Abstract
Disclosed is a self-heated cutlery box, which comprises: outside box, inner container, water bag and calcia heating bag. The inner container is installed in the outside box and has double-layer box structure, wherein a gap between layers, under the gap is the heating device equipped with the water bag and calcia heating bag; on the water bag and calcia heating bag are separately equipped with opening devices which tear strips extend out from one side of the heating device.
Description
Technical field
The invention belongs to cooker, is a kind of from heating lunch box specifically.
Background technology
The lunch box that uses is various box body structures at present, can not heat voluntarily.Particularly travel and the heating of field work person's lunch is the part pain in the neck for numerous working clans worker, student, driver, make the special use lunch box of heating, allowing people can have hot rice and dish at any time is the problem that people are paying close attention to always.Chinese patent discloses a kind of lunch box of heating voluntarily that is formed by lunch box body and heater combination, and (application number is: 86209530), utilize the coal briquette burning that food is heated the effect that can keep higher temperature within a certain period of time of playing, heater is provided with aerofoil, can regulate the size control coal briquette burning velocity of fresh air inlet, the coal briquette that burns can make temperature 4-5 hour of about 70 ℃ of lunch box maintenances.Weak point is: lighting with kindling material when edible can heat food, uses inconvenience.
Other has a kind of constant temperature electrical heating lunch box of the PTC of utilization semiconductive ceramic electric heating element, and (application number is: 87215952), when temperature rises to about 110 ℃ in lunch box, can fall end electrical power automatically, make lunch box be in temperature constant state, avoid sticking with paste meal.Weak point is: use having under the condition of power supply, can not use in the open air, be subjected to environmental limitations.
Also have a kind of can (application number is: 92245336.5), it be that box mouth periphery at box body studs with sealing strip, can seal with lid that periphery is shaped on the tang limit to combine from heating, fresh-keeping lunch box; The box body bottom is provided with the protruding chamber of sealing, and solid burning block and end cap are housed in the chamber, constitutes self heater; Lid also is equipped with air bleeding valve.Weak point is also to have the kindling material problem.
Particularly have a kind of 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 5～10 millimeters.But carry inconvenience, to open inconvenience unreliable again.
Summary of the invention
The object of the present invention is to provide a kind of lunch box of heating certainly flexible, simple in structure, applied range of opening.
To achieve these goals, technical scheme of the present invention is: comprise outer box, inner bag and water bag and calcium oxide heating bag, inner bag is contained in the outer box; It is characterized in that: inner bag is double-deck box structure, being provided with at interval between layer and the layer, is heater below at interval, in be placed with water bag and calcium oxide heating bag, be provided with opening device on described water bag and calcium oxide heating bag, the tear band of opening device passes from a side of heater;
Described opening device structure is for to have cut line on the heat seal face of bag, the heat seal face free end at cut line place is connected to tear band, and tear band passes from heater one side;
Described being spaced apart do not have anti-cloth; Described opening device number can be 1-2; Described inner bag has openable loam cake, covers on it to be provided with the hole; Described outer box is a degradation material; The heat seal face place at described cut line place can be provided with fastener.
The present invention has following advantage:
1. convenient the unlatching.The lunch box of heating certainly that the present invention proposes has improved opener, and easy to carry, unlatching is convenient reliable again, can increase substantially the flexibility of use.
2. the flames of anger, safe and reliable.Get final product heat food after lighting without kindling material when edible, do not have the kindling material problem; Can use under non-transformer, anhydrous condition, can be in the open air, the disaster area uses, and is not subjected to environmental limitations.
3. easy to use, with low cost.The present invention can disposablely use, and common people are acceptant on price.In addition, the recyclable coating of doing of lime in the calcium oxide heating bag with mistake, its outer box adopts degradation material (corn tangerine, paper pulp) to make, and has the environmental protection characteristics.
4. the present invention is rational in infrastructure, the food of adorning adopt high temperature sterilization, vacuum packaging can fresh-keeping storage of long period.
5. of many uses.The present invention can be for numerous workers, student, old man, children, driver, particularly tourism and the daily use of the field work person of army.
