  In the following description, extending the crotch member from the back body toward the front body may be referred to as “pulling the crotch member forward”.

<First Embodiment>
A sanitary short 1 according to the present invention will be described with reference to FIGS. FIG. 1 is a perspective view of a shorts body 1A, and FIG. 2 is a developed view of the front body 2 and the back body 3 of the shorts body 1A as viewed from the inside (side in contact with the wearer) of the shorts body 1A. In addition, when referring to front, back, left and right, it means the direction seen from the wearer. Moreover, the width direction of 1 A of shorts main bodies says the direction parallel to a wearer's left-right direction.

  In the sanitary shorts 1 of the present embodiment, a shorts body 1A is formed of a front body 2, a back body 3, and a crotch member 4 positioned therebetween. Specifically, the shorts body 1A includes an inner end 2a of the front body 2, an inner end 3b of the rear body 3, and a front end extending in the width direction of the sanitary shorts 1 on the front body 2 side of the crotch member 4. Part 4a and rear end part 4b extending in the width direction of sanitary shorts 1 on the back body 3 side are joined to each other by stitching, and the front body 2 and the sewn part of the crotch member 4 are The joint portions 6a and 6b are configured. Furthermore, the grip part 7 is connected to the inner side of the shorts main body 1A through a connection part 8 extending over the entire length in the width direction of the inner end part 2a of the front body 2 along the joint part 6a. Specifically, the gripping part 7 has a base end part 16 and a free end part 17, and the connecting part 8 (base end part 16) is overlapped with the joint part 6 a and is sewn, so that the shorts body 1 A It is connected. In addition, the junction part 6a is symmetrical about the vertical center line M (refer FIG. 2) which bisects the width direction dimension of 1 A of shorts main bodies.

  Both the front body 2 and the back body 3 are formed of a woven cloth, and the crotch member 4 is formed by superposing an outer cloth 10 made of a woven cloth on the outer side of the shorts body 1A and a waterproof cloth 11 located on the inner side. It is formed by stitching. The crotch member 4 is attached with a sanitary napkin 5 indicated by a virtual line.

  The woven fabrics of the front body 2, the back body 3, and the outer cloth 10 of the crotch member 4 are stretchable from the viewpoint that they have a good touch and high air permeability and moisture absorption, and further improve the fit with the wearer's body. It is preferable to have. In the present embodiment, a woven fabric made of 66% stretchable nylon fiber, 24% cotton, and 10% polyurethane fiber is used as the woven fabric constituting the front body 2, the back body 3, and the outer fabric 10.

  The waterproof cloth 11 can be made of an air permeable and liquid impermeable material. In this embodiment, a material obtained by laminating polyurethane on a polyester woven fabric is used. The elongation coefficient defined by the value obtained by dividing the load at the time of 10% of the material constituting the waterproof cloth 11 and the woven cloth constituting the front body 2 and the like by the elongation ratio is 25 N and 6.7 N, respectively. 11 is smaller in elongation. The load at the time of 10% elongation is measured with an autograph AG-1kNI manufactured by Shimadzu Corporation using a test piece having a width of 25 mm with a chuck interval of 100 mm and a pulling speed of 100 mm / min. The elongation coefficient is calculated as 2.5 N / 0.1 = 25 N when the load at 10% elongation is 2.5 N / 25 mm, for example.

A waist opening W is formed at the upper part of the shorts body 1A by a waist opening forming edge 12 constituted by the upper ends of the front body 2 and the back body 3, and the front body 2, the back body 3 and the crotch member are formed on the left and right sides. A pair of left and right leg-hole openings L is formed by leg opening forming edges 14 formed by four side edges. Further, a waist elastic member 13 extends along the waist opening forming edge 12, and a pair of left and right leg elastic members 15 extend along the front body 2 and the crotch member 4 of the leg opening forming edge 14, respectively. Attached and extended. Due to the elastic contraction of the leg elastic member 15, the leg opening L fits the wearer's leg, and the sanitary napkin 5 is pulled upward toward the shorts body 1A to fit the wearer.
The waist elastic member 13 and the leg elastic member 15 are made of string-like material having rubber elasticity, and are sewn to the waist opening forming edge 12 and the leg opening forming edge 14, respectively. In addition, the elastic members 13 and 15 can also use elastic nonwoven fabric.

