Rigid Cigarette Package Collapsible Collar Interspace Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid cigarette packages with reduced dimensions face challenges in providing sufficient surface area for information and health warnings due to minimized external space, and they require excessive cardboard for the internal frame.
Innovation Solution
A rigid package design featuring an external container with a smaller internal wrapper and a collapsible collar made of cardboard or stiff paper, which creates an interspace between the internal and external containers to maintain the cigarettes' position while minimizing cardboard usage, allowing standard-sized packages to hold fewer cigarettes effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the package dimensions are reduced to hold fewer cigarettes, then the quantity of cigarettes is reduced, but the surface area for information and health warnings is insufficient
Solution Approach 1:
The package is divided into two distinct containers: an external container and an internal wrapper. The internal wrapper is made smaller to hold fewer cigarettes, while the external container maintains standard dimensions to provide sufficient surface area for information and health warnings. This segmentation allows the package to accommodate reduced cigarette quantity without compromising the required warning surface area.
2Quantity of substance
If an internal frame is used to house fewer cigarettes, then the quantity of cigarettes is reduced, but the amount of cardboard used increases considerably
Solution Approach 1:
The invention extracts the rigid structural function from a traditional internal frame and transfers it to the external container. The external container is sized to hold the smaller number of cigarettes, providing the necessary structural support and rigidity. This eliminates the need for a separate internal frame, thereby reducing cardboard usage while maintaining package integrity.
Solution Approach 2:
The internal wrapper is nested within the external container, with the internal wrapper being smaller in size. This nested configuration allows the external container to serve as both the outer housing and the primary structural element, eliminating the need for additional framing materials and reducing overall cardboard consumption.
3Volume of stationary object
If the internal wrapper is tightly enclosed by the external container, then the space utilization is optimized, but the surface area for information and warnings is reduced
Solution Approach 1:
The package structure is segmented into an external container and an internal wrapper with distinct dimensions. The external container maintains standard size to ensure sufficient surface area for information and warnings, while the internal wrapper is reduced in size to match the smaller quantity of cigarettes. This segmentation resolves the conflict between space utilization and surface area availability.

AI summary
A rigid package for smoking articles comprises a bundle (4) of articles enclosed by an internal wrapper (3) and a rigid external container (2) housing the internal wrapper (3) and having an open extremity (21). A rigid collar (5) placed between the wrapper (3) and the container (2) projects partially from the open extremity. An empty interspace (7) between the internal wrapper (3) and the external container (2) is provided by means of two tabs (55) of the collar (5), each tab (55) being positioned as a continuation of each of two lateral walls (52) and placed perpendicularly to a rear wall (54) of the collar (5). The tabs are in contact with an inner wall of the external container (2) and fix the internal wrapper (3) in an interspaced position with regard to the external container (2).
