Description

The dosimeter that is used for container, conduit or the analogue of one or more liquid

Technical field

The present invention relates to a kind of dosimeter of type described in claim 1 preamble.

Background technology

This class dosimeter is installed in an end of tube container or analogue usually, takes up certain liquid of preparing sale in the container.That these containers can be made firmly by certain or deformable plastic material, metal sheet, aluminium matter sheet plate or analogue are made.These containers can be furnished with possess certain or multiple different may shapes piston and be used for the actuator of piston; And/or this piston can be designed to be extruded so that throw in inclusion in the container.Liquid can be glue, aquaseal, medicament, medical product, food etc., and can have denseness arbitrarily, such as being easy to flow or viscosity.

People make every effort to accomplish, this class dosimeter finish can realize after once throwing in satisfied and particularly air-tightness seal; And obtain to throw in uniformly; And be with termination lavishly to throw in suddenly and not; And as far as possible fully empty utensil.Sometimes people made every effort to obtain a kind of in these characteristics just is several sometimes and be that all this decides according to concrete application sometimes.Be contained in dosimeter in a certain conduit or the analogue by use, liquid is thrown in and will only be achieved more than a certain stress level automatically, and can realize rapidly below the described stress level and do not throw in the interruption of waste by reaching.

Summary of the invention

But, often can not reach fully or can not reach the target of being pursued with satisfied or failure-free mode.Main purpose of the present invention is, finish always can obtain to be satisfied with fully after once throwing in, failure-free and bubble-tight sealing, regardless of the viscosity of used liquid.Preferably can take extra safety measure, detent position can be guaranteed and improve to these measures.

In addition, according to the present invention, if desired, certainly might be suddenly and be not with lavishly and as far as possible fully stop respectively throwing in and empty container.Under the situation of known various dosimeters, throw in almost normally in uncontrollable mode and finish, promptly may take place to drip and drop down or backflow.Adopt the present invention to stop this phenomenon with effective and efficient manner.

Another shortcoming of known various technology is that required strength is improper when delivering, and uses relatively large strength but still to obtain limited input such as needs, perhaps uses less relatively strength can cause too much input.Thereby the objective of the invention is in this respect to make that a kind of control setup that can carefully regulate becomes the even input that may obtain requirement with the speed of suitable strength and hope.This means, might control agent use a certain required volume, that is to say, thereby will begin to obtain required volume eventually and will can not consume any unnecessary energy.This is a key factor in the tenure of use of product.

The structure of known various dosimeters installs often more complicated, costliness and consuming time.For disturbing very sensitive and often not forming one or do not adapt to container with container.The functional of them may be adversely affected under long term storage time or changeable condition of storage.At last, the design of these dosimeters and laying often causes utensil to be easy to impaired and its function is endangered.

Described structure can cause multiple environmental consequence, and this is to pay attention to and is crucial factor in modern product.

Because described design, caused various chances and allow whole dosimeter only with a kind of manufacture of materials and can regulate with the material coordination of container.Thereby whole device can reuse, and feasible harm to environment reaches minimum.In some known structures, often use different materials, this means that these utensils can not utilize again in certain suitable mode.Thereby, from the viewpoint of measures of society, importantly, adopt the structure that does not need primary resource.According to a kind of so just structure of dosimeter of the present invention.

Another important function of new structure is, compares with known various solutions, can not leak in uncontrollable mode after it uses with the container/bottle device of crossing, almost empty.

Aspect all, the present invention will provide important improvement or eliminate exist not enough and dangerous.In addition, the present invention will multiple other aspect develop recent development in this area.Some of them be respectively utilize again with integration may, that is provide and have fully or to the container of small part integration dosimeter, up to the present, they often by other manufacturers and/or with other such as the metallo-material manufacture, and metal is easy to encourage the risk that functional issues etc. occurs.

These purposes are that the dosimeter by the sort of type that relates in a kind of described method of describing with claim 1 characteristic of main design is achieved according to the present invention.

