The excrement disposal material described in the document includes a plurality of granular bodies for absorbing and treating excrement. These granules are packed together in one packaging bag and shipped.

JP 2010-158253 A

Storing a plurality of granules in the packaging bag in this way contributes to the convenience of transportation and storage of the excreta disposal material. However, one packaging bag generally contains a relatively large volume (about 5 to 10 liters) of granules. Therefore, conventional excreta disposal materials have a problem of high transportation and storage costs.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an excrement disposal material suitable for reducing transportation and storage costs, and a method for producing the same.

The excreta disposal material according to the present invention comprises a plurality of granules for treating excrement, and each granule has a compressive restoring force.

This excrement disposal material is provided with a plurality of granular bodies. Each grain has a compression restoring force. Here, the compression restoring force is the ability to be compressed to 50% or less of the original volume when subjected to an external force, and to recover naturally to 80% or more of the original volume when the external force is removed. Say. When each granular material has a compressive restoring force in this manner, each granular material can be accommodated in the packaging bag in a compressed state. As a result, the volume of the whole excrement disposal material can be reduced. This leads to a reduction in transportation and storage costs for the excreta disposal materials.

Further, the method for producing an excreta disposal material according to the present invention includes a granule forming step of forming a plurality of granules for treating excreta, and in the granule forming step, each of the above-described granules having compression restoring force is provided. It is characterized by forming granules.

In this manufacturing method, a plurality of granules are formed. Each grain has a compression restoring force. When each granular material has a compressive restoring force in this manner, each granular material can be accommodated in the packaging bag in a compressed state. As a result, the volume of the whole excrement disposal material can be reduced. This leads to a reduction in transportation and storage costs for the excreta disposal material.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and overlapping descriptions are omitted.

FIG. 1 is a plan view showing one embodiment of the excrement disposal material according to the present invention. The excrement disposal material 1 is an excrement disposal material used for disposal of animal or human excrement (particularly urine), and comprises a plurality of granular bodies 10 and a packaging bag 20 . The granules 10 are granules for treating excrement. In the present embodiment, the granular material 10 treats the excrement by absorbing it.

FIG. 2 is a schematic diagram showing the granular material 10. As shown in FIG. Each granular material 10 is granular. Such granular shapes include, for example, spheres, cylinders or ellipsoids. The particle size of each granular material 10 is, for example, 5 mm or more and 20 mm or less. Here, the particle size of each particle 10 is defined as the diameter of the smallest sphere that can contain the particle 10 .

Each grain 10 has compression restoring force. As described above, compression restoring force is the ability to compress to 50% or less of the original volume when subjected to an external force, and to recover naturally to 80% or more of the original volume when the external force is removed. Say. The “volume” referred to here is the volume including the voids of each granular body 10 . The voids include both open pores (voids that communicate with the outside of the granular body 10) and closed pores (voids that do not communicate with the exterior of the granular body 10). Each granular body 10 is preferably compressible to 30% or less of its original volume, and more preferably compressible to 20% or less of its original volume, when subjected to an external force. In addition, when the external force is removed, each granular body 10 preferably recovers naturally to 90% or more of its original volume, more preferably recovers naturally to 99% or more of its original volume.

Whether or not the granular material 10 has compression restoring force can be determined by the following test. First, as shown in FIG. 3, a cylindrical container 90 having an inner diameter of about 10 to 12 cm and a height of about 12 to 15 cm, and a disk-shaped lid 92 having a thickness of about 0.5 to 2 cm are prepared. The lid 92 has a diameter one size (about 1 to 3 mm) smaller than the inner diameter of the container 90 so that it can be smoothly moved up and down inside the container 90 while maintaining a substantially horizontal state. The material of container 90 and lid 92 is, for example, glass or plastic. Next, as shown in FIG. 4, a plurality of granules 10 (samples) are put into a container 90 to a height of about 10 cm. In this state, the height h of the sample (the distance from the bottom surface of the container 90 to the top end of the sample) is measured, and the value is defined as h1.

Next, as shown in FIG. 5, the lid 92 is placed on the sample and the lid 92 is manually pushed down until the height h of the sample reaches h2. where h2 is equal to 1/2 of h1. At this time, the fact that the lid 92 can be pushed down until the height h reaches h2 without collapsing the granules 10 means that each granule 10 can be "compressed to 50% or less of its original volume when subjected to an external force." means that Subsequently, after maintaining the state where the height h is h2 for 30 seconds, the lid 92 is removed and the apparatus waits for 30 seconds. After that, as shown in FIG. 6, the height h of the sample is measured and its value is set to h3. If h3 is 80% or more of h1, it can be said that the granular material 10 has compression restoring force. At this time, that h3 is 80% or more of h1 means that each grain 10 "recovers naturally to 80% or more of its original volume when the external force is removed."

Each granular body 10 is mainly made of paper. Here, the main material refers to one or more materials constituting each granular body 10 and having the largest weight ratio in the granular body 10 . Paper refers to materials mainly composed of pulp. Examples of paper include ordinary paper, paper towels, classified vinyl chloride wallpaper (paper obtained by classifying vinyl chloride wallpaper), fluff pulp, paper sludge, pulp sludge, and the like.

