This insertion portion 9 is included in two lateral plane 19a and 19b(Fig. 2 and 3 of the longitudinal axis I-I both sides of this main body 8).Described two lateral plane 19a and 19b(Fig. 2 and 3 that are parallel to longitudinal axis I-I) be designed for and allow the insertion portion 9 of this main body 8 to be inserted in the neck 5 of this container 2.

Therefore, the width 190 of this insertion portion 9 at described two lateral plane 19a and 19b place is designed for the diameter D of the neck 5 that is less than this container 2.

Alternatively, the insertion portion 9 of this main body 8 can comprise some non-parallel, non-symmetrical lateral surface or unique side surfaces.Main points are the enough distances that allow this insertion portion 9 to be inserted in this neck 5 and allow to insert the seal 15.

This exposed portions serve 11 comprises the fluid axial passage 12 running through, fluid flow pass 13 and threaded portion 11a at it on the outside face near sealing shoulder 14.Once described fluid flow pass 13 and fluid axial passage 12 communicate with each other, allow this dosage lid 1 to be assembled on this container 2, the product being contained in this container 2 flows out.

Shoulder 30 in the middle of this fluid axial passage 12 comprises, this centre shoulder is arranged on the pars intermedia office between described fluid flow pass 13 and the upstream orifice 12a of fluid axial passage 12, has the surface towards upstream orientation.

The seal 15 be annular and be configured as be supported on sealing shoulder 14 and neck front surface 6 on.

This installation ring 16 comprises the part 25 of substantial cylindrical, and this substantial cylindrical part 25 has the screw thread openings of running through 24, and peripheral skirt 20.The Design of Screw Thread that runs through screw thread openings of described installation ring 16 is used for corresponding with the screw thread of the threaded portion 11a of this exposed portions serve 11.

This obturating element 17 can stop up and selectively opened this fluid flow pass 13.This obturating element is controlled by operating element 18, and this operating element can touch in the exposed portions serve 11 of this main body 8.

This obturating element 17 is the bars that comprise two annular groove 22a and 22b, described annular groove there is the profile of circular cone and each other according to being greater than this fluid flow pass 13 and middle shoulder 30(Fig. 4) between the spacing of axially spaced-apart longitudinally diverge to.

Each annular groove 22a and 22b are equipped with plug for seal part, are respectively 23a and 23b.Each plug for seal part 23a and 23b can be preferably elastomeric and have cylindrical tubular, and it has the round section of constant thickness.Upstream annular groove 22a has the degree of depth reducing to this upstream orifice 12a direction.

This obturating element 17 comprises the centre portion 170 between described two annular groove 22a and 22b, and this centre portion 170 is columniform in the embodiment of Fig. 1-Fig. 7.Yet this centre portion 170 can be also frustoconical, or any shape of more broadly determining according to the granularity of fluid to be allocated.

Fig. 5-Fig. 7 shows the slip of this obturating element 17 in this fluid axial passage 12.

Fig. 5 shows the dosage lid 1 at blocking position P1, wherein being contained in product in this container 2 cannot be to the outside drain of this container 2: this upstream occlusion sealing member 23a joins in the cylindrical part with minor diameter of this fluid axial passage, between this fluid flow pass 13 and middle shoulder 30, therefore guaranteed this fluid axial passage 12 of sealing obstruction.

Fig. 6 shows the obturating element 17 in this centre portion P with high range.In this midway location P, this upstream occlusion sealing member 23a is perpendicular to this centre shoulder 30, and realizes part and open by allowing pressure fluid move axially according to user traffic flow that this obturating element 17 controls.The truncated cone of this annular groove 22a is oppressed upstream occlusion sealing member 23a gradually, thereby allows to open gradually.

Fig. 7 shows the dosage lid 1 in open position P2, is wherein contained in product in this container 2 by the outside discharged to this container 2.

