Abstract: PURPOSE:To obtain the absorptive articles having excellent thermal adhesiveness, hole resistance and flexibility by consisting 1st and 2nd films of thermoplastic resins, of which the resin consisting the 2nd film has the melt index value lower than the melt index value of the resin constituting the 1st layer and forming the 1st and 2nd films in such a manner that the resin having the specific melting temp. do not exist at the ratio higher than a specific ratio. CONSTITUTION:The absorptive articles have a front sheet having liquid permeability, a rear sheet having liquid impermeability and an absorber positioned between the two sheets. The rear sheet has the 1st film which is in contact with the absorber and the 2nd film which is adjacent to the 1st film and is integrated with the 1st film. The 1st and 2nd films consist of the thermoplastic resins. The resin constituting the 2nd film has the melt index value lower than the melt index value of the resin constituting the 1st layer; in addition, the resins having the melting temp. higher than 150 deg.C do not exist at >=30% of the entire of the 1st and 2nd films in the films. The absorptive articles are excellent in all of the adhesiveness, hole resistance and flexibility.

Abstract: PURPOSE:To obtain the absorptive article which can be put on easily to lingerie and can prevent effectively a horizontal leakage by providing an adhesive part on the reverse sides of a pair of fixing pieces, respectively, and making the fixing piece freely contactable and separable with and from the reverse side of an absorptive article main body through the adhesive part. CONSTITUTION:In both the left and the right side edge parts, respectively in the longitudinal direction of a sanitary napkin 1, an extended part extending to the outside in the width direction is bent and formed so that each free leg 7A, 7B comes into contact with each other in the center in the longitudinal direction of the sanitary napkin 1 main body, and a fixing implement 7 inserts and holds both side edge parts 6A, 6A of a crotch part 6 of shorts 5 between each wing part 7C, 7C and the reverse side of the sanitary napkin main body, and fixes the sanitary napkin 1 main body to the crotch part 6. Also, adhesive parts 8, 9 are provided on the reverse sides of each wind part 7C, 7C of the fixing implement 7 and the face of the fixing implement 7 main body opposed to these faces, respectively, and sticking the fixing implement 7 to the shorts 5 by these adhesive parts 8, 9, the sanitary napkin 1 main body can be fixed surely to the shorts 5.

Abstract: PURPOSE:To facilitate the installation to shorts, to hold the wearing state at the time of start of use, and to prevent a leakage by providing a fixing tool having a free end piece having no fixing adhesive part, and also, for fixing an absorptive article to shorts on a non-skin abutting face side of the absorptive article, and positioning the free end of the fixing tool in the inside from a side part in the longitudinal direction of the fixing tool. CONSTITUTION:Fixing pieces 7C, 7C of a fixing tool 7 are stretched to the outside from a sanitary napkin 1 main body and the sanitary napkin 1 is placed against a crotch part 6 of shorts 5. By a stress in each side part 7A, 7A, each fixing piece 7C, 7C is returned naturally to its original state and wraps in both side edges 6A, 6A of the crotch part 6, and the sanitary napkin 1 is installed in the crotch part 6. When a user puts on the shorts 5 and the crotch part 6 is pressed against the groin part of the user, the sanitary napkin 1 deformed like a saddle in accordance with a shape of the groin part and adheres closely to the groin part. The fixing piece 7C, 7C are drawn out easily and surely and the sanitary napkin 1 can be installed in the crotch part, and a use state of the sanitary napkin is stabilized, and the sanitary napkin 1 is prevented from being twisted.

Abstract: PURPOSE:To effectively prevent leakage from a crotch part and leakage from a hip part by extending flexible lug pieces from both breadthwise directional side edges at positions deviated in the longitudinal direction of the subject absorbent article. CONSTITUTION:Since flexible lug pieces 2 are extended from both the breadthwise directional side edges at the positions deviated in the longitudinal direction of an absorbent article 1, the length of one part of an absorber, which is the part rear from parts of the lug pieces to almost coincide with a point on which a liquid is to be excreted, becomes longer as compared to the length of the other part of the absorber, namely, the part front from the above-mentioned parts of the lug pieces. Namely, while the longitudinal directional center line of the absorbent article 1 substantially coincides with a longitudinal directional center line A-A' of the lug pieces 2 in a conventional absorbent article, a longitudinal directional center line B-B' of the absorbent article 1 never substantially coincides with a longitudinal directional center line C-C' of the lug pieces 2 in the absorbent article as this invention. Consequently, in fitting the article, an area to cover the hip part relatively increases as compared to the area of a pubis part, and even when the length of the absorber is equal to or slightly shorter than that of the conventional absorbent article, the leakage from the hip part can be extraordinarily suppressed.
