Description

Technical Field

[0001] This invention relates to permeable mats, pet toilet systems, and packaging. Background Technology

[0002] Pet toilet systems for treating the excrement of pets such as dogs and cats are known. For example, Patent Document 1 describes a pet toilet system comprising a tray, an absorbent sheet disposed on the tray, and a corrugated cardboard board with a corrugated honeycomb structure disposed on the absorbent sheet. In this pet toilet system, when a pet urinates on the board, the urine is absorbed by the absorbent sheet through the board. By disposing of the board on the absorbent sheet, the pet does not come into direct contact with the absorbent sheet, thereby preventing the urine absorbed by the absorbent sheet from flowing back towards the pet's legs.

[0005] Patent Document 1: Japanese Patent Application Publication No. 2012-205541 Summary of the Invention

[0006] The problem the invention aims to solve

[0007] Many pet owners want their pets to use indoor toilets to keep their homes clean, but it's not easy to get pets used to it. Generally, pets prefer to relieve themselves in a clean and comfortable environment, and even if a toilet isn't provided to their liking, they will mostly resist using it. For example, the panel described in Patent Document 1 is made of corrugated cardboard, which has a hard and textured surface, making it unpalatable to pets, sometimes causing them to avoid using the toilet. Without providing a comfortable environment for pets to eliminate waste, it's difficult to promote the use of pet toilet systems.

[0008] Therefore, the purpose of this disclosure is to provide a permeable mat that provides a comfortable excretion environment for pets, a pet toilet system containing the permeable mat, and a package for storing the permeable mat.

[0009] Solution for solving the problem

[0010] One proposed solution involves using a permeable pet mat over an absorbent sheet. This permeable mat has a porous structure and, in a dry state, exhibits a compressive energy (WC value) of 13 gf·cm / cm², as determined by a KES compression test. 2 Above and 60 gf·cm / cm 2 the following.

[0011] The compression work obtained through the KES compression test is the work done when a permeable pad is compressed along its thickness to the maximum pressure. A higher value indicates that the permeable pad is softer and more easily compressed. In a dry state, the compression work of the permeable pad is set to 13 gf·cm / cm. 2 This provides the pet with the cushioning they desire. On the other hand, if the permeable mat is too soft, it will be over-compressed when the pet steps on it, causing the pet's legs to come into contact with the absorbent pad, and potentially allowing urine absorbed by the pad to flow back up the pet's legs. In contrast, setting the compression work of the permeable mat to 60 gf·cm / cm... 2 This prevents soiling of the pet's legs. Therefore, using this permeable mat provides a clean and comfortable environment for the pet to eliminate waste.

[0012] The compressive energy (WC value) of a permeable mat under wet conditions, obtained through a KES compression test, can also be 13 gf·cm / cm. 2 Above and 60 gf·cm / cm 2 The following applies. In this case, even in a moist environment, a clean and comfortable elimination environment can be provided for the pet.

[0013] Permeable mats can also be made of polyurethane resin. By using polyurethane resin to make permeable mats, pets can be given a cushioning effect they like, providing a comfortable environment for them to eliminate waste.

[0014] When viewed from the thickness direction, the permeable mat Brightness in the color system It can also be below 55. Since pets such as dogs tend to avoid urinating on absorbent pads, they sometimes object to urinating on used pads even when they can absorb urine. By making the absorbent pads dark, the visual visibility of urine stains on the absorbent pads decreases, allowing for reuse.

[0015] Permeable pads can also have a thickness of 2mm or more but less than 7mm in their natural state. By setting the thickness of the permeable pad to 2mm or more, the compression of the permeable pad when the pet steps on it helps prevent urine from flowing back to the pet's legs due to contact with the absorbent pad. By setting the thickness of the permeable pad to less than 7mm, it is possible to impart permeability to the permeable pad.

[0016] The permeable pad is applied at a thickness of 990 g / cm. 2 The thickness under load can also be 0.5 mm or more. In this case, it can prevent urine from flowing back to the pet's legs due to contact between the pet's legs and the absorbent pad.

[0017] When viewed from the thickness direction of the permeable pad, the number of pores per square inch can be more than 8 and less than 20. By setting the number of pores per square inch of the permeable pad to more than 8 and less than 20, urine excreted onto the permeable pad can permeate and be absorbed by the absorbent sheet.

[0018] The tensile strength of the permeable pad in the wet state can also be 8 N / mm. 2 That's all. In this case, even if the pet urinates repeatedly on the permeable mat, the permeable mat is not easily damaged, so it can be used for a long time without needing to be replaced.

[0019] The tensile strength of a permeable mat in its dry state can be more than 90% and less than 110% of its tensile strength in its wet state. In this case, the permeable mat is not easily damaged when a pet urinates on it and the mat becomes wet, thus allowing for repeated use over a long period of time.

[0020] Hydrophilic agents can also be applied to permeable pads. Applying hydrophilic agents to permeable pads inhibits urine residue from remaining on their surface. As a result, the permeable pads can be kept clean.

[0021] Permeable pads can also contain antibacterial agents containing silver ions. In this case, the permeable pad can be kept clean by using antibacterial agents containing silver ions to suppress the odor of urine.

[0022] Permeable mats can also have a strength of 25 kg / m³. 3 Above and 35kg / m 3 The following apparent densities are used. By setting the apparent density of the permeable pad within the above range, it is possible to impart appropriate permeability to the permeable pad.

