Description

  The present invention relates to an animal toilet such as a pet animal.

  Recently, breeding of pets and the like indoors has become very popular, and animal toilets for effectively treating excreta have been proposed. For example, as shown in FIG. 5, the upper part of the toilet 10 ′ is partitioned vertically by a porous member 15 ′, and sand 31 ′ having a water repellent function is provided on the upper surface of the porous member 15 ′. There is a pet manure processing floor T ′ in which a granular urine absorbing member 32 ′ is laid on the floor surface 13 ′ (Reference Document 1).

JP-A-7-67489

However, in the conventional animal toilet T ′, since the sand 31 ′ provided on the upper surface of the porous member 15 ′ has a water repellent function, it merely serves to transmit urine downward, Only the lower urine-absorbing member 32 ′ absorbs urination. Therefore, the problem that the bad smell by urination etc. cannot be prevented effectively existed.
Further, in the conventional animal toilet T ′, if urination is performed locally, only a part of the urine sucking member 32 ′ is used and the processing capacity is lowered. Therefore, the urine sucking member 32 ′ must be frequently replaced. There was a problem of not becoming.

  The present invention has been made to solve the above-described problems, can reliably prevent malodor due to urination and the like, and can effectively perform urination even when there is a bias in the urination location. The object is to provide an animal toilet that can be used.

In order to solve the above-described problems, an animal toilet of the present invention includes a urine container having a lid and a bottomed hollow box shape, and a plurality of treatment body storage containers, and the lid portion is non-water-absorbing. And a plurality of urine outlets are formed in the lid portion, and each of the urine outlets is formed with a plurality of urine outlets. A plurality of urinary tracts communicating with each other, and any of the urinary tracts and any of the processing body storage containers communicate with each other, and each of the urinary tracts includes the first granular processing body. Is characterized in that a urine dropping hole is formed which can be retained in each urinary tract .

Here, “communication” means a state where the space is continuous and water can be passed (water can be introduced).
Further, the lid portion and the urinary tract may be separate bodies that can be attached and detached, or may be integrally molded.
In addition, it is preferable that at least two of the urination port, the urinary tract, or the processing body container are the same because urination can be processed with a simple structure.

  The animal toilet of the present invention has a lid and bottomed hollow box shape, and can hold urine in the inside thereof, so that odor can be effectively prevented. Further, as will be described later, it is possible to provide a structure capable of processing urination by providing a plurality of granular urination processing bodies outside or inside thereof.

  In addition, according to the present invention, the apparatus includes a plurality of processing body containers, a plurality of urination ports formed in the lid, and a plurality of urinary tracts communicating with the respective urination ports. The urinary tract and the one of the treatment body storage containers communicate with each other. Therefore, even when urination is performed locally, urination is guided by the urinary tract, and urination is dispersed and processed in a predetermined area, thereby preventing urination from concentrating on a certain location. Can effectively treat urination.

  Further, in the animal toilet, each of the treatment container containers may be integrally formed with the urine container, but is disposed in a separate container and the container is taken out from the urine container. If it is formed so that it can be freely configured and the processing body container is configured to be replaceable, it is preferable because cleaning work and the like can be easily performed.

  Here, the container can be easily taken out from the urine container, and can easily be removed when a second granular processing body (described later, also in the case of a sheet-like liquid-absorbing processing material) is placed therein. As long as the structure can be replaced, the shape of the tray material, box, etc. is not limited.

  Further, in the animal toilet, the urine container has an opening, and the container is formed so as to be removable from the opening of the urine container, and the periphery of the opening. If the part is provided with an intervention member for maintaining airtightness, it is possible to more effectively prevent the odor emitted from urination from being released to the outside of the urination container. Is preferred.

  Here, the intervention member may be any material and form that can close the gap of the opening during normal use without hindering the removal of the container or equipment, etc. For example, a seal member, a material made of synthetic resin, etc., and a deformable curtain member can be used.

  Further, in the animal toilet, a plurality of first granular treatment bodies including a non-water-absorbing adsorbent material and molded into a granular shape are laid on the upper surface of the lid portion, and the granular core portion and the above-described A plurality of second granular treatment bodies having a multi-layer structure having a covering layer portion covering the core portion, wherein the covering layer portion includes an adhesive material and is formed into a lump by absorbing urine However, it can be accommodated in each said processing body storage container.

