Dispensing Device Intermediate Valve Viscous Liquid Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing devices struggle with precision when dispensing sticky and viscous liquids, often leading to incomplete dosing due to slow flow rates, which can result in user errors.
Innovation Solution
A dispensing device with a first and second chamber, where the first chamber is slidably movable and equipped with an intermediate valve that allows precise control of liquid flow, ensuring all measured liquid is dispensed through an outlet passage, preventing direct pouring and ensuring consistent doses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an intermediate wall with inclined or curved portion is used to trap liquid product, then liquid product can be prevented from passing directly through the dispensing device, but sticky and viscous liquid flows slowly out of the dispenser
Solution Approach 1:
The patent introduces an intermediate valve as a mediator component between the first and second chambers. This valve includes a valve body with a valve opening and a valve element that can open and close the opening, controlling liquid flow precisely. The intermediate valve acts as an intermediary mechanism that enables complete evacuation of viscous liquids while preventing direct pouring through the dispensing device.
2Measurement precision
If a first chamber is made longitudinally slidably movable in the second chamber, then precise control of liquid flow is achieved, but device complexity increases
Solution Approach 1:
The patent divides the dispensing device into distinct segments: a first chamber for receiving liquid product and a second chamber for dispensing, separated by an intermediate valve. This segmentation allows each chamber to have specific functions and enables precise control of liquid flow while maintaining a relatively simple overall structure. The intermediate valve is positioned to divide the interior part of the dispensing device into these two functional chambers.
3Reliability
If the first chamber is made movable to enable complete dosing, then all measured liquid can be dispensed, but ease of operation decreases
Solution Approach 1:
The intermediate valve is designed to automatically open and close based on the movement of the first chamber relative to the second chamber. When the first chamber is moved longitudinally, the valve element responds to pressure changes and positional changes to open the valve opening for filling and close it for dispensing. This self-service mechanism eliminates the need for manual valve control, maintaining ease of operation while ensuring complete dosing.
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 device provides precise and reliable dispensing of sticky and viscous liquids, ensuring complete dosing without direct pouring, enhancing user trust in consistent dose delivery.
Implementation Method 1
The at least one flapper moves to an open position allowing the liquid product to flow from the interior space of first chamber to the interior space of the second chamber
Implementation Method 2
moves to a closed position limiting flow of the liquid product from the interior space of the second chamber to the interior space of the first chamber

AI summary
A dispensing device includes a that is longitudinally movable in a second chamber and has an outer surface sealingly contacting an inner surface of the second chamber. An intermediate valve is positioned between an interior part of the first chamber and an interior part of the second chamber. The intermediate valve includes a valve seat plate having at least one opening and a valve flapper plate having at least one flapper for covering the at least one opening in the valve seat plate. The at least one flapper moves to an open position allowing the liquid product to flow from the interior space of first chamber to the interior space of the second chamber when the first chamber is moved in a first longitudinal direction and moves to a closed position limiting flow of the liquid product when the first chamber is moved in an opposite second longitudinal direction.
