Valve 36 is fit to be installed in theclosure member nozzle 34, and is as shown in Figure 8.The preferred form ofvalve 36 is pressure-activated, flexible long and narrow type valve, and it remains on the inside ofnozzle 34 through retainingring 34, is described in detail as follows.

Valve 36 preferably is molded as integral structure from the material of flexibility, that be prone to bend, elastomeric and bounce-back.This material can comprise elastic body, as comprises that the synthetic thermosetting polymer of silaatic, said silaatic can be that U.S.'s brand name of selling through Dow Corning Corp is the silaatic of D.C.99-595-HC.Another suitable silastic material is the silaatic of Wacker 3003-40 by U.S.'s brand name that Wacker SiliconeCompany sells.These two kinds of silaatics have Xiao A hardness 40.Valve 36 also can be from other thermoset material or other elastomeric material or molded from thermoplastic polymer or thermoplastic elastomer; Said thermoplastic polymer or thermoplastic elastomer be with thermoplastic propene, ethene, urethanes and styrene, and comprise that their cooresponding halide is basis material.

Shown in preferred embodiment in,valve 36 has patent US5, the structure and the character of operation of disclosed and commercial available valve in 676,289, referenced patent US5, disclosedvalve 46 in 676,289.The operation of such valve is referenced patent US5, and the valve-like in 409,144 further describes.These two patents be described in this as a reference, and these two patents are relevant with consistent on degree.

Valve 36 is flexible, and changes structure between the movable open position (not shown) in the dead position (closed condition in the vertical type package shown in Figure 10 and 11) of closing in (1) and (2).Valve 36 comprises flexible core or 160 (Fig. 8 and 10).Whenvalve 36 was not activated, 160 had recessed structure (from the visual observation ofclosure member nozzle 34).160 preferably have two isometric, orthogonal, the plane, as to intersectdistribution seams 162, and the dispensing orifice that common qualification is closed is usually stitched in said distribution.Four of the qualifications in recessedcenter head 160 of theseam 162 of said intersection are roughly fan-shaped, the blade or the lobe of equidimension.When pressure reduction was enough big, said paddle response was passed pressure reduction thatvalve 36 increases and is outwards opened from stitching 162 point of crossing, at patent US5, was described in a well-known manner in409,144.Valve 36 can be molded with seam 162.Alternatively, theseam 162 of valve is cut in thecenter head 160 ofvalve 36 through suitable conventional art subsequently.

As shown in Figure 8,valve 36 comprises from the skirt section or thesleeve 164 of the center wall of valve or 160 extension.Thin annular flange flange 168 (Fig. 8) is arranged on the outer end ofsleeve 164, starts whenvalve 36 is in, during quiescence, and saidannular flange flange 168 is extended fromsleeve 164 with opposite direction of tilt to the periphery.Thinannular flange flange 168 cooperates with theperipheral flange 170 that amplifies, more approach, and saidperipheral flange 170 has the transversal profile (as shown in Figure 8) of approximate wedge shape.

In order innozzle 34, to hold the bearing ofvalve 36, the top surface ofwedge 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 through retainingring 38 fixing (Fig. 8 and 9).Retainingring 38 comprise outwards or inwardly over against, the annular clamping surface 172 (Fig. 8 and 9) of truncated cone; Be used for the axial inside face (being the bottom surface) with certainangles valve flange 170, said angle matches with the angle of the adjacent inner surface of the wedge structure ofvalve flange 170.

The periphery of retainingring 38 comprises outwards outstanding flange 178 (Fig. 8 and 9), is used for andannular pearl 142 snap-fit engagement (Fig. 8 and 13), and said annular pearl is inwardly outstanding in the inner radial of nozzle 34.Be installed in 30 last times of closure member pedestal atnozzle 34,valve 36 inserts the bottom of opening ofnozzle 34 together with retaining ring 38.Whenvalve 36 was pushed throughnozzle pearl 142,valve flange 170 temporarily was out of shape with retainingring 38, andvalve flange 170 rests on the frusto-conical surface or bearing 154 ofnozzle.Retaining ring 38 also can be pushed through and keeppearl 142; When retainingring flange 178 passes and exceednozzle pearl 142 with the generation snap-fit engagement; Because in retainingring 38 and/ornozzle 34, have enough flexibilities; To hold the parts of temporary transient elastic deformation, this snap-fit engagement pressesvalve flange 170 or press from both sides on the frusto-conical surface 154 that leans against nozzle (Fig. 8).This permission andvalve cage 164 inside face adjacent areas freedom are fully opened without barrier, to adapt to the motion ofvalve cage 164, describe below.

