Including Removable Cap For Tool Patents (Class 401/243)
  • Patent number: 5000603
    Abstract: A removable cap attached to a writing instrument in an insertion manner for preventing ink from evaporating from the writing instrument, comprises: a hollow cylindrical cap main body; and a hollow cylindrical inner cap fixedly mounted in the cap main body. The cap having been detached from the writing instrument permits open air to axially flow through the interior space of the cap through: a front axial opening of the cap; a ventilating hole of the inner cap; a space defined between the inner cap and the cap main body; and a clearance defined between a rear-end opening of the cap main body and a rear-end projecting portion of the inner cap, which projecting portion is disposed in the rear-end opening of the cap main body while space apart therefrom, whereby there is no fear that the cap suffocates infant's bronchi even if the infant swallows the cap whole.

  • Patent number: 4952088
    Abstract: To screw the writing tip in and out of the instrument shaft of a writing or drawing instrument, the cap has been used as a screwing tool. The cap is usually fabricated with a many-sided receiving bore for this purpose as an extension of its bore, which can be placed onto the writing tip after the cap has been turned around. As a result, the cap is relatively long. The writing or drawing instrument of the present invention in contrast, has a cap of standard length. A many-sided receiving bore which is to be placed on the writing tip, in order to be able to screw it in or out, is formed, in part, by the clip of the cap, and in part by the wall of cap in the region where the clip is connected to the cap.

  • Patent number: 4915529
    Abstract: A sealing cap for a writing, drawing or painting instrument includes an axially extending tubular member open at one end to receive the instrument. An interior space extends axially within the tubular member from the open end and is closed at the opposite end. An axially extending air channel, open at both ends, is located within tubular member. One open end of the air channel opens to an at least partially laterally closed space which is open outwardly from the closed end of the interior space. The other open end of the air channel is open to the interior space. The air channel does not interfere with the sealing effect of the interior space when an instrument is inserted into the space. Accordingly, whether the cap is fitted on the instrument or is removed from it, there is a continuous open path for the flow of air through the air channel.

    Abstract: An axially removable cylindrical holding shaft or cap for placement over and for unscrewing or removing the tip of a writing or drawing instrument, the holding shaft or a cap having a receiving bore for the instrument tip, and being comprised of at least one approximately axially extending lever which can be tilted about an axis extending approximately tangentially to the cylinder wall. The lever has an arm on each side of the axis. One of the arms forms part off the wall and has a detent at its end, the detent projecting into the receiving bore for engaging a groove or an undercut of the tip when the tip is inserted into the receiving bore, fixing the tip in the axial direction. The structure makes it possible to clean the adjustment system of the tip, avoiding the danger of getting it dirty, and without touching the tip while reinserting it into the housing.

  • Patent number: 4759651
    Abstract: The cap for the writing instrument comprises a jacket mounted slidably on a sealing insert or sleeve which provides a sealed moisture chamber for the writing tip when the cap is on the writing instrument. Near the writing tip there is a circular bulge on the shaft of the writing instrument which enters into a sealing engagement with an interior passage of the sealing insert. On putting the cap on the writing instrument the sealing insert is pushed over the circular bulge until it contacts a contacting stop on the jacket. Then the circular bulge presses tightly into the sealing insert and it locks the jacket to the writing instrument so that the entire arrangement is kept in that position until the cap is removed. A signal slider is attached with the sealing insert which is extendable out from the end of the jacket in order to signal in its extended position the proper seating of the cap on the writing instrument. Erroneous indications of a sealed state are prevented with our invention.
