Abstract
The present invention relates to a paper box formed from blanks of cardboard having an inner bag, and more particularly to a moisture proof container which performs a function of simultaneously opening an outer box and an inner bag, in which the outer box and the inner bag may be opened simultaneously without deforming the outer box by opening an opening place formed by tear-away lines bored from a top panel to a front panel of the outer box. The invention provides a moisture proof container with an outer box and an inner bag which may be opened simultaneously, comprising an outer box formed from blanks of cardboard or the like and an inner bag formed from blanks of moisture proof sheet material, characterized in that opening tear-away lines are bored from a top panel to a front panel of the outer box, the inner bag has its opposed ends of the moisture proof material overlapped and adhered together to form a cylindrical body, and one end of the material is struck on the surface within the outer box so that the end is positioned in the opening place of the outer box.
