The lid comprises a base portion 305 to which a cap portion 307 of the lid is pivotally mounted by a hinge to allow the cap portion 307 to transition between open and closed position. A plug is inserted and attached to at least partially or fully seal an aperture formed at the base portion 305. The plug has at least one orifice 314 functioning as an egress opening through which a flowable material stored in the housing 302 can dispense.
