The specific embodiment
Below execute routine accompanying drawing the present invention carried out more detailed elaboration by preferable buying.
As shown in Figure 1, support cap 20 can be by the screw thread mouth neck portion 11 of flask 10 of liquid content that has been fixed on can, and can carry out dismounting at any time.In support cap 20, installed can draw respectively content in the container 10 and extraneous air, the dual-pressure pump 30 of pressurization, force feed.
The cylinder 31 that compression pump 30 has is chimeric with support cap 20 undercutting (undercut), fall in support cap 20 belows, being connected in series by small-bore barrel 31a with small-bore barrel is that the heavy caliber barrel 31b of one forms.Small-bore barrel 31a comprises the introducing port 31h that the pipeline 31p that draws container 10 interior contents is connected.
Small-bore barrel 31a comprises: utilize spring S flexibly to support small-bore barrel 31a and at the piston 32 of small-bore barrel 31a slides within; The chimeric freely poppet valve 33 of dismounting in the passage P1 of this internal piston; And piston leads arm 34, have passage P2 with give as security press this piston 32 and this poppet valve, the top 33b of this poppet valve 33 to be installed on the passage P1 place of piston 32 or from the dismounting of passage P1 place with folding passage P2.The inboard that piston is led the top 34b of arm 34 is provided with the content compression pump exit passageway P3 that utilizes spherical valve to be communicated with the passage P2 that is opened and closed.Finish the drawing of content, pressurization, force feed work by above-mentioned these parts.
What reference number 40 was represented is that cover 40 is pressed in the signature that is equipped with nozzle.Give as security pressing cover 40 is outer periphery of supporting top, the top 35a of air slide 35 slidably, also has simultaneously to be embedded in the barrel 40a that piston is led top, the top 34b of arm 34, thereby makes piston lead arm 34 and air slide 35 for can give as security pressure.In addition, give as security to press cover 40 to converge space R by what aftermentioned bubble generation member 50 formed that the exit passageway P3 of content compression pumps and external air pressure pump discharge passage P4 converge; Give as security and press cover also to have inner passage 42, be communicated with this and converge space R and lead to outside ejection end 41.
The various piece that constitutes bubble generation member 50 is: in be embedded in and give as security the sparge ring 51 of pressing cover 40 barrel 40a inside; Be embedded in 2 grid rings 52 in this sparge ring 51.The various piece that constitutes sparge ring 51 has: thus go into side opening H than what give as security the narrow raising of inner passage 42 bores of pressing cover 40 mixed content thing jet velocity; Opening diameter is gone into side opening H greater than this, and is connected the cylindrical shell 51b of (connection) mutually with inner passage 42.Sparge ring 51 converges space R with the common formation in inboard that piston is led top, the top 34b of arm 34 on every side.Grid ring 52 is made of the grid 52a that has most micro hole, is arranged at cylindrical shell 52b one end of hollow.This grid 52a is installed in the cylindrical shell 51b inside face of sparge ring 51 on the position of going into side opening H.The content that has mixed extraneous air touches on the grid 52a, and a part wherein is by these small holes, and the content that has mixed extraneous air produces foam therefrom.
For this reason, when external force such as finger extruding is given as security when pressing cover 40, in small-bore barrel 31a, top, the below 33a of poppet valve 33 is attached on the introducing port 31h, form and piston 32 between the T1 of cylinder chamber.Content pressurized when piston 32 pressures are come in the T1 of cylinder chamber makes top, the top 33b of poppet valve 33 leave the passage P1 of piston 32.As Fig. 1, shown in the 2 arrow D1, content is extruded thus to exit passageway P3.For this reason, ball valve V (ba11 valve) opens, to converging space R supply content thing.Meanwhile, at heavy caliber shell portion 31b, the interior extraneous air of the T2 of cylinder chamber that constitutes between 35 pairs of air slides itself and the heavy caliber shell portion 31b is exerted pressure, when the pressure in the T2 of cylinder chamber is above above setting, air slide 35 leads on the arm 34 at piston and slide, leave this piston leads arm, with the extraneous air force feed to exit passageway P4.As Fig. 1, shown in the 2 arrow D2.Like this, converge the supply that space R obtains extraneous air, the content that has mixed extraneous air enters from the side opening H that goes into of sparge ring 51, and by the grid 52a foaming of grid ring 52, foamed content is from giving as security ejection end 41 ejections of pressing cover 40.
