Abstract

The utility model discloses a thermal insulation lunch box which belongs to a thermal insulation container, comprising a box body whose vacuum sandwich layer is composed of an inner liner and an outer sleeve, wherein, the shape of the box body can be any geometric shapes, a sucking gas nozzle of the vacuum sandwich layer is arranged on the side surface of the box body, the upper part of the box body is provided with a cover, the cover can be fixed to the box body by a clamp, and the inner periphery of the cover is provided with double layers of rubber sealing rings. The thermal insulation lunch box can be used for containing solid or liquid food. A temperature is unlimited. The thermal insulation and the sealing effects are good. The thermal insulation lunch box is nontoxic. When the thermal insulation lunch box is made, the thermal insulation lunch box can be made into various geometric shapes as required. The thermal insulation lunch box has the advantages of beautiful appearance, convenient carrying, and convenient operation.

Description

Incubation canteen

The utility model belongs to a kind of cool-bag.

Before the utility model was realized, people were generally used for carrying the container of apparatus for making with layer of metal or plastic material of food, though this container is light, heat insulation effect is poor, and harmful.Sometimes people make food keep certain temperature (cold or hot), and often adopting inner bag is that the vacuum flask of glassware carries food, very inconvenient but above-mentioned vacuum flask carried when using, and has vibration very easily broken slightly, uses dangerous.

The purpose of this utility model provides a kind of fort temperature lunch box, thereby has solved the problem that exists in the above-mentioned prior art.

Basic fundamental solution of the present utility model is: described incubation canteen comprises that one constitutes the box body of vacuum interlayer by inner bag and overcoat, and the shape of box body can be geometry arbitrarily; The mouth of bleeding of vacuum interlayer is arranged on the side of box body, and lid is arranged at the top of box body, and available folder is fixed in described lid on the box body; The inner rim of lid is provided with the double-layer seal cushion rubber.

Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated:

Accompanying drawing is the structural representation of the utility model embodiment.

In the accompanying drawing, the face shaping of box body is cylindric, and with metal material particularly stainless steel materials be that material is made.Box body is by inner bag (1), and overcoat (2) constitutes, the two in the upper edge of box body with the wedge angle welded seal.The lower surface of inner bag is circular-arc, can copper facing on the inner surface of interlayer or coat one deck aluminium foil, and to improve heat insulating effect.On the close position of upper edge of inner bag, inside newborn protruding (23) of a week are arranged.When the volume of box body is big, can also be provided with on inner bag that one or several is inside newborn protruding, and one or several taper back-up block correspondingly is set between inner bag and overcoat, be supported between inner bag and the overcoat.

Mouth of bleeding (3) to evagination and sealing is arranged in the side of described overcoat, during fabrication, by the metal tube at this mouth place of bleeding, the state that is evacuated in the interlayer with inner bag and overcoat formation, sealed metal tube can form the shape as figure then.This mouth of bleeding is arranged at the side of box body, can reduces the thickness of box body interlayer, reduce the annex of product, make product exquisite, practical more, and can reduce cost.In the outside of bleeding mouth, can weld a stator (19), fixedly to mould a part (4).This is moulded and reaches the drop handle (21) that is connected with hand body band connector fixing a hand-strap connector (22) by fixture (17), (18) on the part, so that carry, also this can be moulded part is designed to the end handle, so that use, thereby reach use, easy to carry, effect attractive in appearance.Inboard below overcoat can also be provided with an air-breathing bowl (15), and interior dress inspiration piece (16) is in order to keep the vacuum in the interlayer.In the outer upper of described overcoat, folder (8), (9) that several connect with the stator (14) of welding can be set, in order to fixed cap, also can after opening, be used as the end handle.A trade mark card (13) can be set on the described folder.

Described lid is by the loam cake of geometry (11) as shown in the figure, enclosing cover (12), and inner cap (7), and the foam core (10) that is sandwiched between enclosing cover and the inner cap constitutes.Loam cake is with metal material, preferably stainless steel materials manufacturing, and enclosing cover and inner cap are all injection molded.The lower surface of inner cap can be inlayed stainless steel materials (20), so that the food in the box does not contact with plastics.The side of described inner cap is stairstepping, the tight fit that outermost end can be slided is embedded in the periphery inboard of enclosing cover, on the circumference at side ladder place, be provided with a cushion rubber (5), (6) respectively, so that when closing the lid, cushion rubber (5) is corresponding to the upper edge of box body, cushion rubber (6) newborn protruding corresponding on the inner bag, thus can reach the effect of double-layer seal.

During use, in the box body of food can being packed into, after closing the lid, lid is fixed on the box body, promptly can reaches the sealing heat preservation effect with folder.This practical parental type can be used to hold the food of solid or liquid, and temperature is unrestricted, and insulation and good sealing effect are nontoxic.During making, can make various geometries as required, good looking appearance carries, easy to use.
