Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to cigarettes, and more particularly to adjustable cigarettes that allow for free air dilution of smoke over a wide range of degrees.

Prior patents disclose various filtered adjustment mechanisms designed to adjust the degree of air dilution to cigarette smoke. While a number of filter adjustment mechanisms have been disclosed, a simpler mechanism is schematically described herein, which includes one or more apertures in a substantially air-impermeable wrap around a filter plug. a substantially air-impermeable tipping paper (having apertures aligned with the apertures) is superimposed and affixed to the wrapper; By providing a sleeve adapted to be moved in a direction or rotatable, forming one or more apertures in the sleeve, and then rotating or moving the sleeve in an axial direction. The degree to which the two sets of apertures are aligned can be adjusted.

In other adjustment mechanisms, the filter plug is adapted to move axially within a cylinder formed by tipped paper, with an aperture formed in the tipped paper and a wrapper wrapped around the filter plug. The windings are also formed with corresponding apertures, thus allowing the degree of alignment of the two sets of apertures to be varied and the degree of air dilution to be adjusted by not moving the filter plug axially.

The problem with these adjustment mechanisms is that the sleeve and filter plug tend to come off the cigarette, and once they come off, it is difficult to put them back in place. Yet another problem is that conventional cigarette manufacturing machines cannot be readily applied to high-speed production of these products.

The present invention is a smoking article comprising a column of combustible smoking material and an end area open to allow air and smoke to pass through, the end area being a surrounding area suitable for the passage of air. the peripheral region is surrounded by a substantially air-impermeable sheet material, the sheet material comprising a first band secured to the mouth end region of the smoking article and the peripheral region. a second band that is movable relative to the mouth end area and is adapted to vary the amount of air admitted into the end area to dilute the smoke in the end area.

In one preferred embodiment, the mouth end section includes a filter plug opposite the post, the filter plug comprising a substantially air permeable wrapper, a substantially air permeable first tipped paper; and a second substantially air-impermeable tipping paper, the first tipping paper extending from the mouth end of the filter plug to a position on the post adjacent the post end of the filter plug. the second tipping paper extends from the mouth edge to substantially the columnar end of the first tipping paper, and the second tipping paper has an opening secured to the first tipping paper. a smoking article that is divided into an end sleeve and a columnar end sleeve that is movable axially over the first tipping paper and adapted to expose the air permeable first tipping paper to varying degrees; There is.

Cigarettes of the present invention can be manufactured using conventional cigarette manufacturing equipment with only minor modifications. and,
A cigarette is obtained in which the mechanism for adjusting the degree of air dilution does not come off the filter plug.

The cigarette of the present invention will be described in detail below with reference to the accompanying drawings. Fig. 1 is a perspective view showing one step in manufacturing the cigarette of the present invention, Fig. 2 is a perspective view showing the completed cigarette, and Fig. 3 is a perspective view showing the cigarette after it has been adjusted to an appropriate degree of air dilution. It is a perspective view showing a cigarette. In these figures, 2O1 is a tobacco rod, 202 is a filter plug, 203 is a substantially air permeable wrapper, 204 is a substantially air permeable first tipping paper, 205 is a filter plug 202 and a tobacco rod 201 206 is a substantially air-impermeable second tipping paper, 207 is an end sleeve that is part of the second tipping paper, and 208 is a part of the second tipping paper. A certain rod end sleeve 209 connects the mouth end sleeve 207 to the first tipped paper 20.
4 is the adhesive to be fixed, 210 is the second chip attaching paper 20
6 into a mouth end sleeve 207 and a rod end sleeve 208.

A conventional cylindrical filter plug 202, which may be cellulose acetate, is wrapped in an air permeable wrapper 203. This wrapped filter plug 20
2 are arranged in axially aligned end-to-end relationship with the tobacco rod 201, and a substantially air permeable first tipping paper 204 is wrapped around the filter plug 202 and the tobacco rod 201.2. to join. This number
String paper 204 extends from the mouth end of filter plug 202 to a location on the tobacco rod adjacent the rod end of the filter plug. A circumferentially extending band of adhesive is applied to the inner surface of the first tipped paper 204, and the center line of this band is aligned with the filter plug 204.
on either side of the border 205 between the filter plug 202 and the tobacco rod 201;
It straddles the.

A substantially air-impermeable second tipping paper 206 extends from the mouth end of the filter plug 202 to the rod end and surrounds the first tipping paper 204 . The second tipping paper 206 is formed with a row of closely spaced perforations 210, which separates the second tipping paper 206 into an end sleeve 207 and a rod end sleeve 208. . The end sleeve 207 is secured to the first tipping paper 204 adjacent its end by adhesive 209.

The rod end sleeve 208 is not bonded to the first tipped paper 2.4 with any adhesive.

The second tipping paper 206 is substantially air impermeable and the rod end sleeve 208 is separable along the row of perforations 210. With the rod end sleeve 208 attached to the mouth end sleeve 207, the cigarette has a set air dilution. If desired by the smoker, the end sleeve 208 may be rotated to separate the end sleeve 208 from the mouth end sleeve 207. and rod end sleeve 208
move in the axial direction. This exposes the substantially air permeable first tipping paper 204 from below the rod end sleeve 208. The exposed area of the first tipped paper 2o4 changes depending on the distance of movement of the rod end sleeve 208 in the axial direction. The amount of air sucked changes depending on this exposed area. Thus, the smoker can adjust the degree of air dilution of cigarette smoke as desired. This axially slidable rod end sleeve 208 is prevented from being removed from the mouth end of the cigarette by means of the mouth end sleeve 207.

In another embodiment of the invention, not shown, the filter plug wrapper and the first tipping paper are substantially air impermeable with a plurality of apertures formed therethrough. The plurality of apertures are exposed by moving the rod end sleeve 208 axially toward the coal end (smoking end) opposite the mouth end.

Cigarettes of the present invention can be readily produced in conventional cigarette manufacturing equipment with minor modifications. Forming the cigarette rod, forming the filter plug, and cutting these to length are conventional. In addition, arranging the filter plugs in an axially straight, end-to-end relationship with the cigarette rod and wrapping the first tipping paper around them means that the adhesive applicator is part of the first tipping paper. This is accomplished in the same manner as a conventional cigarette, except with the modification that adhesive is applied only to the area near and on both sides of the filter plug and tobacco rod interface (i.e., the area near and on both sides of the filter plug and tobacco rod interface). Similarly, the second tipping paper is similar to the first tipping paper except that the glue applicator is modified to apply a band of glue only to the end sleeve portion of the second tipping rim. accomplished in the same way.

The row of perforations 210 in the second tipped paper 206 is preferably performed in advance, such as by laser perforation, electrostatic perforation, or mechanical perforation using a needle or knife.1. Can be formed by any conventional means. To make the perforations very small, it is preferable to use a laser device, through which the tipped paper is fed in a running manner through the perforation zone, and on which the laser beam is focused. . The running speed of the chipped paper, the intermittent light emission during the laser beam, and the focusing degree are 21.0 perforation row in Fig. 2.
is chosen so that the tipping paper can be separated by the smoker into two parts, the end sleeve 207 and the rod end sleeve 208, along the line. Approximately 100 perforations are made each inch, preferably using a laser device.

Various modifications can be made to the embodiments described above.

For example, a mouthpiece without a filter plug may be used.
