<P>PROBLEM TO BE SOLVED: To provide a fecal matter adhesion prevention sheet capable of inhibiting the solid of fecal matter from adhering to a toilet bowl and being disposed of easily. <P>SOLUTION: A first sheet body 2 with high waterproofness and a second sheet body 3 with low waterproofness are laminated. Hence the fecal matter adhesion prevention sheet 1 is not easily dispersed because of the high waterproofness of the first sheet body 2 even if liquid adheres thereto. Therefore, by reserving water in a portable toilet, etc. and putting the sheet 1 thereon before excretion, the solid of the fecal matter is received to avoid adhesion of the solid of the fecal matter to the portable toilet. Furthermore, even if the sheet with the fecal matter is thrown into the toilet bowl of a flush toilet from the portable toilet, the first sheet body 2 can also be dispersed by external force applied by a water flow in the toilet bowl of the toilet and can be discharged without clogging pipes or causing other troubles. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a sheet for preventing solid matter of excrement from adhering to a toilet bowl.

  For example, a handicapped person, such as a physically handicapped person, has difficulty in moving to a toilet, and therefore a portable toilet that can be installed in a bedroom or the like is used. This portable toilet has a portable container for receiving excrement, and is configured to be able to carry the container to the toilet after use and dispose of the excrement in a flush toilet. When using such a portable toilet, if the excreta solid matter adheres to the container, it will take time for post-processing, so store water in the container in advance, lay toilet paper, tissue, etc. I try to excrete.

Further, a stool collection sheet for receiving stool for collecting a sample from the excreted stool floated in a puddle portion of a flush toilet is known. In the stool receiving sheet for stool collection, the surface of the water-soluble paper is water-resistant treated with water-resistant ink or water-resistant resin. (For example, see Patent Document 1)
A stool collection temporary sheet used for the same purpose as the stool collection sheet is also known. This stool collection temporary sheet is formed by laminating water-dispersible paper on a film made of polyvinyl alcohol or the like. (For example, see Patent Document 2)

JP-A-10-68726 JP-A-10-227787

  Toilet paper is used in flush-type toilets, and is configured to easily separate and disperse fibers when water adheres, so that it can flow from toilet bowls together with excrement through piping. ing. Therefore, even if it is used for the purpose of preventing adherence of the solid matter of the excrement as described above, it is broken and dispersed by the load of the solid matter of the excrement, so that the solid matter is received and prevented from adhering to the container. I can't.

  Tissue has a structure that makes it difficult for fibers to separate from each other even if water adheres to it, and it can receive excrement and prevent it from adhering to the container, but it is discarded and flushed with excrement in a flush toilet. If this happens, troubles such as clogging of the piping will occur, so it cannot be disposed of in a flush toilet.

  The sheets of Patent Documents 1 and 2 are sheets for collecting a part of the stool, the purpose of which is different, and are not sheets that can prevent the solid matter of excrement from adhering to the container of the portable toilet .

  The objective of this invention is providing the excrement adhesion prevention sheet which can prevent the solid of excrement adhering to a toilet bowl, and an easy disposal process.

The present invention is a sheet for preventing the solid matter of excrement from adhering to the toilet,
A first sheet body with high water resistance;
An excrement adherence prevention sheet comprising a second sheet body having low water resistance laminated on the first sheet body.

  According to this invention, the 1st sheet body with high water resistance and the 2nd sheet body with low water resistance are laminated | stacked. As a result, the excrement adherence-preventing sheet is not easily dispersed even if liquid adheres due to the high water resistance of the first sheet body. The solid matter of excrement can be prevented from adhering to the toilet. Furthermore, when flowing together with excrement from a flush toilet or the like, the first sheet body is also dispersed by an external force such as the water flow, and troubles such as clogging of piping do not occur.

  The present invention is characterized in that a deodorant is attached to at least one of the first sheet body and the second sheet body.

  According to the present invention, since the deodorant is attached, the odor generated from the excrement can be suppressed.

  According to the present invention, since the excreta solid matter does not adhere to the toilet bowl, post-treatment such as washing the toilet bowl after use can be facilitated. Further, the excrement adherence prevention sheet can be discarded and flushed together with the excrement in a flush toilet, so that the excrement adherence prevention sheet that becomes filth can be easily discarded and is hygienic.

  Moreover, according to this invention, since the odor which generate | occur | produces from excrement can be suppressed with the excrement adhesion prevention sheet, the surrounding environment deterioration can be suppressed.

