Triangular Container Blank for Pizza Slice Packaging
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of suitable containers that can effectively hold triangular-shaped objects, such as individual pizza or pie slices, as existing containers do not accommodate these shapes efficiently.
Innovation Solution
A triangular container blank made from cellulose-based materials, such as fiberboard or paperboard, is designed with specific fold lines and panels that can be assembled to form a container capable of holding triangular objects, featuring hinged connections and corner tabs for secure closure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional containers are used, then they are easy to manufacture and assemble, but they cannot effectively hold triangular-shaped objects
Solution Approach 1:
The container is divided into multiple panels (front panel, rear panel, first side panel, second side panel) that are hingedly connected to form a triangular prism structure. This segmentation allows the container to adapt to triangular-shaped objects while maintaining ease of manufacture through modular assembly from a single blank piece of material.
Solution Approach 2:
The container transitions from a two-dimensional blank piece of material to a three-dimensional triangular prism structure through folding along predetermined fold lines. This dimensional transformation enables the container to hold triangular-shaped objects efficiently while starting from a simple, easy-to-manufacture flat blank.
2Reliability
If a triangular container is designed to fit triangular objects, then it provides secure holding, but it increases device complexity
Solution Approach 1:
Multiple functional elements are merged into a single integrated blank piece of material, including the triangular prism body, hinged connections, corner tabs, and closure mechanisms. This merging reduces device complexity by eliminating the need for separate components while maintaining secure holding capability through the unified structure.
Solution Approach 2:
The container features self-assembling characteristics where the blank automatically forms the triangular prism structure through folding along predetermined lines, and the corner tabs automatically align and secure the panels in place. This self-service mechanism reduces complexity by eliminating the need for complex fastening systems or assembly tools.
3Ease of manufacture
If a single piece blank is used, then manufacturing is simplified, but assembly precision requirements increase
Solution Approach 1:
The blank is pre-marked with predetermined fold lines and pre-formed with corner tabs in specific geometric configurations during manufacturing. This preliminary action ensures that when assembly occurs, the folding and alignment processes follow predetermined paths, reducing the precision requirements during final assembly while maintaining the benefits of single-piece manufacturing.

AI summary
The present invention includes a blank and container formed of cellulose-based materials configured to form a triangular shaped container. The container includes a triangular shaped bottom panel, side walls and a rear wall that define a first triangular volume. The top panel and second side panels generally form a second triangular volume that is slightly larger than the first triangular volume. The second triangular volume is configured to fold over the first triangular volume such that the top panel and second side panels fully enclose the bottom panel and the first side panels. The container is locked by a friction fit between juxtaposed tabs inserted into a slot located between the ends of the intersecting first side panels.
