And the outer wall of the waterproof seat below the waterproof cover is fixedly installed with a gasket. Moreover, knobs are arranged on the lower inner walls of both the front and back sides of the waterproof cover. The outer wall of the waterproof film below the waterproof seat is fixedly connected with a base, and the outer wall of the base is sleeved with a transparent cover.

[0008] Preferably, the male velcro surface and the female velcro surface are fitted together.

[0009] Preferably, the waterproof seat and the waterproof cover are slidably connected.

[0010] Preferably, the waterproof cover and the gasket are fitted together.

[0011] Preferably, the knob is threadedly connected to the waterproof seat and the waterproof cover respectively.

[0012] Preferably, the base and the transparent cover are provided with threads.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows: The waterproof high-low mouth envelope paper bag strengthens the waterproof ability, thereby avoiding the phenomenon that water enters the interior of the paper bag and causes damage to the items, and improving the practicability of the paper bag.

[0014] Through the folding of the inner paper bag, the female surface of the magic tape is attached to the male surface of the magic tape, thereby sealing the paper bag. Then, through the movement of the waterproof cover, the waterproof cover is sleeved outside the waterproof seat. At this time, the waterproof cover fits the gasket, thereby sealing the sealing part of the paper bag. Therefore, the waterproof ability of the paper bag is strengthened, thereby avoiding the phenomenon that water enters the interior of the paper bag and causes damage to the items, and improving the practicability of the paper bag.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figures 1-6 ,the present utility model provides a technical solution: a waterproof high-low mouth envelope paper bag, which includes an inner paper bag 1, a waterproof film 2, a male velcro surface 3, a female velcro surface 4, a waterproof seat 5, a waterproof cover 6, a washer 7, a knob 8, a base 9 and a transparent cover 10. The outer wall of the inner paper bag 1 is fixedly provided with the waterproof film 2, and the upper outer wall of the waterproof film 2 is fixedly connected with the male velcro surface 3, and the upper outer wall of the inner paper bag 1 is fixedly installed with the female velcro surface 4. The outer wall of the waterproof film 2 below the male velcro surface 3 is fixedly provided with the waterproof seat 5, and the upper outer wall of the waterproof seat 5 is sleeved with the waterproof cover 6, and the outer wall of the waterproof seat 5 below the waterproof cover 6 is fixedly installed with the washer 7, and knobs 8 are arranged on the lower inner walls on both front and rear sides of the waterproof cover 6. The outer wall of the waterproof film 2 below the waterproof seat 5 is fixedly connected with the base 9, and the outer wall of the base 9 is sleeved with the transparent cover 10.

[0024] The male velcro surface 3 and the female velcro surface 4 are attached to each other, which is convenient for sealing the paper bag by attaching the male velcro surface 3 and the female velcro surface 4.
