Oblong Tissue Dispenser With Inverted Arch Stack for Reliable Dispensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumer product dispensers, such as facial tissue cartons, lack differentiation from traditional rectangular shapes, leading to dispensing issues and perception of poor quality when alternative shapes are used, which can hinder premium product positioning.
Innovation Solution
Forming a sheet-material dispenser into an oblong shape and loading an oblong, inverted arch-shaped folded stack of sheets with the fold axis aligned with the transverse axis of the dispenser, allowing for reliable dispensing characteristics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If an alternatively shaped dispenser is used to differentiate from traditional rectangular shapes, then product differentiation is improved, but dispensing reliability deteriorates due to sheet tears, multiple dispensing, and sheet fallback
Solution Approach 1:
The dispenser uses an oblong shape with asymmetric dimensions (length greater than width) to differentiate from traditional rectangular dispensers. The stack is folded into an inverted arch shape that asymmetrically fills the oblong dispenser, with the fold axis aligned with the transverse axis of the dispenser. This asymmetric configuration maintains reliable dispensing while achieving product differentiation.
Solution Approach 2:
The invention changes the geometric parameters of both the dispenser and the stack. The dispenser has length Ld greater than width Wd (Ld > Wd). The stack is folded into an inverted arch shape with specific dimensional relationships that allow it to fit within the oblong dispenser while maintaining proper sheet alignment and dispensing characteristics.
2Shape
If an alternatively shaped dispenser is used, then product differentiation is improved, but the number of sheets that can fit into the dispenser is reduced
Solution Approach 1:
The stack is folded into a three-dimensional inverted arch shape that efficiently utilizes the volume of the oblong dispenser. By folding the flat stack about a transverse fold axis, the invention creates a spatial configuration that maximizes sheet capacity within the constrained oblong geometry, allowing full sheet counts to be accommodated despite the non-traditional shape.
3Reliability
If the traditional upright carton shape is used, then dispensing reliability is maintained, but product differentiation is lost
Solution Approach 1:
Rather than using the traditional square or rectangular dispenser shape, the invention employs an oblong shape with asymmetric dimensions. The stack is correspondingly folded into an inverted arch that asymmetrically fills the dispenser, maintaining reliable dispensing mechanics while achieving visual differentiation from conventional dispensers.

AI summary
An oblong dispenser having a longitudinal axis and a transverse axis, and wherein a maximum length of the dispenser, Ld, along the longitudinal axis is greater than a maximum width of the dispenser, Wd, along the transverse axis. The dispenser containing a plurality of sheets of a sheet-material formed into a flat stack, and the flat stack folded about a transverse fold axis forming an arch-shaped folded stack having an arched stack top and a stack bottom comprising two legs. The arch-shaped folded stack is placed into the oblong dispenser with the transverse fold axis parallel to the oblong dispenser's transverse axis.
