  The present invention relates to an absorbent device and pet sheets that can absorb liquid.

  A pet sheet used to absorb pet urine is constituted by sandwiching an absorbent sheet made of tissue and cotton-like pulp between a front sheet made of nonwoven fabric and a back sheet made of polyethylene. In this pet sheet, the front sheet is permeated and urine is absorbed by the absorbent sheet.

  As a pet sheet, there is known a pet sheet in which a reagent for urinalysis is provided in a partial region of a surface portion (see, for example, Patent Document 1).

JP-A-10-229767

  A pet sheet which is an embodiment of a conventional absorbent device has a part of components such as a tissue and a backside sheet that is opaque, or has a chromatic color even if it is transparent. With such a configuration, for the purpose of health management of pets, even if an attempt is made to confirm the color of absorbed urine, it is hidden by a non-translucent component and cannot be confirmed, or even if it can be confirmed, urine The colors of the colors are mixed with the colors of the constituent elements and appear to have different hues. Thus, the color of urine cannot be confirmed.

  In the pet sheet disclosed in Patent Document 1, urine can be inspected with a reagent. However, since urine cannot be inspected unless the pet excretes urine at a position where the reagent is present, When urine is excreted, urine cannot be examined, and the color of absorbed urine cannot be visually confirmed.

  Therefore, pet sheets that can visually confirm the color of absorbed urine so that the health condition can be confirmed are desired.

  The objective of this invention is providing the absorber and pet sheet which can confirm the color of the liquid absorbed.

The present invention includes a front surface layer having water permeability,
A backside surface layer having water impermeability;
An absorbent layer that is provided between the front surface layer and the back surface layer and absorbs liquid;

  According to the present invention, the absorption layer is provided between the front surface layer and the back surface layer, and the liquid that has passed through the front surface layer can be absorbed by the absorption layer. The front side surface layer, the back side surface layer and the absorption layer are white or colorless and transparent with translucency, so that the inside of the absorber is not concealed when visually confirming the color of the absorbed liquid, Moreover, it is prevented that the color of the component of an absorber is mixed with the color of a liquid and it looks like the color of another hue. Therefore, the color of the absorbed liquid can be visually confirmed from the outside of the absorber.

  Furthermore, when the liquid led to the absorber contains solid matter, the solid matter is captured by the surface portion of the front side surface layer and the front side surface layer side of the absorbent layer, the solid matter is separated, and the liquid is absorbed by the absorbent layer. Can be absorbed. Thereby, the color of the solid can be confirmed from the front surface layer side, and the color of the liquid can be confirmed from the back surface layer side. Therefore, the color of the liquid and the color of the solid can be confirmed without affecting each other.

Moreover, this invention is a pet sheet | seat characterized by comprising using the said absorber.
According to the present invention, it is possible to visually check the color of pet excrement and excretion fluid absorbed in pet sheets.

  ADVANTAGE OF THE INVENTION According to this invention, the highly convenient absorber which can visually confirm the color of the absorbed liquid can be obtained. And when a liquid contains a solid substance, a solid substance can be isolate | separated and the color of a liquid and the color of a fixed thing can be confirmed separately, and an extremely highly convenient absorber can be obtained.

  Moreover, according to this invention, the color of a pet excrement and excretion liquid can be confirmed, and the health state of a pet can be grasped | ascertained.

  FIG. 1 is a cross-sectional view of a pet sheet 1 according to an embodiment of the present invention. FIG. 2 is a front view of the pet sheet 1. The pet sheet 1 including an absorbent can absorb and hold excretion fluid and excretion excreted by a pet that is a liquid. In the present invention, the liquid includes not only a liquid containing no solid matter (solid) but also a liquid containing a solid matter, and the excretory fluid is a liquid not containing a solid matter, for example, urine, , A liquid containing solids, for example, soft stool.

  The pet sheet 1 that is an embodiment of the absorbent device is laminated with the absorbent sheet 4 sandwiched between the front sheet 2 and the back sheet 3, and the peripheral portions of the front sheet 2 and the back sheet 3 are fixed to each other. The absorbent sheet 4 is housed inside. The peripheral portions of the front side sheet 2 and the back side sheet 3 are fixed by adhesion using, for example, a hot-melt adhesive.

