できるようにする。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable diaper that can be worn by an adult or an infant who cannot go to the toilet and cannot excrete, and that can be stored with human waste and discarded together with the human waste. [0002] Conventionally, disposable diapers have been used in such a manner that a water-absorbing sheet is applied to the body. If you excrete in this state, especially the stool will adhere to the buttocks,
People who used it often felt uncomfortable. Also,
In the case of loose stool, the user often feels uncomfortable because the stool adheres to the buttocks and leaks from the back and crotch until the water-absorbing sheet absorbs water sufficiently. [0003] The problem to be solved by the present invention is to solve these problems of the prior art, and excreted stool and urine hardly adhere to the buttocks and can be used comfortably. Another object of the present invention is to provide a disposable diaper that absorbs loose stool and urine efficiently, makes it difficult for the stool and urine to adhere to the buttocks, prevents leakage from the back and crotch, and can be used comfortably. Means for solving the above problems are as follows: 1) A closed bag space is formed by an upper sheet and a lower sheet, and all or a part of the inner surface of the bag space is formed. The upper sheet is opened at the center, and the periphery of the opening is
An elastic body to be contracted is provided on the upper sheet, and the upper sheet and the lower
To widen the passage for human waste between the two sheets
And waterproof the bag space side of the upper sheet and the outside of the lower sheet
In addition, the upper part of the upper sheet is
There is a disposable diaper provided with a water zone so as to be water-absorbing, so that human waste can be stored in a bag space. According to the present invention, human waste excreted by humans is accommodated in the bag space through the opening. Since the buttocks are covered with the upper sheet except for the opening, the stool stored in the bag space rarely adheres to the buttocks even if it adheres to the upper sheet. In addition, since loose stools and urine are stored in a bag-shaped space, they can be received so as not to leak even if they flow to the back or crotch, and spread between the upper sheet and the lower sheet. Since water is absorbed by the area, it can be efficiently absorbed. Since the elastic body that contracts along the periphery of the opening is provided, the opening is contracted so that the periphery of the opening is stretched so as to be in close contact with the buttocks, thereby reliably guiding the human waste to the bag space. Since there is provided a sheet having a waterproof below the bag space side and a lower sheet of the upper sheet, ooze moisture absorbed upward sheet outside touching the buttocks waterproof sheet of the bag space side of the upper sheet In addition, loose stools and urine discharged into the bag space are easily spread between the upper sheet and the lower sheet, and moisture absorbed outside is leaked by the waterproof sheet outside the lower sheet. I try not to. DESCRIPTION OF THE PREFERRED EMBODIMENTS The upper sheet and the lower sheet having a water absorbing property include a polymer absorbent material, absorbent cotton and a fiber pulp having a multi-layer structure, and those having a high water absorbing property are preferred. . The elastic body includes rubber, thread rubber, and the like, and a thread-like or string-like thing that is attached so as to be sewn is preferable. An embodiment of the present invention will be specifically described with reference to the drawings. The embodiment shown in FIGS. 1 to 5 is an example of a disposable diaper in which an elastic body is provided along the periphery of the opening, and a waterproof sheet is provided on the bag space side of the upper sheet and the outside of the lower sheet. FIG. 1 is an explanatory view showing a state in which the thread rubber of the disposable diaper of the embodiment is stretched to make the upper sheet and the lower sheet flat. FIG. 2 is an explanatory diagram of the disposable diaper of the embodiment. FIG. 3 is a sectional view taken along line AA of FIG. 4 and 5 are explanatory views showing a state in which the disposable diaper of the embodiment is used. In the drawing, 1 is a disposable diaper, 2 is an upper sheet, 2a is an opening, 2b is thread rubber, 2c is a waterproof sheet portion, 2d is an absorption band, 2e is a surface nonwoven fabric, 3 is a lower sheet, 3a is a waterproof sheet portion, 3b is an absorption band, 3c is a surface nonwoven fabric, 4 is a bag space, 5 is an adhesive part, 10 is excrement, 11
Is a diaper cover, and h is a human hip. In the disposable diaper 1 of the embodiment, a sheet having a rectangular shape and water absorbability is used as the upper sheet 2 and the lower sheet 3. The upper sheet 2 and the lower sheet 3 are surface nonwoven fabrics 2e and 3c having good water permeability and texture, respectively, and a waterproof sheet part 2 having waterproof property.
