Description

[Technical field]

[0001] The present invention relates to a bag-shaped vinyl sheet for improving the functionality of an excrement absorption pad that can absorb excrement and then be disposed of as is, and particularly to a bag-shaped vinyl sheet for improving the functionality of an excrement absorption pad that can be suitably used for nursing diapers worn by elderly people who are bedridden or nearly bedridden. [Background technology]

[0002] Disposable excrement absorption pads that absorb excrement such as stool and urination, are discarded as is, and then replaced with new ones have been known for some time (see, for example, Patent Document 1).

[0003] Here, the excrement absorption pad described in Patent Document 1 has the overall form of a paper diaper, with the back, crotch and front sections connected, the upper surface covered with a water-permeable sheet and the lower surface covered with a water-absorbent layer with a waterproof sheet, and a pad made of a sheet made of a water-soluble material formed into a bag shape and containing an absorbent material inside is layered on the upper surface of the paper diaper body with the periphery fixed, and the pad is attached to the upper surface of the paper diaper body in a peelable manner. [Patent Document 1] Utility Model Application Publication No. 7-37138 Summary of the Invention [Problem to be solved by the invention]

[0004] The recent rapid aging of society, which is said to be an era of 100-year life spans, has caused various problems. Specifically, the rapid aging of society has led to an increase in the number of elderly people who are bedridden or nearly bedridden due to the onset of symptoms of frailty and sarcopenia, which are conditions that cause muscle atrophy in the legs and hips. It has been said that consuming a lot of meat, which is rich in protein, is effective in preventing or improving the progression of frailty and sarcopenia.

[0005] And, even for elderly people who are bedridden or nearly bedridden as described above, if they have sufficient chewing ability, it is expected that they can suppress or improve the progression of frailty and sarcopenia by chewing and swallowing a large amount of meat and ingesting it into their digestive organs. Of course, it is necessary to not only consume meat, which is the source of muscle, but also vegetables, which contain a lot of water and vitamins and act as plant fiber to improve bowel movements. As a result, the total amount of food that the above-mentioned people chew and swallow is increased accordingly.

[0006] As described above, for elderly people who do not have significant problems with their chewing function and do not need to have nutrition taken in by a gastrostomy or other procedure, the more food and water they take in after chewing and swallowing, the more they will not be digested and absorbed in the body. In other words, after the necessary amount of food taken into the body is digested and absorbed in the digestive organs, the remaining amount will be excreted as feces and urine through excretory organs such as the anus and urethra.

[0007] Therefore, simply wearing the disposable diapers or urinary leakage absorbent pads described above as conventional techniques is not enough to absorb all the feces and urine discharged at once, and the excrement that cannot be absorbed leaks out from the diapers or absorbent pads and adheres to the user's skin.

[0008] When this happens, particularly in the case of elderly people who are bedridden or nearly bedridden, the waste absorption pad is unable to absorb all the waste, and the waste leaks out onto the surrounding area, for example, into the elastic part of the diaper body that corresponds to the waist area and is used to temporarily fasten the waste absorption pad in place each time.

[0009] The elastic part on the back of the diaper body is in a state of being pressed by the weight of the user against the top surface of the bed sheet or the mattress cover, etc. Therefore, especially in the case of elderly people who spend their days in a bedridden or nearly bedridden state, excrement that reaches this elastic part spreads through the area where the user and the elastic part are in close contact due to the so-called capillary phenomenon, and leaks out while adhering to a wide area not only the user's excretion site and its surroundings but also unexpected body parts.

[0010] Disposable diapers, of course, must be changed every day. For people who are bedridden or nearly bedridden, this task must be done by family members or daycare staff such as certified care workers at home, by care home staff such as certified care workers at care homes, and by caregivers such as nurses or certified care workers at hospitals.

[0011] Furthermore, as described above, if a caregiver who is bedridden or nearly bedridden eats more than a certain amount of food, when they excrete that food, the excrement will leak out from the waste absorption pad of the disposable diaper and spread inside the diaper body or spill out from the diaper body, leaving the excrement stuck firmly to the waist, back, inside of the thighs, etc. of the person being cared for, or the excrement will stick to or soak into the bed sheets or futon cover that come into contact with these areas.

[0012] When a caregiver tries to change a disposable diaper in this state, the excrement sticks to the caregiver's hands, and even after spending time washing the hands many times, the smell remains. In addition to this, they have to do extra work such as changing the bed sheets and the mattress cover, and cleaning the bed and the mattress itself, which is very time-consuming. In addition to the daily task of changing disposable diapers, this situation greatly increases the physical and mental burden on the caregiver.

[0013] In addition, if the excrement remains on the skin of the person being cared for until the disposable diaper is changed, not only can the skin of the person being cared for become sore or inflamed, but the fungi that have proliferated in the mouth and are contained in the excrement, which are a type of miscellaneous fungus similar to athlete's foot, can spread to the skin of the person being cared for, causing unbearable itching and itching where the bed sheets or mattress are in contact with the person's body.

[0014] In particular, if the person being cared for has a disease such as colon cancer, the stool may contain blood and be excreted. This can have a huge impact on both the person being cared for and the caregiver, causing an extreme increase in the physical and mental burden for both.

[0015] The problem to be solved above has been explained using the example of elderly people who are bedridden or nearly bedridden, but it goes without saying that the problem is not limited to this and also applies to caregivers of elderly people who are unable to put on or take off disposable diapers by themselves.

[0016] From a similar perspective, for example, even if the user who uses disposable diapers every day is not an elderly person but an infant, the same problem to be solved arises. Specifically, for example, when changing a diaper for the first time after giving birth to a first child, there may be a lot of excrement that leaks out of the disposable diaper. In this case, the mother who changes the disposable diaper and the father who helps with childcare (hereinafter referred to as "mother" or "caregiver" as appropriate) need to remove all the excrement similar to those described above in order to provide the infant with a clean environment, and they must perform the troublesome task of disposing of the excrement each time.

[0017] For mothers who are often said to be suffering from postpartum blues, the daily task of disposing of such troublesome excrement places a considerable physical and mental burden on them. Also, excrement that cannot be absorbed by the excrement absorption pads of disposable diapers adheres to the skin of infants, causing rashes and constant crying due to itching, which causes considerable stress for caregivers trying to soothe them.

[0018] Such stress can, in the worst case, lead to serious problems such as child abandonment and child abuse. Therefore, it is very important to be able to change disposable diapers daily without leaking into the surrounding area.

[0019] Another recent problem is that the number of middle-aged and elderly women who are troubled by urinary incontinence has been increasing in recent years. This is due to the structural differences in the bodily organs of men and women, with the female urethra being shorter than the male urethra. As people age, the urethral sphincter becomes more likely to relax, and many people are using so-called urinary incontinence absorbent pads to deal with urinary incontinence in their daily lives.

[0020] However, wearing a urine leakage absorption pad does not reduce the amount of urine that leaks out, so the discharged urine remains absorbed by the urine leakage absorption pad, and the amount of urine absorbed by the urine leakage absorption pad increases if the pad is worn for a long time. As a result, the wearer becomes concerned about the smell of urine leakage and the dampness of the urine leakage absorption pad itself penetrates to the skin, causing discomfort. This can make it difficult to concentrate on work when out and about, or to enjoy a nice conversation with friends.

[0021] In addition, in line with the recent trend towards the formation of a gender-equal society, opportunities for women to actively enter society and play an active role are rapidly increasing. Here, the problem for women is that heavy menstruation can cause problems for them when they are continuing their social activities. Therefore, it is important to avoid the above-mentioned discharge from leaking out of sanitary products even if the amount of discharge is unexpectedly large, and to dispose of each sanitary product immediately and replace it with a new one, thereby avoiding the trouble of some of the discharge remaining on the body and improving the performance of social activities.

[0022] The object of the present invention is to solve all of the above-mentioned problems at once, and specifically, to provide a bag-shaped vinyl sheet for improving the functionality of excrement (excrement) absorption pads that can absorb excrement and excrement and then be disposed of as is, and that is particularly suitable for use in nursing diapers worn by elderly people who are bedridden or nearly bedridden.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0030] Various embodiments and their modified examples of the bag-shaped vinyl sheet for improving the functionality of an excrement absorption pad according to the present invention will be described below. First, the first embodiment will be described. The bag-shaped vinyl sheet 100 for improving the functionality of an excrement absorption pad according to the first embodiment of the present invention (hereinafter, appropriately referred to as "bag-shaped vinyl sheet 100") is intended to be used as an auxiliary product for so-called nursing diapers worn by people who need help from a caregiver to dispose of excrement such as stool and urination.

[0031] Furthermore, by using the product of the present invention as an auxiliary item, the original functionality of the nursing diaper itself can be enhanced and the number and frequency of changing unusable nursing diapers into new nursing diapers can be significantly reduced, thereby having the effect of significantly reducing the physical and mental burden on the user of the nursing diaper and the physical and mental burden on the caregiver.

[0032] In particular, when the user of the nursing diaper is bedridden or nearly bedridden, the present invention can provide a significantly excellent effect. Therefore, in the following embodiment, the present invention will be described as being used in a disposable nursing diaper for an elderly person who is bedridden or nearly bedridden due to the effects of frailty or sarcopenia.

[0033] However, this embodiment is not necessarily limited to use by care recipients who are bedridden or nearly bedridden, but can also be suitably used by people who must put on and take off nursing diapers themselves or ask a caregiver to do so when dealing with excrement such as stool and urination.

[0034] In addition, in each of the drawings explaining the bag-shaped vinyl sheet for improving the functionality of excrement (discharge) absorption pads according to the embodiments described below, the size of the bag-shaped vinyl sheet of the present invention is drawn to be considerably larger than the size of the excrement absorption pad and the excrement absorption pad, but the dimensional relationship between the two is not limited to such a relationship, and it is of course acceptable for the bag-shaped vinyl sheet to be smaller in size than that shown in the drawings compared to the size of the excrement (discharge) absorption pad.

[0035] In addition, the size of this top opening is drawn to be quite large in relation to the size of the bag-shaped vinyl sheet, but this is merely an example of such a dimensional relationship for the convenience of understanding and explaining the invention, and it goes without saying that the upper opening will be smaller in size in relation to the size of the bag-shaped vinyl sheet depending on the usage form corresponding to each embodiment and its modified example.

[0036] The material of the bag-shaped vinyl sheet in the present invention described above is not necessarily limited to vinyl as stated herein, and other materials may be used as long as the waste material (excreted matter) can be collected inside the bag-shaped vinyl sheet. However, for the convenience of explaining the present invention, the following description will be given assuming that the material is a vinyl sheet.

[0037] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A bag-shaped vinyl sheet for improving the functionality of an excrement absorption pad according to a first embodiment of the present invention (hereinafter referred to as "this embodiment") will be described in detail below with reference to the drawings.

[0038] Fig. 1 is an explanatory diagram showing a bag-shaped vinyl sheet 100 according to a first embodiment. More specifically, Fig. 1(a) is a plan view showing the bag-shaped vinyl sheet 100 according to the first embodiment in solid lines, the feces absorbent pad 10 to which the bag-shaped vinyl sheet according to the first embodiment is attached in two-dot chain lines on the outside, and the urine absorbent pad 20 to be inserted into the bag-shaped vinyl sheet 100 according to the first embodiment through an upper opening 110 and accommodated therein in two-dot chain lines on the inside.

[0039] Fig. 1(b) is a cross-sectional view showing the configuration shown in Fig. 1(a) in the longitudinal direction at the widthwise center thereof. In Fig. 1(b), the urine absorbent pad 20 contained inside the bag-shaped vinyl sheet 100 according to the first embodiment is shown by a dotted line, and the bag-shaped vinyl sheet 100 according to the first embodiment is shown superimposed on the absorbent surface of the feces absorbent pad 10.

[0040] In FIG. 1(b), the feces absorption pad 10 corresponds to the portion indicated by the dotted line at the bottom of the figure, and the bag-shaped vinyl sheet 100 of the first embodiment is shown with the cross-sectional portion hatched and the upper opening 110 not hatched.

[0041] Fig. 2 is an explanatory diagram showing a state in which the bag-shaped vinyl sheet 100 according to the first embodiment is attached to an excrement absorption pad 10 for a disposable diaper 50 (see Fig. 4). More specifically, Fig. 2(a) corresponds to Fig. 1(a) and is a plan view showing the bag-shaped vinyl sheet 100 according to the first embodiment actually attached to the excrement absorption pad 10.

