JPH0553990U - Writing instrument with cap - Google Patents

Abstract

(57) [Summary] [Purpose] A writing instrument using volatile ink can be easily written with one hand, and the cap body is connected to the barrel, so the ink will evaporate if the cap is lost. It does not become impossible to write. [Structure] Two pairs of projections 4 are provided on the front small diameter portion 3 of the shaft cylinder 2, and a vertically long through hole 9 is formed in the opening of the cap body 6 so as to face each other.
Two pairs of hanging pieces 7 having the same are provided, and the projections 4 are provided in the through holes 9.
It is made by fitting.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a writing instrument using a volatile ink such as a marking pen, and more particularly to a writing instrument with a cap that can easily remove the cap with one hand.

[0002]

[Prior Art]

 Conventionally, the cap of a writing instrument is often left as it is after being removed, or it is attached to the rear end of the writing body, and airtight is considered for writing instruments such as marking pens that use such volatile ink. For this reason, the cap was relatively tightly fitted to the writing instrument.

[0003]

[Problems to be solved by the device]

 However, if left unattended, the cap is inadvertently lost, the ink evaporates and it becomes impossible to write, and it takes time to write the cap on the rear end of the cursive body. It's annoying because it's gone. Furthermore, when one hand is blocked by luggage or the like and it becomes necessary to write characters on a slip etc., it is extremely difficult to remove the cap of the writing instrument, which is unhygienic, but the cap should be held in the mouth. It had to be removed, which was very inconvenient.

[0004]

[Means for Solving the Problems]

 The portable writing instrument according to the present invention solves these problems, and has two pairs of protrusions on the front small diameter portion of the barrel, and a vertically extending through hole that faces each other at the opening of the cap body. Two pairs of pieces are similarly provided, and the projections are fitted into the through holes.

[0005]

[Action]

 With such a structure, by pushing the cap body upward and tilting the cap body sideways, the pen tip appears and the writing state becomes possible.

[0006]

【Example】

 The present invention will be described in more detail with reference to an embodiment shown in the drawings. FIG. 1 shows a state in which the cap body is not attached to the pen tip of the writing instrument with a cap according to the present invention, and is provided in front of the barrel 2 having the pen tip 1 such as a marking pen at the tip. The protrusions 4 are provided on both side surfaces of the small diameter portion 3 and the hanging pieces 7 facing each other are integrally projected at the opening of the cap body 6 having the inner cap 5. An annular rib 8 into which the inner cap 5 is fitted is provided at the front end of the small-diameter portion 3 of the shaft cylinder 2 so that the cap body 6 is firmly fixed to the shaft cylinder 2 and the pen tip is Airtight of 1 is perfect. Each of the hanging pieces 7 is formed with a vertically long through hole 9, and the through hole 9 is slidably fitted into the projection 4 by the cap body 6. Then, when using, as shown in FIG. 2, by pressing the cap body 6 with a fingertip, the cap body 6 slides upward, and then the head of the cap body 6 is laid down sideways around the protrusion 4. As a result, the pen tip 1 is exposed and is ready for writing. Next, when writing is completed, the cap body 6 which is lying down is raised upward, and the top of the cap body 6 is pressed toward the barrel 2 so that the inner cap 5 is annular at the tip of the barrel 2. It is fitted to the rib 8 and returns to its original state.

[0007]

[Effect of the device]

 As described above, the writing instrument with a cap according to the present invention can easily write with the pen tip protruding from the tip of the barrel with one hand even when one hand is blocked by luggage or the like. It is very convenient as a writing instrument, and since the cap body is not lost, the ink does not evaporate and writing becomes impossible.
