Packaged Article Air Sealed Portion for Stable Hot Water Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing packages that are heated in hot water are difficult to safely remove without splashing or burning, and they often do not allow for uniform heating of contents.
Innovation Solution
A package with a laminate structure featuring a base layer, barrier layer, and sealant layer, where an air sealed portion is integrated into the seal portion, allowing air to be enclosed and providing a float effect that enables stable removal from hot water and uniform heating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the package is held by chopsticks to take out from boiled water, then the hand is protected from burning, but the chopsticks may slip and it is difficult to hold the package
Solution Approach 1:
The air sealed portion acts as an intermediary element between the package body and the chopsticks. It provides a dedicated catching structure that mediates the interaction between the user's tool (chopsticks) and the package, ensuring stable holding while maintaining hand protection from hot water
2Ease of operation
If the package is held with a bare hand to take out from boiled water, then the package can be easily gripped, but the hand or fingertips may be burned by boiled water or splashes
Solution Approach 1:
The air sealed portion serves as a mediator that allows easy gripping while preventing direct contact with hot water. It creates a safe interaction zone where users can grip the package without their hands being exposed to burning risks from boiled water or splashes
3Adaptability or versatility
If the package is heated in hot water, then it can be used outdoors without microwave oven or pot, but the package floats in water making it difficult to insert and catch the chopstick in the hole
Solution Approach 1:
The air sealed portion functions as a counterweight element that offsets the package's tendency to submerge. By creating a buoyant force, it counteracts gravity's pull on the package, causing it to float or remain partially exposed, thereby making the air sealed portion accessible for chopstick insertion and catching operations
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 package can be safely and easily removed from hot water, with the air sealed portion acting as a float to facilitate pinching and ensuring uniform heating of contents.
Implementation Method 1
The seal portion has one air sealed portion (6) in which air is enclosed
Implementation Method 2
circumferential edges being heat-sealed

AI summary
An object of the present invention is to provide a package that can be safely taken out from boiled water with stability when heated in hot water, and that can allow contents therein to be uniformly heated. A package (1) is provided which includes a laminate having a base layer, a barrier layer, and a sealant layer, and has a seal portion formed by the sealant layers of the laminates being disposed so as to oppose each other, and circumferential edges being heat-sealed. The seal portion has one air sealed portion (6) in which air is enclosed, and a distance (d) from an outer edge of the air sealed portion to an outer edge of the package is greater than or equal to 2 mm.
