An absorbent article has a substantially elongated shape and includes a topsheet 2, a backsheet 3, and an absorbent member 4. The topsheet 2 includes a sheet member which has one surface 2a exhibiting hydrophobic properties and another surface 2b exhibiting hydrophilic properties. The one surface of the topsheet is a skin contactable surface, and the other surface faces the absorbent member 4. The backsheet serves as an anti-leakage sheet and is disposed at opposing longitudinal side portions of an upper surface of the absorbent article inwardly from side edges 1a of the absorbent member so that the backsheet forms a pair of hydrophobic areas A. Each of the hydrophobic areas A has a continuous or discontinuous sealed portion 10 formed by sealing the topsheet 2 and the backsheet 3 along each inner edge A' of each hydrophobic areas A. A body fluid retaining portion 20 is provided at a location lying outside of the sealed portion 10 on the skin contactable surface of the absorbent article. The body fluid retaining portion 10 is formed by folding the topsheet 2 so that the hydrophilic surface 2b forms the inside of the fold.

A wrapping construction of an absorbent article includes a sanitary napkin 2 as an absorbent article including a body 3, and a pair of left and right wing portions 4,4 disposed on opposing left and right sides of the body 3. The body 3 is provided on a skin non-contacting surface 32 side thereof with a body adhesive portion 37. Each of the wing portions 4,4 is provided on a skin non-contacting surface 32 side thereof with a wing adhesive portion 41. The construction further includes a wrapping material 5 for individually wrapping the sanitary napkin. The method of making the wrapping construction includes the steps of: the wing portions 4,4 being folded towards a skin contacting surface side 31 of the body 3; the body adhesive portion 37 being in contact with and peelably adhered to an inner surface 54 of the wrapping material 5; the wrapping material 5 being allowed to extend at opposing left and right side edge portions 52, 52 and a front end edge 51 thereof outwardly of opposing side edges 3b, 3b and a front end edge 3a of the body 3, respectively; the sanitary napkin 2 and the wrapping material 5 being folded by gradually folding from rear end edge sides 3c thereof with the skin contacting surface 31 sides facing inwardly; and an outer surface 55 of the wrapping material 5, with which the end edge side 3c of the body 3 being in contact, being peelably adhered to said wing adhesive portions 37.
摘要:
An absorbent member in an absorbent article comprises a absorbent polymer and cellulose fibers. The absorbent polymer has a centrifugal retentive capacity for physiological saline of 30 g/g or more and a permeation rate of physiological saline of 10 ml/minute or more. The cellulose fibers are crosslinked cellulose fibers obtainable by an intramolecular and/or intermolecular crosslinking of the cellulose fibers. Particularly, an absorbent member in a sanitary napkin has a centrifugal retentive capacity of pseudo-blood of 30 g or more and a permeation rate of pseudo-blood of 50 ml/minute or more. Also, a topsheet in the absorbent article comprises a liquid-permeable sheet, which comprises at least a layer in contact with a user's skin and a layer not in contact with the user's skin, the layers being overlaid and combined with each other into a unitary body. The layer in contact with the user's skin comprises a porous film of a thermoplastic resin or a nonwoven fabric of synthetic fibers. The layer not in contact with the user's skin comprises an absorbent sheet, which comprises at least bulky cellulose fibers. The absorbent member and the topsheet should preferably comprise crosslinked cellulose fibers.
摘要:
An absorbent article which comprises an absorbent element which at least partially comprises an absorbent sheet A prepared by applying a pressure-sensitive adhesive 3 having a suitable adhesive power to an absorbent material 1 having a suitable liquid-absorbent (or retentive) power in the form of dot, line or curve (spiral curve or the like) with the pressure-sensitive adhesive in a suitable density; spreading an absorbent polymer 2 thereon; putting another sheet of the absorbent material 1 thereon, and compressing the assemblage into a composite structure. In the course of the absorption of a liquid, the liquid is first stocked in the absorbent material having a high initial absorption velocity, and is gradually transferred to the absorbent polymer by capillary power as the driving force and absorbed therein, while the absorbent polymer is prevented from falling off from the absorbent material by the pressure-sensitive adhesive, whereby the properties of the absorbent polymer can be exhibited to the fullest.
摘要:
A substantially elongated absorbent article having a liquid permeable topsheet, a liquid impermeable backsheet, an absorbent member interposed between the topsheet and the backsheet, and a pair of hydrophobic areas along opposing longitudinal side portions of an upper surface of the absorbent article inwardly from longitudinal side edges of the absorbent article, the hydrophobic areas each having a continuous or discontinuous antileakage groove formed along a respective one of the longitudinal side portions, wherein a width of each of the antileakage grooves is from 0.1 mm to 20 mm, a ratio of a depth of each of the antileakage grooves with respect to a thickness of a portion of the absorbent article where no antileakage groove is formed is from 0.01 to 0.8, and the depth of each of the antileakage grooves is from 0.1 mm to 12 mm.
