  • Patent number: 8146742
    Abstract: A packing body suitable as a portable packing body which can change the appearance under a state where an article is contained. The packing body (1) containing an article comprises a container main body (2) for containing an article, and an extending portion (3) extending outward of the container main body (2), with the outer side face of a central region in the height direction of the container main body (2) as the proximal end (31). The packing body (1) can be changed from a first mode where the extending portion (3) is arranged to cover the side of the first end (21) of the container main body (2) from the proximal end (31) to a second mode where the extending portion (3) is arranged to cover the side of the second end (22) of the container main body (2) by reversing the extending portion (3) along the proximal end (31). An opening (33) for exposing a second end face (24) on the side of the second end (22) at least in the second mode is formed at the extension end (32) of the extending portion (3).

  • Patent number: 6867345
    Abstract: A disposable body fluid absorbent article includes a liquid-absorbent core. The core is provided in the vicinity of opposite side edges extending in a longitudinal direction with depressed regions tapering from an upper surface toward a lower surface of the core. A density of the core components in the depressed regions is lower then or equal to a density of the core components in the remaining region of the core.

  • Patent number: 6746433
    Abstract: A disposable pull-on garment has an elasticized waist-opening and a pair of elasticized leg-openings. At least one of the inner or outer surfaces of a peripheral edge of the waist opening includes a slippage resistant sheet. The sheet has a high friction coefficient so that the peripheral edge of the waist opening is easily and reliably gripped when the garment is pulled on by a wearer.

  • Patent number: 6666851
    Abstract: A disposable garment that includes a crotch region. The crotch region has a pair of folding guides that extend transversely across a zone defined between peripheral edge portions of respective leg-openings and intersect each other in a transversely middle zone of the crotch region. The crotch region is tucked about the folding guides inwardly of the garment so that the crotch region may be divided by the folding guides into substantially triangular first and second zones defined between the peripheral edge portions of the respective leg-openings and the folding guides, respectively, a third zone extending from the folding guides into a front region, and a fourth zone extending from the folding guides into a rear region with the first and second zones being disposed between the third and fourth zones.

  • Patent number: 6635042
    Abstract: A disposable pants-type diaper is composed of a pair of sheets each having longitudinally opposite end portions extending in a transverse direction and transversely opposite side edge portions extending in a longitudinal direction. The pair of sheet are bonded together in desired zones including the transversely opposite side portions to form a disposable pants-type diaper. The pair of sheets are placed upon each other so that one of the transversely opposite side edge portions is destined to lie on a belly side of the diaper and the other thereof is destined to lie on the rear side of the diaper.
