Vacuum stabilized carry bag

Abstract

A carry bag ( 60 ) has flexible walls ( 69 ) defining an enclosure adapted to house contents of the bag. The enclosure has an opening ( 64 ) for receiving the contents therethrough, the opening being sealable for airtightness of the enclosure. There are also means, including a pump ( 68 ), for evacuating air from the enclosure so as to compress the walls against the contents to thereby restrain the contents from movement.

1 . A carry bag comprising flexible walls defining an enclosure adapted to house contents of the bag, the enclosure having an opening for receiving the contents therethrough, the opening being sealable for airtightness of the enclosure, and means for evacuating air from the enclosure so as to compress the walls against the contents to thereby restrain the contents from movement. 
   
   
       2 . The carry bag of  claim 1  wherein the enclosure is an inner bag of the carry bag. 
   
   
       3 . The carry bag of  claim 1  wherein the air evacuating means is a suction pump. 
   
   
       4 . The carry bag of  claim 1  wherein the walls of the inner bag and its contents are compressed against a rigid support wall of the carry bag. 
   
   
       5 . The carry bag of  claim 1  wherein the carry bag is a backpack having a rigid support wall adapted to abut against the back of a user, and including an inner bag having flexible walls and a sealable opening that allows contents to be packed and sealed within the inner bag and for a vacuum to be created and maintained when the opening is sealed. 
   
   
       6 . The carry bag of  claim 5  wherein the inner bag is coupled to an air pump that, in use, evacuates air from the inner bag so as to cause the contents to be tightly secured against the rigid support wall, thereby reducing the volume of space occupied by the carry bag.
