Refillable Cosmetic Container With Rotating Locking Couplers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers with integrated inner and outer parts are difficult to separate, leading to inconvenience in replacing the inner container and potential contamination during separation, and recycling is hindered by the use of non-detachable components like hinge pins.
Innovation Solution
A container design featuring a first container part fixed or separated from a second part via a locking mechanism that rotates around couplers, allowing easy detachment and recyclability, with detachable coupling between parts and transparent/semi-transparent materials for content visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the inner container and outer container are tightly coupled by adhesive to prevent separation, then the structural stability is improved, but the ease of operation deteriorates because the inner container cannot be easily replaced
Solution Approach 1:
The container is divided into separable components: an inner container and an outer container with a locking mechanism. The locking part can be rotated to either lock the inner container in place or unlock it for removal, allowing the system to switch between stable and replaceable states.
Solution Approach 2:
The locking mechanism transitions from a static adhesive bond to a dynamic mechanical lock that can be actively engaged or disengaged by rotating the locking part, enabling both stable operation and easy replacement as needed.
2Adaptability or versatility
If the inner container and outer container are made of different materials to improve functionality, then the adaptability is improved, but the ease of manufacture deteriorates due to the complexity of separation and recycling processes
Solution Approach 1:
The container system is segmented into distinct inner and outer containers that can be easily separated. This segmentation enables different materials to be used for each component while simplifying the recycling process, as each material can be recovered independently without complex separation procedures.
3Ease of operation
If a hinge pin is used to rotatably couple the covering part to improve the ease of operation, then the ease of operation is improved, but the ease of manufacture deteriorates because the hinge pin cannot be easily separated from the synthetic resin container
Solution Approach 1:
The hinge connection is segmented into separable components with protrusions and recesses that allow the covering part to be easily attached to and detached from the container body, replacing the permanent hinge pin connection with a reversible mechanical coupling.
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 replacement of the inner container, facilitates recycling, and prevents contamination during separation, while allowing for easy assembly and disassembly without hinge pins.
Implementation Method 1
each coupler has a pressurizer bent inward therefrom, if the locking part rotates in a first direction with respect to the couplers, to allow the outer peripheral surface of the first container part to be pressurizedly fixed thereto

AI summary
A container includes: a first container part for storing a given content therein; a second container part having couplers disposed on a top thereof in such a way as to surroundingly fix the outer peripheral surface of the first container part thereto; and a locking part rotatably coupled to the couplers in such a way as to surround the outer peripheral surfaces of the couplers, wherein each coupler has a pressurizer bent inward therefrom, if the locking part rotates in a first direction with respect to the couplers, to allow the outer peripheral surface of the first container part to be pressurizedly fixed thereto.
