Large container can be used for store beverage (or other inner matters) once and closure member be removed or use Make drinking vessel.In some cases, closure member can also be designed such that closure member can be used for reclosing and/or again Novel sealing container.Typical large container has mouth of the diameter in the range of 55mm to 65mm, although the term is also applied for having There is the container of mouth of the diameter in the range of 40mm to 90mm.

Typically, bottle is used to store the beverage (or other inner matters) before drinking vessel is poured the beverage into.Such as Usually used bottle for storing beer and other drinks usually has the mouth of a diameter of about 28mm.

Although the closure member described in above-mentioned document is gratifying in many cases, the present invention attempts to provide Improve, which causes closure member and allow the container to be further simplified in some cases, and makes it possible to drop Low material cost and/or manufacture cost, while the performance of closure member is kept, especially open and close, reclose (if needed Will if) and exhaust (if put appearance soda if) easiness and reliability.The present invention is intended to improve closure member Gas barrier property and (such as during pasteurization) closure member particularly under elevated pressure and/or elevated temperature The reliability of sealing between container.The present invention is attempted to the closing described in the application GB1413249.2 in co-pending Part and container provide further improve.

The content of the invention

According to the first aspect of the invention, there is provided container and the metal closure for container, which, which has, limits Go out the opening of axis and the outwardly prominent first component around container, the first component includes multiple circumferentially-spaced The Part I opened, each Part I have with elongated upper face and elongated lower surface element, first The upper face of the element divided and the lower surface are circumferentially approximate horizontal, and metal closure has top component The second component protruded inwardly from skirt component, skirt component including surrounding the inner surface of skirt component, described second Component includes multiple circumferentially-spaced Part II opened, each Part II have with elongated upper face and it is elongated under The element on portion surface, the upper face of the element of Part II and the lower surface be circumferentially it is approximate horizontal, The length that the element of two parts has enables interval and energy of the element through Part I of Part II The lower section of Part I is enough positioned in so as to which metal closure is fixed to container.

Closure member is formed by metal to provide improved gas barrier property compared with plastics closure and improve envelope The intensity and heat resistance of closing member.Metal closure can also be manufactured in a variety of ways, and especially can be by a kind of or more Pressing operation is planted to shape and set shape.It therefore, there is no need to form relative complex 3D shape (with modeling by injection-molded Expect that closure member is the same), it is feasible to form closure member by single flat sheet metal.Additionally provided using metal by two seamings The selection of closure member (its advantage will be discussed further below) is made in component together.In some cases, metal makes With wall thickness, and the therefore amount of material of the reduction for forming closure member can also be reduced, so as to reduce the weight of closure member And/or material cost.

The suitable design (and simplification of closure member) of the feature of closure member makes the shape and function base of plastics closure Originally can reappear.When compared with plastics closure (such as plastics closure described in GB1413249.2), this is being closed The manufacture view of part, particularly provide significant simplified (and thus reducing cost) in terms of large-scale production.

As mentioned, metal closure also has excellent gas barrier property, because even at elevated temperatures, Closure member is also substantially impermeable for oxygen and carbon dioxide.Metal closure can also be recycled easily.Gold Belonging to closure member when being subject to elevated temperature (such as in pasteurizing process) will not be softened, therefore golden in this case Belong to closure member to be less likely mobile or deform.This movement or deformation of plastics closure may be made it more difficult to ensure raising At a temperature of keep gratifying sealing between closure member and container.To closure member and its sealing in pasteurizing process Part will bear elevated temperature and the requirement of elevated pressure is challenging requirement, especially because container is maintained at Pasteurizing temperature is common (for example, when delay appears in filling and closing production line) more than the required time.

Container shown in Fig. 1 also has in its outer surface grasps groove 15, with when container such as (example during manufacture Such as during blow molding) and helped when such as cleaning, fill, passing through robot apparatus in the subsequent process of closing Grasped in closure member.In other embodiment (not shown), it may not be necessary to grasp groove.

Container is typically formed by plastic material such as polyethylene terephthalate (PET) and typically with two rank The molding process of section is formed：Preformed member is formed in the first injection-molded stage, which forms groove The characteristic of 15 tops, then carries out the second blow moulding phases, in the second blow moulding phases, preformed member is blown To form the container shapes of the lower section of groove 15.The antelabium 11 and/or groove of interruption can be used for protecting during blow moulding phases Hold preformed member.Pet container is typically provided with for example in the shallow layer form of silica or carbon or in laminar structure form Barrier material, with improve the resistance to gas permeability of the pet container (particularly oxygen entrance or carbon dioxide discharge).

In certain embodiments, it may also be desirable to, set the kick for being referred to as transfer loop (usually outside for container Prominent 1mm or smaller) so that container is during manufacture and/or can be mechanical on filling production line and closing production line Device is lifted so that container is moved to another position from a position.The transfer loop can for example include around the outside of container The small shoulder (being further described on Figure 11) set.

Container can also be formed by other materials (for example, combination of glass or metal or these materials).Shown in Fig. 4 The example of canister.

Fig. 2A and Fig. 2 B and Fig. 3 A show the metal closure used in the first embodiment of the present invention.Closure member The skirt component 21 to hang down including top component 20 and from top component.In this embodiment, top component 20 has from top The hole portion part 22 of the downside extension of portion's component, and the hole portion part extends into container 10 when in use.Hole portion part 22 carries example Such as the containment member 23 for O-ring (being similar to the O-ring as shown in Fig. 7-10) so that when closure member is installed on container 10 When (by with shown in Fig. 8 B and Figure 10 B in a manner of similar mode), containment member 23 container 10 interior sealing surface 13 with Sealing is provided between hole portion part 22.O-ring is located in groove or sealing gland 23A (referring to Fig. 3 A), the groove or sealing gland It is arranged on the outer surface of hole portion part 22.Provided in WO2011/151630 mentioned above suitable form O-ring and The further details of sealing gland.It should be noted that the wall of sealing gland should be smooth, it is gratifying to ensure Sealing, and closure member is formed by metal and makes it possible to easily to realize that this gratifying seals-this and plastics closure phase Instead, in plastics closure, it may be difficult to avoid the mould closed line in groove (this makes it difficult to provide smooth surface).With There would generally be the cross-sectional diameter of 2mm to 3mm in the O-ring being used together with wide-mouth closure member.Sealing surfaces 13 have axis To length, which is enough for O-ring relative to some vertical shifts of container (for example, since the pressure in container becomes Change) space is provided, and the sealing surfaces typically have at least 8mm and are up to the axial long of 13mm in some cases Degree.

The skirt component 21 of closure member is provided with inwardly projecting second component 24 around the inner surface of skirt component, The second component includes multiple circumferentially-spaced Part II 24A (being in the example shown four) opened.In Part II Each is with upper face 24B, lower surface 24C, the end angled downwards with first end surface 24D and band There is the end angled up of the second end surface 24E.Circumferentially direction is approximate horizontal to upper face 24B, and It is radially approximate horizontal and general planar in shown embodiment.Circumferentially direction is also big to lower surface 11C Level is caused, but can be radially curved or inclined.End surface 24D and end surface 24E is circumferentially square To separately down with it is angled up, and in the shown embodiment, these surfaces are respectively extended beyond under Part II 24A Portion surface 24C and upper face 24B.Angled end and end surface 24D are further described below with reference to Fig. 5 to Fig. 6 With the function of 24E.In an illustrated embodiment, inwardly projecting component in addition is arranged on skirt part, this is in addition Inwardly projecting component include multiple circumferentially-spaced Part III 25A opened.Each in Part III also has top Surface 25B, circumferentially direction is approximate horizontal and is radially substantially in an illustrated embodiment the upper face It is horizontal and general planar.Upper face 25B is in the level height lower than upper face 24B (when the top of closure member Component 20 is observed when being located at the top), the vertical spacing between upper face 24B and upper face 25B is typically big About 2.5mm-4.0mm.Part III 25A also has angled side 25C and side 25D.

Circumferentially direction is separated from each other and vertically not superimposition each other Part II 24A.

Circumferentially direction is also separated from each other and vertically not superimposition each other Part III 25A, but Part III Vertically can at least to a certain extent with Part II 24A superimposition.

Closure member can be fixed to container 10 by the interaction between Part I 11A and Part II 24A. Fig. 5 to Fig. 6 (being discussed further below) is provided when securing the closure on container between Part I and Part II Interaction and O-ring packing position schematic diagram.

In shown arrangement, closure member can be at first position (Fig. 5 A), be revolved in closure member relative to container 10 Turn and move down the second place (Fig. 5 B and Fig. 8 A) reached afterwards and further revolved relative to container 10 in closure member Turn and move further downward to move between the third place (Fig. 5 F and Fig. 8 B) reached afterwards, at first position, second Divide the upper face 11B of 24A (or at least a portion of Part II) engagement Part I 11A, in the second place, sealing Component 23 contacts container 10 and the grid alignment between Part II 24A and Part I 11A in unsealed position, the 3rd At position, containment member 23 has been moved downward the sealing surfaces 13 to sealingly engage container and Part II 24A is located at The lower section of Part I 11A and contacted with the substantially whole circumferential lengths of the lower surface 11C of Part I.

Make contact between the upper face 24B of Part II and the lower surface 11C of Part I in the third place most Bigization is important.First, it is desirable to minimize the length of Part I 11B, so that influence of the Part I to the appearance of container Minimize, and minimize Part I and the contact of the lip of the user drunk from container, but secondly, it is desirable to make full use of Contact between Part I 11A and Part II 24A, to secure the closure on container, and is especially resistant to seal Being upwarded pressure caused by the elevated pressure in container in closing member (if for example, container include soda and/or When being subject to elevated pressure).

