ABSTRACT OF THE DISCLOSURE
An accumulator type, rechargeable atomizing spray mechanism having a container for the liquid to be atomized, and further having an atomizer body, an atomizer head, an engaging member having a large-diameter hollow cylindrical portion. The atomizer head is arranged to cooperate with skirt-like small-diameter and large-diameter pistons formed at a piston member. The large-diameter hollow cylindrical portion of the engaging member is telescopically inserted within the peripheral wall of the atomizer head and is formed with a rod portion depending from the upper inside portion thereof. Both the pistons are respectively telescopically inserted into the upper large-diameter and lower small-diameter cylindrical portions of the engaging member and the atomizer body. The atomizer body has a longitudinal annular recess formed on the intermediate surface of the cylindrical guide portion thereof and a hole perforated at the connecting portion between the lower cylindrical portion thereof and the cylindrical guide portion thereof. The engaging member has a longitudinal slot perforated at the upper portion of the rod-like valve body thereof. The longitudinal slot operates to communicate the interior of the accumulator chamber with the passage of the suction tube when the valve body reaches its lowermost position to thus exhaust the residual pressure in the accumulator chamber into the liquid suction passage. Thus, the atomizer of this invention can prevent the residual pressure from opacifying the liquid in white in the container.

Description
t~7 3 ~ The present invention relates to an atomizer and, 4 1 more particularly, to an accumu:Lator type atomizer of l manual operation for atomizing a liquid such as perfume, 6 ;i cosmetic preparations or the like.
7 I,l, An accumulator type atomizer of manual operation in 8 ll this specification means an atomizer in which when a pumping 9 I mechanism is manually operated to evacuate the interior '~ of the accumulator chamber of a pump into a vacuum, 11 ~1 a suction valve is opened to intake liquid contained in 12 ! a container mounting an atomizer body thereat into the 13 ~~ accumulator chamber and when the interior of the accumulator 14 ,I chamber is pressurized to become higher than predetermined l pressure, an exhaust valve is merely opened to atomize the 16 l liquid from a nozzle outlet.
17 I Although the atomizer of this type opens its exhaust 18 ~ valve only when the interior of the accumulator chamber 19 ,~ becomes higher than predetermined pressure and closes 1l the exhaust valve automatically when the interior of the 21 ,l accumulator chamber becomes lower than the predetermined 22 jl pressure, it has such a disadvantage that, since high 23 1l pressure lower than the predetermined pressure is residued 24 1l~ in the accumulator chamber, the accumulator chamber is 1~ insufficiently evacuated to a vacuum due to the suction of 26 the liquid caused by the residual pressure. It was proposed, 27 to eliminate tha above described disadvantage, to provide 28 a hole at the upper wall surface of a cylinder forming 29 an accumulator chamber to thereby form a residual pressure ~ exhaust passage communicating with the hole between the I *

7 I,l, An accumulator type atomizer of manual operation in 8 ll this specification means an atomizer in which when a pumping 9 I mechanism is manually operated to evacuate the interior '~ of the accumulator chamber of a pump into a vacuum, 11 ~1 a suction valve is opened to intake liquid contained in 12 ! a container mounting an atomizer body thereat into the 13 ~~ accumulator chamber and when the interior of the accumulator 14 ,I chamber is pressurized to become higher than predetermined l pressure, an exhaust valve is merely opened to atomize the 16 l liquid from a nozzle outlet.
17 I Although the atomizer of this type opens its exhaust 18 ~ valve only when the interior of the accumulator chamber 19 ,~ becomes higher than predetermined pressure and closes 1l the exhaust valve automatically when the interior of the 21 ,l accumulator chamber becomes lower than the predetermined 22 jl pressure, it has such a disadvantage that, since high 23 1l pressure lower than the predetermined pressure is residued 24 1l~ in the accumulator chamber, the accumulator chamber is 1~ insufficiently evacuated to a vacuum due to the suction of 26 the liquid caused by the residual pressure.

!l I
1 ¦ outside surface of the piston or plunger telescoped within
2 jj the cylinder and the inner wall surface of the cylinder
3 1l to thus exhaust the residual pressure when the piston or
4 1l plunger reaches its lowermost limit position. Inasmuch as I the liquid contained in a container of the atomizer is 6 'I exhausted together with the residual pressure in this case 7 ! to cause the exhausted liquid to make contact with the upper 8 ¦ portion of the inner wall of the container to then allow 9 Il the liquid to flow down along the inner wall with the ll result that the liquid thus flown down adheres, in case of 11 , a transparent container, to the upper inside wall to lose 12 l its good appearance due to the liquid seen therethrough.
