Description

Technical Field

[0001] The present invention relates to a disposable diaper bag type diaper that has a bag for storing feces, can reduce the spread of unpleasant dirt and the emission of bad odor around the anus caused by feces, and can be easily and hygienically worn, removed, and disposed of.

Background Art

[0002] Conventional paper diapers are generally classified into pants type and wrap-around type, and many of them impregnate excrement with a water-absorbing polymer. On the other hand, instead of a water-absorbing polymer, there are inventions such as a method of guiding feces to a storage part by sticking a feces discharge tube to the outer peripheral part of the anus with an adhesive (see Patent Document 1), and a diaper with an excrement storage bag provided with an opening at a position where the genitals and the anus come into contact, and having a feces storage bag and a urine storage bag (see Patent Document 2).

[0003] However, the pants type and wrap-around type diapers have the problem that the wearing and removing operations are troublesome. On the other hand, when using a feces discharge tube or the like, there is a risk of feces backflow, and a sense of discomfort may occur in the buttocks due to the presence of the feces discharge tube during wearing. Furthermore, in the case of a diaper with an excrement storage bag, there are problems such as feces not being successfully taken into the storage bag from the opening and spreading to the buttocks, resulting in unsanitary conditions, and the wearer feeling uncomfortable. In addition, as the super-aging society progresses, the amount of waste paper diapers using a water-absorbing polymer has been increasing year by year, imposing a burden on incineration facilities and the environment.

Mode for Carrying Out the Invention

[0017] Hereinafter, embodiments for carrying out the present invention will be described. Note that these examples are merely examples shown for convenience of explanation, and the present invention is not limited to these examples in any sense.

[0018] FIG. 1 is an overall plan view of the disposable bag-type diaper of the present invention, and mainly includes a bag-shaped main body portion (1) made of a sealed non-water-permeable film, a feces guiding portion (2) formed near the center of the main body portion, and a fixing adhesive portion (3).

[0019] The main body portion (1) has a sealable bag-like structure made of a non-water-permeable film having an inner surface (1a) that touches human skin, an outer surface (1b) on the back side thereof, and a storage portion (1c), and mainly receives and stores feces.

[0020] As for the material, polyethylene, polypropylene, and other polymer materials can be preferably used, but materials that can be naturally decomposed, such as water-repellent treated paper and biodegradable plastics, can also be utilized.

[0021] When the wearer is a carrier of infectious bacteria and requires sanitary management of dangerous excrement, the entire main body part (1) can be specially colored or marked with handling precautions to prevent safety issues and misidentification during final disposal after use.

[0022] The outer contour shape of the main body part (1) is most easily available in a rectangular shape, and it is suitable because there is no waste loss generated during production.

[0023] Since the amount of defecation per adult per time is about 1 to 2 normal-sized bananas, the volume of the main body part (1) is set to about 200 cc to 450 cc. In the case of a rectangular plastic film bag, the outer dimensions are approximately 300 mm in length and 230 mm in width as a guide, and can be made smaller or larger according to the defecation amount based on the wearer's physique and diet, and various care urgency situations.

[0024] The inner surface (1a) is the surface that directly contacts the human body and skin. A feces guiding part (2) is installed in the central part, and fixing adhesive parts (3) are installed in the upper and side parts. The other parts are covered with a top sheet (6) with low skin irritation to improve comfort and touch, and reduce the burden on the skin.

[0025] The outer surface (1b) is the back side of the inner surface (1a). At the central part, at the position where the feces guiding part (2) of the inner surface (1a) is formed, a center mark (9) corresponding to the position of the feces guiding linear cut (5) or the feces guiding hole (5') within the adhesive surface (4) is displayed. By using this as a mark during wearing, the feces guiding part (2) can be accurately aligned with the wearer's anus and pasted.

[0026] Figure 3 shows the bottom view of the bag-type diaper according to the present invention. By aligning a finger with the center mark (9) and pressing it, the guiding portion (2) can be accurately attached to the anal region. Figure 10 shows the alignment state of the anus and the guiding portion (2) when the bag-type diaper of the present invention is worn by the wearer.

[0027] The guiding portion (2) is installed at the central portion of the inner surface (1a) of the main body portion (1), has an adhesive surface (4) on the inner surface (1a), and a guiding linear cut (5) or a guiding hole (5') formed so as to penetrate the inner surface (1a) of the main body portion (1) from the adhesive surface (4), and a pickup portion (7) located on the outer periphery of the adhesive surface (4) for facilitating peeling of the adhesive surface from the skin of the wearer after use of the bag-type diaper.

