Dual Pouch Retaining Sheet for Compact Tear-Away Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional methods of packaging multiple pouches together result in excessive material use and larger footprints, leading to higher costs and potential issues with pouch separation during transport or consumption.
Innovation Solution
A food package design featuring a primary pouch with a secondary pouch secured via a retaining sheet that includes perforated regions, allowing the secondary pouch to be released when the primary pouch is opened, using minimal materials and ensuring easy, intentional separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If secondary packaging materials (boxes or bags) are used to package multiple pouches together, then the pouches are securely contained, but the overall footprint and cost increase
Solution Approach 1:
The patent merges the packaging function into the pouch structure itself by integrating a secondary pouch directly onto the primary pouch surface. This eliminates the need for separate external packaging materials like boxes or bags, thereby reducing overall footprint while maintaining secure containment of multiple pouches together.
Solution Approach 2:
The patent implements nesting by placing a secondary pouch on the outer surface of a primary pouch. This nested configuration allows multiple pouches to occupy the same spatial envelope, significantly reducing the overall footprint compared to traditional separate packaging while keeping both pouches securely contained.
2Reliability
If traditional secondary packaging is used, then pouches are contained securely, but material costs and waste increase
Solution Approach 1:
The patent combines the containment function with the pouch structure itself, eliminating redundant packaging materials. The secondary pouch is integrated onto the primary pouch, so no additional external packaging materials are needed, reducing material waste while maintaining secure containment.
Solution Approach 2:
The patent eliminates the need for disposable secondary packaging materials by integrating the containment structure into the pouch system itself. This reduces material waste and allows for more efficient use of packaging materials overall.
3Loss of substance
If pouches are packaged together without additional materials, then material use is reduced, but pouch separation during transport may occur
Solution Approach 1:
The patent applies preliminary action by providing adhesive elements on the primary pouch surface before the secondary pouch is attached. This pre-prepared adhesive surface ensures secure attachment of the secondary pouch, preventing separation during transport without requiring additional packaging materials.
Solution Approach 2:
The patent uses an adhesive element as an intermediary between the primary pouch and secondary pouch. This adhesive mediator creates a reliable bond that prevents pouch separation during transport while avoiding the need for bulky external packaging materials.
4Adaptability or versatility
If multiple pouches are packaged together, then product variety is increased, but access to individual pouches becomes difficult
Solution Approach 1:
The patent divides the packaging system into separable segments - a primary pouch and a secondary pouch that can be independently accessed. The secondary pouch is attached to the primary pouch but can be easily removed or opened separately, allowing users to access individual pouches without difficulty while maintaining product variety.

AI summary
A food package includes first and second pouches and a retaining sheet that removably secures the second pouch at an outer surface of the first pouch. The first pouch includes an opening element that provides access to the first pouch when a user performs an opening action on the first pouch. The retaining sheet includes a first portion adhered along an upper region of the first pouch, a second portion adhered along a lower region of the first pouch, and a third portion between the first and second portions that engages the second pouch to secure the second pouch between the retaining sheet and the first pouch. A perforated region connects the first and third portions and is configured to separate the third portion from the first portion when the user performs the opening action to at least partially release the second pouch from the first pouch.