The specific embodiment

In the accompanying drawings, a kind of rotational symmetric container 1 is shown, has the anterior supporting plate 2 that suitably a little outwards protrudes, it mainly is columnar delivery device or socket 3 with external screw-thread 4 that this front portion supporting plate is furnished with preferably on extrusion position at center shaft, the device lid 5 that is designed for screwing on and has respective inner screw thread 34.This device, and may be the part of wallboard 2 can be an independent parts (not shown) in addition, can be inserted in the aperture on the designed described wallboard of purpose for this reason.The design of this pattern may be preferred, because it is suitable for charging from the place ahead the then adaptive delivery device of container.Under situation about at first mentioning, backward or the container that opens wide downwards charged from this back one direction, and primary piston 6 fits on the same direction, perhaps the rear end of container or lower end 7 are sealed by welding.At last, container, input socket and remaining input device can give integrated according to Fig. 5 and 6.

Container is suitable for by plastics, is particularly made by polyethylene or polypropylene.But, certain metal, particularly aluminium can be used as equivalent material.

In the aperture 8 of throwing in socket, the antelabium 10 along inwardly outstanding all around comprises that one holds a device and a valve seat, and antelabium suitably leaves 9 one very little distances of spot face in a practical embodiments, is provided with such as 3-20mm.Antelabium 10 can be thought a cone, and it cooperates the main body 21 of valve member 20 also therefore to manifest and extrudes a kind of interruption of encapsulation medium, the function of restriction from container.Antelabium is preferably suitably made respectively via jet molding and is bonded together with socket and entire container, and general or average angle 30-60 °, gradually narrow mode turns forward tiltedly outstanding towards the center of spot face with the band tapering under preferably about 45 ° situation.Being formed among Fig. 7 of tapering illustrates and illustrates out with details, its be by towards the rear end 7 of container slightly more longways at the shoulder 11 that extends axially antelabium so that strengthen supporting for antelabium free end zone 12 towards described container end portion.The downside 13 of antelabium shoulder preferably mainly is straight, comprise the only about half of of this side of antelabium and form about 20 ° angle with socket cylinder shape inner wall 14, the remainder of downside is preferably straight, and antelabium is thereon on the side 15, except the faint recessed arching in shoulder place, mainly be that socket wall portion straight and on himself and opposite forms average 40-80 °, preferably about 60 ° angle.Be connected with side 13, antelabium forms the suitably recessed slightly side 16 of a weak point on its downside, thereby be easy to from upside 15 diverge to and via one comparatively significantly inflexion point 17 to change into mainly be straight release side 18, engage at the distal-most end place of upside and to form a sharp-pointed lip point sword 19 together, angle is 10-40 °, preferably 25 °.5-45 ° in socket axis on release side 18 is extended around the socket imagination, preferably about 25 °.Antelabium occupies about 30-70% of aperture 8 cross-sectional planes, that is extends through about 10-50% of aperture 8 diameters.

The lower end of container or rear end 7 can be sealed on after charging in charging the station at container in some cases.Under some other situation, this end can be let alone to open wide and can put into piston 6 at this end after charging.In both cases, suitable is to be achieved by vessel head is overturn down, but socket or analogue 3 must at first be sealed, and is used for automatic sealing in particular for its configuration valve body 20.

Valve body 20 has bar-shaped or mainly is columniform main body 21, its front end or outer end 22 comprise one forward or outside, preferably have a mild button-head 23 that circle tightens up edge 24, this edge is given prominence to above described main body and is positioned at respect to described main body one at least mainly is radially plane.Be connected with the described edge that tightens up, described termination form one suitably for axially or with faint tapering, short cylindrical shape surface 25, be transformed into a mild circular major surface via a little bending spring.As another program, the termination can be designed to a cone.

