Description

The present invention relates to diapers for pets.

Pets kept at home include dogs, cats, rabbits, hamsters, reptiles, insects, and fish. Among these, dogs and cats account for a large portion of the population, with 9 million dogs and 10 million cats kept in Japan. Recently, nutritional conditions and living environments have improved, and both dogs and cats are aging. As a result, the number of dogs and cats that require care has increased significantly in recent years, and their urine and other excrement pollute indoor spaces. In addition, dogs and cats have the characteristic of urinating and marking the walls and furniture of a room in order to claim their own territory, and this also stains indoor spaces.

As a conventional technique for preventing staining by pets, a pet diaper that can be worn to cover the pet's buttocks has been realized (Patent Document 1).

The pet diaper of Patent Document 1 has a diaper main body, and the diaper main body includes a liquid-permeable top sheet, a liquid-impermeable back sheet, and urine that has passed through the top sheet and is contained between the two sheets. It has an absorbent body that absorbs water, a tail hole is formed, and a belly pad that covers the abdomen from the back pad that covers the back of the pet's trunk, through the crotch pad that covers between the left and right hind legs. Equipped with A pair of left and right elongated fastening tapes extending outward are attached to the belly pad, and the diaper body is removably fastened to the back pad while being wrapped around the pet's torso and waist. The diaper body further has three-dimensional gathers provided on the diaper body so as to be substantially parallel to the direction in which the urethral orifice of the excretory organ faces (frontward in the excretion direction) when worn. A similar technique is also disclosed in Patent Document 2.

Dogs are not agile, but they continue to make small, frequent movements and have a large amount of activity. Cats are less active than dogs, but move more quickly. Also, due to their wild nature, dogs and cats feel uncomfortable when wearing diapers and move to remove the diaper from their trunks. Therefore, pet diapers of the prior art have a problem in that, when worn for a long time, the wearing position tends to shift toward the tail side of the pet, that is, toward the buttock side. When the pet diaper shifts toward the rear of the pet, a gap is created between the diaper and the pet's hind legs and abdomen, and excreted urine leaks through the gap. Furthermore, if the diaper shifts backward, urine tends to leak forward in the direction of excretion, that is, toward the head side. The diaper may even slip off the pet due to the diaper shifting behind the pet. Conventionally, a diaper is tied to the pet's neck with a string to prevent the diaper from sliding backwards.

In the prior art disclosed in Patent Documents 1 and 2, three-dimensional gathers are provided almost parallel to the direction in which the urethral opening of the excretory organ faces, so that urine leakage from the base of the hind legs to both sides is prevented when the diaper is first worn. It can be prevented. However, if the wearing position of the diaper shifts to the rear of the pet due to long-term wearing, the gap becomes larger, the lower surface of the abdomen and the upper part of the three-dimensional gathers no longer come into close contact, and excreted urine leaks out.

This problem is particularly likely to occur in pets, such as Dalmatian hunting dogs, whose circumference around the waist near the base of the hind legs is extremely small compared to the circumference around the trunk near the lungs. Therefore, there is a need for a pet diaper that can be worn snugly around the waist and the base of the hind legs, regardless of the pet's movements, and can be worn without slipping backward.

Japanese Patent Application Publication No. 2004-159591 Utility model registration No. 3031321

An object of the present invention is to provide a pet diaper that can reliably prevent urine and the like from leaking out without slipping to the rear of the pet wearing the diaper or to the front of the pet's head.

In this specification, the first, second, and third directions X, Y, and Z refer to the pet diaper 1 of the first embodiment shown in FIGS. 1 to 12 and the pet diaper 1 of the second embodiment shown in FIG. This refers to the direction in which the diaper 1A is unfolded flat without being attached to the pet 60. Corresponding entries may be indicated in parentheses ( ).
As shown in the first embodiment of FIGS. 1 to 12 and the second embodiment of FIG.
(a) A diaper main body 2, 2a,
The length L1 of the vertical first direction X extending from the cranial side to the caudal side of the pet 60 to be attached is larger than the length L2 of the horizontal second direction Y perpendicular to the first direction X, and the pet 60 is liquid permeable. A top sheet 11 having
a liquid-impermeable back sheet 12 joined to the top sheet 11;
It has an absorbent body 13 having liquid absorbing properties, which is disposed between the top sheet 11 and the back sheet 12,
Forming a belly pad 18 that covers the abdomen from a back pad 16 that covers the back 64 of the trunk 61 of the pet 60 to a crotch pad 17 that covers the buttocks 63 and between the left and right hind legs 66,
Diaper main bodies 2, 2a in which a tail hole 14 through which a tail 68 of a pet 60 is inserted is formed near the crotch part 17;
(b) Locking means 3, 3a are provided on both sides 27 of the belly pad 18 in the second direction Y, protruding outward from the diaper bodies 2, 2a (to the left in FIGS. 3 and 6). Each locking means 3, 3a is
(b1) It is attached to the second direction Y end part 27 of the abdominal support part 18, has flexibility, is elongated in the first direction X, and has elasticity in the first direction X and the second direction Y. There is no (paragraph [0036]) inner support piece 41,
(b2) Provided to extend in the first direction An elastic member 30 having elastic anisotropy that does not have elasticity in the X direction and has elasticity that can elastically expand and contract in the second direction Y,
a second direction Y inner part 31 attached to the inner support piece 41;
an elastic member 30 having a second direction Y outer portion 32 located outside the diaper body 2, 2a in the second direction Y;
(b3) A locking member 40,
(b3-1) Through the notches 36 and 37 in the first direction (Paragraph [0037], FIG. 6, FIG. 13)) are attached at mutually shifted positions, have flexibility, are elongated in the second direction Y, and are attached in the first direction X and the second direction Y. a plurality of outer support pieces 42 and 43 that do not have elasticity;
(b3-2) It has locking pieces 45 and 46 that are provided on each of the outer support pieces 42 and 43 and constitute a planar fastener that removably locks on the backrest part 16,
(b3-3) The outer support pieces 42 and 43 are placed at positions shifted from each other in the first direction The pet diaper 1, 1A is characterized in that it includes a locking means 3, 3a having a locking member 40 that extends apart from the pet and can be locked (paragraphs [0022 to 0025]).

