Description

Technical Field

[0001] This utility model relates to the field of paper products technology, specifically a high-strength corrugated paper box. Background Technology

[0002] With the development of the e-commerce industry and the growth of logistics and transportation demand, the selection of packaging materials has become a focus of industry attention. Corrugated paper boxes stand out among many packaging materials due to their outstanding advantages such as low cost, lightweight, easy processing and environmental friendliness, and are widely used in the transportation and storage of various commodities.

[0003] The prior art patent document CN210592913U provides a corrugated paper box that uses a novel corner fixing structure by setting right-angle corner clips. The right-angle crease is used as the positioning center line, and several paper clips and corresponding mounting slots cooperate with each other to fix the right-angle corner clips to the right-angle creases one by one. This makes the corner of the paper box reinforced internally and increases the impact resistance of the corner of the paper box.

[0004] However, the existing technologies still have certain limitations. In actual logistics transportation, corrugated cardboard boxes are subjected to various external forces such as compression and collision. The existing cardboard box structure still has room for improvement in terms of overall strength, making it difficult to effectively resist high-intensity external forces and prone to deformation and damage. At the same time, existing cardboard boxes are also insufficient in terms of handling convenience and stacking stability, and cannot meet the increasingly diversified logistics transportation needs. Therefore, we need a high-strength corrugated cardboard box to improve the overall performance of the cardboard box and better adapt to the development of the logistics industry.

[0023] 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.

[0024] like Figure 1-4As shown, a high-strength corrugated cardboard box includes a box body 1, a box lid 2 with an interference fit to the top of the box body 1, and a fixing component 3 on the outer wall of the box body 1; the box body 1 includes a first corrugated cardboard layer 101, and a first reinforcing core layer 102 is bonded to the outer wall of the first corrugated cardboard layer 101. A first semi-circular protrusion 103 is provided on the outer wall of the first reinforcing core layer 102, and a first cavity 104 is provided on the inner wall of the first reinforcing core layer 102; a second reinforcing core layer 105 is bonded to the outer wall of the first reinforcing core layer 102, and a second semi-circular protrusion 106 is provided on the outer wall of the second reinforcing core layer 105; the inner wall of the second reinforcing core layer 105 has a second semi-circular protrusion 106. The wall is provided with a second recess 107, and the outer wall of the second reinforcing core layer 105 is bonded with a second corrugated paper layer 108, the outer wall of the second corrugated paper layer 108 is bonded with a decorative paper layer 109, and the outer wall of the decorative paper layer 109 is bonded with a waterproof film 110; the fixing component 3 includes a fixing handle 301, and the inner wall of the fixing handle 301 is provided with a threaded hole 302, the inner wall of the threaded hole 302 is threadedly connected with a screw 303, and one end of the screw 303 is fixedly connected with a limiting block 304, the outer wall of the limiting block 304 is rotatably connected with a ring 305, and the outer wall of the ring 305 is fixedly connected with a fixing strap 306.

[0025] Through the above technical solution, the first reinforcing core layer 102 and the second reinforcing core layer 105 form a three-dimensional support network through the interlocking structure of semi-circular protrusions and concave cavities, which greatly enhances the box body 1's resistance to compression and impact. Furthermore, the decorative paper layer 109 enhances the product's aesthetics, meeting the demands of high-end packaging. The outer waterproof film 110 effectively resists erosion from humid environments, extending the box's lifespan. The fixed handle 301 facilitates handling, and the fixed strap 306 allows for easy transport. When box 1 is lifted, the support base 4 effectively protects the fragile corners of box 1, preventing damage to the corners due to collisions during handling and stacking. The positioning block 5 and anti-slip pad 6 structure can lift box 1 as a whole, keeping the bottom of box 1 a certain distance from the ground. This prevents moisture from the ground from seeping into box 1 and increases the friction with the contact surface, improving stability during placement and preventing slippage. The cooperation between the positioning block 5 and the positioning groove 7 allows for precise positioning when multiple boxes are stacked, facilitating the stacking of multiple boxes.

