Confectionary Wrapper With Integrated Adhesive Seal And Tear Strip
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing confectionary wrappers, such as those for pralines, face challenges in reducing production costs, improving product preservation, simplifying opening, and maintaining an attractive aesthetic appearance that identifies the product, while ensuring hermetic sealing and ease of access.
Innovation Solution
A wrapper design featuring a folded wrapping sheet with a sealing line, an internal tear strip, and an adhesive label that facilitates controlled opening and hermetic closure, allowing the wrapper to be easily torn into two half-shells for product access, while maintaining a recognizable aesthetic appearance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a hermetically sealed wrapper with two wrapping sheets coupled together is used, then product preservation is improved, but device complexity and production cost increase
Solution Approach 1:
The invention extracts the sealing function from a complex two-sheet coupled structure and concentrates it into a single wrapping sheet with an integrated sealing line. The sealing line is formed by folding the sheet back on itself, creating hermetic sealing without requiring multiple separate sheets to be coupled together, thus simplifying the overall wrapper structure while maintaining preservation effectiveness.
Solution Approach 2:
The invention merges the sealing function with the wrapping sheet itself by creating a sealing line through folding. Instead of using separate sealing components or multiple coupled sheets, the sealing capability is integrated directly into the single wrapping sheet structure, reducing complexity while ensuring hermetic sealing for product preservation.

Solution Approach 1:
The invention extracts the sealing function from a complex two-sheet coupled structure and concentrates it into a single wrapping sheet with an integrated sealing line. The sealing line is formed by folding the sheet back on itself, creating hermetic sealing without requiring multiple separate sheets to be coupled together, thus simplifying the overall wrapper structure while maintaining preservation effectiveness.
Solution Approach 2:
The invention uses a single disposable wrapping sheet with an integrated sealing line instead of multiple coupled sheets. This single-use design simplifies manufacturing and reduces material costs while still providing effective hermetic sealing for product preservation throughout the product's shelf life.
3Ease of operation
If internal tear bands and cuts are applied for easy opening, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The invention merges the opening function with the sealing line structure itself by creating a tear line through folding. Instead of adding separate internal tear bands or cuts, the opening capability is integrated into the sealing line through the folded structure, allowing consumers to easily open the wrapper by tearing along the folded edge while maintaining a simple overall design.
Solution Approach 2:
The sealing line serves multiple functions: it provides hermetic sealing when folded and closed, and it creates a built-in tear line for easy opening. This multi-functional design eliminates the need for separate opening mechanisms, simplifying the wrapper structure while improving ease of operation for consumers.
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 solution provides a cost-effective, easy-to-open wrapper that maintains product preservation and aesthetic appeal, ensuring hermetic sealing and convenient access to the product, with the adhesive label integrated for both sealing and opening functionality.
Implementation Method 1
an adhesive label (16), which is applied directly on the cut (12) and which is designed to ensure hermetic closing of the wrapper

AI summary
Described herein is a wrapper (1) for food products, in particular confectionary products, comprising - a wrapping sheet shaped so as to define a curved portion (2) within which a product is housed; - a tear strip (6) applied on an inner side of said sheet, and - an adhesive label (16) applied on the outer side of said curved portion (2) and on one end of said tear strip (6). The adhesive label (16) provides hermetic closing of the wrapper which is provided with a cut (12) at said one end of the tear strip (6) and at the same time comes to constitute, together with the tear strip (6) the means for opening the wrapper.
