Parrigin, Tompkinsville, Ky. (162 St. Ann Drive, Lexington, Ky. 40502) Filed June 9, 1964, Ser. No. 373,809 4 Claims. (Cl. 131182) The present invention generally relates to a cigarette holder incorporating means therein for removing a relatively high percentage of allegedly harmful substances found in cigarette smoke, such as nicotine, tars and irritants of various types for preventing such substances from reaching the mouth of the person using the present invention.

Many attempts have been made to remove certain substances found in cigarette smoke including devices in the nature of a filter having various materials incorporated therein attached to the end of each cigarette. This procedure is rather costly and has various objections. The present invention is in the form of a cigarette holder which may be used with a plurality of cigarettes and incorporates therein a removable core which may be replaced within the interior of the cylindrical shell having a spiral groove or grooves extending from end to end thereof for the travel of cigarette smoke therethrough. The screen is provided between the core and the mouthpiece for further removing impurities from the cigarette smoke with the core having a rough or fuzzy surface adjacent the inner perimeter of the spiral groove for picking up and retaining impurities in the cigarette smoke.

Another object of the present invention is to provide a cigarette holder with a screen and replaceable core together with an ejector mechanism at the outer end thereof for securing the butt end of the cigarette in place and also enabling the cigarette butt to be more easily removed therefrom.

Still another object of the present invention is to provide a cigarette holder which is simple in construction, easy to disassemble, recondition and clean and relatively inexpensive to manufacture.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of the cigarette holder of the present invention illustrating a cigarette positioned therein;

FIGURE 2 is an exploded group perspective view of the components of the presentinvention;

FIGURE 3 is a longitudinal, vertical sectional view taken substantially upon a plane passing along section line 3-3 of FIGURE 1, on an enlarged scale, illustrating the structural relationship of the components of the invention;

FIGURE 4 is an end view taken substantially upon a plane passing along reference line 44 of FIGURE 3 with portions thereof broken away illustrating certain of the structural details of the invention;

FIGURE 5 is a transverse, sectional view taken substantially upon a plane passing along section line 55 of FIGURE 3 illustrating the structure of the groove in the inner surface of the shell and its relationship to the core;

FIGURE 6 is a transverse, sectional view with parts broken away, taken substantially upon a plane passing along section line 66 of FIGURE 3 illustrating the screen construction and its association with the remainder of the cigarette holder; and

FIGURE 7 is an exploded group perspective view with portions thereof shown in section for illustrating the struc- "ice tural arrangement of the extractor, shell and removable core.

Referring now specifically to the drawings, the numeral 10 generally designates the cigarette holder of the present invention for holding a conventional cigarette 12 with the butt end thereof received within the holder and the lighted end remote therefrom in a conventional manner. The cigarette holder 10 includes an elongated cylindrical shell 14 having :an internal spiral groove 16 communicating with the inner surface thereof and extending from end to end of the shell 14. One end of the shell 14 is provided with an internally threaded head portion 18 of increased diameter for receiving the externally threaded reduced end 20 of a tapered mouthpiece 22. The tapered mouthpiece 22 is provided with an enlargement 24 at the free end thereof for enabling the mouthpiece to be easily held in the mouth and also, the mouthpiece 22 is provided with a longitudinal bore or passageway 26 extending therethrough and communicating with a screen 28 which is received within the reduced end portion 20 of the mouthpiece 22 for screening the smoke entering the passageway 26.

Disposed within the shell 14 and substantially completely covering the inner surface thereof is .a removable and replaceable core 30 which engages the screen 28 at one end thereof and forms a closure for the inner edge of the spiral groove 16. The opposite end of the core 30 from the screen 28 may have a recess 32 defined centrally therein together with a plurality of radial slots or grooves 34 formed therein communicating with the spiral groove 16. The end of the core 36 is normally engaged by an end plate 36 having an enlarged central opening 38 and a plurality of smaller openings 40 therein for the passage of cigarette smoke into the recess 32 so that the smoke may then proceed outwardly through the radial grooves 34 into the spiral groove 16. The end plate 36 is mounted on the inner end of the sylindrical wall 42 having at its outer edge a laterally extending peripheral flange 44, terminating in a cylindrical wall 46 generally paralleling the wall 42 in spaced relation thereto. The inner end of the cylindrical wall 46 is thickened or provided with a ridge as at 48 which is roughened or knurled as at 50 for easy gripping. The wall 46 is provided with an L-shaped slot 52 therein for receiving a projecting pin 54 attached fixedly or detachably to the shell 14 for retaining the extractor structure 36-56 on the end of the shell but enabling it to rotate slightly and move longitudinally in relation thereto for ease of extracting a cigarette from the tubular socket or wall 42 which may be slightly tapered for frictionally gripping the ciagrette 12 when placed therein. As illustrated in FIGURE 7, the shell 14 is provided with an undercut portion 56 for receiving the wall 42 when the plate 36 abuts against the end of the core 39 and when in this condition, the end of the shell 14 engages against the inner surface of the flange or wall 44 as illustrated in FIGURE 3, thus securely retaining the cigarette butt ejector in place. The shell 14 is preferably constructed of a plastic material which may be of any suitable color or have any suitable decorative effect and the mouthpiece and ejector may also be constructed of plastic material if desired although other materials such as metal or the like may be employed for the various components without departing from the scope of the present invention.

