ABSTRACT:
A molded plastic closure for a beverage container, the closure having a shell with a top panel and a depending skirt, the shell being molded in one piece from a hard thermoplastic material. The closure is provided with an annular flange which extends from the underside of the top panel and which forms an annular space with the inside of the skirt. A liner is formed in situ within the closure by compression molding from a compression moldable soft, rubbery thermoplastic material, the underside of the top panel and the inside of the annular flange serving as molding surfaces. The annular flange is supported against lateral loads by a series of ribs which extend between the annular flange and the depending skirt. The liner is interlocked with the annular flange by interengaging ribs and recesses. Both a top seal only closure for non-pressurized beverages and a top and side seal closure for pressurized beverages are disclosed.
