Description

Technical Field

[0001] This utility model relates to the field of folding cardboard box technology, specifically an integrated cardboard box. Background Technology

[0002] Cardboard boxes are the most widely used packaging products. Depending on the materials used, there are corrugated cardboard boxes, single-layer cardboard boxes, etc., and they come in various sizes and models. Three-layer and five-layer cardboard boxes are commonly used, while seven-layer boxes are less common. Each layer consists of linerboard, corrugated paper, core paper, and facing paper. Linerboard and facing paper can be made of kraft paper or corrugated cardboard, while the core paper is made of corrugated paper. The color and feel of each type of paper differ, and the paper produced by different manufacturers also varies in color and feel. They are typically used as wrapping materials for goods or as the outer protective layer for items.

[0003] However, in practical use, the existing technology is not convenient for recycling cardboard boxes. When the products inside the box are used up, it is not possible to quickly restore the cardboard box to a paper structure that is easy to store, resulting in low recycling efficiency. Utility Model Content

[0004] The purpose of this invention is to provide an integrated cardboard box to solve the problem that the cardboard box cannot be quickly restored to a paper sheet structure that is easy to store, resulting in low recycling efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an integrated cardboard box, comprising a bottom plate, a first side plate, two second side plates, and a third side plate, wherein the bottom plate, the first side plate, and the two second side plates form a frame structure with a top opening. Folding plates are respectively provided between the third side plate and the two second side plates, and between the first side plate and the two second side plates. A first positioning notch is provided at each end of the folding plate away from the first side plate, the second side plate, and the third side plate. A first positioning strip is provided at each end of the two second side plates away from the bottom plate, and a positioning plate is provided at the end of the first positioning strip away from the second side plate. The width of the first positioning strip is adapted to the width of the first positioning notch. A second positioning strip is provided at the end of the positioning plate away from the second side plate, and a second positioning notch is provided at each end of the folding plate corresponding to the position of the second positioning strip.

[0006] Preferably, a first fold line is provided between the base plate and the first side plate to fold the first side plate toward the base plate; a second fold line is provided between the base plate and the second side plate to fold the second side plate toward the base plate; a third fold line is provided between the base plate and the third side plate to fold the third side plate toward the base plate; a fourth fold line is provided between the folded plate and the first, second, and third side plates to fold the folded plate toward the base plate; and a fifth fold line is provided in the middle of the folded plate, which coincides with the diagonal of the two adjacent fourth fold lines to fold the folded plate in the center, so that the folded plate is folded in the center, ultimately forming a frame structure with a top opening between the first, second, and third side plates and the base plate.

[0007] Preferably, the length of the second positioning notch at one end of the folding plate corresponding to the second side plate is less than the length of the second positioning notch at the end of the folding plate away from the second side plate, and the width of the second positioning notch is adapted to the width of the second positioning strip, so that the second positioning strip folds with the positioning plate and is inserted into the inner wall of the second positioning notch at one end of the folding plate away from the second side plate.

[0008] Preferably, the third side plate has a cover plate at one end away from the bottom plate, and the cover plate has cover plate side plates at each of the three ends away from the third side plate. A sixth fold line is provided between the cover plate and the cover plate side plates, and between the cover plate and the third side plate, so that the cover plate side plates fold towards the cover plate, and the cover plate cooperates with the cover plate side plates to provide a cover for the frame structure formed between the first side plate, the second side plate, the third side plate and the bottom plate.

[0009] Preferably, a seventh fold line is provided between the first positioning strip and the second side plate and the positioning plate, so that the positioning plate folds toward the second side plate and is arranged parallel to the second side plate. An eighth fold line is provided between the second positioning strip and the positioning plate and in the middle of the second positioning strip, so that the second positioning strip folds toward the positioning plate and then folds itself again.

[0010] Preferably, cutting lines are provided between the fifth folding line and the cover plate side plate, and between the second positioning strip and the positioning plate, so that the separation of the cover plate side plate and the folding plate does not affect the folding of the cover plate side plate and the folding plate, and does not affect the folding between the second positioning strip and the positioning plate.

[0011] Preferably, the top of the base plate is provided with a waterproof bearing frame, and the waterproof bearing frame is filled with water-absorbing material to prevent water from accumulating inside the frame structure formed between the first side plate, the second side plate, and the third side plate and the base plate.

