Abstract
Description
Technical Field
[0001] This utility model relates to the field of folder technology, specifically to a PP foam folder with snap buttons. Background Technology
[0002] A folder is a tool specifically designed for storing files. The existing folder structure is simply a regular clip, with metal clips or file pockets used to hold files inside, offering only a single function. Summary of the Invention
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a PP foam folder with snap buttons.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A snap-button PP foam folder includes a spine and a foldable front cover and back cover connected to both sides of the spine. The front cover, spine, and back cover are integrally formed from a single piece of PP foam material. The inner and outer sides of the spine have multiple parallel creases. The inner side of the back cover has a metal clip for holding documents, and the metal clip has multiple dividers for holding. A buckle is connected to the middle of the outer side of the back cover, and the free end of the buckle is connected to a female buckle. The outer side of the front cover has a female buckle that mates with the female buckle.
[0006] Furthermore, the inner side of the face cover is provided with a transparent inner pocket.
[0007] Furthermore, the two sides of the buckle are connected to the outer center of the back cover by a rounded transition.
[0008] Furthermore, the buckle's turning points all employ a double-line crease structure.
[0009] Furthermore, a card pocket is provided in the center of the outer side of the face cover.
[0010] Furthermore, the upper part of the face cover is provided with a pen insertion hole.
[0011] The present invention adopts the above technical solution and has the following beneficial effects:
[0012] 1. The front cover, spine, and back cover of the file bag are molded from a single piece of PP foam sheet, which is relatively low-cost, thereby reducing the overall cost of the folder; in addition, PP foam sheet is lightweight and has a good feel, and can also provide folder surfaces with various textures to meet different market demands.
[0013] 2. A buckle has been added to the folder to secure it, improving file storage security. The buckle's bends feature a double-stitched crease structure for easy and flexible opening and closing. The sides of the buckle connect to the outer center of the back cover with a rounded transition to avoid stress concentration at the connection point.
[0014] 3. Configure dividers within the folder to facilitate file categorization and retrieval;
[0015] 4. The folder also features a transparent inner pocket, pen holder, and card slot, increasing its practicality and ease of use. Attached Figure Description
[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:
[0017] Figure 1 This is a schematic diagram of the structure of this utility model;
[0018] Figure 2 This is a diagram showing the folder after it has been expanded. Detailed Implementation
[0019] like Figure 1-2 As shown, this utility model discloses a PP foam folder with snap buttons, comprising a spine 1 and foldable front covers 2 and back covers 3 connected to both sides of the spine 1. The front covers 2, spine 1, and back covers 3 are integrally formed from a single piece of PP foam material. The spine 1 has multiple parallel creases 11 on its inner and outer sides, allowing it to extend and retract, thus increasing the storage capacity. The back cover 3 has metal clips 4 for holding documents on its inner side. These metal clips 4 are equipped with multiple dividers 5, which facilitate the classification, storage, and retrieval of documents within the folder.
[0020] A buckle 6 is connected to the middle of the outer side of the back cover 3. A female buckle is connected to the free end of the buckle 6. A female buckle is provided on the outer side of the front cover 2 to cooperate with the female buckle. This utility model adds a buckle 6 to the folder, which can be used to fasten and close the folder, improving the security of document storage. The bends of the buckle 6 all adopt a double-stitched crease structure 11, facilitating flexible opening and closing of the buckle. The two sides of the buckle 6 are connected to the middle of the outer side of the back cover 3 by an arc transition, avoiding stress concentration at the connection point.
[0021] The inner side of the cover 2 has a transparent inner pocket 7. The outer center of the cover 2 has a card slot 8. The top of the cover 2 has a pen slot 9. The inclusion of a transparent inner pocket 7, a pen slot 9, and a card slot 8 on the folder increases its practicality and makes it easy to use.
[0022] This utility model uses a single piece of PP foam sheet to integrally mold the front cover 2, back spine 1, and back cover 3 of the file bag, which has a relatively low cost, thereby reducing the overall cost of the folder; in addition, PP foam sheet is lightweight and has a good feel, and can also provide folder surfaces with various textures according to different market demands.
[0023] The specific embodiments of this utility model have been described above. However, those skilled in the art should understand that this is only an example. Those skilled in the art can make various changes or modifications to this embodiment without departing from the principle and essence of this utility model, but all such changes and modifications fall within the protection scope of this utility model.
