Child-Resistant Box With Overlapping Flaps And Fragment Release
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current childproof packaging for pharmaceuticals is either bulky or not designed to prevent access via alternative routes, posing a safety risk as children can easily open them by tampering with the packaging.
Innovation Solution
A child-resistant box design featuring overlapping flaps that are adhesively attached to prevent access, with a grid structure of weakening lines that release fragments upon tampering, delaying access and discouraging children from persisting in opening the box.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If childproof packaging uses traditional lids or caps requiring special handling, then child access is prevented, but the packaging becomes bulky and less portable
Solution Approach 1:
The packaging is divided into multiple flaps (first flap, second flap, third flap) that can be separately manipulated. The first flap covers the opening, while the second and third flaps overlap to secure the first flap in place, creating a segmented closure system that maintains childproof capability without requiring bulky external lids or caps.
2Ease of operation
If packaging provides easy access to contents, then portability and convenience are improved, but children can easily access the contents posing a safety risk
Solution Approach 1:
The packaging is pre-configured with weakening lines on the first flap and interlocking overlap patterns between flaps before use. These preliminary structural features ensure that when a child attempts to open the packaging, the first flap breaks along predetermined lines and the overlapping flaps resist separation, delaying access without requiring complex active locking mechanisms.
3Ease of manufacture
If packaging uses simple closure flaps, then ease of manufacture is improved, but tampering evidence is difficult to detect
Solution Approach 1:
The first flap is differentiated from the other flaps by incorporating weakening lines at specific locations, creating a local structural variation. This localized feature causes the first flap to break in a distinctive manner upon tampering, providing clear visual evidence that the packaging has been opened, while the rest of the packaging structure remains simple and easy to manufacture.
4Reliability
If packaging prevents access via the intended route, then childproof capability is improved, but alternative routes are not addressed allowing easy access
Solution Approach 1:
The overlapping flap configuration serves multiple functions simultaneously: the second and third flaps overlap to secure the first flap, preventing access through the intended opening route, while also creating additional barriers that block alternative access routes. The interlocking structure ensures that any attempt to access contents must overcome multiple flap layers, providing comprehensive protection against various opening methods.

AI summary
A box enclosing a chamber for carrying at least one object, such as a quantity of objects, is provided. The box comprises at least one wall, wherein said wall comprises a pair of overlapping flaps. The outer flap of said pair is adhesively attached to the inner flap of said pair to prevent access to the object(s) within the box. The outer flap is also arranged to release fragments without providing access to said objects if being tampered with. The application also includes a blank which may be folded to obtain a box.
