[0007] Patent Document 2: Japanese Patent Application Publication No. 2014-68591 Summary of the Invention

[0008] Generally speaking, designed absorbent pads for pets are less noticeable than undesigned ones, improving urine concealment. Patent Documents 1 and 2 demonstrate that the absorbent pads for pets improve urine concealment throughout the entire absorbent body.

[0009] However, some pets sometimes urinate only in certain areas, rather than covering the entire absorbent surface. Pet absorbent pads used only in specific areas are sometimes not discarded but repositioned for continued use. However, as in Patent Document 1, if urine is highly concealed throughout the absorbent surface, it is difficult for the user to distinguish between urinated and non-urinated areas, making it difficult to determine when to replace the pad.

[0010] Therefore, it is desirable to have a pet absorbent tablet that allows users to easily distinguish between areas of urination and areas of non-urination, and to easily determine when to replace the tablet.

[0011] A pet absorbent sheet comprises: a thickness direction, a first direction orthogonal to the thickness direction, and a second direction orthogonal to both the thickness direction and the first direction; a surface sheet disposed on a surface side; a back sheet disposed on a back side; an absorbent body disposed between the surface sheet and the back sheet; and a colored portion disposed on the back side of the surface sheet, which is visually identifiable from the surface side of the surface sheet. The colored portion comprises a colored area and a non-colored area overlapping the absorbent body, with a plurality of the colored portions disposed in the colored area. The non-colored area is located between the colored areas in the first direction, and no colored portion is disposed in the non-colored area. The non-colored area is located over the entire area of ​​the absorbent body in the second direction.

[0012] Another technical solution for a pet absorbent sheet includes: a surface sheet disposed on a surface side; a back sheet disposed on a back side; an absorbent body disposed between the surface sheet and the back sheet; and a coloring portion that can be visually identified from the surface side of the surface sheet in the area overlapping with the absorbent body, wherein the coloring portion has a first coloring portion colored with a first color of the green family and a second coloring portion colored with a second color of the purple family.

[0013] Another technical solution for a pet absorbent sheet includes: a surface sheet disposed on a surface side; a back sheet disposed on a back side; an absorbent body disposed between the surface sheet and the back sheet; and a coloring portion disposed on the back side of the surface sheet in an area overlapping with the absorbent body, and the coloring portion can be visually identified from the surface side of the surface sheet. The coloring portion has a pet face pattern representing the face of the pet to which the product is intended. The pet face pattern includes a first pet face pattern colored with a first color and a second pet face pattern colored with a second color different from the first color. The degree of difference between the first color and the second color is such that they are offset by more than two colors in a 24-color swatch based on the Oswald color wheel.

[0014] Another technical solution for a pet absorbent sheet includes: a surface sheet disposed on a surface side; a back sheet disposed on a back side; an absorbent body disposed between the surface sheet and the back sheet; and a coloring portion disposed on the back side of the surface sheet in an area overlapping with the absorbent body, and the coloring portion can be visually identified from the surface side of the surface sheet, wherein the coloring portion has a pet face pattern representing the face of a cat, which is the object of use, and does not have a non-object pattern representing a pet other than the object of use.

[0023] (1) Overview of the implementation method

[0024] Based on the description in this specification and the accompanying drawings, at least the following matters are made clear.

[0025] A pet absorbent sheet comprises: a thickness direction, a first direction orthogonal to the thickness direction, and a second direction orthogonal to both the thickness direction and the first direction; a surface sheet disposed on a surface side; a back sheet disposed on a back side; an absorbent body disposed between the surface sheet and the back sheet; and a colored portion disposed on the back side of the surface sheet, which is visually identifiable from the surface side of the surface sheet. The colored portion comprises a colored area and a non-colored area overlapping the absorbent body, with a plurality of the colored portions disposed in the colored area. The non-colored area is located between the colored areas in the first direction, and no colored portion is disposed in the non-colored area. The non-colored area is located over the entire area of ​​the absorbent body in the second direction.

[0026] Some pets sometimes urinate not across the entire absorbent pad, but rather in a specific area (e.g., a colored area on one side). In this case, they may not urinate in other areas (e.g., the colored area on the other side), or the amount of urine may be less. When using the absorbent pad, the colored area can be used to conceal the urine. Furthermore, when changing the pad, the colored area on the side with more urine can be compared to the colored area on the side with less urine. In this case, colored areas are provided on both sides of the non-colored area, and the colored areas on one side and the other side are separated by the non-colored areas. By comparing the colored areas on both sides separated by the non-colored areas, it is easy to compare the colored areas on both sides. Therefore, the user can easily determine whether to change the direction when using only one colored area, or to change the pad when using both colored areas. Additionally, there are non-colored areas without colored parts, so urine traces are not easily concealed by the colored parts in these areas. Therefore, the user can also easily determine whether the pet has urinated on the absorbent pad.

[0027] According to a preferred technical solution, the uncolored region may extend across the center of the absorber in a first direction. The uncolored region is located at the center of the absorber in the first direction. The uncolored region is easily visible, allowing the user to easily grasp its location and thus more easily determine when to replace the absorber.

[0028] According to a preferred technical solution, the length of the uncolored region in the first direction may be longer than the length of the colored portion in the first direction. Because the length of the uncolored region in the first direction is longer than the length of the colored portion in the first direction, it is easier to distinguish the intervals between colored portions from the uncolored region. Therefore, it is easier to achieve the effect of using the uncolored region to truncate the colored regions on both sides.

[0029] According to a preferred technical solution, the length of the uncolored region in the first direction may be longer than the length of each colored region in the first direction. Since the length of the uncolored region in the first direction is longer than the length of the colored region in the first direction, it is easier to achieve the effect of distinguishing each colored region using the uncolored region.

[0030] According to a preferred technical solution, a second uncolored region may be provided on the outer side of the colored region in the first direction in the area overlapping with the absorber. In this second uncolored region, the colored portion is not disposed throughout the entire area of ​​the absorber in the second direction. Uncolored regions and a second uncolored region are provided on both sides of the colored region. The colored portion of the colored region is more conspicuous, making it easier to compare the colored regions on both sides.

[0031] According to a preferred technical solution, the colored portion may have a first colored portion colored with a first color and a second colored portion colored with a second color different from the first color. The area ratio of the second colored portion relative to the first colored portion in the colored area on one side is different from the area ratio of the second colored portion relative to the first colored portion in the colored area on the other side. Because the area ratio of the second colored portion relative to the first colored portion differs between the colored areas on one side and the colored area on the other side, the user can distinguish between the colored areas on one side and the colored area on the other side by the difference in the color composition ratio, making it easy to compare the colored areas on both sides.

