Abstract 1. Method of making a container fabricated of thermoplastic material having at least one neck terminating in a protective cap covering a breachable sealing membrane said cap and said membrane being integrally formed with said container comprising: vertically extruding a heat softened tubular thermoplastic member into a vertically aligned and contiguous first confining zone and second confining zone; pinching closed the said tubular member near substantially the bottom of said second zone; forming at least two neck-like constrictions from said tubular member substantially at the top of said second zone; pinching closed, to form an integral breachable sealing membrane, all but one of said neck-like constrictions substantially near the top thereof; severing said tubular member near substantially the top of said first zone, thereby providing each neck-like constriction with an upwardly extending tubular portion; providing fluid pressure through the neck-like constriction with an upwardly extending tubular portion; providing fluid pressure through the neck-like constriction not pinched closed whereby the tubular member is inflated to the extent permitted by said second confining zone; then pinching closed the severed upwardly extending tubular portion and forming a removable cap from the closed tubular portion above the said breachable sealing membrane; and, pinching closed the severed upwardly extending tubular portion extending upwardly from the neck-like constriction through which fluid pressure was provided and forming a removable cap from closed tubular portion.
