- and
- (b) a side wall comprising:
- (i) a first side wall portion of a first length extending upwardly and radially outwardly from the radial edge of the bottom at a first constant angle such that a lower end of the first side wall portion adjacent the bottom has a smaller diameter than an upper end of the first portion;
- (ii) a shoulder extending radially outwardly from the upper end of the first side wall portion such that a lower end of the shoulder adjacent to the upper end of the first side wall portion has a smaller diameter than an upper end of the shoulder;
- and
