Cosmetic Container With Friction-Fit Molding Capsule
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cosmetic product containers do not efficiently dispense and protect cosmetic products, particularly lip balms, and lack a secure mechanism for easy access and exposure of the product after assembly.
Innovation Solution
A container system comprising two semi-spherical members with threaded connections, a molding capsule with a base structure and forming cup, and a planar grid support, allowing for secure coupling and easy access to the cosmetic product by detaching the second container member, which remains attached to expose the product.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the container uses a two-member coupled structure, then the product protection and security are improved, but the device complexity increases
Solution Approach 1:
The container is divided into two separate members (first container member and second container member) that can be coupled together to form a complete container. This segmentation allows the container to be assembled in a secure manner while protecting the cosmetic product, resolving the contradiction between improved product protection and increased structural complexity.
2Ease of operation
If the second container member remains attached to the forming cup after uncoupling, then the ease of access to product is improved, but the device complexity increases
Solution Approach 1:
The forming cup is pre-attached to the second container member through a friction fit mechanism before the container is assembled. This preliminary attachment ensures that when the container members are uncoupled, the forming cup remains with the second member, automatically exposing the cosmetic product without requiring additional complex mechanisms.
3Strength
If threaded connections are used between container members, then the coupling security is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The threaded connections between container members utilize standard thread parameters and tolerances that balance coupling security with manufacturability. By optimizing thread pitch, diameter, and engagement length, the design achieves secure coupling without requiring excessively tight manufacturing precision, resolving the contradiction between strength and manufacturing precision.
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
The container system effectively stores and dispenses cosmetic products by securely coupling and decoupling the members, ensuring easy access and protecting the product from contamination during filling and use.
Implementation Method 1
The base structure is frictionally coupled to the interior surface of the first container member. The forming cup is frictionally coupled to the interior surface of the second container member

AI summary
A container for dispensing a cosmetic product includes a first container member and a second container member shaped and dimensioned for coupling together so as to define a cavity therebetween for storing the cosmetic product. A molding capsule is positioned within the cavity between the first container member and the second container member. The molding capsule includes a base structure coupled to the interior surface of the first container member, the base structure having an aperture through which the cosmetic product is fed. The molding capsule also including a forming cup coupled to the interior surface of the second container member, the forming cup having an interior surface which defines the shape of a cosmetic product. The base structure and the forming cup define a molding cavity in which the cosmetic product is stored.
