Specific implementation mode
A kind of embodiment of bottle cap of the utility model is described further referring to figs. 1 to Fig. 4.
The inner wall of a kind of bottle cap, including lid 1, the lid 1 is equipped with the first internal thread 7 and the second internal thread 5, described
The diameter of first internal thread 7 is more than the diameter of the second internal thread 5 and the first internal thread 7 is located at the opening of lid 1, and described first
Transition screw thread 6 is equipped between internal thread 7 and the second internal thread 5, the both ends of the transition screw thread 6 are separately connected the first internal thread 7
With the second internal thread 5, interior be equipped with of the lid 1 has externally threaded flexible collar 10, spiral shell in the flexible collar 10 and first
6 screw-thread fit of line 7, the second internal thread 5 and transition screw thread, the flexible collar 10 are equipped with the location structure positioned with bottleneck 9.
When in use, the location structure in flexible collar 10 is first fixed with the positioning of the bottleneck 9 of bottle, makes flexible collar 10 not
It can move upwards and be rotated relative to bottleneck 9, then rotating cover 1, due to spiral shell in flexible collar 10 and the first internal thread 7, second
6 screw-thread fit of line 5 and transition screw thread, and flexible collar 10 will not rotate, therefore lid 1 can be moved downward along screw thread, by
It is more than the diameter of the second internal thread 5, while lid 1 moves downward, flexible collar in the diameter of the first internal thread 7 of lid mouth
10 when by transition screw thread 6, are gradually compacted, since there is flexible collar 10 certain elasticity can generate deformation, simultaneously
It is fitted close with the second internal thread 5,10 liang of end in contact banding bottlenecks 9 of final flexible collar, while the bottom surface in lid 1 contradicts bottle
Cover board 4 on mouthfuls 9, to seal bottleneck 9, when bottleneck 9 to be opened, as long as rotate backward lid 1 both can, flexible collar
10, by own resilient spread apart, act on without the holding of flexible collar 10, and location structure can both be dismantled from bottleneck 9, remaining is former
Reason with sealing bottleneck 9 when principle, in this way, 1 good appearance of lid is easy to operate, at low cost, transport when also compared with
For safety.
Embodiment 1：As depicted in figs. 1 and 2, the location structure is the spline 2 being located on the inner wall of flexible collar 10, bottle
The straight slot coordinated with spline 2 is offered on mouth 9, the top of the spline 2 is equipped with locator protrusions 13, the flexible collar 10
Bottom is equipped with the spacing ring 11 being clamped with the bottom of bottleneck 9, and there are two the splines 2 in the present embodiment and is respectively positioned in straight slot, bullet
Property 10 bottom of clip spacing ring 11 move upwards for limiting flexible collar 10, restriction protrusion is for avoiding lid 1 to lower axle
To movement, and two splines 2 are plugged in straight slot, and are contradicted respectively with the two side walls of straight slot, can limit elastic card in this way
10 rotation of hoop, while having certain extendable room again when flexible collar 10 is held tightly, this connection type is suitble to most of
Processing early period of bottle, bottle is few.
Embodiment 2：As shown in figure 4, the location structure is the spline 2 being located on the inner wall of flexible collar 10, on bottleneck 9
Offer the straight slot coordinated with spline 2, the top of the flexible collar 10 is contradicted with the bottom of bottleneck 9, principle with embodiment 1,
Difference lies in the tops of flexible collar 10 and the conflict of the bottom of bottleneck 9, and the power that such flexible collar 10 can be born is relative to implementation
1 bigger of example, flexible collar 10 are not easy deformation.
The opening of the utility model preferably lid 1 is equipped with locating ring side 8, and locating ring side 8 can be by flexible collar
10 are located in lid 1 and will not voluntarily produce, and avoid the loss of flexible collar 10.
Embodiment 3：As shown in Figure 1, the bottom surface middle part in the lid 1 is equipped with pressing projection 3, at middle part, setting compresses prominent
3 are played, frictional force is minimum when rotating cover 1, while the cover board 4 on bottleneck 9, when by middle part pressure, edge can
Voluntarily to adjust position, so that cover board 4 is more compressed with sealing ring and be bonded.
Embodiment 4：As shown in Fig. 2, the bottom surface in the lid 1 is equipped with compression ring 12, compression ring 12 can make on bottleneck 9
4 stress of cover board be more uniformly distributed and be unlikely to deform, and it is strong to compress consistent seal.
Preferably the spline 2 sets there are two and is located at the opening both ends of flexible collar 10 to the utility model, is covering
When 1 positive and negative rotation of body, stress point is all in spline 2, and the position of spline 2 determines the length of the arm of force, in flexible collar 10
Be open both ends setting spline 2, can be worked with maximum arm of force when 1 positive and negative rotation of lid, to save manpower, rotated
More laborsaving convenience when lid 1.
The bottom of the preferred flexible collar 10 of the utility model is equipped with a circle latch 14, on the side wall of the lid 1
Pin hole is offered, is equipped with bolt 15 in the pin hole, one end of the bolt 15 is between two latches 14, when flexible collar 10
When tightening completely, bolt 15 can be inserted between two latches 14, to limit the rotation of lid 1.
The above is only the preferred embodiment of the utility model, and the scope of protection of the utility model is not limited merely to
Above-described embodiment, technical solution belonging to the idea of the present invention belong to the scope of protection of the utility model.It should refer to
Go out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and
Retouching, these improvements and modifications also should be regarded as the scope of protection of the utility model.
