Self-Venting Silicone Container Lid With Tear-Contained Pressure Relief
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional food storage containers are not dishwasher and microwave safe, prone to breaking, require manual venting during cooking, and fail to maintain food freshness due to inadequate sealing and gas venting.
Innovation Solution
A self-venting food storage container made of silicone with a venting aperture and a barrier to prevent tearing, allowing automatic pressure relief and maintaining a sealed environment while being dishwasher and microwave safe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional plastic or glass containers are used to seal food, then food freshness is maintained through sealing, but pressure build-up during cooking causes safety hazards and mess
Solution Approach 1:
The lid incorporates a venting aperture that functions as a controlled porous opening, allowing pressure and steam to escape during cooking while maintaining a sealed environment for food freshness storage. The aperture enables selective permeability - sealed during storage but venting during heating
Solution Approach 2:
The venting aperture provides dynamic pressure relief functionality that adapts to different usage conditions. During microwave cooking, the aperture opens to release pressure automatically, while during normal storage it remains sealed to maintain freshness, creating a dynamic sealing system
2Device complexity
If aluminum foil or plastic wrap is used to cover food, then the container structure remains simple, but proper sealing to maintain freshness is not achieved
Solution Approach 1:
The venting aperture is integrated directly into the lid structure, merging the sealing function and pressure relief function into a single unified component. This eliminates the need for separate foils or wraps while providing both sealing and controlled venting capabilities
3Ease of operation
If the venting aperture is made of thin silicone material to facilitate venting, then pressure relief is improved, but the lid becomes susceptible to tearing
Solution Approach 1:
The barrier creates a local quality distinction in the lid structure - the venting aperture area uses thinner material for efficient pressure relief, while the barrier provides localized reinforcement at the critical stress point, and the rest of the lid maintains sufficient thickness for overall structural integrity
Solution Approach 2:
The barrier acts as a preventive reinforcement structure that cushions against potential tearing propagation. By placing the barrier beforehand at the aperture location, it prevents small tears from spreading and compromising the entire lid structure
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 silicone container effectively vents gases, prevents breakage, and ensures safe microwave use, while maintaining food freshness and ease of cleaning.
Implementation Method 1
The container includes a venting aperture, such as on the lid, which is configured to release pressure (e.g., during storage or cooking) that may build-up in the sealed food storage container
Implementation Method 2
The venting aperture is defined by a barrier configured to stop tearing of the lid in the event the venting aperture tears or rips
Data Source
AI summary
The present invention relates generally to self-venting food storage containers that release pressure build up inside the sealed container during storage or cooking. The silicone food storage container includes a venting aperture configured to release pressure build-up from within the container. The venting aperture is defined by a barrier and includes an area of silicone that is thinner than the thickness of the material of the lid, so any tear in the venting aperture will not tear past the circumference of the barrier. The silicone food storage container is also dishwasher safe, microwave safe, and, for the most part, unbreakable.
