Flexible Pouch with Longitudinal Flaps Prevents Rolling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current flexible cylindrical pouches are prone to rolling and instability when placed on their length, making them difficult to use effectively for storing and dispensing liquids without spilling.
Innovation Solution
A flexible pouch design featuring gusseted ends, a top seal, and outwardly projecting flaps that extend longitudinally to prevent rolling, along with an optional handle and ramped bottom panel to direct liquids towards the tap, providing stability and ease of use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the pouch is placed on its length to prevent knocking over, then stability against knocking is improved, but the pouch becomes prone to rolling
Solution Approach 1:
The pouch is divided into multiple functional segments: a cylindrical body for containment, flaps extending from the body for stability, and a tap assembly for dispensing. The flaps are segmented structures that project outwardly to prevent rolling while the body maintains its cylindrical form for liquid storage
Solution Approach 2:
The pouch employs asymmetric features including flaps of specific dimensions extending from the cylindrical body, creating an asymmetric profile that prevents rolling when placed on its length. The tap assembly is positioned asymmetrically at the bottom edge to optimize fluid dispensing while maintaining stability
2Ease of operation
If the pouch is made self-standing with vertical length extension, then ease of access to contents is improved, but the pouch becomes easy to knock over
Solution Approach 1:
The pouch transitions from a simple vertical cylinder to a three-dimensional structure with flaps extending laterally from the body. This dimensional addition creates a broader base of support while maintaining vertical accessibility, effectively adding stability without compromising ease of access to contents
3Stability of the object's composition
If flaps are added to prevent rolling, then stability is improved, but device complexity increases
Solution Approach 1:
The flaps are integrated directly into the pouch body as a continuous structure rather than separate components. The flap assembly is formed as one piece with the cylindrical body, eliminating the need for separate attachment mechanisms and reducing overall structural complexity while maintaining the rolling prevention function

AI summary
A flexible pouch having a pair of spaced apart flaps is provided. The flexible pouch includes a pouch body having a generally cylindrical shape. The flaps are disposed along the longitudinal length of the pouch body as to help prevent the pouch body from rolling over when laid on its length. The pouch may further include a fitment and an intermediate portion having a ramp shaped portion. The ramp shaped portion is opposite the fitment and slanted so as to direct fluids towards the fitment.
