Description

Technical Field

[0001] This utility model relates to the field of air column bag technology, specifically an anti-compression express packaging air column bag. Background Technology

[0002] In express delivery, squeezing and impact are the main causes of damage to goods. Air column bags have become the mainstream packaging material due to their lightweight and good cushioning properties. However, existing express packaging air column bags have poor compression resistance in actual use, which can easily lead to damage to the products inside the air column bag due to vehicle shaking or external heavy objects squeezing it. Therefore, we propose a compression-resistant express packaging air column bag. Utility Model Content

[0003] The purpose of this utility model is to provide a compression-resistant express packaging air column bag to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a compression-resistant express packaging air column bag, including a base, an air column bag body fixedly connected to the top of the base, reinforcing sleeves provided at the bottom, top, and outer surface of the air column bag body, a slot provided at the top of the reinforcing sleeve, a locking block engaged in the inner cavity of the slot, a movable cover fixedly connected to the top of the locking block, a reserved groove provided at the middle of the top of the movable cover, fixing grooves provided on the front and rear sides of the top of the locking block, a fixing block fixedly connected to the top of the base, an elastic band fixedly connected to the top of the fixing block, and the surface of the elastic band contacting the inner cavity of the fixing groove.

[0005] Preferably, the base includes a natural rubber layer, a butadiene rubber layer, and an ethylene propylene rubber layer, which are arranged sequentially.

[0006] Preferably, the air column bag body includes a polypropylene layer, a polyethylene layer, and a nylon layer, wherein the polypropylene layer, polyethylene layer, and nylon layer are arranged sequentially.

[0007] Preferably, the thickness of the polypropylene layer and the polyethylene layer is 0.21cm-0.23cm, and the thickness of the nylon layer is 0.22cm-0.24cm.

[0008] Preferably, the thickness of the natural rubber layer and the butadiene rubber layer is 0.18cm-0.21cm, and the thickness of the ethylene propylene rubber layer is 0.11cm-0.18cm.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model features reinforcing hoops on the bottom, top, and outer surface of the air column bag body. These hoops enhance the overall structural strength of the air column bag, effectively resisting external compression and protecting the contents from damage. The base employs a structure with layers of natural rubber, butadiene rubber, and ethylene propylene rubber arranged sequentially. These rubber materials possess excellent elasticity and cushioning properties, further enhancing the compression resistance of the bottom of the air column bag and reducing the impact on the contents when the bottom is compressed. The air column bag body is composed of a polypropylene layer, a polyethylene layer, and a nylon layer. Polypropylene and polyethylene possess a certain degree of flexibility and strength, while the nylon layer increases the air column bag's wear resistance and tear resistance, collectively improving the overall compression resistance of the air column bag.

[0010] 2. This utility model features a movable cover that engages with the reinforcing sleeve via a locking block, facilitating the opening and closing of the air column bag. Simultaneously, the elastic band, in conjunction with the fixing groove, secures the movable cover when closed, preventing accidental opening. To open, simply untie the elastic band; operation is simple and convenient. A pre-drilled groove at the top of the movable cover allows users to easily grip and open it with their fingers.

[0015] Please see Figures 1-4 The following technical solution is provided, specifically disclosing: an anti-compression express packaging air column bag, including a base 1, an air column bag body 5 fixedly connected to the top of the base 1, a reinforcing sleeve 4 provided at the bottom, top and outer surface of the air column bag body 5, a slot 9 opened at the top of the reinforcing sleeve 4, a locking block 10 locked in the inner cavity of the slot 9, a movable cover 6 fixedly connected to the top of the locking block 10, a reserved groove 7 opened at the middle of the top of the movable cover 6, fixing grooves 8 opened on the front and rear sides of the top of the locking block 10, a fixing block 2 fixedly connected to the top of the base 1, an elastic band 3 fixedly connected to the top of the fixing block 2, and the surface of the elastic band 3 contacting the inner cavity of the fixing groove 8; In practical use, reinforcing hoops 4 are installed on the bottom, top, and outer surface of the air column bag body 5. These reinforcing hoops enhance the overall structural strength of the air column bag, effectively resisting external compression and protecting the contents from damage. The base 1 adopts a structure with a natural rubber layer 101, a butadiene rubber layer 102, and an ethylene propylene rubber layer 103 arranged sequentially. These rubber materials have good elasticity and cushioning properties, further enhancing the compression resistance of the bottom of the air column bag and reducing the impact on the contents when the bottom is compressed. The air column bag body 5 is composed of a polypropylene layer 501, a polyethylene layer 502, and a nylon layer 503. Polypropylene and polyethylene have certain flexibility and strength, while the nylon layer increases the wear resistance and tear resistance of the air column bag, collectively improving the overall compression resistance of the air column bag. Example

[0016] Please see Figure 1 and Figure 2The following technical solution is provided, specifically disclosed: The base 1 includes a natural rubber layer 101, a butadiene rubber layer 102, and an ethylene propylene rubber layer 103, which are arranged sequentially; the air column bag body 5 includes a polypropylene layer 501, a polyethylene layer 502, and a nylon layer 503, which are arranged sequentially; the thickness of the polypropylene layer 501 and the polyethylene layer 502 is 0.21cm-0.23cm; the thickness of the nylon layer 503 is 0.22cm-0.24cm; the thickness of the natural rubber layer 101 and the butadiene rubber layer 102 is 0.18cm-0.21cm; and the thickness of the ethylene propylene rubber layer 103 is 0.11cm-0.18cm. In actual use, the movable cover 6 engages with the slot 9 of the reinforcing sleeve 4 via the locking block 10, facilitating the opening and closing of the air column bag. Simultaneously, the elastic band 3 cooperates with the fixing groove 8 to secure the movable cover when closed, preventing accidental opening; to open it, simply untie the elastic band, making operation simple and convenient. The pre-drilled groove 7 at the top of the movable cover allows users to easily open it by gripping the cover with their fingers.

[0017] In use: Untie the elastic band 3 and remove it from the fixing groove 8. Then, use your fingers to pry open the movable cover 6 through the reserved groove 7 and lift it upwards to disengage the locking block 10 from the locking groove 9, thus opening the air column bag. Place the items to be packaged into the air column bag body 5. Align the locking block 10 of the movable cover 6 with the locking groove 9 of the reinforcing sleeve 4 and press the movable cover downwards to engage the locking block. Then, wrap the elastic band 3 around the movable cover and embed it into the fixing groove 8 to secure the movable cover and prevent it from opening accidentally during transportation. During express delivery, when the air column bag is subjected to external pressure, the reinforcing sleeve 4 first bears part of the pressure, dispersing the pressure and enhancing the overall structural stability of the air column bag. The polypropylene layer 501, polyethylene layer 502, and nylon layer 503 of the air column bag body 5 work together to resist compression and friction, protecting the internal items. Meanwhile, the natural rubber layer 101, butadiene rubber layer 102, and ethylene propylene rubber layer 103 of the base 1 provide elasticity and cushioning, reducing the impact on the item when the bottom is squeezed, and ensuring the safety of the item.
