Abstract

The present invention is to provide a vacuum hanger bag having a bag with an airtight closure, a one-way valve installed to the bag, and a hook disposed on the top end of the bag. The hook secured to an outer side of the bag, it consists of a hook with a jut projected downward from its bottom end to penetrate into an inner side of the bag. A base secured to the inner side of the bag with an axial hole for said jut embedding into. An impervious stopper is hidden from view retained at a bottom end of the axial hole. A nut is threaded to a bottom end of the base. And a hook ring with a jut projected upward from its top end is embedded into the nut.
