Description

  The present invention relates to a cigarette with a filter having a variable ventilation rate.

  Cigarettes with a filter are well known, and generally have a cylindrical rod-shaped portion of cigarettes wrapped with wrapping paper and a cylindrical filter adjacent to the same coaxially. The tobacco rod and filter are typically joined by a tip paper wrap that covers the entire filter and the portion adjacent to the wrapped tobacco rod. It is also well known that chip paper is provided with one or more perforations in part of the filter to introduce air into the smoke generated from the lit tobacco rod. In addition, since the smoke to air ratio increases the cigarette strength, the mixing ratio of air through the perforations is changed so that the user can change the cigarette strength by changing the air to smoke ratio. Means are also provided.

  An example of such a cigarette is disclosed in US Pat. No. 4,570,649. This document discloses a conventional cylindrical tobacco rod-like portion attached to a filter plug. The filter plug is wrapped with plug wrapping material and chip paper, at least one of which is impermeable to air. In this prior art configuration, the plug wrap is divided into three strips, one located at the cigarette mouthpiece, the other at the central strip, and the further strip as a rod. Adjacent to the department. The band on the mouth side and the bar-shaped part are joined to the filter, and the band at the center is rotatable about the long axis of the cigarette. The chip paper is disposed so as to overlap the plug winding material, and consists of two strips. The first belt portion covers from the mouthpiece to the portion on the rod-like portion side of the plug winding material, and comes into contact with the central belt portion of the plug winding material and rotates integrally therewith. The first belt portion of the chip paper has a hole at a position overlapping the belt portion on the rod-shaped portion side of the plug winding material. The strip on the rod-shaped part side of the plug winding material has at least one opening, and the hole can be aligned with the position of the opening of the plug winding material by rotating the first band of the chip paper. It is possible to change the amount of air inhaled during smoking, and thus to change the mixing ratio of smoke from the burning tobacco rod to the outside air to adjust the strength of the tobacco.

  Such cigarettes are popular with consumers, but consumers can change the strength of the cigarette, but how the mixing of air and smoke is regulated, i.e., how much is about smoking cigarettes There is a problem that it is not clear whether the strength of the choice is selected. In order to solve this problem, for example, as disclosed in International Publication No. 2011/116976, a combination of a scale and a cursor is introduced to inform the user of the adjustment amount, and the cursor is placed on either the fixing part or the rotating part of the cigarette. And a scale is provided on the other of the fixed part and the rotating part to indicate the amount of ventilation of the cigarette filter by the relative movement of the cursor and the scale. However, such a configuration does not provide a simple and clear indicator of the strength of the selected cigarette, and the user is still very uncertain about adjusting the cigarette strength. I feel sex.

  According to the present invention, there is provided a cigarette with a filter, which is a rod-shaped portion containing a smoking material, and a mouthpiece attached to the rod-shaped portion, wherein the filter allows the user to change the ventilation rate of the cigarette with filter. A mouthpiece having an element rotatable about the long axis of the cigarette with respect to the other part of the cigarette with filter, a fixing element fixed relative to the rod-shaped part, and a strength indicator; The strength indicator has a first scale provided around the outer periphery of the rotatable element and a second scale provided around the outer periphery of the fixed element, each scale being A filtered cigarette is provided that constitutes a marker formed by a separation line between the rotatable element and the other part of the cigarette and a line intersecting at both ends.

  According to the configuration of the present invention, the user can simply and clearly know which level of cigarette strength has been selected by the rotation of the strength selection member. According to the configuration of the present invention, the user can easily and reliably know the selected strength regardless of the rotation direction of the strength selection member.

  In some examples of the present invention, when the two scales are at a position representing the lowest level of strength, a figure consisting of at least one closed line is formed jointly by the two scales. In addition, when the two scales are at a position showing the lowest level of strength, the two scales may have a symmetrical shape with respect to the separation line. In this way, the user can easily match the two scales when he wants to have the lowest level of strength during smoking. In a preferred embodiment, a polygon having an even number of sides may be formed by the two scales when the two scales are at a position showing the lowest level of strength.

  In addition to or in place of the above, when the two scales are at a position showing the highest level of strength, the two scales may be in contact with each other only at one end of each of the two scales. . This allows the user to know that the amount of tobacco ventilation is minimal and that the tobacco rod cannot rotate any further relative to the fixed element.

  Preferably, one or both scales of the filtered tobacco may be symmetric with respect to the long axis of the tobacco.

  In some embodiments, one or both graduations may be formed by continuous lines. In other embodiments, one or both scales may be formed by discontinuous lines.

Hereinafter, an example of the present invention will be described with reference to the accompanying drawings.
FIG. 1 is a side view showing components in the process of forming tobacco according to the present invention. FIG. 2 is a side view of a tobacco formed in accordance with the present invention. FIG. 3 is a series of end cross-sectional views showing the filter and vent member of the present invention in a position to select different tobacco strengths. In the example of FIGS. 1 to 3, the filter part 3 and the chipping 9 each have only one perforated part 8 and one long hole 13. However, the filter portion and chipping may have a plurality of perforated portions and a plurality of long holes, respectively, and even in this case, no problem occurs in the filter function. FIG. 4 is a diagram showing an example in which the indicator according to the present invention is in a position for selecting different cigarette strengths.

