Solution Overview

Problem

Existing solutions for closing and reopening open beverage containers, such as cans and bottles, are either impractical, costly, or not universal in their application, failing to effectively prevent insect and particle entry while consuming beverages and causing discomfort due to metal tabs.

Innovation Solution

A reversible, two-in-one closing device with a horizontal fan-shaped half-circular surface, featuring distinct markings and vertically protruding components, allows easy closure and reopening of both beverage cans and bottles, with alternative embodiments for different cap types, including a cap with a cone shape for secure sealing and a crescent-shaped edge for bottles of varying diameters.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If a protective cover is used for beverage can, then protection from insects and particles is improved, but the device becomes unpractical and costly to produce

Engineering Contradiction:
Improveprotection from insects and particlesVSAvoidcost to produce
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The closing device is divided into two functional sides: one side with a polygon component for can openings and the other side with a crescent-shaped edge for bottle openings. This segmentation allows a single device to serve multiple container types without requiring separate complex structures for each, reducing overall manufacturing cost while maintaining protection functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The closing device is designed as a universal solution that can close both beverage cans and bottles using the same device. The reversible design with different functional sides eliminates the need for separate protective covers for different container types, making it practical and cost-effective while providing continuous protection from insects and particles.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Duration of action of moving object

If a reusable cover with turning mechanism is used, then reopening capability is improved, but the device complexity increases

Engineering Contradiction:
Improvereopening capabilityVSAvoiddevice complexity
Core Design Contradiction:
Duration of action of moving objectVSDevice complexity

Solution Approach 1:

Instead of designing a complex turning mechanism that rotates the cover, the invention inverts the approach by having the opening tab of the can or the bottle cap pass through the closing device. The closing device remains stationary while the container opening moves through it, achieving reopening capability without complex mechanical mechanisms.

Inventive Principle:
Principle #13The other way round (Inversion)

Solution Approach 2:

The invention extracts the turning mechanism from the closing device itself and replaces it with a simple through-opening design. The opening tab or cap is extracted through the horizontal surface of the closing device, allowing the container to be reopened without requiring the closing device to rotate or have moving parts, thus reducing complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If the opening tab is left exposed, then ease of operation is improved, but harmful factors increase due to injury risk

Engineering Contradiction:
Improveease of openingVSAvoidinjury risk from metal tab
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The closing device acts as an intermediary between the user's mouth and the potentially harmful opening tab. By placing the closing device over the can opening with the tab passing through it, the device mediates the interaction, allowing the tab to remain functional for opening while preventing direct contact between the tab and the user's sensitive areas during consumption.

Inventive Principle:
Principle #24Intermediary (Mediator)

AI summary

The closing device for beverage container is a reversible device with a horizontal surface (5). One side of the closing device is a cover (1) which is meant for placement on the opening tab of a can in order to close the opening of the can, and the other side is a cover (3) to be placed on the opening of a bottle for closing it, whereas the cover of bottle opening, is designed to be used as two alternative embodiments: a cover to be slid on the bottle opening and a protruding element inserted into the bottle opening.
