Description

Technical Field

[0001] This invention relates to the field of packaging, and in particular to a packaging cardboard box. Background Technology

[0002] Packaging boxes are used to package products, making them portable and less prone to damage. Existing packaging boxes generally consist of a box body and a lid. The box body includes a base plate and several support plates connected to the base plate, while the lid includes a top plate and several side plates connected to the top plate. Some box bodies and lids are connected together, while others are separate. Regardless of whether the box body and lid are connected or separate, the side plates of the lid are generally fitted onto the outside of the box body. In a few cases, the side plates of the lid are located inside the box, but these do not provide any restraint for the product inside. If there is a gap between the product inside the box and the lid, the product inside the box is prone to impacting the lid or the box's support plates when the packaging box shakes, thus compromising product protection. Furthermore, the top plate of the lid is prone to collapse under external force, making the product inside the box more susceptible to damage. Summary of the Invention

[0003] This invention addresses the technical problems existing in the prior art by providing a packaging cardboard box that can improve the protective effect of products.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a packaging paper box, including a box body and a lid, the box body including a bottom plate and a plurality of support plates connected to the bottom plate, the lid including a top plate and a plurality of side plates connected to the top plate; at least two side plates of the lid are wholly or partially inserted into the box body and can hold the product inside the box body.

[0005] Furthermore, at least three side panels of the cover are fully or partially inserted into the box body and can hold the product inside the box body.

[0006] Furthermore, the plurality of side panels include a left side panel and a right side panel, which are wholly or partially inserted into the box body and can hold the product inside the box body.

[0007] Furthermore, the left and right side panels are completely inserted into the box and are folded; or, the left and right side panels are partially inserted into the box, and the portions of the left and right side panels located in the box are folded.

[0008] Furthermore, the folding structure is V-shaped, W-shaped, or N-shaped on the outside of the box, with its two ends distributed on the left and right, and the inner end of its two ends connected to the top plate.

[0009] Furthermore, the rear edge of the top plate is connected to the top edge of a support plate of the box body, and the plurality of side plates also include a front side plate, which is wholly or partially inserted into the box body and can hold the product inside the box body.

[0010] Furthermore, the front panel includes a first panel and a second panel, which are separated from each other on the left and right sides; the first panel enters the box and can hold the product inside the box, while the second panel fits onto the outer side of the box.

[0011] Furthermore, there are two second plates, which are located on the left and right sides of the first plate, respectively; a first flap is connected to the opposite outer edge of each of the two second plates, and the two first flaps are inserted from front to back into the gaps formed at the left and right ends of the box body.

[0012] Furthermore, the plurality of support plates include a front support plate, a rear support plate, a left support plate, and a right support plate, with the top edge of the rear support plate connected to the rear edge of the top plate; a second flap is connected to the left and right sides of the front support plate, and a third flap is connected to the left and right sides of the rear support plate; the left and right support plates are folded to form the gaps that extend from the front to the back, and the second and third flaps on the same side are wrapped within them.

[0013] Furthermore, at least one support plate of the box body is provided with an observation port, and / or the box body and the lid body are integrally folded from the same cardboard.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Since at least two side plates of the lid are fully or partially inserted into the box and can hold the product inside the box, the present invention can not only limit the product inside the box by using at least two side plates of the lid fully or partially inserted into the box to prevent the product from hitting the lid or box when the packaging box shakes, but also support the top plate of the lid by using at least two side plates of the lid fully or partially inserted into the box to prevent the top plate from collapsing downward under force and causing damage to the product.

[0016] 2. As a preferred embodiment, at least three side plates of the cover are fully or partially inserted into the box and can hold the product inside the box, so that the cover can limit the product inside the box at least three points and also limit the top plate at least three points, thereby improving the limiting effect of the cover on the product and the supporting effect on the top plate.

[0017] 3. As a preferred embodiment, the left and right side panels are fully or partially inserted into the box body, supporting the product inside. This allows the lid to limit the product's left and right ends and support the top panel's left and right ends, resulting in better limiting and support effects. Specifically, the left and right side panels are fully inserted into the box body in a folded structure, or partially inserted into the box body with folded portions. This allows the invention to further enhance the limiting structure for the product and the support effect for the top panel using folded structures.

[0018] 4. The plurality of side panels also includes a front side panel, which is wholly or partially inserted into the box body and can hold the product inside the box body, so that the front side panel can cooperate with the left side panel and the right side panel to form a three-point restraint on the product and a three-point support for the top panel. In particular, the front side panel includes a first plate and two second plates, which are separate from the first plate and located on the left and right sides of the first plate; the first plate enters the box body and can hold the product inside the box body, and the two second plates cooperate with the outer side of the box body, so that the front side panel retains its basic functions and also has the functions of restraining the product and supporting the top panel.

[0019] 5. There are two second plates, which are located on the left and right sides of the first plate respectively; a first flap is connected to the opposite outer edge of the two second plates, and the two first flaps are inserted from front to back into the gaps formed at the left and right ends of the box body, so that the lid and the box body can be restricted from opening without the need for adhesive connection.

[0020] 6. At least one support plate of the box body is provided with an observation port to facilitate observation of the product inside the box.

