Abstract: An object of the invention is to improve the diffusibility of body fluid such that the body fluid can be quickly absorbed. The sanitary napkin 1 represented by FIG. 3 includes an absorbing body 4 with a highly water-absorbent polymer 12 interposed between an upper layer sheet 10 disposed on the skin side and a lower layer sheet 11 disposed on the non-skin side. The upper layer sheet 10 has a plurality of first protrusions 14 forming first space parts 13 that are to be filled with the highly water-absorbent polymer and that expand to the skin side, and a plurality of second protrusions 16 forming second space parts 15, each of which having a smaller volume than each of the first space part 13, that are to be filled with the highly water-absorbent polymer and that expand to the skin side. The weight per unit area of the highly water-absorbent polymer 12 filled into the second space parts 15 is made smaller than the weight per unit area of the highly water-absorbent polymer 12 filled into the first space parts 13.

Abstract: An absorber 4 is interposed between a front-surface sheet 3 and a back-surface sheet 2, and side sheets 7 are respectively disposed along a longitudinal direction on both side parts of a skin side. The front-surface sheet 3 contains non-thermally fusible fiber, and the back-surface sheet 2 and the side sheets 7 contain thermally fusible resin. Fusion parts 10 allowing the side sheets 7 and the back-surface sheet 2 to be thermally fused under a state of the front-surface sheet 3 interposed therebetween are arranged in areas corresponding to side parts outer than the absorber 4 in a width direction, and the areas include the front-surface sheet 3 interposed between the side sheets 7 and the back-surface sheet 2, and include at least front and back end parts of a sanitary napkin 1. The front-surface sheet is prevented from delaminating and tearing accompanied therewith when non-thermally fusible fiber is used in the front-surface sheet.

Abstract: A container for housing household tissue paper includes a container body that stores household tissue paper inside. The container body has an upper container body that forms an upper portion of the container body and a lower container body that forms a lower portion of the container body. The upper container body has an outlet through which the household tissue paper is taken out and an open/close lid that seals the outlet. A lower end of the upper container body and an upper end of the lower container body are connected to each other, and the upper container body and the lower container body are pivotable with respect to each other.

Abstract: A container for housing household tissue paper includes a container body that stores household tissue paper inside and has an outlet through which the household tissue paper is taken out, an open/close lid that is pivotably provided to the container body and closes the outlet, and a biasing member. At least a part of the container body is formed of an elastic material. The container body has a latch that latches the open/close lid in a closed state and releases and opens the open/close lid. The biasing member is formed of the elastic material integrally with the part of the container body formed of the elastic material and biases the open/close lid in an opening direction.

Abstract: This disclosure makes it possible to form embossments with good appearance even when a polymer sheet is used as an absorber and makes it possible to reliably implement the function of the embossments. A sanitary napkin (1) includes a polymer sheet (4) including a superabsorbent polymer (12) disposed between an upper-layer sheet (10) disposed on a skin side and a lower-layer sheet (11) disposed on a non-skin side, and an embossment (20) that is formed on a skin-side surface of the polymer sheet (4) along a longitudinal direction of the sanitary napkin (1) and is shaped like a discontinuous line formed by arranging compressed parts (21) and non-compressed parts (22) alternately. The ratio A:B of a length (A) of each of the compressed parts (21) to a length (B) of each of the non-compressed parts (22) is between 7:1 and 1:1.

Abstract: A disposable wearable article includes an elastic film stretchable structure in which an elastic film is laminated between a first sheet layer and a second sheet layer. The first sheet layer and the second sheet layer are bonded to each other through holes passing through the elastic film with many bonded portions arranged at intervals. A region having the elastic film stretchable structure includes a stretchable region that elastically stretches and contracts together with the elastic film. The stretchable region includes a plurality of elastic films disposed so as to have an overlapping portion. The number of laminated layers of the elastic film in a region located in an intermediate portion of the stretchable region in an orthogonal direction (XD) orthogonal to a stretchable direction (ED) is different from that in each of second regions adjacent to both sides of the first region.

Abstract: In order to prevent degradation of appearance, prevent a decrease in flexibility, and improve non-elasticity in a non-stretchable region in an elastic film stretchable structure, the invention is characterized by having an elastic film stretchable structure (20X) formed by stacking an elastic film (30) between a first sheet layer (20A) and a second sheet layer (20B), wherein a region having the elastic film stretchable structure (20X) includes a non-stretchable region (70) and a stretchable region (80) provided at least at one side of the non-stretchable region (70) in a stretching and contracting direction, the stretchable region (80) being stretchable in the stretching and contracting direction, the first sheet layer (20A) and the second sheet layer (20B) are joined via through holes (31) penetrating the elastic film (30) at the large number of sheet bond portions (40) arranged at intervals, and the non-stretchable region (70) does not have a section in which the elastic film (30) linearly continues along the stretching and contracting direction, due to presence of the through holes (31), even though the elastic film (30) continues in the stretching and contracting direction.
