The plastic zipper 208 and the zipper head 209 seal the upper end of the bag 1, thereby realizing the waterproof function of the bag 1, solving the problem that the existing portable paper bag does not have the waterproof function, when the paper bag encounters water, it is easy to get wet and damaged, and cannot hold items, so that the bag 1 has increased waterproof performance and improved the safety of the bag 1 to hold items;

The hand rope structure 3 includes a fixing block 301, on which a hand rope 302 is installed through a connecting hole, and a spring buckle 303 is slidably connected to the outer wall of the hand rope 302, and the other end of the spring buckle 303 is provided with a connecting block 304; press the button on the spring buckle 303, pull the hand rope 302 to the left, release the button of the spring buckle 303, and the spring buckle 303 fixes the position of the hand rope 302 to shorten the length of the hand rope 302, thereby realizing the length adjustment function of the hand rope 302, solving the problem that the length of the hand rope 302 on the existing hand paper bag cannot be adjusted, which is inconvenient for people with shorter height or children to use, and the problem that the hand rope 302 is too long and causes the bottom of the bag to drag on the ground, thereby improving the flexibility of the bag 1 and also expanding the applicable population of the bag 1.

1, 3 and 6, the inner wall of the first nylon cloth layer 201 is connected to the outer wall of the bag 1, and the upper side of the inner wall of the bag 1 is connected to the third PVC waterproof material layer 204; the side walls of the second nylon cloth layer 206 and the fourth PVC waterproof material layer 207 are fixedly connected to the third PVC waterproof material layer 204, and the upper end of the bag 1 is connected to the bottom of the second PVC waterproof material layer 203; the side walls of the fixing block 301 and the connecting block 304 are fixedly connected to the first PVC waterproof material layer 202; one end of the hand rope 302 successively penetrates the upper and lower holes of the spring buckle 303; one end of the hand rope 302 successively penetrates the upper and lower holes of the spring buckle 303, and when the button of the spring buckle 303 is pressed, the hand rope 302 is pulled to the left, so that both ends of the hand rope 302 are shortened at the same time, thereby realizing the function of shortening the hand rope 302;

1 and 6 , the thickness of the bag 1 and the paper layer 205 is 0.3 mm, the thickness of the first nylon cloth layer 201 and the second nylon cloth layer 206 is 0.25 mm, the thickness of the first PVC waterproof material layer 202, the second PVC waterproof material layer 203, the third PVC waterproof material layer 204 and the fourth PVC waterproof material layer 207 is 0.25 mm; the length and width of the paper layer 205, the second nylon cloth layer 206 and the fourth PVC waterproof material layer 207 are the same; the third PVC waterproof material layer 202 04 is matched with the bag 1, and the structures of the fixing block 301 and the connecting block 304 are the same; the length and width of the paper layer 205, the second nylon cloth layer 206 and the fourth PVC waterproof material layer 207 are the same, and the paper layer 205, the second nylon cloth layer 206 and the fourth PVC waterproof material layer 207 are more matched, so that the second nylon cloth layer 206 and the fourth PVC waterproof material layer 207 can double-layer waterproof the paper layer 205, and the upper port of the bag 1 can be sealed, and the interior of the bag 1 can be waterproofed;

Working principle: when water contacts the outer wall and bottom of the bag 1, the first PVC waterproof material layer 202 provides the first layer of protection for the outer wall and bottom of the bag 1, and the first nylon cloth layer 201 provides the second layer of protection for the outer wall and bottom of the bag 1. When water is about to enter the interior of the bag 1 from the upper end of the bag 1, the fourth PVC waterproof material layer 207 provides the first layer of protection for the end surface of the paper layer 205, and the second nylon cloth layer 206 provides the second layer of protection for the end surface of the paper layer 205. The zipper head 209 fits the plastic zippers 208 on the front and back sides together, so that the water at the upper end of the bag 1 cannot enter the interior, so that the bag 1 has a waterproof function, which solves the problem that the existing portable paper bags do not have a waterproof function. When the paper bags encounter water, they are easily wetted and damaged, and cannot contain items. The waterproof performance of the bag 1 is increased, and the safety of the bag 1 for containing items is improved;

The user presses the button on the spring buckle 303 with one hand, and the spring buckle 303 no longer restricts the hand rope 302. The user pulls the hand rope 302 to the left with the other hand, and the hand rope 302 slides to the left in the hole of the spring buckle 303. The length of the hand rope 302 is adjusted according to the height of the user, and then the button on the spring buckle 303 is released. The spring buckle 303 fixes the position of the hand rope 302, which solves the problem that the length of the hand rope 302 on the existing portable paper bag cannot be adjusted, which is inconvenient for people with shorter height or children to use, and the hand rope 302 is too long and causes the bottom of the bag to drag on the ground. The flexibility of the bag 1 is improved, and the applicable population of the bag 1 is also expanded.

The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