[0042] In Fig. 1(a), the inner urine absorbent pad 20 and the outer feces absorbent pad 10 are indicated by a solid line, respectively. Fig. 2(b) is a longitudinal cross-sectional view corresponding to Fig. 1(b), and shows a state in which the urine absorbent pad 20 is actually housed inside the bag-shaped vinyl sheet 100 according to the first embodiment as in Fig. 1(a), and is laminated and attached on the upper side of the feces absorbent pad 10.

[0043] The bag-shaped vinyl sheet 100 for improving the functionality of an excrement absorption pad in this embodiment is used in a diaper for absorbing and treating excrement, which has a diaper body 50 and an excrement absorption pad 10 that is attached to the inside of this diaper body 50. Then, the excrement absorption pad (introduced as a feces absorption pad 10 in this embodiment) to which the bag-shaped vinyl sheet 100 for improving the functionality of the excrement absorption pad according to this embodiment is attached is attached to, for example, a disposable diaper 50, 60, and the user wears it for a certain period of time and excretes feces, urination, etc., and after the excrement is sufficiently absorbed by the absorbent material (introduced as a urine absorption pad 20 in this embodiment) set inside the excrement absorption vinyl sheet 100 or a significant portion of the excrement is collected inside the bag-shaped vinyl sheet 100, the disposable diaper 50, 60 can be removed from the user's body, or, for example, with the disposable diaper 50, 60 still partially worn, a caregiver can use their hands or fingers to remove the feces absorption pad 10 itself or just the bag-shaped vinyl sheet 100 and discard the absorbent material.

[0044] In addition to the above, the bag-shaped vinyl sheet 100 according to this embodiment can be made usable again by cleaning the bag-shaped vinyl sheet 100. After that, new absorbent material can be fitted inside again to return it to its original clean and hygienic state, and if the feces absorption pad 10 is not very dirty, it can be attached again, or if the feces absorption pad 10 is also dirty due to a part of the excrement flowing out, it can be replaced. This has special advantages in terms of recycling, as the disposable diapers 50, 60 that are usually soiled with excrement and must be discarded after each use can be reused as they are without being discarded, and in dramatically reducing the problem of increased costs due to replacing disposable diapers and feces absorption vinyl sheets every time.

[0045] As the absorbent material, tissue paper, toilet paper, paper towels, or commercially available absorbent pads may be used instead of the commercially available urine absorbent pad 20 used in this embodiment. This makes it possible to achieve a further significant cost reduction since it is no longer necessary to replace commercially available urine absorbent pads every time, in addition to the economic effect described above.

[0046] In the following first and second embodiments, the reference numeral 20 denotes a urine absorbent pad, but in the present invention, it is to be clearly stated that these are collectively referred to as absorbent pad 20 in a higher conceptual sense including the above-mentioned various absorbents. It should be noted that the above-mentioned special advantages are not only possessed by this embodiment (first embodiment) but also by the second embodiment described later and the modified examples of the first and second embodiments.

[0047] In this embodiment, the disposable diaper can be a commercially available disposable nursing diaper that is widely available. In the drawings explaining this embodiment, the diaper body 50 is shown in Fig. 4 as a pants-type diaper with an outer layer, and the inner layer is shown as a feces absorption pad 10 that mainly absorbs feces as excrement, while Fig. 5 also shows a tape-type outer layer in which the diaper body 50 is fixed to both sides of the waist with tape.

[0048] In addition, in this embodiment, the inner layer is a feces absorption pad 10, which is layered on top of a bag-shaped vinyl sheet 100 for improving the functionality of the excrement absorption pad. In addition, the embodiment will be described as a form in which a urine absorption pad 20, which is smaller than this pad, is housed inside the bag-shaped vinyl sheet 100 for improving the functionality of the excrement absorption pad.

[0049] However, the present invention is not limited to this form, and the former feces absorption pad 10 may be integrated with the latter urine absorption pad 20, and a bag-shaped vinyl sheet for improving the functionality of the excrement absorption pad may be placed on the upper surface of the urine absorption pad 20.

[0050] The bag-shaped vinyl sheet 100 for improving the functionality of an excrement absorption pad has a sheet shape formed by stacking two vinyl sheets 101, 102 each having a size that matches the excrement absorption surface of the excrement absorption pad 10. This vinyl sheet may be a commercially available vinyl bag of a size that produces the effect of this embodiment, and may be sealed so that excrement does not leak out from an opening at one end in the longitudinal direction, for example.

[0051] In addition, the material, thickness, and strength of the bag-shaped vinyl sheet 100 must be thick enough and strong enough that even if, after using the bag-shaped vinyl sheet 100 for improving the functionality of an excrement absorption pad, the caregiver lifts the bag-shaped vinyl sheet 100 upward near the upper opening when excrement has accumulated inside, excrement will not leak out from anywhere other than the upper opening 110 of the bag-shaped vinyl sheet 100.

[0052] Moreover, in the bag-shaped vinyl sheet 100 according to this embodiment, an upper opening 110 is formed in the vinyl sheet 101 on the upper side of the bag-shaped vinyl sheet 100 when viewed in a state in which the nursing diaper is worn by a user. The upper opening 110 is formed in a position so as to surround the excretion site including its periphery on the side of the surface that comes into close contact with the excretion site of the user when the nursing diaper is worn by the user.

[0053] In addition, in this embodiment, the upper opening 110 can accommodate the urine absorbent pad 20, for example by folding it, and the interior of the bag-shaped vinyl sheet 100 is large enough to allow the urine absorbent pad 20 to be unfolded and spread out inside (see Figures 3(a) and (b)).

[0054] More specifically, the shape of the upper opening 110 is formed in a plan view so that the peripheral portion has an oval shape or an elongated ellipse shape with both longitudinal sides of a so-called rectangle being semicircular. The size of the upper opening 110 is large enough to contain most of the excrement such as stool and urination that enters the bag-shaped vinyl sheet 100 through the upper opening 110 when the user of the nursing diaper excretes such as stool and urination, and to prevent a part of the excrement from leaking into the diaper main body 50.

[0055] In addition, the excrement absorption pad 10 that the user attaches to the inside of the diaper body 50 with the bag-shaped vinyl sheet 100 of this embodiment stacked on top of each other consists of the feces absorption pad 10 as described above, and the above-mentioned urine absorption pad 20, which is smaller in size than the feces absorption pad 10, is inserted and removed from the upper opening 110 of the bag-shaped vinyl sheet 100.

[0056] Next, a practical method of using the bag-shaped vinyl sheet for improving the functionality of an excrement absorbent pad according to the present invention will be described, including its functions and effects.

[0057] Fig. 3 is an explanatory diagram showing a procedure for attaching the bag-shaped vinyl sheet 100 according to the first embodiment to the excrement absorption pad 10. More specifically, Fig. 3(a) shows how to accommodate the urine absorption pad 20 shown in Fig. 2 in the bag-shaped vinyl sheet 100 according to the first embodiment. Fig. 3(b) shows a state in which the urine absorption pad 20 is accommodated in the bag-shaped vinyl sheet 100 according to the first embodiment from the upper opening 110 as shown in Fig. 3(a), and then the bag-shaped vinyl sheet 100 according to the first embodiment is attached to the feces absorption pad 10 in a superimposed manner, and each feces absorption pad 10 is folded and attached to the disposable diaper 50.

[0058] Fig. 4 is an explanatory diagram showing how the excrement absorption pad 10 having the bag-shaped vinyl sheet 100 according to the first embodiment is attached to a pants-type disposable diaper 50. More specifically, Fig. 4 shows how the excrement absorption pad 10 in the state shown in Fig. 3(b) is attached to a pants-type disposable diaper 50.

[0059] Fig. 5 is an explanatory diagram showing how the excrement absorption pad with the bag-shaped vinyl sheet 100 according to the first embodiment is attached to a disposable diaper 60 different from that shown in Fig. 4. More specifically, Fig. 5 is a drawing corresponding to Fig. 4, and while the disposable diaper 50 shown in Fig. 4 has a pants-type form, the disposable diaper 60 shown in Fig. 5 has a form in which the user attaches and fixes the upper left and right sides of the disposable diaper main body 60 to each other on both left and right sides around the waist.

[0060] First, prepare the bag-shaped vinyl sheet 100 for improving the functionality of an excrement absorption pad according to the present invention and a disposable diaper that is generally available on the market. This disposable diaper may be a pants-type disposable diaper 50 shown in Fig. 4 for explaining the present invention, or a disposable diaper 60 of the type shown in Fig. 5 that is worn by joining the left and right sides of the user's waist.

[0061] Then, the fecal absorbent pad 10 is laid out flat with its absorbent surface facing up, and the bag-shaped vinyl sheet 100 is placed on top of it, with its upper opening 110 positioned at the excretory part of the user's body when worn. The two are then placed in close contact so as not to slip. At this time, an adhesive that does not adversely affect the user's skin may be applied in advance to the four corners of the bag-shaped vinyl sheet 100 and in the longitudinal and transverse directions at appropriate intervals, and the two may be placed in close contact. Alternatively, so-called commercially available medical tape may be applied at appropriate intervals without using such an adhesive, and the two may be placed in close contact.

[0062] Furthermore, when performing the relative alignment required to bring the two parts into close contact with each other, it is important to adhere the two parts together while adjusting the upper opening 110 of the bag-shaped vinyl sheet 100 for improving the functionality of the excrement absorption pad so that the fecal excretion area and urination excretion area are located within the area of ​​this upper opening 110 when the disposable diaper is worn by the user.

[0063] Therefore, it is preferable to adjust the overlapping position of the two depending on whether the user of the disposable diaper is male or female. Also, if the user of the disposable diaper is male, even if the urination excretion part is not located within the area of ​​the upper opening, if the male genitalia can be accommodated inside the bag-shaped vinyl sheet 100 through the upper opening 110 of the bag-shaped vinyl sheet 100 when wearing the disposable diaper, the effect of the present invention can be achieved.

[0064] 3, the urine absorption pad 20 is folded from the upper opening 110 of the bag-shaped vinyl sheet 100 for improving the function of the excrement absorption pad, placed inside the bag-shaped vinyl sheet 100, and then laid out flat inside the bag-shaped vinyl sheet 100. The back side of the urine absorption pad 20 is usually coated with an adhesive to allow it to adhere to the feces absorption pad 10, so this is used to attach the pad to a suitable location on the lower part of the bag-shaped vinyl sheet 100 for improving the function of the excrement absorption pad (the lower vinyl sheet 102 on the side where no opening is formed) and the two are adhered to each other.

[0065] Then, the feces absorption pad 10, with the bag-shaped vinyl sheet 100 and the urine absorption pad 20 tightly fixed thereto, is attached to a predetermined position on the diaper body 50 of the disposable diaper as shown in Figures 4 and 5. This attachment method is the same as the attachment method for both the diaper body 50 and the feces absorption pad 10 that are originally commercially available. In this manner, the disposable diaper equipped with the bag-shaped vinyl sheet 100 for improving the function of the excrement absorption pad is put on the user.

[0066] Fig. 6 is an explanatory diagram showing the conventional problems when the present invention is not applied. More specifically, Fig. 6(a) shows a conventional state in which excrement such as stool and urination is completely absorbed by the excrement absorption pad 10 when the bag-shaped vinyl sheet 100 according to the first embodiment and the bag-shaped vinyl sheet 200 according to the second embodiment are not applied. Fig. 6(b) shows a state in which the excrement cannot be completely absorbed by the excrement absorption pad 10 when the care recipient further excrements after Fig. 6(a), and the excrement leaks out and adheres to the waist and the inside of the thighs, and also part of the excrement flows into the disposable diaper main body 50, 60, making it impossible to reuse the disposable diaper main body 50, 60.

[0067] 6(a) and 6(b) show the process of excretion of excrement when the caregiver is bedridden or nearly bedridden and lying on a bed or mattress, as seen from behind the caregiver. In addition, in Figs. 6(a) and 6(b) and Figs. 7(a) and 7(b) described below, the position of the excrement absorption pad 10 is shifted slightly downward with respect to the wearer's excretory area in order to facilitate understanding of the explanation.

