Reconfigurable Container-Closure System for Dual-Product Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multi-compartment container systems fail to effectively protect ingredients from degradation until the time of first use, leading to unnecessary excess ingredients and potential chemical reactions that may degrade product efficacy or safety.
Innovation Solution
A reconfigurable container-closure system comprising two containers and closures that maintain separation until the user initiates mixing by attaching the second reservoir to the first container, allowing products to mix when the second closure is screwed onto the first container, ensuring protection from environmental degradation and efficient use of ingredients.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ingredients are kept separate in multi-compartment containers, then product efficacy is maintained, but device complexity increases
Solution Approach 1:
The system divides the container into separate compartments (first container with first product, second container with second product) that remain physically separated until use. This segmentation prevents unwanted chemical reactions and maintains product efficacy while allowing simple user operation through straightforward separation and combination actions.
Solution Approach 2:
The closure mechanism merges the two separate container systems into a unified structure that maintains separation during storage but allows easy combination upon use. The closure integrates sealing and positioning functions to enable simple user operation while maintaining product integrity throughout storage.
2Reliability
If ingredients are protected from environmental degradation, then product efficacy is maintained, but loss of substance occurs due to unnecessary excess ingredients
Solution Approach 1:
The system performs preliminary separation of ingredients into distinct containers before use, protecting each ingredient from environmental degradation and unwanted reactions. This preliminary action ensures that ingredients remain in their optimal state until the moment of use, preventing degradation while allowing precise dispensing of only the required amounts.
Solution Approach 2:
The system changes the physical state and position of ingredients from separated and protected to combined and active upon use. This parameter change enables precise control over when and how much of each ingredient is dispensed, eliminating waste from excess ingredients while maintaining efficacy during storage.
3Ease of operation
If mixing is initiated early, then product preparation is simplified, but harmful chemical reactions occur that degrade product safety
Solution Approach 1:
The system segments the chemical components into separate physical containers, preventing unwanted chemical reactions while maintaining ease of operation. Users simply need to separate and combine the containers, avoiding complex preparation steps while eliminating harmful reactions through physical isolation.
Solution Approach 2:
The closure acts as an intermediary mechanism that controls the interaction between the two products. It maintains separation during storage but enables controlled combination upon use, preventing harmful chemical reactions until the user intentionally initiates mixing through the closure mechanism.

AI summary
A reconfigurable container-closure system is comprised of first (10) and second containers (110) and first (12) and second closures (112). The container-closure system can assume either of two configurations. The first configuration means that the first closure (12) is secured to the first container (10), and the second closure (112) is secured to the second container (110). Also, an orifice reducer, cartridge and piston are all attached to the second closure (112), and two products are separated. Second configuration means that the second closure (112) is secured to the first container (10), and the first closure (12) is secured to the second container (110). Also, the orifice reducer, cartridge and piston are all attached to the first container (10), and two products are allowed to mix and be dispensed. The transfer is accomplished by a user who simply screws the second closure (112) onto the first container (10).
