Description

[Detailed description of the invention] Background of the invention The present invention is designed for the goal-in base.

The conventional pole is conical in shape and has a brass missing end with a 7-tenure steel barrel at one end.

This tip communicates with the ink supply channel, from which ink reaches the gale, which collects ink while it runs over the paper and distributes it onto the silver distribution section. Behind the tip is a small chain containing an ink supply made of brass or a suitable glass material.

Both of these parts form what is referred to in technical terms as a "refill".

This refill is inserted into a hollow case made of wood, metal or glass material. The actual construction of these ins begins by forming a tip obtained from a brass par of cylindrical or conical shape, which tip is then drilled to obtain an ink supply channel within it; #*K is caught.

After being prepared in this manner, the tip is connected to a small tube filled with ink. The latter is usually an oily dye solution made up to the appropriate degree by the addition of a resin, and must not contain any suspended particles and must be extremely stable as a dye, such as citron oil ( Castor oil II
l! -), fatty acids (such as oleic acid and ricinoleic acid) and glycerin are used as oily carriers, while natural or synthetic resins are used as thickening agents.

The ink must not drip from the metal tip and must have adequate surface tension so that it can evaporate in a few seconds.

There are also other 8111ji ins that are commonly referred to as fiber pens, and this term refers to both fiber pens and felt tip pens.

The felt-tip pen consists of a pen holder made of plastic material, and the tip thereof is equipped with a thick core (felt) for the brush F. This felt continues into the pen holder 1111, which is soaked with brush IF ink from the wet cartridge. The basket wiring can be made thick or thin depending on the thickness of the felt.

The top of the inholder is closed by a stopper, and the tip is also closed and kept stationary by a cap-like cover or cover when not in use.

A two-eye pen, also known as a nylon tip, is basically made up of two internal parts.

That is, the tip for practice F, ie, the pen tip, and the reservoir, ie, the pad. The tip for stage Ill consists of a bundle of nylon or acrylic fibers and is obtained by polymerization. This polymerization 111 creates a gap between each single mackerel fiber and the adjacent one, through which the ink uniformly flows down by capillary action.

(The polymerization process used to form the tip yields a tip with a diameter four to five times larger than the required one. Therefore, by a stretching or stripping action, the diameter of the tip can be reduced. A post-diaphragm is provided to reach the size of use, eK. It is done only to allow said intermediate gap to be interdependent on P! and diverge.

Fine point and drafting pens are made from the resulting tips. Fine point pens have a hard, conical tip, while drafting pens typically have a soft tip made of treated and polymerized polyester fiber bundles.

The reservoir is a small hollow cylinder made of tetracyclized vinyl, usually obtained by extrusion, containing bundles of cellulose acetate fibers of varying density depending on the presence or absence of diluent in the ink. It is filled with a bunch of riester wire miscellaneous.

Finally, the ink is water-based and contains additives to improve writing quality.

The latest pens on the market have an ink reservoir or /4, de,
? It is composed of capillary elements (small sticks) made of ester fibers that are distributed between the two layers.

The usage of these pens is the same as that of the aforementioned pens other than the traditional 11-le-pen, and is based on the principle of capillary action.

In fact, the small school, Riha no 9. It has a much smaller diameter than the de, and is caused by capillary action? The ink is carried in a trench right next to the wheel, which rotates and distributes the ink onto the paper.

However, although these pens combine the features of each of the aforementioned ins, they still have significant deficiencies. Since the binder used to hold the particles together reduces the inter-porosity required for capillary action, K expends a larger If to dispense the ink one by one. However, if you do this, the small stick will no longer be directly in the pool.
1i#! Therefore, in the case of a very large angle, the water-based ink no longer wets the part and appears impossible to write.

Previous 1. Remove defects to allow direct contact between the part and the small stick with weak capillary action.
It has been attempted to insert an element or an offering thereof having a j+1 section T# shape, but we are not in a position to solve this problem, and furthermore, the case in which these pens #i partially encloses is made of steel. If it is a zoranutic material, as is actually used, it is obvious that due to the tolerances of table making, the outer edge of the case, rather than the outer edge of the case, can be written normally. However, this contains dirt and therefore cannot be written very cleanly.

