Description

The present invention relates to diapers for pets.

Pets that are pets raised at home include dogs, cats, rabbits, hamsters, reptiles, insects, and fish. Among them, the weight of dogs and cats is high, and in Japan, 9 million dogs and 10 million cats are bred. Recently, the nutritional situation and living environment have improved, and both dogs and cats are aging. As a result, the number of dogs and cats requiring long-term care has increased remarkably in recent years, and the excrement such as urine pollutes the interior. In addition, dogs and cats have the property of urinating and marking the walls and furniture of the room in order to claim their territory, which also pollutes the interior.

As a conventional technique for preventing stains caused by pets, diapers for pets that can be worn so as to cover the buttocks of pets have been realized (Patent Document 1).

The pet diaper of Patent Document 1 has a diaper body, and the diaper body includes a liquid-permeable top sheet, a liquid-impermeable back sheet, and urine that is contained between the two sheets and permeates the top sheet. It has an absorber that absorbs urine, and a tail hole is formed. To be equipped with. A pair of left and right elongated fastening tapes extending outward are attached to the abdominal pad, and the diaper body is detachably fastened to the back pad with the diaper body 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 of the urethral opening of the excretory organ (forward in the excretion direction) when worn. A similar technique is also disclosed in Patent Document 2.

Dogs are not agile, but they continue to move frequently and have a lot of activity, and cats have less activity than dogs, but they move agilely. Also, due to the wild nature of dogs and cats, wearing a diaper makes them feel uncomfortable and moves to remove the diaper from their trunk. Therefore, the prior art diapers for pets have a problem that they are easily displaced to the rear side, that is, the buttocks side, which is the caudal side of the pet, when worn for a long time. When the pet diaper shifts to the rear of the pet, a gap is created between the diaper and the vicinity of the base of the pet's hind legs and the abdomen, and the excreted urine leaks from the gap. Further, when the diaper is displaced backward, leakage to the front in the urine excretion direction, that is, to the head side is likely to occur. By shifting the diaper to the rear of the pet, the diaper may even come off the pet. Conventionally, the diaper is tied to the pet's neck with a string so that the diaper does not shift backward.

In the prior art of Patent Documents 1 and 2, since the three-dimensional gathers are provided substantially parallel to the direction of the urethral meatus of the excretory organ, urine leaks from the base of the hind legs to both sides at the beginning of wearing the diaper. Can be prevented. However, if the wearing position of the diaper shifts to the rear of the pet due to wearing for a long time, the gap becomes large, the lower surface of the abdomen and the upper part of the three-dimensional gathers do not come into close contact with each other, and the excreted urine leaks out.

This problem is particularly likely to occur in pets having a body shape in which the length of the outer circumference around the waist near the base of the hind legs is extremely smaller than that around the waist near the lungs, for example, the hunting dog Dalmatian. Therefore, there is a demand for a diaper for pets that can be worn without shifting backward while being kept in close contact with the waist and the base of the hind legs regardless of the movement of the pet.

Japanese Unexamined Patent Publication No. 2004-159591 Utility Model Registration No. 3031321

An object of the present invention is to provide a pet diaper that can surely prevent urine and the like from leaking out behind the worn pet or in front of the head side without shifting.

In the present specification, the first, second and third directions X, Y and Z are for the pet diaper 1 of the first embodiment of FIGS. 1 to 11 and for the pet of the second embodiment of FIG. The direction in which the diaper 1A is unfolded in a plane without being attached to the pet 60.
The present invention is as shown in the first embodiment of FIGS. 1 to 11 and the second embodiment of FIG.
(A) The diaper bodies 2 and 2a
The length L1 of the vertical first direction X extending from the head side and the caudal side of the pet 60 to be mounted is larger than the length L2 of the horizontal second direction Y perpendicular to the first direction X, and is liquid permeable. And the surface sheet 11
A liquid-impermeable back sheet 12 bonded to the front sheet 11 and
It has a liquid absorbing absorption 13 disposed between the front surface sheet 11 and the back surface sheet 12.
An abdominal pad 18 covering the abdomen 65 is formed from the back pad 16 covering the back 64 of the trunk 61 of the pet 60 through the crotch pad 17 covering between the buttocks 63 and the left and right hind legs 66.
Diaper bodies 2 and 2a in which a tail hole 14 through which the tail 68 of the pet 60 is inserted is formed near the crotch pad portion 18.
(B) The inner portions 31 in the second direction are attached to both end portions 27 in the second direction of the abdominal pad portions 18 of the diaper main bodies 2 and 2a, respectively, and are provided so as to project outward and extend in the first direction X. An elastic member 30 having elasticity that can be elastically expanded and contracted in at least the second direction Y,
(C) Each elastic member 30 is attached to each elastic member 30 at a position deviated from each other in the first direction X on the outer portion 32 in the second direction, and is detachably locked to the back support portion of the diaper bodies 2 and 2a. The pet diapers 1 and 1A are characterized by including a plurality of locking members 40 for every 30.

