Abstract

The utility model provides a cold -storage wrapping bag, includes a bag section of thick bamboo that is formed by the bag wall, forms in a bag section of thick bamboo and puts the object space, wherein the bag wall is multilayer structure, contains cold -storage layer and cold insulation layer in the bag wall. Set up the stock solution room of filling the cold -storage agent in the cold -storage layer, store cold volume through the cold -storage agent, it can in the object space putting of wrapping bag only to need to place article when using, release the low temperature that cold volume keeps putting the article of depositing in the object space gradually through the cold -storage agent, make for the bad conductor of heat on the cold insulation layer, the setting is outside the cold -storage layer, and with cold -storage layer cladding, thereby slow down the speed that cold -storage agent and external environment in the cold -storage layer directly carry out the heat exchange, thereby the cold volume of extension cold -storage agent prolongs the cold insulation time of putting the interior article of object space promptly deenergized period. The utility model has the advantages of simple to use, wide applicability, the posterior annulus of the cold chain logistics festival can be fully solved and in the problem that exists on current phase, different article have been satisfied in low -temperature preservation and transportation demand.

Description

Cold-storage packaging bag

Technical field

This utility model relates to the technical field of Cold Chain Logistics, specifically a kind of convenient cold-storage packaging bag used.

Background technology

Agent for storage of coldness is usually a kind of thickness colloidal mixture being made up of organic or inorganic compound, can absorb at low temperatures and store a large amount of cold, and a large amount of cold can be released when temperature is higher, it is possible to the low temperature environment in long period maintenance self and around little scope.

The subject matter existed in the cold chain transportation fields such as food and medicine vaccine is the chain rupture of cold chain link, the wholesale market that food and medicine reach market through place of production pre-cooling loading transport vehicle finally enters retail link storage, all easily occurs the chain rupture of cold chain in these links. Agent for storage of coldness is used can effectively to solve be pre-chilled to transport vehicle from the place of production and arrive the problem run into the storage of retailer and retailer and the problem solving to run in food and medicine transportation from wholesale market, solve the fluctuation of food and medicine storage temperatures, realize the seriality of reserve temperature, the quality of maximized control product, improves added value.

Agent for storage of coldness is normally encapsulated in hold-over plate and uses, hold-over plate of the prior art is all designed to the platy structure of cuboid, and different according to specifically used purposes, hold-over plate is processed into again various different volume, but hold-over plate of the prior art is general thicker, cause in-convenience in use. When coordinating transport cases to use, traditional hold-over plate can only be placed on the surface being transported object and surrounding, causes cold quantity transmission in casing uneven, if needing the article kind transported comparatively various in cold chain transportation process, or laying for goods irregular time, disadvantages mentioned above then becomes apparent from. It addition, traditional hold-over plate is only suitable for the transit link in Cold Chain Logistics, it is impossible to be applied to daily life, namely general consumer cannot contact and use. In the least significant end link of Cold Chain Logistics, the article of Keep cool the state of needs still cannot successfully freely be shifted by consumer, also need to pack by the cold closet of inconvenience use, couveuse etc. when item transfer.

Detailed description of the invention

Referring to drawings and Examples, this utility model is described in detail.

As shown in Figure 1 to Figure 3, cold-storage packaging bag of the present utility model, including the bag cylinder formed by bag wall 1, in bag cylinder, form material-putting space 2, bag wall is multiple structure, is provided with cold-storage layer and Cold-keeping Layer. According to the difference using environment, bag wall can arrange multiple cold-storage layer and multiple Cold-keeping Layer simultaneously, thus strengthening cold insulation effect.

Above-mentioned cold-storage layer includes the first adventitia 3 and the second adventitia 4, and outside the first adventitia and second, the multiple mutual separation of intermembranous formation sealing are filled with the fluid reservoir 5 of agent for storage of coldness. In order to ensure that cold-storage packaging bag can occur enough deformation, the first adventitia and the second adventitia all to adopt flexible material in use, for instance plastic sheeting etc. First adventitia and the second outer intermembranous hot-sealing line 6 welding formed by hot pressing, form multiple fluid reservoir 5 between hot-sealing line.The fluid reservoir arranging multiple separation in cold-storage layer can make the agent for storage of coldness of whole cold-storage layer be distributed more uniformly, reduces owing to gravity or external force extrude the agent for storage of coldness caused skewness in fluid reservoir, thus improve the cold insulation effect of cold-storage packaging bag.

Bag wall is extremely set gradually outward inner wall layer 7, cold-storage layer 10, Cold-keeping Layer 12 and outer wall layer 8 by internal material-putting space. Inner wall layer, cold-storage layer, Cold-keeping Layer and outer wall layer are adhesively fixed successively, Cold-keeping Layer is coated on outside cold-storage layer, by the cold insulation pad being made up of flexible cold insulation material, cold-storage layer and external environment are separated, reduce agent for storage of coldness as far as possible and carry out direct heat exchange with external environment, to improve the cold deenergized period of agent for storage of coldness. Flexible cold insulation material is also widely used in the prior art, utilizes cold insulation material to make the cold insulation pad of thinner thickness in this utility model, reduces heat transmission by cold insulation pad.

Inner wall layer 7 and outer wall layer 8 adopt comparatively flexible and solid material, improve the firmness of packaging bag, thus protecting the fluid reservoir in cold-storage layer by external items or load the article scuffing of packaging bag and pierce through.

The bag underseal of cold-storage packaging bag closes, and bag mouth place arranges sealing structure. After article are encased in the material-putting space of cold-storage packaging bag, can close sealing structure, thus improving article cold insulation effect in cold-storage packaging bag and cold insulation time. Sealing the enclosuring structure that structure can adopt existing normal packet to pack, the sealing structure of relevant bag mouth belongs to the technical staff in packaging bag field and is readily able to the usual structure expected.

The sealing structure adopted is such as: the structure shown in Fig. 1, and the bag cylinder of wherein side, bag mouth place upwards extends formation pkt. flap 9, pkt. flap arranges adhesive tape 11, after inserting article, by pkt. flap to bag cylinder with opposite side after lateral buckling is bonding, and is sealed by bag cylinder.

Or arrange self-styled clip chain at bag mouth place, bag cylinder is sealed by self-styled clip chain.

Or bag mouth place arranges slide fastener, by slide fastener, bag cylinder is sealed.

The above-mentioned self-styled clip chain in bag mouth setting or slide fastener are all structure of the prior art, therefore not shown.

The above, it it is only preferred embodiment of the present utility model, not this utility model is done any pro forma restriction, although this utility model is with preferred embodiment openly as above, but, it is not limited to this utility model, any those skilled in the art, without departing within the scope of technical solutions of the utility model, certainly the technology contents of announcement can be utilized to make a little change or modification, become the Equivalent embodiments of equivalent variations, in every case it is the content without departing from technical solutions of the utility model, any simple modification above example made according to technical spirit of the present utility model, equivalent variations and modification, belong in the scope of technical solutions of the utility model.
