Technical Field

[0001] The present invention relates to a urine treatment material.

Background Art

[0002] The inventor has proposed a urine treatment material (hereinafter referred to as "conventional example") disclosed in Patent Documents 1 and 2 as a urine treatment material used in toilets for pets such as cats and dogs.

[0003] This conventional example includes an ammonia neutralization treatment unit that allows the passage of urine and neutralizes ammonia in the urine, and a urine absorption unit provided below the ammonia neutralization treatment unit that absorbs the neutralized urine that has passed through the ammonia neutralization treatment unit. The ammonia neutralization treatment unit is composed of a urine diffusion sheet that absorbs urine and diffuses it by capillary action, and an ammonia neutralizing material provided below the urine diffusion sheet that neutralizes ammonia.

[0004] Therefore, for example, urine that has fallen into the ammonia neutralization treatment unit is neutralized when passing through the ammonia neutralization treatment unit.

Embodiments for Carrying Out the Invention

[0028] Preferred embodiments of the present invention will be briefly described based on the drawings, showing the operation of the present invention.

[0029] For example, urine 60 introduced from the upper surface side is absorbed by the urine diffusion sheet 1 and diffuses while passing to the lower surface side. At this time, since the urine diffusion sheet 1 is configured by impregnating and drying an ammonia neutralizing material solution 3' containing an ammonia neutralizing material for neutralizing ammonia, the ammonia neutralizing material is uniformly dispersed and arranged in the urine diffusion sheet 1, and the ammonia neutralizing treatment ability is uniform throughout the urine treatment region in the urine diffusion sheet 1, and a good ammonia neutralizing treatment ability is exhibited.

Examples

[0030] <Example 1> Specific Example 1 of the present invention will be described with reference to the drawings.

[0031] This example is a urine treatment material X that allows the passage of urine 60 and neutralizes ammonia in urine 60. Note that this example is configured to be used in a pet toilet 50, but is not limited thereto.

[0032] Specifically, the urine treatment material X includes a urine diffusion sheet 1 that absorbs urine 60 introduced from the upper surface side as shown in FIG. 1 and allows it to pass to the lower surface side while diffusing.

[0033] In this example, the urine diffusion sheet 1 is composed of a white paper material (sheet base material 1') that is 100% pulp (paper fiber), and this urine diffusion sheet 1 (sheet base material 1') has extremely excellent water absorption performance and liquid diffusion performance.

[0034] Therefore, when urine 60 is introduced into the urine diffusion sheet 1 from the upper surface side, it will quickly diffuse in the radial direction and pass to the lower surface side. Since the urine diffusion sheet 1 is white, for example, when treating the urine of pet C, it is easier to judge whether it is sick based on the color of urine 60.

[0035] In addition, a large number of recesses 2 are provided on the surface of this urine diffusion sheet 1 (sheet base material 1') by pressing (for example, debossing). These recesses 2 are recesses in a circular shape in plan view, in which a side wall portion 2a stands vertically on the periphery of a circular bottom wall portion 2b, and the bottom wall portion 2b of this recess 2 is provided to be thinner than the side wall portion 2a.

[0036] Therefore, when urine 60 is introduced into the urine diffusion sheet 1 from the upper surface side, since the bottom wall portion 2b of the recess 2 is thinner than other parts (side wall portion 2a), urine 60 will pass through first. The urine 60 introduced into the urine treatment material X will immediately diffuse and pass through without forming a urine pool (see FIG. 2). Also, since the surface area becomes wider, the ammonia neutralization treatment ability is improved.

[0037] Figure 3 shows that a large number of recesses 2 and 2' are provided on the front and back surfaces of the urine diffusion sheet 1 (sheet base material 1') by pressing (for example, embossing). These recesses 2 and 2' are recesses in a circular shape in plan view, where side walls 2a and 2a' rise vertically at the periphery of circular bottom wall portions 2b and 2b'. In this case, the side walls 2a and 2a' of these recesses 2 and 2' are provided to be thinner than the bottom wall portions 2b and 2b'.

