Claims8
A sanitary tissue package comprising:
- a bundle of folded sanitary tissues stacked in a pop-up type;
- and
- a film overwrap-wrapping the bundle of the folded sanitary tissues,
- wherein a top surface part of the film includes a take-out port forming portion surrounded by a pair of first easy tear lines that extends along a width direction in which folded edges of the sanitary tissue extend and is spaced apart in a depth direction orthogonal to the width direction and a pair of second easy tear lines that extends along the depth direction and connects end portions of the pair of first easy tear lines,
- the take-out port forming portion forms a shape having
- an end portion narrowing portion in which the pair of first easy tear lines gradually approaches each other from connection portions with respect to the second easy tear lines to a side of a center portion of the bundle in the width direction and a width therebetween narrows,
- a widened portion in which the pair of first easy tear lines is gradually separated from each other from a side of the end portion narrowing portion to the side of the center portion of the bundle in the width direction and the width therebetween widens, and
- a wide portion in which the pair of first easy tear lines is gradually separated from each other to bulge outward in the depth direction at least until a length therebetween becomes longer than a length of the second easy tear lines further toward the center portion of the bundle in the width direction from the widened portion,
- by peeling off an inside of a range of the take-out port forming portion, acute corner portions are formed at positions between the first easy tear lines and the second easy tear lines, and free edge pieces including edges in a range from the end portion narrowing portion to the wide portion are formed, and
- a length between the first easy tear lines between the end portion narrowing portion and the widened portion is 10% or less of a length of the bundle in the depth direction, and a length between the first easy tear lines in the wide portion is 60% or less of the length of the bundle in the depth direction.