[0032] According to a preferred technical solution, the colored portions of one side of the colored area and the colored area of ​​the other side are configured such that at least one of the colors and shapes of the colored portions on any straight line extending along the first direction through one of the colored portions is different. When comparing the colored areas on one side and the colored areas on the other side, the user moves their gaze along the first direction, alternately visually identifying the colored areas on one side and the colored areas on the other side. At this time, adjacent colored portions in the first direction are different, so the user can distinguish the colored areas on one side and the colored areas on the other side by the difference in color and shape of the colored portions, making it easy to compare the colored areas on both sides.

[0033] Another technical solution for a pet absorbent sheet includes: a surface sheet disposed on a surface side; a back sheet disposed on a back side; an absorbent body disposed between the surface sheet and the back sheet; and a coloring portion that can be visually identified from the surface side of the surface sheet in the area overlapping with the absorbent body, wherein the coloring portion has a first coloring portion colored with a first color of the green family and a second coloring portion colored with a second color of the purple family.

[0034] Patent Document 1 describes a design consisting of a colored or chromatic design. Generally, pet absorbent pads with a design are less noticeable of urine compared to those without, improving urine concealment. However, for some designs, the design and urine stains are similar, potentially leading users to mistakenly believe they have been used even before application. Furthermore, for some designs, urine and the design can be confused, potentially preventing the design from enhancing urine concealment. Therefore, a pet absorbent pad capable of distinguishing and identifying urine and the colored portion, and utilizing the colored portion to improve urine concealment, is desired.

[0035] This technical solution provides an absorbent pad for pets that can distinguish and identify urine and stained areas, using the stained areas to improve the concealment of urine. Generally, healthy urine is yellowish, while unhealthy urine is reddish. The first stained area (green) and the second stained area (purple) are easier to distinguish and identify than yellow and red. This prevents users from mistaking stained areas for urine stains before use. Furthermore, the easily distinguishable colors of both healthy and unhealthy urine allow users to easily monitor their urine's condition. Additionally, the ease of distinguishing and identifying urine and stained areas allows the stained areas to conceal urine stains, improving urine concealment.

[0036] According to a preferred technical solution, the first coloring part can be a color based on the RGB color system where the R value is in the range of 0-128, the G value is in the range of 165-191, and the B value is in the range of 90-113. The R, G, and B values ​​of the first coloring part do not overlap with the colors of healthy and unhealthy urine, making it easy to distinguish from urine.

[0037] According to a preferred technical solution, the second coloring part can be a color based on the RGB color system where the R value is in the range of 127-186, the G value is in the range of 65-91, and the B value is in the range of 136-151. The R and B values ​​of the second coloring part do not overlap with the colors of healthy and unhealthy urine, making it easy to distinguish from urine.

[0038] According to a preferred technical solution, the colored portion may be arranged along a designed contour, and a non-colored portion may be provided in the area surrounded by the colored portion. When urination occurs in the non-colored portion, the urine and the colored portion can be compared. Furthermore, since the colored portion is arranged surrounding the non-colored portion, the diffusion of urine can be monitored using the colored portion. Therefore, by monitoring the amount of urine, the pet's health status can also be assessed.

[0039] According to a preferred technical solution, the first coloring portion may have a first pet pattern representing the pet used to identify the intended pet and a first auxiliary pattern representing other than the pet. The second coloring portion may have a second pet pattern representing the pet used to identify the intended pet and a second auxiliary pattern representing other than the pet. The second auxiliary pattern is arranged in or near the area overlapping with the first pet pattern, and the first auxiliary pattern is arranged in or near the area overlapping with the second pet pattern. The first pet pattern and the second auxiliary pattern are arranged close together, thus allowing for comparison between urine and both the first and second coloring portions. This makes it easy to determine whether the pet is healthy or unhealthy. Furthermore, the user can visually identify the first and second pet patterns to understand the intended pet. Therefore, even when multiple pets are present, it is easy to identify the intended pet and its health status. In addition, the pet pattern and auxiliary pattern are integrated, thus improving design and enhancing the concealment of urine.

[0040] According to a preferred technical solution, the maximum size of the first pet pattern may be larger than the maximum size of the second auxiliary pattern, and the maximum size of the second pet pattern may be larger than the maximum size of the first auxiliary pattern. The first and second pet patterns are easily visible, allowing the user to easily identify the pet being used. Therefore, even when multiple pets are present, it is easy to identify the pet being used and to monitor its health status.

[0041] According to a preferred technical solution, the absorbent may have a peripheral colored portion that is visually identifiable from the surface side of the surface sheet, and the peripheral colored portion has either the first color or the second color. Because the peripheral colored portion has either the first color or the second color, it can make the first or second colored portion more conspicuous. This further improves the concealment effect of the colored portion on urine.

[0042] Another technical solution for a pet absorbent sheet includes: a surface sheet disposed on a surface side; a back sheet disposed on a back side; an absorbent body disposed between the surface sheet and the back sheet; and a coloring portion disposed on the back side of the surface sheet in an area overlapping with the absorbent body, and the coloring portion can be visually identified from the surface side of the surface sheet. The coloring portion has a pet face pattern representing the face of the pet to which the product is intended. The pet face pattern includes a first pet face pattern colored with a first color and a second pet face pattern colored with a second color different from the first color. The degree of difference between the first color and the second color is such that they are offset by more than two colors in a 24-color swatch based on the Oswald color wheel.

[0043] For users who own multiple pets, it is desirable to use absorbent pads specifically designed for each pet. Specifically, absorbent pads for cats and absorbent pads for dogs should be used separately. However, the absorbent pad in Patent Document 2 displays pet footprints, making it difficult for users to determine whether it is for dogs or cats. Furthermore, if cat footprints are displayed on a dog-specific absorbent pad, users may mistakenly identify the intended use. Therefore, a absorbent pad for pets that is easy for users to identify is desired.

[0044] The absorbent sheet for pets in this technical solution is designed so that users can easily identify the pet. By featuring a first and a second pet face pattern, its decorative appeal is enhanced, attracting the user's attention. Furthermore, the first and second pet face patterns are different colors, preventing them from being perceived as a single unit and ensuring each is clearly visible. Users can easily identify the pet by visually recognizing the face patterns.

