P.P. Cap is an acronym for "Pilfer Proof," meaning "theft-proof”. When the bottle is opened, a bridge at the bottom of the cap breaks off, indicating that the bottle has been temporarily opened. The cap is also called a roll-on cap because the threads of the cap are formed by a sealing machine after it is placed over the glass bottle.