The embodiment shown in figure is designed to be used together with soda (in addition to Figure 26).For given The container (therefore the area for being subject to internal pressure of closure member is given) of diameter, it may be determined that the upper face of Part II Desired minimal-contact area between 24B and the lower surface 11C of Part I.For example, for being about with its interior diameter 60mm (overall diameter is about 62mm) it is mouth, accommodate soda and be subject to the up to large container of 40 degree celsius temperatures and Speech, it is desirable to which the superimposition area is at least about 100mm².For the embodiment with four Part I (and four Part II) For, if for example, Part I each has the length of 25mm therefore the combination circumferential lengths of Part I 11B are about If 100mm (at this time about the 50% of this outer perimeter for representing container) and the radially projecting about 1.0mm of Part I, this is can be real Existing.Preferably, avoid that Part I 11B is significantly radially projecting, so that their contact is minimized and therefore made pair The influence of the lip of the user drunk from container minimizes.In the embodiment shown, can also be by the way that Part I 11B be determined Position reduces Part I pair at the position that the upper end with container is spaced apart, below the top for example in container at 10mm The influence of the lip of user.

For the embodiment with smaller interior diameter (such as about 50mm), the upward pressure on closure member is smaller, Therefore can be for example by using four shorter Part I or by reducing the quantity of Part I (for example, being reduced to three It is a) reduce the combination circumferential lengths of Part I 11B.

The required combination circumferential lengths of Part I proportional (if the footpath of Part I to the area approximation of closure member Keep identical to prominent length, such as 1mm).For the area of closure member reduces 35%, the combination of Part I is circumferentially long Therefore degree can reduce about 35%, that is, it is about 65mm to be reduced to superimposition area².In the example given, this can be by having There are four Part I of about 16mm length or three Part I with about 22mm length to provide.

Embodiment with six groups of Part I and Part II is also described on Figure 24 and Figure 25 below.Although Greater number of part reduces possible superimposition amount, but the horizontal cell of the horizontal cell of Part I and Part II it Between the combination circumferential lengths of superimposition be still maximized.For the embodiment with six groups of Part I and Part II Speech, superimposition is preferably at least the 40% of the girth of container.

Closure member is installed on container and is related to following several stages：Part II 24A is originally located in Part I 11A's Top, then moves Part II, interval of such Part II through Part I and eventually arrives at and makes second Divide positioned at the position of the lower section of Part I 11A.Whole lengths of the upper face 24B of Part II 24A in the upper face Upper (or at least between the inclined end portion 24D and 24E of Part II 24A) is approximate horizontal and general planar, so The upper face of Part II can the lower surface 11C of Part I 11A lower horizontal slide, lower surface 11C (or at least between the end 11D and 11E of Part I 11A) is also approximate horizontal and substantially flat over the whole length Smooth.

In order to which closure member is discharged from fixed position, closure member is rotated relative to container, so that Part II is from the The downside of a part departs from, and moves then up.In the letter without the other device for retaining the closure on exhaust position , then can be by closure member from container lift-off in single arrangement.In other arrangements, it would be desirable to further rotate so as to by closure member Discharged from exhaust position.

Referring back to Fig. 1, it will be noted that, Part I 11A has inclined end surface 11D and 11E.These are tilted End surface with the horizontal about 45 degree, although can use smaller angle.As shown in Figure 1, end surface 11D Lower surface 11C can be extended to from upper face 11B.However, as shown in fig. 1b, end surface 11E can not be under Portion surface 11C extends to upper face 11B.

The end surface 11D and 11E of Part I can also have other forms (for example, as shown in Figure 4).

Moreover, as described on Fig. 2 B, Part II 24A has inclined end, which has end Surface 24D and 24E, the end surface extend beyond lower surface 24C and upper face 24B, for example, as shown in Figures 2 and 3 's.These be further described below.

Fig. 2 to Fig. 7 also shows Part III 25A.As mentioned above, Part III 25A be arranged on be intended to Put in the closure member that is used together of container for holding soda, and the function of Part III be will envelope when in exhaust position Closing member is maintained on container (as described further below).

Fig. 5 to Fig. 6 is illustrated in greater detail is fixed to container (such as by closure member (all closure members as shown in Figure 2) Container shown in Fig. 1) used in step order；The closure member and the container are designed to make together with soda With.

In fig. 5 and fig., the side view of container and closure member is schematically shown with dotted line, and Part I 11A, Part II 24A and Part III 25A are shown in solid, to protrude the interaction between them.

Fig. 5 A show the closure member in the first preloading phase, and in first preloading phase, Part III 25A is put Put on the upper face 11B of Part I 11A (Fig. 5 A show the vertically superimposition of Part III and Part I, because Lower surface for the upper face 11B and Part III 25A of Part I is radially angled or curved). In this position, O-ring 23 is spaced apart with container 10.

Relative to container 10 (it is in the shown embodiment up time along tightening direction in position of the closure member shown in Fig. 5 A Pin direction) after axis A rotations, Part III 25A drops in the interval between Part I 11A, until second Divide the ends rest angled downwards of 24A on the upper face 11B of Part I 11A, as shown in Figure 5 B.This Two preload positions, as shown, O-ring 23 still separate (although only separating a small distance) with container 10.The position (or position shown in Fig. 5 A) corresponds to first position mentioned above.

When position of the closure member shown in Fig. 5 B is further rotated along closing direction, Part II 24A is along first The upper face 11B of part 11A is slided, until the end angled downwards of Part II falls from the end of upper face 11B Under the lower surface 24C of (drops off) and Part II 24A be shelved on the upper face 11B of Part I 11A (such as Shown in Fig. 5 C).It is noted again that in the side view of Fig. 5 C, Part I and Part II seem one Vertically superimposition in degree is determined, because the upper face of Part I and the lower surface of Part II are radially curved It is bent or angled.Nevertheless, Part II is shelved on the upper face of Part I and by the upper face of Part I Support.

In the position, closure member is slightly lower than the closure member of the position shown in Fig. 5 B.Moreover, can from Fig. 5 C Go out, the length (circumferentially direction) of Part II 24A or at least length of the horizontal component of Part II preferably substantially class It is similar to the length of Part I 11A.

As will also be seen that in figure 5 c, in the position, the downside of Part III 25A engagement Part I 11A.

When the position shown in closure member from Fig. 5 C is further rotated along tightening direction, Part II 24A is along first The upper face divided slides, and Part III 25A is slided along the downside of Part I 11A.This move horizontally continue into OK, until Part II end angled downwards end surface 24D (as described above, end surface 24D preferably prolongs Extend over lower surface 24C) reach the end surface 11E of Part I 11A.Then, as shown in fig. 5d, Part II Align in gap between 24A and Part I 11A.It should be noted that the relative vertical position of closure member and container is in Fig. 5 C With it is roughly the same in Fig. 5 D, and as shown, Part III 25A is still located on the lower section of Part I 11A.

Fig. 8 A are viewgraph of cross-section when closure member and container are in the position shown in Fig. 5 D.As will be seen, at this At position, O-ring is contacted with the introducing surface 12 of container 10, and Part I 11A is clipped in Part II 24A and Part III Between 25A.The position correspondence of closure member shown in Fig. 5 D and Fig. 8 A is in the second place mentioned above.As will below by into The description of one step, when closure member is removed from container, which also corresponds to exhaust position.

Therefore, two rotational positions shown in Fig. 5 C and Figure 15 D, closure member relative to container vertical position by Part II 24A on closure member, the Part I 11A that is shelved on container and/or the introducing surface 12 for being shelved on container 10 On O-ring 23 determine.

It will additionally note that from Fig. 5 D, the length (circumferentially direction) of Part II or at least horizontal component of Part II Length is approximately similar to the length at the interval between (and being slightly less than) Part I 11A.This is for such as will be described below The interval that Part II 24A is moved downwardly through between Part I 11A be necessary (even if as will be described , Part II is moved over the ground to oblique).

When position of the closure member shown in Fig. 5 D is further rotated along tightening direction, Part II is at an angle of downwards End inclined end surface 24D from the inclined end surface 11E slide downwards of Part I so that with closure member Rotated, closure member is driven downwards relative to container.Preferably, end surface 24D and end surface 11E are with roughly the same Angle tilt, such as be about 45 degree in an illustrated embodiment, such Part II 24A relative to axis A with the angle to Lower movement.Therefore the rotation of closure member drives downwards Part II, until Part II 24A inclined end surface 24D from The lower end of the inclined end surface 11E of Part I 11A departs from.Then, as shown in fig. 5e, Part II 24A Upper face 24B and Part I 11A downside 11C it is contour.When being further rotated from the position, Part II 24A Slided along the downside of Part I 11A is horizontal, until the end angled up with end surface 24E, (it extends More than upper face 24A) engage the end surface 11E of Part I and stop further rotation, as shown in Fig. 5 F.Will Meeting is it is seen that at this position, and Part II 24A is located at the lower section of Part I 11A, and Part II 24A's is big Cause substantially whole length (the circumferentially side of the approximate horizontal downside 11C of horizontal upper face 24B and Part I 11A To) contact.Therefore Part II 24A is securely positioned at the lower section of Part I 11A, and between Part II and Part I Contact area (it is resisted the closure member caused by the elevated pressure in container and moves up) be maximized.

Fig. 8 B are shown in the closure member of position shown in Fig. 5 F and the cross section of container.As will be seen, O-ring It is driven downwards from introducing surface 12 (position shown in Fig. 8 A), it is substantially round to be engaged around the inner sealing of container The sealing surfaces 13 of tubular.This is related to the compression of O-ring, and (in this arrangement, closure member causes the compression to above-mentioned arrangement The rotation for moving downwards through closure member realize) especially for wherein closure member have relatively large diameter (such as with bottle Son lid compares) wide-mouth closure member for provide compression O-ring needed for power in terms of provide significant mechanical advantage.

