Description

Ball Pen {Ball Pen}

The present invention relates to a ballpoint pen, and particularly relates to a ballpoint pen which can be easily handwritten with a simple structure.

Writing instruments originate from the fact that ink is kept on the feathers and flowed to the paper, so that the written contents are stored by leaving traces and forming letters according to the trajectory.

However, such a ballpoint pen has a complicated structure, and ink has been dried from the tip of the ballpoint pen or the ink reservoir into the atmosphere, thereby causing a problem in writing.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems occurring in the prior art, and it is an object of the present invention to provide a ballpoint pen which is simple in structure and inexpensive yet easy to use.

The ballpoint pen of the present invention for solving the above problems includes a ballpoint pen core in which ink is flowed out to the front end and handwriting is performed, a case in which the front end of the ballpoint pen core is exposed, and a lid sealingly covering the ballpoint pen core at the front end of the case .

According to the ballpoint pen according to the present invention, it is effective to provide a ballpoint pen which is simple in structure and low in cost and easy to use.

Further, the present invention prevents the ink from being dried and has the effect that the ball pen can be used for a long time.

Hereinafter, a ballpoint pen according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a ballpoint pen according to the present invention, FIG. 2 is an exploded perspective view of the ballpoint pen according to the present invention, FIG. 3 is an enlarged view of the ballpoint pen according to the present invention, and FIG.

The ballpoint pen according to the present invention includes a ballpoint pen core in which ink is filled and flows out to the front end, writing is performed, a case in which the front end of the ballpoint pen core is exposed, and a lid sealing and covering the ballpoint pen core in the front end of the case.

Referring to Figs. 1 and 2, a ballpoint pen according to the present invention will be described.

For example, the ballpoint pen core 400 is provided with a ballpoint pen tip at the front end of the tube containing the ink, and writing is performed by flowing the ink through the ballpoint pen tip. Oily or aqueous ink may be used depending on the composition of the ink. The tip of the ballpoint pen may also be a method in which a fine ball rolls at the front end of the tip of the ballpoint pen according to the composition of the ink or the ballpoint pen, and the ink flows out, or the ink becomes wet and the ink flows out on the same principle as the brush.

In other words, the design of the present invention is referred to as a ballpoint pen, so that the manner in which the ink flows out is not necessarily limited to the one provided with the ball, but the present invention is applied to any other method in which the equivalent ink flows out.

The case 100 has an inner diameter or a longer tube shape than the ballpoint pen 400 and is exposed at the front end as if the ballpoint pen tip of the ballpoint pen 400 protrudes. As a result, the user grips the case 100 and writes and writes the ink of the ballpoint pen 400 through the ballpoint pen to the paper.

The lid 200 covers the ballpoint pen tip exposed in front of the case 100 and is inserted into the front end of the case 100 to block air exposure. Thereby preventing the ink from drying to the front end of the ballpoint pen.

In addition, the case 100 may be opened only at the front end, but the back end is opened for convenience of manufacturing, so that the ballpoint pen 400 is inserted forward from the back end. In this case, a stopper 300 is provided to prevent the rear end of the opened case 100 from being opened.

It is preferable that the plug 300 is substantially the same size as the inner diameter of the case 100 so as to be forced into the case 100. If the lid 200 is separated from the case 100 for writing, By covering the stopper 300 at the back end, a side effect which is easy to store occurs.

On the other hand, the ballpoint pen according to the present invention contains ink inside the tube, and the ink flows out through the ballpoint pen tip, so that the ink advances forward due to the capillary phenomenon.

However, if the ink in the tube is advanced along the front side, the ink may be dried through the back end. Or when the viscosity of the ink is low, the ink remains in the inner diameter of the tube, resulting in a problem that the entire ink can not be used.

In order to solve this problem, as shown in FIG. 3, the follower 500 is provided at the rear end of the ink contained in the tube of the ballpoint pen 400.

The following body 500 includes a dipping portion 510 which advances along the ink while being held at the rear end of the ink, a follower portion 520 which advances together with the advance of the dipping portion 510 to scrape up the ink of the inside diameter of the bore, And a connection part 530 connecting the dipping part 510 and the following part 520. [

The immersed portion 510 may be, for example, a hydrophilic material or coated (in the case of a non-oil ink, a hydrophobic material or coated) in the case of an aqueous ink, and immersed in the back end of the ink, do. In addition, the dipping portion 510 has a suction port 512 formed at a predetermined depth in front of the ball-shaped central body 511 to allow the ink to enter the suction port 512, thereby increasing the capillary phenomenon. The center of the central body 511 The annular projection 513 is projected in the cross-sectional direction of the tube to increase the surface tension at the back surface of the ink. So that the dipping portion 510 easily advances along the ink with a higher force while being immersed in the ink.

The subsequent portion 520 serves to scrape up the ink remaining inside the tube while advancing along the dipping portion 510 to advance and collect the plate body 521 in the form of a plate corresponding to the inner diameter of the tube, 521 are provided with a ring body 522 protruding in a ring shape corresponding to the inner diameter of the tube in the same manner as in the forward direction so as to more easily and completely collect the ink while increasing the area of contact with the inner diameter of the tube. It is of course also possible to prevent drying of the ink at a higher level.

The dipping part 510 and the following part 520 are connected by a connection part 530 which is thinner than the dipping part.

Hereinafter, the operation of the present invention will be described with reference to FIG.

The dipped portion 510 of the follower 500 is immersed in the ink while the ink is filled in the tube of the ballpoint pen and the subsequent portion 520 covers the back surface of the ink to prevent drying.

The ink advances forward by the capillary phenomenon due to the flow of ink from the ballpoint pen core 400. When the dipping portion 410 immersed in the ink advances accordingly, the succeeding portion 420 connected thereto also advances together, Scrape together and move together.

Therefore, the ink in the tube is not dried and remains on the surface, so it can be used without waste.

The ballpoint pen described above belongs to the embodiment of the present invention and therefore it is not limited thereto and it is obvious that the scope of equivalence within the scope of the present invention is within the scope of the present invention even if there are some other variations.
