A simple apparatus for forming a fill line in a paper beverage container such as a paper cup is disclosed. The apparatus includes no moving parts. A fill line is formed by forcing a punch of a mating ring into a finished cup positioned in a die which includes an annular recess spaced below the rim of the finished cup, the annular recess terminating in a bottom edge which serves as an anvil surface for forming the fill line. The fill line provides a user of the beverage container with a reference point for establishing a consistent measure of volume. The advantage is a simple apparatus adapted to be fitted to most paper cup finishing machines. The apparatus has no moving parts and is therefore not prone to requiring maintenance or replacement.

An apparatus for forming a fill line in a sidewall of a paper cup comprising: a die for supporting a sidewall of the paper cup, the die including a top edge for supporting a rim of the cup and an annular recess located beneath the top edge, the annular recess having a bottom edge spaced beneath the rim; a mating ring which includes a punch that is adapted to be received within the cup without distorting the rim, the punch being disc shaped and including a protruding annular shoulder located at a bottom edge thereof, a bottom surface of the annular shoulder contacting the bottom edge of the annular recess to form the fill line; whereby when the punch is forced downwardly within a cup positioned in the die, the punch stretches the sidewall of the cup into the recess and an annular ridge is formed in the sidewall when the mating ring abuts the bottom edge of the annular recess, the annular ridge providing the fill line as a reference point for establishing a consistent measure of volume.