Position correspondence shown in Fig. 5 F and Fig. 8 B is in the third place described above.

From the description above it should be appreciated that the position when closure member shown in Fig. 5 D is rotated to shown in Fig. 5 E During position, closure member is driven downwards.The rotation turns over relatively small angle and (depends on the length of inclined end surface 11D Degree and angle), and typically can be in the range of 5 degree to 15 degree.

And it should be appreciated that angle and length of the vertical distance that is driven downwards of the closure member by end surface 24D Degree determines, and end surface 24D extend beyond lower surface 24C enable closure member be driven downwards one it is enough away from From such O-ring 23 is driven downwards from introducing surface 12 and is sealingly engaged with sealing surfaces 13.

It should also be understood that once closure member has been driven downwards the position shown in Fig. 5 E in from the description above Put, then reach further rotating for the position shown in Fig. 5 F and be not related to further push of closure member and be not also related to O-ring 23 further compression, but make Part II firm by maximizing the superimposition area between Part I and Part II Admittedly be bonded on the lower section of Part I.In an illustrated embodiment, closure member revolves between the position shown in Fig. 5 E and Fig. 5 F Turn over the angle in the range of 40 degree of -50 degree.This also means that once in the position shown in Fig. 5 F, then closure member is firm Ground is maintained on container, and before can closure member be removed from container, closure member needs to be rotated back the angle (40 degree of -50 degree) (as will be described further below).Since this rotation is approximate horizontal (rather than in spiral shape spiral shell Inclined like that in the case of line), thus need not be arranged on need to be overcome before this rotation may occur it is any only Dynamic device or other characteristics (for example, being related to the vertical shift of closure member).However, in other embodiment (hereafter into one Step description) in, Part I and/or Part II can be modified to extra to providing some along the rotation for unclamping direction Resistance.

Fig. 6 A to Fig. 6 F show the more detailed order that the closure member of Fig. 2 is removed to step used from the container of Fig. 1. This is substantially opposite with loading sequence described above.

In order to shown in Fig. 5 F and Fig. 8 B latched position discharge closure member, relative to container 10 along unclamp direction ( For counterclockwise in illustrated embodiment) around axis A rotary seal closing member.First, closure member is rotated to the position shown in Fig. 6 A Put, until the end face 24E of the end angled up of Part II 24A is (as described above, the end face extends beyond second The upper face 24B of part 24A) contact Part I 11A end surface 11D.Then, further rotated when from the position When, as depicted in figure 6b, inclined end face 24E, which climbs, goes up (rides up) inclined end face 11D, until Part III The downside of 25A engagement Part I 11A, as shown in Figure 6 C, to prevent the vertical shift of closure member.This in closure member is upward During movement, O-ring 23 is moved to O-ring positioned at the position introduced on surface 12 from sealing surfaces 13 are sealingly engaged, and such as schemes Shown in 8A.It should be appreciated that position of the position correspondence shown in Fig. 5 D shown in Fig. 6 C.

Position shown in Fig. 6 C and Fig. 8 B is exhaust position.Superfluous pressure in container can be by gas in O-ring Seal 23 and be introduced between surface 12, in particular through exhaust groove 14 (as shown in Figure 1A) effusion being introduced into surface and by Release.However, as shown in figure 6c, closure member by the engagement of Part III 25A and the downside of Part I 11A and by It is firmly held on container.As shown in figure 6c, Part I 11A be sandwiched in Part II 24A and Part III 25A it Between.

When position of the closure member shown in Fig. 6 C is along when unclamping direction and further rotating, Part III 25A is along first The downside of part 11A is slided and Part II 24A is slided along the upper face 24B of Part I 11A, until second The end angled downwards of the lower surface 24C for extending beyond Part II divided reaches the inclined end of Part I 11A Portion surface 11D.Meanwhile Part III 25A reach make Part III from the position that the downside 11C of Part I 11A departs from (such as This is no longer prevented from moving up for closure member).This is the position shown in Fig. 6 D (it corresponds to the position shown in Fig. 5 C).

When position of the closure member shown in Fig. 6 D further rotates, the end angled up of Part II is climbed The inclined end surface 11D of upper Part I 11A, and the inclined side 25B of Part III 25A climbs upper Part I The inclined end face 11E of 11A, such closure member tiltedly move up over the ground, as is shown in figure 6e.If carbon is housed in container Acid beverage, then the pressure produced by the soda in container will promote this of closure member to move up.However, for not Application filled with carbon dioxide and for the pressure in container is less than the application of exterior pressure, when along unclamping direction During rotary seal closing member, the effect of the end angled up of Part II in terms of closure member is driven up is required.And And once soda is opened, then the pressure in container is remarkably decreased, and if user recloses container, when again During secondary opening container, the feature driven up will be helpful to lift closure member.

When position of the closure member shown in Fig. 6 E further rotates, Part III 25A can move upwards through Interval between a part of 11A, and closure member is by freely from container lift-off, as shown in Figure 6 F.

As described above, the inclined end of Part II 24A is respectively used to downwardly and upwardly drive relative to container Closure member, and the inclined end is also used separately as block piece to limit closure member relative to container along clockwise direction and edge Anticlockwise rotation.The angle and length of inclined end sections by depending on application scenario, closure member size and The quantity of the threaded portion set around the circumference of closure member.Under more precipitous angle, closure member is driven into downwards sealing Moment of torsion needed for position will bigger, but the angle general for rotating through closure member required for realizing driving to the sealing station Smaller (and therefore inclined part will be relatively short).Inclined part is preferably with the horizontal 45 degree or the angle of smaller Degree, and more preferably into 15 degree to 20 degree in the range of angle.

For the container for being designed to be used together with noncarbonated beverage products, with the embodiment phase for soda Than the superimposition area in fixed position between Part I and Part II can greatly reduce, because closure member needs Upwarding pressure for can bearing substantially reduces.Nevertheless, it is desirable to maximize folded between Part I and Part II Cover, i.e. by make Part I length and the length of Part II circumferentially direction is substantially mutually the same, such Part I Total circumferential lengths can be minimized (and therefore make Part I to the lip of user influence minimize), while still Possible superimposition amount is made full use of (to ensure the firm attachment of closure member and avoid being pressed caused by Part I as Part II Trace damages).

Referring back to Fig. 3 A and Fig. 3 B, the figures illustrate the viewgraph of cross-section of two embodiments of metal closure.Figure Embodiment shown in 3A has recessed hole characteristic part 22 (when viewed from above).The appearance mask of the hole characteristic part It is useful for keeping the recess 23A of O-ring (not shown).

Metal closure can be formed by pressing operation, in pressing operation, be formed by suppressing opposite shape Hole characteristic part 22.Then, the side wall of hole characteristic part 22 is rolled to form the recess 23A for O-ring.

Embodiment shown in Fig. 3 B is similar, and in addition to the 22' of hole characteristic part, hole characteristic part 22' is then Such as (position shown in Fig. 3 A) is formed by punching press with being reversed, the upper face of such closure member is with more conventional Convex form (when viewed from above).The bottom for being reversely formed in recess produces doubling folding part (double backed Fold) 22A, which provides extra circumferential intensity, and to resist the inside flexing of hole characteristic part 22', (this is to introflexion Song can be detrimental to the sealing between O-ring and container).

In both embodiments, the skirt 21 of metal closure has the groove rolled on skirt outer surface, with The protuberance 24A that Part II is provided is formed on an internal surface.Part III 25A can be formed in the portion of lower lip of closure member In, such as when portion of lower lip is flipped up to provide raised edge (as in conventional metal closure), Huo Zhe Three parts can be formed by the other groove rolled in outer surface with formed on an internal surface protuberance 25A (such as Fig. 3 A and Shown in Fig. 3 B).

The function of Part II 24A and Part III 25A is hereinbefore described.These portions being formed in metal lid Point shape and function may be substantially similar to the Part II of plastic closure and the shape of Part III and function (for example, As described in GB1413249.2).The inner surface of the skirt of metal closure can be formed with by plastics (or Other moldable materials) the substantially similar shape of shape of the inner surface of closure member that is formed, although the skirt of metal closure The radius at edge between the adjacent surface of the inner surface in portion and between adjacent part may increase (due to by metal into Shape rather than it is injection-molded manufactured between difference).However, the wall thickness (standard size) of metal closure may be significantly smaller, example Such as in the range of 0.18mm-0.22mm (in contrast, plastics closure is about 1.65mm).

Used metal can be similar to the metal used in conventional metal closure part, for example, as being used for other types The metal for turning on type lid, such as tinplate (low carbon mild steel that the electrodeposit of tin is coated with two surfaces).This Kind material usually has the standard size of about 0.14mm-0.18mm and the yield stress of about 580MPa-620MPa.

Metal closure can be used for the container (as described above) that is molded of plastic material of closing or by other materials The container of formation, such as canister or glass container.

Fig. 4 show it is being formed by metal (rather than plastic material), can with such as on Fig. 2 to Fig. 3 (and Fig. 7 and Fig. 9) the viewgraph of cross-section for the container that described metal closure is used together.The canister is designed to correspond to Figure 1B Shown plastic containers.The metal from internal punching press for example by being formed so that the outer surface of container has prominent the A part of 11A, the Part I have the function of and the shape of the Part I of plastic containers and same shape and function (note that the cross section of Fig. 4 shows these features when being watched from the inside of container).

