Sliding Consumer-Good Packaging With Integrated Tamper Evidence
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packaging for consumer goods often lacks a clear indication of whether it has been opened, requiring additional layers like transparent plastic films, and may not adequately secure the contents.
Innovation Solution
Packaging with a first and second portion held together by a removable portion, allowing transformation from a closed to an open configuration through sliding, with tamper-evident features like a tear strip, ensuring the contents remain secure until use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Difficulty of detecting and measuring
If an outer transparent plastic film layer is added to indicate packaging opening status, then the ability to detect opening attempts is improved, but the device complexity increases
Solution Approach 1:
The packaging is divided into multiple functional portions: a first portion forming the receptacle, a second portion forming a closure, and a removable portion integrated with the closure. This segmentation allows the tamper-evident function to be built into the structural relationships between parts rather than requiring an additional outer film layer.
Solution Approach 2:
The tamper-evident indication function is merged with the closure mechanism itself. The removable portion is attached to both the first and second portions, and its detachment state directly indicates whether the packaging has been opened, eliminating the need for a separate indication layer.
2Device complexity
If a removable portion is integrated into the packaging structure to provide tamper evidence, then the device complexity is reduced, but the ease of operation deteriorates
Solution Approach 1:
The packaging transitions from a static sealed structure to a dynamic system with defined movement sequences. The first portion and second portion are configured to slide relative to each other, creating a progressive opening mechanism that guides the user through clear operational stages while maintaining security.
Solution Approach 2:
The closure mechanism is segmented into a removable portion and a remaining portion. The removable portion can be detached to provide tamper evidence, while the remaining portion maintains the structural integrity of the receptacle. This segmentation allows the opening operation to be simple (detaching one component) while still providing security functionality.
3Ease of operation
If the first and second portions are configured to slide relative to each other for opening, then the ease of operation is improved, but the reliability of product security deteriorates
Solution Approach 1:
The removable portion is pre-attached to both the first and second portions in the closed state, creating a preliminary security barrier. This preliminary attachment must be deliberately broken to access the contents, providing reliable tamper evidence before the sliding opening action occurs.
Solution Approach 2:
The packaging employs a dynamic sequence where the removable portion detachment (providing security evidence) and the sliding motion (providing access) are coupled but distinct actions. The relative sliding configuration ensures that even after the removable portion is detached, the first and second portions maintain a controlled relationship that preserves structural integrity and provides clear visual indication of the opening state.

AI summary
Packaging (10) for receiving a consumer good (100). The packaging comprises a first portion, a second portion, and a removable portion. The packaging (10) is moveable from a first configuration (C1), in which the first portion (12) and the second portion (14) are retained together by the removable portion (16) such that the first portion (12) and the second portion (14) of the packaging (10) define a closed receptacle (R) for receiving the consumer good (100). The packaging can then be moved from this first configuration (C1) to a second configuration (C2), in which the removable portion (16) is detached from at least one of the first portion and the second portion. From there, the first portion and the second portion can slide relative to each other, to a third configuration (C3), in which the first portion (12) is separated from the second portion (14) such that the receptacle (R) is exposed, such that the consumer good (100) can then be removed from the receptacle (R).
