Abstract

The utility model relates to a safety bottle cap for encapsulating bottles which are not in a condition for children to open, such as medicines, chemicals, agricultural chemicals, etc. The safety bottle cap is composed of the bottle cap core of a screw port and a safety bottle cap sleeve. An annular groove on the edge of the safety bottle cap sleeve is matched and sheathed with the annular conical surface of the bottle cap core. The top part of the bottle cap core is evenly distributed with pawls. The bottom of the bottle cap sleeve is also correspondingly and evenly distributed with pawls, and one side of each pawl is provided with an oblique plane. The bottle cap sleeve can rotate according to a screwing direction on the bottle cap core. When in use, the bottle cap sleeve is pressed down, the pawls of the bottle cap sleeve and the bottle cap core are engaged, and then the bottle cap is unscrewed. The utility model can effectively prevent little children form drinking harmful substances, and the safety bottle cap is safe and convenient.

Description

Safety bottle cap

The utility model relates to a kind of resistant closure, belongs to household goods.

Present commercially available various container finishs, mostly being spiral seals, the bottle cap mode of outwarding winding has only a kind of, and a lot of medicines, insecticide, cleaning agent of entering family etc. should not children open voluntarily, because of children's situation that the objectionable impurities container leads to a disaster of outwarding winding without authorization happens occasionally.

The object of the present invention is to provide a kind of resistant closure, children are difficult for outwarding winding voluntarily, but can rotate naturally, thereby wrongly take when having avoided children to play, misapply chemical and have an accident.

The technical solution of the utility model is achieved in that resistant closure is made up of screw thread mouth bottle cap core and resistant closure cover, and the edge that bottle cap overlaps has annular groove to cooperate socket with the annular conical surface of bottle cap core.The uniform ratchet in bottle cap core top, the bevelled ratchet of the bottle cap cover also corresponding uniform side in bottom surface, the bottle cap cover can rotate by the direction of outwarding winding on the bottle cap core, is as good as with general bottle cap when screwing bottle cap, depress the bottle cap cover when outwarding winding bottle cap, the bottle cap cover and the ratchet engagement of bottle cap core can be outwarded winding.
