Seamless Stackable Container Rim Structure for Airtight Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing stackable containers with seams and folds are prone to leaks, require separate lids, and generate excess waste, making them inefficient for packaging liquid products and increasing material consumption.
Innovation Solution
A seamless container design with a protruding rim structure featuring grooves and protrusions that align and interlock with similar containers, forming an airtight and watertight closed volume without separate lids, using materials like fibrous materials or thermoplastics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate lids are used to close containers, then containers can be closed and stored separately, but material consumption increases and storage space increases
Solution Approach 1:
The invention merges the container body and lid into a single integrated structure where the rim of the container body forms interlocking features (protrusions and grooves) that directly engage with the flange of the lid, eliminating the need for separate closure components and reducing material consumption
2Reliability
If separate lids are used to close containers, then containers can be closed and stored separately, but storage space increases
Solution Approach 1:
The integrated design allows the lid and container body to be stored together in a nested configuration, reducing the total storage volume compared to storing separate lids and containers in different stacks
3Ease of manufacture
If containers are made with folds and seams, then containers can be manufactured from cardboard or paper, but leaks occur and airtight sealing is impossible
Solution Approach 1:
The invention uses a seamless, molded thin-walled structure made from thermoplastic or thermosetting plastic material that forms continuous surfaces without folds or seams, enabling airtight and watertight sealing while maintaining ease of manufacture through injection molding or similar processes
Solution Approach 2:
The container structure combines thermoplastic or thermosetting plastic material to create a seamless body that integrates the rim and wall structure, eliminating the need for folds and seams while achieving reliable sealing performance
4Ease of manufacture
If containers have folds and seams, then containers can be manufactured from cardboard or paper, but hard-to-reach areas increase food waste
Solution Approach 1:
The seamless molded structure creates smooth, continuous surfaces without folds or seams, eliminating hard-to-reach areas where food would be trapped and wasted, while maintaining ease of manufacture through modern plastic forming processes
5Ease of manufacture
If containers have overlapping areas from folding, then containers can be manufactured from cardboard or paper, but material consumption increases
Solution Approach 1:
The seamless molded thin-walled structure eliminates the need for overlapping areas required by folded construction, reducing material consumption while maintaining ease of manufacture through injection molding or similar processes
Solution Approach 2:
The use of thermoplastic or thermosetting plastic material allows for seamless molded construction that eliminates overlapping areas and reduces overall material consumption compared to folded cardboard or paper containers
