ABSTRACT:
A dome shaped crown for a clamshell container is formed by two sets of sidewalls having different shapes. A narrow space is provided between adjacent pairs of sidewalls, the spaces permitting venting of warm, moist air due to the presence of a heated sandwich packaged in the container. The container is formed from a unitary blank of paperboard. In one embodiment, the crown is dome shaped and the lower tray is provided with straight walls. In the second embodiment, both the crown and the lower tray have sidewalls of different slopes. Any type of releasable latch between the two halves may be employed.