[0038] Therefore, when urine 60 is introduced onto the upper surface side of the urine diffusion sheet 1, since the side walls 2a and 2a' of the recess 2 are thinner than other parts (bottom wall portion 2b), urine 60 will pass through first. The urine 60 introduced into the urine treatment material X will immediately diffuse and pass through without forming a urine pool (see Figure 4). Also, since the surface area becomes larger, the ammonia neutralization treatment ability is improved.

[0039] Note that as a processing method for providing the recesses 2 and 2', either molding or cutting may be used.

[0040] Figure 6 shows a urine treatment material X composed of a urine diffusion sheet 1 (sheet base material 1') without recesses 2 and 2' provided on the front and back surfaces. Since a thin sheet base material 1' can be adopted, urine 60 can pass through quickly to the same extent even without providing the recesses 2 and 2'.

[0041] Also, an ammonia neutralization treatment portion 3 (shown in gray in the figure) is provided throughout the entire area of this urine diffusion sheet 1, which is formed by impregnating and drying an ammonia neutralization material solution 3' (shown in gray in the figure) containing an ammonia neutralization material for neutralizing ammonia. Note that the entire area of the urine diffusion sheet 1 (sheet base material 1') impregnated and dried with the ammonia neutralization material solution 3' refers to all areas within the range (urine treatment area) required for treating urine 60 (neutralizing ammonia), and it is not necessarily limited to being provided over the entire urine diffusion sheet 1 (sheet base material 1').

[0042] In this embodiment, the ammonia neutralization treatment portion 3 is provided in the urine diffusion sheet 1 by an ammonia neutralization treatment portion forming apparatus H1, which will be described later.

[0043] As shown in Figure 5, this ammonia neutralization treatment device H1 is composed of a sheet payout section 10 located on the upstream side of the device for paying out a long rolled up urine diffusion sheet 1 (sheet substrate 1'), a sheet collection section 11 located on the downstream side of the device for rolling up and collecting the urine diffusion sheet 1 (urine treatment material X), and a liquid application section 12 and a drying section 13 located between the sheet payout section 10 and the sheet collection section 11.

[0044] The liquid application section 12 is configured such that a valved liquid supply pipe section 12b is suspended from a liquid storage tank 12a which stores an ammonia neutralizing solution 3', and a roller body 12c is rotatably provided at the lower part of this liquid supply pipe section 12b. This roller body 12c is configured by fitting a cylindrical sponge member 12c" onto a rotating shaft section 12c' which is connected in a liquid-passing state to the lower end of the liquid supply pipe section 12b and has liquid outlet holes on its circumferential surface.

[0045] In this embodiment, two roller bodies 12c to which the ammonia neutralizing solution 3' is supplied from the liquid storage tank 12a are arranged side by side in the transport direction of the urine diffusion sheet 1 (sheet base material 1'), and further, at a position opposite to and below each of the roller bodies 12c, a support roller body 12d is provided which clamps and supports the urine diffusion sheet 1 (sheet base material 1') together with the roller body 12c.

[0046] The liquid drying section 13 is configured to deliver hot air to the urine diffusion sheet 1 (sheet substrate 1') being transported to dry the ammonia neutralizing agent solution 3' impregnated in the urine diffusion sheet 1 (sheet substrate 1').

[0047] Reference numeral 14 denotes a compaction roller, and 15 denotes a tension roller.