The outer surface of the part of canister can be formed to have and by plastics (or other moldable materials) shape Into container appropriate section outer surface the similar shape of shape.However, the wall thickness (standard size) of canister is obvious Smaller, such as (in contrast, the neck portion of plastic containers is about 2.0mm- in the range of 0.14mm-0.18mm 2.5mm, and the part of the plastic containers formed by blow molding is about 0.7mm-1.0mm).

The top part of canister is shaped to provide the inclination introducing surface 12 for being used to receive O-ring (with also may be used As being arranged in plastic containers) and exhaust passage 14 in the introducing surface.The upper part of container can have The edge and the introducing surface suppressed or stamped out on the inner surface of upper part and exhaust passage rolled as depicted. The inner surface of the part of canister can be formed to have the appearance with being formed by plastics (or other moldable materials) The similar shape of the shape of the inner surface of the corresponding part of device.However, the wall thickness (standard size) of canister still may be significantly smaller (as described above).

Canister can be formed by the similar metal of the metal with being used in the container for drink of conventional steel.This material Material typically has the standard size of about 0.20mm-0.25mm and the yield stress of about 350MPa-420MPa.

Therefore, the weight and material cost of metal closure or container are smaller than the correspondence closure member being molded of plastic material Or the weight and material cost of container.

Fig. 7 and Fig. 8, which is shown, to be installed on and plastic containers as container class described above or the gold on canister Belong to the further embodiment of closure member.Fig. 7 shows the closure member before being installed on container, and Fig. 8 A, which are shown, to be in Corresponding to the closure member of the position (and the position correspondence is in exhaust position) on the described positions of Fig. 6 C, in the position Place, the introducing surface of O-ring originally engagement angled, and Fig. 8 B show that closure member when on container (and shows Go out how the O-ring that closure member carries deforms at the position).

Metal closure can also be formed with pressing operation, in pressing operation, by suppressing opposite shape come shape Pore-forming characteristic 22.Then, the side wall of hole characteristic part 22 is rolled to form the recess or recess that are used for receiving O-ring 23 23B。

The skirt 21 of metal closure has the groove rolled in the outer surface of skirt, is carried with being formed on an internal surface For the protuberance 24A of Part II.Moreover, groove is rolled in the outer surface of skirt 21, carried with being formed on an internal surface For the protuberance 25A of Part III.Alternatively, can pass through (for example, see Figure 11, Figure 19 and Figure 21) in another kind is arranged The lower terminal edges inward curl of closure member is set to form Part III 25A in the lower terminal edges, for example, working as lower part When terminal edge inwardly overturns edge (as in the conventional metal closure part) to provide protrusion.

Part II 24A and Part III 25A have the function of with above and described in the first embodiment shape and Same shape and function.The inner surface of the skirt of metal closure therefore can be formed to have with by plastics (or Other moldable materials) the similar shape of shape of the inner surface of closure member that is formed.However, wall thickness (the mark of metal closure Object staff cun) it may be significantly smaller, such as (in contrast, the wall thickness of plastics closure is about in the range of 0.18mm-0.22mm 1.65mm)。

As in the first embodiment, used metal can be similar to what is used in conventional metal closure Metal, for example, as being used for the other kinds of metal for turning on type lid, such as tinplate (is coated with tin on two surfaces The low carbon mild steel of electrodeposit).This material typically standard size and about with about 0.14mm-0.18mm The yield stress of 580MPa-620MPa.

Metal closure shown in Fig. 2 and Fig. 7 has two main regions compared between the metal closure shown in Fig. 3 Not.It is the shape for receiving the recess 23B of O-ring packing first, secondly the hole characteristic part 22 above recess 23B Shape.

In the figure 7 in shown embodiment, recess 23B includes upper portion side wall 23C, lower sides 23D and rear wall 23E, That the upper portion side wall is about plane and be approximately perpendicular to axis A, which tilts down and radially-inwardly tilts, It is that the rear wall is about plane and be roughly parallel to axis A and connect upper portion side wall 23C and lower sides 23D.It should manage Solution, since recess 23B is formed by mill operation, so between posterior face and upper portion side wall and lower sides Connection is curved.

Closure member (for example, as described in GB1413249.2) is formed to by O by injection-molded by plastic material The mode that shape ring is maintained at used on hole portion part is applied with limitation, since it is desired that can discharge closure member from mould.In reality In trampling, which needs to keep O-ring by using relatively short flexible fingers, and such closure member can be hit by a bullet from mould Go out.Forming closure member by metallic plate enables O-ring to be kept by lower sides 23D as described above, and it is essential that The side wall extends radially outwardly farther than all flexible fingers as described above.This enables O-ring more firmly to protect Hold and (so when the O-ring is recalled from container, reducing any tendency that O-ring departs from from hole portion part) on hole portion part.This Outside, lower sides 23D projects radially outwardly more remote, and following possibility is smaller：When during exhaust O-ring due in container Pressure unexpected release (and unexpected release of consequential gas) and when being forced upwardly, the pressure of the lifting in container The radial inner portion of O-ring 23 may be acted on so that O-ring may be stretched and/or make the part of O-ring from recess Removed in 23B.If a part for O-ring 23 is forced upwardly between access aperture component 22 and container 10 because the gas discharges (when position of the closure member shown in Fig. 8 B is moved upwards up to the position shown in Fig. 8 A, the size in the gap increases in gap Add), then it may be more difficult to maintain the controlled exhaust of container, and when closure member is ressembled to container, the shifting of O-ring 23 Going out part may be trapped between the frusto-conically shaped portion 22A of hole portion part and container 10, so prevent container to reclose And/or reseal.If the lower sides 23D of recess extends radially outward beyond the lowermost portion of O-ring 23, in container Pressure (and exhaust when gas release) more act on the radially outer part of O-ring 23, so without draw Stretch O-ring or the trend for removing O-ring from recess 23B.

In preferable arrangement, upper portion side wall 23C extends in a radial direction a distance f (before f is compression from rear wall 23E O-ring cross section diameter at least 1/2), and lower sides 23D extends in a radial direction a distance from rear wall 37C S, distance s are at least the 1/2 of distance f.

Alternately or in addition, distance s is preferably at least 1/3 (transversal at this of the diameter of the circular cross section of O-ring Before facial disfigurement), and the preferably 1/3-2/3 of the diameter of O-ring.

For the embodiment with exterior O-ring, when the lower sides of recess have size f and upper portion side wall tool Situation is opposite when having size s, because in this case, O-ring is squeezed into under due to the pressure lifted in container Portion's side wall contacts and is merely useful for O-ring being maintained in recess in upper portion side wall before closure member is mounted to container.

As shown in Figure 7, the part 22A above recess 23B of hole portion part 22 is tilted relative to axis A, therefore should Part 22A has substantially frusto-conical shape, and the inclined angle of the part corresponds to the introducing surface of container 12 angle of inclination, this is introduced into (although including exhaust passage 14 in some arrangements) that surface 12 is also conical butt.Cause This, when closure member is installed on container, the frusto-conically shaped portion 22A of hole portion part is adjacent with introducing surface 12 and substantially flat Row is in the introducing surface 12.It is configured by the shape of device to hole component 22 in this way with the topmost of the inner surface with container Partial shape matches, and can minimize any interval above O-ring 23 between hole portion part 22 and container 10.This It is desirable, because it helps to reduce liquid (or other materials) to greatest extent and is trapped in the possibility in this region (being trapped in the region to may result in pollution and/or the removal of closure member may be hindered, and for consumers unsightly).

Fig. 9 and Figure 10 shows another embodiment of metal closure.This with 8 in Fig. 7 and figure shown in embodiment class Seemingly, in addition to the shape for the recess 23B that O-ring is located at.In this embodiment, the lower sides 23D' of recess 23B is substantially It is plane and is approximately perpendicular to axis A (rather than as in second embodiment be inclined).Lower sides 23D' The one section of distance to extend radially outwardly with upper portion side wall 23C that can extend radially outwardly from rear wall 23E approximately distance s.Cause This, O-ring 23 is located in recess 23B or sealing gland with rectangular shape (with fillet).Such as WO2011/151630 In it is discussed in detail, this is the preferable shape of the sealing gland for O-ring.The sealing gland of this shape also can be just In the application scenario of pressure and negative pressure, i.e., provided in application scenario of the pressure more than the pressure outside container in container close Envelope, vice versa.

As mentioned above, O-ring containment member 23 can also be arranged in the skirt part 21 of closure member Recess 23A is interior and is arranged to the outer seal surface 10C sealing-ins with container 10.Figure 11 A and Figure 11 B are respectively illustrated in close Seal the cross section of this arrangement of position and exhaust position.Figure 11 A and Figure 11 B show installed in by plastic material (or other Moldable material) formed container on metal closure.Incline relative to vertical direction the top part of the outer surface of container Tiltedly, in order to provide inclined surface 10B, when closure member is initially mounted on container 10, O-ring 23 is shelved on the inclined table On face, afterwards, when closure member is rotated down towards sealing station, closure member is used to compress O-ring in the horizontal direction.Therefore, Inclined surface 10B provides the function identical with the introducing surface 12 described in previous embodiment (except being applied to O-ring Horizontal force is in a radially outer direction rather than outside radial inwardly direction.) in both cases, the cross section of O-ring 23 by Deformed in the compression stress in sealing gland, the sealing of recess 23A or groove and container which is located at by O-ring Surface 10C is limited.Moreover, as described above, O-ring containment member 23 can be moved and/or deformed in the sealing gland, So as to especially when seal both sides exist for example due to pressure differential caused by elevated pressure in container in closure member and There is provided between container liquid-tight and gas-tight seal.Exhaust groove (not shown) can be with recessed with the exhaust set in surface 12 is introduced into Groove similar mode is arranged in inclined surface 10B.