[0045] According to a preferred technical solution, the colored portion may not have non-object patterns representing pets other than the intended pet. Users can easily identify the intended pet by visually recognizing the pet's face pattern. Furthermore, since it lacks non-object patterns, it can be used without confusing the intended pet even when multiple intended pets are present.

[0046] According to a preferred technical solution, the colored portion may have the pet face pattern and non-object patterns identifying pets other than the intended user, wherein the number of pet face patterns is more than twice the number of non-object patterns. Users can easily identify the intended pet by visually recognizing the pet face pattern. Since the number of pet face patterns is more than twice the number of non-object patterns, users can easily identify the pet face pattern as the intended user, thus preventing the mistake of using the wrong pet. Even when there are multiple intended users, users can use the pet without confusion.

[0047] According to a preferred technical solution, the maximum size of the pet face pattern may be larger than the maximum size of the non-object pattern. The pet face pattern is more conspicuous than the non-object pattern, allowing users to easily identify the pet being used by visually recognizing the pet face pattern.

[0048] According to a preferred technical solution, the color of the non-object pattern may be different from the color of the pet face pattern located in the nearest position, such that the difference is more than two shades apart in a 24-color chart classified according to the Oswald color wheel. This allows users to easily distinguish and identify the pet face pattern and the non-object pattern. Users can easily identify the pet being used by visually recognizing the pet face pattern.

[0049] According to a preferred technical solution, the pet face pattern may represent the face of a cat, the object of use. Users can easily identify the cat as the object of use by visually recognizing the pet face pattern.

[0050] According to a preferred technical solution, the absorber may have a surrounding area disposed around it, and this surrounding area may have an outer peripheral coloring portion that is visually recognizable from the surface side of the surface sheet. The outer peripheral coloring portion is a similar color to the first color, meaning that the similarity is within the range of the same color card or a hue number differing by only one in the 24-color chart classified according to the Oswald color wheel. This allows the outer peripheral coloring portion to be integrated with the first color pattern, enhancing its decorative appeal and attracting the user's attention. Furthermore, by integrating the outer peripheral coloring portion with the first color pattern, the second color pattern becomes relatively more conspicuous. Users can easily identify their pet by recognizing either the first or second color pattern.

[0051] Another technical solution for a pet absorbent sheet includes: a surface sheet disposed on a surface side; a back sheet disposed on a back side; an absorbent body disposed between the surface sheet and the back sheet; and a coloring portion disposed on the back side of the surface sheet in an area overlapping with the absorbent body, and the coloring portion can be visually identified from the surface side of the surface sheet, wherein the coloring portion has a pet face pattern representing the face of a cat, which is the object of use, and does not have a non-object pattern representing a pet other than the object of use.

[0052] Users can easily identify the cat as the target pet by visually recognizing the pet's face pattern. Furthermore, there are no non-target pet patterns to represent other pets besides the cat, so even when there are multiple target pets, users can use the device without confusion.

[0053] According to a preferred technical solution, the number of pet face patterns may be more than 50% of the total number of patterns. Among all patterns, pet face patterns are more easily noticed, allowing users to easily identify the pet by visually recognizing the pet face pattern.

[0054] According to a preferred technical solution, the colored portion may have auxiliary patterns representing things other than the pet, and the number of pet face patterns is greater than the number of auxiliary patterns. The pet face patterns are more easily visible than the auxiliary patterns, allowing the user to easily identify the pet by visually recognizing the pet face patterns.

[0055] According to a preferred technical solution, the maximum size of the pet face pattern may be larger than the maximum size of the auxiliary pattern. The pet face pattern is more conspicuous than the auxiliary pattern, allowing users to easily identify the pet through visual recognition of the pet face pattern.

[0056] According to a preferred technical solution, the color of the auxiliary pattern may be different from the color of the pet face pattern located in the nearest position, such that the difference is more than two colors different from each other in a 24-color chart classified according to the Oswald color wheel. This allows users to easily distinguish and identify the pet face pattern and the auxiliary pattern. Users can easily manage their pet by visually recognizing the pet face pattern.

[0057] According to a preferred technical solution, the pet face pattern can be a pattern representing the entire body, including the face of the pet being used. By showing the entire body through the pet face pattern, the user can more easily grasp the pet. Users can easily grasp the pet being used by visually recognizing the pet face pattern.

[0058] According to a preferred technical solution, the surface may have a background portion located around the colored portion in an area overlapping with the absorber and visually recognizable from the surface side of the surface sheet. The color of the pet face pattern differs from the color of the background portion, with the difference being at least two colors different from each other in a 24-color chart classified according to the Oswald color wheel. The pet face pattern is more conspicuous than the background portion, making it easier for the user to identify. The user can easily identify the pet by visually recognizing the pet face pattern.

[0059] (2) Structure of absorbent pads for pets

[0060] Hereinafter, with reference to the accompanying drawings, the absorbent sheet for pets according to the first embodiment will be described. In the following description of the drawings, the same or similar parts will be labeled with the same or similar reference numerals. It should be noted that the drawings are schematic, and the scale of each dimension may differ from the actual scale. Therefore, specific dimensions should be determined by referring to the following description. Furthermore, the drawings may contain parts with different dimensional relationships or scales. In this specification, "pet" broadly includes vertebrates and invertebrates, typically including cats, dogs, rabbits, hamsters, etc. The absorbent sheet for pets according to this embodiment is an absorbent sheet for cats.

[0061] Figure 1 This is a top view of the pet absorbent sheet of the first embodiment, viewed from the excretory side. Figure 2 It's a pet absorbent tablet along... Figure 1 A schematic cross-sectional view of line AA shown. Figure 3 yes Figure 1 An enlarged top view of part B. The pet absorbent sheet 10 is a generally flat sheet. One side of the pet absorbent sheet 10 is the excrement surface that receives pet excrement. In this embodiment, the surface constituting the excrement surface is designated as surface 101, and the surface constituting the non-excrement surface is designated as back surface 102 for description. Figure 2 In the figure, T1 represents the surface side and T2 represent the back side in the thickness direction T.

[0062] The absorbent sheet for pets has a first direction D1 and a second direction D2 orthogonal to the thickness direction T. The first direction D1 and the second direction D2 are orthogonal to each other. The first direction D1 and the second direction D2 are directions extending along a plane. In this embodiment, the first direction D1 is the length direction when viewed from above, and the second direction D2 is the width direction orthogonal to the length direction. Alternatively, in a modified example, the first direction D1 may be the width direction when viewed from above, and the second direction D2 may be the length direction.

