Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and more specifically to a backpack-style packaging box. Background Technology

[0002] Currently, packaging boxes with handles typically come in two types: integrated handles and detachable handles. Integrated handles are essentially external, formed by folding. Because the handle is always exposed on the box's surface, the product's appearance is unsightly, and the handle is easily damaged during use or transportation. Detached handles, on the other hand, require separate installation. Since the handle component is independent, it's prone to loss and needs to be reinstalled on the box, increasing installation steps, reducing efficiency, and making it less convenient to use. The handle's sturdiness may also be compromised.

[0003] In addition, as people's consumption level increases, the requirements for product packaging boxes are also gradually increasing, especially for children's products and snacks. If the packaging can be interesting to children, it will have a positive effect on the sales volume of the products. Therefore, many children's products and snacks use more fancy and exaggerated colors or complicated structures to attract children's attention. However, with increasing market competition and a wide variety of packaging, it is no longer possible to stand out from the crowd by relying solely on colors or special patterns and shapes. Utility Model Content

[0004] The purpose of this utility model is to provide a backpack-style packaging box that is both fun and practical.

[0005] To achieve the above objectives, this utility model provides a backpack-style packaging box, including a box body, a handle, and two shoulder straps, with the box body and the handle located on the same piece of material; The enclosure includes a front panel, a back panel, two side panels, a bottom panel, and a cover. The rear end of the cover is connected to the back panel by a fold line. The cover covers the top of the enclosure and has a first through hole. The handle includes a handle part and a connecting part. The connecting part is connected to the upper end of one side panel of the box body by a fold line. The handle part passes through the first through hole of the cover plate from bottom to top and protrudes from the cover plate. The back panel of the case has a connection hole at each of the four corners. The upper ends of the two shoulder straps are fixed in the two connection holes at the top of the back panel, and the lower ends of the two shoulder straps are fixed in the two connection holes at the bottom of the back panel.

[0006] Furthermore, the handle has a double-layer structure, including two symmetrical handle pieces, each with a handle portion. Each handle piece has a base piece below its handle portion. The two handle pieces are folded together so that the two handle portions overlap and pass through the first through hole. The two base pieces open to the sides perpendicular to the handle portions, and the connecting part connects one of the base pieces to one of the side panels.

[0007] Furthermore, the two side panels include a first side panel and a second side panel. The first side panel, the front panel, the second side panel, and the back panel are connected in sequence by fold lines. The handle is connected to the upper end of the second side panel. The upper end of the first side panel is connected by fold lines to a limiting piece for preventing the handle from coming off the cover plate. The limiting piece is located between the cover plate and the bottom piece of the handle.

[0008] Furthermore, the width of the upper part of both side panels gradually decreases upwards.

[0009] Furthermore, the front end of the cover plate is fixed to the front panel.

[0010] Furthermore, the bottom plate includes a first bottom plate, a second bottom plate, and two opposite bottom side plates. The front ends of the first bottom plate and the second bottom plate are respectively provided with corresponding protrusions and grooves. The two bottom side plates are folded from both sides under the second bottom plate. The first bottom plate inserts the protrusions into the grooves from under the two bottom side plates to fix it and form the bottom plate.

[0011] Furthermore, the front panel includes an upper front panel and a lower front panel connected by a fold line, and the lower parts of the first side panel and the second side panel are respectively connected to the two sides of the lower front panel. The upper part of the first side panel and the second side panel is a right trapezoid with the hypotenuse facing the upper front panel.

[0012] Furthermore, a second through hole is formed on the limiting piece, which coincides with the first through hole on the top projection plane. The handle passes through the second through hole and the first through hole from bottom to top and protrudes from the box cover plate.

[0013] Furthermore, the upper part of the first side panel and the second side panel are folded inward to form an isosceles trapezoid.

[0014] Furthermore, the limiting piece is a protrusion that protrudes upward from the center of the first side panel. When the cover is closed, the limiting piece overlaps the bottom piece of the handle.

[0015] With the above solution, the body and handle of the backpack-style packaging box of this utility model are located on a unified cut body. The complete backpack-style packaging box can be assembled by folding and gluing without the need for subsequent assembly work, saving raw materials and production costs. In addition, this backpack-style packaging box is equipped with connecting holes and shoulder straps.

[0023] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0024] See Figures 1 to 5 The first embodiment of this utility model provides a backpack-style packaging box, including a box body 1, a handle 2, and two shoulder straps 3, with the box body 1 and the handle 2 located on the same body.

[0025] The case 1 includes a front panel 11, a back panel 12, two side panels, a bottom plate, and a cover plate 16. The rear end of the cover plate 16 is connected to the back panel 12 by a fold line. The cover plate 16 covers the top of the case 1 and has a first through hole 161 at the top of the case 1. The back panel 12 of the case 1 has a connecting hole 121 at each of its four corners. The upper ends of the two shoulder straps 3 are fixed in the two connecting holes 121 at the top of the back panel 12, and the lower ends of the two shoulder straps 3 are fixed in the two connecting holes 121 at the bottom of the back panel 12.

