Elastomeric Base for Bottom-Dispensing Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bottom-dispensing containers face challenges with leakage due to impact, especially during storage and handling, as internal pressure changes can cause hydraulic hammer pressure, leading to unwanted valve opening and liquid leakage, and existing solutions like impact resistance systems add complexity and are difficult to clean.
Innovation Solution
A bottom-dispensing package with a resiliently squeezable container and a base made partially from an elastomer, featuring a slit-valve and an impact resistance system, which includes a housing with a compressible substance to absorb transient pressure increases, reducing leakage and enhancing durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If impact resistance systems are incorporated to reduce leakage due to impact, then leakage resistance is improved, but device complexity increases and cleaning difficulty increases
Solution Approach 1:
The base is made from an elastomeric material that is flexible and resilient, allowing it to deform and absorb impact energy while maintaining a simple, smooth structure that is easy to clean. This flexible base prevents leakage through impact without requiring complex mechanical impact resistance systems.
2Reliability
If impact resistance systems are incorporated to reduce leakage due to impact, then leakage resistance is improved, but ease of cleaning deteriorates
Solution Approach 1:
The elastomeric base provides a smooth, non-porous surface that is easy to clean and does not trap residual liquid. The flexibility of the material allows it to be simple in structure while still effectively absorbing impact energy to prevent leakage.
3Reliability
If a closing cap is added to prevent leakage, then leakage resistance is improved, but ease of operation deteriorates due to additional opening and reclosing steps
Solution Approach 1:
The resilient base automatically closes the orifice when not in use through its elastic properties, eliminating the need for a separate closing cap. The base opens and closes automatically based on pressure changes, providing self-service leakage prevention without additional user steps.
4Stability of the object's composition
If the container is made more rigid to prevent deformation, then structural stability is improved, but impact resistance deteriorates
Solution Approach 1:
The elastomeric base is specifically designed to be flexible and resilient, allowing it to deform and absorb impact energy. This flexibility is inherent to the material properties and provides effective impact resistance without requiring additional structural modifications.

AI summary
The need for alternative means of reducing leakage from bottom-dispensing packages (1) due to impact, especially for durable and reusable bottom-dispensing containers, is met by providing the bottom-dispensing package (1) with a base, and making the body of the base at least partially from an elastomer.
