The holding member is so shaped as to surround the connecting member, thereby to prevent any external force from acting on the flange.
Description
Background of the Invention Field of the Invention The p~esent invention relates to a manually operable a~omizer having an atomlzing means so assoeiated with an atomizing head as to perform a pumping action upon, depres-sion of the atomizing head, thereby to effect an atomization of a liquid through a nozzle.
Description oE the Prior Art In conventional atomiæer of the kind described, the atomizing means have a cylinder provided with a flange ~hich is adapted to be mounted on the opening ridge of a liquid container. For securing the atomi~ing means to the liquid container, the flangç of the cylinder, mounted on the opening ridge of the container, is cramped by a holding sleeve from the outer side thereof.
According to this arrangement, the depression force exerted on the atomizing head, for forcing the atomizing means to perform a pumping action, is received solely by th~ flange. It is therefore preferred that the opening of the liquid container has a small diameter, because a too large diameter of the container opening in relation to the atomizing means renders the support for the atomiæing means unstable, so as to hinder the smooth depressing ~k ' . . :: .: : ~ : .
!3 2(~
operation of the atomizing head. Moreover, the too large diameter of the container opening often causes a leakage of the liquid through the joint area between the atomizing means and the liquid container, during a long use.
For the reasons as stated above, it has been proposed and attempted to make the diameter of the container opening small.
However, this countermeasure cannot be adopted suitably ln such an atomizer as adapted to be used in both of ordlnary and upslde-do~n postures. This is because such an atomizer has a neck portion of a diameter large enough to accommodate two liquid suction pipes, one is for ascending of the liquid while the other is for descending of the same, and, accordingly, requires a container opening of a diameter large enough to recei~e the fat neck portion, posing the aforementioned problems.
The pumping type atomizers must have a container opening stiff enough to stand up against the large depression force exerted on the atomizing head, in sharp contrast to the aerosol type atomizers. The demand for the safe support of the atomizing head by the container opening is increasing recently.

110092~) Su~ma~y of th~ Invention Ob~ects of the Invention It is therefore a major object of the invention to provide an atomizer having a connecting member consistlng of a double sleeve and dlsposed within the neck opening of the liquid container, the connecting members being adapted to carry the flange of a cylinder formed on the atomizing means, thereby to stably support the atomlzlng means.
It is another ob~ect of the lnvention ~o provide an atomizer having such a holding member, in addition to the above mentioned connecting member, as adapted to support the atomizing means on the neck opening of the liquid container in a stable and detachable manner and, at the same time, ensures good watertight seals between the flange and the connecting member and between the wall of the neck opening of the container and the connecting member.
It is still another object of the invention to provide an atomizer which affords, thanks to the combined use of the connecting member and the holding member, a standardization of the size of the flange on the cylinder of the atomizing means independently of the diameter of the neck opening of the liquid container, so as to allow . . . ~

Figs. 9A and 9B are a sectional view of an essential part of a manually operabla atomizer of a sixth embodiment of the invention and an exploded perspective view of the same essential part.
Des~ription oE the PreEerred Embodiment Referrlng first to~Figs. 1 thru 4 showing a first embodiment of the invention, a container 1 accotnmodatlng the liquid to be atomized i9 made of a metal, and has portions starting from a bottom wall 2, barrel portion 3, shoulder portion 4 and a neck opening portion 5 of a dia-meter smaller than that of the barrel portion 3. The upper end brim 6 of the neck opening portion 5 is curled to have a circular cross-sectlon.
Atomizing means 7 have a lower portion received by the container 1 through the nec~ opening por~ion 5 o the latter, and i5 supported at its upper portion by the neck opening portion 5 of the contai~er 1.
The atomlzing means 7 under description have two pressurizing chambers, one is of a smaller diameter while the other is of a larger di~meter. However, the provision of two pressurizing chambers is not exclusive, and the pressurizing means having only one pressurizing chamber can fairly be used.
.: ~ ; ~ . . :, 9Zo The atomizing means 7 of the described embodiment are provided with a first pressurizing chamber section de~ined by a small-diameter cylinder 8 and a cooperating small diameter piston 9, and a second pressurizing chamber section defined by a large diameter cylinder 10 and a cooperating large diameter piston 11.
The first and the second pressurizing chamber sections communic-ate with each other through a tubular plunger 12, and constitute a pressurizing chamber 13. The arrangement is such that the liquid in the pressurizing chamber 13 is pressurized as the atomizing head 14 is depressed overcoming the force of a spring 15, and the pressurized liquid is atomized from a nozzle 17 provided in the atomizing head 14~ via an atomizing valve 16.
As the atomizing head is released ~rom the depressing force, the pistons 9 and 10 of the small and large diameters are returned to the starting positions by the force of the spring 15.
During this returning stroke of the pistons, the next batch of the liquid sucked up from the container 1 up to the pressurizing chamber 13, through a suction pipe 1~ which leads to the suctior.
port of the pressurizing chamber 13. Since the atomizer of the described embodiment is adapted to be used in both of ordinary posture and upside-down posture, another suction pipe 19 beside the first-mentioned suction pipe 18 is connected to the base ~ ;-portion of the suction pipe 18 through an auxiliary member 20 incorporating a three-way valve. Consequently, the lower portion of the atomizing means 7 is made to have a relatively large diameter, so that the neck opening portion 5 of the container has to have a correspondingly large diameter.

