Abstract
Nestable packaging lids are described. Generally, the packaging lids include a generally planar lid member having an upper surface and a lower surface, a plurality of dome expansions extending upwardly from the lid member, and a plurality of elongate projections extending downwardly from the lower surface of the lid member. Each dome expansion defines a downwardly facing recess and includes a base perimeter defining a base center, and the dome expansions are arranged in longitudinal rows and transverse columns. In an implementation, at least one projection is disposed transversely between a longitudinally adjacent pair of dome expansions and at least one projection is disposed longitudinally between a transversely adjacent pair of dome expansions.

A nestable packaging lid, comprising:
- a generally planar lid member having an upper surface and a lower surface;
- a plurality of dome expansions extending upwardly from the lid member, each dome expansion defining a downwardly facing recess and including a base perimeter defining a base center, the dome expansions being arranged in longitudinal rows and transverse columns;
- and
- a plurality of elongate projections extending downwardly from the lower surface of the lid member, at least one projection disposed transversely between a longitudinally adjacent pair of dome expansions and at least one projection disposed longitudinally between a transversely adjacent pair of dome expansions.
A packaging system comprising:
- a nestable packaging lid including
- a generally planar lid member having an upper surface and a lower surface,
- a plurality of dome expansions extending upwardly from the lid member, each dome expansion defining a downwardly facing recess and including a base perimeter and a base center, the dome expansions being arranged in longitudinal rows and transverse columns, and
- a plurality of elongate projections extending downwardly from the lower surface of the lid member, at least one projection disposed transversely between a longitudinally adjacent pair of dome expansions and at least one projection disposed longitudinally between a transversely adjacent pair of dome expansions;
- and
- a nestable packaging base including
- a base member having an upper surface and a lower surface,
- a plurality of pockets defined in the base member, each pocket disposed for alignment with a corresponding dome expansion of the nestable packaging lid, and
- a plurality of posts extending upwardly from the base member, each post disposed between a diagonally adjacent pair of pockets, the posts configured to support the nestable packaging lid.
