Closure Device With Intermediate Degassing Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closure devices for containers, particularly bottles, often experience sudden pressure compensation when opened, leading to undesirable flow of contents due to pressure differences, especially when carbonated liquids are involved or when altitudes change.
Innovation Solution
A closure device with a defined intermediate position that includes a degassing channel, which opens during pressure compensation, allowing controlled pressure release without immediate medium dispensing, and requires increased force or a change in movement direction to transition from closed to open, ensuring minimal content loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lid is opened directly from the completely closed position to the completely open position, then the opening operation is simple and quick, but sudden pressure compensation causes medium to flow out undesirably
Solution Approach 1:
The opening operation is segmented into two distinct phases: first opening to an intermediate position where the degassing channel opens for pressure equalization, then opening further to the fully open position for dispensing. This segmentation prevents sudden pressure compensation by controlling the sequence of channel openings.
Solution Approach 2:
The degassing channel opens before the dispensing opening during the opening process. This preliminary action allows pressure compensation to occur first, equalizing the pressure difference before the medium can flow out through the dispensing opening, thereby preventing medium loss.
2Loss of substance
If a degassing channel is introduced to enable pressure compensation, then medium loss is reduced, but the device structure becomes more complex
Solution Approach 1:
The lid structure serves multiple functions: it acts as both a sealing element for the dispensing opening and a control mechanism for the degassing channel. The same lid movement that opens the dispensing opening also controls the degassing channel opening sequence, eliminating the need for separate dedicated components and reducing overall structural complexity.
3Productivity
If the lid is designed to open directly to the fully open position, then the dispensing operation is efficient, but pressure compensation occurs suddenly causing product flow out
Solution Approach 1:
The lid is designed with dynamic positioning capability, allowing it to rest stably at both the intermediate position (where degassing occurs) and the fully open position (where dispensing occurs). This dynamic design enables the system to adapt to different operational phases while maintaining reliability in pressure control during the intermediate state.
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 device effectively prevents or significantly reduces medium loss during opening by allowing controlled pressure compensation in the intermediate position, ensuring the contents remain contained until fully opened, with the user experiencing minimal disruption and no need for caution.
Implementation Method 1
the closure device has at least one degassing channel, which is closed off in the completely closed position of the lid and which, in the intermediate position of the lid, enables a pressure compensation between the side of the closure device which is to be brought to face the container interior and the ambiance

AI summary
The invention relates to a closure device for a container, comprising a base element that can be attached to an opening of the container, and a lid, such as a cover, that can be disposed back and forth between a completely closed, and a completely open, position, wherein the closure device is configured such that the lid has at least one defined intermediate position between the completely closed and the completely open positions, and wherein the closure device has at least one degassing channel, which is sealed off in the completely closed position of the lid and enables pressure compensation between a side of the closure device facing the interior of the container and the surrounding area in the intermediate position of the lid.
