Abstract
The utility model relates to a bottle lid discloses a bottle lid of in -band stopper, including upper cover, low tube, inside lining and nei sai, the upper cover be equipped with the internal thread, the one end of inside lining be equipped with with the upper cover in the external screw thread that closes of thread to match, the other end of inside lining is located lower intraductal, the outer wall of inside lining with the low tube joint, interior stopper lie in the intracavity of inside lining, interior stopper is through setting up in interior snap ring beyond the great wall and inside lining joint, interior stopper have with the plug of bottleneck inner wall inflation contact, one section outer wall inflation with the bottleneck that the inside lining corresponds the plug contacts. The utility model discloses a plugging with the inflation contact of bottleneck inner wall, realize the once sealed of bottleneck, the inflation contact of rethread inside lining and bottleneck outer wall realizes the secondary seal of bottleneck, uses many times that the stopper pulls out the back for a long time, even drinks have to be spilled over, through also hardly once more through the secondary seal after once sealed, has improved the sealing performance of bottle lid greatly.
Description
Technical field
This utility model is related to a kind of bottle cap, the preferable bottle cap of especially a kind of sealing.
Background technology
Wine bottle cap in the market does not have interior plug mostly, is only single bottle cap, and bottleneck and bottle cap are hard contact,
Lead to its poor sealing, after especially bottle opens, when needing to store again, drinks are unable to strict seal, often have spilling
Phenomenon.At present, part is also had to carry the bottle cap of interior plug, it passes through clogging and bottle sealing of interior plug, but may after multiple plug
The situation of seal failure occurs, there is the possibility of drinks spilling.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bottle cap of plug in band, by changing to Bottle cap structure
Enter to improve its sealing, thoroughly avoid the probability that drinks overflow.
This utility model solves its technical problem and be employed technical scheme comprise that：A kind of band in plug bottle cap, including on lid,
Down tube, liner and Nei Sai, described on be covered with female thread, one end of described liner is provided with match with upper lid female thread outer
Screw thread, the other end of liner is located in described down tube, the outer wall of liner and described down tube clamping, and described interior plug is located at interior
The interior intracavity of lining, interior plug by snap ring beyond the Great Wall in being arranged at and liner clamping, described interior plug have with bottleneck opening's edge in
The stick harness of wall expansion contact, one section of outer wall expansion contact with bottleneck opening's edge of the corresponding stick harness of described liner.
Further, the inwall expansion contact of the liner in down tube and down tube.
Further, the external diameter of described stick harness end is less than the external diameter of root, is provided with external diameter between stick harness end and root
The changeover portion of gradual change, when filling in stick harness, this changeover portion can play guiding function, reduces the resistance that stick harness fills in bottleneck.
Further, described interior plug is bulge loop structure with respect to one end of stick harness, and the outer wall of bulge loop structure is provided with annular
Fin, described bulge loop structure passes through the inwall interference fit of fin and liner, can be consolidated in liner by this interference fit
Interior plug, so that during plug bottle cap, interior plug is unlikely to the situation occurring loosening.
Further, described liner and Nei Sai are all made using PET material.
Further, described interior plug is hollow structure.
The beneficial effects of the utility model are：（1）By clogging the inwall expansion contact with bottleneck opening's edge, realize bottleneck
Once sealing, then the outer wall expansion contact by liner and bottleneck opening's edge, realize the secondary seal of bottleneck, life-time service is repeatedly filled in
After pulling out, even if drinks have spilling, it also is difficult to after once sealing again by secondary seal, substantially increase the sealing of bottle cap
Performance；（2）The inwall expansion contact of liner and down tube also preferably ensure that the sealing of bottle cap, though have drinks from Nei Sai with
The access section of liner is overflowed, and also can be stoped by the expansion contact of liner, prevents from continuing to overflow；（3）Interior plug and liner adopt PET material
Matter is made, and compared with the PP material of existing employing, has preferable fatigue durability and rub resistance, increased service life, and PET
Wholesomeness also more preferable.
Brief description
Fig. 1 is cross-sectional view of the present utility model；
Fig. 2 is the structural representation of this utility model liner；
Fig. 3 is the structural representation of plug in this utility model；
In figure is labeled as：Cover on 1-, 2- down tube, 3- liner, 31- annular convex surface, plug in 4-, 41- snap ring, 42- stick harness,
43- changeover portion, 44- bulge loop structure, 45- fin.
Specific embodiment
With reference to specific embodiment, this utility model is described in further detail, but embodiment party of the present utility model
Formula not limited to this.
As shown in Figure 1, Figure 2 and Figure 3, of the present utility model a kind of band in plug bottle cap, including on lid 1, down tube 2, liner 3
With interior plug 4.
Described upper lid 1 is provided with female thread；One end of described liner 3 is provided with the external screw thread matching with upper lid 1 female thread,
The other end of liner 3 is located in described down tube 2, and an annular convex surface 31 and down tube 2 are passed through in the end of the liner 3 in down tube 2
Inwall expansion contact, the outer wall of liner 3 and described down tube 2 clamping；Described interior plug 4 is hollow structure, and interior plug 4 passes through setting
Snap ring 41 on interior plug 4 outer walls is connected in the interior intracavity of liner 3.
Described interior plug 4 has the stick harness 42 with the inwall expansion contact of bottleneck opening's edge, the corresponding stick harness 42 of described liner 3
One section of outer wall expansion contact with bottleneck opening's edge；The external diameter of described stick harness 42 end be less than root external diameter, stick harness 42 end with
It is provided with the changeover portion 43 of external diameter gradual change between root；Described interior plug 4 is bulge loop structure 44 with respect to one end of stick harness 42, and bulge loop is tied
The outer wall of structure 44 is provided with the fin 45 of annular, and described bulge loop structure 44 passes through the inwall interference fit of fin 45 and liner 3；Institute
The liner 3 stated and Nei Sai 4 are all made using PET material.
During use, if there being drinks to overflow between stick harness 42 and bottleneck opening's edge inwall, also can be because outside liner 3 and bottleneck opening's edge
The annular convex surface 31 of the expansion contact of wall and liner 3 is stoped with the expansion contact of down tube 2 inwall, prevents drinks from continuing to overflow
Go out, therefore, bottle cap of the present utility model has higher sealing, and the liner 3 of PET material and Nei Sai 4 also have preferably
Fatigue durability and rub resistance.