[0023] Permeable mats can also have an air permeability of 0.001 or higher and 0.006 or lower. By setting the air permeability of the permeable mat within the above range, it is possible to impart appropriate permeability to the permeable mat.

[0024] One proposed pet toilet system comprises: an absorbent sheet, which is absorbent; a permeable mat, which is placed on the absorbent sheet; and a toilet body that holds the absorbent sheet and the permeable mat. The permeable mat has a porous structure and, in a dry state, exhibits a compression work (WC value) of 13 gf·cm / cm², as determined by a KES compression test. 2 Above and 60 gf·cm / cm 2 the following.

[0025] In a dry state, the compressive work (WC value) of the permeable pad is set to 13 gf·cm / cm. 2 Above and 60 gf·cm / cm 2This provides a clean and comfortable elimination environment for pets, thereby promoting the use of pet toilet systems.

[0026] One solution involves packaging a pet-safe, permeable mat that is placed on an absorbent sheet. The permeable mat has a porous structure and, in a dry state, exhibits a compression work (WC value) of 13 gf·cm / cm², as determined by a KES compression test. 2 Above and 60 gf·cm / cm 2 The inner surface of the packaging is made of resin film.

[0027] Because the inner surface of the packaging is made of a resin film, the friction between the inner surface of the packaging and the permeable pad is reduced, making it easy to remove the permeable pad from the packaging.

[0044] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same elements are labeled with the same reference numerals, and repeated descriptions are omitted. For ease of understanding, some parts may be simplified or exaggerated in the drawings, and the dimensions are not limited to those shown in the drawings.

[0045] The following describes a pet system toilet (hereinafter referred to as "system toilet") including a permeable pad for pets according to one embodiment. Figure 1 This is a perspective view of a system toilet 1 according to one embodiment. Figure 2 It is a three-dimensional view showing the main components of the toilet system 1 in a decomposed manner. Figure 3 It is along Figure 1 A cross-sectional view along line AA. Figure 4 It is an enlarged representation Figure 3 A cross-sectional view of the fitting part of the toilet system 1 shown.

[0046] Figures 1-4 The toilet system 1 shown is a pet excretion device. In this specification, "pet" broadly includes vertebrates and invertebrates, typically including pets such as dogs, cats, rabbits, and hamsters. Typically, the toilet system 1 is installed indoors for pets kept indoors, providing an excretion space. Pet excrement is typically urine, but also includes low-viscosity feces, saliva, blood, and other bodily fluids.

[0047] like Figure 1 As shown, the system toilet 1 includes a toilet body 2, an absorbent sheet 3 with water-absorbing properties, and a permeable mat 4 disposed on the absorbent sheet 3. The toilet body 2 holds the absorbent sheet 3 and the permeable mat 4.

[0048] Furthermore, in the following description, the stacking direction of the absorbent sheet 3 and the permeable pad 4 will be referred to as the "vertical direction Z," and the two directions perpendicular to the vertical direction Z will be referred to as the "width direction X" and the "depth direction Y," respectively. Figure 1In the embodiment shown, the width direction X is parallel to the long side of the toilet body 2, and the depth direction Y is parallel to the short side of the toilet body 2. Furthermore, the direction from the absorbent sheet 3 toward the permeable pad 4 is referred to as "upper," and the direction from the permeable pad 4 toward the absorbent sheet 3 is referred to as "lower."

[0049] The toilet body 2 is a device for holding the absorbent sheet 3 and the permeable mat 4. For example... Figure 2 As shown, the toilet body 2 includes a base plate 11, a middle frame 12 disposed on the base plate 11, and an upper frame 13 disposed on the middle frame 12. The base plate 11, the middle frame 12, and the upper frame 13 are formed, for example, by molding thermoplastic resin and are flexible. As described later, the base plate 11, the middle frame 12, and the upper frame 13 can be disassembled and reassembled with each other in the vertical direction Z.

[0050] Figure 5 This is a three-dimensional view of the base plate 11 of the main toilet body 2. (See diagram below.) Figure 5 As shown, when viewed from the vertical direction Z, the base plate portion 11 has a generally rectangular bottom portion 21 with the width direction X as its long side and an outer edge portion 22 surrounding the bottom portion 21. The bottom portion 21 has an upper surface 23 for mounting the absorbent sheet 3. The upper surface 23 of the bottom portion 21 has a concave-convex shape. Specifically, the upper surface 23 has a plurality of recesses 23a that are recessed downwards and convex portions 23b that are raised upwards. The plurality of recesses 23a are arranged in a two-dimensional manner along the width direction X and the depth direction Y. When viewed from the vertical direction Z, the plurality of recesses 23a are each formed into a quadrilateral shape (square shape). The convex portions 23b are formed into a grid shape that divides the plurality of recesses 23a.

[0051] When viewed from above in the Z-direction, the outer edge 22 is formed in a generally rectangular frame shape, arranged to surround the bottom surface 21. Typically, the outer edge 22 is integrally formed with the bottom surface 21 using thermoplastic resin. The outer edge 22 has: a sidewall portion 24 that rises upward from the outer edge of the bottom surface 21; an inner peripheral portion 25 that extends outward from the upper end of the sidewall portion 24; and an outer peripheral portion 26 that extends outward from the outer edge of the inner peripheral portion 25. The sidewall portion 24 functions to block urine that is excreted onto the bottom surface 21 via the permeable pad 4 and the absorbent sheet 3. A notch (not shown) may also be formed in the sidewall portion 24 to allow urine that has entered the fitting recess 27 (described later) to return to the bottom surface.

