BACKGROUND OF THE INVENTION (a) Field of the invention The present invention is concerned with a cigarette holder, and more particularly, it relates to a cigarette holder which permits the user to easily remove its tarcollecting insert and to easily clean it or to easily replace the same with a fresh one.
(b) Description of the prior art Some of the known cigarette holders comprise cigarette holding members and mouthpiece sections. Said cigarette holding members comprise protrusions containing first straight smoke paths provided therein adjacent to the cigarette holding sockets, said first paths extending for a distance to terminate in the middle portion, of the'cigarette holding members. Near the closed end of this first smoke path, there are formed transverse narrow passageways to distribute the smoke stream sideways to lead the spread smoke streams to the adjacent area in which the smoke streams pass while being partially trapped by bulging formations provided on the external wall of the rear half of the protrusions. Here, a great difliculty is encountered in cleaning the narrow passageways in which tar is accumulated.
SUMMARY OF THE INVENTION It is, therefore, the object of the present invention to eliminate the aforesaid difiiculties which are encountered in the cigarette holders of the prior art when it was intended to remove the tar accumulated on the surface of BRIEF DESCRIPTION OF THE DRAWING FIG. 1 is a perspective view of the cigarette holder embodying the present invention;
FIG. 2 is a longitudinal sectional view, in an enlarged scale taken along the line IIII in FIG. 1;
FIG. 3 is'a cross sectional view taken along the line III-III in FIG. 2;
FIG. 4 is a perspective view, partly broken away, of the first tar-collecting insert member; and
FIG. 5 is another perspective view, partly broken away, of said first tar-collecting member, wherein the cover having a central narrow through-hole is shown detached from the cylindrical piece to which said cover is to be mounted.
DESCRIPTION OF THE PREFERRED EMBODIMENT In the drawing, reference numeral 1 represents a cigarette holding member having a recess 2 formed in the upper end portion having an open top end for allowing the insertion of a base portion of a cigarette to be held therein. Numeral 3 represents a mouthpiece member which is adapted to be detachably fitted in the central bore 6 which is so formed in the lower portion of the cigarette holding member 1 as to extend downwardly from the peripheral edge of the bottom wall 4 of said recess 2. This bottom wall 4 of the recess 2 substantially separates the recess portion 2 of the cigarette holding member 1 from said bore portion 6 provided in the lower section of the cigarette holding member 1. This bottom wall 4 is pro- 'vided with a through-hole 5 formed centrally therethrough to communicate with the bore 6. Said bottom wall 4 may be tapered on the face on the side adjacent to said recess 2 so as to guide the smoke emitted from the cigarette to said central through-hole 5. A first tar-collecting insert member which is indicated generally at 8 and which will be described in detail later is fitted in the bore 6 of said cigarette holding member 1, and a second-tar-collecting insert member 9 is fitted in the bore 7 of the mouthpiece member 3 which will be described later also. Said first tar-collecting insert member 8, in this embodiment, is made as an integral body, from an appropriate rigid and tough and incombustible material such as a hard synthetic resin or metal. Said first tar-collecting insert member 8 is molded or cast into an article consisting of a hollow cylindrical piece 10 having a configuration and size suitable for being detachably fitted in the bore 6 in slidable close contact with the inner wall of said bore 6, and having a perforated bottom-wall 11 and also having a solid rod 12 extending through the central portion of said bottom wall longitudinally thereof. The portion of said rod extending upwardly in the cylindrical piece 10 has a flat top face 12 Said bottom wall 11 is provided with a plurality of perforations as at-13 which are scattered around said central rod 12. The cylindrical piece 10 is provided, around the-inner peripheral edge of the open top end thereof, with a shouldered portion 10 A round cover 15 which is made with the same material as that of the cylindrical piece 10 and which has a narrow central through-hole 14 and which has a size allowing the cover to be fitted snugly onto the shouldered portion 10 and a thickness corresponding to the depth of the shouldered portion so that the plane of the upper face of the cover 15--when placed on said shouldered portion 10 -is substantially aligned with the edge of the upper opening of the cylindrical piece 10. Said solid rod 12 extends upwardly from the bottom Wall 11 of the cylindrical piece 10 for a distance such that there is left a narrow clearance between the flat top face 12 of the rod 12 and the bottom face of said cover 15, thus the rod facing the narrow through-hole 14.0f said cover 15. The lower portion face of the bottom wall 11 of the cylindrical piece 10 is' so shaped that a step is formed around the circumference thereof for a short distance below said lower face of the bottom wall 11 of the cylindrical piece 10 in such a way that the portion of the rod located above said stepped portion has a diameter which is the same as the diameter of the portion of the rod extending upwardly in the cylindrical piece 10 and further that the portion of the rod extending downwardly from said step has a diameter smaller than that of the portion located above said step as best seen in FIG. 2.