As will be apparent, the device has a diameter only slightly larger than the diameter of a cigarette and it has been found that a grooved shell 14 from 2 to 3 /2 inches in length will be adequate for effectively cleaning the cigarette smoke and removing nicotines, tars, and the like therefrom.

The core 30 may be constructed of any suitable substance such as woven plastic, fiber or hard woven cotton cloth. The core does not obstruct the grooved spiral surface of the shell that carry the smoke but fits snugly in the shell which renders the grooves efficient for smoke passage and the core may have a rough or fuzzy surface and be absorbent in nature thereby removing some of the tar and other materials from the smoke as it passes over the core in a spiral path. As the smoke passes in the spiral groove, the smoke will be cooled thus precipitating out liquids or condensing liquids due to the decrease in temperature thus further removing tars and the like. By circulating the smoke around and around in a spiral pattern, additional heavy particles, liquids, tars and the like will be spun out of the smoke and condensed tars or the like that are still in the smoke when it passes through the screen will be solidified at the screen and there removed from the smoke before they enter the mouth of the smoker. The screen may be of metallic material or of fibrous material and is removable and can be cleaned and replaced or a new screen inserted when desired. This can be accomplished at the same time as the core is being replaced which should take place When the core has absorbed all of the materials that it can reasonably be expected to efficiently absorb.

The Wall 42 is split at 43 and will spring outwardly enough to clear the shell and this will remove the pressure on the butt permitting it to fall out of the butt ejector.

Due to the restricted volume of the spiral passageway or passageways, the velocity of the smoke passing through the groove or grooves will be relatively high so that it will impinge on the screen at a relatively high velocity thus serving to further increase the cleaning effect of the screen on the smoke before it enters the mouth of the smoker.

While the device has been illustrated and specifically described in combination with a cigarette, the holder may also be employed with cigars or incorporated into a pipe stern in an obvious manner.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling Within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A cigarette holder comprising an elongated tubular shell having a cylindrical bore extending therethrough, a mouthpiece mounted at one end of the shell and forming a closure for the bore, said mouthpiece having a longitudinal passage extending therethrough communicating With the bore through the'shell, a cylindrical core of absorbent material'disposed in said bore and having an exterior surface closely adjacent the interior surface of the bore, the interior surface of said bore having a spiral groove extending substantially throughout the length thereof, a cylindircal screen interposed between the mouthpiece and the core and communicating with the groove for transmitting smoke from the groove to the passage through the mouthpiece, a sleeve movably mounted on said shell remote from the mouthpiece, said sleeve telescoping exteriorly of the shell, a cylindrical socket attached to said sleeve and telescoping into the bore in the shell, said socket having openings in the inner end thereof for passage of smoke from the cigarette into the bore in the shell, and means interconnecting the sleeve and shell to limit relative longitudinal and rotational movement of the sleeve and socket in relation to the shell, said socket being longitudinally split and constructed of resilient material for radial expansion and contraction for frictionally gripping and releasing the end of a cigarette.

2. The structure as defined in claim 1 wherein said core is provided with a recess in the end thereof remote from the mouthpiece with radial grooves communicating with the recess thereby enabling passage of smoke from the end of the core to the spiral groove in the shell.

3. The structure as defined in claim 2 wherein said core is constructed with a rough fuzzy external surface for forming a closure for the inner surface of the groove whereby smoke passing over the peripheral surface of the core will have the liquid components thereof removed and absorbed by the core.

4. The structure as defined in claim 3 wherein said means interconnecting the sleeve and shell to limit relative longitudinal and rotational movement of the sleeve and socket in relation to the shell includes a radially projecting pin on the shell, said sleeve having a slot formed therein receiving the pin, said slot having closed ends and with a portion thereof extending longitudinally of the sleeve and a portion thereof extending peripherally thereof, said sleeve being longitudinally longer than said socket whereby the socket will be moved longitudinally externally of the sleeve when the pin on the shell engages the inner end of the slot to enable the split socket to radially expand to release a cigarette disposed therein, the inner end of said socket abuttingly engaging the end of the core when the pin on the shell is on the outer end of the slot thus restricting passage of smoke from the recess through the radial grooves in the end of the core.
