The auxlllary walls 6 and 6 of Flg. 8, whlch are erected along the righthand and lefthand slde portlons of the top wall of the cap-shaped member, partly provlde a flnger grlp, when the contalner is held at lts upper portlon by the hand, and partly gulde the head 18 when the head ls moved down, to prevent the head from movlng to the rlght and left.
BEST MODE FOR CARRYING OUT THE INVENTION
Flrst of all, the flrst embodlment shown ln Flgs. 1 and 2 wlll be descrlbed ln the followlng. Reference 207~17~
numeral 1 designates a container body having an erect-ed mouth/neck portion 2. On the outer face of the mouth/neck portion, there is screwed the lower half of a circumferential wall 5 which depends from the outer circumference of the top wall of a cap-shaped member 3. Said member is formed with a hole 8 at the central portion of the top wall 4. The upper half of the cir-cumferential wall is radially reduced to have a smal-ler internal diameter than the external diameter of the mouth/neck portion, and the reduced portion has its lower end face mounted through a packing 9 on the upper end face of the mouth/neck portion.
In the upper half of the aforementioned circum-ferential wall 5, there is fitted a short cylinder 12 which is erected from the ~uter circumference of an external flange 11 formed in the upper portion of a cylinder 10. This cylinder 10 has a larger-diameter portion lOa at its upper portion and a smaller-diame-ter portion lOb at its lower portion and is equipped in the inner face of its lower end with a suction valve 13 of a ball valve. A pipe 14 depends to the bottom portion of the container body from the lower end of the cylinder 10. An air vent hole 15 is formed in the aforementioned larger-diameter portion lOa.
From the inside of the aforementioned cylinder 10, there is erected through the aforementioned hole 8 a stem 17 which is equipped with a cylindrical piston 16 at its lower end. On the upper end of said stem, there is fitted a head 18 which has a nozzle 19 opened forward. The cylindrical piston 16 and the stem 17 may be made of different members, as shown. In the shown embodiment, the cylindrical piston has its smal-ler-diameter cylindrical portion 16b erected from the upper end of its cylinder portion 16a through an in-ward flanged portion and fitted in the lower portion of the stem 17. These cylindrical piston 16, stem 17 and head 18 constitute altogether an actuator 20, which is equipped with a discharge valve. This dis-charge valve is formed, in the shown embodiment, by fitting a valve member 21, which has longitudinal grooves in its outer face, vertically movably in the stem 17 so that it is defined by the lower end face of said valve member and the upper end of the bore of the aforementioned smaller-diameter cylinder portion. The valve member 21 is biased downward by a spring 22 which is fitted in the stem. This spring has its up-per end engaging with the lower face of the inward flange formed at the upper end of the stem. On the outer face of the lower portion of the stem 17, there may be fitted a sliding cylinder 25, which has its 2รป7~176 lower portion formed on its outer circumference with a ring-shaped sealing member 26 fitted in the cylinder larger-diameter portlon lOa and which has its lower end engaging with the upper end face of the cylinder portion of the cylindrical piston 16. As shown in Fig. 2, said sliding cylinder is moved down together with the stem 17 by depressing the head 18, until it is stopped when said sealing member has its lower end contacting with the upper end of the cylinder smaller-diameter portion lOb so that the sealing member 26 shuts out the air vent hole 16. However, the stem 17 is further moved down with respect to the sliding cylinder 25. When the stem is to be moved up, on the other hand, the cylindrical piston has its cylinder portion 16a contacting with the lower end of the slid-ing cylinder 25 to push up said slider cylinder. If the container has its inside evacuated as the liquid decreases, the sealing member 26 is moved upward of the air vent hole 15. After this, the ambient air is introduced into the container body through the clear-ance between the inner edge of the hole 8 and the outer face of the sliding cylinder 25, through the clearance which is established between the sealing member 26 and the inner face of the larger-diameter portion of the cylinder by deforming said sealing mem-ber 26 elastically, and through the air vent hole 15.In the shown embodiment, the nozzle opened in the front face of the head is used for atomizations. De-spite of this fact, however, there can be provided a foaming container or a liquid discharge container either, as is well known in the art, by changing the nozzle structure into a foaming one or by making a head for inJecting a liquid as it is. To the upper face of the head 18, there is attached a ring-shaped finger knob 30 which has its ring hole directed for-ward or backward. Said finger knob is sized to admit the finger tip into the ring-shaped portion. Said finger knob 30 has its finger hole 31 opened forward or backward.
Next, the following description is directed to the second embodiment shown in Figs. 3 and 4.
