Preferably, the outer cushion layer port and the inner cushion layer port share the same gas port.

Preferably, preferably, the edges of the outer buffer layer opening, the inner buffer layer opening and the gas filling opening share the same edge.

Preferably, the aperture of the inner buffer layer has a taper.

Preferably, the inner buffer layer is wide on one side of the inflation port and narrow on the other side.

Preferably, the inflation port includes but is not limited to a two-port one-way air valve.

Preferably, the inflatable protective bag adopts a PA+PE composite film.

Compared with the prior art, the utility model has the following advantages:

1. The utility model mainly solves the problems that the bottle neck of similar red wine is prone to breakage and damage, and a large number of buffer materials are abused, but the buffering and protection effects are not good.

2. The present invention can effectively solve the problem that the bottle neck of red wine is easily broken during transportation by combining the internal buffer layer (internal airbag after inflation) with the external buffer layer (outer integral airbag) on the bottle neck.

3. The utility model utilizes inflation between the film and the film to increase the buffer volume, thereby achieving the buffering effect of compression resistance and position limit, and double compression protection is designed at the bottleneck to effectively reduce the breakage rate.

4. The utility model maintains a sufficient buffer distance between the outer carton and the consignment, and the distance can be adjusted by the amount of inflation.

5. The PE+PA composite film used in the present invention is a new and effective buffer material.

6. After the utility model is inflated, a buffer space can be formed around the consignment, and the size can be adjusted, and it is suitable for all kinds of consignments with sudden changes in diameter and easy to break at the very thin part.

7. The single-piece PE+PA composite film before inflation of the utility model occupies less space.

8. The utility model does not need to fill other buffer materials after inflation, saves material resources, saves material costs, does not cause excessive packaging, and promotes green packaging;

9. The utility model has the advantages of simple structure, convenient use and simple operation.

Detailed ways

In order for those skilled in the art to better understand the technical solutions of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. In these drawings, the same reference numerals are attached to the same or equivalent components. The following are only the best embodiments of the present invention, and the present invention is not limited to the following contents.

As shown in FIG. 1 , the present invention provides an inflatable protective bag, which includes an outer buffer layer 1 , an inner buffer layer 2 is sleeved inside the outer buffer layer 1 , and the outer buffer layer 1 and the inner buffer layer 2 share the outer edge sealing, so The periphery of the outer buffer layer 1 is sealed, and the inner buffer layer 2 is ventilated with the outer buffer layer 1 .

The outer buffer layer 1 and the inner buffer layer 2 share the air inlet 3 .

The diameter of the inner buffer layer 2 has a taper.

The inner buffer layer 2 is wide on the side of the inflation port 3 and narrow on the side where the bottle neck is fixed.

The sealing edges of the outer buffer layer port 1, the inner buffer layer port 2 and the inflation port 3 share the same edge.

The inflation port 3 includes, but is not limited to, a two-port one-way air valve.

The inflatable protective bag adopts PA+PE composite film.

The production process of the present utility model comprises the following steps:

Step 1: As shown in Figure 2, cut a piece of PA+PE composite film according to the positioning size of the bottleneck and then fold it in half, heat-sealing both sides to form a bag structure, and make an internal buffer layer: one side of the inflatable opening is wide, and one side of the bottle neck is fixed. The side is narrow; and 2 single-port one-way air valves are fixed at the seal;

Step 2: As shown in Figure 3, after folding two PA+PE composite films in half, and fitting them together according to the combination of sets, heat-sealing the 4 layers on both sides respectively to form a bag that can hold gas in the middle;

Step 3: As shown in Figure 4, the two are combined in a set form, and the sealing parts are aligned. When heat sealing, add the other side of the two-port one-way air valve to synchronously heat seal, so that the air valve is in the form of two ports consisting of three pieces. , corresponding to the inflation of the two airbags respectively.

[Example 1]

As a preferred embodiment, this embodiment provides an inflatable protective bag, which is used as a protective cover for a red wine bottle.

When in use, inflate the outer buffer layer port 1 and the inner buffer layer port 2 through the inflation port 3, the taper of the inner buffer layer port 2 protects the bottle neck of the red wine, cover the bottle neck, and the outer buffer layer port 1 covers the entire bottle body. The upper part of the bottle increases the gap between the bottle and the bottle, so as to protect the fragile neck of the detail and protect the bottle body from impact.

The utility model utilizes aeration between the membrane and the inner membrane to increase the buffer volume, thereby achieving the buffering effects of compression resistance and position limit, and double compression protection is designed at the bottleneck to effectively reduce the breakage rate.
