Shape structure, different according to specifically used purposes, hold-over plate is processed into a variety of volumes, but storage of the prior art again
Cold drawing is universal thicker, cause in-convenience in use.Coordinating transport cases in use, traditional hold-over plate can only be placed on and be transported
The surface of object and surrounding, cause cold quantity transmission in casing uneven, if needing the article product of transport in cold chain transportation process
It is kind more various, or laying for goods it is irregular when, disadvantages mentioned above then becomes apparent.In addition, traditional hold-over plate is only suitable for
Transit link in Cold Chain Logistics, it is impossible to applied to daily life, i.e., general consumer can not contact and use.In cold chain thing
The least significant end link of stream, consumer still successfully can not freely shift the article of Keep cool the state of needs, in item transfer
When need to also be packed by inconvenience refrigerating box, the cold insulated cabinet that use etc..This just produces a kind of cold storing bag.
At present, using can be disposable ice bag, mainly inhaled in layer of non-woven fabric and one layer of plastic foil central filler
Water cold storage agent, the structure in four bandings jail；Its is simple in construction, but non-woven fabrics face easy to leak, water suction agent for storage of coldness with by chilled goods
Mutually pollution, isolation effect is poor.
The content of the invention
The purpose of this utility model is to solve shortcoming present in prior art there is provided a kind of cold storing bag, can be with it
The body surface of encirclement fits, so as to improve the uniformity of cold quantity transmission, improves applicability and utilization rate.
In order to solve the above technical problems, the technical solution adopted in the utility model is：A kind of cold storing bag, including cold-storage list
Inlet is provided with member, the cold-storage unit, the cold-storage unit includes outer wall, the first tunic, the second tunic and inwall, institute
State and thermal insulation layer is provided between outer wall and first tunic, storage is provided between first tunic and second tunic
Cooling layer, the cold-storage layer is connected with the inlet, and agent for storage of coldness, the inwall and the second layer are provided with the cold-storage layer
Heat-insulation layer is provided between film, what the outer wall, first tunic, second tunic and the inwall were formed by hot pressing
Hot-sealing line welding.
Further, the inside outer wall is provided with tinfoil paper composite bed.
Further, the thermal insulation layer in the heat-insulation layer with being each filled with inert gas.
Further, the cold-storage unit is multiple, the hot-sealing line welding that each cold-storage unit is formed by hot pressing.
The utility model has the advantages and positive effects of：Due to using above-mentioned technical proposal, can have well
Deformability, can bend when using, and be fitted being filled with the body surface that can be surrounded when agent for storage of coldness is used with it, so that
The uniformity of cold quantity transmission is improved, the besieged temperature of object everywhere is tried one's best and is consistent.In addition, in use can root
Cut according to being actually needed, so as to improve the applicability and utilization rate of packaging material；It is strong with cold insulation ability, processing cost is low,
Using simple, the advantages of widely applicable.

Embodiment
The utility model is further described with reference to embodiment and accompanying drawing.
As depicted in figs. 1 and 2, the present embodiment is provided is set on a kind of cold storing bag, including cold-storage unit 1, cold-storage unit 1
There is inlet 7, cold-storage unit 1 is included between outer wall 2, the first tunic 4, the second tunic 8 and inwall 9, the tunic 4 of outer wall 2 and first
Thermal insulation layer 6 is provided with, cold-storage layer 5 is provided between the first tunic 4 and the second tunic 8, cold-storage layer 5 is connected with inlet 7, cold-storage
It is provided with layer 5 between agent for storage of coldness, the tunic 8 of inwall 9 and second and is provided with heat-insulation layer 10, outer wall 2, the first tunic 4, the second tunic
8 and the hot-sealing line welding that is formed by hot pressing of inwall 9.
The material of outer wall 2 can select nylon composite materials, and nylon composite materials have stronger anti-voltage endurance capability and relatively low
Cold short coefficient, when ensure that ice bag is squeezed in transportation, do not ruptured because bearing excessive pressure, anti-stagnant ice
Refrigeration unit is spilt in bag.
The inner side of outer wall 2 is provided with tinfoil paper composite bed 3.Tinfoil paper composite bed 3 primarily serves the protection refrigeration unit such as lucifuge, barrier
Effect, with high barrier, be to improve cold insulation ability and the extension cold insulation time provides basis of reality, that is, ensure that ice bag
Cold insulation ability and cold insulation time, chilled goods can be made to be in the environment of low-temperature protection for a long time；The mechanical performance of tinfoil paper composite bed 3
By force, anti-burst performance height, puncture resistant tear resistance are strong, and cold-storage unit 1 can be kept in dark place.
In order to strengthen cold accumulation effects, thermal insulation layer 6 in heat-insulation layer 10 with being each filled with inert gas.
Cold-storage unit 1 is multiple, the hot-sealing line welding that each cold-storage unit 1 is formed by hot pressing.
First tunic 4 is one kind in PET heat-sealings film layer, polyethylene film layer or ethylene vinyl alcohol copolymer body film layer, second
Tunic 8 is one kind in Vingon film layer, polyvinyl chloride or PVA film layer.If the first tunic 4 is that PET seals film layer, correspondence
The film of the second layer 8 is PVA film layer；First tunic 4 is ethylene vinyl alcohol copolymer body film layer (EVOH), and the second tunic 8 is polychlorostyrene second
Alkene；Above-mentioned several high polymers can be mutually combined, and the effect of PET heat-sealing film layers and PVA film layer bonding is optimal：PVA film layer
On the inside of the PET hot sealing layers, PVA film layer can pass through vapor, but can not through organic vapor, inert gas and hydrogen,
With good barrier, PET hot sealing layers have cold insulation, osmotic-pressure-tolerant, play a part of enhancing to ice bag support, and
It is easy to last encapsulation.When using, cold storing bag is put into refrigerator-freezer freezing, then one is placed on the article for needing to refrigerate
Rise, you can realization.
The beneficial effects of the utility model：Due to using above-mentioned technical proposal, there can be good deformability, use
When can bend, and fitted being filled with the body surface that can be surrounded when agent for storage of coldness is used with it, so as to improve cold biography
Defeated uniformity, makes the besieged temperature of object everywhere try one's best and is consistent.In addition, can enter according to actual needs in use
Row is cut, so as to improve the applicability and utilization rate of packaging material；Strong with cold insulation ability, processing cost is low, using simple, is applicable
Wide the advantages of.
One embodiment of the present utility model is described in detail above, but the content is only of the present utility model
Preferred embodiment, it is impossible to be considered as being used to limit practical range of the present utility model.It is all to be made according to present utility model application scope
Equivalent change with improve etc., all should still belong within patent covering scope of the present utility model.
