Description

Technical Field

[0001] This utility model relates to the field of nonwoven packaging bag technology, and in particular to a moisture-proof nonwoven packaging bag. Background Technology

[0002] Non-woven fabric packaging bags, also known as non-woven eco-friendly bags, are packaging bags made from non-woven fabric materials. Non-woven fabric (also called non-woven textile) is not formed by interlacing warp and weft threads in traditional textile processes; instead, it is a fabric formed by directly bonding or combining fibers through physical or chemical methods. Non-woven fabric packaging bags are commonly used to store and carry various items, including electronic products, food, and clothing. These items are easily damaged in humid environments. For example, electronic products may short-circuit or be damaged due to moisture, food may spoil due to dampness, and clothing may be damaged by mold. Therefore, moisture protection is an important means for non-woven fabric packaging bags to protect the items inside.

[0003] Existing non-woven packaging bags typically prevent external moisture from entering the bag by placing a desiccant inside or adding a moisture-proof layer at the bottom. For example, utility model patent application number 202021007788.6 discloses a non-woven packaging bag with moisture-proof function. The moisture-proof layer, connected to a buckle inside the bag via a connecting ring, enhances the moisture-proof effect at the bottom of the bag during use, thus protecting the contents and preventing moisture damage when the bag is placed on the ground.

[0004] While the aforementioned non-woven fabric packaging bag features a moisture-proof layer that enhances the moisture-proof effect at the bottom of the bag, preventing it from being affected by moisture when placed on the ground, the open top of the bag allows external moisture to enter the non-woven fabric during storage, especially in humid environments, causing the stored items to become damp.

[0005] Therefore, it is necessary to develop a moisture-proof non-woven packaging bag to address the aforementioned shortcomings. Utility Model Content

[0006] The purpose of this invention is to provide a moisture-proof non-woven packaging bag that can seal the top of the non-woven packaging bag to prevent external humid air from entering the non-woven packaging bag and improve the moisture-proof effect.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model discloses a moisture-proof non-woven packaging bag, comprising a main body of the bag, with folded edges fixedly connected to both sides of the main body, and a vertical fold line set in the middle of each of the two folded edges. A first hook-and-loop fastener and a first loop fastener are fixedly connected to two opposite side walls of the main body of the bag, respectively. Sealing elements are provided at both ends of the main body of the bag, each including a pull cord and a second fastener. First threading holes are respectively opened at the top ends of both sides of the main body of the bag, and two second threading holes symmetrical about the fold lines are opened on each folded edge. One end of the pull cord is fixedly connected to a limiting block, and the other end of the pull cord passes sequentially through the first threading hole and the second threading hole from one end of the main body of the bag. The second fastener is fixedly connected to the outer side wall of the main body of the bag and located directly above the first threading hole, with the second fastener located on the same side of the pull cord away from the limiting block.

[0009] Furthermore, handles are fixedly connected to both sides of the top of the main body of the packaging bag, and the ends of the two pull ropes away from the limiting block are fixedly connected to the handles on the same side.

[0010] Furthermore, the two limiting blocks are located on different sides of the main body of the packaging bag.

[0011] Furthermore, each of the two handles is fixedly connected to a grip plate at its top, and a matching male buckle and female buckle are fixedly connected to the two side walls facing each other on the grip plate.

[0012] Furthermore, the gripping plate is specifically made of silicone material, and both gripping plates have a wavy gripping part at their bottom ends.

[0013] Furthermore, both the first and second threading holes are fixed with perforated rings.

[0014] Compared with the prior art, the beneficial technical effects of this utility model are as follows:

[0015] This invention utilizes a first hook-and-loop fastener and a first loop fastener to seal the center of the top opening of the packaging bag. A pull cord and a second fastener are used; one end of the pull cord is fixedly connected to a limiting block, and the other end passes through the threading holes on the main body and folded edge of the packaging bag, finally securing it to the outer wall of the bag via the second fastener. This seals both ends of the top opening, further enhancing the bag's airtightness and preventing humid air from entering the non-woven packaging bag, thus improving moisture protection. Furthermore, the tightness of the pull cord can be adjusted according to the user's needs, thereby controlling the degree to which the top opening of the packaging bag can be opened or closed.

