Abstract
A thermoplastic container which is blown, filled and hermetically sealed in a single forming and filling operation. The removable cap integrally formed therewith normally hermetically seals the container and has a peripheral side wall, a horizontal flange portion which merges with the neck portion and an annular groove which is formed in the horizontal flange portion and provides a weakened severing line for removing the cap. A pull tab having a narrow in width, vertically disposed tab flange is integrally connected with the horizontally extending flange portion and has means for gripping the pull tab to pivotally manipulate the pull tab outwardly from the container. The pull tab on being pivotally manipulated causes the horizontally extending flange portion to sever at the annular groove, thereby permitting the cap to be removed from the container.
