Packaged Oral Care Implement with Pre-Weakened Shear Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current oral care implement packaging struggles to balance tampering prevention, visibility, structural stability, and ease of opening, often competing with each other.
Innovation Solution
A packaged oral care implement design featuring a first panel with pre-weakened lines of differing shear strengths, where a tab protrudes into a tear-away portion, allowing easy opening while maintaining structural integrity and preventing undetectable tampering, with the oral care implement acting as a foundation to assist in shearing the panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealed package is used to prevent tampering and maintain structural stability, then tampering prevention and structural stability are improved, but ease of opening deteriorates
Solution Approach 1:
The package incorporates pre-weakened lines formed during the molding process, creating predetermined fracture paths that guide the opening action. This preliminary preparation allows the package to be securely sealed during transport while enabling easy opening by the consumer through simple tearing or breaking along the pre-formed lines.
Solution Approach 2:
The package structure is divided into segments connected by pre-weakened lines, allowing the package to be separated into distinct portions during opening. The tab and panel are segmented such that the pre-weakened line creates a controlled separation path, making opening easier while maintaining package integrity when sealed.
2Stability of the object's composition
If a sealed package is used to maintain structural stability, then structural stability is improved, but ease of opening deteriorates
Solution Approach 1:
The pre-weakened lines are formed during the molding process, creating predetermined fracture paths that guide the opening action. This preliminary preparation allows the package to be securely sealed during transport while enabling easy opening by the consumer through simple tearing or breaking along the pre-formed lines.
Solution Approach 2:
The package structure has different properties in different locations: the majority of the package maintains full structural strength for stability during transport, while the pre-weakened lines have reduced strength specifically at the opening location. This local variation in quality allows the package to be both structurally stable and easy to open.
3Ease of operation
If a tab is added to assist opening, then ease of opening is improved, but device complexity deteriorates
Solution Approach 1:
The tab is integrated into the existing package structure as a single molded component rather than being a separate part. The pre-weakened line is formed as part of the molding process, creating a unified structure that combines the tab, panel, and opening mechanism into one piece, thereby improving ease of opening without significantly increasing device complexity.
Solution Approach 2:
The package structure itself provides the opening mechanism through the pre-weakened line and tab configuration. The oral care implement positioned in the cavity acts as a foundation that assists in shearing the first panel when force is applied to the tab, allowing the product to help open its own package without requiring additional complex mechanisms.
4Ease of operation
If pre-weakened lines of differing shear strengths are used to provide targeted easy open location, then ease of opening is improved, but manufacturing precision deteriorates
Solution Approach 1:
The pre-weakened lines with differing shear strengths are formed during the molding process, creating predetermined fracture paths with controlled strength variations. This preliminary preparation allows the package to be securely sealed during transport while enabling easy opening by the consumer through simple tearing or breaking along the pre-formed lines.

AI summary
A packaged oral care implement (1000) and method of opening the same. In one embodiment, the package (2000) includes a tab (106) on a first panel (100) of the package that is strategically located so that the oral care implement itself (1000) acts as a foundation or barrier adjacent to the tab that assists with shearing the first panel to release the tab.
