Stackable Hygienic Cover with Integrated Beverage Can Opener
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Beverage cans pose hygiene risks due to direct contact with contaminants during opening, especially in storage and transportation, where the existing opening systems are not protected, leading to potential contamination and health hazards, particularly for children.
Innovation Solution
A hygienic cover with a built-in can opener, designed to protect the upper portion of metal beverage cans, featuring a stackable and detachable design with handles, allowing easy opening while preventing direct contact with contaminants and maintaining the cans' stacking functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a protective cover is added to prevent contamination, then hygiene is improved, but device complexity increases
Solution Approach 1:
The patent combines the protective cover and can opener into a single integrated unit. The cover body incorporates an opening mechanism with a tab that directly interacts with the can lid, eliminating the need for separate protective and opening components. This merging reduces overall device complexity while maintaining hygiene protection.
Solution Approach 2:
The protective cover serves multiple functions: it protects the can opening area from contamination during storage and transport, and simultaneously functions as an opening mechanism through its integrated tab and lever system. This multi-functionality eliminates the need for separate protective covers and openers, reducing device complexity.
2Ease of operation
If an integrated opener mechanism is added to the cover, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The opening mechanism is designed to be self-operating through a lever arm that pivots on a fulcrum. When the tab is pulled, the lever automatically engages with the can lid and pries it open without requiring additional manual manipulation or complex mechanical components. The system uses the user's pulling force directly to accomplish the opening action.
Solution Approach 2:
Instead of having a complex mechanism that actively pushes the can open, the design inverts the approach by having a simple tab that, when pulled outward, passively engages a lever system that automatically pries the can lid open. The user pulls the tab away from the can, and the mechanical advantage of the lever does the rest, simplifying the operation.
3Ease of operation
If the cover is designed to be detachable and stackable, then ease of operation and storage are improved, but manufacturing precision requirements increase
Solution Approach 1:
The cover is designed as a detachable unit that can be separated from the can after opening, and multiple covers can be stacked together for storage. The attachment interface uses simple geometric features like ridges and grooves that allow for easy connection and disconnection without requiring high-precision manufacturing, facilitating both detachability and stackability.

AI summary
The present invention relates to a top lid for beverage cans, with an opener built into a hygienic cover. The hygienic cover is designed to cover the area around the opening part defined in the top lid, thereby protecting the contact portion of the lip of the top lid from atmospheric impurities and keeping the can clean during storage. The hygienic cover also has an opening system that presses on the opening part of the lid and breaks the part along the recessed seam when the cover is levered. The opening system has a reinforcement notch that improves the rigidity of the opening system, such that the opening system reliably breaks the opening part of the lid without failure, even if a high pressure is acting on the inner surface of the opening part. The configuration and arrangement of the notch in the opening system can be changed freely according to the design conditions of the can, or the internal pressure acting on the opening part and the size of the can. The hygienic cover also includes a handle that can be operated by the user with the fingers in order to lift same. This handle makes it easy for a user to grip and handle the cover while lifting said cover in order to open the top lid of the beverage can.
