[0033] In one embodiment of this utility model, such as Figures 1-5 As shown, a waterproof storage bag for stationery is provided, including a document bag body 10 made of waterproof material. The document bag body 10 is provided with a storage cavity 11 for storing items and a bag opening communicating with the storage cavity 11. It also includes a sealing structure provided at the bag opening. The sealing structure includes a sealing lip 20 and a zipper 30. The zipper 30 is connected to the document bag body 10 and is used to control the opening and closing of the bag opening. The sealing lip 20 is connected to one side of the bag opening of the document bag body 10 and is provided with a snap-fit structure. A cavity for accommodating the zipper 30 is formed inside the sealing lip 20. The sealing lip 20 is closed to seal the zipper 30 and the storage cavity 11.
[0034] Specifically, the document bag body 10 is made of waterproof material and has a storage cavity 11 and a bag opening. A sealing structure is located at the bag opening and is connected to the bag opening of the document bag body 10, used to control the opening and closing of the bag. A sealing lip 20 is connected to one side of the bag opening of the document bag body 10 and is part of the sealing structure, forming an integral structure with the document bag body 10. A zipper 30 is connected to the document bag body 10 and passes through the cavity formed within the sealing lip 20, used to control the opening and closing of the bag, and is also accommodated by the cavity of the sealing lip 20.
[0035] Furthermore, a zipper 30 is used to control the opening and closing of the bag opening. When the zipper 30 is pulled open, the bag opening is open, allowing items to be stored and retrieved; the sealing lip 20 is provided with a convex-concave buckle structure, which closes the sealing lip 20 when the zipper 30 is pulled closed, thereby sealing the storage cavity 11 and preventing moisture and dust from entering.
[0036] The sealing lip 20 and the embossed buckle structure enhance the bag's airtightness, effectively preventing moisture from seeping into the storage cavity 11 and protecting the internal items from water damage. The zipper 30 makes opening and closing the bag simple and quick, allowing users to easily control the opening and closing, improving convenience. The cavity formed within the sealing lip 20 conceals the zipper 30 when not in use, providing a neat appearance and preventing direct contact between the zipper 30 and the outside environment, reducing the risk of damage. Because the document bag body 10 is made of waterproof material, combined with the sealing structure, this waterproof storage bag is suitable for various environments, including outdoors, rainy areas, or occasions where keeping items dry is crucial.
[0037] In this example, the sealing lip 20 includes a first lip 21 and a second lip 22, with the two ends of the first lip 21 and the two ends of the second lip 22 connected to each other. A groove 211 is provided on the inner side of the first lip 21; a protrusion 221 is provided on the inner side of the second lip 22, the protrusion 221 being opposite to and fitted with the groove 211, forming a snap-fit structure. Specifically, both the first lip 21 and the second lip 22 are connected to and opposite to the document bag body 10, and are connected to each other through their respective ends to form a closed annular structure, which constitutes the basis of the sealing lip 20. The groove 211 is provided on the inner side of the first lip 21, while the protrusion 221 is provided on the inner side of the second lip 22. These two structures correspond to each other, with the protrusion 221 fitting into the groove 211 to form a snap-fit structure.
[0038] Furthermore, when the sealing lip 20 needs to be closed, the protrusion 221 of the second lip 22 inserts into the groove 211 of the first lip 21. Due to the fit between the protrusion 221 and the groove 211, this structure can close tightly, ensuring the sealing performance of the sealing lip 20. To open the sealing lip 20, simply apply external force to dislodge the protrusion 221 of the second lip 22 from the groove 211 of the first lip 21, thereby releasing the snap-fit structure and opening the sealing lip 20.
[0039] Furthermore, the convex-concave snap-fit structure provides a robust connection, ensuring a tight seal on the sealing lip 20. This effectively prevents moisture and dust from entering the storage cavity 11, enhancing the document bag's waterproof and dustproof performance. The design of the convex-concave snap-fit structure makes opening and closing the sealing lip 20 simple and quick; users can easily open and close it with a simple insertion or removal motion, improving usability. The convex-concave snap-fit structure reduces wear at the connection points of the sealing lip 20 because the fit between the protrusion 221 and the groove 211 reduces stress concentration at the connection, thereby extending the lifespan of the sealing lip 20. When the sealing lip 20 is closed, the convex-concave snap-fit structure provides a smooth and continuous appearance, without any extra gaps or protrusions, making the overall appearance of the document bag neater and more aesthetically pleasing.
[0040] In this example, both the first lip 21 and the second lip 22 are integrally formed with the document bag. Specifically, the first lip 21 extends directly from the edge of the opening of the document bag body 10 without any additional connection or stitching. Similarly, the second lip 22 is also integrally formed with the document bag body 10, extending from the other edge of the document bag body 10 and corresponding to the first lip 21. Because they are integrally formed, this structure provides stronger stability and sealing. By reducing the risk of wear and tear at the joints, the integrally formed sealing lip 20 reduces long-term maintenance costs and replacement needs.
