Insulated Container Lid With Rotatable Pressure Vent
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers can experience high internal pressure due to stored liquids or foods, leading to potential safety issues and the need for effective pressure relief mechanisms.
Innovation Solution
The design incorporates a multi-part lid with a venting system featuring a rotatable vent plug that can be positioned between closed, venting, and disengaged states, allowing for controlled pressure equalization through a threaded interface and insulating features to maintain temperature stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed container is used to store liquids or foods, then the container maintains its contents and provides insulation, but high internal pressure may build up causing safety issues
Solution Approach 1:
The vent plug is designed to be rotatable between multiple positions (closed, venting, disengaged) allowing the container to dynamically adjust its pressure relief state based on operational needs, resolving the contradiction between maintaining seal integrity and allowing pressure escape
Solution Approach 2:
The vent plug acts as an intermediary mechanism between the sealed container and the external environment, providing controlled pressure equalization while maintaining the overall sealed structure, thus preserving both insulation and safety
2Object-affected harmful factors
If a venting mechanism is added to relieve pressure, then safety is improved, but the container structure becomes more complex
Solution Approach 1:
The lid is segmented into multiple functional portions (upper lid portion, lower lid portion, bottom lid cap) with the vent plug as a separate rotatable component, allowing the pressure relief function to be isolated and controlled without complicating the entire lid structure
Solution Approach 2:
The vent plug serves multiple functions: it seals the vent opening when closed, allows pressure equalization when in venting position, and can be completely removed when disengaged, providing versatile pressure management with a single component
3Reliability
If a multi-part lid with venting system is used, then pressure management and insulation are improved, but the device complexity increases
Solution Approach 1:
The vent plug is nested within the multi-part lid assembly, fitting into the vent opening formed by the upper lid portion, lower lid portion, and bottom lid cap, allowing compact integration of the venting mechanism within the existing lid structure without proportionally increasing overall complexity
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 solution effectively manages pressure within the container while maintaining insulation, ensuring safety and preserving the contents' temperature, enhancing user convenience and safety.
Implementation Method 1
an insulating puck engaged between the upper lid portion and the lower lid portion
Implementation Method 2
The sidewall structure may comprise a sealed vacuum cavity between an inner wall and an outer wall
Implementation Method 3
a vent opening extending through each of the upper lid portion, the insulating puck, the lower lid portion, and the bottom lid cap; and a removable vent plug configured to vent air through the vent opening

AI summary
An insulated container having a canister can be sealed by a lid structure. The lid structure can be a multi-part insulated lid. The lid can include a vent configured to vent air from inside the canister. In addition, the container may be part of a container kit or container system where one or more inner containers, are nested and secured within the insulated container.
