Drink Container Venting Lid for Pressure Release Without Leakage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage containers with vent holes to prevent pressure-related leaks face issues with accurate vent blocking, leading to potential leakage, especially when carried in bags or during motion, and existing valve structures may fail, causing beverages to squirt or leak.
Innovation Solution
A beverage container design featuring a vent blocking portion that integrates a ventilation adjusting protruding portion and a cancellation operation to ensure effective pressure release, using an elastic slit portion that enlarges upon operation, preventing leaks and squirting without complex operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a vent hole is formed in the lid to release pressure, then beverage squirt through the straw is prevented, but beverage leakage occurs when the container is carried in a bag
Solution Approach 1:
The vent hole is designed with a movable blocking portion that can dynamically switch between open and closed states. The blocking portion is positioned to be movable between a first position where it blocks the vent hole and a second position where it opens the vent hole, allowing the system to adapt its ventilation state based on operational conditions
Solution Approach 2:
The system uses the user's own opening action of the outer lid to automatically trigger the vent opening. When the user opens the outer lid, the blocking portion is automatically moved to the second position through the engagement/disengagement mechanism, causing the vent to open without requiring separate user action
2Object-generated harmful factors
If a protruding portion is used to block the vent hole, then beverage leakage is prevented, but the protruding portion may be displaced and fail to accurately block the vent
Solution Approach 1:
The blocking portion is nested within the inner lid structure, specifically formed as an integrated part of the inner lid or as a component that fits within the inner lid's configuration. This nested arrangement ensures the blocking portion remains properly positioned and cannot be easily displaced
Solution Approach 2:
The blocking portion is merged with the engagement structure between the outer lid and inner lid. The blocking portion's position is tied to the engagement state, so that when the lids are properly engaged, the vent is reliably blocked, and when disengaged, the vent opens
3Object-generated harmful factors
If a valve structure is used for the vent hole, then beverage leakage is prevented, but the valve may malfunction and cause beverage squirt
Solution Approach 1:
The complex valve structure is extracted and replaced with a simpler blocking portion mechanism. Instead of using a valve that requires moving parts and sealing surfaces, the invention uses a geometric blocking approach where the blocking portion simply moves between two positions to either block or open the vent hole
Solution Approach 2:
The blocking portion is designed as a simple, robust component with no moving parts or精密 sealing requirements. This simple structure reduces the risk of malfunction and makes the component more reliable, even if it needs to be replaced
4Object-generated harmful factors
If the vent hole is blocked when carried, then beverage leakage is prevented, but pressure release is insufficient and causes beverage squirt
Solution Approach 1:
The system prepares the vent opening action to occur automatically when the user opens the outer lid. The blocking portion is positioned and configured so that the act of opening the outer lid automatically moves the blocking portion to the second position, opening the vent hole before the user completes the opening action
Solution Approach 2:
The engagement state of the outer lid and inner lid provides feedback that controls the vent state. When the lids are engaged (carrying state), the vent is blocked; when disengaged (opening state), the vent opens. This feedback mechanism ensures the vent responds automatically to the container's operational state
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 effectively and continuously releases pressure in the container, preventing leakage and squirting, while ensuring easy operation and reduced component count, thus enhancing the usability and reliability of the beverage container.
Implementation Method 1
the ventilation portion has a slit portion formed of an elastic member, and the ventilation adjusting protruding portion is configured to be able to enlarge the slit portion by moving a position of the ventilation adjusting protruding portion

AI summary
Provided is a beverage container which allows the pressure in the beverage container to be effectively and continuously released for a long period of time, thus effectively preventing, for example, possible leakage of the beverage in the beverage container. A beverage container 1 includes a container main body 2, an inner lid portion 3 that covers the container main body, a spout portion 8 which is formed on the inner lid portion and through which a beverage is discharged, a spout blocking portion 3a that blocks the spout portion, an outer lid portion 5 disposed so as to be able to engage with and disengage from the inner lid portion, a ventilation portion 10 that allows air to flow between the inside and the outside of the container main body, and a vent blocking portion 12h formed on the outer lid portion or the inner lid portion to block the ventilation portion when the outer lid portion is placed to close the inner lid portion. A cancellation operation portion 12c which cancels engagement between the outer lid portion and the inner lid portion is formed, and the beverage container 1 further includes a ventilation adjusting protruding portion 12i which projects from the vent blocking portion and which is configured to allow the ventilation portion to perform a ventilation operation on the basis of a cancelation operation by the cancellation operation portion.
