JP-A-2017-131160

The pet diaper of Patent Document 1 is configured so that it can be worn on dogs and also on cats. However, as a result of diligent research by the applicant, it was found that the shape of the leg circumference in cats and the shape of the leg circumference in dogs are significantly different. More specifically, there is relatively little flesh around the bones near the base of the dog's leg. Also, the dog's legs on all fours are relatively straight, although they are slightly bent at the joints. On the other hand, in the vicinity of the base of the leg of a cat, the flesh around the bone is more than that of a dog. In addition, the legs of the cat on all fours are greatly bent at the joints. In this way, cats have a lot of flesh at the base of their legs, and the joints at the base are bent, so it may be difficult to fit the diaper to the base of the leg compared to dogs. If the diaper did not fit to the base of the leg, it could slip or come off during the wearing process.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a cat diaper that can be easily fitted to a cat's leg circumference.

(1) Outline of Embodiment At least the following matters will be clarified by the description of this specification and the accompanying drawings.
The cat diaper according to one embodiment has a lateral direction arranged along the waist circumference of the cat, a vertical direction orthogonal to the lateral direction and extending from the ventral side to the dorsal side of the pet, and an absorption core. Then, the main body portion straddling the ventral region, the inseam region, and the dorsal region, the leg circumference opening arranged around the cat's leg, and the laterally extending laterally from the main body portion, the belly It has a fastening tape that joins the side region and the dorsal region. The leg circumference openings are a ventral side extending inward in the lateral direction from the outer edge of the main body on the ventral side, and a dorsal side extending inward in the lateral direction from the outer edge of the main body on the dorsal side. It has a side, a vertical side that connects the ventral side and the dorsal side, and extends in the vertical direction. Assuming that the length of the ventral side in the vertical direction is a and the length of the ventral side in the lateral direction is b, a <b is satisfied. The leg opening is arranged so as to surround the cat's hind legs, and the ventral side of the leg opening corresponds to the ventral surface of the cat's hind legs. Since the lateral length b of the ventral side is longer than the vertical length a of the ventral side, the vertical length is within a short range when the leg circumference opening is fitted to the leg circumference. Can secure an area extending in the lateral direction. Since it enters locally in the horizontal direction within a short range in the vertical direction, it is easy to fit tightly to the leg circumference. By fitting tightly around the legs, it is easy to fit tightly around the legs without being aware of it for cats that have a relatively large amount of flesh or bent joints and are difficult to fit tightly around the legs. , It is possible to suppress the problem of coming off during the wearing process.

The cat diaper according to the other aspect has a lateral direction arranged along the waist circumference of the cat, a vertical direction orthogonal to the lateral direction and extending from the ventral side to the dorsal side of the pet, and an absorption core. Then, the main body portion straddling the ventral region, the inseam region, and the dorsal region, the leg circumference opening arranged around the cat's leg, and the laterally extending laterally from the main body portion, the belly It has a fastening tape that joins the side region and the dorsal region. The leg circumference openings are a ventral side extending inward in the lateral direction from the outer edge of the main body on the ventral side, and a dorsal side extending inward in the lateral direction from the outer edge of the main body on the dorsal side. It has a side, a vertical side that connects the ventral side and the dorsal side, and extends in the vertical direction. Assuming that the distance between the fastening tape and the vertical side in the vertical direction is c and the length of the ventral side in the horizontal direction is b, c <b is satisfied. When attaching a diaper to a cat, pull the fastening tape laterally to join it to the target portion or the like. At this time, the ventral side of the leg circumference opening is pulled laterally, and the line extending from between both hind legs to the dorsal side through the hind legs is composed of a line connecting the vertical side and the fastening tape. .. Since the distance c is shorter than the lateral length b of the ventral side, when the leg circumference opening fits the leg circumference, a region extending in the lateral direction is secured within a short range of the vertical length. can. Since it enters locally in the horizontal direction within a short range in the vertical direction, it is easy to fit tightly to the leg circumference. By fitting it tightly around the legs, it is possible to prevent problems that come off during the wearing process.

According to a preferred embodiment, where d is the length of the main body in the vertical direction, the ratio of a to d may be 10% or less. According to this aspect, since the ratio of the vertical length a of the ventral side to the entire main body of the diaper is low, the vertical deviation with respect to the leg circumference can be suppressed. It is possible to suppress problems such as the diaper coming off when worn or hindering the front-back movement of the legs due to the large amount of displacement in the vertical direction.

According to a preferred embodiment, the fastening tape is arranged in the ventral region, and the dorsal region is provided with at least a part of a target portion to which the fastening tape is fastened, and the ventral region is provided. Assuming that the vertical distance between the side and the target portion is e and the vertical length of the main body portion is d, the ratio of e to d may be 60% or more. The vertical distance e between the ventral side and the target portion covers the body from the ventral side to the dorsal side with the fastening tape fixed to the target portion, and follows the movement of the body and the expansion and contraction of the skin. It is the length of the region that deforms. Since the ratio of the length of the vertical distance e between the ventral side and the target portion to the entire main body of the diaper is high, a wide area that deforms according to the movement of the cat can be secured.

