Bottle Cap Air Bubble Removal for Ultrapure Water
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sample containers fail to effectively remove residual air or bubbles from the interior, leading to contamination of ultrapure water during storage, which degrades the quality of high-purity water over time, especially when exposed to the atmosphere.
Innovation Solution
A bottle cap design featuring a cap body with a cover plate, cylinder part, and a stopper member supported by a support structure, including an annular guiding plate and sealing part, which facilitates the removal of air or bubbles through a spiral female threaded portion and elastic sealing elements, ensuring airtightness and preventing contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional bottle caps are used to seal ultrapure water, then the container can be closed and stored, but air bubbles remain inside the container causing contamination
Solution Approach 1:
The invention extracts the air bubble removal function from the conventional sealing cap by adding a dedicated stopper member with sealing part and guiding plate structure. This separate component actively removes air bubbles from the container interior while the main cap body provides sealing, dividing the functions of sealing and air removal into distinct structural elements.
Solution Approach 2:
The stopper member is designed to be inserted into the container before final sealing, performing the air bubble removal action in advance. The inclined guiding plate and sealing part work together to expel air bubbles from the interior sidewalls before the cap is fully tightened, preventing contamination before it occurs during storage.
2Object-affected harmful factors
If the bottle cap is designed with additional components for air removal, then air bubbles can be removed effectively, but the device complexity increases
Solution Approach 1:
The invention merges the air removal function with the sealing cap by integrating the stopper member directly into the cap body structure. The support structure connects the sealing part to the cover plate, combining multiple functions (sealing, air removal, structural support) into a single integrated component rather than separate parts.
Solution Approach 2:
The stopper member serves multiple functions: it seals the container opening, removes air bubbles through the inclined guiding plate, and provides structural support via the support structure. This multi-functional design achieves air bubble removal without requiring additional separate components, maintaining simplicity while enhancing functionality.

AI summary
A bottle cap is disclosed. The bottle cap includes a cap body having a cover plate and a cylinder part integral with the cover plate. A stopper member protrudes from an inner surface of the cover plate. The stopper member includes a sealing part supported by a support structure integral with the cover plate. An annular guiding plate protrudes from a sidewall surface of the cylinder part and is inclined toward the stopper member to engage with the sealing part.
