Description

Aroma suction tube

The present invention relates to an aroma suction pipe for extracting aroma released from a source of aroma with air.

Such an aroma inhalation tube is disclosed, for example, in Patent Document 1. The smokeless tobacco of Patent Document 1 has a tubular pipe body having a mouthpiece that is removably inserted into one end of the pipe body, and is housed inside the pipe body. The aroma produces a cartridge. Here, the aroma is produced by filling the interior with, for example, cut tobacco, and the tobacco is added with a desired fragrance.

According to the above-mentioned smokeless tobacco, the user can suck through the nozzle, thereby obtaining a feeling similar to smoking. In detail, since the aroma is filled with the shredded tobacco and the aroma component volatilized from the fragrance, the user can absorb the air containing the aroma component and taste the aroma component.

On the other hand, in order to make the above-described aroma generation easy to replace, it is conceivable to apply the tobacco smoking catheter replacement device disclosed in Patent Document 2 to the smokeless tobacco of Patent Document 1. The replacement device comprises: an annular slide which slides on the outer circumferential surface of the pipe body in the axial direction and the circumferential direction of the pipe body; and the snap protrusion and the buckle groove are coupled to each other in a detachable manner The box inside the block and the tube.

According to this replacement device, when the slider slides on the tubular body in the axial direction, the slider pulls the end of the cassette from the tubular body. In this state, as long as the slider slides toward the circumference of the pipe body, the combination of the engaging projection and the snap groove is released. After opening, the slider is returned to its original position, thereby exposing the end of the cassette to the tube body. Therefore, the user can hold the exposed end of the cassette and completely remove the cassette from the tube.

Further, the smokeless tobacco of Patent Document 1 may be provided with a cap covering the nozzle, and an example of the cover is disclosed, for example, in Patent Document 3.

When the replacement device of Patent Document 2 is applied to the smokeless tobacco of Patent Document 1, since the aroma is generated in a free state when the aroma is completely extracted from the pipe body, the user is in a free state according to the posture of the pipe body. Before the aroma is generated, the aroma will fall into the tube or fall out of the tube, and there is no guarantee that the replacement of the aroma will be correct and stable.

Further, the joint structure composed of the engaging projection and the engaging groove does not completely eliminate the sway of the aroma generated sputum relative to the slider, and the aroma generation enthalpy cannot be stably held in the tubular body.

Furthermore, when the aroma is generated, the user must directly hold the aroma to produce a flaw.

The object of the present invention is to provide an aroma suction pipe which can stably hold the aroma generating cockroaches in the pipe body, and the user can pull out the aroma from the pipe body to generate cockroaches without directly holding the scent of the scent. Replacement of aroma The hygiene of the nozzle can be maintained during oysters.

The above object is achieved by the aroma suction pipe of the present invention, the aroma suction pipe system comprising: a pipe body, formed into a tubular shape, and having an open front end and a base end; the cylindrical aroma is generated in a manner capable of being pulled out The inside of the tube is filled with an aroma generating material that volatilizes the aroma component, and allows air to flow from the front end side toward the proximal end side of the tube body; the hollow nozzle is detachably coupled to the tube. The aroma of the end side of the body base generates a crotch end portion, and has a protruding portion protruding from the base end of the pipe body and a front end portion positioned in the pipe body; and a coupling device for detachably joining the base end of the pipe body and the suction nozzle The front end portion has a joint position, and the suction nozzle is elastically urged relative to the pipe body at a predetermined spring force in a direction in which the front end portion of the nozzle emerges from the base end of the pipe body, and the pipe body and the suction nozzle are coupled to each other. And the release position, the nozzle and the elastic thrust are pressed against the tube body, and then the front end of the nozzle is allowed to be pulled out from the tube body when the nozzle is rotated relative to the tube body.

Preferably, the aroma suction pipe is provided with: a cover having an open end and detachably covering the protruding portion of the suction nozzle; and a snapping device, the cover covering the nozzle, the cover and the nozzle are facing The circumferential direction of the cover is engaged with each other. Specifically, the engaging device includes a plurality of ribs projecting from the inner surface of the cover for clamping the end of the nozzle.

