Abstract
A container includes a neck finish extending from a body and having at least two thickened wall portions circumferentially spaced apart and extending radially inwardly, and including interior surfaces disposed radially inwardly of a neck finish interior surface to at least partially establish an internal trough, and axially facing shoulders axially recessed with respect to a sealing lip of the neck finish.
Claims20
A method of making a container that includes the steps of:
- forming a parison in a blank mold wherein the parison includes a body and a neck finish, and the neck finish includes a neck finish interior, a sealing surface facing generally axially and extending fully circumferentially continuously around the neck finish interior, and at least one axially facing shoulder, wherein the forming step comprises:
- forming, by a plunger of the blank mold, a first portion of the neck finish interior to have a first geometry with at least two thickened wall portions circumferentially spaced apart, and extending radially inwardly and chordally with respect to the neck finish, wherein the thickened wall portions included interior surfaces to at least partially establish an internal trough, the plunger having a non-circular cross-section to form the first portion of the neck finish interior with a corresponding non-circular cross-section;
- and
- forming, by one of the plunger and a guide ring of the blank mold, a second portion of the neck finish interior to have a second geometry different than the first geometry and that includes the at least one axially facing shoulder being axially recessed with respect to the axially facing sealing surface;
- and
- blowing the parison in a blow mold to form the container, which has the neck finish having the axially facing sealing surface extending fully circumferentially around the neck finish interior and the neck finish interior having the at least one axially facing shoulder axially recessed with respect to the axially facing sealing surface.
