Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Example 1

As shown in fig. 1 to 3, the present embodiment provides a double-deck thermal container comprising a container body having an inner storage space for accommodating food and an opening for allowing food to enter and exit, and a cover 1 capable of covering the opening; the box body comprises an outer layer 2 and an inner layer 3, wherein the inner layer 3 directly forms an internal storage space, and the inner layer and the outer layer are of a seamless fixed connection integrated structure.

The bilayer structure of inlayer 3 and skin 2 makes the insulation can both have the light characteristics that outer 2 insulation material keeps warm, has the convenient clean, clean sanitary characteristics of inlayer 3 again, simultaneously because two-layer be seamless fixed connection structure, the insulation can washs conveniently, during water can not permeate into gap between them, can avoid liquid to remain for a long time and breed the bacterium.

The outer layer 2 is made of a heat-insulating material, such as a safe foam material, in the embodiment, an EPP heat-insulating material is selected, the EPP is an abbreviation of foamed polypropylene, Expanded polypropylene is a high-crystalline polymer/gas composite material with excellent performance, and the EPP is a novel compression-resistant buffering heat-insulating environment-friendly material, can be recycled, can be naturally degraded and cannot cause white pollution.

The inner layer 3 is made of a waterproof, impermeable food grade material, such as a safe metal material like aluminum, stainless steel, or a high strength glass material or plastic. In the present embodiment, the inner layer 3 is made of a stainless material.

In order to improve the tightness of the connection structure of the stainless steel inner layer 3 and the stainless steel outer layer 3, the stainless steel inner layer 3 is placed in a foaming mould, and the EPP heat-insulating material is directly foamed and shaped integrally outside the stainless steel inner layer 3, so that the inner layer and the outer side of the box body form an integral structure.

In order to improve the firmness and cleanness of the opening position of the box body, a boss structure 31 is arranged at the position of the opening close to the internal storage space, and the stainless steel inner layer 3 extends to the outside of the box body from the internal storage space and wraps the boss structure 31. The boss structure 31 at the opening is wrapped by the stainless steel turnover part, so that the two connecting ports are more tightly and firmly connected, and the layering is less likely to occur. And when directly holding liquid food, can directly outwards pour out food along the opening, liquid food also can flow out along the stainless steel boss, avoids contacting outer 2 heat preservation.

The box cover 1 can be covered on the boss structure 31, the firmness and tightness of the cover of the box cover 1 and the box body are increased, and the heat insulation effect of the heat insulation box is improved.

The double-deck insulation can of this embodiment still includes the inner cup 4 of making by the stainless steel, earlier with 4 locks of inner cup on the opening, then closes case lid 1 again, because inner cup 4 is stainless steel material, the contact surface of food is stainless steel material, has fully guaranteed the security of food, also can avoid case lid 1 to be polluted by food simultaneously.

In this embodiment, the middle part of the inner cover 4 is provided with a hemispherical concave limiting structure, and a worker places a hand in the concave limiting structure and pushes against the inner wall of the concave limiting structure to the outside, so that the inner cover 4 can be lifted.

In order to facilitate carrying the double-deck thermal insulation box of the embodiment, the outer portion of the box body is provided with a handheld portion 21, and in order not to affect the stacking and storage of the box body, the handheld portion 21 is a groove structure arranged on the side surface of the box body.

In order to open the case cover 1 conveniently, the edges of the case body and the case cover 1 are provided with slot structures 22 which facilitate opening the case cover 1, specifically, the slot structures 22 of the embodiment are notch structures which are arranged at four corners of the top surface of the case body and at the edge positions of the side walls, when the case cover 1 is covered on the case body, the notch structures form slots which allow fingers to be inserted, and the case cover 1 can be opened conveniently.

Example 2

In order to conveniently sort and contain food, the internal storage space of the box body can be separated into independent spaces with different quantities through the partition plates 5, the partition plates 5 can also play a role in supporting food, and the partition plates 5 can be fixedly connected with the inner layer 3 and can also be detachably connected through the slot structures 22.

As shown in fig. 4, the present embodiment sets the internal storage space of the inner layer 3 to 3 independent spaces by providing two partition plates 5.

Example 3

As shown in fig. 5, the present embodiment is different from embodiment 2 in that the inner layer 3 is provided with a partition 5 to divide the internal storage space of the inner layer 3 into two independent spaces.

The above embodiments are only specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of changes or substitutions within the technical scope of the present invention, and all should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