(not shown) in the selection embodiment that considers,valve 36 are fit to be connected on the integral installation annex in thenozzle 34, perhaps remain in thenozzle 34 through the whole bag of tricks, and said 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, thenvalve 36 can dual injection molding in nozzle 34 (perhaps; Can select to be molded in the exterior far-end of nozzle 34), and need not use retainingring 38.

Whenvalve 36 was installed in thenozzle 34 of the special shape shown in Fig. 8 and the 11-14, thecenter head 160 ofvalve 36 presented concavity in retaining ring 38.In a preferred embodiment, whenvalve 36 cut out, the outside face of thecenter head 160 of valve was lower than the clampingsurface 154 ofnozzle 34 in the center of seam 162 (Fig. 8).But; After laminamembranacea 28 is opened, be described below, subsequently; When the internal pressurization of package (generally also can be inverted) makes it pass throughvalve 36 to distribute composition; Thecenter head 160 of valve is forced to from its concave position (shown in Figure 8) outwards towards the outer end of package and exceeds retainingring 38, makes it more near the end of opening ofnozzle 34, andvalve 36 has just been opened like this.

For allocated product, at firstopen lamina membranacea 28, be described below, package is downward-sloping usually then, perhaps is inverted fully (ifcontainer 22 is extrusion pressing types, also can push).Squeeze receptacle 22 can push to increase pressure in thecontainer 22 and make it externally on the environment atmospheric pressure.This forces product in thecontainer 22 towardsvalve 36 and relative withvalve 36; Also forcevalve 36 towards outside extended position (for example from recessed or retracted position (shown in Figure 8); Referenced patent US5; The position that stretches out ofidentical valve 46 among 676,289 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)).Thecenter head 160 ofvalve 36 to outer displacement can be through relative thin the motion offlexible sleeve 164 regulate.Saidsleeve 164 moves to outside mobile pressing position from inside outstanding dead position, this just makesleeve 154 towards the outer end of package to outer itself " rolling ".

But after thecenter head 160 of valve outwards moved to enough extended positions, when internal pressure became enough high, theseam 162 ofvalve 36 was opened to distribute the stream material (not shown in FIG.).Said stream material is driven away throughopen 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 ofvalve 36 generally only just occurs under following situation: (1)lid 32 moves to open position (Fig. 7); (2)lamina membranacea 28 has been opened; Be described below, the downward-sloping or inversion of (3) package, and (4)container 22 is extruded.When the pressure reduction between internal pressure and the external pressure reached a predetermined value,valve 36 inboard pressure were opened valve 36.Preferably; When affacting the inside ofcontainer 22 through will be enough big pressure boost (for example; Through using enough power squeeze receptacles 22 (ifcontainer 22 is not a rigid container; When perhaps enough little pressure (like vacuum) being affactednozzle 34 outside)),valve 36 is designed to only after passing the enough big pressure reduction ofvalve 36 effects, just open.

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 when pressure reduction is reduced to or be lower than a predetermined value, can cut out.Therefore, when the squeese pressure on acting oncontainer 22 reduced,valve 36 cut out, and thecenter head 160 of valve is withdrawn into the recessed dead position in thenozzle 34.

Preferably, whencontainer 22 was inverted fully,valve 36 was designed to bearvalve 36 in-to-in fluid weights.Adopt this design,valve 36 cuts out ifcontainer 22 is inverted, butcontainer 22 is not extruded, and the net weight of the flowing material on thevalve 36 can not makevalve 36 open so, perhaps stays open.In addition,open cover 32 withlamina membranacea 28 after, if thecontainer 22 thatshutoff valve 36 has been installed is because carelessness is tilted, product still can be fromvalve 36 outflows, becausevalve 36 still keeps shut.

In a preferred embodiment, only whenvalve head 130 bore the certain pressure reduction with the gradient direction effect, the lobe ofvalve 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 through 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 ofvalve 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 withpermission 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).Through 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 through 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 confirm; So that in the process of allocated product; When bearing the enough pressure reduction that passes valve head 160 and the gradient direction effect in the opposite direction or relative with differential pressure gradients, 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 differential.The elasticity of said 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 through the structure of theseam 162 shown in being different from.If said mouthful limits through 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.

Distributingvalve 36 preferable configuration one-tenth use with the product of special container and specific type, 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 thevalve 36 of the special construction that is used for liquid.The size and dimension of the rigidity of the material of valve and hardness andvalve head 160 also makes the characteristic of valve relevant with needed partition characteristic, and also matches with container and the material that from this container, distributes.

Preferably, the inside ofvalve 36 andnozzle 34 all has the structure of circular, andvalve 36 aligns along the common longitudinal axis with nozzle 34.The center point of crossing of theseam 162 of valve is positioned on thislongitudinal axis.Nozzle 34 is characterised in that along this to have axially outside outflow direction.

