Description

Technical Field

[0001] This utility model relates to the field of shielding bag technology, and more specifically, to a novel zippered antistatic shielding bag. Background Technology

[0002] Shielding bags effectively isolate items from external electrostatic fields, preventing static electricity buildup inside the bag and protecting items from electrostatic hazards. They also protect against electromagnetic interference and are used for storing static-sensitive components such as PCBs and LEDs. When transporting electronic products, anti-static shielding bags are typically used to prevent static electricity buildup inside the bag from affecting the product's use. These bags maximize protection for static-sensitive components from potential electrostatic damage. Their unique Faraday cage structure creates an "induction shield" effect, achieving shielding and anti-static properties for the items inside.

[0003] However, existing shielding bags have the following problems when used:

[0004] Existing shielding bags mostly rely on a single self-sealing or zipper structure during use. They are prone to loosening due to bumps during use, which cannot guarantee the stability of the seal. This can lead to the intrusion of external dust or the falling of internal components, which can easily damage electronic components. Secondly, the bags lack a cushioning structure, making them difficult to withstand collisions during transportation. Alternatively, the cushioning layer may be fixed in place, increasing the volume and space occupied during static storage. Their storage adaptability is also insufficient.

[0005] This utility model can prevent items from falling and block dust through multiple sealing and fixing structures, and the folding end can flexibly adjust the volume. The protective cavity can buffer as needed, making it suitable for storage and transportation, and protecting items from damage throughout the process. Utility Model Content

[0006] The present invention aims to solve the technical problems mentioned in the background art and provide a novel zippered antistatic shielding bag.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a novel zipper-type antistatic shielding bag, comprising: a bag body, wherein a self-sealing groove is provided inside the bag body, a zipper is fixedly installed on the surface of the bag body, limiting holes are provided on both the left and right sides of the front side of the zipper, an inner cavity is provided inside the bag body, a folding end is fixedly installed at the front end of the bag body, a self-sealing groove is provided at the bottom of the inner cavity, a self-sealing rib is fixedly installed at the upper end of the inner cavity, the self-sealing rib is matched with the self-sealing groove, the limiting hole is provided on the upper end of the folding end near the zipper, the zipper is composed of a chain and a zipper head, and fixing posts are fixedly installed on both the left and right sides of the zipper, the fixing posts being embedded inside the limiting hole.

[0008] A further preferred embodiment: Velcro is fixedly installed on the upper surface of the bag body and the side of the upper end of the folded end near the zipper, and the two Velcros are glued to each other and detachably connected.

[0009] A further preferred embodiment: the upper surface and the back surface of the bag are provided with protective cavities, and compressed sponges are fixedly connected inside the protective cavities.

[0010] A further preferred embodiment: a sealing sticker is adhered to the rear side of the outer side of the protective cavity, and an air inlet is provided on the upper surface and the rear side of the back of the bag, with the sealing sticker affixed to the surface of the air inlet.

[0011] A further preferred embodiment: the zipper head of the zipper has a hollow pull ring, and the center of the pull ring is larger than the fixing post.

[0012] A further preferred embodiment: a limiting groove one is formed on the surface of the fixed column, and a limiting groove two is formed inside the limiting hole.

[0013] A further preferred embodiment: When the folding end is folded, the fixing post is embedded inside the limiting hole to form a press-fit buckle.

[0014] Beneficial effects:

[0015] 1. Equipped with folding ends, Velcro, self-sealing grooves, self-sealing ribs, and zippers, the folding ends allow for flexible adjustment of the folding range according to the height of items and storage needs, reducing the exposed area of ​​the bag opening. At the same time, they adhere to the bag body surface to further tighten the bag opening. The Velcro enhances the connection stability between the folding ends and the bag body, preventing the folding ends from lifting due to zipper loosening, thus improving overall sealing. The self-sealing groove and self-sealing ribs interlock to form an initial seal, preventing dust and items from falling in. After the zipper is closed, the seal is further reinforced, with its chain gripping the edge of the bag opening. Combined with the buckle structure of the fixing post and limiting hole, multiple fixation is achieved to prevent seal failure. These structures work together to ensure both sealing reliability and storage flexibility, adapting to different usage scenarios.

