  • Publication number: 20240081391
    Abstract: A filter part (1, 1?) for use in an aerosol generating article and a method of manufacturing the filter part (1, 1?). The filter part (1, 1?) includes an aerosol permeable core (2) within a sleeve (3) formed integrally therearound. The core (2) is shorter than the integrally formed sleeve (3). The method includes conveying a plurality of aerosol permeable cores (2) along a conveying path at a first speed (S1) and forming a sleeve (3) around each core (2) at a second speed (S2). The second speed (S2) is greater than the first speed (S1) to generate a space between consecutive cores (2) within the sleeve (3).

  • Patent number: 11896048
    Abstract: A filter part (1) for use in an aerosol generating article and a method of manufacturing the filter part (1). The filter part (1) includes an aerosol permeable core (11) surrounded by a sleeve (12). The sleeve (12) is formed of linear, axially oriented fibres and the core (11) is formed of expanded, randomly oriented fibres. The method includes forming two or more strips (2a, 2b) into segments surrounding a conveying path, bringing the segments together into a sleeve former (7) to form the sleeve (12) and introducing loose fibres (52) between the segments upstream of the sleeve former (7) such that they are drawn therein in a random orientation and compressed between the segments as they are brought together to form a filter rod (8) with an aerosol permeable core (11) within the sleeve (12). The filter rod (8) is then cut to form the filter part (1).

  • Patent number: 11278989
    Abstract: A hinge lid container (10) for consumer articles comprises a box (12) and a hinge lid (14) connected to the box along a hinge line and pivotable about the hinge line between a closed position and an open position. The hinge lid comprises a first lid wall (16) and a lid flap (18) depending from the first lid wall along an edge fold line, the lid flap being folded inward towards the inner surface of the first lid wall. The container is at least partially formed from a blank having a thickness (T), the laminar blank defining an edge fold portion of the container connecting the first lid wall and the lid flap. The inner surface of the edge fold portion defines an ablation area (A) having a length in the longitudinal direction of the edge fold portion and a width (W) extending transversely to said length.

  • Publication number: 20210000167
    Abstract: A filter part (1, 1?) for use in an aerosol generating article and a method of manufacturing the filter part (1, 1?). The filter part (1, 1?) includes an aerosol permeable core extrusion (2) surrounded by a sleeve (3) formed of predominantly linear, axially oriented fibres. The method includes forming two or more strips (4a, 4b) into segments surrounding a conveying path, bringing the segments together into a sleeve former (7) to form the sleeve (3) and introducing an aerosol permeable core extrusion (80) between the segments upstream of the sleeve former (7) and bonding the segments together to form a sleeve surrounding the core extrusion (80), thereby forming a filter rod (9). The filter rod (9) is then cut to form the filter part (1, 1?).
