Description

Technical Field

[0001] This utility model relates to the field of packaging technology, specifically to a shockproof heat-pressed bag. Background Technology

[0002] Heat-pressed bags are packaging products made through a heat-pressing process. They are primarily made of materials such as PVC, TPU, and EVA, and are manufactured through a combination of machine and manual pressing, followed by manual edge tearing, cleaning, and packaging. Heat-pressed bags are widely used in industries such as daily necessities, rain gear, cosmetics, toys, stationery, gifts, food, clothing, and handbags.

[0003] Existing bags rely solely on their own material for shock protection and lack specialized cushioning structures, resulting in insufficient protection for the contents, especially fragile items. When the bag is bumped or dropped, the fragile items inside are easily damaged.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a shockproof heat-pressing bag. Utility Model Content

[0005] The purpose of this invention is to provide a shockproof heat-pressed bag to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shockproof heat-pressed bag, comprising a bag body and a handle, wherein a bag flap is sewn onto the outer edge of the bag body, and a chain is provided at the edge of the opening of the bag body and the edge of the bag flap, wherein a first pull head and a second pull head are installed on the chain, the handle is sewn onto the top two sides of the bag body, and an airbag strip is provided on the inner sidewall of the bag body and the bag flap, wherein the outer surface of the airbag strip is covered with a polyimide protective film.

[0007] Furthermore, both the bag body and the bag cover are made of EVA material and formed by hot pressing, and the thickness of the bag body and the bag cover is 5mm.

[0008] Furthermore, a first hook is installed on the left side of the handle, and a second hook is installed on the right side of the handle.

[0009] Furthermore, the second hook has a second metal latch externally connected to it, and the first hook has a first metal latch externally connected to it.

[0010] Furthermore, a shoulder strap is provided between the first metal buckle and the second metal buckle, and a D-ring buckle is installed on the shoulder strap.

[0011] Furthermore, the chain belt is provided with two belts, and both the first pull head and the second pull head are adapted to the chain belt.

[0012] Furthermore, the edges of the bag body and the bag flap are both arc-shaped, and the first hook and the second hook are symmetrically distributed about the vertical central axis of the bag body.

[0013] Furthermore, both the first and second metal latches are made of zinc alloy, and both the first and second metal latches have a load-bearing capacity of more than 5 kg.

[0014] This utility model provides a shockproof heat-press bag, which has the following beneficial effects: 1. The shoulder strap of this utility model is connected to the first hook and the second hook respectively through the first metal buckle and the second metal buckle. The detachable design allows users to flexibly choose to carry it by hand or over the shoulder according to their needs, adapting to different travel scenarios. The D-ring buckle on the shoulder strap can realize the length adjustment, which can adapt to the carrying needs of users of different heights. The adjustment process is simple and smooth and can be completed without tools, greatly improving the portability and practicality of the bag.

[0015] 2. The edges of the bag body and flap of this utility model are all rounded, avoiding the presence of sharp corners. This not only prevents scratching items when they are placed inside, but also disperses the force when the bag body is hit, further improving the drop protection effect. The airbag strip is set in the inner wall of the bag body and flap, forming a fully enclosed buffer barrier. When the bag is hit by an external impact or dropped, it can absorb the impact force from the side of the items in all directions, avoiding the impact force from acting directly on the items inside the bag. This greatly reduces the risk of damage to items due to excessive local force. The polyimide protective film can effectively prevent sharp items inside the bag from puncturing the airbag strip, protecting the integrity of the airbag strip. Attached Figure Description

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] like Figures 1 to 5 As shown, a shockproof heat-pressed bag includes a bag body 1 and a handle 6. The handle 6 is sewn to the top of both sides of the bag body 1. A first hook 7 is installed on the left side of the handle 6, and a second hook 8 is installed on the right side of the handle 6. A second metal buckle 10 is connected to the outside of the second hook 8. The edges of the bag body 1 and the bag flap 5 are both arc-shaped. The first hook 7 and the second hook 8 are symmetrically distributed about the vertical central axis of the bag body 1. A first metal buckle 9 is connected to the outside of the first hook 7. A shoulder strap 11 is provided between the first metal buckle 9 and the second metal buckle 10. A D-ring buckle 12 is installed on the shoulder strap 11. Both the first metal buckle 9 and the second metal buckle 10 are made of zinc alloy, and the load-bearing capacity of both the first metal buckle 9 and the second metal buckle 10 is greater than 5 kg.

