A cap assembly cooperates with a container to form a vent portion and a pour portion when a cap is oriented in an open position relative to the container. The cap is dimensioned to seal the container opening in a closed position. The cap and opening are oblong, preferably oval in configuration, and have cooperating thread assemblies that permit the cap to be selectively rotated between the open and closed positions. The cap preferably has a threaded shank that is engaged along a portion of its periphery by central threaded portions disposed on opposite sides of the generally oval container opening.

A cap assembly for a container having a flowable product to be poured from the container, the cap assembly comprising: a cap; an opening in the container dimensioned to receive the cap; a one-quarter turn thread assembly interconnecting the cap and container; the container opening sealing receiving the cap in a first, closed position; and defining a vent portion and a pour portion on opposite sides of cap thread means when the cap is disposed in a second, open position; wherein the opening has a generally oval configuration; and wherein the one-quarter turn thread assembly includes opening thread means is located at opposite ends of a minor axis of the generally oval configuration. 3. The cap assembly of claim 2 wherein the vent portion and the pour portion are located at opposite ends of a major axis of the generally oval configuration. 4. A cap assembly for a container having a flowable product to be poured from the container, the cap assembly comprising: a cap; an opening in the container dimensioned to receive the cap; a one-quarter turn thread assembly interconnecting the cap and container, the container opening sealing receiving the cap in a first, closed position and defining a vent portion and a pour portion on opposite sides of the cap when the cap is disposed in a second, open position; wherein the cap has a generally oval configuration and the one-quarter turn thread assembly includes an externally threaded shank; and wherein the container opening has a generally oval configuration that sealingly receives the cap. 5. The cap assembly of claim 4 wherein the one-quarter turn thread assembly includes cap thread means having a cylindrical portion with external threads thereon. 6. The cap assembly of claim 5 wherein the cap thread means has a helical conformation. 7. The cap assembly of claim 5 wherein the cap thread means includes a linear portion that allows the cap to be axially moved relative to the container opening. 8. The cap assembly of claim 4 further comprising a retainer for retaining the cap on the container.