The second tar-collecting insert member 9 may be made with the same material as that of the first tar-collecting member 8 or from a metal or a non-inflammable hard synthetic resin. This second tar-collecting insert member 9 is of tubular shape having a longitudinally extending central bore 16 having an inner diameter corresponding to that of the lower portion of the rod having a smaller diameter so as to snugly and detachably receive said lower end portion 12 f the rod 12. This tubular second tarcollecting insert member 9 is provided, around the external circumference thereof, with a helical thread of many turns. The external edges of the thread are of a diameter such that they are slidable along the inner wall of the bore 7 and in close engagement therewith of the mouthpiece member 3 to form therewith a helical passageway 17 of many turns. This second tar-collecting insert member 9 is received in the central bore 7 of the mouthpiece member 3. Said mouthpiece member 3 has a longitudinal central channel 18 formed downwardly through the central longitudinal axis thereof in such a way that the uppermost end of said channel 18 communicates with the lower end of the bore 7.
After the respective parts of the cigarette holder have been assembled together in the manner as shown in FIG. 2, a cigarette is inserted in the recess 2 of the cigarette holding member 1 of the cigarette holder. The lower end portion of the mouthpiece member is held in the smokers mouth while lighting the free end of the cigarette. Then, suction is applied to the other end of the cigarette by the mouth of the smoker through the channel 18 of the mouthpiece member 3. Whereupon, the smoke emitted from the cigarette will pass through the central throughhole formed in the bottom wall of said cigarette receiving recess 2 while being guided by the tapered face thereof, and then through the narrow central through-hole 14 of the cover 15, and will travel through the clearance formed between the lower face of the cover 15 and the top flat face of the solid rod 12 to impinge against the fiat top face of the latter. Wherefrom, the current of the smoke is directed, due to the suction, radially and passes through the space in the cylindrical piece 10 around the external circumference of the solid rod 12 and flows through the perforations 13 formed through the bottom wall 11 of the cylindrical piece 10. Thence, the divided currents of smoke which have entered into the space in the bore 7 of the mouthpiece .member 3 are united. The resulting current of smoke which is "drawn by suction is caused to proceed through the helical passageway 17 which is formed between the inner wall of the bore 7 and the external wall and thread of the second tarcollecting insert member 9. Therefrom, the current of smoke is sucked into the central channel 18 and is discharged into the mouth of the smoker from the terminal open end of this channel 18. During the passage of the smoke, it passes quickly through the hole 14 which is formed in the cover which rests on top of, the cylindrical piece 10 of the first tar-collecting insert member 8 and impinges against the flat top face 12 of the solid central rod 12, altering its direction of travel radially. During this period, the
therefrom to deposit on the rear or the lower face of the cover 15 and also on the flat top face 12 of the solid central rod 12. The smoke which has been removed of the majority portion of tar therefrom during the foregoing travel proceeds further through the perforations 13 which are formed in the bottom wall 11 of the cylindrical piece 10. Duringthe passage of smoke through said perforations, some of the tar is separated to adhere to the edges of these perforations 13. As the smoke proceeds therefrom through the many turns of the long helical passageway 17, most of the remaining tar contained in the smoke is separated and deposits on the faces of this passageway 17. Thus, the smoker will either puff or inhale the resulting smoke which has been already stripped of most of theharmful tar contained in the smoke initially emitted from the burning cigarette and sucked through the cigarette holder.