In another aspect, the bonding device includes: a flange formed on the outer circumferential surface of the nozzle; a circumferential groove formed on the inner circumferential surface of the base end of the tubular body, and opening at the base end toward the suction nozzle And providing a step surface facing the base end side on the inner circumferential surface of the pipe body; the elastic member is sandwiched between the flange and the step surface, The guide groove is formed on the inner circumferential surface of the pipe body and is open at the step surface, and has an axial direction portion extending from the step surface toward the axial direction of the pipe body; The end of the axial direction portion extends toward the circumferential direction of the tubular body; and the locking claw is disposed on the outer circumferential surface of the front end portion of the suction nozzle, and is located in the circumferential direction portion of the guiding groove and the suction nozzle is subjected to the elastic thrust, thereby utilizing The groove wall in the circumferential direction portion of the guide groove that determines the joint position abuts.

Preferably, in the elastic member, an elastic ring surrounding the outer peripheral surface of the nozzle can be used, and more specifically, an O-ring can be used, and the cross-sectional shape of the O-ring is not limited to a circular shape.

According to the above-described aroma suction pipe, when the coupling device is at the joint position, the engaging claw of the suction nozzle is subjected to the elastic force of the elastic member, and is in a state of being pressed against the groove wall of the circumferential portion of the guide groove. Therefore, the nozzle is stably coupled to the tubular body.

When the aroma suction pipe is provided with a cover, before using the aroma suction pipe, the user first pulls the cover straight out of the suction nozzle to remove the suction nozzle. At this time, since the bonding device is located at the bonding position where the suction nozzle is coupled to the pipe body, the suction nozzle is not pulled out from the pipe body together with the aroma generation.

Thereafter, the user can draw with the exposed nozzle. In the suction, the aroma components volatilized from the aroma generating material in the aroma generating sputum are introduced into the oral cavity of the user together with the air, and as a result, the user can enjoy the aroma component.

When the aroma is generated to reach the limit of use, and the scent is generated to be replaced with a new aroma, the user holds the cover, or straight The state in which the suction nozzle is held is pressed, and the suction force is temporarily pressed against the nozzle body. Here, the press-in is released from the groove wall of the guide groove. In this state, the user only needs to rotate the nozzle toward the circumferential direction of the tubular body, and the locking claw is partially moved from the circumferential direction of the guiding groove toward the axial direction, and the coupling device is positioned at the releasing position from the coupling position. Therefore, in this release position, the user can pull the suction nozzle in the direction of the ejection directly or through the cover, and the locking claw will fall out from the guide groove while partially moving along the axial direction of the guide groove. That is, the nozzle is not obstructed by the snap claws, and is pulled out from the tube together with the aroma generating ridge, and as a result, the aroma is completely extracted from the tube body.

The extracted aroma produces a tether that is removed from the nozzle and a new aroma is applied to the nozzle to create a flaw. Thereafter, the user holds the nozzle directly or through the cover, and inserts a new aroma generating cymbal into the tube body, and inserts the front end of the nozzle into the tube body. The insertion of the nozzle is such that the elastic member, that is, the elastic ring or the O-ring is compressed between the flange of the nozzle and the step surface of the tube body, and the locking claw is partially moved along the axial direction of the guiding groove. Thereby, the bonding device is positioned in the release position.

In this state, the user simply moves the suction nozzle toward the circumferential direction of the tubular body, and the locking claw moves partially along the circumferential direction of the guiding groove. Thereafter, when the user releases the suction of the suction nozzle, the suction nozzle is subjected to the elastic force of the elastic ring or the O-ring, and the locking claw abuts against the groove wall of the circumferential portion of the guiding groove. At this point, the bonding device is positioned at the bonding position and then the replacement of the aroma generating sputum is completed.