  As shown in FIG. 1, the cigarette 1 with a filter has a tobacco rod-like portion 2 and a filter portion 3. The filter unit 3 is configured such that the user can adjust the air flow rate of the filter in order to adjust the strength of the tobacco flavor. The filter portion 3 is provided with a plug made of a filter material such as acetate, for example, having a plug winding material 4 covering the outer peripheral surface thereof. The filter part 3 is divided into two filter sections 5 and 6 by a cut line 7 formed perpendicularly to the long axis of the tobacco 1 and laterally on the outer periphery. The cut line 7 is formed only halfway through the diameter of the filter plug 4 so as to leave a central connection portion of the filter material between the two areas 5 and 6. This connecting portion preferably acts as a shaft for the relative rotation of the two sections 5, 6 so that the air flow of the filter can be adjusted as described below. At least one perforated portion 8 is formed in the area 6 of the plug wrap 4 on the side of the filter portion 3 that contacts the tobacco rod-like portion 2. Air can be introduced to the core portion of the filter portion 3 through the plug wound material 4 by the perforated portion 8. In order to couple the filter part 3 with the tobacco rod-like part 2, a chip paper 9 is provided so as to wrap the plug wrap 4 and the filter areas 5, 6. The chip paper 9 includes two winding bands 10 and 11 separated by a cut line 12. The first wrapping band 10 is bonded to the filter section 5 on the mouth side of the cigarette 1, exceeds the cut line 7 that divides the filter sections 5, 6, and is in the middle of the second filter section 6 including the perforated portion 8. Is not bonded to the second area 6. The first tip winding band 10 has a long hole 13 formed at a position overlapping the perforated portion 8 of the second filter section 6. The second wrap 11 is bonded to the remaining portion of the second filter section 6 and the tobacco rod 2 to join the filter portion 3 and the tobacco rod 2.

  FIG. 2 shows a state in which the long holes 13 of the first winding band 10 of the chip paper 9 shown in FIG. By configuring the filter part 3 and the chip paper 9 in this way, the second filter area 6 in which the filter area 5 on the mouthpiece side is connected to the tobacco rod-like part 2 around the longitudinal axis of the cigarette 1. It becomes possible to rotate relatively. By this rotation, the relative position between the perforated portion 8 of the second filter section 6 and the long hole 13 of the first tip winding band 10 is adjusted to adjust the ventilation state of the filter portion, that is, the strength of the tobacco 1. It can be changed as shown in FIG. By such a member that makes the air flow variable, the user can adjust the air flow of the cigarette filter by two lowest ventilation positions where the perforated portion 8 and the long hole 13 do not overlap at all, that is, two highest strength positions, Between at least one maximum ventilation position, i.e. the lowest strength position, between which the perforation 8 and the slot 13 are substantially perfectly aligned to introduce the maximum amount of air into the filter. It becomes possible to adjust.

  FIG. 3 is a cross-sectional view taken along the positions of the perforated portion 8 and the long hole 13 of the tobacco 1. As is clear from the figure, the relative positional relationship between the long hole 13 and the perforated portion 8 is changed by the relative rotation of the filter area 5 and the second filter area 6 on the suction side in either direction. Thereby, the amount of air introduced into the filter unit 3 during smoking of the cigarette 1 through the overlapping portion of the long hole 13 and the perforated unit 8 can be adjusted.

  In the example shown in FIGS. 1 to 3, the filter part 3 and the chipping 9 each have only one perforated part 8 and one long hole 13. However, the filter portion and chipping may have a plurality of perforated portions and a plurality of long holes, respectively, and in this case, no problem occurs in the filter function.

  According to the present invention, there is provided an indicator means that allows a consumer to visually grasp the strength of cigarette set by changing the ventilation level of the filter portion as described above.

  FIG. 4 shows a state where an example of the indicator used in the present invention is arranged at five different positions. 4A to 4E, the cigarette 1 with a filter according to the present invention has a first scale composed of an indicator portion, that is, a marker 20 formed on the winding band 11 on the rod-like portion side of the chip paper 9. On the wrapping band 10 on the mouthpiece side of the chip paper 9, a second scale composed of an indicator, that is, a marker 21 is formed. These two scales are separated by a transverse score line 12. Similarly to the present invention, the first indicator portion or marker 20 is formed on the wrapping band 10 on the mouthpiece side, and the second indicator or marker 21 is placed on the wrapping band 11 on the rod-like portion side adjacent to the wrapping band 10. It will be understood that it may be formed.

  FIG. 4A is an example of an indicator used in the present invention, showing the position when the cigarette is set to the highest level of strength. The user can recognize that it is the highest level of strength by seeing, for example, a state where only one end of each of the scales 20 and 21 is in contact with the horizontal cut line 12. When the indicator is at the position shown in FIG. 4A, it indicates that the perforated portion 8 and the long hole 13 (see FIGS. 1 to 3) are separated from each other. As the area 5 on the mouth side rotates and the band 11 on the rod side and the band 10 on the mouth side rotate relative to each other, the perforation 8 and the slot 13 begin to overlap, thereby causing smoke in the filter. The ratio of air to air is increased, thus reducing the strength of the cigarette. This is indicated by the relative positional relationship between the scales 20 and 21, as shown in FIG. 4B. When the scales 20 and 21 are symmetrical with respect to the transverse cut line 12 as shown in FIG. 4C, the perforations 8 and the long holes 13 are completely overlapped and the ratio of air to smoke is maximized, so that the cigarette strength is at the lowest level. It becomes. When the winding strip 11 on the rod-like portion side and the winding strip 10 on the mouthpiece side are further rotated relatively, the perforated portion 8 and the long hole 13 move away from each other, and the scales 20 and 21 are in the state shown in FIG. 4D. . As shown in FIG. 4E, when only one end of each of the scales 20 and 21 is in contact with the lateral cut line 12, the perforated part 8 and the long hole 13 are completely separated again, and the cigarette Is the highest level of strength.

  There are various aspects of the construction of the indicator, both in terms of its shape and position, which can provide further advantages in terms of higher accuracy of the indicator for the user and overall ease of use of the cigarette. Will be understood.