According to the present invention, the second direction inner side portions 31 of each elastic member 30 are attached to the second direction Y both ends 27 of the belly pad portion 18 of the diaper main body 2, and the elastic members 30 are attached in the first direction For example, it may be formed into a rectangular or square rectangular plate shape, and has elasticity that can be elastically expanded and contracted at least in the second direction Y. A plurality of locking members 40, for example, a pair of locking members 40, are attached to each elastic member 30 that is removably locked to the backrest portion 16 at positions shifted from each other in one direction X. The inner side in the second direction Y is the side closer to the diaper main bodies 2, 2a in the second direction Y, and the outer side in the second direction Y is the side farther away from the diaper main bodies 2, 2a in the second direction Y.

Therefore, it is important that the same or almost the same elastic tension force is applied to each of the plurality of locking members 40 commonly attached to each elastic member 30 by the common elastic member 30. It is. Further, the total value of the tensile force acting on the plurality of locking members 40 by each elastic member 30 is equal for each elastic member 30 at both ends 27 in the second direction Y of the abdominal support portion 18 . Therefore, the back support part 16 and the abdominal support part 18 can wrap the trunk 61 in the circumferential direction and tighten it with a uniform or almost uniform tightening force regardless of the position in the first direction X. As a result, even if the pet 60 has a body shape in which the outer circumference around the waist is smaller than the circumference around the torso, the tightening force is uniform in the first direction X. The surrounding tightening force will not decrease. Furthermore, when the pet diapers 1 and 1A are attached to the pet 60, even if the pulling force applied by the wearer such as the owner is different for each of the plurality of locking members 40 mutually shifted in the first direction The diapers 1 and 1A can tighten the trunk 61 in the first direction with a uniform tightening force after being worn.

The present invention can be practiced not only with dogs 60 (FIGS. 10 and 11) and cats 90 (FIG. 12), which will be described later, as pets, but also with other animals. shall have the same reference mark. Although the dog 60 will be mainly explained below, the same applies to the cat 90.

Therefore, the pet diapers 1 and 1A do not shift behind the pet 60, urine does not leak forward in the excretion direction, and urine does not leak from the bases 67 of the hind legs 66 to both sides. The elastic member 30 can be elastically expanded and contracted in accordance with the movement of the pet 60 wearing the pet diaper 1, 1A, and prevents misalignment and gaps between the pet diaper 1, 1A worn by the pet 60. This prevents the diapers 1 and 1A from coming off from the pet 60. If each of the plurality of locking members 40 mutually shifted in the first direction It is not possible to tighten the trunk 61 with a uniform tightening force in the first direction X, and the pet diapers 1 and 1A are shifted to the rear of the pet 60, making it impossible to prevent urine from leaking out.

By putting the pet diaper 1, 1A through the tail hole 14 through the tail 68, it is possible to prevent the pet diaper 1, 1A from shifting due to angular displacement of the trunk 61 in the circumferential direction.

In other embodiments of the invention, the elastic member 30 and its associated locking member 40 may be attached to the back rest 16 instead of the belly rest 18. In still another embodiment of the present invention, one of the abdominal rest part 18 and the back rest part 16 has an elastic member 30 and a plurality of locking pieces 45 and 46 associated therewith. Another slender tape that serves as a locking partner and has a locking piece 47 that is attached to the locking member 40 and that is individually and detachably locked to one of the locking pieces 45 and 46. A locking member 40 having a shape may be attached to the other of the abdominal rest part 18 and the back rest part 16. The other locking piece 47 may be one or more.

The "locking pieces 45 and 46 constituting a planar fastener that is removably locked on the back support part 16" of the present invention are attached to the locking pieces 47 attached to the back sheet 12 in the back support part 16 of the diaper main body 2. Alternatively, the back sheet 12 may be made of, for example, a brushed nonwoven fabric, and the back sheet 16 may be detachable, including these structures (paragraph [ 0037]).

According to the invention, the tensile modulus (stiffness) of each elastic member 30 in the first direction or has no elasticity in the first direction X and elastically stretches only in the second direction Y, and each elastic member 30 has such elastic anisotropy. . Therefore, elastic tensile force in the circumferential direction of the trunk 61 in the second direction Y is applied to each of the plurality of locking members 40 commonly attached to each elastic member 30 by the common elastic member 30. The elastic force component in the first direction X is very small or zero. Therefore, it is possible to reliably prevent the pet diapers 1, 1A from shifting behind the pet 60, and to prevent urine from leaking out.

The present invention
The cutouts 37 (FIG. 13) of the outer support pieces 42 and 43 are characterized by being slit-shaped with a small width in the first direction X.
According to the present invention, the stress σ in the second direction Y acting on the elastic member 30 can be reduced, and the tightening force near the elastic limit 34 (FIG. 9) due to the tensile force of each outer support piece 42, 43 can be increased ( Paragraph [0080]).
The present invention
In each locking means 3, 3a,
The elastic limit 34 of the elastic member 30 in the second direction Y is achieved when the pet diaper 1, 1A is attached to the pet 61 with the locking member 40 locking to the back support portion 16 of the diaper main body 2, 2a. is chosen as the value
Among the locking members 40 attached to the elastic member 30, the locking member 40 that is the most caudal in the attached state (having the outer support piece 42 in the embodiment shown in FIGS. 1 and 2) is attached to the diaper main body. The second direction Y end portions 27 of 2 and 2a closely surround the base 67 of each hind leg 66 of the pet to achieve the above-mentioned attached state.

