Inflatable protective bag

Abstract

An inflatable protective bag includes a housing sack, a gasbag, an inflation means, a check valve and a deflation valve. The gasbag is attached to an inner surface of the housing sack. The inflation means communicates with the gasbag through the check valve. The deflation valve is located on the gasbag. When the housing sack contains goods, air can be injected into the gasbag by the inflation means through the check valve to inflate the gasbag to provide resilient protection for the goods from being damaged. The air can be released from the gasbag by pushing the deflation valve to facilitate removing of the goods. Thus the inflatable protective bag can provide protection as desired.

1 . An inflatable protective bag, comprising:
 a housing sack having a housing space;   a gasbag located on the surface of the housing space;   an inflation means communicating with the gasbag and generating air injected into the gasbag,   a check valve interposed between the inflation means and the gasbag to allow the air entering the gasbag one way; and   a deflation valve located on the gasbag to release the air from the gasbag.   
     
     
         2 . The inflatable protective bag of  claim 1 , wherein the inflation means is located on the surface of the housing sack communicating with the gasbag through an air duct. 
     
     
         3 . The inflatable protective bag of  claim 2 , wherein the check valve is located between the inflation means and the air duct. 
     
     
         4 . The inflatable protective bag of  claim 3 , wherein the deflation valve has an air release button, a channel and an elastic element; the channel communicating with the air duct and extending to the surface of the housing sack, the air release button being held in the channel and jutting outside the surface of the housing sack upon elastically pushed by the elastic element to close the channel, the channel being opened when the elastic element is compressed by the air release button. 
     
     
         5 . The inflatable protective bag of  claim 3 , wherein the check valve has two membranes bonding together to form a passage therebetween to communicate with the inflation means and the air duct, the two membranes having at least one contact surface coated with a release layer at one end of the passage close to the inflation means. 
     
     
         6 . The inflatable protective bag of  claim 1 , wherein the check valve has two membranes bonding together to form a passage therebetween to communicate with the inflation means and the air duct, the two membranes having at least one contact surface coated with a release layer at one end of the passage close to the inflation means. 
     
     
         7 . The inflatable protective bag of  claim 1 , wherein the inflation means is an elastic gasbag having an opening. 
     
     
         8 . The inflatable protective bag of  claim 1 , wherein the inflation means is an elastic gasbag having a one-way valve. 
     
     
         9 . The inflatable protective bag of  claim 8 , wherein the one-way valve has a holding seat, an air stopper and a stopper seat; the holding seat having a sliding chamber which has an air vent at one end communicating with the inflation means and the other end communicating to exterior; the air stopper being retained by the stopper seat which being coupled to the holding seat and slidable in the sliding chamber to close the air vent. 
     
     
         10 . The inflatable protective bag of  claim 1 , wherein the inflation means is a bag filled with a pliable, elastic and porous material.
