Hinge-Lid Cigarette Pack Click Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing folding boxes for cigarettes lack a simple and cost-effective way to produce a clicking noise when the lid is opened, requiring additional parts or complex mechanisms.
Innovation Solution
The use of embossed projections on the packaging material, specifically thin cardboard, to create support elements that interact with a pivotable tab or click tongue, generating a clicking noise without additional components, and allowing for improved production integration with existing manufacturing processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional parts or complex mechanisms are used to produce clicking noise, then the clicking noise function is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The packaging material itself serves dual purposes: it provides structural support and generates the clicking noise through embossed projections. The embossed projections on the collar front wall automatically engage with the lid inner flap during opening, producing the desired clicking sound without requiring separate noise-generating components.
Solution Approach 2:
The support function and noise-generating function are merged into a single integrated structure. The embossed projections on the collar simultaneously provide mechanical support for the lid and create the clicking noise through their interaction with the lid inner flap, eliminating the need for separate functional components.
2Reliability
If additional parts or complex mechanisms are used to produce clicking noise, then the clicking noise function is improved, but the manufacturing process complexity increases
Solution Approach 1:
The embossed projections are pre-formed on the collar during the blank production stage using standard embossing tools. This preliminary action ensures that the noise-generating features are already in place before assembly, requiring no additional manufacturing steps or specialized equipment during the packaging process.
Solution Approach 2:
The existing embossing and punching tools used for producing the collar structure are also used to create the noise-generating embossed projections. This multi-functional use of standard manufacturing equipment maintains production efficiency while adding the clicking noise capability.
3Reliability
If embossed projections are made with sufficient depth to enter recesses, then the closing function is improved, but the projections may be deformed and effectiveness reduced
Solution Approach 1:
The depth and dimensions of the embossed projections are precisely controlled within specific ranges to optimize performance. The projections are designed with adequate depth to enter the recesses and provide reliable closing function, while maintaining sufficient structural integrity to avoid deformation during the closing operation.

AI summary
A cigarette pack embodied as a hinge-lid pack is provided with elements which produce a "click" sound when the lid (11) is opened. These elements are embossed protrusions (33), which are preferably applied to a collar front wall (29) by means of material deformation, and pivotable tab click-lugs (38) which are applied by means of a corresponding stamping method in the region of an inner-lid tab (20). Both interacting supporting elements form supporting edges (36) and counter-supporting edges (40).