According to the present invention, each of the plurality of elongated locking members 40 does not have elasticity in the length direction, so the elastic member 30 allows the back rest part 16 and the abdominal part 18 to circumferentially surround the trunk 61. It is ensured that the pet diapers 1 and 1A are wrapped in the same direction and tightened with a uniform tightening force in the first direction .

The elastic limit 34 of each elastic member 30 in the second direction Y is achieved when the pet diaper 1, 1A is attached to the pet 60 with the locking member 40 locking to the back support portion 16 of the diaper main body 1, 1A. Since the tensile force is selected to be a constant value when each elastic member 30 is fully stretched, it is possible to apply an appropriate tightening force to the pet 60. For example, by selecting the elastic modulus of the elastic member 30, the elastic member, dimensions such as length, shape, etc., in accordance with the size of the pet 60, and therefore the outer circumference length of the trunk 61, a pet diaper can be used. 1 and 1A do not shift behind the pet 60, and a comfortable and reasonable tightening force can be applied to the pet 60 of each size.

The locking members 40 have flexibility and are elongated, for example, tape-shaped, so that they are arranged in a V-shape (FIG. 8) at mutually shifted positions in the first direction X of the back rest part 17. In particular, among the plurality of locking members 40 attached to each elastic member 30, the most caudal locking member (in the embodiment shown in FIGS. 1 and 2) is extended and lockable. The locking member 40 (having a support piece 42) is configured such that both ends 27 in the second direction of the diaper bodies 2, 2a closely surround the base 67 of each hind leg 66 of the pet 60, and An insertion hole 69 (FIG. 11), which can be called a leg hole, can be formed through which the pet diaper 1, 1A can be tightly inserted, and the pet diaper 1, 1A can be prevented from shifting behind the pet 60 and urine can be prevented from leaking. It is certain.

In the vicinity of the root 67 of the hind leg 66 surrounded by the insertion hole 69 (FIG. 11), the locking member 40 having the outermost supporting piece 42 (FIGS. 1 and 2) on the caudal side in the wearing state is attached to the diaper body 2, 2a. Together with the end portion 27 and further end portions 28 and 29, it covers the hip bone and hip joint above the femur, and covers the sartorius muscle, tensor fasciae latae, etc. on the caudal side of the dog 60 than the internal oblique muscle. It is configured to form an insertion hole 69 (FIG. 11), and is configured to elastically tighten around the waist and torso of the pet 60, thereby preventing the generation of gaps and reliably preventing urine leakage.

Further, according to the present invention, the locking pieces 45 and 46 are arranged so that the base 67 of the hind leg 66 is surrounded by the diaper main bodies 2 and 2a so that there is no gap in the insertion hole 69 (FIG. 11), which is a leg hole. The included locking member 40 allows locking, for example in a V-shape (FIG. 8). Therefore, the parts around the hind legs 66 of the diapers 1 and 1A can be firmly fixed and worn on pets such as the dog 60 and the cat 90. Therefore, after wearing the diapers 1 and 1A, the function of the locking member 40, for example, the function of the outer support piece 42 on the caudal side and the locking piece 45, prevents the body of a pet such as a dog 60 or cat 90 from coming into contact with the body. Desired displacement is prevented, the back pad 16, crotch pad 17, and stomach pad 18 of the diapers 1, 1A do not shift rearward on the caudal side, and urine leakage is eliminated.

In this way, when worn, the locking member 40 locks the locking piece 45 on the tail side, 46 and 47, etc. so that no gap is left in the leg hole 69 (FIG. 11). Since the diapers 1, 1A are fixed around the legs of the pets 60, 90 by the fasteners, the entire diapers 1, 1A do not shift rearward on the caudal side. The prior art cannot prevent the diapers 1 and 1A from shifting backwards, and the present invention solves this problem.

The present invention
The diaper body 2, 2a has a pair of leakage prevention sheets 20, and each leakage prevention sheet 20 has a
It has a proximal end 21 that extends along the first direction It is characterized by being able to stand up from the absorbent body 13 in an expandable and contractable manner.

According to the present invention, the base end portions 21 of each of the pair of leakage prevention sheets 20 extending along the first direction The free ends 22 of each leak prevention sheet 20 are close to each other in the second direction Y to expose the absorbent body 13 inside the second direction Y, and each leak prevention sheet 20 is By being elastically expandable and contractible in the first direction X and rising from the absorbent body 13, leakage of urine from the vicinity of the base 67 of the hind legs 66 and the abdomen 65 can be more reliably prevented. The leak prevention sheet 20 may be able to stand up with its free end 22 slightly away from the absorbent body 133, but the leak prevention sheet 20 may stand up apart from the absorbent body 13 at a large angle. It may be configured as follows. The free end portion 22 may be provided with an elastic material that can elastically expand and contract in the first direction X, such as a rubber string.

The present invention has the following features: (1) The diaper bodies 2 and 2a shown in FIGS. 1 to 13 cover the area from the back support part 16 that covers the back 64 of the trunk 61 of the pet 60 to the buttocks 613 and between the left and right hind legs 66. Pet diapers 1, 1A, and (2) each have a belly pad 18 that covers the abdomen 65 via the crotch pad 17, and a tail hole 14 through which the tail 68 of the pet 60 is inserted near the crotch pad 17. ) It can be implemented in various diapers not only for pets but also for humans, and for other purposes other than diapers.

