Description

The present invention relates to rabbit sheets for treating rabbit urine.

Conventionally, in order to make effective use of the space inside the cage, the rabbit toilet is generally placed at the corner of the cage, and a container with an open upper part and a right-angled triangular bottom shape in a plan view is wide. It is widespread (see Patent Document 1).

Further, it is known that the sheets installed in this rabbit toilet have a right triangle that matches the shape of the bottom surface of the container (see Patent Document 1).

Japanese Patent No. 5808444

However, since rabbits have a habit of turning their hips toward the corners and excreting, such right-angled triangular sheets mainly stain the area around the right-angled part. When the water absorption capacity near this right-angled part reached the limit, even if other parts of the same sheet were still able to absorb water, they were replaced with other sheets.

Therefore, an object of the present invention is to provide a rabbit sheet that can maintain the hygiene of a rabbit toilet container and can be used for a longer period of time.

The present invention has the following effects.

According to the invention described in the preceding paragraph [1], an absorber formed in a square sheet shape and a sheet-shaped coating material formed in a size larger than that of the absorber and covering both sides of the absorber are provided. Because it is equipped, even if one of the four corners becomes dirty, by rotating the sheets and arranging the other corners at the position where the rabbit urinates, all four corners can be used with one sheet, and by extension, the sheets can be used more. Can be used for a long time.

According to the invention described in the preceding paragraph [2], since at least four corners of the absorber are provided with water absorption strengthening portions having higher water absorption than the central portion of the absorber, any one of the four corners is provided. Even if it gets dirty, by arranging one of the other corners on the corner of the container, excrement can be absorbed more reliably in any of the four corners, and all four corners can be absorbed, so one sheet can be absorbed more. Can be used for a long time.

According to the invention described in the preceding paragraph [3], since the water absorption strengthening portion is formed in a band shape and is provided along two parallel sides of the absorber, it is the same as the feed direction of the production line. Since the absorbent polymer serving as the water absorption strengthening portion can be sprayed in the direction, the water absorption strengthening portion can be continuously provided, and thus the manufacturing work can be simplified and the manufacturing cost can be reduced.

According to the invention described in the preceding paragraph [4], since the coating material is made of a non-woven fabric having liquid permeability on both sides of the absorber, excrement can be absorbed not only from the front surface of the absorber but also from the back surface. Even if excrement flows between the rabbit sheets and the bottom surface of the rabbit toilet, the excrement can be reliably absorbed from the back surface of the rabbit sheets.

It is explanatory drawing explaining how to use the sheet for the rabbit. It is a YY cross-sectional view explaining the use method of the said rabbit sheet. (A) to (C) are front views of the rabbit sheets according to another embodiment of the present invention.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 to 4, the rabbit sheets 1 according to the present embodiment are used by laying them on the bottom surface of the rabbit toilet 2. The rabbit sheets 1 are for absorbing liquid excrement such as rabbit urine, and are mainly used as disposable products.

As shown in FIG. 1, the sheets 1 for rabbits are composed of a water-absorbent absorber 10 (a portion indicated by cross-hatching), a sheet-shaped coating material 11 that covers both sides of the absorber 10, and a coating material 11. It is a part, and is composed of a peripheral edge portion 11a provided on the outer side of the peripheral edge of the absorber 10 and a water absorption strengthening portion 12 provided at the four corners of the absorber 10.

The absorber 10 has water absorption and is formed in the form of a square sheet. The absorber 10 is formed to have a size substantially equal to that of the bottom surface of the rabbit toilet 2.

As shown in FIG. 2, the absorber 10 is formed by a plurality of layers. That is, the absorber 10 is formed by laminating a lower water-absorbent paper layer 10a made of water-absorbent paper, a pulp layer 10b, a water-absorbent layer 10c, and an upper water-absorbent paper layer 10d in this order from the lower layer to the upper layer. Further, a water absorption strengthening layer serving as a water absorption strengthening portion 12, which will be described later, is laminated on the four corners of the absorber 10.

For the lower water-absorbent paper layer 10a and the upper water-absorbent paper layer 10d, for example, highly water-absorbent fibers such as absorbent cotton, toilet paper, and tissue paper are used.

For the pulp layer 10b, a pulp material such as pulp fiber or crushed pulp is used.

