Description

A kind of Novel air password protection thermometer bulb

Technical field

This utility model is related to a kind of insulation bag, refers in particular to a kind of Novel air password protection thermometer bulb.

Background technology

Insulation bag, for keeping article or food in constant temperature or the container of certain limit temperature, with thermal protection or The function of cold insulation, to ensure the fresh and hot-cool demand of article or food, be now widely used in go on a tour carrying food and beverage, Transport and outdoor location in road.

Early stage insulation bag is usually manufacture process for sewing, makes the inner and outer boundary of inclusion just have gas mutual by the vacuum of sewing Mutually infiltration is so as to reduce the temperature retention time in wrapping, on material using woven dacron add one layer of 3-6mm PE Foam interlayer and one layer thin It is thin inside, effect of heat insulation is also unsatisfactory；Typically using Typical zipper closure or folded closed in structure, Typical zipper Slot and folding wiredrawn edge can not be effectively blocked the circulation of Bao Nei and outside air, due to said structure design, processing technology And the defect of material function, it is difficult to meet people's requirement in use.

Later stage insulation is surrounded by and is improved, but square, circular or oval-shaped base is only limitted in structure plus one circle inclusion adds again One with the lid of bottom same shape, but this kind of mode limits the various sizes of demand of product, and change size needs a set of New weld mold, causes production cost to improve the defect with inefficiency；Opening mode is using the drawing around inclusion and lid Chain opening mode, but opening range make insulation wrap portion open cross-section it is excessive, so as to allow thermal insulation barn open lid when Under being fully exposed to extraneous too high or too low temperature environment, so as to reduce the insulation persistent period；Heat preserving mode is adopted and passed through The method partition heat preservation function layer of welding internal layer and outer shell fabric attempts to realize heat insulation function, but is because that what is be incubated it is critical only that maximum The cut-off of the degree air contact larger with the extraneous temperature difference for filling the thermal insulation barn of food, and cut-off is not lain in internal layer and outer Sandwiched area between shell fabric, the heat insulation function that can not effectively improve by this way improves difficulty, drop to production on the contrary Poor efficiency, also improves production cost.
