Spout and liquid container with spout

Abstract

A spout ( 4 ) that is attached to a pouch-like bag and through which the contents filled in the bag are discharged, the spout includes: a tubular portion ( 49 ) in which a through hole ( 12 ) is formed and from a leading end of which the contents are discharged; and a rib ( 20 ) that extends from the inner circumferential surface of the tubular portion ( 9 ) towards the central axis side ( 13 ) of the through hole ( 12 ). A hole ( 21 ) surrounded by the edge of the extended rib ( 20 ) is formed in the part where the rib ( 20 ) is formed. This configuration makes it easy to secure the strength of the rib ( 20 ) and is advantageous in preventing breakage and deformation of the rib ( 20 ). Thus, accidental insertion of connecting needles can be prevented with more certainty.

1 . A spout that can be attached to a liquid container and through which contents filled in the liquid container are discharged, the spout comprising:
 a tubular portion in which a through hole is formed and from a leading end of which the contents are discharged; and   a rib that extends from an inner circumferential surface of the tubular portion towards a central axis side of the through hole,   wherein a hole surrounded by an edge of the rib is formed in a part where the rib is formed.   
     
     
         2 . The spout according to  claim 1 , wherein an inclined surface that inclines in the leading end side of the tubular portion towards the central axis of the through hole is formed on the rib on the leading end side of the tubular portion. 
     
     
         3 . The spout according to  claim 1 , wherein an inclined surface that inclines in the leading end side of the tubular portion towards the central axis of the through hole is formed on the rib on a base end side of the tubular portion. 
     
     
         4 . The spout according to  claim 1 , wherein inclined surfaces that incline in the leading end side of the tubular portion towards the central axis of the through hole are formed on the rib on the leading end side and a base end side of the tubular portion, respectively. 
     
     
         5 . The spout according to  claim 1 , further comprising a base that is attached to the liquid container,
 wherein the tubular portion protrudes from the base, and a protruding dimension of the tubular portion from the base is 1 mm or more and 10 mm or less.   
     
     
         6 . The spout according to  claim 1 , further comprising an air-permeable filter. 
     
     
         7 . The spout according to  claim 1 , wherein the liquid container is a pouch-like bag or a bottle. 
     
     
         8 . A liquid container with a spout comprising the spout according to  claim 1 . 
     
     
         9 . The liquid container according to  claim 8 , further comprising a liquid stopper cap for sealing the spout,
 wherein when the liquid stopper cap is attached to the spout, the minimum distance between a leading end of the liquid stopper cap and the rib is 5 mm or less.
