Abstract
A one piece plastic closure is provided for a container having a retention bead. The enclosure includes a top panel with a skirt interlocked with the retention bead. A removable tear strip on the skirt includes a pull tab to facilitate the grasping thereof. A lift tab, connected to the upper portion of the skirt, facilitates removal of the closure after the tear strip has been torn away from the enclosure to remove its interlocking with the retention bead. A frangible bridge interconnects the pull tab and the lift tab and pulls the lift tab into a more accessible position as the tear strip is removed.

A closure for a container having a retention bead comprising:
- a one-piece plastic body having a top panel;
- an encircling skirt depending from the top panel and integrally attached thereto;
- a locking means on the skirt for interlocking with said retention bead to retain the closure on the container;
- a removable tear strip on the lower portion of the skirt for removal to indicate that the closure has been opened;
- a pull tab integral with the tear strip and located at one end thereof for grasping to tear the tear strip from the skirt;
- means providing a line of weakness in the skirt and defining a breakable connection between the lower tear strip and an upper portion of the skirt;
- a lift tab connected to the upper portion of the skirt for facilitating removal of the closure after the tear strip has been torn at the line of weakness;
- a frangible bridge means interconnecting the pull tab and the lift tab for pulling the lift tab into a more accessible position during the removal of the tear strip, and
- means providing an increased cross sectional thickness portion between said lift tab and skirt to prevent the detaching of the lift tab completely from the skirt and assuring a fracturing of the bridge means.
A closure for a container having a retention bead comprising:
- a top panel;
- a depending skirt extending about periphery of the top panel and extending downwardly from said top panel;
- a locking means on the skirt for engaging the retention bead on the container to hold the closure on the container;
- a removable tear strip on the lower portion of the skirt having a line of weakness connection with an upper portion of the skirt;
- a pull tab for the removable tear strip molded integrally with the tear strip to be pulled to tear the tear strip at the line of weakness to detach the tear strip from the skirt;
- a lift tab connected to the skirt and hinged about an axis to be bent outwardly from the skirt to be accessible to lift the closure from the container, and
- means extending from the pull tab to the lift tab to pull the lift tab to its outward accessible position with pulling of the pull tab and tear strip from the skirt.
