Casket-Style Confectionery Packaging Inversion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing box-type packages with lids that open like a casket for foodstuff products face production challenges due to the need for precise internal space matching the support's dimensions, leading to aesthetic issues and inefficiencies in paper material usage.
Innovation Solution
The package design reverses the conventional configuration by using a paperboard casing only as the lid and a polymeric support to form the container, with the support defining the outer walls and the casing providing anchorage, ensuring a stable and aesthetically pleasing assembly with reduced paper material usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the paperboard casing forms a box with precise internal space matching the support dimensions, then aesthetic appearance is improved, but manufacturing complexity and material waste increase
Solution Approach 1:
The patent inverts the conventional configuration by making the polymeric support form the outer container walls instead of being an inner insert, while the paperboard casing becomes only the lid. This reversal eliminates the need for precise internal space matching and reduces manufacturing complexity while maintaining aesthetic appearance.
Solution Approach 2:
The package is segmented into distinct functional components: the polymeric support forms the container structure with cell definitions, while the paperboard casing serves as the removable lid. This segmentation allows independent optimization of each component and simplifies the overall manufacturing process.
2Shape
If the paperboard casing forms a box with precise internal space matching the support dimensions, then aesthetic appearance is improved, but paper material consumption increases
Solution Approach 1:
By inverting the conventional configuration and using the polymeric support to form the outer container walls, the patent eliminates the need for a large paperboard box, thereby reducing paper material consumption while maintaining aesthetic appearance through the support's own structural design.
Solution Approach 2:
The paperboard material is used locally only where needed for the lid and anchorage features, rather than forming the entire box. This localized use of paper material reduces overall consumption while maintaining aesthetic appearance in the visible portions of the package.
3Ease of manufacture
If the support is set inside a pre-formed box, then assembly is simplified, but empty spaces and aesthetic issues occur
Solution Approach 1:
The patent inverts the conventional arrangement by having the support form the outer container walls rather than being inserted into a pre-formed box. This eliminates empty spaces and aesthetic issues while maintaining assembly simplicity through the integrated design of the support and lid anchorage features.

AI summary
A box-type package with a lid that opens like a casket, designed to contain foodstuff products, in particular confectionery products, the package comprising: - a paperboard casing (2) defining a base (4) and a lid (6) connected to the base (4) so as to be able to oscillate between a position of opening and a position of closing of the package; and - a support (8) made of polymeric material defining a plurality of cells designed to receive the products, which is carried by the base (4); the package being characterized in that the base of the casing comprises a bottom (41) and at least one tab (42), which can be folded with respect to the bottom, and in that the support (8), which is set on the aforesaid bottom, comprises at the bottom a slot (81) within which the at least one tab (42) is inserted, for connecting the support to the casing in a configuration in which the support defines outer side walls of the container of the box-like package.
