Abstract:
1. An apparatus for forming a finger-engaging portion in a stay-on-tab attached as a lever to an upper surface of a lid of a container to depress a scored part of the lid, wherein the stay-on-tab has an inner extremity, an opposed outer extremity, and an intermediate portion between the inner and outer extremities, the apparatus comprising: a support; a fixture including a top end that faces away from the container and a bottom end with a bracing face that faces towards the container, the fixture mounted to the support for movement relative to the support and along a longitudinal axis that extends through the container and the top and bottom ends of the fixture between a first position farther away from the container and a second position with the bracing face applied to a top of the stay-on-tab at the intermediate portion; and an abutment positioned on a lateral side of the fixture and mounted to the fixture for movement in a plane of motion between an open position that is away from the bracing face and a closed position that is towards the bracing face with the open position being a greater distance from the longitudinal axis than the closed position; the abutment being aligned with the bracing face with the plane of motion intersecting with the fixture, the abutment configured to move towards the bracing face and contact the stay-on-tab in the closed position and act in concert with the bracing face to bend the stay-on-tab between the fixture and the abutment at the intermediate portion of the stay-on-tab with the outer extremity of the tab moving upward relative to the longitudinal axis to form a finger-engaging portion in the outer extremity of the stay-on-tab that is upturned relative to the inner extremity of the stay-on-tab and the upper surface of the lid.
