Composite Food Container With Glass Insert for Microwave Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current food storage containers either lack microwave safety due to chemical leaching concerns with plastic or are prone to breakage and heat hazards with glass, failing to combine the advantages of both materials effectively.
Innovation Solution
A composite food storage container design featuring a polymer outer container that accommodates a glass inner container, providing protection from breakage and chemical leaching, with shock-absorbing ribs and a non-slip surface, and a lid that engages securely for safe handling and use in microwave ovens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If plastic food storage containers are used, then they can be used in microwave ovens and are resistant to damage, but chemicals in the plastic may leach into the food
Solution Approach 1:
The container system is divided into two separate components: an outer plastic container and an inner glass container. This segmentation allows each material to serve its optimal function - the plastic outer container provides microwave safety and impact resistance, while the glass inner container prevents chemical leaching by directly contacting the food.
Solution Approach 2:
The glass container is nested inside the plastic container, creating a composite structure where the outer plastic container protects the inner glass container from breakage, while the glass container ensures food safety by preventing chemical leaching during microwave heating.
2Reliability
If glass food storage containers are used, then they can be used in microwave ovens, but glass is easily breakable and can become too hot to handle
Solution Approach 1:
The outer plastic container acts as a pre-established protective cushion around the glass container, absorbing impact forces before they can reach the glass and cause breakage. This beforehand protection allows the glass container to be used in microwave ovens without the usual breakage concerns.
Solution Approach 2:
The system combines two different materials - plastic and glass - each contributing their advantageous properties. The plastic outer container provides impact resistance and thermal insulation, while the glass inner container provides microwave safety and chemical inertness, creating a composite solution that overcomes the limitations of either material alone.
3Reliability
If glass containers are used, then they can be used in microwave ovens, but they become too hot to easily handle
Solution Approach 1:
The outer plastic container serves as an intermediary between the user's hand and the hot glass container. During microwave heating, the plastic outer container absorbs and insulates the heat, allowing users to safely handle the container after heating without direct contact with the hot glass surface.

AI summary
A composite food storage container combines the advantages of glass and polymer while avoiding their disadvantages. A composite food storage container may include an outer polymer container that is configured to accommodate a glass container within the polymer container. Since the food does not contact the polymer, there are no potential concerns with chemicals leeching into the food. Since the glass is surrounded by the polymer container, the glass is protected from breakage and the composite food storage container does not become too hot to easily and safely handle upon removal from a microwave oven.
