Abstract

The utility model relates to a double-pane bottle cap, comprising an inner cap and an outer cap, which is characterized in that the outer cap can be napped on the inner cap. A row of act-downwards teeth is arranged on the outer top surface of the inner cap and a row of act-upwards teeth is arranged on the inner top surface of the outer cap. The two rows are arrayed crisscross correspondingly to each other. The bottle cap can be opened after the teeth on the upper cap and the lower cap buckle by pressing the upper cap when using, therefore the utility model has the advantages of preventing the child from opening the bottle easily and increasing the safety when using.

Description

Double layer bottle cap

Technical field

The utility model relates to a kind of bottle cap, relates in particular to the Double layer bottle cap of the inside and outside lid of a kind of tool.

Background technology

In China, the article that a lot of medicines arranged or should not children take are bottled, and the structure of bottle cap is very simple, only is that individual layer is spiral, and promptly the bottle cap inner ring is provided with screw thread, can directly be fastened on the bottleneck by spiral way, be easy to just can be turned on by children, improper if some is contained with the bottle placement location of should not children taking, the words of being taken and eating by mistake by children, will cause adverse consequences, even cause danger.

The utility model content

Technical problem to be solved in the utility model is, a kind of structure improved bottle cap is provided, and it can prevent that children from opening bottle cap easily and getting the article that held in the food bottle by actv..

The technical scheme that the utility model addresses the above problem is: design a kind of Double layer bottle cap, form by inner cap and enclosing cover, it is characterized in that, this inside and outside lid can fasten mutually, the outer end face of this inner cap is provided with down the effect tooth, the inner top surface of enclosing cover is provided with the effect tooth, and this two rows effect tooth is arranged relatively.

The outside face of described inner cap is provided with the buckle limit.

The inside face of described enclosing cover is provided with flange.

Be not provided with screw thread on the inside face of described enclosing cover.

In the described two rows effect tooth, the flank of tooth that has a row to act on tooth is a bevelled, and the flank of tooth that another row acts on tooth is a level.

The side slightly inclined of described inner cap.

The diameter on described buckle limit is slightly less than the diameter of described flange.

The Double layer bottle cap that the utility model provides, by adopting the mode of exterior and interior cover combination, actv. has solved the safety problem that conventional bottle cap exists.Further the utility model is described below in conjunction with drawings and embodiments.

The specific embodiment

Please consult Fig. 1 and Fig. 2 together, the inner top surface of the enclosing cover 1 of the utility model Double layer bottle cap is provided with a plurality of effect of going up teeth 2 to lower convexity, it is spaced at circumferencial direction should going up that effect tooth 2 has horizontal surface and should go up effect tooth 2, and the inside face circumference of this enclosing cover 1 is provided with flange 3.

Please consult Fig. 3 and Fig. 4 together, the outer end face of the inner cap 4 of the utility model Double layer bottle cap is provided with a plurality of following effect teeth 5 that raise up, this time effect tooth 5 has inclined surface and this time effect tooth 5 also is spaced at circumferencial direction, side 7 slightly inclineds of this inner cap 4, the outside face circumference of this inner cap 4 is provided with buckle limit 6.

See also Fig. 5, the following effect tooth 5 of inner cap 4 is staggered corresponding the arrangement with the effect of the going up tooth 2 of enclosing cover 1, promptly one acts on the positions, interval that tooth 5 can be engaged to two adjacent upward effect teeth 2 down, equally, go up effect tooth 2 for one and also can be engaged to two positions, interval between the adjacent following effect tooth 5, and, should act in the tooth upper and lower two rows, the flank of tooth that has a row to act on tooth is a level, the flank of tooth that another row acts on tooth then is a bevelled, in the present embodiment, the flank of tooth of the following effect tooth 5 of inner cap 4 is bevelleds, and the flank of tooth of the effect of the going up tooth 2 of enclosing cover 1 is a level.

The utility model Double layer bottle cap in use, need earlier inner cap 4 to be pressed in the enclosing cover 1, because being the space, arranges in the following effect tooth 5 of going up effect tooth 2 and inner cap 4 of enclosing cover 1, when enclosing cover 1 stressed when pressing down, the effect of the going up tooth 2 of enclosing cover 1 can engage mutually with the following effect tooth 5 of inner cap 4, and rotary outer cover 1 just can drive inner cap 4 this Double layer bottle cap is taken off at this moment.When enclosing cover 1 is not subjected to downward pressure, owing to exist certain height poor between enclosing cover 1 and the inner cap 4, just be difficult to accurate engaging between last effect tooth 2 and the following effect tooth 5, this moment as if rotary outer cover 1 just, will cause enclosing cover 1 to dally in inner cap 4 outsides, inner cap 4 is the situation of corresponding rotation thereupon not but, thereby bottle cap can't be taken off, simultaneously, because the diameter on slightly larger in diameter buckle limit 6 on inner cap 4 outside faces of enclosing cover 1 inside face upper flange 3, even last effect tooth 2 with can not accurately engage between the effect tooth 5 down, enclosing cover 1 also can not come off from inner cap 4, and inner cap 4 is touched by staff.

The utility model Double layer bottle cap can prevent effectively that children from opening bottle cap easily, has strengthened the safety member that uses.
