Abstract

The invention refers to a paper drinking straw (1) for a beverage container (81,83) with a penetration opening (80,84) for inserting the paper drinking straw, wherein the paper drinking straw comprises a paper tube (2) with a bevelled tip (7) at a first end (3), wherein paper of paper tube is more compressed at the first end compared to other portions of the paper tube.

1 . A paper drinking straw for a beverage container with a penetration opening for inserting the paper drinking straw, wherein the paper drinking straw comprises a paper tube with a bevelled tip at a first end,
 characterised in that   a paper of the paper tube is more compressed at the first end compared to other portions of the paper tube.   
     
     
         2 . The paper drinking straw according to  claim 1 , wherein the paper tube comprises a second end opposite to the first end and the paper is more compressed at the first end compared to the second end. 
     
     
         3 . The paper drinking straw according to  claim 1 , wherein the paper of the paper tube is compressed to a reduced wall thickness at the first end compared to the other portions of the paper tube. 
     
     
         4 . The paper drinking straw according to  claim 1 , wherein the paper of the paper tube is compressed at the first end in only a section of the circumference of the paper tube wherein optionally the transition in the circumferential direction from the compressed paper in the section to the uncompressed paper outside of the section is a continuous transition. 
     
     
         5 . The paper drinking straw according to  claim 1 , wherein the entire circumference of the paper tube is compressed. 
     
     
         6 . The paper drinking straw according to  claim 1 , wherein, along the length of the paper tube starting at the first end the compressed paper is provided only in a range up to 5%, 10% or 20% of the length of the paper tube. 
     
     
         7 . The paper drinking straw according to  claim 1 , wherein the density of the compressed paper is at least 1.2, 1.5, 2.0, or 3.0 times higher than in the other portions of the paper tube. 
     
     
         8 . The paper drinking straw according to  claim 1 , wherein the thickness of the compressed paper is less than 0.9, 0.8, 0.7, 0.6 or 0.5 times the thickness of the other portions of the paper tube wherein the thickness of the other portions is the thickness at the thickest portion of the paper tube. 
     
     
         9 . The paper drinking straw according to  claim 1 , wherein a portion of the compressed paper or all of the compressed paper is impregnated with moisture resistant agent, wherein the moisture resistant agent is silicate or sodium silicate. 
     
     
         10 . The paper drinking straw according to  claim 1 , wherein the paper drinking straw has a circular cross section along the entire length of the paper tube or at least in the region where the compressed paper is present and/or in the other portions. 
     
     
         11 . The paper drinking straw according to  claim 1 , wherein the paper tube comprises a winded paper layer. 
     
     
         12 . The paper drinking straw of  claim 1 , wherein the paper tube comprises a single paper layer or several layers of paper. 
     
     
         13 . A beverage container for receiving liquid product, wherein the beverage container comprises a penetration opening for introducing the paper drinking straw of  claim 1 . 
     
     
         14 . The beverage container of  claim 13 , wherein the beverage container is designed as a beverage carton, a foil bag or a stand-up pouch made of foil.