[0048] Therefore, in the ammonia neutralization treatment unit forming apparatus H1, the urine diffusion sheet 1 (sheet base material 1') is fed out from the sheet feeding unit 10, and the surface of the urine diffusion sheet 1 (sheet base material 1') is impregnated with the ammonia neutralizing material solution 3' up to the inside of the urine diffusion sheet 1 (sheet base material 1') by the rolling of the roller body 12c in the liquid application unit 12. Subsequently, the urine diffusion sheet 1 (sheet base material 1') impregnated with the ammonia neutralizing material solution 3' passes through the drying unit 13 and is dried. After this dried urine diffusion sheet 1 is roll-pressed, it is collected by the sheet collection unit 11. Thereafter, the long urine diffusion sheet 1 collected by the sheet collection unit 11 is cut into a predetermined length (rectangle) to become the urine treatment material X, and a fixing double-sided tape (not shown) is provided on the lower peripheral edge of each of the cut urine treatment materials X.

[0049] The ammonia neutralizing material solution 3' used in this embodiment is obtained by mixing powdered (or granular) citric acid (manufactured by Center Valley Co., Ltd.) as an ammonia neutralizing material that is dissolved by urine 60 to neutralize (decompose) ammonia and water, and moderately removing moisture to have an appropriate viscosity (sol state).

[0050] The viscosity of this ammonia neutralizing material solution 3' is set to an appropriate viscosity such that when the ammonia neutralization treatment unit 3 is provided on the urine diffusion sheet 1 (sheet base material 1') by the above-described ammonia neutralization treatment unit forming apparatus H1 and the ammonia neutralization treatment unit forming apparatus H2 described later, the ammonia neutralizing material solution 3' impregnated up to the inside of the urine diffusion sheet 1 (sheet base material 1') is entangled with the paper fibers and stays.

[0051] Fig. 7(a) is an electron micrograph (magnification: 500 times) of the surface of the sheet base material 1', and Fig. 7(b) is an electron micrograph (magnification: 500 times) of the surface of the urine diffusion sheet 1. It can be seen that the ammonia neutralizing material in the form of xerogel (dry agar state) is entangled with the paper fibers and arranged in a state of filling the gaps between the paper fibers.

[0052] In addition, the ammonia neutralization treatment section 3 provided by impregnating and drying the ammonia neutralizing material solution 3' immediately dissolves when it comes into contact with urine 60 (moisture), and neutralization treatment is performed by the ammonia neutralizing material (citric acid) not only on the surface layer but also in the entire area such as the middle layer and the lower layer in the ammonia neutralization treatment section 3.

[0053] In addition, a coating sheet 4 that absorbs and diffuses the urine 60 introduced from the upper surface side and allows it to pass to the lower surface side may be laminated on the surface of the urine diffusion sheet 1 in the urine treatment material X according to the present embodiment, similar to Example 2 described later.

[0054] Here, a test conducted to confirm the ammonia neutralization performance of the urine treatment material X according to the present embodiment will be described. The urine treatment material X used in this test is a type of urine treatment material X in which a recess 2 is provided on the surface of the urine diffusion sheet 1 shown in FIG. 1.

[0055] In this test, the urine treatment material X was placed in a sealed space (a water tank with a width of 30 cm, a depth of 60 cm, and a height of 36 cm with the upper opening closed by a lid) in a state where it was attached to the upper surface of a urine absorption sheet 30 described later with double-sided tape. Ammonia (NH 3 ) with a concentration of 5000 ppm was dropped 70 ml at a time onto the urine treatment material X to diffuse and pass through for neutralization treatment (the neutralized urine 60 is absorbed by the urine absorption sheet 30). After dropping urine 60 every day for 7 days, the ammonia concentration in the sealed space was measured with a gas detection device.

[0056] FIG. 8 is a table showing the results of the above test. The ammonia concentration in the air in the sealed space was extremely low at 1 ppm even on the 7th day. This is a value such that when the air in the sealed space is introduced (diluted) into the air in the indoor space, no ammonia odor can be detected even by smelling with the nose.

[0057] From the above test, it was confirmed that the urine 60 introduced into the urine treatment material X immediately diffused and passed through without forming a urine pool (confirmed visually), could prevent the generation of ammonia odor as much as possible, and could suppress the harm to the surrounding environment caused by the ammonia odor.

[0058] The usage state of the urine treatment material X according to this embodiment having the above configuration will be described.

