Pouring Spout with Flared Section for Scent Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for home care liquids with integrated pouring spouts minimize the exposed surface area of the liquid, which limits the release of scent during dispensing, making them suboptimal for scented household products.
Innovation Solution
A container design with a pouring spout that increases the exposed surface area by incorporating a flared section and topographical features such as protuberances or depressions on the floor and side surfaces, altering fluid dynamics to enhance fragrance release.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the pouring spout is designed to minimize the exposed surface area of the liquid, then the liquid flow is concentrated and controlled, but the amount of scent released during dispensing is reduced
Solution Approach 1:
The pouring spout incorporates a flared section that expands the flow channel in the transverse dimension, allowing the liquid to spread out laterally while maintaining controlled flow. This dimensional expansion increases the exposed surface area of the liquid without compromising flow control, thereby resolving the contradiction between concentrated flow and enhanced scent release.
Solution Approach 2:
The pouring spout features localized topographical variations including protuberances and depressions on the inner surfaces of the flow channel. These local structural modifications create turbulence and increase the liquid's exposed surface area at specific locations, enhancing scent release while maintaining overall flow control through the spout's general geometry.
2Productivity
If the pouring spout has a narrow flow channel, then the liquid dispensing is controlled and precise, but the exposed surface area of the liquid is minimized
Solution Approach 1:
The pouring spout transitions from a narrower upstream section to a flared downstream section, creating a dynamic flow channel that adapts its cross-sectional area along the flow path. This dynamic geometry allows the liquid to be precisely controlled during initial flow while expanding in the flared section to increase exposed surface area for enhanced scent release.
Solution Approach 2:
The pouring spout is divided into distinct functional sections: an upstream section for flow control, a flared section for surface area expansion, and downstream sections with topographical features for turbulence generation. This segmentation allows each section to optimize its specific function, achieving both dispensing control and enhanced scent release.
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 design significantly increases the amount of scent released during dispensing by spreading the liquid and increasing the surface area exposed, providing a more effective fragrance release mechanism.
Implementation Method 1
the flow channel comprises a flared section having a transverse width that increases with longitudinal distance from the spout inlet, allowing the flow of the scented household liquid to transversely spread out to increase the exposed surface area
Implementation Method 2
at least one of the floor surface and side surfaces that define the flow channel have a topographical feature that may increase the exposed surface area of a liquid in the pouring spout and/or alter the fluid dynamics of the liquid in the pouring spout during dispensing

AI summary
A packaged product comprising a container (100) and a scented household liquid is disclosed that comprises an integrated pouring spout (130) that is configured to increase the exposed surface area of a scented household liquid during a product dispensing event, thereby increasing the amount of scent (or fragrance) released from the scented household liquid during the product dispensing event. In one aspect, the pouring spout may have a flared section in which the width of the flow channel (147) increases moving toward the spout outlet.