  The grip part 7 for extending the crotch member 4 from the back body 3 to the front body 2 is formed separately from the front and back bodies 2 and 3, has a substantially semicircular shape, and has a slightly curved base end. A connecting portion 8 extending on 16 is overlapped and stitched to the joint portion 6a and connected to the front body 2. The base end portion 16 may be formed in a linear shape. Further, both side portions of the connecting portion 8 are fixed to the leg-around elastic member 15 by sewing.

  The gripping part 7 is formed by stitching the same material as that of the waterproof cloth 11 on the woven fabric of the same material as that of the front body 2. Thus, by including the material of the waterproof cloth 11 having a lower stretchability than the front body 2 and more specifically lower stretchability, the gripping portion 7 has a lower stretchability than the front body 2, and more specifically, a slight stretchability. It has become. However, the gripping portion 7 may be substantially non-stretchable. Further, the connecting portion 8 is formed by folding and sewing the proximal end portion 16 of the gripping portion 7, thereby increasing the thickness, and including the waterproof cloth 11, so that it has higher rigidity than the front body 2. It has become.

  Thus, by making the gripping part 7 slightly stretchable or substantially non-stretchable, when the gripping part 7 is pulled by hand, the gripping part 7 is deformed and the force transmitted to the crotch member 4 is lost. Can be suppressed. In order to obtain the slightly stretchable gripping part 7, it is preferable to use a material having an elongation coefficient of 20N (2.0N / 0.1) or more at 10% elongation.

The gripping part 7 is symmetric with respect to the vertical center line M of the shorts body 1A. Thereby, when the holding part 7 is pulled by hand, the force applied to the crotch member 4 is equalized.
It is preferable that the grip portion 7 has a rounded corner shape so as to be easily held by hand so as not to impair the wearing feeling of the shorts body 1A. Further, it is preferable to attach a reinforcing member such as a woven fabric along the arcuate free end portion 17 of the gripping portion 7 to suppress a loss of force due to deformation of the gripping portion 7 when pulled by hand.

  When the wearer intends to attach the sanitary napkin 5 to the shorts body 1A of the present embodiment, the crotch member 4 is gathered around the leg opening forming edge 14 due to the elastic contraction of the pair of leg elastic members 15. In other words, it is in a wrinkled state. Or it may be in a kinked state depending on the posture of the wearer.

  When the gripping part 7 is pulled forward, the crotch member 4 is stretched, and the wrinkles and kinks caused by the leg-around elastic members 15 are eliminated, and the flat part becomes substantially flat. More specifically, since the joint portion 6a is formed by stitching the front body 2 and the crotch member 4, the connecting portion 8 is thicker and more rigid than the front body 2 and overlaps the joint portion 6a. Thus, it is more rigid than the front body 2. The stretchable crotch member 4 and the leg-hole elastic member 15 causing wrinkles are joined to the overlapping portion of the high-rigidity portions, and both are symmetrical with respect to the vertical center line M of the shorts body 1A. When 7 is pulled forward, the leg-hole elastic member 15 and the crotch member 4 are uniformly stretched, and the crotch member 4 becomes substantially flat.

  If the sanitary napkin 5 is attached to the flat crotch member 4, there will be no gap between the sanitary napkin 5 and the shorts body 1A, and the sanitary napkin 5 will not be attached in a kinked state. The sanitary napkin 5 can be attached to the sanitary shorts 1 in a state that fits properly to the wearer.

  Note that the gripping portion 7 is preferably connected to the inside of the shorts body 1A. In order to attach the sanitary napkin 5 with one hand, an operation of expanding the waist opening W and an operation of pulling the gripping portion 7 are simultaneously performed, and the sanitary napkin 5 is attached to a predetermined position of the crotch member 4 with the other hand. Therefore, it is possible to easily attach the sanitary napkin. Moreover, it is preferable to connect so that the holding | grip part 7 may be extended toward the direction which goes to the front body 2 from the back body 3. FIG. If it is provided in this direction, it is possible to easily perform an operation of holding the grip portion 7 with one hand and pulling it forward.

Second Embodiment
Next, a second embodiment will be described with reference to FIG. FIG. 3 is an exploded view showing the front body 2 and the back body 3 of the shorts body 1A according to the second embodiment separately. This embodiment is different from the first embodiment in the attachment position of the grip portion 7, and the other is common. In the following description, the same reference numerals are used for members common to the first embodiment, and overlapping descriptions are omitted as much as possible.