According to a preferred embodiment, the body portion is provided with a tail hole having a hole body portion through which the cat's tail can be inserted, and the fastening tape is arranged in the ventral region and the dorsal region. Is provided with at least a part of a target portion to which the fastening tape is fastened, and the distance between the dorsal edge of the tail hole and the target portion in the vertical direction is f, and the main body portion. The ratio of f to d may be 20% or more, where d is the length in the vertical direction. Here, the distance f is the distance between the target portion and the combined region of the cut portion and the hole main body portion in the configuration having the cut portion. The vertical distance f between the dorsal edge of the tail hole and the target portion is the length of the region covering the region from the tail hole to the dorsal side with the fastening tape fixed to the target portion, and is the dorsal side. It is the length of the region that deforms following the movement of the body and the expansion and contraction of the skin. Since the ratio of the length of f to the entire main body is high, a wide area that deforms according to the movement of the cat can be secured on the dorsal side, and the diaper follows the movement of the dorsal side, causing the diaper to shift unintentionally. Can be suppressed.

According to a preferred embodiment, the body portion is provided with a tail hole having a hole body portion through which the cat's tail can be inserted, and the fastening tape is arranged in the ventral region and the dorsal region. Is provided with at least a part of a target portion to which the fastening tape is fastened, and the vertical distance between the ventral side and the target portion is defined as e, and the hole main body portion is provided in the vertical direction. Assuming that the maximum length is g, the ratio of g to e may be 3.50% or less. As a result of diligent research by the applicant, dogs often move their tails relatively horizontally, and cats often move their tails vertically in comparison. Therefore, when the cat wears the diaper, the hole main body is pulled in the vertical direction, and the diaper tends to shift in the vertical direction. At this time, since the ratio of the length of the hole main body in the vertical direction to the range of motion is low, the amount of the diaper shifting in the vertical direction through the hole main body can be suppressed.

According to a preferred embodiment, the body portion is formed with a tail hole having a hole body portion through which the cat's tail can be inserted and a notch portion for enlarging the size of the tail hole. The tape is arranged in the ventral region, and a target portion to which the fastening tape is fastened is provided in the dorsal region, and the distance between the ventral side and the target portion in the vertical direction is e. Assuming that the maximum length of the tail hole in the vertical direction is h, the ratio of h to e may be 5.5% or less. According to this aspect, even when the size of the tail hole is increased by the notch, the ratio of the length of the tail hole to the range of motion in the vertical direction is lowered, and the amount of the diaper being displaced in the vertical direction through the tail hole is reduced. Can be suppressed.

According to a preferred embodiment, the body portion is provided with a tail hole having a hole body portion through which the cat's tail can be inserted, and the hole body portion is provided in the lateral direction with respect to the maximum lateral length of the absorption core. The ratio of the maximum length of is 35% or more. By inserting the tail into the tail hole at the time of wearing, the tail hole can be pulled laterally through the tail, and the absorption core can be pulled laterally. The twist of the absorption core can be widened, and it is easy to secure the lateral length of the absorption core when worn. Since the ratio of the maximum lateral length of the hole body to the maximum lateral length of the absorption core is high, the force for expanding the absorption core through the hole body is easily transmitted over the entire lateral direction of the absorption core. The fit is unlikely to deteriorate due to the deformation of the absorption core, the leakage of body fluid can be suppressed, and the state in which the cat can easily move its legs when worn can be maintained.

According to a preferred embodiment, the tail hole may be located dorsally of the dorsal outer edge of the absorption core. Since the tail hole is provided in a region that does not overlap with the absorption core, the force that pulls the tail hole laterally through the tail is not easily affected by the rigidity of the absorption core. Therefore, it is easier to obtain the effect of reducing the twist of the absorption core via the tail.

According to a preferred embodiment, the absorption core has an inwardly recessed constriction in the lateral direction, at least one of the ventral edges extending from the lateral medial edge of the constriction toward the ventral side. The portion extends from the ventral side toward the medial edge in the lateral direction, and the vertical side of the leg circumference opening extends from the ventral side toward the dorsal side in the lateral direction. May extend to. By shortening the lateral length of the absorbent core at the inner edge of the constricted portion, it is easy to fit the absorbent core to the portion where the lateral length of both legs of the cat is short. In addition, since the lateral length increases from the medial edge of the constriction toward the ventral side, the lateral length of the absorption core at the medial edge of the constriction is shortened, while the absorption core on the ventral side is shortened. Area can be secured. Further, the vertical side of the leg circumference opening extends inward in the lateral direction from the dorsal side to the ventral side, and has an inclination opposite to the outer edge of the absorption core. Therefore, in the portion where the lateral length of the absorption core is shortened, the lateral length of the leg circumference opening can be provided to be long, and the diaper as a whole can continue to cover the waist circumference and prevent leakage and slippage.

When the cat diaper 1 is attached to the cat, the third end 63 of the main body (the end on the side where the joint 92 is provided) is applied to the belly of the cat. At this time, the fourth end 64 of the main body is passed between both legs of the cat and is put out to the rear side of the cat. Then, while the center of the main body 2 in the vertical direction Z is applied to the urination port of the cat, the tail of the cat is put out to T2 on the back surface side of the diaper through the tail hole 70. The fourth end 64 of the main body covers the buttocks and back of the cat. Next, the joint portion 92 is pulled toward the back side of the cat, and the joint portion 92 is fixed to the target portion 45 of the fourth end portion 64 of the main body located on the back side on the outer surface. As a result, as shown in FIG. 3, the cat diaper 1 can be worn so as to cover the cat's belly, back, and inseam. That is, the cat diaper 1 is worn so as to cover from the ventral side of the cat through the inseam to the dorsal side.

