Description

  The present invention relates to a smoking article having variable ventilation characteristics, and more particularly to a filtered cigarette having variable ventilation characteristics.

  Generally, a cigarette with a filter comprises a cylindrical rod of a tobacco cut filter wrapped with wrapping paper and a cylindrical filter that is axially aligned with the wrapped tobacco rod in end-to-end contact relationship. . Traditionally, the packaged tobacco rod and filter are joined by a chip paper strip that surrounds the entire length of the filter and adjacent portions of the packaged tobacco rod. The tip paper may comprise one or more circumferential perforations for ventilating tobacco mainstream smoke generated during combustion of the packaged tobacco rod with the outside air at a location along the filter. Filtered cigarettes with a mechanism for changing the ventilation level obtained when smoking are known, which can change the ratio of tobacco mainstream smoke to the outside air delivered to the consumer's oral cavity.

  For example, U.S. Pat. No. 4,570,649 includes a substantially cylindrical tobacco rod, a substantially cylindrical filter plug, plug wrap paper surrounding the filter plug, and plug wrap paper and tobacco rod. Disclosed is a filter cigarette with variable dilution level, comprising chip paper surrounding the portion. At least one of the plug wrap paper and the chip paper is air impermeable. The plug wrapping paper is divided into a mouth end band, a central band, and a rod end band having a first opening. The mouth end strip and rod end strip are attached to the filter, while the central strip is rotatable about the longitudinal axis of the filter plug. The chip paper is divided into a first strip and a second strip. The first strip of chip paper extends from the mouth end of the filter plug to a portion overlapping the rod end strip of the plug wrapping paper, and is attached only to the central strip of the plug wrapping paper. Around to rotate together. The first band of the chip paper has a second opening that overlaps the rod end band of the plug wrapping paper, and the second opening is a first end of the rod end band by the rotation of the first band. Rotating at various alignment angles relative to the opening results in a change in the dilution level obtained during smoking. A second strip of chip paper extends from the first strip to a position on the tobacco rod and couples the tobacco rod to the filter plug.

U.S. Pat. No. 3,519,000 discloses a ventilated tobacco pipe with an air-to-smoke control valve that includes a valve stem that attaches to a valve body and a valve head. The valve body is rotatable with respect to the valve stem so as to change the degree to which the smoke and outside air from the tobacco in the pipe are mixed in a mixing chamber formed in the valve head. Indicator markers on the outer surface of the valve stem indicate the magnitude of the smoke ratio that occurs at different relative rotational positions of the valve stem and the valve body when used in conjunction with tick marks formed on the outer surface of the valve body. The tick marks are not symmetrical about the longitudinal axis of the tobacco pipe. Rotating the valve head clockwise relative to the valve body closes the smoke inlet and opens the air inlet, which increases the smoke ratio, but rotating the valve head counterclockwise relative to the valve body opens the smoke inlet. Since the air inlet is closed, the smoke ratio is reduced. At the tip of the valve head rotating part, one of the one inlets is completely closed and the other inlet is completely opened.
Filtered cigarettes with other mechanisms for changing the ventilation level when smoking are also known.

  French Patent No. 2273443 comprises a first filter plug adjacent to the cigarette and a mouth filter plug separated from the first filter plug by a cavity having a flexible tubular wall, Cigarettes with variable filter characteristics are disclosed. The mouth side filter plug is rotatable about the longitudinal axis of the filter with respect to the first filter plug and can gradually reduce the cross section of the cavity forming the spiral passage to increase the filter characteristic level. The rotation of the plug relative to the first filter plug does not change the tobacco ventilation level. In order for the user to directly select a filter characteristic at a desired level, a scale with a scale is provided on the outside of the first filter plug, and a position display marker is provided on the outside of the mouth side filter plug.

The invention will now be described, by way of example, with reference to the accompanying drawings, in which:

1 is a perspective view of a cigarette with a filter having variable ventilation characteristics according to a first embodiment of the present invention. It is a perspective view of the tobacco with a filter with which the ventilation characteristic is variable by the 2nd Embodiment of this invention. It is a perspective view of the tobacco with a filter with which the ventilation characteristic is variable by the 3rd Embodiment of this invention. FIG. 4 is a schematic side view of a filtered cigarette with variable ventilation characteristics at a position with high ventilation characteristics according to the embodiment of the present invention shown in FIG. 3. FIG. 4 is a schematic side view of a filtered cigarette with variable ventilation characteristics at low ventilation characteristics according to the embodiment of the present invention shown in FIG. 3.

