Bag with means for vacuuming an internal space thereof

A bag with means for vacuuming an internal space thereof, said bag comprising:

• an air impermeable bag body confining said internal space for receiving things therein and having an opening formed therethrough for communicating an exterior of said bag body and said internal space;
• a fixing seat which is secured to said bag body and which covers a periphery of said opening, said fixing seat having a through-hole formed therethrough and communicated with said internal space;
• a check valve made of flexible material and comprising a first portion substantially fixedly mounted on said fixing seat, said check valve including a covering unit, said covering unit comprising a second portion of said check valve movably mounted with respect to said first portion of said check valve, wherein said covering unit is movable between a first position that covers hermetically said through-hole of said fixing seat when pressure within said internal space is lower than that at the exterior of said bag body, thereby preventing air from entering into said internal space via said through-hole, and a second position wherein said through-hole is uncovered for permitting air within said internal space to be released through the exterior of said bag body through said through-hole;
• and
• a bowl-shaped cover member enclosing hermetically said check valve and having a flat plate which is spaced and parallel to said covering unit so as to define a space between said flat plate and said covering unit, said flat plate having at least one passage hole formed therethrough.