The diaper of the present embodiment is configured to easily fit around the legs of a cat. Next, the configuration for facilitating the fit to the leg circumference of the cat will be described in detail. FIG. 4 is a diagram schematically showing the shapes of the bodies of cats and dogs. FIG. 4A shows the shape of the cat's body, and FIG. 4B shows the shape of the dog's body. As shown in FIG. 1, the leg circumference opening 5 has a ventral side 51 extending inward in the lateral direction W from the outer edge 2E of the main body 2 on the ventral side, and laterally from the outer edge 2E of the main body 2 on the dorsal side. It may have a dorsal side 52 extending inward in the direction W, and a vertical side 53 connecting the ventral side 51 and the dorsal side 52 and extending in the vertical direction Z. When the vertical side 53 is straight and the ventral side 51 and the dorsal side 52 are curved, the boundary between the ventral side 51 and the vertical side 53 is the boundary between the straight line and the curved line. You can. Further, when the ventral side 51, the dorsal side 52, and the vertical side 53 all have a curved shape, a portion where the curvature changes may be used as a boundary. Further, in a form in which there are a plurality of boundaries in which the curvature changes, the portion extending at an angle of 45 or less with respect to the lateral direction W is set as the ventral side 51 and the dorsal side 52, and is less than 45 with respect to the vertical direction Z. The boundary may be set with the portion extending at the angle of 1 as the vertical side 53. When the leg circumference opening has an arc shape with a constant radius of curvature, the intersection of the virtual line extending laterally and the leg circumference opening 5 passing through the center of the arc radius of curvature is the ventral side 51 and the vertical side. It may be the boundary of the side 53 or the boundary between the dorsal side 52 and the vertical side 53. When the leg circumference opening 5 has an elliptical arc shape in which the radius of curvature changes, the intersection of the virtual line extending laterally and the leg circumference opening 5 passing through the center of each radius of curvature is the ventral side 51. And the boundary between the vertical side 53 or the boundary between the dorsal side 52 and the vertical side 53.

As shown in FIG. 1, if the length of the ventral side 51 in the vertical direction Z is a and the length of the ventral side 51 in the lateral direction W is b, a <b may be satisfied. In other words, the length a of the ventral side 51 in the vertical direction Z is the distance between the ventral edge of the leg circumference opening 5 and the vertical side 53 in the vertical direction Z. The length b of the ventral side 51 in the lateral direction W is, in other words, the distance between the first edge 61E and the ventral edge of the vertical side 53 in the lateral direction W. When wearing a diaper on a cat, the fastening tape 90 is in a state where the ventral region S1 is applied to the ventral side of the cat, the inseam region S3 is applied to the inseam of the cat, and the dorsal region S2 is applied to the back side of the cat. The ventral region S1 and the dorsal region S2 are anchored by. As shown in FIG. 3, in the worn state, the leg circumference opening 5 is arranged so as to surround the hind legs of the cat, and the ventral side 51 of the leg circumference opening 5 corresponds to the ventral surface of the hind legs of the cat. .. Since the length b in the lateral direction W of the ventral side 51 is longer than the length a in the vertical direction Z of the ventral side 51, when the leg circumference opening 5 fits against the leg circumference, the vertical direction Z A region extending in the lateral direction W can be secured within a short range. For example, in the case of a = b, since the length of the ventral side 51 in the vertical direction Z and the length of the horizontal direction W are the same, the legs gradually enter the horizontal direction within the long range of the vertical direction Z. Easy to fit loosely around.

As shown in FIG. 4, as a result of diligent investigation by the applicant, it was found that the shape of the leg circumference in the cat and the shape of the leg circumference in the dog are significantly different. More specifically, there is relatively little flesh around the bones near the base of the dog's leg. Also, the dog's legs on all fours are relatively straight, although they are slightly bent at the joints. On the other hand, in the vicinity of the base of the leg of a cat, the flesh around the bone is more than that of a dog. In addition, the legs of the cat on all fours are greatly bent at the joints. In this way, cats have a lot of flesh at the base of their legs, and the joints at the base are bent, so it may be difficult to fit the diaper to the base of the leg compared to dogs. If the diaper did not fit to the base of the leg, it could slip or come off during the wearing process. However, by satisfying a <b, since it locally enters the inside of the horizontal direction W within a short range in the vertical direction Z, it is easy to fit tightly to the leg circumference. By fitting tightly around the legs, it is difficult for cats that have a relatively large amount of flesh or bent joints to fit tightly around the legs. It is easy to fit and can prevent problems that come off during the wearing process.