~o~ a A flange 21 is formed at the upper end portion of the small diameter cylinder 8, and is extending laterally from the latter. The flange 21 is adapted to r~st on the upper end of a connectin~ member 22 secured to the neck opening portion 5 of the container.
The connecting member~ has an outer peripheral wall 24 and an inner peripheral wall 23 which are connected to each other through a medium of a connecting flange 25, so that the flange 21 of the atomizing means 7 may be held in a stable manner.
The top surface of the inner peripheral wall 23 con-stitu~es an annular supporting sur~ace which supports the afore-mentioned flange 21 through a medium of an annular packing 26.
The upper portion of the inner peripheral wall 23 is made to have a smaller diameter than the lower portion o~ t~e same. An annular peripheral protrusion 27 is formed on the outer per-ipheral wall of the up~er portion of the inner peripheral wall 23, and is adapted to engage an annular protrusion 35 formed on a later-mentioned holding member 31.
An outwardly extending flange 28 is formed on the upper end portion of the outer peripheral wall 24 of the con-necting member 22. The flange 28 is mounted on the brim 6 of the neck opening portion 5 of the container, through a medium of an annular sealing member 2~.

' ~l~V920 An annular protru~ion 30 formed on the outer peripheral surface of the outer peripheral wall 24 is adapted to engage the neck opening portion 5 Qf the container at a part of the latter just below the brim 6, so as to cooperate with the flange 28 in firmly cramping the brim 6 therebetween, thereby to secure the connecting member 22 to the neck opening portion 5 of the container. The connecting member 22 is made o~ a plastic, so that the outer peripheral wall thereof can slightly be bent around its lower end, so that the connecting member 22 is detachably secured to the neck opening 5.
The 1ange 21 of the atomizing means, held by the upper end of the connecting member 22, is pressed from the upper side thereof by a flange 32 of the aforementioned holding member 31. ~
The holding member 31 has a cylindrical portion 33 ~ :
extending downwardly from the outer end portion of the flange 32. The inner periphery of the cylindrical portion 33 has, from the lower end to the upper end thereof, a support-ing surface 34 adapted to be fitted to the lower portion of the ~ .
inner peripheral wall 21 of the connecting member 20, the aforementioned annular protrusion 35 adapted to engage the annular protrusion 27 of the inner peripheral wall 23, an annular protrusion 36 adapted to be contacted by the annular packing 26 and a bearing surface 37 adapted to bear against the outer peripheral surface of the flange 21 - lQ -., : . -. - ~ . . .. . . .

~o~9~o the large diameter cylinder 10 is adapted to engage a step 40 formed on the inner peripheral surface of the cylindrical portion 38, so as to prevent the large diameter cylinder 10 from dropplng out of the cylindric~l portion 38.
An over cap 4~ ls ormed as necessltated at ~he outer slde of the cylindrical portion 38 of the holding member 31. An annular protrusion 42 ~or engage-ment with the brim 6 of the neck opening 5 of the con-tainer is for~ed on the inner peripheral surface o~ the lower portion of the over cap 41.
The over cap 41 is connected to the flange 32 through an extended flange, such that the lower portlon of the ove~ cap 41 can be spread or expanded outwardly around a fulcrum residing in the connecting area of the over cap with the flange 32, so as to afford an easy engagement and disengagement of the annular protrusion 42 with and from the brim 6. The portions of the over cap 41 corresponding to the nozzle 17 and the manipulat-ing portion of the atomizing head 14 are formed as an window 43 or a recess 44.

