  • Patent number: 7753255
    Abstract: A top closure obturating panel (2) of a carton is formed with a partial depth cut (4) in the form of an open loop of which one end (4a) is at a greater distance from a central zone of the loop (4) than is the other end (4b). Following filling and top-sealing of the carton, there is applied to the panel (2) a pour spout fitment consisting of a flanged pour spout, a screw cap on the pour spout, and a plunger co-operating with the screw cap and the pour spout in such manner that, upon unscrewing of the screw cap, the plunger screws inwards. At its inner end, the plunger is formed with arcuate pushing blades (6), which thereby cause the laminate material of the panel (2) to fracture along the partial depth cut (4) such that an encircling portion (2a) of the panel (2) and an encircled portion (2b) within the loop (4) separate from each other along the loop (4), but remain interconnected by way of an intermediate portion (2c) extending through between the ends (4a) and (4b) of the loop (4).

  • Patent number: 6257449
    Abstract: A reclosable fitment for a paperboard package having rear intrusion, anti-finger intrusion protection, and a raised spout to more naturally and directly allow the liquid within the container to be dispensed. The present invention provides a two piece fitment or closure having a base which is adapted to be attached about a scored area on a paperboard package. A lever is pivotally attached to the base and includes a rear portion which is adapted to open the scored area at a rear portion thereof. The rear portion is forced downwardly into the container by lifting upwardly on the forward portion of the lever. The forward portion of the lever has a built-in pouring spout which when placed into the open position forms a natural spout elevated away from the base to allow the liquid to more naturally and accurately be directed away from the package. A cover can be pivotally attached to the base to protect the lever from contaminates, and to automatically open the package upon lifting the cover away from the base.

    Abstract: A pouring element for attachment to a package containing flowable material, and having a pouring opening covered with a perforated or otherwise weakened material. The pouring element of the present invention allows for the opening of the package without contamination of the contents therein. In one embodiment of the pouring element, there exists an opening means that has an attached support element and which is hinged to a base plate portion of the pouring element. In conjunction with movement of a lid portion, the support element and opening means act to penetrate a tearable material covering a pouring opening of the package, thereby allowing the contents thereof to be dispensed. In another embodiment, the opening means may be a portion of the support element and may be affixed to the lid. After initial opening of the lid, the support element may position itself such that closing of the lid will cause penetration of the tearable material layer by the opening means, and thus the opening of the package.