Said embodiment is formed by hinging the righ-thand and lefthand two end portions of a U-shaped bail 30a of the finger knob 30 to the righthand and lef-thand two side faces of the head 18 such that the finger knob 30 can be turned up and down. When the U-shaped bail 30a is erected, the finger hole 31 is formed by the upper face of the head 18 and the inner face of the U-shaped bail 30a. When the U-shaped bail is fallen down forward, it shuts out the front face of 2~517~
the nozzle 19. As shown, the U-shaped bail 30a may preferably be formed at its intermediate portion with an operation pro~ection 32. Moreover, the upper end portion of the front face of the circumferential wall of the cap-shaped member 3 and the U-shaped bail 30a are respectively formed with a pro~ection 33 for lock-ing the U-shaped bail in its forward fallen position and an engagement member 34 for engaging with said pro~ection.
In the third embodiment shown in Figs. 5, 6 and 7, said finger knob 30 is formed of an inverted U-shaped bail 41 which is erected from the righthand and lefthand two sides of a sliding cylinder 40 fitted vertically movably on the outer face of the head 18.
The outer end of the head 18 and the lower end of the sliding cylinder 40 are formed at their respective outer and inner circumferences with first and second engagement ridges 42 and 43. Slightly below the first engagement ridge 42 of the head, as shown in Fig. 7, there may be formed a third engagement ridge 44 which is given such a slightly smaller external diameter than that of the first engagement ridge 42 as to allow the second engagement ridge of the sliding cylinder to forcibly ride thereover. Then, the sliding cylinder 40 can be prevented from automatically moving down, ~7~ 76 " ~
when lt ls pulled up, so long as the lnverted U-shaped ball 41 ls not depressed while leavlng the second engagement rldge 43 posltloned between the thlrd engagement rldge 44 and the flrst engagement rldge 41. In thls embodlment, the discharge valve of the flrst embodlment ls replaced by one whlch ls formed of a ball valve dlsposed ln the upper end portlon of the stem 17.
In the embodlment shown ln Flgs. 8 to 10, auxlllary walls 6 and 6 for actlng as the flnger grlp and guldlng the head are erected from the rlghthand and lefthand two portlons of the top wall 4 of the cap-shaped member 3 of Flg. 1, and a rear wall 7 for connectlng the rear portlons of the lower halves of those auxlllary walls ls erected from the rear portlon of the top wall. In thls embodlment, the head 18 ls formed generally lnto such a square shape that lt can be moved up and down whlle havlng lts rlghthand and lefthand slde faces contactlng wlth the lnner faces of the auxlllary walls 6.
These auxlllary walls 6 and 6 can be added to the respectlve cap-shaped members 3 of the second embodlment shown ln Flgs. 3 and 4 and the thlrd embodlment shown ln Flgs. 5, 6 and 7.
The flnger knob 30 can be concelved to have a - 207~17B
variety of shapes, as showrl at A, ~, C, D and E in ~ig. 11, in addition to those of t~e foregoing embodi.-ments. The finger knob has a shapc Or letter C at A
in ~ig. 11, a shape, in which arcuate members are proJected upward and inward from the righthand and lefthand side faces of the head 18 to have their upper ends ad~acent to each other, at B in ~ig. 11, a shape of inverted l.etter U at C in ~lg. 11, a shape o-f in-verted letter I. a~ D in ~lg. 11, and a sllape of letter T at E in ~lg. 11. In case o~ the finger Icnob of said shape of ~et.ter T, tlle rlsing porti.on may be pinc}Ied and moved up and down by two fingers.
INDIISTRIAL API'LICA13ILITY
With the strlIctllre thus far described, according to the present invention, tlIe sprlng for pushirIg up tlle actuator of tlle liqllld discIIarge contaJner of the aforemeIltioned example Or the prior art is eliminated to make thc force unnecessary -for compressing the spring at the time of depressing the actuator so that the actuator can be depressed by a less force than that of the prior art. Since, moreover, the finger knob is attaclled to the upper face of the head, the actuator can be casily moved up and down by havlng the flnger Isnob hooked by tlle finger tlp of the hand hold-~7~ 7~
,~
lng the contalner.
Because of the absence of the actuator depressingsprlng, still moreover, the actuator can be stopped in its lower posltion, when the container ls not used, so that the contalner can be made lower and more compact than that of the prior art. Since, furthermore, the finger knob 30 is attached to the upper face of the head, the finger on the head can be set ln a constant posltlon so that the posltion of the finger knob on the head can be made proper. As a result, the head can always be depressed substantlally vertlcally unllke the prlor art whlle belng prevented from belng pushed transversely or from the back, so that the llquld can be prevented from leaking otherwlse due to the transverse push or the push from the back.