The atomizing head 14 is surrounded by a cylindrical case 14a the lower portion of which is adapted to move tlp and down through the space defined by the cylindrical portion 38 of the holding member 31 and the over cap 41.
A linear vertical protrusion 45 is formed on the case 14a of the atomizing head 14, and is adapted to be slidlngly received and guided by a cooperatil~g groove 46 formed in the surface of the over cap 41.
Conse~luently, the atomizing head 14 is never rotated with respect to the over cap 41, even when it is depressed strongly,.thereby to keep the nozzle 17 in alignment with the window 43. Needless to say, it is possible to form the linPar protrusion 45 and the cooperat-ing groove 46 in the over cap 41 and in the case 14a, re-spectively.
At the same time, the metallic material of the container 1 is not exclusive and the latter 1 may be made of a plastic. Further, the stable support for the atomizing means 7 provided by the connecting member 22 and the holding member 31 in combinat1on can be performed also for such an atomiæing means as having only one cylinder associated with a piston.

In the foregoing embodiment, the connecting member 22 and the holding member 31 are held by each other by means of engagement of the annular protrusions 27, 35 and 36. However, this manner of holding by each other is not exclusive, and the connecting member 22 and the holding member 31 may be threaded so that they may be screwed to each other.
In the atomiæer having the described construction, the flange 21 formed on the small diameter cylinder 8 i9 cramped between the connecting member 22 and the holding member 31 through an annular packing 26 and, therefore, is firmly held on the neck opening portion 5 of t'ne con tainer. Consequently, a smooth movement of the atomizing head 14 is ensured when the latter is depressed and" at the same time, the atomizer is relieved from the afore-mentioned troubles.
Namely, since the flange 21 is held by the connecting ~
member 22 disposed at the inside o the neck opening 5 of ~;
: -the container, a stable support of the atomizing means is ~ ;
ensured even by the neck opening 5 of a relatively large diameter. In addition, it is not necessary to make the flange 21 for holding the atomizing means 7 specifically ,,. :
92~) large to meet the large diameter of the neck opening 5.
This considerably contribute to the mass production of the atomizing means.
In addltion, since the connecting member 22 and the holding member 31 are secured to each other by means of the mutual engagement of the annular protrus:lons 27 and 36 or by means of the mutual engagement o:f the fl~nge 21 and the annular protrusion 36, the cramping force Eor cramptng the flange 21 is further enhanced.
A~ the same time, the anmllar protrusion 42 formed at the lower end portion of the over cap 41 engages the brim 6 of the neck opening 5, while the latter is cramped by the flange 28 and the annular protrusion 30 of ehe connecting member 22. Besides that, the supporting surface 34, in addition to the protrusions 35, 36, engages the . ~ -- ~ : inner peripheral wall 23 of the connecting member 22, 50 as to further stabilize the support ~f the ~lange~21.
~: In this case, the mutual engagement of the annular pro~
trusions formed on the connecting member 22 and the : holding member 31 enhances the watertightness of the seals at the portion of the flange 21 where the annular packing 26 is provided and at the portion of the neck ~ ::

opening where the annular sealing member 29 is provided.
The combination of the connecting member 22 and the holding member 31 provides a stable support of the atomizing means 7, even when the diameter of the neck opening 5 of the container is made large enough to receive such a fat atomizing means 7 as having two suction pipes lô~ l9 int&nded for use in both of ordinary and upside-down postures, as is the case of the described embodiment.
In aclditlon, the large dlameter cylinder 10 is slidably -held by the cylindrical portion 38 of the holding member 31. This means that the atomizing means 7 is held in a more stable manner at two portlons thereof, i.e. at an upper portion and at a lower portion thereof.
~: :
It is also to be noted as one of the ma~or - ~ advantages of the invention, th~t the annular protrusion 30 of the connecting member 22 and the annular protrusion 42 of the over cap 41 are w~thdrawn from the brim 6 of ~ ~ the neck openlng 5 of the container, as the over cap 41 ; ~ of the holding member 31 is pulled away from the container ; ;~
1, so as to allow an easy separation of the atomlzing means 7 together with the connecting member 22 and the :

