Description

Technical Field

[0001] This utility model relates to the field of cardboard box manufacturing technology, specifically to a cushioned cardboard box with an anti-crushing structure. Background Technology

[0002] During the transportation and storage of goods, cardboard boxes, as commonly used packaging containers, are often subjected to compression from various directions. Traditional cardboard boxes have a simple structure, and when subjected to significant external pressure, the contents inside are easily damaged, leading to economic losses.

[0003] However, in actual use, some existing cushioning cartons, although they have increased the cushioning structure to a certain extent, have limited cushioning effect, and the cushioning structure is complicated to install and costly, making it difficult to be widely used. Therefore, there is an urgent need for a cushioning carton with an efficient anti-crushing structure. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a cushioning carton with an anti-crushing structure to solve the problems mentioned in the background art, such as limited cushioning effect, complex installation of cushioning structure, high cost, and difficulty in widespread application.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A cushioning carton with an anti-crushing structure includes a carton body, which is composed of four side panels, a cover plate and a bottom plate. The four side panels are respectively perpendicularly connected to the bottom plate, and the cover plate is openable and closable above the four side panels.

[0007] The side panel includes an outer paperboard and an inner paperboard, with a honeycomb-shaped buffer layer between the outer paperboard and the inner paperboard;

[0008] The four corners of the enclosure are equipped with right-angled reinforcing corner protectors, with the inner side of the reinforcing corner protectors closely fitted to the side panels and the outer side protruding from the side panels.

[0009] The lower surface of the cover plate and the upper surface of the bottom plate are both provided with corrugated buffer pads. The corrugated buffer pads are made of elastic material, and the crests and troughs of the corrugated buffer pads are fixedly connected to the cover plate and the bottom plate, respectively.

[0010] The inner surface of the inner cardboard has several hemispherical elastic protrusions evenly distributed, and the elastic protrusions are integrally formed with the inner cardboard.

[0011] By adopting the above technical solution, and through a multi-layered buffer and reinforcement structure, all-round anti-squeezing is achieved, effectively protecting the items inside the box.

[0012] Preferably, the outer surfaces of the four side panels are covered with a layer of star-shaped cardboard, and the star-shaped cardboard is tightly bonded to the outer cardboard with adhesive.

[0013] By adopting the above technical solution, the star-shaped cardboard is made of high-strength corrugated cardboard with a thickness of 2-3mm.

[0014] Preferably, the honeycomb-shaped buffer layer has regular hexagonal honeycomb pores with a side length of 5-10 mm.

[0015] By adopting the above technical solution and setting appropriately sized regular hexagonal honeycomb holes, it is possible to reasonably control material costs and carton weight while ensuring cushioning effect.

[0016] Preferably, the reinforcing corner protectors are made of hard plastic with a thickness of 3-5mm.

[0017] By adopting the above technical solutions, the reinforced corner protectors made of rigid plastic have good strength and durability. The appropriate thickness can provide sufficient support without increasing the cost of the cardboard box too much.

[0018] Preferably, the wave height of the corrugated buffer pad is 10-15mm and the wavelength is 20-30mm.

[0019] By adopting the above technical solution, this size design enables the corrugated cushioning pad to effectively absorb and disperse external forces when compressed, thereby enhancing the cushioning effect.

[0020] Preferably, the radius of the elastic protrusion is 3-5 mm, and the distance between two adjacent elastic protrusions is 10-15 mm.

[0021] By adopting the above technical solution, the reasonable size and spacing of the elastic protrusions can form an effective buffer space between the items inside the box and the inner cardboard, protecting the items from being squeezed.

[0022] In summary, the present invention has the following main advantages:

[0023] The newly added star-shaped cardboard structure can significantly enhance the compressive strength of the side panels. The star-shaped layout can distribute the squeezing force from the sides to all directions, and the high-strength corrugated cardboard material ensures the structural strength.

[0024] By incorporating a honeycomb-shaped buffer layer, a wavy buffer pad, and hemispherical elastic protrusions, multiple layers of buffer protection are formed, which can effectively absorb and disperse external forces from multiple directions, greatly improving the cardboard box's anti-crushing ability and better protecting the items inside.

[0031] 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.

