Straw

Abstract

A straw ( 3 ) capable of being detachably inserted into the straw insert hole ( 2 ) of a press-deformable container ( 1 ) having the straw insert hole ( 2 ), characterized by comprising a locking part ( 4 ) for stopping the insertion of the straw ( 3 ) into the straw insert hole ( 2 ) and a through hole ( 5 ) positioned apart from the locking part ( 4 ) by a distance (W) almost the same as the thickness of a container forming material having the straw insert hole ( 2 ).

1 . A straw  3  adapted to be removably inserted into a press deformable container  1  through a straw insert opening  2  of the container  1 , which is characterized by having a stopping part  4  for stopping itself from being inserted through the straw insert opening  2  and an inlet hole  5  at a position distant from the position of the stopping part  4  by a distance substantially equal to the thickness W of the container-forming material having the straw insert opening  2 .  
     
     
         2 . The straw according to  claim 1 , characterized by having tear-out perforations at a position distant from the stopping part  4  by said distance, the part surrounded by the tear-out perforations being adapted to be torn out to make the inlet hole  5 .  
     
     
         3 . The straw according to  claim 1 , characterized in that the longitudinal end thereof which is adapted to be inserted into the container  1  is a closed end  7 .  
     
     
         4 . The straw according to  claim 1 , characterized by having at least one inner tube  8  fitted therein rotatably and longitudinally slidably, the inner tube  8  being adapted to be slid or rotated to open and close the inlet hole  5 .  
     
     
         5 . The straw according to  claim 4 , characterized in that the inner tube  8  has an inner hole  9  at a position distant from the position of the stopping part  4  by said distance and is adapted to be rotated to interconnect the inner hole  9  and the inlet hole  5 .  
     
     
         6 . The straw according to  claim 1 , wherein the stopping part  4  is a snap fit part, a groove fit part, a stop collar, a shoulder or a protrusion  
     
     
         7 . The straw according to  claim 1 , wherein a part of or the whole of the section between the stopping part  4  and the pour outlet  32  is bellows  10 .  
     
     
         8 . A straw  3  adapted to be removably inserted into a press-deformable container  1  through a straw insert opening  2  of the container  1 , which is characterized by comprising an outer tube  3   a , a middle tube  3   b , and an inner tube  3   c , the middle tube  3   b  and the inner tube  3   c  being fitted into the outer tube  3   a  longitudinally slidably, the outer tube  3   a  having a stopping part  4  for stopping itself from being inserted through the straw insert opening  2  and an inlet hole  5  at a position distant from the position of the stopping part  4  by a distance substantially equal to the thickness W of the container-forming material having the straw insert opening  2 , and the inlet hole  5  being opened and closed by sliding at least the middle tube  3   b.    
     
     
         9 . The straw according to  claim 8 , wherein the stopping part  4  is a snap fit part, a groove fit part, a stop collar, a shoulder or a protrusion  10 . The straw according to  claim 8 , wherein a part of or the whole of the section between the stopping part  4  and the pour outlet  32  is bellows  10 .
