Pivoting Closure Tab for Tobacco Pack Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The mechanical application of sealing labels to inner packaging in cigarette packs is complex, cost-intensive, and prone to errors, particularly regarding precise positioning.
Innovation Solution
A pack design featuring a pivotally mounted closure tab made of dimensionally stable material, connected to the inner packaging and the outer pack's lid, which automatically transitions from a closed to an open position when the lid is opened, ensuring precise and error-free sealing of the removal opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multi-action film closure labels are used to close the removal opening, then the sealing function is achieved, but the mechanical application becomes complex and costly
Solution Approach 1:
The invention extracts the sealing function from the complex multi-action film closure label system and implements it through a simple adhesive tab made of the same material as the inner pack. The adhesive tab is directly formed from the inner pack material itself, eliminating the need for separate complex closure labels and their mechanical application systems.
Solution Approach 2:
The adhesive tab is made from the same dimensionally stable material as the inner pack, creating homogeneity in material properties. This eliminates the need for different materials and complex assembly processes, simplifying both manufacturing and application while maintaining reliable sealing.
2Reliability
If multi-action film closure labels are used, then sealing is achieved, but precise positioning becomes error-prone
Solution Approach 1:
The adhesive tab is merged with the inner pack as a single integrated component made from the same material blank. This integration eliminates positioning errors that occur when separate closure labels are mechanically applied, as the tab is inherently positioned correctly through the folding and sealing process.
Solution Approach 2:
The adhesive tab is pre-positioned and pre-formed during the manufacturing of the inner pack itself, before the pack is assembled. The tab is created as an integral part of the inner pack structure, ensuring precise positioning is built-in rather than added later through complex mechanical application processes.
3Ease of manufacture
If a pivotally mounted closure tab made of dimensionally stable material is used, then the sealing process is simplified, but the structural complexity of the closure mechanism increases
Solution Approach 1:
The adhesive tab is designed to be self-activating through the natural opening motion of the inner pack. When the user opens the pack, the fold line automatically causes the tab to pivot and apply the adhesive seal without requiring any additional mechanical components, buttons, or complex actuation mechanisms.
Solution Approach 2:
The closure tab utilizes dynamic motion through a fold line that allows it to pivot from a retracted position during opening to an extended position during closing. This dynamic behavior enables the simple adhesive tab to achieve reliable sealing through natural pack manipulation without adding mechanical complexity.

AI summary
The invention relates to a pack for products of the tobacco industry, comprising an outer pack (10) which is designed particularly as a flip pack having a pack part (11) and a cover (12) and which is manufactured from a blank made of dimensionally stable material, as well as comprising at least one inner pack (13), in particular a box-shaped inner pack, which is arranged in the outer pack (10), is also manufactured from a blank made of dimensionally stable material, and encloses the products on all sides, wherein the inner pack (13) has a closure means (34) which, prior to the inner pack (13) being used for the first time, closes a removal opening (32) which extends at least in an end region of the inner pack (13), preferably additionally in a front region of the inner pack (13), and is intended for removing individual products, and which closure means can be transferred from the state in which it closes the removal opening (32) to a state in which it exposes the removal opening (32). According to the invention, the closure means consists of dimensionally stable material, in particular of preferably coated cardboard.
