Sealing Stamp with Tear-Off Portion for Soft Cigarette Packages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing soft cigarette packages require inconvenient and often difficult tearing mechanisms for opening, either involving ripping the sealing stamp and inner wrapper simultaneously or relying on pre-weakened tear-open lines that are not entirely straightforward for immediate access.
Innovation Solution
A soft cigarette package design featuring a sealing stamp that completely overlaps the top wall of the inner wrapper, glued only to the inner wrapper, with a removable tear-off portion and a pre-weakened tear-open line facilitating easy tearing, allowing the smoker to grasp and pull the removable portion for immediate access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the sealing stamp is glued to the outer wrapper and arranged astride the top wall of the inner wrapper, then the sealing stamp provides structural support and retention, but the smoker must rip through multiple layers (outer wrapper and sealing stamp) making opening difficult and inconvenient
Solution Approach 1:
The sealing stamp is divided into two functional parts: a fixed portion glued to the outer wrapper that provides structural support, and a removable tear-off portion that facilitates easy opening. This segmentation allows the stamp to simultaneously provide reliable retention while enabling convenient access by the smoker.
Solution Approach 2:
The tear-off portion is extracted as a separate, removable element from the sealing stamp. This extracted portion can be easily removed by the smoker to access the cigarettes, while the remaining fixed portion continues to provide structural support and sealing function.
2Area of stationary object
If the sealing stamp exclusively overlaps the top part of the inner wrapper and is glued to it, then the sealing stamp provides complete coverage, but the smoker must rip both the sealing stamp and inner wrapper simultaneously which is not entirely convenient
Solution Approach 1:
The sealing stamp is segmented into a fixed portion that maintains complete coverage of the top wall for security and aesthetics, and a separate tear-off portion that provides an easy-grip opening mechanism. This allows full coverage to be maintained while simplifying the opening action.
Solution Approach 2:
The tear-off portion is pre-configured with a tear line or weakened structure that allows the smoker to easily initiate tearing. This preliminary preparation of the opening mechanism eliminates the need to rip through multiple bonded layers simultaneously.
3Ease of operation
If a pre-weakened tear-open line is provided in the sealing stamp, then the tearing process is simplified, but the tear-removable portion may not be easily graspable for immediate access
Solution Approach 1:
The sealing stamp is divided into a fixed portion and a tear-off portion connected by a pre-weakened tear line. The tear-off portion is designed with sufficient size and shape to be easily grasped by fingers, while the pre-weakened line ensures immediate tearing upon application of force, minimizing opening time.
Solution Approach 2:
The tear-off portion acts as an intermediary element between the user's hand and the sealed package contents. It provides a convenient gripping surface that transfers force efficiently to the pre-weakened tear line, enabling rapid opening without direct manipulation of the sealed edges.

AI summary
A soft cigarette package (1) having: a group (4) of cigarettes; an inner wrapper (3), which encloses the group (4) of cigarettes and has a top wall (5); an outer wrapper (2), which surrounds the inner wrapper (3) on five sides leaves the wall (5) of the inner wrapper (3) exposed; and a sealing stamp (19), which has a rectangular shape and at least partially overlaps the top wall (5) of the inner wrapper (3) and has a tear-removable portion (26), which is separated from the remaining part of the sealing stamp (19) by means of a pre-weakened tear-open line (27).
