Description

Light lunch box

Technical field

What the present invention relates to is a kind of lunch box, especially a kind of " vacuum glass (tea glass liner box or lucite box) incubation canteen " and a kind of " lunch box of ability electric power storage heating ".

Background technology

At present, various various lunch boxes are arranged on the market, and the incubation canteen of higher gears is arranged.The low price that these lunch boxes have can not be incubated, though can being incubated of having, temperature retention time has only 1-2 hour, and price is not cheap yet.They all have a common shortcoming, the suitable temperature in the time of can not satisfying owner exactly and have a meal dish.Promptly be that high-grade incubation canteen also is about 1-2 hour.If also can't satisfy in that 1-2 hour winter.This is very difficult concerning the people of many use lunch boxes solution lunches, and they are difficult to be able to eat the food of satisfied suitable temperature.If use existing incubation canteen, insulation also can only be about 1-2 hour, and the time has been grown, and can cool off, and it is very uncomfortable to taste.Just investigate, many rural migrant worker's workings, the pupil of outlying mountain area goes to school, and worker's working in the time of zero solves lunch through unsatisfied lunch box commonly used.But, adhering to peasants for a long time at rural labor, they in order to race against time, did not take into consideration to go home to cook to eat from the work in morning when the busy farming season, went home just knock off evening, can't solve lunch easily, have to eat two meals in one day.Town and country primary school particularly in order to solve lunch, has carried out unified charge and has solved lunch, has caused certain influence to society, and the one, increased the head of a family's burden, the 2nd, exist a great potential safety hazard.If better incubation canteen is arranged, be crucial to them.

Summary of the invention

In order to address the above problem, the present invention has developed a kind of " vacuum glass heat-insulating lunch box " and a kind of ability " electric power storage heating lunch box ".Be called for short by " light lunch box ".It can solve various people lunch box easy to use and solve lunch.They can spend less, oneself are with " light lunch box ", to when eating lunch, can be able to eat the food of the satisfied suitable temperature that own ready heat inspires confidence in.Alleviated a potential safety hazard of imposing unified dining room of financial burden and school greatly.

The specific embodiment

Owing to had such scheme, the present invention to use following mode to implement.

Category-A: " vacuum glass heat-insulating lunch box "

1, its exceptionally box and inner box (tea glass liner box or lucite box);

2, the outer box of employing overlaps inner box and can protect inner box.Outer box can attach the plastic casing of effect, also available metal box with nontoxic nothing preferably.Inner box is vacuum glass (tea glass liner box or lucite box) incubation chamber.

3, the thin foam of outer box inwall Ansai one deck, lunch box in the protection.Not clashing and breaking easily of lunch box (can substitute) in making if diminish.

4, lunch box specification and shape are complied with elegant in appearance and are designed, and are good with " cylinder " or " elliptic cuboid " generally, and established 1-3 the lattice (or layering) that inner box is big supplies to fill a bowl with rice vegetable soup.

5, the lid of vacuum glass heat-insulating lunch box divides inner cap and enclosing cover, and inner cap can be sealed food soup and be difficult for outer rushing down, and the whole lunch box of enclosing cover ability fastening can not be opened easily.For ease, also can the inner cap enclosing cover be combined into a lid.

6, the temperature retention time of " vacuum glass heat-insulating lunch box " is generally at 8-10 hour, the suitable temperature in the time of can supplying lunch fully (50 ℃-70 ℃).

When 7, using, directly open the food that lid just can be able to eat suitable desirable temperature.

Category-B: " electric power storage heating lunch box "

1, lunch box comprises inner box and outer box, outer box cover inner box.Outer box plate is provided with electric power storage, switch, heating element electrical equipment settings such as (plate, dishes), the established 1-3 lattice (or layering) that inner box the is big millet paste that is used for filling a bowl with rice, and inner and outer box also can be integrated.
