Abstract
The utility model provides a disposable meal box heated by oxidizing iron powder. The disposable meal box is characterized in that an iron powder bag is attached to the bottom of the disposable meal box; a triggering layer is attached to the iron powder bag; and a tearing membrane covers the triggering layer. When a user tears off the tearing membrane at the bottom of the disposable meal box, the triggering layer, formed by substances including active carbon, water, inorganic salt and the like, contacts air and triggers the iron powder in the iron powder bag to be subjected to redox reaction to generate heat so as to continuously heat the disposable meal box, so that dishes are still hot when being eaten; and the production cost of the disposable meal box is very low.
Description
Technical field
The utility model relates to a kind of disposable lunch-box, particularly a kind of disposable lunch-box with the iron powder bag.
Background technology
Have a dinner in restaurant packing or take out and all need to use disposable lunch-box, if but cold weather or standing time, long very fast food was just cool, a lot of dish in cold after again heat can affect mouthfeel, such as fried food, so the lunch box that can heat is the problem of receiving solution.The oxidation of iron powder reduction reaction has been that mature technology uses in life extensively, utilizes exactly this principle such as warm baby's heating paste, so utilize the oxidation of iron powder technology to come to heat very feasible for disposable lunch-box.
Summary of the invention
The purpose of this utility model is exactly to solve the problem of mentioning in the above-mentioned background technology, and a kind of oxidation of iron powder heating disposable lunch-box is provided.
The technical solution adopted in the utility model is: oxidation of iron powder heating disposable lunch-box, it is characterized in that: at disposable lunch-box Bottomattached iron powder bag, iron powder is wrapped and is adhered to trigger layer, covers peelable film on the trigger layer.
The beneficial effects of the utility model are: when the user tears the peelable film of disposable lunch-box bottom, trigger layer and contact with air, trigger layer is comprised of active carbon, water, inorganic salt and other material, the iron powder generation redox reaction that trigger layer will trigger in the iron powder bag produces heat then, can be constantly the disposable lunch-box heating, be still the Hot dishes meat and fish dishes when taking food, production cost also and cheap.
Description of drawings
Below in conjunction with accompanying drawing and example the utility model is described in further detail.
Figure is structural representation of the present utility model.
Among the figure: 1, disposable lunch-box, 2, the iron powder bag, 3, trigger layer, 4, peelable film.
The specific embodiment
Such as figure, oxidation of iron powder heating disposable lunch-box, it is characterized in that: at disposable lunch-box 1 Bottomattached iron powder bag 2, adhere to trigger layer 3 on the iron powder bag 2, cover peelable film 4 on the trigger layer 3, when the user tears the peelable film of disposable lunch-box bottom, trigger layer and contact with air, trigger layer is comprised of active carbon, water, inorganic salt and other material, the iron powder generation redox reaction that trigger layer will trigger in the iron powder bag produces heat then, can be constantly for the disposable lunch-box heating, be still the Hot dishes meat and fish dishes when taking food, production cost also and cheap.