According to the present invention, urination can be processed using a plurality of granular processing bodies having different properties, so that malodor can be effectively prevented.
That is, according to the animal toilet of the present invention, the first granular processing body containing the adsorbing material has a deodorizing performance due to the adsorbing function, so that a deodorizing effect can be achieved.
Further, the second granular processing body has a multilayer structure having a granular core part and a coating layer part covering the core part, and the coating layer part contains an adhesive material and absorbs urine to form a lump. Therefore, the urination processed by the first granular processing body can be absorbed and processed in a lump shape.

  In addition, since a plurality of processing body storage containers are provided and each of the second granular processing bodies is stored, if the processing body storage container is replaceable, the use state is partially biased. Even when it is necessary to replace only the second granular processing body, it is possible to replace only the second granular processing body accommodated only in that portion, so that the replacement cost can be suppressed. In addition, it is possible to easily perform care after urination such as cleaning.

  Further, in the animal toilet, a plurality of first granular treatment bodies including a non-water-absorbing adsorbent material and molded into a granular shape are laid on the upper surface of the lid portion, and a plurality of sheet-like absorbent materials are disposed. A liquid processing body may be provided, and the sheet-like liquid absorption processing body may be accommodated in each of the processing body storage containers.

  An embodiment for carrying out the present invention (hereinafter referred to as “embodiment”) will be described in detail with reference to the drawings. In the following description, the same members and the like are denoted by the same reference numerals, and redundant description is omitted.

<First Embodiment>
As shown in FIGS. 1 and 2, the animal toilet T1 (first embodiment) of the present invention includes a urine container 10, a plurality of first granular treatment bodies 31 filled in the urine container 10, and The second granular processing body 32 is configured.

(1) Urination container 10
The urine container 10 is formed in a rectangular parallelepiped box shape using synthetic resin as a raw material. This urine container 10 is formed of a hollow container body 11 having a bottom part 11a and a peripheral wall part 11b, and a lid part 15 for closing the upper surface of the container body 11, and excluding an opening part to be described later. The water-tightness and air-tightness are maintained.

The lid portion 15 is formed in a shape that covers the upper surface of the container body 11 and is fitted so as to be easily removable from the container body 11. In addition, the lid portion 15 is formed with recesses 15a so as to have a predetermined depth for laying the first granular processed body 31, and six circular urination ports 15b are arranged in two rows in the short direction. Perforations are made at predetermined intervals so that there are three rows in the longitudinal direction.
The lid 15 has a predetermined endurance performance in order to place a pet animal on the upper part and urinate. In addition, the lid portion 15 is formed with an appropriate slope so that urination is guided to the urination port 15b.

On the lower surface of the lid 15, six urinary tracts 21 having a quadrangular pyramid shape whose cross-sectional area is gradually reduced from the upper end toward the lower end project downward so as to communicate with each urination port 15 b. Are integrally formed. The urinary tract 21 has a cross-sectional area on the upper surface that is substantially the same area as the second treatment body containing cup 22 described later, and the center line (perpendicular line) of the lower end (lower surface) coincides with the center line of the urination port 15b It is provided to do. The urinary tract 21 is provided to receive urine dripped from the urination port 15b and guide it to the second processing body storage cup 22 (processing body storage container), and the inside thereof is hollow.
In addition, a plurality of urine dropping holes 21a are formed in the lower end portion whose area is narrowed in plan view, and urine drops from the portion. The urine dropping hole 21 a needs to have a shape and a number that allow only the urine to pass therethrough and keep the first granular processing body 31 in the urinary channel 21.

  A large amount of the first granular processing body 31 is filled in the concave portion 15 a of the lid portion 15, the inside of the urination port 15 b and the urinary tract 21. As a result, the urine dropping hole 21a is closed so as not to come into direct contact with the outside air, so that the odor transmitted from the second processing body accommodation cup 22 is not emitted to the outside of the urine container 10.

On one side of the container body 11 in the short side direction, a side opening 11c (opening) for pulling out and inserting a storage tray 13 (separate container) is formed at a position below the intermediate height. ing. The side opening 11c has a shape in which the end closes the side opening 11c, has a predetermined height dimension so as to be fitted in the lower space of the container body 11, and the upper part opens. The storage tray 13 which is a rectangular parallelepiped is provided so as to be removable (movable).
A plurality of curtain members 16 (intervening members) made of vinyl resin, rubber, or the like formed in a rectangular thin plate shape to improve airtightness are deformed on the peripheral portion of the mouth shape of the side opening 11c. It is provided freely. When the storage tray 13 is fitted in the container main body 11, the curtain material 16 is stored in the container main body 11 by being pressed and deformed, and the curtain 16 is formed between the storage tray 13 and the side opening 11c. While playing the role of closing the gap, when the storage tray 13 is pulled out, it returns to a downward, lateral or upward shape.