The water absorption layer 10c is a layer that absorbs and retains excrement. A water-absorbent polymer, that is, a super absorbent polymer, or the like is used for the water-absorbent layer 10c. For example, a crosslinked product of polyacrylic acid, a starch or a graft polymer of cellulose and acrylic acid, a copolymer of vinyl alcohol and acrylic acid, and carboxy are used. Examples thereof include a crosslinked product of methyl cellulose and a crosslinked product of polyvinyl alcohol, and at least one or more of such water-absorbent resins are preferably used.

As shown in FIG. 1, the water absorption strengthening portions 12 are provided at the four corners of the absorber 10. The water absorption strengthening portion 12 has higher water absorption than the absorber 10, and the amount of the water absorption polymer is larger than that of the water absorption layer 10c, or a material having higher water absorption than that of the water absorption layer 10c is used. It is composed.

The water-absorbent polymer used in the water-absorbent strengthening unit 12 is the same as the water-absorbent layer 10c, for example, a crosslinked product of polyacrylic acid, a starch or a graft polymer of cellulose and acrylic acid, a copolymer of vinyl alcohol and acrylic acid, and carboxymethyl cellulose. Examples thereof include crosslinked products of polyvinyl alcohol and crosslinked products of polyvinyl alcohol, and at least one or more of such water-absorbent resins are preferably used.

The coating material 11 is formed to have a size larger than that of the absorber 10, and is attached to both sides of the absorber 10 one by one. Specifically, the covering material 11 is adhered so as to sandwich the absorber 10 from the upper and lower surfaces with an adhesive or the like, and the ends extending to the outside of the peripheral edge of the absorber 10 are bonded to each other. The end portion of the bonded covering material 11 forms a peripheral edge portion 11a provided on the outer side of the peripheral edge end of the absorber 10.

The coating material 11 is made of, for example, a non-woven fabric having liquid permeability. As the non-woven fabric, for example, various non-woven fabrics such as spunbond non-woven fabric and spunbond-melt blown-spanbond (SMS) non-woven fabric which have been hydrophilized are preferably used.

The peripheral edge portion 11a is provided with a constant width dimension over the entire peripheral edge of the peripheral edge of the absorber 10.
The width dimension of the peripheral edge portion 11a is such that the target saturated water absorption amount and water absorption are prevented so that the water-absorbent polymer that absorbs water and expands prevents the peripheral portion 11a from adhering and peeling off, and the water-absorbent polymer or the like does not jump out to the outside. It is appropriately set according to the type of sex polymer and the like.

As shown in FIGS. 3 and 4, the rabbit toilet 2 includes a container 21 having a square bottom surface and an opening at the top, and a net-like net body 22 which is stably placed so as to close the opening.

The container 21 has a bottom portion 21d having a square bottom surface and a wall portion 21a rising from the bottom portion 21d.
It includes a low wall portion 21c having a height lower than that of the wall portion 21a, and corner portions 21b formed at the four corners of the bottom portion 21d. The wall portion 21a is formed on two adjacent sides, and the low wall portion 21c is also formed on two adjacent sides, and the wall portion 21a and the low wall portion 21c are arranged diagonally. A groove 21e that engages with the net body 22 is formed at the edge of the low wall portion 21c.

The net body 22 includes a slatted top portion 22a and a leg portion 22b that stands on the bottom portion 21d of the container 21. The top portion 22a of the net body 22 is formed so as to have a height slightly lower than the edge portion of the low wall portion 21c when arranged in the container 21.

A part of the net body 22 engages with the groove 21e of the container 21, and the net body 22 is installed in the container 21.

Next, the usage method will be described. The user puts the rabbit sheet 1 on the container 21 of the rabbit toilet 2, and the rabbit sheet 1 so that the four corners (tops) of the rabbit sheet 1 are on the corner 21b of the container 21. Is laid in a container 21, and the net body 22 is installed on the rabbit sheets 1 so that the rabbit sheets 1 are pushed by the legs 22b of the net body 22. Here, a part of the net body 22 engages with the groove 21e of the container, so that the net body 22 is fixed to the container 21.

