Description
Technical field
The utility model relates to a kind of insulation bag.
Background technology
Insulation bag, belongs to the one of outdoor case and bag, is that it also may be used for refrigeration for containing various food and keeping the bag of food temperature and freshness, and as put into the cold items such as ice cube, cold drink, therefore thermal protection cold insulation is the most basic function of insulation bag.
In prior art, insulation bag generally has heat-insulation layer, heat-insulation layer wrapped up by inner layer cloth and outer layer cloth, outer layer cloth is also formed the half opening installed for slide fastener, form upper cover above half opening, half opening issues the moist closet that formation is surrounded by outside, heat-insulation layer and inner side successively, pulls slide fastener to open or close upper cover, get thing from moist closet very convenient, the warm material that current heat-insulation layer adopts generally has nonwoven fabrics, aluminium film expanded polyethylene foam, oxford and terylene etc.
One is had to the insulation bag of excellent heat-insulating property, on the basis adopting heat-insulation layer, the leak tightness of moist closet is also the key of insulation, existing insulation bag inner layer cloth and outer layer cloth are sewed up in the mode of opening part by sewing, inner layer cloth and outer layer cloth are also sewed up by some fritter clothes and are formed, and existing insulation bag also exists following defect:
One, the inner layer cloth that the mode sewed up by fare is combined and outer layer cloth, its sealing effectiveness is also bad, pin hole is left at suture, inner layer cloth and outer layer cloth can not seamless combination completely, inevitably reduce the leak tightness of insulation bag, extraneous air easily forms convection current by the gap between pin hole or ectonexine and inner air, and cause the change of insulation bag internal temperature, heat insulation effect is not good;
When two, depositing cold items (as ice cube), under having there is cross-ventilated situation, ice melting or air setting, the water in heat-insulated cavity is caused to flow out from skin along slit flow to heat-insulation layer, in addition inner cold air also may cause outer field suture (particularly zipper opening place) to occur the situation of condensation vapor, above-mentioned situation all causes heat-insulation layer to reduce service life, and the aging gap that easily causes of ectonexine suture expands further, reduces insulation bag useful life;
Three, inner side and the skin of existing insulation bag are generally directly sew up at opening part, inner layer cloth much larger than its cross-sectional plane bottom moist closet, cause inner side cloth to occur the problem of fold, and some needs the insulating article inconvenience of regular placement to place at the cross-sectional plane of the opening part on moist closet top.
In view of this, the present inventor's especial manufacture goes out a kind of insulation bag realizing complete sealing thermal insulation room, and this case produces thus.
