Furthermore, in that case, instead of the guard 17 described above, the lower outer edge portion of the second inner cover 122 (the portion where the second inner cover 122 is in contact with the lower outer edge portion of the second water absorbent 123). It is desirable to provide a gather or frill-like guard extending from the second inner cover 122 to the side facing the human body along the second side cover 122.

The surfaces of the first tape fastener 133, the second tape fastener 143, and the third tape fastener 161 are raised like a hook, and the surfaces of the first tape panel 15 and the second tape panel 162 are looped. The surface of the first tape fastener 133, the second tape fastener 143, or the third tape fastener 161 is raised in a loop shape so that the first tape panel 15 or the second tape fastener The surface of the tape panel 162 may be raised like a hook.

Further, the side fixing mechanism or the lower fixing mechanism described above may be a fixing mechanism other than a hook-and-loop fastener. For example, it is also conceivable to fasten the front main body 11 and the rear main body 12 with an adhesive tape.

Each component of the diaper 1 is made of paper or non-woven fabric as a main raw material, for example, but the diaper 1 is not necessarily disposable, so it is made of cloth, synthetic resin, etc. Also good.

Moreover, the 1st water absorption body 113 or the 2nd water absorption body 123 may be provided with the unilateral liquid-permeable sheet | seat which covers those main bodies. With such a configuration, it is difficult for the liquid absorbed in the main body of the first water absorbent body 113 or the second water absorbent body 123 to leak to the outside, and the liquid is firmly placed inside them. It can be stored.

(Second Embodiment)
The second embodiment, which is another specific example of the present invention, will be described below with reference to the drawings. In addition, the diaper cover 2 concerning this embodiment applies the present invention to the diaper cover which can be used repeatedly.

The configuration of the diaper cover 2 is common to the configuration of the diaper 1 according to the first embodiment in many respects. Therefore, in the following description, the diaper cover 2 will be described focusing on differences from the diaper 1. Moreover, in the figure, the same code | symbol is attached | subjected about the thing corresponding to the structural part with which the diaper 1 is equipped among the structural parts with which the diaper cover 2 is equipped.

FIG. 5 is a plan view showing the side of the diaper cover 2 according to the present embodiment that faces the human body. FIG. 6 is a plan view showing the side of the diaper cover 2 according to the present embodiment that does not face the human body.

First of all, unlike the diaper 1, the diaper cover 2 does not have a water absorbing body. That is, the front main body portion 11 of the diaper cover 2 does not include the first water absorbent body 113 and is constituted by, for example, the first outer cover 111 and the first inner cover 112. Similarly, the rear main body portion 12 of the diaper cover 2 does not include the second water absorbing body 123, and is constituted by, for example, the second outer cover 121 and the second inner cover 122.

In addition, the front side main body part 11 and the rear side main body part 12 are not limited to the structure by these two layers, For example, you may be comprised by the cover of 1 layer and may be comprised by the cover of 3 layers or more.

As described above, the front main body portion 11 and the rear main body portion 12 of the diaper cover 2 are not provided with the water absorbing body 113 and the water absorbing body 123, respectively. No guard (including guard 17) is provided on the outer edge of 113 and water absorber 123.

Further, the material of the front main body portion 11 and the rear main body portion 12 of the diaper cover 2 is a material having durability that can withstand repeated use and washing, such as cotton cloth, polyester cloth, wool cloth, and combinations thereof.

Further, in the diaper cover 2, the right protruding portion 131 and the right extending portion 132 in the diaper 1 are integrally configured as the right protruding portion 134. Therefore, the first tape fastener 133 is directly attached to the inner side surface of the right protruding portion 134 protruding rightward from the rear main body portion 12 by sewing or the like. Similarly, in the diaper cover 2, the left protrusion 141 and the left extension 142 in the diaper 1 are integrally configured as a left protrusion 144. Therefore, the second tape fastener 143 is directly attached to the inner surface of the left protruding portion 144 protruding leftward from the rear main body portion 12 by sewing or the like.

