Threaded cap 1100 has threaded cap body 1200 and seal mouth ring 1300.Threaded cap body 1200 has top board 1210 and sidewall 1220.Top board 1210 is disc-shapes.Sidewall 1220 is along the periphery of top board 1210, towards extending with the direction (below in the drawing) of the face orthogonal of top board 1210.Sidewall 1220, it is parallel to each other by the face (inner peripheral surface) of container 2000 sides and the face (outer peripheral face) of above-mentioned inner peripheral surface opposition side.In addition, on the inner peripheral surface of sidewall 1220, has the screw part 1230 that can screw togather with the threaded portion 2120 of container 2000.
Connecting portion 1310 is disposing several along the ora terminalis (the last ora terminalis of top among the figure) of seal mouth ring 1300 with predetermined space.Each connecting portion 1310 is connected with sidewall 1220 ends of threaded cap body 1200.Like this, several connecting portions 1310 are connected with seal mouth ring 1300, threaded cap body 1200.In addition, connecting portion 1310 with the Joint strenght of threaded cap 1200, seal mouth ring 1300 is, during with seal mouth ring 1300 relative reversing, this connecting portion 1310 can easily rupture the user with threaded cap body 1200.
Hinged joint 1320 forms tabular.One end of this hinged joint 1320 is connected with the face (inner peripheral surface) by container 2000 sides of seal mouth ring 1300, and the other end is a free end.When seal mouth ring 1300 is configured on the peristome 2100 of container 2000, Access Division 2130 clampings of the other end of hinged joint 1320 and peristome 2100.
Threaded cap 1100 with seal mouth ring 1300 before use, carries out injecting the liquid injection process of aforesaid liquid earlier in vessel 2200.Behind this liquid injection process, under threaded cap body 1200 and state that seal mouth ring 1300 is being connected, threaded cap 1100 is screwed on the container 2000, carries out the airtight operation of screwing togather of leakproof tank 2000.By above-mentioned screwing togather, the hinged joint 1320 of seal mouth ring 1300 from the open mode shown in Fig. 6 (b), becomes and is state shown in Fig. 6 (c), that be folded into seal mouth ring 1300 inboards (vessel side).In addition, by above-mentioned screwing togather, seal mouth ring 1300 moves along the central axial line of peristome 2100, is configured in the below of threaded portion 2120.
After seal mouth ring 1300 was configured in the below of threaded portion 2120 as described above, as described above, the free end of the hinged joint 1320 that is bent was with Access Division 2130 clampings.By this clamping, prevent that seal mouth ring 1300 is from peristome 2100 disengagements.In other words, by above-mentioned clamping, prevent that seal mouth ring 1300 from crossing Access Division 2130, moving along the central axial line of peristome 2100.Therefore, when the user will use bottle interior liquid, the air-tight state (initial Kaifeng) of threaded cap 1100 to be removed earlier, at this moment, being connected of threaded cap body 1200 and seal mouth ring 1300 must be removed.In addition, as mentioned above, threaded cap body 1200 is connected with seal mouth ring 1300, as long as reversed just easily fracture relatively, so, twist threaded cap body 1200 towards the Kaifeng direction, just can remove being connected of threaded cap body 1200 and seal mouth ring 1300.Therefore, make threaded cap body 1200, make connecting portion 1310 fractures, threaded cap body 1200 is taken off spiral shell, just can remove the airtight of container 2000 towards Kaifeng direction rotation.Like this, threaded cap 1100 must make connecting portion 1310 fracture when initial Kaifeng, so, judge at an easy rate by threaded cap 1100 airtight container 2000, whether broken a seal.
Above-mentioned seal mouth ring 1300 has two kinds of patterns, and a kind of have a hinged joint 1320a shown in Fig. 7 (a), and another kind has the hinged joint 1320b shown in Fig. 7 (b).
Hinged joint 1320a shown in Fig. 7 (a), the end of one end and seal mouth ring 1300 (bottom of below among the figure) joins in full week of inner peripheral surface, and the other end is a free end.Hinged joint 1320a forms has the continuous wave pattern shape of some node.Hinged joint 1320a when on the peristome 2100 that is installed in container 2000, shown in Fig. 6 (c), is folded into the inboard of seal mouth ring 1300, its free end and Access Division 2130 clampings as mentioned above.