[0028] The guiding portion (2) is installed near the central portion of the inner surface (1a) of the main body portion (1), and its position is most preferably at the central position that is approximately divided into two both vertically and horizontally of the entire bag-type diaper of the present invention, considering the correspondence to the position of the anus for defecation and the slight positional deviation during and after wearing the bag-type diaper.

[0029] The guiding portion (2) functions as an opening for guiding feces to the main body portion (1) when the wearer of the bag-type diaper of the present invention defecates, and as a blocking portion for preventing the backflow of feces when defecation is completed.

[0030] Therefore, the guiding portion (2) is attached to the anal and and the gluteal cleft portion with the adhesive surface (4). During defecation, the guiding linear cut (5) or the guiding hole (5') opens following the shape of the anus, and feces are guided into the bag, which is the accommodating portion (1c) of the main body portion (1), through the guiding linear cut (5) or the guiding hole (5') opened by the passing pressure of defecation. When defecation is completed, the guiding linear cut (5) or the guiding hole (5') closes following the shape of the anus, preventing the backflow and spread of feces in the accommodating portion (1c) (or the bag) to the buttocks.

[0031] As described above, the feces guiding part (2) has a structure that opens and closes following the shape of the opening and closing movement of the anal part only during defecation. Since the dirt on the anal part is basically only the opening gap of the feces guiding linear incision (5) or the feces guiding hole (5'), the dirt on the buttocks is very little, which simplifies the care work.

[0032] FIG. 9 is a diagram showing the opening and closing operation following the movement of the anus of such a feces guiding part (2).

[0033] (o) shows a state in which the bag-type diaper of the present invention is worn together with the hip line (11) and anus of the wearer. At this time, the feces guiding linear incision (5) or the feces guiding hole (5') is closed.

[0034] Next, (p) shows the state at the initial stage of the wearer's defecation start. At this time, feces start to come out, and the feces guiding linear incision (5) or the feces guiding hole (5') opens slightly following the opening of the wearer's anus.

[0035] Subsequently, (q) shows the state during the wearer's defecation. At this time, feces are continuously discharged, the opening of the wearer's anus is maximized, and the opening of the feces guiding linear incision (5) or the feces guiding hole (5') also becomes larger.

[0036] Finally, (r) shows the state after the wearer's defecation is completed. At this time, the feces guiding linear incision (5) or the feces guiding hole (5') closes as it was originally following the movement of the anus closing.

[0037] The above operation of the feces guiding linear incision (5) or the feces guiding hole (5') following the opening and closing of the anus is due to the fact that the feces guiding part (2) of the present invention is designed to be attached to the wearer's anus in particular with the adhesive surface (4).

[0038] The adhesive surface (4) is formed by laminating an adhesive on a base material made of a non-permeable film or an elastomer film. The same non-permeable film as that of the main body (1) can be used. As the elastomer film, those formed by molding stretchable natural or synthetic rubber into a sheet or film shape can be used, and in particular, natural rubber latex, aqueous or solvent-based polyurethane, polyisoprene, etc. that are excellent in stretchability, tensile strength, safety, etc. can be preferably used.

[0039] It is desirable that the adhesive part of the adhesive surface (4) is the entire adhesive surface. However, as long as it can follow the movement of the anus from the start to the end of the wearer's defecation, or can prevent the spread and contamination of feces around the anus during or after defecation, it does not necessarily have to be a part of the entire adhesive surface. For example, the center position of the feces guiding linear cut (5) or the vicinity of the pickup part (7) can be made non-adhesive.

[0040] The feces guiding linear cut (5) or the feces guiding hole (5') serves to guide the feces to the accommodating part (1c) of the main body (1) of defecation and prevent the spread of feces to the buttocks.

[0041] Of course, the feces guiding linear cut (5) and the feces guiding hole (5') can be used in combination. For example, the feces guiding linear cut (5) can be provided on the outer periphery of the feces guiding hole (5').

[0042] Examples of specific forms of the feces guiding linear cut (5) are shown in (h) to (m) of FIG. 8. That is, it has an X shape, a radial linear cut based on this, a cross shape, or a transverse line based on this and has a plurality of linear cuts. Among these, in particular, those without a vertical cut line like the X shape are preferable for reducing the spread of feces to the buttocks, genitals, and their surroundings during defecation.

