Integrated Container Closure for Separate Storage and On-Demand Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container closures that require three separate components for mixing materials increase manufacturing costs and complexity due to multiple moldings and assembly steps.
Innovation Solution
A container closure assembly integrating an inner cup portion and an outer lid, where the inner cup portion contains the first material and the outer lid covers it, with a pressing portion to mix the second material by pressing the bottom portion, reducing the assembly process to one step and mold costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a container closure is composed of three separate members (storage cup, perforation cutter, outer lid), then the materials can be stored separately and mixed at use time, but the manufacturing cost increases and the manufacturing process becomes complex
Solution Approach 1:
The patent combines the storage cup and outer lid into a single integrated container closure component. The storage cup is formed as an integral part of the outer lid, eliminating the need for separate components. This merging reduces the number of parts from three to two, simplifies assembly operations, and reduces manufacturing complexity while maintaining the functionality of separate material storage and mixing capability
2Adaptability or versatility
If a container closure is composed of three separate members (storage cup, perforation cutter, outer lid), then the materials can be stored separately and mixed at use time, but the manufacturing cost increases due to multiple moldings and assembly steps
Solution Approach 1:
The storage cup and outer lid are merged into a single molded component, reducing the number of molding operations from three to two. This integration eliminates intermediate assembly steps, reduces labor costs, and simplifies quality control, thereby reducing overall manufacturing cost while preserving the separate storage and mixing functionality
Solution Approach 2:
The integrated container closure component serves multiple functions: it acts as both the outer lid for sealing the container and the storage cup for holding the second material. This multi-functionality eliminates the need for separate components, reducing both manufacturing complexity and cost while maintaining the ability to store and mix materials separately
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 integrated design allows separate storage and mixing of materials at use time, simplifying the manufacturing process and reducing costs by integrating the perforation cutter with the outer lid.
Implementation Method 1
a pressing portion (300) which is installed in the outer lid side wall portion (110) to be movable up/down and presses the bottom portion (230) when moving down so as to open the storage space (SS) downward

AI summary
The present invention relates to a container closure and container coupled with same. The present invention provides a container closure comprising: an inner cup portion (200) which is coupled to a container inlet (20) of a container (10) in which first material (1) is contained and in which a second material (2) mixed with the first material (1) is contained; and an outer lid (100) which is coupled to the container inlet (20) so as to cover the inner cup portion (200) coupled to the container inlet (20), wherein the inner cup portion (200) comprises: an inner cup side wall portion (210) which is inserted into the container inlet (20); a cup coupling portion (220) which is supported by at least one of the outer lid (100) and the container inlet (20) at the upper end of the inner cup side wall portion (210); and a bottom portion (230) which is integrally or detachably coupled to the lower end of the inner cup side wall portion (210) so as to form a storage space (SS) in which the second material (2) is contained. The outer lid (100) comprises: an outer lid side wall portion (110) which is screw-coupled to the container inlet (20), and a pressing portion (300) which is installed in the outer lid side wall portion (110) to be movable up/down and presses the bottom portion (230) when moving down so as to open the storage space (SS) downward.
