Latest Patents

One of her latest patents is the Multi-ply cigarette filter wrapper. This invention features a filter wrapper paper that includes a paper layer with a first surface and a second surface. The filter wrapper paper demonstrates a first overlap air permeability, which is measured when a perforated tip paper is placed on the first surface, and a second overlap air permeability, measured when the perforated tip paper is placed on the second surface. Notably, the first overlap air permeability is higher than the second overlap air permeability. Another significant patent is the Cigarette with a dual-structure filter. This design incorporates a dual-structure filter that consists of a first filter element and a second filter element arranged downstream of the first. The tobacco rod is positioned upstream of the filter, and a tip paper covers the downstream end portion of the tobacco rod and the circumferential surface of the filter. The tip paper features at least one row of holes formed in a circumferential direction of the filter. Importantly, the air-permeation resistance per unit length of the second filter element is at least twice that of the first filter element, with an air inflow rate from the tip paper being at least 20%.
