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:

in fig. 1 to 6, the medicine bottle for infants is composed of a bottle body 1, an inner cap 2 and an outer cap 3, and the bottle body 1 may have various structures: for example, the technical core of the infant medicine bottle lies in the transmission scheme of the inner bottle cap 2 and the outer bottle cap 3, the transmission scheme has certain directionality, certain skill is needed during operation, and the infant medicine bottle can be effectively prevented from being easily opened and is easily eaten by mistake.

In the figure, the bottle body 1 is a main structure and consists 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 mouth 103; be provided with the internal thread 201 that matches with external screw thread 104 on the inner wall of interior bottle lid 2, the top of interior bottle lid 2 is provided with skewed tooth 202 on the round, the bottom of interior bottle lid 2 is provided with straight-tooth 203 under the round, bottle lid 2 is including the suit of outer bottle lid 3, the last inner wall of outer bottle lid 3 is provided with round and last skewed tooth 202 complex down skewed tooth 301, the inside turn-ups in bottom of outer bottle lid 3 forms spacing collar 302, be provided with round and straight-tooth 203 complex straight-tooth groove 303 down on the spacing collar 302.

Specifically, clearance fit is adopted between the outer wall of the inner bottle cap 2 and the inner wall of the outer bottle cap 3, and the inner bottle cap 2 and the outer bottle cap 3 can flexibly rotate and cannot be driven under the condition that upper and lower driving teeth are not considered.

It should be noted that the outer wall of the inner bottle cap 2 and the outer bottle cap 3 are generally made of plastics, and because plastics have certain shaping and elasticity, the inner bottle cap 2 is easily installed inside the outer bottle cap 3 through the opening of the outer bottle cap 3. The spacing ring 302 can be integrally formed by using a mold, or can be fixed at the bottom of the outer bottle cap 3 by using a separate bonding method, as shown in fig. 5.

It should be further noted that the shapes of the upper helical teeth 202 and the lower helical teeth 301 are both right triangles, the oblique sides of the upper helical teeth 202 and the lower helical teeth 301 are arranged oppositely, and unidirectional transmission can be achieved between the upper helical teeth 202 and the lower helical teeth 301. The maximum distance between the top surface of the limiting ring 302 and the bottom surface of the lower straight tooth 203 is L, and the numerical value of L is greater than the sum of the heights of the upper helical tooth 202 and the lower helical tooth 301, in this embodiment, the heights of the upper helical tooth 202 and the lower helical tooth 301 are both H, that is, L is greater than 2H, so as to prevent the top surface of the limiting ring 302 from contacting the lower straight tooth 203 when the inclined surfaces of the upper helical tooth 202 and the lower helical tooth 301 slide, and mistakenly fix the inner bottle cap and the outer bottle cap.

In this embodiment, a retaining ring 105 is further disposed on the bottle neck 102, and the retaining ring 105 is designed to avoid excessive downward movement of the bottle cap, so that the stress on the internal gear and the thread is too large, and the retaining ring can be omitted in practical application.

The specific working process is as follows:

1) when the outer closure is not subjected to a lifting force: the outer bottle cap 3 naturally droops under the action of gravity, and at the moment, the inner bottle cap and the outer bottle cap can only be driven by helical teeth. In the embodiment, the upper helical teeth 202 and the lower helical teeth 301 are in right-angled triangle shapes, when the outer bottle cap 3 rotates clockwise, the right-angled edges of the upper helical teeth 202 and the lower helical teeth 301 are abutted, and the outer bottle cap 3 can drive the outer bottle cap 2 to rotate, so that the bottle cap is mounted; when the outer bottle cap 3 rotates anticlockwise, the inclined surfaces of the upper inclined teeth 202 and the lower inclined teeth 301 are in contact with each other, transmission cannot be completed between the inclined surfaces, the outer bottle cap 3 can only be lifted and then rotates anticlockwise independently, and the bottle cap cannot be detached by rotating external force.

2) When the outer bottle cap is subjected to lifting force: outer bottle lid 3 upwards removes, at this moment, go up skewed tooth 202 and lower skewed tooth 301 separation, but the straight tooth groove 303 of outer bottle lid 3 and the lower straight-tooth 203 interconnect of interior bottle lid, at this moment, external force can transmit to interior bottle lid 2 through outer bottle lid 3, bottle lid 2 and bottleneck 102's relative rotation in the realization, realize the dismantlement of bottle lid, connect smoothly with lower straight-tooth 203 in order to realize straight tooth's groove 303, can set up the guide inclined plane in the both sides of straight-tooth 203 down, be convenient for conveniently get into straight tooth's groove 303.

This infant's medicine bottle simple structure, convenient to use, the installation that the adult realized the bottle lid through rotary motion, and the rethread is carried and is carried rotary motion and realize the dismantlement of bottle lid. The structure can be widely applied to the field of medicine, health care products and nutriment containers, and solves the technical problems of mistaken opening and mistaken taking of infants.

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.
