Vacuum-packing container using a packing stand

Abstract

A vacuum-packing container using a packing bag, which includes a packing bag that contains an article therein, and a casing that receives the packing bag therein, with a nozzle valve connected to the packing bag so as to form an air passage, and so air can be drawn out of the packing bag through the nozzle valve, thereby realizing vacuum-packing of the article in the packing bag. The packing bag is removably installed in the casing, and the article in the packing bag can be quickly and efficiently compressed to a high level of vacuum using a vacuum cleaner. Further, the packing bag can be changed with a new one at any time, and the article can be safely stored, and a large number of vacuum-packing containers can be efficiently stored due to the casings that can be neatly stacked one by one.

1 . A vacuum-packing container using a packing bag, comprising:
 a packing bag ( 500 ) for storing articles therein, a casing ( 100 ) for receiving the packing bag ( 500 ) therein, and a nozzle valve (V) provided in a wall of the casing ( 100 ) such that the nozzle valve can be connected to the packing bag ( 500 ) so as to allow air to flow through the nozzle valve, wherein air is drawn out of the packing bag ( 500 ) through the nozzle valve (V), thereby vacuum-packing the articles in the packing bag ( 500 ).   
     
     
         2 . The vacuum-packing container using the packing bag as set forth in  claim 1 , wherein the nozzle valve (V) is configured such that the nozzle valve prevents air from flowing reversely into the packing bag ( 500 ). 
     
     
         3 . The vacuum-packing container using the packing bag as set forth in  claim 2 , wherein the nozzle valve (V) includes: an inner coupler ( 200 ) that is mounted by passing through the packing bag ( 500 ) and through the wall of the casing ( 100 ) from an inside of the packing bag ( 500 ), and functions to be connected to a suction nozzle ( 600 ) of a vacuum cleaner. 
     
     
         4 . The vacuum-packing container using the packing bag as set forth in  claim 3 , wherein the inner coupler ( 200 ) includes: a locking part ( 210 ) that is provided with a discharge hole ( 202 ) for discharging air and is mounted to an outer coupler ( 300 ) by a screw type fitting method; a nozzle connection part ( 220 ) that is formed around an inner circumferential surface of the locking part ( 210 ) and is connected to the suction nozzle ( 600 ) of the vacuum cleaner; a stop flange ( 230 ) that is formed by extending outward in radial directions from an inside end of the locking part ( 210 ) and closely mounts the packing bag ( 500 ) to an inner surface of the wall of the casing ( 100 ); and a check plate ( 240 ) that is received in the stop flange ( 230 ) and has a plate shape, and is provided with a check valve ( 242 ) in a central portion thereof so as to control air to flow in exclusively one direction. 
     
     
         5 . The vacuum-packing container using the packing bag as set forth in  claim 4 , wherein the stop flange ( 230 ) is provided with a close contact surface ( 232 ) on a front surface thereof, with a plurality of annular ribs formed in the close contact surface ( 232 ) so as to prevent the packing bag ( 500 ) from being removed from between the casing ( 100 ) and the close contact surface ( 232 ). 
     
     
         6 . The vacuum-packing container using the packing bag as set forth in  claim 4 , wherein the check valve ( 242 ) is biased by an elastic restoring force. 
     
     
         7 . The vacuum-packing container using the packing bag as set forth in  claim 4 , wherein the check valve ( 242 ) is provided with an inclined surface ( 244 ) around an outer circumferential surface of the check valve in such a way that a diameter of an outside edge of the check valve in a direction toward the inner surface of the casing ( 100 ) is larger than a diameter of an inside edge of the check valve, and the check plate ( 240 ) is provided with an inclined seat surface ( 246 ) for seating the inclined surface ( 244 ) thereon, and so the check valve ( 242 ) can be prevented from moving to an exhaust hole ( 252 ) of a check plate holder ( 250 ) due to a negative pressure acting in the packing bag ( 500 ). 
     
     
         8 . (canceled) 
     
     
         9 . The vacuum-packing container using the packing bag as set forth in  claim 3 , wherein the inner coupler ( 200 ) includes: a locking part ( 210 ) that is provided with a discharge hole ( 202 ) for discharging air and is mounted to an outer coupler ( 300 ) by a screw type fitting method; a nozzle connection part ( 220 ) that is formed in an end of the locking part ( 210 ) and is connected to the suction nozzle ( 600 ) of the vacuum cleaner; a stop flange ( 230 ) that is formed by extending outward in radial directions from an inside end of the locking part ( 210 ) and closely mounts the packing bag ( 500 ) to an inner surface of the wall of the casing ( 100 ); and a sealing plug ( 280 ) that is received in the nozzle connection part ( 220 ) and closes the discharge hole ( 202 ), wherein the sealing plug ( 280 ) is provided with an actuation rod ( 282 ) having an axial slit ( 283 ), the actuation rod ( 280 ) being installed by passing through the discharge hole ( 202 ) and by being tightened with a locking nut ( 284 ) at a location inside the packing bag such that the actuation rod can be prevented from being removed from the discharge hole ( 202 ), with a spring ( 286 ) being placed to bias the actuation rod, such that, when the suction nozzle ( 600 ) is operated to draw air, the actuation rod is pulled so as to open the discharge hole ( 202 ), and when an operation of the suction nozzle is stopped, the actuation rod is returned to an original position thereof, thereby closing the discharge hole ( 202 ).
