Sealing Sheet With Foldable Layer For Expanded Labeling Space
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing sealing sheets used for pill containers often lack sufficient space on the upper surface to print all required information, making it difficult to provide detailed labeling for each container.
Innovation Solution
An additional foldable layer is integrated onto the sealing sheet, allowing for extra information to be printed on both sides by folding it up, which can be attached to each pill container, enabling more space for labeling without compromising the sealing functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If information is printed only on the upper surface of the top layer of the container-defining sheet, then the labeling is simple and clear, but there is insufficient space to print all required information
Solution Approach 1:
The patent applies dimensionality change by adding a third dimension through a foldable additional layer. Instead of only printing on the two-dimensional upper surface of the top layer, the invention introduces a foldable layer that can be folded upward to provide additional printing surfaces (front, back, and inner surfaces), effectively expanding the information capacity from 2D to 3D space.
Solution Approach 2:
The additional layer is nested within the sealing sheet structure, positioned between the top layer and bottom layer when flat, and can be folded outward to provide additional information space. This nested configuration allows the sealing sheet to contain multiple information layers without increasing the overall footprint when not in use.
2Loss of information
If an additional foldable layer is added to increase information space, then more information can be printed, but the structure becomes more complex
Solution Approach 1:
The additional layer is merged with the sealing sheet structure through adhesive bonding to the top layer, creating an integrated multi-layer assembly. The tearing lines are also merged across layers to ensure synchronized separation, combining multiple functions (sealing, information display, and easy separation) into a unified structure.
Solution Approach 2:
The sealing sheet is segmented into distinct functional layers (top layer, additional foldable layer, bottom layer) with tearing lines positioned to enable controlled separation. This segmentation allows each layer to serve its specific function while maintaining overall structural integrity during use.
3Ease of operation
If the sealing sheet is made with multiple layers and tearing lines, then individual containers can be easily separated, but the manufacturing process becomes more difficult
Solution Approach 1:
The additional layer is pre-positioned and adhered to the top layer during manufacturing, with tearing lines pre-configured to align with the container flanges. This preliminary arrangement of layers and tearing lines simplifies the assembly process by establishing the multi-layer structure before final sealing, making the manufacturing process more systematic and manageable.

AI summary
A sealing sheet for closing a container-defining sheet having a top surface comprising a given number of spaced apart cavities embossed therein, each of the cavities being upwardly opened and defining a container surrounded by a flange. The sealing sheet includes a top layer having a lower surface covered with pressure sensitive adhesive glue, and a bottom layer having an upper surface detachably fixed to the lower surface of the top layer by pressure sensitive adhesive glue. The bottom layer being peelable from the lower surface of the top layer to allow fixation of the sealing sheet onto the top surface of the container-defining sheet in order to close the containers defined in the same. The sealing sheet also includes an additional layer that is tearable into additional elements that are foldably attached on top of each of the containers and on which additional information may be printed.
