Airless Cosmetic Pump With Brush Applicator and Sealed Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers face issues such as hermetic seal difficulties, contamination, loss of perfume or moisture, and uneven application due to cap-opened structures, deformation, and inefficient dispensing mechanisms, particularly with airless pumps that allow external air and impurities to enter, leading to pollution and deterioration of cosmetic contents.
Innovation Solution
An airless pumping type cosmetic container with a dual structure featuring a separate applicator and nozzle opening/closing unit that operates concurrently with the airless pump, transmitting power from a horizontal direction to a vertical direction to minimize dispensing passage length, ensuring airtightness and improved dispensing accuracy, and preventing external impurities from entering when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a cap-opened structure is used for cosmetic containers, then ease of operation is improved, but hermetic seal ability deteriorates and contamination increases
Solution Approach 1:
The container is divided into an inner container holding the cosmetic content and an outer container providing structural support. The inner container has a sealed opening that interfaces with the airless pump, while the outer container remains sealed. This segmentation allows the pump mechanism to access content without compromising the hermetic seal of the main container structure.
Solution Approach 2:
The airless pump acts as an intermediary device between the sealed container and the user. It provides a controlled dispensing mechanism that opens only a small valve or aperture temporarily, allowing precise content delivery while maintaining the hermetic seal of the main container. This mediator prevents direct exposure of the cosmetic content to external air and contaminants.
2Ease of operation
If a cap-opened structure is used for cosmetic containers, then ease of operation is improved, but pollution and deterioration of cosmetic content increases
Solution Approach 1:
The airless pump serves as a protective intermediary that controls the interface between the cosmetic content and the external environment. It uses a piston mechanism to push content through a sealed valve system, minimizing exposure to air and contaminants. The pump head creates a controlled dispensing pathway that prevents pollution and deterioration of the cosmetic formulation.
Solution Approach 2:
The container is designed to maintain an inert or controlled atmosphere around the cosmetic content. The airless pump mechanism operates within a sealed environment, and the dual-container structure protects the content from external air exposure. This creates a protective barrier that prevents oxidation and deterioration of the cosmetic formulation.
3Device complexity
If airless pump is used without separate applicator, then device complexity is reduced, but application uniformity and convenience deteriorates
Solution Approach 1:
The applicator is merged with the pump head assembly, forming an integrated application device. The applicator tip is positioned at the dispensing outlet of the airless pump, allowing seamless transition from pumping to application. This combination provides uniform application through the applicator's controlled contact surface while maintaining the space-efficient design of an integrated unit.
Solution Approach 2:
The pump head assembly serves multiple functions: it houses the airless pumping mechanism, contains the dispensing valve, and integrates the applicator tip for direct application. This multi-functional design eliminates the need for separate components, maintaining structural simplicity while enhancing application convenience and uniformity through the integrated applicator.
4Device complexity
If airless pump is used without separate applicator, then device complexity is reduced, but cosmetic waste increases
Solution Approach 1:
The applicator is integrated into the pump head, creating a direct and controlled delivery system. This merging eliminates the need for separate application tools that could retain residue, ensuring complete dispensing of the cosmetic content. The integrated design allows precise control over the dispensing amount, minimizing waste while maintaining structural simplicity.

AI summary
An airless pump includes a storage unit having inner and outer shells. A head is fastened to the storage unit, wherein the head has a fastening groove and a nozzle. An application unit has the form of a brush and is fastened into the fastening groove so as to allow the content to be applied onto the skin. An airless pump is provided inside the head and connects the storage unit and the nozzle. The airless pump converts the direction of power that has been produced when an operation button is pushed, from the horizontal direction to the vertical direction in order to pump the content from the inner shell. A nozzle opening/closing unit is disposed between the airless pump and the nozzle in order to open/close the nozzle in the same stroke as an operation of the airless pump.