Assuming that the distance between the fastening tape 90 and the vertical side 53 in the vertical direction Z is c and the length of the ventral side 51 in the horizontal direction W is b, c <b may be satisfied. In other words, the distance c in the vertical direction Z between the fastening tape 90 and the vertical side 53 is the distance Z in the vertical direction between the boundary between the ventral side 51 and the vertical side 53 and the dorsal edge of the fastening tape 90. Is. When the diaper is attached to the cat, the fastening tape 90 is pulled laterally to be joined to the target portion 45 or the like. At this time, the ventral side 51 side of the leg circumference opening 5 is pulled in the lateral direction W, and the line extending from between both rear legs to the dorsal side through the rear legs connects the vertical side 53 and the fastening tape 90. It is composed of lines extending in the vertical direction Z. Since the distance c is shorter than the length b of the lateral direction W of the ventral side 51, when the leg circumference opening 5 fits the leg circumference, the lateral direction W is within a range in which the length of the vertical direction Z is short. It is possible to secure an area extending to. Since it locally enters in the horizontal direction within a short range in the vertical direction Z, it is easy to fit tightly to the leg circumference. By fitting it tightly around the legs, it is possible to prevent problems that come off during the wearing process.

Assuming that the length Z of the main body 2 in the vertical direction is d, the ratio of the length a of the ventral side 51 in the vertical direction Z to d may be 10% or less. In other words, the length d of the main body 2 in the vertical direction Z is the distance between the third edge 63E and the fourth edge 64E in the vertical direction Z. The length of the main body 2 in the vertical direction Z may be the total length of the cat diaper 1 in the vertical direction Z. Since the ratio of the length a of the ventral side 51 to the entire main body 2 in the vertical direction is low, the deviation of the vertical direction Z with respect to the leg circumference can be suppressed. It is possible to suppress problems such as the diaper coming off when worn or hindering the front-back movement of the legs due to the large amount of displacement in the vertical direction Z.

Assuming that the vertical distance between the ventral side 51 and the target portion 45 is e, the ratio of e to the length d in the vertical direction Z of the main body portion 2 may be 60% or more. The vertical distance between the ventral side 51 and the target portion 45 is, in other words, the vertical distance between the boundary between the ventral side 51 and the vertical side 53 and the target portion 45. The region between the ventral side 51 and the target portion 45 in the vertical direction Z covers the body from the ventral side to the dorsal side with the fastening tape 90 fixed to the target portion 45 or the like, and the movement of the body and the skin. It is a region that deforms following the expansion and contraction of. Since the ratio of the length of e to the entire main body 2 is high, a wide area that deforms according to the movement of the cat can be secured. In addition, as a result of diligent investigation by the applicant, it was found that the way of normal physical movement differs greatly between cats and dogs. More specifically, it was found that dogs have more movements in the plane direction such as running on the ground, and cats have more movements in the vertical direction such as jumping and jumping than dogs. When trying to move the body in the vertical direction, the abdomen, buttocks and undercarriage may be extended from the bent hind legs at a stretch, or from the bent and extended legs and the dented abdomen and the rounded back. The amount of expansion and contraction of the skin tends to increase. By ensuring the length of e, the diaper can be made to follow when the body is moved in the vertical direction, and the diaper can be prevented from being unintentionally displaced.

Assuming that the distance between the dorsal edge of the tail hole 70 and the target portion 45 in the vertical direction Z is f, the ratio of f to the length d in the vertical direction Z of the main body portion 2 may be 20% or more. The distance f between the dorsal edge of the tail hole 70 and the vertical direction Z of the target portion 45 is the length of the region covering the region extending from the tail hole 70 to the dorsal side with the fastening tape 90 anchored to the target portion 45. It is the length of the region that deforms following the movement of the body on the dorsal side and the expansion and contraction of the skin. Compared to dogs, cats often take a posture of curling up and stretching, sitting with their backs curled up, and curling their backs. If you take a posture with your back curled up or with your back extended, the movement of your back and the amount of expansion and contraction of your skin will be large. Since the ratio of the length of f to the entire main body 2 is high, a wide area that deforms according to the movement of the cat can be secured on the dorsal side, the diaper is made to follow the movement of the dorsal side, and the diaper shifts unintentionally. Can be suppressed. Further, preferably, the distance f between the tail hole (hole main body portion 71 + cut portion 72) 70 and the target portion 45 in the vertical direction Z may be 20% or more with respect to the length d in the vertical direction Z of the main body portion 2. .. The distance f between the tail hole (hole body 71 + notch 72) 70 and the target portion 45 in the vertical direction Z is for the movement of the body on the dorsal side and the expansion and contraction of the skin in a state where the opening of the tail hole is enlarged by the notch 72. It is the length of the region that follows and deforms. According to this configuration, even when the size of the tail hole 70 is increased by the notch 72, a wide area that deforms according to the movement of the cat can be secured on the dorsal side, and the diaper follows the movement on the dorsal side. It is possible to prevent the diaper from slipping unintentionally.

