Medical Package Top Shell Stiffener for Sealing Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing medical package designs face challenges in reliably applying sealing strips without deforming the opening zone, requiring specific shaped openings and additional backing parts for stiffness, which limits versatility and ease of use.
Innovation Solution
A package design featuring a top shell with a stiffener element and a connection portion connected by a hinge, allowing the sealing strip to be applied over the entire length of the cap and connection portion edges without deforming the opening zone, enabling reliable sealing and compatibility with various bottom shell shapes and sizes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a sealing strip is applied to the opening zone of the package, then sealing reliability is improved, but the opening zone may be deformed due to lack of stiffness
Solution Approach 1:
The patent applies a stiffener element specifically to the connection portion of the top shell, which is the local area requiring additional stiffness during sealing. This localized reinforcement provides the necessary structural support at the opening zone without requiring the entire package to be more rigid, thereby enabling reliable sealing strip application while preventing deformation of the opening zone.
2Stability of the object's composition
If the top shell is made with a specific shaped opening zone to provide stiffness, then sealing stability is improved, but the package versatility is reduced
Solution Approach 1:
The patent separates the stiffening function from the opening zone shape by introducing a distinct stiffener element that can be independently applied to the connection portion. This segmentation allows the opening zone to maintain a simple, versatile shape while the separate stiffener provides the necessary stability for sealing, enabling the same top shell design to work with various bottom shell shapes and sizes.
3Reliability
If a backing part is added to provide stiffness for sealing, then sealing reliability is improved, but the device complexity increases
Solution Approach 1:
The patent integrates the stiffener element directly into the connection portion of the top shell, merging the stiffening function with the existing structural component. This integration eliminates the need for separate backing parts while providing the necessary stiffness for reliable sealing, thereby improving sealing reliability without increasing device complexity.

AI summary
A package (2; 3) for an object is provided having a bottom shell (21; 31); a top shell (22; 32) having a closure portion (24; 34) referred to as a “cap”, and a connection portion (23; 33) in the form of a hollow body and connected to the closure portion (24) by a hinge (25) to enable the closure portion (24; 34) to tilt relative to the connection portion (23; 33) in order to release access to the inside of the bottom shell (21; 31) through the connection portion (23; 33). The connection portion (23; 33) is provided with a stiffener element (290; 390) and a sealing strip (4; 4′) connects together the edges (241, 231) of the cap (24; 34) and of the connection portion (23; 33) that face each other over the entire length of said edges. Said connection portion (23; 33) of the top shell (22; 32) and of the bottom shell (21; 31) are two parts that are fastened to each other, preferably by bonding.
