Description

Writing implement and method of separating pen core holder}

The present invention relates to writing instruments such as marking pens and ballpoint pens that can remove a pen core holder.

Japanese Utility Model Publication Nos. 51-14262, 202-52-2504, 52-46175, etc. are known as writing instruments which allow the pen nib such as felt nib, plastic nib, ball tip nib to be detached from the writing instrument body. have. Such writing implements can replace the nibs and refill the ink after removing the nibs. However, scratching occurred because the nib was held directly, and it was almost impossible to reuse the nib.

Therefore, a writing instrument in which the pen core holder holding the pen nib is detachable from the writing instrument body is invented, and Japanese Utility Model Publication No. 62-5353 and the like are known. Such writing instruments can be replaced without scratching the pen nib, and the ink can be replenished after removing the pen nib holder. However, it is inconvenient because the structure is complicated, such as screw-fitting the pen lead holder and the writing instrument body.

Therefore, the present invention overcomes the above problems, and provides a writing instrument capable of detaching the pen core holder from the main body by an easy means, and a method of detaching the same.

In the writing instrument which consists of a main body and a cap which supported the pen core holder, this invention forms the engagement part in the said pen core holder, The writing instrument which provided the projection part in the said cap, and the said projection part engages the said projection part, A pen core holder detachment method for detaching a holder from a main body.

(Example)

The writing implements of the present invention will be described in detail with reference to the embodiments shown in Figs.

Reference numeral 1 denotes a pen core holder, which forms an engaging portion 2 on the outside, and similarly, a locking portion 3 for preventing the pen core holder from entering the main body is formed on the outside. Moreover, the pen core 4 which consists of acrylic fiber is supported inside the pen core holder. In the present embodiment, the engaging portion 2 and the engaging portion 3 are projected to the entire outer circumference of the pen core holder 1, so that both are formed in a groove shape.

Reference numeral 5 denotes a main body, which supports the pen core holder at its tip and incorporates an ink absorber made of polyester fiber.

Reference numeral 6 denotes a cap, which has a shape in which a part of the cap is scraped off, and the protrusions 7 are formed at the tip portion. In the present embodiment, the thickness of the projection 7 is set to the same thickness as the width of the groove shape formed by the engaging portion 2 and the locking portion 3.

In order to replenish ink or replace all of the pen core holders, first, the projections 7 are engaged with the engaging portions 2, and specifically, the projections 7 are fitted with the engaging portions 2 and the engaging portions ( 3) The cap 6 and the main body 5 are pulled in the opposite direction by being fitted in the groove shape formed by. Doing so removes the pen core holder 1 from the main body 5, and thus replenishes ink in the openings of the main body 5, if necessary. In particular, in the present embodiment, since the projection part 7 is inserted into the groove shape formed by the engaging part 2 and the locking part 3, the pen core holder 1 is mounted on the main body 5. It remains engaged even after it is removed, so that the fingers are not soiled regardless of where the pen nib holder is placed while refilling the ink. Then, when the pen core holder 1 is inserted into the main body 5 with the cap 6, it returns to the state which can be written again.

In this embodiment, a tail plug 9 is supported on the main body 5 with the packing 10 interposed therebetween. Moreover, the recessed part 8 is formed in the end of the tail plug 9. In order to remove the tail plug, the projection 7 of the cap 6 is inserted into the recess 8 and the two are twisted. By doing so, since a part of the projection 7 acts as a point and the other part pushes up the tail plug, the tail plug 9 can be easily detached from the main body 5. Alternatively, the tail plug 9 can be detached from the main body 5 even when the protruding portion 7 of the cap is inserted into the concave portion 8 and pulled out.

Next, the ink absorber incorporated in the main body 5 can be removed, and the fractionation process is easy. If necessary, ink may be replenished in the rear opening of the main body 5. In this invention, since the said projection part 7 is formed in the cap, it is not necessary to prepare a driver etc. deliberately, and it can separate easily by a user.

Although the cap and the pen holder of another Example are shown in FIGS. 4-10, it cannot be overemphasized that this invention is not limited to the said Example.

In the cap of Example 2 shown in FIG. 4, FIG. 5, the projection part is formed in the tip part of the shape which cut off a part of cap, so that both may become groove shape.

The cap of Example 3 shown to FIG. 6, FIG. 7 forms the blade-shaped protrusion part in the front-end | tip part of a cap.

In the pen core holder of the fourth embodiment shown in Fig. 8, the engaging portion is provided on the outer side of the tip end of the pen core holder, and is formed integrally with the engaging portion which has a smaller projecting distance than the engaging portion. To have. To disengage the pen core holder from the main body, hook the projection to the engaging portion and pull the cap and the main body in opposite directions. This will allow both to break away.

In the pen core holder of the fifth embodiment shown in Figs. 9 and 10, the engaging portion and the engaging portion are integrated, and then the notch 11 is formed in a part of the engaging portion. To detach the pen core holder from the main body, the projection is inserted into the cutout portion 11, hooked to the engaging portion, and the cap and the main body are pulled in opposite directions. Doing so can dislodge both.

In the present invention, any combination of the caps and the pen core holders of all these embodiments can be used, and any of these can be employed as long as the shape can obtain the same effect.

According to the present invention, the pen core holder can be detached from the main body with an easy configuration and means, and the pen core holder can be replaced and the ink can be replenished.
