Description:
BACKGROUND AND OBJECTS
In the use of conventional mouthpieces for cigarettes and other tobacco products, the smoker draws air into the mouthpiece creating a suction which generates a vacuum in the area of the opening of the mouthpiece into which the cigarette is inserted, which sucks air needed for the combustion process of the cigarette through the mouthpiece, thereby drawing the resulting tobacco fumes into the mouth of the smoker. In this manner, the smoker inhales certain tobacco fumes which may be detrimental to health, even when these harmful components are partially inhibited by the customary filters provided within the cigarette or in the mouthpiece.
It is an object of this invention to provide a mouthpiece for cigarettes or other tobacco products which in one mode of operation, prevents substantially all of the noxious components of tobacco smoke from entering the smoker's mouth.
Another object is to provide an invention of the character described including a filter insert positioned in the mouthpiece, and having a lateral outlet between the ends thereof, so that air blown in the mouthpiece opening generates a vacuum at the cigarette end of the mouthpiece, so that the tobacco smoke sucked in the opening and the blown-in air is directed through the lateral outlet of the filter insert.
Another object is to provide mouthpiece of the character described includes a second mode of operation, wherein the smoking of the cigarette or other tobacco product is carried out in the normal manner.
DESCRIPTION OF FIGURES OF THE DRAWING
FIG. 1 is a fragmentary, longitudinal sectional view of a mouthpiece for cigarettes or other tobacco products constructed in accordance with the present invention;
FIG. 2 is a view similar to FIG. 1 of a modified form of the present invention;
FIG. 3 is a view similar to FIG. 1 of another modified form of the present invention, and
FIG. 4 is a view similar to FIG. 1 of a still further modified form of the present invention.
DESCRIPTION OF FORM OF INVENTION ILLUSTRATED IN FIG. 1
In FIG. 1 there is illustrated a mouthpiece constructed according to the present invention which includes a small tubular member 1, one end of which (not shown in the drawing) is inserted into the mouth. The opposite end of tubular member 1 is sleeved over the terminal of cylindrical, intermediate filter insert 2. A second small tubular member 3 is sleeved over the other end of intermediate insert 2, preferably at a distance of 1 to 3 millimeters.
A cylindrical nozzle plate 4 is fitted into tubular member 1, the nozzle plate being provided with an axial nozzle opening 5 which narrows conically towards the edge of intermediate insert 2.
Intermediate insert 2 is provided with two parallel ducts 6 and 7 which are angularly disposed with respect to the mouthpiece axis. One end of duct 6, extends from a peripheral edge of the front side of intermediate insert 2, adjacent nozzle plate 4, and extends to the diametrically opposite edge of the far end of insert 2. Duct 7 extends from the center of the aforementioned front side of intermediate insert 2 to that portion of the exterior perimeter of the central part of intermediate insert 2 which is exposed, and lies between tubular members 1 and 3.
Referring to FIG. 1, it will be seen that ducts 6 and 7 are in communication with an intersection 8 formed between nozzle plate 4 and intermediate insert 2, while duct 6 is additionally in communication with an opening 9 into which the cigarette or other tobacco product is placed. Duct 7 communicates with outlet 10 formed between tubular members 1 and 3.
The cross-sectional area of duct 7 is considerably larger than the smallest cross-sectional area of nozzle 5, and is slightly larger than the cross-sectional area of duct 6.
OPERATION OF FORM OF INVENTION ILLUSTRATED IN FIG. 1
In use of the mouthpiece of the present invention, the tobacco product, such as a cigarette or a cigar is inserted through opening 9 into tubular member 3, the cigarette or cigar being inserted in such a way that a space remains between insert 2 and the tobacco product.
The smoker places the mouthpiece into his mouth and blows in the direction indicated by arrow a in FIG. 1. The air passes through nozzle 5 and flows in the direction indicated by arrow b in duct 7, which creates an aspirating effect and generates a vacuum at intersection 8, duct 6, and in tubular member 3. This vacuum effects air suction from the combustion focus of the tobacco product, during which time the tobacco fumes are sucked through the tobacco product into the duct 6 and the intersection 8 respectively. They are then forced in the direction indicated by arrow c through the duct 7, together with the blown-in air, through outlet 10.
