Foam Discharge Container with Pushing Portion for One-Hand Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foam discharge containers require a two-hand operation to dispense foam, which is inconvenient and inefficient, and also struggle with dispensing liquid agents effectively as liquids rather than foams.
Innovation Solution
A foam discharge container design featuring a foam discharge cap and head with a pushing portion that maintains a constant distance between the discharge port and the target body, allowing for one-hand operation by using a pushing mechanism to discharge foam or liquid agents, incorporating a foamer mechanism to mix liquid agents with air and create foam.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional foam discharge container uses multiple discrete discharge ports arranged in specific patterns, then foam can be discharged in molded shapes, but the device requires two-hand operation and cannot easily dispense liquid agents
Solution Approach 1:
The discharge port is divided into multiple independent nozzles (first discharge nozzle and second discharge nozzle) with different structures. The first discharge nozzle has a larger diameter for liquid agent discharge, while the second discharge nozzle has a smaller diameter for foam discharge. This segmentation allows the single discharge port to perform multiple functions, enabling one-hand operation while maintaining the capability to dispense both liquid agents and foamed products.
2Productivity
If the discharge port is designed for molded foam discharge with multiple small ports, then foam shaping is achieved, but liquid agent discharge efficiency is reduced
Solution Approach 1:
Different regions of the discharge port are given different properties: the first discharge nozzle has a larger diameter and is positioned to discharge liquid agents efficiently, while the second discharge nozzle has a smaller diameter and is positioned to create molded foam shapes. This local differentiation of discharge port characteristics allows simultaneous optimization of both liquid agent discharge efficiency and foam shape accuracy without compromise.
3Ease of operation
If the discharge port is positioned close to the target body for one-hand operation, then ease of use is improved, but foam shape formation and liquid agent control become difficult
Solution Approach 1:
The discharge port is designed with movable components including a piston that can move within the container body. This dynamic structure allows the discharge port to adjust its position and opening degree during operation, enabling precise control of discharge amount and timing even when positioned close to the target body for one-hand operation. The movable piston provides dynamic adjustment capability that maintains discharge control precision while achieving operational convenience.

Function Achieved in This Case
Enables convenient one-hand operation for receiving foam on a target body and allows for precise shaping of foam into intended shapes, while also facilitating the discharge of liquid agents as needed, enhancing usability and efficiency.
Implementation Method 1
containers (foam discharge containers) in which various liquid materials (liquid agents) such as hand soap, facial cleanser, dishwashing detergent, and hair dressing agent are mixed with air to be foamed

AI summary
A foam discharge container (100) is a foam discharge container (100) for discharging foam in response to a pushing operation, and includes a discharge port which is opened in a direction opposite to a pushing direction of the pushing operation and discharges foam, and a pushing portion (85) that keeps the distance between a discharge target body (40) receiving foam and the discharge port constant.
