ABSTRACT:
A closure for a container wherein the closure has a spout with flange, a cap and a link connecting the spout and cap. The link has a joint at its connection to the spout which allows for the folding of a portion of the link toward the flange for binding thereto. The link portion may be folded into a cutout on the flange. A method of securing the closure to a container includes bonding the link portion to the flange simultaneously with the binding of the closure to a thermoplastic surface of a container using an energy emission process such as ultrasonic sealing. The closure may also have a tamper evident structure attached thereon to provide a visual indication that the closure has been opened.
