Polygonal Coating Container Lid with Integrated Handle and Pour Spout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional metal paint cans are difficult to open and close, often requiring tools and can be hazardous, leading to potential injury, damage, or spillage of coating materials.
Innovation Solution
A storage container with a polygonal shape, featuring a corrugated cardboard or similar material body, an end cap with a collar and pour spout, and a lid with a carrying handle, allowing for easy opening, pouring, and stacking without the need for external tools or handles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a metal can with a metal removable lid is used, then the container can store coating materials, but the lid removal and replacement becomes difficult and hazardous requiring tools
Solution Approach 1:
The lid assembly is segmented into multiple functional components: a lid body, a integrated handle, and a pour spout. This segmentation allows each component to perform its specific function independently, making the lid easy to grip, remove, and use for pouring without requiring external tools
Solution Approach 2:
The handle and pour spout are merged into a single integrated lid structure. The handle is formed as part of the lid body, and the pour spout is integrated at one end of the lid, eliminating the need for separate components and simplifying the opening and pouring operations
2Ease of operation
If a bail made from steel wire is mounted on the container, then the container can be moved and carried, but the container shape is limited to circular shape
Solution Approach 1:
The carrying handle is merged with the lid structure, forming an integrated component. This eliminates the need for a separate bail attached to the container body, allowing the container to be carried by the lid handle regardless of the container's shape
Solution Approach 2:
The handle extends in a direction perpendicular to the longitudinal axis of the container, providing a carrying interface that is independent of the container's shape. This dimensional change allows any container shape to be portable
3Reliability
If a prying tool or screwdriver is used to remove the lid, then the lid can be opened, but the task becomes more difficult and time-consuming
Solution Approach 1:
The lid is designed with an integrated handle that enables users to grip and remove the lid directly by hand without requiring external prying tools or screwdrivers. The self-contained design eliminates the need for additional tools, reducing task complexity and time
4Reliability
If a hammer or mallet is used to reseat the lid, then the lid can be secured, but physical injury or damage may occur
Solution Approach 1:
The lid assembly is designed to be secured through controlled deformation of the container body itself, which acts as the securing mechanism. The user presses the lid into place using hand pressure, and the container body's deformation provides the securing force, eliminating the need for hammers or mallets and reducing injury risk

AI summary
Provided is a storage container for storing a coating material including a container body having first and second ends, a receptacle disposed within the container body, an end cap attached to the container body at the first end and including a base and a collar projecting upward from the base in a first direction that defines a through passage in communication with the receptacle, and a lid removably coupled to the collar of the end cap, the lid including a carrying handle extending in a second direction perpendicular to the first direction and a pour spout adjacent an edge of the lid that defines a through passage in communication with the through passage of collar and the receptacle.
