Tissue Carton with Convex Corner Edges for Product Differentiation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tissue carton shapes, such as cubes and upright designs, are not well-suited for alternative shapes that can differentiate products while maintaining effective dispensing of tissue stacks, often resulting in reduced sheet capacity and dispensing issues, which can impact perceived quality.
Innovation Solution
A novel carton shape featuring at least one corner edge with a convex cross-sectional shape, allowing for distinctive appearance and enhanced dispensing capabilities, achieved through specific crease lines that form a convex edge wall, enabling better handling and grasping while maintaining or improving dispensing efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional cubic or upright carton shapes are used, then manufacturing and stacking are simplified, but product differentiation is limited and dispensing performance is suboptimal
Solution Approach 1:
The patent applies curvature by forming at least one corner edge of the carton with a convex cross-sectional shape, deviating from conventional sharp cubic edges. This curved edge design provides distinctive appearance for product differentiation while maintaining compatibility with standard tissue stack dimensions and dispensing mechanisms, thus resolving the contradiction between manufacturing simplicity and product differentiation capability
2Adaptability or versatility
If alternatively shaped dispensers are used to achieve product differentiation, then distinctive appearance is improved, but sheet capacity is reduced and dispensing problems increase
Solution Approach 1:
The patent applies local quality by implementing convex cross-sectional shaping only at specific corner edges of the carton rather than throughout the entire structure. This localized curvature provides distinctive appearance for product differentiation while the majority of the carton maintains conventional geometry that supports optimal tissue stack capacity and reliable dispensing performance, thus resolving the contradiction between product differentiation and dispensing reliability
3Adaptability or versatility
If convex cross-sectional edge walls are added to create distinctive appearance, then product differentiation is enhanced, but structural complexity increases
Solution Approach 1:
The patent applies curvature through convex cross-sectional edge walls at corner edges, creating distinctive appearance while the overall carton structure remains relatively simple. The convex edge can be formed through straightforward blank design and folding processes, avoiding excessive structural complexity while achieving the desired differentiation effect

AI summary
The present disclosure provides a novel blank for producing cartons, particularly cartons useful for storing and dispensing sheets of tissue, having a novel shape. The cartons have at least one corner edge that is partially formed from an edge wall having a convex cross-sectional shape. In certain instances the carton has four corners and each of the edges is at least partially formed from an edge wall having a convex cross-sectional shape. By providing a carton having one or more convex shaped corner edges not only is a disinvite carton created, but the additional wall forming the convex edge may be provided with graphics that differ from the other carton walls to further enhance the cartons distinctive appearance.