[0041] In this example, the document bag body 10 has a partition 40 inside, which divides the storage cavity 11 into a first storage cavity 111 and a second storage cavity 112. Specifically, the partition 40 is an internal structure of the document bag body 10, directly connected to the inner wall of the document bag body 10, dividing the storage cavity 11 into two independent storage spaces for storing different items. The partition 40 inside the document bag body 10 is designed to divide the storage cavity 11 into two storage cavities, allowing different types of items to be stored separately, improving storage efficiency and retrieval speed.
[0042] Furthermore, the compartment 40 can be fixed or movable. The fixed compartment 40 can be fixed to the document bag body 10 by gluing or sewing, while the movable compartment 40 can be connected to the document bag body 10 by zipper 30, Velcro or other fastening mechanisms, allowing the user to adjust the size of the storage compartment or fully open the space as needed.
[0043] In this example, the compartment 40 includes a first surface 41, which is disposed in the first storage cavity 111. Several strip-shaped storage bags 42 are disposed on the first surface 41, with the opening direction of each strip-shaped storage bag 42 aligned with the opening direction of the document bag body 10. Specifically, the first surface 41 has several strip-shaped storage bags 42, which are part of the compartment 40 and are directly connected to the first surface 41. These bags are used to store long and thin items, such as pens and rulers. The design of the compartment 40 effectively divides the internal space of the document bag, and the strip-shaped storage bags 42 on the first surface 41 provide additional categorized storage space. Users can place long and thin items into the strip-shaped storage bags 42, while placing other items in the remaining space of the first storage cavity 111, preventing these items from rolling or becoming disorganized inside the document bag and improving storage efficiency.
[0044] Furthermore, the opening direction of the strip-shaped binder bag 42 is consistent with the opening direction of the document bag body 10. This means that when the document bag is opened, the strip-shaped binder bag 42 also opens. When the user opens the document bag, they can see all the items inside the binder bag at a glance, making it convenient to quickly retrieve them.
[0045] In this example, the first side 41 is also provided with a storage bag 43, which is located next to the strip-shaped storage bag 42 and close to the bottom of the first storage cavity 111. Specifically, the design of the storage bag 43 and the strip-shaped storage bag 42 allows users to classify and store items according to their characteristics and frequency of use. The storage bag 43 is suitable for storing larger or heavier items, such as erasers, while the strip-shaped storage bag 42 is suitable for storing long and thin items. Because the storage bag 43 is located near the bottom, users can easily take out items from the storage bag 43 when opening the file folder without having to search for or move items on top. The combination of the storage bag 43 and the strip-shaped storage bag 42 provides more classification options, helping users to better manage and organize their items.
[0046] In this example, the compartment 40 includes a second surface 44, which is disposed in the second storage cavity 112. A storage bag 45 is provided on the second surface 44, and the opening direction of the storage bag 45 is consistent with the opening direction of the document bag body 10. Specifically, the storage bag 45 is a structure on the second surface 44, directly connected to it, and is used to store items. The storage bag 45 on the second surface 44 provides additional storage space, allowing users to categorize and store items within the second storage cavity 112. The design of the storage bag 45 allows items to be secured in a specific area, preventing movement inside the document bag. The opening direction of the storage bag 45 is consistent with the opening direction of the document bag body 10, meaning that when the document bag is opened, the opening of the storage bag 45 also opens, facilitating user access to items.
[0047] In this example, a document storage pocket 50 is provided on the side opposite to the second side 44 of the document bag body 10 and the partition 40. The opening of the document storage pocket 50 is equipped with a sealing structure. Specifically, the sealing structure at the opening of the document storage pocket 50 can be a zipper, Velcro, button, or other closure mechanism to ensure that the opening of the document storage pocket 50 can be securely closed. The design of the document storage pocket 50 allows users to easily manage and access their important personal documents, improving the practicality of the document bag.
[0048] In this example, a tissue pouch 60 is also included, which is disposed on the outside of the document bag body 10. Specifically, the tissue pouch 60 is an additional structure of the document bag body 10, disposed on the outside of the document bag body 10. This design allows the tissue pouch 60 to form an integral part with the document bag body 10 while maintaining its independence. The design of the tissue pouch 60 allows users to take out tissues directly from the outside of the document bag without opening the document bag body 10, providing a convenient and quick way to access tissues.
[0049] Furthermore, to ensure that the tissues do not slip out or scatter during use, the tissue bag 60 may have an internal mechanism for securing the tissues, such as an elastic band or a lining with high friction. Alternatively, a snap-lock mechanism can be used to secure the tissues.
[0050] In this example, all four corners of the document bag body 10 are designed with rounded chamfers. Specifically, the four corners of the document bag body 10 all adopt a rounded chamfer design, replacing sharp edges with smooth curves. These rounded chamfers are located at the top and bottom edges of the document bag body 10, specifically at the junction of each corner. The rounded chamfers make the document bag more comfortable to hold, avoiding the discomfort that sharp edges may cause. The rounded chamfers can also reduce the risk of damage to other items or surfaces during placement or carrying.
[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