[0052] The inner peripheral portion 25 is located on the outer side of the side wall portion 24, and has an upper surface 25a positioned above the upper surface 23 of the bottom portion 21 (see reference). Figure 4A fitting recess (first fitting recess) 27 is formed in the inner peripheral portion 25, recessed downward from the upper surface 25a of the inner peripheral portion 25. When viewed from the vertical direction Z, the fitting recess 27 is a generally rectangular groove formed in the area between the side wall portion 24 and the outer peripheral portion 26. The bottom of the fitting recess 27 is positioned above the upper surface 23 of the bottom portion 21 and below the upper surface 25a of the inner peripheral portion 25.

[0053] The outer peripheral portion 26 is located outside the inner peripheral portion 25 and has an upper surface 26a positioned above the upper surface 25a of the inner peripheral portion 25. A pair of ends of the outer peripheral portion 26 in the depth direction Y have cutout portions 26b formed by cutting a portion of the outer peripheral portion 26 towards the depth direction Y. A columnar connecting portion 28 is provided in the cutout portion 26b. The connecting portion 28 extends along the width direction X and its two ends are connected to the outer peripheral portion 26.

[0054] Figure 6 This is a 3D view of the middle frame section 12. Figure 7 This is a bottom view of the middle frame portion 12. When viewed from the top and bottom (Z), the middle frame portion 12 has a generally rectangular frame shape and is detachably mounted on the outer edge 22 of the base plate portion 11. The middle frame portion 12 includes an inner peripheral portion 31 and an outer peripheral portion 32 disposed outside the inner peripheral portion 31. When the middle frame portion 12 is mounted on the base plate portion 11, the inner peripheral portion 31 of the middle frame portion 12 is positioned above the inner peripheral portion 25 of the base plate portion 11, and the outer peripheral portion 32 of the middle frame portion 12 is positioned above the outer peripheral portion 26 of the base plate portion 11.

[0055] like Figure 4 and Figure 6 As shown, the inner peripheral portion 31 has a fitting protrusion (first fitting protrusion) 33 and a fitting recess (second fitting recess) 34. The fitting protrusion 33 is formed along the inner edge of the middle frame portion 12 and has a generally rectangular shape when viewed from below. The fitting protrusion 33 protrudes downward from the lower surface of the middle frame portion 12 (towards the base plate portion 11). The fitting protrusion 33 is positioned opposite to the fitting recess 27 of the bottom portion 21 and can engage with the fitting recess 27. When the fitting protrusion 33 engages with the fitting recess 27, the base plate portion 11 and the middle frame portion 12 are connected, and the horizontal displacement (width direction X and depth direction Y) of the base plate portion 11 and the middle frame portion 12 can be suppressed. The fitting recess 27 and the fitting protrusion 33 constitute a lower fitting structure 10 connecting the base plate portion 11 and the middle frame portion 12.

[0056] The fitting recess 34 is recessed downward from the upper surface of the inner peripheral portion 31. The fitting recess 34 is a generally rectangular groove, positioned outside the fitting protrusion 33 when viewed from the vertical direction Z. Alternatively, when viewed from the vertical direction Z, the depth of the fitting recess 34 (the vertical distance Z from the upper surface of the inner peripheral portion 31 to the bottom of the fitting recess 34) may be greater than the depth of the fitting recess 27 (the vertical distance Z from the upper surface 25a of the inner peripheral portion 25 to the bottom of the fitting recess 27).

[0057] One or more openings 37 may also be formed at the bottom of the fitting recess 34 (see reference). Figure 7 Multiple openings 37 are through holes that penetrate the middle frame portion 12 along the thickness direction (vertical direction Z), allowing urine entering the fitting recess 34 to be discharged towards the bottom portion 21.

[0058] The outer periphery 32 of the middle frame portion 12 has an outer peripheral protrusion 35. The outer peripheral protrusion 35 is formed along the outer edge of the middle frame portion 12. When viewed from below, the outer peripheral protrusion 35 has a generally rectangular shape and protrudes downward from the outer edge of the middle frame portion 12 (towards the base plate portion 11). Figure 4 As shown, the top end of the outer peripheral protrusion 35 is positioned above the top end of the fitting protrusion 33 and below the bottom of the fitting recess 34. When the fitting protrusion 33 of the middle frame portion 12 is fitted with the fitting recess 27 of the base plate portion 11, the outer peripheral protrusion 35 is supported on the outer peripheral portion 26 of the base plate portion 11.

[0059] The middle frame portion 12 has a pair of first middle frame edges 12A extending along the width direction X and a pair of second middle frame edges 12B extending along the depth direction Y. For example... Figure 6 As shown, the length of the first middle frame edge 12A in the width direction X is longer than the length of the second middle frame edge 12B in the depth direction Y. Alternatively, the width w2 of the second middle frame edge 12B in the width direction X is smaller than the width w1 of the first middle frame edge 12A in the depth direction Y.

[0060] A pair of first middle frame edges 12A have latches (second locking structures) 38 for locking the middle frame portion 12 to the base plate portion 11. The latches 38 include: a latch body 38a extending downward from the outer edge of the pair of first middle frame edges 12A; and a protrusion 38b disposed inside the latch body 38a in the depth direction Y, facing the latch body 38a across a gap 38s (see reference). Figure 7 ).

