Description

Technical Field

[0001] This utility model relates to the field of product packaging protection technology, specifically to a B-shaped air column bag and a packaging box having the same. Background Technology

[0002] In the existing technology, tin can milk powder is mostly transported and packaged by placing corrugated paper partitions inside corrugated cardboard boxes (such as 6 cans / box or 8 cans / box). However, there is a problem that tin cans are easily damaged by collisions. For example, the logistics and transportation process is complicated. When the cardboard box is accidentally dropped, even with corrugated paper partitions for cushioning, the protection performance is insufficient, and dented or damaged cans often occur, affecting the product's appearance and sales.

[0003] Currently, air column bags are used for cushioning, but these bags are mostly single "L" or "U" shaped bags that do not fit well with cylindrical milk powder cans and cannot fit completely. They are also difficult to place properly inside the box, resulting in insufficient overall stability of the packaging inside the box and underutilization of space. Therefore, there is an urgent need to design a new type of air column bag to solve the problems of the existing technology. Utility Model Content

[0004] The purpose of this invention is to provide an irregularly shaped air column bag structure that tightly wraps a cylindrical iron can with an air column cavity shaped like the letter B, which can effectively improve the cushioning and support performance.

[0005] To achieve the above objectives, this utility model is specifically implemented through the following technical solution:

[0006] A B-shaped air column bag includes an air column bag body formed by a single-piece air column roll material. The air column bag body includes a first bag body and a second bag body symmetrically arranged in a B-shape. The first bag body and the second bag body are vertically connected. A support part is provided at the connection between the first bag body, the second bag body and the middle part of the air column bag body. The air column bag is provided with at least one inflation port.

[0007] Based on the above scheme, the two ends of the air column roll are bent to the same side and then hot-pressed to be fixed in the middle of the air column roll to form a B-shaped air column bag body.

[0008] Based on the above scheme, the material of the air column bag body is polyethylene or polyamide.

[0009] Based on the above scheme, the support part is formed by multiple heat-sealed nodes arranged vertically in a straight line.

[0010] Based on the above scheme, the inflation port is located at the connection between the first bag body or the second bag body and the air column bag body.

[0011] Based on the above scheme, the length of the air column roll is 80-180cm.

[0012] Based on the above scheme, the height of the first bag and the second bag is 20-40cm.

[0013] This utility model also provides a packaging box having any of the above-described B-shaped air column bags, including a box body and at least two sets of B-shaped air column bags, wherein the B-shaped air column bags are arranged vertically inside the box body, and the depth of the box body is greater than the height of the B-shaped air column bags.

[0014] Based on the above scheme, the number of B-shaped air column bags is 3, and they are arranged in the same direction inside the box.

[0015] The main technical solution of this utility model is a cylindrical iron can milk powder design. Through the B-shaped air column cavity, the iron can is customized and tightly wrapped, improving the cushioning performance and reducing the rate of can collapse after collision. The B-shaped air column bag does not require complicated shaping and assembly actions during use, saving operation time and increasing production efficiency. Attached Figure Description

[0022] like Figure 1 and Figure 2 As shown, the present invention discloses a B-shaped air column bag, comprising an air column bag body 1 formed by a single-piece air column roll material. The air column bag body 1 includes a first bag body 11 and a second bag body 12 arranged symmetrically in a B-shape. The first bag body 11 and the second bag body 12 are vertically connected. A support part 13 is provided at the connection between the first bag body 11 and the second bag body 12 and the middle part of the air column bag body 1. The air column bag is provided with at least one inflation port 14.

[0023] The air column roll material can be made of high-strength PE (polyethylene) or PA (polyamide, nylon) to ensure the flexibility and puncture resistance of each air column. The production and processing adopts co-extrusion process and is pressed by heat sealing equipment to form an airtight inflatable air column, which is then made into the "B" shaped air column bag of this utility model. After the air column bag is inflated, it automatically locks in air and does not leak.

[0024] In a specific embodiment, the two ends of the air column roll are bent to the same side and then hot-pressed to the middle of the air column roll to form a B-shaped air column bag body 1.
