The specific embodiment

Fig. 1 shows the neck 10 of container.Generic container is with the suitable material injection blow molding container made of polyethylene terephthalate (PET) for example.Yet, should be noted that the present invention is applicable to the various forms of containers of being made by various materials.Neck 10 is included in the helical thread part 12 that forms on the outside face 14 of neck 10.Generally, threaded portion 12 forms on neck 10 with integral body.The adaptive engagement of helical thread part of complementation on the skirt shape part inside face of threaded portion 12 its screw threads and tamper-evident.

The annular pilfer that comprises neck 10 opens flange (bead) 16, and it is positioned at below the threaded portion, and radially protruding from the outside face of neck 10.Tamper-evident bead 16 preferably is moulded on the outside face of neck 10.The ridge that one or more separation separate stretches out downwards from flange 16, and it is around the periphery of neck 10.In an example, container neck 10 has the ridge 18 at four basic identical intervals.Ridge 18 is fit to be meshed with the little lappet (tab) of the tamper-evident band of closure member and impel described band to shake off closure member skirt shape part.

Fig. 3 is the cutaway view of tamper-evident 100, the container neck 10 shown in its adaptive Fig. 1.Describe closure member 100, describe it in the back and be applied to container 10.On general, closure member is the single-piece molded structure.Closure member 100 comprises upper wall 102 and the skirt shape part 104 of extending downwards.Closure member comprises the helical thread part 106 that is positioned on the skirt shape part inside face 108, corresponding helical thread part 12 adaptive engagements on the outside face of itself and container neck 10.Closure member comprises tamper-evident band 110 in addition, and its skirt shape part from closure member is extended downwards.The tamper-evident band is connected with the lower surface 112 of skirt shape part 104 by easily separated (frangible) part 114, and described easily separated part 114 is made of a series of rib that separates 116 along periphery, and described rib 116 by slit 118 separately.The cross section of rib 116 provides enough intensity can and/or use the exemplary force that closure member is transmitted in during container neck in operation to bear.The tamper-evident band comprises the wall 120 of annular, extends the little lappet 122 of a series of separation spacings from it.Little lappet 122 is connected by the lower surface of hinge fraction 124 with annular wall 120.At first, little lappet 122 inwardly radially extends with the obtuse angle with respect to the wall 120 of annular, to help the demoulding from the mould.After closure member is molded, little lappet 122 move into the annular wall 120 between be vertical or acute angle.Each little lappet 122 all comprises active flank 124, its at closure member from the process that container is removed, with the ridge 18 adaptive engagements on the container neck 10.

The sealing element 130 of annular stretches out downwards from the inside face of closure member upper wall 102.Sealing element 130 comprises the top 132 that periphery extends, and its inwall facing to container neck is placed, and provides sealing for container.Second sealing element 134 extends internally and extends downwards from upper wall 102 from wall 108, and it is meshed with the outside face 14 and/or the upper surface 15 of neck 10.

The structure of ridge 18 will be described in further detail now.Fig. 5 is the section drawing that the Y-Y plane is intercepted between Z-Z ' in Fig. 1, and it shows the profile of ridge 18, and Fig. 6 is the section drawing of the neck that the W-W plane is intercepted in Fig. 1, and it shows the optimum position of ridge 18 around the neck outer rim.For closure member is removed from container neck, closure member will rotate by anticlockwise direction, shown in arrow X among Fig. 6.

With reference to Fig. 5 and 6, ridge 18 is moulded on the outside face of neck, and it is positioned at the below of tamper-evident bead 16.Each ridge all comprises a series of, 18a, 18b and 18c.Face 18a has size J, and it is equal to or less than tamper-evident bead 16 and stretches out distance above the outside face of container neck.Face 18a be designed with closure member 100 on little lappet 122 mutual actions, make that when closure member rotated, the active flank 124 of little lappet 122 was meshed with angled active flank 18a.When closure member is further rotated, little lappet 120 is pushed down along angled 18a, thereby on frangible ribs 116, apply power and help frangible ribs 116 dialysis, thereby, impel the tamper-evident operation ahead of time by opening in the lower edge of skirt shape part 140 and the recognizable space between the tamper-evident band 110.

