Abstract
A container and closure package in that includes a container having a body, a finish wall extending from the body with at least one external thread, a circular throat at an axial edge of the finish wall remote from the body and having a lesser inner diameter than the finish wall, and a pour spout extending axially from the throat at greater inner diameter than the throat. The container body, finish wall, throat and pour spout are of integrally blow molded construction as formed, with the inside diameter of the throat being optionally reamed as required for sealing engagement with the closure. The closure has a base wall, a peripheral outer skirt extending from the base wall with an internal thread for receipt over the external thread on the container finish wall, and an internal skirt extending from the base wall and spaced radially inwardly from the outer skirt for sliding plug-sealing receipt within the throat, with the pour spout being disposed between the inner and outer skirts of the closure.
