<p>A retortable plastic container (10) includes a main body (12) and a bottom (14). The bottom (14) defines a raised inner portion (20) and at least one substantially flat bottom support surface (22). The substantially flat bottom support surface (22) is curved and positioned near a radially outermost edge (23) of the bottom (14) when viewed in bottom plan. A groove (24) is defined in the substantially flat bottom support surface (22). In addition, a first side wall portion (40), that extends upwardly from the radially outermost edge (23) of the bottom (14) is shaped as a truncated cone, giving the bottom portion greater dimensional stability under retort conditions. The container bottom (14) exhibits superior dimensional stability with respect to predecessor designs.</p> |
