Fixed Nozzle Cosmetic Pump With Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Pumping type cosmetic containers face challenges in accurately applying contents to the intended place due to moving discharge holes, leading to air leakage and content leakage issues.
Innovation Solution
A fixed nozzle and pumping type cosmetic container design where the nozzle remains stationary during button press, utilizing a leakage prevention part with a piston and opening/closing rod to control the discharge hole, and a fixation tube to minimize leakage by limiting the descent of the leakage prevention part.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the discharge hole is made movable to enable contents discharge, then contents can be discharged through pumping operation, but it becomes difficult to apply contents on an exactly intended place
Solution Approach 1:
The device is divided into separate functional components: a movable button part for operation, a stationary finishing cap with fixed nozzle for precise application, and a contents movement part that transfers contents without moving the discharge hole. This segmentation allows the discharge hole to remain fixed while still enabling contents discharge through the pumping mechanism.
2Reliability
If the piston is closely contacted to the inner circumferential surface of the nozzle to prevent leakage, then contents leakage is prevented, but a large amount of contents is leaked while contents at dead end are being discharged
Solution Approach 1:
The leakage prevention part is extracted as a separate component from the contents movement part. This separate leakage prevention part with piston closely contacts the nozzle inner surface to prevent leakage, while the contents movement part handles the discharge of contents from the dead end without causing excessive leakage.
Solution Approach 2:
The separate leakage prevention part acts as an intermediary between the contents movement part and the nozzle. It mediates the interaction by providing a sealing function through the piston while allowing the contents movement part to operate independently for discharging contents from the dead end.
3Reliability
If a separate leakage prevention part is provided to minimize contents leakage, then leakage is reduced, but device complexity increases
Solution Approach 1:
The leakage prevention part is integrated with the button part structure, merging the sealing function into an existing component rather than adding a completely separate assembly. This reduces overall device complexity while maintaining the leakage prevention capability through the piston mechanism.
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 precise application of contents to the intended place while preventing air leakage and minimizing content leakage through the separate leakage prevention mechanism.
Implementation Method 1
an upper portion of the movement tube is configured to have a shape of a piston which is closely contacted to an inner circumferential surface, a pressure is generated in a direction of the contents discharge hole while the movement tube is ascending
Implementation Method 2
a pumping member which is coupled to an upper portion of the container body and draws up the contents through a pumping operation by making the interior of the container body a state of vacuum
Implementation Method 3
a button part which is disposed at an upper portion of the pumping member and ascends/descends according to user's pressurizing, ang thereby transferring the pressure to the pumping member

AI summary
A fixed nozzle and pumping type cosmetic container, more specifically a fixed nozzle and pumping type cosmetic container wherein, since a pumping operation is performed in a state of a nozzle being fixated when a button is pressed, it is possible to apply contents on the exactly intended place, to prevent air from flowing by opening and closing a contents discharge hole by means of an opening and closing rod, and also to minimize leakage of contents through a leakage prevention part separately provided from a contents movement part.