[0061] The latch body 38a has a first claw portion 38c and a second claw portion 38d. The first claw portion 38c protrudes inward from the inner surface of the latch body 38a in the depth direction Y. The second claw portion 38d protrudes outward from the outer surface of the latch body 38a in the depth direction Y. When the middle frame portion 12 is mounted on the base plate portion 11, the connecting portion 28 of the base plate portion 11 is received in the gap 38s, and the first claw portion 38c is locked to the connecting portion 28 by the elastic deformation of the latch body 38a. Thus, the middle frame portion 12 is fixed to the base plate portion 11.

[0062] Figure 8 This is a 3D view of the upper frame 13. Figure 9 This is a bottom view of the upper frame portion 13. When viewed from the vertical direction Z, the upper frame portion 13 has a generally rectangular frame shape and is detachably mounted on the middle frame portion 12. The upper frame portion 13 has an inner peripheral portion 41 and an outer peripheral portion 42 disposed outside the inner peripheral portion 41. When the upper frame portion 13 is mounted on the middle frame portion 12, the inner peripheral portion 41 of the upper frame portion 13 is positioned above the inner peripheral portion 31 of the middle frame portion 12, and the outer peripheral portion 42 of the upper frame portion 13 is positioned above the outer peripheral portion 32 of the middle frame portion 12.

[0063] The inner peripheral portion 41 of the upper frame portion 13 has an inner peripheral convex portion 43 and a fitting convex portion (second fitting convex portion) 44 (see Figure 4 The inner peripheral protrusion 43 is formed along the inner edge of the upper frame portion 13 and is generally rectangular in shape when viewed from below. The inner peripheral protrusion 43 protrudes downward from the inner edge of the upper frame portion 13 toward the bottom plate portion 11.

[0064] Viewed from below, the fitting protrusion 44 has a generally rectangular shape and is positioned outside the inner peripheral protrusion 43. The fitting protrusion 44 is positioned opposite the fitting recess 34 of the middle frame portion 12, protruding downwards from the lower surface of the upper frame portion 13 toward the fitting recess 34. The fitting protrusion 44 can engage with the fitting recess 34. When the fitting protrusion 44 engages with the fitting recess 34, the middle frame portion 12 and the upper frame portion 13 are connected, suppressing any horizontal displacement (width direction X and depth direction Y) between the middle frame portion 12 and the upper frame portion 13. The fitting recess 34 and the fitting protrusion 44 constitute an upper fitting structure 20 connecting the middle frame portion 12 and the upper frame portion 13.

[0065] like Figure 4 As shown, when the fitting recess 34 and the fitting protrusion 44 are engaged, the lower end of the inner peripheral protrusion 43 is positioned below the lower end of the fitting protrusion 44. Alternatively, the maximum length of the fitting protrusion 44 of the upper frame portion 13 may be longer than the maximum length of the fitting protrusion 33.

[0066] The outer periphery 42 of the upper frame portion 13 has an outer peripheral protrusion 45. The outer peripheral protrusion 45 is formed along the outer edge of the upper frame portion 13. When viewed from below, the outer peripheral protrusion 45 has a generally rectangular shape and protrudes downwards from the outer edge of the upper frame portion 13 toward the middle frame portion 12. Figure 4 As shown, when the upper frame portion 13 is mounted on the middle frame portion 12 and the fitting protrusion 44 and the fitting recess 34 are engaged, the outer peripheral protrusion 45 of the upper frame portion 13 is supported on the outer peripheral protrusion 35 of the middle frame portion 12.

[0067] like Figure 8 As shown, the upper frame portion 13 has a pair of first upper frame edges 13A extending along the width direction X and a pair of second upper frame edges 13B extending along the depth direction Y. The length of the pair of first upper frame edges 13A in the width direction X is longer than the length of the pair of second upper frame edges 13B in the depth direction Y. Alternatively, the width w4 of the pair of second upper frame edges 13B in the width direction X may be smaller than the width w3 of the pair of first upper frame edges 13A in the depth direction Y.

[0068] A pair of first upper frame edges 13A have latches (first locking structures) 46 for locking the upper frame portion 13 to the middle frame portion 12. The latches 46 extend downward from the outer edge of the first upper frame edges 13A. An opening 46a is formed in the latches 46 that extends through the latches 46 in the thickness direction (depth direction Y). When the upper frame portion 13 is installed on the middle frame portion 12, the latches 46 elastically deform in a way that expands outward in the depth direction Y while sliding along the outer surface of the latches 38, and the second claw portion 38d of the latches 38 engages with the opening 46a of the latches 46. Thus, the upper frame portion 13 is fixed to the middle frame portion 12. Figure 10 This is a side view of the toilet body 2, which is formed by the engagement of the latch 46 of the upper frame 13 and the latch 38 of the middle frame 12, connecting the bottom plate 11, the middle frame 12 and the upper frame 13.

[0069] like Figure 8 As shown, the upper frame portion 13 has an upper surface 47 that slopes downwards (near the bottom plate portion 11) from the outer edge of the upper frame portion 13 toward the inner edge. The upper surface 47 is a curved surface whose slope angle increases as it approaches the inner edge of the upper frame portion 13. By sloped as described above, when a pet's urine falls onto the upper frame portion 13, the urine can fall along the upper surface 47 toward the bottom surface 21.