[0068] If the bag-shaped vinyl sheet 100 for improving the functionality of the excrement absorption pad according to this embodiment is not used, excrement will leak out of the disposable diaper body 50, 60 and soil the bed sheet, the mattress body under the sheet, the futon, and the futon cover. As a result, it can be easily understood from this explanatory diagram that the extremely time-consuming extra work of replacing these and cleaning the mattress and futon themselves will be required.

[0069] In addition, when the hands, fingers, or arms of the caregiver become soiled with excrement leaking from the disposable diaper, it becomes necessary to frequently perform time-consuming washing to remove the dirt and odor. This eliminates the physical and mental burden, but also causes fungi and other substances contained in the excrement to remain on the hands, fingers, or arms of the caregiver, causing chronic and severe dermatitis.

[0070] On the other hand, FIG. 7 is an explanatory diagram showing the unique action and effect produced by the bag-shaped vinyl sheet 100 according to the first embodiment. More specifically, FIG. 7 is a drawing corresponding to FIGS. 6(a) and (b), and unlike FIG. 6, is a drawing showing the process in which a care recipient excretes excrement such as feces and urine using the bag-shaped vinyl sheet 100 according to the first embodiment, from the same direction as FIG. 6. FIG. 7(a) shows the process in which, when a care recipient excretes excrement such as feces and urine, these excrements are accumulated in the bag-shaped vinyl sheet 100 according to the first embodiment through the upper opening 110 of the bag-shaped vinyl sheet 100. Note that FIG. 7(b) shows a state in which the care recipient has excreted more excrement than in the state of FIG. 7(a), but the excrement is accumulated inside the bag-shaped vinyl sheet 100 according to the first embodiment and is maintained in a state in which it does not leak out from the outside as in FIG. 6(b).

[0071] As is clear from this drawing, when a user wears a disposable diaper body 50, 60 having a bag-shaped vinyl sheet 100 for improving the functionality of the excrement absorption pad of this embodiment attached at a predetermined position on the inner surface and excretes such as stool and urination, the excrement accumulates inside the bag-shaped vinyl sheet 100 through the upper opening 110 of the bag-shaped vinyl sheet 100.

[0072] Even if the user of the disposable diaper is bedridden or nearly bedridden, most of the excrement will remain accumulated inside the bag-shaped vinyl sheet 100 according to this embodiment. As a result, the caregiver's hands, fingers, and arms will be significantly reduced from becoming soiled with excrement leaking from the disposable diaper of the person being cared for when changing the disposable diaper.

[0073] As a result, the caregiver is no longer required to frequently perform extremely tedious and time-consuming washing to remove the dirt and odor of excrement from his / her hands, fingers, and arms, and the physical and mental burden associated with this is eliminated.In addition, it prevents fungi and other bacteria contained in excrement from remaining on the caregiver's hands, fingers, and arms, which may later cause chronic and severe dermatitis.

[0074] It also contributes to improving effectiveness by preventing excrement from sticking to the hands, fingers, and arms of caregivers when changing disposable diapers, particularly in cases where the excrement is bloody as described above or has become almost liquefied due to indigestion.

[0075] In addition, since excrement does not leak out of the disposable diaper and soil the bed sheets, the mattress underneath the sheets, the futon, or the futon cover, there is no need to carry out the extra work of replacing these or cleaning the mattress or futon themselves, which is extremely time-consuming.

[0076] This will significantly reduce the physical and mental burden on caregivers compared to before, and will also significantly reduce the burden on family members caring for the care recipient at home, as well as the burden on people working in care homes and hospitals.

[0077] Also, from the standpoint of the user of the disposable diaper, that is, the person receiving care, excrement such as stool, urine, and even bloody stool in some cases, will not adhere to the user's skin. In other words, in the case of an elderly person who is bedridden or nearly bedridden as in the past, excrement that could not be absorbed by the excrement absorption pad and leaks out to the surrounding area will leak out to the elastic part of the diaper body corresponding to the waist area, and will spread through the area where the elastic part is in close contact with the user due to the so-called capillary phenomenon, and will not only adhere to the user's excretion site and its surroundings, but will also leak out to unexpected body parts and adhere to a wide area.

[0078] According to the present invention, until the time of changing the disposable diaper, the excrement will not adhere to the skin of the cared for, causing sores or inflammation, and furthermore, fungi such as athlete's foot bacteria contained in the excrement will not spread to the skin of the cared for, causing unbearable itching or pain at the points where the bed sheets or futon cover are in close contact with the cared for body.

[0079] This will reduce the physical and mental burden on those receiving care, allowing them to live a comfortable life while improving frailty and sarcopenia and improving and restoring muscle strength throughout the body, enabling us to live to 100 years old and improving the quality of life (QOL) of those who are bedridden or nearly bedridden until they are able to walk to some extent.

[0080] In the above explanation, we have explained the advantages of using the bag-shaped vinyl sheet of this embodiment when people who are bedridden or close to being bedridden use disposable diapers. However, it goes without saying that anyone who needs to use disposable diapers on a daily basis, even if they are not such people, can achieve remarkable results by using the bag-shaped vinyl sheet for improving the functionality of the excrement absorption pad of this invention.

[0081] Specifically, for example, even elderly people who are able to live their daily lives may suffer from the anal sphincter becoming loose with age, and are unable to intentionally time their bowel movements. For such people, the use of the bag-shaped vinyl sheet for improving the functionality of excrement absorption pads according to the present invention is good news for them in terms of leading comfortable daily lives.

[0082] In other words, these people are unable to defecate at the right time in the toilet, and defecation occurs naturally from the anus whether they are awake, standing, sitting, or sleeping. Therefore, these people also start wearing disposable diapers on a daily basis, but the particular problem is that the liquid part of the feces naturally flows out of the anus and constantly soaks into the excrement absorption pad of the disposable diaper.

[0083] As a result, if an excrement absorption pad is worn for a long period of time, it will inevitably remain damp while it is being worn, causing the wearer to constantly suffer from an unpleasant feeling on the skin in that area, as well as the unpleasant smell of excrement wafting around, which can be a worry or source of depression, making it difficult to lead a comfortable and active daily life.

[0084] However, by using the bag-shaped vinyl sheet for improving the functionality of excrement absorption pads according to the present invention in disposable diapers that are used daily, such worries and problems can be solved. Specifically, when a certain amount of liquid excrement has accumulated, the disposable diaper is removed in a toilet or the like, and the excrement accumulated in the bag-shaped vinyl sheet for improving the functionality of excrement absorption pads is flushed into the toilet from the upper opening, and then the bag-shaped vinyl sheet for improving the functionality of excrement absorption pads is wrapped in toilet paper or the like, placed in a clean plastic bag, and the opening is tightly tied to prevent odors from leaking out. Of course, in an environment where the bag-shaped vinyl sheet according to the present invention can be washed with water or the like, the inside can be washed clean and reused.

[0085] This allows all of the excrement that flows out of the anus, including that which adheres to the skin, to be disposed of.Then, the bag-shaped vinyl sheet for improving the functionality of the new excrement absorption pad according to the present invention can be attached to the disposable diaper that was previously worn, making it possible to reuse the disposable diaper.

[0086] As described above, by continuing to use the structurally simple and extremely inexpensive bag-shaped vinyl sheet for improving the function of the excrement absorption pad according to the present invention by replacing it as necessary, it becomes possible to continue using the pad for a much longer period of time than when a disposable diaper is used without the bag-shaped vinyl sheet according to the present embodiment. As a result, it becomes possible to reduce the frequent disposal of expensive disposable diapers themselves and the economic burden that comes with it.

[0087] Next, a bag-shaped vinyl sheet 200 for improving the functionality of an excrement absorption pad according to a second embodiment of the present invention will be described with reference to the drawings. The bag-shaped vinyl sheet for improving the functionality of an excrement absorption pad according to this embodiment (hereinafter simply referred to as "the bag-shaped vinyl sheet 200 according to this embodiment" or simply "the bag-shaped vinyl sheet 200") has a basic configuration common to the first embodiment, but the shape of the upper opening 210 is different from that of the first embodiment, which provides a special effect. Therefore, the common configuration will be omitted in text and the shape of the upper opening and the effect based thereon will be described in detail.

[0088] Fig. 8 is an explanatory diagram showing a bag-shaped vinyl sheet 200 according to the second embodiment with its upper opening 210 closed and open. More specifically, Fig. 8(a) is a plan view showing, by solid lines, cutting lines 211-215 formed on an upper vinyl sheet 201 in a state before the upper opening 210 of the bag-shaped vinyl sheet 200 according to the second embodiment is formed. Fig. 8(b) is a plan view showing a state in which the cutting lines 211-215 in Fig. 8(a) are folded back to form folded-back portions 216-219, and at the same time, an elongated rectangular upper opening 210 is formed in the bag-shaped vinyl sheet 200.

[0089] Fig. 9 is an explanatory diagram showing a state in which a bag-shaped vinyl sheet 200 according to the second embodiment is attached to an excrement absorption pad 10 of a disposable diaper. More specifically, Fig. 9(a) is a plan view showing a state in which the bag-shaped vinyl sheet 200 according to the second embodiment shown in Fig. 8(b) is superimposed on the upper surface of the excrement absorption pad 10 and fixed so as not to shift.

[0090] Fig. 9(b) is a cross-sectional view showing the state of Fig. 9(a) cut across the entire lengthwise direction at the widthwise center, showing the urine absorbent pad 20 housed inside through the upper opening 210 of the bag-shaped vinyl sheet 200 according to the second embodiment, and the feces absorbent pad 10 with the bag-shaped vinyl sheet according to the second embodiment overlaid on the upper surface and fixed to prevent slippage. Note that in Figs. 9(a) and 9(b), the bag-shaped vinyl sheet 200 is drawn as transparent, so the urine absorbent pad 20 is also drawn transparently with solid lines. The same applies to the other figures corresponding to these figures.

[0091] Fig. 10 is an explanatory diagram showing a procedure for attaching the bag-shaped vinyl sheet 200 according to the second embodiment to the excrement absorbent pad 10. More specifically, Fig. 10(a) shows a method for storing the urine absorbent pad 20 shown in Fig. 9 in the bag-shaped vinyl sheet 200 according to the second embodiment.

[0092] Also, Figure 10(b) shows the state immediately before the urine absorption pad 20 is placed into the bag-shaped vinyl sheet 200 of the second embodiment through the upper opening 210 as shown in Figure 10(a), the bag-shaped vinyl sheet 200 of the second embodiment is layered and attached to the feces absorption pad 10, and the feces absorption pad 10 is folded and attached to a disposable diaper.

[0093] Fig. 11 is an explanatory diagram showing how an excrement absorbent pad 10 with a bag-shaped vinyl sheet 200 according to the second embodiment is attached to a pants-type disposable diaper 50. More specifically, Fig. 11 shows how the feces absorbent pad 10 and the urine absorbent pad 20 and the bag-shaped vinyl sheet 200 shown in Fig. 10 are attached to the pants-type disposable diaper 50 in a state where they are overlapped in a predetermined manner so as not to shift.

[0094] Fig. 12 is an explanatory diagram showing how an excrement absorption pad 10 having a bag-shaped vinyl sheet 200 according to a second embodiment is attached to a disposable diaper 60 different from that shown in Fig. 11. More specifically, Fig. 12 is a drawing corresponding to Fig. 11, and while the disposable diaper 50 shown in Fig. 11 has a pants-type form, the disposable diaper 60 shown in Fig. 12 has a form in which the user attaches and fixes the upper left and right sides of the disposable diaper main body 60 to each other on both left and right sides around the waist.

[0095] FIG. 13 is an explanatory diagram showing the unique action and effect produced by the bag-shaped vinyl sheet 200 according to the second embodiment. More specifically, FIG. 13 is a drawing corresponding to FIG. 6 and FIG. 7, and unlike FIG. 7, it is a drawing showing the process in which a care recipient excretes excrement such as feces and urine using the bag-shaped vinyl sheet 200 according to the second embodiment, from the same direction as FIG. 6 and FIG. 7. FIG. 13(a) shows the process in which, when a care recipient excretes excrement such as feces and urine, these excrements are accumulated in the bag-shaped vinyl sheet 200 from the upper opening 210 of the bag-shaped vinyl sheet 200 according to the second embodiment. FIG. 13(b) shows a state in which the care recipient has excreted more excrement than in the state of FIG. 13(a), but the excrement is accumulated inside the bag-shaped vinyl sheet 200 and is maintained in a state in which it does not leak out from the outside (compare with FIG. 6).