According to the present invention, the second-direction inner portions 31 of each elastic member 30 are attached to both ends 27 in the second direction Y of the abdominal pad portion 18 of the diaper body 2, and the elastic member 30 is in the first direction X. It may be extended and formed, for example, in the shape of a rectangular or square rectangular plate, has elasticity that can be elastically expanded and contracted at least in the second direction Y, and has elasticity in the outer portion 32 in the second direction of each elastic member 30. A plurality of, for example, a pair of locking members 40 are attached to each elastic member 30 that is detachably locked to the backrest portion 16 at positions displaced from each other in one direction X. The inside of the second direction Y is the side closer to the diaper bodies 2 and 2a in the second direction Y, and the outside of the second direction Y is the side away from the diaper bodies 2 and 2a in the second direction Y.

Therefore, it is important that the same or substantially the same elastic tensile force acts on each of the plurality of locking members 40 that are commonly attached to each elastic member 30 by the common elastic member 30. Is. Further, the total value of the tensile forces 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 pad portion 18. Therefore, the back support portion 16 and the abdominal support portion 18 can be wrapped around the trunk 61 in the circumferential direction and tightened with a uniform or substantially uniform tightening force regardless of the position of the first direction X. As a result, for example, even if the pet 60 has a body shape in which the outer circumference of the waist circumference is smaller than the waist circumference, the tightening force is uniform in the first direction X, and for example, the waist circumference has a smaller diameter than the waist circumference. The tightening force around it does not decrease. Further, when the pet diapers 1 and 1A are attached to the pet 60, even if the tensile force by the wearer such as the owner is different for each of the plurality of locking members 40 that are displaced from each other in the first direction X, the pet diapers 1 and 1A are for pets. After wearing the diapers 1 and 1A, the trunk 61 can be tightened in the first direction with a uniform tightening force.

The present invention can be carried out not only for dogs 60 (FIGS. 10 and 11) and cats 90 (FIG. 12), which will be described later, but also for other animals as pets, and the corresponding parts of the bodies of dogs 60 and cats 90. Have the same reference mark. The dog 60 may be mainly described below, but the same applies to the cat 90.

Therefore, the pet diapers 1 and 1A do not shift to the rear of the pet 60, do not leak forward in the urine excretion direction, and leak urine from the base 67 of the hind legs 66 to both sides. It can be prevented, and the elastic member 30 can be elastically expanded and contracted according to the movement of the pet 60 wearing the pet diapers 1 and 1A, and the pet diapers 1 and 1A worn by the pet 60 are displaced and have a gap. The occurrence of diapers 1 and 1A will not come off from the pet 60. If it is assumed that individual elastic members 30 are provided for each of the plurality of locking members 40 displaced from each other in the first direction X at both ends 27 in the second direction of the abdominal pad 18 via the respective locking members 40, the body after mounting. The trunk 61 cannot be tightened in the first direction X with a uniform tightening force, and the pet diapers 1 and 1A are displaced to the rear of the pet 60, and urine leakage cannot be prevented.

By attaching the pet diapers 1, 1A through the tail 68 through the tail hole 14, it is possible to prevent the pet diapers 1, 1A from being displaced by angular displacement of the trunk 61 in the circumferential direction.

In another embodiment of the present invention, the elastic member 30 and the locking member 40 related thereto may be attached to the back support portion 16 instead of the abdominal support portion 18. In yet another embodiment of the present invention, one of the abdominal pad 18 and the back pad 16 has an elastic member 30 and one of the plurality of locking pieces 45, 46 associated therewith, eg, in the form of an elongated tape. Another elongated tape to which the locking member 40 is attached and which has the other locking piece 47, which individually and detachably locks to one of the locking pieces 45 and 46, respectively. The shaped locking member 40 may be attached to the other of the abdominal pad 18 and the back pad 16. The other locking piece 47 may be one or more.

The present invention
The tensile elastic modulus in the first direction X of each elastic member 30 is selected to be larger than the tensile elastic modulus in the second direction Y, or each elastic member 30 is characterized in that it does not have elasticity in the first direction X. And.

According to the present invention, the tensile elastic modulus (rigidity) of each elastic member 30 in the first direction X is selected to be larger than the tensile elastic modulus in the second direction Y, that is, the second direction Y is selected for the first direction X. It is harder to stretch elastically than, or does not have elasticity in the first direction X, and elastically expands and contracts only in the second direction Y, and each elastic member 30 has such elastic anisotropy. .. Therefore, each of the plurality of locking members 40 commonly attached to each elastic member 30 is subjected to the elastic tensile force in the circumferential direction of the trunk 61, which is the second direction Y, by the common elastic member 30. It acts and the component of the elastic force in the first direction X is very small or zero. Therefore, the pet diapers 1 and 1A are surely prevented from being displaced backward of the pet 60, and the leakage of urine is surely prevented.

