Abstract
The utility model provides a combined type heat insulating lunch box. The combined type heat insulating lunch box comprises at least two layers of stackable box bodies, wherein each box body comprises an outer sleeve, an inner container, and a vacuum interlayer formed by the outer sleeve and the inner container; the uppermost layer of box body is provided with a sealing cover for preserving heat and preventing food leakage; a first sealing cover for preserving the heat and preventing the food leakage is arranged between two adjacent layers of box bodies. Due to the arrangement of at least two layers of stackable box bodies, different types of foods such as vegetables, rice and soup can be contained separately when people are in outdoor places, and the box bodies can be randomly stacked so as to provide convenience for use of people. In addition, the vacuum interlayer is used for heat insulation, a good heat insulation effect is achieved, and the heat insulation duration time is long; due to the arrangement of the sealing cover and the first sealing cover, the airtightness of a joint between the adjacent stacked box bodies is guaranteed, the heat insulation performance of the heat insulating lunch box is improved, the leakage of the foods in the box bodies is prevented as well, and the heat insulating lunch box is convenient for people to use.
Description
Technical field
The utility model relates to a kind of Combined thermal insulation lunch box, belongs to daily living article field.
Background technology
Go out work, to go to school for each family be inevitable thing, increasing people is with respect to the health of having a meal and nutrition, thereby makes portable lunch box become gradually the necessity in family life.Traditional lunch box is the container of being made by single-layer metal or plastic material, and lid is set on container, although this kind of lunch box is light, heat insulation effect is poor.
For addressing the above problem, prior art discloses a kind of incubation canteen as Chinese patent CN22663552Y, and described incubation canteen comprises a box body that consists of vacuum interlayer inner bag and overcoat, and the shape of box body can be geometry arbitrarily; The air exhaust nozzle 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 on described lid on box body; The inner rim of lid is provided with double-layer seal cushion rubber.Box body adopts particularly stainless steel materials making of metal material, and the lower surface of lid can be inlayed stainless steel materials, so that the food in box body does not contact with plastics.The lunch box of the prior art, the vacuum interlayer consisting of double-layer metal material (double-layer stainless steel sheet material) is realized insulation, high insulating effect, the insulation duration is long.But the incubation canteen of the prior art only has the space of a packing foods, the different classes of food such as meal, dish, soup separately can not be held, inconvenient people use.
The problem that can not separately hold in order to solve meal, dish, soup etc., prior art is a kind of portable combined boxed cassette as Chinese patent CN202800455U discloses, comprise box body and cover the lid on box body, described box body is one or one and mutually splices above, and outside and inside, lower end, the upper end of box body is provided with screw thread, box body is screwed and is spliced by screw thread, good airproof performance, and box body can independent assortment, thus dish, meal, soup separately can be held, not taint of odour each other, mouthfeel is good.Box body is double-decker, and internal layer is ceramic bowl, plays insulation effect.Described lid edge is provided with two foldable handles, guides and supports conveniently.But the incubation canteen of the prior art, internal layer is ceramic bowl, because ceramic bowl can not be made hollow or interlayer, can only lean on the thickness of self and the characteristic of poor thermal conductivity to play certain insulation effect, but utilize ceramic bowl respond well in the insulation short time, after long-time, effect is general, for going to work/go to school morning, carries the working clan/student of lunch, can not meet their demand.
To sum up, lack a kind of high insulating effect, insulation duration long in prior art, and the lunch box that the different classes of food such as meal, dish, soup separately can be held is for people to use, and this kind of demand is along with the quickening of modern life rhythm becomes day by day urgent.