[0016] 2. With a protective cavity, sealing strip, and air inlet, the compressed sponge inside the protective cavity forms a cushioning layer, effectively reducing the impact of external collisions and compression on the internal items. The sealing strip fits the air inlet, keeping the compressed sponge compressed when cushioning is not needed, avoiding increasing the bag's thickness and saving storage space. When cushioning is needed, tearing off the sealing strip allows air to enter the protective cavity, causing the sponge to expand and provide protection. The air inlet provides an air passage for the sponge's expansion and, together with the sealing strip, prevents air loss after expansion, ensuring a stable cushioning effect.

[0017] 3. By setting a fixing post and a limiting hole, the two are embedded to form a press buckle, which can tightly connect the folded end to the bag body. The limiting groove on the surface of the fixing post and the limiting groove inside the limiting hole are nested with each other to limit lateral and longitudinal displacement and prevent the folded end from loosening. This structure provides stable support for the folded end. Combined with zippers and Velcro, the sealing effect is further enhanced to prevent the seal from failing due to shaking during transportation or storage. At the same time, it ensures convenient folding operation and is not easily damaged by repeated use, thus improving the reliability of the overall structure.

[0018] 4. In summary, this novel zippered antistatic shielding bag, through its structure including folded ends, Velcro, self-sealing grooves, self-sealing ribs, zippers, protective chambers, fixing posts, and limiting holes, achieves a basic seal through the self-sealing grooves and ribs, further reinforced by the zipper. The snap-fit ​​structure of the fixing posts and limiting holes ensures a secure fit between the folded ends and the bag body, while the Velcro enhances connection stability. Multiple seals effectively block dust and prevent items from falling out. The folded ends allow for flexible adjustment of storage volume, and the protective chamber provides cushioning protection as needed. These combined structures ensure both reliable sealing and fixation while maintaining flexibility in use, making it suitable for storage and transportation scenarios and providing comprehensive protection for the contents.

[0023] The following will refer to the appendix in the embodiments of this utility model. Figures 1-3 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0024] Please see Figure 1-3In this embodiment of the utility model, a novel zipper-type antistatic shielding bag includes: a bag body 1, a self-sealing groove 2 inside the bag body 1, a zipper 3 fixedly installed on the surface of the bag body 1, limiting holes 4 on both the left and right sides of the front of the zipper 3, an inner cavity 101 inside the bag body 1, a folding end 102 fixedly installed at the front end of the bag body 1, a self-sealing groove 2 at the bottom inside the inner cavity 101, a self-sealing rib 201 fixedly installed at the upper end inside the inner cavity 101, the self-sealing rib 201 being matched with the self-sealing groove 2, and limiting holes 4 being opened on the upper end of the folding end 102 near the zipper 3. The zipper 3 consists of a chain and a zipper head, and fixing posts 301 are fixedly installed on both its left and right sides. The fixing post 301 is embedded inside the limiting hole 4. The zipper head of the zipper 3 has a hollow pull ring, and the middle of the pull ring is larger than the fixing post 301. When using, place the static-sensitive items (such as electronic components, chips, etc.) to be stored into the inner cavity 101 of the bag body 1, ensuring that the items do not exceed the capacity of the inner cavity and do not obstruct the position of the self-sealing rib 201 and the self-sealing groove 2. Press the self-sealing rib 201 at the upper end of the inner cavity 101 so that it is embedded into the self-sealing groove 2 at the bottom. The engagement of the self-sealing rib and the self-sealing groove achieves a preliminary seal, preventing items from falling or external dust from entering. After confirming that the zipper 3 is in the "fully open" state, pull the zipper head to completely close the chain, and then pick up the zipper 3. The zipper pull, utilizing the characteristic that its pull ring is "hollow and its center is larger than the fixing post 301", is aligned with the fixing post 301 on the side closest to the zipper pull. The pull ring is then placed on the surface of the fixing post 301. At this time, the folding end 102 is folded towards the front end of the bag body 1 (the folding direction is parallel to the surface of the bag body). The folding range is controlled: depending on the height of the item or the required storage space, the folding end 102 is folded to a suitable position (usually folded to cover the upper edge of the bag opening, reducing the exposed area of ​​the inner cavity 101). At this time, the folding end is in contact with the surface of the bag body and presses against the surface of the zipper chain. Then, the limiting hole 4 is pressed, so that the fixing post 301 is embedded inside the limiting hole 4, forming a press-type buckle. After the folding operation is completed, since the bag body 1 is made of materials such as polyethylene or polypropylene that can eliminate static electricity, these materials can conduct away the static electricity generated inside the bag in a timely manner and prevent the accumulation of static electricity. Utilizing the Faraday cage effect, the shielding layer composed of its metal coating or conductive fibers can shield the external electrostatic field and electromagnetic interference outside the bag, while also preventing the static electricity and electromagnetic signals generated by the items inside the bag from leaking to the outside, thereby protecting the static-sensitive components inside the bag from external electromagnetic interference. Therefore, after folding, the shielding layer of the bag body 1 still completely covers the inner cavity 101, and the folding end will not destroy the continuity of the shielding layer, which can continue to isolate external static electricity and electromagnetic interference.

