Self-locking subpackaging bottle with rotary locking mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing subpackaging equipment for liquid or emulsion products is not suitable for in-store use due to large size, inability to meet customer customization requirements, and lack of a self-locking mechanism to prevent accidental opening and waste.
Innovation Solution
A self-locking subpackaging bottle with a simple structure featuring a bottle body, a bottle cap with a snap joint, and an adapter with a rotating ring and fixing ring, which allows for secure locking and easy operation to facilitate customer-driven subpackaging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional switch is used for subpackaging, then the device is simple to operate, but the switch can be accidentally turned on causing perfume to flow out and waste
Solution Approach 1:
The switch mechanism transitions from a static on/off state to a dynamic two-position rotary system. The rotating cap with positioning structures (ridges and grooves) creates distinct locked and unlocked positions, making accidental activation unlikely while requiring deliberate user action to switch states.
Solution Approach 2:
The positioning structures (ridges on rotating cap, grooves on receiving cap) create preliminary mechanical resistance that prevents unintended switching. The system is designed to require deliberate rotational force to overcome these positioning features, thereby preventing accidental activation during normal handling.
2Manufacturing precision
If fixed volume canning equipment is used, then the subpackaging volume is consistent, but the equipment is large and not suitable for in-store use
Solution Approach 1:
The subpackaging system is segmented into a reusable main container and disposable sub-containers. The main container holds the bulk product, while individual sub-containers are filled to precise volumes using a simple pouring mechanism with flow control features, eliminating the need for large automated filling equipment.
Solution Approach 2:
The bottle incorporates self-regulating flow control features including flow restrictors and anti-siphoning mechanisms that automatically prevent overfilling. The system performs its own volume control function without requiring external monitoring or adjustment equipment.
