Description

Technical Field

[0001] This utility model relates to the technical field of waterproof bags, specifically a waterproof foldable paper bag. Background Technology

[0002] The outer layer of waterproof foldable paper bags is made of special waterproof material, which can effectively resist water penetration and protect the contents from getting dry. However, how to waterproof the opening of the waterproof foldable paper bag to prevent external water from seeping in is a problem that urgently needs to be solved.

[0003] For example, the existing publication number CN222292422U discloses a waterproof foldable paper bag, including a bag body. Both sides of the bag body have through holes, and a carrying strap is installed inside each through hole. An adjustment mechanism is provided on the surface of one end of the carrying strap inside the bag body. The bag body also has a water-blocking mechanism inside, comprising two symmetrical water-blocking plates fixedly installed on the inner walls of both sides of the bag body. The front and rear ends of each water-blocking plate have elastic strips that connect to the front and rear inner walls of the bag body. Magnetic strips are fixedly connected to the opposite sides of each water-blocking plate, and the two magnetic strips are magnetically attracted to each other. Drainage holes are provided on both sides of the inner walls of the bag body. This utility model, by setting up a water-blocking mechanism and using magnetic strips to close the two water-blocking plates, achieves a sealing and water-blocking effect inside the bag. The water-blocking plates guide rainwater to drain through the drainage holes, preventing rainwater from falling into the bag body. This paper bag has a simple structure and is highly practical.

[0004] The waterproof foldable paper bag proposed in this design has a water baffle and magnetic strip on the upper part of the inner side of the bag to complete the waterproof closure.

[0005] The design flaw is that when the paper bag is subjected to external forces such as pulling or collisions during transport, the two sets of water-blocking plates connected by magnetic strips can easily open passively, causing external splash water to seep in. Utility Model Content

[0006] To address the problem of magnetic strips at the opening of paper bags being passively opened by external forces in existing technologies, this utility model provides a waterproof and foldable paper bag.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] This utility model discloses a waterproof foldable paper bag, comprising a waterproof paper bag assembly. The waterproof paper bag assembly includes a waterproof outer paper bag layer, a waterproof inner paper bag layer fixedly connected to the lower part of the waterproof outer paper bag layer, and an inner waterproof component provided on the upper part of the waterproof inner paper bag layer, which can provide double splash-proof protection against water ingress at the opening of the waterproof inner paper bag layer from the waterproof outer paper bag layer. A winding component is provided in the middle of the inner waterproof component and the waterproof inner paper bag layer, which can roll the inner waterproof component inward to prevent the inner waterproof component from being accidentally opened.

[0009] As a preferred technical solution of this utility model, the waterproof paper bag assembly further includes a first outer waterproof sealing strip and a second outer waterproof sealing strip. The first outer waterproof sealing strip and the second outer waterproof sealing strip are respectively fixedly connected to the upper inner side of the waterproof outer paper bag layer, and the first outer waterproof sealing strip and the second outer waterproof sealing strip are interlocked with each other.

[0010] As a preferred technical solution of this utility model, the waterproof paper bag assembly further includes a handle, which is located on the outside of the waterproof outer paper bag layer.

[0011] As a preferred embodiment of the present invention, the waterproof paper bag assembly further includes a waterproof membrane layer, which is fixedly connected inside the waterproof inner paper bag layer.

[0012] As a preferred embodiment of the present invention, the winding assembly includes a winding bag, which is fixedly connected to the top opening of the waterproof inner paper bag layer.

[0013] As a preferred embodiment of the present invention, the winding assembly further includes a Velcro noodle group, which is fixedly connected to the lower part of one side of the winding bag. The winding assembly also includes a Velcro hook noodle group, which is fixedly connected to the upper part of one side of the winding bag.

[0014] As a preferred embodiment of this utility model, the inner waterproof component includes an opening and closing sleeve, which is fixedly connected to the top of the roll-up bag. A first inner waterproof sealing strip and a second inner waterproof sealing strip are fixedly connected to the inner side of the slot at the top of the opening and closing sleeve, and the first inner waterproof sealing strip and the second inner waterproof sealing strip are interlocked with each other.

[0015] The beneficial effects of this utility model are:

[0016] This type of waterproof foldable paper bag features a roll-up assembly and an inner waterproof assembly on the upper part of the waterproof inner paper bag layer. After the waterproof inner paper bag layer has stored the documents, the first and second inner waterproof sealing strips are first sealed and fastened together. Then, the roll-up bag is rolled up on the upper part of the waterproof inner paper bag layer until the hook and loop fasteners come into contact and are glued together. At this point, the first and second inner waterproof sealing strips, which are interlocked, are rolled up inside the roll-up bag. Subsequently, the first and second outer waterproof sealing strips are used to seal and fasten the outer waterproof paper bag layer. Compared to the previous design, this design uses the first and second inner waterproof sealing strips to independently seal the waterproof inner paper bag layer, achieving double waterproof protection. At the same time, the roll-up bag, which is glued and fixed after being rolled up, effectively prevents the first and second inner waterproof sealing strips from being accidentally opened, thereby achieving stable waterproofing during the transfer and movement of the waterproof inner paper bag layer.
