MILTON O. SCHUR FIG-4 IVE! nited States CIGARETTE Milton 0. Schur, Asheville, N.C., assignor to Olin Mathieson Chemical Corporation, a corporation of Virginia Filed Nov. 17, 1958, Ser. No. 774,361

1 Claim. (Cl. 131-9) The present invention relates to cigarettes and in particular to a tipped cigarette.

The language tipped cigarette is utilized to denote that class of cigarettes, conventional or filter type, wherein a band of paper is disposed about the end of the cigarette which is introduced'into the mouth of the smoker.

For example, tipping may take the form of a paper band simulating a band of cork or the like. i

A particular feature of the invention is the provision of a cigarette having a novel structure.

A further feature of the invention is the provision of a tipped cigarette where the tipping material is formed with a porous structure or with microscopic openings.

A further feature of the invention is the provision of a tipped cigarette where the tipping material is formed with a plurality of openings of such small size that they are not obvious and are scarcely perceptible to normal vision.

A further feature of the invention is the provision of a cigarette including a column of tobacco, a wrapper, and a band of tipping paper jacketing the wrapper where the wrapper is formed with at least one obvious opening While the tipping paper is porous or otherwise formed with a plurality of obscure openings; the tipping paper jacketing the wrapper so that the porous structure of the tipping paper registers with and overlays the wrapper opening.

A cigarette forming an exemplary embodiment of the invention and embracing the principles thereof may comprise a column of tobacco, a Wrapper encircling the tobacco, said wrapper being formed with at least one opening and tipping paper disposed about the cigarette so as to enclose and overlay at least a portion of the wrapper, at least a portion of the tipping paper being of a porous structure, the tipping paper being so disposed with respect to the wrapper that some of the porous structure registers with the wrapper opening.

Other features and advantages will become more apparent from the succeeding specification when read in conjunction with the appended drawings in which:

Fig. 1 shows a cigarette with which the principles of the present invention may be utilized;

Fig. 2 is a showing of a portion of the cigarette of Fig. 1 somewhat enlarged and with portions broken away for clarity;

Fig. 3 shows an alternative embodiment of the invention wherein the wrapper extends the full length of the cigarette;

Fig. 4 illustrates an example of porous tipping paper; and,

Fig. 5 shows obvious openings in the wrapper band.

Referring now to the drawings, specifically Figs. 1 and 2, there is shown a cigarette indicated generally by the reference numeral comprising a column of tobacco 11 atent O ice enclosed by a wrapper 12 and including an abutting filter plug 13.

The filter plug and the wrapper column of tobacco are joined in abutting relationship by a band 14 of tipping paper in well known fashion.

The wrapper 12 is formed with a plurality of openings 16 while the tipping paper includes an area or ribbon of obscure openings (shown somewhat enlarged for clarity) indicated by the reference numeral 17.

As in apparent in Fig. 2, the tipping paper is so disposed with respect to the wrapper 12, that some of the openings in the tipping paper fall into register with the wrapper. In this fashion, there is provided a conduit from the atmosphere to the interior of the cigarette so that the smoker upon taking a drag induces air to enter the conduits.

A convenient way of characterizing the openings in the tipping and in the wrapper and a convenient aid in defining the relative size of the tipping openings as against the wrapper openings is to refer to the former as being microscopic in size while the latter openings are macroscopic.

Furthermore, it is intended that the tipping band be securely fixed to the cigarette body as by gluing.

Fig. 3 shows an alternative embodiment of the invention wherein a Wrapper having macroscopic openings 160 is shown enclosing a column of tobacco 110 and a filter plug so that the wrapper extends the full length of the body of the cigarette. v

The tipping paper shown jacketing the wrapper is formed with a band of microscopic openings which fall in register with the openings160.

Obviously the plug 130 may be replaced with tobacco so that a still further embodiment of the invention may be constructed so as to embrace nothing but tobacco within the wrapper portion thereof.

Figs. 4 and 5 show typical tipping material in the form of paper band 18 having a ribbon of microscopic openings 19 and a typical wrapper paper 21 having macroscopic openings 22 respectively.

Obviously the width and finish of the tipping paper, indeed, the material from which the tipping is fabricated, is not critical.

Correspondingly, the size, number and conformation of the holes 22 is not critical so long as the cigarette embracing these elements is constructed in accordance with the preceding description of the invention.

' It is intended that a cigarette constructed in accordance with the principles of this invention will be effective when smoked to bring about the introduction of air into the body of the cigarette through the lateral or side openings formed in the tipping and in the wrapper in addition to the normal draught of air that is drawn longitudinally through the burning cone and the column of tobacco of the cigarette.

Obviously a wide variety of opening structures can be devised, i.c., the area of the openings in the wrapper may be increased or decreased to increase or decrease the volume of air drawn thereto, without departing from the spirit and scope of the invention.

What is claimed is:

A cigarette comprising a colunm of tobacco, an abut ting filter plug, a wrapper encircling the column of tobacco, a band of tipping material encircling the wrapper and the plug, said wrapper being formed with at least one macroscopic air opening in a margin thereof adjacent said plug, said tipping material being fixed to the wrapper and being formed with a plurality of microscopic air open.-

ings, said microscopic openings being circumferentially disposed about said tipping material, the tipping material overlaying the wrapper and being so positioned with respect to the wrapper that a least some of the microscopic openings fall in register with the wrapper opening to provide communication from the atmosphere to the interior of the cigarette through the tipping material and through the wrapper, said tipping openings being scarcely perceptible to normal vision.