  The front side sheet 2 which is a front side surface layer is implement | achieved by the nonwoven fabric, for example, has water permeability, and can permeate | transmit a liquid. Moreover, the color of the front side sheet 2 is translucent white, that is, translucent white. Permeability means the property of allowing liquids including aqueous liquids to pass through. Translucent means a turbid color that transmits visible light (hereinafter simply referred to as “light”), but the transmitted light is irregularly reflected during transmission, and the shape becomes unclear when the opposite object is visually confirmed. . White means an almost achromatic color (including an achromatic color) with high brightness. For example, the saturation symbol in the standard color chart (conforming to JIS Z8721) defined by Japanese Industrial Standard is 0, and the pure symbol white is 10. Needless to say, it includes colors in which the saturation symbol, which is a color in the vicinity thereof, is represented by 0 or more and 1 or less and the brightness symbol is represented by 8 or more and 10 or less. As the color of the front side sheet 2, the most preferable color is pure white having a saturation symbol of 0 and a lightness symbol of 10 in the standard color chart, and a color as close to this pure white as possible is adopted.

  The back side sheet 3 which is a back side surface layer is implement | achieved by thermoplastic synthetic resins, such as polyethylene, for example, has water impermeability, and can prevent permeation | transmission of a liquid. The color of the back sheet 3 is colorless and transparent. Impermeability means the property that liquids including aqueous liquids cannot pass through. The term “transparent” refers to a clear color whose shape is clear when light is transmitted without irregular reflection and the thickness of the object is uniform when the object on the opposite side is visually confirmed. Further, colorless means a color having substantially uniform (including uniform) transmittance in all wavelength components in the visible light region. Here, the color having a substantially uniform transmittance includes a color in which the wavelength distribution of the transmitted light has the same wavelength distribution as the wavelength distribution of the reflected light from the white object described above.

  The absorbent sheet 4 that is an absorbent layer can absorb and hold the liquid that passes through the front sheet 2. The absorbent sheet 4 is configured by laminating the absorbent sheet body 5 so that the absorbent sheet body 5 is sandwiched between the absorbent sheet covering layers 6a and 6b from both sides. The entire color of the absorbent sheet 4 is white having translucency. Hereinafter, the suffixes “a” and “b” will be omitted when collectively referring to the respective absorbent sheet covering layers 6a and 6b.

  The absorbent sheet main body 5 is configured to be laminated so that a diffusion holding layer 9 made of, for example, cotton-like pulp is sandwiched between first and second coagulated layers 7 and 8 made of, for example, a water-absorbing polymer. The first and second coagulation layers 7 and 8 can absorb the liquid and coagulate and hold the absorbed liquid in a gel form. The water-absorbing polymer is, for example, sodium acrylate or potassium acrylate. The diffusion holding layer 9 can absorb the liquid, and can diffuse the absorbed liquid over a wide range by a capillary phenomenon and hold it in the space between the fibers. Cotton-like pulp is also called fluff pulp, for example.

  Each of the absorbent sheet outer layers 6 includes a front side absorbent sheet outer layer 6a that covers the absorbent sheet body 5 from the front side sheet 2 side, and a back side absorbent sheet outer layer 6b that covers the absorbent sheet body 5 from the back side sheet 3 side. Each absorbent sheet mantle layer 6 is made of a porous water-permeable sheet that allows liquid to pass through. This water-permeable sheet is realized by a thin imitation paper having water resistance called, for example, tissue. Each absorbent sheet covering layer 6 maintains a state in which constituent materials such as water-absorbing polymer and cotton-like pulp constituting the absorbent sheet main body 5 are distributed substantially uniformly without being biased, and the surface portion of the absorbent sheet 4 is made uniform. Used to do.

  More specifically, in the absorbent sheet 4, the absorbent sheet main body 5 and each absorbent sheet outer layer 6 are pressure-bonded by hot embossing. More specifically, the first and second solidified layers 7 and 8, the diffusion holding layer 9, and each absorbent sheet covering layer 6 are pressure-bonded to each other by heat embossing and integrated into a sheet having a multilayer structure. Has been. Moreover, the surface part of the absorption sheet 4 is formed in the uneven | corrugated shape by embossing.

