METHOD OF MANUFACTURING SMOKING PRODUCTS WITH MOUTHPIECE CAVITIES Russian patent published in 2021 - IPC A24C5/47 

FIELD: smoking products manufacturing.

SUBSTANCE: invention relates to a method for manufacturing smoking products, which includes the stages of obtaining a continuous structure from the first filter elements, the second filter segments and tubular elements, with a tubular element having a length of at least 4 mm being provided between each pair of consecutive first filter elements, while a second filter segment is provided between each first filter element and each tubular element, and each second filter segment contains one or more destructible capsules, each of which contains an outer shell and an inner core containing an additive, wrapping a continuous structure of the first filter elements, second filter segments and tubular elements with a continuous fitzella sheet to obtain a wrapped filter structure, the fitzella having a surface density of less than 90 g/m², by cutting the wrapped filter structure in an intermediate position along each first filter element to obtain multiple filter rods, each filter rod contains two first filter segments, a tubular element located between the first filter segments, and a second filter segment located between each first filter segment and the tubular element, placing the tobacco rod axially aligned and adjacent to each first filter segment of the filter rod, wrapping the filter rod and part of each tobacco rod with a rim wrap, and cutting the rim wrap and filter rod in an intermediate position along the tubular element to produce a variety of smoking products, moreover, each smoking article contains a tobacco rod connected to a filter, while each filter contains a first filter segment located after the tobacco rod, a second filter segment located after the first filter segment, and a hollow tubular segment located between the second filter segment and the mouthpiece end of the filter, and the hollow tubular segment forms a cavity at the mouthpiece end of the filter.

EFFECT: technical result is to provide resistance to deformation and destruction of the mouthpiece cavities during the manufacture and subsequent use of the smoking product.
