SMOKING ARTI CLE Filed May '7, 1964 INVENTOR SI LAS A. MORE HOUSE tion of centrifugal force in United States Patent ington, D.C.
Filed May 7, 1964, Ser. No. 365,686
8 Claims. (Cl. 131--10.5)
to improvements in cigaparticularly with improved The present invention relates rettes and is concerned more smoking tips for cigarettes.
It is well known that cigarette smoke contains or entrains materials alleged to be injurious to the health of the smoker and that many efforts have heretofore been made to remove such harmful materials before the smoke enters the mouth. Such prior art efforts principally have embraced the use of filters of various materials and constructions through which the smoke is passed. Such filters have many attendant disadvantages, among them, the failure to remove or effectively to remove harmful materials, impedance of the smoke and ill effect upon the taste or flavor of the tobacco smoke.
The present invention has for its principal object the provision of'a smoking tip which avoids all the disadvantages of various filters and similar prior art devices and which in fact effectively removes harmful materials entrained with the smoke.
The invention in general embodies a structure includ-' ing a spiral path for passage of the smoke for generasired entrained materials, and absorbent materials adjacent the spiral path for absorbing the undesired materials so separated from the smoke.
Other objects and advantages will be apparent from the following detailed description taken in conjunction with the accompanying drawings wherein preferred embodiments of the invention are selected for exemplification.
In the drawings:
FIG. 1 is a perspective view of a cigarette having a the smoke to separate nude-- smoking tip constructed and arranged in accordance with the invention; 7
FIG. 2 is an enlarged front end view of FIG. 1; FIG. 3 is a fragmentary sectional view taken on the line 3-3 of FIG. 2;
FIG. 4 is a view similar to FIG. 2 but showing a modified form of the invention;
FIG. 5 is a fragmentary sectional view taken on the line 5-5 of FIG. 4;
FIG. 6 is a view similar to FIGS. 2 and 4 but showing a further modified form of the invention; and
FIG. 7 is a fragmentary sectional view taken on the line 7-7 of FIG. 6.
like numerals refer to like in smoking tip 12 and the usual integral rearward tobacco containing smoke generating portion 14.
The invention resides in the smoking tip portion 12 of the cigarette which is capable of a wide variety of specific body of the core and to divert the smoke in a spiral path around the periphery of the core. The spiral path surrounding the core imparts a centrifugal force to the smoke and is faced on its inner and outer sides by absorbent material for absorbing materials separated from the spiraling smoke.
The forms of the invention illustrated show a smoking tip having a central cylindrical core 16 of suitable rigid absorbent material preferably carbonaceous material, activated charcoal, for example. As shown, the inner end of the core 16 is provided with an impervious face 18 to prevent smoke from passing through the body of the core and to divert the smoke around the outer cylindrical surface of the core into a spiral path which may be defined in a number of ways.
In the form of the invention shown in FIGS. 2 and 3 a thin layer of absorbent material 20, which may be paper, encases the cylindrical wall of the core 16 and around this is Wrapped a strip of smoke impervious material 22, cork for example, in spiral convolutions to form a spiral path 24 for the smoke. An outer layer of absorbent ma terial 26 encircles the convoluted strip 22 to form the outer wall of the spiral path and, if desired, the usual tobacco covering 28 may be extended around the layer 26. An exterior sleeve 30 of moisture proof material of any suitable material for engaging the lips of the smoker, cork or white cellulose acetate for example, surrounds the paper layers 26 and 28 and may be employed in all constructions of the smoking tip.
In the form of the invention shown in FIGS. 4 and 5 a spiral path 32 is cut, molded or otherwise formed in the outer cylindrical surface of the core 16 so that the core itself may provide the inner absorbent surface of the spiral path. Similar paper layers 26 and 28 may also provide the outer absorbent surface of the spiral path 32.
In the form of the invention shown in FIGS. 6 and 7 the spiral path 34 may be formed in a sleeve 36 of any suitable absorbent material by molding or corrugating, for example, which encircles the cylindrical wall of the core 16. The sleeve 36 will then provide the inner absorbent surface for the spiral path 34 and again the layers 26 and 28 may provide the outer absorbent surface.
Although the exterior sleeve is shown as terminating flush with the outer end extremity of the smoking tip construction it is contemplated that it may, if desired, be extended outwardly beyond thereof or that any portion of the tip construction may be recessed within the outer extremity of the exterior sleeve.
It is to be understood that the invention is in nowise limited to the particular forms herein illustrated and described, which are for exemplary purposes only, but embraces all such modifications thereof as may come within the scope of the following claims.
I claim:
1. A smoking article for separating undesired materials entrained with the smoke which comprises, an axial centrally disposed elongated rigid core, an absorbent sleeve in contact with the elongated outer side of said rigid core, an outer absorbent sleeve, means forming a spiral path between said sleeves for the passage of smoke between said absorbent sleeves, the said sleeves absorbing undesired materials from the smoke during its passage through said spiral path.
2. The smoking article of claim 1 wherein the spiral path includes an added element which encircles and is a part of the core.
3. The smoking article of claim 1 wherein the spiral path includes an added spiral element which encircles and is a part of the core.
4. The smoking article of claim 1 core comprises carbonaceous material.
5. The smoking article of claim 1 wherein the rigid core is charcoal.
6. A smoking article comprising a tubular wrapper, a tobacco charge within said wrapper and at one end thereof, and a filter tip within said wrapper at the other end thereof, said tip comprising a rigid core of absorbent wherein the rigid material, an impervious strip convoluted about said core to form a spiral path for the passage of smoke from said tobacco, a sleeve of absorbent material surrounding and in contact with said strip, means effectively closing 011 the end of said core adjacent the tobacco charge whereby the smoke is diverted into said spiral path and undesired materials are removed by the absorbent sleeve and core, and an exterior sleeve of moistureproof material surrounding said tubular wrapper in the region of said filter tip.
7. The article of claim 6 wherein the diverting means for the smoke is an impervious surface at the inner end of the core.
8. The smoking article of claim 6 wherein the convoluted strip is a cork material.
