Abstract

This utility model relates to a kind of safety lock medicine bottle, comprise bottle cap, bottleneck, safety lock, have upper and lower two contrary female threads in described bottle cap, upper end female thread is right-handed thread, lower end female thread is left hand thread, and upper end internal thread diameter is less than lower end internal thread diameter; Described bottleneck has upper and lower two contrary external screw threads, and the upper external screw thread of bottleneck is right-handed thread, and lower end external screw thread is left hand thread; Described safety lock has internal and external screw thread, and internal and external screw thread is left hand thread; Described bottle cap upper end female thread coordinates with bottleneck upper external screw thread, and described bottle cap lower end female thread coordinates with the external screw thread of safety lock, the screw-internal thread fit of described bottleneck lower end external screw thread and safety lock.This utility model utilizes above positive and negative opposite threads self-locking performance and safety lock structure and bottle cap identical anti-skidding lines, solves the problem of the single rotation direction open bottle cover of child, reduces the generation that child eats medicine accident by mistake.

Description

Safety lock medicine bottle

Technical field

The utility model relates to a kind of safety lock medicine bottle, especially a kind of safe medicine bottle of threaded lock.

Background technology

Existing bottle structure is simple, and child easily rotates according to a certain fixed-direction, opens medicine bottle, easily causes the tragedy eating medicine by mistake, and therefore invention one can not easily allow child open, and adult's medicine bottle easy to use is particularly important.

Chinese patent 200810044760.7 discloses one " bidirectional safe medicine bottle ", this patent utilization bottleneck, between shoulder and body, screw thread cooperatively interacts relation, just propose double screw protection in the same way, after child turns on a screw thread, probably turn on and oppositely turn on second, cause whole design dangerous.

Summary of the invention

This utility model to solve the deficiencies in the prior art, and provide a kind of safety lock medicine bottle.

This utility model is achieved through the following technical solutions:

A kind of safety lock medicine bottle, comprise bottle cap, bottleneck, safety lock, have upper and lower two contrary female threads in described bottle cap, upper end female thread is right-handed thread, and lower end female thread is left hand thread, and upper end internal thread diameter is less than lower end internal thread diameter; Described bottleneck has upper and lower two contrary external screw threads, and the upper external screw thread of bottleneck is right-handed thread, and lower end external screw thread is left hand thread; Described safety lock has internal and external screw thread, and internal and external screw thread is left hand thread; Described bottle cap upper end female thread coordinates with bottleneck upper external screw thread, and described bottle cap lower end female thread coordinates with the external screw thread of safety lock, the screw-internal thread fit of described bottleneck lower end external screw thread and safety lock.

After tightening described bottle cap, the distance between described bottle cap lower surface to bottle upper surface is the twice of lower surface to bottle upper surface distance of safety lock.Identical anti-skidding lines are provided with outside described bottle cap and safety lock.

The beneficial effects of the utility model are:

After safety lock structure screws clockwise; bottle cap is firmly connected in one with body; open bottle cap; need first to screw off safety lock structure counterclockwise, safety lock structure is separated completely with bottle cap lower end screw thread, another mistake hour hands rotary bottle cover ability open bottle cover; more there is safety than traditional medicine bottle; have good protective measure for what be in child's stage, and for adult, method is easy to grasp and use.

Detailed description of the invention

Below in conjunction with accompanying drawing and embodiment, the utility model is described in further detail.

As shown in Figures 1 to 4, a kind of safety lock medicine bottle, comprises bottle cap 1, bottleneck 2, safety lock 4, bottle 7.

Bottle cap 1(Fig. 2) there are upper and lower two contrary female threads, upper end female thread is right-handed thread, and lower end female thread is left hand thread, and upper end internal thread diameter is less than lower end internal thread diameter.Bottleneck 2(Fig. 4) there are upper and lower two contrary external screw threads, wherein, upper external screw thread is right-handed thread, and lower end external screw thread is left hand thread, and upper external screw thread diameter is less than lower end external thread diameter.Safety lock 4(Fig. 3) be inside and outside be left hand thread.Bottle cap 1 upper end female thread and bottleneck 2 upper external screw thread coordinate, and bottle cap 1 lower end female thread and safety lock 4 external screw thread coordinate, bottleneck 2 lower end external screw thread and safety lock 4 screw-internal thread fit.

After tightening described bottle cap 1, the distance between bottle cap 1 lower surface 3 to bottle upper surface 6 is the twice of lower surface 5 to bottle upper surface 6 distance of safety lock.Identical anti-skidding lines 8 are provided with outside bottle cap 1 and safety lock 4.

When opening bottle cap 1, need first counterclockwise to be rotated by safety lock 4, end face 5 is overlapped with end face 6, and then is rotated counterclockwise bottle cap 1, bottle cap 1 is just opened.

Claims

1. a safety lock medicine bottle, comprise bottle cap (1), bottleneck (2), safety lock (4), it is characterized in that: there are in described bottle cap (1) upper and lower two contrary female threads, the upper end female thread of bottle cap (1) is right-handed thread, lower end female thread is left hand thread, and upper end internal thread diameter is less than lower end internal thread diameter; Described bottleneck (2) has upper and lower two contrary external screw threads, and the upper external screw thread of bottleneck (2) is right-handed thread, and lower end external screw thread is left hand thread; Described safety lock (4) has internal and external screw thread, and internal and external screw thread is left hand thread; Described bottle cap (1) upper end female thread coordinates with bottleneck (2) upper external screw thread, described bottle cap (1) lower end female thread coordinates with the external screw thread of safety lock (4), the screw-internal thread fit of described bottleneck (2) lower end external screw thread and safety lock (4).

2. safety lock medicine bottle according to claim 1, it is characterized in that: after tightening described bottle cap, the distance between described bottle cap (1) lower surface (3) to bottle upper surface (6) is the twice of lower surface (5) to bottle upper surface (6) distance of safety lock.