Hinged joint 1320b shown in Fig. 7 (b) at the bottom inner peripheral surface along seal mouth ring 1300, is provided with several along interior week with preset distance.The end of hinged joint 1320b links to each other with the inner peripheral surface of seal mouth ring 1300, and the other end is a free end.Therefore, hinged joint 1320b is different with hinged joint 1320a among Fig. 7 (a), and each hinged joint is separately independently, and Access Division 2130 clampings of the free end of each hinged joint and container 2000 prevent that like this seal mouth ring 1300 from throwing off from peristome 2100.
Threaded cap 1100 is not only before initial Kaifeng, and container 2000 is airtight.Even behind Kaifeng, when being screwed on the peristome 2100 once more, also can be again that container 2000 is airtight.For this reason, threaded cap 1100 has the sealing 1400 of leakproof tank 2000 conscientiously.Fig. 8 (a) is the amplification profile diagram of expression sealing 1400.
Sealing 1400 be configured in top board 1210 near.Sealing 1400 has inner seal ring 1410, outer seal ring 1420 and end face seal ring 1430.
End face seal ring 1430, outstanding from the inside face of top board 1210, relatively be configured to ring-type with the end face 2140 of peristome 2100.In other words, end face seal ring 1430 is configured to ring-type along the outstanding predetermined length of central axial line L.When threaded cap body 1200 was screwed on the peristome 2100 of container 2000, this end face seal ring 1430 contacted with the end face 2140 of peristome 2100.
In the threaded cap 1100 of above-mentioned prior art, when seal mouth ring 1300 has hinged joint 1320a, because this hinged joint 1320a forms corrugated, so, in the time of on being screwed to container 2000, this hinged joint 1320a is not easy inwards to bend sometimes, perhaps the shape instability of Zhe Ruing.In addition, because hinged joint 1320a is and is connected in the full week of bottom inner peripheral surface of seal mouth ring 1300, so, at the aforesaid liquid injection process and screw togather in the airtight operation, produce the situation that drop accumulates in the gap of seal mouth ring 1300 and the hinged joint 1320a of bending, can not discharge sometimes.
In addition, in the above-mentioned existing threaded cap 1100, when seal mouth ring 1300 has hinged joint 1320b,, accumulate so can prevent above-mentioned drop owing to have at interval between adjacent hinged joint.But, when hinged joint 1320b inwards bends, because each is naturally independently, so adjacent hinged joint 1320b does not wait with respect to the angle of seal mouth ring inner peripheral surface.Therefore, when opening threaded cap 1100, some connecting portions 1310 are not easy side by side to rupture, and it is big that moment of rupture becomes, and can not easily remove being connected of threaded cap body 1200 and seal mouth ring 1300.Addressing this problem is the 1st problem of the present invention.
In addition, when threaded cap 1100 screws togather on container 2000,, advance towards vessel 2200 skiddings at leisure along central axial line L around central axial line L rotation.Above-mentioned existing threaded cap 1100, owing to have sealing 1400, so when screwing togather on container 2000, sealing 1400 contacts with peristome 2100, because friction force is subjected to the impedance counteragent in working direction.In addition, when screw thread lid 1200 was advanced, sealing 1400 was pushed towards the direction of leaving container 2000 by container 2000.Therefore, above-mentioned counteragent is along with the advancing of threaded cap 1100, promptly along the displacement of central axial line L and change.The variation of above-mentioned counteragent is represented in Fig. 8 (b).
Among Fig. 8 (b), curve I represents the counteragent by inner seal ring 1410 generations.Curve O represents the counteragent by outer seal ring 1420 generations.Curve T represents the counteragent by 1430 generations of end face seal ring.The counteragent sum that sealing 1400 produces, promptly always contact counteragent, with dashed lines S represents.In addition, among Fig. 8 (b), above-mentioned total contact counteragent, the counteragent sum of expression inner seal ring 1410, outer seal ring 1420, end face seal ring 1430.