13Since the exhausted liquid is flown down upon discharge 14 I together with the residual pressure, air bubbles are mixed Ij within the liquid contained in the container to opacity in !l white to thereby look like impurities mixed in the liquid 16 '~
l in the container as an external appearance.
17 ,', 18 li Inasmuch as the large-diameter cylindrical portion 19 Il inserted into the peripheral wall of the atomizer head is ! integrally formed with the engaging member in the conventional 21 '' atomizer, it is complicated to mold and form it.
22 Il~ SUMMARY OF THE INVENTION

28 Another important object of the present invention 29 ll is to provide an accumulator type atomizer of manual operation ~ which can prevent the liquid contained in its container from , :i ~
being exhausted together with the residual pressure and adhered onto the inner wall surface of the container as occurred in the conventional atomizer of this type.
Still another object of the present invention is to provide an accumulator type atomizer of manual operation which can prevent the liquid contained in its container from opacifying in white to thereby eliminate the contamination of its external good appearance.

,I DESCRIPTION OF THE PRE~ERRED EMBODIMENTS
6 l 7 '1' Accumulator type atomizer of manual operation 8 ` constructed according to one preferred embodiment of the 9 1l present invention will now be described with reference 1, to the drawings, particularly to Fig. 1 showing the upper 11 portion of the accumulator type atomizer constructed 12 l according to the present invention, wherein like reference 13 numerals designate the same parts in the following views.
14 l The accumulator type atomizer of the present I invention shown and exemplified in Fig. 1 generally 16 I comprises entirely an atomizer body 1, an atomizer head 17 ll 20, an engaging member 30, a piston member 40, a suction 18 Il tube 50 and a sprlng 60 of six essential members.
19 ! The atomizer body 1 has an engaging peripheral lll wall 2 to be engaged with the neck portion of a container ~, 21 11 body. An internally threaded portion 3 is formed on the 22 ll inner peripheral surface of the wall 2 to be engaged with 23 ll the neck portion of the container. The peripheral wall 24 I 2 is formed integrally with a radially inwardly extending ` flange-like upper wall 4 substantially medially thereof.
26 1 A main cylindrical portion 5 is integrally connected at 27 l the upper outer peripheral surface thereof to the inner 28 ~~ peripheral portion of the flange-like upper wall 4.
29 I The main cylindrical portion 5 has a lower small-diameter ~', hollow cylindrical portion 6 formed at the lower portion l - 5 ~
1.
1 1 thereof, an upper large-diameter hollow cylindrical guide 2 ¦ portion 7 formed at the upper portion thereof, and a suction 3 1 tube engaging hollow cyllndrical. portion 8 integrally 4 1 suspended downwardly from the lower end of the lower i cylindrical portion 6. The cylindrical guide portion 7 6 1 is integrally protruded upwardly at the upper half portion 7 I thereof from the flange-like upper portion 4, and is also 8 ! integrally protruded downwardly at the lower half portion 9 ¦ thereof from the flange-like upper portion 4. A suction li valve hole 9 is perforated at the inside bottom of the 11 I lower cylindrical portion 6. The suction valve hole 9 is 12 ' so formed in the exemplified embodiment in Fig. 1 as to 13 I be perforated at the upper end of a valve hollow cylindrical 14 ll portion 10 stood from the flange-like upper portion 15 'i radially inwardly extended from the lower peripheral end 16 1 of the lower cylindrical portion 6. There are formed 17 1 a longitudinal annular recess 11 on the inner intermediate 18 ¦ surface of the lower portion of the cylindrical guide 19 ~ portion 7, and a hole 12 perforated at the connecting portion between the lower cylindrical portion 6 and the cylindrical guide portion 7.
22 An engaging tubular portion 14 is integrally 23 extended upwardly from the upper intermediate peripheral 24 ¦ portion of the flange-like upper wall 4 with an upper 1 annular inward land 13 formed at the uppermost inside 26 peripheral face thereof for preventing at atomizer head, I
27 1I which will be described in greater detail, from removing 1.
28 ` out therefrom.