The storage tray 13 has an open top surface and a hollow rectangular parallelepiped-shaped second processing body storage cup 22 having a bottom and a wall so that there are two rows in the lateral direction and three rows in the longitudinal direction. Are provided so that there is almost no gap between the adjacent cups. These 2nd process body accommodation cups 22 are cups made from synthetic resin, such as paper property or a polyethylene terephthalate by which the polyethylene lamination process is performed inside.
In addition, the lower surface of the urinary tract 21 is disposed so as to be positioned substantially at the center of the opening on the upper surface of the second processing body accommodation cup 22.

  The second processing body accommodation cup 22 is filled with a plurality of second granular processing bodies 32 which will be described later. Since the second processing body storage cup 22 is not fixed to the storage tray 13 but is placed so that it can be removed, the storage tray 13 is removed from the urine container main body 11, and a desired container is obtained. By taking up the second processing body accommodation cup 22, the filled second granular processing body 32 can be easily exchanged.

  The reference numeral 13 a is a handle for gripping the storage tray 13 when taking it out or inserting it into the container body 11.

  With the above configuration, in the state in which the storage tray 13 is fitted inside the container body 11, the side opening 11c is closed, integrated with the bottom 11a and the peripheral wall 11b, and the predetermined watertightness and airtightness are maintained, and odor Has a structure that hardly leaks to the outside.

(2) First granular processing body 31
The 1st granular processing body 31 uses coffee extraction residue and an adhesive as main constituent materials, and those constituent materials are kneaded. The first granular processing body 31 is a non-water-absorbing granular processing body that does not substantially absorb moisture. The shape is not particularly limited as long as it is formed in the shape of a small lump and does not need to be a perfect sphere or the like, and may be any shape such as a columnar body (elongated shape) or a flat shape.
The first granular processed body 31 can be manufactured by a known granulation method such as extrusion granulation, but has a higher hardness than a general granular body so as not to absorb water. Need to be done.

The coffee extraction residue is an extraction residue discharged when roasted coffee beans are extracted from roasted coffee beans when coffee beverages such as canned coffee and instant coffee are produced from roasted coffee beans. . This coffee extract residue is an extract of the coffee extract, but since the coffee component remains, aroma is emitted and when water is given from the outside, a brown coffee extract is generated. It has become.
The coffee extraction residue is preferably 80% by weight to 99% by weight with respect to the total weight of the granular processed body in order to effectively exhibit the odor absorbing action and the aroma action.

  Moreover, an adhesive agent is used in order to shape | mold the 1st granular process body 31, and a well-known material can be used for it. However, since the first granular processed body 31 has a non-water-absorbing property, it is preferable that the adhesive has a property of not having water absorption. In the case where a large amount of adhesive is not used, a water-absorbing adhesive that is finely pulverized (the water-absorbing performance is reduced by fine pulverization) can also be used.

(3) Second granular processing body 32
The 2nd granular processing object 32 has the multilayer structure formed from a core part and the coating layer part which coat | covers the surface of this core part, and those constituent materials are knead | mixed. The second granular processed body 32 is an absorption type granular processed body that absorbs moisture.
In addition, this 2nd granular process body 32 can also be manufactured by well-known granulation methods, such as extrusion granulation.

[Core]
As long as the core has water absorption performance, there are no particular restrictions on materials other than coffee extraction residue (coffee extraction residue is an essential constituent material), inorganic materials such as bentonite and zeolite, pulp for papermaking, kenaf, It can be manufactured by kneading these constituent materials using a single substance or a mixture of organic waste materials such as pulp sludge as a raw material, and using these materials mixed with a water-absorbing resin as a base material.

[Coating layer]
The main purpose of the coating layer portion is to cause the second granular treatment bodies 32 wetted with urine or the like to adhere to each other at the time of use to form a lump and wrap urine from the surroundings. As an example of the constituent material of such a covering layer portion, a water-absorbing resin, an adhesive material (adhesive material) or a mixture of both materials and a mixture of paper powder and kneading these can be manufactured. Is preferred.
Examples of the adhesive material include a superabsorbent resin such as glue and sodium polyacrylate. Examples of the paste functioning as an adhesive include potato starch, wheat starch, sweet potato starch, corn starch, tapioca starch, rice starch, dextrin, starches such as starches converted to alpha (α), acrylamide, PVA, carboxy Methylcellulose or sodium alginate can be used, or a combination of two or more of these can be used. Other adhesive materials include super absorbent resins, vinyl esters, bentonite, pullulan, casein or gelatin, which are used alone or in combination of two or more. . In addition, examples of the alcohol-soluble adhesive material include hydroxyethyl cellulose (HEC), hydroxypropyl cellulose (HPC), and polyvinyl pyrrolidone (PVP). The above can be mixed and used.