[0070] In one embodiment, the upper surface 47 of the upper frame portion 13 may also have an uneven shape. For example, on a pair of first upper frame edges 13A of the upper frame portion 13, a plurality of raised portions (protrusions) 48 extending in the depth direction Y are arranged at equal intervals along the width direction X. Similarly, on a pair of second upper frame edges 13B of the upper frame portion 13, a plurality of raised portions 48 are arranged at equal intervals along the depth direction Y. An inclined surface (recess) 49 is formed between the plurality of raised portions 48 to allow urine to flow toward the absorbent sheet 3. That is, the upper surface 47 of the pair of first upper frame edges 13A has raised portions 48 and inclined surfaces 49 alternately arranged in the width direction X, and the upper surface 47 of the pair of second upper frame edges 13B has raised portions 48 and inclined surfaces 49 alternately arranged in the depth direction Y. The inclined surface 49 is curved downwards as it moves away from the adjacent raised portion 48. That is, since the center of the inclined surface 49 is the lowest in the width direction X or depth direction Y, the urine on the upper frame 13 collects at the center of the inclined surface 49 and is guided to the lower surface 21.

[0071] The toilet body 2 holds an absorbent sheet 3 and a permeable mat 4. The absorbent sheet 3 is a thin sheet material with absorbent properties, disposed on the bottom surface 21 of the base plate 11, to absorb pet urine. The absorbent sheet 3 has a generally rectangular planar shape and dimensions corresponding to the size of the toilet body 2. For example, the absorbent sheet 3 has a length of 400mm to 600mm in the long side direction and a width of 300mm to 500mm in the short side direction. The absorbent sheet 3 is disposed and held between the base plate 11 and the middle frame 12 of the toilet body 2.

[0072] Figure 11 This is a schematic top view of absorbent sheet 3. Figure 12 It is along Figure 11 A cross-sectional view along the BB line. For example... Figure 11 and Figure 12 As shown, the absorbent sheet 3 comprises: a front sheet 51 disposed on the front side of the absorbent sheet 3; a back sheet 52 disposed on the back side of the absorbent sheet 3; and an absorbent body 53 disposed between the front sheet 51 and the back sheet 52. The front sheet 51 is liquid-permeable and is formed into a generally rectangular shape. The front sheet 51 is made of a resin film having a plurality of openings 51a extending through the front sheet 51 in the thickness direction. Typically, polyethylene or polypropylene is used as the material of the resin film. In addition, the front sheet 51 may also be made of a laminate formed by bonding nonwoven fabric to the resin film, or a waterproof nonwoven fabric. Pet urine excreted into the absorbent sheet 3 moves toward the absorbent body 53 through the openings 51a formed in the front sheet 51.

[0073] The back sheet 52 is waterproof and is formed into a generally rectangular shape with substantially the same dimensions as the front sheet 51. Examples of materials for the back sheet 52 include a resin film such as polyethylene or polypropylene, a laminate formed by bonding a nonwoven fabric to the resin film, or a waterproof nonwoven fabric. By placing the liquid-impermeable back sheet 52 on the back side of the absorbent sheet 3, leakage of urine excreted onto the absorbent sheet 3 to the back side is prevented.

[0074] Absorbent 53 is disposed between the front sheet 51 and the back sheet 52, absorbing urine that has passed through the front sheet 51. Absorbent 53 has a generally rectangular planar shape and is smaller than both the front sheet 51 and the back sheet 52, and is disposed in the center of the absorbent sheet 3. Therefore, as... Figure 11 As shown, the absorbent sheet 3 has an absorbent portion 3a with an absorber 53 disposed between the front sheet 51 and the back sheet 52, and a wing portion 3b without an absorber 53 disposed between the front sheet 51 and the back sheet 52. Viewed in the thickness direction, the absorbent portion 3a is a generally rectangular area disposed in the center of the absorber 53, partially bonded to the front sheet 51 using a hot melt adhesive HM. The wing portion 3b is a rectangular frame-shaped area that adheres to the front sheet 51 and the back sheet 52 without any absorber in between, formed to surround the absorbent portion 3a. That is, the wing portion 3b is formed along the outer edge of the absorbent sheet 3. Typically, as... Figure 12 As shown, in the wing 3b, the front sheet 51 and the back sheet 52 are directly bonded together using hot melt adhesive HM without being separated by the absorber 53.

[0075] The absorbent 53 includes an absorbent core 54 containing pulp and a superabsorbent polymer (SAP), and a core-cladding layer 55 covering the surface of the absorbent core. The pulp of the absorbent core 54 may be, for example, chemical pulp, cellulose fibers, rayon, cellulose acetate, or other cellulose fibers. The SAP may be, for example, a starch-based, acrylic-based, or amino acid-based granular or fibrous polymer. The core-cladding layer 55 is wound around the absorbent core 54 in a manner that covers at least a portion of the surface of the absorbent core 54.

[0076] The absorbent sheet 3 may also include a cover sheet 56. The cover sheet 56 is disposed between the front sheet 51 and the absorbent core 54, covering the front side of the absorbent core 54. The cover sheet 56 has a generally rectangular planar shape and has substantially the same dimensions as the absorbent body 53 when viewed in the thickness direction. The cover sheet 56 is made of, for example, cotton paper or nonwoven fabric and is liquid-permeable.

[0077] The absorbent sheet 3 is disposed between the base plate 11 and the middle frame 12 of the toilet body 2. When the base plate 11 and the middle frame 12 are connected by the absorbent sheet 3, as... Figure 4As shown, the wing 3b of the absorbent sheet 3 is clamped between the fitting recess 27 and the fitting protrusion 33, and is held between the base plate portion 11 and the middle frame portion 12. By clamping the wing 3b of the absorbent sheet 3, damage to the absorbent body 53 and leakage of SAP from the absorbent sheet 3 are prevented.

