Multi-filling Container with Movable Partition Wall for Sequential Cosmetic Filling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for filling stick-type cosmetic containers, such as the front filling scheme, result in low productivity, poor surface gloss, and high defective molding rates, while the back filling scheme does not allow for the formation of smooth, aesthetically pleasing surfaces when filling two types of contents together.
Innovation Solution
A multi-filling container with a movable partition wall and a three-dimensional dome-shaped cover that allows for sequential filling of first and second contents through a lower injection port, enabling easy multi-filling and improved surface expression, along with a method involving preparation, first filling, partition wall removal, second filling, and cover removal steps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a multi-filling container with a movable partition wall and three-dimensional dome-shaped cover is used, then productivity and aesthetic appeal are enhanced with smooth surface expressions, but device complexity increases
Solution Approach 1:
The container is divided into multiple filling spaces using a movable partition wall that can be positioned to separate different cosmetic contents. This segmentation allows simultaneous filling of multiple products in a single container, directly improving productivity while maintaining manageable complexity through modular design
Solution Approach 2:
The partition wall is designed to be movable rather than fixed, allowing it to be positioned and secured at different locations within the container. This dynamic element enables flexible adaptation to different filling requirements and facilitates the multi-filling process, enhancing productivity without permanently increasing structural complexity
Solution Approach 3:
The container incorporates a three-dimensional dome-shaped cover that creates smooth, curved surfaces on the cosmetic products during filling. This curvature design enhances aesthetic appeal and surface expression while the domed structure naturally guides the filling process, improving productivity without requiring additional complex mechanisms
2Manufacturing precision
If sequential filling of first and second contents is performed using a movable partition wall, then surface gloss and aesthetic appeal are improved, but filling process complexity increases
Solution Approach 1:
The movable partition wall is positioned and secured before the filling process begins, creating predetermined separate spaces for different contents. This preliminary arrangement ensures that each cosmetic product fills its designated space without interference, achieving smooth surfaces and good gloss while simplifying the actual filling operation
Solution Approach 2:
By dividing the container into separate filling spaces using the partition wall, each cosmetic content can be filled independently through its own injection port. This segmentation prevents mixing of different products and allows each to achieve optimal surface gloss and aesthetic appearance without requiring complex control mechanisms during filling

Function Achieved in This Case
Enhances productivity and aesthetic appeal by allowing easy multi-filling of different contents with smooth, varied surface expressions, reducing defective products and improving usability.
Implementation Method 1
the movable partition wall is moved inward and outward of the stick-type content case, so that when different types of contents are filled into a lower portion of the stick-type content case
Implementation Method 2
filling first contents and second contents, and the first and second contents are solidified

AI summary
The present invention relates to a multi-filling container for stick-type contents and a method of filling the same, and more particularly, to a multi-filling container for stick-type contents, in which the multi-filling container is prepared by mounting a multi-filling cover having a three-dimensional shape on an inlet part of a stick-type content case, a movable partition wall is formed at a center of the multi-filling cover, and the movable partition wall is moved inward and outward of the stick-type content case, so that when different types of contents are filled into a lower portion of the stick-type content case, the movable partition wall is moved inward and outward of the stick-type content case to sequentially fill first contents and second contents, and the multi-filling cover is removed from the stick-type content case at a time when the first and second contents are solidified.
