DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to a correction pen having the shape of a writing instrument, comprising a flexible barrel, a correction fluid prepared by dispersing a covering material such as white titanium pigment in an organic solvent and contained in the barrel, and a correction tip attached to the barrel, and capable of oozing out the correction fluid through the correction tip when the barrel is compressed between fingertips, and of being carried in a clothing pocket or the like.
BACKGROUND ART
Correction instruments which apply a white correction fluid to a paper sheet have been used to cover up incorrectly written marks. Recently, correction instruments respectively using color correction fluids of different colors have been marketed and used for marking as well as for writing. Demand for such correction instruments has greatly increased with the expansion of the application field. A correction instrument in an early stage of development was a simple bottle-type desktop correction instrument having a bottle containing a correction fluid therein, and a stick incorporated into the cap and provided at its free end with a brush. Such a simple bottle-type desktop correction instrument has been replaced with a squeeze correction instrument having a flexible container containing a correction fluid, a head cap for closing the container, and an application tip, capable of discharging the correction fluid through the application tip when the container is squeezed between fingertips, free from the possibility of spilling the correction fluid even if the container is laid sideways and capable of preventing the correction fluid from solidification even if the container is left uncapped. Recently various inventions and devices have been proposed to prevent the drying of the correction fluid on the application tip to avoid troublesome work for removing the solidified correction fluid from the inside of the cap and the application tip every time the squeeze correction instrument is used.
As shown in FIG. 6, a correction instrument according to a previously proposed device disclosed in JP-U No. 62-29103 has a barrel assembly E comprising a flexible barrel 1 having a fluid tank portion 111 and a reduced front portion 11 of a diameter smaller than that of the fluid tank portion 111, having an open front end, a correction fluid 3 contained in the barrel 1, a stirring member 4 contained in the barrel 1, a head member 2 having a coupling portion 22 fitted on the front portion 11 of the barrel 1, an application tip 66 serving as a front end portion of the head member 2 and as a component of a valve mechanism, a coil spring 8 resiliently biasing the application tip 66 forward and an annular member 10 having a spring bearing portion 10a. The annular member 10 is provided with a center hole 10c of a size allowing the application tip 66 to slide therein and allowing the correction fluid 3 to flow therethrough and a flange 10b held between the front end surface 1a of the front portion 11 of the barrel 1 and a shoulder 22c formed in the head member 2. A cap 5 is detachably put on a head portion 222 of the barrel assembly E.
With the expansion of the field of use of correction instruments as mentioned above, there have been proposed various correction instruments employing a ball capable of drawing lines of a fixed width and of writing letters as an application tip. One of those previously proposed correction instruments is disclosed in JP-U No. 5-80791.
As shown in FIGS. 7A and 7B, a barrel assembly E included in a correction instrument disclosed in JP-U No. 5-80791 is assembled by putting a correction fluid 3 and a stirring member 4 in a barrel 1 having a fluid tank portion 111, and a reduced front end portion 11 of a diameter smaller than that of the fluid tank portion 111, having an open front end, putting a ball 6 in a ball holding tube 7 having an inside diameter slightly greater than the diameter of the ball 6 and having a front end 7a bent inward by swaging to keep the ball 6 therein, fitting the ball
