Paperboard Container with Removable Cap and Dosing Indicia
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing paper-based containers for household products are inconvenient to open and secure to close, and they lack a mechanism for controlled dosing of contents.
Innovation Solution
A container design featuring a paperboard shell layer with a body portion, a removable portion, and a cap portion, along with a paperboard core layer and an overlapping longitudinal seam, which allows for easy opening, secure reclosing, and controlled dispensing of contents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If simple prism or right circular cylinder shaped containers with fold and close mechanisms are used, then the container structure is simple and easy to manufacture, but the closure mechanism lacks sufficient integrity to maintain contents when the container is tipped over or inverted
Solution Approach 1:
The container is divided into distinct functional segments: a body portion, a removable portion with tear-off characteristics, and a cap portion. This segmentation allows each component to perform its specific function - the body provides structural integrity, the removable portion enables controlled opening, and the cap provides secure closure that maintains integrity when tipped over.
Solution Approach 2:
The removable portion is designed with predetermined tear-off lines and is pre-configured to separate from the body portion at a controlled location. This preliminary design ensures that when the container is opened, the removable portion detaches cleanly, and when reclosed, the cap portion secures reliably to the body portion, solving the integrity problem before use begins.
2Reliability
If flaps are added to the open end of the container to improve closure integrity, then the container can be securely reclosed, but the flaps interfere with pouring and make it difficult for users to see and controllably pour contents
Solution Approach 1:
The removable portion is designed to be completely removed from the body portion upon opening, rather than leaving interfering flaps in place. This extraction of the problematic element allows the container to be securely reclosed with the cap portion while eliminating the interference with pouring and visibility issues that would result from leaving flaps attached.
Solution Approach 2:
Instead of adding flaps to the open end to improve closure, the design inverts the approach by removing a portion of the container wall to create an opening that can be sealed by the cap portion. This inversion resolves the contradiction by eliminating the interfering flaps while maintaining secure closure through the cap-body engagement mechanism.
3Ease of operation
If the container is designed for easy opening by removing a predetermined portion, then the container can be easily opened, but the closure mechanism may not be secure enough to prevent spills when tipped over
Solution Approach 1:
The container is segmented into a body portion and a removable portion that can be easily separated at a predetermined location. This segmentation enables easy opening while the cap portion, when reclosed, engages securely with the body portion to prevent spills, thus resolving the contradiction between ease of opening and closure security.
Solution Approach 2:
The removable portion is pre-designed with tear-off lines and detachment features that enable easy removal. The cap portion is pre-configured to engage securely with the body portion upon reclosure. These preliminary designs ensure that both easy opening and secure closure are achieved without compromise.
4Shape
If flaps are present at the open end of the container, then the container structure is complete, but the flaps interfere with pouring and make it difficult for users to precisely dispense the desired quantity of contents
Solution Approach 1:
The removable portion is extracted and removed from the container structure upon opening, eliminating the flaps that interfere with pouring and dispensing. This extraction maintains the completeness of the container structure during storage while enabling precise dispensing control during use.
Solution Approach 2:
Instead of completing the container structure with flaps that interfere with dispensing, the design inverts the approach by removing a portion to create an opening that can be sealed. This inversion resolves the contradiction by maintaining structural completeness during storage while enabling precise dispensing control through the cap portion.

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 shell layer has an interior facing surface oriented towards the longitudinal axis of the container. The interior facing surface above the lower line of limitation includes at least one dosing indicia.
