Latest Patents
Mathews' latest patents include the "Reduced Ignition Proclivity Smoking Article Wrapper" and "Method and Smoking Article Wrapper for Reducing Sidestream Smoke." The first invention presents an improved wrapper construction for smoking articles that minimizes the risk of igniting combustible materials accidentally. This innovative wrapper features a specially designed structure that causes a cigarette to extinguish quickly upon contact with various substrates. The Burn Mode Index (BMI) for the wrapper is defined to be between about 1.5 cm-1 and 5.0 cm-1 for a single wrap, while the double-wrapped embodiment has a BMI ranging from about 2.0 cm-1 to about 40 cm-1. The use of burn promoters, such as potassium citrate, is crucial in achieving these results without compromising taste and smoke delivery.
The second patent focuses on a sheet material that significantly reduces sidestream smoke when used as wrappers for smokable articles. This sheet is created by applying an excess amount of alkali metal salts to a cellulosic web, which can include flax fiber. The invention claims that using at least 6% by weight of potassium citrate can lead to a reduction of total particulate matter in sidestream smoke by up to 50%, while maintaining desirable properties.
