The lower part of the fastener is hooked with the box body, and the upper part of the fastener is connected to the box cover. When in use, the box cover can be separated from the box body by bending the lower part of the fastener outward to open the cover. Since the insulation box is used to keep food cold or hot, so that the food remains in its original state; the entire insulation box is very sealed when the cover is closed, and the chamber formed by the box body and the box cover is a vacuum chamber. In this way, when opening the cover, it is often difficult to open the box cover because the chamber of the insulation box is in a vacuum state. In order to facilitate the opening of the box cover, a vent valve is installed in the center area of ​​the box cover, so that after the buckle is opened, the vent valve can be operated to release the gas in the incubator, and the box cover can be easily opened upwards. However, the installation of the vent valve requires the operator to operate in two steps when opening the cover, and on the other hand, most of the vent valves are rotary and are installed on the outer surface of the center of the box cover, which is very easy to be misoperated by others, especially children, resulting in the insulation effect of the incubator being affected.
