Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing durable bottom-dispensing containers face challenges in providing sufficient elasticity for easy dispensing and quick rebound, while also being resistant to stress-cracking and easy to clean, especially when containing low-shear viscosities like detergents and cleaning compositions.
Innovation Solution
A resiliently squeezable container with a container wall made from elastomers, featuring circumferentially oriented grooves on the interior surface and a base with an impact resistance system, which allows for easy dispensing and reduced leakage, and is designed for repeated use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the container is made from elastomer to provide sufficient elasticity for easy dispensing and quick rebound, then the container's elasticity and rebound capability are improved, but the container wall thickness must be increased which makes dosing more difficult and the container harder to clean
Solution Approach 1:
The patent applies local quality by creating grooves at specific locations on the container wall to provide localized flexibility enhancement. The grooves are positioned to allow the container to be squeezed more easily at those specific points while maintaining overall structural integrity and manageable wall thickness for dosing operations.
Solution Approach 2:
The container wall is segmented by introducing grooves that divide the wall structure into sections. This segmentation allows the wall to flex and deform more easily during squeezing operations, improving dispensing ease without requiring a uniform increase in wall thickness throughout the entire container.
2Reliability
If the container wall is made from elastomer to resist stress-cracking upon repeated use, then the container's durability is improved, but the exterior surface becomes harder to clean
Solution Approach 1:
The grooves are positioned on the interior surface of the container wall, leaving the exterior surface smooth and free of crevices. This allows the exterior to maintain easy cleaning properties while the interior grooves provide the necessary flexibility and stress distribution to prevent cracking during repeated use.
3Ease of operation
If the container is made sufficiently flexible to enable easy dispensing, then the dispensing ease is improved, but the container cannot rebound back to its original shape after dispensing
Solution Approach 1:
The grooves segment the container wall structure, allowing controlled flexibility in specific regions while maintaining overall shape integrity. The segmented structure enables the container to be squeezed for dispensing while still having the capacity to rebound to its original shape after the dispensing action is completed.
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 solution enhances the container's elasticity and durability, ensuring efficient dispensing with minimal leakage and easy cleaning, even after repeated use, by allowing for improved spring-back and resistance to transient pressure increases.
Implementation Method 1
the container wall (11) is at least partially made from elastomer... the resiliently squeezable container... sufficient elastic spring-back to generate enough pressure to force air back through the bottom-dispensing orifice
Implementation Method 2
the container wall (11) comprises an interior surface (15) and an exterior surface (14), wherein the interior surface (15) comprises at least one circumferentially oriented groove (80)

AI summary
The need for a durable bottom dispensing package which is easy to dispense from, while having sufficient elasticity to return back to its original shape after dispensing, while also being easy to clean, and having reduced or no leakage during use, is met by making the container of the bottom dispensing package from an elastomer, and providing the interior surface of the container with at least one circumferentially oriented groove.