The rabbit toilet 2 on which the rabbit sheets 1 are installed is arranged at a corner of a rectangular cage (not shown) in a plan view. As a result, the rabbit excretes on the top 22a of the net body 22, and the excrement is placed on the rabbit sheets 1 laid on the bottom 21d of the container 21. In this installed rabbit toilet, the rabbit sheets 1 are located directly below the corner of the tall wall 21a (above the top 22a) because the rabbit excretes with its butt facing. The area around the right angle is dirty. If the water absorption capacity near this right-angled part reaches the limit by continuing to use it, the sheet 1 is rotated and another right-angled part is installed toward the tall wall portion 21a, and the water absorption capacity is limited. Continue to use until. When the water absorption capacity of all the right-angled parts of the sheet 1 reaches the limit, the sheet 1 is replaced with a new sheet and used again in the same manner.

Hereinafter, an example of a method for manufacturing the rabbit sheets 1 will be briefly described.

First, the lower water-absorbent paper is formed into a shape (square) suitable for the bottom shape of the rabbit toilet 2, the pulp material is supplied on the lower water-absorbent paper, and the pulp layer 10b is laminated on the lower water-absorbent paper layer 10a. Will be done. Subsequently, in the pulp layer 10b, the first water-absorbent polymer is supplied onto the pulp layer 10b, and the water-absorbent layer 10c is formed.

After that, the second water-absorbing polymer is supplied only to the portion on the water-absorbing layer 10c that is around the four corners of the square shape, and the water-absorbing reinforcing portion 12 is formed in this portion.

Subsequently, the upper water-absorbent paper is formed to have the same dimensions as the lower water-absorbent paper layer 10a, and the upper water-absorbent paper layer 10d is laminated on the water-absorbent layer 10c and the water-absorbent strengthening portion 12. At this time, the absorber 10 is formed in a square shape with the lower water-absorbent paper layer 10a, the pulp layer 10b, the water-absorbent layer 10c, and the upper water-absorbent paper layer 10d laminated.

After that, the absorber 10 is compacted by being pressed or the like, and is laminated and adhered so that both sides are sandwiched by the coating material 11 (nonwoven fabric) formed to a size slightly larger than the size of the absorber 10. To.

For example, in the coating material 11 (nonwoven fabric), a hot melt adhesive is applied to the surface on the side to be overlapped with the absorber 10, and the upper and lower coating materials 11 (nonwoven fabric) sandwiching the absorber 10 are each of the absorber 10. The absorber 10 and the coating material 11 (nonwoven fabric) are formed in an integrated state by being bonded to the surface. The integrated absorbent body 10 and the covering material 11 (nonwoven fabric) are more firmly adhered to each other by being pressed or the like to become a rabbit sheet 1 provided with the absorbent body 10 and the peripheral edge portion 11a. The rabbit sheets 1 thus obtained are folded and packed before being shipped.

The above manufacturing method is an example, and may be as follows, for example.

The first water-absorbent polymer and the second water-absorbent polymer may be the same water-absorbent polymer, or the water-absorbent polymer having high water-absorbing performance may be sprayed by the water-absorbing reinforcing portion 12. At least, the water absorption strengthening portion 12 may have a water absorption performance higher than that of the water absorption layer 10c sprayed on other parts.

The rabbit sheets 1 may be manufactured by hand as described above, or may be manufactured on a production line such as a factory.

The rabbit sheets 1 of the present embodiment have the following advantages.

That is, the rabbit sheets 1 are a water-absorbent absorbent body 10, a sheet-shaped covering material 11 that covers both sides of the absorbent body 10, and a part of the covering material 11, and are located outside the peripheral edge of the absorbent body 10. It is composed of a peripheral edge portion 11a provided and a water absorption strengthening portion 12 provided at the four corners of the absorber 10. As a result, even if one of the four corners becomes dirty, by arranging any of the other corners on the corner of the container, excrement can be absorbed more reliably in any of the four corners, and all four corners are absorbed. Therefore, one sheet can be used for a longer period of time.

Further, as described above, since the coating material 11 is made of a non-woven fabric having liquid permeability on both sides of the absorber 10, excrement can be absorbed not only from the front surface of the absorber 10 but also from the back surface, and thus for rabbits. Even when excrement has flowed between the sheets 1 and the bottom surface of the rabbit toilet 2, the excrement can be reliably absorbed from the back surface of the rabbit sheets 1.

