Rotatable Handle Cosmetic Container with Adjustable Pump Stroke
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cosmetic containers with pumps lack precise control over dispensing amounts, as the amount dispensed varies with the force applied to the pump, and existing mixing containers for combining different contents do not provide an easy way to adjust dispensing ratios.
Innovation Solution
A cosmetic container design featuring a rotatable handle with a protrusion system that allows easy adjustment of dispensing amounts by rotating a pressing protrusion, enabling precise control over the mixture ratio of two different contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional pump is used for dispensing content, then the content can be protected from exposure and spoiled, but the dispensing amount cannot be controlled precisely as it varies with the force applied
Solution Approach 1:
The pump system incorporates an adjustable stroke length mechanism that allows the pumping distance to be dynamically changed. The pump stroke adjusting member can be positioned at different locations along the pump rod, thereby controlling the distance the pump rod travels during each pumping action. This dynamic adjustment capability enables precise control over the dispensing amount while maintaining the protective sealing function of the pump system.
2Adaptability or versatility
If a mixing container is used to combine two different contents, then synergic effects can be achieved, but the dispensing amounts and mixture ratio cannot be easily adjusted
Solution Approach 1:
The container system integrates multiple functions into a unified structure: it can store different types of content in separate chambers, dispense each content through dedicated pumps, and control the mixing ratio of combined dispensing. The pump stroke adjusting members allow independent adjustment of each pump's dispensing amount, enabling flexible mixture ratio control while maintaining the synergic mixing function.
Solution Approach 2:
The system controls the mixing ratio by changing the stroke length parameter of each pump. By adjusting the position of the pump stroke adjusting members along the pump rods, the dispensing amount of each content type can be precisely controlled. This parameter-based control mechanism enables easy adjustment of mixture ratios without complex operations, simply by repositioning the adjusting members to desired locations.

AI summary
An embodiment relates to a cosmetic container with which the dispensing amounts of the contents can be varied. The cosmetic container may include: an outer container holding a content; a shoulder coupled to the outer container and comprising a shoulder protrusion; a handle rotatably coupled to the shoulder and comprising a handle protrusion into which the shoulder protrusion is rotatably inserted; an adjustment member that is coupled to the handle to rotate together with the handle as an integrated body and includes a downwardly protruding pressing protrusion; and a pump that is configured to suction and dispense the content held in the outer container and configured such that a dispensing amount of the content is changed by a rotation of the pressing protrusion, where the shoulder protrusion includes a shoulder hook, and the shoulder hook is caught on an upper end of the handle protrusion.
