Abstract

An individually-packaged absorbent article or an absorbent article. The absorbent article ( 1 ) includes a hip-hold portion (H) that includes a side area ( 10 ) protruding from a rear side-edge of a body ( 8 ). The side area ( 10 ) includes a first protruding portion ( 21 ) that includes a portion having a largest width from a longitudinal centerline (CL) of the body ( 8 ), a first recessed portion ( 31 ) adjacent to the rear end of the first protruding portion ( 21 ), and a second recessed portion ( 32 ) adjacent to the front end of the first protruding portion ( 21 ). The absorbent article ( 1 ) is folded such that a mountain fold line (Y) is formed in the side area ( 10 ) of the hip-hold portion (H), and the mountain fold line (Y) intersects with an edge of the side area ( 10 ) of the hip-hold portion (H) at a position between a first inflection point (F 1 ) between the first recessed portion ( 31 ) and the first protruding portion ( 21 ) and a second inflection point (F 2 ) between the first protruding portion ( 21 ) and the second recessed portion ( 32 ), and is substantially orthogonal to the longitudinal centerline (CL).

Claims (29)

1. An individually-packaged absorbent article, comprising:

an absorbent article including a body that includes a permeable upper-side sheet, an impermeable back-side sheet, and an absorbent disposed between the upper-side sheet and the back-side sheet; and

a packaging sheet that individually packages the absorbent article, wherein

the body has a shape having a predetermined length in a longitudinal direction and a predetermined width in a direction orthogonal to the longitudinal direction;

the absorbent article includes a hip-hold portion that includes a side area protruding from a rear side-edge of the body, the side area including a first protruding portion that includes a portion having a largest width from a longitudinal centerline of the body, a first recessed portion adjacent to a rear end of the first protruding portion, and a second recessed portion adjacent to a front end of the first protruding portion;

the absorbent article is folded such that a mountain fold line is formed in the side area of the hip-hold portion; and

the mountain fold line intersects with an edge of the side area of the hip-hold portion at a position between a first inflection point between the first recessed portion and the first protruding portion and a second inflection point between the first protruding portion and the second recessed portion, and is substantially orthogonal to the longitudinal centerline.

2. The individually-packaged absorbent article as claimed in claim 1 , wherein

the side area of the hip-hold portion is folded along a longitudinal fold line extending in the longitudinal direction; and

each of

an angle formed between the mountain fold line and a straight line that passes through an intersection point of an extension of the mountain fold line with the longitudinal fold line and a bottom point of the first recessed portion, and

an angle formed between the mountain fold line and a straight line that passes through the intersection point and a bottom point of the second recessed portion

is between 30 degrees and 60 degrees.

3. The individually-packaged absorbent article as claimed in claim 2 , wherein

a slip stopper for fixing the absorbent article is provided on the back-side sheet in the side area; and

the slip stopper is disposed to cross the straight line passing through the intersection point and the bottom point of the second recessed portion.

4. An absorbent article, comprising:

a body that includes a permeable upper-side sheet, an impermeable back-side sheet, and an absorbent disposed between the upper-side sheet and the back-side sheet, wherein

the body has a shape having a predetermined length in a longitudinal direction and a predetermined width in a direction orthogonal to the longitudinal direction;

the absorbent article further comprises a hip-hold portion that includes a side area protruding from a rear side-edge of the body, the side area including a first protruding portion that includes a portion having a largest width from a longitudinal centerline of the body, a first recessed portion adjacent to a rear end of the first protruding portion, and a second recessed portion adjacent to a front end of the first protruding portion;

a mountain fold line is formed in the side area of the hip-hold portion; and

the mountain fold line intersects with an edge of the side area of the hip-hold portion at a position between a first inflection point between the first recessed portion and the first protruding portion and a second inflection point between the first protruding portion and the second recessed portion, and is substantially orthogonal to the longitudinal centerline.

5. A method of folding an absorbent article that includes a body including a permeable upper-side sheet, an impermeable back-side sheet, and an absorbent disposed between the upper-side sheet and the back-side sheet,

the body having a shape that has a predetermined length in a longitudinal direction and a predetermined width in a direction orthogonal to the longitudinal direction,

the absorbent article including a hip-hold portion that includes a side area protruding from a rear side-edge of the body, and

the side area including a first protruding portion that includes a portion having a largest width from a longitudinal centerline of the body, a first recessed portion adjacent to a rear end of the first protruding portion, and a second recessed portion adjacent to a front end of the first protruding portion,

the method comprising:

folding the absorbent article such that a mountain fold line is formed in the side area of the hip-hold portion,

wherein the mountain fold line intersects with an edge of the side area of the hip-hold portion at a position between a first inflection point between the first recessed portion and the first protruding portion and a second inflection point between the first protruding portion and the second recessed portion, and is substantially orthogonal to the longitudinal centerline.
