Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and in particular to a hamburger box that can be flattened into a planar structure. Background Technology

[0002] Existing hamburger boxes are usually three-dimensional, which is not convenient for folding, storage or transportation. Some hamburger boxes can be folded flat with the top and bottom lids, but the bottom of the hamburger box is unstable and easy to wobble. Therefore, a new type of hamburger box is needed to solve this problem. Utility Model Content

[0003] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a hamburger box that can be flattened into a planar structure.

[0005] To achieve the above objectives, the technical solution of this utility model is: a hamburger box that can be flattened into a planar structure, comprising a lid and a base. The lid includes a top piece and four side pieces, wherein two opposite side pieces are provided with creases, and the other two side pieces are attached to the top piece through the creases. The base includes four peripheral pieces, two bottom pieces, and two adhesive pieces. Two bottom pieces are connected to two opposite peripheral pieces, and two adhesive pieces are connected to two other opposite peripheral pieces. Two adhesive pieces are provided with creases, which divide the adhesive piece into an adhesive part and a splicing part. The adhesive part is bonded to the bottom surface of the adjacent bottom piece.

[0006] By adopting the above technical solution, the lid is a cube formed by four side pieces and a top piece. Folds on two side pieces allow the other two side pieces to be bent along fold one and adhere to the top piece, thus forming a planar structure. The bottom box is a cube formed by four peripheral pieces, two adhesive pieces, and two bottom pieces. Folds two sets of adhesive pieces together allow the bottom and adhesive pieces to bend upwards. The box walls formed by the four peripheral pieces can be folded along two opposite edges, forming a planar structure. The bottom and adhesive pieces bend upwards and are sandwiched between the four peripheral pieces. This method allows both the lid and bottom box to form planar structures, facilitating storage and transportation. Furthermore, the bottom of the box, formed by the combination of two bottom pieces and two adhesive pieces, will not separate when subjected to downward force due to interlocking, ensuring box stability.

[0007] Preferably, each of the two side pieces with the first crease is provided with an adhesive piece on both sides. The adhesive piece is bent and then bonded to the adjacent side piece. In this invention, the two side pieces with the first crease are actually located on the left and right sides of the box lid. They are bent at 90° by the adhesive piece and connected to the two side pieces without the first crease, so that the four side pieces can form the side wall of the box lid.

[0008] Preferably, there are two creases on the same side piece, both of which originate from the vertex of the top piece and extend to the bottom edge of the side piece. The two creases are inclined along the angle bisector and in opposite directions.

[0009] This invention utilizes this type of crease to achieve a planar structure for the box lid.

[0010] Preferably, one of the outermost peripheral pieces is provided with an adhesive piece two, which is bonded to the other outermost peripheral piece. In this invention, the four peripheral pieces are interconnected, forming the walls of the bottom box through bending creases. The two outermost peripheral pieces are fixed together by using the adhesive piece two.

[0011] Preferably, one of the side pieces without crease one is integrally connected to one of the peripheral pieces, and the other side piece without crease one has an extension portion with card one on both sides of the extension portion, and the peripheral pieces on both sides have card two, with card one and card two interlocking with each other. This invention allows the lid and bottom box to form an integral unit through the connection between the side pieces and the peripheral pieces. The crease at the connection between the side pieces and the peripheral pieces allows the lid and bottom box to be flipped open and closed. When closed, card one moves to card two, and by interlocking card one above card two, the lid and bottom box can remain closed.

[0012] Preferably, the two side pieces with the first crease extend downward to form a covering portion. This invention utilizes the covering portion to cover the gaps on both sides between the box lid and the bottom box; the gap on the front side is covered by the extension portion.

[0013] Preferably, the connection between the side panel and the peripheral panel is provided with a perforation. This invention utilizes the perforation to allow air to pass through the hamburger box, enabling water vapor to escape and prevent it from affecting the food.

[0014] Preferably, the two adhesive pieces are provided with snap-fit ​​grooves. This invention utilizes snap-fit ​​grooves to ensure that the two adhesive pieces interlock when assembled into the bottom, preventing them from easily spreading out downwards and thus making the bottom more stable.

[0015] Preferably, the cover has beveled edges on both sides. This invention uses beveled edges to ensure that the cover does not interfere with the closing of the lid.

[0016] Preferably, the top piece, the side pieces, the peripheral pieces, the adhesive piece, the bottom piece, the first adhesive piece, and the second adhesive piece are integrally formed, and each has a bend at its connection point. This design allows the hamburger box to...

[0017] In summary, the beneficial effects of this utility model are:

[0018] 1. The lid is a cube formed by four side pieces and a top piece. Folds on two side pieces allow the other two side pieces to be bent along fold one and attached to the top piece, thus forming a flat structure. The bottom box is a cube formed by four peripheral pieces, two adhesive pieces, and two bottom pieces. Folds two sets of adhesive pieces together allow the bottom piece and adhesive piece to bend upwards. The box walls formed by the four peripheral pieces can be folded along two opposite edges, forming a flat structure. The bottom piece and adhesive piece bend upwards and are sandwiched between the four peripheral pieces. In this way, both the lid and the bottom box can form a flat structure, which ensures the hamburger box shape after molding while also forming a flat structure, saving transportation and storage costs.

[0019] 2. After the bottom structure is formed, it has a fixed and mutually abutting structure to ensure the stability of the bottom and prevent it from falling apart.