[0096] The contents corresponding to the above drawings will be explained in more supplementary detail. The bag-shaped vinyl sheet 200 for improving the function of an excrement absorption pad according to the second embodiment is a disposable diaper for excrement absorption processing, which has a diaper body 50 and an excrement absorption pad 10 attached inside the diaper body 50, as in the first embodiment, and is used in a disposable diaper for excrement absorption processing, which is worn by a user and absorbs excrement with the excrement absorption pad 10, and then the excrement absorption pad 10 is discarded and a new excrement absorption pad 10 is attached to the diaper body for reuse.

[0097] The excrement absorption pad 10 to which the bag-shaped vinyl sheet 200 according to the second embodiment of the present invention is attached is made of a stool absorption pad, as in the first embodiment. The bag-shaped vinyl sheet 200 has a sheet shape formed by overlapping two vinyl sheets 201, 202 each having a size matching the excrement absorption surface of the excrement absorption pad 10, and has cuts 211-215 on the upper part of the bag-shaped vinyl sheet 200 for forming an upper opening 210 that surrounds the excrement site including its periphery when the bag-shaped vinyl sheet 200 is opened on the side of the excrement absorption pad 10 that comes into close contact with the excrement site of the user when the disposable diaper is worn by the user.

[0098] By forming the above-mentioned cut portions 211-215, the cut portions 211-215 can be used to form the upper opening 210 similar to that of the first embodiment. This prevents at least a significant portion of the excrement, such as stool or urination, from leaking into the bag-shaped vinyl sheet 200 through the upper opening 210 formed together with the folded-back portions 216-219 by folding back the cut portions 211-215, and thus prevents a portion of the excrement from leaking into the diaper main body 50.

[0099] The upper opening 210 of the bag-shaped vinyl sheet 200 according to the second embodiment is large enough to allow the urine absorbent pad 20 to be inserted and removed, as in the first embodiment. The urine absorbent pad 20 can be inserted into the bag-shaped vinyl sheet 200 via the upper opening 210 and stored in the bag-shaped vinyl sheet 200 so that the urine absorbent pad 20 can be maintained in a state in which it can absorb urine as excrement when the disposable diaper is worn by a user.

[0100] Next, the configuration of the cutouts 211-215 for forming the upper opening 210, which is a configuration feature unique to the second embodiment, will be described in more detail. The cutouts 211-215 are formed in the upper vinyl sheet 201 of the bag-shaped vinyl sheet 200, from a first cutout 211 extending a certain length along the longitudinal direction in the middle of the width of the bag-shaped vinyl sheet 200, and second cutouts 212, 213 and third cutouts 214, 215 formed at both ends of the first cutout 211 to form a substantially V-shape and extending from each of the V-shape ends to approach the longitudinal and widthwise ends of the bag-shaped vinyl sheet at a certain angle to the first cutout 211, respectively. In this embodiment, both of the second cuts 212, 213 and the third cuts 214, 215 are substantially V-shaped, with their acute angled tips connected to one end 211a and the other end 211b of the first cut 211, respectively.

[0101] The first cut 211, the second cut 212, 213, and the third cut 214, 215 formed in the upper vinyl sheet 201 of the bag-shaped vinyl sheet 200 may be completely cut as shown by solid lines in Fig. 8(a), or may be cut in a perforated pattern at a predetermined interval. In this case, if the cut is perforated, it is preferable that the cut is formed in such a way that the user can easily separate the sheet by pinching the periphery with their fingers and pulling. Alternatively, the cut may be formed by combining a complete cut line and a perforated cut line.

[0102] Next, a method for forming the upper opening 210 will be described. The upper vinyl sheet 201 of the bag-shaped vinyl sheet 200 shown in Fig. 8(a) is pinched with the fingers, and the first cut-out portions 211 are folded back up and down in the figure, while the second cut-out portions 212 and 213 are folded back to the left in the figure, and the third cut-out portions 214 and 215 on the right side are folded back to the right in the figure, forming folded-back portions 216-219 as shown in Fig. 8(b), resulting in an open, unfolded state.

[0103] As a result, an elongated rectangular upper opening 210 having a predetermined width along the longitudinal direction is formed in the center. This upper opening 210 corresponds to the semicircular irregular rectangular (elliptical) upper openings 110 formed in the bag-shaped vinyl sheet 100 of the first embodiment.

[0104] The material of the bag-shaped vinyl sheet 200 for improving the function of the excrement absorption pad 10 according to the second embodiment has a firm thickness similar to that of the first embodiment. As a result, when the first cut portion 211, the second cut portions 212 and 213, and the third cut portions 214 and 215 are all folded back as shown in Fig. 8(b), all the folded back portions 216 to 219 are slightly curved upwards due to a certain degree of elasticity when viewed on the paper surface of Fig. 8(b).

[0105] The advantages of the feature that each of the folded-back portions 216 to 219 is slightly upwardly directed toward the tip of the folded-back portion while maintaining a certain degree of elasticity will be described below.

[0106] In this state, when the bag-shaped vinyl sheet 200 according to the second embodiment is attached to the excrement absorption pad 10 and then attached to the diaper body 50, 60, when the user puts on the disposable diaper 50, 60, all the folded-up parts are pressed against the user's skin and tightly adhere to the skin. Since the folded-up parts 216-219 and their surroundings adhere to the user's skin in this way, no gaps are generated between the folded-up parts 216-219 and parts of the user's body. In other words, regardless of differences in the physique or shape of each user, and even if there is a lump or a large protrusion (a growth or swelling), the folded-up parts can be adhered tightly along the outer surface without leaving any gaps.

[0107] This reliably prevents excrement from leaking out of the bag-shaped vinyl sheet 200 according to the second embodiment via the skin from these tightly fitting portions when excrement is excreted while wearing the disposable diaper. In other words, excrement is collected without leakage from the upper opening 210 inside the bag-shaped vinyl sheet 200 and reliably prevents it from leaking out (see FIG. 13).

[0108] In addition to the above explanation, the bag-shaped vinyl sheet 200 of this embodiment exhibits even better effects on the above-mentioned problems arising from relaxation of the anal sphincter than those of the bag-shaped vinyl sheet 100 of the first embodiment.

[0109] Next, a bag-shaped vinyl sheet 300 for improving the functionality of an excrement absorption pad according to a third embodiment of the present invention will be described. In this third embodiment, as described in the section on problems to be solved above, it will be explained that a remarkable effect can be achieved by supplementing the urine leakage absorption pad 30 used by women.

[0110] When urine leakage reaches a serious level, even if the urine leakage absorbent pad 30 is worn, urine leaks out from between the urine leakage absorbent pad 30 and the skin, and adheres to underwear and clothes, staining them, and the smell spreads to the surroundings, which is bothersome. On the other hand, the bag-shaped vinyl sheet 300 according to the third embodiment is conceived to solve such problems and allow people to live a more comfortable daily life.

[0111] FIG. 14 is an explanatory diagram showing a first embodiment 300-1 of the bag-shaped vinyl sheet 300 according to the third embodiment. More specifically, FIG. 14(a) shows the first embodiment 300-1 of the bag-shaped vinyl sheet 300 according to the third embodiment in a plan view by solid lines, and shows the urine leakage absorbent pad 30 to which the first embodiment 300-1 of the bag-shaped vinyl sheet 300 according to the third embodiment is attached by a two-dot chain line on the outside. Also, FIG. 14(b) is a cross-sectional view of the configuration shown in FIG. 14(a) cut in the longitudinal direction at the center in the width direction. This figure shows the state in which the first embodiment 300-1 of the bag-shaped vinyl sheet 300 according to the third embodiment is superimposed and attached to the absorbing surface of the urine leakage absorbent pad 30. In Figure 14(b), the urine leakage absorbent pad 30 of the third embodiment corresponds to the portion indicated by the dotted line at the bottom of the figure, and a first example 300-1 of the bag-shaped vinyl sheet 300 of the third embodiment is indicated by a solid line with the cross-sectional portion indicated by hatching, and its upper opening 310 is shown without hatching.

[0112] Fig. 15 is an explanatory diagram showing a state where a first embodiment 300-1 of a bag-shaped vinyl sheet 300 according to the third embodiment is attached to a urine leakage absorbent pad 30. More specifically, Fig. 15(a) is a drawing corresponding to Fig. 14(a) and shows a plan view of the first embodiment 300-1 of the bag-shaped vinyl sheet 300 according to the third embodiment actually attached to the urine leakage absorbent pad 30. In Fig. 15(a), the urine leakage absorbent pad 30 and this modification 300-1 are each shown by solid lines. In Fig. 15(b), a drawing corresponding to Fig. 15(a), shows a state where the first embodiment 300-1 of the bag-shaped vinyl sheet 300 according to the third embodiment is attached to the upper side of the urine leakage absorbent pad 30 in a superimposed manner.

[0113] Fig. 16 is an explanatory diagram showing a second example 300-2 of a bag-shaped vinyl sheet 300 according to the third embodiment. More specifically, Fig. 16(a) is a plan view showing, by solid lines, cutting lines 321-325 formed on an upper vinyl sheet 301-2 in a state before an upper opening 320 is formed in the second example 300-2 of the bag-shaped vinyl sheet 300 according to the third embodiment. Fig. 16(b) is a plan view showing a state in which the cutting lines 321-325 in Fig. 16(a) are folded back to form an elongated rectangular upper opening 320 on the upper side of the bag-shaped vinyl sheet.

[0114] Fig. 17 is an explanatory diagram showing a state where a second embodiment 300-2 of the bag-shaped vinyl sheet 300 according to the third embodiment is attached to a urine leakage absorbent pad 30. More specifically, Fig. 17(a) is a plan view showing a state where the second embodiment 300-2 of the bag-shaped vinyl sheet 300 according to the third embodiment shown in Fig. 16 is overlapped on the upper surface of the urine leakage absorbent pad 30 and fixed so as not to shift. Fig. 17(b) is a cross-sectional view showing the state of Fig. 17(a) cut in the entire longitudinal direction at the widthwise center, showing the urine leakage absorbent pad 30 where the second embodiment 300-2 of the bag-shaped vinyl sheet 300 according to the third embodiment is overlapped on the upper surface and fixed so as not to shift.

[0115] The contents corresponding to the above drawings will be explained in more detail. The bag-shaped vinyl sheet 300 for improving the function of the excrement absorption pad according to the third embodiment has a sheet shape formed by overlapping two vinyl sheets 301-2, 302-2 having a size corresponding to the excrement absorption surface of the urine leakage absorption pad 30 for absorbing urine that accidentally leaks out. In addition, when the urine leakage absorption pad 30 is worn by a user, the bag-shaped vinyl sheet 300-2 has upper openings 310, 320 formed to surround the excretion site and its vicinity on the side of the surface of the bag-shaped vinyl sheet 300-2 that comes into close contact with the excretion site of the user of the urine leakage absorption pad 30, on the upper part of the bag-shaped vinyl sheet.

[0116] At least a significant portion of the urine (hereinafter referred to as "excrement") leaking onto the urine leakage absorbent pad 30 enters the bag-shaped vinyl sheet through the upper openings 310, 320, thereby preventing a portion of the leaked urine from leaking outside the urine leakage absorbent pad 30.

[0117] The respective forms of the bag-shaped vinyl sheet having the above-mentioned two upper openings 310, 320 will be specifically described below as a first embodiment and a second embodiment. With regard to the drawings, Figs. 14 and 15 correspond to the first embodiment, and Figs. 16 and 17 correspond to the second embodiment. With regard to the reference numerals shown in each drawing, the reference numerals on the left side not enclosed in parentheses correspond to the first and second embodiments of this second embodiment, respectively.

[0118] The first example 300-1 has the same shape as the first embodiment described above. Specifically, the upper opening 310 (see Figs. 14 and 15) is shaped to have an oval shape or an elongated ellipse shape with a peripheral portion of a so-called rectangle having semicircular longitudinal sides in a plan view. The size of the upper opening 310 is such that at least a significant portion of the excrement enters the bag-shaped vinyl sheet 300-1 through the upper opening 310 and contains most of the excrement, thereby preventing a portion of the excrement from leaking out of the urine leakage absorbent pad 30.

