Frozen Confection Packaging Blank Leakage Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current frozen confection packaging for in-home products often requires both primary and secondary packaging, leading to waste and leakage issues during transportation, especially for high-water content or coated products, as traditional primary packaging is not waterproof and can fail to prevent melting products from leaking.
Innovation Solution
A frozen confection packaging blank with four or more flaps and an insert panel, optionally with apertures and separator panels, is used to create a robust, single-item primary packaging that provides structural protection and leakage prevention, allowing for transportation without significant leakage regardless of orientation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional primary packaging is used for frozen confections, then the packaging is simple and easy to manufacture, but the packaging is not waterproof and allows leakage during transportation
Solution Approach 1:
The packaging structure is segmented into multiple functional flaps (front base flap, front lid flap, back base flap, back lid flap, and side flaps) that work together to create a waterproof containment system. Each flap serves a specific purpose in sealing the container, transforming a single-layer simple structure into a multi-component reliable system that prevents leakage while maintaining manufacturability.
Solution Approach 2:
The packaging design nests multiple flaps within each other to create overlapping seals. The flaps are arranged so that they nest together when folded, forming a waterproof barrier system where each flap contributes to the overall containment, allowing the structure to achieve high reliability through layered protection rather than a single complex component.
2Reliability
If both primary and secondary packaging are used for in-home products, then structural protection is provided, but packaging waste increases and recyclability decreases
Solution Approach 1:
The invention merges the functions of primary packaging (leakage prevention) and secondary packaging (structural protection) into a single integrated container structure. The robust multi-flap design provides both waterproof containment and structural integrity, eliminating the need for separate packaging layers and thereby reducing packaging waste while maintaining protective functionality.
Solution Approach 2:
The packaging container is designed to perform multiple functions simultaneously: it acts as both primary packaging (preventing leakage through waterproof flaps) and secondary packaging (providing structural protection during transport). This multi-functional design allows a single packaging item to replace what traditionally required two separate packaging items, reducing overall waste.
3Reliability
If the packaging base is designed with a fold structure, then the packaging is easy to manufacture, but the base is not water-proof and allows leakage
Solution Approach 1:
The base structure is segmented into multiple components: a front base flap, a back base flap, and side flaps that connect them. Instead of a single fold structure, the base is divided into overlapping segments that create waterproof seals when assembled, maintaining ease of manufacture through simple folding and tucking actions while achieving reliable waterproofing.
Solution Approach 2:
The side flaps act as intermediary elements that connect the front and back base flaps, creating a continuous waterproof barrier across the base. These intermediary flaps bridge the gap between opposing flaps, ensuring that the entire base structure becomes waterproof without requiring complex manufacturing processes.
4Reliability
If corner flaps are added to the packaging, then leakage prevention is improved, but the packaging structure becomes more complex
Solution Approach 1:
The corner protection function is segmented into dedicated corner flaps that are integrated with the side flaps. These corner flaps specifically address leakage at the corners where stress concentrates, dividing the waterproofing function into specialized components that enhance reliability without requiring a complete redesign of the entire flap system.
Solution Approach 2:
The corner flaps are merged with the side flaps to form an integrated sealing system. Rather than adding completely separate corner components, the design combines corner protection functionality with the existing side flap structure, achieving enhanced leakage prevention while minimizing increases in overall structural complexity.
