Description

Technical Field

[0001] The utility model relates to the technical field of document bags, in particular to a waterproof sealed document bag. Background Art

[0002] A document bag is a bag used to store documents and other materials. It's typically made of paper, plastic, or non-woven fabric. It organizes, organizes, and protects various documents, making it easier to store and carry them. Sealable document bags feature a closure, such as a zipper, snap button, or butt-strip closure. This prevents documents from falling out of the bag and being lost, while also effectively blocking dust, moisture, and other external factors from entering the bag.

[0003] A document bag with a butt-strip seal primarily consists of a bag body and a butt-strip seal. The bag body is used to hold documents, while the butt-strip seal is typically located at the bag opening. It typically features a soft raised strip on one side and a corresponding groove on the other. The seal works by tightly squeezing the raised strip and groove together, leveraging the elasticity or friction of the material to seal the bag opening, preventing documents from falling and protecting them.

[0004] In the prior art, since the sealing of the butt joint strips mainly relies on the squeezing and fitting of the raised strips and the grooves, this connection method is difficult to achieve completely tight and seamless. Moisture can easily penetrate through the tiny gaps, making it difficult to seal and waterproof some file bags. As a result, the documents will be soaked in water, making the handwriting on the documents blurred and the paper damaged. In addition, the documents will become damp and moldy, breeding bacteria and pests, thereby accelerating the aging and damage of the documents. Therefore, a waterproof sealed file bag is proposed to solve the above problems. Utility Model Content

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] Reference Figures 2 to 4The utility model provides an embodiment: a waterproof sealed file bag, comprising a bag body 1. The bag body 1 serves as the main part of the file bag and bears the main function of accommodating documents. A waterproof interlayer is provided inside the bag body 1. The material of the waterproof interlayer is polyethylene (PE) film. Polyethylene is a common thermoplastic plastic with good waterproof properties. Its molecular structure is tight and it is difficult for water molecules to penetrate. When used as a waterproof interlayer of a file bag, it can form a continuous barrier between the bag body 1 and the documents. Its crystalline part can prevent the diffusion of water molecules, while the non-crystalline part provides a certain degree of flexibility. At the same time, it is relatively light and will not add too much weight to the file bag, making it easy to carry. One end of the bag body 1 is fixedly connected to a bag opening 2, which provides an opening and closing area for the entire file bag. A sealing mechanism is fixedly connected to the inner wall of the connection between the bag body 1 and the bag opening 2, and a portable mechanism is fixedly connected to the other end of the bag opening 2;

[0028] The sealing mechanism includes a lower seal 3, the bottom of which is fixedly connected to the bottom inner wall of the connection between the bag opening 2 and the bag body 1, and the top of the lower seal 3 is fixedly connected to a blocking assembly, which is used to further seal the entire document bag. An upper seal 11 is fixedly connected to the top inner wall of the connection between the bag opening 2 and the bag body 1, and the upper seal 11 and the lower seal 3 cooperate with each other to form a sealing line of defense at the bag opening 2. When the bag opening 2 is closed, the upper seal 11 fits tightly with the lower seal 3, thereby providing basic sealing performance for the document bag, reducing the contact between the documents in the bag and the external environment, and reducing the risk of contamination or damage to the documents. The bottom of the upper seal 11 is fixedly connected to a positioning assembly, which is used to prevent the document bag from shifting when opening and closing, thereby increasing the risk of leakage.

[0029] The sealing assembly includes a blocking strip 4, the bottom of which is fixedly connected to the top of the lower seal 3, and the top of which is detachably connected to the bottom of the upper seal 11. The blocking strip 4 is used to provide a foundation for the docking of the upper seal 11 and the lower seal 3, and at the same time, squeeze out the air inside the upper seal 11 when the upper seal 11 and the lower seal 3 are closed, thereby forming a stable sealing structure. Two rubber strips 5 are fixedly connected to both sides of the blocking strip 4, and two filling grooves are respectively provided on the left and right sides of the inner wall of the upper seal 11. The outer wall of the rubber strip 5 contacts the inner wall of the filling groove, thereby utilizing the elastic deformation of the rubber strip 5 to fill the small gap between the upper seal 11 and the blocking strip 4, forming a tighter seal and further enhancing the waterproof performance of the document bag. Compared with relying solely on the sealing of the upper seal 11 and the lower seal 3, the filling of the rubber strip 5 makes it more difficult for moisture to penetrate into the bag.