The rear end of main body 21 or lower end 26 suitably end-stop are transformed into cup-shaped spring 28 at 27 places and at this, are bonded together with body rear, suitably are designed to one haply and have 30-60 °, the truncated cone body of preferably about 45 ° cone angle; Open forward, that is surround body rear in a certain distance that increases gradually from end surface 27.In this connection, a cup-shaped spring is defined as around the elasticity or the elastic force apparatus of arbitrary type of administered.Thereby it can be such as the many plates that separated each other by some gaps, pole and even rope yarn.But, cup-shaped spring 28 preferably mainly is the source for the basic configuration of a certain cup or plate and has homogeneous thickness, but it finishes with radial front end surface 29 haply, and a tip outward-dipping a little and that stretch out forward forms about 30 a ° angle.This tip sphering slightly a bit that is has the bending spring of 0.2-1mm.From end surface 29 in the cup-shaped spring or the transition of front surface 30 comprise that one has the very rounded edges of small-bend radius form one 130-170 °, preferably about 150 ° angle because described each surface is common.In addition, the cup-shaped spring is furnished with many eyelets 31, along its peripheral rectangular distribution, has than major diameter, such as from the 15-40% of described main body spring development length and be through hole, runs through as the crow flies, passes main body possible coaxial line.Replacing each eyelet of any design-calculated, can adopt such as aperture some slotted eye shapes, that radially stretch, may be that some are free-ended aperture at cup or plate periphery place.

The diameter of described main body is than the little 10-50% of width in socket aperture 8.Like this, can obtain to have the input duct of enough big cross-sectional area.The front end 22 of main body preferably has identical diameter with rear end 26, but can stretch a less or bigger concentric diameter reduction section 32 between the at both ends.To be convenient to production like this and cause material to be saved.(as Fig. 5 and 6) in some cases tightens up edge 24 and can extend inside diameter reduction section 32 also form V groove 33 with it jointly, and wherein cylindrical-conical haply lip point sword 19 can be introduced and guarantee that so respectively special actv. supports action and sealing.As another program, diameter reduction section 32 can penetrate and tighten up edge 24 and penetrate end 22 to a certain extent, perhaps can adopt some terms of settlement that are similar to above mentioned various terms of settlement, that is part 24 and part 32 can have an inside minute angle.

The design that is shown in Fig. 1 and 2 plays a role with the following methods: in Fig. 1, container 1 fills with liquid device lid 5 and is screwed in fully on the socket 3 downwards.The device lid, may have internal boss 36, abuts head 23 also may compress some downwards with it a little respectively and withstands and tighten up edge 24 and may be V groove (see figure 7) on the lip point sword 19, particularly under one situation of back, except its integral body of antelabium, also all expanded and/or be allowed to penetrate the material of rod-shaped body 21 a little, so that increase sealing load and make joint more effective with a certain distance.But, have its device lid or not with the valve member 20 of device lid all between antelabium 10 and free wall portion 2 a little by prestress, that is antelabium is tending towards inwardly pushing valve member, and cup-shaped spring 28 trends towards valve member and then draws in container.In a practical embodiments, whole prestress distance can be 1-10mm, preferably about 2mm, and the described collaborative work between device lid and the valve member, when the latter is subjected to certain pressing down, have benefited from the antelabium peripheral region and the prestress that prestored slightly, but preferably the cup-shaped spring is not wanted complete obiteration against the elastic force of antetheca.But, the cup-shaped spring is disengaged somewhat the antetheca and its front end, exterior tip recline slightly.

