Abstract:
1. A package comprising: a substantially cuboidal outer box having an open top and a to-be cutout portion separably formed in an upper region of a front wall thereof, the to-be cutout portion forming a cutout connecting with the open top when the to-be cutout portion is separated from the front wall of said outer box; a tongue lid rotatably joined to a rear edge of the open top by a lid hinge, said tongue lid including a lid for covering the open top and a tongue for covering the upper region of the front wall of said outer box; and a substantially cuboidal inner pack placed inside said outer box, said inner pack including a wrapper airtightly enclosing a content of said inner pack, the wrapper having a first film layer sandwiched between a paper layer and a second film layer for heat sealing, an overlap provided at an upper location of a front face of said inner pack, the overlap being formed by folding the wrapper and having inner and outer overlap portions overlapped to each other, substantially-parallel two opening developing lines extending across a top face of said inner pack and then further extending from the top face of said inner pack to the overlap, an opening start line extending in the outer overlap portion of the overlap and connecting to the opening developing lines at both ends thereof, and a heat-sealed area formed in the overlap to surround the opening start line, by heat-sealing the inner and outer overlap portions of the overlap, wherein an outer face of the outer overlap portion is bonded to an inner face of the tongue via the to-be cutout portion, at a location above the opening start line within a region of said overlap surrounded by the heat-sealed area, the opening developing lines each is formed by making a half-cut line in the wrapper in a manner that the cut does not penetrate through the wrapper, and the opening-start line is formed by making a full-cut line through the outer overlap portion of the overlap.
