Refillable Cosmetic Container with Recessed Lid and Gripping System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic product containers have issues with size, practicality, and sealing, making them unsuitable for on-the-go use and refilling, with a cap that is too large and not easily refillable.
Innovation Solution
A refillable container design featuring a base with a peripheral wall, a pan for the product, an insert with a side wall and peripheral edge, and a lid that moves between open and closed positions, incorporating an opening/closing system and a pan gripping system for easy removal and refilling, ensuring a tight fit and optimal product preservation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional cap with opening/closing system is used, then the container can be closed to preserve product, but the cap size becomes too great and is not suitable for on-the-go use
Solution Approach 1:
The container is divided into distinct functional components: a base with receiving space, a removable pan for the cosmetic product, and a lid with opening/closing system. This segmentation allows the lid mechanism to be optimized independently for compactness while maintaining its sealing function, and the pan can be separately removed for refilling without requiring a large cap structure.
2Volume of moving object
If the cap is designed to be compact, then it is suitable for on-the-go use, but the opening/closing system becomes difficult to integrate and sealing is compromised
Solution Approach 1:
The pan is nested within the base's receiving space, and the lid is designed to close over both the base and pan assembly. The opening/closing system is integrated into the lid structure in a space-efficient manner, allowing the compact overall form while maintaining full functionality. The nested arrangement allows components to be tightly packed without interfering with each other's operation.
3Quantity of substance
If the pan is tightly fitted in the insert, then product capacity is optimized, but the pan becomes difficult to remove for refilling
Solution Approach 1:
A gripping system acts as an intermediary mechanism between the user and the tightly fitted pan. This gripping system provides access points or engagement features that allow the user to easily grasp and remove the pan from the receiving space, overcoming the tight fit that optimizes product capacity. The gripping system mediates between the need for secure containment and easy removal.
4Reliability
If the lid is designed to fully close the opening, then sealing is improved, but the opening/closing system size increases
Solution Approach 1:
The sealing function is concentrated at the specific location where the lid contacts the base and pan, rather than requiring a large overall lid structure. The lid is designed with localized sealing surfaces or gaskets at the closure interface, allowing effective sealing with a compact lid mechanism. The opening/closing system is sized appropriately for the actual sealing requirement rather than oversizing the entire lid assembly.

AI summary
The container for cosmetic product, refillable and suitable for use on the go, includes a base housing a fixed interior wall arrangement in which is embedded a removable pan containing the product. An upper opening of the wall arrangement is delimited by a peripheral edge which rises from a partitioning side wall to a peripheral wall of the base. The flat lid of the container, hermetically covering this opening, is kept closed, for example when an associated perpendicular rod passing axially through the edge is in the position of maximum insertion. Inside the base, a complementary cavity adjacent to the compartment receiving the pan forms and/or houses a gripping system, making a side wall of the pan accessible, which allows selective extraction of the pan via the top when the lid is in the open position. The container may form a child receptacle embedded in the cap of a parent receptacle.
