[0002] Corrugated box is a common packaging container, mainly made of corrugated cardboard. Corrugated cardboard is a special cardboard made of one or more layers of paper, with high mechanical strength and good cushioning properties. In the manufacturing process, log fiber, hardwood fiber or recycled waste paper is usually used as raw materials, and it is made through screening, crushing, pulping, molding and other steps.

[0003] The production process of corrugated boxes includes die-cutting, creasing, nailing or gluing, etc., and finally forms a three-dimensional carton. Corrugated boxes are widely used in various fields to package various commodities, such as home appliances, electronic products, food and beverages, books, textiles, etc. Its advantages include protecting commodities, facilitating storage and transportation, beautifying commodities and promoting them.

[0011] A further improvement is that a transparent observation plate is provided on the installation tube for conveniently observing the state of the desiccant when the installation tube is taken out from the gap layer.

[0012] A further improvement is that the transparent observation plate is a polycarbonate plate or a polymethyl methacrylate plate.

[0013] A further improvement is that the inner wall of the installation tube is located outside the desiccant and is provided with a heat insulation layer for reducing the heat dissipation to the outside when the desiccant absorbs moisture in the air to generate heat.

[0014] A further improvement is that the heat insulation layer is a polyurethane foam board layer or a polystyrene foam board layer.

[0015] A further improvement is that an opening is provided on the installation tube for pouring the desiccant into or out of the installation tube, and a closing plug is provided on the installation tube in the opening for closing the opening after pouring the desiccant into or out of the installation tube.

DETAILED DESCRIPTION

[0025] The utility model is now further described in conjunction with the accompanying drawings and specific embodiments.

[0026] See also Figures 1 to 4As shown, the technical solution adopted in this specific embodiment is: a moisture-proof corrugated paper box, including two surface layers 1, a corrugated layer 2 arranged between the two surface layers 1, and a plurality of gap layers 3 formed between the corrugated layer 2 and the two surface layers 1, and also including a mounting tube 4 slidably arranged between the surface layer 1 and the corrugated layer 2 and located in the gap layer 3 for being placed in or taken out of the gap layer 3 when driven by an external force, a fixing member arranged on the mounting tube 4 for fixing the mounting tube 4 in the gap layer 3 after the mounting tube 4 is placed in the gap layer 3, a plurality of air inlet holes 5 opened on the mounting tube 4, a plurality of gap holes 6 respectively opened on the two surface layers 1 and connected to the gap layer 3, and a desiccant 7 arranged in the mounting tube 4 for absorbing moisture in the air to prevent the corrugated paper box from getting damp.

[0027] The fixing member includes a plurality of elastic protrusions equidistantly arranged on the mounting tube 4, a plurality of the elastic protrusions are arranged in a ring around the mounting tube 4, and a plurality of the elastic protrusions are arranged along the length direction of the mounting tube 4. The elastic protrusions may also be square protrusions, or an adhesive layer may be directly arranged on the outer surface of the mounting tube 4 without the elastic protrusions 8.

[0028] The elastic protrusion is a rubber protrusion, and the elastic protrusion is an arc protrusion.

[0029] The desiccant 7 is a transparent silica gel desiccant that absorbs moisture in the air and changes color after absorbing moisture. The silica gel desiccant can be selected as a blue desiccant or an orange desiccant. The blue silica gel desiccant will slowly turn into a light red color after absorbing moisture, and the orange silica gel desiccant will turn into a dark green color after absorbing moisture. The transparent silica gel desiccant will turn from transparent to milky white if it only absorbs moisture in the air. The desiccant can also be directly selected from activated carbon particles or limestone particles.

[0030] The installation tube 4 is provided with a transparent observation plate 9 for conveniently observing the state of the desiccant 7 when the installation tube 4 is taken out from the gap layer 3 .

[0031] The transparent observation plate 9 is a polycarbonate plate or a polymethyl methacrylate plate. Both the polycarbonate plate and the polymethyl methacrylate plate are transparent plates, and the polymethyl methacrylate plate is also called an acrylic plate.

[0032] The inner wall of the installation tube 4 is located outside the desiccant 7 and is provided with a heat insulation layer 10 for reducing the heat dissipation when the desiccant 7 absorbs moisture in the air to generate heat.

[0033] The heat insulation layer 10 is a polyurethane foam board layer or a polystyrene foam board layer. Polyurethane rigid foam is a new type of polymer material with low bulk density, low thermal conductivity, high closed cell rate and excellent corrosion resistance. The polystyrene foam board has excellent thermal insulation performance and low thermal conductivity, which can effectively isolate the transfer of cold and hot gases.

[0034] The installation tube 4 is provided with an opening 11 for pouring the desiccant 7 from the installation tube 4 , and the installation tube 4 is provided with a closing plug 12 located inside the opening 11 for closing the opening 11 after pouring the desiccant 7 from the installation tube 4 .

[0035] An elastic sealing ring 13 is disposed on the outer side of the closing plug 12 for improving the sealing performance and friction between the closing plug 12 and the mounting tube 4 after being installed on the mounting tube 4. The elastic sealing ring 13 is a rubber ring.

[0036] The working principle of the utility model is as follows: when the corrugated paper box is placed in a humid environment for a long time, the installation tube 4 is placed in the gap layer 3, and is respectively squeezed with the surface layer 1 and the corrugated layer 2 by a plurality of elastic protrusions 8, so as to increase the friction with the surface layer 1 and the corrugated layer 2, and it is not easy for the installation tube 4 to move naturally in the gap layer 3, and the installation tube 4 can be fixed in the gap layer 3, and humid air can enter the installation tube 4 through the air inlet 5 and the gap hole 6, and the moisture in the air is absorbed by the desiccant 7 to prevent the corrugated paper box from being damp, thereby improving the moisture resistance of the corrugated paper box, and it is not easy to cause the corrugated paper box to be damaged and unable to be used normally; when the installation tube 4 is taken out from the gap layer 3 regularly or at any time, the transparent observation plate 9 can be used to observe the transparent observation plate 9. The state of the transparent silica gel desiccant 7 can be seen. When the color of the transparent silica gel desiccant 7 changes, it is convenient for the user to replace it in time to improve the moisture-proof efficiency. When the desiccant 7 absorbs moisture in the air to generate heat, the heat dissipation is reduced through the heat insulation layer 10. When the mounting tube 4 is taken out from the gap layer 3 and the desiccant 7 needs to be replaced, the closing plug 12 is removed from the mounting tube 4, the desiccant 7 is poured out and replaced, and then the closing plug 12 is installed on the mounting tube 4 to close the opening 11, and the elastic sealing ring 13 is used to improve the sealing and friction between the closing plug 12 and the mounting tube 4, and then the mounting tube 4 is reinstalled. The entire mounting tube 4 can also be replaced after the mounting tube 4 is directly taken out.
