Tamper Evident Tape Segmentation for Tobacco Containers
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tamper evident labels on tobacco containers are either fully removable or require a wider, more expensive longitudinally separable design to provide sufficient tamper evidence, which is not cost-effective.
Innovation Solution
A tamper evident tape with a line of separation allowing the first portion to be easily removable and the second portion to remain adhered, using a combination of non-permanent and permanent adhesives, and optionally featuring perforations, notches, and pull-tabs, to indicate tampering without the need for excess material.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional fully removable label is used, then the label can be completely removed to access the tobacco product, but no tamper evidence remains on the container
Solution Approach 1:
The label is divided into two distinct portions: a first portion that is fully removable to allow product access, and a second portion that remains adhered to the container as tamper evidence. This segmentation resolves the contradiction by enabling both complete removal for access and retention of evidence through separate functional segments of the same label structure.
2Reliability
If a longitudinally separable label is used to provide tamper evidence, then the label can be separated to allow access while retaining evidence, but the label must be wider and is more expensive
Solution Approach 1:
Different adhesive properties are applied to different portions of the label: the first portion uses a removable adhesive allowing complete removal, while the second portion uses a permanent adhesive to retain tamper evidence. This local differentiation of adhesive quality enables the label to provide both access and evidence functions without requiring excessive width or material quantity.
3Reliability
If a wider longitudinally separable label is used, then sufficient width is provided for both removable section and tamper evident section, but the material cost increases
Solution Approach 1:
The label is segmented into two portions with different adhesive characteristics, allowing the first portion to be completely removed and the second portion to remain as compact tamper evidence. This segmentation eliminates the need for excessive label width that would be required if a single uniform adhesive type were used, thereby reducing material consumption and manufacturing cost while maintaining reliable tamper evidence functionality.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides effective tamper evidence without the material costs associated with wider labels, allowing the container to be opened while maintaining tamper evidence integrity, even with repeated use.
Implementation Method 1
The tape may comprise a layer of non-permanent adhesive between a rear surface of the first portion of the tape and a surface of the container, and a layer of permanent adhesive between a rear surface of the second portion of the tape and a surface of the container

AI summary
A tape (200) for adhering to a container (100) and a container comprising the tape, the tape (200) comprising first and second longitudinal edges (211,212) defining a boundary of the tape (200) and a line of separation (300) extending between said edges to divide the tape into first (400) and second (500) portions, the first portion (400)being severable from the second portion (500) along the line of separation (300) such that the first portion (400) can be removed from the container (100) and the second portion (500) can remain adhered to the container (100) as tamper evidence.
