Abstract

An excrement treatment material includes a plurality of grains, and a packaging bag. The grains are grains for treating excrement. The plurality of grains are housed in the packaging bag. The packaging bag is provided with odor eliminating property or deodorizing property.

Claims (41)

1 . An excrement treatment material comprising:

a plurality of grains for treating excrement; and

a packaging bag in which the plurality of grains are housed,

wherein the packaging bag consists of an odor eliminating agent or a deodorizing agent,

wherein the grains for treating excrement have a core-coating structure,

wherein the core has a granular shape and is comprised of organic matter that absorbs and retains moisture of the excrement and is selected from the group consisting of paper, used tea leaves, plastic, and bean curd lees, and

wherein the coating on the core is comprised of an adhesive material that fully or partially coats the core.

2 . The excrement treatment material according to claim 1 ,

wherein the odor eliminating agent contains a metal that functions as the odor eliminating agent.

3 . The excrement treatment material according to claim 2 ,

wherein the metal is copper.

4 . The excrement treatment material according to claim 1 ,

wherein the deodorizing agent contains a porous material that functions as the deodorizing agent.

5 . The excrement treatment material according to claim 4 ,

wherein the porous material is organic matter.

6 . The excrement treatment material according to claim 5 ,

wherein the organic matter is coffee-extracted grounds or used tea leaves.

7 . The excrement treatment material according to claim 1 ,

wherein an additional odor eliminating agent or deodorizing agent is adhered to an inner surface of the packaging bag.

8 . The excrement treatment material according to claim 1 ,

wherein an additional odor eliminating agent or deodorizing agent is housed in the packaging bag.

9 . The excrement treatment material according to claim 8 ,

wherein the additional odor eliminating agent or deodorizing agent is housed in the packaging bag in a state of being apart from the plurality of grains.

10 . A method for manufacturing an excrement treatment material, the method comprising:

a grain forming step of forming a plurality of grains for treating excrement, the grains for treating excrement having a core-coating structure, wherein the core has a granular shape and is comprised of organic matter that absorbs and retains moisture of the excrement and is selected from the group consisting of paper, used tea leaves, plastic, and bean curd lees, and wherein the coating on the core is comprised of an adhesive material that fully or partially coats the core; and

a grain housing step of housing the plurality of grains formed in the grain forming step in a packaging bag,

wherein the packaging bag consists of an odor eliminating agent or a deodorizing agent.

11 . The method for manufacturing an excrement treatment material according to claim 10 ,

wherein the odor eliminating agent contains a metal that functions as the odor eliminating agent.

12 . The method for manufacturing an excrement treatment material according to claim 10 ,

wherein the deodorizing agent contains a porous material that functions as the deodorizing agent.

13 . The method for manufacturing an excrement treatment material according to claim 12 ,

wherein the porous material is organic matter.

14 . The method for manufacturing an excrement treatment material according to claim 10 ,

wherein an additional odor eliminating agent or deodorizing agent is adhered to an inner surface of the packaging bag.

15 . The method for manufacturing an excrement treatment material according to claim 14 , the method further comprising:

an inner surface processing step of making the additional odor eliminating agent or deodorizing agent adhere to the inner surface of the packaging bag prior to the grain housing step.

16 . The method for manufacturing an excrement treatment material according to claim 10 , the method further comprising:

an odor eliminating agent/deodorizing agent housing step of housing an additional odor eliminating agent or a deodorizing agent in the packaging bag.

17 . The method for manufacturing an excrement treatment material according to claim 16 ,

wherein in the odor eliminating agent/deodorizing agent housing step, the additional odor eliminating agent or deodorizing agent is housed in the packaging bag in a state of being apart from the plurality of grains.
