Description

[Detailed description of the invention] The present invention provides a new structure for a marking pen that is equipped with a tank containing spare ink to replenish the ink stored in the filling when it runs out. A stepped section in which a double-cut ink absorbing body, which is made by covering a soft synthetic resin pipe on a cotton batting and absorbing ink into the batting, is loaded into a shaft cylinder, and its tip is provided inside the coaxial tube. At the same time, a felt pen nib is inserted from the outside into the nib of the barrel, and its inner end is pierced into the above-mentioned batting. The small diameter part of the small tank is fitted into a cylindrical push-in part provided on the front surface of the rear cover, and the push-in part of the rear cover is inserted into the back cover. The gist is to press fit into the coaxial cylinder from the tail end of the cylinder, engage its outer surface with the inner edge surface of an inward flange provided at the rear end of the cylinder, and insert a small tank into the tail end of the ink storage body. It is something.

In the embodiment shown in FIGS. 1 and 2, a pipe 2 made of a soft synthetic resin is attached to a filling 1 made of synthetic resin crimped fiber sliver having a density that allows capillary action to occur efficiently, and ink is applied to the filling 1. It absorbs moisture to form a double-cut ink storage body 3, and this ink storage body 3 is loaded into a shaft cylinder 4, and its tip is locked to a stepped portion 5 provided in the coaxial cylinder 4, and the shaft cylinder is A felt pen nib 7 is inserted from the outside into the nib part 6 of 4, and its inner end is pierced into the filling 1, and separately cut off to open the opening part 9, the narrow diameter part 10, and the thick part. A small tank 12 containing preliminary ink formed by the diameter portion 11
The small diameter part 10 of this small tank is connected to the rear lid 1.
3, the push-in part 14 of the rear cover 13 is press-fitted into the coaxial cylinder 4 from the rear end of the shaft cylinder 4, and its outer surface is inserted into the rear end of the shaft cylinder 4. The small tank 12 is inserted into the tail end of the ink storage body 3, and the small tank 12 is fitted with a screw cap. 16, and when the storage ink in the batting 1 runs out, the rear cover 13 is removed and the small tank 12 is taken out along with it, and then this small tank 12 is removed from the rear cover 13. At the same time as removing it, cut off the mouth 9 of the small tank 12 and remove the screw cap 16 to open it.
Thereafter, the small tank 12 is turned in the opposite direction and stored inside the rear end of the pipe 2 again, and the rear cover 13 is
By closing the small tank 12, the ink inside the small tank 12 can be replenished into the batting 1.

As mentioned above, when the ink runs out, the present invention can be refilled from its own tank, which is of course convenient.
In particular, in the present invention, a small tank containing preliminary ink is formed by a narrow diameter part facing the mouth and a large diameter part, and the small diameter part of this small tank is provided in a cylindrical shape in front of the rear lid. After this, the push-in part of the cover is press-fitted into the coaxial cylinder from the tail end of the shaft cylinder, and its outer surface engages with the inner edge surface of the inward flange provided at the rear end of the shaft cylinder. Since the tank is inserted into the tail end of the ink storage body, with the rear cover and ink tank integrated, the ink tank can be inserted into the tail end of the ink storage body and the rear cover can close the shaft cylinder tail end all at once. Not only can the rear cover be removed from the tail end of the shaft cylinder, but also removed from the ink tank storage body in the same way.
-These operations can be performed more easily and quickly than in the case of the method described in Publication No. 17335, in which fitting and removing the ink tank to the tail end of the ink storage body and attaching and detaching the rear cover to and from the shaft cylinder are performed separately. effective.