The locking of the present invention is typically achieved by a hook-and-loop fastener. A sheet fastener is also called a fastening tape. A hook-and-loop fastener is a hook-like or mushroom-like fastener with one locking piece for connection that is densely brushed in a loop shape, such as Velcro (trademark), etc. By pressing the other locking piece for attachment, it can be joined so as to stick and can be freely detached from the joint. The other locking piece for loop-shaped attachment can also be called, for example, a frontal tape or a target tape. A hook-and-loop fastener consists of one locking piece for bonding, which has an adhesive applied to one side of the film, and another locking piece for attachment, which is a film that can be bonded and detached with the adhesive. It may also be realized by a piece. The other locking piece for attachment may be made of a raised nonwoven fabric, and in a configuration in which the back sheet of the present invention is made of such a nonwoven fabric, one of the locking pieces for bonding may be made of a raised nonwoven fabric. There is no need to separately provide the other locking piece for attachment to the back sheet, and the present invention also includes these configurations. In yet another embodiment, each outer support piece 42, 43 has one locking piece 45, 46 on the other side opposite to the one side on which the one locking piece 45, 46 is provided. The other locking piece that can be joined and detached may be provided, or may be made of raised nonwoven fabric, etc., so that the respective ends 27 of the diaper bodies 1, 1a in the second direction Y are locked. Even when the stopper member 40 overlaps on the back rest part 16, it can be removably joined. Locking may be achieved by other configurations, including connections such as joints, connections, and releasable structures thereof. It is also possible to make one of the locking pieces 45, 46 the same tape shape as the outer support pieces 42, 43, omit the outer support pieces 42, 43, and reduce the number of parts.

Each locking means 3 includes an elastic member 30 and a locking member 40, and is attached to both ends 27 in the second direction of the belly pad 18 near the other end 26 of the diaper body 2 on the lower side in FIG. 2 (to the left in FIGS. 3 and 6). The elastic member 30 has a second direction inner part 31 on the diaper body 2 side in the second direction Y, and has a second direction outer part 32 on the outside of the diaper body 2 in the second direction Y. Each elastic member 30 is provided extending in the first direction X, and its second direction inner side portion 31 is attached to both second direction end portions 27 of the diaper main body 2 via inner support pieces 41 .

The elastic member 30 has elasticity that can be elastically expanded and contracted at least in the second direction Y, and the tensile elastic modulus in the first direction X is selected to be larger than the tensile elastic modulus in the second direction Y. It has no elasticity in one direction.

The locking member 40 has a plurality of second direction inner parts attached to positions shifted from each other in the first direction X on the second direction outer part 32 of the elastic member 30 via a U-shaped notch 36 (this implementation In the embodiment, there are a pair of outer support pieces 42, 43, one locking piece 45, 46 is attached to each outer support piece 42, 43, and is removably locked to the backrest part 16 of the diaper main body 2. including. The outer support pieces 42 and 43 of the locking member 40 are flexible and elongated in the second direction Y (FIGS. 1, 2, 6, 8, and 13) , and are elongated in the first direction The inner support piece 41 has no elasticity in the second direction Y, and is configured in the same manner. The elastic member 30, the inner support piece 41, and the outer support pieces 42, 43 are made of synthetic resin such as polyethylene or polypropylene, and are fixed by heat fusion, for example.

The other locking piece 47 (FIGS. 2 and 7), which is removably locked to one of the locking pieces 45 and 46, is attached to the back sheet 12 of the diaper main body 2 in the backrest part 16 (FIGS. 1 and 2). can be attached to. The other locking piece 47 may be omitted when the back sheet 12 is made of, for example, a raised nonwoven fabric that is detachable from the one locking piece 45, 46. In this way, a sheet fastener is constructed. The locking piece 47 may be a single piece that locks on the plurality of locking pieces 45 and 46, but a plurality of locking pieces 47 may be individually provided on the locking pieces 45 and 46.

FIG. 7 is a perspective view showing a state in which the pet diaper 1 is worn and used. The diaper body 2 extends from a back pad 16 that covers the back 64 of the trunk 61 of the dog 60, to a crotch pad 17 that covers the buttocks 63 and between the left and right hind legs 66, and then to a belly pad 18 that covers the abdomen 65. is formed and attached.

FIG. 8 is a front view showing the locking means 3 in a state where the pet diaper 1 is attached to the dog 60. Among the plurality of outer support pieces 42 and 43 in the locking member 40, the outer support on the most caudal side (the upper part of FIGS. 1, 2, 6, and 8 showing the diaper main body 2 unfolded) in the wearing state is particularly The piece 42 has both ends 27 in the second direction of the diaper main body 2 and both ends 28 and 29 in the second direction of the belly pad 18 and the crotch pad 17 connected to the both ends 27 of the diaper body 2 , and the ends 28 and 29 of the diaper body 2 in the second direction are connected to each other of the hind legs 66 of the dog 60 . The vicinity of the base 67 is closely surrounded to form a leg hole that does not allow urine to leak out, and one locking piece 45 attached to the outer support piece 42 is extended to achieve the attached state, and one locking piece 45 attached to the outer support piece 42 is connected to the other locking piece. It is joined to the stopper piece 47. In this wearing state, the outer support pieces 42 and 43 are positioned at mutually shifted positions in the first direction The locking pieces 45 and 46 and the locking piece 47 are spaced apart from each other in the first direction It exerts elastic force when tensile force is applied to it.

