As shown in Figure 8, valve 36 comprises a center wall or 160 skirt section or the sleeve 164 that extend from valve.Thin annular lip 168 (Fig. 8) is arranged on the outer end of sleeve 164, starts when valve 36 is in, during quiescence, and described annular lip 168 is extended from sleeve 164 to the periphery with opposite direction of tilt.Thin annular lip 168 cooperates with amplification, thinner peripheral flange 170, and described peripheral flange 170 has the transversal profile (as shown in Figure 8) of approximate wedge shape.
In order to hold the bearing of valve 36 in nozzle 34, the top surface of wedge valve flange 170 has identical frusto-conical configuration and angle with the frusto-conical surface of nozzle or bearing 154.Other face of valve flange 170 (being the bottom surface) is by retaining ring 38 fixing (Fig. 8 and 9).Retaining ring 38 comprise outwards or inwardly over against, the annular clamping surface 172 (Fig. 8 and 9) of truncated cone, be used for engaging with certain angle the axial inside face (being the bottom surface) of valve flange 170, described angle matches with the angle of the adjacent inner surface of the wedge structure of valve flange 170.
The periphery of retaining ring 38 comprises outwards outstanding flange 178 (Fig. 8 and 9), is used for and annular pearl 142 snap-fit engagement (Fig. 8 and 13), and described annular pearl is inwardly outstanding in the inner radial of nozzle 34.When nozzle 34 was installed on the closure member pedestal 30, valve 36 inserted the bottom of opening of nozzle 34 together with retaining ring 38.When valve 36 was pushed through nozzle pearl 142, valve flange 170 and retaining ring 38 temporarily were out of shape, and valve flange 170 rests on the frusto-conical surface or bearing 154 of nozzle.Retaining ring 38 also can be pushed through and keep pearl 142, when retaining ring flange 178 passes and exceed nozzle pearl 142 with the generation snap-fit engagement, because in retaining ring 38 and/or nozzle 34, have enough flexibilities, to hold the parts of temporary transient elastic deformation, this snap-fit engagement presses valve flange 170 or press from both sides on the frusto-conical surface 154 that leans against nozzle (Fig. 8).This permission and valve cage 164 inside face adjacent areas freedom are fully opened without barrier, to adapt to the motion of valve cage 164, are described below.
(not shown) in the selection embodiment that considers, valve 36 are fit to be connected on the integral installation annex in the nozzle 34, perhaps remain in the nozzle 34 by the whole bag of tricks, and described method comprises forging, impression, gummed, ultrasonic welding etc.(not shown) in the selection embodiment of another consideration, closure member nozzle 34 can be molded, to form the roughly integral structure of rigidity, then valve 36 can dual injection molding in nozzle 34 (perhaps, can select to be molded in the exterior far-end of nozzle 34), and do not need to use retaining ring 38.
When valve 36 was installed in the nozzle 34 of the special shape shown in Fig. 8 and the 11-14, the center head 160 of valve 36 presented concavity in retaining ring 38.In a preferred embodiment, when valve 36 cut out, the outside face of the center head 160 of valve was lower than the clamping surface 154 of nozzle 34 in the center of seam 162 (Fig. 8).But, after lamina membranacea 28 is opened, as described below, subsequently, when the internal pressurization of package (generally also can be inverted) makes it pass through valve 36 to distribute composition, the center head 160 of valve is forced to from its concave position (shown in Figure 8) outwards towards the outer end of package and exceeds retaining ring 38, makes it more near the end of opening of nozzle 34, and valve 36 has just been opened like this.
For allocated product, at first open lamina membranacea 28, as described below, package is downward-sloping usually then, perhaps is inverted fully (if container 22 is extrusion pressing types, also can push).Squeeze receptacle 22 can push to increase pressure in the container 22 and make it externally on the environment atmospheric pressure.This forces product in the container 22 towards valve 36 and relative with valve 36, also force valve 36 towards outside extended position (for example from recessed or retracted position (shown in Figure 8), referenced patent US5,676, the position that stretches out of identical valve 46 among 289 Fig. 5 (it also shows valve in the withdrawal dead position shown in Fig. 5 dotted line, also shows valve extended position of opening shown in the solid line in Fig. 2-4)).The center head 160 of valve 36 to outer displacement can be by relative thin the motion of flexible sleeve 164 regulate.Described sleeve 164 moves to outside mobile pressing position from inside outstanding dead position, this just make sleeve 154 towards the outer end of package to outer itself " rolling ".
But after the center head 160 of valve outwards moved to enough extended positions, when internal pressure became enough high, the seam 162 of valve 36 was opened to distribute the stream material (not shown in FIG.).Described stream material is driven away by open seam 162 then or is discharged.
