The utility model has the beneficial effects that:

1), abandoned traditional container seal construction for being directly plugged into formula, then use revolution filling type bottle stopper or Altar lid, and using the external leakproofness of sealing ring, while finally easily ensuring the external sealing effect of container finish, effectively Avoid the occurrence of shot wad phenomenon.Specifically, on the one hand, the presence of swing link, not only by its pass through gap presence without The movement of filling in of capping respective container mouth is influenced, while also because the seam allowance of retention bead and swing link etc cooperates, to limit It covers once filling in and rotating, can effectively prevent covering the phenomenon that being caused bottle stopper to pop up by the variation of air pressure in container hair It is raw.On the other hand, the lower pressure of above-mentioned seam allowance cooperation is then utilized in sealing ring, to can guarantee that sealing ring can be in stress always In the state of compression, this also ensures that the compressing of seal chamber respective container oral cavity wall and sealing effect, finally ensures wine liquid External leakproofness, use are extremely convenient.

It 2) is the sealing effect of lift-off seal circle, as the further preferred scheme of above scheme, the utility model is holding It is additionally arranged necking segment on the basis of the common straight tube moulding of device mouth, on the one hand rely on necking segment using the presence of necking segment Inner ring surface come play limit capping downlink height purpose；On the other hand then come by the upper ring surface of necking segment tight with sealing ring Close fit can be reached with a complete sealing ring surface thus under the action of sealing ring receives the lower pressure of retention bead Its maximum sealing purpose.Especially significantly, since the mill of necking segment inner ring surface and the extended segment bottom end outer wall of capping Sand cooperates, thus while being connected by sealing ring and sealing capping seals together with vessel port and then formation, it is ensured that The formation of two sealings.By the way that the bottom end outer wall frosted of extended segment is handled the barrel chamber for being fitted in vessel port to face tightly At necking segment inner ring surface at wall, to be formed by sealing surface by the two face paste conjunction and realize preliminary sealing function, arrange in pairs or groups Sealing ring Chu bis- is sealed, final to realize the utility model dual-seal ability.Above-mentioned double sealing effect, not only keeps away Exempt from distributing outward for wine liquid, while more avoiding due to wine liquid volatilization directly along above-mentioned extended segment bottom end outer wall and vessel port cylinder The exudation of wall gap and Contact Seal ring, and then there is wine liquid pollution problem, finally ensure the high-quality of wine liquid storage.Specific behaviour On work, the materials such as Duan Weiwei ceramics, glass are preferably extended over, to reduce the materials such as silica gel, the plastics for constituting sealing ring as far as possible Expect the chance contacted with wine liquid in container.

3), the utility model uses capping and the dual lid of inner cover designs, by cover as direct cooperation The sealing cover of vessel port is come sealing ring of arranging in pairs or groups, thus while realizing the primary seals effect of vessel port, then relies on inner cover conduct The fixed of respective container mouth covers, and the function of positioning inner cover is played with locking rod, so that inner cover can not be from radial direction or axis It is detached and comes upwards, the final relieved package purpose realized to any vessel oral area.And it is further, the utility model is also By designing the outer chamfer and inner chamfer that cambered surface is bonded to each other each other, to work as two groups of lids radially pairing, and locking rod is complete When being fully inserted into pin hole to two groups of lids of positioning, at this time because of the ramp structure of inner chamfer, can constantly it be squeezed along above-mentioned radial direction Outer chamfer so that lid make vertical to pressing action.The principle of above-mentioned movement can refer to lozenges structure, when two groups Two pieces of lozenges of sliding block are when face paste is closed each other, once along slope direction misfit top shoe, sliding block relatively upper can be slided Block generates depression, and lid acts similarly.At the mating surface that can be applied to the power of pressing action due to lid and cover, then To capping at the mating surface of vessel port, the corresponding sealing surface also allowed between capping, lid and vessel port is more pasted for conduction It closes.Secondary or even multiple encapsulation after either first sealing or corkage, as long as inner chamfer and outer chamfer cooperation are reliable, then It can all make lid generate lower pressure when closing up lid every time, and then can ensure the sealing effect of lid and vessel port always, Its encapsulation operation can be repeated several times, and be stablized using reliable.

