Wide-Mouth Container Closure Venting for Quiet Pressure Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing closures for wide-mouth containers, particularly for carbonated beverages, often produce a loud popping sound when opened due to sudden seal release and can unintentionally detach, leading to unpleasant liquid spillage.
Innovation Solution
A container and closure design featuring parallel movement of the closure relative to the container, with a seal that forms a fluid-tight seal against the side surface, utilizing interrupted and continuous threads to manage pressure and prevent sudden seal release, and incorporating grooves for venting high-pressure gases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the seal contacts the side surface of the container to seal the opening, then a fluid-tight seal is achieved, but the seal may move suddenly upon removal causing a loud popping sound
Solution Approach 1:
The thread portions of the container are configured to provide at least one interrupted thread formed from separate thread portions, while the closure provides at least one continuous thread. This segmentation of the threading system allows controlled engagement and disengagement that prevents sudden seal release and associated popping sounds while maintaining fluid-tight sealing.
Solution Approach 2:
The closure is configured to move parallel to the opening axis during rotation, creating a dynamic engagement path. This parallel movement allows the seal to gradually disengage from the container side surface rather than suddenly releasing, eliminating the loud popping sound while maintaining sealing integrity throughout the opening process.
2Reliability
If the closure is designed to securely close the container under pressure, then secure sealing is achieved, but the closure may unintentionally detach when knocked
Solution Approach 1:
The interrupted thread configuration on the container with corresponding continuous threads on the closure creates multiple engagement points distributed around the circumference. This segmented threading provides both secure holding under pressure and controlled resistance to accidental detachment, as the interrupted nature requires deliberate rotational force to disengage.
Solution Approach 2:
The thread portions are configured to define movement of the closure in a direction parallel to the opening axis during rotation. This curved engagement path creates a mechanical advantage that secures the closure under pressure while requiring intentional user action to overcome the engagement and remove the closure, preventing accidental detachment.
3Reliability
If the seal is compressed between the container and closure, then a fluid-tight seal is formed, but the seal may release suddenly causing liquid spillage
Solution Approach 1:
The closure movement is configured to travel parallel to the opening axis during rotation, creating a gradual disengagement path for the seal. This dynamic movement allows the seal to progressively release from compression between the container and closure, preventing sudden liquid spillage while maintaining fluid-tight sealing during normal operation.
Solution Approach 2:
The interrupted thread configuration allows preliminary controlled engagement and disengagement phases. During removal, the seal can gradually decompress through the interrupted thread mechanism before complete separation, preventing sudden liquid release while ensuring fluid-tight sealing when closed.
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 design provides a quiet and controlled opening experience, preventing liquid spillage and ensuring a secure seal, enhancing user satisfaction and safety.
Implementation Method 1
the closure has a seal, configured to be able to form a fluid-tight seal against the side surface of the container
Implementation Method 2
the container and closure have respective thread portions that cooperate to define movement of the closure relative to the container in a direction parallel to the opening axis as the closure rotates about the opening axis relative to the container
Implementation Method 3
incorporating grooves for venting high-pressure gases

AI summary
A container a side surface and a rim that defines an opening and an axis; a closure for the container; the container and closure having cooperating threads to move the closure axially as it is rotated; the closure having a seal against the side surface of the container; the thread portions of the container and closure are configured such that, as the closure rotates relative to the container, the seal moves parallel to the axis contacting three regions on the side surface of the container: a first region, configured such that, as the seal is moved across the region, the seal changes between states in which it is uncompressed and compressed between the container and closure; a second region, where the fluid bypasses part of the seal; and a third region where the seal forms a fluid-tight seal between the side surface and the closure.