holding member 31 from the container 1.
During thls separation of the atomizing means 7 from the container 1, the outer peripheral wall 24 of the connectin~ member 22 is bent lnwardly around the lower end ~hereof~ while the lower portion of the over cap 41 is bent outwardly around the fulcrum residing ln the extended flange portion.
After removing the atomlzing means 7 from the container 1, the container l is again filled wlth the liquid and then the atomizing means 7 are again pressed into the neck opening 5 of the container 1 to bring the annular protrusion 30, 40 again into engagement with the brim 6, thus completing easily the refilling of the container 1.
At the same time, the container 1, which is a : : .
metallic can~ affords an easy printing or the like on ~ :
the surface thereof. In addition, since the depression of the atomizing head 14 is made in the stable and smooth manner without incurring a misalignment of the window 43 ~:~
with the nozzle 17, becuase the atomizing head 14 Is prevented from rotating thanks to the guiding engagement :~
of the linear protrusion 45 with the guiding groove 46 ~ .

Referring now to Fig. 5 showing a second embodi-ment of the invention, the over cap which is annexed to the holding member 31 for enclosing the atomizing head 14 of the foregoing embodiment is neglected. At the same time, the mutual holding of the connecting member 22 and the holding member 31 is made by means of a sole annular protrusion. More. specifically, an annular groove 50 is ;~
formed in the outer peripheral sur~ace of the inner peripheral wall 23 of the connecting member 22, while an annular protrusion 51 adapted for engaging the annular groove 50 ls formed.on the cylindrical portion 33 of the holding member 31. The holding member 31 further has a flange 52 extending laterally from the upper end thereof.
The arrangement is such that the laterally extending flange 52 cooperates with the brim 6 of the neck opening S of the container in cramping the flange 28 of the~
connecting member 22 therebetween. Other portions or parts than specifically mentioned abo~e are all identical to those of the first embodiment, and are denoted by tke same reference numerals.
Thus, the atomi~er of the second embodiment has a simpler construction than the atomizer of the first : ~ ' - . - , . . .. . .

Description oE the Prior Art In conventional atomiæer of the kind described, the atomizing means have a cylinder provided with a flange ~hich is adapted to be mounted on the opening ridge of a liquid container. For securing the atomi~ing means to the liquid container, the flangç of the cylinder, mounted on the opening ridge of the container, is cramped by a holding sleeve from the outer side thereof.
According to this arrangement, the depression force exerted on the atomizing head, for forcing the atomizing means to perform a pumping action, is received solely by th~ flange. It is therefore preferred that the opening of the liquid container has a small diameter, because a too large diameter of the container opening in relation to the atomizing means renders the support for the atomiæing means unstable, so as to hinder the smooth depressing ~k ' . . :: .: : ~ : .
!3 2(~
operation of the atomizing head. Moreover, the too large diameter of the container opening often causes a leakage of the liquid through the joint area between the atomizing means and the liquid container, during a long use.
For the reasons as stated above, it has been proposed and attempted to make the diameter of the container opening small.
However, this countermeasure cannot be adopted suitably ln such an atomizer as adapted to be used in both of ordlnary and upslde-do~n postures. This is because such an atomizer has a neck portion of a diameter large enough to accommodate two liquid suction pipes, one is for ascending of the liquid while the other is for descending of the same, and, accordingly, requires a container opening of a diameter large enough to recei~e the fat neck portion, posing the aforementioned problems.
The pumping type atomizers must have a container opening stiff enough to stand up against the large depression force exerted on the atomizing head, in sharp contrast to the aerosol type atomizers. The demand for the safe support of the atomizing head by the container opening is increasing recently.

