Cosmetic Pot Pressurizing System for Air-Free Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic pots expose cream to air during use, risking contamination and requiring large diameters for easy dispensing, which is not practical.
Innovation Solution
A cosmetic pot design featuring a base with a press bottom, a variable volume container, and a pressurizing system that compresses the container against the press bottom, allowing for easy and controlled dispensing through a product dispenser with an elastic return mechanism, avoiding direct contact with air and enabling precise dose delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pump or dosing device is added to protect the cream, then the sealing and protection are improved, but the device complexity increases
Solution Approach 1:
The patent extracts the dosing function from a complex pump mechanism and integrates it directly into the container structure itself. The container wall becomes the dosing element, with a simple opening mechanism that allows cream to be dispensed in controlled amounts without requiring separate pumping components.
Solution Approach 2:
The patent merges the container and dosing device into a single integrated structure. The container wall serves dual purposes: containing the cream and providing the dosing function through a simple opening mechanism, eliminating the need for separate pump components.
2Ease of operation
If the pot diameter is made large to allow easy pressing of the plate, then the ease of operation is improved, but the aesthetic appearance and space efficiency deteriorate
Solution Approach 1:
The patent applies local quality by concentrating the pressing action on a specific localized area (the opening mechanism) rather than requiring the user to press the entire container bottom. This allows for a compact overall shape while maintaining ease of operation through a focused interaction point.
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 effectively preserves the product by minimizing air exposure and allows for easy, natural dispensing of desired product doses without the need for a pump, accommodating various pot dimensions and ensuring consistent dispensing throughout the product's life.
Implementation Method 1
an elastic return member configured to act on the dispensing head to close the stopper
Implementation Method 2
A pressurizing system of the container configured for compressing the container against the press bottom
