1. An anti-theft plastic bottle cap comprising;
a body configured to be connected on an opening of a bottle;
an anti-theft ring mounted on a bottom of the body; and
multiple equidistant connection teeth between the body and the anti-theft ring,
wherein the body includes a first protrusion extending to the anti-theft ring from the bottom of the body, and the anti-theft ring includes two second protrusions extending to the body,
wherein the multiple equidistant connection teeth each extend from a top surface of the two second protrusions,
wherein when the body is rotated counterclockwise, the multiple equidistant connection teeth are removed, allowing a user to determine that the bottle has been opened, and,
wherein when the body is rotated clockwise, the first protrusion engages with the two second protrusions, such that the anti-theft plastic bottle cap is not rotated overly by using the first protrusion and the two second protrusions to avoid a removal of the anti-theft ring from the body and the anti-theft ring before the user detaches the anti-theft plastic bottle cap from the bottle.