In preferred enforcement, whenvalve 36 opened and closed, the structure ofnozzle arm 148 and disk 150 (Figure 13 and 14) was positioned on thevalve 36 with protective valve 36.With reference to figure 7, the protection structure ofarm 148 anddisk 150 outwards is away fromvalve 36, thereby does not interfere the distribution of opening or can not influence stream material ofvalve 36.

Later-model closure system can be provided, and use with different types of valve (like mechanically activated valve), if perhaps requirement, without any need for valve.

The position ofnozzle 34 in closure body orpedestal 30 helps stream material to carry out above-mentioned distribution through nozzle 34.Especially; With reference to figure 7; Can be understood that;Nozzle 34 part at least is arranged in the receiving cable in thepedestal 30, but the discharge end of the grasping ofnozzle 34 is axially outwards outstanding frompedestal 30, to surpass the sealed engagement between the closure memberpedestal sealing surface 62 on nozzleperiphery sealing surface 108 and thering seal flange 60.

As stated, thenozzle 34 ofvalve 36 andretainer 38 being installed is initially attached to (like Fig. 1-7) on theclosure member pedestal 30 with axial outside non-perforation position.The initial non-perforation position ofnozzle 34 can limit (top that lamina membranacea orliner plate 28 have been sealed tocontainer neck 26 in advance) easily with respect to the installation site subsequently of thecomplete closure part 20 on thecontainer 22 of lamina membranacea orliner plate 28 tops, and wherein nozzle pierces throughparts 120 and is positioned atlamina membranacea 28 tops.Beforeclosure member 20 is installed, be full of after stream material is heat sealed on the container then atcontainer 22, saidlamina membranacea 28 is arranged on thecontainer 22 at vessel filling pipeline place.If lamina membranacea 28 is the liner plate that comprises metal foil layer, this paper tinsellayer liner plate 28 can be heat sealed to container neck through known high-frequency heating or conduction.Ifliner 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 inclosure member pedestal 30 helps the installation of nozzle 34 (valve 36 is installed on thisnozzle 34 with retaining ring 38); Cross lamina membranacea 28 subsequently withconvenient closure member 20 and screw in 22 last times of containers, piercing through on the end face thatparts 120 are initially at liner plate or lamina membranacea 28 ofnozzle 34 separates.With reference toclosure member pedestal 30 shown in Figure 10, it should be noted that withcam rail 70 in the upper end of each relevantaxial location groove 71contiguous cam rail 70 be provided with.In order to begin that nozzle 34 (comprisingvalve 36 and retaining ring 38) is installed, thisnozzle 34 is positioned at the open top end ofclosure member pedestal 30, andnozzle 34 rotates on request then, to axially align direction location each nozzle cam follower 130 (Figure 11-14) ofgroove 71.

In automatic assembling process; Nozzle 34 (valve 36 is installed on this nozzle with retaining ring 38) blocks through the conventional mounting chuck that is used for swivel nozzle 34, and the while axially moves into nozzle 34 in the closure member pedestals 30 under the effect of suitable axial force (general spring assembly generation through axially loading).With reference to inverted closure member pedestal 30 shown in Figure 15, look down from Figure 15, nozzle 34 (valve 36 is installed on this nozzle with retaining ring 38) 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 to (automatic rotation of employing chuck for installing or manually rotation) on the swivel nozzle 34 simultaneously, said cam follower 130 is along in lead-in surface 75 slips and the entering groove 71.The vertical wall of crossing each groove 71 relative with lead-in surface 75 in the other rotating tee of anticlockwise direction (looking down from Figure 15) stops.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 130 guiding of the cam follower in the groove 71, this drive system stops perhaps damages parts to avoid being out of shape with too much torsional interaction to nozzle 34.

Whencam follower 130 arrives when inclined-plane 77 (Figure 15) is introduced in the radially inner extension at the place, end of eachgroove 71, eachcam follower 130 77 is taken the upper end of putting and get intorelevant track 70 along the inclined-plane.There are enough flexibilities in a lot of parts ofnozzle 34 and/or a lot of parts ofclosure member pedestal 30; So that hold the temporary transient elastic deformation ofnozzle 34 and/orclosure member pedestal 30 q.s, to allowcam follower 130 in slip of 77 tops, inclined-plane and entering cam rail 70.This set guarantees that nozzle 34 (valve 36 is installed on this nozzle with retaining ring 38) initially is positioned at rising, the non-perforation position ofclosure member pedestal 30; Screw in 22 last times of container subsequently withconvenient closure member 20; Theparts 120 that pierce through of nozzle initially are positioned at liner plate orlamina membranacea 28, and are 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; Must overcome the initial resistance that provides through top rib 91 (Figure 10) 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, so nozzle cam follower 130 in the lower end of cam rail 70 last engage ribs (Figure 10).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 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).