Fig. 2 has shown an alternative embodiment, and wherein face 18a comprises the part 18a ' that becomes angle changing with respect to the lower surface plane of tamper-evident bead 16.In one embodiment, this mask has the initial bending part, and its angle with respect to the lower surface of this flange increases gradually.This frangible ribs 116 that stretches and weaken gradually and progressively, make when the steeper part of the angle on the active flank 124 arrival face 18a of little lappet 122 on the tamper-evident band 110, frangible ribs 116 is fully weakened, and the further rotation of closure member is advanced to active flank 124 under the face 18m, impels frangible ribs to destroy thus.In an alternative (not shown), face 18a can comprise the discontinuous plane that two or more angles for tamper-evident bead 16 increase gradually.In this embodiment, face 18a has the initial surface that a plane with respect to the lower surface of tamper-evident bead 16 is angle, is thereafter the other surface that the plane angulation of one or more lower surfaces with respect to tamper-evident bead 16 increases gradually.

Fig. 4 has shown sealing arrangement, the outer wall sealed engagement of itself and container neck 10.

According to a further aspect in the invention, the distance between the face 18m of the following and ridge of container tamper-evident bead 16, and scope and the position of the 18a ' of sloping portion gradually of the face 18a of ridge, should consider when designing:

(i) when closure member is applied on the container fully, the distance in the representative gap between the active flank 124 of tamper-evident band 110 and tamper-evident bead 16 following.Promptly to consider active flank 124 and protrude relative position between the 18a ' of sloping portion gradually of object plane 18a, so that described active flank 124 contacts with the described 18a ' of sloping portion gradually with before the steeper part of angle of protruding object plane 18a contacts; With

(ii) frangible ribs 116 before dialysis vertically the distortion distance.

It shall yet further be noted that for specific container when closure member was applied on the container fully, possible was the relative position of determining in advance between closure member tamper-evident band 110 arbitrary portions and the ridge 18.

By the one or more frangible ribs that weakened 116 of selectivity design, can reduce to stretch at first and rupture the required power of first frangible ribs.Can pre-determine when removing closure member which frangible ribs and shift to ridge 18 at first, therefore the frangible ribs of described reduction is by advancing downwards and can be positioned along protruding object plane 18a, so that be stretched at first.

Face 18b has size K, it is at least greater than the width of the interval 122c between the mate 122 of tamper-evident band 110, so that the free end 126 of little lappet 122 be maintained at ridge 18 edge 18m below, thereby between tamper-evident band 110 that separates and closure member skirt shape part 104, form more significantly space.

Face 18c has the bevelled surface, with minimise interference when closure member is applied to container neck at first, and makes little lappet can easily pass through ridge.Should be noted that closure member can be designed to be employed with the axially movable mode (for example by using multiple-screw thread) rather than the mode of rotation.

Fig. 7 is the partial perspective cutaway view of a preferred embodiment of tamper-evident band 110 before being applied to container.Tamper-evident band 110 suspends by the lower surface (not shown) of a series of rib 116 from closure member skirt shape part, and described rib 116 has formed easily separated part.Described band comprises wall 120 and a plurality of little lappet 122 along peripheral intervals of annular, and described little lappet 122 is connected to the inside face of the wall of annular.Little lappet 122 extends by the lower surface of hinge portion 124 from the wall 118 of annular.Little lappet 122 stops this free end at the free end that comprises active flank 124.At first, little lappet 122 inwardly radially extends with the obtuse angle with respect to the wall 120 of annular, and curves inwardly along hinge 124 subsequently.

(not shown) in one embodiment, the active flank 124 of little lappet 122 has the angle corresponding to the dip plane 18a of ridge 18, makes that active flank 124 trends towards contacting with face 18a in its whole major part.This be easy to avoid face 124 and 124a joint curl or folding, thereby help guiding active flank 124a downward along dip plane 18a.

Preferably, one or more perforation 128 are set along hinge 124, thus the discharge that in filling process, allows to overflow material.

All be provided with groove 122a between each little lappet 122, it has width R and depth S.The degree of depth ' S ' is preferably, make that when closure member is applied to container the part that is present in the continuous circular shape of band fully is reduced to the bending that makes along the line of the base portion 122e of this groove 122a along the circumferential strength of the line that extends from the base portion 122e of groove 122a and can helps closure member more easily to be applied to container.

Preferably, the degree of depth of groove 122a ' S ' is greater than the distance between dotted line W and the X among Fig. 1, thereby the free end 124 that allows little lappet 122 is at least near inclination active flank 18a the time, keep next-door neighbour's container neck, and allow the free end of closure member active flank 124a to be meshed with bevelled active flank 18a.Along with the continuation of removing rotation, the free end of active flank 124a is pushed down along bevelled active flank 18a, thereby cause the axial stress on the frangible ribs 116, cause the destruction of one or more ribs, and impel tamper-evident band 110 to separate ahead of time from closure member 100.Strengthened the validity that contacts between described active flank 124a and the described bevelled active flank 18a by the position that helps to keep active flank 124a along the part of the continuous circular shape of the mate 122 of the tamper-evident band 110 of the line that extends from the base portion 122e of groove 122a.

