Dispenser Pump Button Nozzle Dynamics for Contamination Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispenser pump buttons face challenges in preventing cap contamination and content spoilage, as the nozzle's exposure leads to contamination of the cap and potential air ingress, which can cause cosmetic container contents to spoil or become contaminated.
Innovation Solution
A dispenser pump button design featuring a nozzle that remains hidden within the button body but moves forward upon pressing, utilizing a guide member with a piston function to suck in remaining contents and an opening and closing rod to prevent air entry, ensuring efficient discharge without contaminating the cap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the nozzle is exposed to the outside for discharge, then the discharge function is improved, but the cap contamination increases
Solution Approach 1:
The nozzle is designed to move dynamically between two positions: retracted into the button body for storage and extended outward for discharge. This dynamic positioning allows the system to achieve both cap protection (when retracted) and effective discharge (when extended), resolving the contradiction between ease of operation and contamination prevention.
2Object-affected harmful factors
If the nozzle remains hidden in the button body, then cap contamination is prevented, but content discharge becomes difficult
Solution Approach 1:
The nozzle transitions from a static hidden position to a dynamic extended position during operation. When the button is pressed, the nozzle extends to enable content discharge, and when released, it retracts to protect the cap. This dynamic behavior resolves the contradiction by providing both protection and discharge capability at different operational states.
3Ease of manufacture
If air flows into the cosmetic container, then the container is easier to fill, but content spoilage increases
Solution Approach 1:
The opening and closing rod is extracted as a separate functional component that selectively opens the discharge hole only when needed for content discharge. During normal storage, the rod closes the hole to prevent air ingress and content spoilage. This extraction of the closing function into a dedicated component resolves the contradiction between filling ease and content preservation.
4Ease of operation
If the discharge hole remains open, then content discharge is facilitated, but air ingress and content spoilage increase
Solution Approach 1:
The discharge hole is designed to dynamically switch between open and closed states. The opening and closing rod controls this transition: when the button is pressed, the rod moves to open the discharge hole for content flow; when released, it closes the hole to prevent air ingress. This dynamic control resolves the contradiction between discharge facilitation and spoilage prevention.
5Productivity
If contents remain in the nozzle, then discharge efficiency is improved, but contamination and solidification problems occur
Solution Approach 1:
The guide member with piston function is designed to actively recover and remove residual contents from the nozzle after discharge. The piston moves to create negative pressure that sucks remaining contents back into the container, minimizing what would otherwise be wasted or contaminating residue. This recovery mechanism resolves the contradiction between discharge efficiency and contamination prevention.
6Productivity
If a guide member with piston function is added, then residual content removal is improved, but device complexity increases
Solution Approach 1:
The guide member integrates multiple functions into a single component: it guides the nozzle's linear movement, provides piston action for residual content removal, and maintains proper positioning. By merging these functions into one integrated component rather than separate parts, the design achieves effective residual removal while minimizing the increase in overall device complexity.
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
Prevents cap contamination and content spoilage by ensuring the nozzle is only exposed during discharge, minimizing residual contents and preventing air ingress, thus maintaining the cosmetic container's integrity.
Implementation Method 1
an elastic part one side of which is supported against the guide member, and the other side of which is supported against the inner side of the button body for thereby allowing the button body to move upward by providing an elastic force in an upward direction
Implementation Method 2
a guide member which is engaged to the inner side of the button body and is equipped with the guide groove of the nozzle and allows the nozzle to move back and forth when the button body moves up and down

AI summary
The present invention is the dispenser pump button. The dispenser pump button according to the present invention is designed so as to have a structure in which, when the button body is pressed, a nozzle which is normally positioned within the button body moves forward so as to be exposed to the outside from the button body and enable contents to be discharged, in order to prevent a cap from being contaminated.