According to the aroma suction pipe of the present invention, the bonding device is located at the bonding position At the same time, since the nozzle is elastically coupled to the tube body, the nozzle does not sway relative to the tube body, and the stable coupling of the nozzle to the tube body can be ensured.

On the other hand, when the aroma is changed, the user can pull the aroma generation sputum out of the tube together with the nozzle while holding the nozzle, and the scent can be easily extracted. At this time, as long as the cover covers the nozzle, the user's finger does not directly contact the nozzle, and the aroma generation can be hygienically replaced.

Other features and advantages of the invention will be apparent from the description and appended claims.

Referring to Fig. 1 and Fig. 2, the aroma suction pipe of one embodiment is provided with a tubular pipe body 10 which is formed of synthetic resin and has open ends. In the case of this embodiment, as can be seen from Fig. 3, the cross section of the pipe body 10 does not have a circular profile but has a square-like shape. In detail, the profile of the cross section is formed by four large circular arc faces 10a similar to the flat faces, and four small circular arc faces 10b connecting the arcuate faces 10a, as shown in FIG. As shown, these arcuate faces 10b form four strips 11 on the outer peripheral surface of the pipe body 10. These strips 11 extend in the axial direction of the tubular body 10 and are disposed at intervals of 90° around the axis of the tubular body 10.

As shown in Fig. 2, a cylindrical tobacco crucible 12 is concentrically accommodated in the tubular body 10 as an aroma generating crucible, and the tobacco crucible 12 is movable in the axial direction and the circumferential direction in the tubular body 10.

The tobacco crucible 12 has a tube 14 and is lined at both ends of the tube 14 Do not insert end pieces 16, 18 into it. The end pieces 16, 18 are in the shape of a hollow sleeve and include projecting ends 16a, 18a projecting from the front end and the base end of the tube 14. The protruding ends 16a and 18a have a stepped shape, and have a flange-shaped large diameter portion that is in contact with the end surface on the corresponding side of the tube 14, and a small diameter portion that extends from the large diameter portion. The outer diameter of the large diameter portion is substantially equal to the outer diameter of the tube 14, and the outer diameter of the small diameter portion is smaller than the outer diameter of the tube 14.

Further, an annular projection 20 is integrally protruded from the inner peripheral surface of the front end of the tubular body 10, and the annular projection 20 is provided with an insertion hole 22 at the front end of the tubular body 10. The inner diameter of the insertion hole 22 is slightly larger than the outer diameter of the small diameter portion of the protruding end 16a. Therefore, as shown in Fig. 2, the small diameter portion of the protruding end 16a is inserted into the insertion hole in an extractable manner. 22 inside. Here, it should be noted that a predetermined gap G is secured between the large diameter portion of the protruding end 16a and the annular projection 20.

Further, although the tube 14 and the terminal members 16 and 18 described above are formed of synthetic resin, it is preferable that the tube 14 is transparent or translucent.

Further, cylindrical filters 24 and 26 are disposed adjacent to the end members 16 and 18 in the tube 14, and the filters 24 include acetate fibers and coated with the fibers. The bundle of materials. A filling chamber is formed in the tube 14 between the filters 24, 26, and the filling chamber is filled with the tobacco material T at a predetermined density. The cigarette material comprises cut tobacco and a flavor added to the cut tobacco.

A plurality of ribs 28 are integrally formed on the inner circumference of the tube 14. These ribs 28 extend between the filters 24, 26 in the direction of the axis of the tube 14, from As can be seen from Fig. 4, the tubes 14 are arranged at intervals in the circumferential direction. Such ribs 28 maintain both the strength of the tube 14 and the thinning of the tube 14, and also serve as a stopper for the filters 24, 26.

A predetermined distance is secured between the projecting end 18a of the terminal member 18 and the base end of the tubular body 10, and a hollow nozzle 30 is detachably attached to the small-diameter portion of the projecting end 18a.

