  With such a configuration, the surface of the sanitary napkin to which the body fluid is attached is easily covered with the front end portion and the rear end portion of the sanitary napkin, and the surface of the sanitary napkin to which the body fluid is attached touches the user's hand. This eliminates the need for clean disposal.

  Moreover, as for the sanitary napkin of this invention, a part of said bag-shaped member may protrude to the outer side of the sanitary napkin main-body part in planar view.

  With such a configuration, the front end portion and the rear end portion rise from the portion of the sanitary napkin body portion that protrudes to the outside and easily fall down, and the surface of the sanitary napkin on which the body fluid adheres is the front end portion of the sanitary napkin Since the surface of the sanitary napkin to which the body fluid is attached does not touch the user's hand, the sanitary napkin can be disposed of cleanly.

  Furthermore, the portion of the bag-like member that protrudes to the outside of the sanitary napkin main body in plan view may be located closer to the rear end than the longitudinal center of the sanitary napkin main body.

  With such a configuration, the rear end portion is further raised from the portion protruding to the outside of the sanitary napkin main body portion located closer to the rear end portion than the longitudinal central portion of the sanitary napkin main body portion, so that the sanitary napkin main body portion tends to fall down. Become. Therefore, the surface of the sanitary napkin attached with the body fluid is easily covered with the rear end portion of the sanitary napkin, and the surface of the sanitary napkin attached with the body fluid does not touch the user's hand. Will be able to.

  The sanitary napkin of the present invention is a sanitary napkin having a liquid-permeable surface material, a liquid-impermeable back material, and a liquid absorber interposed between these two members. The inside of the outer edge of the napkin forms a continuous bag portion, a string-like member is passed through the inside of the bag portion, and both ends of the string-like member are taken out of the bag portion.

  With such a configuration, there is no need to attach a continuous bag-like member to the sanitary napkin main body, so the number of parts is reduced and the manufacture of the sanitary napkin is facilitated.

  In the sanitary napkin of the present invention, a bag-like member may be provided inside the bag portion, and a string-like member may be passed through the bag-like member.

  With such a configuration, even if the discharged body fluid permeates into the sanitary napkin, the bag-like member does not penetrate and the string-like member does not slip.

  In the sanitary napkin of the present invention, bulging portions may be provided at both ends of the string-like member.

  With such a configuration, the user can easily hold the string-like member, and the bulging portion prevents the string-like member from entering the bag-like member or the bag portion.

FIG. 1B is a back view showing the configuration of the sanitary napkin of the first embodiment. 2A to 2D are perspective views showing a change in shape during disposal of the sanitary napkin according to the first embodiment.

  As shown in FIGS. 1A to 1B, the sanitary napkin 100 according to the present embodiment is provided on the surface material 1, the back material 2, the liquid absorber 3 sandwiched between these surfaces, and the back material 2. A continuous bag-shaped member (hereinafter referred to as a bag-shaped member) 11 and a string (string-shaped member) 12 passed through the bag-shaped member 11 are configured.

  The surface material 1 is formed in an elongated shape in which a front end portion F and a rear end portion R are formed in an arc shape, and a portion connecting the front end portion F and the rear end portion R is substantially linear. Here, the front end F means a side positioned on the front surface of the human body when the user uses the sanitary napkin 100, and the rear end R means the human body when the user uses the sanitary napkin 100. Means the side located on the back of In addition, the meanings of the front end portion F and the rear end portion R are similarly used in the back material 2, the main body portion 10, the bag-like member 11, and the like which will be described later. The surface material 1 is provided with a groove 4 in order to prevent the discharged body fluid from flowing out of the sanitary napkin 100. The surface material 1 is composed of a liquid-permeable sheet. Here, the liquid permeable sheet may be provided with a number of holes or embossed so that the discharged body fluid can permeate quickly. Moreover, as a material of the said liquid-permeable sheet, if it is a material which permeate | transmits the discharged body fluid, a well-known thing can be used without a restriction | limiting in particular. For example, a nonwoven fabric, a porous plastic film, etc. can be used. However, the structure of the surface material 1 shown above is an example, and the present invention is not limited to this. For example, the shape of the surface material 1, the presence / absence of grooves, the shape of the grooves, and the like are not limited to those described above.

  The back material 2 is formed in a shape that substantially overlaps the surface material 1. That is, the back material 2 is formed in an elongated shape in which a front end portion F and a rear end portion R are formed in an arc shape, and a portion connecting the front end portion F and the rear end portion R is substantially linear. An adhesive surface 5 is formed on the back material 2. The pressure-sensitive adhesive surface 5 is formed, for example, by applying a hot melt adhesive. The adhesive surface 5 is covered with a release paper (not shown). The back material 2 is composed of a liquid-impermeable sheet. Here, as the material of the liquid-impermeable sheet, a known material can be used without particular limitation as long as it does not transmit the discharged body fluid. For example, a waterproof nonwoven fabric, a plastic film made of polyethylene, a composite material of a nonwoven fabric and a plastic film, or the like can be used. However, the structure of the back surface material 2 shown above is an example, and is not limited to this. For example, the shape of the back material 2 and the arrangement of the adhesive surface 5 are not limited to those described above.

