Container for retort food
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing containers for retort food face challenges in ensuring effective sterilization and preventing overflow, while also adhering to packing space ratio regulations, due to insufficient depth leading to inefficiencies in retort processing and increased waste from individual packaging.
Innovation Solution
A container design featuring a container body with a recessed bowl part and an inner cap with a cap tray part that divides the space into upper and lower sections, utilizing a three-dimensional rib structure on the cap tray part for enhanced sealing and a multi-layer structure for easy peeling, which reduces the distance between the retort atmosphere and food, preventing overflow and satisfying packing space ratio regulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the depth of the container is increased to prevent overflow, then overflow prevention is improved, but sterilization efficiency deteriorates due to large gap between food and cap
Solution Approach 1:
The container is divided into two functional parts: the container body for holding food and the inner cap that can be positioned at different depths. The inner cap includes a cap tray part that sits inside the container body, creating segmented functional zones that allow both overflow prevention and effective sterilization.
Solution Approach 2:
The inner cap acts as an intermediary element between the food and the container opening. It provides a barrier that prevents overflow while its positioning within the container body ensures that the food remains in close proximity to the cap for effective sterilization during retort processing.
2Object-affected harmful factors
If the depth of the container is increased to prevent overflow, then overflow prevention is improved, but packing space ratio deteriorates making it difficult to satisfy regulations
Solution Approach 1:
The inner cap is nested inside the container body, with the cap tray part positioned within the inner space of the container bowl part. This nested configuration allows the overflow prevention function to be achieved without increasing the overall container depth, thereby maintaining compliance with packing space ratio regulations.
3Adaptability or versatility
If individual packaging materials are used for instant rice products, then product variety and convenience are improved, but waste generation increases and disposal becomes inconvenient
Solution Approach 1:
The inner cap and container body are designed to be integrated through thermal fusion, combining what would traditionally be separate packaging elements into a unified structure. This merging reduces the number of separate packaging materials that need to be disposed of, while still allowing for different food products to be packaged.
Solution Approach 2:
The container design with the inner cap serves multiple functions: it prevents overflow, facilitates sterilization, and provides a unified packaging structure that reduces waste. This multi-functional design allows the same basic structure to be used for various instant rice products, reducing the need for specialized packaging for each product type.
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 container achieves effective sterilization during retort processing, prevents food overflow, and simplifies packaging disposal, while adhering to regulatory packing space ratios by optimizing the depth and structure of the container and inner cap.
Implementation Method 1
when thermal fusion is performed in a state in which the cap flange part is placed on the container flange part, the lower space inside the container bowl part is sealed

AI summary
The present disclosure relates to a container for retort food and, more specifically, to a container for retort food including: a container body in which food may be input and stored; and an inner cap covering the container body. The inner cap covering the container body has a predetermined depth, and thus, effective sterilization may be performed during a retort processing process, overflow of the food in the container body may be prevented, and there is an advantage in satisfying regulations regarding a packing space ratio.
