Abstract
A core for casting a container includes a casting surface, where the core is divided into at least two core segments. The casting surface of each core segment adjoins a division surface, and the division surface of each core segment is spaced apart from the division surface of a neighboring core segment by a gap. The gap is spanned by a frangible collapsible member such that substantially all of the casting surface is free of the collapsible member.