[0026] The shoulder strap 3 can be made of soft nylon rope, etc., with the two ends of the rope passing through the two corresponding connecting holes 121 and fixed to the inner wall of the back panel 12 of the box body 1 to form the shoulder strap 3 of a backpack.

[0027] To facilitate differentiation, the two side panels are designated as the first side panel 13 and the second side panel 14. The first side panel 13, the front panel 11, the second side panel 14, and the back panel 12 are connected sequentially by fold lines. A connecting piece is also protruding from the end of the back panel 12. When the first side panel 13, the front panel 11, the second side panel 14, and the back panel 12 are arranged to form the side of the box 1, the connecting piece is attached to the first side panel 13 to form a fixed structure.

[0028] The cover plate 16 folds forward from the back panel 12 to cover the box body 1. After the middle section of the cover plate 16 covers the top of the box body 1, its front end is fixed to the front panel 11 of the box body 1. This utility model can make the upper part of the two side panels into a shape that gradually narrows upwards, thereby making the part of the cover plate 16 at the top of the box body 1 shorter, reducing the overall area of ​​the cover plate 16 and saving raw materials. In this embodiment, two fold lines are provided on the upper sides of the first side panel 13 and the second side panel 14. After the box body 1 is formed, it can be folded inward along the fold lines, so that the upper part of the first side panel 13 and the second side panel 14 forms an isosceles trapezoid, making the opening at the top of the box body 1 smaller, and the required area of ​​the cover plate 16 is also smaller.

[0029] The bottom plate includes a first bottom plate 151, a second bottom plate 152, and two opposite bottom side plates 153. The front ends of the first bottom plate 151 and the second bottom plate 152 are respectively provided with corresponding protruding buckles 1511 and buckle grooves 1521. The two bottom side plates 153 are folded from both sides below the second bottom plate 152. The first bottom plate 151 inserts the protruding buckles 1511 into the buckle grooves 1521 from below the two bottom side plates 153 to fix it and form the bottom plate. In this embodiment, the first bottom plate 151 is connected to the lower end of the back panel 12 by a fold line, the second bottom plate 152 is connected to the lower end of the front panel 11 by a fold line, and the two bottom side plates 153 are connected to the lower ends of the first side panel 13 and the second side panel 14 by fold lines, respectively.

[0030] The handle 2 includes a handle portion 211 and a connecting portion 213. The connecting portion 213 is connected to the upper end of one side panel of the box body 1 by a fold line, so that the handle 2 and the box body 1 are located on the same body. The handle portion 211 passes through the first through hole 161 of the cover plate 16 from bottom to top and protrudes from the cover plate 16.

[0031] Specifically, in this embodiment, the handle 2 has a double-layer structure, including two symmetrical handle pieces 21, each with a handle portion 211. Each handle piece 21 has a base piece 212 below the handle portion 211. The two handle pieces 21 are folded together so that the two handle portions 211 overlap and pass through the first through hole 161. The two base pieces 212 open to both sides perpendicular to the handle portion 211. The connecting part 213 connects one of the base pieces 212 to one of the side panels (in this embodiment, the connecting part 213 of the handle 2 is connected between the base piece 212 and the upper end of the second side panel 14).

[0032] Preferably, in this embodiment, the upper end of the first side panel 13 is connected by a fold line to a limiting piece 131 for preventing the handle 2 from being pulled upward out of the cover plate 16. The limiting piece 131 is a protrusion protruding upward from the middle of the first side panel 13. When the cover plate 16 is closed, the limiting piece 131 is located between the cover plate 16 and the bottom piece 212 of the handle 2 and overlaps the bottom piece 212 of the handle 2, so as to prevent the handle 2 from deforming and detaching from the box 1 due to being pulled.

[0033] In the backpack-style packaging box of the above embodiment, the box body 1 and the handle 2 are located on a unified cut body. The complete backpack-style packaging box can be assembled by folding and gluing without the need for subsequent assembly work, saving raw materials and production costs. In addition, this backpack-style packaging box is equipped with a connecting hole 121 and a shoulder strap 3. In addition to being carried by hand, it can also be carried on the back in the form of a backpack, which is interesting and can attract consumers. It can also be reused, making it more practical.

[0034] See Figure 6 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the front panel 11 of the second embodiment includes an upper front panel 111 and a lower front panel 112 connected by a folded line. A second bottom panel 152 is connected to the lower end of the lower front panel 112 by a folded line. The lower parts of the first side panel 13 and the second side panel 14 are respectively connected to the two sides of the lower front panel 112. The upper parts of the first side panel 13 and the second side panel 14 are right-angled trapezoids with their hypotenuses facing the upper front panel 111. The limiting piece 131 of the second embodiment has a second through hole 1311 formed on it, which coincides with the first through hole 161 in a top-view projection. The handle 211 passes through the second through hole 1311 and the first through hole 161 sequentially from bottom to top and protrudes from the cover plate 16 of the box body 1.

[0035] The above is merely one embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