The present invention
The locking member 40 has flexibility, is formed in an elongated shape, does not have elasticity in the length direction thereof, and has no elasticity.
The elastic limit 34 of each elastic member 30 in the second direction Y is achieved when the locking member 40 is locked to the back support portion 16 of the diaper bodies 2 and 2a and the pet diapers 1 and 1A are attached to the pet 61. Selected for the value to be
Each of the plurality of locking members 40 attached to each elastic member 30 is located at a position deviated from each other in the first direction X in the back support portion 16 of the diaper bodies 1 and 1A, and becomes a second as it becomes outward in the second direction Y. It can be locked by extending in one direction X apart from each other.
Of the plurality of locking members 40 attached to each elastic member 30, the locking member 40 on the caudal side (having the outer support piece 42 in the embodiment shown in FIGS. 1 and 2) in the mounted state. Is characterized in that both ends 27 in the second direction of the diaper main bodies 2 and 2a closely surround the vicinity of the base 67 of each hind leg 66 of the pet to achieve the wearing state.

According to the present invention, since each of the plurality of elongated locking members 40 does not have elasticity in the length direction thereof, the elastic member 30 causes the back support portion 16 and the abdominal support portion 18 to rotate around the trunk 61. It is ensured that the pet diapers 1 and 1A are wrapped in the direction and tightened in the first direction X with a uniform tightening force, so that the pet diapers 1 and 1A do not shift to the rear of the pet 60 and prevent urine from leaking. ..

The elastic limit 34 of each elastic member 30 in the second direction Y is achieved when the locking member 40 is locked to the back support portion 16 of the diapers main body 1 and 1A and the pet diapers 1 and 1A are attached to the pet 60. Since it is selected as the value to be used, it is possible to exert an appropriate tightening force on the pet 60 by exerting a so-called constant tensile force of each elastic member 30 in a fully extended state. For example, a pet diaper by selecting the elastic modulus of the elastic member 30, dimensions such as the elastic member and length, and the shape corresponding to the size of the pet 60 and therefore the length of the outer circumference of the trunk 61. It is possible to give a comfortable and reasonable tightening force to the pet 60 of each size without the 1, 1A shifting to the rear of the pet 60.

Since the locking member 40 is flexible and elongated, for example, formed in the shape of a tape, the locking member 40 is formed in a V shape (FIG. 8) at positions displaced from each other in the first direction X of the backrest portion 17. It can be extended and locked, and in particular, among the plurality of locking members 40 attached to each elastic member 30, the outermost one (outside the embodiment shown in FIGS. 1 and 2) in the mounted state. In the locking member 40 (having the support piece 42), both ends 27 in the second direction of the diaper bodies 2 and 2a closely surround the vicinity of the base 67 of each hind foot 66 of the pet 60, and the vicinity of the base 67 of the hind foot 66. It is possible to form an insertion hole 69 (FIG. 11) that can be called a leg hole through which the pet diapers can be inserted exactly, and the pet diapers 1 and 1A can be prevented from leaking urine without shifting to the rear of the pet 60. It's certain.

In the vicinity of the base 67 of the hind legs 66 surrounded by the insertion hole 69 (FIG. 11), the locking member 40 having the outermost support piece 42 (FIGS. 1 and 2) on the caudal side in the mounted state is the diaper body 2, 2a. Cover the hip bone and hip joint above the femur, along with the ends 27, and the ends 28 and 29, and cover the sartorius muscle, tensor fasciae latae muscle, etc. on the caudal side of the dog 60 rather than the internal oblique muscle. It is configured to form an insertion hole 69 (FIG. 11) and is configured to elastically tighten the waist and waist circumferences of the pet 60 to prevent the formation of gaps and reliably prevent the leakage of urine.

Further, according to the present invention, the locking pieces 45 and 46 are provided so as to surround the base 67 of the hind legs 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. With the locking member 40 included, it can be locked, for example, in a V shape (FIG. 8). Therefore, the portion around the hind legs 66 of the diapers 1 and 1A can be firmly fixed and attached to pets such as dogs 60 and cats 90. Therefore, after wearing the diapers 1 and 1A, the locking member 40 works, for example, the caudal external support piece 42, the locking piece 45, etc. The desired displacement is prevented, the back pad portion 16, the crotch pad portion 17, and the abdominal pad portion 18 of the diapers 1 and 1A do not shift to the rear of the caudal side, and urine does not leak out.

