Display Case Blank with Offset Seam and Tear-Away Window
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing half slotted container designs for corrugated cardboard containers do not efficiently form a display case with a display window, lacking a practical method to create a rectangular tube structure with a visible window.
Innovation Solution
A folded blank comprising interconnected panels with a tear-away section and manufacturer's joint strips is used to form a display case, where the tear-away section separates to create a display window by pivoting the panels, allowing for the formation of a rectangular tube structure with a visible window.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional half slotted container design is used, then the container can be formed from a simple blank, but it cannot efficiently form a display case with a display window and rectangular tube structure
Solution Approach 1:
The blank is segmented into multiple functional sections including a display window section, a rectangular tube section, and a body section. The display window section includes a first panel and second panel that can be folded to form the window, while the rectangular tube section includes multiple panels that form the tube structure. This segmentation allows the single blank to efficiently form both display case and rectangular tube structures.
Solution Approach 2:
The blank incorporates multi-dimensional folding capabilities with fold lines arranged in different orientations. The first fold line, second fold line, third fold line, and fourth fold line create three-dimensional structures from a two-dimensional blank, enabling the formation of both the display window plane and the rectangular tube volume from a single flat blank.
2Stability of the object's composition
If manufacturer's joint strips are applied to connect panels, then the panels can be adhered together to form the rectangular tube, but the joint location may interfere with display window visibility
Solution Approach 1:
The manufacturer's joint strips are asymmetrically positioned on the panels. The first manufacturer's joint strip is applied to the first panel at a location that does not interfere with the display window visibility, while the second manufacturer's joint strip is applied to the second panel. This asymmetric placement ensures both panel connection stability and optimal display window visibility.
Solution Approach 2:
Different regions of the panels are assigned different functions: some regions are designated for manufacturing joints while others are reserved for the display window. The first manufacturer's joint strip is located in a region that will not be visible through the display window, ensuring that the adhesive application does not compromise the aesthetic quality or visibility of the final display case.

AI summary
A folded blank for forming a display case and a display case formed from the folded blank. The folded blank comprises a one-piece blank including a first panel, a second panel, a third panel and a fourth panel connected in series at respective first, second and third vertical fold lines. The first panel is folded about the first vertical fold line and is engaged on a first portion of the second panel at a first manufacturer's joint strip. The fourth panel is folded about the third fold line and is engaged on the first panel at a second manufacturer's joint strip. The first portion forms a tear-away section defined by at least one separation line on the second panel. The first manufacturer's joint strip retains the tear-away section in engagement with the first panel during erection of the folded blank to form the display case having a display window.
