Heat Insulating Container With Rubber-Insulated Handle
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional food containers become hot during microwave heating, making them inconvenient to handle and potentially scalding when removed from the oven, as heat is transferred from the heated food to the container.
Innovation Solution
An anti-scald heat insulating container design featuring a bottom box and surrounding wall with a handle portion separated from the bottom box by a rubber strip for insulation, a lid with snap-fits and rubber strip for sealing, and a flange to prevent direct contact and heat transfer, allowing safe immediate removal from the microwave.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the container is made of conventional material without insulation structure, then the container can be easily manufactured and has simple structure, but the container becomes hot during microwave heating making it inconvenient to handle and potentially scalding
Solution Approach 1:
The container is divided into three main segments: the bottom box for holding food, the surrounding wall providing thermal insulation, and the handle portion extended from the junction area. This segmentation allows the hot bottom box to be isolated from the handle, enabling safe handling without requiring the entire container to be cooled.
Solution Approach 2:
The surrounding wall acts as an intermediary thermal barrier between the heated bottom box and the外部环境. This insulating layer prevents direct heat transfer to the handle portion, allowing the user to safely hold the container immediately after microwave heating without scalding.
2Productivity
If the container allows immediate removal from microwave, then the heating process is efficient and time-saving, but the user risks scalding from direct contact with hot surfaces
Solution Approach 1:
The surrounding wall serves as a thermal intermediary that blocks heat transfer from the bottom box to the handle portion. This allows the container to be removed immediately from the microwave while the handle remains cool enough for safe user contact, eliminating the scalding risk without compromising heating efficiency.
Solution Approach 2:
The container exhibits different thermal properties in different regions: the bottom box is designed to conduct and retain heat for efficient heating, while the handle portion is thermally isolated to maintain a safe temperature for user contact. This localized thermal management allows immediate removal without scalding risk.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design prevents scalding by creating a space barrier and enhancing heat insulation, enabling safe handling and immediate removal of the container from the microwave oven without cooling the contents.
Implementation Method 1
the handle portion is wrapped by a rubber strip
Implementation Method 2
a space barrier is thereby defined to prevent a user from being scalded by directly contact with the bottom box

AI summary
A heat insulating container includes a bottom box and a surrounding wall surrounding the bottom box. A top portion of the bottom box is open and connected with the surrounding wall. An inner space of the surrounding wall is connected with an inner space of the bottom box, an opening is defined by a top edge of the surrounding wall, a handle portion is downward extended from an external surface of a junction between the bottom box and the surrounding wall, the handle portion and the bottom box are arranged at interval and a rubber strip is arranged wrapping the handle portion. Thereby the user is avoided from directly contacting with the bottom box. Therefore, the heat insulating container could be immediately taken out of a microwave oven after heater by the microwave oven.
