Description

Technical Field

[0001] The utility model relates to the field of packaging boxes, and particularly to a novel packaging box. Background Art

[0002] As the name implies, a packaging box is a box used to package products. It can be classified by materials such as paper boxes, iron boxes, wooden boxes, cloth boxes, leather boxes, acrylic boxes, corrugated packaging boxes, PVC boxes, etc. It can also be classified by the name of the product such as mooncake boxes, tea boxes, wolfberry boxes, candy boxes, delicate gift boxes, local specialty boxes, wine boxes, chocolate boxes, food, medicine, health care product boxes, food packaging boxes, tea packaging boxes, stationery boxes, etc.

[0003] In real life, the most common one is the corrugated paper packaging box. The corrugated paper packaging box is also a kind of packaging product with the widest application. Its usage has always been the first among various packaging products. The corrugated paper packaging box has become the main force of transportation packaging with its superior performance and good processing performance. It also belongs to green environmental protection products and is beneficial to environmental protection. However, the existing packaging boxes in the products have the following defects when being folded:

[0004] Since the corrugated paper packaging box needs to be folded into the shape of the packaging box after being manufactured in the early stage, and then the items are placed in the packaging box. When the existing packaging box is folded, it needs to be coated with glue on the surface or nails are driven at multiple corners after folding to enhance the stability effect. However, this method not only increases the process in the process of folding the packaging box, but also increases the manufacturing cost. At the same time, the glue applied contains chemical elements, which may be harmful to the human body and the environment to a certain extent, and nailing will also increase metal waste, etc., which is not conducive to subsequent recycling. Content of the Utility Model

[0005] The utility model aims to provide a novel packaging box, which is mainly used to solve the technical problem that the existing products increase the process and cost due to gluing and nailing.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0007] A new type of packaging box, including a bottom plate, with a first side plate and a second side plate that are folded upwardly connected to the front end and the rear end of the bottom plate respectively. Side covers are provided on the left and right sides of the bottom plate and are folded upwardly. At both ends of the side covers, there are first folding plates and second folding plates that are folded upwardly and are attached to the inner walls of the first side plate and the second side plate. On the opposite side of the first folding plate, there is a clamping component for connecting the two first folding plates together. On the side of the first side plate away from the bottom plate, there is a folding plate that is folded inwardly, and the first folding plate is located between the folding plate and the first side plate. At one end of the second side plate away from the side cover, there is a cover plate for sealing. On both sides of the cover plate, there are support plates that are folded upwardly and are attached to the inner wall of the side cover. At one end of the cover plate away from the second side plate, there is a fixing plate.

[0008] The working principle and beneficial effects of the present utility model:

[0009] 1. Working principle: When the packaging box needs to be folded, first, fold the side covers on both sides of the bottom plate upwardly. The side covers drive the first folding plates and the second folding plates. At this time, fold the first folding plates along the side edges of the side covers towards the direction close to the bottom plate to form a 90-degree angle with the side covers. At the same time, during the folding process, connect the two first folding plates through the clamping component. Further, fold the first side plate upwardly along the side edge of the bottom plate to form a 90-degree angle with the bottom plate. After the first side plate is folded, flip the folding plate so that the folding plate is folded towards the side of the bottom plate along the side edge of the first folding plate until it is perpendicular to the bottom plate. At this time, the first folding plate is located between the folding plate and the first side plate. Then, flip the second folding plate so that the second folding plate is folded inwardly along the side edge of the side cover until it is perpendicular to the second side plate. After the second folding plate is folded, fold the second side plate upwardly along the other side edge of the bottom plate until it is perpendicular to the bottom plate. After the second side plate is folded, fold the support plates on both sides of the cover plate upwardly to be perpendicular to the cover plate. Then, flip the cover plate and fold it along the side edge of the second side plate. During this process, the fixing plate can be folded along the other side edge of the cover plate so that the fixing plate is perpendicular to the cover plate. When the cover plate is flipped along the side edge of the second side plate by a certain angle, the support plates move downward along the inner wall of the side plate, and the fixing plate moves downward along the side of the folding plate close to the bottom plate. When the cover plate is flipped to be perpendicular to the second side plate, one ends of the fixing plate and the support plates abut against the upper surface of the bottom plate, and then the folding of the installation box is completed.

[0010] 2. Beneficial effects:

[0011] (1) The existing product solves the technical problem of poor stability after the packaging box is folded by applying glue and nailing to the packaging box. However, this method not only increases the processes during the folding of the packaging box but also increases the manufacturing cost. At the same time, the applied glue contains chemical elements, which may be harmful to the human body and the environment. Nailing also increases metal waste, etc., which is not conducive to subsequent recycling. This solution effectively improves the stability of the packaging box after folding by setting technical features such as the first side plate, the second side plate, the first folding plate, and the second folding plate and using them in combination for folding, avoiding the phenomenon of applying glue and nailing for fixation after the packaging box is folded in the prior art, reducing the manufacturing cost, and solving the technical problems of increased processes and costs due to applying glue and nailing in the existing product.

