Disposable wearing article

A disposable wearing article comprising:

• a front body section;
• a back body section,
• a waist opening;
• a pair of leg openings;
• and
• a pair of side seals formed by putting an interior face of the front body section and an interior face of the back body section together and melt-bonding the front and back body sections along opposed lateral edge zones thereof, each of the side seals having melt-bonded areas arranged at intervals in a specific pattern,
• wherein each of the side seals comprises a first line of first melt-bonded areas and non-melt-bonded areas alternately arranged in a front-back direction, each of the first melt-bonded areas having a shape elongated in a front-back direction, the first line being positioned on an innermost side in a width direction of the side seal, and a second line of second melt-bonded areas arranged at intervals in the front-back direction, each of the second melt-bonded areas having a shape elongated in the front-back direction, the second line being positioned adjacent outward in the width direction of the first line with a non-melt-bonded zone intervening therebetween, the non-melt-bonded zone extending continuously in the front-back direction,
• wherein the first melt-bonded areas and the second melt-bonded areas are disposed in a staggered arrangement so that the second melt-bonded areas are positioned outward in the width direction of the non-melt-bonded areas,
• wherein a dimension in the front-back direction of each first melt-bonded area is 0.5 to 2.0 mm,
• wherein a dimension in the width direction of the first melt-bonded area is 0.1 to 0.8 times the dimension in the front-back direction of the first melt-bonded area,
• wherein a minimum dimension in the front-back direction of each non-melt-bonded area is 1.0 to 2.5 mm,
• wherein a dimension in the front-back direction of each second melt-bonded area is 0.2 to 1.0 time the minimum dimension in the front-back direction of the non-melt-bonded area,
• wherein a dimension in the width direction of the second melt-bonded area is 0.2 to 0.6 times the dimension in the front-back direction of the second-melt-bonded area,
• wherein a center in the front-back direction of the second melt-bonded area is positioned on a line passing a center in the front-back direction of the non-melt-bonded area and extending in the width direction, and
• wherein a minimum dimension in the width direction of the non-melt-bonded zone is 0.1 to 0.6 times the minimum dimension in the front-back direction of the non-melt-bonded area.

• wherein the first melt-bonded areas and the second melt-bonded areas are disposed in a staggered arrangement so that the second melt-bonded areas are positioned outward in the width direction of the non-melt-bonded areas,
• wherein a third line of third melt-bonded areas arranged at intervals in the front-back direction is positioned adjacent outward in the width direction of the first line with the non-melt-bonded zone intervening therebetween,
• wherein the second melt-bonded areas and the third melt-bonded areas are spaced apart from each other,
• wherein an area of each third melt-bonded area is larger than an area of each first melt-bonded area and then an area of each second melt-bonded area, and
• wherein a minimum distance between a first melt-bonded area and a second melt-bonded area closest thereto is shorter than a minimum distance between the first melt-bonded area and a third melt-bonded area closest thereto and then a minimum distance between the second melt-bonded area and a third melt-bonded area closest thereto.
