Packaging Device Cover Nesting in Bottle Neck
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging devices for dispensing products often have covers that can become soiled, damaged, or scratched due to exposure, compromising their functionality and aesthetics.
Innovation Solution
A packaging device design where the cover is positioned within the neck of the bottle, protected from external damage, and secured using methods such as ultraviolet radiation bonding, hot-melt adhesion, or metallized adhesive plates, ensuring the cover remains intact and functional throughout the product's dispensing process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover is positioned outside the bottle neck for easy access, then the dispensing operation is simplified, but the cover becomes susceptible to soiling, damage, and scratches
Solution Approach 1:
The cover is positioned inside the bottle neck, nested within the protective structure of the neck opening. This nesting arrangement protects the cover from external harmful factors while maintaining functionality through the defined opening in the cover that allows access to the dispensing mechanism.
Solution Approach 2:
The cover is designed with a specific opening segment that separates the protective function from the access function. The opening allows the dispensing mechanism to remain accessible while the rest of the cover surface remains protected inside the neck, effectively segmenting the cover into protected and accessible zones.
2Reliability
If the cover is positioned inside the bottle neck for protection, then resistance to soiling and damage is improved, but the structure becomes more complex
Solution Approach 1:
The cover is merged with the neck structure by fixing it to the inner wall of the neck, creating an integrated assembly. This merging reduces the number of separate components and simplifies the overall structure while maintaining the protective positioning of the cover inside the neck.
Solution Approach 2:
The cover is pre-positioned and fixed inside the neck during manufacturing, rather than being attached later. This preliminary action ensures proper positioning and integration, reducing assembly complexity and ensuring the cover is already protected when the product is filled and sealed.
3Reliability
If sealing elements are added to secure the cover inside the neck, then the cover fixation is improved, but the device complexity increases
Solution Approach 1:
A flexible sealing element is used to secure the cover to the inner wall of the neck. The flexibility of the seal allows it to conform to the neck's inner surface and accommodate slight variations in positioning, providing reliable fixation without requiring complex rigid mounting structures or multiple fastening components.

Function Achieved in This Case
The solution effectively prevents the cover from being soiled, damaged, or scratched, maintaining its integrity and the overall appearance of the packaging device, while allowing for easy access to the dispensing mechanism.
Implementation Method 1
a washer-like seal positioned between the cover and the bottle
Implementation Method 2
the cover is fixed to any of the parts of the packaging device by bonding with ultraviolet radiation