[0032] refer to Figure 1 , Figure 2 and Figure 4 A cushioning carton with an anti-crushing structure includes a carton body (1), characterized in that: the carton body 1 is composed of four side panels 11, a cover plate 12 and a bottom plate 13, the four side panels 11 are respectively vertically connected to the bottom plate 13, and the cover plate 12 is openably and closably disposed above the four side panels 11.

[0033] The side panel 11 includes an outer paperboard 111 and an inner paperboard 112, with a honeycomb-shaped buffer layer 113 disposed between the outer paperboard 111 and the inner paperboard 112;

[0034] Right-angle reinforced corner guards 2 are provided at all four corners of the box body 1. The inner side of the reinforced corner guards 2 is tightly fitted with the side panel 11, and the outer side protrudes from the side panel.

[0035] The lower surface of the cover plate 12 and the upper surface of the base plate 13 are both provided with a corrugated buffer pad 4. The corrugated buffer pad 4 is made of elastic material, and the crests and troughs of the corrugated buffer pad 4 are fixedly connected to the cover plate 12 and the base plate 13 respectively.

[0036] The inner surface of the inner cardboard 112 is evenly distributed with several hemispherical elastic protrusions 114, and the elastic protrusions 114 are integrally formed with the inner cardboard 112.

[0037] Through a multi-layered cushioning and reinforcement structure, it achieves all-round anti-squeezing and effectively protects the items inside the box.

[0038] refer to Figure 2 The outer surfaces of the four side panels 11 are covered with a layer of cross-shaped cardboard 3, and the cross-shaped cardboard 3 is tightly bonded to the outer cardboard 112 with glue.

[0039] The star-shaped cardboard is made of high-strength corrugated cardboard with a thickness of 2-3mm.

[0040] refer to Figure 3 , Figure 4 and Figure 5 The honeycomb buffer layer 113 has regular hexagonal honeycomb holes with a side length of 5-10mm. The reinforcing corner protectors 2 are made of hard plastic with a thickness of 3-5mm. The wave height of the wavy buffer pad 4 is 10-15mm and the wavelength is 20-30mm. The radius of the elastic protrusions 114 is 3-5mm and the distance between two adjacent elastic protrusions is 10-15mm.

[0041] By setting appropriately sized hexagonal honeycomb holes, material costs and carton weight can be reasonably controlled while ensuring cushioning effect. The reinforced corner protectors made of rigid plastic have good strength and durability. The appropriate thickness can provide sufficient support without increasing the cost of the carton too much. The size design of the wavy cushioning pad can effectively absorb and disperse external force when squeezed, enhancing the cushioning effect. In addition, the reasonable size and spacing of the elastic protrusions can form an effective cushioning space between the items inside the box and the inner cardboard, protecting the items from being squeezed.

[0042] Because the bottom plate has a corrugated cushioning pad, it can provide initial cushioning protection for the items. The corrugated cushioning pad on the underside of the cover plate can also provide cushioning protection for the items above. During transportation and storage, when the carton is squeezed from the sides, the star-shaped cardboard first disperses some of the pressure. The material around the circular reinforcing holes undergoes slight deformation to assist in cushioning. Subsequently, the honeycomb cushioning layer in the side plate absorbs and disperses the remaining external force. At the same time, the elastic protrusions on the inner side of the inner cardboard can further cushion the pressure on the items. When squeezed or collided from the corners, the reinforced corner protectors can effectively resist external forces and protect the items inside the carton.

[0043] Working principle: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, when assembling the cushioning carton of this utility model, firstly, the bottom of the four side panels is vertically fixed to the bottom panel by glue or nails to form the side and bottom structure of the carton; then, the reinforcing corner protectors are installed at the four corners of the carton, and the inner side of the reinforcing corner protectors is tightly attached to the side panels with glue to ensure a firm installation; then, the corrugated cushioning pads are pasted to the upper surface of the bottom panel and the lower surface of the cover plate, so that the crests and troughs are fixed to the bottom panel and the cover plate; then, the star-shaped cardboard is pasted to the outer surface of the four side panels with glue; finally, the cover plate is set on top of the four side panels in an openable manner to complete the assembly of the carton.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