[0025] In this embodiment of the invention, Velcro 103 is fixedly installed on the upper surface of the bag body 1 and the side of the upper end of the folded end 102 near the zipper 3. The two Velcro 103 are bonded to each other and detachably connected. After pressing the limiting hole 4 to insert the fixing post 301 into the limiting hole 4, the Velcro 103 at the upper end of the folded end 102 is pressed to make it completely bonded to the Velcro 103 on the upper surface of the bag body 1. This prevents the folded end from lifting up when the zipper is slightly loose, and at the same time enhances the overall sealing (reduces air circulation and helps shield static electricity).

[0026] In this embodiment of the invention, protective cavities 104 are provided on both the upper and back surfaces of the bag body 1. Compressed sponges are fixedly connected inside the protective cavities 104. Sealing stickers 105 are adhered to the rear side of the outer surface of each protective cavity 104. Air inlets 106 are provided on both the upper and back surfaces of the bag body 1. The sealing stickers 105 are affixed to the surface of the air inlets 106. After a series of sealing operations, the sealing stickers 105 are peeled off from the air inlets 106, exposing them. Outside air enters the protective cavity 104 through the air inlets, triggering the expansion of the compressed sponge (the compressed sponge expands upon contact with air, filling the space of the protective cavity 104). Wait for the compressed sponge to expand naturally until it fits the inner wall of the protective cavity 104 (the expanded sponge is soft and elastic). At this time, the protective cavity 104 on the upper and back surfaces of the bag body 1 forms a "buffer layer" that wraps the items in the inner cavity 101, reducing the impact of external collisions and compression on the items (especially suitable for transportation). Then, re-attach the sealing tape 105 to the air inlet 105 to prevent air from flowing out of the protective cavity 104 due to subsequent compression. If cushioning is not required (such as for static storage or when space needs to be saved), the sealing tape 105 can be kept attached to the air inlet, and the compressed sponge can remain compressed without increasing the thickness of the bag body.

[0027] In this embodiment of the utility model, a first limiting groove 302 is formed on the surface of the fixing post 301, and a second limiting groove 401 is formed inside the limiting hole 4. After the folding end 102 is folded, the limiting hole 4 is pressed so that the fixing post 301 is embedded inside the limiting hole 4. Since the fixing post 301 is slightly larger than the diameter of the limiting hole 4, after the fixing post 301 is embedded inside the limiting hole 4, the first limiting groove 302 is movably connected to the surface of the limiting hole 4, the second limiting groove 401 is nested on the surface of the fixing post 301, and the head end of the fixing post 301 above the first limiting groove 302 is embedded inside the second limiting groove 401, thereby forming a pressing buckle.

