SOLUTION: When a cap 16 of the cartridge is opened and separated from a cartridge barrel 14, the core cotton 10 can be taken out from the cartridge barrel 14, in a state of sticking to the cap 16, since the core cotton holding force (force of holding the core cotton between) of ribs 28 of the cap 16 is larger than that of ribs 26 of the cartridge barrel 14. After the core cotton 10 is extracted from the writing implement, accordingly, a fresh core cotton can be fitted in the barrel of the implement, with the cap held.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cartridge for accommodating batting, which accommodates batting for storing ink or coating liquid such as a writing instrument or an applicator.

[0002]

2. Description of the Related Art A writing instrument is one in which ink is placed on a writing surface such as a paper surface with a writing tip portion at the tip of the writing instrument main body or a pen tip. There are two types of ink storage parts to be stored inside, a batting type in which ink is impregnated into a fibrous body (ink storage body) and a raw ink type in which raw ink is stored in a tank. Here, the batting type storage unit has a batting exchange structure in which the ink is exchanged for a new ink cartridge after the ink is used, and a writing instrument of that kind is called an batting exchange type writing instrument. In the batting exchangeable writing instrument, the body of the writing instrument main body cylinder is screwed, and the body is opened by turning the screw to take out the used batting (cartridge), and then attach the unused batting to the body. It is fitted so that the body is closed.

[0006] Such a batting pad type writing instrument uses a container (cartridge shaft) for hermetically storing unused batting. As shown in FIG. 5, the batting a is housed in the cartridge shaft b, and a cap c is fitted and sealed at the mouth of the cartridge shaft b. When the cap c is removed from the cartridge shaft b when the batting a is replaced, the cap c is usually pulled in the longitudinal direction from the cartridge shaft b to open the fitted seal portion d and remove the cap c. There is. In the cartridge, the cap c and the cartridge shaft b are provided with a concavo-convex portion in the circumferential direction of the fitting portion as the seal portion d so that the gas in the sealed cartridge does not expand and float the cap c due to the temperature rise. , There is a catch to prevent it from coming off. As described above, the batting inside the writing instrument main body is used as an ink storage part.In a batting type writing instrument with a structure that discards the used batting and puts it in a new batting, the ink to be replaced is filled. The filling is sealed and held in the housing of the hollow barrel.

[0004]

By the way, if the writing instrument is used sufficiently for writing and the ink of the batting is used up, the writing cannot be performed, and therefore the batting needs to be replaced to replenish the ink. In this case, open the writing instrument shaft,
After discarding the used batting, install a new large amount of ink-filled batting in the shaft. In the past, when removing a new batting from the cartridge, the cap was removed from the cartridge shaft and the batting was taken out, but in that case, you would have to replace the batting containing a large amount of ink by hand. The ink may ooze out and get dirty on the fingers or the surroundings.Replacement of the batting requires relatively skill such as attention and dexterity of the hands, and anyone can easily fill the batting without worrying about dirt. There was a problem that it was not exchangeable.

The present invention has been made by paying attention to the above-mentioned problems of the prior art, and when the batting is replaced by completely using the ink of the batting type writing instrument or applicator, it is contaminated with fingers and the surroundings. It is an object of the present invention to provide a batting cartridge for storing batting that anyone can easily replace the batting without worrying about dirt.
