A method of making a press-on, twist-off container assembly, comprising steps of: (a) providing a container having a finish portion with at least one external thread defined thereon; (b) providing a press-on, twist-off type closure including a panel portion and a skirt portion that together define a generally cylindrical interior recess and a deformable gasket mounted within said interior recess that has a thread engaging portion having a plurality of inwardly extending raised flutes, said flutes being spaced circumferentially variably about said thread engaging portion; and (c) pressing the closure onto the container so that at least some of said flutes are in contact with at least one of said external threads at a first and a second contact point on said threads, each external thread having a total distance spanned by and between the first and second contact points, and wherein an aggregate distance spanned that is a sum of said total distance spanned for all of said external threads is less than an internal circumference of said thread engaging portion.