FIG. 9 is a stress strain diagram for briefly explaining when a tensile force in the second direction Y is applied to the elastic member 30. When attaching the diaper body 2 to the dog 60, the owner grasps the outer support pieces 42 and 43 with his fingers and pulls them in the directions of arrows 48 and 49 (FIG. 8). As a result, the elastic member 30 expands as shown by the line 33, generating strain ε in response to the resultant tensile force of the outer support pieces 42 and 43. When the tensile force is equal to or greater than the elastic limit 34 of the elastic member 30 in the second direction Y, the elastic member 30 does not stretch any further as shown by the line 35 even if the tensile force is applied. The owner then stops pulling any further and locks the locking pieces 45, 46:47. In this way, the diaper main body 2 can tighten the trunk 61 of the dog 60, the bases 67 of the hind legs 66, etc. with a tightening force near the elastic limit 34.

Each of the plurality of outer support pieces 42 , 43 commonly attached to the second direction outer portion 32 of the elastic member 30 has the same or almost the same elastic optimum tensile force than the single elastic member 30 . given by. Therefore, the tightening force with which the diaper main body 2 tightens the trunk 61 of the dog 60 is the same value regardless of the position in the first direction X. Therefore, the diaper main body 2 attached to the dog 60 does not shift in the first direction X, and urine leakage is prevented. The elastic tensile forces exerted by the left and right pairs of elastic members 30 in FIGS. 1 and 2 are equal.

The elastic limit 34 may be replaced by a proportional limit of the elastic member 30, which has the characteristic that when the owner increases the tensile force, the owner can sense that the amount of elongation corresponding to the tensile force cannot be obtained. Any value is fine.

FIG. 10 shows a state in which the pet diaper 1 is attached to a dog 60, FIG. 10(1) is a plan view thereof, and FIG. 10(2) is a side view thereof. FIG. 11 is a perspective view of the dog 60 seen from behind, showing a state in which the pet diaper 1 is worn. Even if the dog 60 is, for example, a Dalmatian whose circumference around the waist is smaller than around the torso, the tightening force exerted by the diaper body 2 by the elastic member 30 is uniform in the first direction X. be. Therefore, the diaper main body 2 is prevented from shifting in the first direction X along the trunk 61 of the dog 60.

The locking member 40 (having the outermost supporting piece 42 on the caudal side when the diaper body 2 is attached) has both ends 27 in the second direction of the diaper body 2, and further ends 28 and 29 that are connected to each hind leg 66 of the dog 60. An insertion hole 69, which can be called a leg hole, can be formed by tightly surrounding the vicinity of the base 67 of the hind leg 66, through which the vicinity of the base 67 of the hind leg 66 is tightly inserted.

In the vicinity of the root 67 of the hind leg 66, the locking member 40 having the outermost supporting piece 42 (FIGS. 1 and 2) on the caudal side when worn is attached to the diaper when it is in use and expanded into a V-shape as shown in FIG. An insertion hole 69 is formed together with the end 27 and end parts 28 and 29 of the main body 2 to cover the hip bone and hip joint above the femur, and to cover the sartorius muscle on the caudal side of the dog 60 than the internal oblique muscle. , covering the tensor fascia latae, etc., and elastically tightening around the waist and trunk of the dog 60. This prevents the generation of a gap near the base 67 of the hind leg 66 that is inserted through the insertion hole 69, thereby reliably preventing urine from leaking out.
In the vicinity of the root 67 of the hind leg 66 surrounded by the insertion hole 69 (FIG. 11), the locking member 40 having the outermost supporting piece 42 (FIGS. 1 and 2) on the caudal side in the wearing state is attached to the diaper body 2, 2a. Together with the end portion 27 and further end portions 28 and 29, it covers the hip bone and hip joint above the femur, and covers the sartorius muscle, tensor fasciae latae, etc. on the caudal side of the dog 60 than the internal oblique muscle. It is configured to form an insertion hole 69 (FIG. 11), and is configured to elastically tighten around the waist and torso of the pet 60, thereby preventing the generation of gaps and reliably preventing urine leakage.

In addition, the diaper body 2 surrounds the base 67 of the hind legs 66 so that there is no gap in the insertion hole 69 (FIG. 11), which is a leg hole. (Fig. 8). Therefore, the diaper 1 can be attached to the dog 60 with the portion around the hind legs 66 firmly fixed. Therefore, after the diaper 1 is put on, the function of the locking member 40, especially the caudal outer support piece 42 and the locking piece 45, prevents undesired displacement with the dog's body, and the back of the diaper 1 is prevented. The abutment part 16, crotch abutment part 17, and abdominal abutment part 18 do not shift backward on the caudal side, and urine leakage is eliminated.

In this way, when wearing the diaper 1, the diaper 1 is secured around the legs of the dog 60 by locking the locking piece 45 on the tail side of the locking member 40 so that there is no gap in the leg hole 69 (FIG. 11). Since it is fixed, the entire diaper 1 will not shift backward on the caudal side. In the conventional technology, it is not possible to prevent the diaper 1 from shifting backward, and the present embodiment solves this problem.

Referring again to FIGS. 1 to 5, the diaper body 2 is a long I-shaped sheet body. The diaper main body 2 is formed such that the length in the second direction Y at the central portion in the first direction X is smaller than the length in the second direction Y at both end portions 25 and 26 in the first direction X. As an example, L1 is 43 cm, the length L2 in the second direction Y at both end portions 25 and 26 in the first direction X is 29 cm, and the length L3 in the second direction Y at the central portion in the first direction .8cm.

