Document Type and Number:
WIPO Patent Application WO/2017/159262
Kind Code:
A1
Abstract:
The present invention addresses the problem of enabling a softer feel to be obtained when a product in the natural length state thereof is touched by a hand. This stretch structure for an absorbent article has two sheet layers (12S, 12H) extending in a stretch direction and an orthogonal direction orthogonal to the stretch direction, and a plurality of narrow elastic stretch members (19) which extend along the stretch direction and are disposed at an interval in the orthogonal direction between the sheet layers (12S, 12H), both end parts in the stretch direction of the elastic stretch members (19) being configured as fixed end parts (19f) fixed to the two sheet layers (12S, 12H), the elastic stretch members (19) having sheet joining parts (20) in which the two sheet layers (12S, 12H) are joined via a hot-melt adhesive (H2) in inter-fixed-end-part regions (MA) between the fixed end parts (19f), and the sheet joining parts (20) being a plurality of linear sheet joining parts (20) which are each continuous in the stretch direction and are arranged in the orthogonal direction without intersecting with each other.
