Abstract: A method of making a preform assembly includes providing a preform having a closed end, and providing an attachment object having a ring. The attachment object is assembled to the preform by telescoping the ring over the closed end of the preform until the ring is brought into abutting engagement with a portion of the preform in such a way that interference between the ring and the portion of the preform prevents dislodgement or removal of the attachment object during subsequent processing of the preform assembly. The attachment object in the disclosed embodiments of the invention may be a handle, a label or a shroud. The ring on the attachment object may be circumferentially continuous or circumferentially split. Engagement between the attachment object ring and the preform may be by engagement with one or more external protrusions on the surface of the preform, or may be by interference press fit engagement between the ring and the external surface of the preform.

Abstract: A plastic container for holding aerosol contents under pressure includes a one-piece integrally molded plastic body having a base, a sidewall and a neck finish. The sidewall and the base are of oval cross-section, and the base has a contour and cross-section for maintaining the oval cross-section under aerosol pressure within the container body. The neck finish has an open mouth surrounded by a circumferentially continuous external bead for securing a dispensing closure. The bead has an undersurface that is perpendicular to an axis of the neck finish, and the neck finish has a chamferred inside edge around the open mouth to facilitate insertion of a dispensing closure.
