SMOKING ARTICLE WITH TACTILE LIQUID RELEASE COMPONENT Russian patent published in 2018 - IPC A24B15/28 

FIELD: smoking accessories.

SUBSTANCE: invention relates to a smoking article comprising a sustained release liquid delivery component that provides a new tactile sensation during compression. Smoking article includes a liquid release component comprising a sustained release liquid delivery material, comprising an inner core of a sustained release liquid delivery material, a closed matrix structure comprising a cross-linked polymer matrix defining a plurality of domains; a liquid composition that is trapped within the domains and is releasable from the closed matrix structure upon compression of the material, and a breakable outer shell enclosing the inner core of the liquid delivery material, wherein the force/displacement curve obtained upon compression of the smoking article at the location of the liquid release component in a force/displacement test comprises a plurality of local minima in the force level over a range of compression of at least 1 mm, wherein each of the local minima corresponds to a reduction in the force level of at least 1 N.

EFFECT: technical result of the invention is to provide an improved liquid delivery material for a smoking article that provides an indication to the consumer that the liquid has been released from the material, provides a new sensation when it is compressed by the consumer and has an improved ability to retain volatile liquid additives during storage and improved resistance to moisture and dampness.
