Dairy Package With Diagonal Welding Lines for Shape Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional packages for dairy products immersed in preserving liquid, such as mozzarella, tend to deform and become crushed due to their design, leading to instability and quality issues during packaging, storage, and display, especially when the product is hot and deformable.
Innovation Solution
A package design featuring a bag with diagonally oriented welding lines that progressively narrow towards the bottom, providing lateral support zones and a central support zone on the bottom, made from a multi-layer film that is thinner and more flexible than traditional rigid packages, allowing the product to maintain its shape and remain stable in a vertical position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional multi-layer film packages are used for dairy products, then the packages can be welded and sealed, but the packages tend to be compressed and squashed, causing deformation of the dairy product
Solution Approach 1:
The patent uses a flexible bag made of thin film material that can adapt to the shape of the dairy product while providing sufficient support. The flexible nature of the thin film allows it to conform to the product without causing deformation, unlike rigid packages. The film is thin enough to be flexible but sufficiently strong to maintain product shape during handling and storage.
Solution Approach 2:
The package design incorporates dynamic elements through the flexible film that can adapt its shape based on the product it contains. The bag can deform slightly to accommodate the product shape while maintaining overall structural integrity, providing a dynamic response to different packaging scenarios rather than a fixed rigid structure.
2Stability of the object's composition
If rigid packages with thick film are used to maintain vertical position, then the packages can stand upright, but the packages are very rigid and not suitable for deformable dairy products
Solution Approach 1:
The thin film bag provides a flexible container that can adapt to deformable dairy products while still achieving vertical stability through proper filling and sealing. The flexibility allows the package to conform to the product shape, preventing damage to deformable items, while the overall structure can maintain upright position during storage and display.
Solution Approach 2:
The patent changes the physical parameters of the packaging material by using thin film instead of thick rigid material. This parameter change transforms the package from rigid to flexible, enabling it to accommodate deformable dairy products while maintaining sufficient structural properties for vertical stability when properly filled.
3Adaptability or versatility
If thin flexible film is used for packaging, then the package is more adaptable to product shape, but the package cannot maintain vertical position and spills liquid
Solution Approach 1:
The thin flexible film bag achieves both adaptability to product shape and vertical stability through its flexible nature. The film conforms to the dairy product, providing support and maintaining shape, while the overall package structure can stand upright during storage and display without spilling liquid, combining the benefits of flexibility with functional stability.
4Productivity
If normal packages are used for hot deformable dairy products, then the packaging process is simple, but the product is crushed and deformed during packaging
Solution Approach 1:
The flexible thin film bag allows hot deformable dairy products to be packaged simply and quickly while maintaining product shape integrity. The flexibility of the film accommodates the deformable product during insertion, and the conforming nature of the bag provides immediate support that prevents crushing and deformation, achieving both high productivity and manufacturing precision.
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 effectively prevents deformation and crushing of dairy products, maintains their shape, and allows for stable vertical storage and display without spilling, even when the product is introduced while hot and deformable, using a thinner, more flexible material that self-stabilizes the product within.
Implementation Method 1
a multi-layer film comprising two or more layers of film, generally plastic, joined by suitable adhesion processes
Implementation Method 2
The welding can take place for example by heat-sealing or other current technique

AI summary
A package for dairy products, in particular solid or semi-solid dairy products, including a bag provided with at least one pair of lateral walls reciprocally joined by means of first welding lines and at least one bottom wall, so as to define a housing compartment. A dairy product is housed in the compartment defined inside the bag. The bag includes second welding lines made in correspondence with top parts of the bag and positioned on opposite sides of the bottom wall. The second welding lines are disposed diagonally with respect to the first welding lines and with respect to the bottom wall and configured and oriented so as to progressively narrow the housing compartment toward the bottom wall of the bag. The dairy product includes at least a central support zone on the bottom wall and the bag includes at least lateral support zones defined by the opposite top parts.
