Absorptive article having wing members, and process for manufacturing the same

An absorptive article comprising:

• a body including a liquid-permeable top sheet, a back sheet and an absorbent layer sandwiched between said top sheet and said back sheet;
• and
• wing members having a moisture permeability of no less than 10,000 g/m2 in accordance with JIS-Z-0208 extending outwards in a latitudinal direction from said body;
• wherein said top sheet and said back sheet extend beyond the periphery of said absorbent layer to have a peripheral joint portion in which said top sheet and said back sheet are adjoined together without having the wing members therebetween, and further extend outwards in the latitudinal direction such that protruding portions are formed,
• each wing member is jointed to a corresponding one of two protruding portions of said body while being sandwiched between said top sheet and said back sheet,
• a latitudinal dimension of joint regions between said top sheet and said wing members and a latitudinal dimension of joint regions between said back sheet and said wing members are at least 5 mm,
• at an intermediate region of said body to which said wing members are attached, said top sheet has a larger latitudinal dimension than that of said back sheet so that the joint regions between said top sheet and said wing members have a larger latitudinal dimension than that of the joint regions between said back sheet and said wing members,
• the latitudinal dimension of said joint regions between said top sheet and said wing members is at least 10 mm,
• when an area of said joint regions between said top sheet and said wing members is substantially 1 or 100%, a substantial joint area in said joint regions between said top sheet and said wing members by an adhesive is at most 0.2 or 20%, and wherein
• said top sheet and said wing members are partially welded and jointed.

An absorptive article comprising:

• a body including a liquid-permeable top sheet, a back sheet and an absorbent layer sandwiched between said top sheet and said back sheet;
• and
• wing members having a total-ray transmissivity of at least 20% in accordance with JIS-K-7105 extending outwards in a latitudinal direction from said body,
• wherein said top sheet and said back sheet extend beyond the periphery of said absorbent layer to have a peripheral joint portion in which said top sheet and said back sheet are adjoined together without having the wing members therebetween, and further extend outwards in the latitudinal direction such that protruding portions are formed, and wherein
• each wing member is jointed to a corresponding one of two protruding portions of said body while being sandwiched between said top sheet and said back sheet.