In the present embodiment, the connecting portion 8 is sewn and connected to the front body 2 away from the joint portion 6a in a direction substantially parallel to the width direction of the shorts body 1A. The length of the connecting portion 8 in the width direction is substantially the same as the minimum width of the crotch member 4.
As long as the connecting portion 8 is located along the joining portion 6a, the separation distance of the connecting portion 8 from the joining portion 6a is not particularly limited, and is a position where the gripping portion 7 can be stored inside the front body 2 when worn. It is preferable.

  The connecting portion 8 and the joining portion 6a extend in the width direction of the shorts body 1A, and the rigidity thereof is higher than that of the front body 2 as described above. Therefore, in the front body 2, the virtual region R (shown by a dashed line in FIG. 3) sandwiched between the connecting portion 8 and the joint portion 6 a is as if a stretchable woven fabric is stretched between the two rigid members. It is in the state that was done.

  When the sanitary napkin 5 is attached to the shorts body 1A, when the grip portion 7 is pulled forward, the woven fabric in the region R of the front body 2 is stretched through the connecting portion 8, whereby the joint portion 6a is pulled. In conjunction with this, the entire woven fabric constituting the crotch member 4 and the leg-around elastic member 15 extending to the leg opening forming edge 14 of the crotch member 4 are pulled forward. At this time, since the joint portion 6a and the connecting portion 8 are substantially parallel and both are symmetrical with respect to the longitudinal center line M of the shorts body 1A, the crotch member 4 is pulled uniformly. As a result, the crotch member 4 becomes substantially flat, so that the sanitary napkin 5 can be attached to the shorts body 1A in a state where the sanitary napkin 5 properly contacts the wearer's local area.

As mentioned above, although the sanitary shorts based on this invention were demonstrated based on embodiment, it is not limited to these, It can implement in various changes.
For example, the present invention can also be applied to a type of sanitary shorts in which a sanitary napkin is appropriately brought into contact with a wearer's local area only by elastic contraction of a front body, a crotch member, or the like without using an elastic member around a leg.

  In addition, although the case where the gripping part is formed separately from the sanitary shorts has been described, the gripping part is formed integrally with the crotch member, the gripping part is reinforced with a resin film or the like to make it slightly stretchable, and the inseam It can also be set as the structure which forms a highly rigid connection part by pinching and sewing a resin sheet to the junction part of a member and a front body.

  Furthermore, although the front body, the back body, and the crotch member have been described as being made of a single woven fabric, the front body can be composed of, for example, a plurality of woven fabrics having different elongation rates. Further, the joining method of the front body and the crotch is not limited to stitching, and may be heat fusion or adhesion. The woven fabric constituting the front body or the like is not limited to the embodiment, and other known woven fabrics can be used as a material for sanitary shorts such as a woven fabric made of cotton, polyester fiber, and polyurethane fiber. Alternatively, a nonwoven fabric can be used instead of the woven fabric. A known material can be used for the waterproof cloth. For example, a composite cloth in which polyfluorinated ethylene, polyethylene or the like is laminated on the woven cloth can be used.

  Furthermore, in the above embodiment, the case where the front and back body and the crotch member are formed separately and the crotch member is positioned between the front and back body is described, but the object of the present invention is achieved and the present invention is achieved. Although not illustrated in order to achieve the effects of the invention, as is obvious to those skilled in the art, it is also possible to form the crotch portion corresponding to the position of the crotch member and the front and back bodies with a series of woven fabrics. . In this case, a waterproof sheet is joined to the inner surface of the crotch part, a part of the woven fabric located at the front and rear ends of the crotch part is folded inside the sanitary shorts, and fixed so as to maintain the folded part. It is also possible to provide a gripping portion at or near the folded portion located on the front end portion side of the, or to replace the folded portion at the front end portion with the gripping portion. Since the thickness of the folded portion is larger than the thickness of the other region of the shorts body, the rigidity of the folded portion is higher than that of the other region of the shorts body. In addition, although the sanitary napkin is normally fixed to the crotch part of the sanitary shorts via an adhesive, the fixing may be unintentionally released. Therefore, when the folding portion is provided not only at the front end portion of the crotch portion but also at the rear end portion, a sanitary napkin is positioned between both folding portions of the front and rear end portions, and the sanitary napkin is located at the crotch portion. It is possible to prevent shifting in the front-rear direction.

The perspective view of the sanitary shorts which concern on 1st Embodiment. The expanded view which isolate | separates the front and back bodies of the sanitary shorts of 1st Embodiment mutually. The expanded view which isolate | separates the front and back body of the sanitary shorts of 2nd Embodiment mutually.
