Rigid Cigarette Packet Collar with Partition Wall
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rigid packets of cigarettes with hinged lids for reduced-size cigarettes face manufacturing complexities and increased material usage, leading to higher production and disposal costs due to the need for filler elements that occupy significant space and material.
Innovation Solution
A rigid packet design with a hinged lid that incorporates a collar with an intermediate partition wall, dividing the inner volume into two chambers, allowing for reduced material usage and simpler manufacturing processes, where the secondary chamber can house additional items like a lighter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a filler element is inserted inside the packet to occupy the inner volume left free by reduced-size cigarettes, then the stability of cigarettes during handling is improved, but the device complexity and material consumption increase
Solution Approach 1:
The collar is segmented into multiple functional parts: front wall, rear wall, lateral walls, and an intermediate partition wall that extends into the inner volume. This segmentation allows the collar itself to create compartments without requiring separate filler elements, thereby maintaining cigarette stability while simplifying the overall structure and manufacturing process
Solution Approach 2:
The collar serves multiple functions: it structurally supports the packet, divides the inner volume into compartments, and eliminates the need for separate filler elements. The intermediate partition wall specifically addresses the stability requirement while the collar integrates this function into its own structure rather than requiring an additional component
2Stability of the object's composition
If a filler element is inserted inside the packet to occupy the inner volume left free by reduced-size cigarettes, then the stability of cigarettes during handling is improved, but the material consumption and production costs increase
Solution Approach 1:
The function of occupying and stabilizing the inner volume is merged into the collar structure itself through the intermediate partition wall. This eliminates the need for separate filler elements made of corrugated cardboard, thereby reducing material consumption and production costs while maintaining the stability of reduced-size cigarettes during handling
Solution Approach 2:
The collar serves multiple functions including structural support, volume occupation, and cigarette stabilization. By making the collar multi-functional, the design eliminates the need for additional filler materials, thereby reducing material consumption and production costs
3Loss of substance
If the inner volume is divided into multiple chambers using partition walls, then the material consumption is reduced, but the manufacturing precision requirements increase
Solution Approach 1:
The intermediate partition wall is pre-formed as an integral part of the collar during the collar manufacturing process. This preliminary action ensures precise positioning and alignment of the partition wall relative to the collar structure, eliminating the need for complex post-assembly adjustments and reducing manufacturing precision requirements during final packet assembly

AI summary
A rigid packet (1) of smoking articles having: a parallelepiped-shaped container (2); at least one inner package (3), which encloses a group of smoking articles, is housed inside the container (2), and has a smaller cross dimension with respect to the cross dimension of the container (2); a lid (5) which is hinged to the container (2) to close an open top end (4) of the container (2) itself; and a collar (12), which is arranged inside the container (2) so as to project partly outwards of the open top end (4) and has at least one wall (17), centrally arranged, which divides the inner volume of the container (2) itself into an open-topped main chamber (18) housing the inner package (3) and in a secondary chamber (19) arranged side by side to the main chamber (18); the intermediate partition wall (17) initially forms part of a front wall (37) of the collar (12) and possibly of a lateral wall (13, 16) of the collar (12), is separated from the front wall (37) of the collar (12) by means of at least one incision (38; 40), and is folded 90° with respect to the front wall (37) of the collar (12) itself.
