Definitions

  • This invention relates to a smoking device incorporating a breakable capsule, more particularly to a filtered smoking device incorporating such a capsule in its filter element.
  • capsule means a delivery system of a substance, said substance being hereinafter referred to as "the cores which is enclosed into a shell.
  • breakable capsule refers to a capsule as hereabove defined, wherein the shell can be broken by means of a pressure to release the core, more specifically the shell can be ruptured under the pressure imposed by the smoker's fingers when the smoker wants to release the core of the capsule.
  • some smoking devices incorporating a breakable capsules are known (see e.g. WO 03/009711 A ).
  • Us2004/0261807 describes a cigarette comprising a tobacco rod and a filter element connected to the tobacco rod, said filter having a cavity wherein a capsule is disposed.
  • Said capsule comprises an outer gelatin shell, and an inner liquid composition including flavoring agents.
  • the goal of US2004/0261807 is to make it possible for the smoker to break the capsule, during the combustion of the cigarette, to allow the release of the core of the capsule.
  • the gelatin capsule is a good storage capsule, but is sensitive to moisture, and may soften during the smoking time. This softening results in that the gelatin shell loses its breakability, i.e. its ability of being ruptured under the pressure imposed by the smoker's fingers when the smoker wants to release the core of the capsule.
  • the gelatin capsule of the prior art has a very important deformation when placed in smoking moisture conditions, which prevents the smoker from breaking it through a pressure of his/her fingers.
  • the ability to rupture is measured through the crush strength to be exerted to rupture the capsule and through the deformation of the capsule when pressure is applied.
  • the crush strength at a dry state shall not exceed 2.5 kp: a crush strength of more than 2.5 kp appears too high to achieve the expected results.
  • the Applicant has now found that the incorporation of selected hydrocolloids in the outer shell of the capsule, and/or the coating of the outer shell by a moisture barrier layer, results in capsules keeping their ability to rupture within a smoking device even after exposition to the moisture brought in said smoking device by the smoker.
  • the invention relates to a smoking device comprising:
  • the recipient may be the rod of a cigarette, wherein the burning product is tobacco.
  • the initial crush strength Ci of the capsule is measured before smoking, by continuously applying a load vertically onto one particle until rupture using a LLOYD - CHATILLON Digital Force Gauge, Model DFIS 50, having a capacity of 25Kg, a resolution of 0.02 Kg, and an accuracy of +/- 0,15 %.
  • the force gauge is attached to a stand; the capsule is positioned in the middle of a plate that is moved up with a manual thread screw device. Pressure is then applied manually and the gauge records the maximum force applied at the very moment of the rupture of the capsule, (measured in Kg or in Lb). Rupture of the capsule results in the release of the core.
  • the smoking test A is performed on the smoking Machine HEINR BORGWALDT RM 4/cs.
  • the cigarette containing breakable capsule is positioned on the smoking machine in the standard starting position.
  • the adjustable parameters are set up as follows: Puff volume: 35 ml (as defined in internationally standard method for smoking machine) Puff period: 60 seconds Puff duration: 2 seconds Puff sweep time: 1.8 second Exhaust sweep time: 1 second
  • the test is finished when the cigarette is completely smoked or after 7 or 8 puffs.
  • the final crush strength Cf is measure after having completing the smoking test A, following the same measurement procedure as used for the measure of Ci.
