Description

Technical Field

[0001] This utility model relates to the field of pencil packaging box technology, and in particular to a pencil packaging box with a built-in pencil sharpening function. Background Technology

[0002] In the existing technology, pencils, as a common writing and drawing tool, have relatively simple packaging forms. The main function of traditional pencil packaging boxes is limited to storing and carrying pencils. They are usually just simple boxes that neatly place multiple pencils inside. This packaging method has certain shortcomings.

[0003] When a pencil tip becomes dull during use, traditional packaging boxes cannot provide an effective solution. Users need to find pencil sharpeners, sandpaper, and other pencil sharpening tools to sharpen the tip. However, in daily life, pencil sharpening tools may not always be carried with them. This means that users cannot sharpen the tip in time after it becomes dull, which affects the smoothness and effect of writing and cannot meet users' needs for quick and convenient pencil sharpening in different scenarios.

[0004] Therefore, designing a pencil box with a built-in tip-sharpening function to meet users' needs for tip trimming is of great practical significance. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a pencil packaging box with a built-in lead-grinding function.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pencil packaging box with a built-in lead-sharpening function includes a pull-out outer box, inside which a pull-out box assembly is provided by a pull-out mechanism, and the pencil body is placed inside the pull-out box assembly. Lead-sharpening sandpaper is fixed to the pull-out box assembly by an adhesive method.

[0008] As a further embodiment of this utility model: the pull-out box assembly includes an adhesive paper and a pull-out box body. The adhesive paper and the pull-out box body are bent and shaped between their front and rear positions, and the adhesive paper and the pull-out box body are fixed to each other by an adhesive method between their left and right positions.

[0009] As a further improvement of this utility model: the front and rear positions of the pull-out box body are both formed with box tongues by bending, and the sandpaper is glued and fixed to one of the box tongues.

[0010] As a further improvement of this utility model: both sides of the pull-out box body are provided with strip-shaped holes, and a limiting cardboard is installed in the strip-shaped holes by insertion.

[0011] As a further improvement of this utility model, the top and bottom of the pull-out box are both provided with notches.

[0012] As a further improvement of this utility model, the main body of the pull-out box unfolds into a cross-shaped structure.

[0013] As a further improvement of this utility model, the limiting cardboard is U-shaped.

[0014] Compared with the prior art, this utility model provides a pencil box with a built-in pencil sharpening function, which has the following beneficial effects:

[0015] 1. By fixing the sandpaper to the tongue of the pull-out case assembly, when the pencil tip becomes dull and affects the writing effect, the user only needs to pull the pull-out case assembly out of the outer case and use the sandpaper to rub the tip to quickly make the tip sharp again.

[0016] 2. By creating notches at the top and bottom of the pull-out box, users can easily use their fingers to grip the tongue and the main body of the pull-out box when they need to pull the pull-out box components along the outer box.

[0017] 3. The U-shaped limiting cardboard effectively supports the pencil body and prevents it from falling. Even when the pull-out box body is in the open-down position, it can ensure that the pencil body is securely stored inside the pull-out box body.

[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Example 1

[0026] A pencil box with a built-in pencil sharpening function, such as Figures 1 to 4 As shown, it includes a pull-out box 1, inside which a pull-out box assembly is provided by a pull-out method, and a pencil body 3 is placed inside the pull-out box assembly, and a sharpening sandpaper 5 is fixed on the pull-out box assembly by an adhesive method.

[0027] The outer box 1 of the pull-out box can be used to place the pull-out box assembly, which can hold the pencil body 3. When the tip of the pencil body 3 is used to a certain extent, it will become dull, which will affect the writing effect. At this time, the tip of the pencil body 3 is rubbed with the sandpaper 5 to sharpen the tip of the pencil body 3, thereby making the tip of the pencil body 3 sharp again.

[0028] The pull-out box assembly includes an adhesive paper 6 and a pull-out box body 7. The pull-out box body 7 unfolds into a cross-shaped structure. The adhesive paper 6 and the pull-out box body 7 are bent between the front and rear positions, and the adhesive paper 6 and the pull-out box body 7 are fixed to each other by adhesive. The pull-out box body 7 has a box tongue 2 formed by bending at both the front and rear positions, and the sandpaper 5 is glued and fixed to one of the box tongues 2.

[0029] After the pull-out box body 7 is transformed from a two-dimensional state to a three-dimensional state by using the adhesive paper 6, the pencil body 3 can be placed inside, and the sandpaper 5 can be glued and fixed using the box tongue 2.

[0030] The pull-out box 1 has openings 4 at both the top and bottom;

[0031] The notch 4 makes it easy to grip the tongue 2 and the main body 7 with your fingers when the pull-out box assembly needs to be pulled along the outer box 1.

[0032] Working principle: The pull-out box assembly is used to hold the pencil body 3. When the tip of the pencil body 3 becomes dull after a certain period of use, the tip of the pencil body 3 is rubbed with the sandpaper 5 fixed on the box tongue 2. The friction is used to sharpen the tip of the pencil body 3, making the tip of the pencil body 3 sharp again. After the pencil body 3 is finished using, the pull-out box assembly is pushed back into the outer box 1 of the pull-out box, so that the pencil body 3 can be stored and carried for convenience.

[0033] Example 2:

[0034] A pencil box with a built-in sharpening function, designed to protect the pencil body 3, such as... Figure 4 As shown, this embodiment makes the following additions based on embodiment 1: both sides of the pull-out box body 7 are provided with strip-shaped holes 8, and a limiting cardboard 9 is installed in the strip-shaped holes 8 by insertion. The limiting cardboard 9 is U-shaped.

[0035] When the pull-out box body 7 is pulled out from the pull-out box outer box 1, in order to prevent the pencil body 3 from falling out of the pull-out box body 7 with the opening facing down, the limiting cardboard 9 can play a supporting and protective role for the pencil body 3, ensuring that the pencil body 3 will not fall out even if the pull-out box body 7 is pulled out from the pull-out box outer box 1 with the opening facing down.

[0036] When it is necessary to remove the pencil body 3 from the pull-out box body 7, simply pull one end of the limiting cardboard 9 out of the slot 8 to remove the pencil body 3 from the pull-out box body 7 for use.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