[0059] FIG. 9 shows an example of use in which the urine treatment material X is attached and fixed to the upper surface of the urine absorption sheet 30 with double-sided tape.

[0060] This urine absorption sheet 30 is a product in which a urine absorption member 30b (a mixture of cotton-like pulp and a polymer absorption member) is housed in a water-permeable bag body 30a (a bag body formed by hot-melt bonding the peripheral portions of a pair of polymerized hydrophilic polyolefin nonwoven fabrics).

[0061] FIG. 10 shows a configuration in which the urine treatment material X is housed in the bag body 30a of the urine absorption sheet 30 described above (when it is housed in the urine absorption sheet 30 and commercialized), and the urine treatment material X is disposed above the urine absorption member 30b.

[0062] As described above, the urine treatment material X according to this embodiment is arranged on the urine absorption sheet 30 and disposed in the urine receiving portion 50a of the pet toilet 50.

[0063] In this state, when the pet C urinates urine 60, the urine 60 introduced from the upper surface side is absorbed by the urine diffusion sheet 1 and diffuses while passing to the lower surface side. At this time, ammonia in the urine 60 is neutralized in the ammonia neutralization treatment portion 3 provided in the urine diffusion sheet 1. The urine 60 introduced from the upper surface side is subjected to ammonia neutralization treatment in the ammonia neutralization treatment portion 3, and quickly passes to the lower surface side from the thin bottom wall portion 2b (or side wall portion 2a) obtained by providing the concave portion 2.

[0064] Also, as described above, by making the state in which the urine treatment material X is attached and fixed to the upper surface of the urine absorption sheet 30 (the state in FIG. 9) or the state in which it is housed in the urine absorption sheet 30 (the state in FIG. 10), it is possible to prevent partial swelling of the polymer absorption member due to the urine 60, and the entire urine absorption sheet 30 (bag body 30a) becomes a flat swelling.

[0065] Since this embodiment is configured as described above, in the conventional example described above, the layered ammonia neutralization treatment part (spray glue) provided on the surface of the urine diffusion sheet 1 slows down the diffusion and passage of the urine 60, causing urine accumulation and preventing good neutralization treatment. In this regard, however, this embodiment allows the introduced urine 60 to pass through while swiftly diffusing it, and furthermore, since the urine diffusion sheet 1 is configured by impregnating and drying an ammonia neutralizer solution 3' containing an ammonia neutralizer that neutralizes ammonia, the ammonia neutralizer is uniformly dispersed within the urine diffusion sheet 1, and the ammonia neutralization treatment ability becomes uniform throughout the entire urine diffusion sheet 1, thereby demonstrating good ammonia neutralization treatment ability.

[0066] In addition, in this embodiment, the urine diffusion sheet 1 is provided by directing the ammonia neutralizing solution 3' from the roller body 12c rolling on the surface of the sheet base material 1', so that the urine treatment material X having the above-mentioned functional effects can be obtained easily and reliably.

[0067] In addition, in this embodiment, the ammonia neutralizing solution 3' is a mixture of citric acid and water, so it can be impregnated well into the urine diffusion sheet 1 (sheet base material 1'), and can easily impart good ammonia neutralization treatment function.

[0068] <Example 2> A second specific embodiment of the present invention will be described with reference to the drawings.

[0069] In this embodiment, in addition to the configuration of the above-mentioned embodiment 1, a urine treatment material Y is provided in which a cover sheet 4 is laminated on the surface of the urine diffusion sheet 1 on which the recesses 2 are provided, as shown in Figure 11, which absorbs and diffuses urine 60 introduced from the upper side while allowing it to pass to the lower side.

[0070] Specifically, the entire area of ​​the urine diffusion sheet 1 is provided with an ammonia neutralization treatment section 3 (shown in gray in the figure) which is constructed by impregnating and drying an ammonia neutralizer solution 3' (shown in gray in the figure) containing an ammonia neutralizer that neutralizes ammonia.

