Description
The utility model relates to a kind of lunch box, particularly a kind of lunch box with vacuum heat-preserving performance.
Sale and the widely used lunch box of user are broadly divided into three classes in the market: plastic product, aluminum products, stainless steel products.These lunch boxes which kind of all have its intrinsic shortcoming.The first is used for splendid attire heat when using thing scalds one's hand easily, uses inconvenience, and it two is because structure and materials used are limit, the heat transfer rapid heat dissipation, and heat-insulating property is poor.
The purpose of this utility model provides a kind of incubation canteen with fabulous heat-insulating property.
The purpose of this utility model is achieved by the following technical solution:
Incubation canteen described in the utility model is made up of three parts such as box body, middle cover, loam cakes, is characterized in: box body adopts double-decker, and the interlayer folder vacuumizes in the chamber, and at the box body inner chamber dividing plate is set the box body inner chamber is divided into some storerooms; The double-deck middle cover that vacuumizes in being provided with above storeroom is provided with strip of paper used for sealing between middle cover and the dividing plate; Be provided with loam cake above middle cover, this loam cake and box body are openable flexible connection.
The utility model has the advantages that: the box body middle cover is a double-decker, vacuumize in the layer, owing to be provided with heat-conduction medium in the layer, thus cut off the inside and outside heat conduction path of box more effectively.So the heat-insulating property of box body is fine, be convenient in the winter time or cold district is used to carry or deposits heat-producing food, make it that long temperature retention time be arranged.Be applicable to field work, the usefulness that go out outing or long period are preserved the food of heat.And box body inner chamber of the present utility model is provided with dividing plate, can be used for depositing respectively meal, dish, soup class or different types of food, avoids food to mix, taint of odour mutually.
Below in conjunction with an embodiment the technical solution of the utility model is described further:
What Fig. 1 bore is agent structure axle cutaway view;
