Water-Soluble Unit Dose Container with Paper Interior and Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Water-soluble unit dose articles are prone to structural failure and leakage due to extreme temperature variations during transport and storage, leading to contamination and inconvenience. Additionally, containers may accidentally open, exposing the articles to further environmental stress and contamination.
Innovation Solution
A consumer product featuring a container with a paper-based interior surface that directly contacts the water-soluble film of the unit dose articles, along with a locking mechanism to prevent accidental opening, thereby minimizing exposure to temperature variations and contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If water-soluble unit dose articles are stored in rigid or flexible plastic containers, then they can be transported and stored conveniently, but extreme temperature variations cause structural failure and leakage of the articles
Solution Approach 1:
A paper-based interior surface is introduced as an intermediary between the water-soluble unit dose articles and the container environment. This paper-based surface acts as a protective mediator that reduces the impact of extreme temperature variations on the articles, preventing structural failure while maintaining the convenience of container storage.
2Reliability
If containers are made secure with locking mechanisms to prevent accidental opening, then premature exposure to environmental conditions is prevented, but the device complexity increases
Solution Approach 1:
The locking mechanism is extracted as a separate functional component from the main container structure. This allows the locking function to be implemented independently, providing protection against accidental opening while minimizing the impact on overall container complexity and design.
3Quantity of substance
If multiple water-soluble unit dose articles are stored together in a container, then storage efficiency is improved, but temperature variations and accidental opening cause contamination between articles
Solution Approach 1:
The paper-based interior surface serves as a protective intermediary layer that surrounds and protects multiple unit dose articles from harmful temperature variations and prevents contamination between them, allowing efficient storage of multiple articles without compromising their integrity.
Solution Approach 2:
The locking mechanism provides preliminary protection by preventing accidental opening of the container before contamination can occur. This anticipatory measure ensures that articles remain sealed and protected from environmental factors throughout storage.
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 use of a paper-based interior surface in the container reduces the incidence of structural failure and leakage of the unit dose articles, while the locking mechanism ensures that the container remains closed during transport and storage, maintaining the integrity and convenience of the product.
Implementation Method 1
the water-soluble film of the at least one unit dose article directly contacts the paper-based material of the internal surface