  The liquid absorber 3 has a bowl-like shape with a medium depression. The liquid absorber 3 is interposed so as to be sandwiched between the surface material 1 and the back material 2. Here, as a method of interposing the liquid absorber 3 between the surface material 1 and the back material 2, for example, after the liquid absorber 3 is sandwiched between the surface material 1 and the back material 2, the surface material 1 For example, a method of bonding the outer edge of the back surface material 2 with a hot melt adhesive can be used. Here, as shown in FIGS. 1A (b) and 1 (c), the sanitary napkin main body has a portion where the liquid absorber 3 is interposed between the front surface material 1 and the back surface material 2. Part (hereinafter referred to as main body part) 10. Moreover, as a material of the liquid absorber 3, a well-known thing can be used without a restriction | limiting especially if it is a material which absorbs the discharged | emitted body fluid. For example, a water absorbent fiber, a mixture of a water absorbent fiber and a water absorbent polymer, or the like can be used. Here, when the water-absorbing polymer is mixed with the water-absorbing fiber or the like, the body fluid is absorbed by the water-absorbing fiber while the body fluid is held by the water-absorbing polymer. However, the configuration of the liquid absorber 3 described above is an example, and the present invention is not limited to this. The shape of the liquid absorber 3 is not limited to the above, and may be formed in a rectangular shape, for example.

  The bag-like member 11 is attached so as to substantially follow the outer peripheral portion of the back material 2. Here, as shown in FIGS. 1A (b) and 1 (c), the bag-like member 11 has a cylindrical shape whose cross-sectional shape is flattened. However, the cross-sectional shape of the bag-like member 11 is not limited to this. That is, it is only necessary to have a cross-sectional shape that allows a string 12 described later to pass through the internal space. The bag-like member 11 is formed such that a part thereof protrudes from the surface material 1 and the back surface material 2 (an overhanging portion 11 a) in plan view so that the main body portion 10 is easily raised and collapsed. The overhanging portion 11 a is located from the end of the arcuate portion of the rear end portion R of the main body portion 10 to the central portion in the longitudinal direction. That is, the overhanging portion 11 a is located closer to the rear end R than the central portion in the longitudinal direction of the main body portion 10 in order to facilitate the shape change of the sanitary napkin 100.

  In addition, the bag-shaped member 11 is formed in an arc shape that curves along the arc-shaped portion of the main body portion 10, and the opening portion is formed so as to face the center portion in the short direction of the front end portion F of the bag-shaped member 11. 11b is provided. Here, the reason why the openings 11b are provided so as to face each other is to make it easy to make a knot with a string 12 described later. In the present embodiment, the opening 11b is provided at the front end F of the bag-like member 11, but other parts, for example, the rear end R of the bag-like member 11 or the center of the bag-like member 11 in the longitudinal direction. It may be provided on the left or right side of the part.

  And the bag-shaped member 11 is comprised with a liquid-impermeable sheet. Here, as the material of the liquid-impermeable sheet, a known material can be used without particular limitation as long as it does not transmit the discharged body fluid. For example, a waterproof nonwoven fabric, a plastic film made of polyethylene, a composite material of a nonwoven fabric and a plastic film, or the like can be used. As described above, when the bag-like member 11 is formed of a liquid-impermeable sheet, the discharged body fluid does not penetrate into the bag-like member 11 and the slip of the string 12 described later does not deteriorate.

  Moreover, as a method of attaching the bag-shaped member 11 to the back surface material 2, for example, a tubular liquid-impervious sheet is curved in an arc shape along the arc-shaped portion of the main body portion 10, and the front end portion F of the main body portion 10 is short. There is a method in which after forming the opening 11b at the center in the hand direction, it is attached to the back material 2 of the main body 10 using a hot melt adhesive. As another method, the strip-shaped liquid-impervious sheet is folded in half in the longitudinal direction, curved so that the end portions in the longitudinal direction do not stick together, and then, the dissociated portion in the short direction is folded in half. A method of sewing the back surface material 2 of the sanitary napkin can also be used.

  The string 12 is passed through the bag-like member 11. As shown in FIGS. 1A (b) and 1 (c), the string 12 has a circular cross section. Here, in order to reduce irritation | stimulation to a user's skin, the string 12 can also make the cross-sectional shape flat, or can comprise it using a flexible material. Moreover, both ends of the string 12 are taken out of the bag-like member 11 from the opposed openings 11b of the bag-like member 11, as shown in FIG. 1B. And the knot is formed so that both the opposite ends (one end and the other end) of this string 12 may be wrapped. Here, in the sanitary napkin 100 of the present embodiment, a knot is formed in advance, but the knot is not formed before use, and the user forms a knot when discarding after use. It is good also as a structure which can be performed. Moreover, the tag 13 as a bulging part is attached to the both ends of the string 12, respectively. By attaching the tag 13, the user can easily hold the string 12 and the string 12 is prevented from entering the bag-shaped member 11. Here, in order to prevent the string 12 from entering the bag-like member 11, other configurations may be employed. For example, a knot may be formed at each end of the string 12.

  A method of using the sanitary napkin 100 configured as described above will be briefly described.
