AI Technical Summary
Existing chalk boxes are prone to breaking chalk during transportation, and cannot effectively summarize and avoid the color-stringing problem between different colors of chalk.
A multi-functional chalk box is designed, including the box body, the box cover and the sponge bottom support. There are holes at the top of the sponge bottom support for chalk insertion. The box cover is connected by a pre-teared dotted line for easy opening and classification.
The buffer design of the sponge base support reduces the damage of chalk during transportation; the design of the pre-teared dotted line makes the chalk box open in the upper part, which facilitates classification and avoids color strings and reduces resource waste.

Abstract
Description
Technical Field
[0001] The utility model provides a multifunctional chalk box, which belongs to the technical field of chalk boxes. Background Art
[0002] The information disclosed in the background technology of the present invention is only intended to increase the understanding of the overall background of the present invention, and shall not necessarily be regarded as an admission or suggestion in any form that the information constitutes the prior art already known to those skilled in the art.
[0003] Nowadays, chalks are usually packed directly in boxes. During transportation, the chalks are squeezed and collided with each other without buffering, making them fragile and easy to break, affecting their use. The chalks on the teaching podium are also scattered on the desk or in a box. It is impossible to classify chalks of different colors, and the colors of different colors of chalks will mix when they come into contact with each other, affecting the use effect and efficiency. Alternatively, you need to purchase a special chalk box for storing chalk on the podium, which is a waste of cost. Utility Model Content
[0004] The multifunctional chalk box provided by the utility model has a simple structure, can mitigate the impact during the chalk transportation process, makes the chalk difficult to break, and can classify chalks of different colors to avoid color mixing.
[0005] The utility model provides a multifunctional chalk box, comprising a box body, a box cover and a sponge base. The sponge base is installed inside the box body, and the top of the sponge base is penetrated by openings adapted to chalks. Both sides of the top and the rear side of the top of the box body are connected to the box cover through pre-torn dotted lines.
[0006] Furthermore, the box cover includes left box paper, right box paper, and rear box paper, and both sides of the top and the rear side of the top of the box body are respectively connected to the bottom ends of the left box paper, right box paper, and rear box paper through pre-torn dotted lines.
[0007] Furthermore, the bottom end surface and surrounding side walls of the sponge base are respectively bonded to the corresponding inner walls of the box body.
[0008] Furthermore, the height of the sponge base is equal to two-thirds of the height of the inner wall of the box body.
[0009] Beneficial effects of the utility model:
[0010] 1. In the utility model, the sponge base and the hole design can provide a buffer for the chalk in transportation, so that the chalk is not easy to break during transportation.
[0011] 2. In the present invention, the design of the pre-tear dotted line portion is utilized to facilitate the teacher to tear the box cover off the box body, and use the box body to organize chalks of different colors to avoid color mixing. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described below in conjunction with the accompanying drawings.
[0018] according to Figure 1-4 As shown, the multifunctional chalk box provided by the utility model comprises a box body 1, a box cover 2, and a sponge base 3. The sponge base 3 is installed inside the box body 1, and the top of the sponge base 3 is penetrated by openings 4 adapted to chalk, and both sides of the top and the rear side of the top of the box body 1 are connected to the box cover 2 through pre-torn dotted line portions 5.
[0019] Specifically, the box cover 2 includes a left box paper 201, a right box paper 202, and a rear box paper 203. Both sides of the top and the rear side of the top of the box body 1 are connected to the bottom ends of the left box paper 201, the right box paper 202, and the rear box paper 203 through the pre-torn dotted line portion 5 respectively.
[0020] Through the design of the pre-tear dotted line portion 5, the left box paper 201, the right box paper 202, and the rear box paper 203 can be torn off from the top of the box body 1 respectively, so that the chalk box becomes open at the top, which is convenient for storing and taking out chalk on the desk during teaching, and is conducive to the classification and sorting of various colors. The unused half of the chalk can also be inserted into the opening 4 of the sponge base 3 to reduce the waste of half of the chalk.
[0021] Specifically, the bottom end surface and surrounding side walls of the sponge base 3 are respectively bonded to the corresponding inner walls of the box body 1 .
[0022] The stability of the sponge base 3 is enhanced to prevent the sponge base 3 from being dragged out of the box body 1 when the chalk is taken out.
[0023] Specifically, the height of the sponge base 3 is equal to two-thirds of the height of the inner wall of the box body 1 .
[0024] When assembling the chalk into the box body 1, insert the chalk into the opening 4 on the sponge base 3, wherein the sponge base 3 can also be replaced with other materials that have a buffering effect and are easy to open holes.
[0025] Working principle of the utility model
[0026] During transportation, the design of the sponge bottom tray 3 can prevent the chalk from being easily broken during transportation. At the same time, when in use, the pre-torn dotted line portion 5 can be used to tear off the left box paper 201, the right box paper 202, and the rear box paper 203 from the top of the box body 1 respectively, so that the chalk box becomes open at the top, which is convenient for storing and taking out chalk on the desk during teaching, and is conducive to the classification and sorting of various colors. The unused half of the chalk can also be inserted into the opening 4 of the sponge bottom tray 3, reducing the waste of half of the chalk, being green and environmentally friendly, and reducing the waste of resources.
[0027] The utility model and its implementation methods are described above, wherein the components are all common standard components or components known to those skilled in the art, and the structures and principles thereof are known to those skilled in the art through technical manuals or conventional experimental methods. Such description is not restrictive, and what is shown in the accompanying drawings is only one of the implementation methods of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it, and do not deviate from the inventive purpose of the utility model, they can design a structural method and implementation method similar to the technical solution without creativity, which should all fall within the protection scope of the utility model.
