Pivotable Spout Valve with Locking Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spout arrangements for containers storing free-flowing media are complex, prone to leakage, and result in contamination due to residual media in the spout and container, with loose parts required for sealing, leading to potential spills and loss during handling.
Innovation Solution
A spout arrangement with a pivotable spout pipe and locking mechanism, combined with a compression spring to ensure secure sealing, allows controlled pouring without loose parts, preventing accidental opening and ensuring the container remains sealed when not in use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional spout arrangements with loose sealing parts are used, then the container can be sealed when not in use, but the handling becomes complex and the risk of free pouring increases
Solution Approach 1:
The invention integrates the sealing function directly into the spout structure itself, eliminating the need for separate loose sealing parts. The spout is designed with an integrated closure mechanism that seals the pouring opening without requiring additional caps or plugs, thereby simplifying handling while maintaining sealing reliability.
Solution Approach 2:
The spout arrangement is designed to be self-sealing through its structural configuration. The spout automatically maintains its sealed state without requiring additional sealing components, and the user can control pouring simply by manipulating the spout itself, reducing the complexity of handling multiple separate parts.
2Adaptability or versatility
If movable bellows are used as the spout for better position adjustment, then the spout can adapt to different filling positions, but residual media remains in the grooves causing contamination
Solution Approach 1:
The invention employs a flexible spout structure that can bend and adapt to different positions without creating grooves or recesses where media can accumulate. The smooth, continuous surface of the flexible spout allows complete drainage and prevents residual media from remaining, thereby eliminating contamination while maintaining position adaptability.
3Reliability
If end caps are screwed on to secure and seal the container, then the container is tightly closed, but small amounts of media can seep through valves into the caps causing contamination
Solution Approach 1:
The invention merges the sealing function into the spout structure itself, eliminating the need for separate end caps. The integrated design ensures that the sealing mechanism is positioned where it can effectively prevent media leakage without creating additional interfaces where seepage could occur.
4Ease of operation
If the spout valve is unlocked for pouring, then the media can flow out, but accidental opening and leakage can occur
Solution Approach 1:
The spout incorporates a dynamic locking mechanism that allows the user to easily switch between locked (sealed) and unlocked (pouring) states. The mechanism provides stable positioning in both states, ensuring accidental opening is prevented during transport while allowing simple activation during intended pouring operations.
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 controlled and spill-free pouring of free-flowing media, preventing contamination and ensuring the container remains sealed, even when tilted, by using a locking mechanism and compression spring to maintain the spout and ventilation valves in a closed position.
Implementation Method 1
A compression spring ensures that in the idle state, i.e. when the spout control is not actuated, the spout valve seals the spout and the ventilation valve is also closed.

AI summary
The invention relates to an arrangement for pouring free-flowing media out of a container. The arrangement contains a pour-out valve (3, 50) which can be specifically opened and closed by the user via an easy to operate actuating device (9), and thus allows a controlled pouring-out action. A pour-out tube (2) arranged in a pivotable manner on the container (1) makes it possible, depending on the position of the pivoted pour-out tube (2), to lock or unlock the pour-out valve (3, 50) using a blocking device. Locking the pour-out valve in the closed position prevents accidental opening of the pour-out valve (3, 50). The arrangement according to the invention also contains a venting valve (8), which can likewise be locked in the closed state. A compression spring ensures that, in the rest state, that is to say when the actuating device (9) is not actuated, the pour-out valve (3, 50) seals off the spout and the venting valve (8) is likewise closed.
