Smoking device incorporating a breakable capsule, breakable capsule and process for manufacturing said capsule

摘要

A smoking device includes a recipient or able to receive burning products, preferably tobacco, and a filter element connected to the recipient, wherein the filter includes at least one breakable capsule, the capsule having a initial crush strength from 0.5 to 2.5 kp, and keeping a crush strength from 0.5 to 2.5 kp and a deformation of less than two third of its diameter prior to rupture after having been submitted to a smoking test. The invention is also relating to the capsule suitable for being incorporated in a smoking device, and to the process of manufacture of the capsule.