29 Ij The atomizer head 20 is made to depend a peripheral 1l wall 22 integrally from the peripheral edge of a top wal.l ~ - 6 -ll l 34~
:, 1 ll 21 thereof and to also form a recess 23 on the top surface 2 1l of the wall 21 for contacting with a finger. The atomizer 3 jl head 20 is in turn formed with a nozzle outlet 24 opened 4 l,~ at the upper side face thereof. The peripheral wall 22 ll of the atomizer head 20 is elevationally movably engaged 6 ,I telescopically with the tubular portion 14 in such a manner 7 Il that the land 13 of the tubular portion 14 is engaged 8 1I with a lower annular outward land 25 formed at the lowermost g ~I outside face of the peripheral wall 22 for preventing the ll atomizer head 20 from removing ou' therefrom.
11 I An engaging member 30 incorporates a large-diameter 12 I hollow cylindrical portion 31 concentrically formed 13 , therewith and telescopically inserted within the peripheral 14 wall 22 of the atomizer head 20 and formed with a rod port-on l 34 depending through a connecting portion 32 form the 16 il upper inside portion thereof, from which portion 34 a rod-like 17 `! valve body 33 depends. The valve body 33 is engaged 18 il with the suction valve hole 9 of the valve cylindrical 19 ll portion 10 to thereby watertightly close the valve hole 9.
11 Thus, the valve body 33 and the valve hole 9 form a suction i 21 ll valve. The lower end of the rod-like valve body 33 is 22 ~I formed with a small-diameter guide extension 35. The cylindrical ~ ~¦ portion 31 is performated with a nozzle opening 36 communicating 24 ll with the nozzle outlet 24. The nozzle opening 36 is normally jl closed by means of a large-diameter piston 43, which will 26 ~l be described in greater detail, and communicates through 27 ~, an exhaust passage 37 perforated at the cylindrical portion 28 11 31 with the nozzle outlet 24.
29 l~ The passage 37 is so constructed in an ordinal way as to spin the liquid passing therethrough.
ll i I !
l 1l A piston member 40 has a tubular portion 41 slidably 2 1~ engaged on the rod portion 34 of the engaging member 30 3 ~ and formed with a skirt-like small-diameter piston 42 at its 4 1 lower end and with a skirt-like large-diameter piston 43 ¦ at its upper end. Both the pistons 43 and 42 are respectively 6 1 telescopically inserted into the upper and lower large-7 diameter and small-diameter cylindrical portions 31 and 6.
8 In the exemplified embodiment shown in Fig. 1, the tubular 9 portion 41 is formed with small diameter at the lower ¦ half portion thereof and with large diameter at the upper ll Ij half portion thereof together with a skirt-like intermediate-12 ,¦ diameter piston 44 formed at the lower end of the upper 13 i¦ half portion thereof. The piston 44 is telescopically inserted j 14 1 into the cylindirical guide portion 7. A gap is formed l between the inner surface of the tubular portion 41 and 16 ', the outer surface of the rod portion 34 to communicate the 17 , small-diameter cylindrical portion 6 with the large-diameter j! cylindrical portion 31.
19 ¦I Suction tube 50 is engaged at the upper end thereof ~¦ with the engaging cylindrical portion 8 in a manner to 21 ~ depend downwardly from the cylindrical portion 8 to such 22 ~ an extent that its lower extremity reaches the bottom wall 23 1 of the container body.
24 1 A coil spring 60 is interposed between the main 1 cylindrical portion 5 of the atomizer body 1 and the 26 'I piston member 40 to always urge the piston member 40, 27 ll the engaging member 30 and the atomizer head 20 upwardly.
28 1i In the exemplifed embodiment in Fig. 1, the coil spring 60 29 i! is interposed between the inside bottom surface of the 1I small-diameter cylindrical portion 6 and the lower end of ~I ~
3~1.21847 ' I
1 l~ the tubular portion 41, but it may not always be interposed 2 ,l as such, and may also be insteacl disposed other than this.
3 1I The spring 60 so urges that the small-diameter piston 4 j! 42 is telescoped to the uppermost end of the small-diameter 1 cylindrical portion 6, the large-diameter piston 43 is 6 1 ¦ telescoped to the uppermost end of the large-diameter 7 1 j cylindrical portion 31 and the intermediate-diameter piston 8 Ij 44 is telescoped to the uppermost end of the cylindrical 9 j, guide portion 7 so that the land 25 formed at the lowermost l¦ outside face of the peripheral wall 22 of the atomizer head ll I 20 is engaged with the upper annular inward land 13 formed 12 l at the uppermost inside peripheral face of the engaging 13 I tubular portion 14. The suction valve formed by the suction 14 I valve hole 9 and the rod-like valve body 33 is opened at ll this time, while an exhaust balve formed by the nozzle 16 opening 36 and the large-diameter piston 43 is closed at 17 , this time.
