Abstract
The utility model relates to the field of a protective device of goods transportation, in particular to a multi-bubble type inflatable packaging bag which comprises at least two air bubbles, one air bubble is provided with an air inflation opening, and an air valve is arranged inside each air bubble. Each air valve is fixed with each air bubble wall in a thermofussion welding mode to form a gas channel, one gas channel is communicated with another gas channel through a gap arranged between air bubbles, each air valve comprises an outer membrane and an inner membrane, and openings of the outer membrane and the inner membrane are arranged in a staggered mode. The multi-bubble type inflatable packaging bag has the advantages that by means of arrangement of one-way air valves which are arranged inside a plurality of continuous air bubbles, the multi-bubble type inflatable packaging bag is sealed in a self-sealing mode through air pressure and free form being sealed in a welded mode, and thus a packaging bag is simple in structure, convenient to use and high in inflation speed. Moreover, fracture of one air bubble does not affect the others, so that goods are well protected from being damaged. Moreover, the utilization of the inflation channel enables the inflation speed of an inflatable packaging bag to be higher, and the packaging efficiency of the goods is improved.
Description
Technical field
The utility model relates to the fender guard field of article transportation, refers in particular to a kind of many bubbles formula gas flushing pouch.
Background technology
The development of logistics at present rapidly, and is strict more to the packing requirements of article, can not satisfy the safe and sanitary demand through using measure protection article such as newspaper, cloth waste, and make article impaired easily.In the market more use have minute bubble plastic device be used for protecting article, but these had air the bubble membrane volume big, it is inconvenient to store transportation.Gas filed again packaging bag in the time of can using is also arranged, and the tank dome of packaging bag generally is into strip, in case but in the packaging bag aperture is arranged, can cause whole piece tank dome venting and the effect such as shockproof of influence packing.
Summary of the invention
For overcoming the above problems, the utility model provides a kind of many bubbles formula gas flushing pouch that can tank dome is divided into plurality of sections and be independent of each other.
A kind of many bubbles formula gas flushing pouch; Comprise at least 2 air filled cavitys; An air filled cavity is provided with inflation inlet, is provided with air valve in each air filled cavity, and gas flow is fixed and formed in air valve and the thermofussion welding of air filled cavity wall; Communicate through the space that is located between the air filled cavity between each gas flow, said air valve comprises adventitia and the inner membrance that opening staggers.
Further, be printed with anti-melting welding coating between the said air filled cavity.
Further, interconnect between the adventitia of said air valve and the inner membrance, and leave the gas channel that adventitia opening and inner membrance opening are communicated.
Further, have autohension between the adventitia of said air valve and the inner membrance.
Further, air filled cavity also is unified into the air filled cavity string, and first air filled cavity is provided with inflation inlet.
Further, this packaging bag comprises at least 2 air filled cavity strings, interconnects between the air filled cavity string, also comprises filling channel, and said filling channel is provided with inflation inlet, and filling channel communicates with the inflation inlet of each air filled cavity string.
The beneficial effect of the utility model is: the Non-return air valve through in the air filled cavity that plurality of continuous is set seals, and it carries out self sealss through air pressure and need not welded seal, thereby makes the simple in structure of this packaging bag, and easy to use, aeration speed is fast.And breaking of an air filled cavity do not influence other air filled cavity, and the better protection article make it not impaired.And the use filling channel, make the aeration speed of gas flushing pouch faster, improve article packing efficient.

The specific embodiment
Embodiment 1
In conjunction with accompanying drawing 1-2; A kind of many bubbles formula gas flushing pouch; Comprise that 1, one air filled cavity 1 of 2 air filled cavitys is provided with inflation inlet 2, is provided with air valve in each air filled cavity 1; Each air valve communicates through the gas channel 6 that is located between the air filled cavity 1 with space between the air filled cavity wall 5, and the opening 7 of the adventitia 3 of said air valve and the opening 8 of inner membrance 4 stagger each other.Interconnect through point of connection 9 between the adventitia 3 of said air valve and the inner membrance 4, and leave the gas channel that adventitia opening 7 and inner membrance opening 8 are communicated.
Further, have autohension between the adventitia 3 of said air valve and the inner membrance 4.Adventitia 3 is asymmetric multi-layer co-extruded compound PE film with inner membrance 4; (its function class is similar to the protective film that common electrical equipment surface is pasted to structure like: A layer PE, the bonding PE of B layer, C layer autohension PE; A toughness; Can glue back again after the strip off) key distinction is in the control of viscosity, this is to adjust on the material when producing, selected for use of film.The viscous layer of adventitia 3 and inner membrance 4 will be put together to guarantee its air-tightness in the air valve.。
Embodiment 2
As shown in Figure 3, a kind of many bubbles formula gas flushing pouch, some air filled cavitys 1 also are unified into the air filled cavity string, and first air filled cavity 1 is provided with inflation inlet 2.This packaging bag comprises at least 2 air filled cavity strings, interconnects between the air filled cavity string, also comprises filling channel 10, and said filling channel 10 is provided with inflation inlet 11, and filling channel 10 communicates with the inflation inlet 2 of each air filled cavity string.
Be two-layer from sticking together in the unaerated between said air valve adventitia 3 and the inner membrance 4, middle meeting forms certain gap when air admission, so that air admission.
As shown in Figure 4, when inflation, air gets into each through filling channel 10 and connects the inflation inlet 2 of air filled cavity, and passes the opening 7 entering air valve spaces of air valve adventitia 3, and air is got in the air filled cavitys 1 by the opening 8 of inner membrance 4 again.After inflated; Because the air pressure in the air filled cavity 1 is higher than external pressure; At this moment, the air in the air filled cavity 1 is closed the air valve of double membrane structure, and air can prolong space between air filled cavity wall 5 and the adventitia 3 to next bubble aeration through gas channel 6 after an air filled cavity is full of.So just can be to continuous bubble aeration, realization seals and need not to weld, and prevents escape of gas.
The utility model is not limited to above-mentioned specific embodiment, and under the situation that does not break away from the spirit and scope of the present invention, all variations and modification are all within scope of the present invention.
