Discharge Pump Roller Mechanism for Bag-in-Box Liquid Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional beverage supply devices using bag-in-box systems face challenges with high manufacturing costs due to the need for elastic tubes to withstand pressure, complex tube attachment mechanisms, and time-consuming tube handling, which complicates container exchange and maintains sanitary conditions.
Innovation Solution
A discharge pump with a flexible container featuring a discharge passage part that uses roller parts and an endless transfer mechanism to press and squeeze the passage part, allowing for controlled liquid discharge without external tubes, reducing manufacturing costs and simplifying the mechanism while maintaining sanitary conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If elastic tubes are used to withstand the pressure of rotation rollers, then the tube can reliably discharge liquid, but the manufacturing cost of the container increases
Solution Approach 1:
The invention extracts the tube component from the system by using the discharge passage part of the flexible container itself as the discharge path, eliminating the need for separate elastic tubes and reducing manufacturing costs while maintaining discharge reliability
Solution Approach 2:
The discharge passage part of the flexible container is designed to serve multiple functions: it acts as both the liquid reservoir connection and the discharge path, replacing the need for separate tubes and simplifying the overall structure
2Manufacturing precision
If tubes are attached to tube pumps for proper liquid discharge, then discharge control is improved, but tube handling time increases and container exchange becomes complicated
Solution Approach 1:
The invention merges the container and discharge mechanism by integrating the discharge passage part directly into the flexible container structure, allowing the container to be attached to and detached from the discharge pump as a single unit, which simplifies handling and reduces time loss
Solution Approach 2:
The flexible container's discharge passage part is designed to be self-sufficient for liquid discharge without requiring separate tubes, enabling the container to serve its own discharge needs and simplifying the attachment/detachment process
3Productivity
If rotation rollers press the discharge tube, then liquid can be discharged, but another material tube is required which increases cost
Solution Approach 1:
The invention changes the material parameter of the discharge passage from requiring separate elastic tube material to using the container's own flexible material, which is already designed to withstand the pressing force of rotation rollers, thereby reducing material costs
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
The solution enables reliable, cost-effective, and sanitary liquid discharge from flexible containers by using the container's own discharge passage part, eliminating the need for additional tubes and simplifying the structure, while ensuring proper liquid dispensing and easy container exchange.
Implementation Method 1
roller parts that press the discharge passage part
Implementation Method 2
endless transfer mechanism unit that has the plurality of roller parts attached at a predetermined interval and moves the roller parts to cause the roller parts to go around

AI summary
A flexible container (80) includes a reservoir part (82) that reserves a liquid and a discharge passage part (81) that communicates with the reservoir part (82) to take out the liquid. A discharge pump includes a plurality of roller parts (50) that press the discharge passage part (81) and an endless transfer mechanism unit (60) that has the plurality of roller parts (50) attached at a predetermined interval and causes the roller parts (50) to go around. The endless transfer mechanism unit (60) has an arrangement including a straight-line portion in which the roller parts (50) linearly move, in a path of the go-around movement. An attachment interval of the plurality of roller parts (50) is set to such an interval that before a certain roller part (50) going around reaches a position where the certain roller part (50) does not press the discharge passage part (81), a subsequent roller part (50) is able to reach a position where the subsequent roller part (50) presses the discharge passage part (81). Each of the roller parts (50) linearly moves sequentially in a discharge direction of the liquid with respect to the discharge passage part (81) while pressing the discharge passage part (81).
