Claim 4

A liquid pourout fitment and removable screw closure in combination with a bottle adapted to contain a liquid, said bottle having an exteriorly threaded neck portion for selectively applying the closure thereto, said neck portion having a rim defining an opening for said bottle and defining an annular snap-on groove intermediate the rim and said threads; said fitment comprising, a disc element having a centrally located opening therethrough and an annular bottle neck engaging member on the periphery of said disc, an integral, axial, hollow pouring tube surrounding the periphery of said opening and extending vertically above and below the plane of said disc element, said pouring tube being outwardly flared at its upper extremity, said flared portion terminating in a substantially vertical end portion, and having an inwardly directed flange at its lower extremity, a tapered, axial, hollow vent tube having a maximum outside diameter less than the inside diameter of said pouring tube and being located concentrically with respect to said pouring tube, said vent tube being integrally connected to said inwardly directed flange by a plurality of rib members to thereby define a plurality of openings to allow escape of a liquid within said bottle, said tapered vent tube having an upper portion, defined by an outside diameter tapering toward said pouring tube and terminating at a location intermediate said inwardly directed flange and said upper extremity of said pouring tube, and a lower portion, integrally connected to said upper portion, defined by an outside diameter tapering away from said pouring tube and terminating at a point below said inwardly directed flange, the outside diameter of said lower portion being less than the outside diameter of said upper at the point of connection of said upper and lower portions, the difference in outside diameters of said upper and lower portions serving to define a flow diverting ledge, the inside diameter of said vent tube tapering uniformly from a first inside diameter adjacent the smallest outside diameter oF said upper portion to a second inside diameter, smaller than said first inside diameter, adjacent the termination of said lower portion of said vent tube; said screw closure comprising a skirt portion formed with threads on its interior surface for securing said closure to the threads of said bottle neck, an upper, substantially horizontal panel, a lower, parallel, substantially horizontal panel integrally connected to said skirt, said upper and lower panels being integrally attached by a vertically extending annular wall, an annular, downwardly depending sealing bead radially, inwardly spaced from said annular wall attached to the interior surface of said upper panel, said bead having a diameter greater than the outside diameter of said vent tube, the outer wall of said bead being tapered to match the flare of the upper portion of said pouring tube, a downwardly depending, annular engagement bead integrally formed on the lower surface of said lower parallel panel, and an annular sealing groove, said sealing groove having its outer wall defined by said annular wall and its inner wall defined by the outer wall of said annular, downwardly depending sealing bead, the width of said sealing groove being such that, upon engagement of said closure and said fitment, the outer wall of said sealing bead will sealingly engage the inner flared wall of said pouring tube and the inner wall of said annular wall will sealingly engage the vertical end portion of said flared upper extremity of said pouring tube, the engagement of said fitment and said closure being limited by the abutment of said disc element of said fitment and said downwardly depending, annular engagement bead formed on the inner surface of said lower, parallel panel.
