Reclosable Battery Package With Sliding Pouch Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing battery packages are difficult to open without tools, prone to unintentional opening during transport, and allow unneeded batteries to fall out, leading to clutter and potential damage.
Innovation Solution
A reclosable battery package design featuring slidable pouches with angled perforations and locking mechanisms that allow easy access and re-closure, preventing accidental opening during handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If perforations are added to make the package easier to open, then ease of operation is improved, but reliability deteriorates due to unintentional opening during transportation
Solution Approach 1:
The package transitions from a static sealed state to a dynamic opening state through a controlled tearing motion. The user must actively pull the package apart along the perforation line, creating a deliberate mechanical action that prevents accidental opening while maintaining ease of use.
Solution Approach 2:
The package is divided into separable sections with perforation lines that guide the tearing action. This segmentation allows the package to be easily opened along predetermined lines while the remaining portions stay intact and securely sealed, preventing unintentional opening of the entire package.
2Ease of operation
If the package is opened to access batteries, then ease of operation is improved, but loss of substance worsens as unneeded batteries fall out
Solution Approach 1:
The package opens into two separate sections, allowing the user to access only the needed batteries while the other section remains sealed and contains the unneeded batteries. This segmentation prevents batteries from falling out entirely as the package structure maintains containment in both sections.
Solution Approach 2:
The perforation line acts as an intermediary that allows controlled access to batteries. By tearing along this line, the user creates a deliberate opening mechanism that prevents uncontrolled battery release, enabling selective removal of needed batteries while keeping unneeded ones contained.
3Manufacturing precision
If a utensil is required to open the package, then manufacturing precision is improved with sealed packaging, but ease of operation deteriorates when utensils are not available
Solution Approach 1:
The package incorporates pre-formed perforation lines that create weak points designed for manual tearing. This segmentation allows the package to maintain sealed integrity during manufacturing and transport while enabling easy manual opening without requiring cutting utensils, resolving the contradiction between sealed packaging and ease of opening.

AI summary
A reclosable battery package (10) includes a first panel (12) having a first removable portion (22) and a second panel (14) optionally having a second removable portion (26). A pouch (30) is disposed between the first panel (12) and the second panel (14). The first panel (12) and the second panel (14) are joined along perimeter edges (40, 42) and a pouch perimeter flange (32) is disposed between the first panel (12) and the second panel (14). The pouch (30) is slidably movable between the first panel (12) and the second panel (14) when the first removable portion (22) is removed from the first panel (12) to expose contents stored within the pouch (30).
