The disposable pants include elastic members (thread-shaped or band-shaped elastic members for leg gathers and trunk gathers) that are stretched between two sheets (the outermost sheet and another sheet adhered to the inside). And an inner diaper disposed inside the outer diaper, the inner diaper having at least a liquid-permeable topsheet, an absorbent mat and a liquid-impermeable backsheet. ,
The outer diaper and the inner diaper are laminated, folded back and forth in two, and the left and right side edges are adhered to form a pants-type. In this disposable pants, for the purpose of enhancing the torso adhesion between the front body and the back body, the body gathers for the body gathers are provided between the positions where the elastic members for the leg gathers are arranged and the elastic members for the body gathers are arranged. There is also one in which another elastic member is attached in a stretched state substantially parallel to the elastic member to form a side gather.

れてしまってギャザーが形成されなくなる。By the way, in the step of continuously manufacturing the above-mentioned disposable pants, in which each elastic member is attached between the two sheets, first, a long sheet is made to run in the longitudinal direction, and hot melt adhesion is performed on the surface thereof. A means of applying the agent, further stacking the continuous elastic member in the stretched state on the predetermined position while curving it, stacking another sheet so as to cover it from above, and quickly crimping with a roll etc. is adopted. There is. Here, in order to bond the sheet-like or thin strip-shaped continuous elastic member to the sheet while curving the stretched elastic member, it is necessary to use a strong adhesive that can be instantaneously bonded. Since it is hardenable and has difficulty in storage and is difficult to use in industrial production, at present, a safety measure is taken in which a large amount of hot-melt adhesive having high adhesive strength is applied to the entire surface of the sheet. That is, when the adhesive strength is low or there is not a sufficient amount of adhesive, the elastic member cannot be adhered in the stretched state, loses the contracting force of the elastic member and is disengaged from the bonded portion, and gather is not formed. .

ことになる。However, since the hot-melt adhesive solidifies at room temperature, if an excessively large amount of coating is applied to the entire surface of the sheet, the laminated back sheet becomes stiff and uncomfortable to the touch when finished as a product. In particular, the central part of the pants, which corresponds to the crotch part, is sandwiched between both feet when worn, so if it does not have some flexibility, it will slip on the inner thigh and hurt the skin.

る。According to the present invention, the back sheet located at the outermost layer of the disposable pants has a laminated structure in which the elastic member is sandwiched between the two sheets in the stretched state, and the elastic member is sandwiched between the two sheets. However, in adhering these with an adhesive, it is necessary to increase the adhesive strength of the regions on both sides of the sheet (hereinafter referred to as the center of the pants at the end) than the region corresponding to the center of the pants (hereinafter referred to as the center of the pants). It is a point. That is, the middle part of the pants is where the elastic members that bend in the manufacturing process are bonded in a crossed state, but since this corresponds to the center part of the inseam, gathers are not necessary for use. Therefore, it is not necessary to increase the adhesive strength, and moreover, it is a part where flexibility is desired so as not to give discomfort to the wearer. However, the regions on both sides thereof are regions where the elastic member must be firmly fixed in order to develop the gathers for the legs and the gathers for the body.

れても良い。Therefore, in the present invention, the adhesive strength between the central portion of the pants and the areas on both sides of the pants is changed to increase the adhesive strength of the areas on both sides which must be firmly bonded. In order to increase the adhesive strength of the both side regions, a method of applying a hot melt adhesive that gives higher adhesive strength than the central portion or a method of increasing the amount of the same kind of adhesive applied than the central portion is adopted. Further, a soft adhesive having a low adhesive strength may be applied to the central portion in a larger amount than in both side areas. By adopting such a configuration, it is possible to eliminate the rough feeling due to the curing of the adhesive at the crotch part of the disposable pants, and to provide an excellent wearing feeling, and also to firmly bond the elastic members in the both side areas. A gather portion can be formed on the. 2-9mm between the center of the pants and both sides
By forming the non-adhesive-coated portion, the overlapping application of the adhesive is reliably prevented. The both side regions may be further divided into a waist vicinity portion and a central portion vicinity, if necessary.