[0078] The permeable mat 4 is a thin sheet material with a porous structure and water permeability. The permeable mat 4 is held between the middle frame 12 and the upper frame 13 of the toilet body 2 and is used on the absorbent sheet 3. The permeable mat 4 allows pet urine to pass through while preventing urine from flowing back from the absorbent sheet 3. The permeable mat 4 is made of a foaming resin, such as polyurethane resin, with a continuous bubble structure (open-cell structure). Because polyurethane resin has high water resistance, the permeable mat 4 can be repeatedly used without replacement by being made of polyurethane resin. For example, an ether-based polyurethane resin with high tensile strength is used as the polyurethane resin.

[0079] Figure 13 This is a top view showing an enlarged portion of a permeable pad 4 according to one embodiment. (See attached image.) Figure 13 As shown, a plurality of pores 4a are formed in the permeable pad 4, extending through the pad 4 along its thickness direction. Alternatively, when viewed from the thickness direction, there may be 8 to 20 pores 4a per square inch in the permeable pad 4. By setting the number of pores 4a per square inch to 8 to 20, it is possible to ensure liquid permeability while maintaining the rigidity of the permeable pad 4. Furthermore, the opening shape of the pores 4a can be any planar shape, such as circular, elliptical, or polygonal.

[0080] like Figure 2 As shown, the permeable mat 4 is used on the absorbent sheet 3. Furthermore, the permeable mat 4 can also be disposed separately from the absorbent sheet 3 without applying a load. A pet using the system toilet 1 climbs onto the permeable mat 4 to urinate. The pet's urine moves towards the absorbent sheet 3 through the holes 4a formed in the permeable mat 4 and is absorbed by the absorbent body 53 of the absorbent sheet 3. At this time, since the permeable mat 4 prevents the pet's legs from contacting the absorbent sheet 3, the urine absorbed by the absorbent sheet 3 can be prevented from flowing back towards the pet's legs.

[0081] Generally, pets such as dogs prefer to defecate in an environment with moderate cushioning. Therefore, if the stiffness of the permeable mat 4 is too high, it will not meet the pet's preference, and they may sometimes avoid using the toilet. Therefore, the compressive energy (WC value) of the permeable mat 4, obtained through a KES compression test in a dry state, was set to 13 gf·cm / cm². 2 Above and 60 gf·cm / cm 2The compression work obtained through the KES compression test is the work done when the permeable pad 4 is compressed in the thickness direction up to the maximum pressure. The higher the value, the softer and more easily the permeable pad 4 is compressed.

[0082] Compression work can be measured using, for example, the Kato KES-G5 handheld compression tester. When measuring compression work, for example, a 5cm × 10cm permeable pad test piece is mounted on the test bench, and the test piece is subjected to compression testing on a surface with an area of ​​2cm². 2 The steel plates, arranged in a circular plane, were compressed from the thickness direction. The compression rate was set to 20 μm / sec, and the maximum compression load was set to 4.9 kPa. Then, the load P on the test piece was measured at 4.9 kPa (50 gf / cm²). 2 The thickness Tm of the test piece under load and 49 Pa (0.5 gf / cm²) 2 The thickness T0 under load is used to calculate the compressive work WC of the permeable pad 4 based on the following formula (1).

[0083] [Number 1]

[0084]

[0085] In the dry state, the compression work of the permeable pad 4 is set to 13 gf·cm / cm. 2 This provides the pet with the cushioning they desire. On the other hand, if the permeable pad is too soft, it will be excessively compressed when the pet steps on it, causing the pet's legs to come into contact with the absorbent pad 3, and potentially causing urine absorbed by the absorbent pad 3 to flow back towards the pet's legs. In contrast, by setting the compression work of the permeable pad 4 to 60 gf·cm / cm... 2 This will prevent contamination of your pet's legs.

[0086] Even when wet, the permeable pad 4 exhibits a compression work of 13 gf·cm / cm², as determined by the KES compression test. 2 Above and 60 gf·cm / cm 2 The following refers to the state where the water-permeable pad 4 is soaked in water for 5 minutes and then the water on the surface of the water-permeable pad 4 is wiped off with a cloth.

[0087] In addition, the tensile strength of the permeable pad 4 in a wet state can also be 8 N / mm. 2The above. For example, a 25mm × 150mm test piece can be cut from the permeable pad 4, and the two ends of the test piece are stretched at a speed of 100mm / min using an Autograph testing apparatus. The force [N] required to tear the test piece is taken as the tensile strength of the permeable pad 4. The tensile strength of the permeable pad 4 in the dry state can also be more than 90% and less than 110% of the tensile strength in the wet state. By setting the tensile strength of the permeable pad 4 to 8 N / mm 2 The above measures can prevent the permeable mat 4 from breaking when the pet moves on it.

[0088] The permeable mat 4 has a generally rectangular planar shape and dimensions corresponding to the size of the toilet body 2. For example, the permeable mat 4 has a length of 400mm to 600mm in the long side direction and a width of 300mm to 500mm in the short side direction.

[0089] Furthermore, the thickness of the permeable pad 4 is 2mm or more and less than 7mm in its natural state. By setting the thickness of the permeable pad 4 to 2mm or more, the compression of the permeable pad 4 when the pet steps on it helps to prevent urine from flowing back to the pet's legs due to contact with the absorbent sheet 3. By setting the thickness of the permeable pad 4 to less than 7mm, the permeability of the permeable pad 4 can be ensured. In addition, to prevent urine from flowing back to the pet's legs, the permeable pad 4 can also have a thickness of 990g / cm². 2 The thickness and stiffness become 0.5 mm or more when under load.

