Airless Pump Perpendicular Actuation for Hermetic Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional cosmetic containers face issues with hermetic sealing, contamination from air and impurities, uneven dispensing, and deformation due to their design, which leads to waste and deterioration of cosmetic products.
Innovation Solution
An airless pump system is integrated into a dual-structured cosmetic container where the operation button's power is converted to operate perpendicular to its push direction, allowing for efficient upward and downward pumping, with a nozzle that opens and closes concurrently to prevent external contamination and ensure accurate dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a cap is used to open/close the container opening, then the container structure is simple, but hermetic sealing is difficult and external air/impurities easily enter
Solution Approach 1:
The pump mechanism incorporates movable components including a piston that moves within a cylinder, and a nozzle that can open and close dynamically. This dynamic structure enables hermetic sealing while maintaining operational simplicity, as the moving parts create sealed chambers during pumping action without requiring complex static sealing mechanisms.
Solution Approach 2:
The system changes the operational state of the nozzle from closed to open position during pump operation. This parameter change enables controlled dispensing while maintaining hermetic sealing when closed, resolving the contradiction between simple structure and reliable sealing.
2Ease of operation
If the container is opened using a cap for content dispensing, then ease of operation is improved, but external air and impurities enter causing pollution and deterioration
Solution Approach 1:
The harmful factor of air and impurity entry is eliminated by removing the cap-opening mechanism and replacing it with a hermetic pump system. The pump dispenses content through a controlled nozzle opening without requiring container opening, thus extracting the contamination problem from the system while maintaining ease of operation.
Solution Approach 2:
The nozzle acts as an intermediary between the sealed container interior and the external environment. It provides a controlled passage for content dispensing while maintaining hermetic sealing, mediating between the need for content access and the need to prevent contamination.
3Ease of operation
If a wide opening is used for finger scooping, then ease of operation is improved, but cosmetic waste increases and essential components are lost
Solution Approach 1:
The manual finger scooping mechanical action is replaced with a pump mechanism that provides controlled dispensing. This substitution eliminates the inability to control dispensing amount while maintaining ease of operation, as the pump delivers precise portions without requiring finger insertion into the container.
4Productivity
If tubular container structure is used for content dispensing, then productivity is improved, but external shape deformation occurs reducing preservation ability
Solution Approach 1:
The container is segmented into distinct functional components: a rigid outer container for shape stability, an inner chamber for content storage, and a separate pump mechanism for dispensing. This segmentation allows the outer container to maintain its shape for preservation while the pump provides efficient content dispensing without deforming the overall structure.

AI summary
An airless pump and a cosmetic container including the same. The airless pump includes a nozzle of a head and a compression cylinder disposed between the storage container and the nozzle. A sealing cap fixes the compression cylinder. A piston valve and a piston are fastened into an inner compression chamber inside the compression cylinder. An operation pipe is disposed above the sealing cap in a direction perpendicular to the direction in which an operation button is pushed. The operation pipe is actuated and drives the piston and piston valve in the perpendicular direction. A spring is disposed between the operation pipe and the sealing cap. A slider axially is axially coupled to the operation pipe in the perpendicular direction. The slider is actuated by the operation button to horizontally reciprocate in a direction, thereby driving the operation pipe in the perpendicular direction.
