Interleaved paper towel stacks with cold seal adhesives

Overview

The proposed solution addresses common issues with conventional top-loaded interleaved paper towel dispensers by integrating cold seal adhesives to connect separate consumable stacks. This ensures that when one stack is fully used, the first sheet of the next stack automatically presents itself without requiring user intervention. Additionally, a simple linkage mechanism is introduced to prevent overloading by temporarily reducing the internal volume during loading and restoring it afterward.

Technical specifications

Key features:

• Cold seal adhesives: Utilized to bond the top and bottom of towel packs, ensuring seamless transition between stacks. These adhesives are skin-safe and compatible with paper-based products.
• Linkage mechanism: A mechanical solution designed to manage dispenser capacity by adjusting internal volume during loading, thus preventing multiple sheets from being dispensed simultaneously.

Benefits:

• Eliminates manual intervention when transitioning between towel stacks
• Prevents dispensing issues due to overloading
• Uses safe and reliable adhesive technology compatible with existing materials

Technology readiness level

Currently, the solution is at Technology Readiness Level 4, indicating that the concept has been validated in a laboratory environment with further development required for commercial application. The next steps involve identifying suitable cold seal adhesives and designing the linkage mechanism using rapid prototyping techniques such as 3D printing and laser cutting.
