Detailed Implementation

[0023] 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.

[0024] The purpose of this utility model is to provide a dinner plate packaging box to solve the problems existing in the prior art, achieve environmental protection, improve resource utilization, and provide good protection.

[0025] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1-3As shown, this embodiment provides a dinner plate packaging box, including a one-piece molded body that can be folded into a box shape. This eliminates the need for complex gluing or assembly operations, significantly improving packaging efficiency. It is also easy to carry and transport, reducing logistics costs during the packaging process. The body includes a lower base plate 1, a retaining plate element, a side top element, and two side wall elements. The lower base plate 1 forms the bottom surface of the box. The two side wall elements are symmetrically connected to one side of the lower base plate 1 and can rotate around the lower base plate 1 to form two opposite side walls of the box. The retaining plate element and the side top element are respectively connected to the other two sides of the lower base plate 1. The retaining plate element can rotate around the lower base plate 1 to form one side wall of the box and a slot 6 for supporting the dinner plate. The slot 6 is located inside the box to accommodate fragile tableware such as dinner plates. The system provides fixation and support, thereby suspending and protecting fragile tableware such as plates, dispersing and absorbing external pressure, and keeping the plates and other fragile tableware fixed within the box. It has excellent shock resistance and will not collide with adjacent plates or the outer wall of the box, effectively preventing impact vibration during transportation, thus protecting the plates and other fragile tableware. The side top element can rotate around the bottom plate 1 to form one side wall and the top surface of the box, thereby forming a stable box with a certain load-bearing capacity, achieving protection of the outer perimeter of the plates and other fragile tableware, effectively protecting them from damage during transportation, storage, and display. At the same time, those skilled in the art can make corresponding adjustments and designs according to different product sizes and shapes, exhibiting strong adaptability.

[0027] Specifically, the lower base plate 1 is connected to each side wall component, the lower base plate 1 is connected to the side top component, and the lower base plate 1 is connected to the card plate component through the first fold line, which facilitates the rotation and folding of the side wall component, the side top component and the card plate to form a box.

[0028] The card plate element includes a first side plate 2, a hollow wall plate 3, and an inner end plate 7. The first side of the first side plate 2 is connected to the lower bottom plate 1 by a first fold line, the second side of the first side plate 2 is connected to the first side of the hollow wall plate 3 by a second fold line, and the second side of the hollow wall plate 3 is connected to the first side of the inner end plate 7 by a third fold line. A slot 6 is formed in the middle of the hollow wall plate 3. The first side plate 2 can rotate around the first fold line to be perpendicular to the lower bottom plate 1, and the first side plate 2 is used to form the front side wall of the box. The hollow wall plate 3 can rotate around the second fold line to cover the lower bottom plate 1, and the hollow wall plate 3 is used to form a support layer in the middle of the box. The inner end plate 7 can rotate around the third fold line to be perpendicular to the lower bottom plate 1 and parallel to the first side plate 2, and the inner end plate 7 is used to support the inner side of the rear side wall of the box. This ensures connection stability and improves overall strength.

[0029] In the direction parallel to the second fold line, the lengths of the first side plate 2, the hollow wall plate 3, and the end inner plate 7 are all equal.

[0030] The hollow wall panel 3 includes two unit panels symmetrically arranged along the fourth fold line. The two unit panels can rotate relative to each other around the fourth fold line to adjust the included angle between the two unit panels. The fourth fold line is parallel to the second fold line. Each of the two unit panels is provided with a slot 6. The two slots 6 are used to hold the two sides of the plate respectively, and the space between the two unit panels is used to accommodate the plate. The two slots 6 are symmetrically arranged and are trapezoidal. The length of the bottom edge of the two slots 6 closer to the fourth fold line is shorter than the length of the bottom edge farther from the fourth fold line, which makes it easier to securely hold the plate between the two slots 6. When the hollow wall panel 3 is rotated to be above the lower base plate 1, the fourth fold line is lower than the second and third fold lines, which makes the upper surface formed by the two unit panels concave, thus providing effective and stable support for the plate and preventing the plate from shaking during transportation. This layout not only makes full use of the internal space of the box, but also ensures that the hollow wall panel 3 can effectively play its role in enhancing strength and cushioning, thereby effectively protecting the plates from damage. No adhesive is needed, saving process and cost. The regular shape of the box is easy to stack, the packaging is sturdy, and it has a certain impact resistance, which can withstand most of the impacts encountered by the plates during transportation and distribution, ensuring the safety of the plates inside.

[0031] Through the above design, this embodiment achieves a reasonable structural design for the box and inner lining, effectively protecting the product from damage during transportation, storage, and display. This protective effect is particularly significant for fragile items such as dinner plates.

[0032] Each unit plate has a foot wing 4 at both ends, and the foot wing 4 is connected to the unit plate by a fifth fold line. The foot wing 4 can rotate around the fifth fold line to be perpendicular to the unit plate. When the unit plate is rotated to be above the bottom plate 1, the foot wing 4 can support between the unit plate and the bottom plate 1. Thus, the four foot wing 4 support the two unit plates below, so that the lower end of the unit plate does not directly contact the bottom plate 1, thereby supporting the plate and keeping the plate suspended in the box to avoid damage to the plate due to collision during transportation.