Des~ription oE the PreEerred Embodiment Referrlng first to~Figs. 1 thru 4 showing a first embodiment of the invention, a container 1 accotnmodatlng the liquid to be atomized i9 made of a metal, and has portions starting from a bottom wall 2, barrel portion 3, shoulder portion 4 and a neck opening portion 5 of a dia-meter smaller than that of the barrel portion 3. The upper end brim 6 of the neck opening portion 5 is curled to have a circular cross-sectlon.
Atomizing means 7 have a lower portion received by the container 1 through the nec~ opening por~ion 5 o the latter, and i5 supported at its upper portion by the neck opening portion 5 of the contai~er 1.
The atomlzing means 7 under description have two pressurizing chambers, one is of a smaller diameter while the other is of a larger di~meter. However, the provision of two pressurizing chambers is not exclusive, and the pressurizing means having only one pressurizing chamber can fairly be used.
.: ~ ; ~ . . :, 9Zo The atomizing means 7 of the described embodiment are provided with a first pressurizing chamber section de~ined by a small-diameter cylinder 8 and a cooperating small diameter piston 9, and a second pressurizing chamber section defined by a large diameter cylinder 10 and a cooperating large diameter piston 11.
The first and the second pressurizing chamber sections communic-ate with each other through a tubular plunger 12, and constitute a pressurizing chamber 13. The arrangement is such that the liquid in the pressurizing chamber 13 is pressurized as the atomizing head 14 is depressed overcoming the force of a spring 15, and the pressurized liquid is atomized from a nozzle 17 provided in the atomizing head 14~ via an atomizing valve 16.
As the atomizing head is released ~rom the depressing force, the pistons 9 and 10 of the small and large diameters are returned to the starting positions by the force of the spring 15.
During this returning stroke of the pistons, the next batch of the liquid sucked up from the container 1 up to the pressurizing chamber 13, through a suction pipe 1~ which leads to the suctior.
port of the pressurizing chamber 13. Since the atomizer of the described embodiment is adapted to be used in both of ordinary posture and upside-down posture, another suction pipe 19 beside the first-mentioned suction pipe 18 is connected to the base ~ ;-portion of the suction pipe 18 through an auxiliary member 20 incorporating a three-way valve. Consequently, the lower portion of the atomizing means 7 is made to have a relatively large diameter, so that the neck opening portion 5 of the container has to have a correspondingly large diameter.

~o~ a A flange 21 is formed at the upper end portion of the small diameter cylinder 8, and is extending laterally from the latter. The flange 21 is adapted to r~st on the upper end of a connectin~ member 22 secured to the neck opening portion 5 of the container.
The connecting member~ has an outer peripheral wall 24 and an inner peripheral wall 23 which are connected to each other through a medium of a connecting flange 25, so that the flange 21 of the atomizing means 7 may be held in a stable manner.
The top surface of the inner peripheral wall 23 con-stitu~es an annular supporting sur~ace which supports the afore-mentioned flange 21 through a medium of an annular packing 26.
The upper portion of the inner peripheral wall 23 is made to have a smaller diameter than the lower portion o~ t~e same. An annular peripheral protrusion 27 is formed on the outer per-ipheral wall of the up~er portion of the inner peripheral wall 23, and is adapted to engage an annular protrusion 35 formed on a later-mentioned holding member 31.
An outwardly extending flange 28 is formed on the upper end portion of the outer peripheral wall 24 of the con-necting member 22. The flange 28 is mounted on the brim 6 of the neck opening portion 5 of the container, through a medium of an annular sealing member 2~.

' ~l~V920 An annular protru~ion 30 formed on the outer peripheral surface of the outer peripheral wall 24 is adapted to engage the neck opening portion 5 Qf the container at a part of the latter just below the brim 6, so as to cooperate with the flange 28 in firmly cramping the brim 6 therebetween, thereby to secure the connecting member 22 to the neck opening portion 5 of the container. The connecting member 22 is made o~ a plastic, so that the outer peripheral wall thereof can slightly be bent around its lower end, so that the connecting member 22 is detachably secured to the neck opening 5.
The 1ange 21 of the atomizing means, held by the upper end of the connecting member 22, is pressed from the upper side thereof by a flange 32 of the aforementioned holding member 31. ~
The holding member 31 has a cylindrical portion 33 ~ :

An over cap 4~ ls ormed as necessltated at ~he outer slde of the cylindrical portion 38 of the holding member 31. An annular protrusion 42 ~or engage-ment with the brim 6 of the neck opening 5 of the con-tainer is for~ed on the inner peripheral surface o~ the lower portion of the over cap 41.
The over cap 41 is connected to the flange 32 through an extended flange, such that the lower portlon of the ove~ cap 41 can be spread or expanded outwardly around a fulcrum residing in the connecting area of the over cap with the flange 32, so as to afford an easy engagement and disengagement of the annular protrusion 42 with and from the brim 6. The portions of the over cap 41 corresponding to the nozzle 17 and the manipulat-ing portion of the atomizing head 14 are formed as an window 43 or a recess 44.

