Description

  The present invention relates to a rod shape used for a user to cut out the tip of a rod-shaped drawing material into a specific shape when drawing a thin line on the skin or other drawing object using an eyebrow, eyeliner or other rod-shaped drawing material. The present invention relates to a shaving machine for a drawing material.

As a conventional rod-shaped drawing material shaving machine, one that cuts the tip of the rod-shaped drawing material into a conical shape with a sharp point by a rotational motion has been common. However, in the case of a conical rod-shaped drawing material, the tip is immediately rounded with use and it becomes impossible to draw a thin line, so it is necessary to frequently cut out the rod-shaped drawing material. In recent years, therefore, there has been used a rod-shaped drawing material sharpener capable of cutting a rod-shaped drawing material into a flat sword shape (carved sword shape) that does not require frequent cutting (see, for example, Patent Document 1). ).

There is also a cause for complicating drawing performed using a rod-shaped drawing material.

  SUMMARY OF THE INVENTION Accordingly, the present invention provides a rod-shaped drawing material scraper that allows a user who does not have a special skill to cut the tip of the rod-shaped drawing material into a desired specific shape in a short time. Accordingly, it is an object to facilitate drawing performed using a rod-shaped drawing material.

That is, the invention according to claim 1 is a sliding member having a sliding surface on the upper side for sliding in the front-rear direction by applying the tip of the rod-shaped drawing material, and a blade edge directed to the front side is a sliding surface. The sliding surface is provided at the slightly higher position so as to face the rear edge of the sliding surface, and has a continuous surface on the upper side that allows continuous sliding from sliding performed on the sliding surface. A scraper for a rod-shaped drawing material provided with a blade that cuts the tip of the rod-shaped drawing material into a predetermined shape through sliding performed over a continuous surface, the inner angle of which the sliding surface is an acute angle in front view The tip of the rod-shaped drawing material is cross-sectionally viewed from the front by forming the blade into a folded plate shape that is V-shaped similar to the sliding surface when viewed from the front. It is possible to cut into a cutting edge shape.
Here, the V shape is sufficient as long as it can achieve the purpose of cutting the tip of the rod-shaped drawing material into a cross-sectional cutting edge shape in a front view that does not require frequent cutting. The shape is not limited to the V shape formed as a straight shape, and includes a V shape formed by including a slight curved shape on the slope portion.
According to such a rod-shaped drawing material sharpener, a V-shaped sliding surface capable of cutting the tip end portion of the rod-shaped drawing material into a cross-sectional cutting blade shape in a front view and a V-shaped blade similar thereto. Since it has what has a continuous surface that continues from the sliding surface, the user who does not have special skills makes the tip of the rod-shaped drawing material into a desired specific shape through sliding performed from the sliding surface to the continuous surface It is possible to reliably perform the scraping operation in a short time, thereby facilitating the drawing performed using the rod-shaped drawing material.

In such technical means, as a guarantee of the minimum sharpness, from the viewpoint of surely performing the work of cutting the tip of the rod-shaped drawing material into a desired specific shape in a shorter time, the blade The cutting blade is preferably a single blade having a blade back on the upper side.
In addition, considering the characteristics of the soft rod-shaped drawing material, considering that it is not always necessary to adopt a metal blade, from the viewpoint of obtaining a sufficient effect of reducing the manufacturing cost through the reduction of the number of parts In this case, it is preferable that the sliding member and the blade are integrally formed of the same material.
Furthermore, from the standpoint of supplying higher value-added products to the market by incorporating this shaving tool into a container that can contain shavings inside, the sliding surface is shaved at the upper end face. It is formed on the front side of the slit of the upper end surface of the container that has a slit for dropping trash and has a receiving portion for storing the shavings dropped through this slit, and the continuous surface is the slit of the upper end surface of the container. It is preferably formed on the rear side.