[0119] The second example 300-2 has the same shape as the second embodiment described above. Specifically, the bag-shaped vinyl sheet 300 has a sheet shape formed by overlapping two vinyl sheets 301-2 and 302-2, each having a size matching the excrement absorption surface of the urine leakage absorbent pad 30, and has cuts 321-325 in the upper part of the bag-shaped vinyl sheet 300-2 on the side of the bag-shaped vinyl sheet 300-2 that comes into close contact with the excretion site of the user (see FIG. 17) for forming an upper opening 320 surrounding the excretion site and its vicinity, when the urine leakage absorbent pad 30 is worn by the user.

[0120] These cut portions 321-325 are folded back in the same manner as in the second embodiment to form folded back portions 326-329, thereby forming an upper opening 320 similar to that in the second embodiment. This prevents at least a significant portion of excrement from leaking out of the urine leakage absorbent pad 30 by entering the bag-shaped vinyl sheet 300-2 through the upper opening 320 formed by the folded back portions 316-319 when the excrement is discharged.

[0121] For confirmation, we will now explain the specific shapes of the cuts 321-325 and how to fold them back to form the upper opening 320. The cuts 321-325 are formed in the upper vinyl sheet 301-2 of the bag-shaped vinyl sheet 300-2, with a first cut 321 extending a certain length along the longitudinal direction in the middle of the width of the bag-shaped vinyl sheet 300-2, and second cuts 322, 323 and third cuts 314, 315 formed at both ends of the first cut 321 to form a substantially V-shape, and extending from each end of the V-shape at a certain angle to the first cut 321 so as to approach the longitudinal and widthwise ends of the bag-shaped vinyl sheet 300-2. In this embodiment, both the second cut portion and the third cut portion are substantially V-shaped, and the acute angled portions of the V-shaped portions are connected to the ends 321a, 321b of the first cut portion 321, respectively.

[0122] The first cut 321, second cut 322, 323, and third cut 314, 315 formed in the upper vinyl sheet 301-2 of the bag-shaped vinyl sheet 300-2 may be completely cut as shown by solid lines in Fig. 16(a), or may be cut in a perforated pattern at a predetermined interval. Also, a combination of completely cut portions and perforated cut portions may be used. When cut in a perforated pattern, it is preferable that the cut portions are formed in a shape that allows the user to easily separate the sheet by pinching the periphery with their fingers and pulling it.

[0123] Next, a method of forming the upper opening 320 will be described with reference to Figs. 16(a)(b) and 17(a)(b). First, the upper vinyl sheet 301-2 of the bag-shaped vinyl sheet 300-2 having the same cuts as in the second embodiment is pinched with fingers, and the first cuts 321 are folded up and down in the drawing, the second cuts 322, 323 are folded leftward in the drawing, and the right third cuts 324, 325 are folded rightward (see the change from the configuration shown in Figs. 16(a)(b) to the configuration shown in Figs. 17(a)(b)). As a result, the folded and unfolded state is the same as that shown in the second embodiment, and an elongated rectangular upper opening 320 (see Fig. 17(a)) having a predetermined width along the longitudinal direction is formed in the center. The upper opening 320 of this embodiment corresponds to the upper opening 210 of the second embodiment.

[0124] The material of the bag-shaped vinyl sheet 300 in the third embodiment has a firm thickness similar to that in the second embodiment. As a result, when the first cut portion 321, the second cut portions 322 and 323, and the third cut portions 324 and 325 similar to those in the second embodiment are all folded back, all of the folded back portions 326 to 329 are slightly curved upwards due to a certain degree of elasticity when viewed on the paper surface of FIG. 17(b).

[0125] The advantages of the feature that the folded portions 326 to 329 shown in FIGS. 17(a) and 17(b) are each slightly upwardly directed toward the tip of each of these folded portions due to a certain degree of elasticity will now be described.

[0126] When the embodiment having the upper opening 320 formed by folding as described above is attached to the urine leakage absorbent pad 30 shown in Figures 16 and 17 using adhesive tape, medical bandage, etc. and the user wears the urine leakage absorbent pad 30, the elasticity generated by folding all of the folded portions 326 to 329 is utilized to press the pad against the user's skin and adhere firmly to the skin.

[0127] In this way, the folded-over portion and its surroundings are in close contact with the skin of the user, so that the pad can be adapted to the different body shapes of all users, and even if there is a lump or a large protrusion (a bump or swelling) on ​​the part of the body that the pad is in contact with, the pad can be in close contact with the outer surface without leaving any gaps. This ensures that even if urine accidentally leaks while wearing the urinary leakage absorbent pad 30, the leaked urine can be reliably prevented from leaking out of the urinary leakage absorbent pad 30 along the skin.

[0128] As is clear from this configuration, the basic configuration of the bag-shaped vinyl sheet 300 in the third embodiment is the same as the configurations of the first and second embodiments described above, but differs in that the length and width of the bag-shaped vinyl sheet 300, and the shape, size and formation position of the upper opening 310 have optimal dimensions and shapes to suit the intended application.

[0129] Next, a bag-shaped vinyl sheet 400 for improving the functionality of an excrement absorption pad according to a fourth embodiment of the present invention will be described. This fourth embodiment solves all the problems described in the above-mentioned section on problems to be solved in one fell swoop, and can provide a remarkable effect when used as a supplement to a sanitary napkin 40 used by women.

[0130] In the following explanation, in order to distinguish between feces and urination as mere excrement and the original meaning of menstruation, the term "excrement" will be used instead of "excrement", and the name of this invention will be explained as "bag-shaped vinyl sheet for improving the functionality of excrement absorption pads".

[0131] More specifically, when a woman has a heavy period, even if she is wearing a sanitary napkin 40, waste leaks out from between the sanitary napkin 40 and her skin, and sticks to her underwear or clothes, staining them and spreading an unpleasant odor to the surroundings, which can be troublesome.

[0132] Therefore, in the fourth embodiment, the idea is to solve such problems by applying the present invention, thereby enabling people to live more comfortable daily lives.

[0133] Fig. 14 is an explanatory diagram showing a first example 400-1 of the bag-shaped vinyl sheet 400 according to the fourth embodiment. More specifically, Fig. 14(a) shows the first example 400-1 of the bag-shaped vinyl sheet 400 according to the fourth embodiment in a plan view by solid lines, and shows the sanitary product (napkin) 40 to which the bag-shaped vinyl sheet 400 of the fourth embodiment is attached by a two-dot chain line on the outside. Fig. 14(b) is a cross-sectional view of the configuration shown in Fig. 14(a) cut in the longitudinal direction at the center in the width direction. This figure shows a state in which the first example of the bag-shaped vinyl sheet 400 according to the fourth embodiment is superimposed and attached to the absorbing surface of the sanitary product (napkin). In Figure 14(b), the sanitary product (napkin) 40 corresponds to the portion indicated by the dotted line at the bottom of the figure, and a first example 400-1 of a bag-shaped vinyl sheet 400 relating to the fourth embodiment is shown by a solid line with the cross-sectional portion indicated by hatching, and its upper opening 410 is shown without hatching.

[0134] FIG. 15 is an explanatory diagram showing a state where a first embodiment 400-1 of a bag-shaped vinyl sheet 400 according to the fourth embodiment is attached to a sanitary product (napkin) 40. More specifically, FIG. 15(a) is a drawing corresponding to FIG. 14(a), and shows a plan view of the first embodiment 400-1 of the bag-shaped vinyl sheet 400 according to the fourth embodiment actually attached to a sanitary product (napkin) 40. In FIG. 15(a), the sanitary product (napkin) 40 and the first embodiment 400-1 of the bag-shaped vinyl sheet 400 of this embodiment are each shown by solid lines. In addition, FIG. 15(b) shows a state where the first embodiment 400-1 of the bag-shaped vinyl sheet 400 according to the fourth embodiment is attached to the upper side of the sanitary product (napkin) 40.

[0135] Fig. 16 is an explanatory diagram showing a second example 400-2 of a bag-shaped vinyl sheet 400 according to the fourth embodiment. More specifically, Fig. 16(a) is a plan view showing, by solid lines, cutting lines 421-425 formed on an upper vinyl sheet 401-2 in a state before forming an upper opening 420 of the second example 400-2 of the bag-shaped vinyl sheet 400 according to the fourth embodiment. Fig. 16(b) is a plan view showing a state in which the cutting lines 421-425 in Fig. 16(a) are folded back to form an elongated rectangular upper opening 420 on the upper side of the second example 400-2 of the bag-shaped vinyl sheet 400.

[0136] Fig. 17 is an explanatory diagram showing a state where a second embodiment 400-2 of the bag-shaped vinyl sheet 400 according to the fourth embodiment is attached to a sanitary product (napkin) 40. More specifically, Fig. 17(a) is a plan view showing a state where the second embodiment 400-2 of the bag-shaped vinyl sheet 400 according to the fourth embodiment shown in Fig. 16 is overlapped on the upper surface of the sanitary product (napkin) 40 and fixed so as not to shift. Fig. 17(b) is a cross-sectional view showing the state of Fig. 17(a) cut in the entire longitudinal direction at the widthwise center, showing a sanitary product (napkin) 40 where the second embodiment 400-2 of the bag-shaped vinyl sheet 400 according to the fourth embodiment is overlapped on the upper surface and fixed so as not to shift.

[0137] With regard to Figures 14 to 17, in explaining the third and fourth embodiments, there are differences in the dimensions such as size, length, and width, and differences in the thickness and materials of each embodiment, but since the basic configuration is common, these drawings will be used as common drawings, and with regard to the reference symbols, the reference symbols of the third embodiment will be written on the left side, and the reference symbols of the fourth embodiment will be written in parentheses to the right of each reference symbol of the third embodiment.

[0138] The contents corresponding to the above drawings will be explained in more supplementary detail. The bag-shaped vinyl sheet 400 for improving the function of the excrement absorption pad according to the fourth embodiment has a sheet shape formed by overlapping two vinyl sheets having a size corresponding to the excrement absorption surface of the excrement absorption pad, and upper openings 410, 420 are formed in the upper part of the bag-shaped vinyl sheet 400 on the side of the bag-shaped vinyl sheet 400 that comes into close contact with the excrement site of the user when the excrement absorption pad 40 is worn by the user, so as to surround the excrement site and its vicinity.

[0139] When waste material is discharged into the waste absorption pad 40, at least a significant portion of the waste material enters the bag-shaped vinyl sheet 400 through the upper openings 410, 420, thereby preventing a portion of the waste material from leaking out into the waste absorption pad 40.

[0140] There are two possible shapes for the upper openings 410 and 420. The first embodiment has the same shape as the third embodiment described above. Therefore, with regard to the reference symbols in the drawings, the reference symbols specific to the first embodiment of the fourth embodiment are shown in parentheses in Figs. 14 and 15. Specifically, the shape of the upper opening 410 is formed so that the peripheral portion is an oval shape or an elongated ellipse shape in which both longitudinal sides of a so-called rectangle are semicircular in plan view. The size of the upper opening 410 is such that when waste is discharged, at least a significant portion of the waste enters the bag-shaped vinyl sheet 400 from the upper opening 410 and contains most of the waste, thereby preventing a portion of the waste from leaking out of the napkin 40.

[0141] Also, the second embodiment 400-2 has the same shape as the second embodiment of the third embodiment described above. Therefore, with regard to the symbols in the drawings, the unique symbols related to the second embodiment of the fourth embodiment are shown in parentheses in Fig. 16 and Fig. 17. Specifically, the bag-shaped vinyl sheet 400-2 has a sheet shape formed by overlapping two vinyl sheets 401-2, 402-2 having a size corresponding to the excrement absorption surface of the excrement absorption pad 40, and has cut portions 421-425 in the upper part of the bag-shaped vinyl sheet 400 on the side of the bag-shaped vinyl sheet 400 that comes into close contact with the user's excrement site when the napkin 40 is worn by the user, for forming an upper opening 420 surrounding the excrement site and its vicinity.