[0063] The pet absorbent sheet 10 has a surface sheet 12 disposed on the surface side T1, a back sheet 14 disposed on the back side T2, and an absorbent body 20. The absorbent body 20 is disposed between the surface sheet 12 and the back sheet 14. The surface sheet 12 can be a liquid-permeable sheet through which liquids such as pet excrement can pass. The liquid-permeable sheet can be made of, for example, a liquid-permeable nonwoven fabric or an open membrane. The back sheet 14 can be a liquid-impermeable sheet through which liquids such as pet excrement cannot pass. The back sheet 14 is not particularly limited and can be made of, for example, a resin film. In this embodiment, the entire back sheet 14 is colored. The back sheet 14 can also be colored with either the first color or the second color described later.

[0064] A portion of the back sheet 14 extends outward from the absorbent body 20. The colored portion of the back sheet disposed on the outer periphery 18 of the pet absorbent sheet 10 is visually identifiable from the surface side T1, constituting the "peripheral colored portion" of the present invention. The peripheral colored portion is visually identifiable from the surface side of the surface sheet 12 around the absorbent body. The user can visually identify the portion of the back sheet 14 located on the outer periphery 18 through the surface sheet 12.

[0065] The absorbent 20 may include an absorbent core 30 and a core-cladding layer 33 covering the absorbent core 30. The core-cladding layer 33 may include a first core-cladding layer 33a covering the surface side T1 of the absorbent core 30 and a second core-cladding layer 33b covering the back side T2 of the absorbent core 30. The absorbent core 30 is not particularly limited and may contain a hydrophilic fiber layer such as pulp and a superabsorbent polymer (SAP), or a combination thereof. The core-cladding layer 33 is not particularly limited and may, for example, be made of liquid-permeable cotton paper.

[0066] The pet absorbent sheet 10 has a colored portion 80 in the area overlapping with the absorbent core 20, which is visually identifiable from the surface side T1 of the surface sheet 12. The colored portion 80 is disposed on the back side T2 of the surface sheet 12. In this embodiment, the colored portion 80 is printed on the surface side T1 of the first core layer 33a. In a modified example, the colored portion 80 may be provided on the back side of the surface sheet 12, or on the surface side T1 of the absorbent core 30, or a second sheet may be disposed between the surface sheet 12 and the absorbent core 20, and the colored portion may be provided on the surface side T1 of the second sheet.

[0067] The coloring section 80 may have a pet pattern 81 that identifies the pet being used, and an auxiliary pattern 84 that represents other things besides the pet. The pet pattern 81 is a concept that includes not only a pattern representing the pet's face, but also a pattern representing the pet's body and a pattern representing its favorite food. The auxiliary pattern 84 is a pattern that represents other things besides the pet, and can be any pattern such as a heart or a star.

[0068] The maximum size in the first direction D1 of pet pattern 81 can be larger than the maximum size in the first direction D1 of auxiliary pattern 84. Furthermore, the maximum size in the second direction D2 of pet pattern 81 can be larger than the maximum size in the second direction D2 of auxiliary pattern 84. Pet pattern 81 is more conspicuous than auxiliary pattern 84, allowing the user to easily identify the pet being used through visual recognition of pet pattern 81. Users can easily identify the cat as the pet being used using pet pattern 81, preventing the mistake of using the wrong pet even when multiple pets are present.

[0069] The number of pet patterns 81 can be more than 50% of the total number of patterns. Among all patterns, pet patterns 81 are more eye-catching, allowing users to easily identify the pet through visual recognition. Furthermore, the number of pet patterns 81 can be more than the number of auxiliary patterns 84. Pet patterns 81 are more eye-catching than auxiliary patterns 84, allowing users to easily identify the pet through visual recognition.

[0070] A colored region R1 and a non-colored region R2 may be provided in the area overlapping with the absorbent body of the pet absorbent sheet 10. Multiple colored portions 80 are arranged in the colored region R1, and the non-colored region R2 is located between the colored regions R1 in the first direction D1, without any colored portions 80. The colored region R1 and the non-colored region R2 cover the entire area of ​​the absorbent body 20 in the second direction D2. The non-colored region R2 is the entire area of ​​the absorbent body 20 in the second direction D2 where no colored portions 80 are provided. The colored region R1 is the area where any colored portion 80 is provided on any imaginary line extending along the second direction D2 of the absorbent body 20. The non-colored region R2 is sandwiched between the colored regions R1 in the first direction D1. Both the colored region R1 and the non-colored region R2 overlap with the absorbent core 30 of the absorbent body 20 when viewed from above.

[0071] Some pets do not urinate throughout the entire absorbent, but only in a specific area (e.g., the colored area R1 on one side). In this case, they may not urinate in other areas (e.g., the colored area R1 on the other side) or the amount of urine may be reduced. When using the absorbent, the colored portion 80 of this colored area R1 can be used to conceal the urine. Furthermore, when changing the absorbent, the colored area R1 on the side with more urine and the colored area R1 on the other side with less urine can be compared. In this case, colored areas R1 are provided on both sides of the non-colored area R2, and the colored areas R1 on one side and the other side are interrupted by the non-colored area R2. By comparing the colored areas R1 on both sides separated by the non-colored area R2, it is easy to compare the colored areas R1 on both sides. Therefore, the user can easily determine whether to use only one colored area R1 and change the absorbent, or to use both colored areas R1 and change the absorbent. Additionally, there is a non-colored area R2 without the colored portion 80, so urine traces are not easily concealed by the colored portion 80 in this non-colored area R2. Therefore, users can easily tell whether urination has occurred on the pet absorbent pad 10.

[0072] The uncolored region R2 can span the center 20LC in the first direction D1 of the absorber 20. The uncolored region R2 is provided at the center 20LC in the first direction D1 of the absorber 20. The uncolored region R2 is easily visible, and the user can easily grasp the uncolored region R2 and more easily grasp the replacement time of the absorber.

[0073] The length L2 of the uncolored region R2 in the first direction D1 can be longer than the length L80 of the colored portion 80 in the first direction D1. Since the length of the uncolored region R2 in the first direction D1 is longer than the length of the colored portion 80 in the first direction D1, it is easier to distinguish the intervals between the colored portions 80 from the uncolored region R2. Therefore, it is easier to achieve the effect of using the uncolored region R2 to cut off the colored regions R1 on both sides. Furthermore, in a structure having multiple colored portions 80 of different sizes, the length of the colored portion 80 in the first direction D1 is set to the length of the colored portion 80 with the longest length in the first direction D1. The length L2 of the uncolored region R2 in the first direction D1 can be longer than the length L1 of each colored region R1 in the first direction D1. Since the length L2 of the uncolored region R2 in the first direction D1 is longer than the length L1 of the colored region R1 in the first direction D1, it is easier to achieve the effect of using the uncolored region R2 to distinguish each colored region R1.