When closure member is applied to container, the inwall of the relative tamper-evident band of shoulder promotes the tamper-evident bead mate 122 of tamper-evident band 110 on tamper-evident bead 16 bevelleds, make tamper-evident band 110 can pass through tamper-evident bead 16, and the free edge of the upper area of the inwall of the described relatively tamper-evident band 110 of dip plane 18c of ridge 18 promotion mate 122, make the mate of described tamper-evident band 110 can pass through ridge 18.

In the another one example of closure member tamper-evident band, at least four sizes that can have ' R ' size that is called as among the groove 122a of detent increases, and it is positioned so that when being applied to container neck fully, the center-point of each described detent is all roughly near each center of similar number (in this example being four) ridge, thereby makes to have the gap between arbitrary limit of some 18b at least of active flank 124 and ridge 18.In same example, little than described detent of at least four other ' R ' sizes of groove 122a, and it is little to connect that part of length of the lower surface 18m of face 18b of ridge 18 ideally near its ' R ' size.When removing rotation, active flank 124 contacts with described ridge 18, and promote downwards along face 18a, thereby be continuously applied axle pressure to most of at least frangible ribs 116, and separate most at least frangible ribs 116 substantially or fully, and tamper-evident band 110 is moved to the bottom of the lower surface 18m of ridge 18.Groove 122a with reduced size ' R ', rather than described detent, to pass through in the bottom of those parts of the lower surface 18m adjacent with the face 18b of ridge 18, thereby continue to apply lasting axial stress and basic separate frangible ribs 116, and tamper-evident band 110 with facilitate thus separating of closure member 100 ahead of time and more significantly open synchronously.

With reference to Figure 28, shown the part sectional view of container neck and closure member.Container neck comprises surreptitiously and opens (tamper) flange 16 that it has the lower surface that is positioned on the plane.According to a further aspect of the invention, design closure member according to following formula (formula A):

A≥B+C+D+E+F

Wherein:

(i) A is such distance, and at this distance range, sealing element can seal at the inwall or the outer wall (not showing in the example) of container neck;

(ii) B is when closure member is applied to container fully, the distance between the active flank 61 of tamper-evident bead 16 and the active flank 124 of little lappet 122;

(iii) C is during closure member is removed process, the amount of compression that is produced at the little lappet 122 of described tamper-evident band;

(iv) D removes in the process at closure member, the amount of tension that is produced when the frangible ribs 116 of skirt shape part and connection tamper-evident band 110 and closure member skirt shape part 104 is subjected to stress;

(v) E is such distance, and this distance equals the tolerance that allowed in the measurement explanation of container neck 10 and closure member 100;

(vi) F is the required distance of safety factor that is used for specific closure member and neck combination, operates before the sealing between closure member and the container neck loses to impel tamper evident device.

The number of degrees that dimensional units in the variable in the above-mentioned formula (formula A) is removed rotation with closure member are measured.This alternative formula can be used for having the tamper-evident system of the ridge 18 of type shown in Fig. 1 and 2.

Can design the each side of above-mentioned closure member invention and use as U.S. Patent No. 6,551, disclosed mold equipment and method are made among 093 and 6,640,988 (Taha), and the open of its is introduced in this specification sheets hereby.In a change scheme, shown in Fig. 7, the mate of tamper-evident band 110 can be moulded in position, make angle ' A ' between line A1 and the line A2 greater than 0 ° and less than 45 °, and its best is about 30 °, described line A1 extends and is parallel to it from the inwall of tamper-evident band 110, and described line A2 extends and is parallel to it from the outer wall of the annular mate 122 of tamper-evident band.

Fig. 6 is the cutaway view of container neck 10, and it has shown the optimum position (being represented by annular broken) that surreptitiously opens the inclination ridge 18 below the flange 16.A kind of manufacturing and the mould assembly method that are used to construct container neck are as follows:

Line V-V is the parting line of two mold components.Shown in Fig. 1 center line V1-V1, mould split line can be along by face 18a and 18b, or the path that the border indicated between 18b and the 18c is favourable, makes that the dip plane 18a in ridge 18-2 and 18-4 can be respectively at mold component Q at least ₃And Q ₁The middle shaping.

Angle between the leading edge of the ridge shown in ' F ' among Fig. 6 and the wall of neck is preferably 90 ° or littler.