[0142] Then, by folding back these cuts 421-425 in the same manner as in the second embodiment, folded back portions 426-429 which themselves have elasticity are formed, and an upper opening 420 similar to that of the second example 300-2 of the third embodiment is formed. This prevents at least a significant portion of the waste from entering the bag-shaped vinyl sheet 400-2 through the upper opening 420 formed by folding back the cuts 421-425 when the waste is discharged, and prevents a portion of the waste from leaking out of the napkin 40.

[0143] For confirmation, we will now explain the specific shapes of the cuts 421-425 and how to fold them back to form the upper opening 420. The cuts 421-425 are formed in the upper vinyl sheet 401-2 of the bag-shaped vinyl sheet 400-2, with a first cut 421 extending a certain length along the longitudinal direction in the widthwise center of the bag-shaped vinyl sheet 400-2, and second and third cuts formed at both ends of the first cut 421 in a substantially V-shape and extending from both ends 421a, 421b of the first cut 421 at a certain angle to the first cut 421 so as to approach the longitudinal and widthwise ends of the bag-shaped vinyl sheet 400-2. In this embodiment, both of the second cut portions 422, 423 and the third cut portions 424, 425 are substantially V-shaped, and their acute angled tips are connected to both ends 421a, 421b of the first cut portion 421, respectively.

[0144] The first cut portion 421, the second cut portions 422, 423, and the third cut portions 424, 425 formed in the upper vinyl sheet 401-2 of the bag-shaped vinyl sheet 400-2 may be completely cut as shown in FIG. 8 showing the second embodiment, or may be cut in a perforated pattern at a predetermined interval. Also, a completely cut portion and a perforated cut portion may be combined. When cut in a perforated pattern, it is preferable that the cut portions are formed in a shape that allows the user to easily separate the portions by pinching the periphery with their fingers and pulling them.

[0145] A method of forming the upper opening 420 will be described. The upper vinyl sheet 401-2 of the bag-shaped vinyl sheet 400-2 having the same cuts as those of the second embodiment shown in FIG. 16(a) is pinched with fingers, and the first cut portion 421 is folded up and down in the drawing, while the second cut portions 422 and 423 are folded leftward in the drawing, and the third cut portions 424 and 425 are folded rightward. This results in a folded and developed state as shown in FIG. 17(a) and (b) showing the second example of the third embodiment, and a long and narrow rectangular upper opening having a predetermined width along the longitudinal direction is formed in the center. The upper opening 420 of this embodiment corresponds to the upper opening 320 of the second example of the third embodiment.

[0146] The material of the second example 400-2 of the bag-shaped vinyl sheet 400 for improving the performance of the excrement absorption pad of the fourth embodiment has a firm thickness similar to the second example 300-2 of the second and third embodiments. As a result, when the first cut portion 421, the second cut portions 422, 423, and the third cut portions 424, 425 are all folded back as shown in Fig. 8(b) showing the second embodiment, all the folded back portions 426 to 429 are folded back slightly upwards due to a certain degree of elasticity as viewed on the paper surface of Fig. 8(b).

[0147] The advantages of the feature that each of the folded portions 426 to 429 is slightly warped upward toward the tip of each of the folded portions 426 to 429 due to a certain degree of elasticity will now be described.

[0148] The embodiment having the upper opening 420 formed by folding as described above is attached to the napkin 40 using adhesive tape, a medical bandage, or the like, and then when the user puts on the napkin 40, all of the folded parts are pressed against the user's skin and firmly worn. This allows the folded parts 426-429 and their surroundings to adhere to the user's skin, making it possible to adapt to all different body shapes of each user, and even if the part of the body to be adhered to has a lump or a large protrusion (a growth or swelling), it can be adhered to the outer surface without leaving any gaps.

[0149] This reliably prevents waste material discharged while wearing the napkin 40 from leaking from these close-fitting portions along the skin to the outside of the bag-shaped vinyl sheet 400 for improving the performance of the waste absorption pad according to the fourth embodiment. As a result, waste material is collected without leakage from the upper opening 420 inside the bag-shaped vinyl sheet 400 for improving the performance of waste material and reliably prevents it from leaking to the outside.

[0150] As is clear from this configuration, the basic configuration of the bag-shaped vinyl sheet 400 for improving the functionality of an excrement absorption pad in the fourth embodiment is the same as the configuration of the bag-shaped vinyl sheet 200 for absorbing excrement in the second embodiment described above, and particularly the bag-shaped vinyl sheet 300-2 for absorbing excrement in the second example of the third embodiment (see Figures 16 and 17), but has optimal dimensions and shapes in terms of the length and width of the bag-shaped vinyl sheet 400-2, the shape, size and formation position of the upper opening 420, to suit the intended aspect.

[0151] As can be understood from the above explanation, the problem caused by the leakage of such excrement can be solved by attaching the bag-shaped vinyl sheet 400 for improving the performance of the excrement absorption pad 10 according to the present invention to the sanitary product (napkin) 40 and wearing it. The reason for this is that when the excrement is excreted, at least a significant portion of the excrement enters the bag-shaped vinyl sheet 400 through the upper opening 420 of the bag-shaped vinyl sheet 400, preventing a portion of the excrement from leaking out to the excrement absorption pad.

[0152] This will solve the problems that regularly plague women who are trying to play an active role in society, in line with the recent trend of gender equality in society, and will improve the performance of women who participate in society. In addition, women can enjoy themselves without hesitation when dining out with friends or acquaintances when they have a heavy period. In addition, women can do housework and raise children at home without feeling any extra stress, even when they have a heavy period.

[0153] Furthermore, as a fifth embodiment, as described in the above-mentioned Problems to be solved, the present invention can also be applied to a disposable diaper for infants. Specifically, regardless of whether the disposable diaper for infants is formed with a diaper body and an excrement absorption pad attached inside the diaper body as separate bodies like the above-mentioned nursing diaper, or is formed as an integral body, the bag-shaped vinyl sheet for improving the function of the excrement absorption pad according to the present invention can be attached to the excrement absorption pad forming portion of the disposable diaper.

[0154] This prevents excrement from a baby who is unable to take off the diaper from leaking into the diaper body, making the task of changing diapers, which must be done periodically, simple and quick, and reducing physical and mental stress for the caregiver.

[0155] The bag-shaped vinyl sheet for improving the functionality of excrement absorption pads according to the present invention described above is not limited to the above-mentioned usage, and can be used in various other situations to achieve the unique effects of the present invention. Specific examples of the applications of the present invention include divers, deep-sea submarine crew members, long-distance truck drivers, and women's toilet substitutes when driving home during traffic jams, and by using the bag-shaped vinyl sheet for improving the functionality of excrement absorption pads according to the present invention, the excrement absorption pads and the diaper body that contains them can be used repeatedly several times.

[0156] Furthermore, the bag-shaped vinyl sheet for improving the function of excrement absorption pads according to the present invention is not limited to human beings, but can also be used for pets such as dogs and cats, and animals such as monkeys. Specifically, it is known that, for example, if you keep a dog or a cat, loving it causes the hormone called oxytocin to be secreted in the brain, which has a sufficient healing effect. And, with the advent of a rapid aging society in recent years, dogs and cats have come to play an important role as important partners of humans.

[0157] However, especially when keeping a dog, the dog must be walked almost every day while it is healthy, and in order to prevent the dog from scattering excrement such as feces and urine during the walk, the dog is often walked wearing a disposable diaper for large dogs or a disposable diaper for small dogs. However, if such a disposable diaper must be changed every day for a long period of time while the dog is healthy, the economic burden on the owner, especially the elderly, will increase considerably. As is clear from these points, by utilizing the present invention, such disposable diapers can be reused as much as possible, and the above-mentioned problem of economic burden can be solved at once.

[0158] This allows even elderly owners to increase the opportunities for their dogs to wear disposable diapers while walking, and eliminates the need to bend down to pick up the feces with a shovel or the like and put it in a plastic bag for absorbing excrement every time the dog defecates during a walk. This allows owners to enjoy walking their dogs without the risk of suddenly hurting their back when their dog stiffens up, or losing their balance and falling and suffering serious injury.

[0159] In addition, many people use disposable diapers equipped with the bag-shaped vinyl sheet of the present invention while walking their dogs, which means that the dogs will no longer urinate on iron public traffic signs, bulletin board posts, telegraph poles, and other supports in order to mark them, thereby preventing unexpected corrosion and resulting damage to these public facilities.

[0160] In the case of monkeys, it goes without saying that the present invention can also be applied to the increasingly number of adorable squirrel monkeys and the like that are sold as pets at pet shops and kept as pets. In Japan, the so-called monkey show has become internationally known and famous as one of the attractions for tourists, and by having the monkeys performing this kind of show wear disposable diapers equipped with the bag-shaped vinyl sheet of the present invention, the amount of disposable diapers that are discarded each time can be drastically reduced, and it becomes possible to have the monkeys perform a performance that pleases the spectators while keeping costs down.

[0161] Furthermore, by making it possible to carry out the simple task of replacing the bag-shaped vinyl sheet according to the present invention, the number of times that the staff performing the monkey show have to change disposable diapers, which is an unnecessary and stressful task, can be drastically reduced, and this can prevent the staff from engaging in acts of animal cruelty, such as releasing stress on the monkeys, which has occasionally become a problem in recent years.

[0162] Furthermore, in the event of a major disaster such as a major earthquake that causes infrastructure such as sewerage to stop functioning, or in the event of a sudden conflict between nations, people will have to spend long periods of time in extremely cramped evacuation centers that either do not have flush toilets or that do not function even if they do.

[0163] In such a case, it is naturally difficult to provide sufficient disposable diapers to serve as a temporary toilet. Therefore, it is necessary to continue to use the disposable diapers provided once over and over again. In this case, by using the bag-shaped vinyl sheet for improving the function of the excrement absorption pad according to the present invention, it is possible to cope with such a special situation and contribute to reducing the physical and mental burden of the evacuees as much as possible.

[0164] It should be noted that the above-described embodiment and the drawings and modified examples based thereon are merely examples of implementing the present invention, and it goes without saying that the shape, dimensions, materials, etc. can be appropriately changed within the scope of the invention in which the effects of the invention can be achieved.

[0165] Specifically, for structures in which an oval or elliptical upper opening is formed, the shape of this upper opening is not limited to this, and any shape is acceptable as long as excrement and waste are collected inside the bag-shaped vinyl sheet without leaking out onto the upper vinyl sheet.

[0166] In an embodiment having this structure, since the upper vinyl sheet itself has an upper opening formed in advance, it can be quickly and easily attached to the excrement (excretion) absorbing pad and then worn on the user's body, making it possible to complete the task of changing the excrement (excretion) absorbing pad or a disposable diaper equipped with an excretion absorbing pad with a simple operation without bothering the care recipient. Also, if the excrement (excretion) absorbing pad is a urinary incontinence pad or a sanitary product (napkin), it can be carried around and quickly changed when going out.

[0167] In addition, in the case of bag-shaped vinyl sheets that form an upper opening, the upper vinyl sheet has a structure in which cutting lines, perforations, or a combination of these for folding are pre-designated, and the upper opening is formed by folding it over; however, as long as the folded portion can be made to adhere evenly to the user's skin so that excrement and waste can be collected inside the bag-shaped vinyl sheet, cutting lines and perforations of various sizes and shapes, and combinations of these, can be appropriately selected.

[0168] In addition, the upper opening in each of the above-mentioned embodiments is depicted in the drawings as being fairly long in the longitudinal direction and fairly wide in the width direction. However, this is merely for the sake of ease of understanding and explanation of the invention, and it goes without saying that it is preferable to appropriately determine and select an optimal size for each specific type of excrement or waste that will not leak outside the bag-shaped vinyl sheet.

[0169] It goes without saying that the form of the bag-shaped vinyl sheet 100, 200, 300, 400 for improving the function of the excrement (discharge) absorption pad according to the first to fourth embodiments can be appropriately selected to have holes that match the shape (length, width) that suits the purpose of use. Also, the object inserted into the bag-shaped vinyl sheet 100, 200, 300, 400 is not limited to toilet paper, tissue paper, cloth, etc., and can be anything that efficiently absorbs excrement and discharge and does not cause extreme physical discomfort to the wearer while wearing it.