18 1I The atomizer of the present invention thus constructed 19 ! further incorporates a longitudinal slot 33a perforated at 1 the upper portion of the rod-like valve boddy 33.
21 i The longitudinal slot 33a operates to communicate the interior 22 ,l of the accumulator chamber with the passage of the suction tube 50 as a suction passage therethrough to thereby open 24 `l the suction valve when the valve body 33 reaches its lowermost ' limit position. It is noted that a small-diameter cylindrical 26 portion may also be formed like the aforementioned rod-like 27 i valve body lower end portion instead of the longitudinal 28 slot 33a and that a longitudinal slot may also be perforated 29 ~~ at the lower end portion of the valve body 33 instead of 'I the small-diameter cylindrical portion 35.
i!
I, _ g -l`i !
,1 8~7 , ~ With the atomizer of these construction arrangements, 2 ~¦ when the atomizer is screwed into the neck portion 71 3 ll of a container body 70 filled with liquid and the atomizer 4 ll head 20 is manually depressed against the tension of the ,, spring 60, since the air is filled within an accumulator 6 l~ chamber consisting of the large-diameter cylindrical 7 ~I portion 31, the small-diameter cylindrical portion 6 8 1¦ and the piston member 40, the valve body 33 is slidably 9 ,~ inserted into the suction valve hole 9 to thereby close ''I the suction valve. Then, as the atomizer head 20 is 11 depressed down, the accumulator chamber is gradually 12 ' increased under pressure. Since the piston member 40 is 13 ' thus further telescoped down with respect to the engaging 14 ' member 30 due to the difference of the diameters between I the large-diameter and the small-diameter cylindrical 16 'I portions 31 and 6, the large-diameter piston 43 is telescoped I down in respect of the large-diameter cylinder 31.
17 `ll 18 ll Accordingly, the valve hole 36 is opened with the accumulator 19 l~ chamber to thereby open the exhaust valve so as to exhaust 'I the compressed air through the nozzle outlet 24.
21 `'' When the valve body 33 reaches its lowermost limit position, 22 1I the longitudinal slot 33a communicates the inrerior of the 23 '~ accumulator chamber with the suction tube 50 to exhaust 24 l' the residual pressure to thereby release the high pressure 25 'll state in the accumulator chamber.
26 ~I Thus, the piston member 40 is thus telescoped upwardly with 27 I respect to the engaging member 30 due to the tension of 28 the spring 60 to thereby close the exhaust valve.
29 " When the atomizer head 20 is released from manual depression l~ in this state, the piston member 40, the engaging member "
,1 -- 1 0 ,1 ll;~llB47 l, 30 and the atomizer head 20 are moved upwardly as they are.
2 1I Since the accumulator chamber i.5 evacuated to vacuum or 3 ¦~ negative pressure due to the upward movement of these 4 l¦ members, the suction valve is opened to intake the liquid !I contained in the container body through the suction tube 50.
6 l When the atomizer head 20 is then depressed, compressed 7 liquid is atomized from the nozzle outlet 24. It is noted 8 that the reduction of the liquid in the container should 9 I evacuate to negative pressure in the container, but when the intermediate-diameter piston 44 reaches the annular recess 11 formed on the intermediate inner surface of the cylindrical 12 ~, guide portion 7, a passage is formed between the outer surface 13 '~ of the tubular portion 41 of the piston member 40 and the 14 ~ inner surface of the cylindrical guide portion 7 through ' the annular recess 11 to thereby lnflow the atomspheric air 16 ~l through the hole 12 to thus prevent the negative pressure in 17 'I the container.
18 ll It should be understood from the foregoing description 19 1I that since the atomizer of the present invention is so !¦ constructed as to exhaust the residual pressure in the 21 ~I accumulator chamber into the liquid suction passage upon i 22 ll opening of the suction valve when the rod-like valve body 23 ll reaches its lowermost limit position, it can prevent the 24 ll liquid contained in its container from being exhausted li together with the residual pressure and adhered onto the 26 I inner wall surface of the container as occurred in the 27 ,I conventiona atomizer of this type, and can also prevent 28 ~Ij the liquid contained in its container from opacifying in 29 ll white to thereby eliminate the contamination of its external 30 11 good appearance.
ll l 11'~1847 l ¦l It should also noted that although the atomizer of the 2 present invention has been described with respect to the 3 embodiment of the accumulator type essentially composed 4 of six member, it can also be applied to the other various ~ accumulator type atomizers within the spirits of the present 6 1~ invention.
