Stacking Drawer Package Shared Sleeve Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing packaging for multiple pizzas requires separate boxes with individual covers, leading to excessive material usage and waste, as people often order multiple pizzas at once.
Innovation Solution
A container design featuring a shared sleeve for multiple containers, allowing for a single cover to be used for multiple pizzas, reducing material consumption and waste by using score lines, slits, and friction tabs to securely stack and hold the containers together.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate boxes with individual covers are used for multiple pizzas, then each pizza is securely packaged, but material usage and waste increase significantly
Solution Approach 1:
Multiple individual pizza boxes are merged into a single shared packaging system. The patent shows multiple pizza containers stacked within one outer box with a single shared cover, eliminating the need for separate covers on each box while maintaining individual container integrity for food security.
Solution Approach 2:
The outer box and single cover serve multiple functions simultaneously: they protect multiple individual pizzas, provide a unified shipping container, enable stacking for space efficiency, and reduce material consumption. This multi-functional design replaces what would traditionally require separate packaging for each pizza.
2Reliability
If multiple separate boxes are used for multiple pizzas, then each pizza is individually protected, but the packaging cost and material waste increase
Solution Approach 1:
The patent combines multiple individual pizza containers into one shared outer packaging structure. Instead of using separate boxes and covers for each pizza, the invention uses a single outer box with a single cover that encloses multiple individually protected pizza containers, reducing total material quantity.
Solution Approach 2:
Individual pizza containers are nested within the outer box structure. The patent shows smaller individual pizza boxes stacked inside a larger outer container, with the single cover enclosing all nested containers. This nesting arrangement protects each pizza individually while using fewer total materials than separate packaging.
3Loss of substance
If a shared sleeve is used for multiple containers, then material usage is reduced, but the complexity of stacking and securing containers increases
Solution Approach 1:
The packaging system is segmented into distinct functional components: individual pizza containers with their own lids for food protection, and an outer box with a single shared cover for shipping and stacking. This segmentation allows each component to perform its specific function while working together as an integrated system.
Solution Approach 2:
The outer box acts as an intermediary structure between individual pizza containers and the external environment. It provides the stacking interface and shared cover mechanism, mediating between the need for individual protection and the need for material-efficient bulk packaging.

AI summary
A tray has a bottom panel, side and end panels and top shoulders at opposed ends of the tray. The tray is covered by a separate sleeve that extends across the top of the tray and down opposed sides and across the bottom of the tray. The trays may be stacked with an upper tray resting on the shoulders of the lower tray. The sleeve is a sleeve for the stack of trays with the side panels of the sleeve sized for different numbers of trays in the stack. There may be frictional tabs in the side panels of the tray or trays which have frictional engagement with the side panels of the sleeve.