As shown in Figure 5, when described obturating element 17 is in blocking position P1, fluid cannot be discharged, because blocked element 17 shutoff of fluid axial passage 12.By the internal pressure of this container 2, this obturating element 17 is pressed towards outside, its stroke is arranged on shoulder 26 restrictions on this obturating element 17, the axial middle shoulder 30 against this fluid axial passage 12 of described shoulder 26, thus avoided this obturating element 17 to leak.

By upstream occlusion sealing member, 23a has guaranteed the leak tightness in blocking position P1, and this upstream seal 23a conical pressure is by the wall of this fluid axial passage 12.

Under the overpressure situation that exceeds definite force value of the inside of container 2, by leaking in sealing member 15 and the space E between described peripheral skirt 20 and container 2.

When user applies power F(Fig. 7 on described operating element 18) time, the bar of this obturating element 17 slides in fluid axial passage 12.Described fluid does not leak out because of this upstream occlusion sealing member 23a, and this upstream occlusion sealing member 23a is always pressed against on the wall of this fluid axial passage 12.As what be appreciated that from Fig. 6, this obstruction efficiently and is economically guaranteed by the cylindrical plug for seal part 23a being bonded in truncated cone shape annular groove 22a.

Fig. 7 shows the element in open position P2, and wherein fluid is discharged.This obturating element 17 is fully reduced to destroy leak tightness at this upstream occlusion sealing member 23a place.

Therefore fluid, by controllably discharged to outside, first passes through this fluid axial passage 12, then passes through fluid flow pass 13.This second plug for seal part 23b has guaranteed for avoiding a certain amount of fluid can be by the leak tightness of taking out towards operating element 18.

Described operating element 18 is a kind of covers that are fixed on the tapped bore 18a on the distal threads end of this obturating element 17 for screw thread that are equipped with.Alternatively, this operating element 18 can connect by embedding, inlays connection, and cuff connects or bonding is fixed.

In described embodiment, the springing 17b of coil spring type is bonded between this operating element 18 and main body 8, thus when pressure at container 2 inner too small or when fluid is viscosity auxiliary closing.

Described springing 17b always not independently, can consider that the pressure of these container 2 inside is enough used for allowing this obturating element 17 to slide into described blocking position P1 together with the fluid to be allocated being applicable to.

If needed, the fluid holding in this container must be filtered in advance.

Fig. 2 allows to make an explanation to implementing the element assembling sequence of this dosage lid 1.

In the inside of this installation ring 16, sealing member 15 is set, thereby once complete overall package, the seal 15 just realizes sealing at neck 5 places of this container 2.Be slidably installed removed operating element 18 obturating element 17 in fluid axial passage 12, now this obturating element 17 is bonded in upstream orifice 12a.This plug for seal part 23a and 23b are installed in advance in the annular groove 22a and 22b that are separately positioned in this obturating element 17.The installation ring 16 that is equipped with sealing member 15 is bonded in described main body 8.The distal end 17a that this obturating element 18 is threaded onto to this obturating element 17 is upper, thereby by screwdriver, is bonded on the rotation that gap 17c in the proximal end that is arranged at this obturating element 17 stops this obturating element.Alternatively, described gap 17c, can design any other retaining means, and described gap 17c can have any profile.

Then, can insertion portion 9 be inserted in the neck 5 of this container 2 obliquely.Describedly be inserted through the existence of two lateral plane 19a and 19b and become possibility.Then, this dosage lid 1 is arranged so that this outer radial periphery outshot 10 engages on described neck inward flange 7 against ground.

Then, installation ring 16 is threaded on the threaded portion of exposed portions serve 11 of this main body 8.This installation ring 16 axially clamps described the first sealing member 15 against this neck front surface 6 and sealing shoulder 14 ground.This dosage lid 1 is implemented with the assembling of described container 2.

This peripheral skirt 20, around the neck of this container 2, reserves at the end edge 21 of this container 2 and the leakage space E between periphery wall 4 simultaneously.

