Therefore, when the feces excreted by the pet A are received by the diaper body 1 or taken out to the outside, it can be easily handled as it is.
[0027]
6-8 illustrate a second embodiment of the present invention. In the disposable diaper for pets, a plurality of (for example, four) vent holes 21 are formed in the width direction on the back support portion 3 side of the diaper main body 1.
[0028]
In this embodiment, there are two ventilation holes 21 corresponding to the center sheet 17 of the diaper main body 1 and one ventilation hole 21 corresponding to each side sheet 18 on both sides, and each ventilation hole 21 has a tail. It is arranged closer to the backrest 3 than the first hole 19 of the hole 7. And each ventilation hole 21 is formed in the shape of a long hole in the longitudinal direction of the diaper main body 1, and from the vicinity of the fastener sheet 14, the end on the side of the abdomen pad 2 is in the vicinity of both sides of the second hole 20 of the tail hole 7. It is provided in the range to reach. The side sheet 18 and the center sheet 17 are bonded or welded by hot melt or the like in the peripheral portion of the vent hole 21, and the end of the side gather 16 on the vent hole 21 side is close to the vent hole 21. . Other configurations are substantially the same as those of the first embodiment.
[0029]
Thus, by providing the vent hole 21 on the back support part 3 side of the diaper main body 1, the inner sheet 8 and the outer sheet 9 are made of non-woven fabric having air permeability, and the air permeability on the back support part 3 side is increased. Further improvement can be achieved.
[0030]
The vent hole 21 is formed in the range where the end portion of the vent pad portion 2 of the vent hole 21 overlaps with the second hole portion 20 side of the tail hole 7 in the longitudinal direction of the diaper main body 1 from the vicinity of the fastener sheet 14. Therefore, a sufficient ventilation area can be secured.
[0031]
Moreover, since the side gathers 16 are close to the vent holes 21 and the center sheet 17 and the side sheets 18 are bonded or welded at the portions corresponding to the vent holes 21, the tail holes are formed at the final stage after the side gathers 16 are formed. As in FIG. 7, the diaper main body 1 can be punched to form the vent holes 21.
[0032]
As mentioned above, although each embodiment of this invention was explained in full detail, this invention is not limited to each embodiment, A various change is possible within the range which does not deviate from the meaning. In the first embodiment, the outer sheet 9 and the inner sheet 8 are made of non-woven fabric to ensure the breathability on the backrest 3 side, and in the second embodiment, the outer sheet 9 and the inner sheet 8 are made of non-woven fabric. Further, a ventilation hole 21 is further formed to ensure the air permeability on the backrest portion 3 side. However, when the ventilation hole 21 is formed, the outer sheet 9 is made of a material having no air permeability, such as a plastic. It is also possible to use a film or the like. Therefore, when forming the vent hole 21, the outer sheet 9 is not necessarily made of a nonwoven fabric.
[0033]
In the second embodiment, a plurality of ventilation holes 21 are formed in a long hole shape that is long in the longitudinal direction of the diaper main body 1, but a large number of small ventilation holes 21 are formed on the back support part 3 or the back support part 3. In addition, it is possible to disperse them substantially uniformly throughout the entire area of the buttocks 6. In that case, if the vent hole 21 is within a range in which excrement does not leak, it extends from the back pad portion 3 side to the buttocks pad portion 6 side, particularly the second hole portion 20 of the tail hole 7 or both sides of the first hole portion 19. It is desirable to disperse them in the range.
[0034]
In each embodiment, the urine leakage prevention film 5 is provided in a slightly wider range than the urine absorber 4 so that the air permeability of the inner sheet 8 and the outer sheet 9 can be ensured in portions other than the urine leakage prevention film 5. As long as the urine of the urine absorber 4 does not leak, it is also possible to provide the vent holes 21 on the side of the abdomen pad 2 on both sides of the urine leakage prevention film 5 in the width direction.
[0035]
If the vent hole 21 is a small hole, it may be provided in the fastener sheet 14. Further, it is desirable that the vent hole 21 is provided over a wide range over substantially the entire range excluding both ends in the width direction of the diaper body 1 so that a part thereof is located outside the side gather. The vent hole 21 may be a long hole, a round hole, or other appropriate shape. The vent hole 21 may be formed in a slit shape so as to be open when the diaper body 1 is mounted on the pet A, or may be formed so as to remain in a slit shape when mounted.
[0036]
The tail hole 7 is provided with a first hole portion 19 and a second hole portion 20 in a daruma hole shape. If this is an elongated hole shape along the longitudinal direction of the diaper body 1, an oval shape and an elongated angle shape are provided. Other hole shapes such as a hole shape may be used. When a non-woven fabric having air permeability is used for the outer sheet 9, it is necessary to provide the urine leakage prevention film 5 so that the urine of the urine absorber 4 does not leak. When the vent hole 21 is formed on the back support part 3 side of the diaper main body 1 using, etc., it is not necessary to provide the urine leak prevention film 5 because the outer sheet 9 can prevent urine leakage. The urine leakage prevention film 5 may be provided on substantially the entire width direction on the stomach pad portion 2 side. The urine absorber 4 may be provided in a range reaching the both sides in the width direction of the first hole 19 of the tail hole 7 from the side of the abdomen pad 2. The center sheet 17 and the side sheet 18 may be configured by a single inner sheet 8.
[0037]
【The invention's effect】
In the present invention, because it made to have at least the back pad 3 side to the breathability of the diaper body 1, it is possible to reduce the stuffiness of the pet A in the mounted state, spend comfortable pet A also is in the hot season of summer, etc. There are advantages. The tail hole 7 is arranged on the side of the abdomen 2 and is a first hole having a size such that feces excreted from the pet A do not adhere to the diaper body 1 when the tail hole 7 is made to correspond to the anus C of the pet A. 19 and a second hole 20 that is continuous with the back pad 3 side of the first hole 19 so that the first hole 19 corresponds to the anus C of the pet A when passing through the tail B of the pet A. Since the diaper main body 1 receives the feces excreted by the pet A or removes it from the outside, the mounting position of the diaper main body 1 on the pet A is changed up and down. It is possible to easily cope with this.
[0038]
In addition, since a non-woven fabric having air permeability is used for at least the back support portion 3, it can be easily manufactured as in the case of using a non-breathable sheet material although the air permeability can be secured.
[0039]
Further, the diaper main body 1 includes a nonwoven fabric inner sheet 8 and an outer sheet 9 provided on both the inner and outer sides of the diaper main body 1 over substantially the entire length of the belly pad portion 2 and the back pad portion 3, and the inner sheet 8. Since the urine absorber 4 interposed between the urine absorber 4 and the outer sheet 9 and the urine leakage prevention film 5 interposed between the urine absorber 4 and the outer sheet 9 are provided, air permeability can be ensured. At the same time, leakage of urine can be prevented. Further, by providing the vent hole 21 in the back pad part 3, the air permeability of the back pad part 3 can be improved.
