Description

[Detailed Description of the Invention] (Field of Industrial Application) This invention mainly belongs to the field of writing instruments such as ballpoint pens, sharp pencils, and fountain pens.

(Prior art) The present invention was originally filed by the applicant in 1983.
This relates to improvements to No. 85864 (filed on June 5, 1985).

(Technical Problem) The technical problem of this invention is to prevent the seal body housed in the writing instrument body from flying out and falling when the cap body is pulled out from the writing instrument body. It is.

(Technical Means) In order to solve the above-mentioned technical problem, the present invention provides a storage tube with an opening inside the writing instrument body, and a stamp body such as a rubber stamp having a knob that can be raised and lowered is placed inside the storage tube. It is designed to be stored, and also to prevent the stamp body from flying out due to the attraction force of the magnet and the stopper part. Specifically, as shown in the illustrated embodiment, the configuration is as follows.

1 is a writing instrument body, and a ballpoint pen is shown.

Reference numeral 2 denotes a storage cylinder having an opening 3 provided in the writing instrument main body 1, and an ink mat 4 is placed at the bottom of the storage cylinder.

Reference numeral 5 denotes a stamp body such as a rubber stamp 7 having a knob 6 that can be raised and lowered, and is designed to be placed and stored in the storage tube 2. 8 is a bearing into which the shaft 9 of the knob 6 is loosely fitted. Reference numeral 10 denotes a coil spring wound around the shaft rod 9, so that when the knob 6 is attached to the bearing 8 via the shaft rod 9, the knob 6 always stands up in the direction of arrow A due to the elasticity of the coil spring 10. It has been done.

Reference numeral 11 denotes a cap body, and when sliding the cap body in the direction of arrow B and fitting it into the housing tube 2, the knob 6 of the stamp body 5 stored in the housing tube 2 is pushed against the elasticity of the coil spring 10 to move it to arrow C. It can be forced to lie down in any direction.

Furthermore, when the cap body 11 is pulled out in the direction of arrow D, the knob 6 automatically stands up in the direction of arrow A due to the elasticity of the coil spring 10.

Reference numeral 12 is a penetrating seal that is removably attached to the top of the cap body 11, and uses the type disclosed in Utility Model Application No. 58-140785. A stamping member having micropores impregnated with vermilion liquid is sequentially laminated together with a cushion member. 13 is a lid body.

Reference numeral 14 is a metal frame constituting a part of the seal main body 5, and a stopper portion 15 is provided at one end in the longitudinal direction.
is made to protrude in the horizontal direction, and a bending stopper portion 16 is also formed protruding from the other end. 17 is a bent surface. A magnet 18 is fixed to the vertical wall surface 19 of the housing cylinder 2, and is arranged to face the bending surface 17 of the bending stopper portion 16.

When the seal main body 5 is stored through the opening 3 of the housing cylinder 2, the seal main body 5 is folded into the bending stopper part 16.
It is attracted and held by the magnet 18 via the bent surface 17 of.

Reference numeral 20 is an upper stop edge of the housing cylinder 2 and is designed to abut the stopper portion 15.

21 is also formed so as to abut the bent stopper portion 16 at the upper stop edge of the magnet attachment side of the housing cylinder 2. Therefore, even if an attempt is made to pull out the seal body 5 directly above, it will not come off.

22 is a ballpoint pen core.

(effect) The above technical means works as follows.

As shown in FIG. 6, when the cap body 11 is pulled out in the direction of arrow D, the knob 6 of the stamp body 5 housed in the housing tube 2 stands up in the direction of arrow A due to the restoring elasticity of the coil spring 10. At this time, since the bending surface 17 of the bending stopper part 16 of the stamp main body 5 is attracted by the magnet 18, the stamp main body 5 as a whole is attracted and moved in the direction of the arrow E, and the bending stopper part 1
6 is brought into contact with the stop edge 21 of the housing cylinder 2, and the stopper part 15 is brought into contact with the stop edge 20 of the housing cylinder 2.
Since the stamp body 5 is in contact with the opening 3, the stamp body 5 will not fly out or fall from the opening 3. Next, the entire seal body 5 is slightly shifted in the direction of the arrow F using the knob 6 which is standing up, and the bent surface 17 is separated from the magnet 18.

At this time, the bending stopper part 16 also comes off from the stop edge 21, so next, the bending stopper part side of the stamp main body 5 is pulled out diagonally in the direction of arrow G, and the whole stamp main body 5 can be taken out.

Also, when storing it, you can perform the operation opposite to the above.

(Effects) The present invention has the following unique effects.

During the act of pulling the cap out of the writing instrument body,
Furthermore, even if the writing implement body is turned upside down with the cap removed, the seal body will not fly out or fall off, and there is a great effect in that it is possible to prevent the seal body from being lost, damaged, or soiled.