The atomizing head 14 is surrounded by a cylindrical case 14a the lower portion of which is adapted to move tlp and down through the space defined by the cylindrical portion 38 of the holding member 31 and the over cap 41.
A linear vertical protrusion 45 is formed on the case 14a of the atomizing head 14, and is adapted to be slidlngly received and guided by a cooperatil~g groove 46 formed in the surface of the over cap 41.
Conse~luently, the atomizing head 14 is never rotated with respect to the over cap 41, even when it is depressed strongly,.thereby to keep the nozzle 17 in alignment with the window 43. Needless to say, it is possible to form the linPar protrusion 45 and the cooperat-ing groove 46 in the over cap 41 and in the case 14a, re-spectively.
At the same time, the metallic material of the container 1 is not exclusive and the latter 1 may be made of a plastic. Further, the stable support for the atomizing means 7 provided by the connecting member 22 and the holding member 31 in combinat1on can be performed also for such an atomiæing means as having only one cylinder associated with a piston.

In the foregoing embodiment, the connecting member 22 and the holding member 31 are held by each other by means of engagement of the annular protrusions 27, 35 and 36. However, this manner of holding by each other is not exclusive, and the connecting member 22 and the holding member 31 may be threaded so that they may be screwed to each other.
In the atomiæer having the described construction, the flange 21 formed on the small diameter cylinder 8 i9 cramped between the connecting member 22 and the holding member 31 through an annular packing 26 and, therefore, is firmly held on the neck opening portion 5 of t'ne con tainer. Consequently, a smooth movement of the atomizing head 14 is ensured when the latter is depressed and" at the same time, the atomizer is relieved from the afore-mentioned troubles.
Namely, since the flange 21 is held by the connecting ~
member 22 disposed at the inside o the neck opening 5 of ~;
: -the container, a stable support of the atomizing means is ~ ;
ensured even by the neck opening 5 of a relatively large diameter. In addition, it is not necessary to make the flange 21 for holding the atomizing means 7 specifically ,,. :
92~) large to meet the large diameter of the neck opening 5.
This considerably contribute to the mass production of the atomizing means.
In addltion, since the connecting member 22 and the holding member 31 are secured to each other by means of the mutual engagement of the annular protrus:lons 27 and 36 or by means of the mutual engagement o:f the fl~nge 21 and the annular protrusion 36, the cramping force Eor cramptng the flange 21 is further enhanced.
A~ the same time, the anmllar protrusion 42 formed at the lower end portion of the over cap 41 engages the brim 6 of the neck opening 5, while the latter is cramped by the flange 28 and the annular protrusion 30 of ehe connecting member 22. Besides that, the supporting surface 34, in addition to the protrusions 35, 36, engages the . ~ -- ~ : inner peripheral wall 23 of the connecting member 22, 50 as to further stabilize the support ~f the ~lange~21.
~: In this case, the mutual engagement of the annular pro~
trusions formed on the connecting member 22 and the : holding member 31 enhances the watertightness of the seals at the portion of the flange 21 where the annular packing 26 is provided and at the portion of the neck ~ ::

opening where the annular sealing member 29 is provided.
The combination of the connecting member 22 and the holding member 31 provides a stable support of the atomizing means 7, even when the diameter of the neck opening 5 of the container is made large enough to receive such a fat atomizing means 7 as having two suction pipes lô~ l9 int&nded for use in both of ordinary and upside-down postures, as is the case of the described embodiment.
In aclditlon, the large dlameter cylinder 10 is slidably -held by the cylindrical portion 38 of the holding member 31. This means that the atomizing means 7 is held in a more stable manner at two portlons thereof, i.e. at an upper portion and at a lower portion thereof.
~: :
It is also to be noted as one of the ma~or - ~ advantages of the invention, th~t the annular protrusion 30 of the connecting member 22 and the annular protrusion 42 of the over cap 41 are w~thdrawn from the brim 6 of ~ ~ the neck openlng 5 of the container, as the over cap 41 ; ~ of the holding member 31 is pulled away from the container ; ;~