The lengths L1 to L3 of the diaper body 2 are not limited to the above values, and may vary depending on the pet to which the pet diaper 1 is attached, that is, whether it is a small dog or a medium-sized dog, and even if it is a small dog/medium-sized dog. However, the size ratio is almost constant, and the lengths of L1, L2, and L3 are They are formed so that the ratio of the sizes is approximately 10:7:4.

Each of the pair of leakage prevention sheets 20 of the diaper body 2 extends along the first direction X, and has a proximal end portion joined to the upper surface of the top sheet 11 in FIG. 21 and a free end portion 22 that is close to each other in the second direction Y, and the free end portion 22 can rise from the absorbent body so as to be elastically expandable and contractible in the first direction X.

Waist gathers 51 and 52 having elasticity in the second direction Y are provided at one end 25 and the other end 26 in the first direction X of the diaper body 2, respectively. Sheet-like or elongated string-like elastic pieces 53 and 54 having flexibility and elasticity for the waist gathers 51 and 52 are placed between the top sheet 11 and the back sheet 12, and It is arranged outside near the ends 25 and 26 in one direction X.

The top sheet 11 may be any sheet having air permeability and liquid permeability; for example, a fiber sheet made of synthetic fibers and recycled fibers or a nonwoven fabric formed by physically entangling the fibers of a fiber web may be used. Can be done. In this embodiment, it is formed using a nonwoven fabric. Since the top sheet 11 is a sheet having air permeability and liquid permeability, urine can be guided to the absorbent body 13 from the top sheet 11 side.

The inner surface of the topsheet 11 and the inner surface of the backsheet 12 come into contact with the absorbent core 13 in the region where the absorbent core 13 is provided. In the surrounding region where the absorber 13 is not provided, the inner surface of the top sheet 11 and the inner surface of the back sheet 12 are joined at both ends in the second direction Y.

The back sheet 12 can be formed using a liquid-impermeable and flexible sheet, and for example, a sheet made of synthetic resin such as polyethylene or polypropylene is used. Further, the back sheet 12 may be a sheet having moisture permeability in addition to liquid impermeability and flexibility. By using a sheet that also has such moisture permeability, it is possible to prevent an increase in humidity between the pet diaper 1 and the dog 60 when the pet diaper is worn, and to reduce the discomfort of the dog 60 due to stuffiness. can.

The back sheet 12 may be formed larger in size and length than the top sheet 11. The back sheet 12 is laminated in the third direction Z of the top sheet 11, and the top sheet 11, elastic pieces 53, 54, leakage prevention sheet 20, and inner support piece 41 are joined.

Any known method can be used to join the top sheet 11, back sheet 12, inner support piece 41, resilient pieces 53, 54, leakage prevention sheet 10, etc. Bonding may be performed by applying pressure and heating using a melt adhesive. As the industrial glue, TN-269 (trade name), TN-255 (trade name), TN-288 (trade name) manufactured by Moresco, etc. can be used.

The absorber 13 moves from a position retracted by a distance L4 from the other end 26 in the first direction of the diaper main body 2 to the vicinity of the tail hole 14 from the center in the first direction X toward the one end 25 side in the first direction It is retracted and extended by a distance L5 toward one end 25 in the direction. The distance L4 is, for example, 2 cm, and the distance L5 is, for example, 18.2 cm.

As the absorber 13, any known water-absorbing material can be used. The absorbent body 13 includes, for example, fluff-like fibers, a water-absorbing polymer, and a deodorant. As the fluff-like fibers, for example, floc-like pulp can be used, which is made by cutting hydrophilic fibers into lengths of 1 mm or more and 10 mm or less and stirring them into fluff-like fibers. Since the absorbent body 13 made of fluff-like fibers has many voids between the fibers, urine can be dispersed in the surface direction and the thickness direction and efficiently absorbed.

A water-absorbing polymer is a polymeric absorbent material that absorbs approximately 10 to 300 times its own weight of water and coagulates into a gel-like state. A polymer or the like can be used. An example of a water-absorbing polymer with antibacterial properties is the product name Sunfresh ST-900E (manufactured by Sundia Polymer Co., Ltd.), and an example of a water-absorbing polymer with liquid permeability under load is the product name Sunwet IM. -930 (manufactured by Sundia Polymer Co., Ltd.). As the water-absorbing polymer, a highly functional water-absorbing polymer having antibacterial properties, which is obtained by electrically polymerizing and adhering an antibacterial agent to a water-absorbing polymer such as sodium acrylate salt and potassium acrylate salt, may be used. Since the water-absorbing polymer also has antibacterial properties, the growth of bacteria in the absorbent body 13 can be suppressed.

By uniformly dispersing the water-absorbing polymer within the absorbent body 13, urine from the dog 60 can be efficiently absorbed and retained even if it permeates through any part of the top sheet 11. Can be done. By including a deodorant in the absorber 13, it is possible to prevent odors such as ammonia odor that are unpleasant to people from leaking outside.

The absorber 13 has a length L6 in the first direction X of 22.8 cm, a length L7 in the second direction Y of 9.5 cm, and a heat L8 (FIG. 4) in the third direction Z of 8.0 mm. The lengths L6 to L8 of the absorbent body 13 are not limited to the above-mentioned values, but are appropriately determined depending on the size and type of the pet dog 60 for which the pet diaper 1 is used, and are determined according to the size and type of the dog 60, which is a pet, for which the pet diaper 1 is used. It is sufficient that the material has the capacity, that is, the size and absorption ability, to sufficiently absorb and retain . The absorbent body 13 can absorb and retain approximately 300 cc, for example.

