Abstract:
A method of molding a container comprising the following steps:(1) injecting a fluid thermoplastic polymeric material into a container-molding cavity formed by and between first and second non-expandable cavity members, a core member that extends through said second cavity member into said first cavity member, and an end surface of a poppet member that extends through an axial hole in said core member, said container-molding cavity being shaped for molding a container having an open top end with a grooved rim;(2) after said injected material has solidified, separating said first cavity member from said second cavity member, said core member, and said end surface of said poppet member, with said plastic container remaining attached to said second cavity member, said core member and said end surface;(3) moving said core member away from said second cavity member in the direction of said first cavity member a distance sufficient to free said plastic container from said second cavity member, with said plastic container remaining supported by said core member; and(4) moving said poppet member relative to said core member so as to remove said plastic container from said core member.