[0030] The positioning assembly includes two positioning strips 6, the tops of which are fixedly connected to the bottom of the upper seal 11. The positioning strips 6 are used in conjunction with subsequent structures to precisely position the entire sealing mechanism. The top of the lower seal 3 has two positioning slots 7, and the bottom of the upper seal 11 is removably connected to the interior of the positioning slots 7. When the bag opening 2 is closed, the positioning strips 6 at the bottom of the upper seal 11 insert into the positioning slots 7 of the lower seal 3. The precise fit between the positioning strips 6 and the positioning slots 7 ensures that the bag opening 2 is accurately closed, ensuring that the upper seal 11, lower seal 3, and the sealing assembly can perform their sealing function in the correct position.

[0031] Reference Figures 1 to 2 The portable mechanism includes two handles 8, one end of each handle 8 is fixedly connected to the other end of the bag opening 2. The design of the handles 8 makes it easy for users to carry the document bag, whether it is carried by hand or hung on a hook. The structure of the handles 8 evenly distributes the weight of the document bag on the handles 8, reducing the pressure on the user's hands. Two magnetic blocks 9 are fixedly connected to the adjacent sides of the two handles 8. When the document bag is not in use, the magnetic blocks 9 on the two handles 8 attract each other, causing the handles 8 to automatically fit together, avoiding the risk of the document bag automatically opening due to external force, causing the internal documents to accidentally fall out. A note board 10 is fixedly connected to the outer wall of the bag body 1. The note board 10 provides users with an area for conveniently marking the contents of the document bag, allowing users to briefly record relevant information about the documents in the document bag, such as the file name, project to which it belongs, date, etc., to facilitate the classification management and quick search of documents.

[0032] Working principle: The waterproof barrier layer of the bag body 1 of the document bag is made of polyethylene (PE) film, and its tight molecular structure naturally blocks water molecules. When the bag opening 2 is closed, the upper seal 11 fits tightly with the lower seal 3, initially building a sealing defense line. And during the closing process of the bag opening 2, the blocking strip 4 moves as the upper seal 11 and the lower seal 3 approach each other, squeezing out the air inside the upper seal 11 and forming a stable sealing structure. At the same time, the rubber strips 5 on both sides of the blocking strip 4 move with the blocking strip 4 and are squeezed into the filling groove on the inner wall of the upper seal 11. The elastic deformation of the rubber strip 5 fills the tiny gap and further strengthens the sealing effect. The positioning strip 6 of the positioning assembly moves with the upper seal 11 and is inserted into the positioning groove 7 of the lower seal 3. Through this precise coordination, it is ensured that all components of the entire sealing mechanism function in the correct position, so that the document bag as a whole forms a stable and efficient waterproof sealing system, effectively blocking water molecules, dust and other foreign substances from entering the bag, protecting the safety of documents.

[0033] The design of the two handles 8 allows the weight of the file bag to be evenly distributed on the handles 8, making it easy for users to carry it. When the file bag is not in use, the magnetic blocks 9 on the two handles 8 attract each other. The magnetic force generated by the magnetic blocks 9 drives the handles 8 to move closer to each other, so that the handles 8 automatically fit together, avoiding the file bag from automatically opening due to unexpected situations such as external collisions or shaking, thereby preventing the documents inside from accidentally falling out. In addition, the note board 10 on the outer wall of the bag body 1 provides users with a convenient file information identification area, on which users can record file-related information. During the file management process, by viewing the information on the note board 10, files can be quickly located and classified, greatly improving the convenience of file use and management. Whether in daily office or learning scenarios, users can operate the file bag and its internal documents more efficiently.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
