Description

  The present invention relates to a pet diaper.

  In recent years, an increasing number of people keep pets, which are pets such as dogs and cats, indoors. Pets not only perform urination as a physiological phenomenon, but also as markings to assert their territory, so when pets are kept indoors, urination occurs on the walls and furniture of the room. There is a problem that indoors are soiled.

  Such indoor urination can be practiced in place by training if it is an adult dog, but in the case of a puppy that has just been born, a young dog under one year old, or an old dog There is a problem that is difficult. As a conventional technique for solving such a problem, for example, Patent Document 1 discloses a technique related to a pet diaper that can be mounted so as to cover a pet's buttocks.

  The pet diaper described in Patent Document 1 is made of an I-shaped water-absorbing material whose back surface is covered with a thin polyethylene film, and a removable adhesive tape is attached to both sides of one end, and the inner side of the other end A tail hole is provided at the center of the second end, and an adhesive tape connected to the removable adhesive tape is attached to both sides of the other end. The tail of the pet is passed through the tail hole, and the back side of the pet The removable adhesive tape is connected to the adhesive tape and attached to the pet.

  However, since the removable adhesive tape can be connected only to a certain area of the adhesive tape, a dimensional difference around the waist can be allowed only by the size of the adhesive tape. Therefore, since the range of the waist circumference that can be handled by one size pet diaper is narrow, there is a problem that it is necessary to manufacture a large number of diapers in order to deal with a plurality of pets having different sizes.

  Moreover, the pet diaper according to the prior art can be attached to the pet without causing a gap that causes urine to leak when the attached pet has a certain size around the waist.

  However, the size of the conventional diaper for a pet can be shortened only to the point where the edges on the opposite side of the detachable pressure-sensitive adhesive tape are connected to the water-absorbing material. Therefore, since there is a limit to the size that can be handled, there is a problem that it is difficult to wear a pet with a very short girth, such as a small dog or cat, so as not to cause a shift or a gap.

For example, a fiber sheet made of synthetic fiber and regenerated fiber or a nonwoven fabric formed by physically entanglement of fibers of a fiber web may be used. Can do. In this embodiment, it is formed using a nonwoven fabric. Since the inner sheet 5 is a sheet having air permeability and liquid permeability, urination can be guided to the absorber 7 from the inner sheet 5 side.

  The inner sheet 5 is not joined to the outer sheet 6 in the region where the absorber 7 and the reinforcing sheet 10 are provided, and in the region where the absorber 7 and the reinforcing sheet 10 are not provided, One main surface 5 a and one main surface 6 a of the outer sheet 6 are joined. In the region where the absorbent body 7 and the reinforcing sheet 10 are provided, the one main surface 5a of the inner sheet 5 is in contact with only the absorbent body 7 and the reinforcing sheet 10.

  The other main surface 5 b which is the other surface of the inner sheet 5 is in contact with only the leakage prevention sheet 8. The one main surface 5a and the other main surface 5b are both surfaces in the thickness direction (third direction Z) of the inner sheet 5, and the one main surface 5a is a surface opposite to the other main surface 5b in the third direction Z. . Further, the one main surface 6a and the other main surface 6b of the outer sheet 6 are both surfaces in the thickness direction (third direction Z) of the outer sheet 6, and the one main surface 6a is the same as the other main surface 6b in the third direction Z. This is the opposite side.

  In the present embodiment, the inner sheet 5 is formed to have a smaller dimension in the second direction Y than the outer sheet 6, and is laminated and bonded in the third direction Z of the outer sheet 6.

  The outer sheet 6 can be formed using a liquid-impervious and flexible sheet or the like. In the present embodiment, for example, a polyethylene sheet is used. The outer sheet 6 may be a sheet having moisture permeability in addition to liquid impermeability and flexibility. By using such a sheet having moisture permeability, an increase in humidity between the pet diaper 1 and the pet can be prevented at the time of wearing, and the discomfort of the pet due to stuffiness can be reduced.

  In the present embodiment, the outer sheet 6 is formed with a dimension in the second direction Y larger than that of the inner sheet 5, and is joined to the inner sheet 5, the reinforcing sheet 10, and the leakage prevention sheet 8.

  When the outer sheet 6 is joined to the inner sheet 5, the reinforcing sheet 10, and the leakage prevention sheet 8, the longitudinal direction, the width direction, and the thickness direction of the outer sheet 6 are the longitudinal directions of the inner sheet 5 and the leakage prevention sheet 8. , Which coincides with the width direction and the thickness direction.

  Any known method can be used for joining the inner sheet 5, the outer sheet 6, the reinforcing sheet 10, and the leakage prevention sheet 8. In this embodiment, for example, a hot-melt adhesive that is an industrial paste is used. The sheets 5, 6, 8, and 10 are joined by pressurizing and heating. As the industrial paste, TN-269 (trade name), TN-255 (trade name), TN-288 (trade name) and the like manufactured by Moresco can be used.

  The absorber 7 is disposed between the inner sheet 5 and the outer sheet 6, has a rectangular shape and liquid absorbency, and has a function of holding the absorbed liquid. The absorber 7 is disposed at a substantially central portion in the second direction Y at a position retracted to the first direction X other end 2B side than the edge 4A of the first direction X one end 2A.

