Abstract
The utility model provides a kind of safety-type Double layer bottle cap, and comprise external bottle cap and interior bottle cap, interior bottle cap is nested in external bottle cap inside, it is characterized in that: the inner surface of described external bottle cap is provided with vertical slice; Described interior bottle cap outer surface is provided with vertical slice, and described external bottle cap is corresponding with the vertical slice on interior bottle cap, and it is protruding that the outer surface that described outer blank is leaned to one side is provided with semi-cylindrical striped.The utility model is by being provided with vertical slice at the inner surface of external bottle cap and interior bottle cap outer surface, when external bottle cap is exerted pressure inadequate, vertical slice skids and skips, interior bottle cap of namely not opening, thus plays and prevent child, prevent children from disorderly eating the effect of article in bottle.
Description
Technical field
The utility model relates to closure field, particularly a kind of safety-type Double layer bottle cap.
Background technology
When common bottle cap uses, clockwise direction is for screwing bottle cap, and anticlockwise direction is bottle cap of outwarding winding.Such bottle cap is extremely easily opened, if can be opened by bottle cap easily by children, probably eats food in bottle by mistake and causes poisoning accident.So design a kind of resistant closure come child protection safety be extremely necessary.The utility model being 201220088584.9 as number of patent application relates to a kind of resistant closure, comprise enclosing cover and madial wall establishes threaded inner cap, described enclosing cover is linked in inner cap outside, the projection that can engage is respectively equipped with on the inner peripheral surface of described enclosing cover and on the outer circumference surface of inner cap, the inner peripheral surface of described inner cap is provided with warning device, when the bottle cap that the power of the single applying conter clockwise of children can not be outwarded winding described in this utility model, warning device can send alerting signal, draws back children with fear, simultaneously number of patent application is the resistant closure that the utility model of 201320824056.X relates to the medicine bottle that a kind of children of preventing open voluntarily, be made up of enclosing cover and inner cap, the internal diameter of enclosing cover and the external diameter of inner cap are slack running fit, at cover top portion inner face, be provided with plural block card convex, outside inner cap top, be provided with plural block card convex, card convex bayonet fitting outside the card convex of cover top portion inner face and inner cap top, when opening bottle cap, must while pressing down enclosing cover rotary outer cover, after making the card convex bayonet fitting outside the card convex of cover top portion inner face and inner cap top, inner cap is driven to rotate by rotary outer cover, bottle cap can be opened, although above-mentioned two practically newly can prevent children from opening medicine bottle, but it is large to install warning device cost, complex structure, technical risk is high, not there is operability.
Summary of the invention
In order to overcome the shortcoming that above prior art exists, providing that a kind of structure is simple, cost is lower, use exercisable safety-type Double layer bottle cap, having the advantages that structure is ingenious, cost is low.
The utility model provides a kind of safety-type Double layer bottle cap, and comprise external bottle cap and interior bottle cap, interior bottle cap is nested in external bottle cap inside, it is characterized in that: the inner surface of described external bottle cap is provided with vertical slice; Described interior bottle cap outer surface is provided with vertical slice, and described external bottle cap is corresponding with the vertical slice on interior bottle cap.
The outer surface of described external bottle cap is arranged with semi-cylindrical striped projection in parallel.
Described vertical slice is semicylinder.
The utility model beneficial effect is: the utility model is by being provided with vertical slice at the inner surface of external bottle cap and interior bottle cap outer surface, when external bottle cap is exerted pressure inadequate, vertical slice on interior bottle cap and external bottle cap skids and skips, namely not open interior bottle cap, thus play and prevent child, prevent children from disorderly eating the effect of article in bottle; It is protruding that outer surface simultaneously by leaning to one side at outer blank is provided with semi-cylindrical striped, has the effect of the friction between increase and bottle cap.
Accompanying drawing explanation
Fig. 1 is part tangent plane schematic diagram of the present utility model;
Fig. 2 is horizontal section schematic diagram of the present utility model.
In figure: 1-external bottle cap, bottle cap in 2-, 3-striped is protruding, the vertical slice of 4-.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of safety double-layer bottle cap, comprises external bottle cap 1 and interior bottle cap 2, and it is inner that the female interior bottle cap 2 of tool is nested in external bottle cap 1.In the present embodiment, the outer surface of described external bottle cap 1 is arranged with semi-cylindrical striped projection 3 in parallel, has the effect of the friction between increase and bottle cap.
In the present embodiment, the inner surface of external bottle cap 1 is arranged with vertical slice 4 in parallel, interior bottle cap 2 outer surface is arranged with vertical slice 4 in parallel, vertical slice 4 is in semicylinder, vertical slice 4 on external bottle cap 1 and interior bottle cap 2 is corresponding, when external bottle cap 1 is exerted pressure inadequate, vertical slice 4 on interior bottle cap 2 and external bottle cap 1 skids and skips, namely not open interior bottle cap, thus play and prevent child, prevent children from disorderly eating the effect of article in bottle, when exerting pressure enough at external bottle cap 1, vertical slice 4 phase friction on interior bottle cap 2 and external bottle cap 1, and then bottle cap 2 rotates and opens bottle in driving.
What describe in above-described embodiment and specification sheets just illustrates principle of the present utility model and most preferred embodiment; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.