The reason why the first tape fastener 133 and the second tape fastener 143 are directly attached to the right protrusion 134 and the left protrusion 144 as described above in the diaper cover 2 is as follows. This is because, in general, high durability is easily obtained as compared with the case where a similar configuration is employed. Therefore, if sufficient durability can be obtained, a configuration in which the right extending portion 132 is attached to the right protruding portion 131 and the left extending portion 142 is attached to the left protruding portion 141 in the same manner as the diaper 1 in the diaper cover 2 is adopted. May be.

Also, a fourth tape fastener 124 is attached by sewing or the like around the center of the inner surface of the rear main body 12 of the diaper cover 2. The 4th tape fastener 124 is provided in order to fix the water absorption sheet 3 demonstrated below to the rear side main-body part 12. FIG.

The diaper cover 2 is used together with a disposable water absorbent sheet 3 that serves as a diaper main body. That is, the diaper cover 2 covers the human body with the water absorbent sheet 3 sandwiched between the human body.

FIG. 7 is a plan view showing the side of the water absorbent sheet 3 according to this embodiment that faces the human body. 8 is a cross-sectional view taken along the line AA in FIG. 7 (FIG. 8A) and a cross-sectional view taken along the line BB in FIG. 7 (FIG. 8B).

The water absorbent sheet 3 includes an outer cover 311 having liquid impermeability, an inner cover 312 having liquid penetrability, and a water absorber 313 disposed between the outer cover 311 and the inner cover 312.

The outer cover 311 has liquid impermeability, but is provided with a lot of very small holes so that steam can be discharged from the water absorbent body 313 to the outside. As the material of the outer cover 311, for example, paper or nonwoven fabric can be used.

The inner cover 312 has a liquid permeability, but uses a material having a lower hydrophilicity than the water absorbent body 313 so as to give a relatively dry feel when worn. The inner cover 312 is desirably soft so as not to irritate the human body. As the material of the inner cover 312, for example, paper or nonwoven fabric can be used.

The water-absorbing body 313 is constituted by sandwiching a large number of particles made of a material having a very high water absorption such as a water-absorbing polymer between paper or a nonwoven fabric having a high water absorption. With such a configuration, the water absorbing body 313 has a function of absorbing and storing the liquid discharged from the human body.

A gathered or frilled inner guard 314 is provided on the outer edge of the water absorbing body 313 so as to extend to the side facing the human body. Further, a gathered or frilled outer guard 315 is provided on the outer edge of the water absorbent sheet 3 so as to extend to the side facing the human body. When the water absorbent body 313 is worn on the human body by the diaper cover 2, the inner guard 314 and the outer guard 315 are pressed against the human body side with weak elastic force, so that the liquid absorbed by the water absorbent body 313 and the water absorbent body 313 It becomes possible to prevent leakage of excreta that could not be absorbed.

The inner guard 314 and the outer guard 315 are made of, for example, paper or non-woven fabric as a main raw material, and have a large number of wrinkles in the direction toward the human body when not worn, and when worn, the wrinkles extend to the human body. Prevents liquid leakage while fitting.

The water-absorbing sheet 3 is shaped like a bowl when viewed from above, as shown in FIG. 7, for example. In FIG. 7, the upper part of the water absorbent sheet 3 is disposed on the abdomen side of the human body when worn, and the lower part is disposed on the buttocks side of the human body when worn. That is, the upper side (the side where the area is small) in FIG. 7 of the water absorbent sheet 3 mainly absorbs urine, and the lower side (the side where the area is wide) mainly captures stool. Therefore, as shown in FIG. 8 (a), the upper side of the water absorbent sheet 3 in FIG. 7 is formed with a uniform thickness of the water absorbent body 313, and the lower side is formed with a thin water absorbent body 313 in the center. Yes. Therefore, the upper portion of the water absorbent sheet 3 in FIG. 7 has a higher water absorption capacity per unit area than the lower portion, and is suitable for urine absorption, and the lower portion has a larger capacity than the upper portion in the central portion. A recess is formed, which is suitable for capturing stool.

