Rigid Hinged-Lid Package With Folded Information Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Rigid hinged-lid cigarette packets face challenges in providing sufficient space for information, are costly to produce, and the separate coupon is awkward to use and reuse.
Innovation Solution
A rigid hinged-lid package design with an additional panel hinged to the container, which can be folded and refolded easily, allowing information to be printed on it, eliminating the need for a separate coupon and simplifying production.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a separate coupon is provided inside or outside the packet, then information can be supplied to customers, but production costs increase and the coupon becomes awkward to use and discard
Solution Approach 1:
The patent integrates the information leaflet directly into the packet structure by printing it on the inner surface of the lid, merging the information delivery function with the packaging structure. This eliminates the need for separate coupon materials and reduces production complexity while ensuring information is always present with the packet.
Solution Approach 2:
The lid serves multiple functions: it provides mechanical protection, enables packet opening/closing, and simultaneously displays information on its inner surface. This multi-functionality eliminates the need for separate information carriers and reduces overall device complexity.
2Loss of information
If a folding leaflet is glued to the packet wall, then information can be provided, but the leaflet is difficult to fix back onto the packet after unfolding
Solution Approach 1:
Instead of attaching the information carrier to the packet body and having it fold outward, the patent inverts the approach by printing information on the inner surface of the lid itself. The lid naturally folds closed over the information, keeping it secure and easily visible without requiring additional attachment mechanisms.
Solution Approach 2:
The lid's natural closing action automatically secures the information in place without requiring user intervention to re-attach it. The structure itself provides the securing function through its inherent closing mechanism, making the system self-servicing.
3Loss of information
If the outer surface of the packet is used for printing, then brand and health warnings can be displayed, but there is insufficient space for additional information
Solution Approach 1:
The patent utilizes the inner surface of the lid as an additional printable dimension that is not visible when the packet is closed but becomes accessible when opened. This adds information capacity without compromising the external appearance or occupying additional external space.
Solution Approach 2:
The information is nested within the packet structure on the inner lid surface, allowing it to be contained within the existing packet boundaries. This nesting approach maximizes information capacity while maintaining the compact external dimensions of the packet.

AI summary
A rigid package for tobacco articles has a cup-shaped container, which is substantially parallelepiped-shaped and has two major lateral walls, two minor lateral walls, a bottom wall, and an open top end; a cup-shaped lid hinged along a first hinge to rotate between an open position and a closed position respectively opening and closing the open end; and an additional panel hinged to the container along a second hinge to rotate, with respect to the container, between an unfolded position, in which the additional panel is detached from the container, and a folded position, in which the additional panel rests on a major lateral wall of the container and is maintained contacting the major lateral wall of the container by the lid in the closed position.
