Abstract

The utility model relates to a safety lid. The utility model is characterized in that the safety lid is provided with an external lid, wherein, an internal lid which can freely rotate in a single direction is embedded in the external lid. After the safety lid is unsealed, when the safety lid is screwed off, if the external lid is not pressed downward, the safety lid can not be screwed off. Thus, the utility model can prevent children from opening a bottle lid to cause accidents.

Description

Safety cap

The utility model relates to the lid that is used for bottleneck.

At present, all useful bottles such as commercially available food, medicine, chemical products are done packing, these bottles all have only a lid, one after this lid unpacking, open for the second time and just be easy to, particularly child's curiosity is heavy, sees that the adult opens also just and then learning like this to open, and just eat the thing in the bottle, cause the accident of poisoning also of common occurrence.

The purpose of this utility model provides a kind of lid that contains inner cap, after unpacking, is not to twist covered son to pressing down enclosing cover, can prevent that like this child from stealing the uncork lid and cause the accident.

Technical solution of the present utility model is an enclosing cover is arranged, but enclosing cover to be embedded with a folk prescription to the inner cap that rotates freely.

The caping inner surface periphery of the above enclosing cover has and is no less than a pair of protruding, recessed tooth.

The caping inner surface periphery of enclosing cover of the present utility model can have nine pairs of protruding, recessed teeth.

In the circle that protruding, the recessed tooth in the caping surface of the above enclosing cover forms, there are three one side to be fixed in outer covering, the shell fragment of the circular arc that has scratched on one side, the shell fragment of three circular arcs are equidistantly and by central angle all to distribute with the center of circle, and the shell fragment of three circular arcs has been scratched by same hand of rotation.

There is the bayonet socket of a circle projection inboard, the utility model enclosing cover skirt base.

Have on the hd top face circumference in the above the utility model and be no less than a pair of concave, convex tooth.

Concave, convex tooth in described in the utility model on the hd top face circumference has nine pairs.

The thread that three bar shapeds are arranged in the circle that hd top face circumference concave, convex tooth forms in above the utility model, one side of thread is vertical surface, another side is the inclined-plane, and three threads be oriented same hand of rotation, three threads all are located on the radius of central angle of five equilibrium.

Outside face nearly lower end in the utility model inner cap shirt rim has the corresponding protruding bayonet socket of a circle and enclosing cover.

The utility model inner cap shirt rim inside face has the screw thread that screws bottleneck.

The utility model is when screwing bottle cap, and three circular arc shell fragments in the outer lid support the vertical surface of three threads of inner cap, and clockwise direction screws bottle cap.When opening bottle cap, enclosing cover is depressed, and the peripheral shaggy tooth of inside and outside lid is engaged, the anticlockwise direction bottle cap of outwarding winding.Do not depress enclosing cover when opening bottle cap, inside and outside lid periphery shaggy tooth does not engage, and anticlockwise direction is opened bottle cap and do not opened, and has only the shell fragment reversing sense to contact with the inclined-plane of thread and sends sound.Is to be difficult to take out after inner cap of the present utility model embeds in the enclosing cover, this mainly is that the bayonet socket of lower end, inner cap shirt rim snaps in the bayonet socket of enclosing cover shirt rim inside lower end again.Under the thread vertical surface of the present utility model pit can also be arranged, more help shoring of enclosing cover circular arc shell fragment.

The utility model has the advantages that in the time will twisting the lid off, is not to twist covered son to pressing down enclosing cover, can prevent that like this child from stealing the uncork lid and cause the accident,

Below in conjunction with accompanying drawing embodiment of the present utility model is described:

Fig. 7 inside and outside lid running condition scheme drawing of the present utility model.

Shown in Fig. 1,2,3,4,5,6, the utility model has an enclosing cover, but enclosing cover is embedded with a folk prescription to the inner cap that rotates freely, the caping inner surface periphery of enclosing cover has and is no less than a pair of double wedge 2 and recessed tooth 3, the concave, convex tooth can be nine pairs, in the circle that the lid basal surface convex and concave teeth of enclosing cover forms, there are three one side to be fixed in outer covering, the shell fragment 1 of the circular arc that has scratched on one side, the shell fragment 1 of three circular arcs is equidistantly and by central angle all to distribute with the center of circle, and the shell fragment 1 of three circular arcs is to have scratched by same hand of rotation.There is the bayonet socket 4 of a circle projection inboard, enclosing cover skirt base, have on the interior hd top face circumference and be no less than a pair of concave, convex tooth, shaggy tooth on the interior hd top face circumference can have nine pairs, the thread 5 that three bar shapeds are arranged in the circle that the recessed tooth 7 of interior hd top face circumference, double wedge 6 form, one side of thread 5 is vertical surface, another side is the inclined-plane, and three threads be oriented same hand of rotation, three threads all are located on the radius of central angle of five equilibrium, the inner cap shirt rim nearly lower end of outside face has the corresponding protruding bayonet socket 7 of a circle and enclosing cover, and inner cap shirt rim inside face has the screw thread 8 that screws bottleneck.
