Description

Technical Field

[0001] The utility model belongs to the technical field of packaging boxes, and more specifically, particularly relates to a schoolbag-shaped packaging box. Background Art

[0002] Paper packaging boxes are widely used in food, electronic products, cosmetics, pharmaceutical products, etc. due to their convenience, environmental protection, and low cost. Some paper packaging boxes are formed by cutting raw materials into specific shapes and then folding them into box shapes that can store products. Currently, a large number of packaging boxes are folded into rectangular boxes, and the packaging is completed by inserting a cover plate into the gap between the side ears and the front enclosure panel. To open the packaging box, fingers need to be inserted into the gap to buckle the front end of the cover plate, resulting in deformation of the packaging box. In subsequent use, the gap will expand, and the internal items are not well protected during packaging.

[0003] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a schoolbag-shaped packaging box is provided with the expectation of achieving a more practical value. Summary of the Utility Model

[0004] To solve the above technical problems, the utility model provides a schoolbag-shaped packaging box to solve the problems that ordinary rectangular packaging boxes are easily deformed when opened, the gap expands in subsequent use, and the internal items are not well protected during packaging.

[0005] The purpose and effect of a schoolbag-shaped packaging box of the utility model are achieved by the following specific technical means:

[0006] A schoolbag-shaped packaging box includes a front enclosure panel, a rear enclosure panel, and two side panels. The front enclosure panel is connected to the rear enclosure panel through one of the side panels, and the other side of the rear enclosure panel is connected to the other side panel so that the whole can enclose into a rectangle. A cover plate is provided at the top of the rear enclosure panel. The cover plate is arc-shaped and covers the top of the rectangular box to form a schoolbag shape with the front side. An insertion ear is provided at the front end of the cover plate, and a jack corresponding to the insertion ear is provided on the rear enclosure panel.

[0007] Further, a lining board is provided at the top of the front enclosure panel, and a lifting tongue is provided on the lining board. A lifting opening corresponding to the lifting tongue is provided on the cover plate.

[0008] Further, a stacking plate that is mirror-symmetrical to the lifting tongue is provided at the top of the lifting tongue.

[0009] Further, a connecting plate is provided on one side of the rear enclosure panel.

[0010] Further, connecting ears are provided at both ends of the side panel.

[0011] Further, a bevel edge is provided on one side of the top of the side panel close to the front enclosure panel, and a transition plate matching the bevel edge is connected between the lining board and the front enclosure panel.

[0012] Further, a bottom sealing plate is provided at the bottom of the front bulkhead, and an insertion plate is provided at the bottom of the rear bulkhead.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] Through the design of the overly long cover plate, the cover plate can cover the top of the rectangular box and at the same time fit on the outer side of the front bulkhead to form a schoolbag-shaped box body. The insertion lugs provided at the front end of the cover plate are inserted into the insertion holes on the front bulkhead to complete the box-shaped packaging. The switch box is more convenient. At the same time, opening the box only requires pushing up the cover plate on the outer side of the front bulkhead, which does not affect the precision of the packaging during secondary use and is not easily deformed.

[0023] Embodiment:

[0024] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0025] The present utility model provides a schoolbag-shaped packaging box, which includes a front panel 3, a rear panel 1, and two side panels 2. The front panel 3 is connected to the rear panel 1 through one of the side panels 2, and the other side of the rear panel 1 is connected to the other side panel 2 so that the whole can be enclosed into a rectangle. A connecting plate 8 is provided on one side of the rear panel 1, and the side panels 2 at the edge of the connecting plate 8 are adhesively bonded to each other to form a rectangular box.

[0026] A cover plate 5 is provided at the top of the rear panel 1. The cover plate 5 is arc-shaped and covers the top of the rectangular box to form a schoolbag shape with the front side. The rear side of the cover plate 5 covers and seals the top of the rectangular box, and its front side is buckled on the outside of the front panel 1. An insertion ear 501 is provided at the front end of the cover plate 5, and a jack 12 corresponding to the insertion ear 501 is opened on the rear panel 1. When the insertion ear 501 is inserted into the jack 12, the packaging of the box body is completed. In this embodiment, a pair of insertion ears 501 are provided to increase the connection strength and optimize the symmetrical appearance.

[0027] On one side of the top of the side panel 2 close to the front panel 3, there is an inclined edge 201. A transition plate 901 matching the inclined edge 201 is connected between the inner lining plate 9 and the front panel 3. When folding, the side edge of the transition plate 901 is aligned with the inclined edge 201 so that a tabletop is formed at the top of the box surface. When the cover plate 5 is closed, the cover plate 5 fits on the tabletop, and a part of its side edge fits on the inclined edge 201, increasing the sealing performance.

[0028] Among them, an inner lining plate 9 is provided at the top of the front panel 3, and a lifting tongue 10 is provided on the inner lining plate 9. The lifting tongue 10 is in the shape of rabbit ears. A lifting opening 502 corresponding to the lifting tongue 10 is opened on the cover plate 5. When the cover plate 5 is closed, the lifting tongue 10 extends out from the lifting opening 502 for the user to lift and carry. A stacking plate 11 mirror-symmetrical to the lifting tongue 10 is provided at the top of the lifting tongue 10. During the folding process, the stacking plate 11 coincides with the lifting tongue 10, increasing the thickness and structural strength of the lifting tongue 10 and avoiding the breakage of the lifting tongue 10 during the hand-carrying process.

[0029] The rest of this packaging box is similar to the prior art. Connecting ears 4 are provided at both ends of the side plate 2 to increase the closing strength during the folding and packaging process. A bottom sealing plate 6 is provided at the bottom of the front enclosure plate 3 of the side plate 2, and an insertion plate 7 is provided at the bottom of the rear enclosure plate 1 to seal the bottom of the box shape.

[0030] The embodiments of the present invention are given for purposes of illustration and description, and are not exhaustive or limit the present invention to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are chosen and described in order to best explain the principles of the present invention and its practical application, and to enable those of ordinary skill in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.