[0071] In this embodiment, an ammonia neutralization treatment section 3 is provided in the urine diffusion sheet 1 by an ammonia neutralization treatment section forming apparatus H2 described later.

[0072] As shown in FIG. 12, this ammonia neutralization treatment section forming apparatus H2 includes a sheet feeding section 20 provided on the upstream side of the apparatus for feeding out a long and wound urine diffusion sheet 1 (sheet base material 1'), a sheet recovery section 21 provided on the downstream side of the apparatus for winding and recovering the urine diffusion sheet 1, and a liquid tank section 22, a coating sheet supply section 24, and a liquid drying section 23 provided between the sheet feeding section 20 and the sheet recovery section 21.

[0073] The liquid tank section 22 is configured by providing a support roller 22b in a tank member 22a for storing the ammonia neutralization material solution 3' to support the urine diffusion sheet 1 (sheet base material 1') passing through the tank member 22a from above.

[0074] The coating sheet supply section 24 is provided above the urine diffusion sheet 1 (sheet base material 1') conveyed between the liquid tank section 22 and the drying section 23, and is configured to supply and laminate the coating sheet 4 on the surface of the urine diffusion sheet 1 (sheet base material 1') conveyed to the liquid drying section 23. In this embodiment, the same material as the above-described urine diffusion sheet 1 (sheet base material 1') is adopted as the coating sheet 4.

[0075] The liquid drying section 23 is configured to derive warm air to the conveyed urine diffusion sheet 1 (sheet base material 1') to dry the ammonia neutralization material solution 3' impregnated in the urine diffusion sheet 1.

[0076] Reference numeral 25 is a pressure roller, and 26 is a tension roller.

[0077] Therefore, in the ammonia neutralization treatment unit forming apparatus H2, the urine diffusion sheet 1 (sheet base material 1') is fed out from the sheet feeding unit 20. The urine diffusion sheet 1 (sheet base material 1') passes through the liquid tank unit 22 and is immersed in the ammonia neutralizing material solution 3', and the ammonia neutralizing material solution 3' is impregnated into the inside of the urine diffusion sheet 1 (sheet base material 1'). Subsequently, the coating sheet 4 is laminated on the urine diffusion sheet 1 (sheet base material 1') impregnated with the ammonia neutralizing material solution 3' and is pressure-rolled by the pressure roller 25. Subsequently, it passes through the drying unit 23 and is dried, and the dried urine diffusion sheet 1 is collected by the sheet collection unit 21. Thereafter, the long urine diffusion sheet 1 (with the coating sheet 4 laminated) collected by the sheet collection unit 21 is cut into a predetermined length (rectangle) to become the urine treatment material Y, and a fixing double-sided tape (not shown) is provided at the lower peripheral edge of each of the cut urine treatment materials Y.

[0078] This urine treatment material Y, similar to the aforementioned urine treatment material X, can be arranged on the upper surface of the urine absorption sheet 30 or inside the urine absorption sheet 30.

[0079] Since this embodiment is configured as described above, a coating sheet 4 that absorbs and diffuses the urine 60 introduced from the upper surface side and allows it to pass to the lower surface side is laminated on the surface of the urine diffusion sheet 1. Therefore, the introduced urine 60 is diffused better and the ammonia neutralization treatment is performed well.

[0080] Also, in this embodiment, the sheet base material 1' conveyed from the sheet feeding unit 20 to the sheet collection unit 21 is immersed and passed through the ammonia neutralizing material solution 3' in the liquid tank unit 22 provided between the sheet feeding unit 20 and the sheet collection unit 21, and the ammonia neutralizing material solution 3' is impregnated into the sheet base material 1'. Therefore, the urine treatment material Y having the above-described effects can be obtained simply and reliably.

[0081] The rest is the same as in the first embodiment.

[0082] Note that the present invention is not limited to the first and second embodiments, and the specific configurations of the respective components can be designed as appropriate.