Shown in have in the extrusion pressing type package that covers 32 preferred form, the above-mentioned assign action of valve 36 generally only just occurs in the following cases: (1) lid 32 moves to open position (Fig. 7), (2) lamina membranacea 28 has been opened, as described below, (3) the downward-sloping or inversion of package, and (4) container 22 is extruded.When the pressure reduction between internal pressure and the external pressure reached a predetermined value, the pressure of valve 36 inboards was opened valve 36.Preferably, when affacting the inside of container 22 by will be enough big pressure boost (for example, by using enough power squeeze receptacles 22 (if container 22 is not a rigid container, when perhaps enough little pressure (as vacuum) being affacted nozzle 34 outside)), valve 36 is designed to only just open after passing the enough big pressure reduction of valve 36 effects.
Depend on the particular design of valve, when pressure reduction reduced, the valve of opening 36 can cut out subsequently, even perhaps pressure reduction is reduced to zero, valve 36 can stay open.In the preferred embodiment of the valve shown in the preferred embodiment of the system shown in Fig. 1-2 0 36, valve 36 is designed to can cut out when pressure reduction is reduced to or be lower than a predetermined value.Therefore, when the squeese pressure on acting on container 22 reduced, valve 36 cut out, and the center head 160 of valve is withdrawn into the recessed dead position in the nozzle 34.
Preferably, when container 22 was inverted fully, valve 36 was designed to bear valve 36 in-to-in fluid weights.Adopt this design, valve 36 cuts out if container 22 is inverted, but container 22 is not extruded, and the net weight of the flowing material on the valve 36 can not make valve 36 open so, perhaps stays open.In addition, open cover 32 and lamina membranacea 28 after, if the container 22 that shutoff valve 36 has been installed is owing to carelessness is tilted, product still can not flow out from valve 36, because valve 36 still keeps cutting out.
In a preferred embodiment, only when valve head 130 bore certain pressure reduction with the gradient direction effect, the lobe of valve 36 was outwards opened, and has wherein exceeded local environment pressure one predetermined value of valve head outside face at the pressure of valve head inside face.Product distributes by the valve of opening 36 then, is reduced to a predetermined value up to pressure reduction, and flap is closed then fully.
If the preferred form of valve 36 also is designed to enough flexible, to regulate the penetrating of ambient atmosphere, be described in detail below, opposite and when the pressure of valve head outside face exceeds pressure one predetermined value of valve head inside face, the flap of closing continues to move inward with permission valve 36 inwardly to be opened when differential pressure gradients then.
For some dispensing applications, require not only allocated product of valve 36, and penetrating (for example, the allowing squeeze receptacle (valve is installed on this container) to turn back to its original shape) of adjusting ambient atmosphere).By selecting to be used for the suitable material of valve arrangement, and suitable thickness, the shape and size of the each several part of the valve head 160 of the size of material by selecting to be used for particular usage valve and integral valve provide the penetrating ability of this ambient atmosphere.This valve head especially shape, flexibility and the elasticity of flap can design or determine, so that in the process of allocated product, when bearing the enough pressure reduction that passes valve head 160 and the gradient direction effect opposite or relative with the differential pressure gradients direction, flap is to intrinsic deflection.When the user discharges the elastic container 22 of the pressurized that valve 36 has been installed, can produce reverse pressure reduction.The elasticity of described wall of container makes wall return towards direction normal, the more volume structure.The increase in volume of internal tank can cause the reduction that internal pressure is temporary transient, of short duration.When internal pressure is reduced to when being lower than external environment condition pressure fully, the pressure reduction that passes valve 36 is enough to the intrinsic deflection flap, to allow the penetrating of ambient atmosphere.But, in some cases, needed penetrating speed or penetrating amount can not appear, turn back to the approximate vertical direction up to pressure-vessel, and in this direction, product is flowed towards container bottom away from valve 36.
The distribution openings that it should be understood that valve can limit by the structure of the seam 162 shown in being different from.If described mouthful limits by stitching, so according to these desired partition characteristics, seam can be supposed many different shapes, size and/or structure.For example mouth also can comprise five or more s' seam.
The product that distributing valve 36 is preferably configured as with special container and specific type uses, to obtain desired accurate partition characteristic.For example, according to shape, size and the intensity of container, the viscosity of fluid product and density can depend on the valve 36 of the special construction that is used for liquid.The size and dimension of the rigidity of the material of valve and hardness and valve head 160 also makes the characteristic of valve relevant with needed partition characteristic, and also matches with container and the material that distributes from this container.
