Description

Technical Field

[0001] This utility model relates to the field of air column bag technology, specifically a shockproof air column bag for cold chain processing of fruits and vegetables. Background Technology

[0002] Air column bags, also known as cushioning air column bags, inflatable bags, bubble column bags, or columnar inflatable bags, are a new type of packaging material in the 21st century that uses natural air to fill the packaging. Air column bags are needed for shockproof packaging during the cold chain transportation of fruits and vegetables.

[0003] For example, announcement number CN210654489U (named "Anti-vibration Air Column Bag for Cold Chain of Fruits and Vegetables") includes a film packaging plate. A packaging air column is installed on one side of the film packaging plate, and a second buckle is installed at the bottom of the packaging air column. A flat plate is installed at one end of the second buckle, and a retaining ball is installed at the other end. A second retaining seat is installed on one side of the retaining ball. A sponge board is installed on one side of the packaging air column, and connecting tape is installed on one side of the sponge board. A retaining plate is installed at one end of the connecting tape, and a retaining groove is formed at the bottom of the retaining plate. A permeable surface is formed on the surface of the sponge board. The air column bag is made into a plate shape using buckles and mounting brackets. This plate-shaped air column bag is then attached to the outer wall of the item to wrap it. During packaging, the item will not scratch the air column bag, ensuring its integrity. This makes the air column bag more reliable and the item safer during transportation. Two sponge boards are installed on the inner wall of the air column bag. When the item comes into contact with the sponge boards, even if the air column bag falls to the ground and experiences strong bumps, it will not affect the contents inside, protecting the item and preventing accidental damage to the item during transportation.

[0004] The aforementioned air column bags use a ring-shaped structure to provide shockproof packaging for items during use. However, the lack of effective sealing and fixation at both ends of the air column bags during use makes it easy for items to fall out of the air column bags during transportation. To address this, we provide a shockproof air column bag for cold chain logistics of fruits and vegetables. Utility Model Content

[0005] The purpose of this utility model is to provide a shockproof air column bag for cold chain of fruits and vegetables, so as to solve the problem mentioned in the background art that the existing air column bags use a ring-shaped structure to pack items for shockproof packaging, but the ends of the air column bags lack effective sealing and fixation, which makes it easy for items to fall out of the air column bag during transportation.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a shockproof air column bag for cold chain of fruits and vegetables, comprising an encircling air column layer, with end cap air column layers installed at both ends of the encircling air column layer;

[0007] Also includes:

[0008] The end bag strip is integrally formed at both ends of the circumferential air column layer, and the end bag strip is provided with synchronous air holes inside;

[0009] A plastic outer ring is fixed to the outer wall of the end cap air column layer by a nail-free adhesive, and the plastic outer ring has a vent hole inside, the diameter of which is equal to the diameter of the synchronous air hole.

[0010] A separating air column layer is installed in the circumferential air column layer, and a plastic liner is fixed to the outer wall of the separating air column layer by nail-free adhesive.

[0011] Preferably, a male hook and loop fastener and a female hook and loop fastener are respectively provided on the two sides of the circumferential air column layer, and the male hook and loop fastener and the female hook and loop fastener are fixedly connected to the two sides of the circumferential air column layer by nail-free adhesive.

[0012] Preferably, the ring-shaped air column layer is fixedly connected by a female hook and loop fastener at both sides, and the female hook and loop fasteners are of equal size.

[0013] Preferably, both ends of the end bag strip are provided with extension bag strips, and both extension bag strips are integral with the end bag strip.

[0014] Preferably, the outer walls of the plastic liner are integrally formed with matching corner clips, and the separating air column layer is connected to the column contour of the circumferential air column layer through the matching corner clips.

[0015] Preferably, the end bag strips at both ends of the annular air column layer are fixedly connected to the outer plastic ring outside the end cap air column layer by tape.

