Dairy Packaging Shells for Finger-Free Cheese Consumption
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing food packaging for dairy and cheese products requires users to touch or use cutlery to consume the product after opening, which is inconvenient for adults and does not allow for easy access without fingers.
Innovation Solution
A packaging design featuring two hollow shells with a depth greater than their thickness, allowing the product to be consumed by holding one shell without touching the fingers, and a manufacturing method involving thermoforming and sealing of plastic shells to create a metering neck for filling and easy opening.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cheese products are packaged in traditional containers (aluminum foil, rigid or semi-rigid plastic), then the product is protected and易于 storage, but the user must use fingers or utensils to consume the product after opening
Solution Approach 1:
The packaging is divided into two separate hollow shells that can be separated from each other. One shell retains the cheese product while the other can be used as a handling tool, eliminating the need for fingers to touch the food.
Solution Approach 2:
One of the hollow shells serves as an intermediary tool between the user's hand and the cheese product. The user holds this shell to access and consume the product without direct finger contact.
2Ease of operation
If cheese products are presented on sticks or in shells for finger-free consumption, then adults can consume without touching the product, but the packaging structure becomes more complex
Solution Approach 1:
The hollow shells serve multiple functions: they protect the cheese product during storage, provide a separation mechanism for opening, and one shell becomes a handling tool for finger-free consumption. This multi-functionality reduces the need for additional separate components.
Solution Approach 2:
The two hollow shells are designed to fit together in a nested configuration, with one shell containing the other during storage and transport. This nesting minimizes the overall packaging footprint while maintaining the finger-free consumption capability.
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
Enables convenient consumption of dairy or cheese products without using fingers, providing easy access and maintaining product integrity with a secure, one-way separation mechanism for adults and children.
Implementation Method 1
a) thermoforming at least one roll of plastic film so as to obtain two hollow shells
Implementation Method 2
b) sealing the two shells along a joint plane so as to form a single internal space

AI summary
The invention relates to a food packaging (10), particularly for milk or cheese products (20), comprising two hollow shells (12, 14), each of the two shells (12, 14) having a plane of symmetry (S) and extending to a predetermined depth (p12, p14) and having predetermined thickness (e), the joining plane (16) being substantially orthogonal to the plane of symmetry (S), said packaging being characterized by the fact that at least one of the two shells (12, 14) has a depth (p12, p14), measured in said plane of symmetry (S), that is greater than or equal to its thickness (e) measured in the joining plane (16). The invention also relates to a method of producing a food packaging (10), in particular for milk or cheese products (20).