[0033] The fourth aileron is triangular and provides stable support.

[0034] Two first locking grooves 5 are symmetrically provided on the hollow wall panel 3. The two first locking grooves 5 are arranged in parallel and are perpendicular to the second fold line. They are respectively located near the two ends of the second fold line. After the two side wall elements rotate around the first fold line, they can be inserted into the two first locking grooves 5 respectively, thereby realizing the insertion and fixing between the side wall elements and the card plate elements and improving the overall connection stability.

[0035] The two sidewall components have the same structure and each includes a second side plate 9, a connecting plate 10, and a first tongue 11. The two second side plates 9 are the same size and symmetrically arranged. The first side of the second side plate 9 is connected to the lower base plate 1 by a first fold line, the second side of the second side plate 9 is connected to the first side of the connecting plate 10 by a sixth fold line, and the second side of the connecting plate 10 is connected to the first side of the first tongue 11 by a seventh fold line. The second side plate 9 can rotate around the first fold line to be perpendicular to the lower base plate 1, so that the two second side plates 9 respectively form the left and right sidewalls of the box. The connecting plate 10 can rotate around the sixth fold line to be parallel to the lower base plate 1 and located above the lower base plate 1. The first tongue 11 can rotate around the seventh fold line to be perpendicular to the lower base plate 1 and inserted into the first locking groove 5 to realize the insertion and fixation between the sidewall components and the locking plate components, thereby improving the overall connection stability.

[0036] The two first tongues 11 are symmetrically arranged, and the first tongues 11 have an irregular shape. The length of the first side of the first tongue 11 is greater than the length of the second side of the first tongue 11, which makes it easier for the first tongue 11 to be inserted into the first lock groove 5.

[0037] The side-top component includes a third side plate 12, an upper top plate 13, a front cover plate 14, and a second tongue 15. The third side plate 12 is the same size as the first side plate 2 and is symmetrically arranged. In the direction perpendicular to the second fold line, the length of the upper top plate 13 is less than the length of the hollow wall panel 3, and the length of the front cover plate 14 is greater than the length of the first side plate 2 and also greater than the length of the inner end plate 7. The length of the inner end plate 7 is equal to the length of the first side plate 2. The first side of the third side plate 12 is connected to the lower bottom plate 1 by a first fold line, the second side of the third side plate 12 is connected to the first side of the upper top plate 13 by an eighth fold line, the second side of the upper top plate 13 is connected to the first side of the front cover plate 14 by a ninth fold line, and the second side of the front cover plate 14 is connected to the first side of the second tongue 15 by a tenth fold line. The third side plate 12 can rotate around the first fold line to be perpendicular to the lower bottom plate 1, thereby forming a box body. The rear sidewall, together with the first side plate 2 and two second side plates 9, protects the four sides of the plate. The top plate 13 can rotate around the eighth fold line to be perpendicular to the third side plate 12 and parallel to the bottom plate 1, thus forming the top surface of the box. The front cover plate 14 can rotate around the ninth fold line to be perpendicular to the bottom plate 1 and the top plate 13 and parallel to the third side plate 12, thus forming the front sidewall of the box. The flipped and folded front cover plate 14 is parallel and close to the flipped and folded first side plate 2, and the flipped and folded third side plate 12 is parallel and close to the flipped and folded inner end plate 7. A second locking groove 8 is provided at the first fold line between the bottom plate 1 and the card plate element. The tongue can rotate around the tenth fold line to be perpendicular to the front cover plate 14 and inserted into the second locking groove 8 to achieve insertion, improving the structural stability of the box and providing better protection. At the same time, the flip-top design of the box makes it easy for consumers to open and close, improving the convenience of use.

[0038] In the direction parallel to the second fold line, the lengths of the second side plate 9, the top plate 13, and the front cover plate 14 are all equal and all greater than the length of the first side plate 2.

[0039] The main body is made of corrugated cardboard, which is environmentally friendly and has good cushioning properties. The corrugated cardboard supports suspend and protect fragile tableware such as plates, distributing and absorbing external pressure to keep them fixed within the box. This effectively prevents impacts and vibrations during transportation, thus protecting the tableware. Furthermore, because the entire box is made of biodegradable paper material, no non-biodegradable materials such as glue are needed, resulting in good environmental performance. After use, the box can be easily recycled and reused, reducing waste generation.

[0040] As a specific design, in the direction parallel to the sixth fold line, the lengths of the two second side plates 9 are equal and equal to the length of the bottom plate 1, with a length value of 237mm; in the direction parallel to the second fold line, the length of the first side plate 2 is 245mm, the length of the third side plate 12 is 253mm, and the length of the bottom plate 1 is greater than the length of the first side plate 2 and equal to the length of the third side plate 12, that is, the length of the bottom plate 1 is 253mm, which facilitates the cooperation between the side plates after folding and avoids mutual interference.