Preferably, the inside of valve 36 and nozzle 34 all has the structure of circular, and valve 36 and nozzle 34 are along common longitudinal axis alignment.The center point of crossing of the seam 162 of valve is positioned on this longitudinal axis.Nozzle 34 is characterised in that along this to have axially outside outflow direction.
In preferred enforcement, when valve 36 opened and closed, the structure of nozzle arm 148 and disk 150 (Figure 13 and 14) was positioned on the valve 36 with protective valve 36.With reference to figure 7, the protection structure of arm 148 and disk 150 outwards is away from valve 36, thereby does not interfere the distribution of opening or can not influence stream material of valve 36.
Later-model closure system can be provided, and use with different types of valve (as mechanically activated valve), if perhaps requirement, without any need for valve.
The position of nozzle 34 in closure body or pedestal 30 helps stream material to carry out above-mentioned distribution by nozzle 34.Especially, with reference to figure 7, can be understood that, nozzle 34 to small part is arranged in the receiving cable in the pedestal 30, but the discharge end of the grasping of nozzle 34 is axially outwards outstanding from pedestal 30, to surpass the sealed engagement between the closure member pedestal sealing surface 62 on nozzle periphery sealing surface 108 and the ring seal flange 60.
As mentioned above, the nozzle 34 that valve 36 and retainer 38 be installed is initially attached to (as Fig. 1-7) on the closure member pedestal 30 with axial outside non-perforation position.The initial non-perforation position of nozzle 34 can limit (top that lamina membranacea or liner plate 28 have been sealed to container neck 26 in advance) easily with respect to the installation site subsequently of the complete closure part 20 on the container 22 of lamina membranacea or liner plate 28 tops, and wherein nozzle pierces through parts 120 and is positioned at lamina membranacea 28 tops.Before closure member 20 is installed, be full of after stream material is heat sealed on the container then at container 22, described lamina membranacea 28 is arranged on the container 22 at vessel filling pipeline place.If lamina membranacea 28 is the liner plate that comprises metal foil layer, this paper tinsel layer liner plate 28 can be heat sealed to container neck by known high-frequency heating or conduction.If liner plate 28 does not have metallic paper, also can use other thermal or adhesive agent method of attachment.
The non-perforation position place of the present invention in closure member pedestal 30 helps the installation of nozzle 34 (valve 36 and retaining ring 38 are installed on this nozzle 34), when crossing lamina membranacea 28 subsequently and screw on the containers 22 with convenient closure member 20, piercing through on the end face that parts 120 are initially at liner plate or lamina membranacea 28 of nozzle 34 separates.With reference to closure member pedestal 30 shown in Figure 10, it should be noted that with cam rail 70 in the upper end of each relevant axial location groove 71 contiguous cam rail 70 be provided with.In order to begin that nozzle 34 (comprising valve 36 and retaining ring 38) is installed, this nozzle 34 is positioned at the open top end of closure member pedestal 30, and nozzle 34 rotates on request then, to locate each nozzle cam follower 130 (Figure 11-14) in the direction of axially aligning groove 71.
In automatic assembling process, nozzle 34 (valve 36 and retaining ring 38 are installed on this nozzle) blocks by the conventional mounting chuck that is used for swivel nozzle 34, under the effect of suitable axial force (general spring assembly by axially loading produces) nozzle 34 is axially moved in the closure member pedestal 30 simultaneously.With reference to inverted closure member pedestal 30 shown in Figure 15, look down from Figure 15, nozzle 34 (valve 36 and retaining ring 38 are installed on this nozzle) with anti-clockwise rotation (adopting chuck for installing rotation or manually rotation automatically) to inverted closure member pedestal 30.The inhour rotation will make nozzle cam follower 130 (Figure 14) initially take along the annular end face 56 of inner sleeve 54 and put one arc lead-in surface 75 in each cam follower 130 arrival slot 71.Because axial force is applied on the swivel nozzle 34 (adopting chuck for installing rotation or manually rotation automatically) simultaneously, described cam follower 130 slides and enters in the groove 71 along lead-in surface 75.Stop at the other rotation of anticlockwise direction (looking down) vertical wall by each groove 71 relative with lead-in surface 75 from Figure 15.Automatically chuck for installing uses the rotary drive system of suitable torque limiting, in the time of in nozzle 34 axially pushes by the closure member pedestal 30 of the cam follower in the groove 71 130 guiding, this drive system stops will too much torsional interaction be out of shape or the damage parts avoiding to the nozzle 34.
