Bottle cap

Abstract

Disclosed herein is a bottle cap. The bottle cap includes an inner lower cap which is coupled to a bottle and has on a lower end thereof a protruding breaking part, an inner upper cap which is coupled to an upper portion of the inner lower cap and moves a push cap downwards through a screw-type fastening method when the inner upper cap is rotated, and the push cap which serves as an additive holding member and has on a bottom thereof a thin-plate-type stopper. The bottle cap includes an outer protective cap which has a support tube therein so that the inner upper cap is fitted into the support tube in such a way as to rotate along with the outer protective cap, and covers an upper end of the inner upper cap and a surface of the bottle. A frictional vibration plate rubs against a frictional plate of the outer protective cap to produce sound of friction, thus indicating a time at which an additive starts to drop into the bottle, because the thin-plate-type stopper is broken, when the inner upper cap moves the push cap down, so that the push and turn screw is disengaged from the hook screw and the inner upper cap moves up.

1 . A bottle cap, having an inner lower cap coupled to a bottle and having on a lower end thereof a protruding breaking part, an inner upper cap coupled to an upper portion of the inner lower cap and moving a push cap downwards through a screw-type fastening method when the inner upper cap is rotated, and the push cap serving as an additive holding member and having on a bottom thereof a thin-plate-type stopper, the bottle cap comprising:
 an outer protective cap having a support tube therein so that the inner upper cap is fitted into the support tube in such a way as to rotate along with the outer protective cap, the outer protective cap covering an upper end of the inner upper cap and a surface of the bottle; and   a frictional vibration plate rubbing against a frictional plate of the outer protective cap to produce sound of friction, thus indicating a time at which an additive starts to drop into the bottle, because the thin-plate-type stopper is broken, when the inner upper cap moves the push cap down, so that the push and turn screw is disengaged from the hook screw and the inner upper cap moves up.   
   
   
       2 . The bottle cap as set forth in  claim 1 , wherein a coaxial tube, serving as a straw, is axially placed on a center of the push cap, and an upper straw cover is provided on an upper end of the coaxial tube such that contents in the bottle are discharged through a center of an upper end of the inner upper cap via a straw. 
   
   
       3 . The bottle cap as set forth in  claim 1 , further comprising:
 a hole formed in an upper portion of the outer protective cap, and passing sound of friction to an exterior, the sound being made by the vibration plate when the push cap moves down and the inner upper cap moves up.   
   
   
       4 . The bottle cap as set forth in  claim 1 , wherein an upper portion of the outer protective cap comprises a separable cap which is opened so that the upper straw cover is exposed to the exterior, with the separable cap being supported at a lower edge thereof by a cap support protrusion. 
   
   
       5 . A bottle cap, having an inner lower cap coupled to a bottle and having on a lower end thereof a protruding breaking part, an inner upper cap coupled to an upper portion of the inner lower cap and moving a push cap downwards through a screw-type fastening method when the inner upper cap is rotated, and the push cap serving as an additive holding member and having on a bottom thereof a thin-plate-type stopper, the bottle cap comprising:
 an outer protective cap having a support tube therein so that the inner upper cap is fitted into the support tube in such a way as to rotate along with the outer protective cap, the outer protective cap covering the inner upper cap and a surface of the bottle; and   a frictional vibration plate rubbing against a frictional plate of the outer protective cap to produce sound of friction, thus indicating a time at which an additive starts to drop into the bottle, because the thin-plate-type stopper is broken, when the inner upper cap moves the push cap down, so that the push and turn screw is disengaged from the hook screw and the inner upper cap moves up.   
   
   
       6 . The bottle cap as set forth in  claim 5 , further comprising:
 a decorative toy, integrally fitted over an upper portion of the outer protective cap via fitting means.   
   
   
       7 . The bottle cap as set forth in  claim 6 , wherein the fitting means comprises:
 a fitting projection protruding from the toy, and having on an end thereof a hook; and   a toy fitting hole provided at a predetermined position in the outer protective cap, so that the fitting projection is fitted into the fitting hole, thus providing force for supporting the toy.   
   
   
       8 . The bottle cap as set forth in  claim 7 , wherein the fitting means comprises:
 a support hook, bent inwards from a lower end of the toy; and   a toy support groove provided at a predetermined position in the outer protective cap so that the support hook is inserted into the toy support groove.   
   
   
       9 . The bottle cap as set forth in  claim 5 , further comprising:
 a support step, provided on an inner surface of a lower end of the support tube, and seated between a lower end step, forming a lower end of an outer wall of the inner lower cap, and a tamper resistant band, thus supporting the inner lower cap.