[Effects]
Subsequently, a method of using the animal toilet T1 of the present invention will be described.
First, a predetermined amount of the first granular processing body 31 and the second granular processing body 32 are filled in the concave portion 15a of the lid portion 15 and the second processing body accommodation cups 22, respectively. At this time, the aroma of coffee emitted from the first granular processing body 31 is emitted toward the indoor space.

  Subsequently, the pet animal is urinated from the upper side of the lid 15. Then, urination passes through and around each of the first granular processed bodies 31 and drops downward, and in the process, odors such as ammonia odor are adsorbed due to the adsorption action of the coffee extraction residue and the like. It drops downward while passing through the urination port 15b and the urinary tract 21.

  Then, it passes through the urine dropping hole 21 a and reaches the second granular processing body 32 filled in the second processing body accommodation cup 22. In the second granular processing body 32, the coating layer portion absorbs urination, and the coating layer portion of the adjacent second granular processing body 32 adheres by urination to form a mass 33, and wraps excrement from its surroundings. Will be played. Therefore, the urination part can be easily confirmed.

  When the lump 33 of the second granular processing body 32 increases, the storage tray 13 is pulled out, and only the second granular processing body 32 that has become the lump 33 is taken out and discarded, or for each second processing body storage cup 22. Then, the second processing body storage cup 22 filled with a new second granular processing body 32 is replaced (see FIG. 3). Then, the new second granular processing body 32 is replenished, and the storage tray 13 is fitted into the container body 11.

  In addition, the first granular processing body 31 can be used for a long period of time as compared with the second granular processing body 32. However, after the predetermined period has elapsed, the lid 15 can be removed and replaced, or the urination port The first granular processed body 31 after use is taken out from 15b, the inside thereof is washed, and a new first granular processed body 31 is filled and used. In some cases, the integrally formed lid 15 can be replaced.

As described above, according to the animal toilet T1 of the present invention, urination can be effectively performed by using two types of granular processed bodies having different properties.
That is, since the 1st granular process body 31 containing a coffee extraction residue has a deodorizing performance, it can prevent the bad smell which urination has, and since there is an aroma effect by the aroma of the coffee which a coffee extraction residue emits, there is no special consideration. The effect as a fragrance can be exhibited. Since this first granular processed body 31 hardly absorbs urine and only permeates it, it does not disintegrate in a single use and does not cause a significant change in its properties and appearance by drying, It can be used repeatedly over several times.
In addition, although the 1st granular processing body 31 will be gradually collapse | disintegrated by using repeatedly, since the contact area with urination increases so that it collapses and becomes granular, the outstanding deodorizing effect is exhibited. Will be.

  Moreover, since the 2nd granular process body 32 has a multilayer structure and becomes the lump 33 by absorbing water, it can recognize a use part easily and only the part which became the lump 33 is easy. Can be removed.

  In addition, a plurality (six in this embodiment) of second processing body accommodation cups 22 are provided, and a plurality of urination ports 15b formed in the lid portion 15 and a plurality of guides communicating with the respective urination ports 15b. The urinary tract 21 is provided, and the urinary tract 21 and the second processing body accommodation cup 22 communicate with each other. Therefore, even when urination is locally performed, urination is guided by the predetermined urinary tract 21, and urination is dispersed in a predetermined region (a region of 1/6 of the plane area of the container body 11). Since it is processed, it is possible to prevent urination from concentrating on a certain place and to effectively process urination.

  In addition, since a plurality of second treatment body accommodation cups 22 are provided and the second granular treatment bodies 32 are accommodated therein, only some of the second granular treatment bodies 32 are used due to reasons such as uneven usage. Even if it is necessary to replace the second granular processing body 32, it is possible to replace only the second granular processing body 32 accommodated only in that portion, so that the replacement cost can be reduced and cleaning is performed. Therefore, it is possible to easily perform maintenance after urination.

Moreover, since the 2nd process body accommodation cup 22 is mounted so that extraction is possible to the accommodation tray 13, it is easy to remove the 2nd granular process body 21 only by pulling out the said accommodation tray 13 from the container main body 11. FIG. Can be replaced.
In addition, since the curtain material 16 for maintaining airtightness is provided at the peripheral edge of the side opening 11c, the odor emitted from urination when the storage tray 13 is stored in the urine container 10 Can be effectively prevented from being released to the outside of the urination container 10.