4), when practical operation, for the space orientation for ensuring lock piece, the utility model is provided with the outer of ladder shaft-like Lid.The reduced diameter section of outer cover directly constitutes locking rod, so that the positioning function to inner cover is played, and the shaft shoulder of outer cover then constitutes and stops Mouth acts to limit lock piece along the downlink of pin hole.On the basis of above structure, the utility model is even more to devise Anti-theft card Pin, so that the uplink for further limiting lock piece along pin hole acts.So far, locking rod itself can limit being separated from each other for lid Movement, and the shaft shoulder of outer cover and antitheft bayonet lock also ensure the polarization of locking bar itself, it is all linked with one another each other, finally realize this reality With novel integrative packaging purpose.

Specifically, lid is held at vessel port first when actual assembled, thus by between capping and vessel port Plane fitting or sealing ring sealing etc. modes, carry out optimized integration seal operation.Later, two groups of lids of inner cover will be constituted along diameter To pairing, and ensure that face paste is closed between the inner cavity roof of inner cover and capping top end face.After two groups of lid radial direction pairings, two groups Notch natural involution at the center of lid forms pin hole, at this time by the locking rod of outer cover along vertical to insertion pin hole in, To fill up pin hole.When the shaft shoulder seam allowance of locking rod insertion pin hole and outer cover is matched with inner cover top surface, antitheft bayonet lock meeting at this time It radially pops up and is construed as limiting outer cover rim vertical between the cavity roof of inner cover and cooperate to the seam allowance of uplink.So far, inner cover Radial action is limited by the cooperation of the Tenon of the locking rod of outer cover and pin hole, and the axial action of inner cover is then by gap slot or seam allowance Cooperation between in-flanges or positioning pin and limit, while outer cover again because antitheft bayonet lock there are due to be tightly secured in inner cover On, finally realize the integrative packaging function of outer cover, inner cover, capping and vessel port.Because poroid with kidney-shaped between locking rod and pin hole Or square hole shape section and form anti-rotation cooperation, it is therefore necessary to reverse outer cover by force to twisting off relatively thin locking rod, side It can be only achieved the purpose for destroying outer cover structure, antitheft purpose also can be realized.

5), further, the utility model forms antitheft bayonet lock using the cantilever rod-like structure for tilting upward extension, And the holding tank accommodated for antitheft bayonet lock is set, this makes when outer cover downlink, antitheft bayonet lock can because pin hole there are due to nature It is compacted and is contained in holding tank, to promote its installation effectiveness.And when in cavity of the Anti-theft card pin completely into inner cover, Antitheft bayonet lock can pop up locking rod because of the elastic-restoring force of itself again, be matched at the cavity roof of inner cover to play seam allowance Purpose, so that it is guaranteed that its locating features.

6), in fact, due to antitheft bayonet lock be along inclined direction and it is oblique be upwardly formed, once external force by force to On pull outer cover, then antitheft bayonet lock just very likely along outer cover cavity roof slide, finally there is Anti-theft card because of external force Pin, which is dragged, equals or even drags disconnected phenomenon.In view of this, positioning edge has also been devised in the utility model.The presence of positioning edge, so that even if External force pulls up outer cover by force, so that antitheft bayonet lock can be by positioning edge when antitheft bayonet lock is along the cavity roof sliding of outer cover Seamed edge and block by force, so that limit antitheft bayonet lock extends out movement.The movement that extends out of antitheft bayonet lock is defined, and outer cover is also The anti-theft of the utility model can not be finally improved by by force along axial extraction.

If 7), twist into two parts locking rod in view of forced rotating outer cover, generally require to bestow biggish external force.This is practical new Type is individually arranged annular groove again at locking rod root and is formed by necking segment, so that artificial increases easy stress and deformation Section.When forced rotating outer cover, which can generate deformation because of external force at the first time, and it is existing that fracture finally occurs at this As to promote its degree easy to use.

8), such as without bolt and jack, on the one hand, only lean on the clamping of flanging, it is also possible under the choosing by force of external force, And inner cover is made to be kept closed lower whole abjection lid under the premise of lid cosmetic variation is lesser, it is anti-to thereby reduce it Steal performance；On the other hand, when Rotating outer is to twist off antitheft bayonet lock, it is also necessary to hold first inner cover can Rotating outer apply Power, using obviously more inconvenient.By mutually positioning between bolt and jack, while ensuring property easy to use, it is clear that Further ensure the anti-theft function of the utility model.

