  • Patent number: 4990012
    Abstract: In writing instruments having an ink or India ink reservoir, the reservoir should remain sealed prior to first use of the instrument. For this reason, the writing tip and the shaft containing the reservoir are delivered to the user separately. When the instrument is to be used for the first time, the writing tip is screwed into the shaft until the reservoir is pierced by the writing tip. The writing instrument of the invention enables delivery to the user in which the writing tip is already screwed into the shaft without piercing the reservoir. The writing tip has a removable separator piece which comes to rest at the front edge of the instrument shaft when the writing tip has been screwed in and thus limits the screw-in depth of the writing tip, the back end of the writing tip being maintained at a distance from the plug of the reservoir.