[0021] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the packaging box of the present invention is not limited to the embodiments. Attached Figure Description

[0027] For an example, please refer to [link / reference]. Figures 1-5 As shown, a packaging box of the present invention includes a box body 1 and a cover body 2. The box body 1 includes a bottom plate 11 and a plurality of support plates connected to the bottom plate 11. The cover body 2 includes a top plate 21 and a plurality of side plates connected to the top plate 21. At least two side plates of the cover body 2 are wholly or partially inserted into the box body 1 and can hold the product inside the box body 1.

[0028] In this embodiment, the at least two side panels include a left side panel 22 and a right side panel 23. The left side panel 22 and the right side panel 23 are fully or partially inserted into the box body 1 and can hold the product inside the box body 1.

[0029] In this embodiment, the cover 2 has three side panels that are wholly or partially inserted into the box 1 and can hold the product inside the box 1. The rear of the top plate 21 is connected to the top edge of a support plate of the box 1. In addition to the left side plate 22 and the right side plate 23, the three side panels also include a front side plate 24, which is wholly or partially inserted into the box 1 and can hold the product inside the box 1.

[0030] In this embodiment, the left side panel 22 and the right side panel 23 are completely inserted into the box body 1 and are folded. In other embodiments, the left side panel 22 and the right side panel 23 are partially inserted into the box body 1, and the portions of the left side panel 22 and the right side panel 23 located in the box body 1 are folded. The folded structures are V-shaped (or W-shaped or N-shaped, etc.) outside the box body 1, with their two ends distributed to the left and right, and the innermost end of each end connected to the top panel 21.

[0031] In this embodiment, the front panel 24 includes a first panel 241 and a second panel 242, which are separated to the left and right. The first panel 241 enters the box 1 and supports the product inside the box 1, while the second panel 242 fits onto the outer side of the box 1. The number of second panels 242 is specifically two, but not limited to this. The two second panels 242 are located on the left and right sides of the first panel 241, respectively. The first panel 241 is trapezoidal, but not limited to this, and its short side is connected to the front side of the top panel 21.

[0032] In this embodiment, a first flap 2421 is connected to the opposite outer edge of each of the two second plates 242, and the two first flaps 2421 are respectively inserted into the gaps 16 formed at the left and right ends of the box body 1 from front to back.

[0033] In this embodiment, the plurality of support plates include a front support plate 12, a rear support plate 13, a left support plate 14, and a right support plate 15. The top edge of the rear support plate 13 is connected to the rear edge of the top plate 21. A second flap is connected to each of the left and right sides of the front support plate 12, and a third flap 131 is connected to each of the left and right sides of the rear support plate 13. The left support plate 14 and the right support plate 15 are folded to form the gap 16 that extends outwards and backwards, and the second flap and the third flap 131 on the same side are wrapped in it.

[0034] In this embodiment, at least one support plate of the box body 1 is provided with an observation port 132. Specifically, the rear support plate 13 of the box body 1 is provided with the observation port 132, and the observation port 132 is located at the bottom left end of the rear support plate 13.

[0035] The present invention provides a packaging box, wherein the box body 1 and the lid 2 are integrally folded from the same cardboard, and its unfolded state is as follows. Figure 1 As shown. When folding, first complete the folding of box body 1: fold the four support plates (front support plate 12, rear support plate 13, left support plate 14, and right support plate 15) connected to the four sides of the base plate 11 upwards along the creases to form a vertical state. Fold the second flaps on both sides of the front support plate 12 forward, and fold the third flaps 131 on both sides of the rear support plate 13 backward, as shown. Figure 2 As shown; next, fold the left support plate 14 and the right support plate 15 inward and downward along their central creases, respectively, so that gaps 16 are formed at the left and right ends of the box body 1, and wrap the second and third flaps 131 on the same side inside them, as shown. Figure 3 As shown. When packaging the product, first place the product (specifically electronic module 3, but not limited to this) into box 1, as follows. Figure 4 As shown; next, fold the cover 2: fold the left side panel 22 and the right side panel 23 into V-shapes respectively, fold the first panel 241 downwards, and fold the two second panels 242 and their connected first flaps 2421 into L-shapes respectively, as shown. Figure 5 As shown; finally, cover the lid 2: insert the first plate 241 into the box 1 and hold it against the electronic product, fold the left side plate 22 and the right side plate 23 and insert them into the box 1 and hold it against the electronic product, fold the two second plates 242 downward so that they are located outside the front support plate 12 of the box 1, and insert the first flaps 2421 on the two second plates 242 into the gaps 16 at the left and right ends of the box 1 respectively.

[0036] The present invention discloses a packaging box in which the first plate 241 of the front side plate 24, the left side plate 22, and the right side plate 23 provide three-point restraint for the product and three-point support for the top plate 21. This prevents the product from impacting the lid 2 or the box body 1 when the packaging box shakes, and also makes the top plate 21 less likely to collapse downwards under force, thus preventing product damage. In addition, the left side plate 22 and the right side plate 23 are folded structures inside the box body 1, which not only improves strength, but also reduces the gap between them and the corresponding inner surfaces of the box body 1 by slightly unfolding or having a tendency to unfold outwards. This improves the restraint effect of the folded structure on the product and the support effect on the top plate 21.

[0037] The above embodiments are only used to further illustrate a packaging box of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the technical solution of the present invention.