Threaded cap body 1200 is at displacement A place, and the leading section of inner seal ring 1410 contacts with peristome 2100.Because this contact, produce counteragents, contact counteragent in promptly by inner seal ring 1410.Threaded cap body 1200 continues to advance, and at displacement B place, outer seal ring 1420 contacts with peristome 2100.Because this contact is produced counteragent, is the outer contacting counteragent by outer seal ring 1420.
Threaded cap body 1200 continues to advance, and at displacement C place, the protuberance summit of inner seal ring 1410 and the front end of outer seal ring 1420 contact with peristome 2100.Like this, inner seal ring 1410 and outer seal ring 1420 push towards the displacement maximum of leaving container 2000 directions because of container 2000 in screwing togather.Therefore, above-mentioned interior contact counteragent and outer contacting counteragent are maximum.In this specification sheets, the maximum counteragent of above-mentioned inner seal ring 1410 as imperial palace contact counteragent, the maximum counteragent of above-mentioned outer seal ring 1420 as maximum outer contacting counteragent.In addition, at the peristome 2100 of container 2000, inner peripheral surface and outer peripheral face extend substantially abreast.Therefore, in screwing togather, inner seal ring 1410 and outer seal ring 1420, above-mentioned court leaves the displacement of container 2000 directions, can not surpass bigger than above-mentioned maximum displacement.Therefore, when threaded cap body 1200 continued to advance, interior contact counteragent and outer contacting counteragent were stabilized on the certain value that reduces than maxim.
Threaded cap body 1200 continues to advance, and at displacement D place, the front end of end face seal ring 1430 contacts with peristome 2100.Owing to this contact, end face seal ring 1430 produces counteragents, is end face contact counteragent.Threaded cap body 1200 continues to advance, and in the time of on being screwed on peristome 2100 fully, advancing stops.
Above-mentioned counteragent is the resistance that threaded cap body 1200 is advanced, so the moment when screwing togather threaded cap body 1200, to twist solid moment influential.Specifically, above-mentioned total contact counteragent is big more, needs the big more solid moment of twisting when screwing togather threaded cap body 1200.Owing to the advance displacement of above-mentioned counteragent along with threaded cap body 1200 changes, so, and solid moment twisted also along with above-mentioned displacement changes.Twist the situation that solid moment changes along with above-mentioned displacement, shown in Fig. 8 (c).
Usually, when being screwed on external screw thread on the negative thread, along with the screwing togather of external screw thread, be external screw thread, twisting solid moment and increase along the advancing of central axial line.But, above-mentioned existing threaded cap 1100, when screwing togather on container 2000, shown in Fig. 8 (c), before displacement C, above-mentioned value of twisting solid moment sharply rises, and in the position of having crossed displacement C, above-mentioned value of twisting solid moment sharply descends.This is because above-mentioned inner seal ring 1410 and outer seal ring 1420 side by side produce maximum counteragent, side by side reduces the reason of counteragent thereafter again.Therefore, because above-mentioned total contact counteragent steep variation, so as mentioned above, the value of stubborn solid moment is steep variation also.
Sharply increase if twist solid moment, threaded cap 1100 is not easy to tighten, and the user is caused big burden.
Sharply descend if twist solid moment, when being screwed to threaded cap 1100 on the container 2000, threaded cap 1100 may dally.
Like this, above-mentioned threaded cap 1100 can not be with required intensity, stably screw togather.Addressing this problem is the 2nd problem of the present invention.
In order to solve above-mentioned the 1st problem, the 1st purpose of the present invention provides a kind of threaded cap, this threaded cap in filling when screwing togather behind the liquid, can easily screw togather, and, when threaded cap breaks a seal at first, the threaded cap body is separated with seal mouth ring, threaded cap can be turned on, and can prevent that drop from accumulating between above-mentioned seal mouth ring and the hinged joint

As mentioned above, have the threaded cap 100 of sealing 400, when its threaded cap body 200 screws togather on container 2000,, advance towards vessel 2200 skiddings at leisure along central axial line L around central axial line L rotation.Threaded cap 100 is owing to have sealing 400, so, toward container 2000 on, screw togather, when threaded cap body 200 was advanced, sealing 400 contacted with peristome 2100, owing to friction force, was subjected to the counteragent of impedance at direct of travel.In addition, when screw thread lid 200 was advanced, sealing 400 was pushed towards the direction of leaving container 2000 by container 2000.Therefore, above-mentioned counteragent is along with the advancing of threaded cap body 200, promptly along the displacement (along the miles of relative movement of central axial line L) of central axial line L and change.The variation of above-mentioned counteragent is represented in Fig. 3 (b).
