Abstract

(57) [Abstract] [Purpose] To provide a brush pen with a simple structure capable of writing both bold and thin characters with a single brush pen. [Structure] In a brush pen in which a tapered brush tip 3 projects from a tip opening 2 at the tip of a barrel 1 and ink in the barrel is supplied to the brush tip, an auxiliary cover 4 having a tip opening 41 at the tip 2 is provided. It is detachably fitted, the outer periphery of the brush tip 3 is brought into contact with the inner edge of the tip opening 41 of the auxiliary cover 4, and the tip end portion 3 of the brush tip 3 is attached.
A is projected from the front end opening 41 of the auxiliary cover 4, and the auxiliary cover 4 is removed when writing bold letters.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a writing pen that has a tapered brush tip made of a fiber bundle and is written with the same handwriting as a writing brush.

[0002]

[Prior art]

 The brush pen has a tapered brush tip made of fiber bundles protruding from the tip of the tip of the barrel, and the ink in the barrel is supplied to the brush tip to write with the same handwriting as a brush. Therefore, it is difficult to write both bold and thin letters with one brush pen, and a thick brush pen and a thin brush pen are required. For this reason, a double-headed brush pen in which a brush for thick letters and a brush for thin letters are attached to both ends of the barrel has been put into practical use.

[0003]

[Problems to be solved by the device]

 However, the two-headed brush pen has a problem that its structure is complicated. In addition, since the brushstrokes for bold letters and brushstrokes for thin letters are not used at the same frequency, one of the brushtips may become unusable first and may not function as a two-headed brush pen.

Therefore, an object of the present invention is to provide a brush pen that has a simple structure and is capable of writing both bold and thin characters with one brush pen.

[0005]

[Means for Solving the Problems]

 In order to achieve such an object, the present invention is a brush pen in which a tapered brush is projected from the tip of the tip of the barrel, and the ink in the barrel is supplied to the brush. The auxiliary cover is detachably fitted, the outer circumference of the brush is brought into contact with the inner edge of the tip opening of the auxiliary cover, and the tip of the brush is projected from the tip opening of the auxiliary cover.

[0006]

[Effect] That is, when the auxiliary cover is fitted to the front opening, only the tip of the tapered brush tip protrudes from the tip opening of the auxiliary cover, so it can be used as a fine writing brush pen. When the cover is removed, all brush tips protruding from the tip are exposed, so it can be used as a brush pen for bold letters. In other words, it is possible to write both bold and thin letters simply by adding an auxiliary cover to one brush pen.

【Example】

 The present invention will be described in detail below with reference to the embodiments shown in the drawings. In FIG. 1, a tip 2 is fixed to the tip of a barrel 1, and a brush tip 3 projects from the tip 2. The brush tip 3 is formed by bundling fibers into a taper shape. The protruding length from the front opening 2 is, for example, 9 mm, and the outer diameter at the base end is 4 mmφ. It is a thing. Then, the ink in the ink cartridge (not shown) housed in the barrel 1 is supplied to the brush tip 3 and can be written with the same handwriting as a writing brush.

As shown in FIG. 2, the auxiliary cover 4 has a conical cylinder part 42 integrally connected to the tip of a cylindrical part 44, and a cap fitting part 43 between the cylindrical part 44 and the conical cylinder part 42. Has been formed. The inner diameter of the tip opening 41 of the auxiliary cover 4 is, for example, 1.5 mmφ.

As shown in FIG. 1, the auxiliary cover 4 is fitted to the auxiliary cover fitting portion 21 of the front opening 2. The tip portion 3a of the brush tip 3 projects from the tip opening 41 of the auxiliary cover 4, but the outer circumference of the brush tip 3 contacts the inner edge of the tip opening 41, and the brush tip 3 from the tip opening 41. The protruding length of the tip 3a of the is 3 mm. Therefore, when the auxiliary cover 4 is fitted in the front opening 2, the auxiliary cover 4 functions as the front opening, and the tip portion 3a of the brush tip 3 protruding from the auxiliary cover 4 is for fine characters. Although the cap 5 is fitted in the cap fitting portion 43 of the auxiliary cover 4, the fitting resistance of the cap 5 to the auxiliary cover 4 is smaller than the fitting resistance of the auxiliary cover 4 to the front port 2. There is.

Then, when the cap 5 is removed from the auxiliary cover 4, as shown in FIG. 3, the tip portion 3a of the brush 3 projects from the tip opening 41 of the auxiliary cover 4, and fine letters can be written. Next, when the auxiliary cover 4 is removed from the front opening 2, as shown in FIG. 4, the entire brush tip 3 is exposed, so that bold letters can be written.

As described above, it is possible to write both bold and thin letters by simply adding the auxiliary cover 4 to an ordinary brush pen without using a double-headed brush pen. If the conical cylinder 42 of the auxiliary cover 4 is shortened and the inner diameter of the tip opening 41 is increased, it is possible to use it for middle characters between bold and thin.

[0012]

[Effect of device]

 As described above, in the brush pen of the present invention, the auxiliary cover having the tip opening is detachably fitted to the tip end where the tapered brush tip protrudes, and the outer periphery of the brush tip is covered with the tip opening of the auxiliary cover. Since it contacts the inner edge and the tip of the brush tip projects from the tip opening of the auxiliary cover, only the tip of the tapered brush tip projects from the tip opening of the auxiliary cover and is used as a writing pen for fine writing. Yes, but when the auxiliary cover is removed, all brush tips protruding from the tip are exposed, so it can be used as a brush pen for bold characters.