For ease of understanding, here in connection with Fig. 1-5, to the specific implementation structure and workflow of the utility model make it is following into The description of one step:

It, in actual use can be by it herein mainly by taking the vessel port a namely bottle sealing of bottle as shown in Figs. 1-2 as an example It radiates in other similar wine jar packaging structure as in Figure 3-5.In order to facilitate observation of, in the premise for not influencing to understand figure Under, delete processing is subject to the hatching of part-structure in figure.

The specific implementation of the utility model and the structure after installation, as shown in Figs. 1-5: bottom is the vessel port a of bottle, The capping 10 of ceramics or similar material is covered at the top end face of vessel port a.Tentatively with sealing ring 20 between 10 and vessel port a of capping Both sealings, then sealed by the way of smooth bevel and frosting to form two, further to prevent the liquid such as wine liquid The volatilization of body.

Specifically, referring to Fig.1 shown in -2, when bottle sealing of the utility model as bottle, bottleneck or even envelope The shape of lid 10 can take the circumstances into consideration to be subject to artistic variation according to existing structure.Regardless of how to convert the shape of bottleneck or even capping 10 The engagement formation of shape, bottleneck and capping 10 must be sealed with sealing ring 20.When practical operation, cover 10 bottom end to Under extend and can protrude into the intracavitary extended segment 10a of bottleneck bottle.Due to extended segment 10a shape in circular cone it is rod-shaped, also just with cover 10 Upper part between form ladder shaft-like structure.In use, 10 from top to bottom grafting bottleneck of capping, extended segment 10a is protruded at this time Bottleneck bottle is intracavitary.Retention bead 11 and sealing ring 20, and the arrangement of retention bead 11 are sequentially provided on the 10a of extended segment in advance Orientation and pattern are subject to can be accurately by the passage gap of swing link b at vessel port a.In use, by by retention bead 11 Passage gap across the swing link b of bottle mouth position is simultaneously sunk under swing link b, then rotary closure 10 is so that limit convex It plays 11 to horizontally rotate to the lower face of swing link b, to form state as shown in Figure 1.At this point, even if because repeating opening and closing envelope Lid 10 and when causing to have certain air in container, due to soft-mediums and bottle mouth position chambers such as the silica gel, the plastics that constitute sealing ring 20 It is formed and is combined closely between wall, hair the phenomenon that so as to effectively prevent capping 10 to be caused bottle stopper to pop up by the variation of air pressure in container It is raw.Furthermore, due to the seam allowance cooperation formed between retention bead 11 and swing link b, so that also allowing for capping 10 can not be direct It is axial to extract bottleneck.Simultaneously as swing link b gives the power that compresses of retention bead 11, the lower anchor ring of sealing ring 20 can be reliable at this time The preset annular protrusion c being pushed against immediately below sealing ring 20 upper ring surface at.

And it is the further leakproofness for promoting capping 10 with above-mentioned bottleneck namely vessel port a, the structure shown in Fig. 1-2 In, the bar diameter of the bottom end of extended segment 10a is actually that the annular protrusion c at identical bottleneck bottle chamber is formed by necking segment shape 's.If necessary, the bottom end outer wall of extended segment 10a and the corresponding portion of bottleneck bottle chamber is further processed by modes such as grindings Point, to further promote the conformability and contact leakproofness of the two by frosting technology, finally ensure to cover 10 and appearance The secondary sealing function of device mouth a.

When the utility model is applied to the sealing of wine jar altar, as shown in Figure 3-4, the utility model additionally uses same each other Outer cover 40 and inner cover 30 that axis is arranged and being from top to bottom set in sequence.At this point, the seal construction of aforementioned bottleneck design structure is used In the frequent opening and closing for realizing wine jar, and the anti-theft of wine jar itself and initial storage sealing effect then rely on following structures real It is existing:

As shown in Figure 3-4, inner cover 30 is downward opening barrel-like structure, and inner cover 30 forms two by subdivision when in use Group lid 30a.When two groups of lid 30a radially double of split as shown in Figure 5, the split side of two groups of lid 30a forms " S " The split gap of shape.To ensure the polarization after lid 30a split, tool as shown in Figure 5 is set at the split side of lid 30a The notch 30c of standby straight flange, after two groups of lid 30a radial split each other, two groups of notch 30c are enclosed each other and are formed kidney slot The pin hole of shape or square hole shape.The upper coarse and lower fine stepped shaft structure of the two-part as shown in Fig. 3-4 is then presented in outer cover 40.Outer cover 40 enlarged diameter section constitutes the external section that exerts a force, in order to grab application torsion.The locking rod 41 of outer cover 40 constitutes draw pin to insert Enter in pin hole, will not be radially separated from each other with playing two groups of lid 30a of constraint.