In this way, by locking the locking member 40 so that there is no gap in the insertion hole 69 (FIG. 11) which is a leg hole at the time of mounting, for example, the locking pieces 45 on the caudal side, and further 46 and 47 are engaged. Since the diapers 1 and 1A are fixed around the legs of the pets 60 and 90 by the stop, the entire diapers 1 and 1A do not shift to the rear of the caudal side. Conventional technology has not been able to prevent the diapers 1 and 1A from shifting backward, and the present invention solves this problem.

The present invention
The diaper bodies 2 and 2a have a pair of leakage prevention sheets 20, and each leakage prevention sheet 20 is
It has a base end portion 21 extending along the first direction X and attached to both end portions 27 in the second direction, and a free end portion 22 adjacent to each other in the second direction Y, and is repelled in the first direction X. It is characterized in that it can stand up from the absorber 13 so as to be stretchable.

According to the present invention, the base end portion 21 of each pair of leakage prevention sheets 20 extending along the first direction X is closer to both end portions 27 in the second direction, and therefore, at least a portion of the absorber 13 in the second direction Y. The free end portions 22 of the leakage prevention sheets 20 are attached to each other so as to be sandwiched between the two, and the absorbers 13 are exposed in the second direction Y inwardly close to each other in the second direction Y. It is elastically stretchable in the first direction X, and by standing up from the absorber 13, it is more certain to prevent urine from leaking from the vicinity of the attachment 67 of the hind legs 66 and the abdomen 65. The leakage prevention sheet 20 may be able to stand up with its free end portion 22 slightly separated from the absorber 133, but the leakage prevention sheet 20 stands up at a large angle from the absorber 13. It may be configured as follows. The free end portion 22 may be provided with an elastic material that can be elastically expanded and contracted in the first direction X, for example, a rubber cord.

In the present invention, the diaper bodies 2 and 2a of FIGS. 1 to 13 described above cover between the backrest portion 16 covering the back portion 64 of the trunk 61 of the pet 60, the buttocks 613, and the left and right hind legs 66. Pet diapers 1, 1A, and (2) are formed with an abdominal 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 is formed in the vicinity of the crotch pad 17. ) It can be carried out not only for pets but also for various diapers for humans and other applications for locking other than diapers.

The locking of the present invention is typically achieved by a planar fastener. The planar fastener is also called a fastening tape or the like. The hook-and-loop fasteners are densely brushed in a loop with one locking piece for a hook-like or mushroom-like densely brushed bond, such as Magic Tape ™. By pressing the other locking piece for adhesion, the joint can be joined so as to be attached, and the joint can be freely released. The other locking piece for looped adhesion can also be referred to as, for example, frontal tape or target tape. A planar fastener is one locking piece for bonding with an adhesive applied to one side of the film and the other locking piece for bonding, which is another film to which the adhesive can be joined and detached. It may be realized by a piece. The other locking piece for adhesion may be a brushed non-woven fabric or the like, and in a configuration in which the back sheet of the present invention is realized by such a non-woven fabric or the like, one locking piece for bonding may be used. It is not necessary to separately provide the other locking piece in order to adhere to the back sheet, and the present invention also includes these configurations. In yet another embodiment of the embodiment, in each of the outer support pieces 42, 43, one locking piece 45, 46 is provided on the other surface opposite to the one 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 a brushed non-woven fabric or the like, whereby the engagement of each end portion 27 of the diaper bodies 1, 1a in the second direction Y may be provided. Even when the stop members 40 are overlapped on the backrest portion 16, they can be detachably joined. The locking may be realized by other configurations, including connection and connection such as joining and a detachable structure thereof. It is also possible to make each of the locking pieces 45 and 46 have the same tape shape as the outer support pieces 42 and 43, omit the outer support pieces 42 and 43, and reduce the number of parts.

In this mounted state, the outer support pieces 42, 43 are displaced from each other in the first direction X in the back support portion 16 of the diaper body 2, as they move outward in the second direction Y (left side in FIG. 8). Separated from each other in the first direction X, extending in the direction of arrows 48 and 49 in a V shape, the locking pieces 45 and 46 and the locking piece 47 are locked, and the elastic member 30 is in the second direction Y. The elastic force is exerted by the tensile force acting on the diaper.

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 the diaper body 2 is attached to the dog 60, the owner grabs 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 is stretched by generating a strain ε corresponding to the tensile force of the resultant force by the external support pieces 42 and 43, as shown in the line 33. When the tensile force is equal to or higher than the elastic limit 34 of the elastic member 30 in the second direction Y, the elastic member 30 does not stretch any more even if the tensile force acts as shown in the line 35. The owner then stops further pulling and locks the locking pieces 45, 46: 47. In this way, the diaper body 2 can tighten the trunk 61 of the dog 60 and the base 67 of the hind legs 66 with a tightening force near the elastic limit 34.

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

Instead of the elastic limit 34, the proportional limit of the elastic member 30 may be used, and when the owner increases the tensile force in this way, it is possible to feel that the amount of elongation corresponding to the tensile force cannot be obtained. It can be a value.

