Description

The air bag that has exhausr port

Technical field

The utility model relates to a kind of packaging bag, particularly a kind of air bag that has exhausr port.

Background technology

The space of traditional packing chest is filled and is generally made by foam; pack in the case according to the shape of article; especially in the time of in breakables are packed case into; this foam carpet has been full of the remaining space of packing chest; the volume of the article that the volume ratio of such space weighting material is protected is big, and the environmental protection that is treated to after the foam carpet usefulness is also made troubles.

At present, the mode that is used for the buffering package article is dashed forward on many plastic sheets and is established a plurality of protruding ballonets, and this plastic film is coated on the article periphery and reaches the shock-absorbing buffer action, but the damping capaicty of ballonet is limited, just can't reach the effect that cushions shock-absorbing for bigger vibrations or impact load.

Continuous research and development through these those skilled in the art, some inflatable packaging bags have appearred on the market, this type of inflatable packaging bag is made of two interconnective outer membranes of periphery, two outer membranes be divided into upper diaphragm and down on the diaphragm outer membrane and down outer membrane interconnect its inner annular seal space that forms of back, be provided with an interior diaphragm in the annular seal space, the inwall of this interior diaphragm and last outer membrane is fitted, form a unidirectional air-stopping valve, this type of packing air bag need be taken out the object that coats after using then needs have sharp weapon to break annular seal space, and the air emptying in the annular seal space could be taken out coating; Gas flushing pouch after breaking has just lost effect, can only be used as waste disposal, and gas flushing pouch can not get the use of repetition, not only wastes resource, and has improved productive costs.

Summary of the invention

At the deficiency that prior art exists, the utility model provides a kind of air bag that has exhausr port of reusable, saving in material.

For achieving the above object, the utility model provides following technical scheme: a kind of air bag with exhausr port, include two interconnective outer membranes of periphery, two outer membranes are divided into outer membrane and reach outer membrane down, last outer membrane reaches down, and outer membrane interconnects its inner annular seal space that forms of back, be provided with an interior diaphragm in the annular seal space, described annular seal space is divided into inflatable chamber and discharge chamber, described discharge chamber is provided with exhausr port, the folding serpentine that is of described interior diaphragm, two symmetrical limits are attached at respectively between the connection side of outer membrane and following outer membrane periphery on the interior diaphragm, one end of interior diaphragm places in the inflatable chamber, and fit with last outer membrane, and be provided with inflation inlet between the periphery of interior diaphragm and last outer membrane, the other end of interior diaphragm places in the discharge chamber, and is sticked with following outer membrane and puts, and interior diaphragm is provided with the interface channel of inflatable chamber and discharge chamber between inflatable chamber and discharge chamber.

Annular seal space is divided into inflatable chamber and discharge chamber in this, described discharge chamber is provided with exhausr port, the folding serpentine that is of described interior diaphragm, two symmetrical limits are attached at respectively between the connection side of outer membrane and following outer membrane periphery on the interior diaphragm, one end of interior diaphragm places in the inflatable chamber, and fit with last outer membrane, and be provided with inflation inlet between the periphery of interior diaphragm and last outer membrane, the other end of interior diaphragm places in the discharge chamber, and be sticked with following outer membrane and put, interior diaphragm is provided with the interface channel of inflatable chamber and discharge chamber between inflatable chamber and discharge chamber.Be arranged on like this and use the back air-out to need not packaging bag is broken, air can be discharged from the exhausr port of discharge chamber, and it can be reused, and economizes on resources and material.

The utility model further is set to: separate by the heat-sealing line between described inflatable chamber and the discharge chamber, the interface channel of described inflatable chamber and discharge chamber is located between interior diaphragm and the following outer membrane, and be provided with heat-resisting joint herein, described inflatable chamber is provided with some and is the heat-sealing line of vertical configuration with discharge chamber, constitute several inflation post chambeies, the described post chamber of respectively inflating is communicated with discharge chamber by interface channel respectively, and the exhausr port on the described discharge chamber includes the hole and the plunger that are communicated with discharge chamber and constitutes.

Separate by the heat-sealing line between inflatable chamber and the discharge chamber in this, the interface channel of described inflatable chamber and discharge chamber is located between interior diaphragm and the following outer membrane, and be provided with heat-resisting joint herein, setting can not only be divided into annular seal space two chambeies like this, and can make between two chambeies and obtain good conducting; Described inflatable chamber is provided with some and is the heat-sealing line of vertical configuration with discharge chamber, constitute several inflation post chambeies, the described post chamber of respectively inflating is communicated with discharge chamber by interface channel respectively, and setting can enlarge the range of use of packaging bag like this, can decide according to design as for the number in inflation post chamber; Exhausr port on the discharge chamber includes the hole and the plunger that are communicated with discharge chamber and constitutes, and setting can make its quick exhaust like this, and easy to process.

The utility model further is set to: the binding face of outer membrane was provided with leakage barriers under described interior diaphragm and last outer membrane reached.Described leakage barriers is for placing interior diaphragm and last outer membrane and the heat seal point on the binding face of outer membrane down respectively, and described heat seal point is rounded, is applied with on the described binding face of going up outer membrane and interior diaphragm to be the triangular shape that is oppositely arranged and to seal line.

Binding face of outer membrane was provided with leakage barriers under interior diaphragm and last outer membrane reached in this, leakage barriers is the heat seal point on the binding face that places interior diaphragm and last outer membrane and following outer membrane respectively, described heat seal point is rounded, is applied with on the binding face of described upward outer membrane and interior diaphragm to be the triangular shape heat-sealing line that is oppositely arranged.Be provided with simple in structure like this and do not need to add in addition material, saved productive costs, after when air enters inflation post chamber along interior diaphragm and last outer membrane in, gap between many more interior diaphragms of air and the last outer membrane is more little, through more guaranteeing its sealed against leakage after charging into air after being provided with of leakage barriers, applying leakage barriers on following outer membrane and the interior diaphragm also is as a same reason, and applying of leakage barriers also can guarantee interior diaphragm and last outer membrane and the applying between the outer membrane down, can prevent interior diaphragm from last outer membrane and down outer membrane come off.

Below in conjunction with accompanying drawing the utility model is further described:

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is the A-A part sectional view of Fig. 1;
