Container Cap With Incised Ring for Retention and Reattachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional container caps are easily separated from their containers, leading to issues such as loss, soiling, and environmental pollution, and existing solutions with complex designs require difficult manipulation to return to a closed state.
Innovation Solution
A cap design featuring incision lines and connection portions that allow the cap to remain connected to the container after opening, using injection molding or rotary cutting to form penetration lines with connecting pins and grooves, facilitating easy reattachment and reducing the risk of separation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cap is completely separated from the container upon opening, then the cap can be easily removed and accessed, but the cap becomes prone to being dropped, soiled, lost, and causing environmental pollution
Solution Approach 1:
The cap is divided into a main body and a disconnectable portion that can separate from the container opening upon opening, while remaining connected to the cap body through connection portions. This segmentation allows the cap to be easily accessed while maintaining connection to prevent loss and soiling.
Solution Approach 2:
The cap structure transitions from a fully connected state to a partially disconnected state upon opening. The disconnectable portion dynamically separates from the container opening but remains attached to the cap body through flexible connection portions, enabling both easy removal and retention.
2Reliability
If existing caps use complex connecting structures to remain attached to the container, then the cap can be prevented from being lost or soiled, but the design becomes complicated and requires difficult physical manipulation to return to a closed state
Solution Approach 1:
The connecting structure is segmented into multiple independent connection portions distributed around the cap. Each connection portion is a simple elastic element that independently maintains attachment, simplifying the overall structure while ensuring reliable retention and easy reattachment.
Solution Approach 2:
The connection portions are designed with elastic properties that allow them to deform and return to their original shape. This parameter change (elastic deformation) enables the cap to be easily attached and detached without complex manipulation, while maintaining reliable connection.
3Ease of manufacture
If the cap uses a simple separated design, then the manufacturing is simple and cost-effective, but the cap is easily lost, dropped, and causes environmental pollution
Solution Approach 1:
The cap is segmented into a main body and a disconnectable portion with simple connection portions, allowing for straightforward injection molding manufacturing while ensuring the cap remains attached to prevent loss and environmental pollution.
Solution Approach 2:
The connection portions serve multiple functions: they maintain attachment to prevent loss, allow easy opening and closing, and can be integrated into the injection molding process. This multi-functionality achieves environmental protection without significantly complicating manufacturing.

AI summary
A cap for a container is formed so that the cap has a top plate and a circular sidewall. Two opposite sides of the circular sidewall circularly connect to each other, one periphery of the circular sidewall connecting to one surface of the top plate forming a closed end, and another periphery of the circular sidewall at an opposite side of the closed end forms an opened end. Incisions are in the circular sidewall. The incisions form a ring member located at the opened end of the cap separated from a main body of the cap by a first incision and a second incision between the opened end of the main body and the ring member.