[0074] The length L1 in the first direction of the colored region R1 located on one side of the center 20LC in the first direction D1 relative to the absorber 20 can be different from the length L1 in the first direction D1 of the colored region R1 located on the other side relative to the center 20LC. This makes it easy to distinguish each colored region R1 and to compare the colored regions R1 on both sides. As a result, the user can easily determine whether to use only one side of the colored region R1 and change the orientation, or to use both sides of the colored region R1 and change the orientation.

[0075] In the area overlapping with the absorber 20, on the outer side of the first direction D1 of the colored region R1, a second uncolored region R3 may be provided, which is an area in the second direction D2 of the absorber 20 where the entire area is not colored by the colored portion 80. Uncolored regions R2 and the second uncolored region R3 are provided on both sides of the colored region R1. The colored portion 80 of the colored region R1 is more conspicuous, making it easier to contrast the colored regions R1 on both sides.

[0076] The length L3 of the second uncolored region R3 in the first direction D1 can be shorter than the length L1 of the colored region R1 in the first direction D1. By making the colored region R1 conspicuous, the user can easily compare the two colored regions R1. Thus, the user can easily determine whether to use only one colored region R1 and change the orientation, or to use both colored regions R1 and change the orientation.

[0077] The coloring section 80 may have a first coloring section 80A colored with a first color and a second coloring section 80B colored with a second color different from the first color. Specifically, the pet pattern may have a first pet pattern 81A colored with the first color and a second pet pattern 81B colored with the second color. Additionally, the auxiliary pattern 84 may have a first auxiliary pattern 84A colored with the first color and a second auxiliary pattern 84B colored with the second color. The first coloring section 80A has a first pet pattern 81A and a first auxiliary pattern 84A. The second coloring section 80B has a second pet pattern 81B and a second auxiliary pattern 84B. That is, the first pet pattern 81A and the first auxiliary pattern 84A are colored with the same color. Similarly, the second pet pattern 81B and the second auxiliary pattern 84B are colored with the same color. Furthermore, the first pet pattern 81A and the first auxiliary pattern 84A can be primarily colored using the first color, or they can be partially colored using colors other than the first color. Similarly, the second pet pattern 81B and the second auxiliary pattern 84B can be primarily colored using the second color, or they can be partially colored using colors other than the second color. The state of being colored by the primary color refers to the state where more than 90% of the pattern is colored using the primary color.

[0078] The area ratio of the second colored portion 80B relative to the first colored portion 80A in one colored area R1 can be different from that in the other colored area R1. Specifically, the colored portion formed by the first pet pattern 81A and the first auxiliary pattern 84A can be designated as the first colored portion 80A, and the colored portion formed by the second pet pattern 81B and the second auxiliary pattern 84B can be designated as the second colored portion 80B, and the area ratios can be compared. Since the area ratio of the second colored portion 80B relative to the first colored portion 80A differs between the colored areas on one side and the other side, users can distinguish between the colored areas on one side and the other side based on the different proportions of the colors, making it easy to compare the colored areas on both sides.

[0079] Appropriately, the area of ​​the first colored portion 80A of one colored region R1 may differ from the area of ​​the first colored portion of the other colored region R1. The total area of ​​the first pet pattern 81A of one colored region R1 may differ from the total area of ​​the first pet pattern 81A of the other colored region R1, and the total area of ​​the second pet pattern 81B of one colored region R1 may differ from the total area of ​​the second pet pattern 81B of the other colored region R1. Similarly, the total area of ​​the first auxiliary pattern 84A of one colored region R1 may differ from the total area of ​​the first auxiliary pattern 84A of the other colored region R1, and the total area of ​​the second auxiliary pattern 84B of one colored region R1 may differ from the total area of ​​the second auxiliary pattern 84B of the other colored region R1. Because of this structure, since the patterns are different in the coloring areas on one side and the other side, users can distinguish between the coloring areas on one side and the other side based on the different patterns, making it easy to compare the coloring areas on both sides.

[0080] The number of first colored parts 80A in one colored area R1 can be different from the number of first colored parts 80A in the other colored area R1. Similarly, the number of second colored parts 80B in one colored area R1 can be different from the number of second colored parts 80B in the other colored area R1. Appropriately, the number of first pet patterns 81A in one colored area R1 can be different from the number of first pet patterns 81A in the other colored area R1, and the number of second pet patterns 81B in one colored area R1 can be different from the number of second pet patterns 81B in the other colored area R1. Likewise, the number of first auxiliary patterns 84A in one colored area R1 can be different from the number of first auxiliary patterns 84A in the other colored area R1, and the number of second auxiliary patterns 84B in one colored area R1 can be different from the number of second auxiliary patterns 84B in the other colored area R1. Because of this structure, since the patterns are different in the coloring areas on one side and the other side, users can distinguish between the coloring areas on one side and the other side based on the different patterns, making it easy to compare the coloring areas on both sides.

[0081] The color and shape of the colored portion of one side of the colored area R1 and the colored portion of the other side of the colored area R1 are arranged on any straight line FL extending along an arbitrary straight line passing through a colored portion and along a first direction, and at least one of these two colors may be different. When the user compares the colored area R1 on one side and the colored area R1 on the other side, the user moves the line of sight along the first direction D1 and visually identifies the colored area R1 on one side and the colored area R1 on the other side alternately. At this time, the adjacent colored portions in the first direction are different, so the user can distinguish the colored area on one side and the colored area on the other side based on the difference in color and shape of the colored portions, making it easy to compare the colored areas on both sides.

[0082] Specifically, such as Figure 1 As shown, a shaded region R1 is disposed on one side of an arbitrary straight line FL1 extending along the first direction (located in...). Figure 1 The second pet pattern 81B of the lower colored area R1 and the colored area R1 on the other side (located in Figure 1 The second pet pattern 81B is shown in the upper colored area R1. These patterns have the same color but different shapes (the pattern on one side is a sitting cat, and the pattern on the other side is a lying cat). Additionally, the first pet pattern 81A of the colored area R1 on one side and the second pet pattern 81B of the colored area R1 on the other side are arranged on any straight line FL2 extending along the first direction. These patterns have different colors and different shapes.