In a two-part moudle, and a part of sectioned of passing through the container mould of structure neck and ridge 18, the parting line that has is the straight line of from 90 ° to 270 ° (3 o'clock, direction was to 9 o'clock direction), 0 ° is positioned at 12 o'clock direction, nominally so described cross section is divided into four equal quadrants, quadrant Q ₁With quadrant Q ₂All mould the first half in, and quadrant Q ₃With quadrant Q ₄Mould the second half in, Q wherein ₁Be positioned between 270 ° and 360 ° Q ₂Be positioned between 0 ° to 90 ° Q ₃Be positioned between 90 ° to 180 °, and Q ₄Be positioned between 180 ° to 270 °.

Only at quadrant Q ₁With quadrant Q ₃In, or they and quadrant Q ₂With quadrant Q ₄Between joint, face 18a can 90 ° or littler angle ' F ' and constructing.

The ridge 18 that is molded with face 18a can have the face with angle ' F ', and described angle ' F ' is successively decreased since 90 ° by 1 °, and each angle is all less than 359 °, similarly at quadrant Q ₃In be since 179 °, described 18a be built in from 270 ° to about 359 ° at quadrant Q ₁In (difference between 359 ° and 360 ° is represented " demoulding (draw) " required tolerance so that mould when opening and do not disturb face 18a at least).

Angle ' F ' has advantage less than 90 °, this is to rotate and when contacting with face 18a because remove when closure member, the free edge 124 of mate 122,124a will tend to inwardly pass face 18a and advance to neck wall 14, and thereby keep near face 18a, and container neck wall 14 trends are guaranteed to continue to move downward along face 18a.

Yet, be positioned at quadrant Q if ridge 18 is moulded to have by mold structure ₂And Q ₄In the surface (not being joint) of the 18a of face at least with quadrant 1 and 3, the angle ' F ' that has of face 18a will be greater than 90 ° so, this will produce not desired effects of institute when closure member is removed rotation, and tending to make the free edge 124 of mate 122,124a is away from wall of container 14 and through ridge 18.

It should be noted that, mould split line can depart from (disalignment, in described centerline, half of mould and other half mirror image) to adapt to the structure of one or two ridge 18, therefore half of mould can be protruded and pass " mirror image parting line " and enter generally by the second half of mould occupied spaces, and described mould the second half have corresponding shape to hold the first half of protrusion.

The most frequently used single screw thread closure member removing the operation from container, initial 90 ° that approximately remove rotation at least can not make closure member promote removing on the direction, and this is because at first there is cooresponding dimension limit difference between the matching thread of container and closure member.

One embodiment of the present of invention, container neck preferably has four and is equally spaced, or the ridge 18 that is equally spaced substantially, make in about closure member is removed the one 90 ° to 120 ° of rotation, most of free end 124 of mate contacts with described ridge with 124a, and promote downwards along face 18a, thereby apply the frangible bridges of axial force and basic or complete separating most, and make tamper-evident band 110 move to ridge 18 lower surface 18m below, realize ahead of time and appreciiable tamper-evident more.

An alternative embodiment of the invention, container neck preferably have two or more and are positioned at quadrant Q ₁And Q ₃Ridge 18, make angle ' F ' that all ridges 18 have all less than 90 °, or be equally spaced substantially, thereby in about closure member is removed the one 90 ° of rotation, most of free end 124 of mate contacts with described ridge with 124a, and promotes downwards along face 18a, thus the frangible bridges of separating most, and tamper-evident band 110 is moved to ridge 18 lower surface 18m below, realize ahead of time and appreciiable tamper-evident more.

The V1-V1 of parting line shown in Fig. 1 can be with shown different, and it still can realize the structure of described inclination ridge.

Container mould also can be the extended cavity type, and it has the part more than two, thereby allows molded at least one ridge 18 on each part of extended cavity mould.

Now with reference to Fig. 7 a the molded of closure member shown in Fig. 4 100 described.Following is molded order of steps.According to the profile of hole sealing member (bore seal) 130, core (core) 4 moves according to the direction of arrow, to discharge in-to-in hole sealing member 130.Yet, should be noted that profile according to hole sealing member 130, core 4 can move.Outer core sleeve also moves according to same direction, to discharge the outside of tamper-evident band 110.

