Deaerator-carrying compression bag

Abstract

A deaerator-carrying compression bag ( 1 ) capable of deaerating even when a deaerating pump nozzle is not inserted deep into a bag body, comprising a resin bag body ( 10 ) formed at one edge of the outer peripheral edge ( 1 ) thereof with an opening ( 11 A) for storing an article to be stored ( 16 ), a fastener ( 12 ) provided on the inner surface of the bag body ( 10 ) and acting as an occluding tool for blocking the opening ( 11 A), and a resin deaerator ( 13 ) for exhausting the air inside the bag body ( 10 ), wherein the deaerator ( 13 ) is welded to the bag body ( 10 ) at the base end ( 13 A) of the deaerator ( 13 ), and the deaerator ( 13 ) has a back-flow preventing means ( 15 ) for preventing the back-flow of air into the bag body ( 10 ).

1 . A deaerator-carrying compression bag, comprising: a resin-made bag body having an opening for an article to be put in at a side of an outer peripheral edge thereof; a snap fastener provided on inner surface of the bag body for closing the opening; and a resin-made deaerator for discharging air inside the bag body, 
 wherein the deaerator and the bag body are welded at a base end of the deaerator, and    wherein the deaerator has a back-flow preventing means for preventing the air from back-flowing into an inside of the bag body.    
     
     
         2 . The deaerator-carrying compression bag according to  claim 1 , 
 wherein the deaerator is located approximately at the center of the bag body.    
     
     
         3 . The deaerator-carrying compression bag according to  claim 1  or  2 , 
 wherein the back-flow preventing means includes a check-valve structure.  
 
     
     
         4 . The deaerator-carrying compression bag according to any one of  claims 1  to  3 , 
 wherein a fining member having a male and a female member which are fitted to seal the inside of the bag body is provided to the back-flow preventing means.