When finger leaves signature pressure cover, among the small-bore shell portion 31a, the power of spring S produces homing action, piston 32 rises, top, the top 33b of poppet valve 33 is embedded in the passage P1 of piston 32, poppet valve 33 rises jointly with piston 32, leaves introducing port 31h, and content is drawn in the T1 of cylinder chamber by pipeline 31p.Meanwhile, heavy caliber shell portion 31b, the homing action that spring S produces makes air slide 35 lead arm 34 risings with piston, stop up exit passageway P4 in the slip that piston is led on the arm 34, cylinder chamber T2 inside produces negative pressure thus, air slide valve 36 is opened, by extraneous air entrance hole h1 inspiration extraneous air.
By to the carrying out repeatedly of the extruding of give as security pressing cover 40 and homing action, the content that foamer dispenser will mix extraneous air ejects from spraying disconnected 41 with the form of foam.
As shown in Figure 3, the foamer dispenser of this example is gone into the bore ψ 1 of side opening H and is gone into the mutual ratio that side opening H entered, mixed the grid 52a bore ψ 2 that the content of extraneous air is in contact with it from this and be set at satisfied:
φ1：φ2＝1：2.0～3.5
That is to say: the grid 52a of this example has for going into the contact area S2 of side opening H bore area S14.0～12.3 times.Specifically, if go into the bore φ 1 of side opening H be: φ 1=2mm, bore area S1 is S1=3.14mm
2So, be from this bore φ 2 that goes into the grid 52a that side opening H enters, as to have mixed extraneous air content will contact: φ 2=5.6mm, contact area S2 is: S2=24.6mm
2
Shown in Figure 10 (a), regardless of the content shape, the foam F that is ejected in said structure all is minute bubbles B1, quality exquisiteness, expansion, outward appearance elegance, comfortable feel for the user.In contrast, when the mutual ratio of the bore φ 1 that goes into side opening H and the bore φ 2 of grid 52a does not satisfy above-mentioned condition, the foam that foamer dispenser sprayed can produce minute bubbles B1 because of the shape difference of content and air pocket B2 coexists, and is difficult to form the effect of foam outward appearance elegance, comfortable feel.Shown in Figure 10 (b).
As shown in Figure 3, in the sparge ring 51 in this example, go into side opening H and be connected each other by the taper seat 51c that certain slope is arranged with grid 52a.This structure can help the generation of the foam of quality exquisiteness, expansion.In addition, the taper seat 51c that goes between side opening H and the grid 52a at sparge ring 51 can substitute with gradient continually varying flexure plane.
Have, as shown in Figure 2, air slide 35 is divided into two strands up and down with the slipper of heavy caliber shell portion 31b in this form again.And the inwall of heavy caliber cylindrical shell 31b between with sealing gasket 35b and the 35c of the tangible R of confined space circlewise around the piston arm 34.And heavy caliber cylindrical shell 31b is mutual by oral area 11 inwalls of container 10, enters this oral area 11 inside, with containment member (for example liner) the 0 common annular gap C that forms by support cap 20 sealings.This heavy caliber cylindrical shell (cylinder portion) 31b also is equipped with the extraneous air entrance hole h2 that imports extraneous air in container 10.Air slide 35 is in not when the constant state of heavy caliber cylindrical shell 31b slides within, is sealed space r and seals, and air slide 35 is given as security fashionable opening, and extraneous air enters by the extraneous air entrance hole.In this case, because the effect of compression pump, the extraneous air that no longer needs to be provided with in order to eliminate the container 10 inner negative pressure that take place traditionally receives valve.Can reach the purpose that reduces amount of parts, reduces cost.
In this example, go into the cross sectional shape of side opening H on the sparge ring 51, polygonal or circles such as triangularity, quadrangle can be made in the positions such as cross sectional shape of grid 52.When cross sectional shape when being the non-circular shape of representative with polygonals such as triangle, quadrangles, above-mentioned opening bore ratio is for having the quite circular diameter ratio of same area of section with this noncircular cross section.
