A filter material is described for manufacturing a nicotine delivery product, wherein the filter material is hydroentangled and contains at least 50% and at most 100% cellulose fibers, each with respect to the mass of the filter material, wherein the filter material has a basis weight of at least 25 g/m.sup.2 and at most 60 g/m.sup.2, and wherein the filter material has a structure that is characterized in that it provides the filter material with a transparency that, measured in accordance with DIN 53147:1993-01, is at least 45% and at most 70%. Furthermore, a segment comprising a filter material for a nicotine delivery product, a smoking article which comprises such a segment, an oral nicotine delivery product, and a process for the manufacture of the filter material are described.

A backing with corrugations on a first surface. The corrugations are parallel and each has an airspace along an entire longitudinal length. A second surface of the backing includes perforations or scores oriented perpendicularly or parallel to the corrugations. The corrugations or scores are fold lines or frangible tear lines. The airspaces may also include a filter material. The second surface of the backing may be adhered to a corner of a rolling paper on the surface but opposite edge as a gum strip. The corrugations are parallel to the gum strip.

A smoking article comprises a rod of smokeable material such as tobacco and a tubular support in which the rod is slidably received. The tubular support is formed from a blank of sheet material that is wound in a spiral. Machinery for making the spiral blank is described.

A smoking device includes a recipient or able to receive burning products, preferably tobacco, and a filter element connected to the recipient, wherein the filter includes at least one breakable capsule, the capsule having a initial crush strength from 0.5 to 2.5 kp, and keeping a crush strength from 0.5 to 2.5 kp and a deformation of less than two third of its diameter prior to rupture after having been submitted to a smoking test. The invention is also relating to the capsule suitable for being incorporated in a smoking device, and to the process of manufacture of the capsule.

Shown is a hydroentangled nonwoven for manufacturing a segment for a smoking article, wherein the hydroentangled nonwoven is web-shaped and contains at least 50% and at most 100% cellulose fibers, each with respect to the mass of the hydroentangled nonwoven, wherein the hydroentangled nonwoven has a basis weight of at least 15 g/m.sup.2 and at most 60 g/m.sup.2, wherein the hydroentangled nonwoven has a machine direction and a cross direction orthogonal thereto and lying in the plane of the web of the hydroentangled nonwoven, and wherein the hydroentangled nonwoven has a characteristic plastic deformability in the cross direction which is characterized in that in a tensile test in the cross direction in accordance with ISO 1924-2:2008, the nonlinear portion of the deformation energy absorbed by the hydroentangled nonwoven up to half the elongation at break is at least 10% and at most 50% of the total deformation energy absorbed by the hydroentangled nonwoven up to half the elongation at break.

An insert system for use with a smokable (e.g., such as a pre-rolled or empty cone) including an internal partition that extends from the insert system's first end to an intermediate location between the insert system's first and its second end. A flavor releasing mechanism (e.g., a flavor ball) is located within the insert system between the intermediate location and the system's second end. Accordingly, the internal partition obstructs the flavor releasing mechanism from passing through the system's first end. The system's second end includes an obstructor (e.g., a perforated cap) thereby obstructing the flavor releasing mechanism from passing through the system's second end. The insert system may then be coupled with a smokable item to serve as the item's mouthpiece.

A device that is in combination with a cigarette filter allowing it to become magnetic, to allow proper retrieval of cigarette filters that are improperly disposed of for simpler and incredible improvements to the time and in which they are obtained. A wide variety of materials and combinations may be used in minimal amounts to allow people to obtain many cigarettes in one motion. A new type of cigarette filter allowing improved clean up procedures be done in a very improved manner. Areas with high traffic, private and public gutters littered often and areas that accumulate large amounts of filters may be quickly remedied often and efficiently in short periods of time.

A cooling cigarette filter and a cigarette are disclosed. The cooling cigarette filter comprises a cooling section (2). The cooling section (2) comprises a cooling stick (201) formed from paper (5). The cooling stick (201) has one or more holes (202) communicating two ends of the cooling stick. And the surface of the paper (5) is coated with a cooling material. The cooling cigarette filter has the advantages of ensuring the amount of smoke and lowering the temperature of the smoke entering the mouth. Through the combination design of the structure of the cooling stick and the type and amount of the cooling material, the smoke can flow out of a smoke generation section rapidly and smoothly And the temperature of the high-temperature smoke before entering the mouth can be significantly lowered, thereby improving the comfort and satisfaction of smoking.

The present disclosure relates to a woven fabric filter including a flavored sheet and a smoking article including the same, and more particularly, to a woven fabric filter including a flavored sheet fiber that is a fiber obtained by cutting a flavored sheet and that includes a cellulose-based polymer, a plasticizer, and a flavoring material, and to a smoking article including the same.

The invention relates to a cardboard filter (1) for cigarettes, formed by folding, winding and gluing a cardboard strip (2). According to the invention, the cardboard strip (2) is folded to form a central portion (21) having a series of lobes (3, 4, 5, 6, 7) angularly equally distributed around a central axis (22) of the filter (2) and a peripheral portion (23) surrounding the central portion (21), the lobes (3, 4, 5, 6, 7) and the peripheral portion (23) delimiting gas passage channels (24) around the central axis (22).
