Book-Like Packaging Structure for Blister Pack Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blister pack packaging is vulnerable to damage and child access, leading to product contamination, displacement, and loss, especially with tobacco-based products that are hygroscopic and require child-resistant measures.
Innovation Solution
A book-like packaging structure with inner blister pack retainers and a cover that includes apertures for secure retention and display, formed from a single sheet of stock, providing a child-resistant and tamper-evident solution for packaging multiple tablets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If blister packs are made from thin plastic or laminate material, then convenience of use and ease of manufacture are improved, but vulnerability to impact and abrasion damage increases
Solution Approach 1:
The blister pack is nested within a rigid outer packaging structure that provides mechanical protection. The inner blister pack containing the tablets is placed inside a sturdy box or container that shields it from impact and abrasion during handling and transport, while maintaining the original blister pack's ease of manufacture.
Solution Approach 2:
The packaging system combines multiple materials with different properties: the thin plastic or laminate blister pack for flexibility and ease of manufacture, combined with a rigid outer packaging material for protection against damage. This composite packaging structure leverages the advantages of each material while compensating for their individual weaknesses.
2Ease of operation
If the backing layer is made frangible for easy tablet removal, then ease of operation is improved, but vulnerability to unintentional pack rupture increases
Solution Approach 1:
The backing layer is designed with differentiated properties: frangible in specific localized areas to allow easy tablet removal where needed, while maintaining structural integrity in other areas to prevent unintentional rupture. The frangibility is concentrated at designated break points rather than distributed throughout the entire backing layer.
Solution Approach 2:
The backing layer is segmented into frangible zones and non-frangible zones. The frangible portions are designed to break only at specific locations and under specific conditions (such as applied pressure on individual tablets), while the rest of the backing layer remains intact to protect the tablets from accidental damage.
3Reliability
If additional packaging elements are added for child resistance and information display, then protection and information provision are improved, but device complexity increases
Solution Approach 1:
Multiple functions are merged into a single integrated packaging structure. The child-resistant features, information display areas, and tablet protection functions are combined into one cohesive packaging design rather than separate components. This reduces overall complexity while maintaining all required functions.
Solution Approach 2:
The packaging structure is designed to perform multiple functions simultaneously: it provides child resistance through integrated locking mechanisms, displays required information on its surfaces, protects the tablets from damage, and maintains ease of tablet access. This multi-functional design avoids the need for separate components for each function.