Each granule 10 may be made of paper only, or may be made of paper and another material. Other materials are, for example, adhesive materials. Adhesive materials include, for example, water-absorbing polymers, starch, CMC (carboxymethylcellulose), PVA (polyvinyl alcohol), or dextrin. That is, each granular body 10 may or may not contain a water absorbing polymer. The same applies to adhesive materials other than water-absorbing polymers.

Returning to FIG. 1 , a plurality of granules 10 are accommodated in packaging bag 20 . The inside of the packaging bag 20 is in a vacuum state. Each granular material 10 is accommodated in the packaging bag 20 in a compressed state. Each granule 10 is compressed to 50% or less of its original volume within the packaging bag 20 . Each granular material 10 is preferably compressed to 30% or less of its original volume within the packaging bag 20, and more preferably compressed to 20% or less. In this embodiment, the packaging bag 20 is made up of two sheets whose peripheral edges are bonded together. The packaging bag 20 is hermetically sealed by bonding the peripheral edges in this manner. This packaging bag 20 has flexibility. As a material of the packaging bag 20, for example, plastic such as polyethylene can be used.

Next, an example of a method for manufacturing the excrement disposal material 1 will be described as an embodiment of the method for manufacturing the excrement disposal material according to the present invention. This manufacturing method includes a granule forming step and a granule accommodation step.

The granule forming step is a step of forming a plurality of granules 10 . In this step, for example, each granule 10 is formed by rounding the constituent material (material forming the granule 10) into granules. At this time, an adhesive material may be used as a binder. Prior to granulation, the constituent materials are subjected to pretreatment such as pulverization, kneading, adding water, etc., as required. However, compression granulation or extrusion granulation is not performed because it becomes difficult to impart compression restoring force to the granules 10 when too much pressure is applied when the constituent materials are granulated.

The granule accommodation step is a step of accommodating the plurality of granules 10 formed in the granule formation step in the packaging bag 20 . In this process, a filling machine or the like is used to put a predetermined amount (for example, 7 liters) of granules 10 into a packaging bag 20 whose upper end is open. In this step, each granular material 10 accommodated in the packaging bag 20 is compressed. For example, each granular material 10 can be compressed by evacuating the inside of the packaging bag 20 containing the multiple granular materials 10 . Such vacuum processing can be performed by, for example, sucking the air inside the packaging bag 20 using a suction nozzle or the like. After that, the upper end of the packaging bag 20 is closed to seal the packaging bag 20 so that the vacuum state is maintained. As described above, the excrement disposal material 1 is obtained.

Effects of the present embodiment will be described. In this embodiment, a plurality of granules 10 are formed. Each grain 10 has compression restoring force. When each granular material 10 has a compressive restoring force in this manner, each granular material 10 can be accommodated in the packaging bag 20 in a compressed state. As a result, the volume of the whole excrement disposal material 1 can be reduced. This leads to a reduction in transportation and storage costs of the excrement disposal material 1. Therefore, an excrement disposal material 1 suitable for reducing transportation and storage costs and a manufacturing method thereof have been realized.

Since each granular material 10 has a compressive restoring force, even if it is stored in the packaging bag 20 in a compressed state, it expands after the packaging bag 20 is opened and returns to its original volume (the original volume stored in the packaging bag 20). It can be recovered spontaneously to the volume immediately before it was removed) or to a volume close to it (specifically, 80% or more of the original volume).

As the volume of the excrement disposal material 1 is reduced, the effect of reducing the transportation and storage costs of the excrement disposal material 1 can be enhanced. From this point of view, each granular body 10 is preferably compressible to 30% or less of its original volume, and more preferably compressible to 20% or less of its original volume.

Each granular body 10 is mainly made of paper. Paper is a material that is excellent in water absorption, safety, and low cost. Therefore, using such a material as the main material is advantageous in obtaining the granular material 10 with high water absorption and safety at low cost. Moreover, since paper is an organic substance, the granular material 10 suitable for incineration disposal can be obtained. Especially when each granular material 10 consists only of papers, these effects become remarkable.

Each granular material 10 is accommodated in the packaging bag 20 in a compressed state. As a result, the excrement disposal material 1 can be transported and stored while keeping the volume of the excrement disposal material 1 small.

The inside of the packaging bag 20 is in a vacuum state. This makes it possible to easily achieve a state in which each granular material 10 is compressed within the packaging bag 20 .

The present invention is not limited to the above embodiments, and various modifications are possible. In the above embodiment, the case where each granular material 10 is mainly made of paper has been exemplified. However, each granule 10 may be made mainly of a material other than paper as long as it has compression restoring force. For example, a foam material may be used as the main material of each granular body 10 . In that case, each granule 10 may consist of a foam material only, or may consist of a foam material and another material. The foam material is preferably organic. Examples of foam materials include urethane foam and sponge. When the foam material is used in this way, there is an advantage that the granules 10 can be formed simply by cutting the foam material.

In the above embodiment, the case where the shape of the granular material 10 is spherical, cylindrical, or elliptical is exemplified. However, the shape of the granules 10 may be a prism such as a triangular prism, a quadrangular prism (including a cube and a rectangular parallelepiped).

In the above embodiment, the water-absorbent granules 10 that treat excrement by absorbing it are exemplified. However, the granules 10 may be water-permeable granules that treat excrement by permeating it. Here, there are two types of water-permeable granules: those in which excrement passes through the inside of the granules, and those in which excrement passes through the gaps between the granules. . An example of the latter is a granular material having water repellency.
