Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable food packages made of non-recyclable plastic or cardboard with inner foil face jamming issues during storage and transport, causing inefficiencies in automated filling processes.
Innovation Solution
A stackable product package design featuring outwardly folded rim members and bracket members at intermediate walls to maintain spacing between nested packages, using recyclable fiber material like corrugated paperboard, ensuring a gastight seal and preventing jamming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If packages are stacked nested for space saving, then storage efficiency is improved, but jamming occurs between packages making retrieval difficult
Solution Approach 1:
The package structure is segmented by introducing bracket members as separate structural elements attached to the package body. These brackets create discrete spacing zones between nested packages, allowing them to be stacked tightly for space efficiency while maintaining operational accessibility for retrieval.
Solution Approach 2:
Bracket members serve as intermediary elements between nested packages. These brackets physically intervene in the interface between packages, maintaining a controlled distance that prevents jamming while enabling space-efficient nested stacking and easy retrieval operations.
2Ease of operation
If bracket members are added to prevent jamming, then package retrieval ease is improved, but device complexity increases
Solution Approach 1:
The bracket members are merged with the package blank structure during manufacturing. The brackets are formed as integral parts of the molded package body, combining the spacing function with the package structure itself rather than adding separate components, thereby reducing overall device complexity.
Solution Approach 2:
The bracket members serve multiple functions: they provide spacing to prevent jamming, maintain structural integrity during stacking, and facilitate automated handling. This multi-functionality reduces the need for additional separate components, simplifying the overall package design.
3Object-affected harmful factors
If packages are made from recyclable fiber material, then environmental impact is reduced, but sealing reliability deteriorates
Solution Approach 1:
The package employs composite material construction with a recyclable fiber material body and an aluminum foil inner lining. This composite structure combines the environmental benefits of recyclable materials with the superior sealing properties of aluminum foil, achieving both ecological sustainability and sealing reliability.
Solution Approach 2:
Different material properties are applied to different parts of the package: the outer body uses recyclable fiber material for environmental sustainability, while the inner lining uses aluminum foil specifically at the sealing regions where gas-tightness is critical, optimizing both environmental and functional requirements.

AI summary
The invention relates to a stackable product package, a method of manufacturing the same and a product package blank. The stackable product package comprises a body part (2) provided with a bottom (3), and with walls (2a, 2b, 2c) in connection with the bottom (3), as well as with rim members (4a) folded outwards along folding lines (4e), at the top edge of the walls, and constituting a substantially planar rim portion (4), the body part (2) enclosing a receiving space for the product to be packed. At the lateral edges of each intermediate wall (2c) of the body part (1), and in proximity to a folding line (2e), bracket members (2f, 2g) are provided to keep the product packages (1), when nested, spaced apart.