Other example that is based on bubble generation member 50 on the foamer dispenser of the present invention of Fig. 4 (a)～4 (c) expression.In addition, in the following description, adopt same reference number to represent with the corresponding composition member of content shown in Fig. 1～3, repeat specification will be omitted.
In the bubble generation member 50 of this example, the cross sectional shape that connects the inner passage of sparge ring 51 is circular.Meanwhile, shown in Fig. 4 (a), the cross sectional shape of going into side opening H of this sparge ring 51 also is the circle of opening bore φ 1.In addition, the cross sectional shape of the cylindrical shell 52b of grid ring 52 is set at ring-type.Meanwhile, shown in Fig. 4 (a), the cross sectional shape of grid 52a also is the circle of opening bore φ 2.
In this formation, the ratio of going into the opening bore φ 2 of the opening bore φ 1 of side opening H and grid 52a is set at and satisfies following relationship:
φ1：φ2＝1：2.0～3.5
Even more ideal preset proportion is to satisfy following relationship:
φ1：φ2＝1：2.2～3.2
Concrete example: the opening bore φ 1 that goes into side opening H of sparge ring 51 is set at ψ 1=1.0mm, and aperture area is set at S1=0.79mm
2, the opening bore φ 2 of grid 52a is set at ψ 2=2.3mm.Aperture area is set at S2=4.15mm
2
Under this formation situation, regardless of the proterties of content, the foam quality exquisiteness, the expansion that eject can improve graceful outward appearance and the excellent handle of user when inserting in the palm.Compare more fine and smooth, the expansion of the foam quality that ejects in this case with the situation that is shaped as dihedral of going into side opening H and grid 52a of sparge ring 51.The generation of this effect can be considered because the cross sectional shape of going into side opening H and grid 52a of sparge ring 51 is circle, thereby has reduced the influence that the sparge ring 51 interior chaotic turbulent flows that produce cause.
But in this example, sparge ring 51 inside are provided with is fixed in 2 flanks 53 giving as security on the pressure cover 40 to grid ring 52, and for grid ring 52 being fixed in 2 flanks 54 on the side opening H.Each grid ring 52 is fixed in the sparge ring 51 to be pressed into chimeric mode respectively.This formation design can make the flank 53,54 on the sparge ring 51 that grid 52 is installed on the optional position of these sparge ring 51 inside.
In addition, what Fig. 5 represented is: on the bubble generation member 50 that Fig. 4 (b) shows, press the grid ring 52 of cover 40 1 sides to separate with giving as security, only grid ring 52 is fixed in the state into side opening H one side.What Fig. 6 represented is: on the bubble generation member 50 that Fig. 4 (b) shows, will go into the grid ring 51 of side opening H one side and separate, and only grid ring 52 will be fixed in the state of pressing cover 40 1 sides of giving as security.What Fig. 7 represented is: on the bubble generation member 50 that Fig. 5 shows, grid 52a is arranged at cover 40 state of position in opposite directions of pressing of giving as security.In addition, Fig. 8,9 expressions is: on the bubble generation member 50 that Fig. 4 (b) shows, grid ring 52 is embedded in the method combination of the flank 53 or the flank 54 of sparge ring 51.
That is to say that according to this example, sparge ring 51 inside are provided with flank 53,54.The position of these flank 53,54 decision grid rings 52.Shown in Fig. 5～9, if this formation, can preestablish the desired value of foam according to situations such as the rerum natura of content and purposes.Change the distance to grid 52a easily according to this desired value into side opening H.In this case, only just can satisfy the needs of the rerum natura and the desirable quality, froth of content with the way of the position of decision grid ring 52 pairs of sparge rings 51.And the change that needn't require because of the rerum natura and the quality, froth of content increases the complexity of amount of parts and assembling procedure.
In addition, in this example, also can install in the side of the cylindrical shell 52b of grid ring 52 can demolition, installation in the bar ditch 52c of flank 53,54 (not having diagram).In addition, flank 53,54 can not be installed in the sparge ring 51, and is installed on the lateral surface of grid ring 52.
The present invention is not only applicable to above-mentioned good example, can also implement by the various deformation state.
Though the present invention discloses as above with preferred embodiment; right its is not in order to limiting the present invention, anyly has the knack of this skill person, without departing from the spirit and scope of the invention; when can doing a little change and retouching, so the present invention's protection domain defines and is as the criterion when looking claim.