Assuming that the maximum length of the hole main body portion 71 in the vertical direction Z is g, the ratio of g to the distance e of the ventral side 51 and the target portion 45 in the vertical direction Z may be 3.50% or less. Dogs often move their tails relatively left and right, and cats often move their tails up and down in comparison. Therefore, when the cat wears the diaper, the hole main body 71 is pulled in the vertical direction, and the diaper tends to shift in the vertical direction Z. At this time, since the ratio of the length of the hole main body 71 in the vertical direction to the range of motion is low, the amount of the diaper shifting in the vertical direction Z via the hole main body 71 can be suppressed. Further, assuming that the maximum length of the tail hole in the vertical direction is h, the ratio of h to the distance e of the ventral side 51 and the target portion 45 in the vertical direction Z may be 5.5% or less. The maximum length h of the tail hole 70 in the vertical direction Z is the maximum length h of the tail hole (hole body portion 71 + cut portion 72) 70 in the vertical direction Z. According to this configuration, when the size of the tail hole 70 is increased by the notch 72, the ratio of the length of the tail hole 70 to the range of motion in the vertical direction is lowered, and the diaper is formed in the vertical direction Z through the tail hole 70. The amount of deviation can be suppressed.

The ratio of the maximum length of the horizontal direction W of the hole main body 71 to the maximum length of the horizontal direction W of the absorption core 30 may be 35% or more. By inserting the tail into the tail hole 70 at the time of wearing, the hole body 71 of the tail hole 70 can be pulled laterally W through the tail, and the absorption core 30 has a force extending in the lateral direction W. It takes. It is possible to reduce the twist of the absorption core 30 by expanding it in the lateral direction W of the absorption core 30, and it is easy to secure the length of the absorption core 30 in the lateral direction W when worn. In particular, cats have a higher ratio of tail diameter to waist circumference than dogs. Therefore, it is easy to obtain the effect of reducing the twist of the absorption core 30 via the tail. The twist of the absorption core 30 can be widened, and it is easy to secure the length of the absorption core 30 in the lateral direction W when worn. Further, since the ratio of the maximum length of the hole main body 71 to the maximum length of the horizontal W of the absorption core 30 is high, the force to spread the absorption core 30 through the hole main body 71 is the force of the absorption core 30. It is easy to transmit to the entire lateral direction W. The fit is unlikely to deteriorate due to the deformation of the absorption core 30, the leakage of body fluid can be suppressed, and the state in which the cat can easily move its legs when worn can be maintained. Further, preferably, the ratio of the tail hole (hole body portion 71 + cut portion 72) 70 to the maximum length of the lateral W of the absorption core 30 to the maximum length of the lateral W of the absorption core 30 may be more than 40%. According to this configuration, when the size of the tail hole 70 is increased by the notch 72, the ratio of the maximum lateral length of the hole main body 71 to the maximum lateral length of the absorption core 30 is high, so that the tail is tailed. The force that spreads the absorption core 30 through the hole 70 is easily transmitted over the entire lateral direction W of the absorption core 30. Further, the tail hole 70 may be arranged on the dorsal side of the dorsal outer edge R30 located on the dorsal side of the absorption core 30. Since the tail hole 70 is provided in a region that does not overlap with the absorption core 30, the force that pulls the tail hole 70 laterally through the tail is not easily affected by the rigidity of the absorption core 30. Therefore, it is easier to obtain the effect of reducing the twist of the absorption core 30 via the tail.

Next, the absorption core 30 will be described in detail with reference to FIG. FIG. 5 is an enlarged plan view of the absorption core 30. The absorption core 30 may have a constricted portion 31 constricted inside in the lateral direction W. The constricted portion 31 is a portion recessed inward in the lateral direction W from the outer edge 30E of the absorption core 30. The inner edge 31D of the constricted portion 31 is a portion of the constricted portion 31 located on the innermost side in the lateral direction, and the outer edge 31E of the constricted portion 31 is a portion of the constricted portion 31 located on the outermost side of the lateral direction W. , May coincide with the outer edge 30E of the absorption core 30. The ventral edge P311 of the inner edge 31D of the constriction portion 31 in the lateral direction W may be located dorsal to the center CZ30 of the absorption core 30 in the longitudinal direction Z. In the configuration in which the inner edge 31D of the constricted portion 31 does not extend in the vertical direction Z as in the present embodiment, the ventral end edge P311 is a point, and the dorsal edge 31D of the constricted portion 31 at the inner edge 31D. It coincides with the side edge P312. However, in the configuration extending in the vertical direction Z of the inner edge 31D of the constricted portion 31, the ventral end edge P311 is the most ventral edge of the inner edge 31D extending in the vertical direction Z. It is separated from the dorsal edge P312 in the vertical direction Z.