Among Fig. 3 (b), curve I represents the counteragent by inner seal ring 410 generations.Curve O represents the counteragent by outer seal ring 420 generations.Curve T represents the counteragent by 430 generations of end face seal ring.The counteragent sum that sealing 400 produces, promptly always contact counteragent, with dashed lines S represents.In addition, among Fig. 3 (b), above-mentioned total contact counteragent, the counteragent sum of expression inner seal ring 410, outer seal ring 420, end face seal ring 430.
Threaded cap body 200 is at displacement A place, and the leading section of inner seal ring 410 contacts with peristome 2100.Because this contact, produce counteragents, contact counteragent in promptly by inner seal ring 410.
Threaded cap body 200 continues to advance, and at displacement B place, with the position of peristome 2100 contiguous inner seal rings 410, moves to above-mentioned position P1.Position P1 is the most close sidewall 220 sides, the i.e. position of the most close peristome 2100 sides.In screwing togather, owing to pushed by container 2000, towards the displacement maximum of leaving container 2000 directions.Therefore, above-mentioned in the contact counteragent, be imperial palace contact counteragent.Like this, at inner seal ring 410, the position of imperial palace contact counteragent, as interior maximum counteragent position.At this moment, interior maximum counteragent position is exactly position P1.In addition, at this moment, outer seal ring 420 contacts with peristome 2100.Because this contact is produced counteragent, is the outer contacting counteragent by outer seal ring 420.
Threaded cap body 200 continues to advance, and inner seal ring 410 no longer continues to be pushed towards the direction of leaving container 2000.Therefore, interior contact counteragent begins to reduce from maxim.But at this moment outer seal ring 420 is advanced along with above-mentioned, is pushed towards the direction of leaving container 2000, and the outer contacting counteragent increases.Therefore, shown in Fig. 3 (b), the counteragent of sealing 400 with, promptly always contact counteragent and keep certain.In other words, above-mentioned total contact counteragent remains and contacts counteragent with imperial palace and be same value substantially.
Threaded cap body 200 continues to advance, and at displacement C place, interior contact counteragent no longer reduces, and becomes certain value.At this moment, the front end of outer seal ring 420 contacts with peristome 2100, in screwing togather, owing to pushed by container 2000, towards the displacement maximum of leaving container 2000 directions.Therefore, the outer contacting counteragent becomes maximum outer contacting counteragent, and then, the increase of outer contacting counteragent finishes constantly at this.Therefore, shown in Fig. 3 (b), the counteragent sum of sealing 400, i.e. total contact counteragent remain certain value.In addition, in outer seal ring 420, the position of maximum outer contacting counteragent, as outer maximum counteragent position.At this moment, outer maximum counteragent position is the leading section of outer seal ring 420.In addition, at this moment, end face seal ring 430 contacts with peristome 2100.Because this contact, item face sealing ring 430 produce counteragents, are that end face contacts counteragent.
Threaded cap body 200 continues to advance, and outer seal ring 420 is no longer pushed towards the direction of leaving container 2000.Therefore, the outer contacting counteragent reduces from maxim.But at this moment the end face seal ring 430, advance along with above-mentioned, pushed towards the direction of leaving container 2000, and end face contact counteragent increases.Therefore, shown in Fig. 3 (b), the counteragent sum of sealing 400, i.e. total contact counteragent.Remain certain.
Threaded cap body 200 continues to advance, and at displacement D place, screws togather and is over, and advancing stops.Therefore, the minimizing of outer contacting counteragent stops, and simultaneously, at this moment the increase of end face contact counteragent also stops.Therefore, shown in Fig. 3 (b), the counteragent sum of sealing 400, i.e. total contact counteragent remain certain.
