Abstract
A shorts-type absorbent article having leg region forming members 71, 71 arranged in an elongated state at a pair of leg regions 70 arranged around a wearer's leg, wherein each of the leg region elastic members comprises a first and a second elastic member 71a, 71b and the first and second elastic members do not exhibit elastic expansible/contractible property at least at a central area of the portion where the absorbent core exists, and the predetermined parts of the first and second elastic members are fixed to the component of the absorbent article by a second fixing means S, S.
Claims15
An absorbent article comprising a liquid-permeable topsheet, a liquid-impermeable anti-leakage sheet and a liquid-retentive absorbent core interposed between said topsheet and said anti-leakage sheet, a leg region elastic member for forming leg gathers being arranged in an elongated state thereof at a leg region arranged around a wearer's leg,
- wherein said leg region elastic member comprises a first and a second elastic member, and said first and second elastic members each include a pair of gather forming parts arranged at a pair of said leg regions and a traversing part arranged in such a manner as to traverse said absorbent core, gather forming parts of said first and second elastic members at each leg region being arranged such that said gather forming parts are oriented in opposite directions with each other,
- said gather forming parts of said first and second elastic members are fixed to a component of said absorbent article by a first fixing means, and
- said first and/or second elastic members do not exhibit elastic expansible/contractible property at least at a widthwise central area of that part of said traversing part where said absorbent core exists, and a predetermined part of said first and/or second elastic member including a portion which does not exhibit elastic expansible/contractible property is fixed to the component of said absorbent article by a second fixing means.
A shorts-type absorbent article comprising a liquid-permeable topsheet, a liquid-impermeable anti-leakage sheet and a liquid-retentive absorbent core interposed between said topsheet and said anti-leakage sheet, a leg region elastic member for forming leg gathers arranged in an elongated state at a leg region arranged around a wearer's leg,
- wherein said leg region elastic member comprises a first and a second elastic member, and said first and second elastic members each include a pair of gather forming parts arranged at a pair of said leg regions and an extension part extending from said gather forming parts towards a widthwise central area of said absorbent article,
- said gather forming parts of said first and second elastic members are fixed to a component of said absorbent article by a first fixing means,
- said extension part of said first and/or second elastic member is fixed to the component of said absorbent article by a second fixing means at a part where said absorbent core exists, and at least a portion of said extension part located at the part where said absorbent core exists exhibits elastic expansible/contractible property, and
- said first and second elastic members do not exhibit elastic expansible/contractible property at least at a widthwise central area of the part where said absorbent core exists.
A method for manufacturing a partly elasticized laminated sheet comprising the steps of applying an adhesive agent as first fixing means to at least one of two consecutive sheets which are stuck to each other in a predetermined pattern;
- sticking said two consecutive sheets together after said elastic member is introduced while oscillating said elastic member in a direction orthogonal to a flowing direction of said two consecutive sheets so that said elastic member is fixed between said two consecutive sheets through said adhesive agent;
- dividing said elastic member at a predetermined part;
- and
- fixing the predetermined part of said elastic member to at least one of said two consecutive sheets by second fixing means before or after, or at the same time said elastic member is divided.
