Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a writing instrument, and more specifically, to a disposable writing instrument that resembles a fountain pen.

[Conventional technology]

Currently, there are various types of writing instruments on the market,
The most luxurious of these is the fountain pen.
Its luxurious feel is largely due to the structure of the nib, and it is significantly different from other writing instruments, especially disposable writing instruments, which have different nib structures.

[The problem that the idea attempts to solve]

As mentioned above, in the case of conventional disposable writing instruments, it has been difficult to create a luxurious feel like a fountain pen.

Therefore, the object of the present invention is to provide a disposable writing instrument that has a shape similar to a normal fountain pen, has good writing comfort, has a simple structure, and can be supplied at a low price.

[Means to solve the problem]

In the present invention, a core material 2 impregnated with ink is inserted into a cylinder shaft 1 having a cylindrical shape or other suitable shape, and the opening side of the cylinder shaft 1 is narrowed to reduce its diameter, and therein,
A metal pen tip 3 has a shape similar to the nib of a fountain pen and is equipped with an ink slit that extends to the nib, and has an absorber 4 in close contact with the back side that guides the ink impregnated into the core material 2 to the slit.
The above problem was solved with a writing instrument made by press-fitting.

[Effect]

Since the metal pen tip 3 has a shape approximating the nib of a fountain pen, a high-quality disposable writing instrument can be obtained. The ink impregnated into the core material 2 is guided to the pen tip via the occlusion body 4.

〔Example〕

A preferred embodiment of the present invention will be described with reference to the drawings. In the figure, numeral 1 is a hollow body shaft with an open end, and the opening side is narrowed down to form a reduced diameter portion 1a. Air holes are provided in the trunk shaft 1 as appropriate. Reference numeral 2 denotes a core material inserted into the barrel shaft 1, which is impregnated with ink commonly used for felt-tip pens and the like. 3 is a metal pen tip, the front side of which has a shape approximating the nib of a normal fountain pen, and a slit for guiding ink to the nib. An occlusion body 4 that sucks up ink impregnated into the core material 2 and guides it to the slit of the metal pencil tip 3 is closely attached to the back side of the metal pencil tip 3. However, in the case of this writing instrument, unlike a fountain pen, the ink in the tank is not sucked up as it is, but the ink that is impregnated in the core material 2 is sucked up, so the occluding body 4 is not as complex as the occluding body of a fountain pen. It does not need to be in the shape of a fin, but may be a simple semi-cylindrical shape or the like. Therefore,
The structure is simple and easy to assemble, and the price can be kept low. The occlusion body 4 is manufactured, for example, by resin molding or thermoforming fibers, by forming open cells with a polymeric material, or by using felt or the like. Incidentally, in order to bring the occluding body 4 into close contact with the metal pen tip 3, a plastic auxiliary member may be used. 5 is a cap.

The writing instrument according to the present invention is used like a normal writing instrument by removing the cap 5. Then, when the ink runs out, throw it away.

[Effect of idea]

The present invention is as described above, has a shape similar to a fountain pen, provides a writing feel similar to a fountain pen, has a high-class image for a disposable type, and is inexpensive due to its simple structure and easy assembly. It has the effect of being able to be mass-produced and supplied.

Claims (1)

[Scope of utility model registration request] A core material 2 impregnated with ink is inserted into a barrel 1 of a cylindrical shape or other appropriate shape, and the opening side of the barrel 1 is narrowed down to reduce its diameter, and a nib shape approximating that of a fountain pen is placed there. The core material 2 is provided on the back side with an ink slit extending to the pen tip.
A writing instrument comprising a metal pen tip 3 which is press-fitted with an occlusion body 4 that guides ink impregnated into the slit into the slit.
