Abstract: A stretchable structure is provided with an elastic member provided between a first sheet layer and a second sheet layer. A stretchable region and a non-stretchable region are alternatively repeated three or more regions from end to end in the stretching direction of the stretchable structure. Both ends are the stretchable region. Both of the ends have an adhesive region of a hot melt adhesive, where the elastic member is adhered to the first sheet layer and the second sheet layer, in a spread state, intervals between adhesive regions adjacent in the stretching direction are all the same, twice of a stretching direction length of the adhesive region positioned on both ends in the stretching direction of the stretchable structure and a stretching direction length of the adhesive region positioned at an end portion on the non-stretchable region side of the stretchable region are all the same.

Abstract: A household-use tissue storage container includes: a container body that stores household-use tissue inside and has an outlet through which the household-use tissue is taken out; and an open/close lid that is pivotably provided on the container body and closes the outlet. The container body includes: a latch that latches the closed open/close lid and that unlatches and opens the open/close lid; and a biasing means that biases the open/close lid in an opening direction. The container body has a part made of an elastic material and a brake that is integrally formed with the elastic part and in contact with the open/close lid in an opened state. Alternatively, the open/close lid has at least a part made of an elastic material and a brake that is integrally formed with the elastic part and in contact with the container body when the open/close lid is opened.

Abstract: A stretchable member has a second sheet layer with an exposed portion, first sheet layer, and elastic sheet interposed therebetween. The second and the first sheet layers are joined at multiple sheet joining portions arranged at intervals through joining holes penetrating the elastic sheet or via the elastic sheet, and vent holes each opened at least in a spread state by displacement of the edge of each joining hole away from the circumferential edge of each sheet joining portion in the stretchable direction ED. The colors of the external surface of the elastic sheet and of portions of the external surface of the first sheet layer observed through the vent holes are observable through the second sheet layer, and the color difference ΔE between the colors of the external surface of the elastic sheet and of the external surface of the first sheet layer is 30 or more.

Abstract: A fine cellulose fiber-containing substance that has excellent dispersibility in water and can be manufactured easily. A method is for manufacturing the fine cellulose fiber-containing substance, and a method is for manufacturing a fine cellulose fiber dispersion. A fine cellulose fiber-containing substance contains fine cellulose fibers into which a phosphite containing a cation of an inorganic substance is introduced. The ratio of the cation of the inorganic substance with respect to 1 g of the fine cellulose fibers is 0.14 mmol or more. In manufacturing the fine cellulose fiber-containing substance, a phosphite is introduced into cellulose fibers, and then the cellulose fibers are defibrated to obtain a dispersion containing fine cellulose fibers, during which an alkali metal ion-containing substance is added to the cellulose fibers, and the dispersion is concentrated. In manufacturing a fine cellulose fiber dispersion, the fine cellulose fiber-containing substance is mixed with water.

Abstract: A cover nonwoven fabric covers a back surface of an inner member from between a front side outer member and the inner member to between a back side outer member and the inner member. In this cover nonwoven fabric, a large number of holes are provided at intervals. The holes penetrate the front surface and back surface from between the front side outer member and the inner member to between the back side outer member and the inner member. The front side outer member and the back side outer member have, at least at portions overlapping with the cover nonwoven fabric and not having any elastic member, a total luminous transmittance of 50% or more.

Abstract: A home tissue paper accommodation container includes a container body having an accommodation space. The container body includes a container body upper part and a container body lower part which are connected to each other by a connection part and integrally formed. The container body upper part and the container body lower part can be detachably combined with respect to each other so as to seal the accommodation space. The connection part connects surfaces oriented in the same direction in a state in which the container body upper part and the container body lower part are combined with each other. The connection part connects a position separated from the lower end of the container body upper part and a position separated from the upper end of the container body lower part to each other.

Abstract: A fine cellulose fiber in which when the fine cellulose fiber is formed into a dispersion, the dispersion has very high light transmittance and viscosity, and a method for producing the fine cellulose fiber.
The fine cellulose fiber has a fiber width of 1 to 200 nm. A part of hydroxy groups of the cellulose fiber are substituted with a predetermine functional group to introduce an ester of phosphorus-oxo acid, and the introduction amount of the functional group is more than 2.0 mmol per 1 g of the cellulose fiber. For producing the fine cellulose fiber, to cellulose fiber is added a solution having a pH of less than 3.0 and including an additive (A) containing at least one of a phosphorus-oxo acid and a phosphorus-oxo acid metal salt and an additive (B) containing at least one of urea and a urea derivative, and the mixture is heated to perform fibrillation.-

Abstract: On a skin-contact surface on a front-surface side of a sanitary napkin 1, in a plan view, a concave low compression part 10 obtained by denting, from a skin-contact surface side, a closed region part partitioned by an inside curve 12 formed of a curved line swelling on a front end side of the sanitary napkin 1, and an outside curve 13 that is located on a front end side than the inside curve 12, is formed of a curved line swelling on a front end side of the sanitary napkin 1 and has both ends that are connected respectively to the both ends of the inside curve 12 is formed. In the low compression part 10, a plurality of high compression parts 11 formed discretely respectively along the inside curve 12 and outside curve 13 is formed. The high compression parts 14 formed along the inside curve 12 are arranged over an entire length of the inside curve 12, and the high compression parts 15 formed along the outside curve 13 are arranged on a center part of the outside curve 13, and the high compression parts are not arranged at both end parts of the outside curve 13. Sanitary napkin 1 makes it easy to deform along a shape of a body and make it difficult to generate twists or leakage.
