Description

Technical Field

[0001] The utility model relates to the technical field of packaging cartons, and specifically relates to a three-dimensional tempered high-support carton. Background Art

[0002] Cartons are the most widely used packaging products and the preferred packaging materials for various commodities. Due to their low price, convenient production, light texture, recyclability and other characteristics, cartons have always occupied the leading position in the packaging market. However, cartons also have their own limitations. For example, cartons are prone to water absorption damage, heat intolerance, pressure intolerance and other disadvantages, which have always restricted their development. Especially the disadvantage of pressure intolerance. During the packaging and transportation process, the carton body is prone to breakage due to extrusion, thus damaging the commodities inside. In the prior art, such as a heavy-duty compressive carton of the applicant, the publication number CN220577744U realizes higher compressive performance of the carton by setting a compressive frame between the outer box and the inner box, and the outer box, the inner box and the compressive frame are all fixedly arranged on the bottom plate. We found in production practice that the production process of such a carton is more, which will increase the production cost. In addition, since the support plate is made of a plastic material with toughness, introducing plastic into the carton will further increase the production cost, which is not conducive to cost reduction and efficiency improvement. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a three-dimensional tempered high-support carton, which can reduce the production cost without reducing the compressive performance of the carton.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A three-dimensional tempered high-support carton, including a box cover, a box body, a support frame and a bottom plate. The box body and the support frame are both fixedly arranged on the bottom plate. Among them, the box cover covers the box body, and the inner wall of the box cover is in seamless contact with the outer circumference of the box body. The support frame is sleeved on the outer circumference of the box body and under the box cover, and the box cover is press-connected with the support frame. The support frame is in a square tube structure and its outer wall is in a hollowed-out shape.

[0005] Preferably, the inner wall of the support frame is in seamless contact with the outer wall of the box body.

[0006] Preferably, the support frame is composed of an upper frame, a lower frame and a plurality of support rods. The plurality of support rods are arranged between the upper frame and the lower frame. The lower frame is fixedly connected with the bottom plate. The upper frame is press-connected with the box cover.

[0007] Preferably, the upper frame, the lower frame and the support rods are all of a hollow structure.

[0008] Preferably, the upper frame, the lower frame and the support rods are all bonded to the box body.

[0009] Preferably, the top wall of the box cover is located above the box body.

[0010] Preferably, the box cover, the box body, the support frame and the bottom plate are all made of corrugated cardboard.

[0011] Preferably, the wall thickness of the outer wall of the box cover is greater than that of the box body.

[0012] Preferably, a plurality of grooves are formed in the box cover.

[0013] Preferably, the opening direction of the groove is perpendicular to the main plane of the top wall of the box cover.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows: by arranging a support frame with an integral structure on the outer periphery of the box body, the support frame is in a square and hollow cylindrical structure. After the box cover is covered on the box body, the box cover is crimped with the support frame and the inner top wall of the box cover does not contact the box body, so that the cardboard box not only has good compressive performance but also has a simpler structure, reducing the production cost of the cardboard box.

[0018] The following further describes in detail the specific embodiments of the present utility model to enable those skilled in the art to better understand how to practice the present utility model. Although the present utility model is described in conjunction with its preferred specific embodiments, these embodiments are only illustrative and do not limit the scope of the present utility model.

[0019] Specific Embodiment 1: Please refer to Figure 1-2A three-dimensional toughened high-support carton includes: a box cover 1, a box body 2, a support frame 3 and a bottom plate 4, wherein the box body 2 and the support frame 3 are fixedly arranged on the bottom plate 4, wherein the support frame 3 is sleeved on the outer periphery of the box body 2 and the support frame 3 is in surface contact with the outer wall of the box body 2, or the box body 2 is located on the inner side of the support frame 3, and the support frame 3 provides peripheral support, so that the box body 2 can carry more articles and is not easy to collapse, and at the same time, the support frame 3 can also form a layer of protection on the outer periphery of the box body 2 to reduce the deformation of the box body 2 due to the squeezing of external articles; in addition, the box cover 1 is arranged on the box body 2, specifically, When the box cover 1 is covered on the box body 2, there is seamless contact between the inner wall of the box cover 1 and the outer wall of the box body 2. The advantage of such a design is that it can prevent air from entering to the greatest extent and achieve the purpose of moisture-proof. At the same time, the lower end of the box cover 1 is crimped with the support frame 3, and the upper end of the box body 2 does not contact the top wall of the box cover 1. When the carton is subjected to force in the longitudinal direction, the force exerted on the box cover 1 will be directly transmitted to the support frame 3 and the bottom plate 4, and will not be directly applied to the box body 2, thereby maximizing the compressive resistance of the main load-bearing part of the carton, that is, the box body 2, so that the carton has high support and high pressure resistance.

[0020] In the present embodiment, the support frame 3 is a square cylindrical structure as a whole, and its body is hollow. This can reduce the deadweight of the support frame 3, and thus reduce the deadweight of the carton. On the other hand, the hollow body can also reduce the material consumption of the support frame 3 and reduce the production cost. Specifically, the support frame 3 includes an upper frame 31, a support rod 32 and a lower frame 33. The upper frame 31 and the lower frame 33 have the same structure and are both "mouth"-shaped. A plurality of support rods 32 are provided, and the plurality of support rods are evenly distributed between the upper frame 31 and the lower frame 33.

[0021] For the stability of the structure, during the production, the box body 2 needs to be fixed on the bottom plate 4 first, and then the support frame 3 is sleeved on the outside of the box body 2, and glue is applied to the contact points between the support frame 3, the box body 2 and the bottom plate 4 to make the support frame 3, the box body 2 and the bottom plate 4 firmly adhered. In this way, the production process of the carton can be simplified and the production cost can be reduced.

[0022] In a preferred embodiment, the upper frame 31, the support rod 32 and the lower frame 33 are all hollow structures, which can not only improve the compression resistance of the support frame 3 itself, but also reduce its own weight and reduce material consumption.

[0023] In this embodiment, the outer wall thickness of the box cover 1 is greater than the wall thickness of the box body 2. A plurality of evenly distributed grooves 11 are longitudinally opened on the outer wall of the box cover 1. The arrangement of the grooves 11 can facilitate lifting the box cover 1 and reduce the weight of the box cover 1.

[0024] Furthermore, the box cover 1, the box body 2, the support frame 3 and the bottom plate 4 are all made of corrugated cardboard.

[0025] Through this technical solution, by arranging a support frame with an integral structure on the outer periphery of the box body, the support frame is in the shape of a square and hollow cylindrical structure. After the box cover is covered on the box body, the box cover is crimped with the support frame and the inner top wall of the box cover does not contact the box body, making this carton not only have good compressive performance but also make the structure of this carton simpler, reducing the production cost of the carton.

[0026] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
