The specific embodiment
Distributing box SP forms a vertical part.It is used to distribute paste and even flowable materials M, and its filling volume is kept by the container 1 of a dimensionally stable.
This container 1 is elongated flat shape, and cross-sectional plane is non-circular, is preferably oval (referring to Fig. 2).
The assembly of this container 1 with respect to the axis x-x of its longitudinal center in two.
It comprises shell halves 2 and lower casing half one 3.Open end respect to one another is close together in the plane E-E vertical with the axis x-x of longitudinal center.The molded structure that will illustrate below other, the cavity of shell halves 2,3 is identical.
An angle is outwards departed from open end respect to one another on periphery.In this case, last shell halves 2 forms flanges 4, and lower casing half one 3 forms flanges 5 (also can referring to Fig. 6).
When vertically the seeing of container 1, the flange 4 of last shell halves 2 is vertical folding on the direction on upright surface 6.Corresponding dihedral leg 7 engages with the outside terminal edge 8 of the flange 5 of lower casing half one 3.
Relevant edge contour forms a groove 9 (referring to Fig. 3), is used for flange 5 snug fit with lower casing half one 3.
The inner member that container 1 is installed that is connected to of this accurate periphery edge forms good basis, makes the shape of bag 10 accurate.Described bag is folding, preferably inside outwards can be routed up, and therefore needs elasticity or flexible.
Lower casing half one 3 that can run into when bag 10 should flatten with it and the interior lining of last shell halves 2 coupling.It should with the respective inner walls closed contact of shell of tank half one 2,3.Above-mentioned pasty masses M is between this inwall.
Bag 10 towards plane E-E is remained on the container side by edge 11.In this case, flange 4 respect to one another plays a part jointing with 5 surface as clamp jaw.The corresponding outwards outstanding edge 11 of bag 10 is arranged in jointing zone, equator.In this case, the elastomeric material of manufacturing bag seals simultaneously.This jointing be labeled as 12.As shown in Figure 6, this jointing can have parallel wall, or thickens continuously towards the outward flange wedge shape, makes to form the zone that the bottom cuts.These zones can also be carried out rigidity (positive) as the anchor fitting of strengthening and engage except just nonrigid (nonpositive) connection is engaged.The inlet of this jointing has horizontal converx rounding.This can be avoided on " flattening loose-leaf " cutting action being arranged.
Behind putting bag 10, further crooked this dihedral leg 7 finally engages it with the flange 5 of lower casing half one 3.
Can utilize heating to come crooked this dihedral leg 7.On the other hand, if at least in this shell halves the 2, the 3rd of joint area, symmetrical pivotally, then also can utilize lining cement to connect, lock connection or or even screw connection.
On the side away from this open end respect to one another, this shell halves 2,3 enters the zone that cross-sectional plane narrows down.In this situation, the end in upper taper district is the passage area 13 of the conveying pasty masses M of container 1.In fact utilized this container 1 whole flat width described passage area for circle and diameter bigger.
End towards upright surperficial 6 lower casing half one 3 also enters the zone that a cross-sectional plane narrows down.This tapered zone has upright edge 14.The vertical dimension of described vertical edge makes it form gaps in the bottom 15 times and described upright surperficial 6 of container 1.At the center of this bottom 15 air balance hole 16 are arranged.When bag 10 upward movements, described balance hole can compensate the volume in this bag 10 following zones.
In this passage area 13, last shell halves 2 extends in the attaching parts 17 upwards.This is an integrally formed part.This attaching parts 17 holds the annular bush 18 that diameter reduces.The two structure all is columniform basically.
The relevant head zone of distributing box SP is held manually operated emptying interface pump P.
This emptying that is positioned at the apex region of shell halves 2 on this can be made the actuation button 19 of perpendicular movement with the topside formation of interface pump P.Except its recessed actuation surfaces, also has the acclivitous interface 20 of a side.Described interface is a tubular shape in its end region at least, therefore is suitable for carrying a certain amount of paste or the flowable mass M of thigh.