  In the present embodiment, the absorber 7 slightly exceeds the center in the first direction X toward the first direction X other end 2B side from the position retracted toward the other end 2B in the first direction X with respect to the edge 4A. Provided over different positions. More specifically, the distance L4 is retracted from the edge 4A toward the other end 2B, and the distance L5 is retracted from the edge 4B of the other end 2B toward the one end 2A. In the present embodiment, the distance L4 is 2.0 cm, and the distance L5 is 13.4 cm.

  The position where the absorber 7 is provided is not limited to the above range, and, for example, from the position retracted to the first direction X other end 2B side than the end edge 4A to the end edge 4B of the first direction X other end 2B. It may be arranged, and may be arranged from the position retracted to the first direction X other end 2B side from the edge 4A to the center in the first direction X.

  The size and absorption capacity of the absorbent body 7 are appropriately determined depending on the size and type of the pet in which the pet diaper 1 is used, but sufficiently absorb and retain the urine of the pet multiple times due to physiological phenomena and markings. Any size and absorption capacity can be used.

  Any known water-absorbing material can be used as the absorber 7. In the present embodiment, the absorbent body 7 includes fluff-like fibers, a water-absorbing polymer, and a deodorant. As the fluffy fiber, for example, a cotton-like pulp obtained by stirring a hydrophilic fiber obtained by cutting a pulp into a length of 1 mm or more and 10 mm or less to form a cotton-like shape can be used. Since the absorber 7 is formed of fluff-like fibers, the absorber 7 has a large number of voids between the fibers. Therefore, the liquid can be efficiently moved and absorbed in the surface direction and the thickness direction.

  The water-absorbing polymer is a polymer absorber that absorbs moisture of about 10 to 300 times its own weight and solidifies in a gel state. As the water-absorbing polymer, for example, a water-absorbing polymer having antibacterial properties or a load-removing polymer. A water-absorbing polymer having liquid properties can be used. As an example of the water-absorbing polymer having antibacterial properties, trade name Sun Fresh ST-900E (manufactured by Sundia Polymer Co., Ltd.) can be mentioned. As the water-absorbing polymer having liquid permeability under load, trade name Sun Wet IM-930 (manufactured by Sundia Polymer Co., Ltd.) can be mentioned. In this embodiment, 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 sodium acrylate and potassium acrylate is used. Yes. As described above, the water-absorbing polymer also has antibacterial properties, so that the growth of bacteria in the absorbent body 7 can be suppressed.

  In this embodiment, the water-absorbing polymer is evenly dispersed in the absorbent body 7. By being configured in this way, even when pet urine penetrates from any part on the inner sheet 5, it can be efficiently absorbed and retained. Moreover, by disperse | distributing a deodorizing agent uniformly in the absorber 7, it can prevent that a smell unpleasant for people, such as an ammonia smell, leaks outside.

  In the present embodiment, the absorber 7 has a distance L6 in the first direction X of 14.6 cm, a distance L7 in the second direction Y of 6.0 cm, and a distance L8 in the third direction Z of 8.0 mm. The distances L6 to L8 of the absorbent body 7 are not limited to the above numerical values, but are determined as appropriate depending on the size and type of the pet in which the pet diaper 1 is used, and sufficient urination of the pet due to physiological phenomena and marking as described above is sufficient. It is only necessary to have a capacity that can be absorbed and held in the body, that is, size and absorption capacity.

  The leakage prevention sheet 8 is a belt-like sheet body that extends along the first direction X on the other main surface 5 b of the inner sheet 5, one main surface 6 a of the outer sheet 6, and one main surface of the reinforcing sheet 10. is there. The leakage prevention sheet 8 has one end in the width direction formed as a base end joined to the other main surface 5b of the inner sheet 5, the one main surface 6a of the outer sheet 6, and the one main surface of the reinforcing sheet 10. The other end portion is formed as a free end portion that can elastically expand and contract. The longitudinal direction of the leakage preventing sheet 8 coincides with the first direction X when the pet diaper 1 is developed and placed on a horizontal plane, and the width direction is developed by placing the pet diaper 1 on a horizontal plane. In the second direction Y. The free end portion of the leakage prevention sheet 8 is folded inward, and the rope 12 described later is enclosed therein.

  The leakage prevention sheet 8 can be formed using a sheet having water impermeability and flexibility in the same manner as the outer sheet 6. For example, a plurality of polypropylene nonwoven fabrics manufactured by a spunbond method and a melt blow method are used. The non-woven fabric manufactured by the spunbond method, the non-woven fabric manufactured by the melt blow method, the non-woven fabric manufactured by the melt blow method, and the non-woven fabric manufactured by the spun bond method are laminated in this order, and the non-woven fabric is waterproofed. The leakage prevention sheet 8 is a so-called three-dimensional gather.