FIG. 10 shows a state in which the pet diaper 1 is attached to the 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 as viewed from the rear, showing a state in which the pet diaper 1 is worn. In the dog 60, for example, even if the dog 60 has a body shape such as a dalmatian whose outer circumference is smaller than that around the waist, the tightening force exerted by the elastic member 30 by the diaper body 2 is uniform in the first direction X. be. Therefore, it is possible to prevent the diaper body 2 from shifting in the first direction X along the trunk 61 of the dog 60.

The locking member 40 has the outermost support piece 42 on the caudal side when the diaper body 2 is attached. It is possible to form an insertion hole 69 which can be called a leg hole through which the vicinity of the base 67 of the hind legs 66 is closely surrounded by closely surrounding the vicinity of the base 67 of the dog.

In the vicinity of the base 67 of the hind legs 66, the locking member 40 having the outermost support piece 42 (FIGS. 1 and 2) on the caudal side in the mounted state is a diaper in the V-shaped expanded state of FIG. An insertion hole 69 is formed together with the end 27 of the main body 2 and the ends 28 and 29 to cover the hip bone and hip joint above the femur, and the sartorius muscle on the caudal side of the dog 60 rather than the internal oblique muscle. , Covers the tensor fasciae latae muscle, etc., and elastically tightens the waist and waist of the dog 60. As a result, it is possible to prevent the occurrence of a gap in the vicinity of the base 67 of the hind leg 66 through which the insertion hole 69 is inserted, and to reliably prevent the leakage of urine.
In the vicinity of the base 67 of the hind legs 66 surrounded by the insertion hole 69 (FIG. 11), the locking member 40 having the outermost support piece 42 (FIGS. 1 and 2) on the caudal side in the mounted state is the diaper body 2, 2a. Along with the ends 27 and the ends 28 and 29, the scrotum and hip joints are covered above the thighbone, and the sewn muscles and femoral myocardial tension muscles are covered on the caudal side of the dog 60 rather than the medial abdominal oblique muscle. It is configured to form an insertion hole 69 (FIG. 11), and is configured to elastically tighten around the waist and waist of the pet 60, preventing the formation of gaps and reliably preventing the leakage of urine.

Further, a V-shape is formed by a locking member 40 including locking pieces 45 and 46 so that a gap is not formed in the insertion hole 69 (FIG. 11) which is a leg hole by surrounding the base 67 of the hind legs 66 with the diaper body 2. It can be locked in a shape (FIG. 8). Therefore, the portion around the hind legs 66 of the diaper 1 can be firmly fixed and attached to the dog 60. Therefore, after the diaper 1 is attached, the locking member 40, particularly the caudal outer support piece 42 and the locking piece 45, prevents undesired displacement of the dog 60 from the body, and the back of the diaper 1 The pad 16, the crotch pad 17, and the abdominal pad 18 do not shift backward on the caudal side, and urine does not leak out.

In this way, the diaper 1 is placed around the dog 60's paws by locking the locking piece 45 on the caudal side of the locking member 40 so that there is no gap in the insertion hole 69 (FIG. 11) which is the leg hole when the diaper is attached. Since it is fixed, the entire diaper 1 does not shift to the rear of the caudal side. Conventional technology has not been able to prevent the diaper 1 from being displaced backward, and the embodiment of the present invention solves this problem.

With reference to FIGS. 1 to 5 again, the diaper body 2 is a long I-shaped sheet body. The diaper body 2 is formed so that the length of the second direction Y at the center of the first direction X is smaller than the length of the second direction Y at both ends 25 and 26 of the first direction X, and the length of the first direction X. As an example, L1 is 43 cm, the length L2 of the second direction Y at both ends 25 and 26 of the first direction X is 29 cm, and the length L3 of the second direction Y at the center of the first direction X is 17 It is 0.8 cm.

The lengths L1 to L3 of the diaper body 2 are not limited to the above values. The size ratio is almost constant, and the length of L1, L2, L3 The ratio of dogs is formed to be about 10: 7: 4.

Each pair of leakage prevention sheets 20 of the diaper body 2 extends along the first direction X and is joined to the upper surface of the surface sheet 11 in FIG. 3 near both sides of the second direction Y of the absorber 13. It has a 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 elastically expand and contract in the first direction X and rise from the absorber.

Waist gathers 51 and 52 having elastic force in the second direction Y are provided on the first direction X one end 25 and the other end 26 of the diaper body 2, respectively. The flexible and stretchable sheet-like or elongated string-like elastic pieces 53, 54 for the waist gathers 51, 52 are located between the front surface sheet 11 and the back surface sheet 12 at a position higher than the absorber 13. It is arranged on the outer side near the ends 25 and 26 in one direction X.

