Cosmetic Container With Rotating Blade Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers with high viscosity cosmetics face issues such as difficulty in discharging the cosmetic, risk of foreign matter entry, incomplete mixing, and cosmetic residue on the inner walls, especially when using dip tubes or rotating blades, which limits their functionality and design appeal.
Innovation Solution
A cosmetic container design featuring a storing unit, a discharging unit with a pump and tube, and a fluid supporting unit that includes a concave surface for fluid collection, a rotating blade unit for mixing, and a check valve to prevent backflow, allowing for efficient discharge and mixing without external containers, while preventing residue on the inner walls.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a dip tube type pump is applied to store high viscosity cosmetic, then the cosmetic can be stored in the container, but the cosmetic is difficult to flow into the dip tube and remains attached to the inner wall, causing incomplete discharge
Solution Approach 1:
The patent employs a rotating blade assembly that rotates to dynamically agitate the cosmetic product. This rotation creates centrifugal force and shear stress that mobilizes the high viscosity cosmetic, preventing it from remaining stationary and attached to the inner wall, thereby enabling complete discharge through the dip tube pump mechanism
Solution Approach 2:
The rotating blade performs preliminary agitation of the cosmetic before discharge. By pre-mixing and mobilizing the cosmetic product through rotation, the system ensures that the cosmetic is properly positioned and fluidized to flow into the dip tube, preventing attachment to the inner wall surface
2Adaptability or versatility
If a rotating blade is fixed to a rotational axle at the center of the container, then the blade can mix the cosmetic, but it becomes difficult to employ a pump and dip tube extending to or near the bottom of the container
Solution Approach 1:
The patent nests the rotating blade assembly within the dip tube structure. The blade rotates within the confines of the dip tube, allowing the pump mechanism to be integrated with the mixing function. This nested arrangement eliminates the need for a separate central axle that would interfere with dip tube placement, enabling both pumping and mixing functions to coexist in the same vertical space
3Productivity
If agitating blades are spaced apart in an up and down direction, then the structure is simpler, but cosmetic in certain regions is not collided with the blades and remains indirectly agitated, reducing mixing efficiency
Solution Approach 1:
The patent positions the rotating blade to extend along the entire length of the dip tube, creating different agitation zones at different heights. The blade configuration provides intensive local agitation where cosmetic contacts the blade while also creating overall circulation patterns that indirectly agitate cosmetic in other regions, achieving comprehensive mixing throughout the container volume

Function Achieved in This Case
Enables easy and complete discharge of high viscosity cosmetics, reduces the risk of foreign matter entry, ensures thorough mixing, and maintains a clean inner surface, enhancing user convenience and product appeal.
Implementation Method 1
a pumping part which supports the fluid supporting unit and generates pressure for pumping the fluid stored in the storing unit
Implementation Method 2
a check valve which is coupled to one side of the fluid supporting unit so as to prevent the fluid discharged to the outside from flowing backward to the storing unit