  The pet sheet 1 has, for example, a rectangular shape projected onto a plane perpendicular to the thickness direction, the longitudinal dimension T1 is selected from 45 cm to 60 cm, and the width dimension T2 perpendicular to the longitudinal direction is from 32 cm to 44 cm. Selected below. Further, the thickness of the front side sheet 2 is 0.2 mm, the thickness of the front side absorbent sheet covering layer 6a is 0.2 mm, the thickness of the first coagulation layer 7 is 0.1 mm, the thickness of the diffusion holding layer 9 is 0.5 mm, and the second coagulation The thickness of the layer 8 is selected to be 0.1 mm, the thickness of the back side absorbent sheet mantle layer 6b is selected to be 0.2 mm, and the thickness of the back side sheet 3 is selected to be 0.3 mm. These layers are laminated to form the absorbent sheet 4.

  FIG. 3 is an enlarged cross-sectional view showing a part of the pet sheet 1. In FIG. 3, in order to facilitate understanding of the liquid absorption mechanism in the pet sheet 1, the layers are shown in a separated state. Here, a case where a pet excretes excretory fluid that does not contain solid matter will be described as an example. The pet sheet 1 is arranged so that the front side sheet 2 faces the pet when the pet performs the excretion action, and the excretion liquid excreted by the pet is used to adhere to the front side sheet 2.

  When excretion liquid that does not contain solid matter excreted by the pet adheres to the front sheet 2, the excretion liquid passes through the front sheet 2 and is guided to the absorbent sheet 4. The excretory fluid guided to the absorbent sheet 4 is first guided to the front absorbent sheet outer layer 6a.

  The front-side absorbent sheet outer layer 6a absorbs the excreted liquid that is introduced. Part of the excreted fluid that is absorbed is held in the front-side absorbent sheet outer layer 6 a, and the remainder passes through the front-side absorbent sheet outer layer 6 a and is guided to the first coagulation layer 7. The front-side absorbent sheet outer layer 6a diffuses the excreted fluid absorbed in the front-side absorbent sheet outer layer 6a in a direction crossing the thickness direction of the pet sheet 1. As a result, the excreted liquid is diffused and held in the front-side absorbent sheet outer layer 6a, and passes through the front-side absorbent sheet outer layer 6a while being diffused, and is guided to the first coagulation layer 7 in a wide range.

  The 1st coagulation layer 7 absorbs the excrement guided. Part of the absorbed excreta is solidified and held in a gel state by the first solidified layer 7, and the residue that has not been solidified passes through the first solidified layer 7 and is guided to the diffusion holding layer 9.

  The diffusion holding layer 9 absorbs the excreted liquid that is introduced. Part of the excreted fluid that is absorbed is held in the diffusion holding layer 9, and the remainder passes through the diffusion holding layer 9 and is guided to the second coagulation layer 8. The diffusion holding layer 9 diffuses the absorbed excretion fluid in the diffusion holding layer 9 in a direction crossing the thickness direction of the pet sheet 1. As a result, the excretory liquid is diffused and held in the diffusion holding layer 9, while passing through the diffusion holding layer 9 while being diffused, and further led to the second coagulation layer 8.

  The second coagulation layer 8 absorbs the excreted material that is guided. Part of the excreted matter to be absorbed is solidified and held in the form of a gel in the second coagulated layer 8, and the residue that has not been coagulated permeates the second coagulated layer 8 and leads to the back side absorbent sheet mantle layer 6b. It is burned.

  The back side absorption sheet mantle layer 6b absorbs the excreted liquid to be guided. Part of the excreted fluid to be absorbed is held in the back-side absorbent sheet outer layer 6b, and the remainder passes through the back-side absorbent sheet outer layer 6b and is guided to the back-side surface sheet 3. The back side absorbent sheet outer layer 6b diffuses the excreted fluid absorbed in the back side absorbent sheet outer layer 6b in a direction crossing the thickness direction of the pet sheet 1. As a result, the excreted liquid is diffused and held in the back-side absorbent sheet outer layer 6b, and passes through the back-side absorbent sheet outer layer 6b while being diffused, and is guided to the back-side surface sheet 3 in a wide range.

  Since the back surface sheet 3 is a water-impermeable sheet, the excreted liquid to be guided is prevented from permeating and is prevented from leaking out from the pet sheet 1 to the back side. Moreover, since the back side surface sheet 3 cannot absorb the excretion liquid, the excretion liquid is guided to the back side surface sheet 3 and is again absorbed by the back side absorption sheet mantle layer 6b.