Stripper ring (stripper ring) 22, ejector sleeve 5 and interior core 6 move according to opposite direction.When the end of moving, closure member 100 breaks away from thread core 3, and hole sealing member 130 also leaves thread core 3 fully.Inner sleeve 42 also breaks away from the front surface of core 4.At this moment, interior core 6 and stripper 21 are braked.Ejector sleeve 5 further promotes forward subsequently, thereby causes interior barrel 42 to be pushed away interior core 6, and the outside of tamper-evident ring 110 is pushed to the outside of stripper ring 22.When core 4 tube 42 disengagings fully internally, undercut (undercut) 44 can freely pass through interior core 6.

Fig. 8 to 11 shows other one side of the present invention.This aspect is equipped with apparatus for filling for the container-closure that preferably has tamper evident device, and this apparatus for filling will comprise within it the container that one or more additives are filled into closure member is connected.The advantage of described apparatus for filling comprises the material isolation that can keep in additive and air and the container, when the user uses.

Fig. 8 has shown closure member 100, and it has upper wall 20, and described upper wall 20 has the circular open 22 of the diameter " P " that forms therein.The circumferential surface of opening 22 is provided with one or more circumferential ribs.

After additive was added in the injection container, cover cap 224 can be removed, thereby the material in the container passes through the open end circulation of piston actuater cylinder 226, and can easily be obtained by the user.

Figure 12 to 15 illustrates another aspect of the present invention.Figure 12 has shown the cross-sectional view strength of closure member and container neck.Closure member 100 has upper wall 102, and this upper wall 102 has the annular skirt part 104 that suspends, and described skirt shape partly has screw thread 106, and respective threads 12 is suitable on itself and the container neck.Closure member can randomly comprise the tamper-evident band 110 of annular.Apparatus for filling core 208 is manufactured to the part of closure member 100, it extends above the upper surface 11 of upper wall 20, and have a plurality of filling lid lift slopes 209, filling and cover falling ramp 201, annular wall 207, positioning function part 202, on casing string 205, have wall 206 and casing string strut member 203.

Figure 13 has shown the transversal surface that passes closure member 100 centers, and it has bevelled filling lid 300 and tamper-evident cover 400.The taper filling is covered 300 and is had sealing function part 301.A plurality of grooves 304 on lid 300 outside face provide annular knurl processing (knurled finish), with close and open position between rotation filling when covering, in order to the part of holding with a firm grip to be provided.Between opening and closing moving period of filling lid, wall 207 sealing contacts of sealing function part 302 and complementary annular, thus provide sealing 204 to leak from the aperture along wall 207 with the material that prevents container.Sealing function part 302 is retrained by positioning function parts 202.

Lift slope engagement capability part (not shown) is meshed with lift slope 209, and when the direction rotation is opened on filling lid edge, it will be annotated and cover 300 and rise to open position, and closing when rotation, and close the inclined-plane and cooperates 201 annular to close engagement capability part 303 to cause the filling lid mobile along closing direction ' C '.

The diameter ' K ' in the aperture 305 of annular is less than the external diameter of pipe box post 205, make when when closing contrarotation, sealing function part 301 and wall 206 sealed engagement, thus provide container contents definitely with air seal.

Annular base 306 has the shaped region (not shown) on its outer wall 307, it is meshed with function corresponding part (not shown) on cover 400 the inwall 405, makes the rotation of described cover will cause the rotation of described annular base.

Tamper-evident cover 400 has circular top wall 403.The skirt shape part of annular suspends from described upper wall, and described skirt shape partly has engagement capability part 401, and it is annular ring or comprise independent funtion part more than 1.A funtion part or a plurality of funtion part are meshed with the upper surface that 300 annular base 306 is covered in filling, thereby cover is positioned on the annular base.

Inwall 405 can have the shaped region (not shown), and it is meshed with the function corresponding part (not shown) that filling is covered on 300 outer walls 307, covers 300 locking mesh so that cover 400 and filling to be provided.In alternatives shown in Figure 15, cover 400 also can be positioned by the groove of one or more ridges that is complementary on annular base 306 and lower wall 408 and/or coupling or cover 300 locking meshes with filling.The ridge on the annular base 306 and the label of groove are 308 and 309, and its label is 409 and 410 on lower wall 408.

Have more than one frangible bridges 402 annular that suspends from it or other tamper-evident band or device (not shown), it partly is meshed with function corresponding as 13 and 14 place display types on the upper wall 20.

As an alternatives of shaping inwall 405, cover 400 also can cover 300 locking meshes with filling after the tamper-evident features part operation, can suspend more than location meshing flake (fin) 407 (dotted line and shades) from upper wall 403, and it is meshed with groove 304.Described engagement spacer can be constructed on the inwall of cylinder shaped portion 406 (dotted line), and it suspends from upper wall 403.