[0034] like Figure 1-3 As shown, a hamburger box that can be flattened into a planar structure includes a lid and a base. The lid includes a top piece 1 and four side pieces 2, wherein two opposite side pieces are provided with creases 3, and the other two side pieces are attached to the top piece 1 through creases 3. The base includes four peripheral pieces 4, two bottom pieces 5, and two adhesive pieces 6. The two bottom pieces 5 are connected to two opposite peripheral pieces 4, and the two adhesive pieces 6 are connected to two other opposite peripheral pieces 4. The two adhesive pieces 6 are provided with creases 7, which divide the adhesive piece 6 into an adhesive part 17 and a splicing part 18. The adhesive part 17 is bonded to the bottom surface of the adjacent bottom piece 5.

[0035] By adopting the above technical solution, the lid is a cube formed by four side pieces 2 and a top piece 1. The creases 3 on two side pieces 2 allow the other two side pieces 2 to be bent along the creases 3 and attached to the top piece 1, so that the lid can form a planar structure. The bottom box is a cube formed by four peripheral pieces 4, two adhesive pieces 6 and two bottom pieces 5. The bottom pieces 5 and adhesive pieces 6, which are glued together by the creases 7, can be bent upwards. The box wall formed by the four peripheral pieces 4 can be folded along two opposite edges, so that the box wall forms a planar structure. The bottom pieces 5 and adhesive pieces 6 are bent upwards and sandwiched between the four peripheral pieces 4. In this way, both the lid and the bottom box can form a planar structure, which facilitates storage and transportation. At the same time, the bottom of the bottom box formed by the combination of the two bottom pieces 5 and the two adhesive pieces 6 will not separate when subjected to downward force due to mutual interlocking, so that the box body is stable.

[0036] Both sides of the two side pieces 2 with crease 3 are provided with adhesive tabs 8. After being bent, the adhesive tabs 8 are glued to the adjacent side pieces 2. The two side pieces 2 with crease 3 are actually located on the left and right sides of the box lid. They are bent 90° by the adhesive tabs 8 and connected to the two side pieces 2 without crease 3, so that the four side pieces 2 can form the side wall of the box lid.

[0037] There are two creases 3 on the same side piece 2. Both creases 3 originate from the vertex of the top piece 1 and extend to the bottom edge of the side piece 2. The two creases 3 are inclined along the angle bisector, and the inclination directions of the two creases 3 are opposite. This type of crease 3 is used to achieve the planar structure of the box lid.

[0038] One of the outermost peripheral pieces 4 is provided with an adhesive piece 2 9, which is bonded to another outermost peripheral piece 4. The four peripheral pieces 4 are connected to each other and can form the box wall of the bottom box through bending lines. The two outermost peripheral pieces 4 are fixed together by using the adhesive piece 2 9.

[0039] One side panel 2 without crease 3 is connected to one of the peripheral panels 4 as a single unit. The other side panel 2 without crease 3 has an extension 10 with card 11 on both sides. The peripheral panels 4 on both sides have card 2 12. Card 11 and card 2 12 are interlocked. The connection between the side panel 2 and the peripheral panel 4 allows the lid and the bottom box to form a single unit. The crease at the connection between the side panel 2 and the peripheral panel 4 allows the lid and the bottom box to be flipped open and closed. When closed, card 11 moves to card 2 12. By interlocking card 11 above card 2 12, the lid and the bottom box can be kept closed.

[0040] Two side panels 2 with creases 3 extend downward to form a cover 13. The cover 13 covers the gaps on both sides between the box lid and the bottom box, and the gap on the front side is covered by the extension 10.

[0041] A cutout 14 is provided at the connection between the side panel 2 and the peripheral panel 4. The cutout 14 allows the inside of the hamburger box to be ventilated, allowing water vapor to escape and avoid affecting the food.

[0042] The two adhesive pieces 6 have snap-fit ​​grooves 15. The snap-fit ​​grooves 15 make the two adhesive pieces 6 interlock when they are assembled into the bottom, preventing them from falling apart and making the bottom more stable.

[0043] The cover 13 has beveled edges 16 on both sides. The beveled edges 16 ensure that the cover 13 does not interfere with the closing of the lid.

[0044] Top piece 1, side piece 2, peripheral piece 4, adhesive piece 6, bottom piece 5, adhesive piece 1 8, and adhesive piece 2 9 are molded as a single piece, and all joints have creases. This design allows the hamburger box to...

[0045] In summary, when storing the hamburger box, firstly, along the crease 3 on the two side pieces 2, the other two side pieces 2 can be bent and attached to the top piece 1 through the crease 3, so that the lid can form a flat structure. Through the crease 7, the two sets of glued bottom pieces 5 and adhesive pieces 6 can be bent upwards, and the box wall formed by the four peripheral pieces 4 can be folded along two opposite edges, so that the box wall forms a flat structure. The bottom piece 5 and adhesive pieces 6 are bent upwards and sandwiched between the four peripheral pieces 4. At this time, the entire hamburger box can form a flat structure. At the same time, the bottom box can be folded again along the crease between the peripheral pieces, thereby reducing the horizontal size.

[0046] When unfolding the hamburger box, pull the two side pieces 2 attached to the top piece 1 outwards. The other two side pieces 2 will also be lifted up. At this time, the lid is fully unfolded. Then, pull the two opposite peripheral pieces 4 outwards so that the four peripheral pieces 4 form the box wall of the bottom box. During the unfolding process, since the bottom piece 5 and the adhesive piece 6 are glued together, the bottom piece 5 and the adhesive piece 6 will also unfold and combine together under the pull of the peripheral pieces 4 to form the bottom of the box.

[0047] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
