Cosmetic Packaging with Deformable Release Body and Scraper
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging for liquid cosmetic products makes it difficult to use the product evenly as it is depleted, leading to waste, leakage, and drying out due to exposure to air, with complicated operations required to access the remaining product and issues with applicator saturation and cleaning.
Innovation Solution
A packaging design featuring a receptacle, lid, applicator, and a deformable containment and release body impregnated with the cosmetic product, which moves between raised and lowered positions to ensure efficient product withdrawal and application, minimizing waste and leakage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the applicator is immersed in the liquid cosmetic product to withdraw product, then the applicator can be impregnated with the cosmetic product, but when the product is depleted it becomes difficult to spread evenly on the applicator and part of the applicator does not get covered
Solution Approach 1:
A scraper element is introduced as an intermediary component between the applicator and the receptacle bottom. This scraper actively removes accumulated cosmetic product from the rod and receptacle surfaces, ensuring the applicator can be evenly re-impregnated even when product levels are low, thus maintaining ease of operation throughout the product lifecycle
Solution Approach 2:
The scraper performs preliminary cleaning action on the rod and receptacle surfaces before the applicator withdraws product. By pre-clearing accumulated product and creating a clean interface, the scraper ensures that the next product withdrawal results in even distribution across the applicator, preventing the problem of uneven coverage when product is depleted
2Ease of operation
If the liquid cosmetic product is exposed to air, then the product can be accessed by the applicator, but the liquid tends to dry up and cannot be used anymore
Solution Approach 1:
The scraper element extracts and removes excess accumulated product from the rod and receptacle surfaces. By continuously clearing these surfaces, the scraper minimizes the amount of product exposed to air, reducing evaporation and drying while still allowing the applicator to access sufficient product for normal operation
Solution Approach 2:
The scraper provides continuous cleaning action during product withdrawal, maintaining a clean interface between the product, rod, and receptacle. This continuous action prevents large surfaces of product from being exposed to air simultaneously, reducing evaporation while ensuring uninterrupted product access
3Quantity of substance
If the applicator is immersed in the liquid cosmetic product, then the applicator can be impregnated with the cosmetic product, but too much liquid may be deposited on the applicator making it extremely difficult to apply
Solution Approach 1:
The scraper performs a partial cleaning action by removing only the excess accumulated product from the rod and receptacle surfaces, while leaving sufficient product in the receptacle for the applicator to withdraw. This partial removal prevents over-impregnation of the applicator, making application easier while still providing adequate product coverage
4Ease of operation
If the lid is not tightly closed, then the applicator can be easily accessed, but the liquid content may leak out of the container
Solution Approach 1:
The scraper performs preliminary cleaning of the rod and receptacle surfaces before the lid is closed. By removing accumulated product that could act as a seal disruptor, the scraper ensures that when the lid is closed (even not tightly), there is minimal risk of leakage while maintaining ease of access
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables easy and quick use of the cosmetic product regardless of the amount remaining, reduces solvent evaporation, and ensures precise dosing and minimal leakage, maintaining product quality.
Implementation Method 1
a containment and release body (6) arranged in said containment volume and impregnated with said cosmetic product
Implementation Method 2
suitable to be deformed by said applicator so as to release the cosmetic product on said applicator

AI summary
Provided is a packaging for a fluid product, in particular a cosmetic or a skin care product. The packaging may include a receptacle defining a containment volume of the cosmetic product and an opening into the containment volume. The packaging may further include a lid configured to engage with the receptacle and close the opening. Further, the packaging may also include an applicator configured to withdraw the cosmetic product from the containment volume. The packaging may additionally include a containment and release body arranged in the containment volume and saturated with the cosmetic product so that, when deformed by the applicator, it releases the cosmetic product on the applicator.