7 1l Refeering now to fig. 2 showing another preferred 8 !¦ embodiment of the accumulator typ~ atomizer constructed 9 11 according to the present invention, a large-diameter cylinder l¦ 26 is inserted into the peripheral wall 22 of the atomizer ll j head 20, and is perforated with an exhaust valve hole 26b at 12 ~I the center of the top wall 26a thereof.
13 ll An exhaust passage 26c is formed at the upper and 14 ll peripheral surface of the large-diameter cylinder 26 to ll communicate with the nozzle outlet 24 of the atomizer head 20 16 l and with exhaust valve hole 26b in a manner that the passage 17 ~! 26c at the peripheral surface thereof is constructed to spin 18 ~ the liquid passing therethrough.
19 ¦ An engaging member 30a is provided longitudinally at ¦ the center from the large-diameter cylinder 26 to the 21 small-diameter hollow cylindrical portion 6, and incorporates 22 at the top thereof a large-diameter rod portion 31 with 23 a conical valve body 31b projected at the top to form an 24 exhaust valve together with the exhaust valve hole 26b of the large-diameter cylinder 26.

,I DESCRIPTION OF THE PRE~ERRED EMBODIMENTS
6 l 7 '1' Accumulator type atomizer of manual operation 8 ` constructed according to one preferred embodiment of the 9 1l present invention will now be described with reference 1, to the drawings, particularly to Fig. 1 showing the upper 11 portion of the accumulator type atomizer constructed 12 l according to the present invention, wherein like reference 13 numerals designate the same parts in the following views.
14 l The accumulator type atomizer of the present I invention shown and exemplified in Fig. 1 generally 16 I comprises entirely an atomizer body 1, an atomizer head 17 ll 20, an engaging member 30, a piston member 40, a suction 18 Il tube 50 and a sprlng 60 of six essential members.
19 ! The atomizer body 1 has an engaging peripheral lll wall 2 to be engaged with the neck portion of a container ~, 21 11 body. An internally threaded portion 3 is formed on the 22 ll inner peripheral surface of the wall 2 to be engaged with 23 ll the neck portion of the container. The peripheral wall 24 I 2 is formed integrally with a radially inwardly extending ` flange-like upper wall 4 substantially medially thereof.
26 1 A main cylindrical portion 5 is integrally connected at 27 l the upper outer peripheral surface thereof to the inner 28 ~~ peripheral portion of the flange-like upper wall 4.
29 I The main cylindrical portion 5 has a lower small-diameter ~', hollow cylindrical portion 6 formed at the lower portion l - 5 ~
1.
1 1 thereof, an upper large-diameter hollow cylindrical guide 2 ¦ portion 7 formed at the upper portion thereof, and a suction 3 1 tube engaging hollow cyllndrical. portion 8 integrally 4 1 suspended downwardly from the lower end of the lower i cylindrical portion 6. The cylindrical guide portion 7 6 1 is integrally protruded upwardly at the upper half portion 7 I thereof from the flange-like upper portion 4, and is also 8 ! integrally protruded downwardly at the lower half portion 9 ¦ thereof from the flange-like upper portion 4. A suction li valve hole 9 is perforated at the inside bottom of the 11 I lower cylindrical portion 6. The suction valve hole 9 is 12 ' so formed in the exemplified embodiment in Fig. 1 as to 13 I be perforated at the upper end of a valve hollow cylindrical 14 ll portion 10 stood from the flange-like upper portion 15 'i radially inwardly extended from the lower peripheral end 16 1 of the lower cylindrical portion 6. There are formed 17 1 a longitudinal annular recess 11 on the inner intermediate 18 ¦ surface of the lower portion of the cylindrical guide 19 ~ portion 7, and a hole 12 perforated at the connecting portion between the lower cylindrical portion 6 and the cylindrical guide portion 7.
22 An engaging tubular portion 14 is integrally 23 extended upwardly from the upper intermediate peripheral 24 ¦ portion of the flange-like upper wall 4 with an upper 1 annular inward land 13 formed at the uppermost inside 26 peripheral face thereof for preventing at atomizer head, I
27 1I which will be described in greater detail, from removing 1.
28 ` out therefrom.
29 Ij The atomizer head 20 is made to depend a peripheral 1l wall 22 integrally from the peripheral edge of a top wal.l ~ - 6 -ll l 34~
:, 1 ll 21 thereof and to also form a recess 23 on the top surface 2 1l of the wall 21 for contacting with a finger. The atomizer 3 jl head 20 is in turn formed with a nozzle outlet 24 opened 4 l,~ at the upper side face thereof. The peripheral wall 22 ll of the atomizer head 20 is elevationally movably engaged 6 ,I telescopically with the tubular portion 14 in such a manner 7 Il that the land 13 of the tubular portion 14 is engaged 8 1I with a lower annular outward land 25 formed at the lowermost g ~I outside face of the peripheral wall 22 for preventing the ll atomizer head 20 from removing ou' therefrom.
