  • Patent number: 10130522
    Abstract: A method for manufacturing a disposable worn article including the steps of: carrying a continuous sheet (W1) continuous in a carrying direction (X1); placing elastic members (F3), continuous in the carrying direction of the continuous sheet, on the continuous sheet with the continuous elastic members stretched; placing discontinuous sheets (W2), each of which has a predetermined length, on the continuous sheet intermittently and successively in the carrying direction so that the continuous elastic members are sandwiched between the discontinuous sheets and the continuous sheet; and carrying out a first joining step in which, in an area where each of the discontinuous sheets is placed, the continuous sheet, each of the discontinuous sheets, and the continuous elastic members are joined to one another, intermittently in the carrying direction, along first joining portions (32A, 32C) extending in a width direction (Y) crossing the carrying direction.

  • Patent number: 10052241
    Abstract: A disposable absorbent article utilized for absorption and containment of urine and other body exudates may incorporate components that may be detached from the article after use to provide disposal options based upon the user's preferences and circumstances, such as flushing down a toilet or septic tank, composting, recycling, or disposing in a landfill. Sanitary grips and sanitary gap may provide sanitary placements to detach the article. Ripping features incorporated along the top liner, back liner, or outer liner enclosure may also be used to detach the article. A removable liner may be detached from the top liner or outer liner enclosure. The absorbent core may be released after the article has been detached. To reduce the risk of clogging the toilet, a membrane may be utilized to create a barrier between the absorbent core and high-absorbency material to obstruct the high-absorbency material from being released and flushed.