Although the present invention has been described above based on one embodiment, the present invention is not limited to the above-described embodiment, and is appropriately modified within the scope of the invention, and may be configured as follows.
(1) In the above embodiment, the water absorption strengthening portions 12 are provided at the four corners of the absorber 10, but as shown in FIG. 5A, it is not necessary to provide the water absorption strengthening portions, and the absorber 51 and the peripheral portion 53 are provided. It is good to have and.

(2) In the above embodiment, the water absorption strengthening portions 12 are provided at the four corners of the absorber 10, but as shown in FIG. 5 (B), the water absorption strengthening portions are formed in a strip shape along two parallel sides of the absorber 61. 62 may be provided.

As a result, even if one of the four corners becomes dirty, by rotating the sheets and arranging the other corners at the position where the rabbit urinates, all four corners can be used with one sheet, and the sheets can be used longer. be able to. In addition, excrement can be absorbed more reliably.

Further, by forming the water absorption strengthening portion in a band shape, the absorbent polymer that becomes the water absorption strengthening portion can be sprayed while being fed in the production line, and the water absorption strengthening portion can be continuously provided, so that the manufacturing work is simplified and the manufacturing cost is reduced. Can be reduced.

(3) In the above embodiment, the peripheral edge portion 11a is provided at the entire peripheral edge portion of the absorber 10, but for example, as shown in FIG. 5B, the peripheral edge portion 73 is provided only on two parallel sides. Alternatively, peripheral portions may be provided only on two adjacent sides. At least the absorber 71 (which may be possessed by the water absorption strengthening portion) may have a square shape. As a result, it is possible to reduce the amount of the coating material that becomes the peripheral portion, so that the manufacturing cost can be reduced.

(4) In the above embodiment, an absorbent polymer is used as the absorber 10, but if the excrement absorbs and retains water, a material other than the absorbent polymer may be used, and a disinfectant antibacterial agent or Additives such as deodorants may be added. By adding additives, hygiene can be maintained and foul odors can be prevented.

(5) In the above embodiment, high water-absorbent fibers are used for the lower water-absorbent paper layer 10a and the upper water-absorbent paper layer 10d, but different materials may be used.

(6) In the above embodiment, a water-absorbing polymer is used for the water-absorbing reinforcing portion 12, but other than this, any excrement that absorbs and retains water may be used, for example, a water-absorbing sheet or water-absorbing laminated in a plurality of layers. Sexual paper may be used.

(7) In the above embodiment, a non-woven fabric having both sides liquid permeable is used as the coating material 11, but for example, a woven fabric, paper, or other material may be used. Further, different materials may be used for the upper surface and the lower surface.

Further, since it is easier to absorb excrement, it is preferable to use a water-permeable material on both sides. For example, a water-permeable material is used on one side and an impermeable material is used on the other side. May be good. For example, an impermeable water-repellent sheet can be used on the side of the rabbit toilet 2 that comes into contact with the bottom surface. In this case, in order to prevent excrement scattered on the wall portion 21a of the rabbit toilet 2 and the like from entering between the rabbit sheet 1 and the bottom surface of the rabbit toilet 2, pulp or water absorption is prevented. It may be configured such that the water absorption is enhanced by increasing the spraying amount of the polymer, or the peripheral edge portion 11a is brought into close contact with the wall portion 21a of the rabbit toilet 2 to stand up.

(8) In addition to the configuration of the above embodiment, for example, the surface of the rabbit sheets 1 or the absorber 10 may be embossed. Since the rabbit has the property of excreting at a predetermined position, it exceeds the permissible amount of the absorber locally by spreading the excreted local area as much as possible to the entire absorber 10 through the unevenness of the embossing process. Can be prevented. In addition, this embossing process makes it possible to spread urine more reliably by making it finer.

(9) In addition to the configuration of the above embodiment, the dimensions of the absorber 10 may be adapted to the bottom dimensions of the rabbit toilet 2 (the same dimensions or some dimensional differences may be made). As a result, the peripheral portion 11a can be raised and arranged so as to be in close contact with or in contact with the wall portion 21a of the rabbit toilet 2, and the excrement flowing down along the wall portion 21a is guided to the absorber 10 and absorbed. It is hygienic and makes it easier to dispose of excrement.