[0012] Preferably, the integrated cardboard box is integrally molded.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model only requires the second positioning strip to be pulled out from the inner wall of the second positioning notch so that the folding plate no longer obstructs the reverse folding of the positioning plate. At this time, the positioning plate is folded in reverse, and the first positioning strip is disengaged from the first positioning notch. At this time, the entire carton can be easily unfolded without damaging the folded parts. It is also convenient to recycle. It can also be folded arbitrarily according to recycling needs through multiple folding lines, thereby achieving the purpose of improving recycling efficiency.

[0015] 2. This utility model also includes a first positioning notch, a first positioning strip, a second positioning strip, and a second positioning notch. When the first positioning strip is located on the inner wall of the first positioning notch, the folding plate cannot be folded in reverse because the first positioning strip is stuck on the inner wall of the first positioning notch. This prevents deformation of the frame structure formed between the first side plate, the second side plate, the third side plate, and the bottom plate. When only the first positioning strip is used in conjunction with the first positioning notch, when an external force is applied to the first side plate, the second side plate, and the third side plate and pulled outward, the folding plate will cause the positioning plate to fold in reverse and the first positioning strip to disengage from the first positioning notch. At this time, the second positioning strip passes through one second positioning notch and inserts into the inner wall of the other second positioning notch. This causes the second positioning strip to be squeezed between one end of the folding plate and the second side plate, making it difficult for it to disengage from the second positioning notch. In other words, the positioning plate is not easy to move relative to the folding plate. This makes it difficult for the positioning plate to fold in reverse and cause deformation of the frame structure formed between the first side plate, the second side plate, the third side plate, and the bottom plate when an external force is applied to the first side plate, the second side plate, and the third side plate and pulled outward.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-8 This utility model provides a technical solution: an integrated cardboard box, including a bottom plate 1, a first side plate 2, two second side plates 3, and a third side plate 4. The bottom plate 1, the first side plate 2, and the two second side plates 3 form a frame structure with a top opening. Folding plates 6 are respectively provided between the third side plate 4 and the two second side plates 3, and between the first side plate 2 and the two second side plates 3. The two ends of the folding plates 6 away from the first side plate 2, the second side plate 3, and the third side plate 4 are respectively provided with first positioning notches 7. The two ends of the two second side plates 3 away from the bottom plate 1 are respectively provided with first positioning strips 8, and the ends of the first positioning strips 8 away from the second side plates 3 are provided with positioning plates 9. The width of the first positioning strip 8 is equal to the width of the first positioning strip 9. The width of the notch 7 is adapted to the position. The end of the positioning plate 9 away from the second side plate 3 is provided with a second positioning strip 10. The two ends of the folding plate 6 corresponding to the position of the second positioning strip 10 are respectively provided with second positioning notches 11. The length of the second positioning notch 11 at the end of the folding plate 6 corresponding to the second side plate 3 is less than the length of the second positioning notch 11 at the end of the folding plate 6 away from the second side plate 3. The width of the second positioning notch 11 is adapted to the width of the second positioning strip 10, so that the second positioning strip 10 and the positioning plate 9 are folded and inserted into the inner wall of the second positioning notch 11 at the end of the folding plate 6 away from the second side plate 3. The integrated carton is integrally formed.

[0027] In use, the above structure, by setting the first positioning notch 7, the first positioning strip 8, the second positioning strip 10, and the second positioning notch 11, ensures that when the first positioning strip 8 is stuck in the inner wall of the first positioning notch 7, the folding plate 6 cannot be folded in reverse. The second positioning strip 10, passing through one second positioning notch 11 and inserting into the inner wall of the other, is pressed between one end of the folding plate 6 and the second side plate 3, making it difficult for it to detach from the second positioning notch 11. This means the positioning plate 9 is less likely to move relative to the folding plate 6, thus preventing external forces from acting on the first side plate 2, the second side plate 3, and the third side plate 4. When pulled outward, the positioning plate 9 is not easily folded in reverse, which would cause the first side plate 2, the second side plate 3, and the third side plate 4 to deform the frame structure with the bottom plate 1. By pulling the second positioning strip 10 out from the inner wall of the second positioning notch 11, the folding plate 6 no longer obstructs the reverse folding of the positioning plate 9. At this time, the positioning plate 9 is folded in reverse, and the first positioning strip 8 is separated from the first positioning notch 7. At this time, the entire carton can be easily unfolded without damaging the folded parts. It is also convenient to recycle. It can also be folded arbitrarily according to recycling needs through multiple folding lines, thereby achieving the purpose of improving recycling efficiency.

