Resealable container and closure package

摘要

A resealable container and closure package includes a container and a closure cap. The container has a longitudinal center axis, and a finish. The finish includes an external thread, an annular lip, and a sealing surface. The external thread includes 1.5 turns of a complete thread having symmetrical flank angles of about 13 degrees. The lip extends radially inwardly from a neck at an angle from about 0 degrees to about 5 degrees from a plane orthogonal to the center axis. The sealing surface is on an exterior surface of the lip. The closure cap includes an end wall defining a circumferential edge, an annular skirt projecting from the end wall, and an internal thread defined on an inner surface of the annular skirt. The internal thread is threadingly engageable with the external thread. The internal thread has an “M” style cross section for an SP 400 Finish.
