Abstract: An inhaler article includes a body extending from a mouthpiece end to a distal end with an endpiece element at the distal end. A capsule cavity is defined within the body and extends a cavity length. An air inlet region is between the endpiece element and the capsule cavity. The air inlet region has an air inlet and an air passageway extending from the air inlet to the capsule cavity. The air passageway has an inner diameter less than an inner diameter of the capsule cavity. A porous support element defines a downstream end of the capsule cavity. The porous support element includes one or more apertures extending the length of the porous support element.

Abstract: An inhaler article includes a body (110) extending along a longitudinal axis from a mouthpiece (112) end to a distal end with an endpiece element at the distal end (114). A capsule cavity is defined within the body. An air inlet region is between the endpiece element (120) and the capsule cavity (116). A composite porous support element (140) defines a downstream end of the capsule cavity. The composite porous support element is formed of a first porous material concentrically disposed about a second porous material. The first porous material has a first resistance to draw and the second porous material having a second resistance to draw. The first resistance to draw is different than the second resistance to draw. A mouthpiece air channel (113) extends from the capsule cavity, through the composite porous element to the mouthpiece end.

Abstract: The invention relates to a casting apparatus (100) to cast a sheet of a material containing alkaloids, the casting apparatus including:?a casting box (10) apt to contain a slurry (18) to be cast to form the sheet;?a slurry supply element (5) defining a feeding channel (15) apt to introduce the slurry into the casting box in a supply direction;?path diverting fins (19, 20) positioned within the feeding channel, the path diverting fins being apt to come into contact with the slurry inside the feeding channel;?a movable support (2); and?a casting blade (1) apt to cast the slurry contained in the casting box onto the movable support so as to form the cast sheet. The invention relates also to a method to cast a sheet of a material containing alkaloids.

Abstract: The present invention relates to a casting apparatus (100) for the production of a cast sheet (10) of a material containing alkaloids, the casting apparatus comprising: a casting box (1) adapted to contain a slurry (11) of the material containing alkaloids, the casting box having an aperture (16); a movable support (7); a casting roller (3) positioned at least partly within the casting box adapted to cast the slurry contained in the casting box onto the movable support so as to form the cast sheet; wherein said casting roller faces the movable support forming a gap (I) therebetween, and wherein the movable support is located at least partly above the casting roller. The present invention also relates to a method for the production of a cast sheet of a material containing alkaloids.

Abstract: The invention relates to a casting apparatus (100) to cast a web (1) of a material containing alkaloids, the casting apparatus (100) including: a casting box (10) adapted to contain a slurry (2) to be cast to form the web (1) of a material containing alkaloids, the casting box (10) defining one or more lateral walls (12,14); a slidable lid (80) adapted to slide on the one or more lateral walls (12,14) of the casting box (10); a movable support (20); and a casting blade (70) adapted to cast the slurry (2) contained in the casting box (10) onto the movable support (20) so as to form the cast web (1). The invention also relates to a method to cast a web of a material containing alkaloids.
