Abstract (en)
[origin: US2004057636A1] A compactor bag which has a substantially rectangular bag body 11 made of synthetic resin films 12 and 13, the bag body having an openable side 14 provided with a zipper 15 through which an item can be put into and taken out of the bag body 11. Check valve portions 20 are provided in right-triangular areas at both corners of a side opposite the openable side 14. Each of the check valve portions 20 has a flat and closable air release path 22 which is formed by fused portions f, g and 21 of the films 12 and 13, and air inside the bag body 11 is guided into the air release path 22 by the hypotenuse of the right-triangular area and is exhausted from the bag body 11 as indicated by arrow "d". The check valve portions 20 communicate with a packing space of the bag body 11 at the respective hypotenuses of the right-triangular areas. The check valve portions may be made of thin and soft films inserted between the films 12 and 13.
