Dual-Container Fluid Packaging With Segmented Opening And Expulsion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging devices for multiple fluids combine the functionality of opening the separator between fluids and expelling the contents using a single flexible wall, requiring a compromise that can lead to inefficiencies in both functions.
Innovation Solution
A device comprising a first container with a dispenser and a second container, where the separator is opened by a movable wall with a striker and flange for leaktightness, and opening elements that allow the fluids to mix, while a flexible element in the first container facilitates expulsion of the mixture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single flexible wall is used to both open the separator and expel the contents, then the device structure is simplified, but the performance of both functions is compromised
Solution Approach 1:
The device divides the functionality into two separate components: a movable wall with striker for opening the separator, and a flexible element for expelling contents. This segmentation allows each component to be optimized for its specific function, resolving the contradiction between structural simplicity and functional performance.
Solution Approach 2:
The invention extracts the opening function from the flexible wall by introducing a separate movable wall with striker mechanism. This extraction allows the flexible element to focus solely on the expulsion function, improving overall system reliability while maintaining reasonable structural complexity.
2Reliability
If a movable wall with striker is added to separate the opening function, then the opening effectiveness is improved, but the device complexity increases
Solution Approach 1:
The movable wall combines multiple functions: it acts as a barrier to separate fluids during storage, provides a mounting surface for the striker to open the separator, and integrates the flange for sealing. This merging reduces the need for additional separate components, limiting the increase in device complexity.
Solution Approach 2:
The movable wall serves multiple purposes: fluid separation, striker mounting, and structural support for the opening mechanism. This multi-functionality improves opening effectiveness while minimizing the increase in overall device complexity.
3Productivity
If the separator is opened earlier to allow mixing, then the fluids can mix sooner, but product protection during storage is compromised
Solution Approach 1:
The device prepares the mixing function in advance by pre-positioning the movable wall and striker mechanism, but the actual mixing action is deferred until the user activates it by moving the flexible element. This preliminary preparation enables rapid mixing when needed while maintaining product protection during storage.
Solution Approach 2:
The system transitions from a static sealed state during storage to a dynamic mixing state when activated. The movable wall and flexible element remain in place during storage, protecting the products, and only when the user manipulates the flexible element does the system become dynamic, allowing rapid mixing.

AI summary
The invention relates to a device for packaging at least a first and a second fluid comprising an arrangement consisting of a first container for containing a first fluid and a second container for containing a second fluid,wherein the first container is substantially in the form of a tube, preferably in the form of a tube, the first end of which is provided with a dispenser and the second end of which is designed to attach said second container to this second end and thus close said second end of the first container,wherein the second container is substantially in the form of a tube, preferably in the form of a tube, the first end of which is designed to be attached to the second end of the first container, said first end of the second container being closed by means of a tearable wall, and the second end of which is closed by means of a movable wall, said movable wall being designed to be displaced in the direction of said tearable wall to open said tearable wall and thus allow the first and second fluid to mix with each other.
