Abstract
The utility model relates to a heat-preserving and fresh-keeping box, comprising a box body and a box cover, wherein, the box body comprises double layer walls, and thermal-insulating and heat-preserving materials are filled between the two layer walls; a heat-preserving layer is arranged inside the box cover, and a sealing and connecting mechanism is arranged between the box body and the box cover. The box body and the box cover can be made by adopting materials such as stainless steel, etc. The heat-preserving and fresh-keeping box has the advantages of good heat-preserving and fresh-keeping effects, convenient carrying, and uneasy breakage.
Description
The utility model relates to a kind of lunch or picnic box or analog.
With the immediate prior art of the utility model is to seal lunch box, and it mainly is made up of sealing ring between box body, lid and box body and lid and elasticity card.What mainly solve is the problem that leaks outside of the thing of adorning in the box, does not have the effect of heat preserving antistaling.When people are on duty work, during field work, when outing are picniced etc., be with sufficient food.Ordinary lunch-box, has not only been wasted the energy, and the nutrition of food is incurred loss so food will heat in edible again owing to do not possess heat insulation function, influences taste etc.Particularly do not having under the situation of heating condition, the eater have to cold food, and influences healthy.The prior art approaching with the utility model also has thermos flask, and it is the conduction that solves heat by vacuumizing between the double glazing wall, solves hot auxilliary penetrating at the silver that applies on glass.Thermos flask is easily broken, and sealing property is bad, and is not portable etc.
The purpose of this utility model is to provide a kind of heat preserving antistaling effective, cracky not, heat preserving antistaling box easy to carry.
The purpose of this utility model is achieved in that it comprises box body and lid, and box body is made of double wall, is filled with heat-insulating material between the two layers of walls, also has heat-insulation layer in the lid, and mechanism is tightly connected between box body and the lid.
It also comprises following architectural feature the utility model:
Vacuumize between the double wall with box body, in the bottom of box body outer wall vacuum orifice is arranged, the bottom of outer wall has a base.
Being provided with one can be hung on box body place suitable for reading and place the interior auxilliary box body of box body.
One handle is set.
The advantage of the utility model is: box body and lid can adopt materials such as stainless steel, aluminium to make.Filling heat insulator between the double wall of box body also has heat-insulation layer in the lid, its insulation, fresh keeping property are good.As with the vacuum below degree of the being evacuated 20Pa between the double wall of box body, the heat preserving antistaling effect is better, and 95 ℃ food is packed in the box, under the condition that environment temperature is 15～20 ℃, keeps 6 hours, and temperature still can reach 50 ℃ in the box., under the condition that environment temperature is 30 ℃, kept 6 hours in the box if cold system food of the general-18～-20 is packed into, temperature still can reach-5 ℃ in the box.Preserving fresh milk, fresh fruit never degenerates within 3 days.Between box body and lid, be provided with the mechanism that is tightly connected, not only strengthened insulation, fresh-keeping effect, and be easy to carry.
Accompanying drawing is the structural representation of preferred embodiment of the utility model.
In conjunction with the accompanying drawings, box body 1 all adopts stainless steel material to make with lid 2.Box body 1 is made up of double wall, is filled with heat-insulating material 3 between two walls, and degree of being evacuated is provided with vacuum orifice 4 less than 20Pa in the bottom of box body 1 outer wall, has check valve and filter on the vacuum orifice 4, mouth is sealed after exhausting vacuum.In order to prevent the damage of vacuum orifice 4, be provided with a base 6 in the bottom of outer wall.The place suitable for reading of box body 1 is arcuation.The inside of lid mouth is provided with heat-insulation layer 7, and heat-insulation layer 7 is made by non-toxic plastic.It also comprises auxilliary box body 8.There is the arcuate structure that matches suitable for reading with box body 1 at the place suitable for reading of auxilliary box body 8.Auxilliary box body 8 can be hung on the place suitable for reading of box body 1 and place in the box body 1.Mechanism is tightly connected between box body 1 and the lid 2.Sealing bindiny mechanism can be made up of the screw thread and the sealing ring 9 that are provided with between box body 1 and the lid 2; Also can form by the elasticity card and the sealing ring 9 that are arranged between box body and the lid.Box body 1 is provided with handle 10.
