Definitions

• This invention is directed to dispensing devices generally, and more particularly -to devices adapted for personal use by a smoker to introduce a quantity of treatment fluid into a cigarette, cigar or a charge of pipe tobacco to modify the character of the combustion products produced by smoking.
• Devices of the invention disclosed herein are characterized by their convenience and effectiveness in use by the smoker, as well as their simplicity and economy of manufacture.
• Tobacco treatment devices intended for consumer use have frequently been proposed, an example of one such device pertinent to this invention being illustrated and described in U.S. Patent No. 3,677,269.
• the device contains a compartment within which a cigarette is placed by the smoker, after which a bellows element of the device is operated to induce a pressure differential between opposite ends of the ciga ⁇ rette, and a charge of treatment fluid is sumultaneously introduced and caused to be drawn into and to permeate the tobacco.
• That prior device has a relatively complicated mechanical design and is difficult to mass produce economi ⁇ cally; moreover it lacks complete suitability for average consumer use.
• Many other devices ranging from rather elemental types such as those illustrated in U.S. Patent Nos. 2,333,049 and 3,319,632, to more complex arrangements such as those illustrated in U.S. Patent Nos. 3,636,959, 3,732,872 and 3,847,162, are representative of prior known devices thought to be most pertinent to the invention

• Figure 2 is a top plan view of the device of Figure 1;
• Figure 3 is a sectional view taken on line 3-3 of Figure 2;
• Figure 4 is a side elevational view of a molded base element forming part of the device
• Figure 5 is an end elevational view of the base element
• Figure 6 is a side view of a restrictor plug removably receivable in the base element
• Figure 7 is a sectional view on line 7-7 of Figure 6;
• Figure 8 is a side view in cross section of a modified form of device.
• the treatment device.20 seen in Figures 1 and 2 comprises a hand-held unit which conveniently may be approximately the same size as a conventional cigarette lighter.
• the device here illustrated is adapted more -3-
• an outer casing 22 supporting an upwardly open cigarette receiver 24 and a conventional valved aerosol dispenser in side-by-side arrangement.
• the aerosol dispenser is in inverted position in casing 22 so that only the closed bottom end of dispenser 26 is exposed.
• the user inserts a cigarette into the exposed end of receiver 24, usually immediately prior to- smoking the cigarette, and depresses the exposed end of aerosol dispenser 26. This releases a charge of treatment fluid which is injected into the cigarette, as will be further explained below.
• casing 22 is typically formed of molded plastic to provide a generally cylindrical structure open at its lower end 28 and having an upper end wall 30 (see Figures 1 and 2) partially closing that end bf the casing. As here illustrated, casing 22 is of roughly eliptical cross-section since the receiver 24 and dispenser 26 are slightly different in diameter.
• the bottom or open end 28 of receiver 22 is adapted to receive and retain a base 32, preferably again of molded plastic, which is fitted in open .end 28 and forms a closure for that end of the casing.
• Base 32 is formed with a pair of pedestals 34, 36 which project upwardly within casing 22 in side-by-side relation.
• Pedestal 34 has a central or axial passage 38, and pedestal 36 likewise has an axial passage 40, both of these passages being in communication with a transverse passage 42 at spaced points along the latter.
• Pedestal 34 is provided with a socket 44 in its upper end which communicates internally with passages 38 and 42. Socket 44 is adapted to receive and make a fluid tight coupling with the tubular valve stem 46 of typical aerosol dispenser 26 so that when fluid is discharged
• a hollow injection needle 48 is secured, point upwardly, in passage 40 of pedestal 36.
• the lower end of needle 48 communicates with passage 40 to allow fluid to enter the needle and to be discharged through ports 50 provided in spaced relation along needle 48.
• Receiver 24 is superimposed on pedestal 36, an aperture 52 being formed in the closed lower end of the receiver to permit the needle to pass freely upwardly substantially centrally of the receiver.
• the upper end wall 30 of casing 22 is apertured at 52, 54 to provide access openings which are axially aligned, respectively, with pedestals 34 and 36.
• a restricter plug 56 is removably received in transverse passage 42 of base 32.
• Plug 56 has an enlarged head 58 which makes a fluid tight fit in the open end 60 of passage 42 in order to form a closure at that end of the passage.
• Plug 56 also has a stem 62 whose diameter is essentially the same as that of passage 42.
• Stem 62 has a flattened axially extending face 64 providing a segment-shaped clearance between the plug and the wall of passage 42 which thus forms a restriction in the passage between pedestals 34 and 36.
• the degree of restriction can be easily controlled in manufacture of the device by the amount of flattening of the stem in order to provide and desired degree of restriction. This is easily modified in manufacture to adapt the ' treatment device for different rates of application of the treat ⁇ ment fluid. In general it is preferred to control the total amount of treatment fluid by employing a suitably selected conventional aerosol metering valve in the -5-
• aerosol dispenser such as that shown in U.S. Patent Nos. 3,185,356 or 2,932,432, each of these is designed to dispense a predetermined measured amount of fluid product on each actuation of the dispensing valve.
• the modified device illustrated in Figure 8 is essentially identical to that described above except that provision is made for incorporating a spare aerosol dispenser within the casing.
• casing 122 is elliptically elongated to accommodate the extra dispenser 126 alongside the active dispenser 26.
• Dispenser 126 is also supported in inverted position in the casing but in this case the ferrule of the valve rests on a peg 170 formed in base 132 so as to space valve stem 146 out of contact with the base, and thus prevent actuation of the valve.
• the upper end wall of casing 122 is provided with an additional access opening- 152 through which dispenser 126 is inserted to place it in the storage position illustrated.
• dispenser 126 is inserted to place it in the storage position illustrated.
• the active dispenser 26 is exhausted, it is withdrawn and replaced by the spare 126.
• the modified device of Figure 8 corresponds to that of Figs. 1 to 3 in mechanical structure and operation.
