Abstract

(57) [Summary] [Purpose] The decorative effect can be exhibited without changing the structure of the writing instrument itself, which is attractive, has a good feel, and does not feel tired even when used for a long time. In a knock-type writing instrument with a cap 4 attached to a main body 1, a concave surface is formed in the center of the cap 4, and the concave surface is formed so that most of the spherical surface portion protrudes from the cap 4.
Fix the rule 5.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pal knock type writing instrument in which a writing instrument projects from a main body when a pal attached to a cap is knocked.

[0002]

[Prior art]

 Most of the sharp pens are of the knock type in which the upper end of the cap on the main body is pressed with the thumb in order to make it easier to project and retract the pen core at the tip of the writing part. Many have adopted. Since the cap in this case does not cover the writing part like a fountain pen, it can be removed only when using the eraser or inserting the pen core in the sharp pen, and the ball is not removed. The pen is usually disposable except for special cases, and has a structure in which the cap is not removed.

[0003]

[Problems to be solved by the device]

 The body and cap of the above-mentioned knock-type writing instrument have a series of appearances, and most of them have the same color as the body and the cap shape is simple, and the cap head against which the thumb abuts is rounded or flat. There is a difference in that it is formed on the surface, but it is easy to get tired because it has little change and is dry and tasteless, and since the feel on the thumb is not taken into consideration, it feels tired when used for a long time. There was a problem.

The present invention has been made in view of the above circumstances, and can exert a decorative effect without changing the overall shape and color, and can be used with amusement, so that it can be used without being tired for a long time. At the same time, it is intended to provide a writing instrument that does not feel fatigue because it has a good feel and moderate stimulation.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention comprises a body into which a shaft cylinder containing ink or a pen core is inserted, and a cap engaged to the upper part of the main body. When the cap is pushed, the shaft cylinder tip or the pen core becomes the main body. The main purpose of the writing instrument that protrudes more is to form a concave surface in the center of the upper end of the cap, and to fix the concave surface to the par so that most of the spherical surface projects from the cap.

[0006]

[Action]

 Most of the pal stuck to the upper end of the cap is prominent because it protrudes from the cap, and the bright color peculiar to the pal is visually observed to make the cap stand out. Then, when the thumb is pressed against the pal, the fingertips receive an appropriate stimulus, the cap is pushed down, and the barrel in the main body descends, so that the barrel barrel tip or the pen core tip is removed. Writing is possible by protruding from the main body. The par is always on the top edge of the cap during and after writing, so it is constantly visible.

[0007]

【Example】

 FIG. 1 shows an embodiment in which the present invention is a ball-point pen, and 1 is a main body into which a shaft cylinder 2 filled with ink 3 is inserted. When the button is pressed, the barrel 2 is pressed and the tip of the barrel projects from the main body 1. This point is no different from the conventional ball-point pen.

Reference numeral 5 is a pal fixed to the upper surface of the cap 4 and having a diameter of about 4 to 5 mm. The type of the pal 5 is not limited, but since the pearl is expensive, a shell pallet or a synthetic resin-made pallet is usually used.

FIG. 2 shows a state in which the par 5 is fixed, in which a concave surface 6 is formed at the center of the upper end of the cap 4, and the par 5 is fixed to the concave surface 6 using an adhesive (not shown). To do. The concave surface 6 and the outer surface of the pall 5 are in close contact with each other, and both are strongly fixed via an adhesive, so that the pall 5 is unlikely to escape from the concave surface 6 even if an external pressure is applied. The par 5 partially contacts the concave surface 6, and most of the spherical surface portion projects from the cap 4.

Although not shown, since a spring is attached to the inner surface of the cap 4, the cap 4 is lowered when the par 5 is pushed with a fingertip, and is returned when the finger is released. Further, the shaft tube 2 is interlocked with the cap 4, and the tip portion 2'which is a ball is projected and retracted from the main body.

FIG. 3 shows an embodiment in which the present invention is a sharp pen, in which a concave surface 6 is formed at the center of the upper end of a cap 4 engaged with the upper portion of the main body 1, and a par 5 is glued to the concave surface. It is fixed by using, and most of the spherical surface of the par 5 projects from the cap 4. In the sharp pen, when the pen core 3a is put in the shaft cylinder 2 in the main body 1 and the pal 5 is pushed, the shaft cylinder 2 moves and the pen core 3a projects from the tip of the main body 1. In this case, the structure of the sharp pen itself does not differ from the conventional one.

[0012]

[Effect of device]

 The present invention as described above has the following effects. (1) Since the pearl fixed to the upper end of the cap develops a unique brilliant color and brings a remarkable decorative effect to the writing instrument, even if the body and the cap are the same color and are not conspicuous, the writing instrument is beautiful and looks good. It will be good. (2) Since most of the spherical surface of the pall protrudes from the upper end of the cap, when knocked, the fingertips come into close contact with the outer surface of the pall and receive a moderate stimulus, providing a good feeling and activation of the fingertips, and fatigue. It's good for your health because you don't feel it. (3) The writing instrument itself has the same shape as the conventional one, and since it is only necessary to perform a processing work to form a concave surface for fixing the pal on the upper end of the cap, it is possible to provide the product at a low cost because there is no trouble. (4) Since the pal is always exposed, it can be used effectively for a long time without getting tired because it is handled with a sense of interest and both during writing and after writing.
