Abstract

The utility model discloses a novel air packing bag, belonging to the air packing bag technical field, and comprising a bag connected with a cover body, wherein the end of the cover body is fixed inside the bag. The novel air packing bag of the utility model has the anti-counterfeit function and a simple structure.

Description

The new gas packaging bag

Technical field

The utility model discloses a kind of new gas packaging bag, belong to the technical field of gas packing bag.

Background technology

Traditional packaging bag is that several protruding air bag bubbles are set on plastic film chip, and the absorbing buffer action by the air bag bubble prevents that breaking or damaging phenomenon from appearring in transit in article.But in actual applications,, just can't reach the purpose that absorbing cushions, cause breaking or damaging of article easily for bigger vibration or impact load because the absorbing buffer action of air bag bubble is limited in one's ability.In the face of this situation, gas packing bag a kind of packaging bag of absorbing buffer action better effects if appearred, i.e. on the market.

As shown in Figure 1, existing gas packing bag comprise by several air chambers 8 ' form and have lid 1 ' bag 7 ', lid 1 ' end 2 ' be installed in sack limit 4 ' the top, sack limit 4 ' end, corresponding each air chamber 8 ' on be equipped with air valve 6 '.When gas packing bag is finished charge operation, each air chamber 8 ' interior aerification and expansion molding.The space that gas packing bag surrounded of expansion molding forms a spatial accommodation, can accommodate and desire to accommodate thing.Each air chamber 8 ' inlet channel 5 ',, therefore can cooperate sack 3 ' will desire to accommodate in the spatial accommodation that thing surrounds by this sack 3 ' insert gas packing bag so still be filminess because unaerated is expanded.Accommodate thing be subjected to air chamber 8 ' protection can avoid in transit because of vibration or impact occurring breaking or damaging phenomenon.

Though the absorbing buffering effect of this gas packing bag is fine, but has shortcoming, promptly do not possess the function of anti-personation, be easy to from sack 3 ' be removed because accommodate thing.

The utility model content

In order to overcome the shortcoming that exists in the above-mentioned prior art, the utility model provides a kind of possess anti-personation function and new gas packaging bag simple in structure.

To achieve these goals, the technical scheme that the utility model adopted is: a kind of new gas packaging bag, comprise the bag that is connected with lid, and the end of described lid is installed in bag inside.After the inflation, bag, lid expand, and after lid is positioned at the demi-inflation of bag in-to-in, the madial wall of bag is held out against, thereby with the sack sealing of bag.By this sealing mode,, after then bag or lid must being cut, could will accommodate the thing taking-up if will accommodate thing and take out with being received into the bag in-to-in.In case bag or lid are cut, this gas packing bag just can't reuse, and has therefore just possessed anti-personation function.

As the further setting of such scheme, the sack limit of described bag is higher than the lid top.After the inflation, the pocket portion of sack avris can be folded to lid along the heat-sealing line, lid be covered, and the sack end is used as the bottom, further improve the absorbing buffer action of this gas packing bag.

Described sack limit end offers the air valve that is connected with each air chamber of bag.Air valve is arranged on sack limit end, makes the structure of whole gas packing bag more compact, and inflation is also convenient.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is the structural representation of existing gas packing bag when unaerated;

Fig. 2 is the structural representation of the utility model new gas packaging bag when unaerated;

Fig. 3 is the structural representation after Fig. 2 inflation.

The specific embodiment

Shown in Fig. 2,3, the packaging bag of the utility model new gas comprises the bag 7 that is connected with lid 1, and the end 2 of lid 1 is installed in bag 7 inside.The sack limit 4 of bag 7 is higher than lid 1 top 3.Sack limit 4 ends offer the air valve 6 that is connected with bag 7 each air chamber 8.

During use, will accommodate thing earlier and put into bag 7 inside, and cover, put on the air by 6 pairs of each air chambers 8 of air valve again by lid 1.After inflation finished, bag 7, lid 1 expanded, and after lid 1 is positioned at bag 7 in-to-in demi-inflations, the madial wall of bag 7 is held out against, thereby with the sack sealing of bag 7.In addition, after the inflation, bag 7 parts of sack limit 4 sides are folded to lid 1 along heat-sealing line 5, lid 1 are covered, and this sack end is used as the bottom, can further improve the absorbing buffer action of this gas packing bag.
