Here, the plastics that vessel 1, end cover body 3, lining 4, cover cap 6, housing 7, operating knob 9, piston 10 and annular movement valve 11 are made up of polypropylene, polyethylene, polyacetal, nylon, polybutylene terephthalate etc. are respectively made.
End component 2 is made of plastics (various thermoplastic elastomer, such as, olefin hydrocarbons thermoplasticity elastic body or styrene analog thermoplastic elastomer) or the rubber that is made up of government rubber (NBR), silaatic, butyl rubber, fluorine system rubber etc. make.
Coil spring 5,12 is made of metal or plastics are made.Ring liner 8 is made up of rubber or plastics are made.
The essential characteristic without gas blowout mist pump machanism shown in figure is,
(11) by the elastic reaction of coil spring 5, via can the lining 4 of up-and-down movement, end component 2 upward direction in the spatial accommodation region of the liquid internal contents limited in vessel 1 is loaded, namely, the direction that discharging operation to this end component and liquid internal contents correspondingly carries out movement loads
(12) lining 4 in order to will be loaded upward by the elastic force of coil spring 5, to revolt the form of this elastic force near its bottom position, coordinate and remain on the end cover body 3 of the lower end side being installed to vessel 1, end cover body 3 is formed end difference 3b down, and the end difference 4c formed on lining 4 upward
(13) by the relative rotating operation of vessel 1 with end cover body 3, this end difference 3b down and the mated condition of end difference 4c is upward removed.
The mated condition of above-mentioned (12), because end component 2 is set at its position roughly most on the lower, so, under state before the fore side pump cellular installation shown in Fig. 5, the Fig. 6 that will be made up of " cover cap 6 ~ coil spring 12 " is to vessel 1, namely, under the state of the upper end side opening of vessel 1, easily and reliably can carry out the operation (with reference to Fig. 1) from this peristome, liquid internal contents being filled into vessel inside.
In addition, under this mated condition, lining 4 amount to that four outside protrusion 4g enter vessel 1 respectively amount to four concavity portion 1d, this lining and this vessel become form locked in rotation direction.
And, after the end-of-fill of liquid internal contents, by carrying out the relative rotating operation of vessel 1 and end cover body 3, the lining 4 that rotation direction is in the lock state with this vessel 1, offsets to circumferential direction relative to this end cover body 3 mated condition before this.
By the skew to circumferential direction of this lining 4 and end cover body 3, the mated condition of the end difference 3b down of this end cover body and the end difference 4c upward of this lining is removed.
Along with the releasing of this cooperation, lining 4 and be equipped with the end component 2 of the face portion (upper surface portion of leg 4f) contacted with its flange portion 4e, can interlock (with reference to Fig. 2) in an upward direction.
Here, why can in an upward direction interlock be because, by the leg 4f of the lining 4 that the elastic force of coil spring 5 loads upward, by the directional tagging of the conical surface 1e inwardly of the concavity portion 1d of its conical surface 4h outwardly and vessel 1, displacement is to the inside while be moved upward from this concavity portion.
When this cooperation by under the state removed downwards bulldozing operation button time, as hereinafter described, piston 10 moves down, and the pressure of the liquid internal contents of housing 7 increases, and whereby, annular movement valve 11 is moved upward relative to this piston.
Therefore, the outflow valve be made up of the circular cone 10k of lower piston component 10j and the valve action portion 11b of annular movement valve 11, shifts from contact condition before this to released state (with reference to Fig. 5, Fig. 6).
Opened by this outflow valve, the liquid internal contents of housing 7 etc. push by piston 10 or by the base plate 2 loaded upward, this liquid internal contents by the hole portion 9b from operating knob 9 externally area of space discharge.Along with the discharge of this liquid internal contents, the pressure of the liquid internal contents of vessel, enclosure interior reduces.
In the mode that the Pressure Drop low degree to this liquid internal contents is corresponding, by the barometric pressure of outside and the elastic force of coil spring 5, drive end component 2 upward.
Shown in figure without gas blowout mist pump machanism, because the coil spring 5 loaded upward by end component 2 using use is as prerequisite, so, this end component 2 finally moves to its uppermost position, reliably can carry out substantially whole discharging operation (with reference to Fig. 3) of liquid internal contents.