As shown in FIG. 3, in the worn state, the leg circumference opening 5 is arranged so as to surround the hind legs of the cat, and the inner edge 31D of the constricted portion 31 of the absorption core 30 has a leg width (both legs) from the hind legs to the buttocks. It fits around the portion 105 (see FIG. 4) where the distance between the two is the narrowest. At this time, in the conventional diaper for both dog and cat, the ventral end edge P311 in the inner edge 31D of the constricted portion 31 is biased toward the center CZ30 or the ventral side in the vertical direction Z of the absorption core 30. Have been placed. Therefore, it was not possible to secure a sufficient length of the absorption core 30 extending ventral to the ventral side from the position where the leg width is the narrowest in the vertical direction Z. Therefore, when the amount of expansion and contraction of the skin in the abdomen increases with the vertical movement of the cat, the absorption core 30 cannot continue to follow, and there is a problem that the diaper shifts or comes off. In addition, when the cat bends or extends its hind legs in an attempt to move in the vertical direction, the absorption core 30 extending ventral to the position 105 where the leg width is the narrowest is repeatedly deformed, making it difficult to continue covering the body. there were. As a result of the applicant observing the wearing state of the cat, the length of the absorption core 30 extending ventral to the position 105 where the leg width is the narrowest is ventral to the ventral edge P311. It was found that it corresponds to the vertical length of the absorption core 30 extending to. Since the ventral end edge P311 in the inner edge 31D of the lateral direction W of the constricted portion 31 is located on the dorsal side of the center CZ30 of the vertical direction Z of the absorption core, the leg width is smaller than the position 105 where the leg width is the narrowest. A sufficient length of the absorption core 30 extending to the ventral side in the vertical direction Z can be secured. Therefore, the body can be covered by the absorption core 30 even when the legs are repeatedly moved back and forth by the vertical movement. Further, since the length Z in the vertical direction of the absorption core 30 extending ventrally from the position 105 where the leg width is the narrowest can be sufficiently secured, the amount of expansion and contraction of the skin in the abdomen becomes large. Can keep the absorption core following, making it easier to keep the diaper on.

The length Z31D (see FIG. 7) of the inner edge 31D of the constricted portion 31 in the vertical direction Z may be 30% or less of the length Z30 in the vertical direction Z of the absorption core 30. The inner edge 31D of the constricted portion 31 of the present embodiment is point-shaped, and the length of the inner edge 31D in the vertical direction Z is as close to 0 as possible. When the cat moves in the vertical direction, the diaper tends to shift in the vertical direction Z due to the impact such as landing and the vertical expansion and contraction of the skin. At this time, since the length of the inner edge 31D of the constricted portion 31 is 30% or less, the amount of deviation in the vertical direction Z is 30% or less of the absorption core in a state of being fitted to the position 105 where the leg width is the narrowest. Become. Even when a force acts in the direction in which the diaper shifts due to an impact or the like, the diaper can be covered against the body. Further, the length Z31D of the inner edge 31D in the vertical direction Z may be 40% or less of the length Z31 of the constricted portion 31 in the vertical direction Z. Since the ratio of the length of the vertical direction Z occupied by the inner edge 31D in the constricted portion 31 is low, the amount of displacement of the diaper in the vertical direction Z can be suppressed.

The constricted portion 31 has a ventral base end edge 311 located on the ventral side, a dorsal base end edge 312 located on the dorsal side, and a side edge 33 connecting the inner edge 31D. The abdominal base end edge 311 is the most ventral edge of the constriction 31, and the dorsal base end edge 312 is the most dorsal edge of the constriction 31. The side edge 33 has a ventral edge F33 extending from the ventral base edge 311 to the medial edge 31D and a dorsal edge R33 extending from the dorsal base edge 312 to the medial edge 31D. The ventral edge F33 and the dorsal edge R33 may be asymmetric rather than symmetrical with respect to the lateral virtual line extending in the lateral direction W. The ventral edge F33 has a portion SF33 extending linearly from the ventral base end edge 311 toward the dorsal side, and a portion CF33 connecting the linearly extending portion SF33 and the inner edge 31D in a curved line. The linearly extending portion SF33 is inclined at an angle α with respect to the vertical direction Z. The angle α is smaller than the inclination angle of the curvedly connected portion CF33 with respect to the vertical direction Z. Further, in the ventral edge F33, the length of the portion SF33 extending linearly in the vertical direction Z is shorter than the length of the portion CF33 connected in a curved shape in the vertical direction Z. Therefore, the ventral edge F33 has a shape in which the constricted portion 31 is gently recessed in the lateral direction W in a region equal to or more than half of the vertical direction Z, and is locally recessed in the lateral direction W in a short range of the constricted portion 31 in the vertical direction Z. Is. Therefore, the deviation of the vertical Z in the leg circumference of the cat can be further suppressed. Further, the dorsal edge R33 extends in a curved line from the dorsal base end edge 312 toward the inner edge 31D, and does not have a portion extending in a straight line.

The first intersection P1 where the virtual line WL31 which passes through the center of the constriction portion 31 in the lateral direction and extends in the vertical direction intersects the ventral edge F33, and the second intersection where the virtual line WL31 intersects the dorsal edge R33. The distance G12 from P2 may be less than 40% of the length Z30 of the absorption core 30 in the longitudinal direction Z. The distance G12 between the first intersection P1 and the second intersection P2 is the length of the constricted portion 31 in the vertical direction Z at the center of the lateral direction W of the constricted portion 31, and the absorption core 30 does not come into close contact with the hind legs in the vertical direction. The length is within the range in which the absorption core easily shifts to Z. Since the distance G12 between the first intersection P1 and the second intersection P2 is less than 40% of the length Z30 of the absorption core 30 in the vertical direction Z, the amount of deviation of the vertical Z around the hind legs is 40 of the absorption core 30. Easy to keep below%. Even when a force that causes the diaper to shift in the vertical direction Z is applied due to an impact or the like, the diaper can be covered against the body.

