Cosmetic Container Annular Body Leak Collection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Containers for liquid or gel cosmetic products face issues with leakage and product soiling due to non-drying properties of materials like nail varnish and gels, which do not solidify quickly and can continue to leak and dirty surfaces.
Innovation Solution
A container design featuring a receptacle with a closure element and an annular body that collects leaked product, using a snap coupling mechanism between the annular body and the receptacle to minimize leakage and prevent soiling, with an applicator assembly for product distribution.

Engineering Contradiction Analysis
1Object-affected harmful factors
If a conventional container design is used for liquid or gel cosmetic products, then the container structure is simple, but leakage occurs and causes product soiling due to non-drying properties
Solution Approach 1:
The container is segmented into distinct functional zones: an upper receptacle for holding the liquid or gel product, and a lower annular body for collecting leaks. This segmentation isolates the harmful leakage effect to a contained area, preventing it from soiling external surfaces while maintaining a relatively simple overall structure.
Solution Approach 2:
The annular body acts as an intermediary element between the receptacle and the external environment. It intercepts leaked product before it can reach external surfaces, serving as a protective barrier that prevents soiling without requiring complex sealing mechanisms or additional components.
2Adaptability or versatility
If materials like nail varnish and gels are used, then the product provides desired cosmetic effects, but it does not solidify quickly and continues to leak and dirty surfaces
Solution Approach 1:
The annular body is positioned beforehand to catch and contain any leakage that occurs during the product's extended drying period. This preemptive containment structure cushions against the harmful effects of prolonged liquid state, allowing the use of cosmetically effective but slowly drying materials without reliability concerns about soiling.
3Object-affected harmful factors
If an annular body is added to collect leaked product, then soiling is prevented, but the device complexity increases
Solution Approach 1:
The annular body is merged with the lower portion of the receptacle to form an integrated two-chamber structure. The upper chamber holds the product while the lower annular chamber collects leaks. This merging approach prevents surface contamination without requiring separate external collection devices or complex multi-component assemblies.
Solution Approach 2:
The solution moves the leakage containment function to a different spatial dimension by creating a vertical separation: the upper receptacle for product storage and the lower annular body for leak collection. This dimensional arrangement prevents horizontal spread of leaked product onto external surfaces while maintaining structural simplicity.

AI summary
A container includes a receptacle having a main portion in which a cavity is defined for containing a liquid or gel product, and a neck extending from the main portion and having an upper aperture which opens into the cavity. A closure element can be removably coupled with the receptacle to close the cavity at the aperture. An annular body can be fixed to the receptacle in such a way as to encircle the neck. When the annular body and the receptacle are mutually fixed, a gap is defined between the annular body and the neck which is configured to collect part of the product, such as product dropped from the brush, to be contained within the cavity and/or protruding through the aperture of the neck, thereby allowing the user to avoid getting dirty.
