1. A degasifier for removing gas from a packing bag, the degasifier comprising:
a degassing chamber which is openable and closable and is closed in a state where a lid of the degasifier is mounted on a body of the degasifier; and
a pair of gaskets, wherein a first gasket of the pair of gaskets is provided in the body and a second gasket of the pair of gaskets is provided in the lid, and wherein the first gasket and the second gasket are in pressure-contact with each other around the degassing chamber when the degassing chamber is closed,
wherein the packing bag is sandwiched between the pair of gaskets such that a bag opening of the packing bag is arranged inside the closed degassing chamber to degas the packing bag by decompressing the inside of the closed degassing chamber,
wherein the first gasket and the second gasket include a first sandwiching surface and a second sandwiching surface, respectively, for sandwiching the packing bag,
wherein the degasifier further comprises:
a pair or pairs of suction openings including a first suction opening disposed on the first sandwiching surface of the first gasket of the body and a second suction opening disposed on the second sandwiching surface of the second gasket of the lid without the first suction opening and the second suction opening opening directly into the degassing chamber, wherein the first suction opening and the second suction opening are disposed to mutually oppose each other while sandwiching the packing bag; and
a decompressor that decompresses inside the suction openings, and
wherein the pair or pairs of suction openings creates, inside the packing bag, an airway that communicates the inside and outside of the degassing chamber by decompressing the inside of each of the suction openings using the decompressor and creating suction against the packing bag using the suction openings while the bag opening of the packing bag having a smooth surface is arranged in the closed degassing chamber and sandwiched between the first sandwiching surface of the first gasket on which the first suction opening is disposed and the second sandwiching surface of the second gasket on which the second suction opening is disposed.