[0012] (2) By setting a clamping component at the end of the first folding plate, the arc-shaped elastic piece abuts against the inner wall of the installation groove to form a clamping connection, ensuring that when folding the packaging box, the folded first folding plate can be pre-fixed, facilitating the subsequent operation of the personnel folding the installation box, which is fast and convenient and improves the folding efficiency.

[0013] Preferably, the clamping component includes a plug inserted on one side of one of the first folding plates, a slot matching the plug is opened on the opposite side of the other first folding plate, an installation groove is opened on the inner wall of the slot, a placement groove is opened on one side of the plug, an arc-shaped elastic piece is installed on the inner wall of the placement groove. When the plug at one end of one of the first folding plates slides along the slot into the installation groove, at the same time the slot squeezes the arc-shaped elastic piece, causing one end of the arc-shaped elastic piece to slide along the lower side wall of the placement groove. When the plug is inserted into the predetermined position, the arc-shaped elastic piece rebounds and pops up. At this time, if the two first folding plates are pulled, the plug moves out along the slot, and one end of the inclined baffle will block the arc-shaped elastic piece. Due to the fracture line set in the middle position of the arc-shaped elastic piece, the inclined baffle will push up the side of the arc-shaped elastic piece close to the inclined baffle along the fracture line, making the arc-shaped elastic piece abut against the inner wall of the installation groove to form a clamping connection, ensuring that when folding the packaging box, the folded first folding plate can play a role in pre-fixation, facilitating the subsequent operation of the personnel folding the installation box, which is fast and convenient and improves the folding efficiency.

[0014] Preferably, one end of the arc-shaped elastic piece is fixedly connected to the lower side wall of the placement groove, and the other end is slidably connected to the lower side wall of the placement groove and is close to the side wall of the placement groove, which can effectively ensure that after the arc-shaped elastic piece is squeezed, one end thereof will not abut against the side wall of the placement groove, resulting in the phenomenon that the arc-shaped elastic piece cannot be normally squeezed and deformed.

[0015] Preferably, a fracture line is set in the middle position of the arc-shaped elastic piece. The setting of the fracture line effectively ensures that after the arc-shaped elastic piece is squeezed, it can be deformed to achieve the clamping effect, and at the same time, it will not cause the phenomenon that it cannot be squeezed and deformed due to the certain hardness of the arc-shaped elastic piece.

[0016] Preferably, an inclined baffle is connected to the inner wall of the installation groove. One end of the inclined baffle is flush with the opening of the placement groove, which can effectively block the arc-shaped elastic piece and squeeze the arc-shaped elastic piece, further deforming the arc-shaped elastic piece to achieve the clamping effect.

[0017] Preferably, a guiding groove is provided at the end of the insertion plate away from the first folding plate. The provision of the guiding groove facilitates the smooth insertion of the insertion plate into the insertion slot, facilitates the operation of personnel, and saves the time for folding the packaging box.

[0018] Preferably, the material of the clamping component can be the same as that of the packaging box. Selecting the same material as the packaging box can effectively save the manufacturing cost, and the same material will not affect the specific implementation of the device. Combining with the certain shaping performance of corrugated paper, the expected effect can be effectively achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] As Figures 1 - 6 shown, a new type of packaging box includes a bottom plate 1. The front end and the rear end of the bottom plate 1 are connected with a first side plate 2 and a second side plate 3 that are folded upward. The left and right sides of the bottom plate 1 are provided with side covers 4 that are folded upward. The two ends of the side cover 4 are connected with a first folding plate 5 and a second folding plate 6 that are folded upward and are attached to the inner walls of the first side plate 2 and the second side plate 3. On the opposite side of the first folding plate 5, there is a clamping component for connecting the two first folding plates 5 together. The material of the clamping component can be the same as that of the packaging box. Selecting the same material as the packaging box can effectively save the production cost, and the same material will not affect the specific implementation of the device. Combining with the fact that corrugated paper has certain shaping performance, the expected effect can be effectively achieved;

