Silicone Rubber Can Cap with Inner Band for Water-Proof Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current beverage caps are made of plastic and lack water-proof and water-resistant properties, making them unsuitable for protecting the contents of an open-mouth container from external contaminants.
Innovation Solution
A reusable silicone rubber cap with a thin attachable inner band that wraps around the can, providing a water-proof and insect-proof seal for beverage cans and boxes, allowing easy access to the contents without removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a plastic cap is used to cover the beverage can, then the cap provides a basic lid function, but it fails to provide water-proof and water-resistant protection against external contaminants
Solution Approach 1:
The patent changes the material parameter from standard plastic to silicone rubber, which provides superior water-proof and water-resistant properties. This material substitution directly addresses the failure of plastic caps to prevent contaminant penetration while maintaining the basic lid function.
Solution Approach 2:
The invention uses a composite structure combining an inner band and an outer cap made of silicone rubber. This composite design integrates the securing function of the band with the protective sealing function of the cap, achieving both retention and contamination prevention.
2Ease of operation
If the cap is designed to be easily removable for access, then convenience is improved, but the cap tends to be misplaced or lost
Solution Approach 1:
The cap system is divided into two functional segments: an inner band that remains attached to the can for retention, and an outer cap that can be easily removed for access. This segmentation allows the cap to provide both secure attachment and convenient accessibility without being misplaced.
Solution Approach 2:
The inner band acts as an intermediary element between the can and the outer cap. It provides the attachment mechanism that secures the cap system to the can, enabling easy removal and reattachment of the outer cap while preventing loss of the entire cap assembly.
3Device complexity
If a traditional cap design is used, then the structure is simple, but it cannot maintain sanitation precautions during beverage consumption
Solution Approach 1:
The silicone rubber material forms a flexible shell that creates an effective seal between the cap and the can opening. This flexible sealing structure maintains sanitation by preventing contaminant ingress while allowing for easy deformation during placement and removal, keeping the structure relatively simple.

AI summary
Provided herein is a re-usable device that would allow for the export of, or consumption of liquid without having to remove the device from the can such as the aluminum beverage can and that would also seal the liquid inside a beverage can. A water-resistant or water-proof, insect-proof, dirt-proof synthetic cap is provided that is to be attached to the lip area of the open mouth of can or other open mouth container, such as metal, plastic or an aluminum beverage can.
