Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below. The structure, ratio, size and the like shown in the drawings of the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by people familiar with the technology, and are not used for limiting the limit conditions which can be implemented by the present invention, so that the present invention does not have the substantial significance in the technology, and any structure modification, ratio relationship change or size adjustment should still fall within the scope which can be covered by the technical content disclosed by the present invention without affecting the efficacy which can be produced by the present invention and the achievable purpose. In addition, the terms "upper", "lower", "left", "right" and "middle" used in the present specification are for clarity of description, and are not intended to limit the scope of the present invention, and the relative relationship between the terms and the terms is not to be construed as a scope of the present invention.

Referring to fig. 1 to 6, a thermal insulation lunch box with a double-layer structure comprises a box bottom 1, an inner container 2 and a box cover 3, wherein the inner container 2 is arranged in the box bottom 1 to form a box body, and a hollow thermal insulation cavity 11 is formed between the inner container 2 and the box bottom 1.

The upper end of the box bottom 1 is provided with a sealing edge structure 12. The inner side of the sealing edge formation 12 has a supporting edge 13. The supporting edge 13 is an arc-shaped structure which is bent inwards from top to bottom. When vertically piling up between a plurality of box bodys, support limit 13 plays the supporting role.

The cassette bottom 1 has a support structure located below the edge sealing structure 12. The support structure comprises a first connecting edge 14 and a second connecting edge 15. The first connecting edge 14 extends inwards along the horizontal direction, and the upper end of the inner container 2 is attached to the first connecting edge 14. The upper end of the inner container 2 is provided with an outer sealing edge 21 which extends outwards along the radial direction, and the front end of the outer sealing edge 21 is tightly attached to the first connecting edge 14 in a sealing way to seal the hollow heat preservation cavity 11. The inner bag 2 is placed in the box bottom 1, is pasted by outer banding 21 and is established on the right half of first flange 14, has formed holistic box body between inner bag 2 and the shell promptly, is the clearance setting between the lateral surface of inner bag 2 and the medial surface of the box bottom 1 to form cavity heat preservation chamber 11, connect the shaping back with inner bag 2 and box bottom 1, can pile up a plurality of box bodies and pack and transport.

An inclined step structure 17 is arranged below the second connecting edge 15, and a convex structure 22 is arranged at the lower end of the outer sealing edge 21. The inner container 2 is installed in the box bottom 1 so that the convex structure 22 contacts with the step structure 17 to support the inner container 2. For the stability of being connected between inner bag 2 and the box body, through step structure and protruding structure 22 cooperation, supported protruding structure 22 by step structure 17, realized the bearing to inner bag 2, avoided inner bag 2 to hold food back because the reason of food weight collapses downwards and lead to taking place to warp between inner bag 2 and the box bottom 1.

The hypotenuse that limit 15 is upwards setting is connected to the second, and limit 15 is the arc structure of from the bottom up lateral bending to the second. The cassettes are stacked with the supporting edge 13 of the lower cassette bottom 1 against the second connecting edge 15 of the upper cassette bottom 1. As shown in fig. 2 (two stacked cases are taken as an example in fig. 2), during the stacking process of the cases, one case is vertically installed in the other case and then clamped, after clamping, the lower part of the arc-shaped convex part of the first connecting edge 14 on the case bottom 1 at the upper end contacts with the convex part of the supporting edge 13 of the case body below, the outermost arc-shaped section of the second connecting edge 15 of the case bottom 1 at the upper end clings to the upper end of the supporting edge 13 of the case bottom 1 below, so that the case bottom 1 below supports the case bottom 1 above, and vertical support is realized, which can further reduce the space occupied by the stacked cases, and due to the supporting effect of the first connecting edge 14 and the supporting edge 13, the adjacent stacked cases still have a gap on the edge sealing structure 12, and can be conveniently separated from each other in use.

In the trade company's use, after the inside food that holds of box body, can realize food packing procedure with box body seal closure through lid 3. Establish lid 3 lid on the box body to be connected with banding structure 12, the outside limit is pressed to the lower terminal surface of lid 3, further compresses tightly through lid 3 between inner bag 2 and the box body this moment, and the clearance between the two is very little, prevents to pack the box and leads to the food in the inner bag 2 to flow into the box bottom 1 inside through the clearance between inner bag 2 and the box body because rock in the transportation.

The lower end of the box bottom 1 is uniformly provided with a plurality of grooves 16 at intervals along the circumferential direction, and the grooves 16 are obliquely and inwardly arranged along the vertical direction. The grooves 16 are of a wave-like structure. The rigidity of the box bottom 1 can be improved by the grooves 16 of the wave structures, meanwhile, the contact area of the box bottom 1 and a user is reduced, and the phenomenon that the hands of the user are scalded by high-temperature food in the inner container 2 is avoided.

Be different from prior art, the utility model discloses bilayer structure's heat preservation cutlery box can have the heat preservation function, can reduce the occupation space of the state of piling up, and the integrative scene of going out of box bottom and inner bag equipment is convenient for trade company's packing and is used.

The present invention and its embodiments have been described above schematically, and the description is not limited thereto, and what is shown in the drawings is only one of the embodiments of the present invention, and the actual structure is not limited thereto. Therefore, if the person skilled in the art receives the teaching of the present invention, without departing from the inventive spirit of the present invention, the person skilled in the art should also design the similar structural modes and embodiments without creativity to the technical solution, and all shall fall within the protection scope of the present invention.
