Description

Insulation environmental protection lunch box

The present invention relates to a lunch box, especially a heat preservation and environmental protection lunch box.

With the rise of delivery platforms, competition in the catering market has become more intense. Among them, disposable lunch boxes need to be used for delivery, and the material of the lunch boxes is nothing more than cardboard boxes (or plant fiberboard boxes) or plastic boxes. However, the use of plastic boxes has been gradually banned in some countries. Regulated use.

However, neither the cardboard box nor the plastic box itself has the function of heat preservation. Therefore, in the current delivery, only a simple container can be used to place all the food boxes that are delivered and keep them warm. The effect of heat preservation is quite limited, so it is easy to cause the food to deteriorate, affect the taste, and even cause the food to spoil. Especially in cold seasons or regions, it is easier to accelerate the speed of food spoilage. I really have to pay attention to it and improve it. The demand.

Although in some take-out food occasions, consumers can bring their own stainless steel vacuum insulated lunch boxes to overcome the problem of heat preservation, but the stainless steel vacuum insulated lunch boxes are expensive, inconvenient to use, and are delivered to the home. Nor can it be applied.

In order to solve the above-mentioned problems, the present invention discloses a thermal insulation and environmentally friendly lunch box. An inner box is installed between the box body and the upper cover. According to this, the lunch box has the effect of heat preservation.

In order to achieve the above objective, an embodiment of the present invention provides a heat preservation environmentally friendly lunch box, which includes a box body, an inner box and an upper cover.