More specifically, as can be seen from Fig. 2, the hollow nozzle 30 is formed of a synthetic resin, and includes a cylindrical large-diameter portion 30a and a taper from the protruding end 18a side of the terminal member 18 in this order. The portion 30b and the flat stem portion 30c. The rod portion 30c has a rectangular arch portion 30d at its side end, and the arch portion 30d is larger than the rod portion 30c and has a pair of flat surfaces 30e parallel to each other. The large diameter portion 30a of the suction nozzle 30 is inserted into the base end of the tubular body 10 in a pullable manner, and on the other hand, the small diameter portion of the protruding end 18a is detachably inserted into the large diameter of the suction nozzle 30. In the part 30a. As a result, the flange of the end piece 18 is in a state of being sandwiched between the large diameter portion 30a of the suction nozzle 30 and the tube 14. That is, the large diameter portion 30a of the suction nozzle 30 has an outer diameter slightly smaller than the inner diameter of the tubular body 10, and has an inner diameter slightly larger than the outer diameter of the small diameter portion of the protruding end 18a.

One portion of the large diameter portion 30a, the tapered portion 30b, and the rod portion 30c protrude from the base end of the tubular body 10, and the protruding portion of the suction nozzle 30 is covered by the cover 32 of synthetic resin. The cover 32 has a hollow cylindrical shape with an open end and a closed end.

More specifically, the open end of the cover 32 has an inner diameter slightly larger than the outer diameter of the large diameter portion 30a of the suction nozzle 30. Therefore, the cover 32 is attached to the interior thereof The opening end side receives the protruding portion of the suction nozzle 30, and the opening end is fitted to the large diameter portion 30a from the outside, thereby being detachably coupled to the suction nozzle 30.

The outline of the cross section of the cover 32 has the same size and shape as the outline of the cross section of the tube body 10 described above. Therefore, as shown in Fig. 1, the cover 32 has an outer peripheral surface having 4 corresponding to the aforementioned strip 11 Strips 13.

The open end of the cover 32 has a plurality of engaging recesses 34 on its inner surface, and the engaging recesses 34 are disposed at equal intervals in the circumferential direction of the cover 32. On the other hand, the large-diameter portion 30a of the suction nozzle 30 has engagement projections 36 on the outer circumferential surface thereof with respect to the respective engagement recesses 34, and the engagement projections 36 are also equally spaced in the circumferential direction of the suction nozzle 30. Configuration. Therefore, the cover 32 covers the protruding portion of the suction nozzle 30, and when the engaging projection 36 corresponding to the engaging recess 34 is fitted, the cover 32 is detachably coupled to the suction nozzle 30. The engagement of the engaging recessed portion 34 with the engaging projection 36 serves to prevent the cover 32 from being unintentionally detached from the suction nozzle 30, and is provided for the user to grasp so that the cover 32 normally covers the suction nozzle 30.

Further, four ribs 38 are formed on the inner peripheral surface of the cover 32 on the closed end side of the cover 32. These ribs 38 extend in the axial direction of the cover 32 and are disposed at intervals in the circumferential direction of the cover 32.

In detail, as can be seen from Fig. 5, when the cover 32 normally covers the suction nozzle 30, the four ribs 38 clamp the arched portion 30d of the suction nozzle 30. Specifically, the two ribs 38 are in contact with one of the flat surfaces 30e of the arched portion 30d, and the remaining two ribs 38 are in contact with the other flat surface 30e of the arched portion 30d. In addition, Fig. 5 shows that the four ribs 38 can be clamped not only in the first posture, but also from the first posture to the arched portion 30d, that is, in the nozzle. The second posture shown by the two-point chain line of about 90° is rotated by 30, and the arched portion 30d can be clamped.

The cap 32 and the suction nozzle 30 are coupled to each other in the circumferential direction regardless of the posture of the arch portion 30d by the above-mentioned rib 38 clamping the arch portion 30d. On the other hand, as can be seen from Fig. 1, The strips 13 of the cover 32 and the strips 11 of the corresponding tubular body 10 are integrated with each other on the same line. That is, when the cover 32 is normally covered by the suction nozzle 30, the strips 13 of the cover 32 are positioned in the circumferential direction of the tubular body 10 and the cover 32 at the corresponding strips 11 of the tubular body 10.