DESCRIPTION OF FORM OF INVENTION ILLUSTRATED IN FIG. 2
In the modified form of invention shown in FIG. 2, the small tubular member 11 and the small insert tubular member 13 are of unitary construction. An insert 14 is provided with a nozzle opening 15, which insert together with an intermediate part 12 which is provided with ducts 16 and 17, form a single component. Duct 16 is comparatively narrow, and is in communication with an opening 19 at one end of the mouthpiece. Duct 16 discharges in reverse direction to the nozzle opening 15 into a connecting space 18 from which the outlet duct 17 leads to an outlet opening 20 in the wall of tubular member 11, 13.
OPERATION OF FORM OF INVENTION ILLUSTRATED IN FIG. 2
As shown in FIG. 2, a smoker blows into the mouthpiece in the direction indicated by arrow a, creating a vacuum by the flow from the nozzle opening 15 in the duct 16 in the direction indicated by arrow b. This creates a vacuum in the area of opening 19 and, as a consequence, air is sucked from the combustion focus of the inserted tobacco product, and the fumes reach the outlet duct 17 traveling through duct 16 and space 18 in the direction indicated by arrow c.
The fumes are thereby laterally expelled together with the blown-in air. If desired, parts 11 and 13 can be of separate construction, as in the form of invention illustrated in FIG. 1.
DESCRIPTION OF FORM OF INVENTION ILLUSTRATED IN FIG. 3
In FIG. 3 there is illustrated a unitary small mouthpiece and tobacco product insert tube 21, 23. The mouthpiece is provided with a nozzle insert 24 of cylindrical construction, the insert being provided with a conical nozzle opening 25 coaxial to the mouthpiece axis. An angular tube 22 is positioned within tubular member 21, one end of which is aligned with and in spaced relation to nozzle 25 of nozzle insert 24. The inlet of angular tube 22 is considerably larger than the nozzle outlet, and the opposite end of the angular tube 22 comprises an outlet duct 27 which communicates with a wall opening 30 of tubes 21, 23.
The interior of part 23, which serves as the intake duct, designated 26, communicates with the insert opening and is connected with the outlet duct by the space 28 formed between the nozzle insert 24 and the angular tube 22.
OPERATION OF FORM OF INVENTION ILLUSTRATED IN FIG. 3
As shown in FIG. 3, when blowing into the mouthpiece in the direction of arrow a, the air flow is directed into duct 27 as indicated by arrow b. This creates an aspirating effect and generates a vacuum in space 28 of duct 26, and consequently in the area of the insert opening of member 23 (not shown) which is similar to opening 9 in the form of invention illustrated in FIG. 1.
Air is therefore sucked from the combustion focus of the tobacco product while the tobacco fumes are expelled together with the blown-in air in the direction indicated by arrow c, through duct 26, space 28 and duct 27, exiting through outlet 30.
The form of invention illustrated in FIGS. 1 to 3 do not have any movable components, and their manufacture and maintenance is therefore simple. However, the dimensions of positions of the various ducts must be adjusted with respect to each other in order to obtain a sufficiently powerful aspirating effect under standard air injection pressure.
In another mode of operation, the inventions shown in FIGS. 1, 2 and 3 may be used for ordinary smoking by placing a finger tip over the outlet 10, 20 or 30 while drawing through the mouthpiece.
DESCRIPTION OF FORM OF INVENTION ILLUSTRATED IN FIG. 4
In FIG. 4 there is illustrated apparatus for increasing the aspirating effect of the present invention mechanically. For this purpose, the above-mentioned mouthpiece, including the mouth insert and the tobacco product insert tube is indicated at 31, 33 as a single component which is provided with an axial member 42 rotatably supported at each end by bearing supports 41a, 41b. Adjacent bearing support 41a on the mouthpiece side, a pressure propeller 43a is fitted on axial member 42, while a suction propeller 43b is fixed to axial member 42 adjacent bearing support 41b for drawing air into the tubular member.
A conical nozzle casing 34 is mounted within insert tube 31 at the pressure side of propeller 43a, and a cup-shaped filter insert 32 which narrows downstream, forms an annular nozzle enclosing axial member 42. An annular duct 35a is formed between cup-shaped filter insert 32 and nozzle casing 34, the annular duct extending diagonally outward from, and downstream of the mouthpiece.
Annular duct 35a communicates with a ringlike space 38 formed between the outer edge of filter 32 and tobacco product insert tube 33. Space 38 gradually enlarges to form an outlet duct 37 which communicates with lateral wall openings 40. Beyond space 38, nozzle opening 35 is located at the pressure side of suction (intake) propeller 43b which forms the intake duct 36, and is therefore connected with the insert opening located on the suction (intake) side of the propeller 43b.
