  • Publication number: 20050137555
    Abstract: An individual wrapping container according to the present invention prevents deformation and damage of an ineterlabial pad attached between labia accommodated in the individual wrapping container by protecting a peripheral portion of the interlabial pad. The individual wrapping container also prevents contamination of the interlabial pad before use at the time of replacement of the used interlabial pad. The interlabial pad includes the peripheral portion forming a contour of the interlabial pad. The individual wrapping container includes a protective region having higher rigidity than that of the peripheral potion of the interlabial pad accommodated in the individual wrapping container so as to protect the peripheral portion.

  • Publication number: 20040153042
    Abstract: The present invention provides an interlabial pad, which includes an absorber (13) and comprises an absorbing sheet portion (14a), which faces against the body side in wearing the pad and a support sheet portion (14b), which backs the absorber (14a). The absorber (14a) comprises of a pair of absorbing sheet bodies (16) which are divided along the substantial center line of the interlabial pad 14, the absorbing sheet (16) and the impermeable support sheet (12) are bonded with each other on the peripheral edge portion (15) of the interlabial pad (14) to form a void portion (18) between the absorbing sheet body (16) and the support sheet (12) through which the menstrual blood can flow into. Thereby the menstrual blood flowing down along the inner wall of the labia can be rapidly transferred into the absorber and the shape fitness (fitting ability) of the pad in labia can be improved.
