Abstract
The utility model relates to a kind of food cool-bag, is specifically related to a kind of heat preserving antistaling box.It comprises box body and lid, it is characterized in that: described box body and lid are all double-deckers, in described box body, is also provided with one deck inner box layer, is also provided with box body thermal insulation layer between inner box layer and box body; Cover plate above being provided with on described lid, lid and above be also provided with lid thermal insulation layer between cover plate; Lid is provided with the groove coordinating with ora terminalis on inner box layer, is provided with seal ring in groove.The utility model structure design advantages of simple, is set to double-decker by heat preserving antistaling box, and adds thermal insulation layer between bilayer, can effectively reduce like this thermal exchange in box and outside box, keeps the temperature in lunch box; Junction at lid and box body arranges seal ring, can make heat preserving antistaling box better seal, and further ensures the temperature in heat preserving antistaling box, and it is fresher that good sealing can make to be contained in heat preserving antistaling box, is difficult for corrupt.
Description
Technical field
The utility model relates to a kind of food cool-bag, is specifically related to a kind of heat preserving antistaling box.
Background technology
Current incubation chamber on the market, what generally all adopt is single layer structure, the material of the inside is directly with the contact of box body, no matter be that cold or hot material puts in, owing to there is no the heat insulation of heat-insulation layer, the material of the inside is few with the heal differential of outside soon, so not enough to some extent for the insulation of going out to carry and preservativity.
Utility model content
Object of the present utility model is to provide a kind of good seal performance, effectively the plastic, thermal-insulation crisper of heat preserving antistaling.
The utility model object is achieved in that
A kind of heat preserving antistaling box, comprises box body and lid, and described box body and lid are all double-deckers, in described box body, are also provided with one deck inner box layer, are also provided with box body thermal insulation layer between inner box layer and box body; Cover plate above being provided with on described lid, lid and above be also provided with lid thermal insulation layer between cover plate; Lid is provided with the groove coordinating with ora terminalis on inner box, is provided with seal ring in groove, can keep the temperature in lunch box by actv. like this.
Technique scheme also can be made to the following further improve.
Described box body thermal insulation layer and lid thermal insulation layer are all low heat conductivity thermal insulation material, are also provided with one deck reflective aluminium foil on low heat conductivity thermal insulation material surface; In double-decker, fill low heat conductivity thermal insulation material and reduce hollow layer air heat convection conduction, can effectively reduce heat runs off, and be covered with again one deck reflective aluminium foil on the thermal insulation material of filling, further the infrared radiation reflection producing in box is returned in box, reduce greatly heat and run off, can keep the slow variation of temperature within a period of time in box.
Described lid is provided with clasp, and box is held with it and is formed with the flange coordinating with clasp.The flange of inner box layer upper end coordinates with the clasp on lid, and heat preserving antistaling box is sealed.
Described double-decker, employing be welding manner sealing, further prevent that in hollow layer, air exchanges loses heat with extraneous air.
The utility model structure design advantages of simple, is set to double-decker by heat preserving antistaling box, and adds thermal insulation layer between bilayer, can effectively reduce like this thermal exchange in box and outside box, keeps the temperature in lunch box; Junction at lid and box body arranges seal ring, can make heat preserving antistaling box better seal, and further ensures the temperature in heat preserving antistaling box, and it is fresher that good sealing can make to be contained in heat preserving antistaling box, is difficult for corrupt.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further described:
Structure of the present invention as shown in Figure 1, a kind of heat preserving antistaling box, comprise box body 6 and lid 3, box body 6 and lid 3 are all double-deckers, in described box body 6, be also provided with one deck inner box layer 4, what box body 6 and inner box layer 4 adopted is welding manner sealing, is also provided with box body thermal insulation layer 5 between inner box layer 4 and box body 6; Cover plate 1 above being provided with on described lid 3, lid 3 is same with upper cover 1, and what adopt is welding manner sealing, lid 3 and above be provided with lid thermal insulation layer 2 between cover plate 1, described box body thermal insulation layer 5 and lid thermal insulation layer 2 are for being all low heat conductivity thermal insulation material, also be provided with one deck reflective aluminium foil 18 on low heat conductivity thermal insulation material surface, can keep the temperature in lunch box by actv. like this; Described lid 3 is provided with the groove 12 coordinating with ora terminalis on inner box layer 4, is provided with seal ring 11 in groove 12; Lid 3 is provided with clasp 21, and inner box layer 4 upper end are formed with the flange 22 coordinating with clasp 21; The flange 22 of inner box layer 4 upper end coordinates with the clasp 21 on lid 3, and heat preserving antistaling box is sealed.