[0090] In addition, the permeable pad 4 can also have a strength of 25 kg / m³. 3 Above and 35kg / m 3 The following is the apparent density. Apparent density refers to the mass per unit volume, including the volume of the numerous pores 4a. The higher the proportion of the pore volume 4a in the volume of the permeable pad 4, the lower the apparent density. The apparent density of the permeable pad 4 is set to 25 kg / m³. 3 The above measures improve the stiffness of the permeable pad 4, preventing it from being compressed and the pet's legs from contacting the absorbent sheet 3. Furthermore, by setting the apparent density of the permeable pad 4 to 25 kg / m³... 3 The above ensures the permeability of the permeable pad 4.

[0091] The permeable pad 4 can also have an air permeability of 0.001 or higher and 0.006 or lower. The air permeability can be calculated, for example, by the following formula.

[0092] Breathability (CC / cm) 2 / sec)=12.5 / air permeability resistance value

[0093] For the air permeability resistance value, for example, a test piece of a predetermined size is cut from the permeable pad 4, and the air permeability resistance value of the test piece is measured using an air permeability testing machine (KES-F8) manufactured by Kato Technology Co., Ltd., or an equivalent air permeability testing machine. For example, air is released and drawn through the test piece at a constant flow rate, and the integral value of the pressure loss measured using a semiconductor differential pressure gauge is taken as the air permeability resistance value. Then, the measurement of the air permeability resistance value is repeated multiple times (e.g., 5 times), and the average value is taken as the air permeability resistance value of the permeable pad 4.

[0094] Alternatively, a hydrophilic agent such as a surfactant can be coated onto the permeable pad 4 to perform a hydrophilic treatment. This hydrophilic treatment of the permeable pad 4 helps to inhibit urine residue from remaining in it. Furthermore, the permeable pad 4 can also contain an antibacterial agent containing silver ions. This antibacterial agent helps to suppress the odor of urine residue in the permeable pad 4. By using both hydrophilic agents and antibacterial agents to suppress urine odor, the permeable pad 4 can be used for a longer period, reducing the frequency of replacement.

[0095] The permeable pad 4 is colored differently from the front sheet 51. For example, to reduce the visual visibility of urine stains on the absorbent sheet 3, the permeable pad 4 is colored in a dark tone such as gray or black. Specifically, when the permeable pad 4 is viewed in the thickness direction overlaid on a standard white board, Brightness in the color system It can also be below 55.

[0096] Next, the steps for installing the absorbent sheet 3 and the permeable mat 4 onto the toilet body 2 will be described. First, by hand, the latch 38 of the middle frame 12 is opened outward in the width direction X, releasing the engagement between the latch 38 and the connecting portion 28 of the base plate 11. Then, the middle frame 12 is lifted and detached from the base plate 11. Next, the absorbent sheet 3 is placed on the base plate 11 such that the wing portion 3b of the absorbent sheet 3 is disposed on the outer edge portion 22 of the base plate 11. Next, the fitting protrusion 33 of the middle frame 12 is fitted into the fitting recess 27 of the base plate 11, thus installing the middle frame 12 onto the base plate 11. As a result, the wing portion 3b of the absorbent sheet 3 is held between the fitting recess 27 and the fitting protrusion 33. At this time, since the absorbent sheet 3 is pressed by the fitting protrusion 33 in a state where it is deeply inserted into the fitting recess 27, a strong frictional force is exerted on the absorbent sheet 3, thus firmly holding the absorbent sheet 3 in place.

[0097] Next, the latch 46 of the upper frame 13 is opened outward in the width direction X, releasing the latch 46 from the latch 38 of the middle frame 12. Then, the upper frame 13 is lifted and detached from the middle frame 12. Next, after placing the permeable pad 4 on the middle frame 12, the fitting protrusion 44 of the upper frame 13 is fitted with the fitting recess 34 of the middle frame 12, thereby installing the upper frame 13 onto the middle frame 12. As a result, the outer edge of the permeable pad 4 is held between the fitting recess 34 and the fitting protrusion 44. At this time, since the permeable pad 4 is pressed by the fitting protrusion 44 with a deeper insertion into the fitting recess 34, a strong frictional force is applied to the permeable pad 4, firmly holding the permeable pad 4 in place. In particular, since the maximum length of the fitting protrusion 44 is longer than the maximum length of the fitting protrusion 33, the retaining force achieved by the upper fitting structure 20 on the permeable pad 4 is greater than the retaining force achieved by the lower fitting structure 10 on the absorbent sheet 3.

[0098] In addition, the permeable pad 4 is pressed downward by the inner circumferential protrusion 43. As a result, a frictional force acts between the permeable pad 4 and the inner circumferential protrusion 43, further improving the holding force of the permeable pad 4.

[0099] When the absorbent sheet 3 and the permeable mat 4 are installed on the toilet body 2, the system toilet 1 can be used. When using the system toilet 1, the pet steps over the relatively narrow second upper frame edge 13B onto the permeable mat 4 to urinate. The pet's urine is absorbed by the absorbent sheet 3 through the permeable mat 4. After urinating, the pet steps over the second upper frame edge 13B to get off the system toilet 1.