  The excretory fluid absorbed by the back side absorbent sheet outer layer 6b is also discharged from the back side absorbent sheet outer layer 6b so as to return to the second coagulated layer 8 side, and is absorbed by the second coagulated layer 8 again, as described above. Solidified and retained. Also in the diffusion holding layer 9, the excreted liquid absorbed is also discharged from the diffusion holding layer 9 so as to return to the first coagulated layer 7 side, and is again absorbed by the first coagulating layer 7 and coagulated as described above. , Retained.

  The pet sheet 1 can absorb and retain the excretory fluid by such an absorption mechanism.

  In the pet sheet 1, the front sheet 2 and the absorbent sheet 4 have translucency, and the back sheet 3 is transparent. Therefore, from the outside of the pet sheet 1, the color of excretory fluid that passes through the front sheet 2 and is absorbed by the absorbent sheet 4 can be visually confirmed. Specifically, the color of the excretory liquid retained in the front surface sheet mantle layer 6a and the first coagulated layer 7 which is the surface portion of the absorbent sheet 4 on the front sheet 2 side is confirmed through the front sheet 2. The color of the excretory liquid retained in the back surface sheet outer layer 6b and the second coagulation layer 8 that is the surface portion of the absorbent sheet 4 on the back sheet 3 side can be confirmed through the back sheet 3. it can. Thus, the color of the excretory fluid absorbed and retained can be confirmed from both sides in the thickness direction of the pet sheet 1.

  The pet sheet 1 is configured so that the configuration on both sides is substantially symmetrical with respect to the central surface 10 in the thickness direction of the pet sheet 1, that is, the front sheet 2 and the back sheet 3 are different from each other. , Formed symmetrically. When water is attached to the top sheet 2, the ratio of the liquid absorbed in each layer of the front sheet 2 and the absorbent sheet 4 is distributed so as to be symmetric with respect to the central surface 10 of the pet sheet 1. As a result, the color of the absorbed water can be confirmed whether the front sheet 2 side or the back sheet 4 side is viewed from the outside of the pet sheet 1.

  Especially the back side sheet | seat 3 is transparent and can confirm the color of the excretion liquid absorbed with the absorption sheet 4 easily. Furthermore, since the front side sheet 2 and the absorption sheet 4 are white and the back side sheet 3 is colorless and transparent, the color of the excretory liquid is mixed with the colors of the front side sheet 2, the absorption sheet 4 and the back side sheet 3, It is prevented that the color looks different from the color of. Therefore, the color of the excretory fluid can be accurately visually confirmed without being confused by the color of the pet sheet 1.

  Furthermore, since the absorbent sheet 4 has the first and second coagulation layers 7 and 8 and coagulates and holds the excretion liquid, the pigment component of the excretion liquid can be locally aggregated. Therefore, it becomes easy to confirm the color of the excretory fluid from the outside of the pet sheet 1. Moreover, since the first and second coagulated layers 7 and 8 constitute the surface portion of the absorbent sheet main body 5, the color of the excreted liquid from the outside can be more easily confirmed.

  Since the color of the excretory fluid can be confirmed in this way, the health state of the pet can be easily grasped by easily confirming this color. Moreover, since the color can be accurately confirmed, the health condition of the pet can be accurately grasped.

  Further, when the excretory fluid is a liquid containing a liquid component having a high viscosity such as plasma contained in blood and a liquid component having a low viscosity such as urine, for example, hematuria containing plasma, the liquid component having a high viscosity is a pet sheet. 1 near the front sheet 2, specifically, the liquid component having a low viscosity absorbed and retained by the front absorbent sheet outer layer 6 a and the first solidified layer 7 is a layer near the back sheet 3 of the pet sheet 1. Specifically, it is absorbed and held by the back-side absorbent sheet outer layer 6b and the second solidified layer 8. Thus, a high-viscosity liquid such as plasma and a low-viscosity liquid such as urine can be separated and held. Therefore, the color of the liquid with high viscosity can be confirmed by viewing from the front side sheet 2 side, and the color of the liquid with low viscosity can be confirmed accurately and in detail by viewing from the back side sheet 3 side. In this way, the colors of the two components can be individually confirmed, and the health condition of the pet can be grasped more accurately and in detail.

