Rotary Valve Pump Container for Granule Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pump containers for granule type cosmetics often rupture the encapsulated granules during discharge, making it difficult for users to confirm the integrity of the contents and potentially degrading the product's effectiveness.
Innovation Solution
A pump container design featuring a rotary support mechanism for the opening/closing plate of the valve member, which rotates to open/close the content inflow and movement tubes, ensuring encapsulated granules are not ruptured during the pumping operation, with a sealing cap to manage pressure and a button member for user-activated discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional pump structure with check valves is used to discharge granule cosmetics, then the pumping operation can be performed, but the encapsulated granules may be ruptured during discharge through the valve
Solution Approach 1:
The valve member is segmented into a valve body and a separate opening/closing plate that can rotate independently. This segmentation allows the closing plate to open the content inflow hole and content movement tube in a controlled manner during pumping, preventing granule rupture while maintaining ease of operation
Solution Approach 2:
The opening/closing plate is designed to rotate dynamically between open and closed positions rather than being fixed. This dynamic rotation allows the valve to adapt to the pumping operation while maintaining granule integrity by controlling when the content movement tube is open or closed
2Loss of information
If granule type cosmetics are discharged through a conventional pump, then discharge function is achieved, but users cannot confirm whether granules are ruptured and mixed during discharge
Solution Approach 1:
The content movement tube is extracted as a separate, visible component that users can directly observe. The tube's upper end is positioned at the button member level, allowing users to see whether granules are intact or ruptured during discharge, while the pumping operation continues efficiently
Solution Approach 2:
The content movement tube serves as an intermediary between the pumping chamber and the discharge point. It provides a visible pathway that allows users to monitor granule integrity while still enabling efficient pumping operation through the valve 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 the reliable discharge of granule contents without rupture, allowing users to confirm the intactness of the granules and maintaining the product's effectiveness by preventing premature mixing and degradation.
Implementation Method 1
an opening/closing plate of a valve member is coupled to the inner peripheral surface of a valve body through a rotary support to rotate up and down so as to open/close a content inflow hole and an upper end of a content movement tube
Implementation Method 2
a sealing cap which is coupled encasing an lower portion of the content moving tube and closely contacted to an inner wall of the cylinder, thereby changing an inner pressure of the cylinder according to the ascent/descent

AI summary
The present invention disclosed herein relates to a pump container for discharging capsules, in which an opening/closing plate of a valve member is coupled to the inner peripheral surface of a valve body through a rotary support to rotate up and down so as to open/close a content inflow hole and the upper end of a content movement tube, such that encapsulated granule contents can be discharged, without rupturing, during a pumping operation of a pumping member.
