Adjustable Cosmetic Pump Dispensing Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers with pumps lack consistency in dispensing amounts due to varying downward force applied, and mixing containers face issues with premature mixing and performance degradation, necessitating a solution for adjustable content dispensing.
Innovation Solution
A cosmetic container design featuring a rotatable handle with an adjustment member and a pump system, where the adjustment member's pressure protrusion controls the dispensing amount by altering the valve's movement, allowing precise adjustment of the dispensing quantity and enabling separate dispensing of multiple contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional pump is used for dispensing cosmetic content, then the content can be dispensed through pressure change, but the dispensing amount varies according to the downward force applied and cannot be accurately adjusted
Solution Approach 1:
The pump system incorporates an adjustable valve mechanism that allows the downward movement distance of the valve to be dynamically changed. By rotating the adjustment member, users can modify the position where the valve stops moving downward, thereby controlling the dispensing amount. This dynamic adjustment capability resolves the contradiction by enabling both ease of operation and precise control over dispensing consistency.
Solution Approach 2:
The invention changes the parameter of valve movement distance to control dispensing amount. The adjustment member modifies the structural parameter of the pump system by altering the stopping position of the valve, which directly affects the volume of content dispensed. This parameter change approach allows users to achieve consistent and accurate dispensing amounts while maintaining simple operation.
2Reliability
If two types of contents are stored separately and mixed at the time of use, then premature mixing is prevented, but providing a constant mixing ratio is difficult without adjustment functionality
Solution Approach 1:
The dual pump system incorporates adjustable valve mechanisms in both pumps, allowing the downward movement distance of each valve to be independently modified. By rotating the adjustment member, users can set different stopping positions for each pump's valve, thereby controlling the dispensing amount of each content. This dynamic adjustment capability enables precise control over mixing ratios while maintaining content stability through separate storage and mixing-at-use functionality.
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 consistent and adjustable dispensing of cosmetic contents, preventing premature mixing and maintaining performance by allowing users to control the dispensing amount and mixing ratio effectively.
Implementation Method 1
a pump that is configured to suction and dispense the content held in the outer container and is configured such that a pressing on a portion thereof by the pressure protrusion changes an amount of content dispensed

AI summary
The invention relates to a cosmetic container capable of adjusting the amount of content dispensed. A cosmetic container according to one aspect of the invention comprises: an outer container that holds a content; a handle that is rotatably coupled to an upper portion of the outer container; an adjustment member that is coupled to an upper portion of the handle to rotate as an integrated body with the handle and is provided with a downwardly protruding pressure protrusion; and a pump that is configured to suction and dispense the content held in the outer container and is configured such that a pressing on a portion thereof by the pressure protrusion changes an amount of content dispensed, where rotating the adjustment member adjusts a discharging amount of the pump by adjusting the extent to which the pressure protrusion presses the pump.
