[0008] Preferably, the filtering structure includes a mesh sheet, the mesh sheet is fixed on the top surface of the bottom plate of the flexible waterproof兜, and the size of the mesh sheet is larger than the notch size of the water drainage area.
[0009] Preferably, the water drainage area includes a water drainage port, and the water drainage port penetrates through the bottom plates of the flexible waterproof兜 and the paper handbag body.
[0010] Preferably, a pressing groove is integrally formed on the bottom surface of the paper handbag body, and the pressing groove is in a "匚"-shaped groove for installing the seal.
[0011] Preferably, the sealing member comprises a waterproof gasket and a water-absorbing sponge block fixed on the surface of the waterproof gasket, one end of the waterproof gasket is fixed on the surface of the pressing groove, the surface of the waterproof gasket is bonded to the surface of the pressing groove by double-sided tape, and the water-absorbing sponge block is inserted into the drain port.
[0012] Preferably, a tear sheet is fixed to the other end of the waterproof gasket.
[0013] Compared with the prior art, the beneficial effects of the utility model are:
[0014] The waterproof paper handbag proposed by the utility model has a water collecting chamber at the bottom of the paper handbag body to prevent the bag bottom from being broken due to water leakage, and a water drainage area is provided at the bottom of the paper handbag body to facilitate the drainage of the leaked water; the problem of the existing paper handbag bottom being broken due to water leakage inside the bag is further solved, and the water leakage at the bag bottom can be drained.

[0021] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are part of the embodiments of the utility model, not all of the embodiments, and are only used to explain the embodiments of the utility model, and are not used to limit the embodiments of the utility model. All other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figures 1 to 5, the present utility model provides a technical solution: a waterproof paper handbag, including a paper handbag body 1, a waterproof film 2 is attached to the inner wall of the paper handbag body 1, a water collecting bin is provided at the bottom of the paper handbag body 1, the water collecting bin includes a flexible waterproof兜 3, the flexible waterproof兜 3 is in a square frame structure, the height of the flexible waterproof兜 3 is less than the height of the paper handbag body 1, a filtering structure is laid at the bottom of the flexible waterproof兜 3 to prevent items from falling from the water discharge area; the filtering structure includes a mesh piece 5, the mesh piece 5 is fixed on the top surface of the bottom plate of the flexible waterproof兜 3, and the size of the mesh piece 5 is larger than the notch size of the water discharge area;
[0023] A water discharge area is provided at the bottom of the water collecting bin, the water discharge area includes a water discharge port 4, the water discharge port 4 penetrates through the bottom plates of the flexible waterproof兜 3 and the paper handbag body 1, and the bottom of the water discharge area is covered by a sealing member.
