pump located directly above the aperture 21 in the storage container 20 40 the apertures are formed in a lower stiff layer 50 although the bellows vacuum pump works fine with a single aperture 52 it is preferred to have multiple smaller apertures 52 to reduce the possibility of the contents 24 44 from entering the pump mechanism for example if the container is filled with coffee beans multiple smaller apertures 52 will reduce the amount of particulate coffee beans that are sucked into the bellows portion 80 and possibly blown out of the exit aperture 76 in addition distributed apertures 52 reduce the chances of all apertures 52 being blocked due to a collapsed container 20 in some embodiments where the container is a plastic bag film bag the inner surface of the plastic bag has grooves or channels to further reduce the possibility of a collapsed bag blocking the inlet apertures 52 each aperture 52 is covered by a flexible hinged valve 62 formed on a flexible layer 60 the flexible hinged valves 62 lift when air flows out of the storage container 20 40 and lay flat thereby sealing their respective aperture 52 when air flows out of the bellows portion 80 the air flowing 82 from the storage container 20 40 flows through another aperture 72 in an upper stiff layer 70 and into the bellows portion 80 when pressure is applied to the bellows portion 80 air 84 flows out.
