Brush Glue Bottle Sealing Structure for Leak Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional glue bottles suffer from poor sealing performance due to direct threaded or snap-fit connections, leading to leakage and volatilization of glue, resulting in residue formation.
Innovation Solution
A glue bottle design featuring a detachable lid with a connecting handle and brush, incorporating a groove structure at the bottle mouth and a protruding annular structure on the lid, along with a nested inner and outer bottle body configuration and snap-fit connections to enhance sealing and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If direct threaded or snap-fit connection is used between lid and bottle, then device complexity is reduced, but sealing performance deteriorates leading to leakage and volatilization
Solution Approach 1:
The connection structure is segmented into multiple functional components: the groove structure on the bottle mouth, the protruding annular structure on the lid, and the snap-fit connection elements. This segmentation allows each component to perform its specific function (sealing, positioning, locking) independently, resolving the contradiction between simplicity and sealing performance
Solution Approach 2:
The protruding annular structure acts as an intermediary element between the lid and bottle. It fits into the groove structure to create a sealing interface, mediating the connection between the two components and preventing direct contact that would cause leakage
2Ease of manufacture
If simple direct connection is used, then ease of manufacture is improved, but glue volatilization and residue formation increase
Solution Approach 1:
The groove and protruding annular structure are designed to preemptively prevent glue contact with the connection interface before volatilization can occur. The sealing structure creates a barrier that stops glue from reaching areas where it would evaporate and form residue, addressing the harmful effect before it happens

AI summary
The present application provides a glue bottle with a brush to address the issue of poor sealing performance in conventional glue bottles. The glue bottle includes a lid and a bottle, in which a side of the lid is detachably connected to the bottle, the lid is internally provided with a connecting handle, an end portion of the connecting handle is provided with the brush; a bottle mouth end surface of the bottle is provided with a groove structure; and the lid is internally provided with a protruding annular structure corresponding to the groove structure of the bottle mouth, thereby addressing leakage at the bottle mouth and enhancing the sealing performance when the lid is connected to the bottle.
