detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described further, to help understanding content of the present utility model.

As shown in Figure 1, Inflatable bag packaging structure is made up of the cylindrical shell 5,8 of two both ends opens that are made up of air bag, on the barrel of cylindrical shell 5, be arranged with plenum chamber 3 and the filling channel of inflating and inlet non return check valve, on the barrel of cylindrical shell 8, be arranged with plenum chamber 4 and the filling channel of inflating and inlet non return check valve.When packaging, the frangible commodity that are made up of tank body 2 and cover 1 are passed through to the opening of less cylindrical shell 5 one end, completely charged air bag air chamber cylindrical shell 5 is enclosed within to jar outside, and then completely charged larger cylindrical shell 8 is enclosed within outside commodity and cylindrical shell 5 by the direction vertical with less cylindrical shell 5, such two cylindrical shells 5, the opening at 8 two ends is sealed respectively mutually, the space that two cylindrical shell middle parts surround is the space of placing commodity, plenum chamber all wraps all commodity circumferencial directions, any direction can reach apparatus with shock absorbing, realize the protection of any direction, simultaneously on tank body, lower two sides are the two-layer plenum chamber intersecting in length and breadth, so in upper and lower both direction protection better effects if, this is that the direction of vibration upwards propagated by commodity bottoms is consistent with the vibrations in handling process, therefore protect better effects if.

Because cylindrical shell 8 is to be enclosed within cylindrical shell 5 outsides, therefore cylindrical shell 8 need to be larger than cylindrical shell 5, and too large cylinder 8 easily gets loose from cylindrical shell 5 and commodity, too little not facility for nesting and taking off.Best is that the bulk that two cylindrical shells wherein surround compared with large cylinder 8 after inflation is greater than the bulk surrounding of less cylindrical shell 5, and is less than this less cylindrical shell outside dimension.Because pressurized after cylindrical shell 8 and cylindrical shell 5 inflations can both be out of shape, therefore both can realize cylindrical shell 8 had been enclosed within outside cylindrical shell 5 without taking too great strength, again the difficult drop-off due to the mutual pressure of both air chambers generations.

There is an opening 6 at described less cylindrical shell middle part, can well locate the special construction position of commodity, for example in Fig. 1 cover 1 carry button position, play good fixation.

On the barrel wall of described cylindrical shell 5,8, the arrangement mode of plenum chamber 3,4 is that each plenum chamber is all around barrel wall one week.

Shown in Fig. 3, the plenum chamber on barrel wall is distributed with four heat seal point 32 on its length direction, is the shape of rectangle so that it makes cylindrical shell cross section from heat seal point bending as shown in Figure 1 after inflation.While making two barrel jackets together, form cube body structure, its bottom surface is stable plane like this, is convenient to particularly stable the piling up of stable placement of commodity and packaging.

Form the air bag of cylindrical shell as shown in Figures 2 and 3, be that two wide plastic sheetings 11,12 are placed in top layer, be placed in interlayer with two narrow plastic sheetings 21,22 of polarity, through the structure with multiple bar shaped plenum chambers 13 forming in hot thread 33,34,42,43,44 place's heat-sealing bonding, wherein plenum chamber 13 is to form locular wall by wide plastic sheeting 11,12.The attached inlet non return check valve of self-priming that each bar shaped plenum chamber 13 forms at intake and exhaust end by two narrow plastic sheetings 21,22 communicates with flute shaped inflatable overall channel 7.Flute shaped inflatable overall channel 7 is also to form between two wide plastic sheetings 11,12, because this overall channel is vertical with each bar shaped plenum chamber direction and corresponding each bar shaped plenum chamber direction all has the passage that can ventilate, the flute hole of similar flute is the same, is therefore called flute shaped inflatable overall channel.This like this inflatable plastic folder film as shown in Figure 2, by being heat sealing at the flute shaped inflatable overall channel 7 of two wide plastic sheeting 11,12 upper limbs, inflate to flute shaped inflatable overall channel 7, air pressure makes to adsorb separately the narrow plastic sheeting 21,22 fitting together in inlet non return check valve and separates to form path, air can enter each bar shaped plenum chamber 13, and bar shaped plenum chamber 13 expands and forms gas column.Stop inflation between two narrow plastic sheetings 21,22 in self-suction and plenum chamber under gaseous tension effect two plastic sheetings 21,22 fit together again, free air diffuser is closed air can not be leaked.Utilize the gas column apparatus with shock absorbing forming after inflation, reach the effect of extraordinary damping and protection commodity.

