Paper cup cover structure device

Abstract

A paper cup cover structure device is disclosed, which comprises a cup body, being made of a paper, and comprising a cup opening disposed at a top thereof, and a cup bottom disposed at a bottom thereof, the cup opening having a flat cup rim disposed at an outer circumference thereof and having a flat face, the flat cup rim being contained within an extension cirucumferentially disposed downwards; and a cup cover, covering the cup body at the cover top, disposed at an inner wall face corresponding to the cup rim, and having a screw magzine circumferentially disposed with respect thereto, the screw magzine having a push-stop portion extending from a bottom thereof so that the cup rim and the screw magzine are rotationally combined with each other, where the cup body may be further reinforced by using the cup rim having the flat shape.

What is claimed is:  
     
         1 . A paper cup cover structure device, comprising:
 a cup body, being made of a paper, and comprising a cup opening disposed at a top thereof, and a cup bottom disposed at a bottom thereof, the cup opening having a flat cup rim disposed at an outer circumference thereof and having a flat face, the flat cup rim being contained within an extension cirucumferentially disposed downwards; and   a cup cover, covering the cup body at the cover top, disposed at an inner wall face corresponding to the cup rim, and having a screw magzine circumferentially disposed with respect thereto, the screw magzine having a push-stop portion extending from a bottom thereof so that the cup rim and the screw magzine are rotationally combined with each other.   
     
     
         2 . The paper cup cover structure device as claimed in  claim 1 , wherein the cup rim and the extension portion are formed by folding up a pressed fit curling formed circumferentially at the cup opening. 
     
     
         3 . The paper cup cover structure device as claimed in  claim 1 , wherein the cup rim is made of plastic or paper and formed by frame molding or paper molding. 
     
     
         4 . The paper cup cover structure device as claimed in  claim 1 , wherein the push-stop portion takes an inverse-hook shape running slightly outwards 
     
     
         5 . The paper cup cover structure device as claimed in  claim 1 , wherein the push-stop portion is inclined and runs outwards. 
     
     
         6 . The paper cup cover structure device as claimed in  claim 1 , wherein the push-stop portion has a protruding rib circumferentially disposed at an inner side thereof so as to stop against a lower rim of the cup rim. 
     
     
         7 . The paper cup cover structure device as claimed in  claim 1 , wherein the push-stop portion has a plurality of ribs spacedly and circumferentially arranged at the inner side so as to stop against a lower rim of the cup rim.
