Therefore, the product disclosed in this application which is a cigarillo with a wrapping paper containing recycled tobacco material may also be referred to as a cigarette.

The term "downstream" is used to describe the relative position of the components of the disclosed cigarillo with respect to the direction in which smoke is drawn through the cigarillo in use. The terms "lighting end" and "mouth end" are also used accordingly, as smoke is drawn from the lighting end of the cigarillo to the mouth end.

The term "length" refers to the longitudinal dimension of the cigarillo. The length of the disclosed cigarillos ranges from about 80 mm to about 90 mm. More preferably, the length of the cigarillo is 81-85 mm or 82-84 mm, and in a preferred embodiment, the length of the cigarillo is about 83 mm. The length of the rod of smokable material ranges from about 50 mm to about 60 mm. More preferably, the length of the rod of smokable material is 54-58 mm or 55-57 mm, and in a preferred embodiment the length of the rod of smokable material is about 56 mm. The length of the filter plug ranges from about 25 mm to about 29 mm. More preferably, the length of the filter plug is between 26 and 28 mm, and in a preferred embodiment, the length of the filter plug is about 27 mm.

The tipping paper extends a distance ranging from about 30 mm to about 34 mm from the mouth end of the cigarillo. More preferably, the tipping paper extends a distance of 31-33 mm, and in a preferred embodiment, the tipping paper extends a distance of about 32 mm.

The term "circumference" refers to the circular cross-section of a cigarillo, the dimension around the edge of the circular cross-section extending in a direction perpendicular to the length dimension. The circumference of a cigarillo ranges from about 16 mm to about 18 mm. More preferably, the circumference of the cigarillo ranges from about 16.5 mm to about 17.5 mm, and in a preferred embodiment, the circumference of the cigarillo is about 17 mm.

The term "diameter" refers to the lateral dimension of the cigarillo perpendicular to the length. Preferably, the diameter of the cigarillo ranges from about 5.0 mm to about 5.8 mm. More preferably, the cigarillo has a diameter of 5.1-5.7, 5.2-5.6, or 5.3-5.5 mm, and in a preferred embodiment, the cigarillo has a diameter of about 5.4 mm. It is.

Cigarillo Construction The disclosed cigarillo includes a rod of smokable material surrounded by wrapping paper and a filter adjacent the rod of smokable material.

Cigarillos generally have a diameter of about 6-9 mm, usually about 8 mm, but the disclosed cigarillos have a circumference of 16-18 mm, preferably 17 mm, and a diameter of 5-5.7 mm, preferably about 5 mm. .4mm.

Although cigarillos typically do not have filters, the disclosed cigarillo has a filter at the end of the mouth to filter smoke drawn in by the user during use. Chip paper surrounds the filter. Preferably, tipping paper also surrounds a portion of the rod of smokable material, thereby connecting the filter to the rod of smokable material.

The tipping paper is preferably vented to provide filter ventilation at a level of about or at least 40%, such as about or at least 60%. For example, the tipping paper may be vented to a level of about or at least 40, 41, 42, 44, or 46%, or about or at least 59, 60, 61, 62, or 64%, such as about 40-61%. Filter ventilation can be provided at levels such as %.

The disclosed cigarillo includes a wrapping paper that includes recycled tobacco material. The wrapping paper is preferably single layer.

Cigarillo wrapping paper is typically non-porous. However, the porosity of the disclosed cigarillos is between 3 and 65 Coresta units.

The terms "filter ventilation" and "wrapper porosity" and similar terms are conventional terms in the art and will be familiar to those skilled in the art.

This particular level of porosity of wrapping paper between 3 and 65 Coresta units has been found to offer many advantages in cigarillos with circumferences of 16 to 18 mm.

For example, cigarillos with a circumference of 16-18 mm have been found to have a limited burning period. It has been found that wrapping paper with a porosity of 3 to 65 Coresta units provides a cigarillo that burns more slowly between puffs than a corresponding cigarillo having a wrapping paper with a higher porosity.

A filter ventilation level of at least 40%, such as about 40-61%, about 40-46%, or about 60-61%, also provides a consumer-acceptable opening pressure drop across the product. The combination of paper wrapper porosity and filter ventilation has also been found to have particular benefits for flavor delivery in embodiments where the filter includes flavor.

For example, a level of filter ventilation of about 40-46% has been found to be particularly effective for flavor delivery in embodiments where the filter includes about 2 mg of menthol flavor. Such embodiments typically have an opening pressure drop across the product of about 140-160 mmWG.

Similarly, a level of filter ventilation of about 60-61% has been found to be particularly effective for flavor delivery in embodiments where the filter includes about 4 mg of menthol flavor. Such embodiments typically have an opening pressure drop across the product of about 125-130 mm WG.