[0043] Also, in the case of X-shaped or cross-shaped linear cuts where the cut line of the feces guiding linear cut (5) radiates from its central part or linear cuts based on them (such as h, i, j), a cut piece with a sharp shape at a right angle or acute angle is formed at the central part of the adhesive surface (4), and if this pierces the wearer's anus, the wearer may feel pain. In such a case, as shown in (k) or (l), by appropriately removing the sharp tip of the cut piece, for example, into a small or large circular shape or polygonal shape, it is possible to avoid inconveniences such as feeling such pain.

[0044] On the one hand, by pre-drilling a circular or polygonal hole in the central part of the feces guiding linear cut (5), the usability of the wearer can be improved and defecation can be made easier. In addition, it is possible to reduce the soiling of the vicinity of the central part of the feces guiding linear cut (5) due to defecation. When pre-drilling a hole in the central part of the feces guiding linear cut (5) in this way, when removing the bag-type diaper after use, measures such as cleaning and wiping the vicinity of the wearer's anus are required. However, even when such a hole is not provided, almost the same measures are required, and it can be said that it is not a very inconvenient thing.

[0045] Also, it is possible to use the feces guiding linear cut (5) extended to receive urine. However, if necessary, measures such as shaving the body hair around the genitals or putting a water-absorbing polymer or coagulant into the accommodating part (1c) of the main body part (1) and using them in combination are required to prevent urine from leaking outside the diaper.

[0046] An example of a specific form of the feces guiding hole (5') is shown in (n) of FIG. 8. The feces guiding hole (5') is arranged almost at the center of the adhesive surface (4) and has an opening in a circular, elliptical or polygonal shape.

[0047] Although the entire adhesive surface (4) can be made of an elastomeric film substrate, only a part of the central portion of the adhesive surface (4) can also be made of an elastomeric film substrate. In either case, the elastomeric film substrate is fixed to a water-impermeable film that is cut out and opened in accordance with the shape, size of the entire defecation guiding portion (2), or a part of the center of the defecation guiding portion (2) on the inner surface (1a) of the main body portion (1) by an adhesive or a heat-sealing process, so as to determine the position of the defecation hole (5‘) and install it.

[0048] The size and shape of the defecation guiding portion (2) can be freely determined within a range that fits near the central portion inside the inner surface (1a) of the main body portion (1). First, in order to surely guide defecation to the accommodating portion (1c) of the main body portion (1) and not stain the wearer's buttocks, and then considering the usability when worn on the wearer's buttocks or anus, as well as the convenience of installing the fixing adhesive portion (3) and the top sheet (6), etc., it is necessary to set it to an optimal range and shape.

[0049] As an example, as shown in Fig. 8(h), the vertical and horizontal dimensions are respectively about 100 mm to about 120 mm and about 70 mm to about 90 mm, and as the shape, a vertically long rectangle or an ellipse is desirable.

[0050] Also, the size of the defecation linear cut (5) is designed based on the case where the wearer's anus is maximally opened. As an example, as also shown in Fig. 8(h), assuming the maximum diameter of the feces is about 35 mm, the vertical and horizontal lengths are preferably about 40 mm and about 35 mm respectively.

[0051] Furthermore, the diameter of the opening portion of the defecation hole (5‘) depends on the stretchability of the elastomeric film of the substrate. However, since the maximum diameter of the feces is about 35 mm, it is desirable that it be less than that, and it is more desirable to be even smaller in order to reduce the spread of feces to the anus and its surroundings. Specifically, it is preferable that the diameter of the opening portion is about 30 mm or less, more preferably about 20 mm or less, and even more preferably about 15 mm or less.

[0052] The fixing adhesive part (3) serves to fix the bag - type diaper of the present invention by sticking it to the lower back near the wearer's buttocks or coccyx. As shown in FIG. 7, at least one fixing adhesive part (3) is installed on the inner surface (1a) around the urine - guiding part (2), on the outer side of the outer edge of the inner surface (1a), or both. In order to enhance the certainty and fixing force of fixing to the wearer's body, it is desirable to install a plurality of them.

[0053] When installing the fixing adhesive part (3) only on the inner surface (1a) around the urine - guiding part (2), it is advisable to install it continuously or in a plurality of divided locations on the left - right or upper part of the urine - guiding part (2).

