Flexible Package Frame and Handle Seal for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Flexible packages used for disposable absorbent articles lack stability, often collapsing when opened and suffer from the risk of the handle tearing off when lifted, which affects both individual and pallet stability.
Innovation Solution
A flexible package design featuring a frame with a handle attached via a seal that ensures the handle is securely integrated with the frame, maintaining structural integrity and stability during use and stacking, while the handle's design allows for easy access and carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a flexible package is made from flexible material without additional support structures, then the package is easy to manufacture and has simple structure, but the package lacks stability and collapses when opened
Solution Approach 1:
The package structure is divided into distinct functional segments: a flexible bag body for containing products, a separate frame structure for providing stability, and an integrated handle for carrying. This segmentation allows each component to perform its specific function optimally while maintaining overall package stability without excessive complexity
Solution Approach 2:
The patent utilizes flexible material such as plastic film for the bag body while incorporating a frame structure that provides rigidity where needed. The flexible shell maintains ease of manufacture and product conformity, while the frame adds stability without requiring the entire structure to be rigid
2Ease of operation
If a handle is attached to the flexible package, then the package is easier to carry, but the handle may tear off from the rest of the package during lifting
Solution Approach 1:
The handle is merged with the frame structure rather than being separately attached to the flexible bag. The handle forms an integrated part of the frame, creating a unified load-bearing structure that eliminates the risk of handle detachment during lifting while maintaining ease of carrying
3Stability of the object's composition
If the frame structure extends upwardly from the top gusset, then the package maintains its shape and improves pallet stability, but the manufacturing process becomes more complex
Solution Approach 1:
The frame structure is formed as an integral part of the packaging process, with the frame extending upwardly from the top gusset in a predetermined configuration. This preliminary formation of the frame structure during manufacturing ensures pallet stability and shape maintenance without requiring additional complex assembly steps

AI summary
A flexible package being capable and being adapted for accommodating a multiplicity of absorbent articles. The package has a substantially parallelepiped-shape and further comprises a frame. The frame is completely surrounding the top gusset extending upwardly and substantially orthogonally from the top gusset. The flexible package also comprises a handle extending over the top gusset. It is a further object of the present invention to provide a method of manufacturing a flexible package.
