Squeeze Dispenser Valve for Fast Liquid Outfeed Without Spillage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices for feeding out liquid contents from flexible squeezable containers are inefficient in dispensing large quantities, require slow valve operation, and are difficult to clean.
Innovation Solution
A device with a discharge mechanism that uses a pressure plate and lever system to apply pressure from above, coupled with an elastic valve body that opens and closes quickly to facilitate rapid dispensing and easy cleaning, ensuring minimal spillage and complete emptying of the container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional valve mechanism is used, then the device structure is simple, but the valve opens and closes slowly causing spillage and cannot rapidly dispense large quantities
Solution Approach 1:
The valve body is designed with elastic properties and a specific normal shape that allows it to rapidly change state between closed and open positions. When pressure from the storage container increases, the valve body stretches and quickly transitions from its normal shape to an open state, enabling rapid dispensing without spillage.
Solution Approach 2:
The valve body is designed to be dynamically responsive to pressure changes. It automatically transitions between closed and open states based on the pressure from the storage container contents, enabling rapid opening and closing without manual intervention and preventing spillage during the transition.
2Productivity
If manual squeezing is used to dispense contents, then the device structure is simple, but large quantities cannot be dispensed quickly and the process is time-consuming
Solution Approach 1:
A pressure means is provided that can apply hydraulic pressure to the storage container through a pressure application means. This allows large quantities of contents to be dispensed quickly by forcing the flexible storage container through pressure rather than manual squeezing, significantly reducing dispensing time.
Solution Approach 2:
The pressure application means is movable relative to the storage container, allowing pressure to be applied from above in a vertical dimension. This enables rapid compression of the storage container to dispense large quantities quickly, rather than relying on horizontal manual squeezing motions.
3Productivity
If the valve body is rigid for structural stability, then the valve seat connection is secure, but the valve cannot open quickly in response to pressure changes
Solution Approach 1:
The valve body is designed with elastic properties that allow it to change its physical state in response to pressure. It maintains sufficient structural integrity to connect securely to the valve seat in its normal shape, but can rapidly stretch and deform to open the valve when pressure from the storage container increases, enabling quick opening without sacrificing connection security.
4Ease of operation
If the valve means is complex for precise control, then the valve operation is accurate, but the valve means becomes difficult to clean and maintain
Solution Approach 1:
The valve body automatically opens and closes in response to pressure changes from the storage container contents, without requiring complex control mechanisms. This self-regulating operation maintains precise valve control while keeping the valve means simple in structure, making it easy to clean and maintain.
Solution Approach 2:
The valve means is designed as a separable component that can be easily removed from the outfeed container for cleaning. The valve body with its elastic properties provides the necessary control function while the modular design allows for easy disassembly and cleaning, reducing maintenance difficulty.
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 quick and efficient dispensing of large quantities with minimal spillage and easy cleaning, ensuring the container is emptied completely without remnants.
Implementation Method 1
The valve body has elastic properties and a normal shape in which it abuts against the valve seat so that it closes the valve means (9). The shape of the valve body is also variable so that when the valve body is subjected, for outfeed, to a specified pressure from the contents of the storage container (2), it is caused to change to a stretched shape.
Implementation Method 2
The discharge means (6) comprises a pressure means (11) and a pressure application means (12) which, via the pressure means (11), exerts from above upon the storage container (2) in the outfeed container (3) a pressure for outfeed of the contents from the storage container at the bottom of it.

AI summary
A device for feeding out liquid or substantially liquid contents from a storage container (2) comprises an outfeed container (3) for the storage container and a discharge means (6) for outfeed of the contents from the storage container by squeezing it. The storage container (2) has an inner connecting element (7) for connection to an outer connecting element (8) by the latter's penetration of the container wall at the inner connecting element. The storage container (2) is connected via the outer connecting element (8) to a valve means (9) with a valve body (10) which in a resting position abuts against a valve seat and which, for outfeed, is open able by the contents of the storage container being pressed against the valve body so that the latter leaves the valve seat. The valve body (10) has elastic properties and a normal shape when it abuts against the valve seat so that it closes the valve means (9). For outfeed, the valve body (10) assumes a stretched shape and leaves the valve seat. The valve body (10) quickly reverts from stretched to normal shape when the pressure upon it from the contents of the storage container (2) ceases. The discharge means (6) of said device comprises a pressure means (11) and a pressure application means (12) which, via the pressure means, exerts upon the storage container (2) in the outfeed container (3) a pressure for outfeed of the contents from the storage container.
