Cup and blank for forming

Abstract

A blank ( 10 ) for forming a cup comprises opposing first and second surfaces ( 12, 14 ); opposing first and second side edges ( 16, 20 ); opposing top and bottom edges ( 24, 26 ); a rim portion ( 28 ) extending across the top edge; and an edge tape ( 30 ) extending along the first side edge ( 16 ) from the bottom edge ( 26 ) toward the top edge ( 24 ), with the edge tape ( 30 ) folded over such that the edge tape extends along the first surface ( 12 ) and second surface ( 14 ). The first side edge ( 16 ) extends such that the edge tape ( 30 ) folds over onto itself in at least part of the rim portion.

1 . A blank for forming a cup, the blank comprising:
 opposing first and second surfaces;   opposing first and second side edges;   opposing top and bottom edges;   a rim portion extending across the top edge; and   an edge tape extending along the first side edge from the bottom edge toward the top edge, the edge tape folded over such that the edge tape extends along the first surface and second surface;   wherein the first side edge extends such that the edge tape folds over onto itself in at least part of the rim portion;   wherein the first side edge extends in a straight line from the bottom edge to the start of the rim portion and then extends at an angle from the straight line portion; and   wherein the edge tape extends to the top edge or ends at about 50% of the height of the rim portion.   
     
     
         2 .- 5 . (canceled) 
     
     
         6 . The blank of  claim 1 , wherein at least one of the first and second surfaces comprises a coating. 
     
     
         7 . The blank of  claim 1 , wherein the second side edge extends with a straight line from the bottom edge to the start of the rim portion and then extends at an angle from the straight line portion. 
     
     
         8 . The blank of  claim 1 , wherein the edge tape is a polymer and/or laminate structure. 
     
     
         9 . A cup formed with the blank of  claim 1 ,
 wherein the blank is rolled into a circular or conical sleeve such that the first and second side edges overlap with the first side edge with edge tape in an inside position;   wherein the blank is sealed along at least part of the overlapping portion;   wherein the rim portion is rolled or folded over to form a cup rim; and   further comprising a bottom portion connected at a base of the sleeve.   
     
     
         10 . The cup of  claim 9 , wherein the edge tape folded over onto itself forms a part of an upper portion of the cup rim. 
     
     
         11 . The cup of  claim 10 , and further comprising a lid heat-sealed to the rim. 
     
     
         12 . A method comprising:
 obtaining a cup according to  claim 9 ; and   heat-sealing a lid to the rim of the cup.   
     
     
         13 . The method of  claim 12 , and further comprising filling the cup with a food or drink prior to the step of heat-sealing. 
     
     
         14 . A method of producing a blank, the method comprising:
 obtaining a blank with opposing first and second surfaces, opposing first and second side edges, opposing top and bottom edges, and a rim portion extending across the top edge, wherein the first side edge extends in a straight line from the bottom edge to the start of the rim portion and then extends at an angle from the straight line portion;   applying an edge tape along the first side edge such that the edge tape folds over onto the first and second surfaces from the bottom edge toward the top edge; wherein the edge tape folds over onto itself in at least a part of the rim portion, and wherein the edge tape extends to the top edge or wherein the edge tape ends at about 50% of the height of the rim portion.   
     
     
         15 . The method of  claim 14 , and further comprising:
 forming angled corners along the first and/or second side edges at the rim portion.
