Hinge-Lid Cigarette Package with Breaking Separating Line
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing hinge-lid type packages for rod-like smoking articles require excessive wrapper resources and involve complex wrapping steps, leading to issues with tampering prevention and vending machine dispensing due to the use of film wrappers with tear tapes, which are prone to curling and getting caught.
Innovation Solution
A hinge-lid type package design that eliminates the need for film wrappers by incorporating a separating line that breaks to create a rotatable lid and inner frame, providing tampering prevention through visible breaking traces, thus reducing wrapper usage and avoiding issues with vending machine dispensing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a film wrapper with tear tape is used to prevent tampering, then tampering prevention is improved, but the pull end of the tear tape curls up and gets caught on dispensing guides in vending machines
Solution Approach 1:
The patent removes the film wrapper and tear tape from the package structure entirely. Instead, it uses a cardboard outer body with a hinge-lid mechanism and an inner frame with a separating line that breaks upon opening to provide tampering evidence. This extraction of the problematic film wrapper element resolves the dispensing issue while maintaining security through the breaking separating line.
2Reliability
If a transparent film wrapper is used to secure the inner pack, then tampering prevention is improved, but the package requires additional wrapping steps and consumes more wrapper resources
Solution Approach 1:
The patent eliminates the transparent film wrapper entirely from the packaging structure. The outer body and inner frame serve as the primary protective and security elements, with the separating line providing tampering detection without requiring any film wrapping steps.
Solution Approach 2:
The patent combines the protective and security functions into the rigid cardboard structure itself. The outer body provides physical protection, the inner frame provides structural support and guidance, and the separating line integrated into the inner frame provides tampering detection - all without requiring separate film wrapping layers.
3Ease of operation
If the inner frame has a U-shaped cross section to guide the lid, then lid guidance is improved, but the structure complexity increases
Solution Approach 1:
The patent applies the U-shaped cross section feature only to the specific portion of the inner frame that needs to guide the lid (the upper end portion), while other portions of the frame can have simpler structures. This localized application of complexity provides the necessary guidance function without unnecessarily complicating the entire frame structure.

AI summary
A hinge-lid type package for filter cigarettes is formed as a rectangular parallelepiped and includes an inner pack 36 of a cigarette bundle and a casing formed from a blank 50 as one sheet and accommodates the inner pack 36. The casing can be divided into an outer body 10 and a lid 12 by means of a separating line 14. When detached from the outer body 10 along the separating line 14, the lid 12 is rotated around a self hinge 16 to open or close.