On the other hand, the large diameter portion 30a of the suction nozzle 30 is bonded not only to the end piece 18 of the tobacco crucible 12 but also to the base end of the tubular body 10 in a detachable manner by the joining device 40.

The bonding device 40 is as shown in detail in Figures 6 and 7, and the bonding device 40 will be described below.

As shown in Fig. 6(A), the base end of the tubular body 10 has a circumferential groove 42 on its inner peripheral surface. The circumferential groove 42 is opened at the base end surface of the pipe body 10, and on the other hand, an annular stopper surface 44 is formed on the inner circumferential surface of the pipe body 10.

On the other hand, the large diameter portion 30a of the suction nozzle 30 is integrally formed with a flange 46 on the outer circumferential surface thereof, and the flange 46 is positioned closer to the proximal end side of the tubular body 10 than the engagement projection 36. When the cover 32 is normally covered by the suction nozzle 30, the engaging projection 36 is fitted into the engagement recess 34 in a state where the end surface of the cover 32 abuts against the flange 46. That is, the flange 46 functions as a stopper for the cover 32 to determine the axial position of the cover 32 with respect to the suction nozzle 30. In addition, when the cover 32 is normally covered, it can be seen from Fig. 2 that care should be taken between the inner surface of the closed end of the cover 32 and the end of the nozzle 30. The predetermined interval has been secured.

Further, the flange 46 has an outer diameter slightly smaller than the inner diameter of the circumferential groove 42, and therefore, as can be seen from Fig. 6(A), the flange 46 is partially in the state of entering the circumferential groove 42.

Further, an annular elastic member, a so-called O-ring 48, is attached to the outer peripheral surface of the large-diameter portion 30a of the suction nozzle 30. The O-ring 48 is interposed between the end surface of the flange 46 on the opposite side of the engaging projection 36 and the stopper surface 44 of the circumferential groove 42. In detail, the O-ring 48 has an outer diameter smaller than the inner diameter of the circumferential groove 42, and the width D ₀ in the free state is, for example, the same as the width of the circumferential groove 42. Therefore, as described above, when the flange 46 partially enters the circumferential groove 42, the O-ring 48 is in a state of being compressed between the flange 46 and the stopper surface 44 toward the axis of the suction nozzle 30, and the O-ring at this time. The width D _{1 of} 48 is known from Fig. 6(B) to be smaller than the aforementioned width D ₀ .

When the O-ring 48 is in the above-described compressed state, the O-ring 48 pushes the suction nozzle 30 toward the base end of the tubular body 10, but the suction nozzle 30 is dislodged by the nozzle 30. The manner in which the suction nozzle 30 is snapped to the tubular body 10 is blocked.

In detail, the large diameter portion 30a of the suction nozzle 30 has one or more locking claws 50 on its outer peripheral surface, and in the case of this embodiment, there are two locking claws 50. These latching claws 50 are separated from each other in the diameter direction of the suction nozzle 30, and are positioned closer to the front end side than the large diameter portion 30a of the O-ring 48.

On the other hand, two guide grooves 52 are formed on the inner peripheral surface of the pipe body 10, and the guide grooves 52 are separated from each other in the radial direction of the pipe body 10 to receive the corresponding snap claws 50. Each of the guide grooves 52 has a socket facing the front end side of the pipe body 10, and the snap claws 50 abut against the predetermined thrust This seat. The thrust here is obtained by the aforementioned spring force of the nozzle 30, that is, the restoring force of the O-ring 48 due to the compression of the O-ring 48.

As described above, as long as the locking claw 50 is pressed against the socket of the guide groove 52, the suction nozzle 30 is surely coupled to the base end of the tubular body 10, and the suction nozzle 30 does not fall off from the tubular body 10 together with the cover 32.

The shape of the above-described guide groove 52 will be described in detail below.

