Tamper-Evident Child-Proof Package With Nested Securing Means
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current child-proof packaging solutions are complex and difficult to produce on conventional packaging machines, making them costly and inefficient for mass production, particularly for sectors like tobacco and cannabis products that require secure, tamper-evident packaging to prevent access by children.
Innovation Solution
A tamper-evident package design featuring an outer and inner package with securing means that prevent the inner package from being displaced or opened without deliberate action, utilizing latching mechanisms and a security card with tabs that engage with clearances in the outer package, requiring two hands or dexterity to open, and can be produced using conventional packaging machines.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex securing mechanisms are used to prevent child access, then safety is improved, but manufacturing complexity increases and production becomes difficult on conventional machines
Solution Approach 1:
The packaging system is divided into distinct functional components: an inner package containing the product, an outer package providing structural support, and separate securing means (latching mechanisms and security card) that can be independently manufactured and assembled. This segmentation allows each component to be produced using conventional packaging machinery while maintaining the overall child-proof functionality.
Solution Approach 2:
The inner package is nested within the outer package, with the securing means positioned to engage between these two nested packages. The latching mechanisms are disposed on the inner package and engage with corresponding features on the outer package, creating a compact integrated structure that maintains safety without requiring complex external mechanisms.
2Reliability
If complex securing mechanisms are used to prevent child access, then safety is improved, but production cost increases
Solution Approach 1:
The securing means are designed to be self-contained and self-activating. The latching mechanisms automatically engage when the inner package is inserted into the outer package, and the security card with tabs provides inherent tamper-evident functionality without requiring additional actuators or complex control systems. This self-service design eliminates the need for expensive specialized manufacturing equipment.
Solution Approach 2:
The security card is designed as a disposable component that provides tamper-evident functionality through simple tab engagement. Once the package is opened, the security card's tabs are displaced or broken, providing irreversible evidence of opening. This disposable approach to security features is far more cost-effective than reusable complex locking mechanisms.
3Reliability
If multiple securing means are used to impede package opening, then child-proof effectiveness is improved, but the package requires more components and assembly steps
Solution Approach 1:
Multiple securing functions are merged into a single integrated security card component. The card incorporates multiple tabs that can engage with corresponding features on both the inner and outer packages simultaneously. This merging reduces the number of separate components and assembly steps required, thereby improving mass production efficiency while maintaining multi-point securing effectiveness.
Solution Approach 2:
The latching mechanisms are pre-configured on the inner package during its formation process, and the security card is pre-assembled with its tabs positioned for engagement. When the inner package is inserted into the outer package, the securing means automatically engage in a single motion, eliminating the need for multiple separate assembly operations and increasing production speed.

AI summary
A tamper-evident, child-proof package, having an outer package and having an inner package, the inner package being at least partially received in the outer package, and the inner package for opening and closing the package being disposed so as to be displaceable in the outer package, and the package has at least one securing structure as an anti-tamper feature for impeding or preventing the opening of the package, or the access to the products disposed in the inner package. The at least one securing structure is effective between the inner package and the outer package so as to impede or prevent the inner package being displaced in the outer package in order for the package to be opened.