[0083] The first and second colors can be different colors; there are no particular restrictions. The degree of difference between the first and second colors can be more than two shades apart in a 24-color chart based on the Oswald color wheel. Additionally, the first color can be a green-based color, and the second color can be a purple-based color. That is, the first pet pattern 81A and the first auxiliary pattern 84A constituting the first coloring part 80A can be colored using the first green-based color, and the second pet pattern 81B and the second auxiliary pattern 84B constituting the second coloring part 80B can be colored using the second purple-based color. Generally, the urine of a healthy pet is yellowish, while the urine of an unhealthy pet is reddish. The green-based first coloring part 80A and the purple-based second coloring part 80B are easier to distinguish and identify than yellowish and reddish colors. Therefore, users can easily distinguish and identify the coloring part 80 and urine, preventing the possibility of mistakenly identifying the coloring part 80 as urine traces. Therefore, users are less likely to mistake a pet absorbent tablet before use for one after use.

[0084] Furthermore, users can easily distinguish and identify urine and the stained area 80, thus focusing their attention on the stained area 80. The stained area 80 can be used to enhance the design of absorbent pads for pets. In addition, by making the stained area 80 conspicuous, urine can be made relatively inconspicuous, concealing urine traces and improving urine concealment.

[0085] Here, the color of urine in a healthy state is based on the RGB color system, with R values ​​ranging from 236 to 255, G values ​​from 208 to 241, and B values ​​from 29 to 86. Conversely, the color of urine in an unhealthy state is based on the RGB color system, with R values ​​ranging from 213 to 223, G values ​​from 84 to 89, and B values ​​from 53 to 69. The first coloring part 80A can be a color based on the RGB color system, with R values ​​ranging from 0 to 128, G values ​​from 165 to 191, and B values ​​from 90 to 113. The R, G, and B values ​​of the first coloring part do not overlap with the colors of healthy and unhealthy urine, making it easy to distinguish from other urine. The second coloring part 80B can be a color based on the RGB color system, with R values ​​ranging from 127 to 186, G values ​​from 65 to 91, and B values ​​from 136 to 151. The R and B values ​​of the second coloring part do not overlap with the colors of healthy and unhealthy urine, making it easy to distinguish from other urine.

[0086] These RGB values ​​can be measured, for example, using a commercially available colorimeter. The color of the colored portion in this invention is not the color of the colored sheet itself, but rather the color as perceived visually through the surface sheet. When measuring the RGB values, measurements are taken from the surface side of the pet absorbent sheet. The color difference relative to a white reference plate is measured using the first color, the second color, the color of urine in a healthy state, and the color of urine in an unhealthy state, all falling within the aforementioned RGB value range. The color difference is ΔL, Δa, and Δb relative to the (L*a*b*) color space of the white reference plate. The measurement results are shown in Table 1. The color difference relative to the white reference plate can be calculated by measuring the lab value of the white reference plate and the lab value of the object sample, respectively. The white reference plate is set to lab0 in (X93.19, Y95.20, Z112.28). For example, a Konica Minolta CR-300 colorimeter can be used as the light source for the measuring device, and a C light source (International Commission on Illumination (CIE) specification) can be used. The diameter of the measuring window of the measuring device is 40 mm. Here, L represents the value of brightness, and a and b are the chromaticity coordinates in the plane. If the Lab values ​​of the white reference plate are set to L0, a0, and b0, and those of the object sample are set to L1, a1, and b1, then calculations can be performed using ΔL = L0 - L1, Δa = a0 - a1, and Δb = b0 - b1.

[0087] [Table 1]

[0088]

[0089] The colored sections 80 can be arranged along the designed outline, and non-colored sections 85 are provided in the area surrounded by the colored sections 80. Specifically, the pet pattern 81 is arranged along the outline of a cat, and the auxiliary pattern 84 is arranged along the outline of a butterfly. Non-colored sections 85 are provided in the area surrounded by the colored sections 80 that constitute this outline. When urination occurs in the non-colored sections 85, the urine and the colored sections 80 can be compared. In addition, since the colored sections 80 are arranged around the non-colored sections 85, the diffusion of urine can be monitored using the colored sections 80. Thus, by monitoring the amount of urine, the health status of the pet can also be monitored.

[0090] like Figure 3 As shown, a second auxiliary pattern 84B can be placed in or near the area overlapping with or near the first pet pattern 81A, and a first auxiliary pattern 84A can be placed in or near the area overlapping with or near the second pet pattern 81B. Here, "placed near" means that the distance between the two patterns is 10mm or less. Because the first pet pattern 81A and the second auxiliary pattern 84B are placed close together, and the second pet pattern 81B and the first auxiliary pattern 84A are placed close together, it is possible to compare both the first coloring portion 80A and the second coloring portion 80B with urine. This makes it easy to determine whether the pet is healthy or unhealthy.

[0091] Furthermore, users can visually identify the first pet pattern 81A and the second pet pattern 81B, thus understanding the pets they are using. Therefore, even when multiple pets exist, it is easy to understand the pet in question. Even if the urine color differs depending on whether the pet is healthy or unhealthy, understanding the pet makes it easy to accurately assess the health status of each individual pet.

[0092] Furthermore, the integrated design of pet pattern 81 and auxiliary pattern 84 enhances the design and improves the concealment of urine. Appropriately, the distance L13 between the first assembly (combining the first pet pattern 81A and the second auxiliary pattern 84B) and the second assembly (combining the second pet pattern 81B and the first auxiliary pattern 84A) can be longer than the distance L11 between the first pet pattern 81A and the second auxiliary pattern 84B, and longer than the distance L12 between the second pet pattern 81B and the first auxiliary pattern 84A. This facilitates easy identification of the first assembly (combining the first pet pattern 81A and the second auxiliary pattern 84B) and the second assembly (combining the second pet pattern 81B and the first auxiliary pattern 84A), enabling the integration of pet pattern 81 and auxiliary pattern 84.

[0093] It is permissible that the maximum size of the first pet pattern 81A is larger than the maximum size of the second auxiliary pattern 84B, and the maximum size of the second pet pattern 81B is larger than the maximum size of the first auxiliary pattern 84A. The first pet pattern 81A and the second pet pattern 81B are easily visible, allowing the user to easily monitor the pet being used. Therefore, even when multiple pets are present, it is easy to monitor the pet being used and its health status.

[0094] The peripheral coloring portion 87 can have a first color or a second color. Because the peripheral coloring portion 87 has a first color or a second color, it can make the first coloring portion 80A or the second coloring portion 80B more conspicuous. This further enhances the concealment effect of the coloring portion 80 on urine.