Closure member 20 with initially be positioned at after that rise, non-perforation position fullynozzle 34 assembles exactly,closure member 20 is spun on and is full of stream material and by the top of liner plate (like lamina membranacea 28) leak free container (like container 22).

Operation closure member 20 can be described with reference to accompanying drawing to open bylamina membranacea 28 leak free containers below.Thenozzle 34 that Fig. 1 and 8 shows inclosure member 20 is in initial installation direction; Whereinnozzle 34 is in maximum position of rising (promptly with respect toclosure member pedestal 30; The most outside position), wherein pierce throughparts 120 away from (as on)lamina membranacea 28 is in their positions farthest.On the other hand, Figure 17 and 18 shows with respect toclosure member pedestal 30 and is in the most inwardlynozzle 34 of position.

At first; When nozzle 34 through user (the highest non-perforation position) when inhour rotates to the lower position shown in Figure 16-20 in the position shown in the figure 1; 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) through 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 through 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.

Said 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 thatparts 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 movingnozzle 34 with opposite direction distortion nozzle 34.Pierce throughnozzle 34 and can stay lower position completely, and enough flowing can be pierced through otch, tearing notch or the open area of thelamina membranacea 28 ofparts 120 rear ends through vicinity.

The Design of length of eachcam rail 70 becomes to help inlamina membranacea 28, to form sufficiently long opening, to regulate the distribution of stream material through the opening of lamina membranacea 28.High-viscosity material needs longer cam track device, so that longer arc gap or opening to be provided inlamina membranacea 28, thereby bigger flow region is provided.More low-viscosity material does not need so long cam track device.Alternatively, perhaps in addition, the thickness on the top of cuttingpart 120 can increase, so that wideer otch or opening to be provided inlamina membranacea 28.

In a selectable design (not shown) of considering at present, acam rail 70 only need be provided.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, inclosure member pedestal 30, use threecam rails 70, to hold threecam followers 130 on thenozzle 34, this set has been found that to have good balance and operation.It should be noted that also the position ofcam rail 70 andcam 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 ofnozzle 34, and a cam follower or a plurality of cam follower (like pin or other projection) can radially inwardly stretch in the track on the nozzle from theinner sleeve 54 of closure member pedestal.

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 throughparts 120, rather than use shown in preferred embodiment in two parts.

With reference to figure 8, should be noted that, can stopnozzle 34 to be removed through overlapping engage of closuremember base flange 60 with theamplification bottom 101 ofnozzle 34 from closure member pedestal 30.In addition, in a preferred embodiment, whereinclosure member pedestal 30 also is provided with at least one pawl teeth 50 (Figure 15), and with thecounter-rotating ratchet 29A on the engagement container (Fig. 6 and 9),closure member 20 is not easy to remove through the user.Therefore, package keeps fixing also disturbance rejection relatively.If someone twistsnozzle 34 to pierce throughlamina membranacea 28, rotate saidnozzle 34 then and make it turn back to hoisting position, the user informs if pierce throughlamina membranacea 28 through 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-activatedvalve 36 is installed in thenozzle 34, need not be provided with in some applications and cover 32.But, get into distributingnozzle 34 in order to make foul or other exterior materials, require basically to use andcover 32.

Nozzle 34 in closure system of the present invention can be easily pierces through thelamina membranacea 28 of initial setting up such as (as puncture, isolate, break off, tear, cutting) at correct position with operation effectively, thus the integraty of the stream material that keeps discharging.Before exhaust constituent, closure system does not need whole removing to remove single parts (like lamina membranacea 28), thus the possibility that the vitals of elimination distribution system is lost.

In an embodiment of the present invention, nozzle 34 (ifuse retaining ring 38, just comprisingvalve 36 and retaining ring 38) andclosure member pedestal 30 are the parts (embodiment shown in Fig. 1-2 0) of independent processing, and these parts can quite easily be assembled through 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 ofcontainer 22 and crossescontainer 22, and the selectable design of adopting other, lamina membranacea 28 can be fixed to the below ofclosure member pedestal 30; Rather than the top ofcontainer 22, perhaps be fixed to the top ofcontainer 22 in addition.

When the present invention usesselectable 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 fromnozzle 34 through the user) to assigningprocess.Valve 36 also can play the entering of destroy contaminants or make pollutants reduce to minimum.

Distribution closure system of the present invention is fit to uselamina membranacea 28, like traditional liner plate, and need from container or system, not remove liner plate.Distribution closure system of the present invention allows the user to open lamina membranacea 28 (like traditional liner plate 28) easily, and need not operate package at first to expose lamina membranacea, also need lamina membranacea itself not 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.

Easily can there be various other change and modifications in understanding from above-mentioned detailed description of the present invention and the embodiment shown in it, and does not break away from the true spirit and the scope of novel theory of the present invention or principle.
