ONE-PIECE MOLDED FLIP CAP CLOSURE

WIPO Patent Application WO1998019918

A3

A container having a resealable closure thereon is produced by a method including the steps of providing a closure having a spout and a flange and a stem projecting therefrom, placing the closure about an access area of the container and welding the closure to the container body thereby bonding at least one portion of a hinge to the spout. The closure stem defines an aperture and the cap has a lid and skirt projecting therefrom. The skirt is configured to prevent interference during pouring of the contents of the container. The hinge assembly connects the cap to the spout and allows for reclosable opening of the cap from the spout while maintaining the attachment of the cap with the spout. A tamper-evident structure is formed integrally with the cap including a removable portion secured to the closure by a breakable joint. The closure further includes an orienting projection for orienting the closure on the container at a predetermined location and position.
