Abstract

(57) [Summary] An adhesive tape adhered between an outer inner crotch portion of a short and a fastening blade is easily peeled off due to a frictional force between a wearer's right and left crotch, for example, walking. Kind Code: A1 A cloth fastening blade protruded laterally in both directions of a napkin body is formed to have a length that overlaps when folded to the back side of the napkin body, and an adhesive is adhered to the back surface. By so doing, the left and right fastening blades cover the inner crotch of the sanitary shorts, and the napkin body is securely and firmly connected to the sanitary shorts.

Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a sanitary napkin.

[0002]

[Prior art]

 As a conventional sanitary napkin, in order to prevent slippage and menstrual leakage during mounting, on both sides of the napkin main body, short piece-shaped fastening blades for fastening to the outer surface of the sanitary shorts are turned sideways. An adhesive tape is attached to the back of the fastening feather and the napkin body is placed on the inner surface of the inner crotch of the sanitary shorts, and the fastening feather is bent to the outer surface of the inner crotch of the short. A structure in which the adhesive tape is used is known (Japanese Utility Model Application Laid-Open No. 62-12322).

[0003] That is, it has been proposed that a major cause of the displacement of the napkin body is eliminated by fixing the fastening blades to both sides of the outer surface of the inner crotch portion of the shorts with an adhesive tape.

[0004]

[Problem to be solved]

 In general, a sanitary napkin is ideally a napkin whose mounting position can always be kept constant so that menstrual blood can be smoothly absorbed by the absorber and its silhouette is not impaired.

However, the conventional sanitary napkin with fastening feathers has a protruding length of about 1 cm at most, and is adhered and fixed to the outer edge of the inner crotch part of the sanitary shorts. There is a drawback that the adhesive tape adhered between the outer inner crotch portion of the shorts and the napkin blade is easily peeled off due to a weak force and a frictional force between the wearer's left and right crotch, for example, walking.

[0006] As a result, the body is tilted to the right or left, the leakage prevention effect is lost, and menstrual blood flows out of the napkin as it is, causing a spillover phenomenon.

[0007] Furthermore, the same phenomenon that there is no fit during bedtime is the same phenomenon, and there is a problem that this is a major cause of falling down.

[0008]

[Means for solving the problems]

 In order to solve the above-mentioned problems, the present invention is designed to make the cloth fastening blades projecting sideways in both directions of the napkin body overlap each other when they are bent to the back side of the napkin body. By forming the length and sticking the adhesive on the back, the left and right fastening feathers cover the inner crotch of the sanitary shorts firmly, and the napkin body is securely and firmly connected to the sanitary shorts. It was configured as follows.

[0009]

[Embodiment of the invention]

 A sanitary napkin with cloth fastening blades protruding laterally on both sides of the napkin body is formed to a length that overlaps when folded on the back side of the napkin body, and an adhesive is adhered to the back surface. With the napkin main body placed on the inner surface of the inner crotch part of the sanitary shorts, the left and right fastening blades are bent toward the outer surface of the sanitary shorts, and one of the fastening blades is made of the sanitary shorts with the adhesive material. The left and right fastenings that are adhered to each other and also to the sanitary shorts by bonding the other fastening blade on top of this one fastening blade and gluing it with the adhesive. The feathers cover the inner crotch of the sanitary shorts firmly, and the napkin body is securely and firmly fixed to the sanitary shorts to prevent the sanitary napkin from slipping and prevent menstrual blood from leaking sideways. And possible It was.

[0010]

【Example】

 As shown in FIG. 1, the napkin main body 1 is formed in a substantially rectangular shape whose both ends in the long side direction form an arc shape, and is configured by mounting an absorbing member 3 on a nonwoven fabric 2 serving as a base.

[0011] Fastening blades 4a and 4b made of a cloth such as a waterproof woven cloth or a non-woven cloth are provided on both sides of the napkin body 1 in the longitudinal middle thereof so as to protrude laterally.

The fixing blades 4 a and 4 b extend from a blade support 5 made of a cloth such as a woven fabric or a non-woven fabric subjected to waterproof processing attached to the lower surface of the napkin main body 1, and are bent to the back side of the napkin main body 1. Sometimes, the adhesive is formed to have a length (about 30 mm to 50 mm) such that they overlap each other at least at the front end portion or the entire surface, and the adhesive material 6 is preferably applied to the entire back surface or the front end portion and the base portion.

When the adhesive material 6 is adhered to a cloth such as a sanitary shorts 7 on which a sanitary napkin is attached and peeled off, the adhesive material 6 has a relatively weak adhesive force that does not have a strong adhesive force so as to make a crunchy sound. When a prototype was made and tested, a commercially available Nichiban Co., Ltd. strong double-sided adhesive tape was used, and the weak surface was adhered to the fixing blades 4a and 4b with a strong surface. As a result, good adhesion was obtained so that it could be smoothly peeled off without making any sound to the cloth.

When using the sanitary napkin of the present invention, the left and right fastening blades 4 a and 4 b are attached to the outer surface of the sanitary short 7 while the napkin main body 1 is placed on the inner surface of the inner crotch portion of the sanitary short 7. Side, and one of the fastening blades 4a is adhered to the outer surface of the sanitary shorts with the adhesive material 5, and the other fastening blade 1b is overlaid on the one fastening blade 4a and the adhesive material 5 is attached thereto. The left and right fastening blades 4a and 4b adhered to each other and also adhered to the sanitary shorts 7 completely cover the circumference of the inner crotch portion of the sanitary shorts 7, and the napkin body 1 is sanitized. Securely and firmly fixed to the shorts 7 for use.

As a result, the sanitary napkin is firmly fixed without being peeled off by the frictional force between the left and right groins, such as when walking, and can be used extremely favorably and stably without causing side leakage.

[0016]

[Effect of the invention]

 As described above, according to the present invention, the entire periphery of the inner crotch portion of the sanitary shorts is firmly covered by the left and right fastening blades that are adhesively bonded to each other and also adhered to the sanitary shorts, and have a relatively weak adhesive force. Even if the adhesive material is used, the napkin body can be securely and firmly fixed to the sanitary shorts.

As a result, it is possible to reliably prevent the napkin body from slipping due to the frictional force between the right and left crotch while walking or sleeping while wearing the napkin, and to prevent menstrual blood from spilling over. And a sense of security can be obtained.
