  • Patent number: 6152634
    Abstract: A writing instrument having a sanitary moistener comprises an elongated body having a writing tip at one end and a supply of moistening liquid accessible at a location on the body of the instrument by a finger of an individual using the instrument, in order to moisten the finger to facilitate turning sheets of paper. The moistening liquid is supplied in a reservoir and delivered by a pump, or through a finger-operated valve. Alternatively, the moistening liquid is supplied in a liquid retaining porous medium having a part which can be exposed through an opening in the body of the instrument. In one embodiment, the liquid-retaining medium is accessible at the end of the instrument opposite to the writing tip. In two embodiments, the liquid-retaining moistener has conical passages receiving the ink cartridge and a side projection received in an open-ended slot in one of two parts constituting the body of the instrument.

    Abstract: A writing instrument comprises a combined marking pen and a fine line pen, especially useful for providing a highlighter and an underliner or a note writer. It comprises a single elongated body (23) with a felt marking pen tip (25A) and a ballpoint pen tip (27A), both projecting from the bottom end of the body. The ends of the tips are spaced apart in the longitudinal direction of the body and in a second direction perpendicular to the longitudinal direction. This enables a user to write with either tip by holding the pen at either of two angles to the vertical. The spacing in the second direction can be effected, even if the felt body and the ballpoint cartridge are adjoining, by providing a cutout (24) in the felt tip adjacent the ball point tip. The pen can include two ballpoint tips (57A, 57B), spaced from the marker's tip in the second direction, but aligned in the longitudinal direction. The body can include a dividing partition (64) to separate the ballpoint cartridge from the felt pen's reservoir.

The ink includes an elastomeric polymer such as Cis-1.4 Polyisoprene dissolved in an essentially non-volatile hydrocarbon solvent or plasticizer such as a light mineral oil and a colorant such as pigment particles evenly dispersed in the plasticized elastomeric polymer solution. The elastomeric polymer prevents the pigment colorant from penetrating into the writing paper surface. The preferred ink formulations also avoid or limit the use of volatile solvents which are detrimental to smooth writing characteristics for a ballpoint pen.

  • Patent number: 4228028
    Abstract: Disclosed is a ball point ink pen, its ink and its eradicator. The ink is carried at one end of the pen and the eradicator portion is carried at the other. If an error is made, the pen can be reversed and the eradicator used to neutralize the ink. The ink also neutralizes the eradicator so that when one rewrites with the same ink, any remaining eradicator on the paper is neutralized and the original ink acts as fresh ink.

  • Patent number: 4077725
    Abstract: A shoe polish applicator having a reusable handle-equipped body and a single-use polish-impregnated applicator pad. The pad is normally sealed in a protective wrapper which may be opened to expose the porous surface of the impregnated pad after that pad has been attached to a supporting head portion of the applicator body. Following use of the device, the pad may be ejected from the head portion into any suitable waste receptacle. The steps of attaching the pad to the head portion of the applicator body, the opening of the wrapper, the applying of polish, and the ejecting of the used pad from the applicator body may all be accomplished without touching the polish-releasing surface of the pad with the hands and without applying polish to any surfaces not intended to be so treated. The applicator as disclosed also includes, as part of the handle portion thereof, a hollow cartridge equipped with an applicator tip and containing a suitable liquid for dressing the edges of the soles and heels of shoes.
