Hinged Lid Glued to Container Base for Rigid Tobacco Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid, hinged-lid cigarette packets tend to deform and fail to adequately protect cigarettes under stress, often leading to accidental opening and contents loss, while existing solutions are expensive to produce.
Innovation Solution
A rigid package design featuring a parallelepiped-shaped container with a cup-shaped lid formed by folding two independent blanks, where the lid is glued to the container's bottom end wall, incorporating a hinge and stop members to prevent accidental opening, and allowing for easy production on standard packing machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the lid is glued to the container bottom end wall, then the package strength and stability are improved, but the manufacturing complexity increases
Solution Approach 1:
The package is divided into two separate components: the container and the lid, each formed from independent blanks. The lid is then attached to the container bottom end wall, allowing each component to be manufactured separately and assembled together, which simplifies the overall manufacturing process while maintaining structural strength
Solution Approach 2:
The lid is glued to the container bottom end wall, merging two separate components into a unified structure. This combination provides the necessary strength and stability to the package while allowing each component to be manufactured independently using standard packing machine processes
2Ease of operation
If the lid is made cup-shaped and hinged, then the ease of operation is improved, but the reliability of preventing accidental opening deteriorates
Solution Approach 1:
The lid is designed with a hinge connection, making it dynamically movable between closed and open positions. This dynamic design allows easy opening when needed while the closed position provides reliable protection against accidental opening due to the stable hinged connection and proper sealing
Solution Approach 2:
The hinge acts as an intermediary mechanism between the lid and container, providing controlled movement. It allows the lid to open easily when intended while preventing accidental opening through its mechanical design, which requires deliberate action to disengage
3Manufacturing precision
If the container is made parallelepiped-shaped, then the manufacturing precision and standardization are improved, but the protection against stress deformation deteriorates
Solution Approach 1:
The container is segmented into multiple panels formed from a single blank, with fold lines creating the parallelepiped shape. This segmentation allows precise manufacturing of each panel while the folded structure provides inherent flexibility to absorb stress and prevent deformation
Solution Approach 2:
Different portions of the container blank are assigned different functions: the parallelepiped shape provides structural integrity and manufacturing precision, while the cup-shaped lid provides stress absorption and protection. Each component is optimized for its specific function to achieve both precision and deformation resistance
