Abstract
A portable self-heating sack includes heating sack, non-woven fabric sack and aluminum-water heating agent. The aluminum-water heating agent is comprised by aluminum, accelerant containing alkali material, depressant containing soluble oil material, and is completely powdered, in this manner, heat generation speed can be accelerated and high temperature can be obtained. The heating agent is packed in hydrophilic double-layer composite non-woven fabric grid, so that external surfaces of the heating sack and food sack is undefiled during the affusion activating procedure and a procedure of heat generation for heating food. The self-heating sack making in this manner has advantages of low cost, easement for use and carrying, quick heating, high temperature.
Description
Technical field
The present invention relates to a kind of packaging bag, particularly relate to and a kind ofly pack from heat packs.
Background technology
At field of food, be used to heat edible food and will use cooker usually, for numerous working clans worker, student, driver particularly travel and field work person extremely inconvenient as the outdoor diet of soldier or the like, make special-purpose heating apparatus, allowing people can have hot rice and dish is the problem that people are paying close attention to always.Have a kind of on the market from heating convenient mess tin, (application number by: 86209453) formed by outer box, lid, fixed support, rotation handle, inner bag, pyrogenicity agent, leave the space between box and the inner bag outside, be provided with removable water bag and calcium oxide heating bag outside in the space between box and the inner bag, weight ratio is a water: the side calcium oxide: calcium oxide=1: 1: 1.6 is put at the end, calcium oxide must be broken, and its granularity is the 5-10 millimeter.But carry inconvenience, to open inconvenience unreliable again.In addition, on December 06th, 2006, a kind of application number of bulletin was: 200510046562.0 the disposable lunch-box with self heating function, comprise outer box, inner bag and antifreezing agent bag and calcium oxide heating bag, though that this device has is anti-scald, also can heat advantages such as use under freezing situation, also there are shortcomings such as the temperature of structure check, manufacturing cost height, heating not high (maximum temperature generally not can above 95 ℃) in this device.Above-mentioned all deficiencies of the present invention and shortcoming, design a kind of have easy to use, cost is low, the portable self-heating bag of heating-up temperature advantages such as high (maximum temperature surpass 100 ℃, can high-temperature sterilization).
Summary of the invention
The objective of the invention is to provide a kind of and existing self-heating apparatus to compare the self-heating bag that cost is low, easy to use, heating-up temperature is high.
In order to realize purpose of the present invention, a kind of packaging bag provided by the invention comprises heating bag, non-woven bag and aluminium water type thermit powder composition.Wherein, aluminium water type thermit powder is made up of aluminium, the promoter that contains the highly basic material, the inhibitor that contains the oil emulsion material; The complete powderization of aluminium water type each composition of thermit powder, long-pending to enlarge chemical reaction surface; In the thermit powder composition, add the promoter that contains the highly basic material, be convenient to quicken abolishing of aluminium powder surface film oxide, promote aluminium and aquatic products thermal response to take place as early as possible; In the thermit powder composition, add the inhibitor that contains the oil emulsion material, suppress flying upward and scattering of powder; What of aluminium water type thermit powder are determined according to what of the food of required heating; In addition, non-woven bag is to adopt hydrophily dilayer compounding non-spinning fabrics composition and be divided into several lattice (what decide the food how many bases of lattice number will heat), like this so that the aluminium water type thermit powder that is contained in the non-woven bag is easy to suction and permeable, thereby further accelerate exothermic reaction speed, and guarantee that dry mash does not leak outside, wet slurry does not efflux.
Beneficial effect of the present invention is: owing to adopted aluminium water type thermit powder, heat production is fast, temperature is high and by nonwoven lattice packing, and aluminium water type thermit powder powdering, causes heating bag closely and stiffening, and powder does not leak outside substantially, carries with easy to use; When water filling starts and in the heat production packaged food process, heating bag and food bag outer surface all are clean.
Purpose of the present invention, feature and advantage will be in conjunction with the embodiments, are further described with reference to accompanying drawing.
Description of drawings
Fig. 1 is an embodiment of the invention sectional plan view.
Fig. 2 is an embodiment of the invention side view.
Fig. 3 is that configuration schematic diagram is used in embodiment of the invention heating
The specific embodiment
Heating bag 1 shown in Fig. 1,2 is made of non-woven bag 2 and aluminium water type thermit powder 3.Non-woven bag 2 can be the double-deck terylene fabric hot rolled nonwoven fabrics/polyethylene powder composite through hydrophilic treated.It also can be the terylene fabric hot rolled nonwoven fabrics/polyethylene powder/polypropylene fibre fabric hot rolled nonwoven fabrics composite of hydrophilic treated.Aluminium water type thermit powder 3 is mixtures of industrial aluminium powder and basic matterial, and granularity adopts the lattice packing usually in 40 orders ~ 200 order scopes.Bag limit 4a and lattice lateral road 4b can adopt low frequency heat seal or supersonic thermal setting mode to seal.For preventing that bag limit 4a opening from can also adopt the sewing mode to reinforce four limits.The storage of heating bag 1, protection against the tide is sealed up for safekeeping in the bagging 6 of should packing into.When heating was used, as shown in Figure 3, heating bag 1 preheating packaged food 5 all was seated in the bagging 6, and heating bag 1 is in the following orientation of food 5.The reaction water of injecting in the bagging 6 from the outside 7 flow to a bag bottom, are absorbed by non-woven bag 2 very soon, and in time are impregnated into thermit powder 3 inside.The aqueous alkali that water and basic matterial produce is abolished the aluminium powder oxidation film, and then aluminium water oxide etch exothermic reaction takes place.The centre highest temperature of thermit powder can reach about 120 ℃, and has vapours and hydrogen to produce.At this moment, the food 2 of bagging 6 inner close fitting heating bags 1 is heated very soon.Because the heating bag material is the dilayer compounding non-spinning fabrics structure, it has filterability and aeration, and bag internal reaction article 5 surfaces do not have white pollution yet.
During the utility model heating operation, the bagging 6 of tear initiation packing heating bag 1 and food 5 suitable for reading; In bagging 6, inject quantitative reaction water 7 again: in time swing bagging 6 integral body, impel reaction water 7 uniform opening; Then the covering food 5 on the inflection bagging 6 above, bagging 6 integral body are kept flat: after leaving standstill more than ten minute, take out food 5 and open bag heat food.Operation as stated above, the utility model thermit powder loading amount 20g, the pre-hot packing dish or food of heating 300g injects the 40ml reaction water, and the dish or food temperature can reach more than 70 ℃ about 12 minutes.
Claims (2)
1, a kind of portable self-heating bag comprises heating bag, non-woven bag and aluminium water type thermit powder.Wherein, aluminium water type thermit powder is made up of aluminium, the inhibitor that contains the oil emulsion material; Non-woven bag is made up of the hydrophily dilayer compounding non-spinning fabrics that is divided into several lattice.
2, according to self-heating bag in the claim 1, the complete powderization of wherein said aluminium water type each composition of thermit powder, what of aluminium water type thermal dose are determined according to what of the quantity of food of required heating.
