[0020] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0021] Embodiment 1

[0022] Reference Figure 1-Figure 5 , a paper box that can be pulled open in both directions, includes a paper box shell 1, a box bottom 2 is adhered to the bottom end of the paper box shell 1, a pull-out support plate 3 is slidably embedded in the top of the box bottom 2 on the inner side of the paper box shell 1, and an inner box 4 is slidably embedded in the top of the pull-out support plate 3 on the inner side of the paper box shell 1. A left sliding limit groove 5 is penetrated at the midline position of the box bottom 2, and a circular cardboard 6 is adhered to the bottom end of one side of the pull-out support plate 3. The pull-out support plate 3 is slidably embedded in the inner side of the left sliding limit groove 5 through the circular cardboard 6. In order to achieve the limit of pulling out on the left side, the diameter of the circular cardboard 6 is smaller than the inner width of the left sliding limit groove 5, and two right sliding guide grooves 7 are penetrated at the bottom ends of the box bottom 2 and the pull-out support plate 3. Two right sliding limit grooves 8 are penetrated on one side of the bottom end of the box bottom 2 and the pull-out support plate 3. In order to achieve the limit when pulling out on the right side, two card-embedded cardboards 9 are adhered to the bottom end of the inner box 4, and the middle of the two card-embedded cardboards 9 There is a horizontal cardboard 10 glued to it. In order to increase the supporting strength of the two embedded cardboards 9, two limiting paper blocks 11 are glued to the bottom end of one side of the inner box 4. The two limiting paper blocks 11 and the two right sliding limiting grooves 8 are respectively located on two parallel horizontal lines. The height of the two limiting paper blocks 11 relative to the bottom end of the outer side of the inner box 4 is less than the height of the two embedded cardboards 9 relative to the bottom end of the outer side of the inner box 4. In order to prevent damage to the limiting paper blocks 11 during movement, an equal-height cardboard 12 is glued to the bottom end of one side of the inner box 4, so that the two sides are symmetrical and more beautiful. A left-pull limiting cardboard 13 is glued to the bottom end of one side of the pull-out support plate 3. In order to increase the friction force on the inner box 4 when the left side is pulled out, a number of resistance-increasing cardboards 14 are glued to both sides of the top of the pull-out support plate 3. A closed cardboard 15 is wrapped and glued on the lower side of one side of the box bottom 2 to cover the groove opened at the bottom end of the box bottom 2 to avoid affecting the appearance.

[0023] Working principle: First, the operator sets up the production of the outer shell structure as a separate production line, which includes: opening a left sliding limit groove 5, a circular cardboard 6 and a right sliding limit groove 8 at the marked position on the bottom surface of the box bottom 2, and then wrapping and gluing the closed cardboard 15 to the outer side of the bottom of the box bottom 2, and finally gluing the box bottom 2 with the closed cardboard 15 to the inner bottom end of the paper box shell 1, thus completing the production of the support and limit structure of the packaging box, and then opening a left sliding limit groove 5, a circular cardboard 6 and a right sliding limit groove 8 at the marked position at the bottom of the pull-out support plate 3, and then gluing the circular cardboard 6 to One side of the bottom of the pull-out support plate 3, then glue the left-pull limiting cardboard 13 to the other side of the bottom of the pull-out support plate 3, and finally glue a number of resistance-increasing cardboards 14 to both sides of the top of the pull-out support plate 3, so that the production of the left-side pull-out structure is completed. The last production line first needs to glue two cardboards 9 at the bottom of the inner box 4, and then glue a transverse cardboard 10 between the two cardboards 9, and then glue two limiting paper blocks 11 to one side of the bottom of the inner box 4, and then glue the equal-height cardboard 12 to the other side of the bottom of the inner box 4, so that the production of the right-side pull-out structure is completed, thereby completing the production of all components;

[0024] After that, it is only necessary to lift up one end of the assembled pull-out support plate 3, and then slide and insert it from the left side of the assembled paper box shell 1, and then slide and insert the assembled inner box 4 from the right side of the paper box shell 1, and place it on the top of the pull-out support plate 3, so that the assembly of the entire packaging box can be completed. After the assembly is completed, pull the pull-out support plate 3 to the left, and the inner box 4 at the top of the pull-out support plate 3 will also move to the left due to the increased resistance of the resistance increasing cardboard 14, until the circular cardboard 6 at the bottom end of the pull-out support plate 3 slides to the end of the left sliding limit groove 5, then the left side of the packaging box can be pulled out, and by pulling the inner box to the right When the box 4 is pulled out, the inner box 4 will slide on the top of the pull-out support plate 3 until the horizontal cardboard 10 slides out of the top of the box bottom 2 and loses its supporting function. At that time, the two embedded cardboards 9 will fall into the two right sliding guide grooves 7. At that time, the gap between the bottom end of the box bottom 2 and the pull-out support plate 3 will be reduced, and the two limiting paper blocks 11 will contact the top of the pull-out support plate 3. As the displacement continues, the two pull-out support plates 3 will fall into the right sliding limiting groove 8. At that time, the right side pulling is completed. When restoring, you only need to push the inner box 4 upwards to let the pull-out support plate 3 break away from the restriction of the right sliding limiting groove 8, and then you can push the inner box 4 back, and the products can be stored inside the inner box 4.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
