Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a writing instrument in which a writing pen and a correction pen are combined.

[0002]

[Prior art]

 What was written with oily or water-based ink could not be corrected with an eraser, so it was necessary to correct it with a correction pen using a white correction liquid, but when it happened that there was no correction pen at hand, one by one There was an inconvenience such as having to search. In addition, when carrying it, it was necessary to prepare a writing pen and a correction pen. Therefore, it was considered to combine a writing pen and a correction pen, but it became very long, lacked in portability, and even if one pen could be used, the other pen could not be used. However, there was a problem that it could not be replaced.

[0003]

[Problems to be solved by the device]

 Therefore, as a result of diligent research, the present inventor has shortened the combined length of the writing pen and the correction pen and, at the same time, replaces the disabled pen with an ink or The inventors have found that the problem described above can be solved by screwing a part of the tank of the white correction fluid into the ends of the facing cylinders, and completed the present invention. That is, the present invention has both an oil-based or water-based writing pen and a correction pen, and is portable like a normal single pen, and can be replaced when one side becomes unusable. It provides writing instruments.

[0004]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the writing instrument of the present invention includes a writing pen 20 having a tank 21 of oily or aqueous ink and a correction pen 10 having a white correction fluid tank 11 therein, as shown in the figure. Is a removable writing tool, wherein the rear end of either the ink tank 21 or the white correction fluid tank 11 is formed into a male screw 12, and the writing pen 20 or the correction pen 10 is Either of the inner surface of the rear end portion of the cylindrical body 23 is formed into a female screw 24 and screwed.

[0005]

First Embodiment of the Invention A first embodiment of the present invention is shown in FIG. The writing instrument of the present invention comprises a correction pen 10 and an oil-based or water-based writing pen 20. The correction pen 10 includes a cylindrical body 13, a white correction fluid tank 11 formed in the cylindrical body 13 and having a rear end portion formed with a male screw 12, and a weight incorporated in the white correction fluid tank 11. 18, a pen tip 15, a holder 16 into which the pen tip 15 is fitted, and which is fitted onto the tip of the cylindrical body 13, and a cap 17 which is fitted into the holder 16 so as to be detachable. Since the structure of the correction pen 10 is known, a detailed description thereof will be omitted. The writing pen 20 is composed of a tubular body 23, a pen tip holder 30 fitted in the tubular body 23, and a cap 25 removably fitted in the tubular body 23. The cylindrical body 23 has an ink tank 21 formed therein, and a lens 24 is formed on the inner surface of the rear end portion of the cylindrical body 23. The nib holder 30 is provided with a nib 31, an ink core 32, and a nib 31 and an ink core 32 that are fitted therein and have fine passages 35, 36, and 37 for guiding air to the ink tank 21. It is composed of a fixed body 33 and a holder 34 into which the pen tip fixed body 33 is fitted and is fitted into the cylindrical body 23. Since the structure of a writing pen is known, a detailed description thereof will be omitted. The device of the present example is one in which the male screw 12 of the correction pen 10 and the female screw 24 of the writing pen 20 are screwed together to form an integral writing instrument.

[0006]

Second Embodiment of the Invention A second embodiment of the present invention is shown in FIG. The writing instrument of the present invention example comprises a correction pen 10B and an oil-based or water-based writing pen 20B. A male screw 22B is formed at the rear end of the ink tank 21B of the cylindrical body 23B of the writing pen 20B. A female screw 14B is formed on the inner surface of the rear end portion of the cylindrical body 13B of the correction pen 10B. The device of this example is one in which the external thread 22B of the writing pen 20B and the internal thread 14B of the correction pen 10B are screwed together to form an integrated writing tool.

[0007]

[Effect of the invention]

 This invention product is a combination of an oil-based or water-based writing pen and a correction pen that can be detachably attached to form an integrated writing tool, so that when a written document, pattern, etc. is corrected, a correction pen is searched for, etc. The inconvenience of is solved. Further, in the present invention, the length of the writing instrument screwed in can be shortened as much as possible by directly forming the screw on the ink tank of the writing pen or the white correction fluid tank of the correction pen. , It's short like a normal pen and convenient to carry. The product of the present invention is economical because it can be unscrewed and only the pen can be replaced if either the ink of the writing pen or the white correction liquid of the correction pen is used. is there. Further, since the product of the present invention is a connection by screwing, it is firmly connected and there is no problem such as disengagement during use.
