Card-Based Infant Nutrition Packaging With Hermetic, Insect-Tight Reclosure
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing card-based packages for sensitive materials like powdered infant nutrition lack effective re-closable elements that maintain hermetic sealing and are susceptible to insect ingress, failing to meet the stringent requirements of infant nutrition packaging, especially in humid environments.
Innovation Solution
A card-based package design featuring a collar portion and lid portion, both made of card-based material, with a secure joint and additional functionalities like a gasket and locking mechanism to ensure insect-tight closure and repeated use, utilizing a collar portion height of 10-70 mm and a lid with a folded seam for enhanced sealing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic-based materials are used for re-closable elements, then hermetic sealing and protection against insect ingress are improved, but environmental impact and recyclability worsen
Solution Approach 1:
The patent changes the material parameters by using card-based material with specific physical properties (rigidity, barrier properties) to replace plastic while maintaining hermetic sealing functionality through design modifications
Solution Approach 2:
The patent employs composite card-based materials that combine multiple layers or treatments to achieve both environmental friendliness and functional performance for hermetic sealing and insect protection
2Object-affected harmful factors
If card-based material is used for re-closable lids, then environmental friendliness and recyclability are improved, but hermetic sealing and protection against insect ingress worsen
Solution Approach 1:
The patent divides the package into distinct segments (container portion, collar portion, lid portion) where each serves a specific function, allowing the card-based material to be optimized for environmental friendliness while the joint design provides insect protection
Solution Approach 2:
The collar portion acts as an intermediary element between the container and lid, providing a transition zone that enhances the sealing capability and insect protection of the overall card-based structure
3Reliability
If a collar portion is added between the container and lid, then insect-tight closure and repeated use capability are improved, but device complexity increases
Solution Approach 1:
The collar portion is designed to perform multiple functions simultaneously: providing structural support, enabling insect-tight closure, facilitating repeated opening/closing, and maintaining hermetic sealing, thereby justifying the added structural element through multi-functionality
4Ease of manufacture
If card-based material is used instead of plastic, then recyclability in paper streams is improved, but barrier protection and hermetic sealing worsen
Solution Approach 1:
The patent modifies the physical and chemical parameters of card-based material through laminations, coatings, or material treatments to achieve barrier properties comparable to plastic while maintaining recyclability in paper streams

AI summary
A card-based package for powdered infant nutrition, comprises a container portion, the container portion defining an interior space for receiving the powdered infant nutrition and having a base and a sidewall extending to an upper peripheral edge for receiving a removable seal for hermetically sealing the container portion prior to use. The package further comprises a collar portion and a lid portion. The collar portion is connected to and extends upwardly from the upper peripheral edge of the container portion and comprises a connection segment and an upper peripheral closure rim surrounding an access opening giving access to the interior space. The lid portion comprises a lid and a frame and forms a re-closable joint with the upper peripheral closure rim of the collar portion, allowing repeated and selective opening and closing of the access opening. The container portion, the collar portion and the lid portion all comprise card-based material.
