Description

Technical Field

[0001] This utility model relates to the field of packaging carton technology, specifically a novel carton with a moisture-proof and damp-proof interlayer. Background Technology

[0002] Cardboard boxes are a common packaging material used in people's daily lives and work. Many workers or households use higher-quality cardboard boxes to store items for extended periods, such as temporarily unused documents, clothing, and sundries. However, the quality of these cardboard boxes is only reflected in their thickness and material strength. Over time, they will still become damp, moldy, and rotten, affecting the items inside.

[0003] Therefore, in order to correct the above-mentioned defects, we propose a new type of cardboard box with a layered moisture barrier. Utility Model Content

[0004] The technical problem solved by this utility model is to propose a new type of cardboard box with a layered structure that blocks moisture and prevents dampness.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a novel cardboard box with a layered moisture barrier, comprising an outer box body and a box lid. The outer box body consists of four sides and a bottom. Inside the outer box body is an open inner box body. A vertical receiving groove is provided on one of the exposed sides. A rotating shaft is installed on the inner top of the receiving groove and the inner top of the inner top. A shaft is connected between the two rotating shafts. A transparent film is wrapped around the outside of the shaft body in several turns.

[0006] Furthermore, there is a gap between the outer casing and the uncovered inner casing, and the gap is filled with activated carbon particles.

[0007] Furthermore, a seal is movably embedded in the opening of the receiving slot, and one side of the seal is integrally connected to the exposed side of the box edge.

[0008] Furthermore, the outer wall of the outer casing is covered with an outer waterproof membrane.

[0009] Furthermore, the inner wall of the lidless inner box is covered with waterproof oil paper.

[0010] Compared with the prior art, the beneficial effects of this utility model are: the cardboard box of this utility model adopts a layered design with activated carbon particles between the two layers, which can play a good role in moisture prevention. In addition, the box body comes with a rolled transparent film. When sealing, the transparent film can be used to seal the entire cardboard box, which can better play the role of moisture prevention and dampness prevention. Attached Figure Description

[0011] Figure 1 This is a schematic diagram of the main structure of this utility model; Figure 2 This is a schematic diagram of the main structure of the middle box side of this utility model; Figure 3 This is a top view of the side structure of the middle box of this utility model. Detailed Implementation

[0012] 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.

[0013] This utility model provides a technical solution: Please see Figure 1-3 A novel cardboard box with a layered moisture barrier includes an outer box body 1 and a box lid 2. The outer box body 1 consists of four box sides 11 and a box bottom. Inside the outer box body 1, there is an open inner box body 3. The top of the open inner box body 3 is flush with the top of the outer box body 1. A vertical receiving groove 5 is opened on one of the exposed sides 11. A rotating shaft 6 is installed on the inner top of the receiving groove 5 and the inner top of the inner top. A shaft rod 7 is connected between the two rotating shafts 6. A transparent film 8 is wrapped around the outside of the shaft rod 7 in several turns. The rotating shaft 6 is actually a ring made of paper material, which is glued to the receiving groove 5. The shaft 7 is also a round rod made of paper material, with both ends of the rod inserted into the two rings.

[0014] When the item is placed inside the open inner box 3, close the box lid 2, and then pull one end of the transparent film 8 so that the transparent film 8 is gradually unrolled from the shaft 7. At the same time as unrolling, wrap the unrolled transparent film 8 around the outer box 1. Since the transparent film 8 is soft, the film can be turned when wrapped around the box, so that the box can be wrapped 360°.

[0015] There is a gap between the outer casing 1 and the uncovered inner casing 3, which is filled with activated carbon particles 4 to prevent the inner casing from getting damp.

[0016] In order to prevent the unrolled film from getting contaminated, a seal 9 is movably embedded in the opening of the receiving groove 5. The seal 9 is made of the same paper material as the box body. One side of the seal 9 is integrally connected to the exposed side of the box edge 11. That is, initially, the seal 9 blocks the opening of the receiving groove 5. When the film is needed, the seal 9 is pulled open.

[0017] The outer box 1 has an outer waterproof membrane attached to its outer wall. The outer waterproof membrane is made of polyethylene or polypropylene plastic film, which can block external liquid water while maintaining the printability of the carton surface. The inner wall of the lidless inner box 3 is attached with waterproof oil paper to prevent the contents from directly contacting the box wall.

[0018] 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.
