Reusable Container With Nested Spouted Pouch for Controlled Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging for pouched liquid cleaning products, such as spouted pouches, face challenges in accurately dispensing measured doses, especially as they become empty, due to their unwieldy nature and fluidity, making controlled pouring difficult for consumers who need to dispense small amounts repeatedly.
Innovation Solution
A re-usable dispensing system comprising a rigid container with a pouch chamber and pour spout, combined with a flexible spouted pouch, featuring a dosing device nested in a handle aperture and engagement members for fluid communication, allowing for accurate and controlled dispensing of cleaning liquids.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If a flexible spouted pouch is used for packaging cleaning liquid, then material usage is reduced and environmental impact is lowered, but controlled dispensing becomes difficult especially as the pouch becomes empty
Solution Approach 1:
A rigid container serves as an intermediary device between the flexible pouch and the dispensing point. The pouch is placed inside the rigid container, which provides structural support and enables controlled pouring through its integrated handle and spout design, allowing accurate dispensing even when the pouch is nearly empty
Solution Approach 2:
The flexible pouch is nested within the rigid container, with the pouch body contained inside the container's pouch chamber. This nested arrangement allows the rigid container to provide structural support while the pouch remains replaceable and environmentally friendly
2Ease of operation
If a rigid container is used for dispensing cleaning liquid, then controlled pouring is achieved, but material usage increases and environmental impact rises
Solution Approach 1:
The dispensing system is segmented into two distinct parts: a reusable rigid container that provides controlled dispensing functionality, and a replaceable flexible pouch that contains the cleaning liquid. This segmentation allows the rigid container to be used repeatedly while the pouch is replaced, reducing overall material usage compared to completely rigid packaging
Solution Approach 2:
The flexible pouch is designed to be discarded after use and replaced, while the rigid container is recovered and reused. This approach reduces material consumption by eliminating the need for a new rigid container each time, while still achieving controlled pouring through the retained rigid container
3Loss of substance
If a flexible pouch is used without a rigid container, then material usage is minimized, but accurate measured dispensing cannot be achieved
Solution Approach 1:
The rigid container acts as a mediator that enables accurate measured dispensing. It includes a handle aperture that can accommodate dosing devices and a spout designed for controlled pouring, allowing users to dispense accurate measured doses while still using the environmentally friendly flexible pouch for storage