The surface sheet 11 may be a sheet having breathability and liquid permeability, and for example, a fiber sheet made of synthetic fibers and regenerated fibers or a non-woven fabric formed by physically entwining fibers of a fiber web may be used. Can be done. In this embodiment, it is formed by using a non-woven fabric. Since the surface sheet 11 is a sheet having breathability and liquid permeability, urine can be guided to the absorber 13 from the surface sheet 11 side.

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

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

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

Any known method can be used for joining the front surface sheet 11, the back surface sheet 12, the inner support piece 41, the elastic pieces 53, 54, the leakage prevention sheet 10, and the like. It may be joined by pressurizing and heating with a melt adhesive. As the industrial glue material, TN-269 (trade name), TN-255 (trade name), TN-288 (trade name) manufactured by Moresco Co., Ltd. can be used.

The absorber 13 has a first position from a position retracted by a distance L4 from the other end 26 in the first direction of the diaper body 2 to the vicinity of the tail hole 14 with the center of the first direction X toward the one end 25 side of the first direction X. It is provided so as to retract and extend by a distance L5 on the one end 25 side 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-absorbent material can be used. The absorber 13 contains, for example, fluffy fibers, a water-absorbing polymer and a deodorant. As the fluff-like fiber, for example, cotton-like pulp obtained by stirring hydrophilic fibers obtained by cutting pulp into a length of 1 mm or more and 10 mm or less to form cotton can be used. Since the absorber 13 formed of the fluffy fibers has a large number of voids between the fibers, urine can be dispersed in the plane direction and the thickness direction and efficiently absorbed.

The water-absorbent polymer is a polymer absorber that absorbs water about 10 times or more and 300 times or less of its own weight and solidifies into a gel. For example, a water-absorbent polymer having antibacterial properties and a water-absorbent polymer having liquid permeability under load. Polymers and the like can be used. Examples of the water-absorbent polymer having antibacterial properties include the trade name Sunfresh ST-900E (manufactured by Sundia Polymer Co., Ltd.), and the water-absorbent polymer having liquid permeability under load includes the trade name Sunwet IM. -930 (manufactured by Sundia Polymer Co., Ltd.) can be mentioned. As the water-absorbing polymer, a high-performance water-absorbing polymer having antibacterial properties obtained by electrically polymerizing and adhering an antibacterial agent to a water-absorbing polymer such as a sodium acrylate salt and a potassium acrylate salt may be used. Since the water-absorbent polymer also has antibacterial properties, it is possible to suppress the growth of bacteria in the absorber 13.

By evenly dispersing the water-absorbing polymer in the absorber 13, urine from the dog 60 can be efficiently absorbed and retained regardless of which part of the surface sheet 11 permeates the urine. Can be done. By including the deodorant in the absorber 13, it is possible to prevent an unpleasant odor such as ammonia odor from leaking to the 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 in the third direction Z (FIG. 4) of 8.0 mm. The lengths L6 to L8 of the absorber 13 are not limited to the above values, but are appropriately determined depending on the size and type of the dog 60, which is the pet in which the pet diaper 1 is used, and multiple urination of the dog 60 due to physiological phenomena and markings. It suffices to have a capacity that can sufficiently absorb and retain, that is, a size and an absorption capacity. The absorber 13 can absorb and retain, for example, about 300 cc.

As shown in FIG. 3, the leakage prevention sheet 20 is a strip-shaped sheet body extending along the first direction X on the outer surface of the front surface sheet 11 and the inner surface of the back surface sheet 12. The leak prevention sheet 20 is joined to the front surface sheet 11, the back surface sheet 12, and the inner support piece 41, and has a base end portion 21 closer to the absorber 13.

The leak prevention sheet 10 has a free end portion 22 that can be elastically expanded and contracted in the first direction X. The leak prevention sheet 10 has a length direction that coincides with the first direction X and a width direction that coincides with the second direction Y in a state where the pet diaper 1 is unfolded and placed on one plane. The free end 22 of the leak prevention sheet 10 has an elastic chord 23 that is folded inward and sealed.

The leakage prevention sheet 20 can be formed by using a sheet having water impermeability and flexibility similar to the back surface sheet 12, and for example, a plurality of polypropylene threads manufactured by the spunbond method and the melt blow method can be formed. , Nonwoven fabric manufactured by the spunbond method, non-woven fabric manufactured by the melt blow method, non-woven fabric manufactured by the melt blow method, and non-woven fabric manufactured by the spunbond method are laminated in this order, and are formed by a laminated body that has been waterproofed.