[0095] Next, based on Figure 4 Description of the second embodiment of the pet absorbent sheet 10X. Figure 4 This is a top view of the pet absorbent sheet according to the second embodiment, viewed from the excretory side. Furthermore, in the description of the second embodiment, the same reference numerals are used for the same structures as in the first embodiment described above, and descriptions are omitted.

[0096] The coloring part 80X in the second embodiment has a pet pattern 811 but no auxiliary patterns. Users can easily identify the pet being used by visually recognizing the pet pattern 811. Furthermore, since there are no auxiliary patterns, the pet pattern 811 is more conspicuous and easier to identify the user.

[0097] The pet pattern 811 includes a first pet pattern 811A colored with a first color and a second pet pattern 811B colored with a second color. The first pet pattern 811A and the second pet pattern 811B are not only outlines but also fill patterns. The pet patterns are more easily visible, allowing users to easily compare the colored areas on both sides. Therefore, users can easily determine whether to use only one side of the colored area and change the orientation, or to use both sides and change the direction of the work.

[0098] Next, based on Figures 5-7 The third embodiment of the pet absorbent sheet 10Y will be described below. Furthermore, in the following description of the third embodiment, the same reference numerals are used for structures identical to those in the above-described and second embodiments, and descriptions are omitted. Figure 5 This is a top view of the pet absorbent sheet of the third embodiment, viewed from the excretory side. Figure 6 It's a pet absorbent tablet along... Figure 1 A schematic cross-sectional view of the DD line shown. Figure 7 yes Figure 5An enlarged top view of part E. The colored portion 80Y of the absorbent sheet 10Y for pets may have a pet face pattern 86 representing the face of the pet to be used, and an auxiliary pattern 84 representing other aspects of the pet. The pet face pattern 86 may include at least a pattern representing the pet's face, and may also include a pattern representing the pet's body. Thus, the pet face pattern 86 may be the same pattern as the pet pattern 81 that identifies the pet to be used, or it may be a different pattern. The auxiliary pattern 84 is a pattern representing other aspects of the pet, and may be any pattern such as a heart or star.

[0099] The coloring section 80Y may have a first coloring section 80A colored with a first color and a second coloring section 80B colored with a second color different from the first color. Specifically, the pet face pattern 86 may have a first pet face pattern 86A colored with a first color and a second pet face pattern 86B colored with a second color. Additionally, the auxiliary pattern 84 may have a first auxiliary pattern 84A colored with a first color and a second auxiliary pattern 84B colored with a second color. The first coloring section 80A has a first pet face pattern 86A and a first auxiliary pattern 84A. The second coloring section 80B has a second pet face pattern 86B and a second auxiliary pattern 84B. That is, the first pet face pattern 86A and the first auxiliary pattern 84A are colored with the same color. Similarly, the second pet face pattern 86B and the second auxiliary pattern 84B are colored with the same color. Furthermore, the first pet face pattern 86A and the first auxiliary pattern 84A mainly utilize the first color for coloring, but can also use colors other than the first color for partial coloring. Similarly, the second pet face pattern 86B and the second auxiliary pattern 84B mainly utilize the second color for coloring, but can also use colors other than the second color for partial coloring. The state of using the main color for coloring refers to the state where the main color is used to color more than 90% of the pattern.

[0100] By featuring a first pet face pattern 86A and a second pet face pattern 86B, the decorative appeal is enhanced, attracting the user's attention. Furthermore, the first pet face pattern 86A and the second pet face pattern 86B are different colors, preventing them from being perceived as a single entity and allowing each to stand out individually. Users can easily identify the pet being used by visually recognizing the pet face pattern. Additionally, the pet face pattern can also represent the face of a cat, allowing users to easily identify the cat as the subject of their use by visually recognizing the pet face pattern.

[0101] The coloring section 80Y may not have non-object patterns representing pets other than the target pet. For absorbent sheets for cats, pets other than the target pet refer to animals such as dogs, rabbits, and hamsters, which are pets other than cats. The pattern representing a pet includes not only the pet's face but also patterns representing parts of the pet's body and its favorite food. Because it does not have non-object patterns, it can be used without confusion even when there are multiple target pets.

[0102] Pet face patterns can represent the entire body of the pet, including its face. By using a pet face pattern to represent the entire body, users can more easily identify their pet. Users can easily identify their pet by visually recognizing the pet pattern.

[0103] The number of pet face patterns 86 can be more than 50% of the total number of patterns. Among all patterns, pet face patterns 86 are more easily visible, allowing users to easily identify their pets by visually recognizing them. Furthermore, the number of pet face patterns 86 can be more than the number of auxiliary patterns 84. Pet face patterns 86 are more easily visible than auxiliary patterns 84, allowing users to easily identify their pets by visually recognizing them.

[0104] The maximum size of the pet face pattern 86 can be larger than the maximum size of the auxiliary pattern 84. More appropriately, the maximum size in the first direction D1 can be larger than the maximum size in the first direction D1 of the auxiliary pattern 84. Furthermore, the maximum size in the second direction D2 of the pet face pattern 86 can be larger than the maximum size in the second direction D2 of the auxiliary pattern 84. The pet face pattern 86 is more conspicuous than the auxiliary pattern 84, allowing the user to easily identify the pet being used by visually recognizing the pet face pattern 86. Users can easily identify the cat as the pet being used by the pet using the pet face pattern 86, preventing the mistake of using the wrong pet even when there are multiple pets being used.

[0105] The first and second colors can be different colors; there are no particular restrictions. The degree of difference between the first and second colors can be more than two shades different from each other in a 24-color chart based on the Oswald color wheel. Alternatively, the first color can be a green-based color, and the second color can be a purple-based color. That is, the first pet face pattern 86A and the first auxiliary pattern 84A constituting the first coloring part 80A can be colored using the first green-based color, and the second pet face pattern 86B and the second auxiliary pattern 84B constituting the second coloring part 80B can be colored using the second purple-based color. Generally, the urine of a healthy pet is yellow-based, while the urine of an unhealthy pet is red-based. The green-based first coloring part 80A and the purple-based second coloring part 80B are easier to distinguish and identify than yellow-based and red-based colors. Therefore, users can easily distinguish and identify the coloring part 80Y from urine, preventing the possibility of mistakenly identifying the coloring part 80Y as urine traces. Therefore, users are less likely to mistake a pet absorbent tablet before use for one after use.

