Rolled Foam Handle for Liquid Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container handles, such as those in GB 2 357 490 A, are prone to cutting into the hand during transport due to their design, leading to discomfort and potential injury.
Innovation Solution
A handle formed from a rolled-up flat material, which can be secured to a container using adhesive, providing a comfortable and ergonomic design that can be easily unrolled for access to an integrated instruction manual, and potentially made from elastic or shape-memory materials for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a plastic strap is used to form the handle, then the handle can be securely attached to the container, but the handle cuts into the hand during transport
Solution Approach 1:
The patent applies this principle by using a flexible foam material instead of a rigid plastic strap. The foam material provides cushioning and comfort against the hand while maintaining sufficient strength for attachment. The flexible nature of the foam allows it to conform to the hand shape, preventing cutting while still providing secure attachment to the container.
Solution Approach 2:
The patent applies this principle by combining the foam material with an adhesive layer to create a composite handle structure. The foam provides comfort and cushioning, while the adhesive ensures secure attachment to the container. This composite approach resolves the contradiction by integrating materials with complementary properties.
2Object-affected harmful factors
If the handle is made from a rolled-up flat material, then the volume of the handle is increased to prevent cutting, but the manufacturing complexity increases
Solution Approach 1:
The patent applies this principle by pre-rolling the foam material into a cylindrical shape before attachment to the container. This preliminary forming action creates the necessary volume and cushioning structure in advance, simplifying the subsequent attachment process and ensuring consistent handle geometry without complex manufacturing steps.
3Volume of stationary object
If the instruction manual is rolled up inside the roll, then space is saved and manufacturing is simplified, but the accessibility of the instruction manual is reduced
Solution Approach 1:
The patent applies this principle by designing the handle roll to be dynamically accessible. The instruction manual is integrated into the roll structure in a way that allows easy extraction and reinsertion without compromising the compact storage form factor. This dynamic design enables users to access the manual when needed while maintaining space efficiency during storage and transport.
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 solution enhances handling comfort by preventing the handle from cutting into the hand and allows for efficient recycling and space-saving storage, while also providing easy access to the instruction manual, reducing manufacturing costs and complexity.

AI summary
A device for the transport of a liquid includes a container for holding the liquid and a handle secured to the container. The handle is formed at least in portions by a roll of a rolled flat material. A handle for a container is manufactured by a method that can include a rolling step and a securing step.
