Description

Technical Field

[0001] The utility model relates to the technical field of packaging cartons, in particular to a lightweight and compression-resistant packaging carton. Background Art

[0002] A packaging carton is made of paper products and is a tool for packaging various items. Cartons are subdivided into various types of packaging such as paper boxes, color boxes, color cartons, and extra-large and oddly-shaped beer boxes; the existing packaging cartons used for express delivery are prone to damage due to the violent sorting of express delivery, resulting in damage to the items inside the carton. Therefore, the packaging cartons used for packing express delivery need to meet the requirements of lightweight transportation while also having certain requirements for the compression resistance of the packaging carton, so as to avoid the packaging box being flattened and damaging the internal packaged items during the violent sorting of express delivery.

[0003] For example, the patent with the publication number CN220949095U discloses a packaging carton with good compression resistance, including a main body component, the main body component includes a bottom plate, side plates and a top plate, the bottom plate is arranged below the side plates, the top plate is arranged above the top plate, the bottom plate, side plates and top plate are of an integral structure, and are separated by creases between every two; compression-resistant components are respectively arranged on the bottom plate, side plates and top plate; a support plate is arranged at the inner bottom end of the main body component. Through the setting of the compression-resistant components, the cooperation between the compression-resistant components and the main body component is used to play a compression-resistant role in the entire carton structure. The compression-resistant components mainly play a role in protecting and resisting compression at the corners of the carton, preventing the packaging carton for express delivery from being damaged due to the violent sorting of express delivery, and thus effectively protecting the items inside the carton.

[0004] However, the packaging carton in the above technology still has the following problems:

[0005] Although the above technology plays a role in protecting and resisting compression at the corners of the packaging carton through the compression-resistant components, during the sorting and transportation of express delivery, the packaging carton may not be placed normally, and it is easy for the sides and the upper and lower surfaces of the packaging carton to be squeezed by the corners of other cartons, resulting in the sides or the upper and lower surfaces of the packaging carton being squeezed and sunken inward, causing damage to the internal packaged items, and the compression resistance is poor. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a lightweight and compression-resistant packaging carton, for example: it can carry out compression resistance protection on the periphery and the upper and lower surfaces of the packaging carton, and further improve the compression resistance of the packaging carton.

[0007] To achieve the above object, the present utility model provides the following technical solution: A lightweight and compression-resistant packaging carton, comprising a box body, wherein side strengthening ribs are provided inside the box body, and the side strengthening ribs are respectively located on the inner walls of the four side surfaces inside the box body. Support ribs are connected between every two adjacent side strengthening ribs. Bottom compression blocks and top compression blocks are respectively connected to the upper and lower ends of the four side strengthening ribs and the four support ribs. The bottom compression blocks are located at the bottom of the box body, and the top compression blocks are located at the top of the box body.

[0008] Further, the side strengthening ribs are in a cross structure and are fixedly connected to the inner wall of the side surface of the box body.

[0009] Further, the cross-section of the support rib is L-shaped, and the outer wall of the L-shape of the support rib is fixedly connected to the inner wall of the bending part of the box body.

[0010] Further, both the bottom compression blocks and the top compression blocks are located inside the four side strengthening ribs and the four support ribs and are slidably connected to the inner sides of the four side strengthening ribs and the four support ribs.

[0011] Further, both the bottom compression blocks and the top compression blocks are foam blocks made of polystyrene.

[0012] Further, a storage groove is provided at the central position on the side of the bottom compression block close to the top compression block.

[0013] Further, a positioning groove is provided at the central position on the side of the top compression block close to the bottom compression block.

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

[0015] For this lightweight and compression-resistant packaging carton, through the side strengthening ribs, the bottom compression blocks and the top compression blocks, the stress intensity on the sides and the upper and lower sides of the carton can be enhanced, reducing the structural integrity of the packaging carton when it is squeezed and collided with other packaging boxes during express delivery, and reducing the damage rate of the internal packaged objects.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] Please refer to Figure 1 - Figure 5 , a lightweight and compression-resistant packaging carton, including a box body 1, with side strengthening ribs 2 provided inside the box body 1. The side strengthening ribs 2 are respectively located on the inner walls of the four sides inside the box body 1. Support ribs 3 are connected between adjacent two side strengthening ribs 2. The upper and lower ends of the four side strengthening ribs 2 and the four support ribs 3 are respectively connected with a bottom compression block 4 and a top compression block 5. The bottom compression block 4 is located at the bottom of the box body 1, and the top compression block 5 is located at the top of the box body 1.

