Cigarette Pack Sleeve Intermediate Surface Design
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cigarette packs are easily copied and lack design features that attract consumer attention, making them unremarkable and vulnerable to duplication.
Innovation Solution
The introduction of an intermediate surface on the sleeve, which interrupts the fold line between adjacent side walls and has a different plane course, increases manufacturing complexity and allows for unique optical effects, making the pack more difficult to duplicate and visually appealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If an intermediate surface is introduced on the sleeve to interrupt the fold line, then the pack becomes more difficult to copy and visually appealing, but the manufacturing complexity increases
Solution Approach 1:
The intermediate surface is formed with a curved or non-linear contour that interrupts the fold line between adjacent side walls. This curvature creates unique optical effects and tactile features while maintaining manufacturability through standard forming processes, resolving the contradiction between visual appeal and manufacturing complexity.
Solution Approach 2:
The intermediate surface creates an asymmetric configuration on the otherwise symmetric pack structure. By positioning and shaping the intermediate surface to interrupt fold lines in a non-uniform manner, the pack achieves unique visual characteristics that prevent copying while using standard manufacturing techniques.
2Ease of operation
If the intermediate surface is arranged to provide tactile cues for opening, then ease of operation improves, but manufacturing precision requirements increase
Solution Approach 1:
The intermediate surface is positioned at specific locations on the pack where tactile feedback is most useful for opening operations. By concentrating the functional feature at key locations rather than distributing it uniformly, the design achieves ease of operation while maintaining reasonable manufacturing precision requirements.
3Strength
If the sleeve is made to surround the slide with intermediate surfaces, then pack integrity is maintained, but friction increases making slide actuation harder
Solution Approach 1:
The intermediate surface is designed as a segmented feature that interrupts the fold line but maintains structural continuity. The surface is divided into zones that provide structural support in some areas while creating clearance or reduced friction zones in others, allowing the slide to move easily while maintaining pack integrity.

AI summary
The invention relates to a package for cigarettes, having a slider (12) for receiving a package contents, in particular a group of cigarettes (15), and a sleeve (11) at least partially enclosing the slider (12) and open at both ends. According to the invention, an intermediate surface is formed on two adjacent side walls (27, 30; 28, 29) of the sleeve (11) and extends contiguously over parts of both adjacent side walls (27, 30; 28, 29) and interrupts a crease (33) between the two adjacent side walls (27, 30; 28, 29), wherein the adjacent side walls (27, 30; 28, 29) comprise a course in the area of the intermediate surface (32) deviating from the plane of the side walls outside of the intermediate surface (32).