Figure 14 illustrates the birds-eye view of closure member 100, and it comprises top wall surface 11, falling ramp 201, pipe box post support 203, aperture 204, pipe box post 205 and lift slope 209.

Figure 15 illustrates the cross-sectional view strength of cover 400, tamper evident device (comprise not show known devices) from the lower end of wall 404 for example after frangible bridges 402 is separated, geared assembly 409,410, geared assembly 308,309 covers 300 with filling and is meshed.By catching and rotary cover, engagement or locking mesh device are intended to allow filling to cover 30 to rotate to open position from off position, and rotate to off position from open position, and, primary described rotating to when opening, by cover 400 axial motion simultaneously tamper evident device be limited in ridge or the groove located as 13 and 14 (Figure 13) on the upper wall 102 (among Figure 12) and be meshed, and/or lifter motion annotate simultaneously the lid be meshed with lift slope (209 among Figure 12), thereby, cause and separate frangible bridges 402.

Figure 15 has also shown other or alternative geared assembly 412, cover 300 with engagement or location or lock cover 400 and filling, the diameter of design upper wall 403 surpasses the wall 404 that suspends, thereby expectation set packing with by gravity with container in material when discharge in the filling aperture, the diameter of upper wall 403 can increase to provide more firm, is used for placing the base portion of packing thereon.

Therefore Figure 16 has shown the partial cross-section of alternative filling closure member, and it is simplified, and has less parts, and thereby has a lower manufacturing cost.

Closure member 100 combines apparatus for filling 20, and it has the filling aperture 22 of annular.The filling aperture 22 of annular by with tamper-evident seal closure 40 on cooperating of sealing arrangement 42 of annular and sealed.

Tamper-evident seal closure 40 can be arbitrary shape, and for example accurately according to such shape of filling part 20 shapes, and/or it can be fixed to closure member locating in position except shown in tamper-evident band 110 positions.For example tamper-evident band 110 can be located in filling part 20.

When the tamper-evident seal closure was removed rotation, easily separated part 114 was separated, and described easily separated part is used for tamper-evident band 110 is fixed to the wall of tamper-evident seal closure.Tamper-evident band 110 has geared assembly with restrict removal rotation and impel frangible bridges to break.

After opening for the first time, tamper-evident seal closure 40 can be fixed on the closure body once more by annular ridge 47, and described annular ridge 47 matches with annular engagement ridge 123 and locatees and fixing tamper-evident seal closure 40.

Closure member 100 can be produced by the die assembly of disclosed type among Figure 16, and mode is for revising the shape of the closure member part above the upper wall annular disk 102, with the shape of the filling part 120 of structure hollow.

Expectation can make the diameter in filling aperture 22 less or bigger according to the viscosity of the material of waiting to annotate and the grain size that is comprised.Figure 18 illustrates opening arrangement 630, itself and filling part 20 locking meshes.Opening arrangement can have the annular orifice of the diameter of any desired shown in label 31,32 and 33.Opening arrangement matches with annular seal 542, with airtight container.Advantageously, use opening arrangement 630 can allow a kind of closure member product of size just to satisfy various filling demands.This has produced such benefit, makes just can hold all port sizes with the closure mould in big chamber, and has cooresponding cost efficiency.

Advantageously, if fixed orifice device 630 after filling with, can reduce so and be used for the needed closure member bracing frame (stockholding) of user with the filling closure member in different size filling aperture, this is because the user only has a closure member size, and little many orifice variation devices of different size are but arranged.

In an alternative described in Figure 17, the obstructed overwinding of closure member transfers opening and closing.In this embodiment, closure member opens and closes by removing and/or replace tamper-evident seal closure 540.Seal closure 540 has the sealing arrangement 542 of annular, itself and annular orifice 22 engagements at filling part 20 places of closure member 100.Tamper-evident ring 543 is connected with cover wall 546 by frangible bridges 545.

The manufacturing of the closure member shown in Figure 12 to 15 is described now with reference to Figure 16.Figure 16 has shown the cross-sectional plane of the die apparatus that is used to make filling closure member 100.Die apparatus is characterized as the stripper ring 1C of annular, and it is fixed on the plate 1, and it forms lower surface, frangible ribs 116 and the part tamper-evident band 110 of wall 30.Described equipment also is characterized as outside core 2C, and it is fixed on the plate 2, and it forms portion of external wall and surreptitiously opens lower surface with 110, surreptitiously opens the outer wall of being with geared assembly 122.Described equipment also comprises: the thread core 3C of annular, and it is fixed on (not shown) on the plate 3; The core 4C of annular, it is fixed on (not shown) on the plate 4; The core of annular or stripper cover 5C, it is fixed on (not shown) on the plate 5.

