AI Technical Summary

Technical Problem

Existing technologies fail to prevent the whiteboard erasers from ink over time, and the dirt transfers to the dirt transfers to the dirt transfers to the dirt transfers to the dirt transfers to the dirt transfers to the dirt transfers to the dirt transfers to the dirt transfers to the dirt transfers to the dirt transfers to the dirt transfers to the dirt.

Method used

The eraser has an erasing surface on each hexagonal prism. The eraser has an erasing surface on each hexagonal prism. The eraser has an erasing surface on each hexagonal prism. The eraser cover is made by removing one side of the hexagonal prism and shortening the cut edges on both sides, exposing the eraser surface and allowing the new eraser surface to be used. To change the eraser surface, press the side of the eraser body and remove it from the side of the cover. Then rotate the eraser and insert it back into the cover to expose the new surface.

Benefits of technology

The eraser effectively prevents the erasing surface from becoming dirty, keeping the hands clean and maintaining the whiteboard cleanliness by storing the dirty side in the cover.

Abstract

When the number of uses of the whiteboard eraser increases, dirt adheres to the whiteboard. It is necessary to purchase a new one each time.SOLUTION: Multi-surface use: Since there are six erasing surfaces and a new surface can be used by extracting the main body from the cover, rotating the dirty surface, and inserting it into the cover, the eraser can be used for a long period of time. Simple structure: The structure is simple and the manufacturing cost can be suppressed. Protective case: The eraser main body is protected by being housed in a case, and the hand is prevented from being soiled by the surface used. In addition, the case can be reused and can be said to be ecological by replacing only the eraser portion of the contents. By this constitution, the use period of the white board eraser is extended and the disposal frequency thereof is reduced and the eraser can be expected as an ecological product.

Description

[Technical Field]

[0001] The present invention relates to a whiteboard eraser having a hexagonal shape. [Background technology]

[0002] A drawback of whiteboard erasers is that the erasing surface becomes dirty with ink over time, and the dirt transfers to the whiteboard each time it is used. Improved versions of whiteboard erasers exist, with multiple layers of cloth for the erasing area attached with Velcro, but they are thick and difficult to erase.

[0003] As an improvement, this eraser has an erasing surface on each hexagonal prism. The eraser cover is made by removing one side of the hexagonal prism and shortening the cut edges on both sides, exposing the eraser surface and allowing the new eraser surface to be used. To change the eraser surface, press the side of the eraser body and remove it from the side of the cover. Then rotate the eraser and insert it back into the cover to expose the new surface. In addition, the dirty side of the eraser is stored in a cover, so your hands won't get dirty. [Brief explanation of the drawings] [Figure 1] Diagram of the case. The case is hexagonal, with only one side that fits on the whiteboard being shorter. [Figure 2] A diagram of the eraser itself. The eraser cloth is wrapped around a hard hexagonal sponge. [Figure 3] The eraser body is inserted from the side and placed in the cover. The eraser body is stored in the case. [Figure 4] A side view of the eraser, showing the cover, the cross-sectional shape of the eraser, and how the fabric is wrapped. [Figure 5] An image of how it works, showing the eraser being held in the hand and erasing the whiteboard.

Claims

1. This whiteboard eraser is characterized by the fact that the eraser part and cover are shaped like hexagonal pillars, allowing a new eraser surface to be used six times.

2. By removing one side of the eraser cover and shortening both sides of the cut edge, the eraser is exposed.

3. The eraser can be removed by sliding it sideways against the cover.
