Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional flexible container dispensing systems with rigid outer enclosures are inefficient in reducing raw material and shipping costs, improving recyclability, and minimizing waste and disposal costs, while also failing to deliver fluid compositions under pressure without propellants.
Innovation Solution
A flexible container with a spray valve and a propellant-free pressurized dispensing system, utilizing a sleeve and bag-on-valve assembly (SBoV) integrated into a multilayer film structure, where the SBoV includes a valve, valve seat, and an elastic sleeve, allowing for the delivery of fluid compositions under pressure without the need for propellants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid outer enclosure is used in conventional BoV dispensing systems, then structural strength and valve protection are improved, but material costs, shipping costs, and disposal costs increase while recyclability decreases
Solution Approach 1:
The patent replaces the rigid outer enclosure with a flexible container made from laminated film layers that provides the necessary structural strength while being lightweight, cost-effective, and recyclable. The flexible container maintains the integrity of the BoV dispensing system without requiring rigid plastic or metal construction.
Solution Approach 2:
The flexible container utilizes composite laminated film structures combining multiple layers with different properties (barrier, strength, sealability) to achieve the required structural performance without the need for rigid materials. This composite approach allows the flexible container to protect the valve and maintain strength while reducing cost and improving sustainability.
2Reliability
If a rigid outer enclosure is used, then valve protection is improved, but recyclability and waste reduction are worsened
Solution Approach 1:
The flexible container serves as an protective enclosure for the valve mechanism while being made from recyclable laminated films. This replaces rigid enclosures that are difficult to recycle, thereby reducing waste volume and improving environmental sustainability without compromising valve protection.
Solution Approach 2:
The flexible container is designed to be recyclable after product depletion, allowing the material to be recovered and reused. This contrasts with rigid enclosures that typically end up in landfills, thereby reducing harmful waste factors while maintaining reliable valve protection during use.
3Ease of operation
If conventional BoV systems are used with rigid enclosures, then dispensing functionality is achieved, but propellant-free pressurized spray delivery is not possible
Solution Approach 1:
The patent modifies the physical parameters of the container system by using a flexible container that can deform under elastic force, enabling the propellant-free pressurized spray delivery mechanism to function. The flexibility allows the container to compress and expand, creating the necessary pressure changes for spray dispensing without requiring propellants.
Solution Approach 2:
The system utilizes elastic force generated by the flexible container's deformation to create pressurized fluid flow for spray delivery. The elastic sleeve compresses the fluid composition within the flexible container, generating the pressure needed for spray dispensing through the valve without requiring chemical propellants.
4Ease of manufacture
If rigid plastic or metal enclosures are used, then manufacturing and assembly are simplified, but shipping costs and disposal costs increase
Solution Approach 1:
The flexible container made from laminated films is significantly lighter than rigid plastic or metal enclosures while providing adequate protection for the dispensing system. This weight reduction lowers shipping costs and improves handling efficiency without compromising the ability to assemble and manufacture the dispensing system.
