Paperboard Household Container With Removable Cap for Spill Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper-based containers face challenges in controlled dispensing and secure reclosing, particularly due to flaps and slots that complicate pouring and lead to spills, especially when tipped over.
Innovation Solution
A container design featuring a paperboard shell with a removable portion and a core layer, including lobes for secure reclosure, allowing controlled dispensing and easy opening, with a cap portion that wedges onto the body portion for stable closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If flaps and slots are added to the container opening for closure functionality, then the container can be reclosed to protect contents, but the complexity of opening and dispensing operations increases
Solution Approach 1:
The container opening is segmented into a body portion and a removable cap portion. The cap portion can be completely removed from the body portion, providing simple access for dispensing operations while maintaining the ability to securely reclose by replacing the cap on the body portion's lobes.
2Ease of manufacture
If the container has a simple prism or cylinder shape, then manufacturing is simplified, but controlled pouring and dispensing becomes difficult
Solution Approach 1:
While maintaining an overall simple prism or cylinder shape for easy manufacturing, the container incorporates localized structural features including lobes protruding from the body portion and corresponding recesses in the cap portion. These localized features enable controlled pouring and secure reclosure without complicating the overall container geometry or manufacturing process.
3Reliability
If flaps are positioned at the open end for closure, then the container can be sealed, but the flaps interfere with pouring and visibility
Solution Approach 1:
The closure system is segmented into a removable cap portion that sits atop the body portion rather than flaps integrated at the opening edge. This separation allows the cap to be completely removed for unobstructed pouring and visibility, while still providing secure closure when placed back on the body portion's lobes.
4Ease of operation
If the container is designed for easy opening, then user convenience is improved, but controlled dosing of contents becomes difficult
Solution Approach 1:
The container is segmented into a body portion and a removable cap portion. The cap portion can be completely removed for convenient access, and when replaced for reclosure, it engages with lobes on the body portion to provide secure sealing. This segmentation enables both easy opening and controlled dosing operations.
Solution Approach 2:
The container incorporates localized features including lobes on the body portion and corresponding recesses in the cap portion. These features enable secure mechanical engagement for reliable reclosure while maintaining overall simplicity for easy manufacturing and operation.

AI summary
A container including a paperboard shell layer and a paperboard core layer. The container has a predetermined removable portion the provides for a separable cap portion. The body portion of the container extends from the shell bottom edge to a lower line of limitation. The core layer has a core rim located at a rim distance that is a function of position about the longitudinal axis of the container.
