Abstract: Smoking article additive-containing member An additive-containing member having first and second regions, the second region comprising a predetermined region having a reduced strength limit relative to the first region so that the predetermined region is caused to break when pressure is applied to the additive-containing member, thereby to release additive, wherein the predetermined region is at a seal between two parts of the additive-containing member.

Abstract: A filter (11) for a smoking article (10) comprises a first flow path (13) through the filter, a second flow path (14) through the filter, the second flow path being disposed around the first flow path, and a selector (16) for allowing flow selectively through the first and second flow paths.

Abstract: An apparatus is provided to heat smokeable material (3) to volatilise at least one component of the smokeable material, wherein the apparatus comprises a chemical heat source (2); and an actuating mechanism (6), and wherein the actuating mechanism, upon actuation, activates the heat source which heats the smokeable material. A method of heating a smokeable material to volatilise components of the smokeable material for inhalation is also provided, and use of a chemical heat source to volatilise components of the smokeable material for inhalation.

Abstract: Various delivery devices and methods are disclosed, including a delivery device (200) for delivering a dose substance (110) in powdered form to an eye. The device can include a pocket (100A, 100B, 100C) for holding dose substance and a propulsion system (202, 204, 908, 1004, 1006) for propelling a dose consisting of a predetermined volume of said dose substance from said pocket towards said eye, wherein one or both of said pocket and said propulsion system are configured to inhibit propulsion of particles having a size greater than a predetermined threshold to said eye.
