Detailed description of the invention
Below with reference to the accompanying drawings and in conjunction with the embodiments to this utility model it is described in detail.It should be noted that In the case of not conflicting, the feature in following embodiment and embodiment can be mutually combined.
See Fig. 1, the bottle cap in one of them embodiment of this utility model mainly by interior plug 10, bead 20, Check valve 30, beer discharging nozzle 40, fixed cover 50 and enclosing cover 60 form.
Described in Fig. 1-3, described interior plug 10 includes the interior plug main body 12 that can be inserted in bottleneck 90, from interior The circular convex shoulder 16, from convex shoulder 16 upper surface vertically that plug main body 12 upper end edge extends radially outwardly Upwardly extending convex cervical region 18 and be arranged at the sealing ring 14 at the upper end open of interior plug main body 12.This reality The interior plug main body 12 executed in example is step-like, it enlarged diameter section 12a including top and the reduced diameter section of bottom 12b, the external diameter of described enlarged diameter section 12a is interference fit with the internal diameter of described bottleneck 90, in being possible to prevent Plug main body 12 is rocked, and simultaneously works as the effect sealed, the external diameter of described reduced diameter section 12b and described bottleneck 90 Internal diameter be matched in clearance, to facilitate, interior plug main body 12 is inserted in bottleneck 90.Convex shoulder 16 and bottleneck 90 The cooperation face coordinated is provided with at least one annular seal tooth 16b, to fill between 10 and bottleneck 90 in improving Sealing effectiveness.The upper surface of convex shoulder 16 is provided with the first ending tendon transfer of some circumferentially spaced arrangements 16a.The inwall of described convex cervical region 18 is provided with the axially extended convex tendon of some circumferentially spaced arrangements 18a.Sealing ring 14 inwardly and obliquely protrudes from the upper end inwall of described interior plug main body 12, and sealing ring 14 Upper surface be arc, to increase sealing surface.
In conjunction with 1,4-5 is as it can be seen, described beer discharging nozzle 40 includes outer muzzle 44, is positioned at outer muzzle 44 If interior muzzle 42 and between outer muzzle 44 and interior muzzle 42 for involvement that both are linked together Connecing muscle 46, outer muzzle 44 is fixing, and to be inlaid in the convex cervical region 18 of interior plug 10 outside, with realize beer discharging nozzle 40 with Sealing between interior plug 10;It is provided with external screw thread 44a, it is preferable that external screw thread on the outer peripheral face of outer muzzle 44 44a is double thread.Owing to the external screw thread 44a of outer muzzle 44 generally uses both sides Laser Processing to form, In order to prevent junction between the screw thread of both sides from there is dislocation, there is plane the both sides of outer muzzle 44, by external screw thread 44a is cut into noncontinuity screw thread;There is outward extending bulge loop 48 lower end of outer muzzle 44, outer muzzle 44 Be provided with the second ending tendon transfer 44b of some circumferentially spaced arrangements on lower surface, the second ending tendon transfer 44b and First ending tendon transfer 16a can increase the frictional force between beer discharging nozzle 40 and interior plug 10, when preventing from opening enclosing cover, Beer discharging nozzle 40 relatively rotates with interior plug 10;Through hole 42a is arranged at the top of interior muzzle 42.
Two beades about 20 are loaded in described interior plug main body 12 overlappingly, are used for sealing described interior plug main The lower ending opening of body 12.
In conjunction with 1,6 as it can be seen, described check valve 30 be loaded on movably described convex cervical region 18 with described go out In the space that wine mouth 40 is formed, check valve 30 includes the valve body 34 of upper end closed, is positioned at outside valve body 34 Outer cylinder body 36 and the connecting portion 38 that the lower end of valve body 34 is connected with the lower end of outer cylinder body 36, described outer cylinder body The diameter of a circle that the external diameter of 36 inner face less than some described convex tendon 18a is surrounded, with to outer cylinder body 36 To guide effect, the end face of valve body 34 is provided with groove 34a, when check valve 30 is transported in convex cervical region 18 Time dynamic, utilize convex tendon 18a that outer cylinder body 36 is guided, during pouring, interior muzzle 42 insert valve body 34 with Between outer cylinder body 36, it is also possible to check valve 30 is guided, so can strengthen check valve 30 axially-movable Stability, prevents excessive swing.It is provided with close with the inverted cone that sealing ring 14 coordinates on connecting portion 38 Front cover 32, when check valve 30 compresses, is formed between sealing surface 32 and sealing ring 14 and reliably seals.And by Being inverted cone sealing surface 32 in sealing ring 14, sealing ring 14 tilts obliquely, even if because being applied to check valve During power deficiency on 30, also ensure that sealing ring 14 reliably seals with sealing surface 32.
As it is shown in fig. 7, described fixed cover 50 is tubular structure, the upper end of fixed cover 50 has and extends internally Splenium 52, the fixing outside being inlaid in bottleneck 90 of fixed cover 50, the splenium 52 of fixed cover 50 upper end is pressed in On the bulge loop 48 of beer discharging nozzle 40, the lower surface making described beer discharging nozzle 40 is tight with described convex shoulder 16 upper surface Patch, prevents wine leaking.
In conjunction with 1,8-9 as it can be seen, enclosing cover 60 inner peripheral surface on be provided with and the external screw thread on beer discharging nozzle 40 The female thread 62 that 44a coordinates, female thread 62 is double thread, and the middle part of the inner top surface of enclosing cover 60 has along axle To the push rod 64 extended, when enclosing cover 60 screws in beer discharging nozzle 40, push rod 64 is through interior muzzle 42 top Through hole 42a inserts in the groove 34a on valve body 34 end face of check valve 30, makes sealing surface 32 and sealing ring 14 are close to, and play sealing function.The inner top surface of enclosing cover 60 has sealing ring 66, and the external diameter of sealing ring 66 is with outer The internal diameter interference fit of muzzle 44, plays sealing function, prevents wine leaking.
Figure 10 is the use state diagram of the bottle cap in this utility model embodiment.As shown in Figure 10, interior plug 10 Interior plug main body 12 insert in bottleneck 90, the fixing outside being inlaid in bottleneck 90 of fixed cover 50, fixed cover The splenium 52 of 50 upper ends is pressed on the bulge loop 48 of beer discharging nozzle 40, thus beer discharging nozzle 40, interior plug 10 is fixed It is arranged on bottleneck 90.
Embodiment described above only have expressed several embodiments of the present utility model, its describe more concrete and In detail, but therefore can not be interpreted as the restriction to this utility model the scope of the claims.It should be pointed out that, For the person of ordinary skill of the art, without departing from the concept of the premise utility, it is also possible to Making some deformation and improvement, these broadly fall into protection domain of the present utility model.
