Refillable Nail Polish Container with Volume-Regulating Valve
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional nail polish containers are complex to assemble and refill, leading to inefficient use of cosmetic liquid, staining issues, and environmental concerns due to non-reusable designs.
Innovation Solution
A detachable nail polish container system comprising a refill container and an outer barrel with a volume-regulating valve, allowing for easy refilling and controlled dispensing of nail polish through a stepwise operation, simplifying manufacturing and assembly while enabling reuse.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If a conventional fixed-amount dispensing nail polish applicator is used, then the nail polish dispensing amount is controlled, but the construction becomes very complicated making manufacturing and assembling difficult
Solution Approach 1:
The nail polish container is divided into separate components: an outer barrel and an inner refill container. The refill container can be independently removed and refilled, simplifying the overall structure while maintaining controlled dispensing through a valve mechanism in the outer barrel.
Solution Approach 2:
The refillable inner container is extracted as a separate removable component from the outer barrel. This allows the complex dispensing control to be located in the simpler outer barrel while the inner container remains a simple storage vessel that can be easily refilled.
2Device complexity
If a conventional threaded cap container is used, then the structure is simple, but the application stick carries excessive nail polish requiring scraping and causes staining
Solution Approach 1:
A valve mechanism acts as an intermediary between the nail polish reservoir and the application brush. This valve controls the flow of nail polish to the brush, ensuring only the required amount is dispensed and preventing excessive polish from staining the application stick or surrounding areas.
3Device complexity
If a conventional non-refillable container is used, then the structure is simple, but refill for reuse is impossible causing increased manufacturing costs and environmental concerns
Solution Approach 1:
The container is segmented into a permanent outer barrel containing the dispensing mechanism and a removable inner refill container. This segmentation allows the outer barrel to remain simple while the inner container provides refillability, enabling reuse and reducing waste.
Solution Approach 2:
The inner refill container is designed to be removable and refillable, allowing users to recover and reuse the container after the nail polish is depleted. This reduces manufacturing waste and environmental impact while maintaining a simple overall structure.

AI summary
A nail polish container includes an outer barrel having a dispense nozzle and a detachable refill container. The dispense nozzle includes a brush and a dispense tube seat mounted therein. The refill container contains therein a liquid content and has a top mouth receiving therein a volume-regulating valve seat and a tubular sleeve. When the refill container is fit into the outer barrel, a dispense tube of the dispense tube seat is inserted into the valve seat, whereby depression of the refill container may cause the valve to open to allow the nail polish contained in the refill container to flow, in a volume-regulated manner, to the brush for performing application of the nail polish.
