(57) [Summary] [Purpose] To provide a writing instrument in which the cap body is not lost even when the writing instrument is used without inserting the cap body into the main shaft. [Structure] A cap body and a body shaft are integrally molded of soft plastic through a connecting band.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a writing instrument having a cap such as a ballpoint pen and a marking pen, and more particularly to a writing instrument with a cap formed by integrally connecting a cap body and a main body shaft.

[0002]

[Prior art]

 In conventional writing instruments of this type, the cap body and the main body shaft are separate bodies.When using the writing instrument, put the cap body on the tail end of the main body shaft or leave the cap body on a desk or the like. I often keep it.

[0003]

[Problems to be solved by the device]

 However, it is troublesome to put the cap body on the tail end of the main body shaft, and the cap body tends to be left alone, the cap body is lost, and the ink evaporates depending on the writing instrument. However, I was sometimes unable to write and had to discard my writing implements.

[0004]

[Means for Solving the Problems]

 The writing instrument with a cap according to the present invention solves the above-mentioned problems, and is one in which the cap body and the main body shaft are integrally connected by a bendable connecting band.

【Example】

 The present invention will be described in more detail with reference to the embodiments shown in the drawings. FIG. 1 shows a state in which a cap body 1 and a main body shaft 2 of a writing instrument with a cap according to the present invention are integrally molded with a soft plastic such as polyethylene or polypropylene via a connecting band 3. One end of a flexible connecting band 3 made of the same material is integrally attached to the outer surface of the cap body 1 made of, and the other end of the connecting band 3 is appropriately positioned on the outer surface of the main body shaft 2 made of the same material. It is integrally attached to the.

Then, when not in use, the cap body 1 is inserted into the front end of the main body shaft 2 as shown in FIG. 2, so that it is possible to prevent the pen tip from drying up, and when using a writing instrument. As shown in FIG. 3, the cap body 1 may be inserted into the tail end of the main body shaft 2, and when the writing is immediately stopped, the cap body 1 is not inserted into the tail end of the main body shaft 2. The cap body may be freely swingable, and in any case there is no need to worry about losing the cap body. Further, as shown in FIG. 4, by making the connecting band 3 into a spring shape having elasticity, the cap body 1 is detached from the main body shaft 2 when the writing instrument is used, and the cap body 1 is removed. Even if you write without inserting it on the tail end, the cap body 1 does not dangle so much that it does not interfere with writing.
