Abstract
The invention relates to a packaging method of self-heating food. Aims to solve the problems that the heat of the self-heating food in the soft package is easy to dissipate, the heating effect is poor, the food in the inner package is easy to extrude, agglomerate and cake, and the like. The present invention adopts aluminium cuboid container to fill food, and the container is divided into two chambers by means of aluminium partition. The aluminum container has a pull ring on the upper surface for opening, and is externally sleeved with a light and high-barrier heat-insulation engineering plastic container with the same shape, wherein a plurality of inward-protruding plastic supporting legs are attached to four side surfaces and the bottom surface of the plastic container, and 4 supporting legs are respectively arranged at four corners of each side surface; the bottom surface is respectively provided with one at four corners and the middle part. The plastic container is slightly higher than the aluminum container, is just placed in and clamped by the aluminum container, and is provided with a turnover cover. The gap between the two is filled with magnesium-iron powder uniformly, then a sealing strip with a pull tab is embedded, and the sealing strip is welded by using viscose glue. The flip cover of the plastic container is put down and clamped, and the outside is packaged and printed by a flexible packaging film with high air tightness.
Description
Affiliated technical field
The present invention relates to method for packaging food, particularly from the packing of heated food.
Background technology
At present, from the packing container of heated food, mainly be the flexible packaging plastic bag.Inner packing has the rice or the noodles of plastics retort pouch or In Aluminium Foil Packing, perhaps dish, and both sides respectively attach the fiber papery heating plate of a filling magnesium-iron powder, outsidely pack with the air-tightness plastic bag.Owing to be to adopt flexible packaging, from heated food in transportation, storage process, often owing to be squeezed; Cause agglomerating caking, rice becomes rice cake, noodles to become dough, influences the food sense organ; And because tissue tight is solid after agglomerating, be unfavorable for conducting heat, influence eating effect.Because outer packaging bag does not almost have heat-proof quality, can cause scattering and disappearing of heat simultaneously, especially in the lower field of ambient temperature, heats is poor.In addition, because the barrier property of soft packaging bag is not enough, tend to cause the slow loss of food water, quicken the sclerosis of rice, noodles in the packing, influence mouthfeel, the magnesium-iron powder generation deferred reaction in part moisture and the heating bag makes the termite deleterious simultaneously.
Summary of the invention
In order to overcome existing drawback from the heated food packing, the present invention provides a kind of new packing method from heated food.Adopt the flat square of aluminum or be similar to the cuboid container filling food (rice or noodles etc.) of square, there is an aluminium matter sheet in these internal tank central authorities, and this container is separated into two Room, are convenient to conduct heat.About 3 centimetres of this aluminium vessel height, upper surface has a draw ring, is convenient to open.Aluminum food containers outer cover is pretended with the lightweight of shape and tool high barrier engineering thermal insulation plastic container; Other four sides and the bottom surface of these plastic container except that upper surface is all with column type (or taper) the plastic support pin of several inwardly outstanding diameter 3 millimeter; 4 feets can be established in each side, are located at four jiaos respectively; Respectively establish one except that four jiaos the bottom surface, and the middle part is established one.About 0.5 centimetre of feet length, the size of plastic container is packed into just and is blocked aluminium vessel, and feet and plastic container fuse and play fixation, prevent that food containers from sliding in plastic container.Plastic container are slightly higher than aluminium vessel, and have one and renovate.Magnesium-iron powder is evenly filled in gap between aluminium vessel and plastic container (gap and bottom gap all around), and will have the sealing band that draws tongue then and around the upper surface of aluminium vessel, embed, and with viscose glue welding, magnesium-iron powder that sealing has been filled.Renovating of plastic container put down and withheld, and packages printing is carried out with the high contraction flexible packaging film of air-tightness again in the outside.When edible, tear wrapping film, raise buckle, open and renovate; Hold the tongue that draws of sealing band, firmly draw back 3 centimetres of left and right sides length of sealing band, suitable quantity of water is injected the gap that is filled with magnesium-iron powder, and the sealing band that draws back is resetted, links closely; Put down plastics and renovate and fasten, stir entire container gently, make the water and the magnesium-iron powder uniform contact of injection, exothermal reaction takes place; Just can realize the food heating, firmly draw back the draw ring of aluminium vessel, with regard to edible.
The aluminium vessel that the present invention adopts is in light weight, and it is fast to conduct heat, owing to adopt square, the contact thermal face area is maximum, and central authorities are provided with an aluminum partition, and container is separated into equal-sized two Room, and it is more even to conduct heat.High barrier engineering thermal insulation plastic container, light weight, air-tightness is good, and adiabatic heat-blocking action is strong, can effectively reduce the thermal loss of self-heating agent, and can not scald one's hand.Because this project plastic container have intensity preferably, can protect inner packing food not to be squeezed, food can agglomeratingly not lump, and rice can not become a meter cake, noodles can not become dough, so the food sense organ is good.This repeatedly recycling use of engineering thermal insulation plastic container helps energy-conserving and environment-protective.
Claims (5)
1. packing method from heated food adopts the adiabatic plastic container of the outside suit of aluminum food containers and between two containers, fills the method packaged food of termite.
2. according to right 1 described a kind of packing method, it is characterized in that the aluminum food containers is flat square or is similar to square, and have an aluminium matter partition that this container is separated into two Room in this container from heated food.
3. according to right 1 described a kind of packing method, it is characterized in that other four sides and the bottom surface of adiabatic plastic container except that upper surface is all with several inwardly outstanding plastic support pin from heated food.
4. according to right 1 described a kind of packing method, it is characterized in that adiabatic plastic container and aluminum provision room filling termite from heated food.
5. according to right 1 described a kind of packing method, it is characterized in that engineering thermal insulation plastics tool high barrier and repeated use capable of circulation from heated food.