Further, the utility model is utilized the mechanism of lozenges misfit, and design cambered surface each other be bonded to each other it is outer Chamfering 10b and inner chamfer 30d.Referring to shown in Fig. 3-4, when two groups of lid 30a radially pairing, and locking rod 41 is fully inserted into When pin hole is to two groups of lid 30a of positioning, at this time because of the ramp structure of inner chamfer 30d, in conjunction with the phase each other of two groups of lid 30a Close displacement action can make inner chamfer 30d constantly squeeze outer chamfer 10b along above-mentioned radial direction, so that capping 10 is made Vertical to pressing action.The power of pressing action can be then applied to at the mating surface of vessel port a by capping 10, be equivalent to always Someone bestows capping 10 with downward pressure, and significant increase obviously can be obtained in the cooperation sealing effect of lid 30a and vessel port a. And as user in use, even if destroying above-mentioned theft-prevention structure, because of the presence of inner chamfer 30d and outer chamfer 10b, The progress portion vessel port a be repeated several times and encapsulate using the structure that can rely on the cooperation of its wedge like face after container every time, thus So that the utility model has extremely strong repeatable encapsulation.

As shown in Figure 3-4, the utility model is also axisymmetric on locking rod 41 to be disposed with two groups of antitheft bayonet lock 41a, Namely antitheft bayonet lock 41a is a part of locking rod 41, to be acted using the elastic expansion of antitheft bayonet lock 41a radially, is come It realizes constraint limit function, finally outer cover 40 can be reliably fixed on inner cover 30, and outer cover 40 is avoided to generate upward take off It is acted from inner cover 30.Antitheft bayonet lock 41a can be refined further, as shown in Figure 3-4, at this time since antitheft bayonet lock 41a is Along inclined direction oblique to be upwardly formed, therefore, once external force pulls outer cover 40 upwards by force, antitheft bayonet lock 41a is with regard to pole It is possible that the cavity roof along outer cover 40 slides, finally occurs being dragged because of external force and equal or even drag disconnected phenomenon.In view of this, this reality Positioning edge 32 has also been devised with novel, so that even if external force pulls up outer cover 40 by force, so that antitheft bayonet lock 41a is along outer cover 40 Cavity roof sliding when, antitheft bayonet lock 41a can be blocked by force by the seamed edge of positioning edge 32, to limit antitheft bayonet lock 41a Extend out movement.The movement that extends out of antitheft bayonet lock 41a is defined, and outer cover 40 is also impossible to by by force along axial extraction, Finally improve the anti-theft of the utility model.And if in view of forced rotating outer cover 40 and twist into two parts locking rod 41, often need Bestow biggish external force.The necking down formed with annular groove 41c is individually arranged in the utility model again at 41 root of locking rod Section, so that artificial increases easy stress and deformation section.When forced rotating outer cover 40, which can be at the first time due to external force Deformation is generated, phenomenon of rupture finally occurs at this.

For capping 10, arrangement shrinkage pool that can be as shown in Figure 3-4, in order to enable to lock when assembling outer cover 40 Only the displacement action of bar 41 can avoid Kaifeng lid 10.It covers setting shrinkage pool at 10 and is also equipped with the function as positioning process hole, from And when such as covering frosted sealing surface at the lower section shaft b of extended segment 10a at 10 with frosting technology processing, it can be by machine Locating shaft is directly coaxially positioned in shrinkage pool, to reach the processing effect of benchmark.And the section that postpones of inner cover 30 needs to prolong always Vessel port a side wall is extended to, and arranges in-flanges 31 to form seam allowance cooperation between vessel port a side-walls seam allowance.

As absolute construction, the flaring of outer cover axially can postpone downwards to coat lid 30a along itself, outer cover 40 The bottom face flush of the elongated end of the bottom face and inner cover 30 of flaring, in order to cover outer cover 40, inner cover 30 and lid 30a promotes the globality of its structure.Even between outer cover 40 and outer cover can and integral structure secured to one another by glue etc., from And promote its packaging efficiency and property easy to use.The technological designs such as decoration painting can be more arranged at the top end face of outer cover 40, To play the function of further beautification the utility model.