  Furthermore, when the pet excretes excreta containing solid matter, such as loose stool, the liquid component excluding the solid matter is absorbed by the pet sheet 1 by the same mechanism as described above. At this time, the solid matter is captured on the surface portion of the top sheet 2, the front absorbent sheet outer layer 6 a, and the first solidified layer 7 on the front sheet 2 side. In this way, the solid is separated from the liquid component and captured.

  In this way, when soft stool is absorbed and held, the color of the solid can be confirmed by viewing from the front sheet 2 side, and the color of the liquid component can be confirmed by viewing from the back sheet 3 side. . In this way, solids and liquid components can be separated and the colors can be individually confirmed. Thus, even in the case of excrement that is loose stool, the color can be confirmed more accurately and in detail, and the health condition of the pet can be grasped more accurately and in detail.

  FIG. 4 is an enlarged cross-sectional view showing a state where the pet sheet 1 has absorbed hematuria including blood cells. Further, when the excreta containing solid matter is urine containing blood cells such as red blood cells which are solid matter, that is, hematuria, the blood cells which are solid matter are the same as the loose stool. And it is captured by the surface portion of the first solidified layer 7 on the front sheet 2 side.

  More specifically, as described above, solid matter such as blood cells is captured on the front sheet 2 side with respect to the center surface 10, and the amount captured in the vicinity of the first coagulation layer 7 is the largest, and as it goes to both sides in the thickness direction. Captured and retained with a blood distribution that reduces the amount of capture. In this way, blood cells are separated from urine and captured.

  Therefore, when absorbing and holding hematuria, the color of the blood cell can be confirmed by viewing from the front sheet 2 side, and the color of urine can be confirmed by viewing from the back sheet 3 side. In this way, blood cells and urine can be separated and colors can be individually confirmed. Thus, even in the case of excrement that is hematuria, the color can be confirmed more accurately and in detail, and the health condition of the pet can be grasped more accurately and in detail.

  As described above, as described with some examples of the excretory fluid and excrement, by absorbing and holding the excretory fluid and excrement in the pet sheet 1, the color can be easily and accurately adjusted. It can be confirmed in detail. For example, when hematuria is absorbed and held as described above, the color of excreted blood such as red blood cells and plasma can be confirmed by visual observation from the front sheet 2 side, and that red blood cells and plasma are contained in the hematuria. I can confirm. This makes it possible to grasp that the pet may develop urinary tract diseases such as urinary calculi.

  Moreover, when the back sheet 3 side is visually observed, the color of urine can be confirmed. For example, when hemoglobin is contained in urine, the hemoglobin dissolves in urine. Therefore, when viewed from the back sheet 3 side, the second water-absorbing polymer 8 and the absorbent sheet outer layer 6b that absorb urine appear reddish brown. As a result, it can be confirmed that hemoglobin is dissolved in urine, and it is possible to grasp that there is a fear of developing kidney diseases such as kidney stones and pyelonephritis.

  In addition, when the pet excretes urine containing glycoprotein which is a solid substance, the glycoprotein is captured by the layers on the front sheet 2 side such as the front sheet 2, the front absorbent sheet mantle layer 6a and the first coagulation layer 7. When viewed from the front sheet 2 side, a white solid is visible. In this case, glycoprotein may be contained in urine, and it can be grasped that there is a fear of developing diabetes.

  In this way, the color of excretory fluid and excrement absorbed and retained by the pet sheet 1 can be visually confirmed on both the front sheet 2 side and the back sheet side 3 side of the pet sheet 1. As a result, the health condition of the pet can be easily and accurately grasped in detail.

  In the present embodiment, the pet sheet 1 includes the front side sheet 2, the back side sheet 3, and the absorbent sheet 4, but in addition to this, a test agent may be included in the pet sheet 1. For example, when measuring the pH (ph) of urine, if the ph test paper is placed inside the diffusion holding layer, the urine from which the solid matter has been removed adheres to the ph test paper, and the urine pH does not contain the solid matter. Measurement is possible. Therefore, the correct ph value of urine can be obtained by viewing the test paper from the back sheet 3 side. In this way, the excrement can be separated into solid and liquid, and the solid and liquid can be inspected and measured with separate test drugs, and the health condition of the pet can be grasped.

  In the present embodiment, the case of using for pets has been described. However, the excrement excreted by humans can be attached so that the solid and liquid color of excrement can be confirmed from the outside, and the health condition is confirmed. You may be able to do that.
