Nestable Packaging Lid With Dome Expansions and Projections
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional egg and fruit trays experience high breakage and damage during delivery and storage due to instability and lack of secure packaging, especially with larger quantities, and existing solutions are costly and not tamper-proof.
Innovation Solution
A nestable packaging lid system with dome expansions and elongate projections that securely hold items, allowing for stacking and nesting with a base, using a wrap material for securement, which is cost-effective and provides improved stability and tamper evidence.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional egg trays are used for large quantities, then storage capacity is increased, but stacking stability deteriorates
Solution Approach 1:
The lid incorporates downwardly extending projections that nest into corresponding recesses in the tray, creating an interlocking configuration. This nesting mechanism provides stacking stability for large quantity packages while maintaining the increased storage capacity needed for retail competitiveness.
2Illumination intensity
If transparent lids are used, then product visibility is improved, but manufacturing cost increases
Solution Approach 1:
The invention uses an opaque or translucent lid made from cost-effective materials like molded fiber or plastic that can be easily manufactured. While not fully transparent, these materials provide sufficient visibility for retail display while dramatically reducing manufacturing costs compared to fully transparent lids.
3Ease of manufacture
If conventional packaging is used, then manufacturing cost is reduced, but item security deteriorates
Solution Approach 1:
The lid is segmented into multiple functional elements including dome expansions for individual item protection, elongate projections for securing items, and peripheral edges for tamper evidence. This segmentation provides enhanced security features while maintaining cost-effectiveness through efficient molding processes.
Solution Approach 2:
The lid can be manufactured in various colors or with color-coded features that indicate tamper evidence or product information, providing enhanced security and information delivery without significantly increasing manufacturing complexity or cost.
4Quantity of substance
If larger package sizes are used, then retail competitiveness is improved, but retail space efficiency deteriorates
Solution Approach 1:
The interlocking lid and tray configuration enables stable vertical stacking of multiple large-package units. This nesting capability allows retailers to store and display larger package sizes efficiently by maximizing vertical space utilization rather than requiring additional floor area.

AI summary
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.
