Self-Venting Dispensing Tap for High-Flow Viscous Liquids
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispensing taps for liquids suffer from ergonomic and functional issues, such as difficult manipulation and slow flow rates, making them unsatisfactory for consumer use.
Innovation Solution
A dispensing tap design featuring an ergonomic structure with a high flow rate, incorporating a piston with a peripheral seal and a spring-biased shut-off valve, and a self-venting system that opens simultaneously with the valve, allowing for easy operation and rapid fluid discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a conventional valve mechanism is used, then the structure is simple, but the flow rate is slow and the valve is difficult to manipulate
Solution Approach 1:
The patent employs a dynamic piston mechanism that moves axially within the dispensing head, allowing the valve to transition smoothly between closed and open positions. This dynamic design enables rapid opening/closing action and facilitates easy manipulation by the consumer, directly addressing the contradiction between simple structure and ease of operation while achieving high flow rates.
2Reliability
If the valve closes tightly to prevent leakage, then sealing is improved, but air becomes trapped inside the container causing dispensing issues
Solution Approach 1:
The patent introduces a vent mechanism that acts as an intermediary between the sealed valve system and the external environment. This vent allows trapped air to escape during dispensing operations while maintaining the tight sealing performance of the valve, thereby resolving the contradiction between reliable sealing and preventing air trapping that causes dispensing problems.
3Productivity
If the outlet area is increased to improve flow rate, then productivity increases, but the valve becomes harder to control precisely
Solution Approach 1:
The patent segments the flow control function by using a piston with a peripheral seal that can move independently within the dispensing head. This segmentation allows the valve to control a large outlet area effectively, maintaining precise control while achieving high flow rates, thus resolving the contradiction between productivity and ease of operation.
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 design provides an ergonomic and efficient dispensing solution with a high flow rate for high-viscosity fluids, enhancing user experience and reducing the need for prolonged tap activation.
Implementation Method 1
a spring captured between the piston and the dispensing head and normally biasing said piston and shut off valve to said closed position
Implementation Method 2
said peripheral seal is configured for sealing engagement with said vent opening, said peripheral seal being engaged with said vent opening when said piston is in said closed position

AI summary
A dispensing tap (100) for liquids includes a body (102) connected to the neck (902) of a container (900), a dispensing head (108) with an outlet or mouth (114), and a throat (110 Connecting the body (102) to the dispensing head (108). A shut off valve (116) is configured for sealing engagement with the mouth of the dispensing head, and a piston (118) is axially guided within the dispensing head. The piston includes a periperhal seal (120) slidably engaged with an interior surface of the dispensing head, and a valve stem (122) coupled to the shut off valve. The piston is selectively actuable between a normally closed position an open position. A spring (134) is captured between the piston and the dispensing head normally biasing the piston and shut off valve to the closed position. A vent is (140) in communication with an interior of the body and the vent is opened and closed with movement of the piston and shut off valve.