In addition, the number of assembling steps of said vesse base side unit, such as, be:
(21) end component 2 is loaded vessel 1, makes it and its inside face frictional fit,
(22) after coil spring 5 is clipped on end cover body 3, the end difference 3b down of this end cover body is installed on lining 4 in the mode that the end difference 4c upward with described lining 4 is chimeric,
(23) with the upper longitudinal of described vessel to the consistent mode of the longitudinal concavity portion 3f in bottom of concavity portion 1b and cover body of the described end, the end cover body 3 that will carry out after above-mentioned (22) operation is installed on the vessel 1 that carried out after above-mentioned (21) operate.
When the installation of above-mentioned (22), such as, when the lower lappet portion 4b of lining 4 is loaded from the top of the erected piece portion 3a of end cover body 3, first, the conical surface 4d outwardly in this lower lappet portion contacts with the conical surface 3c inwardly in this erected piece portion, and the plastic portion of both sides is to revolt respective elastomeric mode displacement in the direction away from each other respectively.
And, when the lining 4 end difference 4c be moved down into upward becomes the position of end difference 3b down, lower lappet portion 4b and erected piece portion 3a returns to initial condition by respective elastic force, transfers to the mated condition of end difference 4c upward and end difference 3b down.
After the installation carrying out above-mentioned (23), four the protrusion 4g outwardly that amount to of lining 4 are coupled on the concavity portion 1d of vessel 1 respectively.By this cooperation, vessel 1 and lining 4 are configured to lock-out state relative to rotation direction.That is, when making vessel 1 rotate, lining 4 also integrally rotates with it.
The fore side pump unit of Fig. 5 and Fig. 6 itself is known, under the still-mode of Fig. 5, become following state,
(31) housing 7 is fitted on the annular concavity portion 6b of cover cap 6,
(32) piston 10 of enclosure interior and annular movement valve 11 are loaded upward by the elastic force of coil spring 12, the 11e of falling skirt section of this annular movement valve contacts with the annular step portions 6c of cover cap 6, further, the circular cone 10k of this piston and the valve action portion 11b close contact of this annular movement valve.
That is, because the outflow valve of circular cone 10k and valve action portion 11b cuts out, so the liquid internal contents be contained in housing 7 grade is not discharged from hole portion 9b.
Then, when push-down operation button 9,
(41) with operating knob 9 all-in-one-piece piston 10, the elastic force of revolting coil spring 12 moves down,
(42) along with the pressure moving down the liquid contents of the enclosure interior caused along with this increases, annular movement valve 11 moves up relative to piston 10, and its 11a of falling skirt section is engaged on the annular top surface 10h of upper piston component 10a.
That is, annular movement valve 11 moves up relative to piston 10, and the outflow valve of circular cone 10k and valve action portion 11b is opened, and the liquid internal contents of housing 7 is discharged by from hole portion 9b.
The discharge path of liquid internal contents at this moment, as shown by arrow A, roughly become " the longitudinal channel-shaped portion-breakthrough part 10g-upper shed spatial portion 10b-passage portion 9a-hole portion 9b between the longitudinal rib 10f of the longitudinal channel-shaped portion between the inner space area-hole portion 10m-circular cone 10k of housing 7 and outflow valve-longitudinal rib 11c of valve action portion 11b-minor diameter constitute sheath-like portion 10e-".
Then, when the push-down operation of operating knob 9 is removed,
(51) operating knob 9 and piston 10 move up by the elastic force of coil spring 7,
(52) along with this movement upwards, the volume of the liquid internal contents housing region of enclosure interior increases, and reduces with the internal pressure at this place and combine, and the outflow valve of circular cone 10k and valve action portion 11b also transfers to closed condition,
(53) fore side pump whole unit returns to the state of the still-mode of Fig. 5.
Along with the pressure of above-mentioned (52) reduces, liquid internal contents flows into from vessel 1 to housing 7, with the amount of this inflow accordingly, end component 2 moves up.Discharge object when the liquid internal contents operating knob become next time of inflow enclosure interior pushes.
In addition, due to the packing interaction by the annular convex shaped part 6a of this cover cap and the annular concavity portion 1g of this vessel, cover cap 6 is installed on vessel 1, so, can say that cover cap 6 can not be unloaded from vessel 1 unintentionally simply.
That is, can not occur in cover cap 6 unintentionally by under the state that unloads from vessel 1, end component 2 is due to the elastic reaction of coil spring 5 is moved upward, the liquid internal contents of internal tank flows out from container body openings portion situation.
