Safety buckling cover

Abstract

A safety buckling cover includes an outer frame installed at an upper side of the cover; a frame top of the outer frame being installed with a movable unit; the movable unit being approximately vertical to the frame top and being formed with a push portion at one side thereof; each of two lateral sides of the movable unit being installed with a buckle; the two buckles tightly clamping the movable unit from the two lateral sides thereof; a buckle including two hook blocks; each of the hook blocks having a respective protruding edge resisting against the movable unit for safely clamping the movable unit to prevent the movable unit from releasing out; the front inner lateral side of each hook block having an inclined surface for guiding the movable unit to enter into a space between the two hook blocks.

1 . A safety buckling cover capable of being buckled into a cup; the cover comprising:
 an outer frame installed at an upper side of the cover; a frame top of the outer frame being installed with a movable unit; a central portion of the cover being formed with a cover surface;   the movable unit being approximately vertical to the frame top and being formed with a push portion at one side thereof; the backside of the movable unit being opposite to the push portion; the movable unit having two lateral sides;   each of two lateral sides of the movable unit being installed with a buckle; the two buckles tightly clamping the movable unit from the two lateral sides thereof; a breaking line being formed between a lower side of the backside of the movable unit and the frame top of the cover; by the breaking line, the movable unit can separate from the frame top of the cover to form with a drinking opening;   a buckle including two hook blocks; each of the hook blocks having a respective protruding edges resisting against the movable unit for safely clamping the movable unit to prevent the movable unit from releasing out; the front inner lateral side of each hook block having an inclined surface for guiding the movable unit to enter into a space between the two hook blocks; the two hook blocks protruding from the cover surface; and   a rib being a semi-round recess for enhancing the structure of the cover; and the cover surface being also formed with a vent for venting air.   
   
   
       2 . The safety buckling cover as claimed in  claim 1 , wherein a gap is formed between the buckle and the outer frame. 
   
   
       3 . The safety buckling cover as claimed in  claim 1 , wherein one end of each hook block protrudes from a cover surface of a cover and another end of the hook block is in a recess in a cover surface of the cover. 
   
   
       4 . The safety buckling cover as claimed in  claim 1 , wherein the hook blocks protrude from a cover surface of the cover. 
   
   
       5 . The safety buckling cover as claimed in  claim 1 , wherein each of the two hook blocks is located in a recess of the cover surface. 
   
   
       6 . The safety buckling cover as claimed in  claim 1 , wherein the drinking opening is as the same elevation as that of an upper surface of the frame top. 
   
   
       7 . The safety buckling cover as claimed in  claim 1 , wherein the drinking opening has an elevation different from that of the outer frame. 
   
   
       8 . The safety buckling cover as claimed in  claim 1 , wherein the cover surface also formed with a vent for venting air.
