Gas substitution device

Abstract

The present invention has been made in an effort to more assuredly substitute oxygen in a vial. A gas substitution apparatus according to the exemplary embodiment of the present invention includes: a first gas substitution unit which seals a periphery of an opening of a vial disposed in a gas substitution section, and guides a flow of a first substitution gas to be supplied into the vial; and a second gas substitution unit which is coupled to an upper side of the first gas substitution unit, and guides a flow of a second substitution gas to be supplied directly into the vial.

1 . A gas substitution apparatus comprising:
 a first gas substitution unit which seals a periphery of an opening of a vial disposed in a gas substitution section, and guides a flow of a first substitution gas to be supplied into the vial; and   a second gas substitution unit which is coupled to an upper side of the first gas substitution unit, and guides a flow of a second substitution gas to be supplied directly into the vial.   
     
     
         2 . The gas substitution apparatus of  claim 1 , wherein
 the first gas substitution unit includes a plurality of gas tunnel portions which extend in the gas substitution section in a direction in which the vial is conveyed, and   the plurality of gas tunnel portions include:   a first gas tunnel portion which is installed in a straight section in the gas substitution section; and   a second gas tunnel portion which is connected to one end of the first gas tunnel portion.   
     
     
         3 . The gas substitution apparatus of  claim 2 , wherein
 the first gas tunnel portion includes:   a first tunnel body which is opened at a lower side thereof and formed straight; and   a first tunnel connecting portion which is coupled to one side of the first tunnel body.   
     
     
         4 . The gas substitution apparatus of  claim 3 , wherein
 the second gas tunnel portion includes:   a second tunnel body which is opened at a lower side and a part of a lateral side thereof, and has a curved shape; and   a second tunnel connecting portion which is coupled to an upper side of the second tunnel body.   
     
     
         5 . The gas substitution apparatus of  claim 4 , wherein
 the second tunnel body of the second gas tunnel portion is installed in a curved section of the gas substitution section.   
     
     
         6 . The gas substitution apparatus of  claim 2 , wherein
 the first gas tunnel portion and the second gas tunnel portion are integrally formed.   
     
     
         7 . The gas substitution apparatus of  claim 1 , wherein
 the gas substitution section is set from a section in which the vial is filled with contents to a section in which the opening of the vial is covered.   
     
     
         8 . The gas substitution apparatus of  claim 1 , wherein
 the second gas substitution unit includes:   a body portion which has a hermetic internal space, and is coupled to the first tunnel body;   an auxiliary connecting portion which is coupled to one side of the body portion; and   a nozzle unit which is disposed in the first tunnel body, and has an inlet which is coupled to a lower side of the body portion, and a length such that an outlet of the nozzle unit is adjacent to the opening of the vial.   
     
     
         9 . The gas substitution apparatus of  claim 8 , wherein
 a nozzle inner diameter of the nozzle unit is 3.5 mm to 25 mm.
