Description
Technical field
The present invention relates to the outer wrapper for sealing article up for safekeeping, more particularly to a kind of water proof type sealing shroud.
Background technology
At present, most of electronic product does not typically possess the function of having waterproof against pressure, cause people swimming, diving or
Outgoing drifts of spending holidays, bath in hot spring etc. water activity when entrained mobile phone, wrist-watch, the use of digital camera bring it is very big not
Just.Entrained electronic product, which has accidentally got wet, to be just broken；Some are easily by the temperature of environment, humidity, illumination and electricity
Magnetic etc. influences larger apparatus, article in storage and transport process, and especially in adverse circumstances, the property of article can occur in various degree
Change, have in addition can go bad or fail therefore, certain safeguard procedures are taken in storage or transport, to ensure goods and materials
Safe storage and transport.Means of defence is more, and wherein conventional method is that coating butter is connect with completely cutting off goods and materials with air on apparatus
Touch, with moistureproof antirust；Other also useful vapor phase inhibitor technology prevents the apparatus from making moist corrosion, though these means of defences can be in short-term
In play certain protection effect, but can not ensure in prolonged storage from environmental attack, and this protection side
There is many defects such as operation inconvenience in high-volume accumulating in method；In addition, also there is part thereof to use plastic-aluminum vacuum envelope bag
Dress, the packaging can be allowed to thoroughly completely cut off with external environment, also can effectively prevent influence of the illumination to goods and materials.
The defect of prior art：Electronic product is fitted into the waterproof bag with valve port and fastener, passes through multiple winding
Sack is buckled on bag, and the air in bag is discharged by valve port, such waterproof bag, not tight enough due to sealing, easily
Infiltration, waterproof function against pressure；Seal sleeve structure is unreasonable, and sealing is poor, cause goods and materials in long-term storage and transport process still can corrosion,
Damage, go bad etc.；Secondly, there is many drawbacks in the material for preparing big envelope, and such as resistance to property exposed, tear resistance are poor, especially in the wild
In low temperature environment, envelope material pliability is poor, easily damaged after soft folding, and it is rotten that this not only causes military hardware or goods and materials to lose envelope,
Storing and transporting security is poor, and in the case of electromagnetic interference, part equips easily failure and loses use value；Overall hermetic seal
Although deposit equipment store apparatus and during goods and materials with it is certain moistureproof, sun-proof, dust-proof and anti-oxidation the effects such as, should
Equipment air-tightness is poor, and parts are more, and structure is more complicated, tedious process when using and dismounting every time.
