1. A fitment for a container having a top end and a first wall associated with the top end and an opening extending through the thickness of the first wall, the fitment comprising:
a circumferential flange member adapted to engage the first wall of the container in circumscribing relationship to the opening through the top wall for mounting of the fitment to the container, the flange member defining a first plane adjacent to the opening; a second wall upstanding from the flange member and defining a conduit having an inner wall and entrance and exit ends through which contents of the container may be discharged, the exit end defining a second plane, the second wall having a circumferential projection extending radially therefrom adjacent to the exit end; at least the exit end of the conduit having a substantially ellipsoidal planar cross-sectional geometry having a major portion and a minor portion, wherein the ellipsoidal planar cross-sectional geometry has a height-to-width aspect ratio greater than 1; the minor portion being disposed vertically above the major portion when the fitment is affixed to the first wall of the container and the container is oriented in a direction for discharge of the contents of the container through the opening and substantially simultaneous ingress of ambient air into the container through the minor portion of the fitment; a tear away membrane with a tamper evident membrane portion disposed across and releasably engaging the inner wall of the conduit at a location fully within the conduit, the conduit having a substantially constant cross-sectional area between the entrance and exit ends, wherein the first wall associated with the top end of the container will be in a third plane between the membrane portion and the flange member, and the membrane portion having a perimeter releasably joined to the inner wall of the conduit in a fourth plane spaced apart from the flange member and positioned between the second and third planes, whereby the membrane portion closes the conduit, the tear away membrane including a pull ring affixed to the membrane portion adjacent to the minor portion of the conduit and configured to provide for localization of an initial tear away force applied through the pull ring to the tamper evident membrane portion adjacent to the minor portion of the conduit; and a cap member integrally attached in hinged relationship with the second wall defining the conduit adjacent to the exit end of the conduit and adjacent to the minor portion, the cap having an annular receiving area between first and second annular projections extending away from a cap top wall, one of the first or second annular projections having a circumferential groove that receives therein the circumferential projection of the second wall when the cap is in a closed position covering the exit end, the annular receiving area configured to receive therein in a sealing engagement an outboard rim of the second wall to thereby releasably close and seal the conduit against the passage of the contents of the container therethrough, and wherein the first annular projection of the cap member is radially outward of the second annular projection, and the cap member has a hinge member integrally connected to the first annular projection at the top cap wall and integrally connected to the second wall defining the conduit, the first annular projection having an opening therein immediately adjacent to the hinge member and configured to receive a portion of the hinge member therein when the cap is in the closed position and in sealable engagement with the exit end of the second wall. |
