Abstract

A folding storage device includes a storage box, a vacuum storage bag and a bottom plate. The storage box includes a box body made of soft sheets and frames disposed inside the sides of the box body. The box body can be folded and expanded. The vacuum storage bag has an air valve. After articles are placed into the vacuum storage bag, the vacuum storage bag can be compressed through the air valve and then placed into the storage box. The bottom plate can be twisted and folded and is placed at the bottom of the vacuum storage bag to increase the space of the vacuum bag for the articles to be placed into the bag with ease.
