Inverted Liquid Dispenser Valve for Accurate Gravity Portioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems require staff members to manually pour and measure liquid from storage containers, introducing variability and increasing labor and downtime, especially in large chain stores.
Innovation Solution
A system that allows liquid to be dispensed directly from its original storage container using gravity, controlled by a positive pressure valve assembly and air flow, enabling accurate portioning and reducing physical effort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If staff manually pour and measure liquid from storage containers, then liquid can be dispensed, but labor time and measurement variability increase
Solution Approach 1:
The liquid storage container is designed to automatically dispense liquid through its own integrated valve mechanism when inverted, eliminating the need for staff to manually pour and measure. The container serves itself by controlling the liquid flow through the valve assembly, which opens automatically when the container is inverted and closes when set upright.
Solution Approach 2:
A valve assembly acts as an intermediary between the liquid storage container and the dispensing system. This valve mechanism mediates the liquid flow, allowing automatic controlled dispensing without direct staff intervention in the pouring process.
2Quantity of substance
If liquid is poured from storage container into holding tank, then liquid can be stored for dispensing, but transfer time and cleaning downtime increase
Solution Approach 1:
The invention extracts the liquid directly from the original storage container and dispenses it without transferring to an intermediate holding tank. By removing the holding tank step, the system eliminates both the transfer time and the cleaning downtime associated with maintaining a separate storage vessel.
Solution Approach 2:
The storage container serves dual functions: it both stores the liquid and directly dispenses it to the customer. This multi-functionality eliminates the need for a separate holding tank, reducing both transfer operations and cleaning requirements.
3Ease of operation
If staff estimate liquid amount manually, then dispensing can be performed, but measurement precision and consistency decrease
Solution Approach 1:
The invention replaces the manual mechanical estimation process with an automated valve-controlled dispensing system. The valve mechanism provides consistent, repeatable liquid flow control based on predetermined parameters, eliminating the variability inherent in manual estimation while maintaining operational simplicity.
4Use of energy by moving object
If storage container is inverted for dispensing, then liquid flows by gravity, but container stability and handling difficulty increase
Solution Approach 1:
The system dynamically transitions the container between inverted (dispensing) and upright (storage/transport) positions. The valve assembly is designed to function in both orientations, allowing the container to be easily handled in the upright position for storage and loading, then inverted for dispensing, and returned to upright position when done.
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
Accurately dispenses liquid without transfer, reducing labor and variability, and maintaining consistent food preparation across locations.
Implementation Method 1
The container includes a dispensing opening that provides a point of exit for the liquid from the container. The liquid flows out of the dispensing opening of the container under the influence of gravity.
Implementation Method 2
A positive pressure valve assembly is designed to be used with the container to control the flow of liquid from the container when the container is inverted in the cabinet.

AI summary
A liquid dispenser for dispensing a consumable liquid from a container. The dispenser includes a cabinet configured to receive one or more containers in an inverted position such that liquid is induced by gravity to flow out of an open interior of the container though a dispensing opening. A positive pressure valve assembly is mounted to the dispensing opening of the container prior to insertion of the container into the cabinet. The valve assembly includes a cap connected to the dispensing opening and a discharge tube extending from the cap. A flow restrictor of the valve assembly is positioned to selectively open and close the discharge tube to control the flow of liquid from the container. A one-way valve is positioned between the open interior of the container and a supply of air. The one-way valve allows air flow into the container as the fluid is discharged to maintain a positive pressure within the container.
