Cigarette Pack Inner Structure with Integrated Actuation Tab
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cigarette packaging designs are material-intensive and complex, making them costly and difficult to produce using efficient packaging machines, while also failing to maintain aroma and moisture sealing effectively.
Innovation Solution
The design features a separate actuation tab attached directly to the inner pack, with a closure tab and adhesive covering the removal opening, and the inner pack consists of two thin cardboard blanks that can be produced using standard folding box processes, allowing for efficient production and maintaining aroma and moisture tightness without additional inner wrapping.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a multi-part pack with separate inner wrapping and film sealing is used, then aroma and moisture sealing is improved, but material cost and structural complexity increase
Solution Approach 1:
The patent combines the inner packaging and sealing functions into a single integrated cartón structure. The cartón includes integrated closure tabs (first and second closure tabs) that are part of the same blank, eliminating the need for separate inner wrapping and film sealing components. This merging maintains sealing reliability while reducing structural complexity and material usage.
Solution Approach 2:
The cartón serves multiple functions simultaneously: it provides structural containment, aroma and moisture sealing, and includes integrated closure mechanisms. The single blank design performs both packaging and sealing functions that previously required separate components, reducing overall pack complexity while maintaining reliability.
2Reliability
If a multi-part pack with separate inner wrapping and film sealing is used, then aroma and moisture sealing is improved, but production efficiency decreases
Solution Approach 1:
The integrated cartón design allows the entire packaging structure to be formed from a single blank, enabling production on standard folding box machines rather than requiring complex multi-component assembly equipment. This merging of functions into one component significantly improves production efficiency while maintaining sealing reliability.
3Reliability
If additional inner wrapping and film sealing are used, then aroma and moisture sealing is improved, but material cost increases
Solution Approach 1:
The patent eliminates redundant materials by integrating sealing functions into the cartón structure itself. The first and second closure tabs, along with the removal opening design, provide aroma and moisture sealing without requiring additional inner wrapping or film layers, thus reducing total material usage while maintaining sealing reliability.

AI summary
An aroma-tight and moisture-tight pack for cigarettes (10) comprises an inner pack (12) made from cardboard, which is dense as a result of appropriate treatment, or a comparable packaging material and an outer pack (13) in the form of a hinge-lid box, but without a collar. A cigarette group (11) is positioned directly, i.e. without an inner envelope, in the inner pack (12). An upper region of the inner pack, specifically in the region of a lid (15) of the outer pack (13), is provided with a special opening aid. The whole surface area of a closure tab (39) of the inner pack (12) is covered by an actuating tab (42) which is in the form of tape and is made from a separate blank.
