[0031] It should be noted that the carton body 1 and the box cover 2 are connected by a magnetic sealing strip or a self-adhesive sealing tape to improve the sealing performance and facilitate user operation.

[0032] See also Figure 3In order to improve the moisture-proof performance of the carton body 1, the moisture-proof mechanism 3 in this embodiment includes a moisture-proof layer 31, a heat-insulating layer 32, a support plate 33, and a desiccant 34. The moisture-proof layer 31 is fixed to the inner wall of the carton body 1 and is used to prevent water vapor from penetrating the carton body 1. The moisture-proof layer 31 is made of a metal film. The metal film can effectively prevent the penetration of water vapor, prevent moisture from invading the inner cavity of the carton body 1, and can block moisture, effectively protecting the internal newspapers from being affected by moisture. The heat-insulating layer 32 is fixed to the inner side of the moisture-proof layer 31 and is used to reduce the impact of external temperature fluctuations on the carton body 1. In order to avoid the influence of the internal environment, foam plastic or bubble film is used as the insulation layer 32 to reduce the condensation phenomenon caused by temperature difference and keep the carton body 1 in a dry environment. The support plate 33 is fixed to the bottom between the four inner walls of the carton body 1. A through hole 35 is provided on the upper surface of the support plate 33. The desiccant 34 is placed on the inner bottom wall of the carton body 1 and is used to adsorb moisture in the carton body 1. The desiccant 34 is silica gel or mineral desiccant 34, which can adsorb excess moisture in the air of the carton body 1 through the through holes 35 provided on the upper surface of the support plate 33.

[0034] Among them, a fixing hole is opened on the front of the carton body 1, and sliding strips are fixed on the front of the carton body 1 and on the upper and lower sides of the fixing hole. The inner cavities of the two sliding strips are slidably connected with a sealing plate, and the size of the sealing plate is larger than the size of the inner cavity of the fixing hole.

[0035] In addition, when the desiccant 34 needs to be replaced, first pull the sealing plate to the left so that the top and bottom of the sealing plate slide in the inner cavity of the slide bar until the desiccant 34 can be taken out from the inner cavity of the fixing hole and replaced.

At this time, the inner cavity of the carton body 1 is connected to the external air through the vent 4, avoiding the problem of excessive internal humidity due to closure.

[0039] The working principle of the above embodiment is:

[0040] (1) The moisture-proof layer 31 is made of a metal film, which can effectively prevent the penetration of water vapor and prevent moisture from invading the inner cavity of the carton body 1. It can block moisture and effectively protect the newspapers and periodicals inside from being affected by moisture. Foam plastic or bubble film is used as the heat insulation layer 32, which can reduce the impact of external temperature fluctuations on the environment inside the carton body 1, reduce the condensation phenomenon caused by temperature difference, and keep the carton body 1 in a dry environment. The desiccant 34 is a silica gel or mineral desiccant 34, which can absorb excess moisture in the air of the carton body 1 through the through hole 35 opened on the upper surface of the support plate 33. When the desiccant 34 needs to be replaced, first pull the sealing plate to the left so that the top and bottom of the sealing plate slide in the inner cavity of the slide until the desiccant 34 can be taken out from the inner cavity of the fixed hole and replaced.

[0041] (2) When the ventilation mechanism 5 needs to be used, first rotate the screw sleeve 56 to move the screw sleeve 56 to the outer surface of one of the threaded rods 55, and then move the two moving rods 53 in opposite directions. The movement of the two moving rods 53 drives the two moving plates 52 to move in opposite directions. At this time, the two moving plates 52 are separated, and the two moving plates 52 can enter the inner cavity of the installation groove 57 through the guidance of the limit plate 54. At this time, the inner cavity of the carton body 1 is connected to the external air through the vent 4, avoiding the problem of excessive internal humidity due to closure.
