The terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

The invention is further explained according to the attached drawings:

as shown in fig. 1 to 5, the medicine bottle includes a bottle body 1, an inner cap 2 and an outer cap 3, and a compression spring 4, wherein the bottle body 1 may include various conventional structures, such as: round bottles, square bottles, etc. In this embodiment, the bottle body 1 is composed of a bottle cavity 101 and a bottle neck 102, and the bottle neck 102 is provided with an external thread 104 at a position close to a bottle opening 103; an inner thread 201 matched with the outer thread 104 is arranged on the inner wall of the inner bottle cap 2, and a follow-up inclined plane 202 is arranged on the outer wall of the inner bottle cap 2; the outer bottle cap 3 is sleeved on the inner bottle cap 2, a transmission inclined plane 301 which is matched with the follow-up inclined plane 202 to work is arranged on the inner wall of the outer bottle cap 3, and the bottom of the outer bottle cap 3 is flanged inwards to form a limiting ring 302; the pressure spring 4 is arranged in a cavity formed by the inner wall of the outer bottle cap 3 and the top surface of the inner bottle cap 2, the bottom of the bottle neck 102 is provided with a retaining ring 105, and the retaining ring 105 prevents the bottle cap from excessively moving downwards, so that internal devices and threads are excessively stressed.

Specifically, under the action of the pressure spring 4, the transmission inclined plane 301 of the outer bottle cap 3 is separated from the follow-up inclined plane 202 of the inner bottle cap 2, and after downward external force overcomes the elastic force of the pressure spring 4, the transmission inclined plane 301 and the follow-up inclined plane 202 are contacted to realize the mutual connection of the inner bottle cap 2 and the outer bottle cap 3.

As shown in fig. 1 and 2, the driving bevel 301 and the following bevel 202 are both annular bevels, which may be integrally formed with the bottle cap or may be bonded at a later stage. Specifically, the contour of the annular inclined surface includes not only an inclined surface but also a plane, as shown in fig. 3, the transmission inclined surface 301 is an inclined surface and a plane in sequence from bottom to top, and the connection is transited by a chamfer. The follow-up inclined plane 202 is an inclined plane and a plane from top to bottom in sequence, and the connection part is in transition by using a chamfer. In special applications, an elastic material, such as a rubber ring, may be added at the interface between the driving bevel 301 and the follower bevel 202 to increase the friction. In the figure, the follow-up inclined plane 202 is arranged between the transmission inclined plane 301 and the limiting ring 302, and when the inner bottle cap 2 is installed on the bottle body 1, the moving distance of 1-2cm should be ensured between the follow-up inclined plane 202 and the transmission inclined plane 301.

It should be noted that, clearance fit is adopted between the outer wall of the inner bottle cap 2 and the inner wall of the outer bottle cap 3.

As shown in fig. 4, the stop collar 302 and the driving bevel 301 are not integrated with the outer bottle cap 3 and are later bonded. The inboard of spacing collar 302 is the inclined plane design, and the inclined plane design is used for leading interior bottle lid 2 to get into outside bottle lid 3 inside, and under general condition, interior bottle lid 2 all adopts plastics with outside bottle lid 3, because plastics possess certain deformability, consequently inside and outside bottle lid of installation that can be convenient. Specifically, the inner opening of the stop collar 302 is slightly smaller than the outer contour of the follow-up slope 202.

The specific working process is as follows:

1 when the outer bottle cap 3 is not pressed: the outer bottle cap 3 and the inner bottle cap 2 are in clearance fit, so that mutual rotation is not influenced, and the bottle cap belongs to a free state.

2 when the outer bottle cap 3 is pressed: the outer bottle cap 3 moves downward, and after moving a certain distance, the transmission inclined plane 301 starts to contact and connect with the following inclined plane 202. Along with moving down the distance increase, frictional force is also increasing, and at this moment, for the solid fixed connection state between outer bottle lid 3 and the interior bottle lid 2, external force can transmit to interior bottle lid 2 through outer bottle lid 3, realizes the relative rotation of interior bottle lid 2 and bottleneck 102, accomplishes the dismantlement or the installation of bottle lid.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention in its corresponding aspects.
