Bubble Liquid Bottle Pressure-Relief Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional bubble liquid bottles face issues with the pressure-relief function failing due to the ring being cut off by the outlet channel after repeated use, leading to a loss of efficacy and safety concerns.
Innovation Solution
A bubble liquid bottle design featuring a ring that sleeves a stopper, with the stopper movably disposed in a communication channel to prevent cutting, and an elastic member to block communication between the outlet and communication openings, ensuring the pressure-relief function remains effective over multiple uses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ring is disposed under the outlet channel to block communication between the outlet channel and straw opening for hermetic purpose, then the pressure-relief function is achieved, but the ring may be cut off by the outlet channel after repeated use, causing loss of efficacy and safety concerns
Solution Approach 1:
The invention divides the sealing function into two separate components: the stopper (which blocks communication) and the ring (which prevents overflow). This segmentation allows the stopper to be positioned in the communication channel away from the outlet channel corner edge, eliminating the cutting problem while maintaining both hermetic sealing and pressure-relief functions over extended service life
Solution Approach 2:
The stopper acts as an intermediary component between the outlet channel and straw opening, performing the blocking function that was previously attempted by the ring. This intermediary structure is specifically designed to be cut-resistant and positioned to avoid contact with the outlet channel edge, thereby solving the durability issue
2Productivity
If the ring moves with the piston to enable pressure relief, then the pressure-relief effect is generated, but the ring is subjected to cutting force from the outlet channel corner edge, reducing its structural integrity
Solution Approach 1:
The invention separates the pressure-relief mechanism (piston with stopper) from the overflow-prevention function (ring). The stopper moves with the piston to enable pressure relief, while the ring remains stationary or moves minimally, avoiding contact with the outlet channel corner edge and preserving its structural integrity
Solution Approach 2:
The invention extracts the blocking function from the ring and assigns it to the stopper. This allows the ring to focus solely on preventing liquid overflow without being subjected to cutting forces, thereby maintaining its strength and structural integrity over multiple pressure-relief operations
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 ensures the pressure-relief device functions consistently, enhancing the safety and longevity of the bubble liquid bottle by preventing the ring from being cut off during pressure-relief operations.
Implementation Method 1
The elastic member is disposed in the communication channel and abuts against the stopper for providing an elastic force to drive the stopper to block communication between the outlet channel and the communication opening
Implementation Method 2
When the internal pressure of the bottle body is greater than a first predetermined value, the stopper is moved upward by the internal pressure of the bottle body to make the outlet channel communicated with the communication opening
Implementation Method 3
make gas provided by the gas filling bottle enter the bottle body via the communication opening and then dissolve in the liquid contained in the bottle body to generate a bubble liquid

AI summary
A bubble liquid bottle (10) includes a bottle body (12), a pad (14) covering a mouth (20) of the bottle body (12), a straw (16) connected to a communication opening (15) of the pad (14) and inserted into the bottle body (12), and a head (18). The head (18) is disposed on the mouth (20) and includes a main body (24) having outlet, inlet, and communication channels (30, 32, 34), a handle (28), and a pressure-relief device (26) disposed in the communication channel (34) and including a stopper (36), an elastic member (38) for driving the stopper (36) to block communication between the outlet channel (30) and the communication opening (15), and a ring (40) located above the outlet channel (30) and sleeving the stopper (36). The handle (28) is pivoted to the main body (24) and inserted into the stopper (36) for moving the stopper (36) upward.
