[Detailed description of the invention] The present invention relates to a notch-type writing instrument using water-based ink, and more specifically, to an improvement of a valve body in which the pen tip is placed in a hole at the tip of a barrel that can be freely retracted. .

Conventionally, ink-type writing instruments that use water-based ink have high fluidity and low viscosity, so when the pen tip is stored in the barrel and not in use, the tip of the barrel is completely sealed to prevent ink from evaporating. There was a need to prevent the pen tip from drying out. A valve body structure has been adopted as a means of completely sealing the tip of the shaft cylinder, but there are limits to accuracy, and although many inventions and ideas are known, they have not been commercialized. This is a major factor.

Therefore, in recent years, an approach has been taken to prevent the nib from drying out by developing water-based ink that dries extremely slowly, without relying on the valve structure, and this approach is steadily gaining recognition. Although the importance of the valve structure itself has diminished, the current situation is that it has not yet reached the point of eliminating the valve structure. The problem is that when the pen nib is stored in the barrel and not in use, it is often carried around in a pocket, etc., but there is fiber waste in the pocket etc., and this fiber waste and the pen nib are This is because if the ink comes into contact with the fibers, the ink will be absorbed by the fibers and cause staining of the clothing.

The above will be further explained using a specific example. Japanese Utility Model Publication No. 57-32183 states, ``As shown in the figure, the present invention is to provide a rubber shutter 1 with an airtightly closed opening 2, and to have a core tip 3 of an airtight cylinder 5 facing perpendicularly to the core b. A device related to a knob-type writing instrument is disclosed in which the scope of claims for registration of a utility model is as follows: ``Structure of a felt pen holder whose outer periphery is airtightly fixed in such a manner that the pen holder is airtightly secured to the outer periphery of the pen holder.''

According to this product, since airtightness is satisfied, it is thought that fiber waste present in pockets etc. will not attract ink and stain clothing. However, the rubber shutter 1
Airtight closure due to material deterioration over time and opening 2
Due to poor formation, it is difficult to obtain a product that is actually satisfactory. That is, the opening 2 may have a slight gap, or may have a slight gap. This gap is located at the part closest to the core b. In contrast, fiber waste is never short. In other words, prolonging the protrusion and retraction of the lead b is disadvantageous to the ejection and retraction mechanism, so when the lead b is housed in the airtight tube 5, the tip of the lead b should be placed as close to the inner wall of the rubber shutter 1 as possible. Designed to be located in In other words, the fiber waste will see the core b when it enters through the opening 2 of the rubber shutter 1. Therefore, the fiber waste easily comes into contact with the wick b, thereby staining the clothing.

Next, an example of a locking mechanism for making the pen tip 2 freely retractable will be explained based on the drawings.
The lower surface 6a of the tip of the presser 6 is fitted into the shaft cylinder 1 so as to be movable back and forth, contacts the rear end of the center shaft 3 which is biased toward the rear end by a spring 8, and is connected to the side tips of the presser 6. An engaging portion 6 is formed on the outer surface of the distal end of the locking piece 6b provided.
b' is provided in a protruding manner and protrudes from the hole 1b of the shaft cylinder 1. Reference numeral 7 denotes a clip, which has a V portion 7b on the front end that contacts or approaches the surface of the shaft cylinder 1;
The tip of the V portion 7b has a locking hole 7a facing the hole 1b, and when the presser 6 is knocked,
The bottom surface 6a of the tip of the presser 6 connects the center shaft 3 with the spring 8.
At the same time, the engaging part 6b' of the presser 6 also slides in the hole 1b of the shaft tube 1 toward the tip, and presses the tip of the clip 7 outward. The pen tip 2 protrudes from the tip of the barrel 1 and becomes ready for writing. If you want to store the pen tip 2 into the barrel 1, you can either pull the clip 7 outward with your finger, or insert your finger between the clip 7 and the barrel 1 and insert the locking hole 7a into the engaging part 6b'. When removed, the center shaft 3 and presser 6 are attached to the shaft cylinder 1.
The inner spring 8 pushes the pen tip 2 backward.
is housed in the barrel.

An example has been shown above, but according to this invention,
A plurality of elastic valve bodies with different free end directions are disposed in a hole at the tip of the barrel in which the pen tip can freely move in and out, and are arranged in a cross-shape with respect to the axis, and at least the rear one of the valve bodies is in contact with the axis. The length in the direction of the free end is longer than the radius of the hole at the tip of the cylinder, which simplifies the structure and allows each valve body to constantly abut with its elastic restoring force, preventing textile waste from coming into contact with the pen tip. prevent and also
Even if this contact force is insufficient, therefore,
Even if fiber waste were to enter the shaft cylinder,
The rear valve body prevents this fiber waste from going in the direction of the pen tip, that is, it makes the direction of the invading fiber waste different from the direction of the pen nib, so that the intruding fiber waste and the pen tip come into contact with each other. This has the effect of preventing stains on clothes as much as possible, and thus preventing stains on clothes.
