Ultrathin hermetic anti-theft fast food box

The invention belongs to the technical field of fast food boxes and relates to an ultrathin hermetic anti-theft fast food box. The ultrathin hermetic anti-theft fast food box comprises a box body and a box cover. A first buckling portion is annularly arranged at the lower edge of the box cover; a second buckling portion is annularly arranged at the upper edge of the box body, the first buckling portion and the second buckling portion can be hermetically buckled; at least one part of the second buckling portion of the box body is an easily broken part which is structured such that fragments of the buckling portion are integrally formed at the notch of the box body on the outer wall through easily broken thin sheets which are arranged in a spaced manner to form the easily broken part, and more than one strip-like hole is formed between the box body and the easily broken part of the box body through the thin sheets. The fast food box has the advantages that the fast food box is simple in structure; whether the box is opened or not can be judged by judging whether the easily broken part is matched or not to remind the diner to judge whether foods in the fast food box are short or are polluted or not; as the strip-holes and openings are formed, the anti-theft function is increased on the premise of not increasing the production cost, or even reducing the production cost, the product grade is high, and the fast food box is suitable for being popularized and applied in fast food industry.