11 I An engaging member 30 incorporates a large-diameter 12 I hollow cylindrical portion 31 concentrically formed 13 , therewith and telescopically inserted within the peripheral 14 wall 22 of the atomizer head 20 and formed with a rod port-on l 34 depending through a connecting portion 32 form the 16 il upper inside portion thereof, from which portion 34 a rod-like 17 `! valve body 33 depends. The valve body 33 is engaged 18 il with the suction valve hole 9 of the valve cylindrical 19 ll portion 10 to thereby watertightly close the valve hole 9.
11 Thus, the valve body 33 and the valve hole 9 form a suction i 21 ll valve. The lower end of the rod-like valve body 33 is 22 ~I formed with a small-diameter guide extension 35. The cylindrical ~ ~¦ portion 31 is performated with a nozzle opening 36 communicating 24 ll with the nozzle outlet 24. The nozzle opening 36 is normally jl closed by means of a large-diameter piston 43, which will 26 ~l be described in greater detail, and communicates through 27 ~, an exhaust passage 37 perforated at the cylindrical portion 28 11 31 with the nozzle outlet 24.
29 l~ The passage 37 is so constructed in an ordinal way as to spin the liquid passing therethrough.
ll i I !
l 1l A piston member 40 has a tubular portion 41 slidably 2 1~ engaged on the rod portion 34 of the engaging member 30 3 ~ and formed with a skirt-like small-diameter piston 42 at its 4 1 lower end and with a skirt-like large-diameter piston 43 ¦ at its upper end. Both the pistons 43 and 42 are respectively 6 1 telescopically inserted into the upper and lower large-7 diameter and small-diameter cylindrical portions 31 and 6.
8 In the exemplified embodiment shown in Fig. 1, the tubular 9 portion 41 is formed with small diameter at the lower ¦ half portion thereof and with large diameter at the upper ll Ij half portion thereof together with a skirt-like intermediate-12 ,¦ diameter piston 44 formed at the lower end of the upper 13 i¦ half portion thereof. The piston 44 is telescopically inserted j 14 1 into the cylindirical guide portion 7. A gap is formed l between the inner surface of the tubular portion 41 and 16 ', the outer surface of the rod portion 34 to communicate the 17 , small-diameter cylindrical portion 6 with the large-diameter j! cylindrical portion 31.
19 ¦I Suction tube 50 is engaged at the upper end thereof ~¦ with the engaging cylindrical portion 8 in a manner to 21 ~ depend downwardly from the cylindrical portion 8 to such 22 ~ an extent that its lower extremity reaches the bottom wall 23 1 of the container body.
24 1 A coil spring 60 is interposed between the main 1 cylindrical portion 5 of the atomizer body 1 and the 26 'I piston member 40 to always urge the piston member 40, 27 ll the engaging member 30 and the atomizer head 20 upwardly.
28 1i In the exemplifed embodiment in Fig. 1, the coil spring 60 29 i! is interposed between the inside bottom surface of the 1I small-diameter cylindrical portion 6 and the lower end of ~I ~
3~1.21847 ' I
1 l~ the tubular portion 41, but it may not always be interposed 2 ,l as such, and may also be insteacl disposed other than this.
3 1I The spring 60 so urges that the small-diameter piston 4 j! 42 is telescoped to the uppermost end of the small-diameter 1 cylindrical portion 6, the large-diameter piston 43 is 6 1 ¦ telescoped to the uppermost end of the large-diameter 7 1 j cylindrical portion 31 and the intermediate-diameter piston 8 Ij 44 is telescoped to the uppermost end of the cylindrical 9 j, guide portion 7 so that the land 25 formed at the lowermost l¦ outside face of the peripheral wall 22 of the atomizer head ll I 20 is engaged with the upper annular inward land 13 formed 12 l at the uppermost inside peripheral face of the engaging 13 I tubular portion 14. The suction valve formed by the suction 14 I valve hole 9 and the rod-like valve body 33 is opened at ll this time, while an exhaust balve formed by the nozzle 16 opening 36 and the large-diameter piston 43 is closed at 17 , this time.