The core 6 that the core 6C of annular is fixed in (not shown) annular on the plate 6 portion within it has cavity (void) 8 of annular and the pipe 7 of hollow, its be used for cooling water expansion tank conduct to annular core 6 uppermost region or at least on the upper wall 102 of closure member 100.Core 6 parts of the annular on closure member 100 upper walls 11 form inwall, and its feature comprises the inwall that is shaped according to outer wall, and feature forms filling core device 208, the inner wall surface of lift slope 209 for example,, its can be parallel to form in corresponding lift slope geared assembly 310 that filling cover 300 inboards be meshed on or outside face.

The die apparatus operation is as follows.

Cooperation between core 1C, 2C, 3C, 4C, 5C and the 6C of last internal mold (cavity insert) 9C by mould part and annular, the plastics of fusing 502 inject through the aperture under pressure, and described aperture 502 is communicated with the cavity V2 phase fluid at mold closed position place shown in being formed at.Therefore, cavity forms according to desired shape, to make filling closure member 100.

Plastics are injected into after the cavity V2, solidify by the transfer of heat plastics, described transfer of heat passes through last internal mold 9C to cooling-water cycle passage 9W, and pass through annular core 6C to cooling-water cycle passage 8W, it can divide and further stretch to the positioning function part 202 of annular by using than the reduced diameter portion of the hollow tube 7 of minor diameter and water circulation channel 8W, and can realize that if necessary described extra cooling mechanism can be the one or more forms of passing through the cooling-water cycle passage of annular outside core 2C (not shown) by adding extra cooling mechanism.

By the relative motion between plate 6 and plate 1,2,3,4,5 and 9, make plate 6 move along direction " C ", fully to remove the core 6 of annular, come to generate cavity in the inside of the filling core device 208 of the positioning function part 202 of adjacent rings at least, thereby provide cavity, when mould was opened, the positioning function part 202 of described annular can be partial to described cavity.

Then, when plate 9 was mobile along direction " O ", mould was opened at parting line 9A place.

Then, plate 1,3,5 with 6 along consistent the moving of direction " O ", and plate 2 and 4 does not move or does not move with respect to plate 1,3,5 and 6 at least, and the relative motion between the core of the annular that is connected with plate produced void space, and sealing member 40 and part tamper-evident band 110 and tamper-evident geared assembly 122 can be partial to described cavity.The core 4C of annular closes cavity V1 and opens the similar cavity of contiguous sealing member 40 along the relative motion of direction " C ", and move the outside core 2C of the annular of similarity distance with respect to core 1C, open and contiguous surreptitiously open with 110 and surreptitiously open the similar cavity of being with geared assembly 122.

Then, plate 3 stops to move, and plate 1 and 5 continues to move along direction " O " at least, causes the relative motion between plate 3 and plate 1 and 5, thereby causes thread core 3C to break away from from closure member 100.Now closure member 100 separates with core 2C, 3C, 4C and 6C and by stripper ring 1C clamping, and the lower surface 21 of the core of annular or stripper cover 5C and upper wall disk 20 is kept in touch.

Then, plate 1 stops to move, and plate 5 continuation are mobile along direction " O ", thereby causes core 5 that moulded closure is released from stripper ring 1C.

Then, plate 5 stops to move and closure member is ejected from the mould.

Then, mould is closed, to prepare next infusion cycles.

To discuss the further improvement in the mold design now.

Distance " I " is core 3C, the 4C that can be used for holding annular, the total space of 5C, 6C.At least because following reason is desirably in the big multi-cavity mold of at high speed operation cycle time very much, the distance that has " I " is big as much as possible.

The diameter that can expect core 6C is big as far as possible, make hollow tube 7 and aquaporin cavity 8W have enough diameters to hold the stream of a large amount of cooling water expansion tanks, thereby make moulding part more early to solidify and to be pushed out, thereby make mould in specified time, can produce more parts.

Also can expect core 3C, the 4C of annular and the wall thickness of 5C, and can hold greatly to guarantee the firm of mould structure, make its sustainable millions of times circulations apart from the size of " H " and any spacer sleeve (not shown).

Preferably, this distance of distance " F " length of geared assembly 122 (surreptitiously open band) and distance " G " for from the end of surreptitiously opening band to become distance with a position that parallels of the core of annular of the outer wall of the core 3C of annular, and the parallel position distance " G " and " F " of axle with the core of annular that becomes of the outer wall by the core 3C that reduces in annular, making increases thus apart from " I ".