By above-mentioned structure, in the screwing togather of threaded cap 100, always contact counteragent and be no more than imperial palace contact counteragent.Therefore, shown in Fig. 3 (c), because above-mentioned total contact counteragent steep variation not, so, make moment that threaded cap body 200 screws togather, promptly twist solid moment and can stablize rising.That is, the stubborn solid moment the when threaded cap 100 of present embodiment is screwed on the peristome is steep variation not, and available low moment stably is screwed on the peristome.
In addition, in the present embodiment, in order to reduce the position that stops in interior contact counteragent, produce maximum outer contacting counteragent, the configuration of outer seal ring 420 is maximum counteragent position (leading section) outside the configuration of interior maximum counteragent position (position P1).But, total in order to prevent above-mentioned counteragent steep variation, as long as make outer maximum counteragent position leave preset distance along the direction (central axial line L) that screws togather of threaded cap 100 with position P1, indefinite also on disposing.
In addition, the sealing 400 of present embodiment has end face seal ring 430.But,, then also can omit end face seal ring 430 if the minimizing of the outer contacting counteragent of outer seal ring 420 just can finish to screw togather before the above-mentioned stubborn solid moment of influence.
In addition, in the present embodiment, sealing 400 is integrally formed with screw thread lid 200.But shown in Fig. 4 (b), also can form dividually with screw thread lid 200.At this moment, constitute threaded cap body 200, when constituting sealing 400, on threaded cap 100, also can adopt the sealing 400 of present embodiment with other material with metal.
In addition, the threaded cap 100 of present embodiment is when screwing togather, and inner seal ring 410 is with after container 2000 contacts, for above-mentioned total contact counteragent being remained necessarily outer seal ring 420 contacts, 430 contacts of last term face sealing ring.But, in above-mentioned screwing togather, total contact counteragent become identical with imperial palace contact counteragent cardinal principle after, can keep certain substantially if do not produce steep variation, then also can be after the contact of inner seal ring 410,430 contacts of end face seal ring, last outer seal ring 420 contacts.At this moment threaded cap body 200 is as shown in Fig. 5 (a).In the threaded cap body 100 of Fig. 5 (a), though outer seal ring 420 is to extend towards central axial line L side,, do not extend overlappingly with container.When container 2000 contacted with end face seal ring 430, threaded cap body 200 produced distortion, and by this distortion, outer seal ring 420 contacts with container 2000.
In the above-mentioned structure, threaded cap body 200 is at displacement A, and the leading section of inner seal ring 410 contacts with peristome 2100, contact counteragent in producing.
At displacement B ', container 2000 with interior maximum counteragent position, be that position P1 contacts, interior contact counteragent becomes imperial palace contact counteragent.
Threaded cap body 200 continues to advance, and interior contact counteragent begins to reduce from maxim.
Then, at displacement C ', in order to make above-mentioned total counteragent certain, end face seal ring 430 contacts with container, produces a face contact counteragent.Therefore, can prevent to cause stubborn solid moment steep variation because of above-mentioned total counteragent sharply descends.
Because above-mentioned contact, the sidewall 220 of threaded cap body 200 side's (towards direction of container 2000) distortion inwardly.
Then, at displacement D ', because the distortion of above-mentioned sidewall 220, outer seal ring 420 contacts with container 2000.Because this contact produces and to make the certain outer contacting counteragent of above-mentioned total counteragent, simultaneously, container 2000 airtight more practical.
Threaded cap body 200 continues to advance, and at displacement E ', screws togather end, and above-mentioned advancing stops.Therefore, at this moment the increase that contacts counteragent with end face of outer contacting counteragent also stops.Therefore, shown in Fig. 5 (b), always contact counteragent and do not produce steep variation, remain certain basically.
Threaded cap 100 with above-mentioned sealing 400 produces stubborn solid moment such shown in Fig. 5 (c).Though how many above-mentioned total contact counteragents has some variations, does not produce steep variation, so above-mentioned stubborn solid moment can be stablized rising.That is, the threaded cap 100 of above-mentioned structure, the stubborn solid moment when being screwed on the peristome 2100 is steep variation not, and available low moment stably is screwed on the peristome.As mentioned above, in the sealing 400 of present embodiment, do not produce steep variation, can freely select the configuration of outer seal ring 420 and end face seal ring 430 as long as twist solid moment.
