Abstract
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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
118 words
A stand for a felt tip pen that is employed without a covering cap, comprising a container having a top, bottom, and at least one side wall, defining a hollow interior chamber, said top having at least one opening provided with a pen support, said pen support comprising a hollow, tubular shaft having a radially extending flange at its upper end, said flange being inflexible and firm about its outer periphery, and said tubular shaft being flexible and thin, allowing the felt tip of said pen to pass easily into said interior chamber and simultaneously engage the surface of said pen to enclose and seal that portion of the pen in said chamber from contact with ambient air.
