Paper cup

Abstract

The disposable paper cup has a body formed of a cylindrical wall with a recess at the top. The portions of the body wall adjacent either side of the recess are aligned into a flap. The flap is folded over and secured to the exterior surface of the body wall to entirely enclose the cup body, except for an integral spout formed by the recess.

I claim: 
     
         1 . A disposable paper cup comprising an entirely enclosed body except for an integral spout. 
     
     
         2 . A disposable paper cup comprising a body formed of a generally cylindrical wall with a top portion having a recess, wherein the portions of said wall adjacent said recess are folded over to entirely enclose the body, other than a spout formed by said recess. 
     
     
         3 . The cup of  claim 2  wherein said wall portions are aligned and moved into side-by-side relation prior to being folded. 
     
     
         4 . The cup of  claim 3  wherein said folded portions are sealed to said body after being folded. 
     
     
         5 . The cup of  claim 2  wherein said folded portions are secured to said body. 
     
     
         6 . The cup of  claim 2  further comprising an insulating sleeve. 
     
     
         7 . A method of forming a disposable paper cup body from a generally rectangular paper sheet part having a top edge and opposite sides, the method comprising the steps of:
 (a) creating a recess in the sheet part adjacent the top edge;   (b) sealing the sides of the sheet part to form a generally cylindrical body;   (c) aligning the portions of the body on either side of the recess;   (d) moving the aligned portions of the body together into side-by-side relation; and   (e) folding the aligned portions to a position adjacent the exterior of the cup body such that the recess forms a spout.   
     
     
         8 . The method of  claim 7  further comprising the step of:
 (f) securing the aligned portions to the exterior of the cup body. 
 
     
     
         9 . The method of  claim 7  further comprising the steps of:
 (g) creating a generally cylindrical sleeve of heat insulating material; and 
 (h) inserting the cup body into the sleeve. 
 
     
     
         10 . The method of  claim 7  further comprising forming a bottom for the cup body and sealing the bottom to the cup body. 
     
     
         11 . The method of  claim 9  wherein said method results in a cup body which is entirely enclosed, except for an integral spout. 
     
     
         12 . The method of  claim 7  further comprising the steps of:
 (i) creating a sleeve; and 
 (j) inserting the cup body in the sleeve.
