Description

Technical Field

[0001] The utility model relates to the technical field of paper boxes, in particular to a multi-layer paper box with anti-deformation function. Background Technique

[0002] With the enhancement of environmental awareness and the limitation of resources, packaging materials tend to use recyclable or biodegradable materials. As an environmentally friendly packaging material, paper boxes are widely used because of their light weight, recyclability and high cost-effectiveness. A paper box is a three-dimensional shape, which is composed of a polyhedron formed by the movement, stacking, folding and surrounding of several faces. Traditional single-layer paper boxes may be easily deformed or damaged during transportation and storage, affecting their ability to protect the contents. Therefore, the design of multi-layer paper boxes came into being, and the anti-deformation ability was improved by increasing the number of layers and the internal support structure.

[0003] The Chinese patent document with the authorization publication number of CN215399946U discloses a paper box with multi-layer protection effect, including a paper box main body. An inlay box is installed inside the paper box main body. A foam cladding is arranged at the connection between the inlay box and the inner wall of the paper box main body. A protective support backing plate is installed at the bottom of the inlay box. The inside of the protective support backing plate is jointly composed of cardboard, a rubber cushion layer and a foam cushion plate. The cardboard is located on the upper surface of the rubber cushion layer, and the foam cushion plate is located on the lower surface of the rubber cushion layer. A fixed bottom plate is installed at the bottom of the paper box main body. A support buffer protection cushion block is installed between the protective support backing plate and the fixed bottom plate. The upper and lower ends of the support buffer protection cushion block are fixed to the surfaces of the protective support backing plate and the fixed bottom plate respectively through rubber cushion blocks, and buffer springs are installed on the surface of the support buffer protection cushion block. Through the buffer protection design inside the paper box, the impact damage caused by the paper box falling to the inlay box can be effectively reduced, so as to provide good protection for the internal items.

[0004] In the prior art, although the design of multi-layer paper boxes has improved the anti-deformation ability and protection effect of packaging to a certain extent, there are still some deficiencies and problems: First, the structural stability of multi-layer paper boxes is poor, especially when subjected to external force impact, it is easy to cause deformation or damage to the overall structure; Second, in order to improve the anti-deformation ability, multi-layer paper boxes may increase additional layers and support structures, which will lead to an increase in the overall weight, thus affecting the transportation cost and efficiency.

[0023] As Figures 1 to 4In an embodiment of the anti-deformation multi-layer paper box of the present utility model shown, the anti-deformation multi-layer paper box of this embodiment includes a paper box body 1 and a box cover 2. Both the paper box body 1 and the box cover 2 are composed of an outer composite facing paper, a waterproof film, and an inner composite facing paper. A groove 101 is provided on the inner side wall of the paper box body 1, and a spacer 100 is inserted on the groove 101. Frame boxes 3 are provided at the four corners inside the paper box body 1. The inside of the frame box 3 is provided with a cavity, and the top of the frame box 3 is open. A support assembly 4 is provided inside the frame box 3; the support assembly 4 includes a support column 41, a support rod 42, and a support plate 43. The support plate 43 abuts against the inner side wall of the frame box 3, and anti-slip lines are provided on the side surface of the support plate 43; a slot 5 is provided on one side of the bottom of the frame box 3, and a base 6 is inserted on the slot 5. The bottom of the support column 41 is fixedly connected to the base 6; a clamping block 7 is fixedly connected to the bottom of the box cover 2, and the box cover 2 is fixed on the paper box body 1 through the clamping block 7; inner grooves 8 are provided on the diagonal line of the bottom of the paper box body 1, and a wire 9 is embedded and fixed on the inner grooves 8. The upper end of the wire 9 is on the same horizontal plane as the inner bottom wall of the paper box body 1. In the present utility model, first, the spacer 100 is inserted on the groove 101 on the inner side wall of the paper box body 1, which not only meets the layering requirements but also increases the internal support of the paper box, reducing the possibility of deformation. At the same time, frame boxes 3 are provided at the four corners inside the paper box body 1. Through the cavity structure inside the frame box 3 and the setting of the support assembly 4, the support plate 43 in the support assembly 4 abuts tightly against the inner side wall of the frame box 3 to provide a better support effect, further enhancing the stability and anti-deformation ability of the paper box. And the slot 5 at the bottom of the frame box 3 and the inserted base 6 enable the bottom of the support column 41 to be fixedly connected to the base 6, forming a stable support structure and enhancing the load-bearing capacity and anti-deformation property of the paper box; secondly, inner grooves 8 and the embedded and fixed wire 9 are provided on the diagonal line of the bottom of the paper box body 1, increasing the strength and anti-deformation ability of the bottom of the paper box. At the same time, the elasticity of the wire 9 also helps to buffer external impacts.

[0024] In an embodiment of the present application, preferably, both ends of the spacer 100 are provided in a set with the groove 101. The number of the spacers 100 is more than three. More than three spacers 100 are arranged at equal distances inside the paper box body 1. In the present utility model, both ends of the spacer 100 are provided in a set with the groove 101 to ensure that the spacer 100 maintains the correct position and direction inside the paper box; more than three spacers 100 are arranged at equal distances inside the paper box body 1. This evenly distributed setting helps to balance the internal pressure and reduce local stress concentration, thereby reducing the risk of deformation of the paper box during loading and transportation. At the same time, the setting of the spacer 100 enhances the internal structural strength of the paper box body 1. Especially when bearing vertical pressure or impact, the spacer can disperse the force and reduce the direct impact on the paper box body.

[0025] In an embodiment of the present application, preferably, a card slot 21 is provided on the inner side wall of the upper end of the frame box 3, and an insertion bar 71 is provided on the side surface of the clamping block 7.

The support rod 42 is welded to the support column 41, and the support rod 42 and the support column 41 are arranged perpendicularly. One end of the support rod 42 away from the support column 41 is fixedly connected to a support plate 43. In the present utility model, the height of the support column 41 is adapted to the height of the frame box 3, ensuring that the support system can completely fill the internal space of the frame box 3 and provide uniform support force; the support rod 42 and the support column 41 are arranged perpendicularly, and this design helps to form a stable structure inside the frame box 3, increasing the overall stability and load-bearing capacity. At the same time, the support rod 42 is welded to the support column 41, providing a firm connection method to ensure that there is no relative movement or detachment under force. One end of the support rod 42 away from the support column 41 is fixedly connected to a support plate 43. The support plate 43 can provide an additional support area, enhancing the load-bearing capacity and anti-deformation ability of the frame box 3. And the support plate 43 abuts against the inner side wall of the frame box 3, helping to evenly distribute the force, reducing local stress concentration, and improving the durability of the paper box. In addition, anti-slip patterns are provided on the side surface of the support plate 43, which helps to increase the friction with the inner side wall of the frame box 3 and prevent the support plate from sliding.
