| 20110192818 | RESEALABLE CLOSURES - A closure comprising a solid colour spout and a transparent overcap is adapted to be sealed to a container neck by means of a double-sided foil. The overcap has a depending valve, which engages with the spout to hold these components together prior to assembly to the container. The spout has a flange adapted to seat on a rim of the container neck and an annular wall that is received within the container neck. The foil is welded to the flange and is also used to weld the closure to a rim of a container neck of standard threaded design. The overcap can screw to an external thread on the container neck. The primary ex-factory seal is provided by welding the assembled closure to the neck. The secondary seal is provided by the engagement of the overcap valve with the spout. The invention discloses an improved method of assembly. | 08-11-2011 |

| 20090277859 | Cap Closure - A sealing arrangement for a plastic bottle includes a blow-molded bottle having a body and a mouth that includes an opening, an injection molded neck that includes a continuous wall that defines a top wall-opening and a bottom wall-opening. The top wall-opening provides a pour spout for liquid contained within the body of the bottle. The bottom wall-opening is fused to the mouth of the bottle so as to surround the bottle's opening. A removable flange is located generally within the bottom wall-opening and a frangible region connects the flange to the wall. A foil is secured to a side of the flange that is generally adjacent to the bottom wall-opening, and the foil is adapted to close the bottom wall-opening. A plurality of foil-cutting teeth are carried by the wall generally adjacent to the bottom wall-opening, generally adjacent to the side of the flange and generally adjacent to the foil. A pull member is secured to the flange. Manual operation of the pull member separates the flange from the wall, as at least a portion of the foil is cut by the teeth. An injection-molded cap removably closes the top wall-opening. The wall includes a weakened portion that will break upon an attempt to physically remove the wall from the bottle. The cap includes a cover plate that covers the top wall-opening and a skirt that extends from the cover plate to cover the weakened portion of the wall. | 11-12-2009 |
