Straw cup lid

Abstract

A straw cup lid is provided. The straw cup lid includes a lid and a water stopping member. A pivot hole is disposed on a lid upper surface while a pivot pin is protruding from a bottom of the water stopping member and mounted into the pivot hole to pivotally connect the water stopping member with the lid. A convection hole is located at the lid upper surface and adjacent to the pivot hole and penetrating the lid upper surface while a corresponding protruding block on the bottom of the water stopping member is engaged with the convection hole. The lid upper surface is concave to have a lower central area. A straw slot is on the lid for allowing a top of a straw to protrude therefrom. A water stopping plug on the bottom of the water stopping member is inserted into the straw.

What is claimed is: 
     
         1 . A straw cup lid comprising a lid and a water stopping member;
 wherein the lid includes a lid upper surface, a peripheral wall integrally connected with a periphery of the lid upper surface and extending downward, a pivot hole mounted on the lid upper surface, and a convection hole which is disposed on the lid upper surface, located adjacent to the pivot hole, and penetrating the lid upper surface;   wherein the water stopping member is provided with a pivot pin protruding from a bottom surface thereof and a protruding block arranged at the bottom surface of the water stopping member; the water stopping member is pivotally arranged at the lid by the pivot pin corresponding to and pivotally mounted in the pivot hole; the protruding block is located adjacent to the pivot pin and engaged with the convection hole.   
     
     
         2 . The straw cup lid as claimed in  claim 1 , wherein the lid upper surface is concave downward from the periphery thereof connected with the peripheral wall to form a depression whose central area is lower than surrounding area. 
     
     
         3 . The straw cup lid as claimed in  claim 2 , wherein the lid upper surface is concave in a radial direction of the lid to form a notch on the peripheral wall correspondingly and thus a straw slot is defined by the notch; the straw slot allows a suction port on a top of a straw of a cup to be mounted therein and protrude therefrom; wherein a water stopping plug protrudes from the bottom surface of the water stopping member along an axial direction of the cup and inserted into the suction port on the top of the straw correspondingly. 
     
     
         4 . The straw cup lid as claimed in  claim 3 , wherein a leak-proof protrusion is radially arranged at an outer surface of the water stopping plug. 
     
     
         5 . The straw cup lid as claimed in  claim 4 , wherein an edge at one end of the water stopping member with the water stopping plug is extended outward and tilted to form a flip portion. 
     
     
         6 . The straw cup lid as claimed in  claim 5 , wherein a shield portion is extended downward from a bottom surface of the flip portion and attached to an outer surface of the straw protruding from the straw slot. 
     
     
         7 . The straw cup lid as claimed in  claim 1 , wherein the convection hole on the lid upper surface is located within an area covered by movement of the water stopping member rotated around a central axis of the pivot hole so that the convection hole is shielded by the water stopping member. 
     
     
         8 . The straw cup lid as claimed in  claim 2 , wherein the convection hole on the lid upper surface is located within an area covered by movement of the water stopping member rotated around a central axis of the pivot hole so that the convection hole is shielded by the water stopping member. 
     
     
         9 . The straw cup lid as claimed in  claim 3 , wherein the convection hole on the lid upper surface is located within an area covered by movement of the water stopping member rotated around a central axis of the pivot hole so that the convection hole is shielded by the water stopping member. 
     
     
         10 . The straw cup lid as claimed in  claim 4 , wherein the convection hole on the lid upper surface is located within an area covered by movement of the water stopping member rotated around a central axis of the pivot hole so that the convection hole is shielded by the water stopping member. 
     
     
         11 . The straw cup lid as claimed in  claim 5 , wherein the convection hole on the lid upper surface is located within an area covered by movement of the water stopping member rotated around a central axis of the pivot hole so that the convection hole is shielded by the water stopping member. 
     
     
         12 . The straw cup lid as claimed in  claim 6 , wherein the convection hole on the lid upper surface is located within an area covered by movement of the water stopping member rotated around a central axis of the pivot hole so that the convection hole is shielded by the water stopping member.