At least a part of the ventral edge F33 extending ventrally in the constricted portion 31 of the absorption core 30 may extend laterally outward from the medial edge 31D toward the ventral side. More specifically, of the ventral edge F33, the portion SF33 extending linearly from the ventral base end edge 311 to the dorsal side and the portion CF33 extending linearly from the medial edge 31D to the ventral side are laterally W, respectively. It extends outward. The length of the absorption core 30 in the lateral direction W is shortened at the inner edge 31D of the constricted portion 31, so that the absorption core 30 can be easily fitted to the portion where the lateral length of both legs of the cat is short. In particular, the cat has a narrower leg width than the dog and the length of the lateral W of the absorption core 30 is shorter, so that the cat can be fitted more favorably to the body shape of the cat. Further, since the length of the lateral direction W increases from the inner edge 31D of the constricted portion 31 toward the ventral side, the length of the lateral W of the absorption core 30 at the inner edge 31D of the constricted portion 31 is shortened. Also, the area of the absorption core 30 on the ventral side can be secured. Further, the vertical side 53 of the leg circumference opening 5 may extend outward in the lateral direction W from the ventral side to the dorsal side. The portion extending outward in the lateral direction W from the ventral side to the dorsal side straddles the region on the ventral side of the medial edge 31D and the region on the dorsal side of the medial edge. The vertical side 53 of the leg circumference opening 5 extends inward in the lateral direction W from the dorsal side to the ventral side, and has an inclination opposite to the outer edge of the absorption core 30. Therefore, in the portion where the length of the lateral W of the absorption core 30 is shortened, the length of the lateral W of the leg circumference opening 5 can be increased, and the diaper as a whole continues to cover the waist circumference to suppress leakage and slippage. can.

The absorption core 30 has a ventral outer edge F30 located on the ventral side and a dorsal outer edge R30 located on the dorsal side. The ventral outer edge F30 is the most ventral edge of the absorption core 30, and the dorsolateral edge R30 is the most ventral edge of the absorption core 30. The distance GF30 between the ventral outer edge F30 and the first intersection P1 may be longer than the distance GR30 between the dorsolateral edge R30 and the second intersection P2. The first intersection P1 and the second intersection P2 are located at the center of the lateral direction W in the constricted portion 31, and easily hit the center of the lateral direction W of the hind legs of the cat. The length of the absorption core 30 extending ventral to the ventral side of the center of the lateral direction W in the constricted portion 31 is the length of the absorption core 30 extending to the dorsal side of the center of the lateral direction W in the constricted portion 31. It is longer than the length in the vertical direction Z. Since the length Z of the absorption core 30 extending ventral to the hind legs can be sufficiently secured, the absorption core 30 can be continuously followed even when the amount of expansion and contraction of the skin in the abdomen becomes large. It is easy to keep the diaper on. Further, in order to secure the length of the absorption core 30 extending ventral to the hind legs in the vertical direction Z, at least a part of the inner edge 31D of the constricted portion 31 is from the center CZ30 of the absorption core 30 in the vertical direction Z. May also be located on the ventral side.

The absorption core 30 includes a ventral region RF30 located ventral to the center CZ30 in the vertical direction Z of the absorption core 30 and a dorsal region RR30 located dorsal to the center CZ30 in the vertical Z of the absorption core 30. Has. The area of the ventral region RF30 may be larger than the area of the dorsal region RR30. The urination port 201F of a female dog easily hits the dorsal region RR30, and the urination port 201M of a male dog easily hits the ventral region RF30. On the other hand, the cat urination port 101 easily hits the dorsal region RR30 in both males and females. In cat diapers, by increasing the area of the ventral region RF30, it is possible to retain the body fluid that diffuses from the dorsal region RR30 to the ventral region RF30. Also, in general, cats drink less water and are more susceptible to urinary diseases. Symptoms of polydipsia and polyuria are more likely to occur when suffering from urinary disorders. In the case of polyuria, the tendency for diffusion to spread to the ventral region RF30 of the absorption core 30 becomes more pronounced. By increasing the area of the ventral region RF30, it is possible to retain the body fluid that diffuses from the dorsal region RR30 to the ventral region RF30 even when polyuria occurs.

The lateral W length WD30 of the absorption core 30 at the inner edge 31D of the constriction 31 may be 80% or less of the maximum lateral length of the absorption core 30 in the dorsal region RR30. The length WD30 of the absorption core 30 in the lateral direction W at the inner edge 31D of the constricted portion 31 is the distance between the left and right inner edges 31D. The maximum lateral length of the absorption core 30 in the dorsal region RR30 is, in the present embodiment, the distance between the outer edges 30E of the absorption core 30. A large difference can be provided between the maximum length of the lateral direction W in the dorsal region RR 30 of the absorption core 30 and the length of the lateral direction W of the absorption core 30 in the inner edge 31D of the constricted portion 31. As described above, the cat urination port 101 easily hits the dorsal region RR30 in both males and females. In cat diapers, the absorption capacity of the dorsal region RR30 can be secured by increasing the maximum length of the lateral W of the absorption core 30 of the dorsal region RR30. In addition, in cats, the distance between the urination port 101 and the tail 102 is shorter than that in dogs, and body fluid easily leaks from the tail hole 70. By increasing the maximum length of the absorption core 30 in the dorsal region RR30 in the lateral direction W, the absorption capacity of the dorsal region RR30 can be secured and the leakage of body fluid from the tail hole 70 can be suppressed. In addition, cats generally have less individual differences in body shape than dogs, and the leg width of the portion 105 having the narrowest leg width is short. By shortening the length WD30 of the absorption core 30 in the lateral direction W at the inner edge 31D of the constricted portion 31, the diaper can be appropriately fitted to the portion 105 having the shortest leg width.

