ABSTRACT:
A package is provided including a container and a cap attached thereto. The container has an open and a closed end, the former having a dispensing opening surrounded by a shoulder. A pair of first buttresses are molded into the shoulder arranged along a cross-sectional major axis bisecting the opening. A pair of second buttresses are also molded into the shoulder and arranged along a minor axis bisecting the opening. Each of the buttresses have an upper edge tapering downwardly away from the opening. Upper edges of the second buttresses have a steeper taper angle than those of the first buttresses. The cap includes a lid hingedly connected to an edge of a fitment, the latter having a platform surrounded by a skirt wall and a product exit orifice formed in the platform. On a lower surface of the platform are four legs surrounding the orifice, projecting downwardly with each leg being asymmetrically shaped and lockingly fitted between first and second adjacent buttresses.