[0170] Finally, a modified example common to the above-mentioned embodiments will be described with reference to the drawings. Fig. 18 is an explanatory diagram showing a modified example 500 of the bag-shaped vinyl sheet according to the first embodiment, and Fig. 18(a) and (b) are additional diagrams showing a state in which a large number of small through holes 505 are formed in a matrix shape over a certain area in the lower vinyl sheet 502 of the bag-shaped vinyl sheet 500 of this modified example.

[0171] More specifically, Figure 18(a) shows a modified bag-shaped vinyl sheet 500 of the first embodiment in solid lines, as well as a feces absorption pad 10 to which the modified bag-shaped vinyl sheet 500 of the first embodiment is attached in solid lines on the outside, and a urine absorption pad 20 to be inserted into and accommodated in the modified bag-shaped vinyl sheet 500 of the first embodiment through an upper opening 510 in the modified bag-shaped vinyl sheet 500 in the first embodiment in solid lines on the inside.

[0172] In addition, the two wavy curves 511, 512 drawn in the vertical direction in Figure 18 (a) are cutting lines to omit part of the upper vinyl sheet 501 for the sake of convenience of explanation, and are drawn to make it easier to understand this modified example 500 by omitting the part of the upper vinyl sheet 501 sandwiched between these wavy lines of the bag-shaped vinyl sheet 500 and directly showing the numerous small through holes 505 formed in the lower vinyl sheet 502.

[0175] In addition, the size of the numerous small through holes 505 in Fig. 18(a) and the size of the numerous small through holes 505 in Fig. 18(b) are intentionally made to have different inner diameters from the actual size for the sake of easier understanding of the invention and convenience of explanation. In other words, the size of the area in which the numerous small through holes 505 are formed and the inner diameter of each through hole 505 are merely examples, and can be changed as appropriate depending on the intended use of this modified example (the size of the fecal absorption pad, the gender of the user, etc.).

[0176] Figure 19 is an explanatory diagram showing a modified bag-shaped vinyl sheet 600 according to the second embodiment, and is a drawing additionally showing a state in which a large number of small through holes 605 are formed in a matrix pattern over a certain area in the lower vinyl sheet 602 of this modified bag-shaped vinyl sheet 600 in Figures 19(a) and (b).

[0177] More specifically, Figure 19(a) shows a modified bag-shaped vinyl sheet 600 according to the second embodiment in solid lines, the feces absorption pad 10 to which the modified bag-shaped vinyl sheet 600 according to the second embodiment is attached in solid lines on the outside, and the urine absorption pad 20 to be inserted into the modified bag-shaped vinyl sheet 600 according to the second embodiment through an upper opening 610 and accommodated therein in dashed double-dashed lines.

[0178] In addition, the two wavy curves 631, 632 drawn in the vertical direction in Figure 19 (a) are intended to make it easier to understand this modified example 600 by directly showing the numerous small through holes 605 arranged in a matrix pattern in the lower vinyl sheet 602, omitting a portion of the upper vinyl sheet 601 sandwiched between these wavy lines of the bag-shaped vinyl sheet 600.

[0179] Fig. 19(b) is a cross-sectional view of the configuration shown in Fig. 19(a) cut longitudinally at the widthwise center. In this figure, the urine absorbent pad 20 housed inside the modified bag-shaped vinyl sheet 600 according to the second embodiment is shown by a two-dot chain line, and the modified bag-shaped vinyl sheet 600 according to the second embodiment is shown superimposed on the absorbent surface of the feces absorbent pad 10.

[0180] That is, in Figure 19(b), the feces absorbent pad 10 and the modified bag-shaped vinyl sheet 600 of the second embodiment are all shown in solid lines, with their respective cross-sectional portions shown in hatching, and the urine absorbent pad 20 is shown in dashed line.

[0181] In addition, the size of the numerous small through holes 605 in Fig. 19(a) and the size of the numerous small through holes 605 in Fig. 19(b) are intentionally made to have different inner diameters from the actual size for the sake of ease of understanding the invention and convenience of explanation. In other words, the size of the area in which the numerous small through holes 605 are formed and the inner diameter of each through hole 605 are merely examples, and can be changed as appropriate depending on the intended use of this modified example.

[0182] Fig. 20 is an explanatory diagram showing a modified bag-shaped vinyl sheet 600 according to the second embodiment following Fig. 19. More specifically, Fig. 20(a) is a plan view showing a state in which an upper opening 610 of the modified bag-shaped vinyl sheet 600 according to the second embodiment is formed in a state in which the modified bag-shaped vinyl sheet 600 according to the second embodiment is superimposed on the upper surface of the excrement (discharge) absorbing pad 10 and fixed so as not to shift.

[0183] 20(b) is a cross-sectional view showing the state of FIG. 19(a) cut across the entire lengthwise direction at the widthwise center, showing the urine absorbent pad 20 housed inside through the upper opening 610 of the modified bag-shaped vinyl sheet 600 according to the second embodiment, and the feces absorbent pad 10 with the modified bag-shaped vinyl sheet 600 according to the second embodiment layered on top and fixed to prevent slippage. Note that in FIG. 20(b), the upper opening 610 of the modified bag-shaped vinyl sheet 600 is shown without hatching.

[0184] As can be seen from Figures 19 and 20, the urine absorbent pad 20 is housed inside through an upper opening 610 formed in the bag-shaped vinyl sheet variation 600 according to the second embodiment in Figure 20. However, the configuration shown in Figure 20 may be achieved by forming an upper opening 610 in the bag-shaped vinyl sheet variation 600 according to the second embodiment, housing the urine absorbent pad 20 therein, and attaching the resulting product to the feces absorbent pad 10 and bringing them into close contact with each other.

[0185] Fig. 21 is an explanatory diagram showing a first modified example 700 common to the bag-shaped vinyl sheet according to the third embodiment and the bag-shaped vinyl sheet according to the fourth embodiment. More specifically, Fig. 21(a) shows the first modified example 700 of the bag-shaped vinyl sheet according to the third and fourth embodiments in solid lines, and also shows the urine leakage absorbent pad 30 and sanitary product (napkin) 40 to which the first modified example 700 of the bag-shaped vinyl sheet according to the third and fourth embodiments is attached in solid lines.

[0186] In Fig. 21(a), two wavy curves 721, 722 drawn vertically are intended to make it easier to understand the first modified example 700 by directly showing a large number of small through holes 705 formed in the lower vinyl sheet 702, with a portion of the upper vinyl sheet 701 sandwiched between these wavy lines being omitted. Fig. 21(b) is a cross-sectional view of the configuration shown in Fig. 21(a) cut in the longitudinal direction at the widthwise center. This figure shows the state in which the first modified example 700 of the bag-shaped vinyl sheet according to the third and fourth embodiments is superimposed and attached to the absorbing surface of a urine leakage absorbent pad 30 or a sanitary product (napkin) 40.

[0187] In addition, in Figure 21 (b), the urine leakage absorbent pad 30 and sanitary product (napkin) 40 correspond to the solid line parts at the bottom of the drawing, and the bag-shaped vinyl sheet of the third embodiment and the modified bag-shaped vinyl sheet of the fourth embodiment 700 are also shown with solid lines and cross-sectional parts hatched, with the upper opening 710 shown without hatching.

[0188] In addition, the size of the numerous small through holes 705 in Fig. 21(a) and the size of the numerous small through holes 705 in Fig. 21(b) are intentionally made different from the actual inner diameter dimensions for the sake of ease of understanding the invention and convenience of explanation. In other words, the size of the area in which the numerous small through holes 705 are formed and the inner diameter dimensions of each through hole are merely examples, and can be changed as appropriate depending on the intended use of this modified example 700 (urinary leakage absorbent pad 30 or sanitary product (napkin) 40).

[0189] Fig. 22 is an explanatory diagram showing a second modified example 800 common to the bag-shaped vinyl sheet according to the third embodiment and the bag-shaped vinyl sheet according to the fourth embodiment. More specifically, Fig. 22(a) shows the second modified example 800 of the bag-shaped vinyl sheet according to the third and fourth embodiments in solid lines, and also shows the urine leakage absorbent pad 30 and sanitary product (napkin) 40 to which the second modified example 800 of the bag-shaped vinyl sheet according to the third and fourth embodiments is attached in solid lines.

[0190] Fig. 22(b) is a cross-sectional view of the configuration shown in Fig. 22(a) cut longitudinally at the widthwise center, showing a state in which a second modified example 800 of the bag-shaped vinyl sheet according to the third and fourth embodiments is superimposed and attached to the absorbent surface of a urine leakage absorbent pad 30 or a sanitary product (napkin) 40.

[0191] 22(b) corresponds to the solid line portion at the bottom of the figure for the urine leakage absorbent pad 30 and sanitary product (napkin) 40, and also shows the bag-shaped vinyl sheet according to the third embodiment and the second modified bag-shaped vinyl sheet according to the fourth embodiment with solid lines and hatched cross-sections, with the upper opening 810 shown without hatching. That is, Fig. 22 shows only the bag-shaped vinyl sheet according to the first embodiment and the second modified bag-shaped vinyl sheet according to the second embodiment 800 with the upper opening 810 already formed.

[0192] In addition, the size of the numerous small through holes 805 in Fig. 22(a) and the size of the numerous small through holes 805 in Fig. 22(b) are intentionally made different from the actual inner diameter dimensions for the sake of easy understanding of the invention and convenience of explanation. In other words, the size of the area in which the numerous small through holes 805 are formed and the inner diameter dimensions of each through hole 805 are merely examples, and can be changed as appropriate depending on the intended use of this modified example (the urine leakage absorbent pad 30 or the sanitary product (napkin) 40 and the differences in their sizes).

[0193] As described above, these common modified examples 700, 800 are characterized in that a large number of small through holes 705, 805 are formed in a certain area of ​​the vinyl sheet on the side (hereinafter referred to as the "lower vinyl sheet 702, 802") on which an upper opening is not formed, among the overlapping portions of the bag-shaped vinyl sheet for improving the functionality of the above-mentioned excrement (discharge) absorption pad.

[0194] At least some or all of the numerous small through holes 705, 805 are designed to actively direct the liquid portion of excrement (excrement) into the excrement (excrement) absorption pad 30 (40) which overlaps the entire surface of the lower vinyl sheet when excrement (excrement) begins to accumulate inside the bag-shaped vinyl sheet 700, 800, so that the mainly liquid portion of the excrement (excrement) is gradually absorbed by the excrement (excrement) absorption pad 30 (40).

[0195] As a result, when the amount of excrement (discharge) is large, the liquid portion of the excrement (discharge) that accumulates inside the bag-shaped vinyl sheets 700, 800 and can be absorbed by the excrement (discharge) absorption pads 30 (40) is absorbed within the maximum volume that these pads can absorb, and the remaining portion that has become a certain size of clump and cannot pass through each of the through holes 705, 805 and the so-called slurry portion that cannot be absorbed by the excrement (discharge) absorption pads 30 (40) are left accumulated in the bag-shaped vinyl sheets 700, 800 for improving the function of the excrement (discharge) absorption pads. This makes it possible to more effectively prevent excrement (discharge) from leaking out of the body of the person wearing the excrement (discharge) absorption pads 30 (40).

[0196] It goes without saying that the above-mentioned first and second modified examples have the same effects as the embodiment not having these through holes and the respective modified examples thereof.

[0197] Furthermore, the area in which the numerous through holes 505, 605, 705, 805 disclosed in the above-mentioned first and second modified examples are formed exhibits an even more advantageous effect when the dimensional arrangement relationship of the two allows the bag-shaped vinyl sheet to be superimposed with the central portion of the through-hole formation area of ​​the bag-shaped vinyl sheet positioned in the vicinity thereof within the excrement (excrement) absorption area formed on the overlapping surface of the excrement (excrement) absorption pad on which the bag-shaped vinyl sheet is superimposed.

[0198] Specifically, by overlapping the two in this dimensional arrangement, the liquid portion of the excrement (discharge) seeps into the excrement (discharge) absorption pad through the numerous through-holes and is then evenly diffused and absorbed throughout the surrounding excrement (discharge) absorption pad, thereby achieving the unique effect of maximizing the amount of excrement (discharge) absorbed throughout every corner of the pad without leaking out to the outside of the excrement (discharge) absorption pad.