[0028] A first fold line 12 is provided between the base plate 1 and the first side plate 2 to fold the first side plate 2 toward the base plate 1. A second fold line 13 is provided between the base plate 1 and the second side plate 3 to fold the second side plate 3 toward the base plate 1. A third fold line 14 is provided between the base plate 1 and the third side plate 4 to fold the third side plate 4 toward the base plate 1. A fourth fold line 15 is provided between the folding plate 6 and the first side plate 2, the second side plate 3, and the third side plate 4 to fold the folding plate 6 toward the base plate 1. A fifth fold line 16 is provided in the middle of the folding plate 6, which coincides with the diagonal of the two adjacent fourth fold lines 15 to fold the folding plate 6 in the center. Finally, the first side plate 2, the second side plate 3, and the third side plate 4 form a top with the base plate 1. The open frame structure has a seventh folding line 21 between the first positioning strip 8 and the second side plate 3 and positioning plate 9, so that the positioning plate 9 folds towards the second side plate 3 and is arranged parallel to the second side plate 3. An eighth folding line 22 is provided between the second positioning strip 10 and the positioning plate 9 and in the middle of the second positioning strip 10, so that the second positioning strip 10 folds towards the positioning plate 9 and folds itself again. A cutting line 17 is provided between the fifth folding line 16 and the cover plate side plate 18 and between the second positioning strip 10 and the positioning plate 9, so that the separation of the cover plate side plate 18 and the folding plate 6 does not affect the folding of the cover plate side plate 18 and the folding plate 6, and does not affect the folding between the second positioning strip 10 and the positioning plate 9.

[0029] In use, the above structure is constructed by first folding the first side plate 2, the two second side plates 3, and the third side plate 4 90° toward the bottom plate 1 along the first fold line 12, the second fold line 13, and the third fold line 14, respectively. At the same time, the folding plate 6 is folded along the fifth fold line 16, and both ends of the folding plate 6 are folded toward the bottom plate 1 along the fourth fold line 15, until a frame structure with a top opening is formed between the first side plate 2, the second side plate 3, and the third side plate 4 and the bottom plate 1. Then, the first positioning strip 8 is folded along the seventh fold line 21 between the first positioning strip 8 and the second side plate 3, so that the first positioning strip 8 is folded into the inner wall of the first positioning notch 7. The positioning plate 9 is folded along the seventh fold line 21 between the positioning plate 9 and the first positioning strip 8. At the same time, the second positioning strip 10 is folded and inserted through one second positioning notch 11 and into another second positioning notch 11, thus completing the folding of the entire carton.

[0030] A cover plate 5 is provided at the end of the third side plate 4 away from the bottom plate 1, and cover plate side plates 18 are provided at each of the three ends of the cover plate 5 away from the third side plate 4. A sixth fold line 19 is provided between the cover plate 5 and the cover plate side plate 18, and between the cover plate 5 and the third side plate 4, so that the cover plate side plate 18 folds towards the cover plate 5. The cover plate 5, together with the cover plate side plate 18, provides a cover for the frame structure formed between the first side plate 2, the second side plate 3, and the third side plate 4 and the bottom plate 1. By folding the cover plate 5 and the cover plate side plate 18 along the sixth fold line 19, the cover plate 5 covers the top of the frame structure formed between the first side plate 2, the second side plate 3, and the third side plate 4 and the bottom plate 1, and protects the items located inside the frame structure between the first side plate 2, the second side plate 3, and the third side plate 4 and the bottom plate 1.

[0031] The top of the base plate 1 is provided with a waterproof support frame 20, and the waterproof support frame 20 is filled with water-absorbing material to prevent water from being trapped inside the frame structure formed between the first side plate 2, the second side plate 3 and the third side plate 4 and the base plate 1. By setting up the waterproof support frame 20, when water is trapped inside the frame structure, the water will be absorbed by the water-absorbing material inside the waterproof support frame 20. At the same time, the waterproof support frame 20 also elevates the items to prevent them from being soaked in water.