As can be seen from Fig. 6(B) and Fig. 7, the guide groove 52 has an axial direction portion 52a extending in the axial direction of the tubular body 10 and opening the stopper surface 44 of the circumferential groove 42, and the connection. The circumferential direction portion 52b of the inner end of the axial direction portion 52a. The circumferential direction portion 52b extends from the inner end of the axial direction portion 52a by a predetermined length in the circumferential direction of the tubular body 10.

Preferably, among the two groove walls forming the axial direction portion 52a, at least the groove wall opposed to the end surface of the circumferential direction portion 52b is not parallel to the axis of the pipe body 10, but is attached to the circumferential direction portion 52b. The direction of extension is inclined.

Further, among the two groove walls forming the circumferential direction portion 52b, the above-described socket is provided on the groove wall on the side of the stopper surface 44. In detail, a recess is formed in the groove wall, and the recess cooperates with the end surface of the circumferential portion 52b to form a concave claw seat 54 that allows the insertion of the snap claw 50. Therefore, when the locking claw 50 is embedded in the claw seat 54 (the joint position of the coupling device 40), the claw seat 54 is bounded from the three-way locking claw 50 to prevent the locking claw 50 from moving in the direction of coming out of the tube body 10. And the locking claw 50 moves toward the circumferential direction of the pipe body 10. As a result, not only the sway of the suction nozzle 30 in the axial direction of the pipe body 10 but also the swaying in the circumferential direction of the pipe body 10 is prevented.

When the user uses the aroma suction pipe of the above embodiment, first, use The cover 32 is pulled straight from the suction nozzle 30 toward the axis of the suction nozzle 30, and the engagement between the engagement recess 34 of the cover 32 and the engagement projection 36 of the suction nozzle 30 is released, and then, if further continues When the lid 32 is pulled open, as shown in Fig. 8, the lid 32 is removed from the suction nozzle 30, and the suction nozzle 30 is exposed.

Further, when the cover 32 is pulled away from the suction nozzle 30, since the locking claw 50 of the suction nozzle 30 is fitted into the claw seat 54 of the guide groove 52, that is, the state in which the tubular body 10 is engaged, the suction nozzle 30 does not It will come out of the tube 10 together with the tobacco crucible 12.

In this state, the user holds the arched portion 30d of the nozzle 30 horizontally and sucks through the nozzle 30, thereby enjoying the original flavor and taste of the tobacco in the tobacco crucible 12, and adding it to The aroma of the spice of cut tobacco. In detail, since the tobacco crucible 12 is filled with shredded tobacco and aroma components volatilized from the fragrance, the user's suction is generated from the front end of the tubular body 10 through the tobacco crucible 12 and the suction nozzle 30 to the user's mouth. Air flow. Therefore, the aroma component is guided to the oral cavity of the user together with the air flow, and as a result, the user can enjoy the aroma component without igniting the tobacco.

Further, at the time of suction, the user sandwiches the upper and lower circular arc faces 10a of the tubular body 10 between the index finger and the middle finger, so that the tubular body 10 can be stably held.

On the other hand, when the tobacco crucible 12 reaches the use limit, as shown in Fig. 9, the user can remove the tobacco crucible 12 from the tube body 10 together with the lid 32 and the suction nozzle 30.

Regarding the removal of the tobacco crucible 12 here, it will be described in detail below with reference to FIG.

First, when the aroma suction pipe is in the non-use state shown in Fig. 1, the user places the cover 32 in the direction of the arrow F in Fig. 10(A), that is, Push in towards the tube body 10. At this time, the front end of the cover 32 is in contact with the flange 46 of the suction nozzle 30, and further, the front end of the suction nozzle 30 is in a state of abutting against the flange 46 of the end piece 18 of the tobacco crucible 12, so that the cover 32 is pushed in. The suction nozzle 30 and the tobacco crucible 12 are moved toward the axial direction of the front end side of the tubular body 10. Further, as described above, the movement of the tobacco sheet 12 is ensured by the gap G between the flange of the end piece 16 in the tobacco sheet 12 and the annular projection 20 of the tube body 10 (refer to Fig. 2). It is allowed.

