Abstract
Abstract The invention relates to a moulded container of the type commonly made from wood pulp fiber and used for packaging eggs. The container has a cover with an opening through which eggs contained in cells in the tray portion can be viewed. The cells are partially defined by a series of posts and the cover has a rib that engages with the tops of the posts. The viewing opening is on either side of the rib and there is provision in the cover for resilient fingers that extend downwardly and outwardly of the rib and into the cell to engage with an egg to stabilize it in its respective cell.
