Packaging Body With Angular Opening For Medical Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packaging bodies for medical items like guide wires ensure sealing strength but are difficult to open, posing a challenge in both storage and transportation.
Innovation Solution
A packaging body design featuring a sticking region with a mountain-like angular opening, comprising non-sticking and sticking portions, where the width and angle of the opening allow for easy opening while maintaining sealing strength, achieved through heat-sealing of sheet materials with specific angular and width configurations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If the entire peripheral edges of the sheet materials are sealed with substantially the same width, then the sealing strength of the packaging body is sufficiently ensured, but the packaging body cannot be easily opened when the guide wire storage item is taken out
Solution Approach 1:
The sealing structure is segmented into multiple regions with different functions: a first sealing region with substantial sealing for strength, and a second sealing region with reduced sealing for easy opening. This segmentation allows the packaging body to simultaneously achieve both strong sealing and easy opening capabilities.
Solution Approach 2:
Different sealing qualities are applied to different parts of the packaging body. The first sealing region maintains substantial sealing width for strength, while the second sealing region has reduced sealing width for easy opening. This local differentiation resolves the contradiction between overall sealing strength and localized ease of opening.
2Ease of operation
If the packaging body is designed for easy opening, then the usability is improved, but the sealing strength may be compromised affecting transportation safety
Solution Approach 1:
The sealing structure is divided into functional segments where only the second sealing region has reduced sealing for easy opening, while the first sealing region maintains full sealing strength. This ensures that transportation safety is not compromised while achieving easy opening functionality.
Solution Approach 2:
The reduced sealing width is applied locally only to the second sealing region where opening is needed, while the first sealing region maintains substantial sealing. This localized approach preserves overall sealing strength while enabling easy opening at specific locations.

AI summary
A packaging body includes first and second sheet members superimposed on each other, and a sticking region formed on an outer periphery of the first and second sheet members. The sticking region has an opening portion in at least one part of the sticking region. The opening portion has an angled, convex shape and includes (i) a non-sticking portion in which the first and second sheet members are not stuck together and (ii) a plurality of first sticking portions that sandwich the non-sticking portion and in which the first and second sheet members are stuck together.
