Child-Resistant Packaging Housing with Node-Slot Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging containers fail to effectively prevent access by children while remaining accessible to senior citizens, and they do not adequately address the need for environmental sustainability, security against theft, and safe opening mechanisms.
Innovation Solution
A child-resistant packaging container design that securely retains a slidable blister card within a housing, requiring multiple steps to access, using a tear-resistant material and a specific folding mechanism to allow senior-friendly access while preventing removal by children, and incorporating features like a node and slot system for secure retention and easy return of the blister card.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional packaging containers are used to secure contents, then child access is prevented, but senior citizen access becomes difficult
Solution Approach 1:
The packaging employs a dynamic opening mechanism where the blister card can slide between locked and unlocked positions. The housing structure allows controlled movement through a multi-step process that adapts to different user capabilities, enabling both child resistance and senior accessibility through the same dynamic system
Solution Approach 2:
The packaging is divided into distinct functional components: the housing structure, the slidable blister card, and the node-slot locking mechanism. This segmentation allows each component to perform its specific function independently while working together to achieve both child protection and senior-friendly operation
2Ease of manufacture
If simple packaging structures are used, then ease of manufacture is improved, but security against theft and misuse is reduced
Solution Approach 1:
The packaging incorporates pre-designed fold lines and panel configurations in the blank structure that guide the assembly process. The node and slot features are pre-formed during manufacturing, enabling the security function to be built into the structure before final assembly, thus maintaining ease of manufacture while achieving enhanced security
Solution Approach 2:
The housing is formed from a paper-based material that provides both structural integrity and tear resistance. This composite approach combines the benefits of paper (ease of manufacture, environmental friendliness) with engineered structural features (security against theft and misuse)
3Reliability
If multiple retention points are used to secure the blister card, then security is improved, but device complexity increases
Solution Approach 1:
The node and slot mechanism serves multiple functions simultaneously: it locks the blister card in place during storage, guides the sliding motion during opening, and provides tactile feedback for proper positioning. This multi-functionality achieves secure retention without proportionally increasing device complexity

AI summary
A childproof and senior friendly packaging container having a housing that defines a chamber for removably receiving a blister card or sheet. The blister card includes a blister or node on its end that is designed to engage a pair of slots within the sleeve of the housing to retain the blister card within the housing in a stored position and an extended position. The node may include a sloped rear surface to allow the blister card to be returned to a stored position. Squeezing the sides of the housing about the interior slot biases both the top panel of the housing and the panels defining the slot to release the node from the slot to allow the blister card to be withdrawn.
