Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to the structure of a writing pen or a cosmetic pen having an ink core.

[0002]

2. Description of the Related Art A pen having an ink core, that is, a structure of a ballpoint pen or a felt-tip pen is used in both a writing pen and a makeup pen. The base for the ink is stored in the base.

Without exception, the ink core is oriented in the direction of the central axis of the main body even at the tip portion and is accommodated in a substantially linear shape.

However, both for writing and for cosmetics, it is not uncommon for the user, and especially for foreigners in the Arabic-speaking world, to use the writing instrument in an extremely tilted state (in a lying state).

When the writing pen or the makeup pen of the prior art in which the ink core has a substantially linear shape is used while being extremely tilted as described above, the ball caulking outer peripheral edge in the ballpoint pen structure and the felt-tip pen. The side of the protective pipe in the structure comes into contact with the contact portion (paper in the case of a writing pen, skin in the case of a makeup pen) first so that the tip of the ink core cannot always come into contact with the contact portion. Therefore, there is a defect that writing or makeup marks are faded.

Further, in the case of a writing pen that is written with an extremely tilt, writing may not be possible, while in the case of a makeup pen, it may be extremely tilted with respect to the front mirror. This may occur even if the cosmetic pen is in a state in which it is easily reflected along the axial direction of the main body, and the tip portion of the cosmetic pen and the contact portion of the face are extremely difficult to see.

[0007]

DISCLOSURE OF THE INVENTION The present invention overcomes the drawbacks of the writing pen and the cosmetic pen according to the prior art as described above, and the writing pen or the cosmetic pen in which the tip of the ink core is inclined. It is an object to provide a pen configuration.

[0008]

In order to solve the above-mentioned problems, according to the structure of the present invention, a part or the whole of the tip side of the mouthpiece located at the tip of the main body is predetermined with respect to the central axis direction of the main body. The writing pen or makeup based on the fact that the tip portion of the ink core inserted through the main body and the base is inclined with respect to the central axis direction by engaging with the main body in a state of having the inclination angle of It consists of a pen.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION As is clear from the description of the means for solving the above problems, the present invention is directed to a main body with a part or all of the tip side of the mouthpiece inclined with respect to the axial direction of the main body. The basic configuration is such that the tip of the ink core housed in the main body and the cap is also inclined with respect to the axial direction by being attached to.

There is no particular restriction on the specific method of attaching the tip end side of the mouthpiece to the main body in an inclined state, but it is left to the design of those skilled in the art. Due to the inclined structure at various tip positions,
Even when the main body is used in an extremely tilted state, the tip and the tip portion of the ink core 1 housed inside the base are set at a considerable angle as shown in FIG. In the case of (1), since it usually comes in contact with paper, and in the case of a cosmetic pen, it touches the human skin), the drawbacks and problems as described in the prior art cannot occur.

A description will be given below in connection with an embodiment.