[0032] Working principle: In use, this utility model first folds the first side plate 2, the two second side plates 3, and the third side plate 4 90° towards the base plate 1 along the first fold line 12, the second fold line 13, and the third fold line 14, respectively. At the same time, the folding plate 6 is folded along the fifth fold line 16, and both ends of the folding plate 6 are folded towards the base plate 1 along the fourth fold line 15, until a frame structure with a top opening is formed between the first side plate 2, the second side plate 3, and the third side plate 4 and the base plate 1. At this time, the second positioning notch 11 at the end of the folding plate 6 away from the second side plate 3 is close to the base plate 1, and the first positioning notch 7 is set vertically upward. The first positioning strip 8 is folded along the seventh fold line 21 between the first positioning strip 8 and the second side plate 3, so that the first positioning strip 8 is folded into the inner wall of the first positioning notch 7. The seventh fold line 21 between the positioning plate 9 and the first positioning strip 8 is folded. Fold the positioning plate 9 along the fold line 21, so that the positioning plate 9 is finally set parallel to the second side plate 3. At the same time, fold the second positioning strip 10 and the positioning plate 9 along the eighth fold line 22, so that the second positioning strip 10 can pass through the second positioning notch 11 at the end of the folding plate 6 away from the second side plate 3. Fold the second positioning strip 10 again along the eighth fold line 22 in the middle of the second positioning strip 10, so that the second positioning strip 10 is inserted into the second positioning notch 11 at the corresponding end of the second side plate 3 of the folding plate 6, thus completing the folding of the entire carton. Finally, the cover plate 5 and the cover plate side plate 18 are folded along the sixth fold line 19 respectively, so that the cover plate 5 covers the top of the frame structure formed between the first side plate 2, the second side plate 3, and the third side plate 4 and the bottom plate 1, and protects the items inside the frame structure between the first side plate 2, the second side plate 3, and the third side plate 4 and the bottom plate 1.

[0033] By setting a first positioning notch 7, a first positioning strip 8, a second positioning strip 10, and a second positioning notch 11, when the first positioning strip 8 is located on the inner wall of the first positioning notch 7, the folding plate 6 cannot be folded in reverse because the first positioning strip 8 is stuck on the inner wall of the first positioning notch 7. This prevents the deformation of the frame structure formed between the first side plate 2, the second side plate 3, and the third side plate 4 and the base plate 1. When only the first positioning strip 8 is used in conjunction with the first positioning notch 7, when an external force is applied to the first side plate 2, the second side plate 3, and the third side plate 4 and they are pulled outward, the folding plate 6 will cause the positioning plate 9 to fold in reverse. Folding and disengaging the first positioning strip 8 from the first positioning notch 7, the second positioning strip 10 passes through one second positioning notch 11 and inserts into the inner wall of the other second positioning notch 11. This causes the second positioning strip 10 to be squeezed between one end of the folding plate 6 and the second side plate 3, making it difficult to disengage from the second positioning notch 11. In other words, the positioning plate 9 is not easy to move relative to the folding plate 6. This makes it difficult for the positioning plate 9 to fold in the opposite direction and cause the first side plate 2, the second side plate 3 and the third side plate 4 to form a frame-like structural deformation between the first side plate 2, the second side plate 3 and the third side plate 4 and the bottom plate 1 when an external force is applied to pull the first side plate 2, the second side plate 3 and the third side plate 4 outward.

[0034] When recycling is required, simply pull the second positioning strip 10 out from the inner wall of the second positioning notch 11 so that the folding plate 6 no longer obstructs the reverse folding of the positioning plate 9. At this time, the positioning plate 9 is folded in reverse, and the first positioning strip 8 is disengaged from the first positioning notch 7. The entire carton can then be easily unfolded without damaging the folded parts, and it is also convenient to recycle. It can also be folded arbitrarily according to recycling needs through multiple folding lines, thereby achieving the goal of improving recycling efficiency.

[0035] By incorporating a waterproof support frame 20, the items are elevated within the frame. The frame 20 is filled with absorbent material, including hydrophilic fiber paper, polyacrylonitrile, polyacrylic acid superabsorbent polymer, polyethylene, and all-wood pulp kraft paper. When water is trapped within the frame structure, the moisture is absorbed by the absorbent material within the waterproof support frame 20. Simultaneously, the frame elevates the items, preventing them from being constantly submerged. This also prevents water leakage due to packaging seal failure, which could seep into critical equipment areas such as the cabin circuit boards, causing electrical system malfunctions and triggering a series of chain reactions. Such leakage could severely damage the aircraft's structure and electronic systems, posing a significant threat to flight safety. Therefore, this cardboard box is suitable for air transport of water-containing products, providing an effective solution for packaging water-bearing goods in air transport and preventing items from being soaked in water and water leakage from harming the aircraft.