Since the closure member shown in Figure 11 uses outer O-ring packing 23, closure member need not be provided with and charge into To the hole characteristic part in the mouth of container (although if necessary to which the hole characteristic part, such as so that closure member still can be provided Airspace between the inner matter of container minimizes).Figure 11 shows closure member, which, which has, is extended across container Mouth general planar top component 20 (although other recessed or raised shapes can be used).

Figure 12 to Figure 19 shows following examples, in this embodiment, closure member by two parts initially separated, That is, skirt part and enclosure portion is formed so that skirt part can be initially secured to the neck of container, with rear enclosed Part is irreversibly fixed to skirt part, to make closure member completely (typically, for example utilize beverage or one in container After a little other foods or other materials are filled).This is further described in the application GB 1522544.4 of co-pending Kind of closure member (and relevant container and formation and method for filling the container).

On narrow-mouth container such as on bottle known to can be removed closure member, filling technique, which intentionally forms, to be used for Headroom above liquid beverage evicts the bubble (being known as foam (fob)) of air from, and when container neck relative narrowness, Filling process can be accurately controlled farthest to reduce excessively filling or overflow (therefore, such filling production line Usually without the cleaning station cleaned before closure member is assembled to container to container neck).Come for large container Say, to realize that this point is much more difficult, overflow and pollution container neck are may result in because being filled within edge 10mm Screw thread in portion, so may need to clean before closure member is assembled.Alternative solution be by will not cause it is foamy in a manner of It is filled, but if not producing foam, air will not be excluded from headroom, therefore inner matter is vulnerable to oxidation.

For the beverage being stored in tank, different filling techniques is used.Tank is filled with liquid beverage, and by filling Enter carbon dioxide and " brokenly bubble " method (using the jet stream of liquefied gas) controls foam height jointly.Once tank is full, tank End the end for being fixed to can body immediately is for example operated by seaming, while continue to be filled with.Therefore, typical tank filling Production line is not only with filling device (carrying relevant gas-filling device) but also with for the end of tank to be attached to tank immediately Main body is to form the seaming station of the minimum closed vessel of internal oxygen.

The remarkable advantage of the embodiment of Figure 12 to Figure 19 is to be filled and closed production line using this tank to form container, should Container has the closure member for being releasably secured to the container, and especially wide-mouth closure member.Therefore, these embodiments profit With following facts：Have by the container and offer that provide the particular form that can be filled and close in an identical manner The container of releasable wide-mouth closure member, conventional tank filling production line is combined with tin seamer, with after tank is filled The tank is closed immediately.

Therefore, the invention enables with resealable closure (and preferably wide-mouth closure member and/or can be in removal The closure member ressembled afterwards) container can be filled on conventional tank filling production line, and enable the container It is enough to be closed by using seaming device, so as to which enclosure portion is irreversibly fixed on skirt part, so as to complete The formation of resealable closure.

As mentioned, enclosure portion can be engaged by seaming and irreversibly be fixed to skirt part, i.e. with Technology in the end of fixed conventional beverage tank (such as, pop can) is identical.This cause improved form container (that is, have can Discharge closure member and the alternatively large container of the closure member with resealable) it can fill and close with existing tank Production line matches, and need to only carry out the modification of very little or need not change.This avoids new or by extensive modifications The needs of substantial amounts of capital investment are carried out in manufactory, so can need not carry out capital investment to new manufacture device In the case of manufacture such as container for drink improved form container.

Figure 12 preferably have to the closure member shown in Figure 19 with above and in GB1413249.2 in co-pending The similar thread forms of the thread forms of description.Other thread forms can be used (but will not to have described in GB1413249.2 Thread forms additional advantage).

Closure member preferably has in such as the O-ring above and described in WO2011/151630 and GB1413249.2 The air locking of form.In certain embodiments, O-ring can surround the external engagement sealing surfaces of the neck portion of container, And in other embodiments, O-ring can surround the inner surface engagement sealing surfaces of the neck portion of container.

It should be appreciated that when container fills (as discussed above) in conventional tank filling and closing production line When, it is important that good sealing is provided between the skirt part of closure member and container (during padding and In the container for completing closing).When container accommodates soda (or inner matter of other pressurizations), the use of O-ring packing It is particularly advantageous for providing this sealing.

Mention as described above, O-ring is preferably mounted in the groove in the skirt part of closure member or installs In the pole of mouth of container is protruded into.Pole is preferably a part for skirt part, but it is also contemplated that other Arrangement, in other arrangements, pole is a part for enclosure portion.Being used in closure member with holding for other forms can be used The containment member of sealing is provided between device (particularly in the application scenario for the demand that need not meet the elevated pressure in container In).

As described above, if container is designed to accommodate soda (or inner matter of other pressurizations), close Part be also preferably designed to first fix and sealing position, to second fix exhaust position it is (interior at the position Glove can be vented, but closure member remains attached to container) and then move between open position.However, it is possible to use other shapes The exhaust of formula.

As described above, a thread forms (screw thread for the GB1413249.2 that all following articles will briefly describe is passed through Form) skirt is fixed to the neck of container.Then, the assembling in enclosure portion to skirt part will be described.

Figure 13 shows large container 10, and the large container is with the opening 10A for limiting axis A and with around appearance The outwardly prominent first component of device 10, first component include multiple circumferentially-spaced Part I 11A opened (shown Example in be four), each Part I 11A have upper face 11B, lower surface 11C, first end surface 11D and The second end surface 11E.Circumferentially direction is approximate horizontal to upper face 11B, but can be radially curved It is or inclined.Circumferentially direction is also approximate horizontal to lower surface 11C, and is radially in an illustrated embodiment It is approximate horizontal and general planar.

The part spaced apart of first component forms the outstanding antelabium of interruption, which can be located at container 10 At upper end or near the upper end, or as in the illustrated embodiment, the upper end of the antelabium and container 10 Portion is spaced apart the distance for example in the range of 6mm-15mm, and preferably 9mm-12mm.The horizontal cell edge of Part I 11A Circumferential direction is separated from each other, and vertically not superimposition each other.

The embodiment shown in Figure 11 as described above is such, in the embodiment of Figure 13 and Figure 14, the appearance of container The top part 10B in face is tilted relative to axis A, in order to provide surface is introduced so that when the skirt part phase of closure member O-ring/deform O-ring is compressed when being drawn downwards for container.Sealing surfaces 10C is led on inclined surface, the enclosed watch Face (as shown) can also be slightly tilted relative to axis A or can be the outer surface of container 10 side it is almost parallel Cylindrical portion.In certain embodiments, multiple exhaust groove or passage (not shown) can be set around the circumference for introducing surface Put at position spaced apart, in order to the exhaust of container.

Container shown in Figure 13 also has in its outer surface grasps groove 15, in order to when container for example during manufacture With washing, filling, close when subsequent process in pass through robot apparatus when closure member is grasped.At other In embodiment (not shown), it may not be necessary to grasp groove.

In certain embodiments, container can be formed by plastic material such as polyethylene terephthalate (PET), and And typically formed with two benches molding process：Preformed member, the first injection-molded rank are formed in the first injection-molded stage Section forms the characteristic of the top of groove 15, followed by the second blow moulding phases, in second blow moulding phases, in advance into Type part is insufflated to form the container shapes of the lower section of groove 15.During blow moulding phases, Part I 11A and/or groove 15 can be used for keeping preformed member.

Container can also be formed by the material of other such as glass or metal or by the combination of material.It is as mentioned above Arrive, some embodiments of the present invention include the canister with metal closure, although can also be by another material Metal closure is set on the container that (such as plastics or glass) is formed.

Figure 12 shows the skirt part 21 of metal closure.Closure member initially include skirt part 21 and individually Enclosure portion 22C (as shown in Figure 15).Skirt part 21 carries containment member 23, such as O-ring so that works as skirt When part 21 is installed on container 10, containment member 23 the outer seal surface 10C of container 10 and skirt part 21 it Between sealing is provided, as shown in Figure 14.O-ring 23 is located at the groove set in the inner surface of skirt part 21 or sealing In gland 23A.

Be described below be related to skirt part 21 initial installation (by enclosure portion 22C be fixed to skirt part it Before).Once by the way that enclosure portion 22C to be irreversibly fixed to skirt part 21 (as described further below) so as to complete Into closure member and user by closure member after container 10 removes, closure member can be then reinstalled on container 10 With closed vessel again.This is related to characteristic threads part (the Part I 11A and of skirt part described below and container Two part 24A) between interaction same order.

In shown arrangement, the skirt part 21 of closure member can be in first position, the second place (in closure member phase Rotate for container 10 and reach after moving down) and further rotated relative to container 10 in closure member and further Move down and move between the third place (correspond to Fig. 3 shown in position) reached afterwards, at first position, second Divide the upper face 11B of 24A (or at least a portion of Part II) engagement Part I 11A, in the second place, sealing Component 23 contacts container 10 and the grid alignment between Part II 24A and Part I 11A in unsealed position, the 3rd At position, containment member 23 has been moved down to be located at the sealing surfaces 10C and Part II 24A for sealingly engaging container The lower section of Part I 11A is simultaneously contacted with the substantially whole circumference length of the lower surface 11C of Part I.

Therefore installation of the skirt part 21 on container is related to following several stages：Part II 24A is originally located in The top of a part of 11A, then moves Part II so that interval of the Part II through Part I 11A and most Zhongdao reaches the position for the lower section for making Part II be located at Part I 11A.The upper face 24B of Part II 24A is whole at its (or at least between the inclined end 24D and 24E of Part II 24A) is approximate horizontal and general planar in length, The upper face of such Part II can the lower surface 11C of Part I 11A lower horizontal slide, lower surface (or at least between the end 11D and 11E of Part I 11A) is also approximate horizontal and big to 11C over the whole length Cause flat.

