Abstract
A pet diaper extending in a lateral direction along a waist of a pet and in a longitudinal direction from a ventral side to a dorsal side of the pet, the lateral direction being orthogonal to the longitudinal direction, and the pet diaper including: a main body including an absorbent core and a tail hole configured to pass feces of the pet; and a first elastic string attached to the main body in a stretched state and extending at least from a ventral-side edge of the tail hole and a dorsal-side edge of the absorbent core in the longitudinal direction.
Claims21
A pet diaper extending in a lateral direction along a waist of a pet and in a longitudinal direction from a ventral side to a dorsal side of the pet, the lateral direction being orthogonal to the longitudinal direction, and the pet diaper comprising:
- a main body including an absorbent core and a tail hole configured to pass feces of the pet;
- and
- a first elastic string attached to the main body in a stretched state and extending at least from a ventral-side edge of the tail hole to a dorsal-side edge of the absorbent core in the longitudinal direction.
A method for continuously manufacturing a pet diaper extending in a lateral direction along a waist of a pet and in a longitudinal direction from a ventral side to a dorsal side of the pet, the lateral direction being orthogonal to the longitudinal direction, the method comprising:
- conveying, in a conveyance direction along the longitudinal direction, a belt-shaped top sheet composed of top sheets continuous with each other in the longitudinal direction, and a belt-shaped back sheet composed of back sheets continuous with each other in the longitudinal direction;
- attaching a pair of elastic strings to the belt-shaped back sheet in a stretched state in the longitudinal direction;
- forming a main body complex including:
- the belt-shaped top sheet;
- the belt-shaped back sheet to which the pair of elastic strings are attached;
- and
- a plurality of the absorbent cores arranged at a predetermined interval in the longitudinal direction between the belt-shaped top sheet and the belt-shaped back sheet;
- forming a tail hole by cutting the main body complex along a cutting line at a position between the pair of elastic strings;
- and
- after forming the tail hole, cutting the main body complex including the pair of elastic strings along the lateral direction to form the pet diaper including each of the top sheets, each of the back sheets, and each of the absorbent cores, wherein
- the cutting line has a U-shape opening in a direction opposite to the conveyance direction, a U-shape opening in the lateral direction, or a ring shape.