FIG. 9 is a plan view of the state before the diaper cover 2 and the water absorbing sheet 3 are attached to the human body, as viewed from the side facing the human body. First, as in the case of the diaper 1, the diaper cover 2 is assembled in a state where only the first tape fastener 133 of the rear main body portion 12 is fixed to the right region of the first tape panel 15 of the front main body portion 11. Thereafter, the fourth tape fastener 124 is fixed to an appropriate position of the rear main body portion 12 by pressing the central portion of the outer surface of the water absorbent sheet 3 on the fourth tape fastener 124 of the rear main body portion 12. .

In addition, when the outer side surface of the water absorbing sheet 3 is made of, for example, a nonwoven fabric, the hook-shaped protrusion of the fourth tape fastener 124 is formed on the outer side surface of the water absorbing sheet 3 without providing a tape panel. It is entangled with the outer surface, and the position can be fixed. When the material on the outer surface of the water absorbent sheet 3 is a material that does not entangle with the fourth tape fastener 124, a tape panel is provided on the outer surface of the water absorbent sheet 3, and can be fixed to the fourth tape fastener 124. do it.

When the diaper cover 2 and the water absorbent sheet 3 are set in the state shown in FIG. 9 as described above, the subsequent usage is the same as that described above with respect to the diaper 1.

According to the diaper cover 2 and the water absorbent sheet 3 according to the present embodiment, the same effect as that described in the diaper 1 according to the first embodiment, that is, the ease of attaching and detaching the diaper to the human body can be obtained.

In addition, according to the diaper cover 2 and the water absorbent sheet 3 according to the present embodiment, the disposable part is only the water absorbent sheet 3, and compared with a conventional disposable disposable diaper, the cost is reduced, resources are saved, and garbage is reduced. Is realized.

Moreover, according to the diaper cover 2 and the water absorption sheet 3 concerning this embodiment, since the size of the water absorption sheet 3 which should be covered with a diaper cover is small compared with the conventional paper diaper, the area | region covered with a diaper cover can be narrowed. . Therefore, it is possible to realize a diaper cover that is more stylish and highly designed.

In addition, in the diaper cover 2 according to the present embodiment, as with the conventional diaper cover, for example, the diaper cover 2 having different materials and structures having different breathability and heat retaining properties depending on the season can be used to make the user comfortable. Can increase the sex. Furthermore, in the diaper cover 2 according to the present embodiment, it is possible to select or use a design according to the taste of the user, his / her mother, etc., as in the conventional diaper cover.

The second embodiment described above can also be variously modified within the scope of the technical idea of the present invention.

For example, as described in the first embodiment, the side fixing mechanism is provided only in one of the right side connecting part and the left side connecting part, and the front main body part 11 and the rear main body part 12 are integrated from the beginning as the other. And may be continuous in that part.

In addition, although a plurality of guards are provided in the direction facing the human body from the water absorbent sheet 3, the number and shape of these can be arbitrarily changed. In addition, although it is desirable that these guards are provided to prevent leakage of excrement, the guards may not be provided if there is no particular problem in use.

Further, as described in the first embodiment, instead of the lower rear extending portion, a lower front extending portion extending from the lower side of the rear main body portion 12 is provided, and the lower front extending portion is below the crotch in the human body. It is good also as what is fixed on the front side main-body part 11, ie, the 1st outer side cover 111, in either of the range from a lower abdominal part to a crotch part.

In that case, a tape fastener corresponding to the third tape fastener 161 is provided on a surface of the lower front extending portion facing the human body, and a tape panel corresponding to the second tape panel 162 is provided on the first outer cover 111. Are provided, and these tape fastener and tape panel constitute the lower connecting portion.