The leak prevention sheet 20 is a belt-shaped sheet body provided extending along the first direction X on the outer surface of the top sheet 11 and the inner surface of the back sheet 12, as shown in FIG. The leak prevention sheet 20 is joined to the top sheet 11, the back sheet 12, and the inner support piece 41, and has a proximal end 21 near the absorber 13.

The leakage prevention sheet 10 has a free end portion 22 that can be elastically expanded and contracted in the first direction X. The leakage prevention sheet 10 has its length direction aligned with the first direction X and its width direction aligned with the second direction Y when the pet diaper 1 is laid out and placed on one plane. The free end portion 22 of the leakage prevention sheet 10 has an elastic cord 23 folded back inward and enclosed.

The leak prevention sheet 20 can be formed using a water-impermeable and flexible sheet similar to the back sheet 12. For example, the leak prevention sheet 20 can be formed by using a plurality of polypropylene threads manufactured by a spunbond method or a melt blow method. It is formed by laminating a nonwoven fabric manufactured by a spunbond method, a nonwoven fabric manufactured by a melt blowing method, a nonwoven fabric manufactured by a melt blowing method, and a nonwoven fabric manufactured by a spunbond method in this order, and then applying waterproofing.

The cables 23 enclosed in the free end portion 22 of the leakage prevention sheet 20 can be elastically expanded and contracted, and are in a tensioned or stretched state with respect to the top sheet 11 and the back sheet 12 in the first direction X. It will be arranged in Therefore, when the pet diaper 1 is worn, the free end portion 22 contracts more than the base end portion 21 due to the contractile force of the cables 23, and the leakage prevention sheet 20 can rise three-dimensionally from the top sheet 11. Such a leak prevention sheet 20 can be called a three-dimensional gather.

Due to the elastic force of the cables 23, the free ends 22 of the leakage prevention sheet 20 come into close elastic line contact with the buttocks 63, the abdomen 65, the vicinity of the bases 67 of the hind legs 66, etc., without any gaps, and urine leaks out. Prevent leakage. Therefore, even if urine is discharged to the front in the second direction Y, that is, to the head 62 side when the pet diaper 1 is attached to the dog 60, the urine is blocked by the leakage prevention sheet 20 and absorbed by the leakage prevention sheet 20. It is guided inside where the body 13 is arranged. Therefore, urine can be prevented from leaking from the second direction Y, and the urine can be reliably absorbed into the absorbent body 13.

The cable 23 can be made of any known material as long as it can be elastically expanded and contracted; for example, a thin rubber cord can be used.

The waist gathers 51 and 52, and therefore the elastic pieces 53 and 54, are located in the first direction X from the other end 26 of the absorbent body 13 in the first direction to this side of the area where the absorbent body 13 is disposed, It is provided between positions spaced apart by a distance L11 on both sides of the second direction Y. The distance L11 is appropriately determined depending on the size and type of the pet for which the pet diaper 1 is used, and may be in the range of 1.25 cm to 6.5 cm, and if a small dog is assumed, it is, for example, 5.25 cm. .

The size of the waist gathers 51 and 52 is appropriately determined depending on the size and type of the dog 60 for which the pet diaper 1 is used, but for example, the long side extending in the second direction Y is 18.5 cm to 24.0 cm, A rectangular material with a short side extending in the direction X of 1.2 cm to 2.0 cm is used. For example, a rectangular stretchable urethane sheet material with a long side of 18.5 cm and a short side of 2.0 cm is used.

Since the waist gathers 51 and 52 are provided in this way, both ends 25 and 26 in the first direction Furthermore, it is possible to follow the movement of the dog 60 and maintain the standing portion in front of the excretory organ in the excretion direction. Therefore, urine can be guided to the area where the absorbent body 13 is provided and can be reliably absorbed. Standing up includes various postures that form an angle from close to zero to perpendicular to the surface of the absorbent body 13.

The waist gathers 51 and 52 may be provided only on the one end 25 side in the first direction, or only on the other end 26 side in the first direction. The waist gathers 51 and 52 are made of three-dimensional gathers by enclosing elastically extensible cables such as thin waste strings, similar to the leakage prevention sheet 20, instead of the above-mentioned stretchable urethane sheet material. may be formed.

The tail hole 14 is provided closer to the one end 25 in the first direction X than the absorbent body 13 of the top sheet 11 and the back sheet 12, and approximately at the center in the second direction Y. In this embodiment, the tail hole 14 is formed by notching a convex U-shape in the first direction X on the one end portion 25 side.

Since the tail hole 14 is formed by bending the parts of the sheets 11 and 12 separated by the U-shaped notches outward, the position of the pet diaper 1 is determined by the tail 68 with respect to the trunk 61. be done. Therefore, the pet diaper 1 can be prevented from undesirably shifting and can be maintained in a fitted state. This prevents urine from leaking out and allows the absorbent body 13 to reliably absorb the urine.

The shape of the notch forming the tail hole 14 is not limited to a U-shape, but may be semicircular, etc., as long as the tail 68 can pass through, but it may be a U-shape or a semicircle that follows the cross-sectional shape of the tail 68. is preferred. The notch forming the tail hole 14 may be a single straight line, a plurality of straight lines crossing each other at one point, or the like. The dimensions and length of the notch for the tail hole 14 are appropriately determined depending on the size and type of the pet for which the pet diaper 1 is used, but the opening area is such that the pet diaper 1 may shift when worn. Any configuration is sufficient as long as the tail hole 14 is formed to a size that is not difficult and allows the tail 68 to be inserted easily, for example, about 3 cm ² to 15 cm ² . Moreover, the tail hole 14 may be a through hole instead of being formed by a notch.

