Description

Marker pen with effluence hole}

The present invention relates to a writing instrument, and more particularly, the ink outlet is automatically opened by a predetermined pressure applied from the outside, and a predetermined amount of ink flows out through the ink outlet, so that the water-containing member wets the front tip. It relates to a writing instrument formed with an ink outlet that is automatically closed when the ink outlet is released to prevent the flow of ink.

A writing instrument generally used includes a ball-type writing instrument in which a ball is inserted in front of the writing instrument and ink is leaked by the flow of the ball, and ink is filled in a predetermined amount in front of the storage body by filling ink into a cylindrical storage body. It is divided into functional writing instruments that are written by feeding the front tip.

In general, a magic pen, a sign pen, a highlighter, a board marker, and the like have the above-described functional writing instrument.

The functional writing instrument has a built-in functional member inside the cylindrical storage body and then writes a predetermined amount of ink to the functional member so that the functioned ink is delivered to the front tip by a predetermined amount by a capillary phenomenon.

However, the writing instrument has a problem in that ink is easily evaporated through the front tip and the ink cannot be used for a long time because the amount of ink that is water-containing in the water-containing member is limited.

In order to solve the above problems, conventionally, writing instruments have been developed in which an ink chamber is formed inside a storage body and the ink filled in the ink chamber is discharged downward by a predetermined amount.

The prior art will be described in detail with reference to the accompanying drawings.

1 is an exploded cross-sectional view of a writing instrument having an ink outlet according to the prior art.

As shown, the fibrous fibrous nib 3 is fixed to the cap 2 coupled to the distal end of the pen body 1, and the filter 4 absorbing ink is embedded in the cap 2. A flexible elastic diaphragm 5 is formed on the upper end side of the pen body 1 so as to be integrally shielded with the pen body 1. Then, the inner space of the pen body 1 becomes the ink chamber 1 'for storing ink, and the valve hole (1) is provided on the inner end side of the detention 2, which is an intermediate portion of the ink chamber 1' and the filter 4. Insert the valve cap 7 formed with 6) to block the ink chamber 1 '. In addition, the outlet 6 'of the valve hole 6 is connected to the filter 4, and the valve hole 6 connected with the valve rod 8 is installed in the valve hole 6 with the operation spring 10 to install the valve rod ( The end of 8) is in contact with the diaphragm 5 of the ink chamber 1 ', and on the outside of the diaphragm 5, the knob 11 for pressing the valve rod 8 is brought into contact with the fixing stopper 12. It is composed.

The operation effect by the above configuration is as described later.

When no downward tension is applied to the knob 11, the valve hole 6 is blocked by the valve 9 compressed by the elastic force of the actuation spring 10, and the ink in the ink chamber 1 'is discharged. 6) and the ink which does not flow out to the outflow hole 6 'and is absorbed in advance by the filter 4 is transferred to the pen nib 3 so that writing is possible for a while.

When the ink absorbed by the filter 4 is consumed during writing and the text becomes faint, downward tension is applied to the knob 11, and the knob 11 is driven by the diaphragm 5 by the downward tension. Press the valve 9 to open the valve hole (6). Therefore, the ink in the ink chamber 1 'is supplied and absorbed into the filter 4 through the open valve hole 6 and the outlet 6'.

When the downward tension applied to the knob 11 is released, the valve 9 is returned by the elastic force of the actuation spring 10 of the valve rod 8 so that the valve hole 6 is blocked and the ink chamber 1 'is sealed. It is retained and can continue writing with the ink absorbed and supplied to the filter 4.

However, the writing instrument includes the problems described below.

First, when the knob is repeatedly pressed, the elastic restoring force of the actuation spring decreases so that even when the knob is not pressed, the valve hole is opened and ink flows out to the filter through the outlet.

Second, since the internal pressure is generated inside the ink chamber when the knob is pressed, and the internal pressure is not discharged to the upper portion sealed, the coupling of the valve rod and the valve rod is released during the discharge to the lower portion of the ink chamber. The valve rod does not close the valve hole so that the ink inside the ink chamber is discharged through the lower portion.

Third, since the knob is formed at the upper end of the pen body, the writing operation is paused for a while to press the knob, and the hand has to be moved by pressing the knob.

Fourth, it is not economical because a large number of accessories are required to spill the ink of the storage compartment to the bottom.

Therefore, the present invention is devised to solve the above problems, the ink filled in the ink receiving portion is automatically discharged through the ink outlet formed in the lower portion of the ink receiving portion by the external tension applied to the ink receiving portion fixed tip It is an object of the present invention to provide a writing instrument in which an ink outlet is formed so that the ink outlet is automatically closed when the tension is released and the ink outlet is automatically closed.

Another object of the present invention is to provide a writing instrument having an ink outlet, through which the external tension applied to the ink receiving portion can be transmitted through the outer circumferential surface of the ink receiving portion so that ink inside the ink receiving portion can be discharged to the lower side during writing. .

It is another object of the present invention to provide a writing instrument in which an ink outlet is formed in which the number of parts required to wet the fixing tip is minimized when the ink of the fixing tip is dried.
