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 combination of a container and a straw that is removably inserted into said container through a straw insert opening in said container, 
 said straw comprising a first tube with a stopping part that bars movement of said first tube farther into said straw insert opening and perforations defining an inlet hole when a part of said tube surrounded by said perforations is removed, said inlet hole being spaced from said stopping part by a distance substantially equal to a thickness of said container.    
   
   
       2 . The combination of  claim 1 , wherein a longitudinal end of said straw that is inserted into said container is a closed end.  
   
   
       3 . The combination of  claim 1 , wherein a longitudinal end of said straw that is inserted into said container is open.  
   
   
       4 . The combination of  claim 1 , further comprising at least one inner tube that is longitudinally movable and rotatable inside said first tube.  
   
   
       5 . The combination of  claim 1 , further comprising a middle tube that is longitudinally movable and rotatable inside said first tube and an inner tube that is longitudinally movable and rotatable inside said middle tube, a wall of said middle tube being selectively movable to a position in alignment with said inlet hole so as to close said inlet hole.  
   
   
       6 . The combination of  claim 1 , wherein said tube comprises a first part that is adjacent to said straw insert opening and that has a constant external diameter, except that at said straw insert opening said first part has a peripheral groove that extends radially inward from said first diameter, said groove being said stopping part and having a size corresponding to said straw insert opening.  
   
   
       7 . A combination of a container and a straw that is removably inserted into said container through a straw insert opening in said container, 
 said straw comprising a first tube with a first part that is adjacent to said straw insert opening and that has a constant external diameter, except that at said straw insert opening said first part has a peripheral groove that extends radially inward from said first diameter, said groove having a size corresponding to said straw insert opening and being arranged to longitudinally hold said straw in said straw insert opening,    said tube further comprising an inlet hole spaced from said groove by a distance substantially equal to a thickness of said container.    
   
   
       8 . The combination of  claim 7 , wherein a longitudinal end of said straw that is inserted into said container is a closed end.  
   
   
       9 . The combination of  claim 7;  wherein a longitudinal end of said straw that is inserted into said container is open.  
   
   
       10 . The combination of  claim 7 , further comprising at least one inner tube that is longitudinally movable and rotatable inside said first tube.  
   
   
       11 . The combination of  claim 7 , further comprising a middle tube that is longitudinally movable and rotatable inside said first tube and an inner tube that is longitudinally movable and rotatable inside said middle tube, a wall of said middle tube being selectively movable to a position in alignment with said inlet hole so as to close said inlet hole.  
   
   
       12 . A combination of a container and a straw that is removably inserted into said container through a straw insert opening in said container, 
 said straw insert opening being covered with a synthetic resin film,    said straw comprising a first tube with a stopping part that bars movement of said first tube farther into said straw insert opening and an inlet hole that is spaced from said stopping part by a distance substantially equal to a thickness of said container, and wherein both longitudinal ends of said straw are open.