[0026] Specifically, one end of the first semicircular protrusion 103 extends into the second concave cavity 107, and the outer wall of the first semicircular protrusion 103 is bonded to the inner wall of the second concave cavity 107; one end of the second semicircular protrusion 106 extends into the first concave cavity 104, and the outer wall of the second semicircular protrusion 106 is bonded to the inner wall of the first concave cavity 104.

[0027] Through the above technical solution, the first reinforcing core layer 102 and the second reinforcing core layer 105 form a three-dimensional support network through the interlocking structure of semi-circular protrusions and concave cavities, which strengthens the structural strength and effectively improves the box body 1's resistance to compression and impact.

[0028] Specifically, there are two fixed handles 301, and the two fixed handles 301 are symmetrically arranged on the box body 1.

[0029] The above technical solution, with its symmetrically arranged fixed handles 301, makes it easier for one person to use both hands or for two people to move the cardboard box, improving safety and convenience during the handling process.

[0030] Specifically, the fixed handle 301 forms a threaded structure with the screw 303 through the threaded hole 302, and one end of the screw 303 extends into the threaded hole 302 for connection.

[0031] Through the above technical solution, the limiting block 304 is composed of a cylinder and a block. One end of the cylinder is fixed with a screw 303. The ring 305 on the fixing band 306 is assembled on the cylinder of the limiting block 304. The screw 303 is threaded into the threaded hole 302 to complete the installation of the fixing band 306.

[0032] Specifically, a support base 4 is fixedly connected to the bottom of the box body 1, and a positioning block 5 is fixedly connected to the bottom of the support base 4. An anti-slip pad 6 is adhered to the bottom of the positioning block 5. A positioning groove 7 is opened on the top of the box cover 2. There are four support bases 4, and the four support bases 4 are respectively located at the four corners of the lower surface of the box body 1. There are four positioning grooves 7, and two positioning grooves 7 form a group. The two groups of positioning grooves 7 are symmetrically opened on the box cover 2.

[0033] By using the above technical solution, four support seats 4 are set at the four corners of the box body 1, which can effectively protect the corners of the box body 1 and prevent damage to the corners due to collisions during handling and stacking. The inner wall of the positioning groove 7 matches the outer wall of the positioning block 5. When stacked, one end of the positioning block 5 extends into the positioning groove 7, making it less likely for the cardboard box to shake or shift when stacked, thus enhancing stability.

[0034] In use, the lid 2 is first installed on top of the box body 1 via an interference fit, achieving initial assembly of the cardboard box. The first reinforcing core layer 102 and the second reinforcing core layer 105 on the box body 1 form a three-dimensional support network through the interlocking of semi-circular protrusions and concave cavities. When the box body 1 is subjected to external pressure or impact, this three-dimensional structure effectively buffers and resists external forces, preventing deformation or damage to the box body 1, thus protecting the safety of the internal items. The decorative paper layer 109 allows for the selection of different colors and patterns to enhance the box's aesthetics and meet high-end packaging requirements. A waterproof film 110 is bonded to the decorative paper layer 109 to effectively resist humid environments and extend the box's lifespan. When handling the cardboard box, the fixed handle 301 allows for one-handed or two-person handling, improving safety and convenience. If lifting is required... To lift the cardboard box, the fixing strap 306 can be used to lift it. When placing it, the ring 305 can rotate on the limiting block 304, and the fixing strap 306 can be placed on both sides of the box body 1. When the cardboard box is placed on the ground, the combination of the positioning block 5 and the anti-slip pad 6 lifts the box body 1 as a whole, keeping the bottom of the box body 1 a certain distance from the ground. This prevents moisture from the ground from seeping into the box body 1 and increases the friction with the contact surface, improving the stability during placement and preventing slippage. If multiple cardboard boxes need to be stacked, the positioning groove 7 on the box cover 2 and the positioning block 5 on the bottom of the box body 1 cooperate with each other. When stacking, the positioning block 5 accurately extends into the positioning groove 7 to achieve precise positioning of multiple cardboard boxes, preventing the cardboard boxes from shaking or shifting during stacking and ensuring the stability of the stack. This completes all the work. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] 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.
