Tamper-Evident Closure Pendant for Package Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers lack effective anti-counterfeit measures to detect if they have been opened or tampered with, making it difficult to distinguish between original and counterfeit products.
Innovation Solution
A closure system with a pendant that is releasably coupled to the container and automatically drops into the container when the closure is removed, providing visible evidence of opening and tampering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a closure system is added to indicate package opening, then the ability to detect tampering is improved, but the device complexity increases
Solution Approach 1:
The closure system is divided into separate functional components: a closure body for sealing the container opening and a pendant indicator for displaying opening status. This segmentation allows each component to be optimized independently while working together to provide tamper evidence without excessive complexity
Solution Approach 2:
The pendant acts as an intermediary element that translates the closure's sealing function into a visible indicator state. It mediates between the closure mechanism and the user, providing clear visual feedback about package integrity without requiring complex electronic or mechanical systems
2Difficulty of detecting and measuring
If a pendant indicator is added to show package opening, then the detection of tampering is improved, but the manufacturing complexity increases
Solution Approach 1:
The pendant indicator is merged with the closure assembly, allowing both components to be manufactured and assembled as a single unit. This integration simplifies the manufacturing process by reducing the number of separate parts that need to be handled and assembled, while still providing effective tamper detection functionality
3Ease of operation
If the closure is made removably securable to indicate opening, then the ease of operation is improved, but the reliability of sealing decreases
Solution Approach 1:
The closure transitions from a static sealed state to a dynamic removable state when tampering is detected. The releasable coupling mechanism allows the closure to be easily removed to indicate opening, while the pendant remains as permanent evidence of the opening event, maintaining sealing integrity information
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 effectively indicates if a container has been opened from its original factory sealed condition, providing a clear indication of potential tampering and helping to prevent the repackaging of counterfeit products.
Implementation Method 1
the pendant is releasably coupled to the radially inner portion of the closure, and is releasable from the closure into the container upon removal of the closure from the container

AI summary
A product includes a closure having a radially inner portion, and being removably securable to a container, and a pendant releasably coupled to the radially inner portion of the closure, and being releasable from the closure into the container upon removal of the closure from the container. A package may include the product and a container, wherein the closure is removably secured to a neck of the container to removably close the container, and the pendant is suspended from the closure in an interior of the container neck, such that when the closure is removed from the container, the pendant releases from the closure and drops into the container and is non-removably carried therein to provide an indication that the package has been opened from its original factory sealed condition.
