Description
Technical field
The present invention relates to food packaging applications, are related specifically to a kind of disposable self-heating incubation canteen.
Background technology
Nowadays take out food delivery has turned into a kind of universal mode of having dinner, and it has been saved the time for the life of people and brought
It is convenient.But occur that canteen has cooled when canteen is dispatched into client's hand when it is cold often, the canteen cooled not only influences mouthfeel, food
It is intended to also be unfavorable for health to a certain extent, resulting complaint does not also occupy the minority with dispute.At present, it is public in patent gazette
The disposable lunch box species opened is various, but plays the more based on use foam heat-insulation layer, tin film layer of insulation effect, and this mode makes
Canteen does not have an external heat source heating, heat insulation effect is bad；A kind of another self-heating type quick-meal box having in CN2016101400299
In, substantial amounts of water need to be added into self-heating powder, make self-heating powder it is submerged in water produce very exothermic reaction, make lunch box stand one section when
Between, to heat canteen, but this mode can not make a person sponging on an aristocrat eat the canteen sent immediately also to heat waits, be not suitable with now
Fast pace life, less sending with charge free suitable for canteen.The drawbacks of how overcoming prior art, design is a kind of to carry thermal source once
Property incubation canteen turn into the present invention research object.
The content of the invention
The problem of existing present invention aim to address prior art, a kind of disposable self-heating insulation for carrying thermal source of design
Lunch box.
The technical proposal of the invention is realized in this way；A kind of disposable self-heating incubation canteen, including lunch box box body, it is special
Sign also includes from thermosphere, air exclusion film, described to be close to lunch box cartridge outer surface from thermosphere, is set respectively from the inside to the outside from thermosphere
In respect of band glue-line, self-heating powder, ventilated membrane, nonwoven layer, flanging processing is done from thermosphere outward flange, self-heating powder is fixed on band glue-line
With ventilated membrane, nonwoven layer flanging into bag in, from thermosphere outer patch close have a layer of air secluding film, by self-heating powder outwardly one
Face and air exclusion, to prevent self-heating powder air inlet and the oxidation reaction of air heat release.Wherein band glue-line is using airtight
Material, make the another side and air exclusion of self-heating powder, equally play the oxidation reaction to prevent self-heating powder from playing with air heat release.
Band glue-line is towards lunch box box body one side covered with viscose glue, and to be bonded with lunch box box body, band glue-line covers towards self-heating powder one side
There is water-soluble glue, water-soluble glue makes self-heating powder equably be attached to band glue-line.
Further, the ventilated membrane uses porous PE films or porous aluminium-foil paper film or porous evaporation aluminium film, porous
Structure can admit air into ventilated membrane and be reacted with self-heating powder, and aluminium-foil paper or porous evaporation aluminium film can block self-heating powder adstante febre
Heat radiation outwards transmit, preferably preserve the heat of self-heating powder and canteen itself.
Further, self-heating powder is made up of iron powder, water, active powdered carbon, vermiculite power, sodium chloride, active powdered carbon and vermiculite power
On the one hand on the other hand iron powder and sodium chloride uniformly dispersing are utilized into the extremely strong water imbibition of active powdered carbon and vermiculite on band glue-line
The moisture in air is fully absorbed to help sodium chloride to accelerate the exothermic oxidation reaction of catalysis iron powder and the oxygen in air, so as to
The appropriate speed for accelerating exothermic oxidation reaction.
Further, for ease of easily using, for example each edge in relevant position on air exclusion film, which is provided with, tears angle.
The outermost air exclusion film of lunch box is torn by tearing angle during use, now air permeable nonwoven layer, ventilated membrane and self-heating
Powder contacts, and it is anti-that oxidation heat liberation occurs under water and catalyst sodium chloride collective effect with the iron powder in self-heating powder for the oxygen in air
Should, its caused heat transfer serves the effect of self-heating insulation to the canteen in lunch box.
Further, described air exclusion film is opp films or pet films or glassine paper.
Further, the present invention also may be designed to the single lunch box self-heating guarantor that self-heating heat-insulation layer separates with lunch box box body
Temperature set.
In addition, the speed that can control oxygen to enter self-heating bisque by changing the density of stomata on ventilated membrane, so as to control
The speed of exothermic oxidation reaction, change from thermosphere exothermic temperature and heat release duration.To reach higher resource utilization, play most
Good heat insulation effect, at the same it is again unlikely hot, can be by temperature control between 40 DEG C -50 DEG C, heat release duration was controlled at 4 hours
Left and right.
The present invention has the characteristics of being skillfully constructed, be reasonable in design, cost is cheap, exploitativeness is strong, practicality is high, changes
The drawbacks of traditional disposable lunch box poor thermal insulation property, it substantially prolongs insulation duration, improve heat insulation effect, overcome existing one
Secondary property incubation canteen is not suitable with present fast pace life, is disposable heat-preserving rice less suitable for canteen the shortcomings that sending with charge free
The research and development of box provide new thinking.
In order to better illustrate the present invention, with reference to specific embodiment and embodiment accompanying drawing the present invention is done into
One step explanation.