18 1I The atomizer of the present invention thus constructed 19 ! further incorporates a longitudinal slot 33a perforated at 1 the upper portion of the rod-like valve boddy 33.
21 i The longitudinal slot 33a operates to communicate the interior 22 ,l of the accumulator chamber with the passage of the suction tube 50 as a suction passage therethrough to thereby open 24 `l the suction valve when the valve body 33 reaches its lowermost ' limit position. It is noted that a small-diameter cylindrical 26 portion may also be formed like the aforementioned rod-like 27 i valve body lower end portion instead of the longitudinal 28 slot 33a and that a longitudinal slot may also be perforated 29 ~~ at the lower end portion of the valve body 33 instead of 'I the small-diameter cylindrical portion 35.

,1 8~7 , ~ With the atomizer of these construction arrangements, 2 ~¦ when the atomizer is screwed into the neck portion 71 3 ll of a container body 70 filled with liquid and the atomizer 4 ll head 20 is manually depressed against the tension of the ,, spring 60, since the air is filled within an accumulator 6 l~ chamber consisting of the large-diameter cylindrical 7 ~I portion 31, the small-diameter cylindrical portion 6 8 1¦ and the piston member 40, the valve body 33 is slidably 9 ,~ inserted into the suction valve hole 9 to thereby close ''I the suction valve. Then, as the atomizer head 20 is 11 depressed down, the accumulator chamber is gradually 12 ' increased under pressure. Since the piston member 40 is 13 ' thus further telescoped down with respect to the engaging 14 ' member 30 due to the difference of the diameters between I the large-diameter and the small-diameter cylindrical 16 'I portions 31 and 6, the large-diameter piston 43 is telescoped I down in respect of the large-diameter cylinder 31.
17 `ll 18 ll Accordingly, the valve hole 36 is opened with the accumulator 19 l~ chamber to thereby open the exhaust valve so as to exhaust 'I the compressed air through the nozzle outlet 24.
21 `'' When the valve body 33 reaches its lowermost limit position, 22 1I the longitudinal slot 33a communicates the inrerior of the 23 '~ accumulator chamber with the suction tube 50 to exhaust 24 l' the residual pressure to thereby release the high pressure 25 'll state in the accumulator chamber.
26 ~I Thus, the piston member 40 is thus telescoped upwardly with 27 I respect to the engaging member 30 due to the tension of 28 the spring 60 to thereby close the exhaust valve.
29 " When the atomizer head 20 is released from manual depression l~ in this state, the piston member 40, the engaging member "
,1 -- 1 0 ,1 ll;~llB47 l, 30 and the atomizer head 20 are moved upwardly as they are.
2 1I Since the accumulator chamber i.5 evacuated to vacuum or 3 ¦~ negative pressure due to the upward movement of these 4 l¦ members, the suction valve is opened to intake the liquid !I contained in the container body through the suction tube 50.
6 l When the atomizer head 20 is then depressed, compressed 7 liquid is atomized from the nozzle outlet 24. It is noted 8 that the reduction of the liquid in the container should 9 I evacuate to negative pressure in the container, but when the intermediate-diameter piston 44 reaches the annular recess 11 formed on the intermediate inner surface of the cylindrical 12 ~, guide portion 7, a passage is formed between the outer surface 13 '~ of the tubular portion 41 of the piston member 40 and the 14 ~ inner surface of the cylindrical guide portion 7 through ' the annular recess 11 to thereby lnflow the atomspheric air 16 ~l through the hole 12 to thus prevent the negative pressure in 17 'I the container.
18 ll It should be understood from the foregoing description 19 1I that since the atomizer of the present invention is so !¦ constructed as to exhaust the residual pressure in the 21 ~I accumulator chamber into the liquid suction passage upon i 22 ll opening of the suction valve when the rod-like valve body 23 ll reaches its lowermost limit position, it can prevent the 24 ll liquid contained in its container from being exhausted li together with the residual pressure and adhered onto the 26 I inner wall surface of the container as occurred in the 27 ,I conventiona atomizer of this type, and can also prevent 28 ~Ij the liquid contained in its container from opacifying in 29 ll white to thereby eliminate the contamination of its external 30 11 good appearance.
ll l 11'~1847 l ¦l It should also noted that although the atomizer of the 2 present invention has been described with respect to the 3 embodiment of the accumulator type essentially composed 4 of six member, it can also be applied to the other various ~ accumulator type atomizers within the spirits of the present 6 1~ invention.
