Parrigin, 162 St. Ann Drive, Lexington, Ky. 40502 Filed Dec. 10, 1965, Ser. No. 513,036 3 Claims. (Cl. 131-202) ABSTRACT OF THE DISCLOSURE A cigarette holding barrel has a bore divided by an annulus into a forward socket and rearward smoke passage. A core is fitted through the downstream end and abuts the annulus. An encircling helical thread provides the tortuous smoke spiralling and cooling groove. The headed ends of the core are flat-faced and have unique L-shaped kerfs communicating with the respective ends of the groove. A filtering screen is retained by the shoulder of the cup portion of the mouthpiece.

This invention relates to a cigarette holder embodying a barrel having novel means therein which acts on noxious agents and constituents of the main stream of the smoke in a manner to reduce temperature, cool the smoke and diminish the toxic action of certain components, such as nicotine, tars and other known irritants, whereby to condition and render to the thus treated smoke less harmful to the smoker.

Briefly, the holder herein recommended comprises a plastic hollow open-ended barrel, a plastic mouthpiece removably mounted thereon, a removable specially designed smoke traversing and spiralling plastic core, and a suitable screen in the barrel interposed between the core and mouthpiece.

The barrel is provided with a smooth-walled bore and rearwardly of the forward end with an integral centrally apertured annulus which defines a socket for an end portion of the cigarette and also an elongated chamber for the core. One side of the flange-like annulus defines a limit stop or abutment for the cigarette and the other rearward side provides a similar stop or shoulder for a coacting end of the core. The rearward end of the barrel is tapered and has an external rib which snaps conformingly but releasably into the receiver portion of a cup carried by the mouthpiece, the latter having a keeper channel or groove for said snap-action rib.

Those 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 View in side elevation of the improved cigarette holder constructed in accordance with the principles of the present invention;

FIGURE 2 is a central longitudinal view with parts in sect-ion and elevation;

FIGURES 3 and 4 are transverse or cross-sectional views taken on the section lines 3-3 and 4--4, respectively, these views being on an enlarged scale; and

FIGURE 5 is a central longitudinal sectional view through the smoke spiralling core taken on the section line 55 of FIGURE 2.

The over-all cigarette holder is characterized by a barrel 8, an attachable and detachable mouthpiece 10, an insertable and removable smoke traversing and spiralling core 12. and screen means 14.

The component parts 8, and 12 are made of a suitable grade of commercial plastics. The barrel 8 and mouthpiece 10 may be transparent or non-transparent. The core 12 is preferably solid and non-transparent.

More specifically, the barrel 8 is of elongated form and the principal body portion is cylindrical in form. The forward terminal end is denoted at 16. The opposite tapered end is denoted at 18 and is provided short of the rearward end with an encircling rib 20. On the interior of the barrel, which is open at its ends, is provided inwardly or rearwardly of the forward end with an annulus or flange 22 provided with a central smoke inlet opening or orifice 24. This collar acts as a divider and transforms the barrel into a socket 26 which is adapted to removably receive an end portion of the cigarette 28 as shown in FIGS. 1 and 2. The major portion of the barrel constitutes an elongated chamber 28 which fully encloses and shields the bodily insertable and removable core 12. It will be noted that the surfaces of the wall portions of the socket and chamber are uninterruptedly smooth and that the chamber is of a length appreciably greater than the socket to fully enclose the core 12. The forward of lefthand end of the annulus or collar 22 provides a limit stop shoulder for the end of the cigarette as shown in FIG. 2. The opposite or righthand surface of the annulus or collar provides a limit stop or shoulder for the adjacent coacting end of the core 12.

The mouthpiece 10 comprises a hollow stem 30, the hollow portion providing a smoke passage 32. The outer or rearward end portion is provided with an encircling bead 34 providing a suitable grip. The forward end portion of the stem or neck is provided with an enlarged cup-like receiver 36 whose interior is tapered to adaptably telescopingly receive the tapered end portion 18 of the barrel. In addition, the median port-ion of the Wall in the cup is provided with a shallow endless channel 38 which provides a keeper seat for the assembling and retaining rib 20. In practice the character or characteristics of the plastic will provide a slight yielding action so that the retaining rib 20 can be snapped releasably into the keeper seat or channel 38 as shown in FIG. 2. The screen 14, which may vary in construction for satisfactory filtering purposes is located at the juncture of the bottom of the cup receiver and adjacent end portion of the barrel.

With reference to FIG. 5, it will be seen that the core 12 takes the form of a helical feed screw. Accordingly, it embodies an axial solid shaft 40 which is circular in cross-section and uniform in cross-section from end to end. The screwthread means is wound around the periphery of the shaft between the solid enlarged end portions 43 and 44. The threads are adequately spaced from each other to provide the smoke traversing groove means. It will be noted, too, that each thread is of appreciable crosssection and that the peripheral surface thereof is substantially flat or planar as denoted at 41, these surfaces being spaced slightly from the substantially parallel surfaces of the wall portion of the core chamber. One straight across end portion of the core is denoted at 46 and the other like end portion at 48. The end portions 43 and 44 are of the same cross-sectional dimension so that the core is readily reversible and so that either end can be directed forwardly. Each end portion is also grooved or recessed in a like manner. This is to say one end portion 46 for example is provided with a diametrical kerf 50 extending thereacross and gradually increasing in depth from one peripheral surface and communicating with a companion angularly disposed ancillary groove 52, the latter being formed in the end portions 43 and 44 only and being diametrically opposite the peripheral surface (of the top in FIG. 5) and communicating with an adjacent coacting end of the smoke spiralling groove means in an evident manner.

Since the mouthpiece 10 can be readily applied and removed when the two components 8 and 10 are assembled as shown in FIGS. 1 and 2, a reliable and satisfactory 3 relationship of parts is assured. The use of a screen 14, or an equivalent tar trap, acts on the treated smoke before it enters the passage 32 and further slows down the speed of the smoke stream and contributes to the overall temperature reducing and cooling etfect which is had. The flat helical threads 41 with the substantially fiat surfaces 42 in close spaced proximity to the wall surface of the chamber 28 provides highly effective groove means. The solid end portions 43 and 44 (in FIG. 5) with the added tapering kerf 50 and communicating companion groove 52 accomplish the desired smoke intake at the forward end and smoke discharge at the rearward end of the barrel. It follows that the structural features and characteristics each contribute a proportionate share to the production of a cigarette holder which well serves the purposes for which it is intended, namely, to effectually cope with the hazards to health now attributed to cigarette smoking.

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.
