Protective Towel Roll Wrapper for Clean Dispensing Outdoors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Disposable absorbent towel rolls are prone to contamination and degradation when exposed to inclement weather or dirty environments, leading to reduced effectiveness and inconvenience in accessing individual towels without proper protection.
Innovation Solution
A flexible, water-resistant wrapper encases the towel roll, providing axial stiffness and protection from water and soil, with a removable cover and a rigid disc for easy access, allowing the roll to be used standalone or as a refill in a protective container.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If disposable wipers are packaged in cardboard boxes with an open hole for dispensing, then towels can be easily accessed by users, but the towels become exposed to water, oil, and dirt leading to contamination and degradation
Solution Approach 1:
The patent applies a flexible plastic wrap film to enclose the towel roll, creating a protective barrier against water, oil, and dirt while maintaining flexibility for dispensing. The film wrap replaces the traditional open cardboard box design, preventing contamination while allowing users to access towels through the flexible packaging structure.
Solution Approach 2:
The flexible plastic wrap film serves as an intermediary barrier between the towel roll and the external environment. This intermediate layer protects the towels from direct contact with harmful substances like water, oil, and dirt, while still permitting the dispensing function to operate effectively.
2Reliability
If cardboard boxes are used to house towel rolls, then the structure provides basic protection, but the boxes become water-soaked and degraded when exposed to the elements, rendering towels useless
Solution Approach 1:
The flexible plastic wrap film provides superior water and oil resistance compared to traditional cardboard boxes. This thin film barrier prevents moisture penetration that would degrade the cardboard structure, maintaining the integrity and usability of the towel roll even when exposed to wet or oily environments.
Solution Approach 2:
The packaging combines the flexible plastic wrap film with the towel roll itself, creating a composite protective structure. The plastic film layer provides water and oil resistance, while the towel roll provides the functional absorbent component, together forming a reliable protected system that resists degradation from environmental exposure.
3Object-affected harmful factors
If a protective container is used to shield towels from contaminants, then towel effectiveness is maintained, but the container adds complexity and requires additional storage space
Solution Approach 1:
The flexible plastic wrap film provides effective protection against contaminants while maintaining a simple, lightweight structure. Unlike rigid protective containers, the flexible film conforms to the towel roll shape, eliminating the need for complex box structures and reducing overall packaging complexity and storage space requirements.
Solution Approach 2:
The flexible plastic wrap film serves multiple functions simultaneously: it protects against water and oil contamination, maintains the structural integrity of the towel roll during dispensing, and provides a flexible packaging solution that adapts to the towel roll shape. This multi-functionality reduces the need for additional protective components, simplifying the overall packaging system.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution ensures the towel roll remains protected and usable, maintaining its shape and functionality, even in less-than-clean environments, and allows for easy access to individual towels without the need for additional storage containers.
Implementation Method 1
a flexible, water resistant, protective wrapper engaging the circumferential surface of the towel roll about its entire circumference. The wrapper is of sufficient strength to restrain significant diametric expansion of the towel roll when the roll is subjected to an axial load
Implementation Method 2
A flexible, water-resistant wrapper encases the towel roll, providing axial stiffness and protection from water and soil

AI summary
A generally cylindrical towel roll product comprises an absorbent towel roll having an upright axis, and a flexible, water resistant, protective wrapper engaging the circumferential surface of the towel roll and of sufficient strength to restrain significant diametric expansion of the towel roll when the roll is subjected to an axial load and to increase axial stiffness of the product. The wrapper includes top and bottom portions that encase the top and bottom surfaces of the roll, respectively, the top wrapper portion having an opening providing axial access to the towel roll and through which individual towels can be drawn axially from the interior of the towel roll. A removable and replaceable soil and water-resistant cover protectively covers the wrapper opening, and a rigid disc may be provided between the top surface of the towel roll and the top portion of the wrapper, the disc extending radially to the periphery of the upper surface of the roll.