7 1l Refeering now to fig. 2 showing another preferred 8 !¦ embodiment of the accumulator typ~ atomizer constructed 9 11 according to the present invention, a large-diameter cylinder l¦ 26 is inserted into the peripheral wall 22 of the atomizer ll j head 20, and is perforated with an exhaust valve hole 26b at 12 ~I the center of the top wall 26a thereof.
13 ll An exhaust passage 26c is formed at the upper and 14 ll peripheral surface of the large-diameter cylinder 26 to ll communicate with the nozzle outlet 24 of the atomizer head 20 16 l and with exhaust valve hole 26b in a manner that the passage 17 ~! 26c at the peripheral surface thereof is constructed to spin 18 ~ the liquid passing therethrough.
19 ¦ An engaging member 30a is provided longitudinally at ¦ the center from the large-diameter cylinder 26 to the 21 small-diameter hollow cylindrical portion 6, and incorporates 22 at the top thereof a large-diameter rod portion 31 with 23 a conical valve body 31b projected at the top to form an 24 exhaust valve together with the exhaust valve hole 26b of the large-diameter cylinder 26.
26 ~I The engaging member 30a also incorporates at the 27 1 intermediate portion thereof an intermediate-diameter rod 28 lll portion 32a and at the lower portion thereof a small-diameter 29 ll rod-like valve body 33 to form a suction valve together with ¦¦ the suction valve hole 9 of the valve hollow cylindrical 11;~1847 1 1~ portion 10.
2 ¦ The engaging member 30a further incorporates a fine-3 ¦ diameter guide rod portion 35 at the lowermost portion 4 1, thereof under the valve body 33 to be loosely inserted into 1 the suction valve hole 9.
I A piston member 40a has an upper half tubular portion 7 ~ 41a secured to the outer periphery of the large-diameter 8 I rod portion 31a of the engaging member 30a and formed with 9 Il, an upper skirt-like large-diameter piston 41b slidably ll inserted into the large-diameter cylinder 26 at the upper end of the outer periphery thereof, and a lower half tubular 12 I portion 42a slidably engaged on the outer periphery of the 13 ~¦ intermediate-diameter rod portion 32a of the engaging member 14 11 and formed with an intermediate skirt-like intermediate-I diameter piston 41c slidably inserted into the cylindrical 16 ll guide portion 7.
17 1ll The piston member 40a also has a lower skirt-like 18 1I small-diameter piston 42 slidably inserted into the small-19 ll diameter cylindrical portion 6 at the lower outer periphery ¦ of the lower half tubular portion 42a thereof.
21 llA gap is formed between the inner surface of the 22 ¦tubular portions 41a and 42a and the outer peripheries of 23 `the large-diameter and intermediate-diameter rod portions 24 131a and 32a to communicate the small-diameter cylindrical 25 ll portion 6 with the large-diameter cylinder 26.
26 I Thus, a liquid passage 38 is formed between the outer surface 27 ~l of the engaging member 30 and the inner surface of the 28 I' piston member 40 to communicate the liquid from the container 1.
29 ll body into the passage 37 at the cylindrical portion 31.
30 ¦¦ When the atomizer head 20 is depressed, the liquid is Il- 13 -1~
l introduced through the passage 38 and the passage 37 into 2 the nozzle outlet 24 to atomize the liquid from the outlet 24.
3 The spring 60 so urges that the small-diameter 4 piston 42b is telescoped to the uppermost end of the small-1 diameter cylindrical portion 6, the large-diameter piston 6 1 41b is telescQped to the uppermost piston 41c is telescoped 7 to the uppermost end of the cylindrical guide portion 7 so 8 ¦ that the land 25 formed at the lowermost outside face of 9 ! the peripheral wall 22 of the atomizer head 20 is engaged lO ¦ with the upper annular inward land 13 formed at the ~ uppermost inside peripheral face of the engaging tubular 12 ~¦ and the rod-like valve body 32a is opened at this time, 13 `I while the exhaust valve formed by the exhaust valve hole 26b 14 l¦ and the conical valve body 31b of the large-diameter rod 'll portion 31a of the engaging member is closed at this time.
16 il Since the engaging member 30 and the piston member 40 17 are thus further telescoped down together with the atomizer 18 head 20 with respect to the large-diameter cylinder 26 due l9 to the difference of the diameters between the large-diameter cylinder 26 and the small-diameter cylindrical portion 6, 21 the exhaust valve hole 26b at the top wall 26a of the 22 large-diameter cylinder 26 is opened with the accumulator 23 chamber to thereby open the exhaust valve so as to exhaust 24 ¦ the compressed air through the nozzle outlet 24.