[0024] As Figure 1 - Figure 5 shown, a lightweight and compression-resistant packaging carton in the present utility model is similar in structure to the existing lightweight and compression-resistant packaging cartons. For example, a packaging carton with good compression resistance disclosed in the patent with the publication number CN220949095U. The main improvement point of the present utility model is to further improve the compression resistance of the packaging box body 1. As Figures 1 to 5 shown, when the lightweight and compression-resistant packaging carton in the present utility model is in use, the bottom compression block 4 is placed at the bottom of the box body 1. Subsequently, the object to be packaged is placed inside the box body 1 and on the bottom compression block 4. Then, the top compression block 5 is covered above the object, and the upper cover of the box body 1 is covered and sealed. During handling, when the corners of other box bodies 1 squeeze the upper and lower surfaces of the box body 1, the bottom compression block 4 and the top compression block 5 can protect the internal object from being squeezed and damaged. When the side of the box body 1 is squeezed, the side strengthening ribs 2 can, to a certain extent, reinforce the side of the box body 1 and reduce the possibility of the side of the box body 1 being deformed by squeezing. The support ribs 3 at the four inner corners of the box body 1 can provide support for the normal stacking of the box body 1, improve the compression resistance of the stacked state of multiple box bodies 1, and reduce the possibility of the box body 1 being deformed.

[0025] As Figure 2 - Figure 4As shown, the side reinforcing rib 2 is in a cross structure, and the side reinforcing rib 2 is fixedly connected to the inner wall of the side of the box body 1. Designing the side reinforcing rib 2 as a cross structure can provide compressive support while reducing material usage and the overall weight of the box body 1. The side reinforcing rib 2 can be made of shape memory alloy, which is convenient for automatically returning to the normal state after the side of the box body 1 is extruded and deformed.

[0026] As Figure 1 - Figure 5 shown, the cross-section of the support rib 3 is L-shaped, and the L-shaped outer wall of the support rib 3 is fixedly connected to the inner wall of the bent part of the box body 1. Designing the support rib 3 as an L shape makes it more fitting with the corners of the box body 1, and while providing support, it reduces the occupation of the internal space of the box body 1.

[0027] As Figure 1 - Figure 3 shown, both the bottom compression block 4 and the top compression block 5 are located inside the four side reinforcing ribs 2 and the four support ribs 3, and are slidably connected to the inner sides of the four side reinforcing ribs 2 and the four support ribs 3. Designing the bottom compression block 4 and the top compression block 5 inside the side reinforcing ribs 2 and the support ribs 3 facilitates the installation of the bottom compression block 4 and the top compression block 5 into the box body 1, making the installation and use more convenient.

[0028] As Figure 1 - Figure 5 shown, both the bottom compression block 4 and the top compression block 5 are foam blocks made of polystyrene. Utilizing the resilience and impact resistance and buffering performance of the foam blocks made of polystyrene can better protect the objects inside the box body 1. At the same time, the cost of using the foam blocks is relatively low, reducing the manufacturing cost.

[0029] As Figure 2 - Figure 4 shown, a placement groove 401 is provided at the central position on the side of the bottom compression block 4 close to the top compression block 5. Providing the placement groove 401 on the bottom compression block 4 makes it difficult for the object to shake after being placed in the placement groove 401, making the packaging more stable.

[0030] As Figure 5 shown, a positioning groove 501 is provided at the central position on the side of the top compression block 5 close to the bottom compression block 4. When covering the object in the box body 1 with the top compression block 5, the positioning groove 501 is stuck on the top of the object, thereby cooperating with the placement groove 401 to fix the position of the object in the box body 1 and prevent the object from shaking and colliding and being damaged in the box body 1.

[0031] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