When cam follower 130 arrives when inclined-plane 77 (Figure 15) is introduced in the radially inner extension at the place, end of each groove 71, each cam follower 130 77 is taken the upper end of putting and enter relevant track 70 along the inclined-plane.There are enough flexibilities in a lot of parts of nozzle 34 and/or a lot of parts of closure member pedestal 30, so that hold the temporary transient elastic deformation of nozzle 34 and/or closure member pedestal 30 q.s, slide and enter in the cam rail 70 to 77 tops, inclined-plane to allow cam follower 130.This set guarantees that nozzle 34 (valve 36 and retaining ring 38 are installed on this nozzle) initially is positioned at rising, the non-perforation position of closure member pedestal 30, when screwing on the container 22 subsequently with convenient closure member 20, the parts 120 that pierce through of nozzle initially are positioned at liner plate or lamina membranacea 28, as shown in Figure 8.
In addition, in preferred form of the present invention shown in Figure 10, the rotation that the rib 91 of contiguous each cam rail 70 can be designed to nozzle 34 provides certain resistance (in Fig. 2, regarding anticlockwise direction downwards as at the outer top of closure member pedestal 30 and nozzle 34).In Fig. 2, if the user regards anti-clockwise rotation nozzle 34 downwards as at the top of nozzle 34 and closure member pedestal 30, the initial resistance that provides by top rib 91 (Figure 10) must be provided so, when nozzle cam follower 130 passes rib 91, sense of touch and/or the clatter that can hear will indicate nozzle 34 away from rise fully, non-perforation position is rotated.Similarly, continue swivel nozzle 34 if the user regards anticlockwise direction downwards as from Fig. 2 on the top of nozzle 34 and closure member pedestal 30, nozzle cam follower 130 is in the last engage ribs in the lower end of cam rail 70 (Figure 10) so.When cam follower 130 passes bottom rib 92, pass with counter-clockwise hand of rotation then and when exceeding bottom rib 92, the user can hear the clatter that can hear, the user can continue to be further rotated, up to cam follower 130 in the lower end of the contiguous cam rail 70 of complete lower position of nozzle 34 (with respect to the most axial inside position of the nozzle 34 of closure member pedestal 30, in this position, if closure member 20 is installed on the container of lamina membranacea 28 tops, nozzle cutting part 120 is lower than the ascent direction of lamina membranacea 28 to be given prominence to significantly).
At first, when nozzle 34 when (the highest non-perforation position) inhour rotates to lower position shown in Figure 16-20 in the position shown in the figure 1 by the user, nozzle 34 and the parts 120 (Figure 19 and 20) that pierce through on it move down (axially inwardly), so that lamina membranacea 28 is pierced through by the tip 126 that each pierces through parts 120.When nozzle continues rotation to open lamina membranacea 28 (regard anticlockwise direction downwards as at the top of nozzle 34 and come swivel nozzle 34) by the user, look up from lamina membranacea 28, pierce through parts 120 and move with clockwise direction shown in Figure 20 from the inside of container 22.When each pierced through parts 120 and moves (Figure 20) with the form of circular arc, the tip 126 of piercing through parts 120 further axially inwardly moved in the lamina membranaceas 28, and passes lamina membranacea 28.Further axially inwardly move in the lamina membranacea 28 when piercing through parts 120, and when passing lamina membranacea 28, because each from most advanced and sophisticated 126 (for example pierces through parts 120, the end elevation of cutting part 120 shown in Figure 12) upwards (as axially outwards) increase on thickness along with the increase of distance, therefore become wideer by each width that pierces through perforation, tearing notch, otch or opening that parts 120 produce.Make the perforation of lamina membranacea 28 and the blade 190 in the notch shape film-forming plates 28 by each cutting part 120.Each blade 190 is narrower in its free distal end, becomes wideer away from free distal end.The width of blade is increased to maximum width, and this maximum width engages with the maximum width that pierces through parts 120 piercing through parts 120 tops, pierces through the remainder of parts 120 fit with nozzle 34.Shown in preferred embodiment in, when each pierced through parts 120 and moves through lamina membranacea 28 with curved path, each pierced through parts 120 and roughly " ploughed " blade 190 with the otch or the opening that exceed 45 oval arcs in the lamina membranacea 28.
Described blade 190 remains connected to the remainder of lamina membranacea 28, therefore can not produce independent waste fragment.Pierce through opening or tearing notch or the preferred long enough of otch that parts 120 form by lamina membranacea 28 interior each, so that extend through the length that pierces through parts 120 a little, thereby, stretch into and remain on the lower position that passes in a part of lamina membranacea 28 even pierce through parts 120b for the stream material that will distribute provides enough flow channels.Therefore, the user needn't just can make it turn back to the non-perforation position that rises fully by moving nozzle 34 with opposite direction distortion nozzle 34.Pierce through nozzle 34 and can stay lower position completely, and enough flowing can be pierced through otch, tearing notch or the open area of the lamina membranacea 28 of parts 120 rear ends by vicinity.