holding member 31 from the container 1.
During thls separation of the atomizing means 7 from the container 1, the outer peripheral wall 24 of the connectin~ member 22 is bent lnwardly around the lower end ~hereof~ while the lower portion of the over cap 41 is bent outwardly around the fulcrum residing ln the extended flange portion.
After removing the atomlzing means 7 from the container 1, the container l is again filled wlth the liquid and then the atomizing means 7 are again pressed into the neck opening 5 of the container 1 to bring the annular protrusion 30, 40 again into engagement with the brim 6, thus completing easily the refilling of the container 1.
At the same time, the container 1, which is a : : .
metallic can~ affords an easy printing or the like on ~ :
the surface thereof. In addition, since the depression of the atomizing head 14 is made in the stable and smooth manner without incurring a misalignment of the window 43 ~:~

Referring now to Fig. 5 showing a second embodi-ment of the invention, the over cap which is annexed to the holding member 31 for enclosing the atomizing head 14 of the foregoing embodiment is neglected. At the same time, the mutual holding of the connecting member 22 and the holding member 31 is made by means of a sole annular protrusion. More. specifically, an annular groove 50 is ;~
formed in the outer peripheral sur~ace of the inner peripheral wall 23 of the connecting member 22, while an annular protrusion 51 adapted for engaging the annular groove 50 ls formed.on the cylindrical portion 33 of the holding member 31. The holding member 31 further has a flange 52 extending laterally from the upper end thereof.
The arrangement is such that the laterally extending flange 52 cooperates with the brim 6 of the neck opening S of the container in cramping the flange 28 of the~
connecting member 22 therebetween. Other portions or parts than specifically mentioned abo~e are all identical to those of the first embodiment, and are denoted by tke same reference numerals.

Referring now to Figs. 8A and 8B showing a fifth embodiment of the invention, the container is made of a plastic or the like material and has a threaded neck opening portion 85. The flange 21 of the atomizing mcans 7 ls adapted to be directly mounted on the upper end of the neck opening portion 85 of the contalner. The connect-ing member 86 has a cylindrical portion 87 ad~pted for a screwing engagement with-the neok opening portion 85, a flange 88 adapted to cramp the flange 21, and a holding sleeve 89 adapted to slidingly receive the large diameter cylinder 10 of the atomizing means 7. The holding member 90 adapted to cover the atomizing head 14 and the connect-ing member 86 is provided with an inner peripheral wall 91 and an outer peripheral wall 92. The inner peripheral wall 91 has an annular protrusion 93 adapted for engage-ment with the lower end of the connect~ng member 86~ while the outer peripheral wall 92 has an annular protrusion 95 . .

zo adapted to be received by an annular groove 94 formed in the upper end portion of the container.
A window 96 is formed through the wall of the holding member 90 at an upper portion of the latter confronting the nozzle 17 oE the atomizlng head 14.
At the same time, the port:Lon of the holding metnber 90 corresponding to the manipulating portion of the atomizing head 14 i5 recessed as at 97.
The atomlzing head 14 and the holding member 90 are provided with a linear protrus$on 98 and a cooperating groove 99 for slidingly guiding the llnear protrusion 98~ respectively, as is in the first embodi~
ment. Other portions than speclfically mentioned above are materially identical to those of the first embodiment.
As has been stated before, the atomizing means can have only one cylinder or, alternatively, a small and a large diameter cylinders, as is in the case of the foregoing embodiments.
: In the atomizer having the described construction, the flange 21 of the atomizing means is placed on the neck opening S of the container, and is cramped firmly between the connecting member 86 and the neck opening.

In addition, since the holdlng member 90 is provided at the outside of the connecting member, the holding of the atomizing means is protected against any external force and, accordingly, is kept in good orde~.
This holding is stabilized because the ordinary force does not acts on the 1ange.
For removing the aeomizing means 7 from the container, the annular projection 93 i8 disengaged from the connec~ing member 86 andl further, the annular pro-trusion 9S is forced out of the annular groove 94, as the holding member 90 is pulled, so that the latter is separated from the container. Then, as the connecting member 86 is rotated, the atomiæing means 7 are re=oved from the container together with the connecting member 86, since the large diameter cylinder 10 thereof~is firmly held by the connecting member a6. Consequently,~the refilling of the container wit~ the liquid to be atomized can be carried out in quite an easy manner, without necessitating the disassembling of the constituents.