One when removing the device lid or replacing nozzle 35 according to Fig. 4, then at first prestress is regulated, in case the pressure effect has been applied on the valve member, then holding with sealing function of antelabium just reduced a little.In case wish to throw in the part of inclusion in the container, the elastomeric wall so that increase of extruding respectively acted in the container pressure on the inclusion and such as power piston 6, increased the pressure that acts on the cup-shaped spring and with trend extrusion spring from internal tank in addition towards antetheca recovery level slightly, until the valve body front end lifts and makes antelabium mainly radially outwards to be subjected to elastic restraint from antelabium 10 till, this moment, annular groove 37 was formed between antelabium and the rod-shaped body 21, and liquid is propagated and seen through each aperture 31 and enters and throw in device eyelet and described circular clearance and outflow input device or analogue and the flow direction and use zone (Fig. 2).During throwing in, cup-shaped spring, each aperture on it and will combine with the device lid that elastic type is contained in outside, described circular clearance and form a certain unmodified basically and throw in pressure, it can be very uniform causing input.Antelabium plays an important role with the form of valve cone at this moment, and it centers on rod-shaped body 21, thereby designs to such an extent that can control the liquid stream of being thrown in.Gap between antelabium 10 and the main body 20 can be according to there being media type to be controlled to be selected.In case it is too low to throw in pressure, valve member 20 and antelabium 10 will be closed respectively.In case it is too high to throw in pressure, the cup-shaped spring, each aperture and antelabium all have shock damping action it on, are that injected volume is increased and input speed is able to slight increasing slightly.By size being determined to corresponding degree and, might controlling input on a large scale for these parts perform mutual big minor adjustment.In case wish to stop throwing in, the operator just removes and acts on the pressure on the inclusion in the container, and the cup-shaped spring is owing to its intrinsic elasticity bounces back into the off position that it is shown in Fig. 1.When spring rebounds, whole volume between spring cup spare, antetheca and the valve member increases and causes faint vacuum, this phenomenon can be eliminated, part is because liquid is sucked into described volume and part from internal tank via each aperture on the cup-shaped spring is because the external freedom end of the input device of liquid beyond valve body termination 23 and the antelabium 10 and be sucked out via circular clearance 37, quickened valve closing like this, particularly owing to also on whole downside of antelabium and release side, obtained described vacuum.The size of this level of vacuum can be by changing spring force size and be adjusted to the situation that is suitable for various application occasions thereupon and changed.But, vacuum is so faint, so that do not have air to be sucked into container from the outside, because just very little a part of space is filled with liquid or by liquid film and covered, is enclosed in beyond the antelabium.When valve closing, pressure control and the latter's residual elasticity have just taken place via each aperture on the cup-shaped spring, that is the elasticity of withstanding the antetheca inboard pressure that reclines, it keeps valve closing.

Getting loose between moving period of described cup-shaped spring, Free Surface 29 is along the antetheca inner slide, at first forms moving contact (Fig. 2) from inboard 30 paths to surface 29, be then whole surperficial 29 and final (Fig. 1) be positioned at radially and outside band nose part.When closing change for input, process is opposite.This means that cup-shaped spring tip and antetheca inboard are protected, and these parts can there be fatigue or do not have interference on the function and the very long life-span of acquisition.

After throwing in, device lid 5 suitably is screwed to once more to be thrown in above the device and obtains above-mentioned effect.In case the inclusion in the container is a glue, suitably wait for a moment, till the glue residue in input device outermost part has been solidified and can have been taken away.In case the use nozzle just may be thrown away it together with the glue residue of solidifying in it and the dosimeter aperture, will adopt a new nozzle to be engaged in once new input this moment after a while once more.

In the embodiment that is shown in Fig. 3 and 4, there is not aperture 31 on the cup-shaped spring and rod-shaped body 21 is hollow.The cavity 38 of Chang Kaiing extends front rod end 22 always backward, vast sky chamber 38 end-stop there, but throw in eyelet 39 via each and be communicated in this zone in addition, rod zone, these eyelets pass Subject Extension and along the periphery setting, and they suitably have the rectangular profile of level and are covered by device lid 10 on its off position.Because from the release side 18 of sharp sword 19 antelabium can if be arranged on the below of respectively throwing in eyelet 39 around the cusped edge 40 of main body lateral expansion, then may be favourable downwards with more outward-dipping.Show among Fig. 3, cusped edge 40 a bit stops liquid to penetrate hollow space 41 between main body 21, cup-shaped spring, antetheca, input device and the antelabium penetrating antelabium on the off position, this may be very important in some cases, under the situation of filling at hollow space 41 with air or another liquid.Cusped edge is all right, on the open position in Fig. 4, keep the lip point sword to leave very little distance of main body so that guiding lip point sword, move towards in the way of its off position at it, cross and respectively throw in eyelet and just after crossing these eyelets, just allow the lip point sword close cusped edge of each eyelet and its wall portion that reclines, if not, will damage the lip point sword.

