Container Lip Sliding Seal for Carbonated Beverage Pressure Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When opening a container of carbonated beverage, the high air pressure inside can cause the liquid to spray out, leading to waste and discomfort.
Innovation Solution
A container lid design featuring a lip body, an inner ring, and a first sealing ring, where the inner ring is slidably connected to the lip body, and the first sealing ring is fixedly connected to the lip body, allowing for controlled gas release when opening the lid.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container lid is opened quickly, then the operation is fast and convenient, but the liquid sprays out due to high internal pressure
Solution Approach 1:
The sealing ring is designed to automatically separate from the sealing surface during the opening process before the lid is fully opened. This preliminary separation action allows gas to escape first, reducing internal pressure, and prevents liquid from spraying out when the lid is opened quickly
Solution Approach 2:
The sealing ring is made movable relative to the lid body through a sliding connection with the inner ring. This dynamic design allows the sealing ring to automatically move to a non-sealing position during opening, enabling controlled gas release while maintaining sealing during closing, thus resolving the contradiction between fast opening and preventing liquid spray
2Device complexity
If a traditional fixed sealing structure is used, then the structure is simple, but gas pressure cannot be controlled and liquid sprays out
Solution Approach 1:
The sealing structure transitions from a fixed design to a dynamic one where the sealing ring can slide along the inner ring. This allows the sealing contact to be automatically adjusted during opening and closing operations, enabling controlled gas pressure release while maintaining relatively simple overall structure
Solution Approach 2:
The sealing system is divided into separate components: the sealing ring mounted on the lid body and the inner ring with step surface on the container. This segmentation allows independent movement of the sealing ring relative to the container, enabling controlled gas release while keeping the overall structure manageable
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 allows for controlled gas release when opening the container lid, reducing pressure and preventing liquid from spraying out, thus minimizing waste and user discomfort.
Implementation Method 1
the high air pressure inside can cause the liquid to spray out... allowing for controlled gas release when opening the lid... reducing pressure

AI summary
A container lip and a container having the same are provided. A container lip includes a lip body, an inner ring and a first sealing ring. The inner ring disposed around an outer periphery side of the lip body. The inner ring is slidably connected to the lip body. The first sealing ring is disposed between the inner ring and the lip body. The first sealing ring is fixedly connected to the lip body. A side of the inner ring towards the lip body is provided with a first step surface. When the container lip is in a closed state, the first sealing ring is in contact with the first step surface. When the container lip is in an opened state, the first sealing ring is separated from the first step surface.
