Single-Use Multi-Compartment Baby Formula Pouch for Aseptic Mixing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Convenient containers for holding powdered infant formula and ensuring aseptic mixing with liquid are lacking in existing technologies.
Innovation Solution
A multi-compartment pouch with separate chambers for powdered formula and liquid, featuring a frangible seal that breaks under pressure for mixing, and a silicone nipple pre-secured to a spout for direct feeding without assembly or sterilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate containers for powder and liquid are used, then mixing convenience is improved, but assembly complexity and sterilization requirements increase
Solution Approach 1:
The patent combines separate powder and liquid containers into a single integrated pouch with internal compartments. The powder chamber and liquid chamber are sealed together with a frangible seal between them, eliminating the need for separate containers and their assembly, while maintaining the convenience of mixing by simply breaking the internal seal.
2Ease of operation
If pre-assembly of nipple and spout is performed, then ease of use is improved, but sterilization complexity increases
Solution Approach 1:
The patent employs a disposable single-use pouch that eliminates the need for repeated sterilization. The nipple is pre-secured to the spout in a sterile manner during manufacturing, and the entire assembly is discarded after one use, avoiding the need for complex home sterilization procedures while maintaining ease of use.
3Productivity
If frangible seal is used for mixing, then mixing speed is improved, but seal reliability before use deteriorates
Solution Approach 1:
The frangible seal is pre-positioned and pre-sealed during manufacturing to ensure reliable separation of powder and liquid chambers before use. The seal is designed with specific structural features (such as scored lines or weakened sections) that ensure it breaks reliably and quickly when pressure is applied during use, thus maintaining both pre-use reliability and post-activation mixing speed.

Function Achieved in This Case
Ensures aseptic mixing and convenient use of infant formula by combining dry formula and sterile water in a sealed package, maintaining sterility and extending shelf-life through nitrogen purging and clean-break seal.
Implementation Method 1
the frangible seal is broken when pressure is applied allowing the powder and the liquid to mix
Implementation Method 2
maintaining sterility and extending shelf-life through nitrogen purging

AI summary
A single-use, multi-compartment infant formula pouch is disclosed. The pouch includes a substantially flat, flexible body formed from a laminate material including an aluminum foil layer. It contains two internal compartments: one pre-filled with powdered infant formula and the other with purified or distilled water. The compartments are separated by a frangible heat seal that ruptures upon applied pressure, enabling mixing just prior to use. The pouch also includes an integrated silicone nipple sealed beneath a removable cap, with the nipple secured into a spout by an internal locking ring to prevent user disassembly. During manufacturing, the pouch is filled under sterile conditions, including nitrogen gas injection and humidity control, to ensure long shelf life and inhibit microbial growth. The result is a tamper-evident, ready-to-feed, disposable system requiring no additional components or assembly.
