Praline Packaging Interlocking Shells
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional praline packaging fails to effectively protect chocolates from mechanical damage and maintain freshness while being hygienic, and is often costly and difficult to produce.
Innovation Solution
A spherical praline packaging design featuring hemispherical indentations and elevations in PET material, with a non-positive and/or positive connection edge for airtight sealing, allowing easy separation and attractive presentation, eliminating the need for additional packaging foil and sealants.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If conventional praline packaging uses individual wrapping with packaging film or tray-like shells, then mechanical protection is provided, but the packaging becomes complex and costly to produce
Solution Approach 1:
The packaging is divided into an upper housing shell and a lower housing shell that can be separated. Each shell has recesses and protrusions that interlock to provide mechanical protection while allowing easy separation and reassembly, reducing packaging complexity
Solution Approach 2:
The pralines are nested within the interlocking housing shells, with each shell providing a protective layer. The upper and lower shells nest together to form a complete protective structure that is both simple and effective
2Reliability
If conventional packaging uses additional packaging foil and sealants, then airtight sealing is achieved, but the production process becomes more complex and costly
Solution Approach 1:
The patent removes the need for additional packaging foil and sealants by integrating the sealing function directly into the housing shells through precision-machined interlocking surfaces with recesses and protrusions that create airtight seals
Solution Approach 2:
The sealing function is merged with the structural function of the housing shells. The interlocking surfaces of the upper and lower shells serve both as structural connectors and as airtight seals, eliminating the need for separate sealing components
3Strength
If pralines are embedded in tray-like shells with matching depressions, then mechanical protection is improved, but removal of chocolates becomes difficult
Solution Approach 1:
The packaging transitions from a fixed, rigid structure to a dynamic system where the upper and lower housing shells can be easily separated and reassembled. This allows chocolates to be removed by simply separating the shells rather than extracting them from fixed depressions
4Reliability
If conventional packaging uses multiple components and additional materials, then protection is enhanced, but cost increases
Solution Approach 1:
The patent eliminates unnecessary components such as packaging foil, sealants, and complex tray structures, retaining only the essential upper and lower housing shells that provide both protection and sealing functions
Solution Approach 2:
The housing shells serve multiple functions simultaneously: mechanical protection, airtight sealing, and easy separation/reassembly. This multi-functionality reduces the need for multiple separate components, lowering production costs while maintaining protection effectiveness
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 packaging provides robust mechanical protection, maintains freshness, and offers an aesthetically pleasing presentation while being cost-effective and easy to produce, ensuring chocolates remain fresh and protected without additional packaging.
Implementation Method 1
The edges of the housing plates are provided with a peripheral non-positive and/or positive connection edge which keeps the two housing shells closed. In addition to the connection function, the edge also has a sealing function, so that the chocolates are packed airtight.
Implementation Method 2
The flat abutting sections of the housing shells are preferably smooth so that air is prevented from entering the capsule.
Implementation Method 3
The two shells also easily stick to each other due to electrostatic charging.

AI summary
In order to create a chocolate packaging (100) for chocolates, in particular for truffle chocolates, with a lower housing shell (10) consisting of a first housing plate (12) with recesses (13) and with an upper housing shell (11) consisting of a second housing plate (14) with protrusions (15), which protects the chocolates mechanically and hygienically and is easy and inexpensive to manufacture, it is proposed that, when the chocolate packaging is closed, the first and the second housing plates (12, 14) abut each other flat in such a way that each recess (13) of the lower housing shell (10) corresponds to each protrusion (15) of the upper housing shell (11) and thus forms a capsule (16) for each chocolate.
