Integrated Filter Capsule for Inclusion-Free Cosmetic Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional service capsules for cosmetic product packaging are not suitable for dispensing products with inclusions, leading to unpleasant user experiences due to the inclusion of solids with the product, and are complex to manufacture with multiple parts made from different materials.
Innovation Solution
A service capsule with a filter integrated into the product dispensing conduit, which ensures that the cosmetic product passes through the filter during extraction, preventing inclusions from being dispensed, and featuring a simplified design with fewer components for easier manufacturing, including a pyramidal or flat filter shape to enhance passage surface and reduce agglutination risks, and a sealing cap for complete closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a filter is added to the service capsule to prevent inclusions from being dispensed, then the user experience is improved, but the device complexity increases due to multiple parts made from different materials
Solution Approach 1:
The patent merges the filter with the transverse wall by integrating the filter directly into the wall structure. This combination eliminates the need for separate filter components while maintaining the filtering function, thus improving user experience without increasing device complexity
Solution Approach 2:
The transverse wall is designed to serve multiple functions: it provides structural closure, defines the outlet orifice, and incorporates the filter function within its structure. This multi-functionality reduces the number of separate components needed, resolving the contradiction between adding filtering capability and maintaining simplicity
2Reliability
If a filter is integrated into the dispensing conduit, then the filtering function is improved, but the manufacturing complexity increases due to multiple materials
Solution Approach 1:
The filter is merged with the transverse wall structure, combining filtering functionality with an existing structural component. This integration reduces the number of separate parts that need to be manufactured and assembled, thereby improving filtering reliability while maintaining ease of manufacture
Solution Approach 2:
The transverse wall is designed as a composite structure that incorporates filtering material within its construction. This allows the wall to simultaneously provide structural support and filtering function, improving filtering reliability without requiring separate filter components that would increase manufacturing complexity
3Reliability
If the filter is positioned upstream from the dispensing conduit, then the filtering effectiveness is improved, but the device complexity increases due to additional components
Solution Approach 1:
The filter is merged with the transverse wall structure, combining the filtering function with an existing structural component. This integration maintains filtering effectiveness while eliminating the need for separate filter components, thus reducing device complexity
4Reliability
If the cap is designed to completely close the outlet orifice, then the sealing function is improved, but the device complexity increases due to additional sealing components
Solution Approach 1:
The sealing function is merged with the cap structure by incorporating a sealing finger directly into the cap. This integration allows the cap to provide both closure and sealing functions, improving sealing reliability without requiring separate sealing components

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 effective dispensing of cosmetic products with inclusions without unpleasantness to the user, while maintaining ease of manufacturing and ensuring a secure seal to prevent leakage, using a simplified design that integrates the transverse wall, dispensing conduit, and filter for efficient filtering and sealing.
Implementation Method 1
a filter (38) arranged upstream from and/or in the product dispensing conduit (36), the filter (38) being configured so that the cosmetic product present in the container (18) necessarily passes through the filter (38) when the product (12) is extracted from the container (18) through the service capsule (20)
Implementation Method 2
the cap (40) comprises a sealing finger (62) inserted in a watertight way into the dispensing conduit (36) in the applied position

AI summary
The service capsule (20) comprises:—an outer skirt (32),—a transverse wall (34) defining at least one outlet orifice (48). The service capsule (20) includes, for each orifice (48), a dispensing conduit (36) defining a dispensing passage (51). The service capsule (20) includes a closing cap (40), mounted moving between a clear position and a position applied on the transverse wall (34). A filter (38) is arranged upstream from and/or in the product dispensing conduit (36), and is configured so that the cosmetic product (12) in the container (18) necessarily passes through the filter (38) when the product (12) is extracted from the container (18) through the service capsule (20). The filter (38) is integral with the product dispensing conduit (36).