Utilize this interface pump P to produce negative pressure, this bag 10 of emptying completely effectively.It is outstanding down that bag 10 begins to be, flattens and increase in the assign direction gap direction of the interface pump P of shell halves 2 of saying so more accurately on corresponding towards size and bag 10 then.Throughput direction is represented with arrow y.This direction is consistent with the axis x-x of longitudinal center, and enters the horizontal direction that raises a little in actuation button 19.This actuation button 19 that interface 20 is housed can rotate around the described axis x-x of longitudinal center.This can allow to carry out separately the distribution of handled easily, and though be the oval outer shape of container 1 than long axis on, its than minor axis on or on stepless bonded assembly zone line, all can carry out this distribution.
As mentioned above, because grid 21 is placed on passage area 13 fronts of container 1, therefore conveying can not stay remnants between the inwall of shell halves on the container 2 and this emptying are with interface pump P.Described grid is full of this passage area 13, and is on the contrary mutually in the zone that the convex slight curvature enters the filling volume with the direction of carrying arrow y.Increase rigidity like this.This grid 21 can be independent parts.But also the structure of this basket shape can be molded on this on shell halves 2.Can find out that also this assembly comprises by radially disc 24 (referring to Fig. 4) bonded assembly outer shroud 22 and interior ring 23.Have six radially disc 24 that accurately separate with equal angles each other.
In fact another residually do not distribute the device of pasty masses M for inside emptying has bag 10 with the last shell halves 2 of interface pump P supporting rib 25 to be housed.Like this, described bag even can partly not fall.In addition, it is empty to utilize the lever system (comparison diagram 7) that exposes of this supporting rib 25 that flow feed path W is remained.Bag 10 or its wall can be in the direction of carrying arrow y in an orderly manner towards these passage area 13 motions.When independent formation grid 21, this outer shroud 22 be placed on the head 25 that stretches into this supporting rib 25 in this passage area 13 ' on.Described outer shroud with clamping mode be installed in this head 25 ' on.
Always have eight supporting ribs 25 that distribute with equal angles.These ribs can be molded.The height of this rib increases continuously in the direction of passage area 13, and in the opposite direction forms taper on the inside face of this case surface 2.
As can be seen from Figure 3, the wall of the bottom section 26 of bag 10 is than the side thickness of the bag 10 that forms a cup.When selecting wall thickness total flattening of this bag is without prejudice, that is to say, keep crushable character.Described increase wall thickness is as the bottom effect that strengthens this bag a little.The wall thickness increase can extend to whole bag bottom section 26, or as shown in the figure, only forms a torus section.
One over cap 27 is arranged on the head of distributing box SP.When also having other vessel etc. in the bag of this container 1, can avoid discharge of content so simultaneously with being supposed to.
Utilize this attaching parts 17 and form step transition between the annular bush 18 of shoulder 28, can determine the relative position of this over cap 27.
The lid body can utilize friction force to install, but preferably utilizes screw to connect (comparison diagram 8).The annular bush 18 that is placed in this attaching parts 17 is a part that is placed on the insert 29 in the distributor header.The end of described annular bush is a pedestal 30, and it is positioned on the pasty masses.
Forming above-mentioned emptying stretches out from this pedestal 30 with the part of the cylinder 31 of interface pump P.
Piston 32 moves in this cylinder 31, and this piston can overcome the spring-load that is produced by actuation button 19 and move.Described piston forms the limes superiors position of pump chamber 33, and the lower terminal end in this chamber is a pedestal 30.
One access valve V is arranged in pedestal 30 1This valve is a check valve, and may command is by being combined in flowing of annular opening 34 in this pedestal 30, and is made by elastomeric material.
One outlet valve V is installed on this piston head 35 2This also is a kind of elastomer element of check valve-type.
This outlet valve V 2Keep access portal 36 to close.
At this outlet valve V 2The back one intermediate cavity 37 is arranged, this intermediate cavity with and central aisle 38 fluids of these piston 32 bonded assembly actuation buttons 19 be communicated with.
This central aisle itself 38 is connected with interface 20 again.