  FIG. 1 is a cross-sectional view showing a part of the excrement adherence prevention sheet 1 according to an embodiment of the present invention in a simplified manner so as to facilitate understanding of the laminated structure. FIG. 2 is a perspective view schematically showing the excrement adherence prevention sheet 1 as a whole. FIG. 1 shows a laminated structure ignoring a detailed shape. The excrement adherence prevention sheet 1 is used for preventing the solid matter of excrement from adhering to the toilet bowl during excretion. The excrement adhesion preventing sheet 1 has a thickness dimension T of, for example, 1 mm, a rectangular shape perpendicular to the thickness direction, a length L1 on one side of 10 to 45 cm, and a length L2 on the other side. It is a rectangular parallelepiped sheet which is 10-45 cm.

  The excrement adhesion preventing sheet 1 includes a first sheet body 2 having high water resistance and a second sheet body 3 having low water resistance laminated on the first sheet body 2. A deodorant is attached to one or both of the first sheet body 2 and the second sheet body 3. In the present embodiment, a deodorant is applied to the surface of the second sheet 3 opposite to the first sheet 2 to form the deodorant layer 4.

The 1st and 2nd sheet | seat bodies 2 and 3 are formed and comprised by the sheet form by the fiber which consists of cellulose mutually latching. The first sheet body 2 has a basis weight of, for example, 17 g / m ² . The water resistance of the first sheet body 2 is relatively high. For example, when measured by the Japanese Industrial Standards, specifically the toilet paper loosening test method defined in JIS P4501, it exceeds 100 seconds and is within a range of 300 seconds or less. is there. The second sheet body 3 has a basis weight of 20 g / m ² , for example. The water resistance of the second sheet body 3 is relatively low, and is, for example, in the range of 20 seconds to 100 seconds as measured by the toilet paper loosening test method.

  Water resistance is dispersibility with respect to liquid, and when liquids including water, chemicals, urine, etc. are attached, it is easy to disperse when fibers separate and disperse each other, in other words, easy to loosen. is there. The first and second sheet bodies 2 and 3 adjust the additive amount (including 0) of the agent for adjusting the water resistance, the fiber length, the degree of fiber fibrillation, the fiber thickness, and the like. Thus, the water resistance as described above is obtained.

  The deodorant layer 4 is configured by using a chemical that suppresses ammonia odor as a deodorant and applying the chemical. The chemical | medical agent which suppresses an ammonia odor is implement | achieved by the chemical | medical agent containing the bacteria which decomposes | disassembles ammonia.

  FIG. 3 is a cross-sectional view showing a part of the excrement adherence prevention sheet 1 in a simplified manner so that the shape can be easily understood. The excrement adherence prevention sheet 1 has a convex portion (hereinafter referred to as “mountain portion”) 5 and a concave portion (hereinafter referred to as “valley portion”) 6 with respect to one side in the thickness direction. One of them is formed in a lattice pattern, in other words, they are perpendicular to the thickness direction and alternately arranged in directions perpendicular to each other. The peak portion 5 is a portion protruding in the thickness direction, for example, the first sheet body 2 side, and the trough portion 6 is a portion protruding in the other thickness direction, for example, the second sheet body 3 side. These peaks 5 and valleys 6 are connected by an intermediate portion 7. Thus, the unevenness | corrugation which the excrement adhesion prevention sheet 1 has is a shape in which the rhombus convex part or recessed part with a side of 3 mm is located in a line, and depth (thickness direction dimension) is 1 mm.

  The thicknesses T5 and T6 of each peak portion 5 and each valley portion 6 are smaller than the thickness T7 of the intermediate portion 7. Here, each thickness T5-T7 does not mean the dimension of the thickness direction of the excrement adherence sheet 1, but is the true thickness of each part 5-7. The thickness dimension T of the excrement adherent sheet 1 is a distance in the thickness direction between the peak portion 5 and the valley portion 6 and is substantially the same (1 mm) as the depth of the unevenness.

  FIG. 4 is a front view schematically showing the embossing apparatus 10 constituting a part of the production facility for the excrement adherence prevention sheet 1 in a simplified manner. FIG. 5 is a perspective view showing the embossing roller 11 provided in the embossing apparatus 10. The embossing device 10 is provided so as to be rotatable around its axis L11 in a state where a pair of embossing rollers 11 are elastically contacted. Each embossing roller 11 is made of metal, and has a substantially cylindrical outer peripheral surface formed in an uneven shape in which convex portions and concave portions are alternately arranged in two different directions, for example, in the axial direction and the circumferential direction. . Further, the embossing device 10 includes a heating unit 12 that heats each embossing roller 11.