Other portions than spec~fically mentioned above are materially identical to those of the fifth embodiment.
Consequently, the holding sleeve 100 provldes a stable support for the atomizing means. At the same time, a simple rotation of the holding sleeve 100 will cause an upward movement of the same3 which in turn causes the annular protrusion 95 to be disengaged from the annular ~;
groove 94, so as to allow an easy separatlon of the atomizing means along with the holding sleeve from the container.

79 is engaged by the lower face of the annular protrusion 76, so that the flange 78 may be firmly cramped. Other portions than specifically explained above are materi~lly identical to those of the third embodiment.
Referring now to Figs. 8A and 8B showing a fifth embodiment of the invention, the container is made of a plastic or the like material and has a threaded neck opening portion 85. The flange 21 of the atomizing mcans 7 ls adapted to be directly mounted on the upper end of the neck opening portion 85 of the contalner. The connect-ing member 86 has a cylindrical portion 87 ad~pted for a screwing engagement with-the neok opening portion 85, a flange 88 adapted to cramp the flange 21, and a holding sleeve 89 adapted to slidingly receive the large diameter cylinder 10 of the atomizing means 7. The holding member 90 adapted to cover the atomizing head 14 and the connect-ing member 86 is provided with an inner peripheral wall 91 and an outer peripheral wall 92. The inner peripheral wall 91 has an annular protrusion 93 adapted for engage-ment with the lower end of the connect~ng member 86~ while the outer peripheral wall 92 has an annular protrusion 95 . .
.
zo adapted to be received by an annular groove 94 formed in the upper end portion of the container.
A window 96 is formed through the wall of the holding member 90 at an upper portion of the latter confronting the nozzle 17 oE the atomizlng head 14.
At the same time, the port:Lon of the holding metnber 90 corresponding to the manipulating portion of the atomizing head 14 i5 recessed as at 97.
The atomlzing head 14 and the holding member 90 are provided with a linear protrus$on 98 and a cooperating groove 99 for slidingly guiding the llnear protrusion 98~ respectively, as is in the first embodi~
ment. Other portions than speclfically mentioned above are materially identical to those of the first embodiment.
As has been stated before, the atomizing means can have only one cylinder or, alternatively, a small and a large diameter cylinders, as is in the case of the foregoing embodiments.
: In the atomizer having the described construction, the flange 21 of the atomizing means is placed on the neck opening S of the container, and is cramped firmly between the connecting member 86 and the neck opening.

. . . ~
In addition, since the holdlng member 90 is provided at the outside of the connecting member, the holding of the atomizing means is protected against any external force and, accordingly, is kept in good orde~.
This holding is stabilized because the ordinary force does not acts on the 1ange.
For removing the aeomizing means 7 from the container, the annular projection 93 i8 disengaged from the connec~ing member 86 andl further, the annular pro-trusion 9S is forced out of the annular groove 94, as the holding member 90 is pulled, so that the latter is separated from the container. Then, as the connecting member 86 is rotated, the atomiæing means 7 are re=oved from the container together with the connecting member 86, since the large diameter cylinder 10 thereof~is firmly held by the connecting member a6. Consequently,~the refilling of the container wit~ the liquid to be atomized can be carried out in quite an easy manner, without necessitating the disassembling of the constituents.
- . .
Fig. 9A and Fig. 9B in combination show a sixth embodiment of the invention in which the connecting member 86 and the holding member 90 of the fifth embodiment are . , .

ll~as20 made unitary with each other to form an integral holding sleeve 100 and, accordingly, the annular p~ojection 93, which is used in the fifth embodiment for attaining the mutual engagement of the connecting member and the hold-ing member, is neglected from this sixth embodiment.
Other portions than spec~fically mentioned above are materially identical to those of the fifth embodiment.
Consequently, the holding sleeve 100 provldes a stable support for the atomizing means. At the same time, a simple rotation of the holding sleeve 100 will cause an upward movement of the same3 which in turn causes the annular protrusion 95 to be disengaged from the annular ~;
groove 94, so as to allow an easy separatlon of the atomizing means along with the holding sleeve from the container.
