Description

Marker pen with ink refilling function

The present invention relates to a writing instrument for a blackboard, and more specifically, when the ink filled in the pen body is not used in the pen, evaporation is suppressed by being sealed to the outside, and if necessary, a predetermined pressure is applied to the operating cap of the pen. Technical writing is a writing instrument for a blackboard capable of replenishing ink in which ink filled inside the pen body is leaked to the front surface of the pen.

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 function of writing a predetermined amount of ink into the functional member after embedding the functional member in a cylindrical storage body, so that the handwritten ink is delivered to the front tip by a predetermined amount by capillary action.

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 for a blackboard formed with an ink outlet according to the prior art.

As shown, the fibrous fibrous nib 3 is fixed to the detention 2 coupled to the distal end of the pen body 1, and a filter 4 for absorbing ink is embedded in the detention 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.

When the knob is pressed, internal pressure is generated in the ink chamber, and since the internal pressure is not discharged to the upper portion sealed, the valve is released from the valve rod and the valve rod in the process of being discharged to the lower ink chamber. It is impossible to close the ball, and ink in the ink chamber is discharged through the lower part without permission.

In order to solve the above problems, the applicant's registration utility model No. 178305 has been registered. However, the applicant's technology can solve the above-mentioned problems, but the manufacturing cost increases because the ink receiving portion must be provided inside the pen body, and there is a problem in that writing instruments cannot be reused when the ink of the ink receiving portion is exhausted. .

Therefore, the present invention has been devised to solve the above problems, and when necessary, the ink outlet is automatically opened by applying a predetermined pressure to the operation cap, and the ink is leaked. It is an object of the present invention to provide a writing instrument for blackboard that is capable of refilling ink which is prevented from leaking and can be refilled inside the pen body.
