Dome-Shaped Refill Cover for Cosmetic Compacts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic material compact containers with flat refill container covers swell due to evaporation, leading to increased material loss and manufacturing costs due to the need for hinge pins in coupling mechanisms.
Innovation Solution
A dome-shaped refill container cover with a sealing protrusion at the bottom end and a stopper protrusion on the hinge-coupling part, eliminating the need for a hinge pin and reducing swelling, thereby minimizing material evaporation and manufacturing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a flat refill container cover is used, then the manufacturing cost and assembly complexity are lower, but the cover swells due to evaporation of cosmetic material, increasing material loss
Solution Approach 1:
The refill container cover is designed with a dome-shaped curved surface instead of a flat surface. This curvature provides internal volume to accommodate expansion from cosmetic material evaporation, preventing the cover from swelling outward and maintaining sealing effectiveness, thereby reducing material loss.
2Reliability
If a hinge pin is used to couple the refill container cover to the refill container, then the coupling is secure, but the number of parts increases and manufacturing cost rises
Solution Approach 1:
The hinge-coupling mechanism is integrated directly into the refill container cover structure, merging the hinge function with the cover body. This eliminates the need for separate hinge pins and reduction gears, reducing the number of parts while maintaining secure coupling between the cover and container.

AI summary
The present invention relates to a cosmetic material compact container provided with a dome-shaped refill container cover, and more specifically, to a cosmetic material compact container provided with a dome-shaped refill container cover structured so that the refill container cover is coupled to a refill container, wherein the refill container cover has a dome shape which bulges upward so that the refill container cover does not swell even when the cosmetic material accommodated in the refill container evaporates, so as to minimize the amount of cosmetic material evaporation. Also, a sealing protrusion is provided in all directions at the bottom end of the of the refill container cover to effectively seal a cosmetic material accommodating space in the refill container, thereby allowing the cosmetic material to function effectively for a long time. In addition, a stopper protrusion is formed on a hinge-coupling part on the refill container cover and a stopper hook is formed on a hinge-coupling part on the refill container, when the refill container cover is connected to the refill container, so that easy fixing and coupling is enabled without requiring connection by a hinge pin, thereby reducing the number of parts, and in turn, reducing manufacturing cost and man hours, and ultimately improving production quantity.
