Abstract: A flat bag storing a liquid-impregnated sheet-shaped object has on its top side a joined part constituted by two films sealed together. The sealed part forming the joined part is formed at the base of the joined part over the entire length of the joined part. The edge of the joined part is not sealed but forms a non-sealed part instead, and the end edge of one of the two films constituting the non-sealed part is formed longer than the end edge of the other film. The flat bag simplifies the operation of spreading a folded-up sheet stored therein by removing the sheet from the flat bag and allowing the removed sheet to be attached on the face quickly and reliably without dirtying the fingers.

Abstract: Provided are a package for a skin drug solution holding body capable of further prohibiting impregnation unevenness of a drug solution, and a method of manufacturing the same. A face mask package in which a base material 1 used by attaching it to skin is impregnated with liquid cosmetics 2, and the base material 1 and the liquid cosmetics 2 of high viscosity are placed in a packaging bag 3 and vacuum-sealed. The base material 1 is in a sheet form, and the sheet-form base material 1 is stored in a folded state in the packaging bag 3 as a flat bag. It is preferable that a chamber-type vacuum sealing machine is used for vacuum-sealing. It is also preferable that the packaging bag 3 having the base material 1 and the liquid cosmetics 2 therein is pressed, while being sandwiched, prior to vacuum-sealing.