In order to discharge skirt part 21 (typically by the way that enclosure portion 22C is fixed to skirt from fixed position After part 21 is so as to complete closure member), skirt part is rotated so that Part II 24A from first relative to container 10 The downside of 11A is divided to depart from and be then moved upward.Without other devices for retaining the closure on exhaust position Simple-arranged in, closure member can be then promoted to leave from container 10.In other arrangements, in order to make closure member from exhaust position Put release, it would be desirable to further rotation.

As described above, it is located at the lower section of Part I 11A in fixed position, Part II 24A, and in order to release Closure member is put, it is necessary to mobile Part II so that the gap between Part II and Part I 11A is alignd, such second Dividing can be to pass through these gap.Correspondingly, if it is desired to prevent from removing closure member and/or desirable to provide tamper resistance features part (tamper evident feature), then this can be by will stop that characteristic (not shown) is inserted into Part I 11A Between one or more gaps in realize, to prevent Part II 24A is moved into from aliging and/or passing through with the gap The gap, until stopping that characteristic is removed.

This stop characteristic can provide in a variety of ways.For example, the stop characteristic can be attached to closing It can separate on part or with closure member.The stop characteristic may be arranged so that, when to stopping that characteristic applies foot During enough moments of torsion, which is broken and/or is moved radially outward, and such stop characteristic no longer stops second Align in the gap that part 24A is moved between Part I 11A.In some cases, stop that characteristic is oriented to make , if closure member starts to rotate along release direction, the stop Part II of Part II 24A mating interference characteristics The further rotation of side of 24A.If stop that length of the characteristic with the gap between Part I 11A is approximate Width, then stop that characteristic moves the engagement Part I 11A that can also be blocked characteristic along the circumferential direction for unclamping direction End opposite side prevent.

Referring back to Fig. 1, it should be noted that Part I 11A has inclined end surface 11D and 11E.These are tilted End surface may be with the horizontal about 45 degree, but the narrower angle in the range of 15 degree to 20 degree can be used. End surface 11D can extend to lower surface 11C from upper face 11B.However, end surface 11E can not be from lower part table Face 11C extends to upper face 11B.The end surface 11D and 11E of Part I can also have other forms.

Figure 14 show closure member skirt part 21 and container 10 in the cross section of fixed position.As will be seen , O-ring 23 has been driven downwards to sealingly engage sealing surfaces 10C around the outside of container.This is related to O-ring 23 Compression and above-mentioned arrangement (in this arrangement, the rotation for moving downwards through closure member for causing the compression reality of closure member It is existing) there is the wide-mouth closure member of relatively large diameter (such as compared with bottle cap) especially for wherein closure member for providing Significant mechanical advantage is provided in terms of power needed for compression O-ring 23.

As described above, closure member is formed by two components initially separated：Skirt part 21 is (such as institute in Figure 12 Show) and enclosure portion 22C (as shown in Figure 15).Two components of closure member are preferably formed by metal and can led to Compacting and/or mill operation or other metal-forming techniques are crossed to be formed.For example, skirt part 21 can have in its appearance The groove rolled on face, to form the protuberance 24A for providing Part II 24A on an internal surface.Part III 25A can also be by The other groove rolled in outer surface is formed, to form protuberance 25A on an internal surface.Alternatively, Part III 25A can To be formed in the portion of lower lip of skirt part, such as when portion of lower lip is flipped up to provide raised edge (such as normal In the metal closure of rule) when.

Typically, the wall thickness (standard size) of this metal closure can be in the range of 0.14mm-0.24mm.Made Metal can be similar to the metal used in conventional metal closure, for example, as turned on type for other kinds of The metal of lid, such as tinplate (low carbon mild steel that the electrodeposit of tin is coated with two surfaces).Metal closure Can also by such as be used in known aluminum beverage container and aluminum closure member in, for example as be used for false proof (ROPP) closure member Aluminum sheet is formed.The use of aluminium also allows for setting tamper evident band on the closure, for example, when closure member is removed with sealing Closing member separates drop band or the fracture and and closing when closure member is removed of (and can fall into and grasp in groove 15) The separation band that part leaves together.

Similar tamper resistance features part can be provided in any embodiment in embodiment described here.

As shown in Figure 14, once skirt part 21 has been releasably secured on container, then enclosure portion 22C It can be fixed on skirt part.As shown in Figure 16, such as by by around the angulation of the periphery of enclosure portion 22C The flange 22D of degree is positioned on the pipe 21A of skirt part 21 enclosure portion 22C navigating to skirt part Upright pipe 21A on, to close the opening 21B in skirt part 21.Then, flange 22D is grasped in seaming It can be compressed in work, to form seaming junction surface with pipe 21A, as shown in the viewgraph of cross-section in Figure 17. Therefore enclosure portion 22C is irreversibly fixed on skirt part 21, to complete the shaping of closure member.When skirt part 21 when being releasably secured to container 10, forms complete closure member, such closure member is releasably secured to appearance On device 10.Figure 18 shows the perspective view of the complete closure member fixed to container as Figure 17.

Enclosure portion 22C can be irreversibly fixed to skirt part using other technologies such as gluing or welding 21, although seaming is preferably as seaming is widely used process in canned industry when component is made of metal.

As mentioned before, allow the skirt part of closure member first for forming the above method of resealable closure Container is first assembled to, for example container is filled with beverage with the opening 21B that will pass through in skirt part 21, then, i.e. After container is filled, enclosure portion 22C is fixed to skirt part 21.This novel side for forming closure member Method makes it possible to that the container and closure member of novel form are filled and sealed in conventional tank filling and closing production line Close, and make it possible to provide the novel method of filling container, i.e. by the skirt portion of closure member before container is filled Divide and be releasably secured to container and complete the manufacture of releasable closure member (to close after container is filled Container) method.

Figure 19 A, Figure 19 B and Figure 19 C are that the cross section of the further embodiment of the closure member formed by two components regards Figure.The embodiment is similar with the embodiment shown in Figure 12-19, except some fine distinctions.Figure 19 A are shown in closure member Enclosure portion 22C be fixed to before skirt part 21 and be fixed to the skirt part that container 10 is in sealing station 21.Figure 12-19 shows the simple form of seaming engagement, and Figure 19 shows more conventional dual seaming junction surface.For shape Into such junction surface, as shown in Figure 19 A, the upper end of the cylindrical portion of skirt component 21 be usually bent outwardly or Outwards expansion, and in the seaming junction surface of completion, which is folded, so as to the upper end quilt of cylindrical portion It is folded into inverted u-shaped as shown in Figure 19 B.The flange of the peripheral region of enclosure portion 22C is also formed as and skirt part 21 Inverted u-shaped interlocked U-shaped shape.As shown in Figure 19 B, the periphery of enclosure portion 22C can also be subject to further 180 degree curved Song, to form further inverted u-shaped on junction surface.The junction surface of this dual seaming is well-known and is usually used in End is fixed to metal can.Figure 23 (being described further below) shows such seaming junction surface (in such case Down between container body 10 and base section 16) enlarged view.The junction surface of such dual seaming can be used for owning Embodiment in, wherein, closure member includes two components seaming together, and the bottom of container body passes through seaming to its envelope Closing part is divided to close

Figure 19 also shows another example for the metal closure for being assembled to plastic containers 10.Also it clearly show that The upper end of the outer surface of container is at an angle of (into about 10 degree to 30 degree) relative to vertical direction, has to provide to correspond to The surface 10B on the introducing surface of the embodiment of interior O-ring packing.The outer seal surface 10C of container 10 can be substantially cylinder (and being therefore general vertical) of shape, can also be (usually more into low-angle relative to vertical direction but as shown in figure 19 Up to 5 degree), the diameter of such sealing surfaces 10C somewhat increases with the mouth away from container.When closure member relative to container 10 to When lower mobile, this helps to increase the compression stress on O-ring 23, and helps to ensure that O-ring 23 is compressed, so as to be formed good Sealing, if there is any of the container 10 caused by manufacturing tolerance and/or the diameter of the skirt part 21 of closure member Change or the change there are the circularity of either component if.

Figure 19 B show the closure member that sealing station is on container 10, wherein O-ring packing 23 engagement container Outer seal surface 10C.When closure member is along when unclamping direction and rotating, closure member is moved up relative to container (as on before Described in embodiment), until upward movement is due to the Part III 25A of the protuberance of closure member and the Part I of container The downside of 11A is engaged and is prevented from.O-ring packing 23 connects at the upper end of container with inclined surface 10B It is exhaust position to close location, and such O-ring 23 is no longer compressed so that gas can pass through O-ring 23 from container Inside effusion.

The shape of container shown in Figure 19 is also configured to provide small shoulder 10D below sealing surfaces 10C.This is carried Transfer characteristic part is supplied, so that closure member can be grasped mechanical device automatically and be lifted.

As mentioned above, some embodiments attempt to provide the existing filling and closing with such as using in canned industry The container and closure member that production line matches, with ensure the cost of manufacture container and closure member keep it is relatively low, and preferably with Existing container is equally matched.This also means that investment in terms of manufacturing equipment, for example for filling and closing this container Investment be contracted by.

The embodiment of Figure 20 to Figure 23 is fixed with releasable closure member by one end of offer and is opened and another end The container body opened and provide the another way for realizing this point.When container body is inverted, (so unlimited end exists Topmost), therefore container body shows unlimited cylindrical in form to filling and closing production line, the unlimited cylindrical shape shape Formula can be with the upper end of conventional can body unlimited cylindrical in form it is identical, therefore can be in conventional filling and closing It is filled and closes on production line, and need to only carries out the modification of very little or need not change.In copending application The more details of the method for this filling container are provided in GB1601501.8.