  The embossing apparatus 10 is conveyed in a state where the first and second sheet bodies 2 and 3 are laminated. The first and second sheet bodies 2 and 3 are passed in the conveying direction A between the embossed rollers 11 that are rotationally driven. At this time, the first and second sheet bodies 2 and 3 are heated and pressurized, and the first and second sheet bodies 2 and 3 are integrated, specifically, bonded and integrated by hydrogen bonding, The uneven excrement adherence prevention sheet 1 having the mountain part 5, the valley part 6 and the intermediate part 7 is formed.

  The pressure applied to the first and second sheet bodies 2 and 3 by the embossing roller 11 is partially different. Due to the difference in pressure, as shown in FIG. 3, the excrement adherence prevention sheet 1 having different thicknesses is formed at the peak part 5, the valley part 6, and the intermediate part 7. The thin portions 5 and 6 have low mechanical strength, and when such a portion is formed, when an external force is applied, the perforations are transmitted through this portion. Prone to cracking.

  The deodorant layer 4 may be applied and formed on the second sheet body 3 before such embossing, or may be applied and formed on the second sheet body 3 after embossing.

  The water resistance of the excrement adherence prevention sheet 1 formed by laminating the first and second sheet bodies 2 and 3 having water resistance as described above and being embossed and joined is determined by the above-mentioned JIS toilet paper loosening. When measured by the test method, it is, for example, around 110 to 130 seconds. Such excrement adhesion preventing sheet 1 is suppressed in dispersion when it is in a still liquid and a slow flow liquid, and is promoted when it is in a rapid flow liquid. The dispersion in the rapid flow liquid is different from the dispersion in which the fibers are separated from each other when the second sheet 3 is attached to the liquid, and the embossing reduces the thickness and decreases the mechanical strength such as tension. In the peak part 5 and the valley part 6 which are carrying out, it is disperse | distributed by producing the crack by external force. Still liquid is a liquid stored in a container, etc., and a slow flow liquid is a liquid that flows down at a flow rate when water in the container flows out when the container is tilted by manual operation. It is a liquid that flows down at about the flow rate of the wash water that passes through the toilet bowl from a tank in a flush toilet.

  Moreover, even if the excrement adherence prevention sheet 1 is suspended in a liquid and the excrement of solid matter in excretion excreted at one time by an adult is mounted, the sheet 1 itself is dispersed by the load. It has a strength not to be damaged.

  FIG. 6 is a cross-sectional view showing the portable toilet 15. FIG. 7 is a perspective view showing the portable toilet 15. The portable toilet 15 is a simple toilet. For example, it is difficult for a physically handicapped person such as a disabled person (hereinafter referred to as a “user”) to move to a toilet after giving his / her convenience, so the portable toilet 15 is installed in a bedroom or the like. It is done. The portable toilet 15 is a portable container that can be seated by a user and is provided facing the opening 17 of the main body 16 that is formed with the opening 17 and can be detached from the main body 16 and carried. 18.

  The excrement adherence prevention sheet 1 is used to prevent the solid matter of excrement from adhering to the toilet bowl, specifically to the container 18 when the portable toilet 15 which is such a simple toilet is used. It is done. Depending on the size of the container 18 and the like, the container 18 is provided with a liquid 19 that is water mixed with about 2 liters of water or a chemical solution such as a disinfectant so that the depth is about 5 to 6 cm. The excrement adherence prevention sheet 1 is provided so as to be spread and spread so as to be stored and placed on the liquid surface of the liquid 19.

  The liquid 19 may be stored in advance, but the excrement adherence prevention sheet 1 is preferably provided immediately before excretion in order to prevent dispersion in the portable toilet 15. Moreover, the excrement adherence prevention sheet 1 is provided so that the second sheet 3 is disposed below. In such a state, it excretes on the excrement adhesion preventing sheet 1.

