Insulated beverage-container holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing beverage-container holders fail to provide continuous insulation, security against spillage, and convenience due to limitations in insulating properties and design, especially after the container is opened.
Innovation Solution
A dual-lid system with a primary lid and a secondary lid, where the primary lid has a deformable insulating disk and a flow-directing member, and the secondary lid forms a 360° seal when closed, combined with a handle for ease of use, to enclose and secure standard beverage cans.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a standard insulating beverage container holder is used, then some insulation is provided, but continuous insulation around every surface is not achieved and spillage prevention is insufficient
Solution Approach 1:
The lid structure is divided into two separate lids: a primary lid that provides initial sealing and insulation, and a secondary lid that provides additional sealing and spillage prevention. This segmentation allows each lid to perform specific functions, achieving continuous insulation and reliable spillage prevention that a single lid cannot provide.
Solution Approach 2:
The secondary lid is designed to nest over the primary lid, with the secondary lid's sealing surface engaging with the primary lid's outer surface. This nested configuration creates multiple sealing interfaces, ensuring continuous insulation around every surface of the beverage container and providing redundant spillage prevention.
2Ease of operation
If the beverage container is opened for drinking, then convenience is improved, but insulation is lost and contamination risk increases
Solution Approach 1:
The secondary lid is designed to be movable relative to the primary lid, allowing it to be lifted or removed for drinking while the primary lid remains in place. This dynamic configuration enables convenient access to the beverage while maintaining the primary lid's sealing and insulation functions, preventing total loss of insulation and reducing contamination risk.
3Ease of manufacture
If a simple construction is used, then manufacturing ease is improved, but secureness against spillage and movement is insufficient
Solution Approach 1:
The lids incorporate flexible sealing surfaces and deformable insulating material that can conform to the beverage container's shape. This flexibility ensures secure engagement and sealing without requiring complex rigid structures, achieving reliable spillage prevention and movement restriction while maintaining relatively simple construction suitable for manufacturing.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The dual-lid system provides continuous insulation, prevents spillage, and ensures convenience by maintaining a fluid-impermeable seal around the can, enhancing user experience with secure and efficient containment.
Implementation Method 1
a disk of resiliently-deformable insulating material on the underside of the main portion disposed to form a fluid-impermeable seal about the can opening
Implementation Method 2
disk of resiliently-deformable insulating material
Implementation Method 3
a fluid-impermeable secondary seal 360° around the drinking hole, such secondary seal being formed at points of frictional contact between the underside of the secondary lid and an adjacent upperside of the primary lid

AI summary
An insulating beverage-can holder including: a can-receiving cup; a primary lid that is secured to the upper edge of the cup and has (a) a main portion defining a drinking hole aligned with the can opening, (b) a disk of resiliently-deformable material on the underside of the main portion to form a seal about the can opening and having an aperture aligned with the drinking hole, and (c) a circumferential rim disposed to form a seal around the edge of the cup; and a secondary lid which is hinged to the primary lid at opposite sides of the main portion and is movable between a first position exposing the drinking hole and a second position closing the drinking hole and covering an area of the primary lid.