[0054] When installing the fixing adhesive part (3) on the outer side of the outer edge of the inner surface (1a), utilize the outer surface (1b) of the main body part (1), and stick a single - sided adhesive tape so that it partially protrudes outward from the inner surface (1a) of the main body part (1). In this case, it is advisable to install it continuously or in a plurality of divided locations on the left - right or upper part so as to surround the inner surface (1a) of the main body part (1).

[0055] On the other hand, at the time of disposal after use, as shown in FIG. 5, when the diaper is folded from the center of the inner surface (1a) and the fixing adhesive parts (3) are bonded together, the urine - guiding part (2) of the diaper is further or doubly sealed to form a bag - like shape enclosing feces, which is convenient for disposal.

[0056] The fixing adhesive part (3) can be formed by applying an adhesive to the inner surface (1a) of the main body part (1), sticking a double - sided adhesive tape to the inner surface (1a), or sticking a single - sided adhesive tape to the outer surface (1b). In addition, according to the build of the wearer, etc., as shown in FIG. 7, the forming position, shape, and area can be appropriately changed.

[0057] Examples of the materials and adhesives used in each part of the adhesive surface (4) or the fixing adhesive part (5) of the present invention include, but are not limited to, urethane gel, rubber - based adhesives, acrylic - based adhesives, silicone - based adhesives, and hydrocolloids.

[0058] The topsheet (6) covers the portion of the inner surface (1a) that directly contacts the skin, excluding the urine guiding portion (2) and the fixing adhesive portion (5), has low irritation to the skin, and has liquid permeability such as water, improving the comfort of the wearer.

[0059] Examples of the material for such a topsheet (6) include non-woven fabric, woven fabric, mesh sheet, paper, and plastic film formed with liquid permeation holes. Examples of the constituent material of the fiber for forming the non-woven fabric or woven fabric of the topsheet material include polyolefin, polyester, nylon, cellulose, rayon, and cotton. Examples of polyolefin include polypropylene and polyethylene. Examples of polyester include polyethylene terephthalate (PET) and polybutylene terephthalate. Further, the fiber for forming the non-woven fabric or woven fabric of the topsheet material is preferably a hydrophilic fiber or a hydrophobic fiber whose surface is hydrophilized by surface treatment with a surfactant.

[0060] The pickup portion (7) abuts on the outer periphery of the adhesive surface (4) of the urine guiding portion (2) with a predetermined width in a non-adhesive state against the main body portion (1). The pickup portion (7) is not coated with an adhesive, and when the bag-type diaper of the present invention is removed after use, the urine guiding portion (2) can be easily peeled off from the wearer's body from this pickup portion (7). This prevents the wearer's skin from being easily damaged when the adhesive surface (4) is forcibly peeled off with a fingertip or the like.

[0061] The pickup part (7) is made of a flexible material. Examples of the flexible material for the pickup part (7) include paper materials, rubber-based materials, sponge materials, and resin materials other than these. As the paper material, those having a certain degree of flexibility and water resistance can be preferably used. Examples of the rubber-based materials include silicone rubber, chloroprene rubber, urethane rubber, and ethylene propylene rubber. Examples of the sponge materials include cellulose sponge, polyurethane sponge, and melamine sponge. Examples of the resin materials include silicone resin, polyurethane resin, and soft vinyl chloride.

[0062] The pickup part (7) needs to have a predetermined width and thickness. The width may be about 2 mm to about 5 mm, and a width of about 3 mm is preferable. As for the thickness, it is better to be as thin as possible so that the wearer does not feel discomfort when wearing. The shape of the pickup part (7) may be continuous or discontinuous, and the width may or may not be constant. It is important to devise it so that the guiding part (2) can be peeled off as easily as possible.

[0063] The release paper (8) covers the adhesive surface (4) and the surface of the fixing adhesive part (5) when storing the bag-type diaper of the present invention, and plays a role in preventing the deterioration and adhesion of dirt on the adhesive surface and the adhesive part. When in use, it is peeled off and attached or fixed to the wearer's body.

[0064] The string or belt-like body (10) is attached to the outer peripheral part of the main body part (1) as needed to additionally fix the bag-type diaper of the present invention to the wearer's body, and plays a role in preventing the diaper from shifting or partially peeling off when the wearer wearing the bag-type diaper moves the body.

[0065] The string or belt-like body (10) can bind the respective free ends together, form an adhesive part at the free ends and attach and fix them to each other or to the wearer's body, or use the free ends as a hook-and-loop fastener (pile and hook) and overlap and fix them to each other.

