Abstract
The present invention provides a membrane-type vented food box, including a bottom wall, side walls, an accommodating space and opening on top of the side wall. A membrane is adhered onto the joint surface of the opening, and air vents are opened on at least two opposite sides of the side wall of the box. The spacing between the bottom of air vents and the bottom wall must be bigger than 1 cm, and air flows transversely across the food box, so the superimposed food box may not affect air ventilation, thus providing an optimum air ventilation effect. Thanks to a spacing bigger than 1 cm between the bottom of air vent and the bottom wall, the steam generated by food in the accommodating space can be easily discharged, thus providing a better preservative effect with improved applicability.