The filtered cigarettes shown in FIGS. 1 to 5 generally have a plurality of components, which are given the same reference numbers.
Referring to FIG. 1, a filter cigarette 10 with variable ventilation characteristics according to a first embodiment of the present invention is generally made of smokable material attached to one end of an elongated cylindrical mouthpiece 3 aligned in an axial direction. An elongated cylindrical packaging rod 1 is provided.

  The mouthpiece 3 comprises an element (not shown) that is rotatable about the longitudinal axis of the filtered cigarette 10. As will be described in detail below with reference to a filtered cigarette with variable ventilation characteristics according to the third embodiment of the present invention of FIGS. The ventilation characteristics of the cigarette with filter 10 obtained at the time of smoking can be changed. Filtered tobacco 10 also includes a ventilation indicator or gauge 5 that allows the consumer to select the tobacco ventilation characteristics obtained when smoking, i.e. the flavor delivered to the consumer. The ventilation indicator 5 includes a triangular position display marker 7 and a scale 9. The triangular position display marker 7 is arranged outside the rotating element of the mouthpiece 3. However, it should be understood that other configurations in which the scale 9 is located outside the mouthpiece 3 of the rotating element are possible.

  The scale 9 includes a plurality of bars extending in substantially parallel to the longitudinal axis of the filter-equipped tobacco 10 and having different lengths spaced in the circumferential direction. In use, the position of the triangular position indicator marker 7 along the scale 9 indicates the degree of rotation of the rotating element of the mouthpiece 3 with respect to the remainder of the filter cigarette 10, ie the ventilation level obtained when smoking the cigarette 10 with filter. However, the ventilation level is indicated by the longitudinal distance between the triangular position indicator marker 7 and the tip of the scale 9 aligned in the longitudinal direction.

  As described above, the triangular position indicator 7 and the scale 9 are palpable, and the consumer can select the desired ventilation level by touching and / or further viewing. The scale 9 is symmetric around the longitudinal axis of the filtered cigarette 10. In the illustrated embodiment, the center bar of the scale 9 is the shortest and the end bar of the scale is the longest. This indicates that the consumer can obtain the same ventilation level by rotating the rotating element of the mouthpiece 3 and simultaneously the triangular position indicator marker 7 either clockwise or counterclockwise. The consumer rotates the rotating element of the mouthpiece 3 with respect to the rest of the cigarette 10 with the filter so that the triangular position indicator marker 7 is aligned with a specific bar of the scale 9 in the longitudinal direction, thereby providing the desired ventilation. You can select the level.

  In the embodiment shown in FIG. 1, when the triangular position display marker 7 is aligned with the shortest bar of the scale 9, the longitudinal distance between the triangular position display marker 7 and the tip of the scale 9 aligned in the longitudinal direction. Is the maximum and indicates a high ventilation level. When the rotation element of the mouthpiece 3 is rotated so that the triangular position display marker 7 is aligned with one of the longest bars of the scale 9, the position between the triangular position display marker 7 and the tip of the scale 9 aligned in the longitudinal direction is The longitudinal distance of is minimal, indicating a low ventilation level.

  The filtered cigarette according to the invention, in another way, exhibits a ventilation level with a low minimum longitudinal distance between the position indicator marker and the tip of the scale aligned in the longitudinal direction, and is aligned with the position indicator marker in the longitudinal direction. It should be understood that the maximum longitudinal distance between the tip of the scale can include a position indicator and a ventilation indicator with a scale that indicates a high ventilation level.

  In addition, the cigarette with a filter according to the present invention includes a position display marker and a scale in which the position display marker aligned with the center point of the scale indicates a low ventilation level, and the position display marker aligned with the end point of the scale indicates a high ventilation level. It should be understood that a ventilation indicator can be provided.

  The ventilation indicator 5 of the filtered cigarette 20 according to the second embodiment of the invention shown in FIG. 2 is for the most part the same as the filtered cigarette 10 according to the first embodiment of the invention shown in FIG. A triangular position indicator marker 7 and a scale 9 symmetrical about the longitudinal axis of the filtered cigarette 10 having a logo with a V-shaped end adjacent to the position indicator marker.

The filtered cigarette 30 according to the third embodiment of the present invention shown in FIG. 3 has one suitable mechanism for changing the ventilation level obtained when smoking.
The mouthpiece 3 of the cigarette with filter 30 of this embodiment includes a single segment filter 31 that abuts adjacent to the packaged tobacco rod 1.

