Description

The utility model relates to a container device, in particular to a container bag body specially used for containing gas or liquid and having a gas nozzle that can be automatically closed.

At present, there are the following three types of bags used to hold gas or liquid. The first type is a soft bag with a filling neck. The mouth of the bag is closed by a knot to prevent leakage of the contents. This kind of containing bag is more inconvenient in use, and it is very easy to leak a part in the process of tying and knotting.

The second category is the packaging bag that is hot-melt-sealed after filling, such as the packaging of various fruit juices, milk and some liquid condiments, but this kind of packaging bag not only requires hot-melt sealing equipment, And, must adopt special fusible plastic film to make bag body, be subjected to bigger restriction in use.

The third type is an inflatable toy, which is provided with an air tube on the side of the body to provide inflation. After the inflation is completed, a plug or screw is installed at the opening of the air tube. For example, a hollow shape inflatable toy made of plastic film Most of them adopt this structure, and its disadvantage is that it cannot or is inconvenient to be used for small packages of small items, and its airtightness is poor, and it is not suitable for liquids.

Another common shortcoming of the above several types of containing bags is that they cannot bear pressure basically, that is, the pressure of the inner filling medium is very small, because the sealing parts of the above structures are more likely to leak under the action of internal pressure. Especially can not rely on bag body self and inner pressure self-sealing.

The purpose of this utility model is to overcome the above-mentioned shortcomings and deficiencies in the prior art, and to provide a simple structure, convenient and practical, which can automatically close the hole after filling, and has a good sealing effect and a self-locking air nozzle. The container bag body.

The purpose of this utility model is achieved by the following technical solutions:

There is a V-shaped air nozzle connected to the air-filling hole on the outside of the packaging bag that is folded in half with an air-filling hole. , inserted into the V-shaped air nozzle through the intubation tube, and the internal pressure of the bag after inflation will enter the air bag. The pores are closed to prevent the filling from leaking back.

Visible from above: the remarkable effect of the present utility model is:

1st: After being filled with gas and liquid, the gas-filled hole will be closed automatically under the action of its internal pressure, thus not only eliminating the need for binding, knotting, hot-melt blockage and other procedures and corresponding sealing equipment, but also reducing the cost accordingly. The cost is reduced, especially the good sealing effect of self-closing.

No. 2: Simple structure, convenient and practical.

No. 3: It has the advantages of one-time continuous completion of inflation and sealing, which can not only reduce the flow loss of filling materials when they are tied, but also improve production efficiency.

No. 4: Because it is self-sealing by internal pressure, as long as the bag is made of soft airtight material, it can be applied and has good adaptability.

Concrete structure of the present utility model is realized by following embodiment and accompanying drawing thereof:

Fig. 1 is the plane structural drawing of the present utility model.

Fig. 2 is a longitudinal sectional view of the utility model when it is inflated.

Fig. 3 is an effect diagram of the utility model when it is inflated.

Fig. 4 is an effect diagram of the utility model after being inflated.

Below in conjunction with accompanying drawing 1-4, concrete structure of the present utility model is described in detail:

The utility model has a soft hollow bag body 1 that is folded in a pair and sealed around the periphery. The sheet 11 has an inflation channel 111 in the longitudinal direction. The inflation channel 111 communicates with the air nozzle 12 on the outside of the bag body 1 . See Figures 1 to 4

The utility model is characterized in that

The soft air nozzle 12 is V-shaped, and the periphery of the air nozzle 12 is a double-layer closed structure. The air port 1211 of the air bag 121 communicates with the inside of the bag body 1. It is a hollow bag composed of symmetrical plastic or rubber films that are folded and sealed in half. The closing direction of the V-shaped air nozzle 12 of the body 1 and the air-filling channel 111 communicated with the V-shaped air nozzle is parallel to or 90 degrees to the folded surface of the hollow bag body 1 . See Figures 1 to 4

The usage method of the utility model is shown in Fig. 3 and Fig. 4

When it is desired to fill the inside of the bag body 1 with gas or liquid, a cannula 2 can be used to insert the V-shaped gas nozzle 12 into the bag body 1 through the inflation hole 111, so that the inflation hole 111 is stretched, so that the Intubate the tube 2 to fill the gas or liquid into the bag body 1 to achieve the purpose of filling gas or liquid; The pressure of the gas or liquid in the body 1 will naturally press the inflatable hole 111 from both sides of the inflatable hole 111, so that the wall surface will return to the closed state of bonding; The air port 1211 connected to the inside of the bag is filled into the air bag 121 on both sides, so as to automatically compress the inner wall surface of the inflatable hole 111 and the V-shaped air nozzle 12 again. As a result, it will form a wrinkled shape, thus forming multiple locking effects to achieve the purpose of ensuring that the gas and liquid will never leak back; on the contrary, if you want to extract the gas and liquid in the bag body 1 from the bag body 1, you can use it again By inserting an intubation tube 2 into the inflation hole 111 from the gas nozzle 12, the inflation hole tube 111 can be stretched again, so that the gas and liquid escape from the bag body 1.

In addition, because the shape of the air nozzle 12 is a V-shape, it can be used for intubation tubes 2 of various sizes. The material of the air nozzle 12 can be the same as or different from the rubber or plastic material of the bag body 1, and can also be matched with various Various materials and bag bodies 1 of various different regular shapes are used.