The chordee 23 enclosed in the free end portion 22 of the leakage prevention sheet 20 is elastically expandable and contractible, and is in a state of being tense, that is, extended in the first direction X with respect to the front surface sheet 11 and the back surface sheet 12. Is arranged with. Therefore, when the pet diaper 1 is worn, the free end portion 22 contracts more than the base end portion 21 due to the contraction force of the chord 23, and the leakage prevention sheet 20 can stand up three-dimensionally from the surface sheet 11. Such a leak prevention sheet 20 can be called a three-dimensional gather.

Due to the elastic force of the chordee 23, the free end portion 22 of the leak prevention sheet 20 elastically contacts the buttocks 63, the abdomen 65, the vicinity of the base 67 of the hind legs 66, and the like, and urine comes into close contact with each other. Prevent it from leaking. Therefore, even if urine is released in front of the second direction Y, that is, toward the head 62 while the pet diaper 1 is attached to the dog 60, it is dammed by the leakage prevention sheet 20 and absorbed by the leakage prevention sheet 20. It is guided to the inside where the body 13 is arranged. Therefore, it is possible to prevent the urine from leaking from the second direction Y and to ensure that the urine is absorbed by the absorber 13.

As long as the chordee 23 is elastically stretchable, any known material can be used, for example, a thin trash string is used.

The waist gathers 51, 52, and therefore the bullet pieces 53, 54, are located in the first direction X from the other end 26 in the first direction to the front of the region where the absorber 13 is arranged, rather than the absorber 13. It is provided between positions separated 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 pet in which the pet diaper 1 is used, and may be in the range of 1.25 cm to 6.5 cm, and is, for example, 5.25 cm assuming a small dog. ..

The sizes of the waist gathers 51 and 52 are appropriately determined depending on the size and type of the dog 60 in which the pet diaper 1 is used. For example, the long side extending in the second direction Y is 18.5 cm to 24.0 cm, and the first A rectangular material having a short side extending in the direction X of 1.2 cm to 2.0 cm is used. For example, a rectangular elastic urethane sheet material having 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 of the first direction X stand up due to the elastic force in the direction of contraction in the second direction Y to form a standing portion having gathered folds. In addition, the standing portion of the dog 60 can be maintained in front of the excretory organ in the excretory direction by following the movement of the dog 60. Therefore, urine is guided to the region where the absorber 13 is arranged and can be reliably absorbed. Standing includes various postures that form an angle from near zero to perpendicular to the surface of the absorber 13.

The waist gathers 51 and 52 may be provided only on the side of the first direction X one end 25, or only on the side of the first direction X other end 26. The waist gathers 51 and 52, like the leak prevention sheet 20, are provided with three-dimensional gathers by enclosing elastically stretchable chordees such as a thin trash string instead of the above-mentioned elastic urethane sheet material. It may be formed.

The tail hole 14 is on the one end portion 25 side of the first direction X with respect to the absorber 13 of the front surface sheet 11 and the back surface sheet 12, and is provided substantially in the center of the second direction Y. In the present embodiment, the tail hole 14 is formed by being cut out in a convex U shape toward the one end portion 25 side of the first direction X.

Since the tail hole 14 is formed by bending the portion of the sheets 11 and 12 separated by the U-shaped notch outward in this way, the position of the pet diaper 1 is positioned with respect to the trunk 61 by the tail 68. Will be done. Therefore, it is possible to prevent the pet diaper 1 from being undesirably displaced and to maintain the fitted state of wearing. As a result, the leakage of urine can be prevented and the absorber 13 can surely absorb the urine.

The shape of the notch forming the tail hole 14 is not limited to a U shape as long as the tail 68 can be passed through, and may be a semicircular shape, but the U shape or a semicircular shape along the cross-sectional shape of the tail 68 may be used. Is preferable. The notch forming the tail hole 14 may be either a single straight line, a plurality of straight lines crossed at one point, or the like. The size and length of the notch for the tail hole 14 are appropriately determined depending on the size and type of the pet in which the pet diaper 1 is used, but the pet diaper 1 is displaced when the opening area is attached. Nikuku, the extent to which the tail 68 can be easily inserted, may be a configuration in which for example, ^{3cm 2 ~15cm} 2 about tail holes 14 are formed. Further, 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 may be joined to the outer surface of the back surface sheet 12, and may be realized by, for example, an adhesive tape having adhesiveness on both sides in another embodiment. The shape of the locking pieces 45 and 46 is not limited to a rectangular shape, and may be, for example, a square shape, another polygonal shape, or a circular shape.

Elastic chords 56 are arranged at both ends of the diaper body 2 in the second direction Y along the first direction X and in the first direction X in a tense, that is, stretched state, and contract in a natural state. The elastic chords 56 are arranged at positions on both ends of the Y in the second direction with respect to the absorber 13 and the front surface sheet 11, and are sandwiched and sealed between the back surface sheet 12 and the leakage prevention sheet 20. By sealing the chordee 56 in this way, both ends of the diaper body 2 in the second direction Y can be elastically expanded and contracted. As long as the chordee 56 is elastically stretchable, any known material can be used, for example, a thin trash string is used. The number of chords 56 is not limited, but for example, two chordees are provided at both ends of the second direction Y. By providing such a chordee 56, when the pet diaper 1 is worn, both ends of the second direction Y are three-dimensionally raised by the contraction force of the chordee 56, and the abdomen 65 is elastically surface-contacted. This will prevent the leakage of urine more reliably.