  At the free end of the leakage prevention sheet 8, the elastically stretchable cable 12 is tensioned in the first direction X with respect to the inner sheet 5 and the outer sheet 6, that is, encased in an extended state. The free end is elastically extendable. Therefore, when the pet diaper 1 is mounted, the free end portion contracts more than the base end portion due to the contracting force of the rope 12, and the leakage preventing sheet 8 is raised in three dimensions.

  Thus, when the leakage prevention sheet 8 rises in three dimensions, for example, when the pet diaper 1 is attached to a pet, if urination spreads in the second direction Y, the leakage prevention sheet 8 is clogged by the leakage prevention sheet 8; Since it will be guide | induced to the absorber 7 along the leakage prevention sheet 8, while preventing urination from leaking out from the 2nd direction Y, a urination can be made to be absorbed into the absorber 7 reliably.

  As long as the rope 12 can be elastically expanded and contracted, any known material can be used, and a thin rubber string is used in the present embodiment.

  The reinforcing sheet 10 is provided between the inner sheet 5 and the outer sheet 6 and is made of a material having flexibility and stretchability. Among the main surfaces in the thickness direction (third direction Z), the reinforcing sheet 10 has one main surface facing the one main surface 5a of the inner sheet 5 and the leakage prevention sheet 8, and the other main surface is the outer surface 6 of the outer sheet 6. On the other hand, it arrange | positions so that the main surface 6a may be opposed, and it joins with the inner sheet | seat 5, the outer sheet | seat 6, and the leakage prevention sheet | seat 8. FIG. Moreover, in this embodiment, the reinforcement sheet 10 is not provided in the area | region near the 2nd direction Y both ends 13 and 14, but is provided only in the range containing the 2nd direction Y center part.

In the second direction Y, it is provided from a position separated from the one end 13 by a predetermined distance L11 to a position separated from the other end 14 by a predetermined distance L11. In the state where the pet diaper 1 is deployed, the other reinforcing sheet 10 is provided at a position symmetrical to the one reinforcing sheet 10 with respect to the center of the pet diaper 1.

  The distance L11 is appropriately determined depending on the size and type of the pet in which the pet diaper 1 is used, and may be in the range of 1.0 cm to 1.5 cm. In the present embodiment, the distance L11 is 1.25 cm.

  The size of the reinforcing sheet 10 is appropriately determined depending on the size and type of the pet in which the pet diaper 1 is used. For example, a rectangular material having a long side of 18 cm to 19 cm and a short side of 1.2 cm to 2.0 cm is used. Is used. In this embodiment, rectangular stretchable urethane having a long side of 18.5 cm and a short side of 2.0 cm is used. In the present embodiment, the longitudinal direction (long side direction) of the reinforcing sheet 10 matches the second direction Y, the width direction (short side direction) matches the first direction X, and the thickness direction is the third direction. Matches Z.

  In this embodiment, the reinforcing sheet 10 is provided on both sides of the pet diaper 1 on the first direction X one end 2A side and the other end 2B side, but in other embodiments, only the first direction X one end 2A side is provided. Or may be provided only on the first direction X other end 2B side.

  The notch 11 is a notch for forming a hole for bringing the tail of the pet to the outside at the time of wearing, and is closer to the other end 2B side in the first direction X than the absorber 7 of the inner sheet 5 and the outer sheet 6. , Provided in the approximate center of the second direction Y. In this embodiment, the cut 11 is formed by cutting the inner sheet 5 and the outer sheet 6 into a U shape.

  Since the cut 11 is thus formed, the pet diaper 1 can be attached to the cut 11 through the tail of the pet. Therefore, since the position of the pet diaper 1 is fixed by the tail, it is possible to prevent the pet diaper 1 from being undesirably displaced, prevent leakage of urine, and allow the absorbent body 7 to reliably absorb the diaper 1. .

The shape of the incision 11 may be any of a semicircular shape, a single straight line, and a plurality of straight lines crossed at one point as long as it can be passed through the tail. Therefore, a U-shape or a semicircular shape is preferable. The dimensions of incision 11 is appropriately determined depending on the size and type of pet pet diaper 1 is used, the opening area may be a 3cm ² ~15cm ^2. Further, instead of forming the notch 11, a previously opened hole may be formed.

  In the second direction Y both ends 9A and 9B of the diaper main body 2, the rope 15 is arranged along the first direction X and in the first direction X, that is, in a stretched state. More specifically, it is disposed between the outer sheet 6 and the leakage prevention sheet 8 so as to be enclosed in positions in the second direction Y both end portions 9A and 9B side with respect to the absorber 7 and the inner sheet 5. . By thus enclosing the rope 15, the second direction Y both ends 9 </ b> A and 9 </ b> B can elastically expand and contract.

  As long as the rope 15 can be elastically expanded and contracted, any known material can be used. In the present embodiment, a thin rubber string is used. Further, the number of the ropes 15 is not limited as long as it can be elastically expanded and contracted, but in the present embodiment, two pieces are provided at each of the end portions 9A and 9B. By providing such a cord 15, when the pet diaper 1 is mounted, the second direction Y both ends 9 </ b> A and 9 </ b> B are raised three-dimensionally by the contraction force of the cord 15, so-called leg gathers are formed.