Therefore, which causes the container of improved form (i.e. with resealable closure and alternatively with can weigh The band mouth container of novel sealing closure member) it can match with the filling of existing tank and closing production line, and need to only carry out very little Modification need not be changed.This avoids it is new or by the manufactory of extensive modifications in carry out the need of substantial amounts of capital investment Will, and the container of improved form therefore can be manufactured in the case where capital investment need not be carried out to new manufacture device, Such as container for drink.

Closure member preferably has described in GB1413249.2 with co-pending and such as above for implementation before The similar thread forms of the described thread forms of example.Other thread forms can be used (but will not to have in GB1413249.2 The additional advantage of the thread forms of description).

Closure member preferably also has as disclosed in WO2011/151630 and GB1413249.2 and as in the previous The air locking in O-ring form described in embodiment.In certain embodiments, O-ring can surround the neck portion of container Point outside engage with sealing surfaces, and in another embodiment, O-ring can around the neck portion of container inner surface and Sealing surfaces engage.

It should be appreciated that when container is filled (as discussed above) in conventional tank filling and closing production line When, it is important that good sealing is provided between the skirt part of closure member and container (during padding and complete Into closed vessel in).When container accommodates soda (or inner matter of other pressurizations), the use pair of O-ring packing It is particularly advantageous for this sealing is provided.The close for being provided between closure member and container of other forms can be used The containment member of envelope (particularly in the application scenario for the demand that need not meet the elevated pressure in container).

Figure 20 shows the embodiment including large container main body 10, resealable closure and container enclosure portion 16 Exploded view, which has at its first end 10A opens around the outside of large container main body in circumferentially-spaced Protuberance 11A forms the first bonded device, which has around the inside of resealable closure in circumferential Second bonded device of protuberance 24A forms spaced apart, the resealable closure are used to pass through the first bonded device and second The engagement of bonded device and be releasably attached on the first end 10A of container body, the container enclosure portion be used for can not The second end 10B of container body 10 is fixed to inversely.

Figure 21 A and Figure 21 B show resealable closure outwardly and inwardly and resealable closure protuberance 24A Perspective view.Further describing for resealable closure is presented below.

Figure 22 A and Figure 22 B show the perspective view and front view of the protuberance 11A of container body 10 and container body. Container body 10 is shown at stand up position, i.e. the first opening 10A of container body utilizes edge should positioned at topmost Bonded device and resealable closure and the installation of the bonded device is described in the container body 10 of orientation.

Container body 10 is formed by metal and with the first end 10A's in container body for limiting axis A First bonded device of the first opening and the first end 10A towards container body.First bonded device includes surrounding container 10 Outwardly prominent first component, first component includes multiple circumferentially-spaced Part I 11A opened (in example shown In be four), each Part I 11A has upper face 11B, lower surface 11C, first end surface 11D and second end Portion surface 11E.Circumferentially direction is approximate horizontal to upper face 11B, but can be radially it is curved or tilt 's.Circumferentially direction is also approximate horizontal to lower surface 11C, and is radially substantially water in an illustrated embodiment It is flat and general planar.Part I has the function of and the shape described in embodiment before and substantially similar shape and work( Energy.

Figure 22 A and Figure 22 B show the engagement of the protuberance 24A and the protuberance 11A of container body 10 by closure member Resealable closure resealable closure being releasably attached to before and after the first end 10A of container body 10 Sectional view.Figure 22 A and Figure 22 B also show the O-ring packing in the groove 23A of the skirt part 21 of closure member 23, which is used to provide sealing between the sealing surfaces 10C in closure member and around the outside of container body 10. Container body 10 and container enclosure portion 16 are preferably formed by metal, although in some cases can be by being, for example, plastics The combination of other materials or material is formed.The preferred form of the present invention is included with the resealable closure also formed by metal Canister, although resealable closure can be formed by other materials such as plastic material.

However, in some applications, it may be desirable to which there is plastic containers main body 10 and the closure formed by metal Divide 16.It may be unsuitable for putting the plastic containers 10 that are formed by injection-molded and then blow molding and hold the carbon for needing pasteurization Acid beverage because the bottom of container may distort during the process, cause the bottom no longer provide container 10 can stand it is steady Fixed platform.During blow molding, wall of a container is subject to biaxial stretching so that the material of container becomes from amorphous forms Firmer crystalline texture.The bottom of plastic containers may be still amorphous, therefore in elevated temperature and elevated pressure It can be deformed under power.In such a case, it may be desirable to cut off the amorphous end of blow molding and side described herein above Formula is by metal enclosed 16 seaming of part to the amorphous end.

Closure member by with described in embodiment before in a manner of substantially similar way be releasably secured to appearance The main part of device.

Once closure member has been releasably secured to container body, then container body can pass through the of container body The second opening in two ends is filled.This can be completed by inverted container, and such second opening is positioned at topmost, then To container body liquid filling body (or other inner matters).As mentioned above, this can be arranged to non-side foamy Completed in the conventional can filling production line of formula filling container.

, then can be by the way that container enclosure portion be opened fixed to the second opening to close second once container is filled Mouthful.Preferably, this is carried out in the closing station of conventional tank filling and closing production line.Container one is filled, container closure Divide for example can be fixed to container by forming seaming junction surface between container enclosure portion and container.This possible class It is similar to top (generally including draw ring) is fixed to mode used by conventional can body.Container enclosure portion 16 and container body 10 the second register, and the flange of the periphery around container enclosure portion is positioned to the standing portion of container body 10 On.Then, flange is compressed to form the seaming junction surface with container in seaming operation.Container enclosure portion 16 is not therefore by Container body 10 is reversibly fixed to complete the shaping of container.Container 10 can then return to stand up position, and seaming engages Portion forms the bottom of container, and by the bottom, container can stably stand on a flat surface.

Figure 23 is that the amplification at the dual seaming junction surface that can be formed between container body 10 and enclosure portion 16 is transversal Face view.As mentioned above, this junction surface form is well-known, and is usually used in (generally including the top of tank The threaded closure of draw ring or narrow diameter) it is fixed to the upper end of can body.

Figure 24 A-24F show the further embodiment of the present invention, the further embodiment and the reality shown in Figure 11 Apply that example is similar, but six groups of Part II of six groups of Part I with the circumference around container and the circumference around closure member. Figure 24 A are mounted in the perspective view of the closure member on container.Figure 24 B and Figure 24 C show container in itself.Except with around appearance Outside six Part I 11A of the periphery of device, which is similar to the container shown in Figure 11, Figure 14 and Figure 19.Figure 24 D are extremely Figure 24 F show closure member, moreover, except six Part II 24A and six the 3rd with the circumference around closure member Divide outside 25A, the closure member is similar with the closure member (for example, closure member of Figure 11 and Figure 21) of embodiment before.

In addition to shorter circumferential lengths, the of Part I 11A and Part II 24A and embodiment before A part and Part II (for example, Fig. 1 with Figure 13 and in Fig. 2 with Figure 12 as shown in) it is similar.But first The combination of the upper face 24B of the lower surface 11A of the approximate horizontal element divided and the approximate horizontal element of Part II Circumferential lengths still maximize, and the bonding length between lower surface 11A and upper face 24B is also maximum in its closed position Change.

The Part III (such as Part III of Fig. 2 and Figure 12) of embodiment before Part III 25A is also similar to that, except There is stop device 25E in an end of Part III, when closure member is rotated along release direction, the stop device is by cloth The end 11D of engagement Part I 11A is set to prevent along unclamping further rotating for direction, until container has been vented, Closure member can be promoted slightly downwards relative to container therewith, so that stop device 25E departs from from end 11A, such the Three parts can continue to slide in the lower section of Part I along release direction.

As shown in Figure 24 C, the lower surface 11C of Part I can be coplanar with the upper face of grasping groove 15. However, situation is not necessarily so and in other embodiments, lower surface 11D can be separated with groove 15.

Figure 25 A-25C show another embodiment similar with the embodiment shown in Figure 24 of the present invention, but are holding Without grasping groove or transfer characteristic part on device.As shown in Figure 25 B and Figure 25 C, inclined surface 10B leads to substantially Columnar surface portion, the surface portion provide sealing surfaces 10A.

There are elevated pressure (if for example, container accommodates soda) primarily with regard in container for above-described embodiment Application scenario describe.However, the pressure that closure member and container can also be used in container is less than the pressure of external container Other application occasion.Such application scenario is filled with warm-served food product including container, and then closure member is mounted to closed vessel, So that the pressure when food cooling in container declines.In such application scenario, it may be desirable to be fixed to closure member and hold Some changes occur for the length and/or angle of the Part I of device and the part of Part II.Figure 26 A, Figure 26 B and Figure 26 C show The schematic diagram of the Part I and Part II (being respectively six in this example) suitable for negative pressure application scenario is gone out.Figure 26 A Show and be located at the Part II below Part I in its closed position, wherein approximate horizontal element is engaged with each other.Figure 26 B Show that closure member is rotated afterwards the exactly part before horizontal cell is disengaged from along opening direction.Figure 26 C are shown Part II is (proper along the Part II unclamped after direction is further rotated and is driven upwardly relative to Part I Just in closure member by before being removed from container).Such as in embodiment before, Part I and Part II are made each other With in addition to driving up closure member and being the negative pressure resisted in container.In this application scenario, of course without requirement of offer Part III or other settings for the pressure from container discharge surplus.