The surfaces of the first tape fastener 133, the second tape fastener 143, and the third tape fastener 161 are raised like a hook, and the surfaces of the first tape panel 15 and the second tape panel 162 are looped. The surface of the first tape fastener 133, the second tape fastener 143, or the third tape fastener 161 is raised in a loop shape so that the first tape panel 15 or the second tape fastener Similarly to the first embodiment, the surface of the tape panel 162 may be raised like a hook.

Further, the side fixing mechanism or the lower fixing mechanism described above may be a fixing mechanism other than a hook-and-loop fastener.

Further, the water absorbing body 313 may include a one-side liquid-permeable sheet that covers the main body. If it is set as such a structure, it will not occur easily that the liquid absorbed by the main body of the water absorption body 313 leaks outside, and it becomes possible to store the said liquid firmly in those inside.

Moreover, the shape of the water absorbing sheet 3 can be changed variously. For example, the shape seen from above is not limited to a saddle shape, and may be a rectangle or an ellipse.

Moreover, in 2nd Embodiment mentioned above, although demonstrated as what employ | adopted the structure which fixes the water absorbing sheet 3 with respect to the 4th tape fastener 124 provided in the rear side main-body part 12, the diaper of the water absorbing sheet 3 was employ | adopted. The method of fixing to the cover 2 is not limited thereto. For example, the outer cover 311 is extended on both sides of the water absorbent sheet 3, and an adhesive portion is provided on the outer side of the extended outer cover 311 (the side facing the diaper cover 2). The structure which fixes the water absorption sheet 3 with respect to the diaper cover 2 may be employ | adopted by sticking to the inner surface of the diaper cover 2 (for example, the rear side main-body part 12).

Furthermore, if the water absorbent sheet 3 does not shift during wearing due to friction between the diaper cover 2 and the water absorbent sheet 3 when the water absorbent sheet 3 is pressed against the human body by the diaper cover 2 and friction between the water absorbent sheet 3 and the human body, It is not always necessary to fix the water absorbent sheet 3 to the diaper cover 2. In that case, the rear main body 12 may not include the fourth tape fastener 124.

When it is not necessary to fix the water absorbent sheet 3 to the diaper cover 2, the diaper cover 2 and the water absorbent sheet 3 are worn on the human body, for example, as follows. First, the diaper cover 2 is assembled in a state where only the first tape fastener 133 of the rear main body 12 is fixed to the right region of the first tape panel 15 of the front main body 11.

Subsequently, the diaper cover 2 is applied from the right side of the human body so that the front main body portion 11 and the rear main body portion 12 of the diaper cover 2 thus assembled cover the lower abdomen and the buttocks of the human body, respectively. In this state, the second tape fastener 143 is fixed to the left region of the first tape panel 15 while pulling the left protrusion 144 from the left rear of the human body to the left front of the human body. As a result, the front main body 11 is hung on the front side of the body, and the rear main body 12 is hung on the rear side of the body.

Next, the water absorbent sheet 3 is pressed from the buttocks side to an appropriate position on the human body, and the lower part of the rear body part 12 is immediately pushed downward from the front body part 11 while pushing the lower part to the front side under the crotch. The lower rear extending portion is pulled up through the crotch from the front side to the rear side, and the third tape fastener 161 is pressed against the second tape panel 162 and fixed.

By the way, it is desirable from the viewpoint of preventing the water absorbing sheet 3 to adhere appropriately to the human body. In particular, in a mode in which the water absorbent sheet 3 is not fixed to the diaper cover 2, there is a high need for preventing slippage. Therefore, a material having low adhesiveness to the human body may be used in a portion of the water absorbent sheet 3 that contacts the human body.

According to the diaper or the diaper sheet and the water absorbent sheet according to the present invention, not only infants but also elderly people and sick people can easily attach diapers.