OPERATION OF FORM OF INVENTION ILLUSTRATED IN FIG. 4
When the smoker blows into the mouthpiece in the direction of the arrow a, propeller 43a is activated to direct air in the direction of arrow b, during which time the aspirating effect in space 38 creates a vacuum in communication with of the tobacco product opening. The vacuum causes air to move toward the combustion focus of the tobacco product while the fumes are directed through duct 36 to outlet openings 40. Since the axial member of propeller 43a is also activated, which activates the suction (intake) propeller 43b as well, the aspirating effect generated by the flow of air in the direction of arrow b in the space 38 together with the intake and ejection of the tobacco fumes in the direction of arrow c, are additionally increased.
While there has been herein shown and described the presently preferred forms of the present invention, it is to be understood that such has been done for the purpose of illustration only, and that various changes may be made therein within the scope of the claims hereto appended.
In the use of conventional mouthpieces for cigarettes and other tobacco products, the smoker draws air into the mouthpiece creating a suction which generates a vacuum in the area of the opening of the mouthpiece into which the cigarette is inserted, which sucks air needed for the combustion process of the cigarette through the mouthpiece, thereby drawing the resulting tobacco fumes into the mouth of the smoker. In this manner, the smoker inhales certain tobacco fumes which may be detrimental to health, even when these harmful components are partially inhibited by the customary filters provided within the cigarette or in the mouthpiece.

This creates a vacuum in the area of opening 19 and, as a consequence, air is sucked from the combustion focus of the inserted tobacco product, and the fumes reach the outlet duct 17 traveling through duct 16 and space 18 in the direction indicated by arrow c.
The fumes are thereby laterally expelled together with the blown-in air. If desired, parts 11 and 13 can be of separate construction, as in the form of invention illustrated in FIG. 1.
DESCRIPTION OF FORM OF INVENTION ILLUSTRATED IN FIG. 3
In FIG. 3 there is illustrated a unitary small mouthpiece and tobacco product insert tube 21, 23. The mouthpiece is provided with a nozzle insert 24 of cylindrical construction, the insert being provided with a conical nozzle opening 25 coaxial to the mouthpiece axis. An angular tube 22 is positioned within tubular member 21, one end of which is aligned with and in spaced relation to nozzle 25 of nozzle insert 24. The inlet of angular tube 22 is considerably larger than the nozzle outlet, and the opposite end of the angular tube 22 comprises an outlet duct 27 which communicates with a wall opening 30 of tubes 21, 23.
The interior of part 23, which serves as the intake duct, designated 26, communicates with the insert opening and is connected with the outlet duct by the space 28 formed between the nozzle insert 24 and the angular tube 22.
OPERATION OF FORM OF INVENTION ILLUSTRATED IN FIG. 3
As shown in FIG. 3, when blowing into the mouthpiece in the direction of arrow a, the air flow is directed into duct 27 as indicated by arrow b. This creates an aspirating effect and generates a vacuum in space 28 of duct 26, and consequently in the area of the insert opening of member 23 (not shown) which is similar to opening 9 in the form of invention illustrated in FIG. 1.
Air is therefore sucked from the combustion focus of the tobacco product while the tobacco fumes are expelled together with the blown-in air in the direction indicated by arrow c, through duct 26, space 28 and duct 27, exiting through outlet 30.
The form of invention illustrated in FIGS. 1 to 3 do not have any movable components, and their manufacture and maintenance is therefore simple. However, the dimensions of positions of the various ducts must be adjusted with respect to each other in order to obtain a sufficiently powerful aspirating effect under standard air injection pressure.
In another mode of operation, the inventions shown in FIGS. 1, 2 and 3 may be used for ordinary smoking by placing a finger tip over the outlet 10, 20 or 30 while drawing through the mouthpiece.
DESCRIPTION OF FORM OF INVENTION ILLUSTRATED IN FIG. 4
In FIG. 4 there is illustrated apparatus for increasing the aspirating effect of the present invention mechanically. For this purpose, the above-mentioned mouthpiece, including the mouth insert and the tobacco product insert tube is indicated at 31, 33 as a single component which is provided with an axial member 42 rotatably supported at each end by bearing supports 41a, 41b. Adjacent bearing support 41a on the mouthpiece side, a pressure propeller 43a is fitted on axial member 42, while a suction propeller 43b is fixed to axial member 42 adjacent bearing support 41b for drawing air into the tubular member.
