Safety cap

Abstract

The present invention relates to a safety cap which is screwed onto an upper portion of a container body in which contents are stored so as to open/close the outlet of a container. The safety cap of the present invention is configured such that, when an outer cap rotates in a closing direction, a stopper protrusion of the outer cap is brought into contact with a protrusion of an inner cap and the outer cap and the inner cap rotate together, thus enabling the container to be easily closed and automatically capped during a manufacturing process.

1 . A safety cap which is screwed to the top of a container body storing contents and opens and closes a discharge part of the container, comprising:
 an inner cap which surrounds the top of the container body and has threads on an inner surface for a thread engagement and a plurality of regularly spaced protrusion pieces formed at the top of the same and a rotation indication part that a user holds and rotates, formed at the lower portion of the same; and   an outer cap which is engaged surrounding the inner cap, an engaging protrusion protruding downward from an inner portion of its top and fixed by the protrusion piece when it rotates in the closing direction for thereby rotating the inner cap, a cap fixing strap provided at its lower portion and engaged surrounding the rotation indication part in a parting-possible way.   
     
     
         2 . The cap of  claim 1 , wherein the engaging protrusion has a gentle slope formed from one side to the other direction and moves pressurizing the top of the protrusion piece by the slope of the engaging protrusion when the outer cap rotates in the opening direction. 
     
     
         3 . The cap of  claim 2 , wherein the protrusion piece is made from a flexible material so that it can move in the downward direction by the pressurizing of the engaging protrusion when the outer cap rotates in the opening direction and then can return. 
     
     
         4 . The cap of  claim 1 , wherein the cap fixing strap comprises:
 an engaging part which is engaged surrounding the rotation indication part of the inner cap; and   a handle part formed at a front end portion of the engaging part.   
     
     
         5 . The cap of  claim 1 , wherein a slip prevention protrusion is formed at an outer surface of the rotation indication part.
