ABSTRACT A preformed plastic structure for making open-mouth plastic containers is disclosed. The structure is an oriented preform having a base defined by an inner circular portion and an outer circular portion situated parallel to the outer circular portion and spaced therefrom. The radius of the outer circular portion is larger than the radius of the inner circular portion. The preform is further provided with an outwardly extending annular member integral with the base and tapering therefrom, the member forming an angle of between about 2° to about 30° from the base, and a flange integral with the annular member and extending radially outwardly and having a cross-section configuration of substantially the rim of the finished container. The preform is well suited for forming multilayered containers.