The present invention carries out the safety that security leak guarantees user while also reaching in these container 2 inside by the maximum pressure when predetermined.For this reason, described lateral plane 19a and 19b retreat and arrange so that they allow the part of neck to be slightly out of shape, thereby have realized the still less region of resistance.Therefore,, when predetermined maximum pressure is reached, neck 5 is flattened by less to dimensional deformation and sealing member 15, thereby has produced security leak.

Described the first embodiment is more particularly suitable for the fluid that granularity is less than 500 microns.

Fig. 8 and 9 shows the second embodiment of the present invention, wherein this container 2(Fig. 1) by dosage lid 100, closed.As in the first embodiment, this dosage lid 100 is threaded connection and is assembled on this container 2.

Same main device is by designated identical in Fig. 1-Fig. 7.

This dosage lid 100 comprises the main body 80 with longitudinal axis II-II, sealing member 15, installation ring 16, plug members 40.

Main difference between the first and second embodiment is the following fact: this obturating element 41 and operating element 42 are single piece and have realized this plug members 40 in a second embodiment.Alternatively, this operating element 42 can be by bonding, embeds cuff or be threaded and the parts that insert.

Fluid axial passage 12 comprises threaded portion 12b, lower shoulder 43 and middle shoulder 44a.Described lower shoulder 43 is arranged in the midway location between fluid flow pass 13 and the upstream orifice 12a of fluid axial passage 12.

This plug members 40 can stop up and selectively opened this fluid flow pass 13.It is controlled by the effect of user on operating element 42 directly, and described operating element 42 can touch in the exposed portions serve of this main body 80.

This obturating element 41 is the bars that comprised 4 parts.The 41a of top first its near the part of this operating element 42 on part be processed with screw thread.Second portion 41b has the diameter reducing and comprises the annular groove 45 with two truncated cone profiles.

This annular groove 45 always can have any other and realize protruding form, for example spheroid profile.

The described 41a of first is connected by shoulder 44a with second portion 41b.This third part 41c has truncated cone profile and is connected with tip the 4th part 41d of the end of described bar.

This annular groove 45 is equipped with closes sealing member 46.Just as in the foregoing embodiment, this to close sealing member 46 can be preferably elastomeric and for cylindrical tube, this cylindrical tube has the round section of constant thickness.This annular groove 45 has the degree of depth increasing to this upstream orifice 12a.

In this embodiment, this dosage lid 100 also comprises the shut-off block such as pearl 47, and it is axially movably bonded in this fluid axial passage 12, and is kept putting in place by taper spring 48.The diameter of described pearl 47 is chosen as and does not enough enter into this container 2, and enough when the lower shoulder 43 of this pearl 47 and this contacts, forms sealing.

In unshowned embodiment, this spring can be vertical and be supported on this dipping tube 49(Fig. 8-Figure 11) upper, the inside diameter of this dipping tube is less than the diameter of pearl 47.

To the function of this dosage lid 100 be described below.

In position shown in Figure 9, this dosage lid 100 is arranged in blocking position, and the product wherein holding in this container 2 cannot be to this external container discharge.The tip of this obturating element 41 the 4th part 41d coordinates in the upstream of this fluid flow pass 13 and the narrowed portion 50 of this fluid axial passage 12.Described narrowed portion 50 has formed a kind of base, and the 4th part 41d can be supported on this base, thereby has guaranteed this fluid axial passage 12 of shutoff.

When this obturating element 41 mediates when middle, most advanced and sophisticated the 4th part 41d no longer coordinates with the narrowed portion 50 of this fluid axial passage.Therefore, realized a kind of part opening, this part opening can move axially the flow that described obturating element 41 controls and passes through by roughly unscrewing this plug members 40 with user by pressure fluid.The pointed shape of the 4th part 41d allows to open gradually.

In order to adjust this fluid according to the granularity of fluid to be allocated, flow out flow, the shape of the diameter of this third part 41c and this tip 41d can change.

