Description

Board marker {BOARD MARKER}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a board marker, and more particularly, to a board marker capable of easily replacing a filling portion filled with liquid ink from a board marker.

Liquid board markers are instruments used for writing on boards that have a smooth surface such as a white board and have a surface treated and not hygroscopic.

The chalkboard is painted with black paint such as wood with wooden plank, and chalk is used for writing. Chalk is also called chalk. It is made of gypsum and hardened. It can be easily wiped with cloth after writing on the board. It is widely used in schools and auditoriums.

Chalk is inexpensive and has been used for a long time because it can be wiped off immediately after use on a blackboard. It has been used for many years because it is disadvantageous because it is harmful to health, .

Due to the above-mentioned problems of the chalk, a liquid-phase board marker, which is hardly dusted and can be used for a long time and is not broken, is often used recently.

The liquid board marker is a writing instrument that fills ink inside a barrel and installs a lip having excellent hygroscopicity on the entire barrel so that the ink leaks out through the lip and is exposed to the plate while being in contact with the board.

A material having excellent hygroscopicity such as a sponge is inserted into the barrel so as to prevent the ink from flowing out, so that the ink is absorbed. When the board marker is used on the board, the lip portion is used up to 70 °. If the hygroscopic material is not used, the flow of ink between the ink and the lip is not formed and the supply of the ink is stopped. Can not be performed. Since the lip has a limit in absorbing the ink, a hygroscopic material that functions as a flow path for connecting the lip to the ink is necessary.

Since the board marker uses liquid ink, it can hardly generate dust when used and can be written continuously until all the ink is used. Therefore, it can be written for a long time and does not break, .

Although board markers are widely used in recent years due to the advantages described above, since a large amount of the ink used for the hygroscopic material can not be used even if both of the ink are used by using a hygroscopic material such as a sponge so that the ink filled in the barrel is not leaked during use The consumption of the ink is increased, and the ink that is put on the board through the ribs is primarily filtered through the hygroscopic material, so that a color change occurs.

FIG. 1 is a sectional view showing a board marker according to the present invention, and FIG. 2 is an enlarged sectional view showing a board marker according to the present invention.

1 and 2, the board marker 100 of the present invention comprises a case 110, a filling unit 120, a lip bar 130, and a connection unit 140.

The case 110 has a cylindrical shape.

In the case 110, a main space 111 and a sub space 112 are formed to communicate with each other through a flow hole 113.

That is, a sub-space 112 is formed at one side of the case 110 to which the lip 130 is coupled, and a main space 111 is formed at the other side of the case 110 to allow the filling unit 120 to be inserted therein.

The sub space 112 and the main space 111 are connected to each other through a flow hole 113.

The lip bar 130 is coupled to the sub-space 112 such that a portion of the lip bar 130 is exposed in the sub-

In addition, the filling part 120 is installed in the main space so as to be able to be replaced by filling the liquid ink 121.

In addition, the connecting portion 140 is provided with a ball 141 on the upper portion of the lip 130 of the sub-space 112, and a penetrating means integrally formed on the upper portion of the ball 141 penetrates the flow hole 113 and the main space 111 and penetrates into the filling portion 120 The ink 121 is caused to flow to the lip bar 130.