The water absorption zones 2d and 3b having a high water absorption are provided between c and 3a. The peripheral portions of the upper sheet 2 and the lower sheet 3 are joined together as an adhesive portion 5 to form a bag space 4. Next, as shown in FIGS. 1 and 2, the upper sheet 2 is provided with an opening 2 a that opens a part of the bag space 4. In the upper sheet 2 around the periphery of the opening 2a, a thread rubber 2b is provided so as to be sewn into the upper sheet 2 so as to surround the opening 2a as shown in FIG. 1 so that the periphery of the opening 2a contracts. To In the disposable diaper 1 of the embodiment, the thread rubber 2b is overlapped on a side portion of the opening 2a so that a strong contraction force is applied. Also, the waterproof sheet portions 2c and 3a are located on the bag space side of the upper sheet 2 and outside the lower sheet 3. In order to use the disposable diaper 1 of the present embodiment, the diaper cover 11 is used so that the rim of the opening 2a is positioned so as to cover around the anus of the buttocks h as shown in FIGS. Fixed to. Since the rubber thread 2b to be contracted is attached to the periphery of the opening 2a, the upper sheet 2 is pulled and stretched without curving to the lower sheet 3 curving along the inside of the diaper cover 11. Try to. Therefore, the upper sheet 2 comes into close contact with the buttocks h. In addition, the bag space 4 is thereby enlarged. When a person excretes in this state, the stool and urine pass through the opening 2.
a and is stored in the large bag space 4. Upper sheet 2
The stool and urine contained in the bag space 4 between the upper sheet 2 and the lower sheet 3 may move upward even if
, It is difficult to re-attach to the buttocks h. Also, since the excrement is discharged into the bag space 4, the stool and urine do not immediately adhere to the buttocks h and do not leak from the back and crotch parts as in the conventional case, so that the user can use it well. Can be very comfortable. Also, when loose stools and urine are discharged and loose stools and urine are stored in the bag space 4 from the opening 2a,
The provision of the bag space 4 allows absorption over a wider surface, as compared with the related art that is attached to the buttocks h in close contact. Therefore, it can be efficiently absorbed, so that it is less likely to re-adhere to the buttocks h in a state of being accumulated before being absorbed, and that side leakage is further less likely to occur. A waterproof sheet portion 2 is provided on the lower surface of the upper sheet 2.
Since c is provided, it is difficult to reattach to the buttocks h. Therefore, the user can use it comfortably and is very comfortable.
Also, even if loose stool or urine adheres to the buttocks, the upper sheet of the upper sheet 2 is absorbed by the upper sheet 2 if it is in contact with the upper sheet 2 because the upper sheet has a water-absorbing surface. It is more comfortable because it does not stay attached.
Also, since the waterproof sheet portion 2c is provided on the bag space side of the upper sheet 2 and outside the lower sheet 3, the upper sheet 2
So as not to re-adhere to the buttocks h and to re-appear to the outside of the lower sheet 3 and adhere to the diaper cover 11. After excrement is discharged, remove it from your body and replace it with a new one. The disposable diaper 1 is discarded.
Thus, if the disposable diaper 1 of the present embodiment is used,
It can be used very comfortably without soiling clothes or bedding due to leakage. FIGS. 6 to 10 show another example of the disposable diaper according to the embodiment. As shown in FIGS. 6 to 8, the length position and number of the rubber thread 2 b may be changed so as to change the state in which the periphery of the opening is contracted. FIG. 9 shows another example of the disposable diaper of the embodiment. In this way, the diaper cover 11 and the disposable diaper 1 may be configured to be integrated. FIG. 10 shows another example of the disposable diaper of the embodiment. In the figure, 6a is a stool opening, and 6b is a urine opening. In another example of the embodiment shown in FIG. 10, a stool opening 6a and a urine opening 6b are provided so that the opening of the upper sheet 2 into the bag space 4 is roughly divided into stool and urine. As described above, the shape of the opening may be changed according to ease of use and purpose. According to the present invention, excreted stool and urine hardly adhere to the body and can be used comfortably, and loose stool and urine can be efficiently absorbed and hardly adhere to the body. It can be used comfortably without leaking from the crotch. It is provided with the elastic body contracts along the periphery of the opening, reliably to allow excretion in the bag space and can be more pleasant to use as it absorbs more efficiently so as to widen the bag space To do.
