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.
Abstract: A one-piece closure cap for a dispensing container. The cap, which is captive on the container body, is threadedly mounted for restricted rotation on the neck of the container so that upon elevation of the cap there is established a product release passage from the mouth of the container through product discharge ports formed in a surmounting top wall of the cap. Mechanical stops are provided to limit the degree of threaded rotation of the closure cap on the neck of the container to preclude inadvertent separation of the cap from the body of the container. The container neck is also formed adjacent an upper end thereof with a radially outwardly extending annular sealing bead which engages and stressingly abuts a circumscribing facing inner wall of the cap to prevent contents of the container from contaminating the threads of the closure assembly.