[0020] The specific operation is as follows: the shoulder strap 11 is connected to the first hook 7 and the second hook 8 respectively through the first metal buckle 9 and the second metal buckle 10. The detachable design allows users to flexibly choose to carry it by hand or over the shoulder according to their needs, adapting to different travel scenarios. The D-ring buckle 12 on the shoulder strap 11 can be adjusted in length to accommodate the carrying needs of users of different heights. The adjustment process is simple and smooth and can be completed without tools, greatly improving the portability and practicality of the bag.

[0021] like Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, a flap 5 is sewn onto the outer edge of the bag body 1, and a chain strap 2 is provided at the edge of the opening of the bag body 1 and the edge of the flap 5. A first zipper pull 3 and a second zipper pull 4 are installed on the chain strap 2. The bag body 1 and the flap 5 are both made of EVA material and formed by hot pressing. The thickness of the bag body 1 and the flap 5 is 5mm. There are two chains 2, and the first zipper pull 3 and the second zipper pull 4 are both adapted to the chain strap 2. An airbag strip 13 is provided on the inner side wall of the bag body 1 and the flap 5, and the outer surface of the airbag strip 13 is covered with a polyimide protective film 14.

[0022] The specific operation is as follows: the edges of the bag body 1 and the bag cover 5 are both rounded to avoid sharp corners. This prevents items from being scratched when placed inside and also disperses the force when the bag body 1 is hit, further improving the drop protection effect. The airbag strip 7 is set on the inner wall of the bag body 1 and the bag cover 5 to form a fully enclosed buffer barrier. When the bag is hit by an external impact or dropped, it can absorb the impact force from the side of the item from all directions, avoiding the impact force from acting directly on the item inside the bag. This greatly reduces the risk of damage to the item due to excessive local force. The polyimide protective film 11 can effectively prevent sharp items inside the bag from puncturing the airbag strip 7 and protect the integrity of the airbag strip 7.

[0023] In summary, when using this portable shockproof heat-pressed bag, first hold the first zipper 3 and the second zipper 4 and pull it to both sides of the bag body 1. During the pulling process, the chain teeth of the chain 2 will separate, causing the bag cover 5 to gradually open from the bag body 1. When the first zipper 3 and the second zipper 4 are pulled to the end of the chain 2, the bag cover 5 can be fully opened, revealing the internal storage space of the bag body 1, which is convenient for placing items. The bag body 1 and the bag flap 5 are made of 5mm thick EVA material through hot pressing. EVA material itself has good elasticity and cushioning performance, which can absorb most of the impact force when it is hit or dropped, reducing the impact on the internal items. Moreover, the edges are designed with rounded transitions, which not only prevents the items from being scratched by sharp corners when placed, but also disperses the force when the bag body 1 is hit. The airbag strip 7 is set on the inner wall of the bag body 1 and the bag flap 5 to form a fully enclosed cushioning barrier. When the bag is hit by external impact or dropped, it can bear the impact force from the side of the items in all directions, avoiding the impact force from directly acting on the items inside the bag, and greatly reducing the risk of damage to the items due to excessive local force. The polyimide protective film 11 can effectively prevent sharp items inside the bag from puncturing the airbag strip 7, protecting the integrity of the airbag strip 7. After placing the items, close the bag flap 5 on the bag body 1, and then pull the first pull head 3 and the second pull head 4 towards the middle, so that the teeth of the two chain belts 2 mesh with each other until the bag flap 5 and the bag body 1 are closed. When carrying for short distances, you can directly hold the handle 6. If you choose to carry it on your shoulder, you can fasten the first metal buckle 9 to the first hook 7 and the second metal buckle 10 to the second hook 8. Then, you can adjust the length of the shoulder strap 11 by using the D-ring buckle 12 to accommodate users of different heights and carrying habits, making the shoulder carrying process more comfortable and greatly improving the portability of the bag, meeting the carrying needs in different scenarios.
