Venting device, lid, and container comprising lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional venting devices for containers, particularly children's drinking cups, often cause liquid to spray out when the lid is opened due to pressure differences, and their complex structures complicate lid operation and cleaning.
Innovation Solution
A venting device with an air channel and a rotary venting rod that rotates to provide vented and sealed states, featuring a concave venting slot for easy operation and disassembly, facilitating maintenance and cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional venting device with complex linkage mechanism is used, then pressure equalization function is achieved, but the device structure becomes complex and difficult to operate
Solution Approach 1:
The venting device is segmented into independent functional components: a vent hole in the lid, a valve member with valve body and valve core, and a separate actuating mechanism. This segmentation allows each component to be optimized independently and simplifies the overall structure by eliminating complex linkages between components.
Solution Approach 2:
The valve core is extracted as a separate, movable component from the valve body. This extraction allows the valve core to be independently actuated by a simple pressing motion, eliminating the need for complex linkage mechanisms while maintaining the pressure equalization function.
2Reliability
If a conventional venting device with integrated cleaning-resistant structure is used, then sealing function is improved, but cleaning accessibility is reduced
Solution Approach 1:
The valve assembly is segmented into detachable components (valve body, valve core, and lid) that can be separated for cleaning. This segmentation maintains sealing integrity during operation while providing easy access to all surfaces for thorough cleaning and maintenance.
3Ease of operation
If the lid structure is simplified for easy operation, then ease of operation is improved, but pressure equalization control precision is reduced
Solution Approach 1:
The valve core acts as an intermediary between the simple pressing action and the pressure equalization function. This intermediary component translates the simple pressing motion into precise control of the vent hole opening, maintaining control precision while preserving operational simplicity.

AI summary
A venting device comprises an air channel and a rotary venting rod, wherein: the air channel comprises a first end facing an outer surface of the rotary venting rod and a second end away from the rotary venting rod; the outer surface of the rotary venting rod is provided with a recessed venting slot in fluid communication with ambient air, about which the rotary venting rod may be rotated about a rotation axis extending longitudinally thereof to provide a vented state and a sealed state. In the vented state, at least a portion of the venting slot of the rotary venting rod is in fluid communication with the air channel and thereby brings the air channel into fluid communication with ambient air via the venting slot. In the sealed state, the venting slot of the rotary venting rod is not in fluid communication with the air channel and the first end of the air channel is sealed by the outer surface of the rotating vent rod. The venting device of the present invention is easy to manufacture and assemble. The present invention also relates to a lid comprising the above-mentioned venting device and a container comprising the lid.