The Design of length of each cam rail 70 becomes to help to form sufficiently long opening in lamina membranacea 28, to regulate the distribution of stream material by the opening of lamina membranacea 28.High-viscosity material needs longer cam track device, so that longer arc gap or opening to be provided in lamina membranacea 28, thereby provides bigger flow region.More low-viscosity material does not need so long cam track device.Alternatively, perhaps in addition, the thickness on the top of cutting part 120 can increase, so that wideer otch or opening to be provided in lamina membranacea 28.
In a selectable design (not shown) of considering at present, only need to provide a cam rail 70.Rather than three cam rails 70.Also can provide more than three cam rails.It should be noted, in the alternate embodiments (not shown), use only cam follower, or more than three cam followers.But, in the preferred embodiment shown in Fig. 1-2 0, in closure member pedestal 30, use three cam rails 70, to hold three cam followers 130 on the nozzle 34, this set has been found that to have good balance and operation.It should be noted that also the position of cam rail 70 and cam follower 130 can be put upside down.That is to say, (not shown) in alternate embodiments, a cam rail or a plurality of cam rail can be arranged on the radially outer surface of nozzle 34, and a cam follower or a plurality of cam follower (as pin or other projection) can radially inwardly stretch into from the inner sleeve 54 of closure member pedestal in the track on the nozzle.
In the alternate embodiments (not shown) of considering at present, only be provided with one and pierce through parts 120.In other design, three or more can be set pierce through parts 120, rather than use shown in preferred embodiment in two parts.
With reference to figure 8, should be noted that, can stop nozzle 34 to be removed by overlapping engage of closure member base flange 60 with the amplification bottom 101 of nozzle 34 from closure member pedestal 30.In addition, in a preferred embodiment, wherein closure member pedestal 30 also is provided with at least one pawl teeth 50 (Figure 15), and with the counter-rotating ratchet 29A on the engagement container (Fig. 6 and 9), closure member 20 is not easy to remove by the user.Therefore, package is maintained fixed and disturbance rejection relatively.If someone twists nozzle 34 to pierce through lamina membranacea 28, rotate described nozzle 34 then and make it turn back to hoisting position, the user informs if pierce through lamina membranacea 28 by inverted container and/or squeeze receptacle subsequently, so that stream material can distribute.If stream material can distribute, the indication that provides a kind of lamina membranacea 28 to puncture in advance so.
In the preferred embodiment shown in Fig. 1-2 0, wherein pressure-activated valve 36 is installed in the nozzle 34, does not need to be provided with in some applications to cover 32.But, enter distributing nozzle 34 in order to make foul or other exterior materials, require basically to use and cover 32.
In an embodiment of the present invention, nozzle 34 is (if use retaining ring 38, just comprise valve 36 and retaining ring 38) and the parts (embodiment as Fig. 1-2 0 shown in) of closure member pedestal 30 for independently processing, these parts can quite easily be assembled by maker.
System of the present invention can be fit to use with package, wherein, the top that lamina membranacea 28 is sealed to the top of container 22 and crosses container 22, and the selectable design of adopting other, lamina membranacea 28 can be fixed to the below of closure member pedestal 30, rather than the top of container 22, perhaps be fixed to the top of container 22 in addition.
When the present invention uses selectable valve 36 when (as in the preferred embodiment shown in Fig. 1-2 0), valve 36 provides additional advantage, for example, if the prevention stream material overflows when the package of opening tilts owing to carelessness.In addition, valve 36 can provide other control (if do not get rid of, be included in assigning process and stop making afterwards the drippage minimum of fluent material from nozzle 34 by the user) to assigning process.Valve 36 also can play entering of destroy contaminants or make pollutants reduce to minimum.
Distribution closure system of the present invention is fit to use lamina membranacea 28, as traditional liner plate, and does not need to remove liner plate from container or system.Distribution closure system of the present invention allows the user to open lamina membranacea 28 (as traditional liner plate 28) easily, and does not need to operate package at first to expose lamina membranacea, does not also need lamina membranacea itself is removed.After lamina membranacea or liner plate are pierced, still remain in the system, so that it can not cause messy problem or the problem of suffocating to child.
Can there be various other change and modifications in understanding easily from the embodiment shown in foregoing detailed description of the present invention and its, and does not break away from the true spirit and the scope of novel theory of the present invention or principle.
