Refillable Cosmetic Container With Separable Pot and Vessel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic containers, particularly those made of glass, are not environmentally friendly due to the difficulty in separating the internal vessel from the pot, leading to improper waste disposal and the need for entire container disposal upon substance depletion.
Innovation Solution
A container design featuring a vessel that can be partially housed within a pot, with a coupling mechanism allowing easy separation and reusability, enabling the pot and vessel to be disposed of separately and facilitating refilling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the internal vessel is firmly fastened to the pot mouth, then the container structure is stable and secure, but the vessel cannot be separated from the pot for waste sorting
Solution Approach 1:
The container is divided into two separable parts: the pot and the internal vessel. The coupling mechanism includes a threaded connection that allows the vessel to be securely fastened during use but easily unscrewed for separation. This segmentation enables both stable containment during use and easy separation for waste sorting, resolving the contradiction between structural stability and ease of separation.
2Ease of manufacture
If the entire container is disposed of after substance depletion, then waste disposal is simple, but environmental waste increases and resources are not conserved
Solution Approach 1:
The design enables selective discarding and recovering of container components. The internal vessel containing the cosmetic substance can be removed and disposed of or refilled separately from the pot. This allows the pot to be reused or recycled while the vessel is properly disposed of, reducing overall waste and enabling resource conservation through partial recovery and reuse.
3Shape
If glass pots are used, then aesthetic appearance and product protection are improved, but waste sorting becomes impossible due to inability to separate components
Solution Approach 1:
The container is designed with separable glass pot and plastic vessel components connected by a threaded coupling mechanism. This segmentation maintains the aesthetic and protective benefits of the glass pot while enabling easy separation for proper waste sorting. The vessel can be unscrewed from the pot, allowing each material to be disposed of in appropriate recycling streams, thus resolving the contradiction between aesthetic appearance and waste sorting capability.

AI summary
A container for a cosmetic product includes a pot and a lid, there being mutual coupling means between the pot and the lid, and a vessel positioned at least partially inside the pot, the container being made of plastic material, the pot having, at a mouth thereof, at least one tooth protruding laterally with respect to the mouth, the vessel including a flange resting on a free end of the mouth of the container, there extending from the said flange, in an essentially perpendicular direction with respect thereto, at least one skirt which is equipped with at least one counter-tooth which engages, in an undercut manner, with the said at least one tooth, the skirt being interrupted in at least one portion along the perimeter in order to expose at least part of the flange.
