DETAILED DESCRIPTION

[0017] The following is combined with Figures 1 to 4 The utility model is described in detail.

[0018] The utility model discloses a carton with a reinforced waterproof structure, comprising a box body 1 and a paper cover 2. The box body 1 is composed of five paperboards. The inner wall of the box body 1 is provided with a first card slot 11 and a second card slot 12 near the opening end and the bottom of the box body 1, respectively. The first card slot 11 is provided with a first shaping frame 13, and the second card slot 12 is provided with a second shaping frame 14. The first shaping frame 13 and the second shaping frame 14 can support the four sides of the box body 1 to prevent the sides of the box body 1 from being concave and deformed. The two opposite sides of the outside of the box body 1 are provided with snap rings 15. The paper cover 2 is provided with a top plate 21, and the edge of the top plate 21 is provided with a vertically protruding baffle 22. The inner side of the baffle 22 can abut against the outer side of the open end of the box body 1. The edge of the top plate 21 is also provided with a silicone layer 23 that can abut against the end of the open end of the box body 1. After the paper cover 2 is placed on the box body 1, the rectangular groove formed by the top plate 21 and the baffle 22 seals the open end of the box body 1. The top of the box body 1 abuts the silicone layer 23, completely isolating the inside and outside of the box body 1, preventing moisture from entering the box body 1 through the gap, and achieving good sealing. The baffle 22 is provided with an elastic band 24 that can cooperate with the snap ring 15. After the paper cover 2 is placed on the box body 1, the connection between the elastic band 24 and the snap ring 15 is fixed, thereby locking the paper cover 2 to the box body 1, without the need for tools such as tape, making it easy to use. The outside of the box body 1, the top plate 21 and the baffle 22 are all provided with a waterproof membrane 3. Specifically, the outside of the box body 1 and the paper cover 2 are fully covered with the waterproof membrane 3. After the paper cover 2 is assembled and fixed to the box body 1, even if the carton of the present invention is completely immersed in water, water stains will not enter the interior of the box body 1, and the waterproof performance is high.

[0019] The first and second shaping frames 13, 14 are removably mounted within the first and second slots 11, 12. These frames support the sides of the shaping box 1, preventing deformation of the box 1 that could compromise its sealing performance. The first and second shaping frames 13, 14 are removable or replaceable based on user needs, providing enhanced convenience.

[0020] The first shaping frame 13, the second shaping frame 14, and the snap ring 15 are all made of plastic. The plastic first shaping frame 13, the second shaping frame 14, and the snap ring 15 have low manufacturing costs and a long service life. Furthermore, if the box body 1 is damaged and cannot be used, the first shaping frame 13, the second shaping frame 14, and the snap ring 15 can be assembled on other similar cartons for use.

[0021] The clamping ring 15 is provided with a fixing buckle 16. Two fixing buckles 16 are provided on each clamping ring 15 to fix the clamping ring 15 on the box body 1.

[0022] The baffle 22 is provided with a bayonet 25, and the elastic band 24 is fixed in the bayonet 25. After the elastic band 24 is fixed to the clamping ring 15, the elastic band 24 will exert tension on the baffle 22, and the bayonet 25 avoids the waterproof membrane 3, which can prevent the elastic band 24 from pulling and damaging the waterproof membrane 3.

[0023] The elastic band 24 has a certain degree of elasticity and is provided with a lock 26. After the paper cover 2 is placed on the box body 1, the elastic band 24 is stretched and wrapped around the clamp 15, and then the lock 26 is fastened to secure the elastic band 24. The carton of the utility model has high waterproofness, strong sealing performance, and is easy to use.

[0024] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