Want shape cylindrical shell, also need the folder of inflatable plastic shown in Fig. 3 film through folding and secondary heat-sealing.By direction doubling shown in the folder of the inflatable plastic with bar shaped plenum chamber and the inlet non return check valve film edge broken line 36 vertical with bar shaped plenum chamber 13 in Fig. 3, after doubling, carry out secondary heat-sealing along near edge sealing hot thread 41 positions shown in the free edge edge of both sides in figure, plastic film after doubling is bonded as one along hot thread 41, forms the tube structure that all the other bandings of both ends open close.Due in the time inflating, when the bar shaped plenum chamber retaining expands, its free edge can form and be similar to " frame " shape shape with respect to pocket portion (part of package goods) to spatial expansion as shown in Figure 1, by two or more polyhedral structure packaging bags, be and be staggered in locus, just form the well word shaped as frame air bag with multiaspect multi-buffer fail-safe structure, therefore by the packaging bag of this packaging bag called after well word shaped as frame.Well word frame-shaped construction makes it more stable when direction is placed as shown in Figure 1.Hot thread 41 middle parts disconnect the opening 6 that can form in Fig. 1.

In order to improve the attached inlet non return check valve sealing effectiveness of self-priming, two narrow plastic sheetings that form inlet non return check valve adopt from absorption polarity plastic sheeting, as CN103275630A, are to be compounded with self-adhesive layer in a side of PE base material, form one side from adsorption film material.

For improving sealing effectiveness, as shown in Figure 2, in two described narrow plastic sheetings 21,22, the thickness that forms a slice Polar Crystal Slab material 22 of inside and outside space obstacle layer is the 100%-135% of another sheet Polar Crystal Slab material 21 thickness, and the barrier layer thickening is more conducive to provide sealing effectiveness.

For ease of when inflation well word shaped as frame air bag in ad-hoc location bending, to form the bottom of a stable damping shown in Fig. 1, also be convenient to keep shape shown in Fig. 1 to be beneficial to pack into easily commodity simultaneously, as shown in Figure 3, be that broken line 36 both sides are positioned at bar shaped plenum chamber place and are provided with horizontal hot thread 32 being positioned at position, folding part, two wide plastic sheetings that form plenum chamber are bonded together at middle part, so that it diminishes in these broken line 36 position bend resistance abilities, be conducive to nature in the time of inflation and bend effect shown in this generation Fig. 1.Hot thread 32 length are less than bar shaped plenum chamber width, making hot thread 32 two ends and bar shaped plenum chamber edge is between hot thread 33, to retain certain venting channels, make air can inflate and form by this position equilibrium air pressure to whole bar shaped plenum chamber, not only make packaging bag two load bearing face air pressures identical, and the more important thing is that the circulation of air runner that these hot thread 32 places diminish has decompression throttling action, in the time that a side is subject to suddenly impacting, gas can be pressed onto rapidly opposite side once, avoid gas column to be crushed rapidly and directly impact inner commodity, simultaneously not only there is portion gas can enter opposite side but also avoid this side gas column internal pressure that is hit too high and make this side plenum chamber explosion.

Shown in Fig. 1; after 36 doublings of broken line in Fig. 1; bottommost edge in Fig. 1 and the heat-sealing of top edge are connected together; for example aligning hot thread 41 with hot thread 35 seals; forming single bar shaped plenum chamber is the form around bag configuration; it is more limited that this single structure is compared well word shaped as frame protectiveness, can only protect commodity several, do not have well word shaped as frame packaging bag protection comprehensively.
