Nested Container Package with Flexible Inner Bag for Product Visibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pressurizable packages face challenges in maintaining aesthetic appeal and functionality while allowing product visibility, especially when containing multiple separated products, as they may deform unattractively as the product is depleted.
Innovation Solution
A package design featuring clear or translucent outer and inner containers with a common dispensing system, allowing visibility of the products and using a plastic valve cup assembly that simplifies assembly and reduces material usage, along with optional flexible inner containers that collapse upon depletion for aesthetic and complete product usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If flexible packaging is used to allow product visibility, then the user can see how much product is left, but the packaging assumes aesthetically undesirable configurations as the product is depleted
Solution Approach 1:
The package is divided into an outer container and an inner flexible bag, where the rigid outer container maintains aesthetic appearance while the inner flexible bag contains the product. This segmentation allows the outer container to preserve its shape while the inner bag deforms during dispensing, resolving the contradiction between visibility and aesthetics.
Solution Approach 2:
The rigid outer container acts as an intermediary between the flexible inner bag and the external environment. It shields the aesthetic appearance from the deforming inner bag while still allowing product visibility through transparency, thus mediating between the conflicting requirements of aesthetics and visibility.
2Adaptability or versatility
If multiple products are contained in the same package, then product variety is increased, but the packaging complexity and difficulty of maintaining separation increase
Solution Approach 1:
Multiple products are segregated into separate compartments or inner bags within the outer container. This segmentation maintains product separation and prevents interaction while allowing multiple products to be contained in a single package, resolving the contradiction between versatility and complexity.
Solution Approach 2:
Inner flexible bags containing different products are nested within the outer rigid container. This nesting arrangement allows multiple products to be contained in a compact, organized manner while maintaining simplicity in the overall package structure and ensuring product separation.
3Loss of information
If clear or translucent containers are used for visibility, then product visibility is improved, but material selection and manufacturing complexity increase
Solution Approach 1:
The package uses a rigid outer container made of clear or translucent material for visibility, while the inner flexible bag can be made of different materials optimized for product containment. This segmentation allows each component to be manufactured independently with appropriate material properties, simplifying the overall manufacturing process while maintaining visibility.
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
The design maintains product visibility and aesthetic appeal, ensures complete depletion of contents, and simplifies assembly while reducing material usage and assembly time, addressing the challenges of multiple product containment and deformation issues.
Implementation Method 1
Motive force for dispensing the product from the package include gaseous propellants... product dispensing occurs due to the pressure differential between the product and the ambient
Implementation Method 2
Motive force for dispensing the product from the package include... elastic bladders

AI summary
A package for containing a product therein. The package comprises plural containers (12,14,16), one disposed inside the other. The outer container allows an inner container to be visible from outside the package. The inner container may also allow product therein to be visible from outside the package as well. If desired, plural inner containers may be utilized in series or in parallel.