For determining of distance " I ", angle " E " is also very important.Less than 50 ° and be preferably 45 °, or it is far away from described axle to become parallel with the axle of the core of annular the position less than the outer wall of the core 3C of annular by limited angular " E ", thereby increases distance " T ".

With reference to Figure 19 to 23, now another aspect of the present invention will be described.Described figure takes from the patent No. 5,755,347 US Patent, and it illustrates and has the closure member 32 that surreptitiously opens with 35.Described band is molded at expanding location as shown in figure 21, and in order to help closure member is applied on the container thereafter, and mate 40 is by folded position to as shown in figure 19.

With reference to Figure 20, mate 40 has the sections 43 that is separated by slit S, and it is used to reduce the circumferential strength of the free edge of mate 40, thus make its can be more easily by surreptitiously opening band on the container neck.Yet, must keep enough circumferential strength so that mate 40 is remained on engage position, and mate 40 surreptitiously to open the interference that exists between the flange 37 in container be necessary.

With reference to Figure 23, when rotation when removing closure member, surreptitiously open the following side contacts that surreptitiously opens flange 37 with 40 free end and container, and the axial force that is applied is passed to by mate 40 and surreptitiously opens with on 35 the main body.Described power also can be expressed as primary action in roughly passing through on the vector of line F.Yet the described power of part will be by on the geometric configuration of each funtion part 41,42,43 and the direction that relative position guides to " K ", and this will cause being with 35 outwards distortion, and thereby hinge-point 41 is outwards moved.This is used to increase the angle of mate 40, and causes the increase of the application force on the K direction and the minimizing of the application force on the L direction.

At last, mate 40 deformables make that will surreptitiously not open band just can reverse from the closure member separation, thereby obstruct the tamper-evident features of the expection of closure member 40.

Have enough thickness with 35 and resist distortion by making, the problems referred to above can be dissolved to minimum.Yet, described thickening can make described band stretched container surreptitiously open flange more the difficulty, thereby cause closure member to be difficult to more be applied on the container.

Figure 24 takes from the patent No. 6,640,988 US Patent, and here, its content is introduced into this specification sheets by the mode of cross reference.According to Figure 24, a kind of closure member that surreptitiously opens band that has is disclosed, wherein mate 40 comprises the element of many separation, its from the lower end or hinge-point 41 hinged.Described setting is with respect to as the patent No. 5,755, and the prior art of 347 US Patent has lot of advantages, and this is because when using closure member, does not need to overcome the circumferential strength of the mate that surreptitiously opens band.

Yet, also having problem, the force vector that acts on by mate 40 outwards moves hinge-point 41, and causes the counter-rotating of mate 42 before separating frangible bridges 38, thereby has destroyed the realization of tamper-evident.

The patent No. 6,551 can be used in aspect below the present invention, and disclosed mould equipment and method are made in 093 the US Patent, and described US Patent is introduced into this specification sheets by the mode of cross reference.Of the present invention providing in this respect has the closure member that surreptitiously opens band, and the mate 40 that it has more than has the force vector angle of removing of direction of closing L, and makes when removable masterpiece is used for mate 40, reduces and surreptitiously opens the tendency of outwards being out of shape with 35.This can realize by the axle that hinge-point is located adjacent to closure member.Described relocating by surreptitiously opening in the thickening of hinge-point 41 places is with 35 to realize.In the case, force vector angle is reduced, and is used on the L direction and small part acts on the K direction thereby cause major part to remove masterpiece.And thicken and help resist outside distortion described having, it helps to keep the position of hinge-point 41, thereby keeps maximum force vector on the L direction.The thin part of described band above the hinge-point 41 has stayed a zone, and during using, when mate 40 surreptitiously opened flange 37 by container, the free part bendable of mate 40 was gone into described zone.

With reference to comparative drawings figs 25 and 26 (prior art), when removing, act on hinge-point 41 and be reduced about 60% (being reduced to about 5 degree) from about 15 degree with the described force vector that stretches with 35; And make the increase of circumferential strength will further help to resist the stretching of described band when removing by thickening described bottom with 35.All these changes act on guarantees that together therefore hinge-point 41 resists outside moving more removing under the stress, guarantee that mate 40 is clamped in the appropriate location to realize surreptitiously opening the separation of band from closure member.

Describe other one side of the present invention now with reference to Figure 27 to 33, and it also relates to tamper-evident and cell therefor neck, and the closure mould assembly.
