Abstract
A cup having an endless sidewall with a lower stacking shoulder formed of a sidewall and bottom heel including a convexly outwardly curved rib disposed at a transition between the sidewall and a cup bottom having a bottom wall having a recessed dome-shaped center section providing draw ratio bottom wall thickness reduction to an annular flat bottom wall section defining a puncture region of the cup. The cup sidewall has a ribbed section disposed adjacent the heel and extends upwardly at least one-quarter the height of the cup helping to strengthen the relatively thin sidewall to prevent it from undesirably deforming during puncturing of the cup bottom during beverage making. The cup may include an upper shoulder formed of an outwardly expanded section of the sidewall adjacent the top of the cup and defining an filter attachment seat on one side and a cup carrier on the opposite side.