This embodiment plays the same effect with described first embodiment in another way, but the inclusion of container is not through the cup-shaped spring and via the rod-shaped body feed, and when a certain stress level has reached, throw in the eyelet feed, valve member was moved away and was respectively thrown in eyelet and expose from antelabium slightly this moment via each.When pressure has dropped to described stress level when following, the cup-shaped spring will be pulled to valve body the off position according to Fig. 3 once more.

In Fig. 5 and 6, show an embodiment of container, be substantially similar to the embodiment that meets Fig. 1 and 2.Replace first embodiment, among this second embodiment, a shoulder is configured in to be thrown among the device 3, preferably makes one with an elongated shape and container.Rear container end 7 is open to till charging, and then will be closed, preferably with the welding (see figure 6).

Being shown in embodiment among Fig. 8 is particularly suitable for being installed within the conduit 44 or within the container tube.This kind device comprises the plunger 45 that has columnar outside face, before it/and outer end is a spot face 9 and thereafter/inner as described abutment wall portion 2.Portion within it, embolism is designed to meet the design of Fig. 1 and 2, may be the design that meets Fig. 3 and 4.Valve is also according to these graphic designs or according to remaining some graphic designs.This design-calculated advantage is that it can be used on the common container tube or catheter design, there, tightens up in a known way and finishes.Thereby, when this design and installation is within a certain conduit, power and prestress at the cup-shaped spring at this place are preferably very large many than power that is used for Vessel Design and prestress respectively, this just can be by selected described power/prestress the acquisition way, this method allows to realize throwing in automatically when being higher than a certain corresponding stress level and realizes not having automatically to waste closing equally when stress level is lower than described level.Also have, it is uniform that liquid fails to be convened for lack of a quorum.

11. as any one described dosimeter among the claim 1-10, it is characterized in that, the cup-shaped spring is a complete closed, and rod-shaped body (21) is made hollow and is had hole (38), the front end (22) of rod is opened wide and preferably stretches to always in the hole backward, preferably end-stop but of described there hole (38) via tiltedly wearing main body, the eyelet (39) of respectively throwing in along circumferential distribution is communicated in zone in addition, this bar-shaped zone, these eyelets suitably have the rectangular section of level and are covered by antelabium (10) on detent position, and be around each throws in eyelet (39) lower body outside, preferably to be provided with the lug, nib (40) of a band point, this lug, nib is designed to be able to such as a bit stoping liquid to penetrate main body (21) by penetrate antelabium on detent position, the cup-shaped spring, antetheca, described hollow space (41) between socket and the antelabium, and/or be that this lug, nib is designed to be able on the open position lip point sword remained on the slight distance place of leaving main body, during near detent position, guiding lip point sword is thrown in eyelet and is only just being allowed the lip point sword to cover each eyelet through after these eyelets through each with box lunch.

12. as any one described dosimeter among the claim 1-13, it is characterized in that, particularly for unidirectional purposes, the function of antetheca (2) is transferred to an inboard shoulder of socket (3), the shape that socket preferably elongates and make with container and be bonded into one, rear container end (7) is preferably opened wide, till charging, this rear end is designed to such an extent that can be closed after charging, and preferably uses welded closure.

13. as any one described dosimeter among the claim 1-14, it is characterized in that, this utensil comprises outside, be circular plunger (45), before it has/and the outer end is as eyelet plane (9) and have back/the inner, and the latter will play the effect of abutment wall portion (2), and have the central through hole (8) between these two ends, together with the antelabium that is used for valve body (20) (10), this plunger design gets and can be fixed tightly in container tube (3), conduit (44) or above the analogue.