Moreover, the flnger knob has the U-shaped ball havlng lts two end portlons so hlnged to the righthand and lefthand two side faces of the head that it can stand up to define the finger hole wlth the top face of the head and the lnner face of the U-shaped ball and can fall down to shut out the front face of the nozzle wlth the lnner face of the U-shaped ball. As a result, the nozzle can be kept away from dust or the llke so that it can be prevented from gettlng clogged.
The flnger knob has the inverted U-shaped bail erected from the rlghthand and lefthand two sides of the sliding cyllnder, which is fltted vertically slidably on the outer face of the head. As a result, the upper portlon of the flnger knob can be posltloned, whlle the container ls unused, ~5~ ~6 , ln the vlclnlty of the upper face of the head because the sllding cyllnder ls ln the lower posltlon, thus ralslng an advantage that the overall helght of the contalner can be reduced.
The auxlllary walls actlng as the flnger grlp and gulding the head are so erected from the rlghthand and lefthand two slde portlons of the top wall of the cap-shaped member along the rlghthand and lefthand two slde faces of the head as to allow the vertlcal movements of the head. As a result, the actuator can be operated by gripplng the upper portlon of the contalner body and the lower portlons of the auxlllary walls when the contalner ls held for operatlng the actuator. Thus, the grlp posltion of the hand can be made higher than that of the case of no auxlllary wall, to ralse the flnger tlp engaglng wlth the flnger knob thereby to lncrease the stroke of the actuator. Moreover, the head can be prevented from shaklng by the guldance of the auxili-207~17~
ary walls, while it is being moved up and down, so that the operation of the actuator can be facilitated.

As shown in Fig. 2, said sliding cylinder is moved down together with the stem 17 by depressing the head 18, until it is stopped when said sealing member has its lower end contacting with the upper end of the cylinder smaller-diameter portion lOb so that the sealing member 26 shuts out the air vent hole 16. However, the stem 17 is further moved down with respect to the sliding cylinder 25. When the stem is to be moved up, on the other hand, the cylindrical piston has its cylinder portion 16a contacting with the lower end of the slid-ing cylinder 25 to push up said slider cylinder. If the container has its inside evacuated as the liquid decreases, the sealing member 26 is moved upward of the air vent hole 15. After this, the ambient air is introduced into the container body through the clear-ance between the inner edge of the hole 8 and the outer face of the sliding cylinder 25, through the clearance which is established between the sealing member 26 and the inner face of the larger-diameter portion of the cylinder by deforming said sealing mem-ber 26 elastically, and through the air vent hole 15.In the shown embodiment, the nozzle opened in the front face of the head is used for atomizations. De-spite of this fact, however, there can be provided a foaming container or a liquid discharge container either, as is well known in the art, by changing the nozzle structure into a foaming one or by making a head for inJecting a liquid as it is. To the upper face of the head 18, there is attached a ring-shaped finger knob 30 which has its ring hole directed for-ward or backward. Said finger knob is sized to admit the finger tip into the ring-shaped portion. Said finger knob 30 has its finger hole 31 opened forward or backward.
Next, the following description is directed to the second embodiment shown in Figs. 3 and 4.
Said embodiment is formed by hinging the righ-thand and lefthand two end portions of a U-shaped bail 30a of the finger knob 30 to the righthand and lef-thand two side faces of the head 18 such that the finger knob 30 can be turned up and down. When the U-shaped bail 30a is erected, the finger hole 31 is formed by the upper face of the head 18 and the inner face of the U-shaped bail 30a. When the U-shaped bail is fallen down forward, it shuts out the front face of 2~517~
the nozzle 19. As shown, the U-shaped bail 30a may preferably be formed at its intermediate portion with an operation pro~ection 32. Moreover, the upper end portion of the front face of the circumferential wall of the cap-shaped member 3 and the U-shaped bail 30a are respectively formed with a pro~ection 33 for lock-ing the U-shaped bail in its forward fallen position and an engagement member 34 for engaging with said pro~ection.
In the third embodiment shown in Figs. 5, 6 and 7, said finger knob 30 is formed of an inverted U-shaped bail 41 which is erected from the righthand and lefthand two sides of a sliding cylinder 40 fitted vertically movably on the outer face of the head 18.
The outer end of the head 18 and the lower end of the sliding cylinder 40 are formed at their respective outer and inner circumferences with first and second engagement ridges 42 and 43. Slightly below the first engagement ridge 42 of the head, as shown in Fig. 7, there may be formed a third engagement ridge 44 which is given such a slightly smaller external diameter than that of the first engagement ridge 42 as to allow the second engagement ridge of the sliding cylinder to forcibly ride thereover. Then, the sliding cylinder 40 can be prevented from automatically moving down, ~7~ 76 " ~
when lt ls pulled up, so long as the lnverted U-shaped ball 41 ls not depressed while leavlng the second engagement rldge 43 posltloned between the thlrd engagement rldge 44 and the flrst engagement rldge 41. In thls embodlment, the discharge valve of the flrst embodlment ls replaced by one whlch ls formed of a ball valve dlsposed ln the upper end portlon of the stem 17.