  The filter segment 31 is 27 mm long and can be composed of a high efficiency cellulose acetate plug surrounded by an air impermeable filter wrapping paper 33 along its entire length. The wrapping paper 33 includes a pair of opposing elongated openings 35 disposed about 15 mm from the mouth end of the filter, each extending about 90 degrees circumferentially around the filter. In FIG. 3, only one of the elongated openings is shown, but in practice only a single elongated opening 35 is required.

  The packaged tobacco rod 1 and the filter segment 31 are connected by a tip paper 37 of a rod end band that is approximately 10 mm long and surrounds a portion of the filter segment 31 and an adjacent portion of the packaged tobacco rod 1. The chip paper 32 of the mouth side end band body can surround the filter segment 31 on the mouth side and have a length of 12 mm. Both strips of rod end 37 and mouth end 32 are secured in place with an adhesive.

  Between the tip paper rod end strip 37 and the mouth end strip 32 is a tip paper sleeve 34 that surrounds the filter and abuts both the rod end strip 37 and the mouth end strip 32. Since the sleeve 34 which is the rotation element of the mouthpiece of the present embodiment is not bonded to the filter wrapping paper, it can freely rotate around the longitudinal axis of the cigarette 30 with the filter. The rod end band body 37 and the mouth side end band body 32 function as stoppers that prevent the sleeve 34 from moving in the axial direction. The sleeve 34 is 12 mm long and includes a pair of opposing elongated openings 39 disposed about 15 mm from the mouth end of the filter, each extending about 90 degrees circumferentially around the filter. it can. In FIG. 3, only one of the elongated openings is shown, but in practice only a single elongated opening 39 is required.

  As shown in FIGS. 4 and 5, the annular position of the sleeve 39 relative to the lower filter wrapper 33 can be changed to change the ventilation level and consequently the air dilution level for mainstream smoke obtained when smoking the cigarette 30 with filter. . This can be realized by selecting the degree of alignment between the opening 35 of the filter wrapping paper and the opening 39 of the sleeve 34.

  FIG. 4 shows the filtered cigarette 30 in the “open” position with a high ventilation level, with the sleeve 34 rotated to a position where the opening 39 is fully aligned with the opening 35 of the lower filter wrapper 33. In this “open” position, the opening 35 of the filter wrapping paper 33 is not covered at all. Thus, when smoking the filtered cigarette 30 in the “open” position, a high level of air dilution for mainstream smoke is obtained.

  FIG. 5 shows the filtered cigarette 30 in a “closed” position with a low ventilation level, with the sleeve 34 rotated to a position where the opening 35 of the filter wrapper 33 is completely covered by the sleeve 34. In this “closed” position, the opening of the air-impermeable filter wrapper 33 is substantially sealed by a sleeve. Thus, when smoking the tobacco 30 in the “closed” position, a low level of air dilution relative to mainstream smoke is obtained.

  In the “open” position, the air dilution level for mainstream smoke is high due to high ventilation levels, but conversely, in the “closed” position, the air dilution level for mainstream smoke is low due to low ventilation levels. Thus, the resulting ventilation characteristics are effectively changed with the rotation of the sleeve.

  The cigarette 30 with a filter can further include a ventilation indicator 5 (not shown) having a position indication marker 7 and a scale 9 similar to those shown in FIGS. 1 and 2, and one of the position indication marker 7 and the scale 9. Is disposed outside the sleeve 34, and the other of the position indicating marker 7 and the scale 9 is disposed on either the tip end rod body 37 of the tip paper or the mouth end end body 32 of the tip paper.

  To form a filtered cigarette 30 with variable ventilation characteristics according to the third embodiment of the present invention, the packaged filter segment 31 and the packaged tobacco rod 1 can be manufactured in a conventional manner. A rod end band 37 and a mouth end band 32 and a sleeve 34 are made using a sheet of pre-perforated chip paper. The chip paper layer needs to be cut to form the mouth end band, the first perforation row 10 mm from one end, and the center band and the rod end band, Includes a second drilling row of 12 mm from the first row. If desired, double length chip paper can be used in conventional manufacturing processes. One or more specially formed guides are incorporated into conventional cigarette making equipment to cut at the chip paper perforation line to ensure adhesion in place of the cigarette. Additional cutting knives can also be incorporated to cut one or more perforation lines. All perforation lines are cut in the same or a separate manufacturing process to ensure that the consumer can use them, i.e. the sleeve can rotate freely and easily around the filter. The filter wrapper and sleeve opening can be made simultaneously using a laser when the filter cigarette is assembled.
