1. A moisture proof container comprising:

  • an outer closed box formed from a blank of box material, said outer box having a wall section comprised of first and second overlapping panel sections of said blank of box material, said first panel section overlapping said second panel section on the outside of said second panel section, said outer box having a pair of spaced tear away lines through a portion thereof which includes said first panel section to define an openable panel portion;

    a substantially closed inner bag within said outer box, said inner bag formed from a blank of moisture proof uniaxially oriented sheet material having a uniaxial orientation extending in a first direction, said sheet material having a first portion and a second portion, said first portion of said sheet material prior to formation of said inner bag being spaced along said sheet material in said first direction from said second portion of said sheet material, and said sheet material being arranged to form said inner bag in a manner such that said first portion overlaps and is releasably adhered by releasable adhesive means to said second portion to define an adhered section of said inner bag, said adhered section extending in a second direction which is at right angles to said first direction of said sheet material, said substantially closed inner bag being adhesively secured within said outer box with at least a part of said sheet material adjacent to said first portion adhesively secured to said openable panel portion of said outer box, said substantially closed inner bag being secured within said outer box in a manner (i) such that the orientation of the direction of overlap of said first portion with respect to said second portion of said sheet material forming said inner bag coincides with the direction of overlap of said first panel section with respect to said second panel section of said outer box, (ii) such that said adhered section of said inner bag crosses at right angles to said spaced tear away lines of said outer box, and (iii) such that said adhesively secured part of said sheet material adjacent to said first portion is non-releasable from said openable panel portion relative to said releasably adhered first and second portions of said sheet material, and said first portion being releasably adhered to said second portion and said inner bag being adhesively secured within said outer box such that when said openable panel portion is opened by tearing along said tear away lines, said first portion between said tear away lines is released and separates from said second portion of said sheet material to thereby move with said openable panel portion with said second portion remaining in position in said outer box, whereby said inner bag is opened simultaneously with said openable panel portion.
