るために外したキャップが紛失する欠点があった。(Prior Art) There is a knock-type writing instrument of this kind that has been devised to prevent evaporation of ink from the pen tip to some extent without covering the cap, but if it is stored for a long period of time, For example, if the period from the time of shipment to the time of being placed in a store and reaching consumers is long, the evaporation of ink is inevitable. Therefore, the refill may be placed at the store in a state of being airtightly packed separately from the barrel. Therefore, the consumer has to take the refill out of the package and mount the refill in the barrel, and there is also a problem that the cost is increased due to the packaging of the refill. On the other hand, there is a knock-type writing instrument having a structure in which a cap is attached to the tip of the shaft cylinder, but there is a drawback that the cap removed for writing is lost.

The embodiment shows a water-based ballpoint pen, in which a refill 2 is housed inside a barrel 1 in a state of being biased rearward by a coil spring 3, and a locking projection 4 is integrally formed on a side surface of the refill 2. , A long hole 5 in the axial direction is formed in the side surface of the shaft cylinder 1, the locking projection 4 of the refill 2 is fitted into the long hole 5 of the shaft cylinder 1, and the side surface of the shaft cylinder 1 has a long hole. An elastically deformable clip 6 is provided at a position facing the hole 5, a tip stepped ball portion 7 of the clip 6 is provided with a locking step portion 8, and a rear end portion of the shaft cylinder 1 is provided with a rear portion of the refill 2. A knock base 10 for abutting the end and fitting a projection 9 provided on the side surface into the elongated hole 5 of the shaft cylinder 1 is slidably mounted in the axial direction, and the front half of the opening end has a small diameter and is located on the top surface side. The rear half has a large diameter, and the front half small diameter portion 11 is dimensioned to have an outer diameter that can pass through the front end opening 12 of the barrel 1 and the riff. The tip 15 of the reel 2 is provided with a cap 15 sized to be able to be attached to the tip small diameter portion 14 of the refill 2 in a state where the tip nib 13 is immersed in the shaft, while the rear of the knock base 10 described above is provided. The end face is provided with a fitting hole 16 for the first-half small-diameter portion 11 of the cap 15.

がない。(Operation) The operation will be described based on the above embodiment. First, FIG. 1 shows a storage state, in which the pen tip portion 13 of the refill 2 is recessed inside the shaft, and a cap 15 is attached so as to cover the pen tip portion 13 of the recessed refill 2. .
Therefore, even if the storage period is long, the evaporation of the ink from the tip portion 13 is suppressed, and the writing life of the refill 2 is prevented from being shortened. When used next, remove the cap 15 from the refill 2 and fit the cap 15 into the fitting hole 16 of the knock base 10 attached to the rear end of the barrel 1 as shown in FIG. The top surface 17 of the cap 15 may be knocked. The refill 2 moves forward while being compressed by the knock base 10 while compressing the coil spring 3, and the locking projection 4 that has been guided and advanced in the long hole 5 hits the sandwiching ball portion 7 of the clip 6 to elastically move the clip 6 upward. After passing through the lower surface by being deformed, it is engaged and fixed with the locking stepped portion 8. At this time, the pen tip portion 13 of the refill 2 projects from the tip end opening 12 of the barrel 1 as shown in FIG. Writing is possible. Therefore, when writing, the cap 15 is the knock base 1
There is no risk of loss because it fits in 0 and becomes part of the knock part.

る。(Effects of the Invention) As described above, the knock-type writing instrument of the present invention prevents the ink from evaporating from the pen tip even when it is stored for a long period of time and prevents the refill writing life from being shortened. The cap has a function that allows the front half small-diameter portion to be fitted into the fitting hole provided in the knock base body to become a part of the knock portion, and the knock allows the tip nib of the refill to appear in and out of the shaft tip opening. Therefore, it is possible to prevent the cap from being lost when it is written, and the cap is not left unused without being used.
