A plastic container includes a neck with an opening to an interior of the container, where the neck opening having a first diameter and a second diameter of different lengths. A shoulder portion surrounds the neck of the plastic container. A transfer bead is located on the neck above the shoulder portion where the first diameter of the neck opening is above the transfer bead and the second diameter is below the transfer bead. The transfer bead is advantageously shaped and sized so as to facilitate application and removal of a sterilization solution during the aseptic packaging process.

A plastic container includes a neck with an opening, a bell portion surrounding the neck, a body portion including at least one 'm'-shaped horizontal rib, and a base where the body portion is located between the bell portion and the base.

Aseptic structural rib for plastic containers

A squeezable tube-shaped plastic container ( ) having a one-piece construction formed by extrusion blow-molding techniques. The container ( ) has a retractable end wall ( ) which is positionable into an outwardly projecting position and an inverted position. The end wall ( ), as blown, is in the outwardly projecting position and is thereafter inverted so that a tamper indicating covering ( ) can be attached to the end ( ) of the container ( ) thereby sealing the end wall ( ). The inverted end wall ( ) permits the container ( ) to be free standing on the standing ring ( ). In use, the flexible sidewall ( ) of the container ( ) is squeezed to snap the end wall ( ) from the inverted position to an outwardly projecting position to enable ready access to a dispensing opening ( ) on the end wall ( ). An efficient and cost effective method for forming the container ( ) and an intermediate article ( ) formed during the method are also disclosed.