[0028] The clamping component includes an insertion plate 11 connected to one side of one of the first folding plates 5. A guiding groove is opened at the end of the insertion plate 11 far from the first folding plate 5. A slot 12 matching the insertion plate 11 is opened on the opposite side of the other first folding plate 5. An installation groove 13 is opened on the inner wall of the slot 12. An inclined baffle 17 is connected to the inner wall of the installation groove 13. One end of the inclined baffle 17 is flush with the opening of the placement groove 14. A placement groove 14 is opened on one side of the insertion plate 11. An arc-shaped elastic piece 15 is installed on the inner wall of the placement groove 14. A break line 16 is arranged at the middle position of the arc-shaped elastic piece 15. One end of the arc-shaped elastic piece 15 is fixedly connected to the lower side wall of the placement groove 14, and the other end is slidably connected to the lower side wall of the placement groove 14 and is close to the side wall of the placement groove 14, which ensures that when folding the packaging box, it can play a role in pre-fixing the folded first folding plate 5, facilitating the subsequent operation of the personnel folding the installation box, which is fast and convenient, and improves the folding efficiency. The side of the first side plate 2 far from the bottom plate 1 is connected with a folding plate 7 that is folded inward, and the first folding plate 5 is located between the folding plate 7 and the first side plate 2. The end of the second side plate 3 far from the side cover 4 is connected with a cover plate 8 for sealing. The two sides of the cover plate 8 are connected with support plates 9 that are folded upward, and the support plates 9 are attached to the inner wall of the side cover 4. The end of the cover plate 8 far from the second side plate 3 is connected with a fixing plate 10.

[0029] As can be seen from the above, the specific implementation manner of the present invention is as follows:

[0030] When the packaging box needs to be folded, first, fold up the side covers 4 on both sides of the bottom plate 1. The side covers 4 drive the first folding plate 5 and the second folding plate 6. At this time, fold the first folding plate 5 along the side line of the side cover 4 towards the direction close to the bottom plate 1 to form a 90-degree angle with the side cover 4. At the same time, during the folding process, the insertion plate 11 at one end of one of the first folding plates 5 slides along the slot 12 into the installation groove 13. At the same time, the slot 12 squeezes the arc-shaped elastic piece 15, so that one end of the arc-shaped elastic piece 15 slides along the lower side wall of the placement groove 14. When the insertion plate 11 is inserted into the predetermined position, the arc-shaped elastic piece 15 resets and bounces up. At this time, if the two first folding plates 5 are pulled, the insertion plate 11 moves out along the slot 12, and one end of the inclined baffle 17 will block the arc-shaped elastic piece 15. Due to the break line 16 set in the middle position of the arc-shaped elastic piece 15, the inclined baffle 17 will push up one side of the arc-shaped elastic piece 15 close to the inclined baffle 17 along the break line 16, so that the top surface of the arc-shaped elastic piece 15 abuts against the inner wall of the installation groove 13 to form a clamping connection, ensuring that when folding the packaging box, the folded first folding plate 5 can be pre-fixed, facilitating the subsequent operation of the personnel folding the installation box, which is fast and convenient and improves the folding efficiency.

[0031] After the first folding plate 5 is pre-fixed, further fold up the first side plate 2 along the side line of the bottom plate 1 and form a 90-degree angle with the bottom plate 1. After the first side plate 2 is folded up, flip the folding plate 7 so that the folding plate 7 folds along the side line of the first folding plate 5 to one side of the bottom plate 1 until it is perpendicular to the bottom plate 1. At this time, the first folding plate 5 is located between the folding plate 7 and the first side plate 2. Then flip the second folding plate 6 so that the second folding plate 6 folds inward along the side line of the side cover 4 until it is perpendicular to the second side plate 3. After the second folding plate 6 is folded, fold up the second side plate 3 along the other side line of the bottom plate 1 until it is perpendicular to the bottom plate 1. After the second side plate 3 is folded, fold up the support plates 9 on both sides of the cover plate 8 to be perpendicular to the cover plate 8. Then flip the cover plate 8 and fold it along the side line of the second side plate 3. During this process, the fixing plate 10 can be folded along the other side line of the cover plate 8 so that the fixing plate 10 is perpendicular to the cover plate 8. When the cover plate 8 is flipped along the side line of the second side plate 3 by a certain angle, the support plate 9 moves downward along the inner wall of the side cover 4, and the fixing plate 10 moves downward along the side of the folding plate 7 close to the bottom plate 1. When the cover plate 8 is flipped to be perpendicular to the second side plate 3, one ends of the fixing plate 10 and the support plate 9 abut against the upper end surface of the bottom plate 1, and then the folding of the installation box is completed;

[0032] This folding method of the packaging box can effectively improve the stability of the folded packaging box, avoid the phenomenon of gluing and nailing for fixing after folding the packaging box in the prior art, and reduce the manufacturing cost.

[0033] The above are only the embodiments of the present utility model, and common general knowledge such as specific structures and characteristics known in the solutions is not described in detail herein. It should be noted that for those skilled in the art, without departing from the structure of the present utility model, several modifications and improvements can be made, and these should also be regarded as the protection scope of the present utility model, and these will not affect the implementation effect of the present utility model and the practicality of the patent. The protection scope claimed in this application shall be subject to the content of its claims, and the specific implementation manners and the like recorded in the specification can be used to interpret the content of the claims.
