Description

[Technical field]

[0001] The present invention relates to a refillable alcohol marker pen, and is mainly concerned with the design of a refillable alcohol marker pen that allows ink to be quickly refilled through an inlet, and the process is simple and convenient. [Background technology]

[0002] Conventional marker pen ink contains alcohol. Therefore, the ink in the conventional marker pens is likely to run out quickly due to the problem of volatilization, but generally, the marker pens cannot be used repeatedly, and a new marker pen must be purchased and used again after disposal. This is obviously wasteful and does not meet the modern needs in which environmental protection is emphasized. In addition, the nib of the conventional marker pen is made of a hard material to prevent the amount of ink from volatilizing quickly from the nib. Therefore, the conventional marker pens cannot smoothly control the variation of the thickness of the touch when used for writing or drawing. In addition, when the nib and the pen shaft are disassembled by applying force, the ink remains in the pen shaft, so that the ink often spurts out over the entire hand and even the whole body, making it extremely difficult and complicated to refill the ink. Therefore, most general users choose to purchase a new marker pen after disposal. In the above points, there is room for further improvement. Summary of the Invention [Problem to be solved by the invention]

[0003] That is, the primary object of the present invention is to provide an alcohol marker pen that can be refilled with ink. In addition, the problem that the present invention aims to solve is to overcome the problem that conventional marker pens have pen tips made of hard materials to prevent the ink from evaporating too quickly from the pen tip, making it difficult to smoothly control variations in the thickness of the stroke when used for writing or drawing, and there is room for further improvement. [Means for solving the problem]

[0004] As described above, the main body of the present invention is provided with a refill introduction hole that allows the ink inside to be refilled from the outside. The refill introduction hole can be matched with and combined with the elongated guide rod provided in the refill device. The elongated guide rod has an introduction port that allows the refill liquid to be refilled and sent out, so that the present invention can quickly refill ink through the introduction port. This process is simple and convenient, and there is no problem of ink leakage and staining due to inaccurate alignment. Furthermore, there is no need to worry about the problem of reduced usage rate due to volatilization after refilling the ink. This provides practicality and inventiveness in terms of convenience in use of the present invention. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0006] Please refer to Figures 1-10, which show the preferred embodiments of the refillable alcohol marker pen of the present invention. It should be noted that these embodiments are provided for illustration purposes only, and the application of the invention is not limited to these structures. The refillable alcohol marker pen includes:

[0007] Body 10: The cross section of the body 10 is an elliptical rod cross section so that it can be easily held in the hand to write or draw. At the tip of the body 10, a pen tip 13 and a pen cap 18 that seals the pen tip 13 are provided. A filling chamber 101 is formed inside the body 10. The filling chamber 101 is filled with ink A. The ink A contains an alcohol component. The ink A is delivered to the pen tip 13 as a liquid. The pen tip 13 has a circular base 133 formed at the bottom. The circular base 133 is integrated with a rectangular inclined end surface 131 on the top surface via a part that has a rectangular cross section extending from the bottom to the top. A connection part 132 is formed between the rectangular inclined end surface 131 and the circular base 133. Depending on the shape of the pen tip 13, it is possible to more easily write or draw various variations in the shape of lines. In addition, the pen tip 13 is made of a soft and flexible synthetic material. Therefore, the user can write characters or draw pictures more easily and smoothly by controlling the variation in thickness of the touch with various strengths of force. The main body 10 may be made of a transparent material so that the volume of the ink A can be clearly recognized.

[0008] A pen tip 12 is provided at the bottom of the pen tip 13. The pen tip 12 extends toward the bottom end of the body 10, and an engagement portion 11 is provided on the extended periphery. The pen cap 18 is provided with an engagement end 19 corresponding to the engagement portion 11. The engagement end 19 of the pen cap 18 is positioned to correspond to and engage with the engagement portion 11 of the pen tip 12 so that the pen cap 18 does not easily fall off the pen tip 12.

[0009] A bottom base portion 14 and a movable cover 20 are provided at the bottom end of the main body 10. A cover groove 16 is provided on the ceiling surface of the bottom base portion 14. The cover groove 16 allows the movable cover 20 to be closed. A fitting groove 15 is provided on one side edge of the cover groove 16. The movable cover 20 is provided with a fitting end 21 corresponding to the fitting groove 15. The fitting end 21 can be fitted and positioned in the fitting groove 15. A refill introduction hole 17 is provided in the center of the cover groove 16. The refill introduction hole 17 communicates with the filling chamber 101. Furthermore, a pivot connection portion 23 is provided at a position on the movable cover 20 opposite to the fitting end 21. By connecting the pivot connection portion 23 to the bottom base portion 14, the movable cover 20 is pivotally connected to the bottom base portion 14 of the main body 10 in an operable manner to open or close the bottom base portion 14. In addition, the movable cover 20 is provided with a sealing protruding rod 22 corresponding to the refill introduction hole 17. The sealing protruding rod 22 is assembled to the refill introduction hole 17 in a sealed manner.

[0010] Refill device 30: has a space 31 inside, and refill liquid B is filled in the space 31. An elongated guide rod 34 is provided at one end of the refill device 30. The outer diameter of the elongated guide rod 34 is smaller than the refill introduction hole 17 of the main body 10. This allows the elongated guide rod 34 of the refill device 30 to be guided and inserted into the refill introduction hole 17 of the main body 10. Furthermore, an introduction port 35 is provided at the tip of the elongated guide rod 34. The introduction port 35 is connected to the space 31 filled with refill liquid B. The refill liquid B is sent from the introduction port 35 to the inside of the refill introduction hole 17. This guides the refill liquid B to the filling chamber 101 inside the main body 10 and causes it to flow in, thereby performing the refill operation of the ink A.

[0011] The replenishing device 30 is further provided with a fixing section 32 at a position corresponding to the elongated guide rod 34. The fixing section 32 is provided with a male thread 33 on its outer periphery. The fixing section 32 is provided for closing and positioning a cap body 36. The cap body 36 is provided with a fixing groove 37 inside. The fixing groove 37 is provided with a female thread 38 that can be compliantly screwed into the male thread 33 inside. Thus, the female thread 38 is operably screwed into, assembled with and fixed to the male thread 33 of the replenishing device 30.

[0012] Preferably, the alcohol marker pen refillable with Ink A in the present invention can be used as a whiteboard pen.

[0013] As described above, the main body 10 of the present invention is provided with a refill introduction hole 17 that allows the ink A inside to be refilled from the outside. The refill introduction hole 17 corresponds to and can be combined with the elongated guide rod 34 provided in the refill device 30. The elongated guide rod 34 has an introduction port 35 that allows the refill liquid B to be refilled and sent out, so that the ink A can be quickly refilled from the introduction port 35 in the present invention. In addition, there is no need to worry about the problem of reduced usage rate due to ink volatilization, and the service life is extended. [Explanation of symbols]