The movement of the suction nozzle 30 described above, as shown in Fig. 10(A), causes the locking claw 50 to be pulled out from the claw seat 54 of the guide groove 52, and on the other hand, the flange 46 of the suction nozzle 30 and the tube body. The O-ring 48 between the stop faces 44 of 10 is more compressed, and the width of the O-ring 48 is further reduced from D ₁ to D ₂ .

Thereafter, as long as the user maintains the push-in of the cover 32 described above, the cover 32 can be rotated about the axis thereof in the direction of the arrow C in FIG. 10(B) (counterclockwise viewed from FIG. 7). As described above, the cover 32 and the suction nozzle 30 are integrally joined in the circumferential direction by the aforementioned ribs 38, so that the suction nozzle 30 and the tobacco rod 12 also rotate together with the cover 32. The rotation of the suction nozzle 30 here causes the locking claw 50 to move from the circumferential direction portion 52b of the guide groove 52 to the axial direction portion 52a (the release position of the coupling device 40).

In this state, as long as the user releases the pressing of the cover 32, the restoring force of the O-ring 48 in the compressed state pushes the suction nozzle 30 back in the direction in which it is ejected from the tubular body 10. Therefore, the width of the O-ring 48 is returned from D ₂ to D ₀ , and on the other hand, the locking claw 50 is moved to the opening end side of the guide groove 52 along the axial direction portion 52a of the guide groove 52.

From this state, the user pulls the cover 32 back in the direction of the arrow R in FIG. 10(C) while holding the cover 32, whereby the locking claw 50 can be pulled out from the guide groove 52, and can be pulled from the tube. The body 10 pulls out the tobacco crucible 12 together with the suction nozzle 30. As a result, as shown in Fig. 9, the tobacco crucible 12 is easily removed from the tubular body 10.

Thereafter, the tobacco crucible 12 is separated from the suction nozzle 30, and the end piece 18 of the new tobacco crucible 12 is inserted into the suction nozzle 30, whereby the new tobacco crucible 12 is bonded to the suction nozzle 30.

The user inserts a new tobacco sheet 12 into the tube body 10 while holding the lid 32, and positions the locking claw 50 of the nozzle 30 at the open end of the corresponding guide groove 52 of the tube body 10. Next (refer to Fig. 7), the large diameter portion 30a of the suction nozzle 30 is pushed into the base end of the tubular body 10, and the locking claw 50 is inserted into the axial direction portion 52a of the guide groove 52. At this time, the O-ring 48 of the suction nozzle 30 is sandwiched between the flange 46 of the suction nozzle 30 and the blocking surface 44 of the pipe body 10, so that the locking claw 50 is positioned in the guiding groove along with the compression of the O-ring 48. The circumferential direction portion 52b of 52 (refer to Fig. 10 (B)).

Thereafter, as long as the user maintains the push-in state of the cover 32 and the suction nozzle 30, the cover 32 is rotated in the clockwise direction, and the cover 32 is integrally coupled with the suction nozzle 30 in the circumferential direction as described above, so that the suction nozzle 30 is provided. And the tobacco crucible 12 also rotates clockwise. Therefore, the locking claw 50 abuts against the end surface of the circumferential direction portion 52b (refer to FIG. 10(A)). In this state, when the user releases the thrust of the cover 32 and the suction nozzle 30, as shown in FIG. As shown in (B), the claws 50 are again fitted into the claw seats 54 of the guide grooves 52, and at this point, the replacement of the tobacco sheets 12 is completed. At this point, the strip 13 of the cover 32 is of course aligned with The strips 11 corresponding to the tube 10 are on the same line.

Further, the replacement of the tobacco crucible 12 may be performed by inserting the new tobacco crucible 12 into the tubular body 10 after inserting the new tobacco crucible 12 into the tubular body 10.

With regard to the replacement of the tobacco crucible 12, since the suction nozzle 30 is held by the cover 32, the user's finger does not directly contact the suction nozzle 30. Therefore, the user can hygienically replace the tobacco crucible 12.
