Solution Overview

Problem

Existing filler spouts face issues with liquid loss and increased cleaning complexity due to the need for a vacuum system to prevent liquid drops from forming at the spout's end, which complicates the filling process and increases maintenance time.

Innovation Solution

A filler spout design featuring a tubular body with a valve member and shutter mechanism that creates suction within a distribution chamber to prevent drop formation, using a servomotor or stepper motor actuator to control the valve's positions and ensure efficient liquid handling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a vacuum source is used to generate suction in the spout to prevent drop formation, then cleanliness of containers and installation is improved, but device complexity and liquid loss increase

Engineering Contradiction:
ImprovecleanlinessVSAvoiddevice complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The invention extracts the harmful liquid drop from the system by creating a localized suction zone at the spout outlet using a piston mechanism. The piston moves within the spout body to create negative pressure that draws the liquid drop back into the spout, preventing it from falling onto containers or the installation below.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The piston mechanism is driven by the liquid flow itself during the filling process. As liquid flows through the spout, it activates the piston movement automatically, creating the suction effect without requiring an external vacuum source. This self-service mechanism eliminates complex vacuum systems while maintaining cleanliness.

Inventive Principle:
Principle #25Self-service

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

This design effectively prevents liquid drops from forming at the spout's end, reducing liquid loss and simplifying the cleaning process by using a controlled suction mechanism, thereby maintaining cleanliness and improving operational efficiency.

Implementation Method 1

the valve member going from its extreme closing position to its intermediate closing position or from its intermediate closing position to its extreme closing position gives rise to suction in the distribution chamber, thereby preventing drop formation at the bottom end of the spout

AI summary

The invention relates to a filler spout comprising a tubular body having mounted therein both a valve member extending facing an inlet orifice of a distribution chamber and also a shutter arranged downstream from the valve member and rigidly connected thereto in such a manner as to extend facing an outlet orifice of the distribution chamber. An actuator is coupled to the valve member in order to move it between an extreme opening position and an extreme closing position, the valve member possessing an intermediate closing position in order to form a suction piston when the valve member is moved from the extreme closing position to the intermediate closing position or from the intermediate closing position to the extreme closing position. The shutter includes a channel opening into the distribution chamber and facing the outlet orifice of said distribution chamber so that the channel is always unobstructed regardless of the position of the valve member.
