Abstract

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.