Figure 27 is analogous to the viewgraph of cross-section of the further embodiment of the embodiment of Figure 11, in the further implementation In example, metal closure has plastic components, which is arranged on the inner surface of metal closure.The top of closure member Portion's component 20 and skirt component 21 are formed by metal, and are provided necessary intensity for closure member and (especially be subjected to raising Temperature and during elevated pressure-for example prevent from distorting during pasteurization) and provide required gas barrier property, example Such as to prevent the entrance of oxygen and/or the discharge of carbon dioxide (or other carbonic acid gas).Plastic components, which provides, to be used to receive O shapes The groove of annular seal and Part II and Part III for the thread forms by closure member fixation to the container.It is shown Container with similar using the container shown in embodiment before plastic containers.Plastic components can be by " cladding moulds " (over-moulded) inside of metal parts is arrived so that plastic components is attached to metal parts, and such two components rise single The effect of component.This closure member can also be with the container formed by other materials.

Closure member shown in Figure 27 has the advantages that both metal closure and plastics closure.Metal parts provides strong Degree and gas barrier property, and plastic components provide with more complicated shape, can be for example by injection molding process more The component being readily formed.

In all embodiments, the cross-sectional area of sealing gland is more than the cross-sectional area of O-ring 23, such O-ring 23 can move and/or deform in sealing gland (for example, as shown in Fig. 8 B and Figure 11 A) so that O-ring provides such as Described in WO2011/151630 sealing function (rather than simply become just have circular cross section compression seal Part).As described in WO2011/151630, the O-ring 23 in sealing gland provides very relative to compressive seal Different sealing functions.Position (or the institute from Figure 11 b being moved to shown in Fig. 8 B when position of the closure member shown in Fig. 8 A The position shown is moved to the position shown in Figure 11 A) when, O-ring is moved and deformed in sealing gland.Once it is in Fig. 8 B Position shown in (or Figure 11 A), then if O-ring is subject to increased pressure differential, O-ring can be deformed further with further Strengthen the sealing between container and closure member.When being sealed in when container accommodates soda of being provided by O-ring needs to resist Relatively high pressure differential, (1 atmospheric pressure is about 1 × 10 to for example several atmospheric pressure⁵Pascal) when, O-ring this deformation ( Assemble closure member and during in response to pressure increase) it is especially important.In this case (such as in WO2011/151630 further Description), the compression ratio of O-ring is preferably in the range of 20%-25%, and sealing gland is filled in 50%-90%'s In the range of, and preferably in the range of 65%-85%.

As described above, O-ring packing can be in internal (if Fig. 1 is into Figure 10) or in outside (such as Figure 11-23 In) setting.In latter arrangement, as described above, O-ring packing can be located at the skirt for being formed in closure member In recess in partial inner surface, and be arranged to when closure member is mounted to container and the outer surface of container carry out it is close Envelope.Recess and O-ring can be similar to the recess described in Figure 10 and O-ring with Fig. 1, except being to be arranged on lid Skirt in rather than in hole portion part outside.

Preferably, the top part of the outer surface of container is inclined, so as to provide and embodiment described above The corresponding surface in surface is introduced, to compress O-ring/deform O-ring when closure member is drawn downwards relative to container.

Such closure member can also be provided with the hole portion part being assemblied in the mouth of container as described above.The hole portion part There need not be the recess for being used for receiving other O-ring in hole portion part (although except outer O shapes in the skirt of closure member Interior O-ring as described above can also be set outside ring).With the outer O shapes being arranged in the recess in the skirt of lid Ring (as described above) but the closure member for not having apertured members is also feasible.

Characteristic threads part closure member, being arranged on closure member (and container) with this outer O-ring can be with It is substantially similar, and to work with manner as described above similar mode.

In embodiment described above, Part I, Part II and Part III each surround container and closure member Circumference be angularly equally spaced.However, these parts are possible to be spaced unevenly, for example, if it is desired at one or Big spacing is provided in order to provide more comfortably region is drunk between the part in multiple regions.

Shown embodiment each has four Part I (and four Part II and four Part III), still As described, the pressure that can be designed to bear depending on the diameter and closure member of closure member and container is less to use Quantity or more quantity.In some applications, it may be desirable to provide such as six Part I (and six Part II).So Embodiment can also have six Part III (although can use it is less, such as three Part III).Using most The Part I and Part II of amount can help to provide intensity or rigidity evenly around all bound pair closure members of closure member, This contributes to the tendency for making closure member when being subject to high temperature and high pressure (such as during pasteurization) be twisted into non-circular shape Minimize.As shown in the illustrated embodiment, Part I all have the function of identical form and, and similarly, own Part II have the function of identical form and.

As mentioned, preferably radially direction is substantially to the upper face of the lower surface of Part I and Part II Flat.However, in certain embodiments, such as in bottle neck, these surfaces can be radially angled Or it is curved, as long as the interaction vertically between surface is enough vertically to provide closure member on container Needs fixation.

In the embodiments described, Part I preferably has simple and relative smooth shape, so that first The influence of influence and Part I to the lip of user point to the appearance of container minimizes, and on closure member second (and Alternatively three) the can partly have more complicated shape, because they will not be in contact with the lip of user, and because They are hidden on the inner surface of closure member to a certain extent.However, in the case where these factors are less concerned, first Part can have more complicated shape.A kind of possibility is by the end angled downwards of Part II and angled up End alternatively set over the first portion.Another possibility is to set Part I on the closure and by second Divide and be arranged on container.

For the application scenario of especially filling CO 2, if Part III once below Part II Engagement is released, and helps user to lift closure member by the pressure in container, then end angled up can also be saved Slightly.

As described above, for the Part I and Part II of the thread forms that metal closure is fixed to container With the element with approximate horizontal elongate surface.Between the upper face of Part I and the lower surface of Part II Engagement secures the closure on container and prevents closure member moving up relative to container.Friction between these surfaces connects Close and also prevent closure member from being frictionally engaged along the rotation for unclamping direction until applying enough moments of torsion to overcome.In view of these tables The bonding length in face, in many cases, this is enough the undesigned release for preventing closure member.However, under identical circumstances, For example, if closure member is vibrated, it may be desirable to provides some extra resistances along the rotation for unclamping direction to closure member.It is real A kind of mode of existing this point is (as shown in Figure 24) end of one in surface (such as one or more the On two parts) stop device is set, which engages with a part for first component to forbid rotating along release direction, But this can overcome (then along unclamp direction rotate) by closure member relative to small move down of container.For holding The elevated application of internal pressure of device, stop device can be disposed such that stop device is maintained at when pressure rise At following location：At the position, stop device prevents closure member from rotating, but once the pressure of surplus is discharged, then is closed Part can be depressed to overcome the effect of stop device.

Composition surface is alternatively set to be slightly tilted (such as up to 1-2 degree) so that in order to along unclamping direction rotary seal Closing member, closure member must be slightly moved down, slided because these (are slightly tilted) composition surface on each other.This surface Opposite gradient only need very small, to loosen the resistance needed for providing to the unexpected of closure member, therefore surface is still " approximate horizontal ".

When metal closure is used on plastic containers, it is still desirable to make the contact between Part I and Part II Area maximizes, and otherwise the pressure on plastic components will increase and therefore plastic components may deform.With plastic-enclosed Part is the same, and the circumferential lengths of the approximate horizontal upper face of Part II are preferably the approximate horizontal lower part of Part I At least the 50% of the circumferential lengths on surface or at least 75%.

For the container for holding soda for putting, the circumferential lengths of the approximate horizontal upper face of Part II are preferred Ground is roughly the same with the circumferential lengths of the approximate horizontal lower surface of Part I.

Moreover, each Part I preferably has the week of the circumferential lengths for the element for being approximately similar to Part II To length, and preferably, when closure member is fixed to container, the element of Part II and the institute of the Part I State the substantially whole circumferential lengths contact of lower surface.

For the large container for holding soda for putting, the combination circumferential lengths of Part I be preferably container The substantially half for the outer perimeter being provided with container at the position of Part I.

As mentioned above, at least for the application scenario of filling CO 2, the combination of Part I is circumferentially long Degree is preferably about the 50% of the outer perimeter of container, and under fixed position, Part II and the Part I The substantially whole circumferential lengths contact on portion surface.For the application scenario of non-filling CO 2, and work as lid When being made with container both of which of on-deformable stronger material (such as metal), the combination week of Part I (and Part II) Can be with smaller it is preferred that at least 15%-25% of the outer perimeter for container (or closure member), is sealed with assisting in ensuring that to length Closing member is firmly held on container (draws because closure member may nevertheless suffer from the external pressure due to temperature change or reduction The pressure differential risen).Moreover, if the gap between Part I or Part II becomes too big, there are closure member to turn round The bent risk into non-circular shape, this can damage the sealing between container and closure member.

Similarly, Part II can connect with the length of the whole circumferential lengths of the lower surface less than the Part I Touch.However, the length of contact should be enough that surface can be slided on each other and be enough to bear the pressure that closure member will be subject to Power, but not Part II is become in recessed Part I or otherwise damage Part I.

It should also be understood that the circumferential spacing between Part I must be enough to allow in embodiment from the description above Part II passes through between the Part I.Although Part II may have one or more inclined ends, and this A little Part II can be passed through with an angle between Part I, but the horizontal cell of Part II must be shorter than first / circumferential spacing (no matter the horizontal cell passes vertically through or with an angle by between Part I Gap).

When closure member may be initially applied to by mechanical device during manufacture or in closing and filling production line When on container, the ability that can reclose and reseal container after container is initially switched on of user end should in many With being significant advantage in occasion.For wide-mouth closure member, especially when needing at elevated temperature and/or at elevated pressure When keeping excellent sealing, it can easily apply the setting to closure member come manually removes and again by user end and go back There is provided reliable sealing may be challenging.Thread forms and sealing arrangement described above provide solution party for this Case.
