Squeeze-Actuated Vent Valve for Slanted-Wall Buckets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cover arrangements for containers with slanted sidewalls are limited in their ability to effectively vent air, leading to oxidation and staleness of contents, as they require cumbersome handle rotation and are not designed to conform to tapered walls, making them inefficient for deep receptacles like 5-gallon buckets.
Innovation Solution
A squeeze-actuated vent valve arrangement with a deflectable outer seal that can be easily operated by pushing down inside the container, eliminating the need for handle rotation and providing a secure seal on slanted surfaces, allowing for efficient air venting without interfering with contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional vent handle arrangement is used, then the venting function is provided, but the operation becomes cumbersome due to handle rotation requirements and inability to conform to slanted sidewalls
Solution Approach 1:
The patent inverts the conventional venting mechanism by replacing the handle rotation operation with a push-down action. The squeeze-actuated vent valve arrangement allows the vent handle to be operated by simply pushing down inside the container, eliminating the need for rotational movement and complex handle mechanisms.
Solution Approach 2:
The patent changes the operational parameter from rotational motion to linear push-down motion. The deflectable outer seal arrangement is designed to deflect and conform to slanted sidewalls when pushed down, changing the geometric parameter adaptation from fixed to variable based on container shape.
2Adaptability or versatility
If a conventional cover arrangement is used, then the cover can enclose contents, but it cannot effectively conform to slanted sidewalls of deep receptacles
Solution Approach 1:
The patent introduces dynamics to the seal arrangement by making the outer seal deflectable. The deflectable outer seal arrangement can dynamically adapt its shape to conform to slanted sidewalls when pushed down, rather than maintaining a fixed rigid structure that cannot accommodate varying container geometries.
Solution Approach 2:
The patent employs a flexible seal arrangement that can bend and deflect to match the contour of slanted sidewalls. The deflectable outer seal acts as a flexible element that deforms under push-down force to create effective sealing contact with irregular or tapered container surfaces.
3Reliability
If air venting is not effectively provided, then the container can be easily sealed, but the contents become oxidized and stale due to trapped air
Solution Approach 1:
The patent implements preliminary action by providing an automatic venting mechanism that allows air to escape before the container is fully sealed. The squeeze-actuated vent valve arrangement enables users to vent air by simply pushing down, and the system automatically closes after venting, preventing oxidation before it can affect the contents.

AI summary
Aspects and techniques of the present disclosure relate to an internal cover/vent handle arrangement, in association with a container, such as a 5 gallon bucket with a slanted sidewall for evacuating air volume above stored material. The disclosure relates to a squeeze-actuated vent valve arrangement arranged and configured to be easily operated even while deeply recessed in the bucket. The disclosure also relates to a deflectable outer seal arrangement configured to seal against a slanted sidewall of a bucket.
