Rigid Package With Hinged Lid And Collapsible Collar
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid cigarette packages of reduced dimensions face challenges in maintaining firm containment of cigarettes while optimizing space, often compromising on the available surface area for information and potentially failing to meet legal health warning requirements.
Innovation Solution
A rigid package design featuring an external container with a hinged lid and a collapsible collar that creates a cavity between the internal wrapper and the external container, allowing for firm containment of a smaller cigarette bundle within a standard-sized container, while maintaining package rigidity and allowing for additional information display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of stationary object
If the external container is made completely occupied by the bundle of cigarettes (tightly enclosed), then the space utilization is optimized, but the available surface area for information display is reduced
Solution Approach 1:
The package is divided into two functional zones: an internal wrapper that tightly encloses the cigarette bundle for space optimization, and an external container with free space for information display. This segmentation allows both requirements to be satisfied simultaneously.
Solution Approach 2:
The internal wrapper is nested within the external container, with the internal wrapper occupying the space needed for cigarettes while the external container provides additional surface area for health warnings and information without requiring increased overall package dimensions.
2Volume of stationary object
If the package dimensions are reduced to match smaller cigarette bundles, then the space utilization is improved, but the surface area for health warnings and information is insufficient
Solution Approach 1:
Instead of reducing package dimensions in all directions, the solution maintains standard external container dimensions to preserve surface area for regulatory information, while reducing only the internal wrapper volume to match the smaller cigarette bundle, effectively solving the problem in a different dimensional approach.
3Area of stationary object
If a standard-sized container is used for smaller cigarette bundles, then the surface area for information is maintained, but the containment firmness is compromised
Solution Approach 1:
The internal wrapper is designed with specific structural features including flaps and sealing mechanisms that provide localized reinforcement at critical points, ensuring firm containment of the cigarette bundle while allowing the overall package to maintain standard dimensions for information display.
Solution Approach 2:
The internal wrapper is pre-formed and inserted into the external container in a way that automatically positions and secures the cigarette bundle, ensuring firm containment is established before the package is sealed, preventing movement and deterioration during transport.

AI summary
The present invention refers to a rigid package for smoking articles comprising: a bundle (4) of articles; an internal wrapper (3) that encloses the bundle (4) of articles; a rigid external container (2) that houses the internal wrapper (3) and that has an open extremity (21); and a rigid collar (5) that partially projects from the open extremity (21) of the external container (2), said collar (5) being placed between the internal wrapper (3) and the external container (2); in which between the internal wrapper (3) and the external container (2) an empty cavity (7) is present and in which the collar (5) comprises at least one tab (55) placed facing the cavity (7) with one of its edges in contact with the external container (2) in order to distance and block the internal wrapper (3) in the external container (2), in order to keep the cavity (7) fixed, and in which the rear wall of the collar is formed by two tabs that join to form a fin (56) that is in contact with the rear wall of the external container.
