KR20170088257A - Sharp Pencil Containing Migwish Roller - Google Patents

Abstract

The present invention relates to a mechanical pencil including an eraser powder roller. According to the present invention, the mechanical pencil includes: a body (10) including a cylindrical lower part to be inserted into the mechanical pencil through the rear surface thereof; a cylindrical plastic rod (11) fitting a roller to the body (12); a flat plastic plate (12) coming in contact with the roller to scrap off the eraser powder; a plastic roller (20) capable of fixing the rod (11) to rotate; a belt (30) which is formed on the surface of the roller (20) to be rotated; and a cover (40) which is assembled with the body (10) to be opened and closed. The mechanical pencil can enhance cost efficiency and eliminate the need for spending money and purchasing new stickers after using all of stickers purchased in advance. The mechanical pencil can maintain always the same adhesion force unlike the stickers having reduced adhesion properties due to eraser powder attached thereon during use while preventing a user from exposing other parts of the surface of new stickers due to the reduced adhesion properties of the used stickers. The present invention enables the eco-friendly usage of the mechanical pencil without generating excessive waste other than the eraser powder. The mechanical pencil uses the roller to be used on a semi-permanent basis unlike a conventional mechanical pencil needing new sticker replacements upon using all of adhesion stickers for the eraser powder.

Description

Sharp Pencil Containing Migwish Roller with Eraser Powder Roller

The present invention relates to a mechanical pencil having an eraser powder roller, and more particularly, to a mechanical pencil having an eraser powder roller which allows the eraser powder adhered to the roller to be scraped off the jaw and stored in a pail.

Generally, when using an eraser, an eraser powder was generated.

However, the generated eraser powder interfered with the handwriting, and there was a problem that it was inconvenient to collect the powder together.

This has led to the development of a sharp pencil having an eraser powder handling sticker, but this also has some problems.

The conventional pencil having a sticker for eraser flour treatment has a problem in that the sticking force is adhered to the sticker as time elapses.

In addition, the mechanical pencil having the eraser powder handling sticker has to disassemble the sticker every time the sticking force is deteriorated, so that the new sticker surface must be exposed so that inconvenience arises

On the other hand, the mechanical pencil having the eraser powder handling sticker has a problem that when the use of the sticker is completed, the user can not use the sticker any more unless he / she wears a new sticker.

In addition, there is a problem that the sharp pencil having the eraser dust handling sticker adversely affects the environment because the sticker used as a consumable article is turned into garbage.

Therefore, there is a need for a more environmentally friendly improvement of the pencil having the eraser powder sticker with low efficiency and durability of the sticker.

Korean Registered Patent No. 10-1219209 (December 31, 2012)

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems occurring in the prior art,

An object of the present invention is to provide a mechanical pencil having an eraser powder roller capable of continuously collecting eraser powder in a cylinder by means of a roller.

In order to achieve the above object, the present invention provides a pencil having an eraser powder roller,

A body 10 having a cylindrical shape at the bottom so as to be inserted into the rear surface of the mechanical pencil;

A cylindrical plastic rod 11 capable of assembling the roller 20 and the lid 40 to the body 10;

An end sloping plastic flat plate (12) capable of contacting the roller (20) with the body (10) and scraping off the powder;

A plastic plate 13 formed on the body 10 and capable of holding the eraser powder in a predetermined space;

A plastic roller (20) fixed to the rod (11) and rotatable;

A belt (30) formed on the surface of the roller (20) and rotatable;

And a lid (40) assembled to the body (10) and capable of being opened and closed.

The present invention has an economical effect in that if the sticker is used in its entirety, it is not necessary to spend the time to purchase a new sticker,

In addition, since the eraser powder adheres to each other due to the use of the sticker, the adhesive force of the sticker is reduced and the adhesive force can be maintained constantly.

In addition, when the sticker is used once, the absorbing power is reduced and the consumable application, which is required to expose the surface of the new sticker, is removed, so that there is no environmentally-friendly effect except for the eraser powder.

Particularly, the present invention has the effect of being used semi-permanently by using the rollers by avoiding the one-time use of replacing the sticker of the present invention with a new sticker every time the sticker of the mechanical pencil having the eraser powder sticker is consumed.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a front view for illustrating the structure of a mechanical pencil having an eraser powder roller of the present invention.

Technical features of the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows a front view for illustrating the structure of a mechanical pencil having an eraser powder roller according to the present invention.

In the present invention, two rods (11) are coupled to the inside of the body (10) and extend from one inner surface to the other inner surface.

On the other hand, a hole through which the rod 11 passes can be formed in the center of the side surface of the two rollers 20 so that the roller 20 can freely rotate while being inserted into the rod 11 of the body have.

At this time, the surface of the two rollers 20 can be freely rotated in contact with the outer surface of the roller 20 by hanging the belt 30 on the surfaces of the rollers 20.

In the body 10, the inclined flat plate 12, which is in contact with the surface of the belt 30, is formed at an upper portion of an inclined portion in a direction opposite to the advancing direction of the belt 30, The belt 30 can be scraped off.

The flat plate 13 is formed on the side opposite to the inclined flat plate 12 and is horizontally disposed with a slight space therebetween so that the scraped eraser powder can fall into the inner space formed by the flat plate 13 when the sharp pencil is directly erected Respectively.

Two bars 11 formed on the lid 40 are assembled to the body 10 at a portion corresponding to the inner space formed by the flat plate 13. The lid 40 is formed to be openable and closable to the outside.

Therefore, the present invention can easily collect the eraser powder adhered to the belt 30, and it is not necessary to periodically replace the eraser powder, so that convenience in use can be increased.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.
