A fitment for use in the discharge of pourable contents from a container wherein the constancy of uniform flow of contents from the container is minimally, if at all, adversely affected by the need for accommodating inflow of ambient air into the container as the contents are discharged from the container, the fitment including a conduit an exit end having an ellipsoidal cross-sectional geometry including a minor portion and an major portion, the geometry of the conduit exit being oriented uppermost toward (topwise of) the top end of the container. A method is disclosed.

Container fitment having ellipsoidal opening

The present invention discloses and teaches an improved fitment for use on paperboard, gable top liquid containers and the like. More specifically the present invention teaches a easy open tamper evident seal including a pull ring attached to the seal by means of a post having an aspect ratio of less than two thereby requiring less pulling force to break the tamper evident seal and remove it from the fitment spout.

Easy opening pour spout

An opening and closing device for a package containing a pourable product. The device is affixed to the package at the top end of the package and includes a ring affixed to the surface of the package. The ring encompasses an intended pouring opening which is prescored. A combination of a rupture element and a lever arm are hingedly mounted within the ring in position for activation of the rupture element through the lever arm, to rotate the distal end of the rupture element against the prescored region and to partly tear away a tab of the package. Further rotation of the rupture element carries the tab into the interior of the package. Provision is made for retention of the rupture element and tab within the interior of the package out of the flow path of contents being poured from the package through the opening formed by removal of the tab. A plurality of ribs disposed on that surface of the rupture element facing the package combine with the tab to define at least one air vent leading from the exterior to the interior of the package to facilitate uniform flow of the contents from the package. A lid is hinged to the ring for rotation into overlying relationship to the ring for reversible sealing relationship between the lid and the ring. A method for opening and closing a package is disclosed.