The locking pieces 45 and 46 of the locking member 40 only need to be bondable to the outer surface of the backsheet 12, and may be realized by, for example, an adhesive tape having adhesive properties on both sides in another embodiment. The shape of the locking pieces 45 and 46 is not limited to a rectangular shape, but may be, for example, a square shape, another polygonal shape, or a circular shape.

Elastic cords 56 are disposed along the first direction X at both ends of the diaper body 2 in the second direction Y, in a tensioned or stretched state, and are contracted in a natural state. The elastic cords 56 are arranged at positions closer to both ends in the second direction Y than the absorber 13 and the topsheet 11, and are sandwiched and sealed between the backsheet 12 and the leakage prevention sheet 20. By enclosing the cables 56 in this way, both ends of the diaper main body 2 in the second direction Y can elastically expand and contract. The cable 56 can be made of any known material as long as it can be elastically expanded and contracted, such as a thin waste cord. Although the number of cables 56 is not limited, for example, two cables are provided at each end in the second direction Y. By providing such cables 56, when the pet diaper 1 is worn, both ends in the second direction Y are raised three-dimensionally by the contraction force of the cables 56, and elastically come into surface contact with the abdomen 65. This further prevents urine leakage.

FIG. 12 shows the state in which the pet diaper 1 is attached to the cat 90, FIG. 12(1) is a perspective view of the pet diaper 1 as seen from the diagonal side, and FIG. 12(2) is a perspective view of the pet diaper as seen from the rear. be. The corresponding parts of the pet diaper 1 and the cat 90 in FIG. 12 are given the same reference numerals as in FIGS. 1 to 11 described above. The pet diaper 1 is attached to the cat 90 in the same manner as the dog 60 described above, and is prevented from slipping backward, and in the vicinity of the base 67 of the hind legs 66, the outer support piece 42 (most caudal) The locking member 40 having the structure shown in FIGS. 1 and 2) forms an insertion hole 69 in the expanded V-shape shown in FIG. The occurrence of this can be prevented, and urine leakage can be reliably prevented.

In addition, a locking member 40 including locking pieces 45 and 46 is used to surround the base 67 of the hind leg 66 with the diaper bodies 2 and 2a so that there is no gap in the insertion hole 69 (FIG. 11), which is a leg hole. It can be locked in a V-shape (Fig. 8). Therefore, the diaper 1 can be attached to the cat 90 with the portion around the hind legs 66 firmly fixed. Therefore, after wearing the diaper 1, the function of the locking member 40, especially the locking piece 45 on the tail side, prevents undesired displacement with the body of the cat 90. The abutment part 17 and the abdominal abutment part 18 do not shift backward on the caudal side, and urine leakage is eliminated.

In this way, when wearing the diaper 1, the diaper 1 is fitted around the legs of the cat 90 by locking the locking piece 45 on the tail side of the locking member 40 so that there is no gap in the insertion hole 69 (FIG. 11), which is the leg hole. Since it is fixed, the entire diaper 1 will not shift backward on the caudal side. In the conventional technology, it is not possible to prevent the diaper 1 from shifting backward, and the present embodiment solves this problem.

FIG. 13 is an enlarged front view of the locking means 3a of the pet diaper 1 which is another embodiment of the present invention. This embodiment is similar to the previous embodiment, and corresponding parts are given the same reference numerals. What should be noted is that the inner parts of the outer support pieces 42 and 43 in the second direction are located at positions shifted from each other in the first direction Each can be installed. The width of the slit-shaped notch 37 in the first direction X is smaller than that of the U-shaped notch 36 shown in FIG. , the tightening force near the elastic limit 34 (FIG. 9) due to the tensile force of each outer support piece 42, 43 can be increased.

FIG. 14 is a perspective view showing a part of the elastic member 30, and FIG. 15 is a sectional view of a part of the elastic member 30. For example, the elastic member 30 is constructed by sandwiching an elastic film 71 with spunlaces 72 and 73 to form a three-layer sheet, which can be wound into a roll. The elastic film 71 is a thermoplastic elastomer and may be made of synthetic resin, for example, is 200 g/m ² or less and has an isotropic tensile modulus in the first and second directions X and Y, Expands and contracts in all directions. The spunlaces 72 and 73 are made by using a carding machine to arrange fibers such as cotton in one direction X and stacking them on top of each other, and while moving on a conveyor, a nozzle injects water from a third direction Z perpendicular to the longitudinal direction X. It is a nonwoven fabric manufactured by intertwining fibers and extending in the second horizontal direction Y. This nonwoven fabric has lower tensile strength in the horizontal direction Y than in the vertical direction. The nonwoven fabric constituting the spunlaces 72, 73 may be made of synthetic resin fibers, cotton fibers, or a mixture thereof. The elastic member 30 is manufactured by extruding a film 71 and adhering spunlaces 72 and 73 to both sides of the film in a molten state. Therefore, the tensile modulus of the elastic member 30 in the first direction X is greater than the tensile modulus in the second direction Y, or the elastic member 30 does not have elasticity in the first direction. It is then cut to obtain individual elastic members 30. Elastic member 30 may be realized by other configurations.

The present invention can be implemented in various diapers not only for pets such as the above-mentioned dogs 60 and cats 90 but also for humans, and other uses for locking other than diapers. For example, it can be advantageously implemented to attach and connect two separate ends of a packaging sheet with uniform tension in the first direction X. The configuration in which a plurality of locking members 40 are commonly attached to the elastic member 30 according to the idea of the present invention to make diapers etc. removable can be used in diapers that are wrapped around pets in the shape of a belly band, and in fields other than diapers. Can be implemented over a wide range of areas.
