Abstract
The invention relates to a multi-layered composite heat-preserving lunch box which consists of a heat-preserving cover and a heat-preserving chamber, wherein the heat-preserving cover and the heat-preserving chamber are compounded by outer layers and heat-preserving materials wrapped by the outer layers. The heat-preserving cover consists of the outer layer, the heat-preserving material, a connector and an upper seal gasket, and the heat-preserving chamber consists of the outer layer, the heat-preserving material, an opening and a lower seal gasket. The lunch box has the characteristics of good sealing performance, high heat-preserving degree and long heat-preserving time, and brings convenience to life, work and travel of people.
Description
Technical field
The present invention relates to a kind of incubation canteen, especially a kind of multilayer composite heat insulating lunch box with heat preservation property that has used multilayer material to make, belongs to daily necessities field.
Technical background
Lunch box is one of article conventional in life, particularly travel outdoors, life, work, the chance of using during study is more, our common lunch box great majority were individual layers in the past, or double-deck, as stainless steel lunch box, plastic lunch box, aluminum products lunch box, or there is heat-preserving container of glass inner bag etc., these lunch boxes or heat-preserving container are owing to being subject to the impact of self structure, cause them to exist heat insulation effect not ideal enough, the unfavorable factors such as temperature retention time is short, to people, bring inconvenience, therefore, people need a kind of new incubation canteen to produce as early as possible, to solve existing problem or defect, object of the present invention is exactly in order to solve current existing problem, and the new technical scheme with substantive progress and feature proposing.
Summary of the invention
In order to reach the object that solves above-mentioned existing problem, the technical scheme that the present invention proposes is a kind of multilayer composite heat insulating lunch box, it is characterized in that: it consists of insulation cover, heat-insulated cavity; Insulation cover and heat-insulated cavity are to be all composited by multilayer material, insulation cover consists of skin, insulation material, jockey, upper sealing gasket, heat-insulated cavity consists of skin, insulation material, opening, lower seal pad, and the jockey on insulation cover can correspondingly with the opening on heat-insulated cavity coincide.
The technical characterictic that the present invention program also has is: insulation cover and heat-insulated cavity are all by outer and centre, to have been wrapped up that insulation material is compound to be formed.
The technical characterictic that the present invention program also has is: upper sealing gasket is arranged at the below of insulation cover, and lower seal pad is arranged at the top of heat-insulated cavity, and upper sealing gasket can be connected with lower seal pad.
Summary of the invention
The advantage that the present invention compared with prior art had and significant progressive:
1, good seal, insulation degree is high.
2, temperature retention time is long.
Below in conjunction with accompanying drawing, the present invention will be described in detail
Fig. 1 is the embodiment overall schematic of a kind of multilayer composite heat insulating lunch box of the present invention.
In figure, 1 insulation cover, 2 skins, sealing gasket on 3 insulation materials, 4,5 jockeys, 6 heat-insulated cavities, 7 openings, 8 lower seal pads.
The specific embodiment
Referring to Fig. 1, in embodiment, in insulation cover 1, outer 2 are wrapped in insulation material 3, are provided with jockey 5 and upper sealing gasket 4 below insulation cover 2, are provided with opening 7, lower seal pad 8 on heat-insulated cavity 6, in heat-insulated cavity 6, outer 2 are wrapped in insulation material 3, by corresponding opening 7 combinations of the jockey on insulation cover 15, just form complete insulation multilayer composite heat insulating lunch box.
Adopt a kind of multilayer composite heat insulating lunch box of the present invention program, not only heat-insulating property is high, portable, but also can be for the needs of other side.
Certainly; by above-mentioned for example and explanation a kind of multilayer composite heat insulating lunch box of the present invention is disclosed; some technical characterictics and scheme; it also has other advantages and feature; the technical program is not limited to above-mentioned giving an example and explanation; those of ordinary skill involved in the present invention, some that in the essential scope of the technical program, it is done changes as adds, accepts or rejects or replace, within also should falling into protection scope of the present invention.
