Background technique
With the development of global economy, commodity transaction more and more becomes a part important in life, and along with naughty
It is precious, when the rise when large quantities of current internet business platforms such as, Jingdone district, shopping online has become very universal phenomenon, also makes
With regard to flourishing for transportation logistics industry.A large amount of online commodity need to transport in buyer's hand after packing, therefore in transport
The shock resistance of the packaging material of commodity proposes very high requirement, and showing market to apply at most is air type sealing bags, at
This is cheap, is thin layer plastic sheet before inflation, heaves after inflation and play shockproof effect, air anti-vibration was packed from 2000
Bag product is just studied and releases new departure, but basic principle, still using two layers of outer membrane as inflatable bag body, two layers of inner membrance constitute bag
Air valve film device on body, air valve film working principle are upon inflation, since external pressure is higher than air pressure in bag body, so two layers
Inner membrance meeting " being blown open ", allows gas can smoothly enter into bag body;After inflation, since air pressure is higher than external pressure in bag body,
And bag body can be expanded because of inflation, so that two layers of outer membrane near air inlet is no longer parallel, but be stretched around, therefore two layers
Inner membrance has pressed to bag body side by air pressure inside, is bent and fits together jointly with this layer of outer membrane, realizes that closing is located in two layers
Air inlet between film achievees the effect that air non-return.
In order to preferably " blow " two layers of air valve film open, application number 200610067311.5 " there is seal to hold one's breath automatically
And the air cushion body of device and preparation method thereof of lock gas " a kind of mode for taking heat-sealing opening point of Patent design, tool
Body includes: continous way seal, interior to contain two panels outer membrane, two panels inner membrance, is applied in one inner membrance inner face top equidistant intervals
It is furnished with heat proof material and forms several resistance to thermal centers (1c), be applied with heat on two outer membranes, at the vertex lower section resistance to thermal center (1c)
Seal point (2c), heat seal point (2c) make adjacent outer membrane and inner membrance then;Therefore when inflating port inflation, outer membrane is in air flue part because swollen
It is swollen and its inner membrance being connected to can be pulled open, so that being all turned on along all air intakes of air flue in moment, accelerate inflation
Speed, efficiency are very high.
But above-mentioned patent, either " resistance to thermal center (1c) " are still " heat seal point (2c) ", require to carry out to positive (to mark)
Printing.Once operation printing over long distances is easy the accumulation of error making scrap of the product to the center for deviateing air outlet valve film, because
It is time-consuming and laborious constantly to mark (guaranteeing central point) in this production.
For this disadvantage, inventor has applied for a kind of " shockproof air column bag of no opening point " (Shen on June 29th, 2018
Number 201810697197.7) please, heat resistant oils ink-stick is directly a long straight line, rather than spaced before various " heat-resisting
Section " form, production technology simplify, without to mark step;And by the inflatable area of the left and right settings in perpendicular hot-sealing line,
After inflation alternative original " heat seal point (2c) ", and the bottleneck shape of outer contour energy self-assembling formation air inlet, not only make to inflate
Smooth convenience, and this structure is due to the presence without " resistance to thermal center " height allows inner membrance height from original 70mm
It is shortened above to 50mm hereinafter, save the cost can not be estimated.
But after actually using a period of time, inventor has found that above scheme also has place to be modified, such as due to heat resistant oils
Ink-stick between the entire bag body of lateral direction penetrating, therefore inflate before, it is necessary to preset and pass through the closed of the heat resistant oils ink-stick
Hot-sealing line, to prevent gas from leaking out from perforation place of heat resistant oils ink-stick;Secondly, between each inflatable area due to
It also can mutually collaborate when being mutually communicated, therefore inflating, both influence intake velocity, also influence the pulling force opened.
