Plastic Container Body with Metal Pop-Top Lid
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Metal containers with easy-open lids are difficult to design and manufacture due to the limitations of shaping metal, making it costly and time-consuming to create aesthetically appealing designs, while plastic containers lack the durability and desirability of metal lids.
Innovation Solution
A container body made from molded plastic with a metal lid featuring a 'pop-top' easy-open mechanism, where the metal lid includes a weakened area for easy access, combining the design flexibility of plastic with the durability of metal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If metal containers are used with easy-open lids, then ease of operation is improved, but device complexity and manufacturing difficulty increase due to limitations in shaping metal
Solution Approach 1:
The container employs a composite structure combining a plastic container body with a metal lid. The plastic body can be easily molded into various shapes using standard molding techniques, while the metal lid provides the easy-open functionality. This composite approach allows each material to contribute its strengths without requiring the entire container to be made from a single difficult-to-form material.
2Shape
If metal containers are designed with new shapes, then aesthetic appeal may improve, but manufacturing time and cost increase significantly
Solution Approach 1:
The container is divided into two separate components: a plastic body and a metal lid. This segmentation allows the plastic body to be molded independently using efficient plastic molding processes that can quickly produce various shapes and designs, while the metal lid is manufactured separately and attached afterward. This eliminates the need to create entirely new metal molds for each design variation.
3Ease of manufacture
If plastic containers are used, then manufacturing flexibility and design variety improve, but durability and consumer desirability decrease compared to metal
Solution Approach 1:
The container uses a composite construction where the plastic body provides manufacturing flexibility and design variety, while the metal lid contributes durability and structural strength. The metal lid acts as a protective element that enhances the overall reliability of the container, particularly for the opening mechanism and sealing functions.

AI summary
A container for storing a liquid or a solid may include a container body having a container side wall and a container bottom and a container lid having a pop top arm to pivot and cooperate with a weakened area to provide access to the interior of the container body. The container body may be formed from plastic and the container lid is formed from metal, and the container body may include a vertical neck. The container body may include a lip, and the bottom wall may include a center protrusion. The bottom wall may include a depression, and the bottom wall may include a radial extending depression.
