Description

Technical Field

[0001] This utility model relates to the field of packaging technology, and more specifically, to a moisture-proof logistics cardboard box. Background Technology

[0002] Cardboard packaging is an indispensable part of modern logistics, serving to load and protect goods.

[0003] Chinese utility model patent CN217673805U describes an environmentally friendly and breathable cardboard box, belonging to the field of cardboard box technology. It includes a filter element and a connected box body and box lid. The box body has an installation port. The filter element includes a connecting ring and a filter plate that abut against each other. The connecting ring passes through the box body through the installation port and abuts against the box body. The connecting ring is formed with a sliding track that is movably connected to the filter plate. The opening of the sliding track faces the box lid. The box body is detachably connected to a connector that is connected to the filter plate.

[0004] However, the existing solutions still have shortcomings: the air exchange rate of the vents is fixed and cannot be flexibly adjusted according to the type, quantity, ripeness of the fruit inside the box, and changes in the transportation environment. If the air exchange is too slow, moisture and carbon dioxide accumulate too quickly inside the box; if the air exchange is too fast, the fruit is prone to moisture loss. In addition, this type of detachable structure has many components, making assembly complex, and the filter needs to be fixed to the cardboard box body with connectors, increasing manufacturing processes and costs.

[0005] Therefore, this utility model provides a moisture-proof logistics cardboard box, which aims to solve the technical problem of how to simplify the structure, achieve adjustable ventilation speed of the cardboard box, and take into account the requirements of moisture-proof, insect-proof, and dust-proof. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a moisture-proof logistics cardboard box.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0008] A moisture-proof logistics cardboard box includes a box body and a box lid. The side wall of the box body has a ventilation port. A shielding plate is provided on the box body at the ventilation port. The edge of the shielding plate is glued to the box body. The shielding plate is used to block the ventilation port. A flow channel is formed between the shielding plate and the box body. An easy-tear part is formed on the shielding plate at the ventilation port.

[0009] The present invention is further configured such that: the shielding sheet includes a connecting layer, a surface layer and a filter layer, the connecting layer and the filter layer are both located on the side of the surface layer facing the box body, the tear-off part corresponds to the connecting layer, and the filter layer corresponds to the air exchange port.

[0010] The present invention is further configured such that the connecting layer is cut from corrugated cardboard material.

[0011] The present invention is further configured such that: the two ends of the shielding sheet corresponding to the easy-tear portion have protrusions protruding from the surface of the shielding sheet.

[0012] The present invention is further configured such that: a plurality of easy-tear portions are provided, and the plurality of easy-tear portions are spaced apart.

[0013] The present invention is further configured such that the filter layer is made of sponge material.

[0014] In summary, this utility model has the following beneficial effects:

[0015] It is necessary to increase the air exchange rate inside the cardboard box. This can be achieved by increasing the number of tearable sections, which increases the speed at which air passes through the filter layer and air vents, ensuring that the air exchange rate of the cardboard box is adapted to the needs of the fruit inside.

[0016] When air circulates, it is filtered by the filter layer, which prevents mosquitoes and dust from entering the cardboard box and ensures the protection of the fruit. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1 , Figure 2 as well as Figure 3 As shown, this application provides a moisture-proof logistics cardboard box, including a box body 1 and a box lid 2. When fruit is placed inside the box body 1, the opening of the box body 1 can be covered by the box lid 2, thereby forming a shield and protection for the items. The side wall of the box body 1 is provided with a ventilation port 3, and the air inside the cardboard box can exchange gases with the outside through the ventilation port 3, reducing the increase in temperature, humidity and carbon dioxide content inside the cardboard box body 1 caused by respiration, thus slowing down the spoilage rate of the fruit.

[0023] like Figure 1 , Figure 2 as well as Figure 3 As shown, the box 1 is equipped with a shielding sheet, which includes a connecting layer 4, a surface layer 5, and a filter layer 6. The connecting layer 4 and the filter layer 6 are both located on the side of the surface layer 5 facing the box 1. In this embodiment, the connecting layer 4 is arranged in a ring structure, and the filter layer 6 is located at the center of the ring structure of the connecting layer 4. The edge of the connecting layer 4 is bonded to the box 1 with an adhesive to achieve the connection between the shielding sheet and the box 1. The filter layer 6 corresponds to the air vent 3. The filter layer 6 is made of sponge material, while the connecting layer 4 is cut from corrugated cardboard material. The corrugated cardboard can absorb some of the moisture inside the box, which can increase the moisture-proof effect. At the same time, the corrugated cardboard supports the shielding sheet and the box 1 to form a flow channel. Outside air can flow through the flow channel, pass through the filter layer 6, and enter the box 1 through the air vent 3 to achieve air filtration, which can prevent mosquitoes and dust from entering the box and increase the protection of the fruit.

[0024] like Figure 1 , Figure 2 as well as Figure 3 As shown, the shielding sheet does not correspond to the ventilation port 3 with a tear-off section 7. Several tear-off sections 7 are provided. In this embodiment, several tear-off sections 7 are spaced apart along the corrugated length of the corrugated cardboard. The shielding sheet has protrusions 8 at both ends corresponding to the tear-off sections 7. The operator can tear off the tear-off section 7 through the protrusions 8, changing the length of the flow path of the outside air to the filter layer 6, thereby changing the smoothness of the air flowing into the box 1. When it is necessary to increase the ventilation speed inside the carton, the number of torn tear-off sections 7 can be increased to increase the speed at which the air passes through the filter layer 6 and the ventilation port 3, ensuring that the ventilation speed of the carton is adapted to the needs of the fruit filled inside.

[0025] In summary, the cardboard box provided in this embodiment can change the ventilation speed of the cardboard box to adapt to the needs of the fruit filled inside. At the same time, the air is filtered during ventilation to prevent mosquitoes and dust from entering the cardboard box, thus ensuring the protection of the fruit.

[0026] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
