The container mainly comprises a cylindrical container body with an opening at the upper part, a box cover capable of being hermetically covered on the container body, and a cover containing disc capable of being erected on the container body, wherein the container body and the box cover are respectively of a double-layer wall structure with gaps in the middle. Can prevent the temperature of the stored food from easily losing, and achieves the effect of heat preservation.
Description
Technical field
The utility model relates to a kind of apparatus of filling a bowl with rice, especially incubation canteen.
Background technology
The work owing to go out, to go to school be the inevitable thing of each family, and be misgivings household's nutrition health, the use of lunch box more becomes essential articles for use, no matter and general lunch box single or multiple lift formula, it all is single-layer type wall structure, its heat insulating ability is relatively poor, is difficult for keeping for a long time the temperature of food in the box, influences eating mouth feel and easy gastrointestinal disease etc.
Summary of the invention
The purpose of this utility model is to provide a kind of incubation canteen, and the food that this lunch box has storing gives heat insulation function, thereby reaches the purpose that can take the storage insulation for a long time.
Above-mentioned purpose of the present utility model is to realize by such technical scheme: promptly the utility model comprises the cylinder-shaped vessel of a top opening, but the lid of a closed cover on vessel, one can be placed on the Sheng shrouding disc on the vessel, leaves the two-layer equation wall structure in gap in the middle of described vessel and lid are respectively.
The described two-layer equation wall gap shape that is evacuated.
Described lid and vessel can by screw togather, the buckle mode is mutually airtight.
The utility model compared with prior art has following advantage after adopting technique scheme: prevent to store food temperature and be easy to run off, reach heat preservation effect.
Description of drawings
Figure one is the stereogram of the utility model embodiment.
The specific embodiment
Below in conjunction with embodiment the utility model is further described.
The utility model mainly is by being to be combined by vessel (1) and lid institutes such as (2): wherein vessel (1) is the cylinder-shaped storage box body of top tool opening (10), and lid (2) is the lid that can cover closed container body (1) top opening (10), vessel (1) and lid (2) are to manufacture respectively to form the middle double-deck wall structure that leaves gap (3), and in gap (3), can form vacuum or betwixt the filling heat-barrier material (as air, Poly Foam, insulation liquid etc.), via screwing togather, modes such as buckle make vessel (1) and lid (2) fixed mutually, also can between vessel (1) and lid (2), add in addition to put and contain shrouding disc (4), for the different foods of holding.
When using, the user can be with the food device of want splendid attire at vessel (1) and contain in the shrouding disc (4), to contain shrouding disc (4) adds and puts on vessel (1), then lid (2) by the top screw lock on vessel (1), give top opening (10) airtight, because vessel (1) and lid (2) are the double wall surface constructions, winding covers back integral body and also becomes two-layer equation wall holding box body, make the splendid attire food in the vessel (1), delay to intercept the temperature conduction effect because of what be subjected to gap (3) and inner thermal insulator thereof, and the food temperature that can avoid storing in the lunch box is easy to run off, and reaches the effect of taking the storage insulation for a long time.
Claims (3)
1, a kind of incubation canteen, the cylinder-shaped vessel that comprises a top opening, but the lid of a closed cover on vessel, one can be placed on the Sheng shrouding disc on the vessel, it is characterized in that described vessel and lid are respectively the middle two-layer equation wall structure that leaves the gap.
2, a kind of incubation canteen according to claim 1 is characterized in that the described two-layer equation wall gap shape that is evacuated.