[0106] Furthermore, users can easily distinguish and identify urine and the stained area 80Y, thus focusing their attention on the stained area 80Y. The stained area 80Y can be used to enhance the design of absorbent pads for pets. In addition, by making the stained area 80Y conspicuous, urine becomes relatively inconspicuous, concealing urine traces and improving urine concealment.

[0107] A background portion 88 may be provided around the colored portion in the area overlapping with the absorber, and can be visually identified from the surface side of the surface sheet. The background portion 88 is the portion where the colored portion 80Y is not provided. In this embodiment, the background portion is formed by the surface of the absorber and is white. The color of the pet face pattern may be different from the color of the background portion. The degree of color difference is that it is offset by more than two colors in a 24-color chart classified according to the Oswald color wheel. The color of the background portion is different from both the first color and the second color of the pet face pattern. The pet face pattern is more conspicuous than the background portion, making it easier for the user to identify the pet pattern. The user can easily grasp the pet being used by visually identifying the pet face pattern.

[0108] The coloring section 80Y can be arranged along the designed outline, and a background section 88 is provided in the area surrounded by the coloring section 80Y. Specifically, the pet face pattern 86 is arranged along the outline of a cat, and the auxiliary pattern 84 is arranged along the outline of a butterfly. The background section 88 is provided in the area surrounded by the coloring section 80Y that constitutes this outline. When urine is urinated in the background section 88, the urine and the coloring section 80Y can be compared. In addition, since the coloring section 80Y is arranged around the background section 88, the spread of urine can be monitored using the coloring section 80Y. Thus, the health status of the pet can also be monitored by monitoring the amount of urine.

[0109] like Figure 7 As shown, a second auxiliary pattern 84B can be placed in or near the area overlapping with the first pet face pattern 86A, and a first auxiliary pattern 84A can be placed in or near the area overlapping with the second pet face pattern 86B. Here, "placed near" means that the distance between the two patterns is 10mm or less. With the first pet face pattern 86A and the second auxiliary pattern 84B placed close together, and the second pet face pattern 86B placed close to the first auxiliary pattern 84A, it is possible to compare the first coloring portion 80A and the second coloring portion 80B with urine. This makes it easy to determine whether the pet is healthy or unhealthy. Furthermore, the user can visually identify the first pet face pattern 86A and the second pet face pattern 86B to identify the pet being used. Therefore, even when multiple pets are present, it is easy to identify the pet being used.

[0110] Furthermore, the pet face pattern 86 and the auxiliary pattern 84 are integrated, thus improving the design and enhancing the concealment of urine. Appropriately, the distance L23 between the first assembly (combining the first pet face pattern 86A and the second auxiliary pattern 84B) and the second assembly (combining the second pet face pattern 86B and the first auxiliary pattern 84A) can be longer than the distance L21 between the first pet face pattern 86A and the second auxiliary pattern 84B, and longer than the distance L22 between the second pet face pattern 86B and the first auxiliary pattern 84A. The first assembly (combining the first pet face pattern 86A and the second auxiliary pattern 84B) and the second assembly (combining the second pet face pattern 86B and the first auxiliary pattern 84A) are easily identifiable, and the pet face pattern 86 and the auxiliary pattern 84 are integrated.

[0111] The color of auxiliary pattern 84 differs from the color of the pet face pattern 86, which is positioned closest to it, to a degree that they can be offset by more than two colors in a 24-color chart classified according to the Oswald color wheel. Figure 7 In this design, the pet face pattern 86 positioned closest to the second auxiliary pattern 84B is the first pet face pattern 86A, and the pet face pattern positioned closest to the first auxiliary pattern 84A is the second pet face pattern 86B. Users can easily distinguish and identify the pet pattern and the auxiliary patterns. Users can easily understand and manage the pet they are using by visually recognizing the pet face pattern.

[0112] The maximum size of the first pet face pattern 86A can be larger than the maximum size of the second auxiliary pattern 84B, and the maximum size of the second pet face pattern 86B can be larger than the maximum size of the first auxiliary pattern 84A. The first pet face pattern 86A and the second pet face pattern 86B are easy to spot, allowing the user to easily identify the pet being used.

[0113] The outer coloring section 87 can be a similar color to the first color. The degree of similarity is within the range of the same color card or a hue number differing by only one in the 24 colors classified according to the Oswald color wheel. This allows the outer coloring section to be integrated with the first color pattern, enhancing its decorative appeal and attracting the user's attention. Furthermore, by integrating the outer coloring section with the first color pattern, the second color pattern becomes relatively more prominent. Users can easily identify their pet by recognizing either the first or second color pattern.

[0114] Next, based on Figure 8 The fourth embodiment of the pet absorbent sheet 10Z is described. Figure 8 This is a top view of the pet absorbent sheet according to the fourth embodiment, viewed from the excretory side. Furthermore, in the description of the fourth embodiment, the same reference numerals are used for structures identical to those in the above embodiments, and descriptions are omitted.

[0115] The coloring section 80Z in the fourth embodiment has a pet face pattern 861 and a non-object pattern 83, but no auxiliary patterns. The non-object pattern 83 is a pattern representing a dog, which is a pet other than the intended user. Specifically, the non-object pattern includes a pattern representing the dog as a whole and a pattern representing a bone that the dog likes. The number of pet face patterns 861 can be more than twice the number of non-object patterns 83. The user can easily identify the intended pet by visually recognizing the pet face pattern. Since the number of pet face patterns is more than twice the number of non-object patterns, the user can easily identify that the pet face pattern is the intended pet, thus preventing the misuse of the intended pet. Even when there are multiple intended pets, the user can use the device without making a mistake.

[0116] The maximum size of the pet face pattern 86 can be larger than the maximum size of the non-object pattern 83. The pet face pattern 86 is more eye-catching than the non-object pattern 83, and users can easily identify the pet being used by visually recognizing the pet face pattern 86.

[0117] The color of the non-object pattern 83 differs from the color of the pet face pattern 86, which is positioned closest to it, by a degree that they are at least two colors apart in a 24-color chart based on the Oswald color wheel. Users can easily distinguish and identify the pet face pattern 86 and the non-object pattern 83. By visually recognizing the pet face pattern 86, users can easily identify the pet being used.

[0118] Pet face pattern 861 has a first pet face pattern 861A colored with a first color and a second pet face pattern 861B colored with a second color. The first pet face pattern 861A and the second pet face pattern 861B are not only outlines but also fill patterns. Pet face patterns are more eye-catching.
