Cup for holding a beverage and blank for forming a sidewall with integrated flaps of a cup

Abstract

The present disclosure is directed to a cup including a base, a sidewall having a lower end portion connected to the base so that the base and the sidewall together define a space, and at least four flaps that are connected to an upper end portion of the sidewall via respective folding lines. The flaps are foldable relative to the sidewall between an open position, in which the flaps are oriented in parallel to the sidewall, and a closed position, in which the flaps are folded inwards so to form a lid of the cup. The at least four flaps include a first and a second flap having a first width, and a third and a fourth flap having a second width, wherein in the closed position, the at least four flaps define at least two faces of the lid, and wherein the third flap includes a drinking opening.

What is claimed is: 
     
         1 . A cup for holding a beverage, comprising:
 a base;   a sidewall having a lower end portion connected to the base so that the base and the sidewall together define a space configured for receiving the beverage; and   at least four flaps that are connected to an upper end portion of the sidewall via respective folding lines, the flaps being foldable relative to the sidewall between an open position, in which the flaps are oriented in parallel to the sidewall, and a closed position, in which the flaps are folded inwards so to form a lid of the cup;   wherein the at least four flaps include a first and a second flap each having a first width, the first width being an extension in the peripheral direction of the cup, and a third and a fourth flap each having a second width, wherein the first width is larger than the second width,   wherein, in the closed position, the at least four flaps define at least two faces of the lid, and in that the third flap includes a drinking opening.   
     
     
         2 . The cup according to  claim 1 , wherein each of the at least four flaps is not directly connected to any other of the at least four flaps. 
     
     
         3 . The cup according to  claim 1 , wherein the first flap and second flap in the closed position define a first face having a concave surface. 
     
     
         4 . The cup according to  claim 3 , wherein the third flap in the closed position defines a second face having a concave surface or in that the fourth flap in the closed position defines a third face having a concave surface. 
     
     
         5 . The cup according to  claim 1 , wherein the folding lines are curved such that in the open position, a shortest distance from the respective folding line to the bottom is arranged at a middle position along the corresponding width of the corresponding flap. 
     
     
         6 . The cup according to  claim 5 , wherein the third flap and the fourth flap each include a further folding line, wherein the respective further folding line is curved such that, in the open position, a longest distance from the respective further folding line to the bottom is arranged at a middle position along the width of the flap. 
     
     
         7 . The cup according to  claim 6 , wherein the further folding line of the third flap intersects the folding line of the third flap at both edges delimiting the flap in the peripheral direction. 
     
     
         8 . The cup according to  claim 1 , wherein the drinking opening is configured as a straw hole or a sip hole. 
     
     
         9 . The cup according to  claim 1 , wherein the drinking opening is delimited by the folding line of the third flap. 
     
     
         10 . The cup according to  claim 1 , wherein the drinking opening is covered by a drinking opening flap connected to the upper end portion of the sidewall via the folding line of the third flap. 
     
     
         11 . The cup according to  claim 1 , wherein the drinking opening flap is removable. 
     
     
         12 . The cup according to  claim 1 , wherein the first flap further comprises a tab that can be locked with the second flap in the closed position. 
     
     
         13 . The cup according to  claim 1 , wherein the bottom and the sidewall and the at least four flaps are made from paper. 
     
     
         14 . A blank for forming a sidewall with integrated flaps of a cup, the blank comprising:
 a sidewall; and   at least four flaps that are connected to an upper end portion of the sidewall via respective folding lines, the flaps being individually foldable relative to the sidewall;   wherein the at least four flaps include a first and a second flap having a first width, the first width being an extension in the peripheral direction of the cup, and a third and a fourth flap having a second width, wherein the first width is larger than the second width,   wherein the third flap includes a drinking opening.   
     
     
         15 . The blank according to  claim 14 , wherein each of the at least four flaps is not directly connected to any other of the at least four flaps.
