Ventilated Lid Flutes for Humidity-Resistant Detergent Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Corrugated fiberboard containers used for detergent products, especially water soluble unit dose articles, are prone to damage and deterioration in humid environments, leading to potential leakage and contamination, and are not as environmentally friendly as desired.
Innovation Solution
A specific lid structure with flutes that channel airflow to ventilate the corrugated fiberboard, preventing humidity retention and exposure to external humidity, while allowing for the display of information and easy identification of the material used, thus enhancing the durability and environmental friendliness of the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If corrugated fiberboard containers are used for detergent products, then environmental friendliness is improved, but resistance to humidity and structural integrity deteriorate
Solution Approach 1:
The lid is segmented into multiple functional layers: an outer corrugated fiberboard layer for environmental friendliness, an inner plastic resin layer for humidity resistance, and a sealing layer for leakage prevention. This segmentation allows each material to perform its optimal function while working together as a unified structure.
Solution Approach 2:
The container employs composite material construction, combining corrugated fiberboard with plastic resin layers. This composite structure integrates the environmental benefits of fiberboard with the moisture-resistant properties of plastic, resolving the contradiction between eco-friendliness and humidity resistance.
2Object-affected harmful factors
If corrugated fiberboard containers are used, then recyclability is improved, but susceptibility to damage in humid environments worsens
Solution Approach 1:
The container structure is divided into separate layers with distinct functions: the outer corrugated fiberboard layer maintains recyclability and structural form, while the inner plastic resin layer provides damage resistance in humid conditions. This segmentation allows the fiberboard to be recycled while the plastic layer protects against environmental damage.
Solution Approach 2:
The plastic resin layer acts as a protective barrier that cushions the corrugated fiberboard from humidity damage before the fiberboard is exposed to humid environments. This beforehand protection prevents structural deterioration and maintains strength throughout the product lifecycle.
3Object-affected harmful factors
If sealed container structure is used, then protection from external humidity is improved, but ventilation and aeration worsen
Solution Approach 1:
The container incorporates porous or permeable structures in specific areas that allow controlled ventilation while maintaining overall protection from external humidity. The porous design enables aeration without compromising the sealed protection provided by the plastic resin layers.
Solution Approach 2:
Different regions of the container have different structural qualities: areas requiring protection from external humidity have sealed plastic resin layers, while areas requiring ventilation have porous or open structures. This local differentiation of quality allows both protection and ventilation functions to coexist.
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 ventilated lid structure effectively maintains the integrity of the corrugated fiberboard, reducing the risk of deterioration and leakage, while promoting the use of environmentally friendly materials by ensuring the container remains dry and secure, even in humid conditions.
Implementation Method 1
specific flutes of corrugated fiberboard are forming a channel in communication with an external environment outside of the lid, such that these flutes may channel an air flow which contributes to aerating the flutes