[0100] The absorbent sheet 3 has high water retention capacity, allowing for multiple uses. For example, the absorbent sheet 3 can absorb three days' worth of pet urine. Furthermore, because a permeable pad 4 is incorporated into the absorbent sheet 3, it prevents urine absorbed by the absorbent sheet 3 from flowing back to the pet's legs, even with repeated use. Additionally, the permeable pad 4 has a brightness of 55 or less. Therefore, when a permeable pad 4 is placed on the absorbent pad 3, the visual visibility of urine stains on the absorbent pad 3 decreases, preventing pets from avoiding using the toilet due to their aversion to urine stains. Consequently, the frequency of replacing the absorbent pad 3 can be reduced.

[0101] Next, the procedure for replacing the absorbent pad 3 will be explained. If the pet urinates repeatedly and the absorbent pad 3 needs to be replaced, use your hand to pry open the latch 38 of the middle frame 12 outwards in the width direction X, releasing the latch 38 from the connection portion 28 of the base plate 11. Then, lift the middle frame 12 and detach it from the base plate 11. After replacing the used absorbent pad 3 with a new one, reinstall the middle frame 12 onto the base plate 11. In this way, the user can replace the absorbent pad 3 without directly contacting the permeable mat 4. Therefore, the absorbent pad 3 can be replaced without getting your hands dirty.

[0102] When replacing the permeable pad 4, the upper frame 13 is removed from the middle frame 12 by following the reverse steps as when installing the permeable pad 4, so that the permeable pad 4 can be removed separately from the system toilet 1 for replacement.

[0103] As explained above, the compressive energy (WC value) of the permeable pad 4 is set to 13 gf·cm / cm. 2 Above and 60 gf·cm / cm 2 Therefore, while providing the pet with a comfortable cushioning experience, it also prevents the pet's legs from coming into contact with the absorbent pad 3, thus preventing urine absorbed by the absorbent pad 3 from flowing back to the pet's legs. Thus, using this permeable pad 4 provides a clean and comfortable elimination environment for the pet.

[0104] The aforementioned permeable pad 4 is folded and stored inside the packaging 70. Figure 14 This is a schematic cross-sectional view of a package 70 containing multiple permeable pads 4. The permeable pads 4 are, for example, bags having a generally rectangular shape, and are made of, for example, synthetic resin, paper, or a combination thereof. An opening line (not shown) is formed on the package 70, along which the package 70 is opened to create an opening for removing the permeable pads 4 contained within it.

[0105] like Figure 14 As shown, the permeable pad 4 is folded into three sections and stored inside the packaging body 70 in an overlapping manner. When using the permeable pad 4, insert your finger into the packaging body 70 through the opening, grasp the permeable pad 4 and pull it out, thereby removing the permeable pad 4 from the packaging body 70.

[0106] Here, the inner surface 70a of the packaging body 70 is made of a resin film such as polyethylene, polypropylene, or polyethylene terephthalate. Because the inner surface 70a of the packaging body 70 is made of a resin film, the friction between the inner surface 70a and the permeable pad 4 is reduced, making it easy to remove the permeable pad 4 from the packaging body 70.

[0107] The permeable mat 4 and the toilet system 1 of various embodiments have been described above. However, the present invention is not limited to the embodiments described above, and various modifications can be made without changing the spirit of the invention. That is, it should be noted that the above embodiments are for illustrative purposes only and do not limit the scope of the present invention.

[0108] For example, in the toilet body 2 described above, a fitting recess 27 is formed in the bottom plate portion 11 and a fitting protrusion 33 is formed in the middle frame portion 12. Alternatively, a locking protrusion can be formed in the bottom plate portion 11 and a fitting recess can be formed in the middle frame portion 12. The middle frame portion 12 is connected to the bottom plate portion 11 by these locking protrusions and fitting recesses fitting together. Similarly, in the toilet body 2 described above, a fitting recess 34 is formed in the middle frame portion 12 and a fitting protrusion 44 is formed in the upper frame portion 13. Alternatively, a locking protrusion can be formed in the middle frame portion 12 and a fitting recess can be formed in the upper frame portion 13. The upper frame portion 13 is connected to the middle frame portion 12 by these locking protrusions and fitting recesses fitting together.

[0109] Furthermore, in the toilet body 2 described above, when viewed from the vertical direction Z, the fitting recess 27, fitting protrusion 33, fitting recess 34, and fitting protrusion 44 are rectangular in shape, but their shapes are not limited to rectangular. For example, the fitting protrusion 33 and fitting protrusion 44 may be cylindrical pins, and the fitting recess 27 and fitting recess 34 may be holes with a circular planar shape that engage with these pins. Alternatively, multiple fitting recesses 27, fitting protrusions 33, fitting recesses 34, and fitting protrusions 44 may be arranged along the periphery of the base plate portion 11, the middle frame portion 12, and the upper frame portion 13. The middle frame portion 12 is mounted on the base plate portion 11 and the upper frame portion 13 is mounted on the middle frame portion 12 by fitting the fitting protrusions 33 and 44 with the fitting recesses 27 and 34, respectively.

[0110] In the toilet body 2 described above, the length of the pair of first middle frame edges 12A in the width direction X is longer than the length of the pair of second middle frame edges 12B in the depth direction Y. However, it is also possible that the length of the pair of first middle frame edges 12A in the width direction X is shorter than the length of the pair of second middle frame edges 12B in the depth direction Y.

[0111] The material of the permeable pad 4 is not limited to polyurethane resin with a continuous bubble structure. The permeable pad 4 can be made of any material with a compressive energy of 13 gf·cm / cm. 2 Above and 60 gf·cm / cm 2 The following porous materials can be made of any material.