[0016] In addition, a grip plate is provided at the top of the handle, with matching male and female buckles. This allows the two grip plates to interlock, further enhancing the portability and stability of the packaging bag. The grip plates are made of silicone and have a wavy grip at the bottom, improving grip comfort and stability. Attached Figure Description

[0022] The core of this utility model is to provide a moisture-proof non-woven packaging bag that can seal the top of the non-woven packaging bag to prevent external humid air from entering the non-woven packaging bag and improve the moisture-proof effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] In one specific implementation, such as Figures 1-3 As shown, a moisture-proof non-woven packaging bag includes a main body 1. Both sides of the main body 1 are sewn together with folded edges 2. A vertical crease 3, formed by embossing, is located between the two folded edges 2. On opposite side walls of the main body 1, a first hook-and-loop fastener 4 and a first loop fastener 5 are sewn or glued together. Sealing elements are located at both ends of the main body 1, including a pull cord 6 and a second fastener 7. The top ends of both sides of the main body 1 are... A first threading hole 8 is provided, and two second threading holes 9 are provided on the folded edge 2 symmetrical about the fold line 3. One end of the pull cord 6 is fixedly connected to a limiting block 10 by sewing, knotting, or gluing. The diameter of the limiting block 10 is larger than the diameter of the first threading hole 8. The other end of the pull cord 6 passes through the first threading hole 8 and the second threading hole 9 sequentially from one end of the packaging bag body 1. A second hook and loop fastener 7 is fixedly connected to the outer wall of the packaging bag body 1 and is located directly above the first threading hole 8. The second hook and loop fastener 7 is located on the same side as the pull cord 6 away from the limiting block 10. The hook side of the second hook and loop fastener 7 is sewn or glued to the outer wall of the packaging bag body 1, and the rough side of the second hook and loop fastener 7 is glued to the hook side of the second hook and loop fastener 7.

[0026] The first hook-and-loop fastener 4 and the first loop fastener 5 are used to seal the middle of the top opening of the packaging bag body 1. A pull cord 6 and a second hook-and-loop fastener 7 are used; one end of the pull cord 6 is fixedly connected to a limiting block 10, and the other end passes through the first thread hole 8 and the second thread hole 9, finally being fixed to the outer wall of the packaging bag body 1 by the second hook-and-loop fastener 7. This seals both ends of the top opening of the packaging bag, further enhancing its airtightness. Furthermore, the tightness of the pull cord 6 can be adjusted according to the user's needs, thereby controlling the degree of opening and closing of the top opening of the packaging bag.

[0027] In one specific embodiment, handles 11 are fixedly connected to both sides of the top of the main body 1 of the packaging bag by sewing or gluing, and the ends of the two pull ropes 6 away from the limiting block 10 are fixedly connected to the handles 11 on the same side by sewing, gluing or knotting.

[0028] By fixing the rope 6 to the handle 11, the load-bearing capacity of the handle 11 can be enhanced.

[0029] Specifically, the two limiting blocks 10 are located on different sides of the main body 1 of the packaging bag.

[0030] This design ensures that the tension of the two pull ropes 6 is evenly distributed, preventing the main body 1 of the packaging bag from deforming during transport.

[0031] Specifically, each of the two handles 11 has a gripping plate 12 fixedly connected to its top end by adhesive, and a matching male buckle 13 and female buckle 14 are fixedly connected to the two side walls opposite to the gripping plate 12.

[0032] The gripping plate 12, along with the male buckle 13 and female buckle 14, allows the two gripping plates 12 to interlock, further enhancing the portability and stability of the packaging bag.

[0033] Specifically, the grip plates 12 are made of silicone, and both grip plates 12 have wavy grip portions 15 at their bottom ends. This improves grip comfort and stability.

[0034] In one specific embodiment, a hole ring 16 is fixed to both the first thread hole 8 and the second thread hole 9 by means of sewing, gluing or inlaying.

[0035] By setting the perforated ring 16, the friction between the pull rope 6 and the first threading hole 8 and the second threading hole 9 can be reduced, preventing the first threading hole 8 and the second threading hole 9 from breaking and extending the service life of the packaging bag.

[0036] The working principle of this utility model is as follows: When using this moisture-proof non-woven packaging bag, firstly, the item is placed inside the main body 1 of the packaging bag. Then, the first hook-and-loop fastener 4 and the first loop fastener 5 at the top center of the main body 1 of the packaging bag are glued together to achieve a preliminary seal of the main body 1 of the packaging bag. Next, by tightening the pull cords 6 on both sides of the main body 1 of the packaging bag, the pull cords 6 are fixed between the hook and loop sides of the second loop fastener 7. The pull cords 6 are fixed by the adhesion between the hook and loop sides of the second loop fastener 7, thereby making the folded edge 2 fit with the main body 1 of the packaging bag, thus sealing both ends of the main body 1 of the packaging bag. This effectively prevents external moisture from entering the main body 1 of the packaging bag and improves the moisture-proof effect of the non-woven fabric.