  Moreover, since the urine container 10 has the cover part 15 and the bottom face 11a part, and is a hollow box type shape and is provided with predetermined airtightness and watertightness, it can prevent a malodor from spreading outside. it can.

  In addition, since the urination ports 15b, the urinary tracts 21 and the second processing body accommodation cups 22 of the lid portion 15 are the same number and are arranged in parallel in the height direction, urination can be performed from the urination port 15b with a simple structure. The urinary tract 21 and the second processing body accommodation cup 22 can be guided.

Second Embodiment
As shown in FIG. 4, the animal toilet T2 (second embodiment) of the present invention includes a urine container 10, a plurality of first granular treatment bodies 31 filled in the urine container 10, and a plurality of sheets ( In the present embodiment, the urine absorbing sheet 42 (sheet-like liquid absorption treatment material) is composed of six sheets.

The animal toilet T2 of the present embodiment is greatly different in that a urine absorbing sheet 42 for absorbing urine is laid instead of the second treatment body accommodation cup 22 in the animal toilet T1 of the first embodiment. .
In order to facilitate the laying of the urine absorbing sheet 42 on the accommodation tray 13 ′, partition members 14 are provided in the vertical direction and the horizontal direction so as to have substantially the same shape as the urine absorbing sheet. Each urine absorbing sheet 42 is laid in each section of the storage tray 13 ′ so that the lower part of the urinary tract 21 is located almost at the center. This urine absorbing sheet 42 can also be easily replaced by pulling out the storage tray 13 ′ to the outside of the container body 11 as in the case of the second water absorption treatment material storage cup 22 in the animal toilet T 1 of the first embodiment. It is possible.

  The urination absorbing sheet 42 may be of any type as long as it can absorb urine. In other words, the urine absorbing sheet 42 may be formed by forming a liquid-absorbing material into a sheet having a predetermined thickness, and may be either a single layer or a multilayer structure in which a water-impermeable sheet material is provided in the lower layer. May be.

  When the animal toilet T2 is used, the urination of the companion animal is processed by the first granular processing body 31, and the urine absorbing sheet 42 is passed through the urine outlet 15b of the lid 15 and the urine dropping hole 21a of the urinary tract 21. The urine absorbing sheet 42 is absorbed and processed until it reaches the absorption limit amount. When the urine absorbing sheet 42 reaches the absorption limit amount, as in the case of the animal toilet T1 of the first embodiment, the accommodation tray 13 ′ is pulled out and only the desired urine absorbing sheet 42 is replaced. Can do.

As described above, even when the animal toilet T2 of the present embodiment is used, substantially the same effects as the animal toilet T1 of the first embodiment can be obtained.
Moreover, since the exchange of the urine absorbing sheet 42 is easy as compared with the case where the second granular processing body 32 is used, further cleanup after use can be easily performed.

As mentioned above, although an example about a suitable embodiment was explained about the present invention, the present invention is not restricted to the embodiment concerned, and a design change is possible suitably in the range which does not deviate from the meaning of the present invention.
In particular, the shape, material, etc. of the urination container are not limited, and may be a structure with a lid, a bottom, and a peripheral wall, as long as predetermined confidentiality and water tightness are maintained. The position and shape of the urination port of the lid are not limited as long as the urination opening of the lid is open so that the animal can urinate.

  Moreover, there is no restriction | limiting in the form of a cover part, a urinary tract, a 2nd process body storage container, etc., and the form (including the presence or absence of a partition member) of a container, The urination was permeate | transmitted to the 1st granular process body. Any structure may be used as long as it can be guided to the second processing body storage container later.

Further, in this embodiment, the case where the number of urination ports, urinary tracts, and second processing body storage containers in the lid is six has been described as an example. However, the urination port, urinary tract, and second processing body storage containers are described. There is no limit to the number of items, and it is appropriately determined depending on the size of the animal toilet.
Moreover, there is no restriction | limiting also regarding the shape and number of the urination dropping hole of a urinary tract, and it may be formed in slit shape or mesh shape.
Moreover, if the urination container is formed of a transparent material, it is particularly preferable because the inside situation can be recognized.

  Furthermore, not the coffee extraction residue but various tea husks such as Japanese tea, black tea, oolong tea, or wood powder can be used for the first granular processed body. However, when the tea husk is used, it is preferable to use the same kind of tea husk as the tea husk used for the first granular crushed material instead of the coffee extraction residue as the constituent material of the second granular crushed material. .