[0028] Working principle: Place static-sensitive items (such as electronic components, chips, etc.) into the inner cavity 101 of the bag body 1, ensuring that the items do not exceed the inner cavity capacity and avoid the positions of the self-sealing rib 201 and the self-sealing groove 2 (to avoid obstructing the subsequent sealing structure). Press the self-sealing rib 201 at the upper end of the inner cavity 101 so that it is completely embedded in the self-sealing groove 2 at the bottom. Through the tight interlocking of the self-sealing rib and the self-sealing groove, the inner cavity is initially sealed to prevent items from falling or external dust and impurities from entering. At this time, after confirming that the zipper 3 is in the "fully open" state, pull the zipper head to make the chain completely close (the chain bites the edge of the bag opening to further strengthen the seal). At this time, the fixing posts 301 on the left and right sides of the zipper are exposed, which facilitates subsequent cooperation with the limiting holes. Pick up the zipper head and use its "hollow and..." Taking advantage of the characteristic that the pull tab is larger than the fixing post 301, align the pull tab with the fixing post 301 closest to the zipper head, and place the pull tab on the surface of the fixing post 301 to prevent the pull tab from wobbling later. Fold the folding end 102 towards the front of the bag body 1 (folding direction parallel to the bag body surface). Depending on the height of the items or storage needs, fold the folding end 102 to a suitable position covering the upper edge of the bag opening, ensuring that the folding end is completely in contact with the bag body surface (the folding end presses against the zipper chain surface, further tightening the bag opening). After folding in place, press the limiting hole 4 on the folding end 102 so that the fixing post 301 of the zipper is vertically inserted into the limiting hole 4. Since the fixing post 301 is slightly larger than the diameter of the limiting hole 4, a slight compression will occur during the insertion process: the limiting groove 30 on the surface of the fixing post 301... 2. The limiting groove 401 inside the limiting hole 4 is naturally nested in the surface of the fixing post 301, and the head end of the fixing post 301 is embedded in the limiting groove 401, forming a "concave-convex interlocking" press buckle (the cooperation between the limiting groove 1 and the limiting groove 2 restricts the lateral and longitudinal displacement of the fixing post). Then, press the Velcro 103 on the upper end of the folding end 102 to make it completely bonded to the Velcro 103 on the upper surface of the bag body 1. The adhesive force of the Velcro further strengthens the folding end, preventing the folding end from lifting when the zipper is slightly loose, and at the same time enhances the overall sealing (reducing air circulation and helping to improve the anti-static effect). If collision protection is required (such as in the transportation process), tear off the sealing tape 105 on the upper surface of the bag body 1 and the back protective cavity 104 to allow the contents to enter. With the vent 106 exposed, outside air enters the protective cavity 104 through the air inlet, triggering the expansion of the internal compressed sponge until it adheres to the inner wall of the protective cavity (forming a soft and elastic cushioning layer to wrap the contents and reduce impact). After expansion, the sealing tape 105 is reattached to the surface of the air inlet 106 to prevent subsequent compression from causing air to leak out of the protective cavity (ensuring continued cushioning effect). For static storage or to save space, the sealing tape 105 remains attached to the air inlet 106, and the compressed sponge remains compressed without increasing the bag's thickness (avoiding additional storage space). After folding and securing, the shielding layer of the bag 1 (containing a metal coating or conductive fibers) still completely wraps the inner cavity 101: the inner polyethylene / polypropylene material can promptly dissipate static electricity inside the bag.To prevent static electricity buildup, the outer shielding layer isolates external electrostatic fields and electromagnetic interference through the Faraday cage effect, while also preventing the leakage of static signals from inside the bag. Folding at the ends and securing with clips will not disrupt the continuity of the shielding layer, ensuring the items are protected from static electricity and electromagnetic interference throughout the entire process. This ensures that static-sensitive items are not damaged during storage and transportation, balancing safety and practicality.
