Description

Technical Field

[0001] This utility model relates to the field of paper product packaging box technology, specifically a moisture-proof paper product packaging box. Background Art

[0002] Cardboard box packaging refers to the packaging of products in paper boxes during the circulation process to protect the products, facilitate storage and transportation, and promote sales. Cardboard box packaging is the most widely used packaging method. It is different from wooden box packaging, woven bag packaging, cloth bag packaging, and plastic box packaging. Cardboard box packaging has the characteristics of easy material sourcing, light weight, easy printing, easy design and molding, and low cost. In the packaging industry, paper products are widely used due to their recyclability, low cost, and environmental friendliness. However, paper products are easily damaged in humid environments, especially during sea transportation and storage. Cardboard boxes become weaker and more prone to breakage after getting damp, which not only affects the quality of the product but also increases transportation costs.

[0003] Existing paper product packaging boxes generally have a simple structure. When removing items from the bottom of the box, it is inconvenient because the items are deep and the light is dim.

[0004] Existing technology (publication number CN217321434U) discloses a moisture-proof paper product packaging box. This technical solution involves simultaneously pulling down the lifting parts on both sides. Driven by the pull rope, the lifting parts move the lifting plate inside the packaging box upward. When the lifting parts move to the corresponding position of the limiting part, the limiting part restricts the lifting parts, thereby fixing the lifting plate to the top of the packaging box. The upward movement of the lifting plate moves the items at the bottom of the packaging box upward, making it easier to remove the items from the bottom of the packaging box. However, existing paper product packaging boxes cannot completely solve the problem of moisture absorption, because water can penetrate into the cardboard box through the fiber gaps, causing the cardboard box to soften, deform, or even rot. At the same time, these treatment methods increase the cost of the cardboard box and reduce its market competitiveness. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a moisture-proof paper product packaging box, including a box body, a cover plate provided on the upper surface of the box body, a microporous membrane provided on the inner wall of the box body, a drainage groove provided at the bottom edge of the inner side of the box body, and water outlet holes provided on the left and right sides below the front and back sides of the box body, as well as at the two corners below the left and right sides of the left and right sides of the box body.

[0009] Preferably, grooves are provided in the upper center of both the left and right sides of the box.

[0010] Two grooves run through the upper center of the left and right sides of the box, making it convenient for staff to pick up the box.

[0011] Preferably, the front and back of the housing are provided with a number of protruding rods.

[0012] The protruding bars can increase the load-bearing capacity of the cardboard box, making it more sturdy and durable.

[0013] Preferably, the bottom of the box has a placement slot.

[0014] Preferably, a pressure plate is provided above the placement slot.

[0015] The placement slot is fitted into the bottom of the box and is used to place the desiccant. It can absorb the moisture inside the carton and keep the carton dry. The pressure plate can cover the upper surface of the placement slot and has a certain degree of ventilation, pressing down the desiccant while ensuring the flatness of the bottom of the box.

[0016] Compared with the prior art, this utility model provides a moisture-proof paper product packaging box, which has the following beneficial effects:

[0017] 1. This utility model utilizes a microporous membrane installed on the inner wall of the box. The microporous membrane is made of polyethylene material and is breathable. Water vapor can pass through the inner wall of the carton, but water droplets cannot penetrate in. The drainage channel is embedded in the bottom edge of the box. Water on the surface of the microporous membrane falls into the drainage channel and is discharged outward through the drainage hole, thereby effectively improving the moisture-proof effect of the packaging box.

[0018] 2. This utility model utilizes a placement groove at the bottom of the cardboard box to hold a desiccant, which absorbs moisture inside the box and keeps it dry, thereby increasing the dryness of the cardboard box. Attached Figure Description

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Please see Figure 1-3 A moisture-proof paper product packaging box includes a box body 1, a cover plate 101 on the upper surface of the box body 1, a microporous membrane 2 on the inner wall of the box body 1, a drainage groove 3 at the bottom edge of the inner side of the box body 1, and water outlet holes 4 at the lower left and right sides of the front and back of the box body 1, as well as at the two lower corners of the left and right sides of the box body 1. The cover plate 101 seals the inside of the box body 1. The microporous membrane 2 is made of polyethylene material and is breathable. Due to the presence of the microporous membrane 2, water vapor can pass through the inner wall of the box body 1, but water droplets cannot penetrate in, thus effectively preventing the box body 1 from getting damp. The drainage groove 3 is embedded in the bottom edge of the inner side of the box body 1. Water droplets attached to the surface of the microporous membrane 2 fall into the drainage groove 3 along the inner wall of the box body 1 and are discharged outward through the water outlet holes 4, avoiding water from affecting the box body 1 for a long time.

[0025] Specifically, such as Figure 1 As shown, grooves 102 are provided in the upper center of both the left and right sides of the box 1.

[0026] With the above technical solution, two grooves 102 are respectively inserted through the upper middle part of the left and right sides of the box 1, making it convenient for staff to take the box 1.

[0027] Specifically, such as Figure 1 As shown, the front and back of the box 1 are provided with a number of protruding rods 103.

[0028] Through the above technical solution, the protruding rod 103 can increase the load-bearing capacity of the carton, making the carton more sturdy and durable.

[0029] Specifically, such as Figure 2 and Figure 3 As shown, a placement groove 5 is provided at the bottom of the interior of the box 1, and a pressure plate 6 is provided above the placement groove 5.

[0030] Through the above technical solution, the placement groove 5 is fitted into the bottom of the box body 1 to place the desiccant, which can absorb the moisture inside the carton and keep the carton dry. The pressure plate 6 can cover the upper surface of the placement groove 5 and has a certain ventilation effect, which can press down the desiccant while ensuring the flatness of the bottom of the box body 1.

[0031] When in use, the staff places the dehumidifier in the placement slot 5 at the bottom of the box 1, covers the inside of the placement slot 5 with the pressure plate 6 to cover the dehumidifier, and places the items inside the box 1. When water seeps into the inside of the box 1, the water slides down through the microporous membrane 2 and falls into the drainage slot 3, and is discharged out through the water outlet 4.

[0032] 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.
