ABSTRACT:
TECHNICAL FIELD
This invention relates to the field of utensils and instruments useful for writing, including inkpens and the like. More particularly, it relates to writing instruments having a linear construction with a first and second end portion, wherein the first end portion is provided with a means for dispensing ink during a normal writing process, and the second end portion is provided with a correction tape dispensing provision.
BACKGROUND
Since the earliest of times when people began writing characters on substrates such as parchments, paper, and the like using various media as part of a written recordation system, persons making such written records or writings have inadvertently made errors in linguistical, numerical, and various other characters put down. In those cases where pencils and other means for applying written characters to a substrate are used that are easily erasable, a writer possessing a pencil that is equipped with an eraser on the non-writing end has the convenient luxury of making a quick erasure of a misplaced or incorrect character, and continuing on in the writing process, as is wellknown. However, it is generally true in the art that those particular media which lend themselves well to erasure, such as pencil graphite writings and certain so-called “erasable inks” do not have the permanency over time as do their more indelible counterparts, such as inks and other similar compositions. Thus, in many cases, and particularly those for which written records are desired to be maintained in legible form or extended periods of time, as in the case of legal documents, the use of non-erasable inks is highly desirable. Owing to human nature, however, it is inescapable that mistakes or other errors in entry of characters into ledgers et cet., will be made from time to time by persons using inks and the like, and means for correcting mistakes will always find a place among the writers supply list.
The prior art is replete with many means for assisting a writer with correcting errors made when using a relatively indelible substance such as an ink. One such means is a specially prepared paper which is erasable, such as Corrosible Bond® typing paper, that found widespread acceptance by typists beginning in the 1970's because the chemical nature of the surface of the paper enabled the typist to erase an erroneous typewritten character using an ordinary pencil eraser.
Another means for assisting a writer with correcting errors made when using a relatively indelible substance such as an ink is the use of what has become widely recognized in the art as “correction fluid”. Correction fluid is essentially a white paint substance which comprises a volatile solvent as the vehicle, which solvent is typically a halogenated hydrocarbon such as methylene chloride, etc., to enable the composition to be fast-drying to the user. In practice, the writer who has made an error typically unscrews the cap of a bottle containing the correction fluid, which cap is equipped with a brush means that is in contact with the liquid composition inside the bottle when the cap is in a closed position. The correction fluid which adheres to the brush upon its removal from the bottle is typically the needed quantity to correct most errors, and the user essentially “paints” over the mistake with the composition.
The prior art patent literature is replete with various contrivances associated with the use of correction fluid, the following examples being but a few: U.S. Pat. No. 4,511,273 teaches a correction fluid dispenser comprising a body member adapted to retain correction fluid, a barrel member received by the body member, a core portion extending axially of the body and barrel members, and a tip seal member disposed in a recess in the core portion and spring biased toward an orifice in the barrel member to block the orifice and prevent flow of fluid therethrough, the tip seal member being retractable against the spring bias to permit fluid flow through the orifice, the body and barrel members being operable to move the core portion, and thereby the tip seal member, into the orifice in blocking, nonretractable position. U.S. Pat. No. 4,572,691 sets forth a pen-like instrument for dispensing correction fluid comprising an elongate housing, a bag of thin flexible polymeric film material containing correction fluid within a cavity in the housing, and an applicator tip assembly comprising a body secured to the housing and the bag and having a through opening through which the correction fluid is dispensed when an applicator member positioned within the through opening separated from a lip on the body against the bias of a spring. U.S. Pat. No. 4,600,327 discloses a writing instrument having an ink applicator at one end and a hollow cylindrical reservoir at the opposed end containing a correction fluid. A first cap member is removably received on the instrument to cover the ink applicator when not in use and a second cap member is removably received on the opposed end of the instrument to enclose the reservoir. A fluid applicator brush is secured in the second cap and has a depending portion which is removably received within the reservoir in a stored position when the second cap is in place. U.S. Pat. No. 4,812,071 provides a correction fluid pen for applying a correction fluid, the correction fluid being of the type containing an opaque covering pigment and a volatile solvent. The pen includes a barrel with a manually squeezable plastic wall portion and an applicator with a spring biased stylus. The squeezable plastic wall portions advantageously have a bellows structure to facilitate the manual squeezing operation. The stylus is positioned within an orifice assembly which includes an orifice for passing the correction fluid. A portion of the stylus is moveable toward an exit opening for the orifice assembly for metering correction fluid passing out of the orifice assembly. U.S. Pat. No. 4,917,521 describes a pen type dispenser structure attachable to a container for ink correction liquid. The dispenser includes a frusto-conical liner wall formed into a spiral configuration; a shaft extends from the small end of the liner wall into a liquid discharge opening formed in the tip end of a surrounding cover. A manually-squeezable lever is mounted on the container for rotating the cover. A wedge surface on the cover interior surface is slidably engaged with a wedge surface on the spiral liner wall, such that rotation of the cover causes the spiral liner to move the internal shaft away from the liquid discharge opening at the tip end of the cover. U.S. Pat. No. 4,923,317 teaches a brushless white-out correcting fluid applicator for use in applying white-out fluid to paper without using a brush. The white-out fluid is a suspension including a substantial proportion of white or substantially white particles, such as titanium dioxide, or other color particles. The applicator includes a wear-resistant, porous tip and a regulator between the tip and a reservoir. The regulator may be formed of foam material, and the tip may be of sturdy porous plastic. The size of the pores in the tip and regulator are large enough so that they do not become clogged with particles in the white-out fluid. The regulator prevents the tip from dripping by regulating the rate at which fluid can leave the reservoir. The size of the pores adjacent the reservoir may be different than the size of the pores and passageways adjacent the tip. The applicator may be provided with an air-tight cap to avoid drying out between uses. Alternative embodiments of the applicator include a foam tip with a nylon mesh outer covering for wear resistance; and an internal, pressure actuated valve may be included to regulate the flow of the white-out suspension to the tip. U.S. Pat. No. 5,056,949 sets forth a correction fluid dispenser comprising a body member adapted to retain a correction fluid and a barrel disposed at one end thereof for delivery of the fluid to a surface. The barrel terminates in an orifice formed by a circular rim with a
