is extended to have its outlet immediately adjacent the writing tip of the pen, and the closure cap is provided with an internal sealing cup at its closed end, which is received over the writing tip and closely adjacent portions of the nib, to seal both the writing tip and the air passage, when the closure cap is in place.

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.

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 capillary writing medium colorant reservoir system for a writing instrument and process for producing the colorant reservoir. The main problem in such colorant reservoirs is the storage time. During this time, the writing capacity of new writing instruments declines since the walls of the writing instruments are, if only slightly, permeable to solvents. In the long run a stored writing instrument thus dries out and loses the major proportion of its original writing capacity. To this end, the invention has a colorant reservoir with an elongated reservoir body made of fibrous material. The reservoir body is surrounded by a sleeve which is permeable to liquids and gases and gives the reservoir body its shape. The reservoir stores colorant to produce liquid writing medium, the colorant being stored between the fibers of the fibrous material of the reservoir body in dry form. A single-part or multipart wick projects from either side of the reservoir body.