In the embodlment shown ln Flgs. 8 to 10, auxlllary walls 6 and 6 for actlng as the flnger grlp and guldlng the head are erected from the rlghthand and lefthand two portlons of the top wall 4 of the cap-shaped member 3 of Flg. 1, and a rear wall 7 for connectlng the rear portlons of the lower halves of those auxlllary walls ls erected from the rear portlon of the top wall. In thls embodlment, the head 18 ls formed generally lnto such a square shape that lt can be moved up and down whlle havlng lts rlghthand and lefthand slde faces contactlng wlth the lnner faces of the auxlllary walls 6.
These auxlllary walls 6 and 6 can be added to the respectlve cap-shaped members 3 of the second embodlment shown ln Flgs. 3 and 4 and the thlrd embodlment shown ln Flgs. 5, 6 and 7.
The flnger knob 30 can be concelved to have a - 207~17B
variety of shapes, as showrl at A, ~, C, D and E in ~ig. 11, in addition to those of t~e foregoing embodi.-ments. The finger knob has a shapc Or letter C at A
in ~ig. 11, a shape, in which arcuate members are proJected upward and inward from the righthand and lefthand side faces of the head 18 to have their upper ends ad~acent to each other, at B in ~ig. 11, a shape of inverted l.etter U at C in ~lg. 11, a shape o-f in-verted letter I. a~ D in ~lg. 11, and a sllape of letter T at E in ~lg. 11. In case o~ the finger Icnob of said shape of ~et.ter T, tlle rlsing porti.on may be pinc}Ied and moved up and down by two fingers.
INDIISTRIAL API'LICA13ILITY
With the strlIctllre thus far described, according to the present invention, tlIe sprlng for pushirIg up tlle actuator of tlle liqllld discIIarge contaJner of the aforemeIltioned example Or the prior art is eliminated to make thc force unnecessary -for compressing the spring at the time of depressing the actuator so that the actuator can be depressed by a less force than that of the prior art. Since, moreover, the finger knob is attaclled to the upper face of the head, the actuator can be casily moved up and down by havlng the flnger Isnob hooked by tlle finger tlp of the hand hold-~7~ 7~
,~
lng the contalner.
Because of the absence of the actuator depressingsprlng, still moreover, the actuator can be stopped in its lower posltion, when the container ls not used, so that the contalner can be made lower and more compact than that of the prior art. Since, furthermore, the finger knob 30 is attached to the upper face of the head, the finger on the head can be set ln a constant posltlon so that the posltion of the finger knob on the head can be made proper. As a result, the head can always be depressed substantlally vertlcally unllke the prlor art whlle belng prevented from belng pushed transversely or from the back, so that the llquld can be prevented from leaking otherwlse due to the transverse push or the push from the back.
Moreover, the flnger knob has the U-shaped ball havlng lts two end portlons so hlnged to the righthand and lefthand two side faces of the head that it can stand up to define the finger hole wlth the top face of the head and the lnner face of the U-shaped ball and can fall down to shut out the front face of the nozzle wlth the lnner face of the U-shaped ball. As a result, the nozzle can be kept away from dust or the llke so that it can be prevented from gettlng clogged.
The flnger knob has the inverted U-shaped bail erected from the rlghthand and lefthand two sides of the sliding cyllnder, which is fltted vertically slidably on the outer face of the head. As a result, the upper portlon of the flnger knob can be posltloned, whlle the container ls unused, ~5~ ~6 , ln the vlclnlty of the upper face of the head because the sllding cyllnder ls ln the lower posltlon, thus ralslng an advantage that the overall helght of the contalner can be reduced.
The auxlllary walls actlng as the flnger grlp and gulding the head are so erected from the rlghthand and lefthand two slde portlons of the top wall of the cap-shaped member along the rlghthand and lefthand two slde faces of the head as to allow the vertlcal movements of the head. As a result, the actuator can be operated by gripplng the upper portlon of the contalner body and the lower portlons of the auxlllary walls when the contalner ls held for operatlng the actuator. Thus, the grlp posltion of the hand can be made higher than that of the case of no auxlllary wall, to ralse the flnger tlp engaglng wlth the flnger knob thereby to lncrease the stroke of the actuator. Moreover, the head can be prevented from shaklng by the guldance of the auxili-207~17~
ary walls, while it is being moved up and down, so that the operation of the actuator can be facilitated.