12A and 12B show a state in which the pet diaper 1 is attached to the cat 90, FIG. 12 (1) is a perspective view seen from the oblique side thereof, and FIG. 12 (2) is a perspective view seen from the rear thereof. be. The corresponding parts of the pet diaper 1 and the cat 90 in FIG. 12 are designated by the same reference numerals as those in FIGS. 1 to 11 described above. The pet diaper 1 is attached to the cat 90 as well as the dog 60 described above to prevent it from shifting backward, and in the vicinity of the base 67 of the hind legs 66, the outer support piece 42 on the most caudal side in the attached state ( The locking member 40 having FIGS. 1 and 2) forms an insertion hole 69 in the V-shaped expanded state of FIG. 8, and elastically tightens the waist and waist circumferences of the cat 90 to form a gap. Can be prevented from occurring and the leakage of urine can be reliably prevented.

Further, the locking member 40 including the locking pieces 45 and 46 is used to surround the base 67 of the hind legs 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 portion around the hind legs 66 of the diaper 1 can be firmly fixed and attached to the cat 90. Therefore, after the diaper 1 is attached, the locking member 40, particularly the locking piece 45 on the caudal side, prevents undesired displacement of the cat 90 from the body, and the back support portion 16 and the crotch of the diaper 1 are prevented. The pad 17 and the abdominal pad 18 do not shift backward on the caudal side, and urine does not leak out.

In this way, the diaper 1 is placed around the cat 90's suspension by locking the locking piece 45 on the caudal side of the locking member 40 so that there is no gap in the insertion hole 69 (FIG. 11) which is the leg hole when the diaper is attached. Since it is fixed, the entire diaper 1 does not shift to the rear of the caudal side. Conventional technology has not been able to prevent the diaper 1 from being displaced backward, and the embodiment of the present invention 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 the corresponding parts are designated by the same reference numerals. It should be noted that the inner portions of the outer support pieces 42, 43 in the second direction are displaced from each other through the slit-shaped notch 37 in the first direction X in the outer portion 32 of the elastic member 30 in the second direction. Each can be attached. The width of the slit-shaped notch 37 in the first direction X is smaller than that of the U-shaped notch 36 in FIG. 12 described above, and therefore the stress σ in the second direction Y acting on the elastic member 30 is reduced. , The tightening force near the elastic limit 34 (FIG. 9) due to the tensile force of each of the outer support pieces 42 and 43 can be increased.

FIG. 14 is a perspective view showing a part of the elastic member 30, and FIG. 15 is a cross-sectional view of a part of the elastic member 30. As an example, the elastic member 30 is formed by sandwiching an elastic film 71 with spunlaces 72 and 73 and processing it into a three-layer sheet, which can be wound into a roll shape. The elastic film 71 is a thermoplastic elastomer and may be made of a synthetic resin, for example, 200 g / m ² or less, and has an isotropic tensile modulus in the first and second directions X and Y. It expands and contracts in all directions. The spunlaces 72 and 73 eject water from a third direction Z perpendicular to the vertical one direction X while being moved on a conveyor in a state where fibers such as cotton are arranged and overlapped in one direction X by a card machine. It is a non-woven fabric that is manufactured by entwining fibers and extends in the horizontal second direction Y. This non-woven fabric has a lower tensile strength in the horizontal direction Y than the tensile strength in the vertical direction X. The non-woven fabrics constituting the spunlaces 72 and 73 may be made of synthetic resin fibers or fibers such as cotton, or may be made of a mixture thereof. The elastic member 30 is manufactured by extruding the film 71 and adhering the spunlaces 72 and 73 on both sides in a molten state. Therefore, the tensile elastic modulus of the elastic member 30 in the first direction X is larger than the tensile elastic modulus in the second direction Y, or has no elasticity in the first direction X. It is then cut to give the individual elastic member 30. The elastic member 30 may be realized by other configurations.

The present invention can be carried out in various diapers for humans as well as for pets such as the above-mentioned dog 60 and cat 90, and other uses for locking other than diapers. For example, it can be advantageously carried out to attach and connect the two separated ends of the packaging sheet in the first direction X with a uniform tensile force. A configuration in which a plurality of locking members 40 are commonly attached to an elastic member 30 according to the concept of the present invention so that a diaper or the like can be attached and detached is a diaper used by wrapping a pet in a belly band shape, and in fields other than diapers. Can be implemented in a wide range.