In order to form this intermediate cavity 37 and to hold this central aisle 38, with the axle 39 of the back-connected piston 32 of piston head 35 be hollow.As can be seen from Figure, the function part that is used for work suitably is placed on this hollow shaft.
One cup-shaped attaching parts 40 is arranged on this piston.The opening of this glass is towards the direction of container 1.The top of cup is connected with actuation button 19 securely.
Form the block jut 41 of an annular in the outside of this cup-shaped attaching parts 40.The axial groove 42 of the block that described block jut is opposite with the formation on annular bush 18 inboards interacts.The annular width of this axial groove is determined deviation, and forms the gap with the part of pump chamber 33.
The same spring cavity 43 that forms of annular wall of this cup-shaped attaching parts 40 and in the opposite direction open cylinder 31.Place compression spring 44 in the described spring cavity.As shown in Figure 8, this compression spring loads on the direction of home position this actuation button 19.For this reason, the action of the spring in the upper end is the top that withstands on this cup-shaped attaching parts 40, and is to be pressed on the pedestal 30 in the action of the spring of the end of supplying with towards material, and pedestal fixedly is close to.Utilized specific supporting member, disc for example, bead etc.This compression spring 44 has minor shifts.
Paste and even flowable mass M are sent on the pedestal of broad in the zone of dividing equally of distributing box SP (begin is in the pump chamber 33), rather than transmit by the access passage that is positioned at the center.This point can be realized with the ingate of interface pump P by this emptying; The passage area 13 of this ingate and grid protection is contiguous, forms and the bag 10 concentric also forms of coaxial annular opening 34.Be dispersed between the center of the pedestal that forms by disc 45 and the radially contiguous with one heart base region of this annular opening at the annular opening 34 that forms on this pedestal 30 with exterior domain.This disc 45 that is the form of spokes configuration preferably separates with equal angles each other.Same modification forms this annular opening 34 by the hole in a circle hole.This hole separates equably at circumferencial direction.
A described disc interrupt system and a circle hole system also are used in outlet valve V 2The zone in access opening 36 in.
Immerse oneself in the infundibulate widened section of cellular type according to the annular opening 34 of described basic structure and access opening 36 carrying arrow y direction to continue into screw.This can help in discharging and pumping process, rising valve V 1, V 2To open valve.
The general effect that reaches like this is, will by the negative pressure of pump P at the area limiting of the material M that carries arrow y direction " suctions " on zone from broad front portion to transit area, available so simple method is eliminated bags 10 inclination.The inclination of bag 10 can form tiny pocket, results in blockage, and is particularly all the more so in the ending phase of distributing.
This effect is further strengthened at the annular opening that has seizure funnel 46 on the side of material M.Described seizure funnel has been molded in this pedestal 30, and have opposite with assign direction arrow y, be the wall that the revolution symmetric mode is dispersed.The diameter of this annular opening 34 adapts with the diameter of passage area 13 or grid 21 basically.
Be also pointed out that this emptying that is pre-assembled fully can utilize screw to connect with interface pump P and be placed on the neck (i.e. this attaching parts 17) of container 1.Screw thread is represented with 47.At access valve V 1Height on a stop screw 48 is arranged.Described stop screw extends in the shoulder wall towards enclosure.As mentioned above, on this shoulder arm grid 21 is housed.Keep one and distribute cup between this grid 21 and pedestal 30, the wall that it can bedding bag stops up.
Conveying is carried out as follows: moving downward of actuation button 19 reduces the volume of pump chamber 33.Consider access valve V 1Closing function, the material M that is arranged in pump chamber can not discharge in the direction of the supply.In addition, the sealed-in material by this access opening 36 is delivered to central aisle 38 by intermediate cavity 37, discharges by interface 20 from this again.Utilize outlet valve V 2Opening action can open this passage.If press actuation button 19 again after conveying, then piston 32 returns mobile on the home position direction.Like this, in pump chamber 33, produce negative pressure.As a result, material M refills from supply source, access valve V 1Open.Because outlet valve V 2Closing movement, external air can not enter.The returning of piston move to be because the power of compression spring 44 realizes.
