Title
(EN) FILTER ELEMENT FOR A SMOKING ARTICLE
(FR) ÉLÉMENT FILTRE POUR ARTICLE À FUMER
Abstract
(EN)
A filter for a smoking article comprises at least one plug of filter material surrounded by a plug wrap. The plug of filter material comprises at least two segments being longitudinally aligned and rotatably mounted about a common longitudinal axis, at least one of the segments comprising at least one perforation formed in the plug wrap to allow air intake into the filter in use. A tipping paper surrounds the plug wrap. The tipping paper comprises a first part attached to a first of the two segments of the filter plug and a second part attached to the second segment of the plug wrap and comprising at least one aperture formed therein, the tipping paper parts and filter plug segments are arranged such that the respective aperture and perforation of the tipping paper and the filter plug can be superimposed upon rotation of one of the filter plug segments about its longitudinal axis to vary the filter ventilation: At least one frangible capsule in the plug of filter material is provided, said capsule containing a substance for altering the characteristics of an air stream passing though the filter in use, wherein the at least one frangible capsule and the perforation and aperture in the filter plug and tipping paper are offset from each other longitudinally in the filter.
(FR)
La présente invention concerne un filtre pour un article à fumer comportant au moins un embout de matériau filtre entouré d'un papier pour filtre. L'embout de matériau filtre comporte au moins deux segments alignés longitudinalement et montés en rotation autour d'un axe longitudinal ordinaire, dont au moins un des segments comporte au moins un ajour formé dans le papier pour filtre pour permettre à l'air d'entrer dans le filtre lors de l'utilisation. Un papier d'embout entoure le papier pour filtre. Le papier d'embout comporte une première partie fixée à un premier segment des deux segments de l'embout de filtre et une seconde partie fixée au second segment du papier pour filtre et comportant au moins une ouverture formée en son sein, les parties du papier d'embout et les segments de l'embout de filtre sont agencés de telle sorte que l'ouverture et l'ajour respectifs du papier d'embout et de l'embout de filtre peuvent être superposés à la rotation de l'un des segments de l'embout de filtre sur son axe longitudinal pour varier la ventilation du filtre : au moins une capsule cassable est agencée dans l'embout de matériau filtre, ladite capsule contenant une substance permettant d'altérer les caractéristiques d'un courant d'air traversant le filtre lors de l'utilisation, ladite capsule cassable et l'ajour et l'ouverture dans l'embout de filtre et le papier d'embout étant décalés les uns par rapport aux autres de manière longitudinale dans le filtre.
