Frangible Tab Detachable Beverage Container Pack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bulk packaging of beverage containers generates excessive waste and is less aesthetically appealing compared to individual designer containers, despite being more cost-effective.
Innovation Solution
A detachable container pack design where thin, flexible tabs connect multiple containers end-to-end or in a chain, allowing for sequential detachment and use of the tabs as pull tabs for opening, reducing waste and maintaining structural integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If beverage containers are packaged in bulk (e.g., six-pack with plastic ring or case with twenty-four containers), then cost-effectiveness is improved, but packaging waste increases and aesthetics deteriorate
Solution Approach 1:
The bulk package is segmented into multiple individually detachable containers connected by frangible tabs. Each container can be separated and removed individually from the pack, allowing consumers to purchase in bulk while only disposing of minimal connecting material rather than entire rigid packaging structures.
Solution Approach 2:
The frangible tabs are designed to be easily broken and discarded after use, while the main container bodies are retained and used. This allows the majority of the packaging material to be recovered and kept, with only the minimal tab material being discarded after serving its connection purpose.
2Quantity of substance
If beverage containers are packaged in bulk, then cost-effectiveness is improved, but packaging aesthetics deteriorate
Solution Approach 1:
The bulk package is divided into individual container units that maintain their designer appearance, connected by minimal tabs. This segmentation allows each container to retain its aesthetic appeal while still being part of a bulk package for cost-effective purchasing.
3Ease of operation
If thin flexible tabs are used to connect containers, then ease of detachment is improved, but connection strength may be compromised
Solution Approach 1:
The tabs are designed with non-uniform properties: they are thin and flexible at certain locations to enable easy detachment, while maintaining sufficient strength at other locations to keep containers securely connected during normal handling and transport. This local variation in quality resolves the contradiction between ease of detachment and connection strength.
Solution Approach 2:
The tabs utilize material properties that allow parameter changes - specifically, the material is chosen to be frangible, meaning it can transition from a state of sufficient structural integrity to an easily breakable state with minimal force, enabling both strong connection and easy detachment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This design enables cost-effective bulk purchasing while minimizing waste and enhancing aesthetics by allowing easy separation and consumption of containers, with the tabs providing both connection and easy access for drinking.
Implementation Method 1
Each tab is relatively thin and flexible, having sufficient strength to normally keep the containers connected, yet frangible so that the tab may be broken by being bent or torn

AI summary
The individually detachable drink pack includes a plurality of beverage containers aligned in a substantially linear fashion. A tab is disposed about the periphery of the cap and/or base of each container and extends to the next container, attaching to the next container's base or cap to another tab. In this manner, the containers are attached end to end, or may be branched to start a side chain of containers, also linked end to end. Each tab is relatively thin and flexible, having sufficient strength to normally keep the containers connected, yet being frangible such that the tab may be broken by being bent or torn, thus allowing consecutive beverage containers to be separated and the contents thereof consumed.
