Foam Dispensing Container Outlet Geometry for Complex Shape Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foam dispensing containers struggle to create finely-profiled foam objects with intended shapes, as they can only produce simple shapes due to limited outlet geometries, making it difficult to build complex designs.
Innovation Solution
A foam dispensing container with a nozzle having an outlet with a contiguous geometry narrowed from the intended shape, allowing for the dispensing of a predetermined amount of foamy liquid agent that builds up into the intended shape through a combination of linear and widely-opened parts, enabling the creation of complex shapes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If outlets are arranged discretely at multiple points with simple geometry, then foam dispensing is achieved, but only simple foam shapes can be built up
Solution Approach 1:
The outlet is divided into multiple regions (first region with first geometry and second region with second geometry) that correspond to different parts of the intended foam shape. Each region dispenses foam to a specific location, allowing complex shapes to be built up by combining multiple simple foam lumps in a controlled manner.
Solution Approach 2:
Different regions of the outlet are assigned different geometries (first geometry vs. second geometry) to create different foam characteristics in different locations. This local differentiation enables precise control over the overall foam shape while maintaining simple dispensing operation.
2Ease of operation
If a single round open nozzle is used, then dispensing operation is simple, but foam shape control is limited
Solution Approach 1:
The single nozzle is segmented into multiple regions with different geometries. Each region maintains simplicity for easy operation, while the combination of regions produces complex foam shapes. This segmentation allows the nozzle to function both as a simple dispenser and a precision shaping tool.
Solution Approach 2:
The outlet geometry transitions from a simple round opening to a multi-regional configuration that adds spatial dimensionality. By arranging different geometric regions in specific spatial relationships, complex two-dimensional foam shapes are achieved while maintaining operational simplicity.
3Ease of operation
If outlets are designed for simple foam lumps, then dispensing is easy, but finely-profiled foam objects cannot be built up
Solution Approach 1:
The outlet incorporates regions with different geometries (first region with first geometry, second region with second geometry) that create locally different foam characteristics. This local quality differentiation enables precise control over the overall foam profile while maintaining easy dispensing operation through a single integrated nozzle.
Solution Approach 2:
Multiple regions with different geometries are merged into a single outlet structure. The combined effect of these regions produces finely-profiled foam objects with complex shapes, while the integrated design maintains ease of operation comparable to simple nozzles.

AI summary
A foam dispensing container (100) has a container body (40) that reserves a liquid agent (L); a head part (30) that has an outlet (20), and dispenses the liquid agent (L) delivered from the container body (40) through the outlet (20) into foam; and a pump head part (32) that allows dispensing of a predetermined amount of the foamy liquid agent (foam) through the outlet (20) each time it accepts a user's operation. The outlet (20) is formed with a contiguous geometry narrowed from an intended shape. A foam, dispensed through the outlet (20) as a result of a single or multiple operations of the pump head part (32), is built up into the intended shape in a plan view seen in the dispensing direction.
