Abstract
A unitary capseal for a closure that is installed in a container includes an annular sidewall, a generally circular top panel joined to the sidewall, a snap-on annular rim formed adjacent a lower edge of the sidewall, and an annular sealing lip formed adjacent the annular rim. The cooperating closure includes a serrated flange, a closing plug for threaded receipt by the flange, and a sealing gasket positioned therewith. The container end is formed around the flange interlocking with the flange serrations and creating an outer annular channel that receives the annular rim for a snap-on assembly of the capseal to the container end that in turn positions the capseal over and around the closure. The sealing lip extends radially outwardly from the sidewall and includes a concave surface facing the container end for sealing off the interior portions of the closure from collecting debris.
