A container lid with a tear-out strip forming a closure therefor in which the strip and its pull ring remains attached to the lid and container while enabling the contents to be removed by utilizing a straw disposed within the container which will pop up into position for use when the tear-out closure is elevated by using the pull ring. When an aluminum lid or non-ferrous lid is used, an insert of ferrous material is mounted in sealed relation on the container lid or on the container bottom in the event a two-piece can is used which enables pick-up and handling of discarded containers by using magnetic devices to facilitate recycling of the containers. The straw is supported by a plastic apron and the lid provided with an air channel to enable the apron to be positioned in a vertical position for receiving an end portion of the straw therethrough. The tear-out closure and pull ring are constructed so that the pull ring may initiate breakthrough of the tear-out closure with application of a relatively small force. The lid is also provided with means for enabling it to be oriented in a machine for assembling the straw and lid for association with the container.
A container closure comprising a lid forming the end of a container, a pair of closely spaced generally parallel and concentric beads formed in the lid and projecting upwardly from the upper surface thereof, the beads being interconnected by a pair of connecting bead portions thus forming generally U-shaped outer and inner beads, a score line between said beads to define a line of separation, said beads and score line having terminal ends spaced from an edge of the lid and defining a tear-out strip, a pull ring assembly attached to the lid and overlying the inner bead and the connecting bead portion thereof with the pull ring assembly including a nose portion conforming with the connecting portion of the inner bead and overlying and contacting the score line between the connecting bead portions to provide breakthrough between the beads for pulling the tear-out strip upwardly and leaving the end thereof remote from the connecting portions of the beads attached to the lid.
