Confectionery Egg Packaging with Sealed Flanges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Confectionery packaging, such as confectionery eggs, face issues with non-stable shapes leading to rolling or tipping, lack of tamper evident closure, and inconsistent graphics, making them difficult to handle and display effectively.
Innovation Solution
The development of confectionery packaging with preformed parts and flexible films that conform to the shape of the product, featuring sealed flanges for tamper evident closure and repeatable graphics, along with stabilizing features like weights and curved designs to prevent rolling, and easy opening mechanisms through exaggerated flanges and fracture zones.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If a foil wrapper is wrapped around the confectionery egg to conform to its shape, then the packaging maintains the outer profile and provides a protective barrier, but the edges are not sealed and the packaging cannot provide tamper evident closure
Solution Approach 1:
The packaging is divided into two separate preformed parts (first part and second part) that are sealed together at flanges. This segmentation allows the packaging to maintain shape conformity while providing a sealed closure that prevents tampering, as the two parts must be separated to access the product.
Solution Approach 2:
The preformed parts are made from flexible materials that can conform to the shape of the confectionery product while maintaining structural integrity. This flexibility allows the packaging to adapt to the product shape while the sealed flanges provide the necessary tamper evident closure.
2Ease of manufacture
If a rectangular foil sheet is wrapped around the confectionery egg, then the packaging is easy to manufacture, but the graphics on the outer surface are inconsistent and do not form a continuous image
Solution Approach 1:
The packaging is divided into two preformed parts with flanges that can be sealed together. This allows graphics to be printed on flat surfaces of each part before forming, ensuring consistent and continuous imagery across the junction, while maintaining ease of manufacture through standardized forming processes.
3Shape
If the packaging has a non-stable shape that conforms to the product, then the packaging provides good product fit, but the packaging is prone to rolling or tipping when placed on a flat surface
Solution Approach 1:
The packaging incorporates asymmetric stabilizing features such as flattened portions or extended flanges that create a stable base on flat surfaces. These asymmetric elements counterbalance the non-stable conformal shape, allowing the packaging to stand upright without rolling or tipping while maintaining its shape conformity to the product.
4Reliability
If the flanges are sealed together to provide tamper evident closure, then the packaging security is improved, but the opening procedure becomes more complex
Solution Approach 1:
The sealing is concentrated at specific flange regions rather than along the entire perimeter. This extraction of the sealing function to discrete locations allows the packaging to maintain tamper evident closure while enabling easy opening by applying force at the unsealed portions or using the flanges as leverage points.

AI summary
A confectionery packaging is provided comprising a first part formed from a preformed shell that is substantially rigid so that the part maintains it shape. The first part holds the product to be packaged, which in the Figures is shown as a confectionery egg. Main surfaces of the first part are shaped so as to substantially conform to the shape of the confectionery egg. Consequently an open mouth to the part is provided. The egg is accessible through the open mouth. A flange is formed about the perimeter of the open mouth. The flange extends away from the main surfaces and continuously about the perimeter of the mouth and extends a substantial distance therefrom in order to provide a surface against which a second part. The confectionery packaging forms a sealed enclosure about the egg by sealing a second part to the flange. To open the packaging, the film is separated from the first part, for instance by peeling back the film. There is therefore provided a packaging which provides an improved protection to the egg and to which graphics can be more reliably applied and reproduced. The preformed part also provides a convenient holder for the egg to allow the user to consume the egg without having to touch the egg itself.
