Resealable Childproof Bag Closure with Intermittent Locking Profile
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Standard zip lock closure systems on resealable bags are inadequate in preventing minors from accessing cannabis, as children can easily open these bags, posing a risk of harmful ingestion.
Innovation Solution
A resealable childproof bag system featuring interlocking locking members with a gap or interruption that facilitates adult access while preventing children from opening the bag, utilizing thermoplastic materials and specific interlocking profiles to ensure an airtight seal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a standard zip lock closure system is used, then the bag is easy to open and close, but children can easily open the bag and access the contents
Solution Approach 1:
The closure system is divided into multiple locking members (first locking member, second locking member, third locking member, fourth locking member) that work together to create a more complex opening mechanism. Each locking member has specific interlocking features that require coordinated action to disengage, preventing children from opening the bag while maintaining adult accessibility.
Solution Approach 2:
The closure system acts as an intermediary mechanism between the bag interior and exterior. The multiple locking members with interlocking profiles create a barrier that mediates access, requiring specific knowledge and coordinated action to open, thus protecting children while allowing authorized access.
2Reliability
If multiple locking members are added to prevent children from opening, then childproof capability improves, but device complexity increases
Solution Approach 1:
Multiple locking members are merged into a single integrated closure system that operates as one cohesive unit. The locking members are positioned along the same sealing edge and work together through coordinated interlocking, reducing overall complexity compared to having separate locking mechanisms.
Solution Approach 2:
The closure system performs multiple functions simultaneously: it provides sealing, childproof protection, and controlled access. The interlocking profiles of the locking members serve both to seal the bag and to prevent child access, eliminating the need for separate mechanisms.
3Reliability
If the locking members are tightly interlocked to prevent child access, then childproof capability improves, but the ease of opening for adults decreases
Solution Approach 1:
The locking members feature asymmetric interlocking profiles with distinct male and female portions. The first and third locking members have male interlocking profiles that engage with female profiles on the opposing side, creating a configuration that is easy to disengage with adult dexterity but difficult for children to manipulate.
Solution Approach 2:
The closure system transitions from a static tightly-interlocked state to a dynamic opening state through coordinated movement of the locking members. The interlocking profiles are designed to release through a specific motion pattern that requires adult coordination but provides clear tactile feedback during opening.

AI summary
The present disclosure relates to a method for opening a resealable childproof bag designed to provide an effective yet child-resistant access mechanism. The bag includes first and second sidewalls, each with an upper portion, and first and second locking members attached to the inner surfaces of the respective sidewalls. The method includes locating an interruption in the first locking member, which is interlocked with the second locking member. The method further includes applying outward forces to the locking members at the interruption to initiate a rotating motion facilitated by the unattached upper portion of the first sidewall. This motion enables the disengagement of the locking members, allowing the bag to be opened. The interruption is discreetly designed to be non-obvious to children, ensuring childproof functionality, while adults can easily identify and operate the opening mechanism.