[0066] The bag-type diaper of the present invention can be manufactured relatively easily by installing or forming a feces guiding portion (2), a fixing adhesive portion (3), and a top sheet (6) of the skin contact portion on the inner surface (1a) of the main body portion (1).

[0067] In this case, there is a method of manufacturing by attaching the feces guiding portion (2), the fixing adhesive portion (3), and the top sheet (6) prepared separately in advance to a predetermined position of the main body portion (1).

[0068] As another manufacturing method, first, an adhesive is applied in advance to the entire inner surface (1a) of the main body portion (1), then the top sheet (6) cut into the shape of the portion directly touching the human skin is pasted, and then the pickup portion for the feces guiding portion (2), the release paper for the adhesive surface of the feces guiding portion (2), and the fixing adhesive portion are adhesively fixed to predetermined positions respectively, so that it can be manufactured even more easily. That is, in the case of this manufacturing method, the adhesive applied to the entire inner surface (1a) in advance can be used as the adhesive surface (4) of the feces guiding portion (2) and the fixing adhesive portion (3).

[0069] The method of using the bag-type diaper of the present invention is characterized in that, in particular, the feces guiding linear cut (5) or the feces guiding hole (5') of the feces guiding portion (2) is brought into contact with the anus of the wearer, and the adhesive surface (4) is adhered to the buttock crack portion including the anus of the wearer.

[0070] By attaching it to the wearer in this way, the feces guiding linear cut (5) or the feces guiding hole (5') of the feces guiding portion (2) can be opened and closed following the opening and closing of the anus during defecation of the wearer.

[0071] As an example of the usage method related to the actual wearing of the bag-type diaper of the present invention, first, peel off the release paper (8) on the adhesive surface (4) of the feces guiding part (2), and then make the inner surface (1a) abut against the wearer's body from the buttocks to the natal cleft. Next, using the center mark (9) on the outer surface (1b) of the main body part as a guide, press the feces guiding linear cut (5) or the feces guiding hole (5') of the feces guiding part (2) against the wearer's anus with a finger, and stick the adhesive surface (4) of the feces guiding part (2) to the natal cleft including the wearer's anus. Then, peel off the release paper (8) of the fixing adhesive part (3) and stick and fix it to the lower back around the wearer's buttocks and coccyx. Further, if necessary, fix it to the wearer's body using an auxiliary fixing string or belt-like body (10).

[0072] After use, for the bag-type diaper of the present invention, first, peel off or untie the fixing adhesive part (3) and the auxiliary fixing string or belt-like body (10), etc., and then use the pickup part (7) of the feces guiding part (2) to peel off the adhesive surface (4) of the feces guiding part (2) from the natal cleft including the wearer's anus. Then, for disposal, fold the feces guiding part (2) along the center on the left and right as shown in FIG. 4, stick it together and seal it. Thereby, it can fulfill combined and hygienic functions such as preventing leakage of dirt in the main body part (1), preventing associated bacteria release, and reducing the emission of bad odors.

[0073] Furthermore, by folding and sticking together the fixing adhesive parts (3) around the periphery such as the left and right and upper parts of the feces guiding part (2) so that they face each other, the hygiene and safety during disposal after using the diaper can be improved.

[0074] Note that although the present invention has mainly been described centering on the excretion treatment of feces, it can also be applied to the excretion treatment of urine. However, since urine is a liquid, there is a risk that leakage cannot be fully prevented. In such a case, similar to the above-mentioned, by shaving the body hair of the wearer to make it easier to stick and fix the adhesive surface (4) of the feces guiding part (2) and the fixing adhesive part (3), or by putting a water-absorbing polymer, urine coagulant, etc. in the accommodating part (1c) of the main body part (1), improvement can be achieved.

[0075] Examples of the constituent materials of the water-absorbing polymer and the urine coagulant include, for example, polyacrylic acid-based resins, polyaspartic acid-based resins, and cellulose-based resins.

Industrial Applicability

[0076] The bag-type diaper of the present invention reduces the discomfort during use by the wearer, reduces the workload of the caregiver such as the handling of diaper replacement, and reduces the burden of work. Moreover, it can reduce the emission of bacteria and bad odors. Furthermore, since it does not use a water-absorbing polymer, it can reduce the total amount of waste discarded as garbage after use and also contribute to reducing the environmental load. In addition, the bag-type diaper of the present invention can be manufactured inexpensively and easily, and since its own volume is small, it also requires less space in the storage yard and transportation cost.
