Smokable rods of cigarettes are manufactured using wrapping materials that incorporate at least one fibrous material (e.g., flax fibers, hardwood pulp fibers and/or softwood pulp fibers) at least one filler material (e.g., calcium carbonate in particulate form). The wrapping materials possess multi-layer coatings. The wrapping materials possess coatings in the form of series of spaced apart bands, each band possessing a series of layers. At least one of the coating layers can have a filler material dispersed or suspended within a film-forming material of that layer.

Wrapping materials for smoking articles

Smokable rods of cigarettes are manufactured using wrapping materials that incorporate at least one fibrous material (e.g., flax fibers, hardwood pulp fibers and/or softwood pulp fibers) at least one filler material (e.g., calcium carbonate in particulate form). The wrapping materials possess multi-layer coatings. The wrapping materials possess coatings in the form of series of spaced apart bands, each band possessing a series of layers. At least one of the coating layers can have a filler material dispersed or suspended within a film-forming material of that layer. For a representative wrapping material, a pattern of applied to the wire side major surface of the wrapping material substrate as a plurality of layers, and at least one of the layers includes ethylcellulose and calcium carbonate. For that layer, the calcium carbonate is present in an amount greater than the ethylcellulose, on a weight basis. The ethylcellulose and calcium carbonate typically are applied as part of a non-aqueous formulation incorporating iso-propyl acetate, triacetin and lecithin.

A flask-shaped package or container for packaging smoking articles, such as cigarettes, has a generally parallelepiped shape with slightly curved front and back body panels. The container comprises a body and a lid integrally molded in one-piece of a plastic material with an open bottom having an internal peripheral shoulder and a base made of a separate plastic/metal foil laminate that is bonded to the shoulder by induction heating a heat-activated adhesive covering the metal foil of the base. The body has a central internal front-to-back stiffening rib and an access opening in its top and front panels with a surrounding ledge to which is adhesively bonded a removable foil closure. After the access opening is closed with the foil closure, cigarettes are inserted into the container body through the open bottom thereof. A protective paperboard liner that prevents adherence between the heat-activated adhesive and the cigarettes is inserted into the open bottom and supported by the central rib and the cigarettes. The base laminate is then inserted into the open bottom and bears on the shoulder so that when the adhesive is activated by induction heating, the base bonds to the shoulder and seals the container. An adhesive-backed label wrap with brand specific indicia is applied to the outer surfaces of the container.

A sealing film and a method of sealing the film to glass is disclosed. The film comprises a layer of ethylene vinyl alcohol (EVOH) or a laminate comprising an outermost ethylene vinyl alcohol (EVOH) layer for adhering to a glass surface, particularly the rim of a glass container, using heat and pressure. The laminate may include in addition to the EVOH layer an adhesive layer, polymeric layer, optional adhesive layer and stock layer. The film has excellent adhesive properties, is food safe and is suitable as a sealing material.

A beauty coil that is in the form of a rod which is comprised of a mass of elongated fibers which run the length of the rod. The fibers are held in a compressed state by an outer sheathing having a pair of longitudinal slits at one end of the rod to form a tab to permit easy removal of the sheath which allows the fiber mass to expand or blossom prior to use.

A method of and an apparatus for cooling or quenching a tube extruded from a water soluble polymer includes a plurality of cooling rings with bores through which the extruded tube passes. A gaseous cooling medium, such as compressed air, is supplied to each cooling ring and is directed immediately downstream of the bore thereof to impinge upon and cool the tubing passing therethrough. The cooling medium is supplied annularly so as to maintain the just-extruded tubing concentric and keep it centered in the bore.

A degradable smoking article comprises a tobacco rod and a filter component made of a gathered web of moisture disintegrative sheet material wrapped with a moisture disintegrative plug wrap bonded along a longitudinal seam with a water soluble adhesive. A moisture disintegrative tipping paper coated on one side with a water soluble adhesive secures the tobacco, rod and filter component together. The combination of moisture and other natural elements such as sunlight, mechanical abrasion, etc., dissociates the components of the smoking article over a relatively short period of time. Other embodiments of the filter component include a hollow degradable tube and a monolithic extruded starch filter rod.

Degradable smoking article

A smoking article having a controlled yield of wet particulate matter and a method of making a smoking article with predetermined total and per puff yields of wet particulate matter. The smoking article has a tobacco rod connected to an air ventilated compound filter having two abutted filter segments, a rod end segment with a passage therethrough and a mouth end segment. The pressure drop of the abutment interface between the segments is selected to be in a range of from about 10 mm to about 100 mm water gauge. The total pressure drop of the filter including the interface and the amount of air dilution can be selected to provide a smoking article with a level per puff yield or a decreasing per puff yield.

Controlled delivery smoking article and method

A cigarette smoking article includes a tobacco rod and a dual filter comprising a tobacco rod end segment made of cellulose acetate tow and a mouth end segment made of a gathered, perforated polymeric film blended with a whitener to produce a substantially non-staining mouth end surface. The polymeric film may also comprise a coextruded flavor film with a flavor carrier layer disposed between a pair of barrier layers for releasing a flavorant into the mainstream smoke during smoking of the cigarette. Transparent wraps may be used to construct the cigarette from the component parts so that the filtration surfaces of the filter rod are visible through the wraps.

Smoking article filter

A flavor burst structure and a method of dispersing a flavorant are disclosed. The flavor burst structure comprises a multilayer film with a flavor carrier layer disposed between barrier layers. The flavor carrier layer comprises a polymeric material blended with a flavorant that is not compatible or is partially incompatible with the polymeric material so that the flavorant desorbs from the carrier layer when one of the barrier layers is removed from the carrier layer. Several package applications are disclosed, including a cigarette package, package tear tapes and the like.