  FIG. 8 is a cross-sectional view showing a mechanism for preventing adhesion of the solid matter 20 of excrement. FIG. 8 (1) shows the state before excretion, and FIG. 8 (2) shows the state after excretion. When the excrement adherence prevention sheet 1 is provided so as to be placed on the liquid 19 by adjusting the material and the thickness of the fiber, the excrement adherence prevention sheet 1 penetrates the excrement adherence prevention sheet 1 and gradually settles. The The sedimentation speed is small, and when the user excretes, a liquid layer is formed on the excrement adherence prevention sheet 1 as shown in FIG. It will be in a floating state. In this state, when the excrement is excreted by the user, the portion on which the excrement solid 20 is mounted may sink compared to the remaining portion, and the excrement adhesion preventing sheet may wrap up the solid 20. it can.

  As shown in FIG. 8 (1), since the excrement adherence preventing sheet 1 is provided in a state where a liquid layer is formed thereon, when excrement comes into contact with the excrement adherence preventing sheet 1 Can be mitigated by the liquid layer on the excrement adherence prevention sheet 1, and dispersion of the excrement adherence prevention sheet 1, specifically, dispersion of the first sheet body 2 can be suppressed. Moreover, when the solid matter 20 of excrement is mounted, as shown in FIG. 8 (2), the energy based on the load of the solid matter 20 is absorbed as energy for the second sheet body 3 to disperse, Only the two-sheet body 3 is dispersed to prevent the first sheet body 2 from being dispersed. In this way, the excrement adherence prevention sheet 1 as a whole can be prevented from being dispersed and the solid matter 20 can be wrapped and held, and adhesion to the container 18 can be prevented.

  In this state, the solid matter 20 is held by the excrement adherence prevention sheet 1, and the container 18 is transported to a flush toilet or the like, and the solid matter 20 is retained in the excrement adherence prevention sheet 1. By discarding the excrement adherence prevention sheet 1 together with the liquid 19 in the toilet bowl, it is possible to prevent the solid matter 20 from adhering to the container 18 and discard the excrement in the toilet. Thereafter, the waste can be flowed and processed by flowing water into the toilet bowl. At this time, the excrement adherence prevention sheet 1 is used in the mountain part 5 and the valley part 6 where the strength is partially reduced by embossing as described above by the force of water flowing down the toilet bowl. By being divided, it is dispersed and discharged from the toilet without being clogged in the piping.

  According to the present embodiment as described above, the excrement adherence prevention sheet 1 is easily dispersed in a still liquid and a slow flow liquid even if liquid adheres due to the high water resistance of the first sheet body 2. It will never be done. Therefore, in a state where the liquid 19 is stored in the portable toilet 15 or the like, the excrement adherence prevention sheet 1 is provided so as to spread on the portable toilet 15 and then excreted thereon, so that only the second sheet 3 is dispersed while being excreted. It is possible to receive the solid object 20 and prevent the excrement solid substance 20 from adhering to the portable toilet 15, specifically, the container 18. Thus, since the excrement solid matter 20 does not adhere to the portable toilet 15, post-processing such as cleaning of the portable toilet 15 after use can be facilitated.

  Further, the excrement adherence prevention sheet 1 is disposed in the toilet bowl of the flush toilet together with the excrement, and when the water is poured into the toilet bowl of the toilet, the first sheet 2 is dispersed by the external force due to the water flow. It can be discharged without causing troubles such as clogging of piping. As described above, the excrement adherence prevention sheet 1 can be disposed of together with the excrement in a flush toilet and can be washed away, so that the disposal of filth is easy and hygienic.

  Each of the layers 2 to 4 is made of a material that hardly pollutes the environment, and the processing can be facilitated also in this respect. For example, even if discarded in a septic tank-type toilet, no chemical is used to kill bacteria in the septic tank, and can be discarded in a septic tank-type toilet.

  Moreover, the deodorant adhesion prevention sheet 1 has a deodorant layer 4 formed thereon, and can suppress odor generated from the excrement, specifically ammonia odor. Therefore, surrounding environment deterioration can be suppressed.

  The above-described embodiment is merely an example of the present invention, and the configuration can be changed. For example, a fragrance that generates an odor that masks the ammonia odor may be attached to the excrement adhesion preventing sheet, and specifically, the fragrance layer may be formed by applying the fragrance.

  Further, the excrement adherence prevention sheet is not limited to use in the above-mentioned portable toilet, but may be used in other simple toilets such as a child's potty, or a moving body such as a train and an aircraft. You may make it use in a toilet. In any of these cases, during excretion, the dispersion of the entire excrement adherence prevention sheet is prevented, so that the solid matter of excrement is prevented from adhering to the toilet and is allowed to flow down from the toilet using a water flow. Sometimes the effect of being dispersed in the water stream and being discharged without clogging can be achieved as well.