OBJECTIVES The problem underlying the present invention is to overcome the above-mentioned deficiencies and at the same time to provide a ferrule that is partially in-line, which allows for a clean, unsmudged dispensing even at one angle of inclination of the tip. This problem is solved by the present invention comprising a sleeve of plastic material with a longitudinal through hole therein, the through hole having a circular cross section of diameter I over a predetermined length. and having a circular cross-sectional portion of a larger diameter over the remaining length, and a complimentary internal stepped ring is formed at the boundary between the two portions, the ring having a longitudinal through-hole of a smaller diameter, The end of the small chain of stainless steel press-fitted into the circular cross-sectional hole of the diameter, and the end of the small chain opposite to the end that engages with the ring is located forward from the nup. A stainless steel tip formed at the end of said tip 1-de by longitudinal punching on three or more and arranged in a suitable housing comprises a portion of a small tube of small diameter. Inside and inside the hole of the sleeve, a bundle of crimped 4-ester Ill## is formed and a twine is arranged, one end of which is attached to the three or more long planes mentioned above. The prong is fixed to the end of the small tube with the JL opening, and the a end protruding from the sleeve is attached to the rear of the cap.
Immersed in an ink pad formed by a bundle of cellulose acetate fibers or polyester fibers, the first one is further immersed in the small steel crystals.
The cap is provided with an external annular stepped ring near the end where the cap is mounted, and the cap is designed to contact the front of the barrel case when the cap is installed within the barrel's external case. This problem is solved by the part-in cap.

Detailed 1B of a preferred embodiment of a goal pen cap is given with reference to the accompanying drawings whose features and benefits are shown by way of example. It will become clear in the light.

In the drawing VC of the preferred embodiment, a part of the inn provided with the cap which is the object of the present invention is shown at 1.

The Akira cap has a sleeve 2, a small stainless steel chain 3, and a small loop and crimp (IID) also made of Nuterre.
The sleeve 2 is comprised of a cord formed from a bundle 25 of bulky and stretchable polyester fibers.The sleeve 2 is provided with a longitudinal through hole, which has a circular section 6 of small diameter over a predetermined length. , which has a circular section 7 with a large diameter over the remaining length. A round internal stepped ring 8 is formed at the boundary II of these two parts and connects it to one end 31 of the small tip 3. together,
The small die 3 is provided with a small diameter through hole 9. The skeleton tube 3 is press-fitted into the bore 7 of the sleeve 2, and its end 3b opposite said end 3a is supported in an internal stepped ring 8 and projects forwardly from the sleeve 2. The end 3b of the small hole 3 is rotated into a socket formed by three or more longitudinal nozzles 11 provided behind the small hole 4 in the small tube 3. Some of the small pieces that can be accommodated freely include 4.

A string formed of 50 bundles of ester fibers extends through f19 of the small chain 3 and through the hole 6 of the sleeve 2, and its end 5b is firmly attached to the part of the small pipe 3 provided with the above-mentioned knotting 11. installed.

In this way, there is a direct connection between the tip of the string made from 50 bundles of polyester and /J\Gale! One touch will void the warranty.

The other end of the string protrudes from the sleeve 2 and
For example, cellulomere acetate fibers filled in a cylindrical case 14 provided in a cylindrical case 14 are immersed in an ink tube 12 made of a bundle of polyester fibers.

In order to easily and correctly assemble the cap into the inner case 14, and to avoid damage to the ester** at the end of the 15m string, the outer circumferential surface of the sleeve 2 is clearly outside the drawing. The Theno Parable is attached upwards.

Due to the principle of capillary action underlying the use of these inks, a significant advantage obtained by employing the inventive nozzle is that the ink reaches the small I-le through three stepped sections (). This is due to the fact that the overall capillary action is greatly increased by kneading (the part of the string inside the hole 6 and the part of the string close to the punching 11 in the small chain 3). As a result, in this particular case the amount of ink that reaches the part is much greater than with known conventional methods.

Furthermore, it should be understood that a strand of string fixed to a portion of a loose steel tip with a notch is always in direct contact with the tip.

Thus, no matter what the inclination angle of the ink, the ink always reaches the small hole, so that the use of this pen always results in a clean, smudge-free and, more importantly, uniform Guarantees an unbroken line.

While the above-described cap embodiments are clearly preferred, they do not fall within the spirit and scope of the invention as defined in the claims.
It should be understood that the structure of the cap can be modified without causing damage.