As shown in FIG. 1, the maximum length M70 of the tail hole 70 in the lateral direction W may be equal to or greater than the length WD30 of the absorption core 30 in the lateral direction W at the inner edge 31D of the constricted portion 31. Here, the maximum length M30 of the tail hole 70 in the lateral direction W is the length of the lateral direction W of the region where the hole main body portion 71 and the notch portion 72 are combined in the tail hole 70 having the notch portion 72. In the present embodiment, it is the distance between the outer edges of the notch 72 located on the outermost side of the lateral direction W. By inserting the tail 102 into the tail hole 70 at the time of wearing, the tail hole 70 can be pulled in the lateral direction W via the tail, and the absorption core 30 is subjected to a force extending in the lateral direction W. The absorption core 30 can be expanded in the lateral direction to reduce the twist of the absorption core, and it is easy to secure the length of the absorption core 30 in the lateral direction W when worn. In particular, cats have a higher ratio of tail diameter to waist circumference than dogs. Therefore, it is easy to obtain the effect of reducing the twist of the absorption core 30 via the tail. Since the maximum length M70 of the tail hole 70 in the lateral direction W is equal to or greater than the length WD30 of the absorption core 30 of the constriction portion 31 in the lateral direction W, the force for expanding the absorption core 30 over the entire lateral direction W of the tail hole 70. Can expand the entire lateral direction W of the absorption core 30 in the constricted portion 31 when Further, since the tail hole 70 extends outward in the lateral direction from the inner edge 31D of the constricted portion 31, the absorption core 30 can be pulled from the outside in the lateral direction W, and the twist of the absorption core 30 is further suppressed. can.

The tail hole 70 may be arranged on the dorsal side of the dorsal outer edge R30 located on the dorsal side of the absorption core 30. That is, the tail hole 70 and the absorption core 30 may be separated from each other in the vertical direction Z. Since the tail hole 70 is provided in a region that does not overlap with the absorption core 30, the force that pulls the tail hole 70 laterally through the tail is not easily affected by the rigidity of the absorption core 30. Therefore, it is easier to obtain the effect of reducing the twist of the absorption core 30 via the tail.

An overlapping portion R32 (see FIG. 1) in which the core wraps 32 overlap each other may be provided in a region that overlaps with the constricted portion 31 in a plan view. The overlapping portion R32 is a region where the absorption cores 30 are not arranged and the core wraps 32 are in contact with each other. The constricted portion 31 may be difficult to maintain its rigidity as compared with the region where the absorption core 30 is not arranged and the absorption core 30 is arranged. However, by arranging the core wrap 32 so as to overlap the overlapping portion R32, the rigidity in the vicinity of the constricted portion 31 can be increased. The constricted portion 31 of the absorption core 30 can be suppressed from twisting, and the fit can be maintained.

In the stretched state of the diaper, the inner edge 17D of the fixing portion 17 of the leak-proof gather 15 in the lateral direction W may be located outside the lateral direction W of the inner edge 31D of the constricted portion 31. In the leak-proof gather 15, the upright portion 16 may stand up from the fixed portion 17, and the upright portion 16 and the entire fixed portion 17 may stand up from the absorption core 30 due to the difference in rigidity of the absorption core 30. At this time, since the inner edge 17D of the fixing portion 17 is outside the inner edge 31D of the constricted portion 31 which is the outer edge of the absorption core 30 in the region where the constricted portion 31 is provided, the inner edge 17D of the fixing portion 17 is located outside the constricted portion 31. The standing portion 16 and the entire fixed portion 17 stand up from the inner edge as a base point. In the region where the constricted portion 31 is provided, the length of the lateral W of the absorption core 30 is relatively short, and the body fluid may be guided laterally to the outside of the absorption core. Can be secured and leakage can be suppressed.

Next, the cat diaper 1X according to the modified example will be described with reference to FIGS. 6 and 7. In the following description of the modified example, the same reference numerals will be used for the same configurations as those in the above-described embodiment, and the description thereof will be omitted. FIG. 6 is a plan view of the cat diaper 1X according to the modified example as viewed from the skin surface side, and FIG. 7 is a plan view of the absorption core 30X according to the modified example. The inner edge 31D of the constricted portion 31 of the absorption core 30X according to the modified example is provided in a certain range extending in the vertical direction Z. The constricted portion 31 according to the modified example has a ventral base end edge 311 located on the ventral side, a dorsal base end edge 312 located on the dorsal side, and a side edge 33 connecting the inner edge 31D. The side edge 33 has a ventral edge F33 extending from the ventral base edge 311 to the medial edge 31D and a dorsal edge R33 extending from the dorsal base edge 312 to the medial edge 31D. The ventral edge F33 and the dorsal edge R33 are not symmetrical with respect to the lateral virtual line extending in the lateral direction W.
