  • Patent number: 5033629
    Abstract: A desk type stand for a felt tip pen that is employed without a cover. The pen stand has a hollow container having an opening at its upper surface for receiving an appropriate felt tip pen. A pen support is disposed in the opening in the container. The support is made of elastomeric or rubber material which is inflexible and firm about its outer periphery and flexible and thin at an opening at its center, allowing the felt tip of the pen to move through the doughnut-shaped insert into the container after which the flexible portion of the insert or washer seals the felt tip in the container out of contact with the ambient air.
