<p>A unitary capseal (20) for a closure that is installed in a container includes an annular sidewall (40), a generally circular top panel (43)joined to the sidewall (40), a snap-on annular rim formed adjacent a lower edge of the sidewall, and an annular sealing lip formed adjacent the annular rim (42). The cooperating closure includes a serrated flange (22), a dosing plug (21) for threaded receipt by the flange (22), and a sealing gasket (24) positioned therewith. The container end is formed around the flange (22) interlocking with the flange serrations and creating an outer annular channel that receives the annular rim (42) for a snap-on assembly of the capseal (20) to the container end that in turn positions the capseal (20) over and around the closure. The sealing lip (45) extends radially outwardly from the sidewall (40) and includes a concave surface facing the container end for sealing off the interior portions of the closure from collecting debris.</p> |