[0199] In this case, the area of ​​the absorbent surface will vary depending on the type and individual differences of each excrement (excrement) absorption pad, but in common with all of these, when the bag-shaped vinyl sheet is overlaid on the absorbent surface of the pad as described above, it is best to form the bag-shaped vinyl sheet with a width (size) of the through-hole formation area with enough leeway so that the area where the through-hole is formed in the bag-shaped vinyl sheet is surrounded by the absorbent surface of the excrement (excrement) absorption pad in order to maximize its effectiveness.

[0200] The bag-shaped vinyl sheet for improving the functionality of excrement (discharge) absorption pads according to the present invention described above has the remarkable effects described in the above-mentioned embodiments and each of the modified examples, so in order to emphasize this point, we will finally explain this unique effect.

[0201] The bag-shaped vinyl sheet for improving the functionality of excrement (excreta) absorption pads according to the present invention can obviously be produced at very low cost because of its structure, and can be rapidly supplied in large quantities.

[0202] In addition, since it can be folded and stored, it does not take up much space when stored at a nursing care site, and there is no need to reserve special storage space. In addition, in daily life, if you carry a large number of disposable diapers, urine leakage absorption pads, and sanitary products (napkins) with you when you go out to work, shopping, travel, or to meet friends, your luggage will take up a lot of space, but the bag-shaped vinyl sheet for improving the functionality of excrement (excretion) absorption pads according to the present invention does not take up much space even if you fold it and carry multiple sheets. In addition, it is very light in weight, so it is suitable for carrying multiple sheets.

[0203] This allows people who possess the bag-shaped vinyl sheet for improving the function of absorbing excrement (excretion) according to the present invention to avoid having to frequently change costly disposable diapers, urinary absorbing pads, urinary leakage absorbing pads, and sanitary products (napkins) during heavy menstruation, resulting in economic savings and eliminating the need to frequently discard disposable diapers, which are particularly bulky.

[0204] In the above-mentioned first and second embodiments and their respective modifications, the urine absorbent pad is inserted and stored in the bag-shaped vinyl sheet for improving the function of the excrement absorbent pad, but this is not limited to this. Specifically, this is particularly effective when living in evacuation shelters due to a disaster or conflict as described below and supplies are in short supply, but in addition, in the above-mentioned cases of daily life when there is a shortage of urine absorbent sheets or when it is necessary to reduce costs, it is also possible in the present invention to stuff paper towels, toilet paper, handkerchiefs, pieces of cloth, hand towels, etc. into the bag-shaped vinyl sheet instead of the urine absorbent sheet.

[0205] Also, in the third and fourth embodiments and their variations described above, it is also extremely useful to stuff tissue paper, toilet paper, cloth scraps, etc. into a bag-shaped vinyl sheet, and then periodically discard the tissue paper, toilet paper, cloth scraps, etc. when the excrement and waste have soaked into the tissue paper or cloth scraps and replace them with new tissue paper, toilet paper, cloth, etc.

[0206] This allows the bag-shaped vinyl sheet of the third embodiment attached to a urine leakage absorbent pad or the bag-shaped vinyl sheet of the fourth embodiment attached to a sanitary napkin to be worn for a longer period of time together with the object to which it is attached. It also contributes to reducing waste, which is environmentally friendly.

[0207] As is clear from the above explanation, the bag-shaped vinyl sheet for improving the functionality of excrement absorption pads according to the present invention is easy to store and carry, as described above, and can provide a sense of security to a variety of users from various perspectives.

[0208] Furthermore, in reality, it is extremely difficult to store large quantities of and frequently change sanitary products such as disposable diapers, urinary and fecal absorbent pads, urinary incontinence pads, and napkins in preparation for life in evacuation shelters in the event of a disaster such as a major earthquake or a major volcanic eruption, which can occur at any time without warning, or for sudden conflicts to break out between countries as the world situation worsens.

[0209] Therefore, if a large number of bag-shaped vinyl sheets for improving the functionality of excrement (excretion) absorption pads according to the present invention, which are extremely inexpensive and take up little space when folded and stored, are prepared in advance, a limited number of disposable diapers, feces absorption pads, urine leakage absorption pads, napkins, and other sanitary products can be used for as long as possible. This has the unique advantage that disposable diapers, feces absorption pads, urine leakage absorption pads, napkins, and other sanitary products, which are considered to be one of the most important life-related items for evacuees living in evacuation shelters, can be used by many people for as long as possible, even with a small stockpile.

[0210] For example, if disposable diapers, excrement absorbing pads for absorbing urine and urine, incontinence absorbing pads, sanitary napkins, etc. were to be kept in stock in units of, say, hundreds in preparation for the aforementioned sudden major disasters or national-level conflicts, several large cardboard boxes would need to be kept in stock at all times, which would be impossible to keep in a home.Similarly, if several thousand units were to be kept in stock at large-scale government emergency evacuation facilities such as community centers and halls in preparation for the aforementioned major disasters or national-level conflicts, at least dozens, or even hundreds, of cardboard boxes would need to be kept in stock at all times.

[0211] On the other hand, the bag-shaped vinyl sheet according to the present invention only requires stacking the vinyl sheets for storage, so that the storage volume required for the above-mentioned regular storage in a home is at most the equivalent of a few stacked hand towels. Even when the bag-shaped vinyl sheet according to the present invention is constantly stored in a large government evacuation facility for long-term accommodation of refugees, the storage volume required for the storage of a large number of refugees is at most the equivalent of a few cardboard boxes, even if a large number of the bag-shaped vinyl sheet is stored in consideration of the number of refugees. Furthermore, by constantly storing the bag-shaped vinyl sheet according to the present invention in this small storage space, the excellent effect of the present invention can be exerted to significantly improve the poor evacuation life of many refugees, even in the event of the above-mentioned major disaster or national-level conflict, in which infrastructure facilities such as water supply and sewerage completely stop functioning or the logistics system for supplying daily necessities necessary for evacuation completely malfunctions.

[0212] Regarding the method of forming the openings 210, 320, 420, 610, 810, unlike the above-mentioned explanations, instead of folding back each area of ​​the upper vinyl sheet unfolded through the cut portions (211-215, 321-325, 421-425, 621-625, 821-825) further outward from the upper vinyl sheet as in the above-mentioned embodiments and their examples and variations, it is also possible to fold back in the opposite direction, i.e., toward the inside of the bag-shaped vinyl sheet.

[0213] In addition, among the cuts in the upper vinyl sheet unfolded at the above-mentioned cuts, the first cuts 211, 321, 421, 621, 821 extend horizontally in the figure, and the second cuts 212, 213, 322, 323, 422, 423, 622, 623, 822, 823 and the third cuts 14, 215, 324, 325, 424, 425, 624, 625, It is also possible not to fold back 824, 825 up to their tips over the entire area of ​​the upper side (front side) of the upper vinyl sheet or the lower side (back side) of the above-mentioned upper vinyl sheet, which is the inside (inner side) of the above-mentioned bag-shaped vinyl sheet, but to fold back only between a position an appropriate length from each tip and each end 211a, 211b, 321a, 321b, 421a, 421b, 621a, 621b, 821a, 821b of the corresponding first cutout portion.

[0214] This allows the area (size) of the folded-back region to be adjusted as needed by changing the folding position, and as a result, the size of the opening of the bag-shaped vinyl sheet itself can be adjusted to be small or medium as needed.

[0215] In this way, the size relationship of the openings formed can be adjusted on a case-by-case basis so that openings of a size necessary and sufficient to achieve the effects of the present invention are formed according to the application of each absorption target of the V-shaped incisions of the present invention, or according to the wearer's gender, physique, and actual excretion or excretion site.

[0216] In this case, if the cut end of the cut portion is a perforation, the perforation can be continuously cut to the desired position depending on the case, and the most preferable complete cut portion can be created for each case. This allows the most preferable size of the cut portion to be created for each case. In this way, the most preferable size of the opening can be easily formed by subsequent folding back of the vinyl sheet.

[0217] Furthermore, even if the above-mentioned folded portions are folded so as to enter the inside of the bag-shaped vinyl sheet, the folded portions are folded back in a fairly rounded shape due to the elasticity of the upper vinyl sheet itself, just as in the case where the folded portion of the upper vinyl sheet described above is folded back above it and then above it.

[0218] This allows the rounded, elastic part to adhere firmly to the wearer's skin when the wearer presses the rounded folded part against the skin when putting on the garment, and as a result, it is possible to effectively prevent excrement and waste from leaking out of the bag-shaped vinyl sheet, just as in the case where the upper vinyl sheet is folded over to the front.

[0219] Thus, the present invention has the extremely advantageous feature that it allows the size of the opening to be made large, small, or medium, or the location of the opening to be shifted depending on the conditions under which the present invention is used, thereby making it possible to optimize the usage conditions to suit the preferences of the individual who enjoys the benefits of the present invention.

[0220] Furthermore, with regard to each of the folded portions (216-219, 326-329, 426-429, 626-629, 826-829) introduced in the above-mentioned embodiment, examples, and variations, the explanation based on the drawings has it that each of these folded portions has a configuration in which an opening is formed by folding each of these folded portions further upward of the upper vinyl sheet, while the explanation based on text in a different form has it that each of these folded portions has a configuration in which an opening is formed by folding each of these folded portions into the inside of the bag-shaped vinyl sheet.

[0221] In this case, for example, if the size (folded area) of each folded portion is larger than necessary, it may be cut to an optimal size using a cutting tool such as scissors and then superimposed on the excrement absorption pad or the absorbent surface of the excrement absorption pad. By adopting such a method, it is possible to prevent problems, particularly when inserting the folded portions into the inside of the bag-shaped vinyl sheet to form an opening, in which any or all of the folded portions are too large (too wide in area) and it takes time to insert them into the bag-shaped vinyl sheet, or in which the folded portions get caught inside the bag-shaped vinyl sheet, resulting in an excessively bulging bag-shaped vinyl sheet rather than the original almost thin, tight-fitting bag-shaped vinyl sheet.

[0222] Alternatively, instead of using the above-mentioned cutting lines, a cutting tool such as scissors may be used to cut the material at the optimum position and length, which may then be folded back to form the opening, and excess portions of each folded portion may be removed using a cutting tool such as scissors as necessary, before being superimposed on the absorbent surface of the excrement absorption pad or waste absorption pad.

[0223] It should be noted that the bag-shaped vinyl sheets according to the above-mentioned embodiments and examples and modified examples have been described as being worn by the user by overlapping them on the absorbent surface of the above-mentioned excrement absorption pad, waste absorption pad, or excrement absorption pad, but they are not necessarily limited to such usage, and their effects can be fully achieved even through exceptional and limited usage methods.

[0224] Specifically, it is also effective as a measure against urinary leakage during practice or during actual competitions for female athletes who perform floor exercises or gymnastics. In other words, the above-mentioned female athletes may unexpectedly leak urine during practice or during actual competitions due to mental tension or the way they exert their muscles. As mentioned above, this is due to a physiological structural problem in which the length of the female urethra is much shorter than that of the male urethra, and it is said that there are many relatively young female athletes who are potentially suffering from this kind of problem that they cannot easily talk about, even if they are young female athletes.

[0225] For such female athletes, the concerns mentioned above mean that they are unable to concentrate mentally and are unable to perform at their best if they are constantly worried about leaking urine during daily practice or during actual matches and staining their athletic clothing.

[0226] However, using bulky, commercially available incontinence prevention pads during training involving strenuous exercise such as floor exercise or gymnastics should be avoided as it disrupts the usual pace, mental pace, and physical pace of the body's movements, preventing one from performing at their best.

[0227] Therefore, instead of wearing such a urine leakage prevention pad, by simply placing the bag-shaped vinyl sheet of the present invention between the excretion area and the athletic wear during daily practice or during actual competitions, even if urine leakage does occur, traces of such urine leakage will not seep onto the athletic wear, and the athlete can continue with the above practice or take part in the actual competition with the usual sense of ease, without any mental anxiety.

[0228] Moreover, since what is sandwiched between the excretory area and the athletic wear is a single bag-shaped vinyl sheet with an extremely thin thickness, it can be said that it does not interfere with the movement of the body during practice or during competitions and does not have any adverse effects. Also, since the unit price of a single bag-shaped vinyl sheet is very low, it is not too costly to secure a reasonable number of them and continue to use one for each daily practice and subsequent competitions, and in this respect too, it can be said that the bag-shaped vinyl sheet of the present invention itself has an extremely excellent advantage.
