[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] The embodiments of this utility model will be described below based on its overall structure.

[0023] An antibacterial and UV-resistant plastic paper bag, such as Figures 1 to 5 As shown, the bag includes a bag body 100, and two sets of U-shaped reinforcing ribs 150 are longitudinally wrapped inside the bag body 100. The top of the two sets of U-shaped reinforcing ribs 150 is connected to a hollow rope 120 extending to the top of the bag body 100. The bottom of the bag body 100 is wrapped with a bottom plate 160, and the bottom plate 160 is fixed inside the two sets of U-shaped reinforcing ribs 150.

[0024] A constraint frame 110 is fixed on the inner wall of the bag body 100 near the top opening. The inner wall of the constraint frame 110 is provided with two sets of strips 130 that are rotatably connected to the inner wall of the bag body 100. Two sets of auxiliary ropes 140 that are fixedly connected to the outer wall of the hollow rope 120 are fixed on the top of the strips 130.

[0025] When the hollow rope 120 is used to move the bag 100, the weight of the items inside the bag 100 causes the two ends of the hollow rope 120 to slide upward a certain distance on the outer wall of the U-shaped reinforcing rib 150. At this time, the auxiliary rope 140 will be pulled up and kept taut. Since the bottom of the constraint frame 110 obstructs the slats 130, the two sets of slats 130 rotate around the connection point with the bag 100 to a horizontal state, sealing the top of the bag 100. This can prevent the intrusion of dust and other dirt, and at the same time prevent other users from stealing the items inside the bag 100 without noticing.

[0026] The U-shaped reinforcing ribs 150 and the bottom plate 160 allow the force of the hollow handle rope 120 to be transmitted upwards from the bottom of the bag body 100, increasing the toughness of the bottom of the bag body 100 and effectively preventing the bottom of the bag body 100 from breaking due to the weight of the items. At the same time, it increases the connection force between the hollow handle rope 120 and the bag body 100, ensuring that the two will not easily separate, thus extending the service life of the bag body 100.

[0027] Please refer to this carefully. Figure 1 A waterproof membrane 180 is pasted on the inner and outer surfaces of the bag body 100, and an ultraviolet-proof layer 190 is installed on the outer side of the bag body 100 between the waterproof membrane 180 and the bag body 100.

[0028] A waterproof membrane 180 is used to prevent water from wetting the bag, while a UV-protective layer 190 is used to prevent damage to the items inside the bag 100.

[0029] Please refer to this carefully. Figure 2 The bag body 100 includes multiple sets of aramid ropes 170 in the horizontal direction. The multiple sets of aramid ropes 170 are evenly distributed inside the bag body 100. The inner side of the multiple sets of aramid ropes 170 is fixed with a longitudinal strip, and the bottom end of the longitudinal strip is fixed to the top of the bottom plate 160.

[0030] The use of aramid rope 170 increases the toughness of the bag body 100, preventing the items stored inside from tearing the bag body 100. It also prevents others from cutting open the bag body 100 from the outside to steal the items inside, thus providing a certain degree of protection for the items stored in the bag body 100.

[0031] Please refer to this carefully. Figure 2 The two ends of the hollow rope 120 are sleeved on the top of the U-shaped reinforcing rib 150, and the outer wall of the U-shaped reinforcing rib 150 is provided with a travel groove 151 near the top.

[0032] A metal sleeve 121 is fixed to the end of the hollow rope 120. The metal sleeve 121 is slidably sleeved on the outer wall of the U-shaped reinforcing rib 150. A constraint block 122 is fixed to the inner wall of the metal sleeve 121 and is slidably disposed with the stroke groove 151.

[0033] The travel groove 151 limits the upward travel of the metal sleeve 121 and the constraint block 122, preventing the hollow rope 120 from separating from the U-shaped reinforcing rib 150, so that the bag body 100 can be moved by lifting the hollow rope 120.

[0034] Please refer to this carefully. Figure 3 The top of the bag body 100 has a circular channel 101 for the hollow rope 120 to slide.

[0035] The hollow rope 120 can be raised and lowered slightly, so that when the user holds the hollow rope 120, the strip 130 can seal the top of the bag 100.

[0036] When in use, when the hollow rope 120 is held to move the bag 100, the weight of the items inside the bag 100 causes the two ends of the hollow rope 120 to slide upward a certain distance on the outer wall of the U-shaped reinforcing rib 150. At this time, the auxiliary rope 140 will be pulled up and kept taut. Since the bottom of the constraint frame 110 obstructs the slats 130, the two sets of slats 130 rotate around the connection point with the bag 100 to a horizontal state, sealing the top of the bag 100. This can prevent the intrusion of dust and other dirt, and at the same time prevent other users from stealing the items inside the bag 100 without noticing.

[0037] The U-shaped reinforcing ribs 150 and the bottom plate 160 allow the force of the hollow handle rope 120 to be transmitted upwards from the bottom of the bag body 100, increasing the toughness of the bottom of the bag body 100 and effectively preventing the bottom of the bag body 100 from breaking due to the weight of the items. At the same time, it increases the connection force between the hollow handle rope 120 and the bag body 100, ensuring that the two will not easily separate, thus extending the service life of the bag body 100.

[0038] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the present invention, provided that such modifications, substitutions, and variations are within the scope of the claims of the present invention and are protected by patent law.
