Description

Technical Field

[0001] The utility model belongs to the technical field of corrugated paper boxes, in particular to a corrugated paper box with a built-in buffer structure composed of corrugated paperboards. Background Art

[0002] Corrugated cardboard, as a multi-layer adhesive, has a core structure that includes at least a layer of corrugated core paper and a layer of solid cardboard. It is the basic material for making corrugated boxes. After fine die-cutting, creasing, nailing or gluing processes, corrugated cardboard can be transformed into a strong and durable corrugated box.

[0003] In current logistics and transportation, in order to ensure the safety of items in cartons, cartons are usually equipped with special buffer structures. However, the buffer structures widely used in the market mainly rely on elastic elements (such as springs, spring sheets, etc.) to achieve the buffering effect. However, this buffering method that relies on elastic elements has a significant disadvantage, that is, its resilience is strong. This strong resilience makes the items in the carton easily float up and down during the buffering process, greatly increasing the risk of damage to the items.

[0004] Therefore, it is very necessary to invent a corrugated paper box with a built-in buffer structure composed of corrugated paperboard. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a corrugated paper box with a built-in buffer structure composed of corrugated paperboard, including a paper box body, a bottom seal, a top seal and a buffer inner lining base, wherein the bottom seal and the top seal are respectively arranged on the upper and lower parts of the paper box body, and the buffer inner lining base is placed on the bottom seal;

[0006] The buffer lining base includes a bottom plate, a socket, a limiting body, a buffer seat, a buffer groove and buffer cotton. The bottom plate is provided with the socket, the limiting body is plugged into the socket provided on the bottom plate, the buffer seat is bonded under the bottom plate, the buffer seat is provided with the buffer groove, and the buffer seat and buffer cotton are placed on the bottom cover.

[0007] Preferably, the bottom plate is a rectangular structure made of corrugated cardboard, the socket provided on the bottom plate is a square socket, and the restricting body is provided with a plug corresponding to the socket.

[0008] Preferably, the buffer seat is a square hollow structure, the buffer grooves are provided in the middle of the four corners of the buffer seat, and at least five buffer seats are provided, which are respectively arranged in the middle and four corners below the bottom plate.

[0009] Preferably, the buffer cotton is located between the buffer seats, the buffer cotton is a rectangular structure, the buffer cotton is located below the bottom plate, the buffer cotton and the bottom plate are not in contact, and there is a distance between them.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] The utility model is different from the traditional method of relying on elastic elements (such as springs, spring sheets, etc.) to achieve the buffering effect. It abandons this traditional method and instead adopts a buffer seat with a unique structure as a buffer mechanism. This buffer seat absorbs external pressure by deformation, thereby achieving the purpose of shock absorption and buffering. Importantly, this design completely abandons the rebound force, thereby effectively avoiding the problem of the up and down floating of the items during transportation caused by the rebound force, greatly improving the safety of the items during transportation and ensuring the safety of the items.

[0019] As attached Figure 1 To Attachment Figure 3 As shown:

[0020] The utility model provides a corrugated paper box with a built-in buffer structure composed of corrugated paperboard, comprising a paper box body 1, a bottom seal 2, a top seal 3 and a buffer inner lining base 4, wherein the bottom seal 2 and the top seal 3 are respectively arranged on the upper and lower parts of the paper box body 1, and the buffer inner lining base 4 is placed on the bottom seal 2.

[0021] The buffer lining base 4 includes a bottom plate 41, a socket 42, a limiting body 43, a buffer seat 44, a buffer groove 45 and a buffer cotton 46. The bottom plate 41 is provided with the socket 42, and the limiting body 43 is plugged into the socket 42 provided on the bottom plate 41. The buffer seat 44 is bonded below the bottom plate 41, and the buffer seat 44 is provided with the buffer groove 45. The buffer seat 44 and the buffer cotton 46 are placed on the bottom cover 2. The buffer lining base 4 abandons the traditional way of relying on elastic elements (such as springs, spring sheets, etc.) to achieve the buffering effect, and instead adopts a buffer seat with a unique structure as a buffer mechanism. This buffer seat 44 absorbs external pressure by deformation, thereby achieving the purpose of shock absorption and buffering. Embodiment 1:

[0022] Specifically, the bottom plate 41 is a rectangular structure made of corrugated cardboard, the socket 42 opened on the bottom plate 41 is a square hole, and the limiting body 43 is provided with a plug corresponding to the socket 42. Through the connection between the plug and the socket 42, the limiting body 43 can be firmly installed on the bottom plate 41 to form an integral structure. The limiting body 43 is not only a simple accessory, but also a component with specific functions. The space formed between the limiting bodies 43 perfectly matches the shape of the items to be protected, and can tightly wrap the items, thereby preventing the items from shaking and moving during transportation.

[0023] Specifically, the buffer seat 44 is a square hollow structure, which not only ensures its sufficient strength, but also allows deformation when subjected to external force, thereby achieving a buffering effect. Buffer grooves 45 are provided in the middle of the four corners of the buffer seat 44. The buffer grooves 45 are the key parts for the buffer seat 44 to achieve deformation and absorb external pressure. In order to provide all-round buffering protection, at least five buffer seats 44 are provided. Among them, one is located at the central position below the bottom plate 41 for main support and buffering, while the remaining four are located at the four corners of the bottom plate 41, respectively, to ensure that when the objects are impacted from different directions, they can be effectively buffered.

[0024] Specifically, the buffer cotton 46 is located between the buffer seats 44, and the buffer cotton 46 can assist the buffer seats 44 in absorbing impact energy, thereby further increasing the buffering effect. At the same time, since the material of the buffer cotton 46 is soft and elastic, it can effectively disperse the impact force and reduce the vibration and impact of the object. In addition, the buffer cotton 46 is placed below the bottom plate 41 and maintains a certain distance from the bottom plate 41. This design not only ensures that the buffer cotton 46 can fully exert its buffering effect, but also avoids direct contact between the buffer cotton 46 and the bottom plate 41, thereby reducing wear and noise caused by friction. Embodiment 2:

[0025] The square hollow structure of the buffer seat 44 allows deformation when subjected to external force while maintaining sufficient strength, thereby absorbing external pressure. The specially designed buffer groove 45 is located in the middle of the four corners of the buffer seat 44, which is the core area for the buffer seat to achieve deformation and absorb impact force. In order to provide all-round buffering protection, the buffer seat 44 is cleverly set at the lower center and four corners of the bottom plate 41 to ensure that the carton can cope with impacts from different directions. The buffer cotton 46, as an auxiliary buffer material, is located between the buffer seats 44. Its soft material and excellent elasticity not only assist the buffer seat 44 in absorbing impact energy, but also effectively disperse the impact force, further reducing the vibration and impact of the items. A certain distance is maintained between the buffer cotton 46 and the bottom plate 41 to avoid wear and noise that may be caused by direct contact. When the carton is subjected to external impact, this innovative combined buffer mechanism immediately takes effect. First, the buffer grooves 45 in the middle of the four corners of the buffer seat 44 are deformed to absorb part of the impact force; then, the soft material of the buffer cotton 46 quickly disperses and absorbs the remaining impact force. This double cushioning design greatly reduces the vibration and impact on items during transportation, thus ensuring the safety of the items.

[0026] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