[0016] Preferably, there are twelve synchronizing vents, and the spacing between two adjacent synchronizing vents is equal.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention installs the end cap air column layer onto both ends of the ring-shaped air column layer. During installation, an extension strip wraps around the outer plastic ring and is secured with tape, achieving a sealed and fixed end to the air column bag. This improves the shockproof protection for fruits and vegetables. When the packaging needs to be opened, simply pull the extension strip to easily tear it open along with the tape. During use, the plastic liner and outer plastic ring act as a skeleton structure to support the main structure of the air column bag, improving the overall strength of the packaging structure. This overcomes the problem that existing air column bags, while using a ring-shaped structure for shockproof packaging, lack effective sealing and fixation at both ends, leading to items easily falling out of the air column bag during transportation.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-4 An embodiment of this utility model is provided: a shockproof air column bag for cold chain of fruits and vegetables, including a ring-shaped air column layer 1, and end cap air column layers 6 are installed at both ends of the ring-shaped air column layer 1.

[0026] Also includes:

[0027] The end bag strip 2 is integrally formed and set at both ends of the circumferential air column layer 1, and the end bag strip 2 is provided with synchronous air holes 9 inside;

[0028] The plastic outer ring 7 is fixed to the outer wall of the end cap air column layer 6 by nail-free adhesive, and the plastic outer ring 7 has a vent hole 8 inside, the diameter of the vent hole 8 being equal to the diameter of the synchronous air hole 9.

[0029] The separating air column layer 4 is installed around the air column layer 1, and a plastic liner 5 is fixed to the outer wall of the separating air column layer 4 with nail-free adhesive.

[0030] In use, the ring-shaped air column layer 1 is wrapped around the outside of the fruit and vegetables. When different fruits and vegetables need to be packaged, the separating air column layer 4 is installed inside the ring-shaped air column layer 1 for separate packaging. Then, the end cap air column layer 6 is installed at both ends of the ring-shaped air column layer 1. During installation, the extension bag strip 3 is wrapped around the plastic outer ring 7 and fixed with tape. When fixing, depending on whether the fruit and vegetables need to be breathable, the ventilation holes 8 and synchronous air holes 9 are matched. When breathability is not required, the ventilation holes 8 and synchronous air holes 9 are staggered before fixing the tape. When breathability is required, the ventilation holes 8 and synchronous air holes 9 are matched before fixing the tape. This achieves the purpose of sealing and fixing both ends of the air column bag, improving the shockproof protection effect for the fruit and vegetables. When the packaging needs to be opened, simply pull the extension bag strip 3 to easily tear it open along with the tape. During the packaging process, the plastic liner 5 and the plastic outer ring 7 act as a skeleton structure to support the main structure of the air column bag, preventing the air column bag from deforming too much and causing damage to the fruit and vegetables.

The male hook and loop fasteners 10 and female hook and loop fasteners 11 are fixedly connected to the two sides of the circumferential air column layer 1 using adhesive. The male hook and loop fasteners 10 and female hook and loop fasteners 11 on both sides of the circumferential air column layer 1 facilitate the fixing and adhesion of the circumferential air column layer 1 after it is wrapped. Please refer to [link / reference]. Figure 1 and Figure 2 The annular air column layer 1 is fixedly connected by a female hook and loop fastener 10 and a female hook and loop fastener 11 at both sides. The female hook and loop fastener 10 and the female hook and loop fastener 11 are of equal size. Please refer to [link / reference]. Figure 1 Both ends of the end bag strip 2 are provided with extension bag strips 3. Both extension bag strips 3 are integral with the end bag strip 2. The extension bag strips 3 at both ends of the end bag strip 2 facilitate tearing open the extension bag strips 3 to separate the plastic outer ring 7 from the extension bag strips 3. Please refer to [link / reference]. Figure 3 The plastic outer liner 5 has integrally formed matching corner brackets 12 on its four outer walls. The separating air column layer 4 is connected to the cylindrical contour of the circumferential air column layer 1 via the matching corner brackets 12.
