Flexible Cosmetic Cap Sealing for Multi-Size Applicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cosmetic applicators face issues such as material drying, hardening, or becoming unusable due to prolonged exposure to air, and contamination from external particles when not properly sealed, leading to inefficiency and resource waste.
Innovation Solution
A flexible, all-purpose cap designed to removably engage applicators of various sizes, forming a seal to prevent exposure to external conditions and accommodate different shapes and sizes, using deformable materials with antimicrobial properties.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the application segment is left exposed for easy access, then ease of operation is improved, but the material dries, hardens, or becomes unusable due to prolonged exposure to air
Solution Approach 1:
The cap is designed to be placed on the applicator before storage or transport, creating a preliminary protective barrier that prevents material exposure to air. This preliminary action maintains material usability without requiring complex sealing mechanisms or user intervention during storage.
2Productivity
If the application segment is exposed for frequent use, then productivity is improved, but external particles contaminate the application segment, lowering cleanliness
Solution Approach 1:
The cap serves as an intermediary protective element between the application segment and the external environment. It allows the application segment to remain exposed during use for productivity while providing a barrier during storage to prevent contamination from external particles.
3Reliability
If a custom-fit cap is designed for each applicator size, then reliability of seal is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The cap is designed with universal applicability to fit multiple applicator sizes through a standardized engagement mechanism. The cap can accommodate different applicator diameters while maintaining reliable sealing, eliminating the need for multiple custom-fit cap designs for different applicator sizes.
Solution Approach 2:
The cap incorporates adjustable or flexible parameters in its design, such as elastic materials or expandable structures, that allow it to adapt to different applicator sizes while maintaining a reliable seal. This parameter flexibility enables a single cap design to serve multiple applicator dimensions.
4Loss of substance
If material is stored in an applicator for extended periods, then loss of substance is reduced, but material dries or hardens due to exposure to air
Solution Approach 1:
The cap provides preliminary protection against air exposure by creating a barrier before the material can undergo drying or hardening. This preliminary anti-action prevents the harmful effects of prolonged exposure, maintaining material consistency and reducing waste from unusable material.

AI summary
A cap can be configured to engage with cosmetic application devices (also referred to as “applicators” or “cosmetic implements”) of various sizes. The cap may include a rigid housing and a flexible body within the rigid housing comprised of elastic material. The flexible body includes a cavity that extends from an opening in the proximal end portion toward the distal end portion of the cap and varies in diameter along its length. The cap may receive an application segment of an applicator through the opening, and the inner surface of the cap can apply pressure to a surface of the applicator to form a seal between the applicator and the cap. The seal between the applicator and the cap protects the application segment from dust and debris and prevents fluid in the applicator segment from drying or hardening.