In open position, the product holding in this container 2 is to these container 2 outside drain, because third part 41c no longer contacts the narrowed portion 50 of this fluid axial passage 12, thereby has the effect that destroys sealing.

When user unscrews this plug members 40, the bar of this obturating element 41 rises in this fluid axial passage 12.Still on the wall in being pressed against this fluid axial passage 12 described in close sealing member 46 and stopped progressive to operating element 42 of fluid.

Described pearl 47 has completed dual-use function: fill valve function and safety-valve function.This safety-valve function as shown in Figure 8.

In fact, in order to fill, this plug members 40 is non-existent, stops up this fluid flow pass 13, and pearl 47 is pressed to lower shoulder 43. by the contact between described pearl 47 and lower shoulder 43 by taper spring 48, has guaranteed leak tightness.

When filling, pressure enters fluid and to the inside of this container 2, presses described pearl 47, thereby this pearl 47 no longer contacts this lower shoulder 43, and allows pressure fluid to these container 2 inside.

This pearl 47 has played the effect of anti-rotation valve, this pearl has stopped the outflow that is contained in the fluid in this container 2, because press this pearl 47 these lower shoulders 43 of contact to the mobile fluid of outlet, formed leak tightness and organized the outside discharge of pressure fluid to this container 2.

This pearl 47 has also played the effect of safety-valve, because if this plug members 40 accidentally unscrewed, thereby this pearl 47 rises and again contacts this lower shoulder 43 and forms sealing.Therefore this pressure fluid is not towards the outside drain of this container 2.

Figure 10 and Figure 11 show the third embodiment of the present invention.Difference with respect to described the second embodiment is there is no taper spring.Pearl 48 is by this container 2(Figure 10) inner enough pressure keeps putting in place.

In Fig. 8-Figure 11, show a kind of dipping tube 49, for by fluid from the inside of this container 2 to exterior guiding.

After this dipping tube 49 of access, pearl 47 has the diameter that is greater than inside diameter, so that pearl 47 does not fall to this container 2(Figure 11) in.Thereby this pearl 47 is bonded between this dipping tube 49 and lower shoulder 43.

This dipping tube 49 does not illustrate in Fig. 1-Fig. 7, but it can design for completing especially the identical function of stroke of the described pearl 47 of restriction, or support the function of this spring 48.

In the embodiment of Fig. 8-Figure 11, the taper shape that preferably can design this needle-valve 41d has the angles of about 60 degree, and this needle-valve is intercepted can not damage described pearl 47 while contacting described pearl 47 with this needle-valve of box lunch 41d.

The described second and the 3rd embodiment is more particularly applicable to the fluid that granularity is less than 2 millimeters.

When this container must hold and distribute a kind of edible fluid, this dosage lid can be implemented by any material with edible feature.This dosage lid can for example, be implemented by plastic material or metal (corrosion-resistant steel or aluminum alloy).

This fluid egress point 13 can have the shape that dipping tube is adjusted in any permission, and described adjustment allows more to meet human engineering and distribute this fluid.

In unshowned embodiment, the cone angle alpha of the truncated cone of this outer radial periphery outshot 10 part does not also correspond to the angle of inclination beta of inward flange of the neck of this container.Therefore,, when rotation is during described insertion portion 9, formed vestige and this vestige has effectively stopped this main body.

In other embodiment of unshowned and embodiment based on Fig. 8-Figure 11, as required, pearl 47 can be replaced by the cylinder with the diameter of the interior diameter that is roughly less than the diameter of fluid axial passage 12 and is roughly greater than this spring 48.Described cylinder can be equipped roughly truncated cone shape groove, for example groove 22a(Fig. 6).Plug for seal part, as plug for seal part, 23a is arranged in this groove.Realized as shown in Figure 6 sealing, the narrowed portion of seal contacting with fluid axial passage, for example narrowed portion 50(Fig. 8-Figure 11).
