Abstract
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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
163 words
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.
Claim 2
Dependent Claim
163 words
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.
Claim 3
Dependent Claim
97 words
The structure as defined in claim 1 wherein said strip includes a straw connected to and extending along the under surface thereof, a flexible resilient apron mounted on the strip and receiving the straw and connecting the straw to the strip for movement of the straw with the strip when pulled upwardly to expose the straw for use in consuming the contents of the container, said strip having an air channel in the under surface thereof by which air blown into the channel will deflect the apron downwardly to a vertical position for receiving the straw therethrough.
Claim 4
Dependent Claim
38 words
The structure as defined in claim 2 wherein said lid includes a distinguishably colored dot thereon to enable the lid to be oriented by lid and straw assembly machinery having a photocell assembly sensitive to the colored dot.
Claim 5
Dependent Claim
55 words
The structure as defined in claim 2 wherein said apron includes a central opening and radial cut lines receiving and gripping a staw when inserted therethrough, a lid-mounted-ferrous member being aligned with the apron to facilitate positioning of the lid in alignment with an air discharge and the straw when assembling the lid and straw.
Claim 6
Dependent Claim
55 words
The structure as defined in claim 4 wherein said lid includes a transverse score line at the permanently attached end of the tear-out strip defining a hinge about which the tear-out strip swings thereby preventing the strip from swinging back into contact with the facial area of a person consuming the contents of the container.
Claim 7
Dependent Claim
51 words
The structure as defined in claim 2 wherein said flexible apron includes a central small opening and a plurality of radial cut lines extending therefrom to define a plurality of pie-slice-shaped segments which are deflected when a straw is forced through the apron and frictionally gripping the periphery of the straw.
Claim 8
Dependent Claim
185 words
The structure as defined in claim 6 together with a ferrous insert in said lid and being exposed to the exterior only to enable handling and pick up of a non-ferrous lid by magnetic handling and pick-up equipment, said lid including a pair of adjacent, concentric, raised beads thereon, a score line between said beads to define a line of separation, said beads and score line having connecting portions adjacent the peripheral edge of the lid and terminal ends spaced inwardly from an opposite edge portion of the lid thus defining a tear-out strip having one end permanently of unitary construction with the lid, and a pull ring assembly attached to said strip adjacent the connecting portions of the beads, said pull ring assembly including a nose portion conforming with the connecting portion of the inner concentric bead and terminating in a downturned edge in overlying engagement with the connecting portion of the score line to facilitate breakthrough of the score line when the pull ring is elevated, said ferrous member being disposed between the terminal ends of the beads and edge of the lid.
Claim 9
Dependent Claim
38 words
The structure as defined in claim 1 together with a ferrous insert in said lid and being exposed to the exterior only to enable handling and pick up of a non-ferrous lid by magnetic handling and pick-up equipment.
Claim 10
Dependent Claim
91 words
The structure as defined in claim 1 wherein said lid includes a transverse score line therein at the end of the strip remote from the nose portion of the pull ring assembly to form a hinge for upward swinging movement of the strip and pull ring assembly to retain the strip and pull ring assembly permanently connected to the lid in peeled back open position, said transverse score line forming a stop for the ends of the score line and prevent flip back movement of the strip and pull ring assembly.
Claim 11
Dependent Claim
59 words
The structure as defined in claim 1 wherein said score line is defined by aligned depressed grooves in the top and bottom surfaces of the lid, said depressed grooves being generally V-shaped and formed by compacting metal in the side walls thereof rather than removing material thereby facilitating breakthrough by providing a snap break rather than a lacerated tear.
Claim 12
Dependent Claim
76 words
The structure as defined in claim 1 wherein said pull ring assembly and strip include a drawdown connection having a hollow interior defining a rigid connection located adjacent the nose portion whereby the nose portion will fulcrum with the drawdown connection when the end of the pull ring assembly remote from the nose portion is pivoted upwardly, said hollow drawdown including a riveted area peripherally thereof defining an enlarged fulcrum area for the pull ring assembly.
Claim 13
Dependent Claim
74 words
The structure as defined in claim 1 wherein said lid includes means thereon to facilitate proper orientation of the lid, means on the container to facilitate magnetic pickup when a non-ferrous container is used, and depending means to grippingly support and retain a straw with the lid after products have been consumed thereby retaining all components of the lid and container assembled to facilitate disposal thereof for providing an ecology benefitting lid and container.
